FACILITY INFORMATION Information describing the Orange County Sanitation District (hereinafter "OC San", "Permittee" or "Discharger") is summarized in Tables 1 and 2, and in sections I and II of the Fact Sheet (Attachment F). Section I of the Fact Sheet also includes information regarding the Facility's permit application. II. FINDINGS The California Regional Water Quality Control Board, Santa Ana Region (hereinafter "Santa Ana Water Board") and the United States Environmental Protection Agency, Region 9 (hereinafter "USEPA") find: A. Legal Authorities. This Order serves as waste discharge requirements (WDRs) pursuant to article 4, chapter 4, division 7 of the California Water Code (CWC; commencing with section 13260). This Order is also issued pursuant to section 402 of the federal Clean Water Act (CWA) (Public Law 92-500, as amended, 33 U.S.C. 1251 et seq.) and implementing regulations adopted by USEPA and chapter 5.5, division 7 of the CWC (commencing with section 13370). It shall serve as the State's National Pollutant Discharge Elimination System (NPDES) permit authorizing the Discharger to discharge into waters of the United States at the discharge locations described in Table 2, subject to the WDRs in this Order (hereinafter "Order"). The Order/Permit are consolidated under 40 CFR § 124.4(c)(2). Although Discharge Point 001 is beyond the limit of State-regulated ocean waters, effluent plume migration into State waters warrants joint regulation of the discharge by USEPA and the Santa Ana Water Board. Therefore, pursuant to 40 CFR § 124.4, this Order shall serve as a joint consolidated State and federal NPDES Permit authorizing the Discharger to discharge into waters of the United States at the discharge locations described in Table 2, subject to the limitations, conditions and all other requirements set forth herein (hereinafter "Order/Permit"). The Permit is both a federal permit and a state permit by operation of law. B. Background and Rationale for Requirements. The Santa Ana Water Board and USEPA developed the requirements in this Order/Permit based on information submitted as part of the application, through monitoring and reporting programs, and other available information. The Fact Sheet (Attachment F), which contains background information and rationale for the requirements in this Order/Permit, is hereby incorporated into and constitutes Findings for this Order/Permit. Attachments A through E and G though H are also incorporated into this Order/Permit. C. Permit Renewal Contingency. The Discharger's federal NPDES Permit renewal is contingent upon: 1. Determination by the U.S. Fish and Wildlife Service (USFWS) and the National Oceanic and Atmospheric Administration (NOAA) National Marine Fisheries Service (NMFS) that the discharge is consistent with the federal Endangered Species Act (ESA) of 1973, as amended (16 U.S. Code (U.S.C.) section 1531 et seq.); WASTE DISCHARGE REQUIREMENTS AND NPDES PERMIT 7 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS 2. Determination by the NOAA NMFS that the proposed discharge is consistent with the Magnuson-Stevens Fishery Conservation and Management Act (MSA) of 1976, as amended (16 U.S.C. section 1801 et seq.); 3. Determination by the California Coastal Commission (CCC) that the proposed discharge is consistent with the Coastal Zone Management Act (CZMA) of 1972, as amended (16 U.S.C. section 1451 et seq.); and 4. The Santa Ana Water Board's certification/concurrence that the discharge will comply with applicable State water quality standards. D. Notification of Interested Parties. The Santa Ana Water Board and USEPA have notified the Discharger and interested agencies and persons of their intent to jointly issue consolidated WDRs and NPDES Permit requirements; and has provided an opportunity to submit written comments and recommendations. Details of the notification are provided in the Fact Sheet and the joint public notice for this Order/Permit. E. Consideration of Public Comment. The USEPA considered all written comments pertaining to the discharge. The Santa Ana Water Board, in a public meeting, heard and considered all comments pertaining to the discharge. Details of the Santa Ana Water Board's Public Hearing are provided in the Fact Sheet (Attachment F). THEREFORE, IT IS HEREBY ORDERED, that this Order/Permit supersedes Order No. R8-2012-0035 except for enforcement purposes, and, in order to meet the provisions contained in division 7 of the Water Code (commencing with section 13000) and regulations adopted thereunder, and the provisions of the CWA and regulations and guidelines adopted thereunder, the Discharger shall comply with the requirements in this Order/Permit. This action in no way prevents the Santa Ana Water Board and/or USEPA from taking enforcement action for violations of the previous Order/Permit. III. DISCHARGE PROHIBITIONS A. The discharge of waste/pollutants in a manner or at locations that have not been specifically authorized by this Order/Permit is prohibited. B. The discharge of any radiological, chemical, or biological warfare agent or high-level radioactive waste into the ocean is prohibited. C. Waste shall not be discharged to designated Areas of Special Biological Significance, except as provided in Chapter III.E of the Ocean Plan (i.e., Implementation Provisions for Marine Managed Areas). D. Pipeline discharge of sludge to the ocean is prohibited by federal law; the discharge of municipal and industrial waste sludge directly to the ocean, or into a waste stream that discharges to the ocean, is prohibited by the California Ocean Plan. The discharge of sludge digester supernatant directly to the ocean, or to a waste stream that discharges to the ocean without further treatment, is prohibited. E. The bypassing of untreated wastes containing concentrations of pollutants in excess of those in Table 4 or Table 3 of the California Ocean Plan to the ocean is prohibited. WASTE DISCHARGE REQUIREMENTS AND NPDES PERMIT 8 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS F. The discharge of trash to surface waters of the State or the deposition of trash where it may be discharged into surface waters of the State is prohibited. G. Discharge at Discharge Point 001 (120" outfall) is prohibited when the discharge does not receive a minimum initial dilution of at least 181:1 (Dm = 180), as modeled assuming no currents. Compliance shall be achieved by proper operation and maintenance of the discharge outfall to ensure that it (or its replacement, in whole or part) is in good working order and is consistent with, or can achieve better mixing than, 181:1. The Discharger shall notify the Santa Ana Water Board and USEPA if outfall ports will be retrofitted, as the 181:1 dilution assumes all outfall ports are operational. H. Unless regulated by appropriate waste discharge requirements, the discharge to surface or groundwaters of waste which contains the following substances is prohibited: toxic substances or materials; pesticides; PCBs (polychlorinated biphenyls); mercury or mercury compounds; radioactive substances or material in excess of levels allowed by the California Code of Regulations. This list is not necessarily all-inclusive. I. The discharge of untreated sewage to any surface water stream, natural or man-made, or to any drainage system intended to convey storm water runoff to surface water streams is prohibited. J. The discharge of treated sewage to streams, lakes or reservoirs, or to tributaries thereto, which are designated MUN and which are used as a domestic water supply is prohibited unless approved by the California Department of Public Health. The discharge of treated sewage to waterbodies which are excepted from MUN (Basin Plan Table 3-1) but which are tributary to waters designated MUN and are used as a domestic water supply is prohibited unless the discharge of treated sewage to the drinking water supply is precluded or approved by the California Department of Public Health. K. The discharge of wastewater to a water of the United States from any locations other than Discharge Point 001 (120" outfall) is prohibited, except during the following situations: 1. Emergency discharge of disinfected secondary effluent and/or reverse osmosis (RO) concentrate to Discharge Point 002 (78" outfall) when the flow rate exceeds the hydraulic capacity of Discharge Point 001, provided that discharges through Discharge Point 001 (120" outfall) and discharges to Orange County Water District (OCWD)'s water recycling facilities are maximized to a functional capacity that is necessary to prevent infrastructure or equipment damage before wastewater is discharged through Discharge Point 002; 2. Emergency discharge of disinfected secondary effluent and/or RO concentrate to Discharge Point 003 (Santa Ana River overflow weirs) in the event of an extreme emergency (e.g., tsunami, earthquake, flood, and acts of war or terrorism) that precludes discharging all wastewater to Discharge Points 001 and 002, provided that discharges through Discharge Points 001 (120" outfall) and 002 (78" outfall) are maximized before wastewater is discharged through Discharge Point 003; or WASTE DISCHARGE REQUIREMENTS AND NPDES PERMIT 9 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS 3. Discharge of disinfected secondary effluent and/or RO concentrate to Discharge Point 002 (78" outfall) during planned essential maintenance or capital improvement projects to assure efficient operation of Discharge Point 001 (120" outfall) when there is no other feasible alternative. The Santa Ana Water Board Executive Officer and USEPA Water Division Director are notified of the pending discharge as soon as possible. During a planned diversion such as essential maintenance or capital improvement projects, this notification shall be submitted a minimum of 10 days prior to diverting flow to Discharge Point 002 (78" outfall), and include the rationale for the discharge, the expected time, date, and the duration of the discharge. Projects warranting such a diversion must be approved by the Santa Ana Water Board Executive Officer and USEPA Water Division Director prior to diverting flow to Discharge Point 002. The Discharger shall take all steps required by the Santa Ana Water Board Executive Officer or USEPA Water Division Director to minimize any harm resulting from the discharge. IV. EFFLUENT LIMITATIONS AND DISCHARGE SPECIFICATIONS A. Discharge Specifications — Discharge Points 001 and 002 1. Waste management systems that discharge to the ocean must be designed and operated in a manner that will maintain the indigenous marine life and a healthy and diverse marine community. 2. Waste discharged to the ocean must be essentially free of: Material that is floatable or will become floatable upon discharge; settleable material or substances that may form sediments which will degrade benthic communities or other aquatic life; substances which will accumulate to toxic levels in marine waters, sediments or biota; substances that significantly decrease the natural light to benthic communities and other marine life; and materials that result in aesthetically undesirable discoloration of the ocean surface. 3. Waste effluents shall be discharged in a manner which provides sufficient initial dilution (Dm = 180 for Discharge Point 001 and Dm = 36 for Discharge Point 002), with exception of radioactivity, to minimize the concentrations of substances not removed in the treatment. 4. Waste that contains pathogenic organisms or viruses should be discharged a sufficient distance from naturally occurring shellfishing and water contact sports are to maintain applicable bacterial standards without disinfection. Where conditions are such that an adequate distance cannot be attained, reliable disinfection in conjunction with a reasonable separation of the discharge point from the area of use must be provided. Disinfection procedures at Discharge Point 002 (78" outfall) that do not increase effluent toxicity and that constitute the least environmental and human hazard should be used. B.

CA0110604 COLLECTION SYSTEM & OUTFALLS performance data for the OC San's secondary treatment plants and are specified only as an indication of the treatment efficiency of the plants. The performance goals are not considered enforceable effluent limitations or standards for the regulation of discharge from the treatment facility. The Discharger shall maintain existing treatment levels and the effluent quality at or below the performance goal concentrations. Any two consecutive exceedances of the performance goals shall trigger an investigation into the cause of the exceedance. If the exceedance persists in three successive monitoring periods, the Discharger shall submit a written report to the Santa Ana Water Board and USEPA on the nature of the exceedance, the results of the investigation including the cause of the exceedance. The Santa Ana Water Board and USEPA may reopen the Order/Permit to modify any of the performance goals if the Discharger submits a request and demonstrates that the change is warranted, including results of completion of GWRS final expansion. B. Mass Emission Benchmarks — Discharge point 001 The following 12-month average mass emission benchmarks for Discharge Point 001 (120" outfall) are prescribed below in Table 7. For each parameter with a mass emission benchmark, the Discharger shall report the annual mass emission and the effluent concentrations and flows used to calculate the annual mass emission in the annual pretreatment report and annual receiving water monitoring report (effluent chapter). These mass emission benchmarks are not enforceable water quality-based effluent limitations. They may be re-evaluated and revised during the five-year permit term. For this Order/Permit, the mass emissions benchmarks (in metric tons per year; MT/yr) were determined based on 2015 through 2019 effluent mass emission and the Discharger's annual average influent flow of 206 MGD projected for 2025 (see section V of the fact sheet in Attachment F).

Surface Water Limitations The discharge of waste by the Discharger shall not cause a violation of the California Ocean Plan water quality objectives and USEPA water quality criteria specified below. Compliance shall be determined from samples collected at stations representative of the area within the waste field where initial dilution is completed. 1. Bacterial Characteristics a. State Water Board Water-Contact Objectives i. Within a zone bounded by the shoreline and a distance of 1,000 feet from the shoreline or the 30-foot depth contour, whichever is further from the shoreline, and in areas outside this zone used for water contact sports, as determined by the Santa Ana Water Board or USEPA (i.e., waters designated as REC-1), but including all kelp beds, the following bacterial water quality objectives shall be maintained throughout the water column: Fecal Coliform A 30-day geometric mean of fecal coliform density shall not exceed 200/100 mL, calculated based on the geometric mean of the five most recent samples from each site, and a single sample maximum shall not exceed 400/100 mL. Enterococci A 6-week rolling geometric mean of enterococci, calculated weekly, shall not exceed 30 CFU or MPN per 100 mL. The geometric mean value shall be applied based on a statistically sufficient number of samples, which is generally not less than five samples distributed over a 6-week period.

The Initial Dilution Zone of wastewater outfalls shall be excluded from designation as kelp beds for purposes of bacterial standards. Adventitious assemblages of kelp on waste discharge structures (e.g., outfall pipes and multiport diffusers) do not constitute kelp beds for purposes of bacterial standards. b. State Water Board Beach Notification Levels Minimum protective bacteriological standards for coastal waters adjacent to public beaches and for public water-contact sports areas in ocean waters are established in the California Code of Regulations, Title 17 (beginning at div. 1, ch. 5, section 7958 et seq.), which are not water quality objectives. When a public beach or public water-contact sports area fails to meet these standards, the California Department of Public Health or the local public health officer may post with warning signs or otherwise restrict use of the public beach or public water-contact sports area until the standards are met. The regulations impose more frequent monitoring and more stringent posting and closure requirements on certain high-use public beaches that are located adjacent to a storm drain that flows in the summer. c. State Water Board Shellfish Harvesting Standards At all areas where shellfish may be harvested for human consumption, as determined by the Santa Ana Water Board and USEPA, the following bacterial objectives shall be maintained throughout the water column: The median total coliform density shall not exceed 70 per 100 mL, and not more than 10 percent of the samples shall exceed 230 per 100 mL. d. USEPA Recreational Water Quality Criteria (RWQC) Ocean waters beyond the outer limit of the territorial sea shall not exceed the following RWQC for Enterococcus density beyond the zone of initial dilution in areas where primary contact recreation occurs. The 2012 RWQC describes the criteria are designed to protect "primary contact recreation", including swimming, bathing, surfing, water skiing, tubing, water play by children, and similar water contact activities where a high degree of bodily contact with the water, immersion and ingestion are likely (Recreational Water Quality Criteria, EPA-820-F-12-058, 2012, p. 6.). Estimated illness rate of 32 per 1,000 primary contact recreators: A 30-day geometric mean shall not exceed 30 CFU or MPN per 100 mL, which is calculated based on a statistically sufficient number of samples (generally not less than five samples equally spaced over any 30-day period).

I. Or as otherwise authorized by law. 2. Southern California Bight Monitoring Exchange The MRP (Attachment E) may be modified by the Santa Ana Water Board and USEPA to enable the Discharger to participate in comprehensive regional monitoring activities conducted in the Southern California Bight during the term of this permit. The intent of regional monitoring activities is to maximize the efforts of all monitoring partners using a cost-effective monitoring design and to best utilize the pooled scientific resources of the region. During these coordinated monitoring efforts, the WASTE DISCHARGE REQUIREMENTS AND NPDES PERMIT 27 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS Discharger's sampling and analytical effort may be reallocated to provide a regional assessment of the impact of wastewater discharges to the Southern California Bight; however, certain core elements (i.e., monthly water quality monitoring, quarterly REC-1 water quality monitoring, quarterly benthic monitoring, semi-annual trawl fish monitoring, and weekly Orange County Regional Shoreline REC-1 cooperative monitoring) shall remain unchanged. Anticipated modifications to the monitoring program will be coordinated so as to provide a comprehensive picture of the ecological and statistical significance of monitoring results and to determine cumulative impacts of various pollutant sources. If predictable relationships among the biological, water quality and effluent monitoring variables can be demonstrated, it may be appropriate to decrease the Discharger's monitoring effort. Conversely, the monitoring program may be intensified if it appears that the objectives cannot be achieved through the Discharger's existing monitoring program. These changes will improve the overall effectiveness of monitoring in the Southern California Bight. Minor changes may be made without further public notice. 3. Special Studies, Technical Reports and Additional Monitoring Requirements a. Toxicity Reduction Requirements If the discharge exceeds an effluent limitation for toxicity specified in Table 5 and 6, the Discharger shall conduct a Toxicity Reduction Evaluation (TRE) defined in Attachment A, in accordance with an approved TRE Work Plan, and take actions to mitigate the impact of the discharge and prevent recurrence of toxicity. A TRE is not an effluent limitation for toxicity. i. TRE Work Plan Within 90 days of the Order/Permit effective date, the Discharger shall prepare and submit a copy of their Initial Investigation Toxicity Reduction Evaluation (TRE) Workplan to the Santa Ana Water Board and USEPA for review and approval by the Santa Ana Water Board Executive Officer and USEPA Water Division Director. The TRE Work Plan must be developed in accordance with USEPA guidance, EPA manual Toxicity Reduction Evaluation Guidance for Municipal Wastewater Treatment Plants (EPA/ 833/B-99/002, 1999), and be of adequate detail to allow the Discharger to immediately initiate a TRE as required in this Provision. This plan shall outline the procedures for identifying the source(s) of, and reducing or eliminating effluent toxicity and shall describe the steps the Discharger intends to follow if toxicity is measured above an acute or chronic WET permit limit. The TRE Work Plan should include, at minimum: (a) A description of the investigation and evaluation techniques that would be used to identify potential causes and sources of the exceedance, effluent variability, and/or efficiency of the treatment system in removing toxic substances. This shall include a description of an accelerated chronic toxicity testing program; (b) A description of the methods to be used for investigating and maximizing WASTE DISCHARGE REQUIREMENTS AND NPDES PERMIT 28 ORANGE COUNTY SANITATION DISTRICT ORDER NO.

Accelerated Toxicity Monitoring Specifications and TRE/TIE Initiation When a WET permit limit is exceeded during regular toxicity monitoring, and the testing meets all test acceptability criteria, the Discharger shall initiate accelerated monitoring as required below. The Discharger shall initiate a TRE to address effluent toxicity if any WET testing results exceed the WET permit limit during accelerated monitoring. (a) If an acute or chronic WET permit limit is exceeded and the source(s) of toxicity is easily identified (e.g., a temporary plant upset), then the Discharger shall make necessary corrections to the facility and shall conduct one (1) additional toxicity test using the same species and test method. This test shall begin within 14 days of notification by the laboratory of the exceedance of the WET permit limit. If the additional toxicity test does not exceed the WET permit limit, then the Discharger may return to their regular testing frequency. (b) If an acute or chronic WET permit limit is exceeded and the source of toxicity is not known, then the Discharger shall conduct four (4) additional toxicity tests using the same species and test method, approximately every two weeks, over an eight(8) week period. This testing shall begin within 14 days of notification by the laboratory of the exceedance of the WET permit limit. The following protocol shall be used for accelerated monitoring and TRE initiation: (1) If none of the additional four (4) consecutive toxicity tests exceed the WET permit limit, then the Discharger may cease accelerated monitoring and resume their regular toxicity monitoring. However, notwithstanding the accelerated monitoring results, if there is adequate evidence of a pattern of effluent toxicity, the Santa Ana Water Board Executive Officer and/or USEPA Water Division Director may require that the Discharger initiate a TRE. (2) If one of the additional toxicity tests (in paragraphs ii(a) or ii(b) above) exceeds the WET permit limit, then, within 14 days of receipt of this test result, the Discharger shall cease accelerated monitoring and initiate a TRE using as guidance, based on the type of treatment facility, USEPA manual Toxicity Reduction Evaluation Guidance for Municipal Wastewater Treatment Plants (EPA/ 833/B-99/002, 1999). In conjunction, within 30 days of notification by the laboratory of any WASTE DISCHARGE REQUIREMENTS AND NPDES PERMIT 29 ORANGE COUNTY SANITATION DISTRICT ORDER NO.

(c) The Discharger may initiate a TIE as part of a THE to identify the causes of toxicity using the same species and test method and, as guidance, USEPA test method manuals: Toxicity Identification Evaluation: Characterization of Chronically Toxic Effluents, Phase I (EPA/600/6- 91/005F, 1992); Methods for Aquatic Toxicity Identification Evaluations, Phase II Toxicity Identification Procedures for Samples Exhibiting Acute and Chronic Toxicity (EPA/600/R-92/080, 1993); Methods for Aquatic Toxicity Identification Evaluations, Phase III Toxicity Confirmation Procedures for Samples Exhibiting Acute and Chronic Toxicity (EPA/600/R-92/081, 1993); and Marine Toxicity Identification Evaluation (TIE): Phase I Guidance Document (EPA/600/R-96-054, 1996). b. Dilution Model Update No later than 4 years after the effective date of this Order/Permit, the Discharger shall submit a work plan for an updated dilution modeling that is reflective of current operations, including the increase in RO concentrate that may be discharged upon completion of the groundwater replenishment system (GWRS) final expansion project. The purpose of the study is to determine initial dilution under a reasonable worst-case scenario (e.g., strongest density stratification and zero current). The discharger shall include explanation of the conditions and data used, assessment of compliance with applicable water quality objectives, and determination of an appropriate dilution ratio for each outfall. Specifically, the work plan shall include: • Model inputs and assumptions, • Describe trapping levels and any boundary effects in the observed range of the ambient density stratification, • Assume zero current, consistent with the California Ocean Plan, • Account for a decrease in flow and an increase in pollutant concentrations, • Include WET assessment using synthetic effluent to approximate future final conditions, and • Include a sensitivity analysis for how different inputs affect the initial dilution, including effluent temperature and density. c.

Effluent Limitations Compliance with the effluent limitations contained in section IV of this Order/Permit shall be determined as specified below. 1. Sufficient sampling and analysis shall be required to determine compliance with the effluent limitation. If the analytical result of any single sample (daily discharge) monitored monthly, or less frequently, exceeds the AMEL (or 6-month median effluent limitation), then the Discharger shall increase the monitoring frequency to weekly until compliance with the effluent limitation is demonstrated. 2. Compliance with Effluent Limitations expressed as Single Constituents Dischargers are out of compliance with the effluent limitation if the concentration of the pollutant in the monitoring sample is greater than the effluent limitation and greater than or equal to the reported Minimum Level (i.e., ML or RL). 3. Compliance with Effluent Limitations expressed as Sum of Several Constituents Dischargers are out of compliance with an effluent limitation which applies to the sum of a group of chemicals (e.g., PCBs) if the sum of the individual pollutant concentrations is greater than the effluent limitation. Individual pollutants of the group will be considered to have a concentration of zero if the constituent is reported as ND or DNQ. 4. Multiple Sample Data When determining compliance with a measure of central tendency (arithmetic mean, geometric mean, median, etc.) of multiple sample analyses and the data set contains one or more reported determinations of DNQ or ND, the Discharger shall compute the median in place of the arithmetic mean in accordance with the following procedure: a. The data set shall be ranked from low to high, ranking the reported ND determinations lowest, DNQ determinations next, followed by quantified values (if any). The order of the individual ND or DNQ determinations is unimportant. b. The median value of the data set shall be determined. If the data set has an odd number of data points, then the median is the middle value. If the data set has an even number of data points, then the median is the average of the two values around the middle unless one or both of the points are ND or DNQ, in which case the median value shall be the lower of the two data points where DNQ is lower than a value and ND is lower than DNQ. 5. Average Monthly Effluent Limitation (AMEL) If the average (or when applicable, the median determined by subsection 4 above for multiple sample data reduction) of daily discharges over a calendar month exceeds (is higher than) the AMEL for a given parameter, an alleged violation will be WASTE DISCHARGE REQUIREMENTS AND NPDES PERMIT 36 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS flagged and the Discharger will be considered out of compliance for each day of that month for that parameter (e.g., resulting in 31 days of non-compliance in a 31-day month). However, an alleged violation of the AMEL will be considered one violation for the purpose of assessing State mandatory minimum penalties. If only a single sample is collected during the calendar month and the analytical result for that sample exceeds the AMEL, the Discharger may be considered out of compliance for that calendar month. For those average monthly effluent limitations that are based on the 6-month median water quality objectives in the 2019 Ocean Plan, the daily value used to calculate these average monthly values for intermittent discharges, shall be considered to equal zero for days on which no discharge occurred. The Discharger will only be considered out of compliance for days when the discharge occurs. If no sample (daily discharge) is taken over any one calendar month, no compliance determination can be made for that month with respect to effluent violation determination, but compliance determination can be made for that month with respect to reporting violation determination. A month will begin on the first day of the calendar month and end on the last day of the calendar month, in order to calculate and report a consecutive (uninterrupted) average value for the AMEL for a calendar month. 6. Average Weekly Effluent Limitation (AWEL) If the average (or when applicable, the median determined by subsection 4 above for multiple sample data reduction) of daily discharges over a calendar week exceeds (is higher than) the AWEL for a given parameter, an alleged violation will be flagged and the Discharger will be considered out of compliance for each day of that week for that parameter (e.g., resulting in seven days of non-compliance). However, an alleged violation of the AWEL will be considered one violation for the purpose of assessing State mandatory minimum penalties. The average of daily discharges over a calendar week that exceeds the AWEL for a parameter will be considered out of compliance for that week only. If only a single sample is collected during the calendar week and the analytical result for that sample exceeds the AWEL, the Discharger will be considered out of compliance for that calendar week. If no sample (daily discharge) is taken over a calendar week, no compliance determination can be made for that week with respect to effluent violation determination, but compliance determination can be made for that week with respect to reporting violation determination. A calendar week will begin on Sunday and end on Saturday. Partial calendar weeks at the end of the calendar month will be carried forward to the next month in order to calculate and report a consecutive seven-day average value for the AWEL on Saturday. 7. Maximum Daily Effluent Limitation (MDEL) If a daily discharge on a calendar day exceeds (is higher than) the MDEL for a given parameter, an alleged violation will be flagged and the Discharger will be considered out of compliance for that day for that parameter. If no sample (daily discharge) is taken over a calendar day, no compliance determination can be made for that day WASTE DISCHARGE REQUIREMENTS AND NPDES PERMIT 37 ORANGE COUNTY SANITATION DISTRICT ORDER NO.

Instantaneous Minimum Effluent Limitation If the analytical result of a single grab sample exceeds (is lower than) the instantaneous minimum effluent limitation for a given parameter, an alleged violation will be flagged and the Discharger will be considered out of compliance for that single sample for that parameter. Non-compliance for each single grab sample will be considered separately (e.g., the analytical results of two grab samples taken over a calendar day that are lower than the instantaneous minimum effluent limitation would result in two instances of non-compliance with the instantaneous minimum effluent limitation). 9. Instantaneous Maximum Effluent Limitation If the analytical result of a single grab sample exceeds (is higher than) the instantaneous maximum effluent limitation for a given parameter, an alleged violation will be flagged and the Discharger will be considered out of compliance for that single sample for that parameter. Non-compliance for each single grab sample will be considered separately (e.g., the analytical results of two grab samples taken over a calendar day that both are higher than the instantaneous maximum effluent limitation would result in two instances of non-compliance with the instantaneous maximum effluent limitation). 10.Six-month Median Effluent Limitation (i.e., 180-day Median Effluent Limitation) If the median of daily discharges over any 180-day period exceeds (is higher than) the 6-month median effluent limitation for a given parameter, an alleged violation will be flagged and the Discharger will be considered out of compliance for each day of that 180-day period (e.g., resulting in 180 days of non-compliance in any 180-day period). The next assessment of compliance will occur when the next sample is taken. If only a single sample is collected during a given 180-day period and the analytical result for that sample exceeds the six-month median, the Discharger will be considered out of compliance for the 180-day period. If no sample (daily discharge) is taken over a 180-day period, no compliance determination can be made for that period with respect to effluent violation determination, but compliance determination can be made for that period with respect to reporting violation determination. 11.Mass and Concentration Limitations Compliance with mass and concentration effluent limitations for the same parameter shall be determined separately with their respective limitations.

If grab samples are taken, "Ci" is the constituent concentration (mg/L) and "Qi" is the flow rate (MGD) associated with each "N" grab sample. If composite samples are taken, "Ci" is the constituent concentration (mg/L) in each composite sample and "Qi" is the average flow rate (MGD) during the period over which sample compositing occurs. The daily discharge concentration of a constituent shall be determined from the flow- weighted average of the same constituent in the combined waste stream using the following equation: N Daily discharge concentration = Q C Qt i=1 in which "N" is the number of component waste streams. "Ci" is the constituent concentration (mg/L) and "Qi" is the flow rate (MGD) associated with each "N" component waste stream. "Qt" is the total flow rate of the combined waste stream. 13.Bacterial Standards and Analysis a.

Areas of Special Biological Significance (ASBS) Those areas designated by the State Water Board as ocean areas requiring protection of species or biological communities to the extent that maintenance of natural water quality is assured. All Areas of Special Biological Significance are also classified as a subset of STATE WATER QUALITY PROTECTION AREAS (SWQPA). ASBS are also referred to as State Water Quality Protection Areas —Areas of Special Biological Significance (SWQPA-ASBS). Average Monthly Effluent Limitation (AMEL) Means the highest allowable average of daily discharges over a calendar month, calculated as the sum of all "daily discharges" measured during a calendar month divided by the number of "daily discharges" measured during that month. (40 CFR § 122.2) Average Weekly Effluent Limitation (AWEL) Means the highest allowable average of daily discharges over a calendar week (Sunday through Saturday), calculated as the sum of all daily discharges measured during a calendar week divided by the number of"daily discharges" measured during that week.

For a composite sample, if the duration of the discharge is less than 24 hours but greater than 8 hours, at least eight flow-weighted individual sample portions shall be taken during the duration of the discharge and composited. For a discharge duration of 8 hours or less, eight individual "grab samples" may be substituted and composited. Daily Discharge Daily Discharge is defined as either (1) the total mass of the constituent discharged over the calendar day (12:00 am through 11:59 pm) or any 24-hour period that reasonably represents a calendar day for purposes of sampling (as specified in the permit), for a constituent with limitations expressed in units of mass; or (2) the unweighted arithmetic mean measurement of the constituent over the day for a constituent with limitations expressed in other units of measurement (e.g., concentration). The daily discharge may be determined by the analytical results of a composite sample taken over the course of one day (a calendar day or other 24-hour period defined as a day), or by the arithmetic mean of analytical results from one or more grab samples taken over the course of one day. For composite sampling, if one day is defined as a 24-hour period other than a calendar day, the analytical result for the 24-hour period will be considered as the result for the calendar day in which the 24-hour period ends.

Dredged Material Any material excavated or dredged from the navigable waters of the United States, including material otherwise referred to as "spoil". Eelgrass Beds Are aggregations of the aquatic plant species of the genus Zostera. Enclosed Bays Are indentations along the coast which enclose an area of oceanic water within distinct headlands or harbor works. Enclosed bays include all bays where the narrowest distance between headlands or outermost harbor works is less than 75 percent of the greatest dimension of the enclosed portion of the bay. This definition includes but is not limited to: Humboldt Bay, Bodega Harbor, Tomales Bay, Drakes Estero, San Francisco Bay, Morro Bay, Los Angeles Harbor, Upper and Lower Newport Bay, Mission Bay, and San Diego Bay. Enclosed bays do not include inland surface waters or ocean waters. Endosulfan Shall mean the sum of endosulfan-alpha and -beta and endosulfan sulfate. Estuaries and Coastal Lagoons Are waters at the mouths of streams that serve as mixing zones for fresh and ocean waters during a major portion of the year. Mouths of streams that are temporarily separated from the ocean by sandbars shall be considered as estuaries. Estuarine waters will generally be considered to extend from a bay or the open ocean to the upstream limit of tidal action but may be considered to extend seaward if significant mixing of fresh and salt water occurs in the open coastal waters.

Estuaries do not include inland surface waters or ocean waters. Facility or Activity Means any NPDES "point source" or any other facility or activity (including land or appurtenances thereto) this is subject to regulation under the NPDES program. (40 CFR § 122.2) Geometric Mean (GM) Is a type of mean or average that indicates the central tendency or typical value of a set of numbers by using the product of their values (as opposed to the arithmetic mean which uses their sum).

HCH Shall mean the sum of the alpha, beta, gamma (lindane) and delta isomers of hexachlorocyclohexane. Indicator Bacteria Includes total coliform bacteria, fecal coliform bacteria (or E. coli) and/or Enterococcus bacteria. Initial Dilution Is the process which results in the rapid and irreversible turbulent mixing of wastewater with ocean water around the point of discharge. For a submerged buoyant discharge, characteristic of most municipal and industrial wastes that are released from the submarine outfalls, the momentum of the discharge and its initial buoyancy act together to produce turbulent mixing. Initial dilution in this case is completed when the diluting wastewater ceases to rise in the water column and first begins to spread horizontally. For shallow water submerged discharges, surface discharges, and non-buoyant discharges, characteristic of cooling water wastes and some individual discharges, turbulent mixing results primarily from the momentum of discharge. Initial dilution, in these cases, is considered to be completed when the momentum induced velocity of the discharge ceases to produce significant mixing of the waste, or the diluting plume reaches a fixed distance from the discharge to be specified by the Santa Ana Water Board and/or USEPA, whichever results in the lower estimate for initial dilution. Instantaneous Maximum Effluent Limitation The highest allowable value for any single grab sample or aliquot (i.e., each grab sample or aliquot is independently compared to the instantaneous maximum effluent limitation). Instantaneous Minimum Effluent Limitation The lowest allowable value for any single grab sample or aliquot (i.e., each grab sample or aliquot is independently compared to the instantaneous minimum effluent limitation).

See also, DREDGED MATERIAL. Maximum Daily Effluent Limitation (MDEL) The highest allowable daily discharge of a pollutant, over a calendar day (or 24-hour period) (40 CFR § 122.2). For pollutants with limitations expressed in units of mass, the daily discharge is calculated as the total mass of the pollutant discharged over the day. For pollutants with limitations expressed in other units of measurement, the daily discharge is calculated as the arithmetic mean measurement of the pollutant over the day. Also, Maximum Daily Discharge Limitation (MDDL). Median The middle measurement in a set of data. The median of a set of data is found by first arranging the measurements in order of magnitude (either increasing or decreasing order). If the number of measurements (n) is odd, then the median = X(n+1)/2. If n is even, then the median = (Xn/2 + X(n/2)+1)/2 (i.e., the midpoint between the n/2 and n/2+1). Method Detection Limit (MDL) Is the minimum measured concentration of a substance that can be reported with 99 percent confidence that the measured concentration is distinguishable from method blank results, as defined in 40 CFR § 136, Appendix B. Minimum Level (ML) Is the concentration at which the entire analytical system must give a recognizable signal and acceptable calibration point. The ML is the concentration in a sample that is equivalent to the concentration of the lowest calibration standard analyzed by a specific analytical procedure, assuming that all the method-specified sample weights, volumes and processing steps have been followed. Mixing Zone Mixing Zone is a limited volume of receiving water that is allocated for mixing with a wastewater discharge where water quality criteria can be exceeded without causing adverse effects to the overall water body.

The goal of the PMP shall be to reduce all potential sources of the 2019 Ocean Plan Table 3 pollutants through pollutant minimization (control) strategies, including pollution prevention measures as appropriate, to maintain the effluent concentration at or below the water quality-based effluent limitation. Pollution prevention measures may be particularly appropriate for persistent bioaccumulative priority pollutants where there is evidence that beneficial uses are being impacted. The Santa Ana Water Board and USEPA may consider cost effectiveness when establishing the requirements of a PMP. The completion and implementation of a Pollution Prevention Plan, if required pursuant to Water Code section 13263.3(d), shall be considered to fulfill the PMP requirements. Pollution Prevention Any action that causes a net reduction in the use or generation of a hazardous substance or other pollutant that is discharged into water and includes, but is not limited to, input change, operational improvement, production process change, and product reformulation (as defined in CWC section 13263.3). Pollution prevention does not include actions that merely shift a pollutant in wastewater from one environmental medium to another environmental medium, unless clear environmental benefits of such an approach are identified to the satisfaction of the State Water Resources Control Board (State Water Board), Santa Ana Water Board, or USEPA. Publicly-Owned Treatment Works (POTWs) A treatment works as defined by section 212 of the CWA, which is owned by a State or municipality (as defined by section 502(4) of the Act).

The ML is based on the proper application of method-specific analytical procedures and the absence of any matrix interferences. Other factors may be applied to the ML depending on the specific sample preparation steps employed. For example, the treatment typically applied where there are matrix-effects is to dilute the sample or sample aliquot by a factor of ten. In such cases, this additional factor must be applied to the ML in the computation of the reported ML. (See Chapter III.C.6 of the 2019 Ocean Plan.). Salinity Is a measure of the dissolved salts in a volume of water. For the purposes of the Ocean Plan, salinity shall be measured using a standard method approved by the Santa Ana Water Board ATTACHMENT A- DEFINITIONS A-7 ORANGE COUNTY SANITATION DISTRICT ORDER NO.

(33 USC 1318(a)(4)(b); 40 CFR § 122.41(i)(4); CWC 13267, 13383.) G. Bypass 1. Definitions a. "Bypass" means the intentional diversion of waste streams from any portion of a treatment facility. (40 CFR § 122.41(m)(1)(i).) b. "Severe property damage" means substantial physical damage to property, damage to the treatment facilities which causes them to become inoperable, or substantial and permanent loss of natural resources that can reasonably be expected to occur in the absence of a bypass. Severe property damage does not mean economic loss caused by delays in production. (40 CFR § 122.41(m)(1)(ii).) 2. Bypass not exceeding limitations. The Discharger may allow any bypass to occur which does not cause effluent limitations to be exceeded, but only if it is also for essential maintenance to assure efficient operation. These bypasses are not subject to the provisions listed in Standard Provisions — Permit Compliance I.G.3, I.GA, and I.G.5. (40 CFR § 122.41(m)(2).) 3. Prohibition of bypass. Bypass is prohibited, and the Santa Ana Water Board/USEPA may take enforcement action against a Discharger for bypass, unless (40 CFR § 122.41(m)(4)(i)): a. Bypass was unavoidable to prevent loss of life, personal injury, or severe property damage (40 CFR § 122.41(m)(4)(i)(A)); ATTACHMENT D- STANDARD PROVISIONS D-3 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS b. There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities, retention of untreated wastes, or maintenance during normal periods of equipment downtime. This condition is not satisfied if adequate back-up equipment should have been installed in the exercise of reasonable engineering judgment to prevent a bypass that occurred during normal periods of equipment downtime or preventive maintenance (40 CFR § 122.41(m)(4)(i)(B)); and c. The Discharger submitted notices as required under Standard Provisions — Permit Compliance I.G.5. (40 CFR § 122.41(m)(4)(i)(C).) 4. The Santa Ana Water Board/USEPA may approve an anticipated bypass, after considering its adverse effects, if the Santa Ana Water Board/USEPA determines that it will meet the three conditions listed in Standard Provisions — Permit Compliance I.G.3. (40 CFR § 122.41(m)(4)(ii).) 5. Notice a. Anticipated bypass. If the Discharger knows in advance of the need for a bypass, it shall submit prior notice, if possible, at least ten days before the date of the bypass. The notice shall be sent to the Santa Ana Water Board and USEPA. As of December 21, 2025 all notices submitted in compliance with this section must be submitted electronically by the Discharger to the Santa Ana Water Board and USEPA or initial recipient, as defined in 40 CFR § 127.2(b), in compliance with this section and 40 CFR § 3 (including, in all cases, subpart D to part 3), 122.22 and part 127. Part 127 is not intended to undo existing requirements for electronic reporting. Prior to this date, and independent of part 127, the Discharger may be required to report electronically if specified by a particular Order/Permit or if required to do so by State law. (40 CFR § 122.41(m)(3)(i).) b. Unanticipated bypass. The Discharger shall submit a notice of an unanticipated bypass as required in Attachment D. Standard Provisions — Reporting V.E (24- hour notice). As of December 21, 2025 all notices submitted in compliance with this section must be submitted electronically by the Discharger to the Santa Ana Water Board and USEPA or initial recipient, as defined in 40 CFR § 127.2(b), in compliance with this section and 40 CFR § 3 (including, in all cases, subpart D to part 3), 122.22 and part 127. Part 127 is not intended to undo existing requirements for electronic reporting. Prior to this date, and independent of part 127, the Discharger may be required to report electronically if specified by a particular Order/Permit or if required to do so by State law. (40 CFR § 122.41(m)(3)(ii).) H. Upset Upset means an exceptional incident in which there is unintentional and temporary noncompliance with technology based permit effluent limitations because of factors beyond the reasonable control of the Discharger. An upset does not include noncompliance to the extent caused by operational error, improperly designed ATTACHMENT D- STANDARD PROVISIONS D-4 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS treatment facilities, inadequate treatment facilities, lack of preventive maintenance, or careless or improper operation. (40 CFR § 122.41(n)(1).) 1. Effect of an upset. An upset constitutes an affirmative defense to an action brought for noncompliance with such technology based permit effluent limitations if the requirements of Standard Provisions — Permit Compliance I.H.2 are met. No determination made during administrative review of claims that noncompliance was caused by upset, and before an action for noncompliance, is final administrative action subject to judicial review. (40 CFR § 122.41(n)(2).) 2. Conditions necessary for a demonstration of upset. A Discharger who wishes to establish the affirmative defense of upset shall demonstrate, through properly signed, contemporaneous operating logs, or other relevant evidence that (40 CFR § 122.41(n)(3)): a. An upset occurred and that the Discharger can identify the cause(s) of the upset (40 CFR § 122.41(n)(3)(i)); b. The permitted facility was at the time being properly operated (40 CFR § 122.41(n)(3)(ii)); and c. The Discharger submitted notice of the upset as required in Standard Provisions — Reporting V.E.2.b (24-hour notice) (40 CFR § 122.41(n)(3)(iii)). d. The Discharger complied with any remedial measures required under Standard Provisions — Permit Compliance I.C. (40 CFR § 122.41(n)(3)(iv).) 3. Burden of proof. In any enforcement proceeding, the Discharger seeking to establish the occurrence of an upset has the burden of proof. (40 CFR § 122.41(n)(4).) II. STANDARD PROVISIONS — PERMIT ACTION A. General This Order/Permit may be modified, revoked and reissued, or terminated for cause. The filing of a request by the Discharger for Order/Permit modification, revocation and reissuance, or termination, or a notification of planned changes or anticipated noncompliance does not stay any Order/Permit condition. (40 CFR § 122.41(f).) B. Duty to Reapply If the Discharger wishes to continue an activity regulated by this Order/Permit after the expiration date of this Order/Permit, the Discharger must apply for and obtain a new Order/Permit. (40 CFR § 122.41(b).) C. Transfers This Order/Permit is not transferable to any person except after notice to the Santa Ana Water Board/USEPA. The Santa Ana Water Board/USEPA may require modification or revocation and reissuance of the Order/Permit to change the name of the Discharger and incorporate such other requirements as may be necessary under the CWA and CWC.

California Water Code (CWC) sections 13267 and 13383 also authorize the Santa Ana Water Board to establish monitoring, inspection, entry, reporting, and recordkeeping requirements. This MRP establishes monitoring, reporting, and recordkeeping requirements that implement federal and California laws and/or regulations. The Discharger shall comply with this MRP of this Order/Permit. I. GENERAL MONITORING PROVISIONS A. The Santa Ana Water Board and USEPA, working with other groups, have developed a comprehensive basis for effluent and receiving water monitoring appropriate to large publicly-owned treatment works (POTWs) discharging to waters of the Southern California Bight. This effort has culminated in the publication by the Southern California Coastal Water Research Project (SCCWRP) of the Model Monitoring Program guidance document (Schiff, K.C., J.S. Brown and S.B. Weisberg. 2001. Model Monitoring Program for Large Ocean Dischargers in Southern California. SCCWRP Tech. Rep. #357. Southern California Coastal Water Research Project, Westminster, CA. 101 pp.). This guidance provides the principles, framework and recommended design for effluent and receiving water monitoring elements that have guided development of the monitoring program described below. B. This conceptual framework along with the California Ocean Plan has three components that comprise a range of spatial and temporal scales: (1) core monitoring; (2) regional monitoring; and (3) strategic process studies. 1. Core Monitoring. Core monitoring is local in nature and focuses on monitoring trends in quality and effects of the point source discharge. This includes discharge monitoring, as well as some aspects of receiving water monitoring. Core monitoring results for the effluent shall be submitted on monthly Discharge Monitoring Reports/State Monitoring Reports (DMR/SMR) and summarized in the annual receiving water monitoring report if needed. Core monitoring results for receiving water, including annotated QA/QC findings, shall be described and summarized in the annual receiving water monitoring report, due by March 15th of each year, for the previous fiscal year (July 1 through June 30). The annual receiving water monitoring report shall include the specified parameters for each station along with more detailed statistical comparisons, including analyses to elucidate spatial and temporal trends in the data, and in relation to the wastewater plume. Statistical methods shall include, but are not limited to, various multivariate techniques such as cluster analysis, ordination, and regression. The applicability and choice of statistical methods shall be explained in the report. 2. Regional Monitoring. Regional monitoring is focused on questions best answered by a region-wide approach that incorporates coordinated survey design and sampling techniques. Key components of regional monitoring include elements to address pollutant mass emission estimates, public health concerns, monitoring trends in natural resources, assessment of regional impacts from all contaminant ATTACHMENT E- MONITORING AND REPORTING PROGRAM E-3 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS sources, and beneficial use protection. The final designs of regional monitoring programs are developed by means of steering and technical committees comprised of participating agencies. For each component of regional monitoring, this Order/Permit specifies the required degree and nature of participation by Orange County Sanitation District (OC San), based upon its past participation in regional monitoring programs. The degree and nature of OC San's participation in regional monitoring programs shall be briefly described and summarized in the annual receiving water monitoring report. Each year, as part of the annual receiving monitoring report, the Discharger shall provide an informational report summarizing to date its contributing activities towards coordinated implementation of regional monitoring programs. Although participation in regional monitoring programs is required under this Order/Permit, revisions to Attachment E, at the direction of the Santa Ana Water Board and USEPA, may be necessary to accomplish the goals of regional monitoring. 3. Strategic Process Studies. Strategic process studies are focused on refined questions regarding specific effects or development of monitoring techniques and are anticipated to be of short duration and/or small scale, although multi-year studies may be needed. Questions regarding discharge or receiving water quality, discharge impacts, ocean processes in the area of the discharge, or development of techniques for monitoring the same, arising out of the results of core, regional monitoring, or other relevant studies shall be pursued through these studies. These studies are by nature ad hoc and, typically, cannot be anticipated in advance of the five-year permit cycle. Monitoring efforts, status of in-progress studies, and summary results for completed strategic process studies shall be briefly described and summarized in the annual receiving water monitoring report. In the spring, beginning in 2022 and continuing every-other year during the term of this Order/Permit, the Discharger, Santa Ana Water Board, and USEPA shall consult to determine the need for strategic process studies. By October 1st, the Discharger shall submit proposals to the Santa Ana Water Board and USEPA for the following fiscal year's (July 1 through June 30) monitoring effort, or a letter explaining why no special studies are proposed. Final scopes of work, including reporting schedules, shall be presented by the Discharger at a spring meeting with Santa Ana Water Board and USEPA to obtain Santa Ana Water Board and USEPA approval. Upon approval, the Discharger shall implement its strategic process studies. C. Every five years SCCWRP coordinates receiving water regional monitoring within the Southern California Bight and compiles monitoring data collected by the dischargers and other participating entities. The sixth regional monitoring program (Bight '18) occurred primarily during the summer of 2018. The next (seventh) regional monitoring program (Bight '23) is expected to take place during 2023. While participation in regional monitoring programs is required under this Order/Permit, revisions to the Discharger's monitoring program at the direction of the Santa Ana Water Board and ATTACHMENT E- MONITORING AND REPORTING PROGRAM E-4 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS USEPA may be necessary to accomplish the goals of regional monitoring or to allow the performance of special studies to investigate regional or site-specific water issues of concern. These revisions may include a reduction or increase in the number of parameters to be monitored, the frequency of monitoring, or the number and size of samples to be collected, which are applicable to receiving water monitoring program only. Such changes shall be authorized by the Santa Ana Water Board Executive Officer and USEPA Director upon written notification to the Discharger. Permittee participation in regional monitoring programs is required as a condition of this Order/Permit. The Discharger shall complete collection and analysis of samples in accordance with the schedule established by the Steering Committee directing the Bight-wide regional monitoring surveys. The level of participation shall be similar to that provided by the Discharger in previous regional surveys conducted in 1994, 1998, 2003, 2008, 2013, and 2018. D. All plant samples shall be representative of the waste discharge under conditions of peak load. Results of quarterly, semiannual, and annual analyses shall be reported by the due date specified in Table E-16 of the MRP. Should there be instances when monitoring could not be performed during these specified months, the Discharger must notify the Santa Ana Water Board and USEPA, state the reason why monitoring could not be conducted, and obtain approval from the Santa Ana Water Board and USEPA for an alternate schedule. E. Pollutants shall be analyzed using the analytical methods described in 40 CFR § 136; or where no methods are specified for a given pollutant, by methods approved by the Santa Ana Water Board, the State Water Board, and/or USEPA. If more than one analytical test method is listed for a given parameter, the Discharger must select from the listed methods and corresponding Minimum Level. USEPA published regulations for the Sufficiently Sensitive Methods Rule (SSM Rule) which became effective September 18, 2015. For the purposes of monitoring and reporting under the NPDES program, when more than one test procedure is approved under 40 CFR § 136 for the analysis of a pollutant or pollutant parameter, the test procedure must be sufficiently sensitive as defined at 40 CFR § 122.21(e)(3) and 122.44(i)(1)(iv). A USEPA-approved analytical method is sufficiently sensitive where: 1. The ML is at or below both the level of the applicable water quality criterion/objective and the permit limitation or performance goal for the measured pollutant or pollutant parameter; or 2. In permit applications, the ML is above the applicable water quality criterion/objective, but the amount of the pollutant or pollutant parameter in a facility's discharge is high enough that the method detects and quantifies the level of the pollutant or pollutant parameter in the discharge; or 3. The method has the lowest ML of the USEPA-approved analytical methods where none of the USEPA-approved analytical methods for a pollutant can achieve the MLs necessary to assess the need for effluent limitations or to monitor compliance with a permit limitation.

CA0110604 COLLECTION SYSTEM & OUTFALLS The MLs in Ocean Plan Appendix II remain applicable. However, there may be situations when analytical methods are published with MLs that are more sensitive than the MLs for analytical methods listed in the Ocean Plan. For instance, USEPA Method 1631 E for mercury is not currently listed in Ocean Plan Table II, but it is published with an ML of 0.5 ng/L that makes it a sufficiently sensitive analytical method. F. In conformance with federal regulations 40 CFR § 122.45(c), analyses to determine compliance with the effluent limitations for metals shall be conducted using the total recoverable method. For chromium (III) and (VI), the Discharger may, at its option, meet both the chromium (III) and the chromium (VI) limitations by analyzing for total recoverable chromium. G. Water/wastewater samples must be analyzed within allowable holding time limits as specified in 40 CFR § 136.3. All quality assurance/quality control (QA/QC) analyses must be run in the same preparation and analytical batches in which samples are actually analyzed. The Discharger shall retain the QA/QC documentation in its files and make available for inspection and/or submit this documentation when requested by the Santa Ana Water Board and/or USEPA. Proper chain of custody procedures must be followed, and a copy of this documentation shall be submitted with the monthly report. H. If the Discharger samples and performs analyses (other than for process/operational control, startup, research, or equipment testing) on any influent, effluent, or receiving water constituent more frequently than required by this Order/Permit using approved analytical methods, the results of those analyses shall be included in the monitoring report. These results shall be reflected in the calculation of the average (or median) used in demonstrating compliance with limitations set forth in this Order/Permit. I. All monitoring instruments and devices used by the Discharger to fulfill the prescribed monitoring program shall be properly maintained and calibrated as necessary to ensure their continued accuracy. In the event that continuous monitoring equipment is out of service for greater than a 24-hour period, the Discharger shall obtain a representative grab sample each day the equipment is out of service. The Discharger shall correct the cause(s) of failure of the continuous monitoring equipment as soon as practicable. In its monitoring report, the Discharger shall specify the period(s) during which the equipment was out of service and, if the problem has not been corrected, shall identify the steps which the Discharger is taking or proposes to take to bring the equipment back into service and the schedule for these actions. J. For every item of monitoring data where the requirements are not met, the monitoring report shall include a statement discussing the reasons for noncompliance, the actions undertaken or proposed that will bring the discharge into full compliance with requirements at the earliest time and an estimate of the date when the Discharger will be in compliance. The Discharger shall notify the Santa Ana Water Board and USEPA by letter when compliance with the time schedule has been achieved. K. Laboratory Certification. Laboratories analyzing monitoring samples shall be certified by the State Water Board, Environmental Laboratory Accreditation Program (ELAP), in accordance with CWC section 13176, and must include QA/QC data in their reports.

In order for the analytical method to be acceptable, the recovery of free cyanide from metal complexes must be comparable to that achieved by the approved method in 40 CFR § 136. 5 See Attachment A— Definitions. 6 Radioactivity: The following methods shall be used: USEPA Method 900.0 or Standard Methods 7110B for gross alpha and gross beta; USEPA Method 903.0 or 903.1 for radium-226; USEPA Method 904.0 for radium-228; USEPA Method 906.0 for tritium; USEPA Method 905.0 for strontium-90; and USEPA Method 908.0, 908.1, or 200.8 for uranium. Analysis for combined radium-226 & 228 shall be conducted only if gross alpha or gross beta results for the same sample exceed the stipulated criteria. If combined radium-226 & 228 exceeds the stipulated criteria, then analyze for tritium, strontium-90, and uranium. Note that as of February 2021, the stipulated criteria for gross alpha, gross beta, and radium-226 & 228 are 15 pCi/L, 50 pCi/L, and 5 pCi/L, respectively. These criteria are prospective, including future changes to any incorporated provisions of federal law, as the changes take effect. Tributyltin: SM 6710B or other improved methods approved by the Santa Ana Water Board and USEPA shall be used to analyze tributyltin in wastewater. 8 Chlordane: The Discharger may temporarily suspend the monitoring requirements for alpha- and gamma-chlordene, if analytical standards for these compounds are not available. However, the Discharger is required to resume detection and quantification practices as soon as standards become available. 9 1,3-dichloropropene is the sum of cis- and trans-1,3-dichloropropene. 10 TCDD equivalents: TCDD equivalents shall mean the sum of the concentrations of 2,3,7,8-CDDs and 2,3,7,8-CDFs multiplied by their respective toxicity equivalency factor (see Attachment A).

V. WHOLE EFFLUENT TOXICITY TESTING REQUIREMENTS A. Acute Whole Effluent Toxicity 1. Monitoring Frequency The Discharger shall conduct acute toxicity tests on 24-hour composite effluent samples (Table E-4). Once each calendar year, at a different time of year from the previous years, the Discharger shall split a 24-hour composite effluent sample and concurrently conduct toxicity tests using a fish and an invertebrate species. The Discharger shall then continue to conduct routine quarterly toxicity testing using the single, most sensitive species.

CA0110604 COLLECTION SYSTEM & OUTFALLS Acute toxicity test samples shall be collected at the designated NPDES sampling station for the effluent. In order to better relate toxicity to other effluent characteristics, it is recommended that at least twice per year the Discharger process a split toxicity sample for analysis of all other monitored parameters specified by the effluent monitoring program. 2. Marine and Estuarine Species and Test Methods Species and short-term test methods for estimating the acute toxicity of NPDES effluents are generally found in the fifth edition of Methods for Measuring the Acute Toxicity of Effluents and Receiving Waters to Freshwater and Marine Organisms (EPA/821/R-02/012, 2002; Table IA, 40 CFR § 136). For this Order/Permit, the Discharger shall conduct 96-hour static renewal toxicity tests with topsmelt, Atherinops affinis, representing a vertebrate species (Test Method 2006.0), and the mysid, Americamysis bahia, representing an invertebrate species (Test Method 2007.0). If laboratory-held cultures of the topsmelt, Atherinops affinis, are not available for testing, then the Discharger shall conduct a 96-hour static renewal toxicity test with the inland silverside, Menidia beryllina (Test Method 2006.0). 3. Quality Assurance a. Quality assurance measures, instructions, and other recommendations and requirements are found in the test methods manuals previously referenced. Additional requirements are specified, below. b. For Discharge Point 001, an acute dilution allowance is authorized such that the critical acute instream waste concentration (IWC) is set at a percent effluent value lower than 100% effluent. The acute IWC for Discharge Point 001 is 5.56% effluent. c. Effluent dilution water and control water should be prepared and used as specified in the test methods manual for the test species. If the dilution water is different from test organism culture water, then a second control using culture water shall also be used. If the use of artificial sea salts is considered provisional in the test method, then artificial sea salts shall not be used to increase the salinity of the effluent sample prior to toxicity testing without written approval by the permitting authority. d. If organisms are not cultured in-house, then concurrent testing with a reference toxicant shall be conducted. If organisms are cultured in-house, then monthly reference toxicant testing is sufficient. Reference toxicant tests and effluent toxicity tests shall be conducted using the same test conditions (e.g., same test duration, etc.). e. If the effluent toxicity test during the reporting period for the month does not meet the Test Acceptability Criteria JAC) in the WET method (EPA/600/R- 95/136, 1995), then the permittee shall resample and retest within 14 days.

If the discharged effluent is disinfected using chlorine, then total chlorine residual shall not be removed from the effluent sample prior to toxicity testing. B. Chronic Whole Effluent Toxicity 1. Monitoring Frequency The Discharger shall conduct chronic toxicity tests on 24-hour composite effluent samples (Table E-4). Once each calendar year, at a different time of year from the previous years, the Discharger shall split a 24-hour composite effluent sample and concurrently conduct three toxicity tests using a fish, an invertebrate, and an algal species. The Discharger shall then continue to conduct routine monthly toxicity testing using the single, most sensitive species. Chronic toxicity test samples shall be collected at the designated NPDES sampling station for the effluent. In order to better relate toxicity to other effluent characteristics, it is recommended that at least twice per year the Discharger process a split toxicity sample for analysis of all other monitored parameters specified by the effluent monitoring program. 2. Marine and Estuarine Species and Test Methods Species and short-term test methods for estimating the chronic toxicity of NPDES effluents are found in the first edition of Short-term Methods for Estimating the Chronic Toxicity of Effluents and Receiving Waters to West Coast Marine and Estuarine Organisms (EPA/600/R-95/136, 1995) and applicable water quality standards; also see 40 CFR § 122.410)(4) and 122.44(d)(1)(iv), and 40 CFR § 122.21(j)(5)(viii) for POTWs. The Discharger shall conduct a static renewal toxicity test with the topsmelt, Atherinops affinis (Larval Survival and Growth Test Method 1006.0); a static non- renewal toxicity test with the giant kelp, Macrocystis pyrifera (Germination and Growth Test Method 1009.0); and a toxicity test with one of the following invertebrate species: Static non-renewal toxicity test with the red abalone, Haliotis rufescens (Larval Shell Development Test Method); Static non-renewal toxicity test with the purple sea urchin, Strongylocentrotus purpuratus, or the sand dollar, Dendraster excentricus (Fertilization Test Method 1008.0). If laboratory-held cultures of the topsmelt, Atherinops affinis, are not available for testing, then the Discharger shall conduct a static renewal toxicity test with the inland silverside, Menidia beryllina (Larval Survival and Growth Test Method 1006.0) in the third edition of Short-term Methods for Estimating the Chronic Toxicity of Effluents and Receiving Waters to Marine and Estuarine Organisms (EPA/821/R-02/014, 2002).

Quality assurance measures, instructions, and other recommendations and requirements are found in the chronic test methods manuals previously referenced. Additional requirements are specified, below. b. For Discharge Point 001 , a chronic dilution allowance is authorized such that the critical chronic instream waste concentration (IWC) is set at a percent effluent value lower than 100% effluent. The chronic IWC for Discharge Point 001 is 0.556% effluent. For Discharge Point 002, a chronic dilution allowance is authorized such that the critical chronic instream waste concentration (IWC) is set at a percent effluent value lower than 100% effluent. The chronic IWC for Discharge Point 002 is 2.78% effluent. c. Effluent dilution water and control water should be prepared and used as specified in the test methods manual Short-term Methods for Estimating the Chronic Toxicity of Effluents and Receiving Waters to West Coast Marine and Estuarine Organisms (EPA/600/R-95/136, 1995) and/or Short- term Methods for Estimating the Chronic Toxicity of Effluents and Receiving Waters to Marine and Estuarine Organisms (EPA/821/R- 02/014, 2002). If the dilution water is different from test organism culture water, then a second control using culture water shall also be used. If the use of artificial sea salts is considered provisional in the test method, then artificial sea salts shall not be used to increase the salinity of the effluent sample prior to toxicity testing without written approval by the permitting authority. d. If organisms are not cultured in-house, then concurrent testing with a reference toxicant shall be conducted. If organisms are cultured in-house, then monthly reference toxicant testing is sufficient. Reference toxicant tests and effluent toxicity tests shall be conducted using the same test conditions (e.g., same test duration, etc.). e. If the effluent toxicity test during the reporting period for the month does not meet the Test Acceptability Criteria (TAC) in the WET method (EPA/600/R- 95/136, 1995), then the permittee shall resample and retest within 14 days. The results of this retest shall only replace that effluent toxicity test that did not meet TAC during the reporting period for the month. f. If the discharged effluent is disinfected using chlorine, then total chlorine residual shall not be removed from the effluent sample prior to toxicity testing. g. pH drift during the toxicity test may contribute to artifactual toxicity when pH- dependent toxicants (e.g., ammonia, metals) are present in an effluent. To determine whether or not pH drift during the toxicity test is contributing to artifactual toxicity, the Discharger shall conduct three sets of parallel toxicity tests, in which the pH of one treatment is controlled at the pH of the effluent and the pH of the other treatment is not controlled, as described in Section 13.3.6 of the test methods manual, Short-term Methods for Estimating the ATTACHMENT E- MONITORING AND REPORTING PROGRAM E-43 ORANGE COUNTY SANITATION DISTRICT ORDER NO.

Toxicity is confirmed to be artifactual and due to pH drift when no toxicity above the chronic WET permit limit is observed in the treatments controlled at the pH of the effluent. If toxicity is confirmed to be artifactual and due to pH drift, then, following written approval by the permitting authority, the Discharger may use the procedures outlined in Section 13.3.6 of the test methods manual to control sample pH during the toxicity test. C. Analysis and Reporting of Acute and Chronic Toxicity Monitoring Results 1. For Discharge Point 001 , a full toxicity laboratory report for all acute and chronic toxicity testing shall be submitted as an attachment to the Self-Monitoring Report (SMR) for the month in which the toxicity tests are initiated.

RECEIVING WATER REGIONAL MONITORING REQUIREMENTS Discharger participation in regional monitoring programs is a required condition of this Order/Permit. The Discharger shall participate in regional monitoring activities coordinated by the Southern California Coastal Water Research Project (SCCWRP), County of Orange Health Care Agency (HCA), the Southern California Coastal Ocean Observation System (SCCOOS), and other appropriate agencies once approved by the Santa Ana Water Board and USEPA. The regional monitoring programs which must be conducted under this Order/Permit include: A. Southern California Bight Regional Monitoring Program The Discharger shall continue to participate in Southern California Bight Regional Monitoring Program studies, including water quality, benthic infauna, sediment chemistry, fish communities, fish predator risk, and ocean acidification, which are coordinated through the Southern California Coastal Water Research Project (SCCWRP) (e.g., the 1994 Southern California Bight Pilot Project, Bight'98, Bight'03, Bight'08, Bight'13, and Bight'18). Participation in the Southern California Bight Regional Monitoring Program shall include aspects of the program relevant to understanding regional trends and answering regional questions related to public health (i.e., bacterial contamination), water quality, sediment geochemistry, biological communities, and seafood safety (e.g., fish tissue contamination) in the receiving waters environment. For sediment chemistry and benthic infauna communities, this level of effort shall be similar to the 35 one-off (i.e., 1/5-year) summer samples. For trawls, participation shall be equivalent to the 8 annual summer samples. In both cases (i.e., the benthic and trawl programs), 22 quarterly/annual benthic stations and 6 semi-annual trawl stations identified in the monitoring program should continue to be sampled, even during regional monitoring program events, to assess compliance and trends near the discharge. The Discharger shall complete collection, analysis, and reporting of samples in accordance with the schedules established by the next Bight regional program ATTACHMENT E- MONITORING AND REPORTING PROGRAM E-57 ORANGE COUNTY SANITATION DISTRICT ORDER NO.

Previous participation included method development, research, and monitoring activities involving microbiology, water quality data, marine sediments, fish/macrobenthic assemblages, fish tissue contamination, and harmful algal blooms related to point and nonpoint discharges to the marine environment. Levels of participation and areas of study are dependent upon the final study plans established by Bight regional program development committees, but will be equivalent to that provided by the Discharger in previous regional surveys conducted in 1994, 1998, 2003, 2008, 2013, and 2018. For Bight'18, this involved: 1. Participation in regional microbiological studies testing rapid methods and developing rapid methods for detection of fecal indicator bacteria in beach sands at 2 beach stations. 2. Collection and analysis of water quality samples for analyzing the relationship between nutrients discharged through POTW outfalls, upwelling, and harmful algal blooms. Note that this study was deferred to Bight'23 due to logistical sample deployment issues. 3. Collection and analysis of water quality samples for ocean acidification and hypoxia (OAH), including bongo net towing to collect pteropods, at 4 bongo net tow stations. 4. Collection and analysis of sediment grab samples for geochemistry and benthic infauna at 44 benthic stations . 5. Collection and analyses of fish and macroinvertebrate community structure at 21 trawl stations. 6. Collection and analysis of fish tissue from approximately two zones or the equivalent of 40 tissue samples for chemical contaminants (organics and metals), and analysis of selected biomarkers at a subset of these stations. B. Southern California Bight Regional Water Quality Program The Southern California Bight Regional Water Quality Program (SCBRWQP; previously known as the Central Bight Water Quality Cooperative Program or the Central Bight Regional Water Quality Monitoring Program) is a coordinated quarterly receiving water quality monitoring program conducted by OC San, the County Sanitation Districts of Los Angeles, the City of Los Angeles, the City of San Diego, and the City of Oxnard. 1.

An automated data quality control system shall be established for telemetered data (i.e., real-time, online ocean acidification data) based on the Integrated Ocean Observation System (IOOS) protocols. X. STRATEGIC PROCESS STUDIES The Discharger shall conduct Strategic Process Studies (SPS) to document the effectiveness of its source control and wastewater treatment operations in protecting the coastal ocean. SPS are designed to address unanswered questions raised by the Core monitoring program results and/or focus on issues of interest to the Discharger, the Santa Ana Water Board, and/or USEPA. SPS shall be proposed and be approved by the Santa Ana Water Board and USEPA to ensure appropriate focus and level of effort. Five studies below must be conducted under this Order/Permit using previously approved work plans as these studies have been approved during the term of the 2012 Order/Permit and are not yet completed: A. ROMS-BEC Ocean Outfall Modeling: The Discharger works with SCCWRP and their collaborators to model and assess the spatial and temporal extent of its discharged effluent before and after the implementation of the GWRS Final Expansion. B. Microplastics Characterization: This SPS characterizes the quantity and types of microplastics throughout the Discharger's treatment system. This study will also develop methods and analyses to help inform the transport, fate and impacts of microplastics through the Discharger's wastewater treatment process to the receiving environment. C. In-vitro Cell Bioassay Monitoring Assessment: This study will provide a preliminary assessment of contaminants of emerging concern (CEC) in the receiving water using in- vitro cell bioassay techniques. Cell bioassays can be used as a screening tool to evaluate potential impacts resulting from changes in the effluent and receiving environment water quality associated with the GWRS Final Expansion.

Sediment Linear Alkylbenzenes: Linear Alkylbenzenes (LABs) were previously used to investigate whether other contaminants present in the sediment were associated with the effluent discharge. This SPS will provide updated data within the Discharger's monitoring area for evaluating future changes due to GWRS Final Expansion. E. Meiofauna Baseline: The Discharger will investigate the impacts of increased RO concentrate flows from the GWRS Final Expansion on marine biota in the receiving water using meiofauna (animals ranging from 63 to 500 dam in size) which are known to be more sensitive to anthropogenic impacts than macrofauna. This SPS will characterize the meiofauna communities in the receiving environment and evaluate the suitability of using meiofauna for a before-after control-impact study of the GWRS Final Expansion. XI. OTHER MONITORING REQUIREMENTS A. Contaminants of Emerging Concern (CEC) Monitoring Study The Discharger shall continue to investigate CEC in the discharge and/or receiving waters, following its approved CEC study workplan. Within six (6) months of the effective date of this Order/Permit, the Discharger shall submit for Executive Officer/Director approval an updated CEC study workplan and submit the special study final report with the application for permit reissuance. The workplan shall include, but is not limited to: 1. Updates of CEC identification for discharge monitoring (e.g., CEC concentrations and mass loadings, sample type, minimum sampling frequency, and analytical test method considering sensitivity, accuracy, availability, and cost). The parameters in Table E-15 may be re-evaluated and modified by the Executive officer/Director. The workplan may also propose surrogate or indicator CEC that may better characterized discharged CEC.

Sample results greater than or equal to the reported ML shall be reported as measured by the laboratory (i.e., the measured chemical concentration in the sample). b. Sample results less than the reported ML, but greater than or equal to the laboratory's MDL, shall be reported as "Detected, but Not Quantified," or DNQ. The estimated chemical concentration of the sample shall also be reported. For the purposes of data collection, the laboratory shall write the estimated chemical concentration next to DNQ. The laboratory may, if such information is available, include numerical estimates of the data quality for the reported result. Numerical estimates of data quality may be percent accuracy (± a percentage of the reported value), numerical ranges (low to high), or any other means considered appropriate by the laboratory. c. Sample results less than the laboratory's MDL shall be reported as "Not Detected," or ND. d. Dischargers are to instruct laboratories to establish calibration standards so that the ML value (or its equivalent if there is differential treatment of samples relative to calibration standards) is the lowest calibration standard. At no time is the Discharger to use analytical data derived from extrapolation beyond the lowest point of the calibration curve. 5. Compliance Determination. Compliance with effluent limitations for reportable pollutants shall be determined using sample reporting protocols defined above and Attachment A of this Order/Permit. For purposes of reporting and administrative enforcement by the Santa Ana Water Board, State Water Board, and USEPA, the Discharger shall be deemed out of compliance with effluent limitations if the concentration of the reportable pollutant in the monitoring sample is greater than the corresponding effluent limitation and greater than or equal to the reported Minimum Level (ML). 6. Multiple Sample Data. When determining compliance with a measure of central tendency (arithmetic mean, geometric mean, median, etc.) of multiple sample analyses and the data set contains one or more reported determinations of DNQ or ND, the Discharger shall compute the median in place of the arithmetic mean in accordance with the following procedure: a. The data set shall be ranked from low to high, ranking the reported ND determinations lowest, DNQ determinations next, followed by quantified values (if any). b. The median value of the data set shall be determined. If the data set has an odd number of data points, then the median is the middle value. If the data set has an even number of data points, then the median is the average of the two values around the middle unless one or both of the points are ND or DNQ, in which case the median value shall be the lower of the two data points where DNQ is lower than a value and ND is lower than DNQ. 7.

B. The Facility discharges wastewater to the Pacific Ocean, a water of the United States. The Discharger was previously regulated by Order No. R8-2012-0035 and National Pollutant Discharge Elimination System (NPDES) Permit No. CA0110604 adopted on June 15, 2012 and expired on July 19, 2017. The Discharger filed a report of waste discharge and submitted an application for reissuance of its waste discharge requirements (WDRs) and NPDES permit on January 3, 2017, and the previous order was administratively extended by operation of law. Attachment B provides a map of the area around the Facility. Attachment C provides a flow schematic of the Facility. C. Regulations at 40 CFR § 122.46 limit the duration of NPDES permits to a fixed term not to exceed five years. Accordingly, Table 3 of this Order/Permit limits the duration of the discharge authorization. However, pursuant to California Code of Regulations, title 23, section 2235.4, the terms and conditions of an expired permit are automatically continued pending reissuance of the permit if the Discharger complies with all federal NPDES requirements for continuation of expired permits. (See also 40 CFR § 122.6(d)). II. FACILITY DESCRIPTION A. Description of Wastewater and Biosolids Treatment and Controls The Discharger's POTW serves approximately 480 square miles of central and northern Orange County, California. Currently, the POTW consists of approximately ATTACHMENT F- FACT SHEET F-5 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS 388 miles of trunk sewer systems and force mains, 15 offsite pump stations, two wastewater treatment plants, and three outfalls. In addition to the domestic, commercial, and industrial wastewater received from this service area, through interagency agreements, influent flows are contributed by the Santa Ana Watershed Project Authority (SAWPA) including Stringfellow Superfund Site (EPA ID #CAT080012826), Irvine Ranch Water District, and the Sanitation District of Los Angeles County. During dry weather conditions, the Discharger also accepts small volumes (average daily amount up to 10 MGD) of dry weather urban runoff from within the service area. During 2018-2019, the Discharger's wastewater treatment plants received and processed influent volumes averaging 191 MGD. Raw wastewater entering either Reclamation Plant No. 1 or Treatment Plant No. 2 passes through metering and diversion structures and continues to headworks facilities for preliminary treatment. Note that influent flow from SAWPA is tributary to Reclamation Plant No. 1 via the Santa Ana River Interceptor (SARI). Because the California Department of Health does not permit SARI flow for the Groundwater Replenishment System (GWRS) reclamation, all SARI flow is diverted to Treatment Plant No. 2 through the Interplant Interceptor for treatment and ocean discharge. Preliminary treatment includes grit and screenings removal. Caustic soda shock, ferrous chloride, calcium nitrate, magnesium hydroxide and polymer can be added to reduce corrosion and odor and provide enhanced primary treatment. The wastewater then receives primary treatment in primary sedimentation facilities. The primary effluent is routed to either trickling filters or activated sludge facilities for secondary treatment. Secondary treated trickling filter and activated sludge effluents from Reclamation Plant No. 1 are delivered to the Orange County Water District (OCWD) for further tertiary treatment and reclamation. The OC San discharges secondary treated effluent from Treatment Plant No. 2 through Discharge Point 001 (primary 120" ocean outfall) to the Pacific Ocean, a water of the United States, except under emergency circumstances. In 2023, when the Final Expansion of the GWRS is complete, Treatment Plant No. 2 effluents will also be reclaimed at the GWRS. SARI flow will be separated from other domestic wastewater at Plant No. 2, where it will be secondary treated before being discharged to the ocean. The use of continuous disinfection prior to discharge through Discharge Point No. 001 (120" outfall) has been ceased since May 2015. Effluent disinfection with chlorine bleach followed by de- chlorination with sodium bisulfite occurs at the other two discharge points 002 and 003. Dewatered biosolids are shipped offsite to land application, composting, thermal conversion, or landfill facilities. Attachment B provides a map of the area around the treatment facilities. Attachment C provides flow schematics of the full secondary treatment facilities. OCWD receives two streams of OC San secondary treated wastewater, one for the Green Acres Project (GAP, out of service in winter) and the second one for the GWRS. Both GAP and GWRS are major regional wastewater reclamation projects owned and operated by OCWD and located adjacent to Reclamation Plant No. 1. Advanced treatment for the GWRS includes microfiltration, reverse osmosis, and advance oxidation (ultraviolet/peroxide). The Discharger provides approximately 100 % of secondary treated effluent from Plant No.1 to GWRS for advanced treatment and ATTACHMENT F- FACT SHEET F-6 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS reuse. In Fiscal Year 2018-19, the average effluent flow to OCWD was 117 MGD. The GWRS Final Expansion has been under construction since November 2019, which supports the Discharger's strategic goal of maximizing water recycling up to 175 MGD at both plants, and OCWD's goal to produce up to 130 MGD of purified recycled water by 2023. GAP can divert up to 7.5 MGD of the Discharger's secondary treated wastewater for tertiary treatment, disinfection, and reuse for landscaped irrigation and industrial uses. In Fiscal Year 2018-19 summer months, average flow to GAP was 4 MGD. The GAP and part of the GWRS generates waste streams (e.g., microfiltration backwash, sump waste, and lime waste) are recycled back into the OC San's primary treatment facility, except for RO reject (or concentrate) which are returned to OC San, blended with other secondary treated waste streams and discharged via ocean outfalls. In 2019, average daily total influent flow to both plants was 192 MGD, but because of water recycling efforts, the average daily ocean discharge was 100 MGD. Based on 2017 OCSD Facilities Master Plan, the average daily influent flow projected for 2025 is 188-206 MGD during the dry weather season and 478-523 MGD during the peak wet weather season. Note that lower and upper bound flows are based on the current trend and a conservative approach, respectively. The projected 2025 average daily ocean discharges are 55-73 MGD for dry weather and 344-389 MGD for peak wet weather, of which RO concentrate flow is 23 MGD. B. Discharge Points and Receiving Waters Secondary treated effluents from Plant No. 1 and 2 are discharged to the Pacific Ocean through the Discharger's ocean outfall system. There are two booster pump stations (i.e., the Ocean Outfall Booster Station (OOBS) and the Effluent Pump Station Annex (EPSA)) that pump secondary effluent to two ocean outfalls: Discharge Point 001 via the 120" pipelines and Discharge Point 002 via the 78" pipelines. In addition to these two ocean outfalls, there are two overflow weirs at Plant No. 2 that discharge into the Santa Ana River. 1. Discharge Point 001 (120" outfall). Discharge Point 001 (120" outfall) is the primary discharge point (activated ocean outfall, with a rated capacity of 480 MGD) to the Pacific Ocean terminating in a diffuser with 503 ports, at a depth of about 197 feet (60 meters) below mean sea level. Discharge Point 001 (120" outfall) is approximately 4.5 miles (3.9 nautical miles) offshore in federal waters as the territorial waters of the State end 3 nautical miles from shore. The Ocean Plan (Appendix 1, Ocean Waters) states, "If a discharge outside the territorial waters of the State could affect the quality of the waters of the State, the discharge may be regulated to assure no violation of the Ocean Plan will occur in ocean waters." This Order/Permit contains discharge prohibitions, effluent limitations, receiving water limitations, and other provisions to ensure that discharges from Discharge Point 001 do not affect State waters. The Ocean Plan minimum probable initial dilution (Dm = 180) for this outfall is 181:1. 2. Discharge Point 002 (78" outfall). Discharge Point 002 (78" outfall) is an emergency discharge point (deactivated ocean outfall, with a rated capacity of 230 ATTACHMENT F- FACT SHEET F-7 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS MGD) to the Pacific Ocean terminating in a 130 ports diffuser, approximately 1.5 mile offshore from the mouth of the Santa Ana River, at a depth of about 65 feet (20 meters) below mean sea level. This outfall is used only during an emergency or planned essential maintenance or capital improvement projects to assure efficient operation of the 120" outfall under 40 CFR § 122.41(m)(2) since the 120" outfall was put into service in 1971 . The Ocean Plan minimum probable initial dilution (Dm = 36) for this outfall is 37:1. 3. Discharge Point 003 (Santa Ana River Overflow Weirs). Discharge Point 003 (i.e., the Santa Ana River Overflow Weirs) is comprised of two extreme emergency discharge points (overflow) to the tidal prism in the Santa Ana River, which eventually flows to the Pacific Ocean. One of the overflow points is located at the termination structure upstream of the EPSA facility and other one is at the OOBS facility. The structure consists of a 50' long overflow weir with two 72" pipes. The total capacity is approximately 605 MGD (i.e., 130 MGD from EPSA and 475 MGD from OOBS), but the actual capacity depends on the water level at the river. This outfall has never discharged over the past 10 years; however, it remains available for extreme emergency uses (e.g., tsunami, earthquake, flood, and acts of war or terrorism). Table F-2.

ND: Not detected D. Compliance Summary Completion of Secondary Treatment Projects Since the construction of the facilities that was required to achieve secondary treatment standards were not completed at the time the previous permit was issued, OC San entered into a consent decree mandating OC San to meet secondary treatment limits by December 31, 2012. After extensive process improvement and Capital Improvement Projects (CIP) including completion of the following: • Trickling filter project at Reclamation Plant No. 1, completed in Spring 2006; • Secondary treatment rehabilitation project at Treatment Plant No. 2, completed in Spring 2008; • New trickling filters and solid contact basins at Treatment Plant No. 2, completed in Summer 2011. The project added 60 MGD of secondary treatment capacity; and • New activated sludge system at Reclamation Plant No. 1, completed in Fall 2012. The project added 60 MGD of secondary treatment capacity. The Discharger has officially declared the POTW at full secondary treatment on December 28, 2012 and continue operating at and meeting full secondary requirements. Cessation of Continuous Disinfection Practices at Discharge Point 001 (120" outfall The disinfection program initiated in 2002 was based on using sodium hypochlorite (bleach) for disinfection and sodium bisulfite for dechlorination. Beginning in 2006, the Discharger started to note negative changes in the structure and health of benthic communities within the zone of initial dilution (ZID) around the diffuser to the 120-inch ATTACHMENT F- FACT SHEET F-11 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS outfall (the primary discharge point). To determine the causes of these changes to the marine environment, the Discharger conducted detailed studies divided into two phases: Phase 1 (2009-2010) for an analysis of historical data to identify any potential causes and Phase 11 (2011-2012) for investigation of operational changes and process improvements that occurred at the treatment facilities and the facility's dry-weather urban runoff diversion program. Based on the results of these investigations, the discharge of chlorinated effluent prior to 2012 resulted in a decline in benthic communities near the ZID. The benthic environment has been improved since 2012 due to reduction of the use of chlorine after achieving full secondary treatment. After long-term beach water quality studies and oceanographic data evaluation by an Independent Advisory Panel (IAP) of experts hosted by the National Water Research Institute (NWRI), it was concluded that continuing to chlorinate full secondary treated effluent provides little to no public health benefit to local beaches. The Discharger has also achieved continuous compliance with the secondary treatment requirements of the Clean Water Act. On March 17, 2015, based on the observations and recommendations of the IAP and with public support, OC San received approval from the Santa Ana Regional Water Quality Control Board and USEPA to cease disinfection at Discharge Point 001 (120" outfall). OC San has ceased continuous chlorination/dechlori nation since May 2015. The disinfection system would remain available for later use, if determined necessary. Use of disinfection remains at the other two discharge points (Discharge Points 002 and 003) to protect human health. Planned 6-Week Diversion to Discharge Point 002 (78" outfall) From September 11, 2012 through October 4, 2012, the Discharger temporarily diverted disinfected effluent from Discharge Point 001 (120" outfall) to Discharge Point 002 (78" outfall) as part of an infrastructure rehabilitation project (refer to as Capital Improvement Project J-112) to inspect, assess, and rehabilitate the Outfall Land Section and Ocean Outfall Booster Pump Station Piping. To minimize impacts to public health, the treated wastewater received enhanced disinfection so that state bacterial water contact standards were met prior to discharge and subsequent dilution. The Discharger conducted the J-112 environmental monitoring program including modeling to track the discharged plume, measure the effectiveness of the enhanced disinfection program, and determine environmental impacts to the receiving water during the diversion to the nearshore outfall. The lessons learned report and a more comprehensive report (i.e., 2012 OCSD Outfall Diversion Summary Report) were submitted to the Santa Ana Water Board and USEPA on March 25, 2014, which summarize the sampling methodology during the diversion and provide recommendations for improving monitoring during any future diversions to Discharge Point 002 (78" outfall). Unintentional Bypass of primary effluent from Plant No. 2 to Discharge Point 001 (120" outfall) The unintentional bypass of primary effluent into Discharge Point 001 (120" outfall) occurred on July 5, 2020 from 4:28 am to 5:02 am, a duration of 34 minutes, due to a power loss after an Edison transformer failed. The power loss affected equipment ATTACHMENT F- FACT SHEET F-12 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS throughout Treatment Plant No. 2 including the trickling filter influent pumps. The trickling filter weir overflowed with primary treated wastewater, approximately 0.94 million gallons of which discharged directly to the 120" outfall. Another unanticipated bypass of primary effluent into the 120" outfall occurred at the same location due to failure of two of three lead pumps serving the trickling filters pump station (TFPS) during a wet weather event on December 28, 2020 at 7:09 pm for approximately 9 minutes. The estimated flow over the TFPS weir is total 78,500 gallons. After discovering each incident, the Discharger notified the Santa Ana Water Board and USEPA and investigated the incident to determine the cause and duration of the incident, the volume discharged, and to evaluate and implement appropriate corrective actions to prevent this incident from reoccurring. As part of corrective actions, the TFPS lead pumps were disassembled, and their internal fans replaced. As a key sustainable action, OC San is currently in construction installing an upgraded power monitoring/power management control system to improve the power system response speed to prevent short term power loss event that can lock out equipment. This project is scheduled to be complete by 2023. E. Planned Changes GWRS Final Expansion Protect The GWRS is a regional water reclamation program that was initiated jointly by OC San and OCWD and began operation in January 2008. The GWRS Initial Expansion was completed in 2015, which allowed OCWD to take up to 135 MGD of secondary effluent from Plant No. 1 to produce 100 MGD of GWRS product water. Currently, the Discharger sends approximately 100% of secondary effluent from Plant No. 1 to GWRS to provide a drought-proof water supply for Orange County. Also, it delivers up to 4 MGD of secondary effluent from Plant No. 1 to GAP during the summer months to provide recycled water for landscaped irrigation and industrial uses. The layout of the OCWD facilities has been designed to provide GWRS with an ultimate production capacity of 130 MGD. The GWRS ultimate production capacity of 130 MGD is referred to as the GWRS Final Expansion project. Based on the SP-173 Effluent Reuse Study for the evaluation of reclamation of Plant No. 2 effluent, the following projects are identified by the implementation plan for the GWRS Final Expansion and anticipated to be completed by 2023. • Modify Plant 2 Headworks Facility to create a reclaimable and non-reclaimable treatment train. Reclaimable flows will go through existing preliminary, primary, and secondary (trickling filter solids contact) treatment before being pumped to GWRS. • Build a Plant 2 effluent pump station that will convey approximately 50-85 MGD of secondary effluent from Plant No. 2 trickling filter solids contact process to the GWRS Facility. ATTACHMENT F- FACT SHEET F-13 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS • Build a 6 MG equalization storage tank at Plant No. 2 to store secondary effluent during peak day flows and be returned to the system during low flow periods to maintain a constant flow to the GWRS. • Relocate the existing plant water pump station to a location more suitable for receiving the trickling filter solids contact treatment processes. After the GWRS Final Expansion, the activated sludge treatment process will treat only SARI and side-stream flows. • Convert the unused 66-inch gravity reinforced concrete pipeline into a pressure pipeline using a trenchless pipe repair method, to convey the effluent pump station discharge. This expansion would require a total flow from OC San plants of approximately 175 MGD to produce 130 MGD of indirect potable reuse water. The Final Expansion of the GWRS will enable the Discharger to recycle the majority of the wastewater generated in its service area and treated at its two wastewater treatment plants. Organic Waste Co-Digestion Project Construction and operation of an organic waste co-digestion facility is anticipated to be completed in 2022. An organic waste receiving facility will be constructed to receive, store, and feed approximately 150 tons of pre-processed food waste slurry to the digester complex at Plant No. 2 (by Digester M) to generate additional digester gas per recommendations of the Biosolids Master Plan. This facility will be replaced with a permanent receiving station following completion of a proposed program to replace existing digesters at Plant No. 2. Food waste will be fed into OC San's digesters, creating more gas and electricity, while producing a few extra truckloads of solids per week. III.

California Environmental Quality Act (CEQA) Under Water Code section 13389, this action to adopt an NPDES permit is exempt from the provisions of Chapter 3 of CEQA, (commencing with section 21100) of Division 13 of the Public Resources Code. C. State and Federal Laws, Regulations, Policies, and Plans 1. Water Quality Control Plan. The Santa Ana Regional Water Quality Control Board adopted a Water Quality Control Plan for the Santa Ana River Basin (hereinafter Basin Plan) in 1995, that designates beneficial uses, establishes water quality objectives, and contains implementation programs and policies to achieve those objectives for the Offshore Zone and Nearshore Zone of the Pacific Ocean and the tidal prism of the Santa Ana River. In addition, the Basin Plan implements State Water Resources Control Board (State Water Board) Resolution No. 88-63 which established State policy that all waters, with certain exceptions, should be considered suitable or potentially suitable for municipal or domestic supply. Requirements in this Order/Permit implement the Basin Plan. Basin Plan beneficial uses applicable to the Pacific Ocean and/or the Santa Ana River tidal prism are as follows: Table F-5. Basin Plan Beneficial Uses Discharge Receiving Water Beneficial Use(s) Point Name Pacific Ocean, Offshore Zone: Industrial service supply; navigation; 001 water contact recreation; non-contact water (120" outfall) Beyond the limit of State waters recreation; commercial and sportfishing; wildlife habitat; rare, threatened, or endangered species; spawning, reproduction, and development; and 002 Pacific Ocean, marine habitat. (78" outfall) Offshore Zone Nearshore Zone: Industrial service supply; navigation; water contact recreation; non-contact water recreation; commercial and sportfishing; wildlife 003 habitat; rare, threatened, or endangered species; Santa Ana River spawning, reproduction, and development; marine (Santa Ana Tidal Prism, habitat; and shellfish harvesting. River overflow Reach 1 Santa Ana River, Reach 1: Water contact recreation weirs) (access prohibited); non-contact water recreation; warm freshwater habitat; and wildlife habitat. 2. California Ocean Plan. The State Water Board adopted the Water Quality Control Plan for Ocean Waters of California, California Ocean Plan (hereinafter Ocean Plan) in 1972 and amended it in 1978, 1983, 1988, 1990, 1997, 2000, 2005, 2009, 2012, 2015, 2018, and 2019. The Ocean Plan is applicable, in its entirety, to point source discharges to the ocean. The Ocean Plan identifies ATTACHMENT F- FACT SHEET F-15 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS beneficial uses of ocean waters of the state to be protected as summarized below: Table F-6. Ocean Plan Beneficial Uses Discharge Receiving Beneficial Uses Point Water Industrial water supply; water contact and non-contact recreation, including aesthetic enjoyment; navigation; 001 and 002 Pacific Ocean commercial and sport fishing; mariculture; preservation and enhancement of designated Areas of Special Biological Significance (ASBS); rare and endangered species; marine habitat; fish spawning and shellfish harvesting In order to protect the beneficial uses, the Ocean Plan establishes water quality objectives and a program of implementation. Requirements of this Order/Permit implement the Ocean Plan. 3. California Thermal Plan. The State Water Board adopted the Water Quality Control Plan for Control of Temperature in the Coastal and Interstate Waters and Enclosed Bays and Estuaries of California (hereinafter Thermal Plan) on January 7, 1971, and amended this plan on September 18, 1975. This plan contains temperature objectives for coastal and inland surface waters. Requirements of this Order/Permit implement the Thermal Plan. 4. Antidegradation Policy. Federal regulation 40 CFR § 131.12 requires that the state water quality standards include an antidegradation policy consistent with the federal policy. The State Water Board established California's antidegradation policy in State Water Board Resolution 68-16 ("Statement of Policy with Respect to Maintaining High Quality of Waters in California"). Resolution 68-16 is deemed to incorporate the federal antidegradation policy where the federal policy applies under federal law. Resolution 68-16 requires that existing water quality be maintained unless degradation is justified based on specific findings. The Santa Ana Regional Water Quality Control Board's Basin Plan implements, and incorporates by reference, both the state and federal antidegradation policies. The permitted discharge must be consistent with the antidegradation provision of section 131.12 and State Water Board Resolution 68-16. 5. Anti-Backsliding Requirements. Sections 402(o) and 303(d)(4) of the CWA and federal regulations at 40 CFR § 122.44(I) restrict backsliding in NPDES permits. These anti-backsliding provisions require that effluent limitations in a reissued Order/Permit must be as stringent as those in the previous Order/Permit, with some exceptions in which limitations may be relaxed. 6. Alaska Rule. USEPA has revised its regulation that specifies when new and revised State and tribal water quality standards become effective for CWA purposes. (40 CFR § 131.21; 65 Fed. Reg. 24641 (April 27, 2000).) Under the revised regulation (also known as the Alaska Rule), new and revised standards ATTACHMENT F- FACT SHEET F-16 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS submitted to USEPA after May 30, 2000 must be approved by USEPA before being used for CWA purposes. The final rule also provides that standards already in effect and submitted to USEPA by May 30, 2000, may be used for CWA purposes, whether or not approved by USEPA. 7. Section 403(c) of the Clean Water Act (CWA): Discharges to marine waters are subject to Section 403 of the CWA, which sets forth criteria to prevent unreasonable degradation of the marine environment and authorized imposition of any additional effluent limits necessary to protect the marine environment. Pursuant to 40 CFR § 125.122, unreasonable degradation of the marine environment is evaluated based on ten factors or based on the application of a state's water quality standards. Specifically, 40 CFR § 125.122(b) states that discharges in compliance with State water quality standards "shall be presumed not to cause unreasonable degradation of the marine environment, for any specific pollutants or conditions specified in the variance or the standard." USEPA and the Santa Ana Water Board are applying the Basin Plan and the Ocean Plan as specified in section III.C.1 and 2 of this Fact Sheet, except for evaluating acute/chronic toxicity for Discharge Points 001 and 002 using the TST statistical approach. USEPA has reviewed the previous studies to examine the comparison of toxicity test results using the TST and NOEC statistical approaches and has determined that use of the TST statistical approach is consistent with the Ocean Plan and CWA § 403(c) in that it provides protection of the designated beneficial uses of ocean waters. TST statistical approach is also used in other NPDES permits for large publicly owned treatment works, including City of Los Angeles. Given the available dilution (i.e. 180), the receiving water monitoring requirements, the Discharger's analysis of the ocean discharge criteria as part of its application (See Appendix E.1 Ocean Discharge Criteria Response to CWA 403(c)), and USEPA's additional 403(c) analysis, USEPA makes a determination that the discharges authorized in this permit will not cause unreasonable degradation of the marine environment. 8. Federal Permit Renewal Contingency. The renewal of the Discharger's federal permit by USEPA is contingent upon determination by the U.S. Fish and Wildlife Service (USFWS) and NOAA National Marine Fisheries Service (NMFS) that the proposed discharge is consistent with the: (1) federal Endangered Species Act (ESA); (2) the Magnuson-Stevens Fishery Conservation and Management Act (MSA); and (3) the Santa Ana Water Board's certification/concurrence that the discharge will comply with applicable State water quality standards. USEPA's reissuance of NPDES No. CA0110604 to OC San is subject to requirements of the ESA and MSA. USEPA may decide that changes to this permit are warranted based on the results of the completed consultation and a reopener provision to this effect has been included in the Order/Permit. Issuance of this NPDES permit which incorporates both federal requirements and State waste discharge requirements will serve as the State's concurrence that the discharge complied with State water quality standards. The California Coastal Commission has indicated that it is not necessary to obtain a consistency ATTACHMENT F- FACT SHEET F-17 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS certification pursuant to the Coastal Zone Management Act for the issuance of a federal NPDES permit containing secondary treatment standards. 9. Endangered Species Act Requirements. This Order/Permit does not authorize any act that results in the taking of a threatened or endangered species or any act that is now prohibited, or becomes prohibited in the future, under either the California Endangered Species Act (Fish and Game Code, §§ 2050 to 2097) or the Federal Endangered Species Act (16 U.S.C.A. §§ 1531 to 1544). In July 2020, USEPA requested updated information related to: (1) essential fish habitat and managed and associated species, and (2) threatened and endangered species and their designated critical habitats, in the vicinity of the OC San's outfalls from NMFS. Subsequently, EPA and NMFS exchanged information about the facility, discharge characteristics, action area, OC San's monitoring program, and past consultations in Southern California. USEPA determined that the draft permit would have no effect on listed bird species; may affect but is not likely to adversely affect listed fish and abalone species; and is likely to adversely affect listed sea turtle, seal, and whale species. These effect determinations are explained in the biological evaluation. USEPA is consulting with the United States Fish and Wildlife Service and the National Marine Fisheries Service. This Order/Permit requires compliance with effluent limits, receiving water limits, and other requirements to protect beneficial uses, including protecting threatened and endangered species. The Discharger is responsible for meeting all requirements of the applicable Endangered Species Act. D. Impaired Water Bodies on the CWA section 303(d) List On April 6, 2018, USEPA issued a final decision regarding California's 2014- 2016 CWA Section 303(d) List of Impaired Waters. The list (hereinafter 303(d) list) identifies water bodies where water quality standards are not expected to be met after implementation of technology-based effluent limits by point sources. Huntington Beach State Park is included on the 303(d) list for PCBs (polychlorinated biphenyls). The offshore and nearshore zones off Huntington Beach State Park are the immediately affected receiving waters of discharges from the Facility. A total maximum daily load (TMDL) for PCBs is required but has not been established yet. As such, effluent limitations for PCBs have been established for the Facility until applicable waste load allocations are assigned in a TMDL. A TMDL to address the impairment is not currently scheduled for development. E. Other Plans, Polices and Regulations 1. Stringency of Requirements for Individual Pollutants. This Order/Permit contains technology-based effluent limitations and WQBELs for individual pollutants. Technology-based effluent limitations consist of restrictions on carbonaceous biochemical oxygen demand (5-day), total suspended solids, and pH which implement the minimum, applicable federal technology-based requirements for POTWs. Also, effluent limitations consisting of restrictions on oil and grease, settleable solids, and turbidity are necessary to implement State treatment standards in Ocean Plan Table 4. Discharge Point 001 WQBELs ATTACHMENT F- FACT SHEET F-18 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS consisting of restrictions on total chlorine residual, acute toxicity, chronic toxicity, radioactivity, benzidine, hexachlorobenzene, PCBs, TCDD equivalents, and toxaphene more stringent than federal technology-based limitations are necessary to meet State water quality standards in the Ocean Plan Table 3. Discharge Point 002 WQBELs consisting of restrictions on fecal coliform density, Enterococcus density, total chlorine residual, ammonia (as nitrogen), chronic toxicity, radioactivity, and TCDD equivalents more stringent than federal technology-based limitations are necessary to meet State water quality standards in the Ocean Plan Table 3. All effluent limitations are discussed in Attachment F-Fact Sheet. Collectively, the restrictions on individual pollutants in this Order/Permit are no more stringent than required by the CWA. 2. Federal Secondary Treatment Regulations. The OC San achieved full secondary treatment on December 28, 2012 and continues discharging secondary treated flow. 40 CFR § 133 establishes the minimum levels of effluent quality to be achieved by secondary treatment. These limitations, established by USEPA, are incorporated into this Order/Permit, except where more stringent limitations are required by other applicable plans, policies, or regulations or to prevent backsliding. 3. Industrial Storm Water Requirements. The Discharger is not required to be covered under the statewide NPDES general permit for storm water discharges associated with industrial activities (NPDES General Permit No. CAS000001) because all stormwater at the plants is collected by various drains and conveyed downstream of both plants' headworks for treatment. No storm water is diverted untreated to the outfalls. The Discharger has provided certification to the Santa Ana Water Board and USEPA that industrial storm water is managed by internal drainage systems at Reclamation Plant No. 1 and Treatment Plant No. 2, where storm water is captured, treated, and discharged with the treated wastewater regulated under this Order/Permit. This Order/Permit requires the Discharger to submit and implement a Storm Water Management Plan to address onsite storm water quality. 4. Sanitary Sewer Overflows. The State Water Board issued General Waste Discharge Requirements for Sanitary Sewer Systems, Water Quality Order 2006- 0003-DWQ (General Order) on May 2, 2006, which contains requirements for operation and maintenance of collection systems and for reporting and mitigating sanitary sewer overflows (SSOs). The Monitoring and Reporting Program for the General Order was amended through the State Water Board's Order WQ 2013- 0058-EXEC on August 6, 2013. This General Order requires public agencies that own or operate sanitary sewer systems with greater than one mile of pipes or sewer lines to enroll for coverage under the General Order. The General Order also requires agencies to develop sanitary sewer management plans and report all SSOs, among other requirements and prohibitions. The Discharger's collection system is part of the POTW that is subject to this Order/Permit. The Discharger must comply with both the General Order and this Order/Permit.

Pretreatment Requirements. In compliance with 40 CFR § 403, OC San has developed an approved Pretreatment Program for the POTW that it owns and operates. This Order/Permit includes the Discharger's approved Pretreatment Program and requires the Discharger to continue implementation and control of the Program throughout the service area of its POTW, including contributing jurisdictions. The POTW, as Control Authority, may exercise its authority over the entire service area directly, as provided by State law, or may elect to enter into contracts or other multi-jurisdictional agreements with contributing jurisdictions. In case the POTW elects to enter into inter-jurisdictional agreements, the POTW must ensure that discharges received from entities outside of its political boundaries are regulated to the same extent as are discharges within its political boundaries. OC San applies one set of local limits to all discharges to its treatment facilities. 6. Sewage Sludge/Biosolids Requirements. Section 405 of the CWA and implementing regulations at 40 CFR § 503 require that producers of sewage sludge/biosolids meet certain reporting, handling, and use or disposal requirements. The State has not been delegated the authority to implement this program; therefore, USEPA is the implementing agency. This Order/Permit contains sewage sludge/biosolids requirements pursuant to 40 CFR § 503 that are applicable to the Discharger. 7. Standard and Special Provisions. Standard Provisions, which apply to all NPDES permits in accordance with 40 CFR § 122.41, and additional conditions applicable to POTWs in accordance with 40 CFR § 122.42, are provided in Attachment D. The Santa Ana Water Board and USEPA have also included in this Order/Permit Special Provisions applicable to the Discharger. The rationale for the Special Provisions contained in this Order/Permit is provided in this Fact Sheet. IV. RATIONALE FOR EFFLUENT LIMITATIONS AND DISCHARGE SPECIFICATIONS The CWA requires point source dischargers to control the amount of conventional, non- conventional, and toxic pollutants that are discharged into the waters of the United States. The control of pollutants discharged is established through effluent limitations and other requirements in NPDES permits. There are two principal bases for effluent limitations in the Code of Federal Regulations: 40 CFR § 122.44(a) requires that permits include applicable technology-based limitations and standards; and 40 CFR § 122.44(d) requires that permits include water quality-based effluent limitations to attain and maintain applicable numeric and narrative water quality criteria to protect the beneficial uses of the receiving water. A. Discharge Prohibitions Discharge Prohibitions in this Order/Permit are based on Ocean Plan discharge prohibitions, Basin Plan discharge prohibitions, and discharge prohibitions in the existing Order/Permit. ATTACHMENT F- FACT SHEET F-20 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS 1. California Ocean Plan Discharge Prohibitions a. Prohibition 1113, III.C, III.D, III.E, and III.F: This permit/order implements discharge prohibitions that are applicable under sections 111.1.1.a, 111.1.2.a, 111.1.3.a, 111.1.4.a, and 111.1.6 of the 2019 California Ocean Plan, respectively. b. Prohibition III.G (Discharge at Discharge Point 001 without minimum initial dilution of at least 181:1): This prohibition is necessary to ensure that the assumption used to derive the dilution credits established through this Order/Permit remains substantially the same so that the effluent limitations are protective of water quality. This Order considered a dilution credit of 180 (Dm = 180) based on the Discharger's GWRS Final Expansion Final Implementation Plan, Project No. SP-173, Effluent Reuse Study (October 2016) to conduct the reasonable potential analysis described in Section IV.C.3 of this Fact Sheet. Moreover, the instream waste concentration (IWC) for the chronic toxicity effluent limitation is based on this dilution credit. When future discharge flows drop below 32 MGD, as a result of GWRS final expansion project, the outfall will likely need to be retrofitted to ensure adequate dilution and to prevent seawater intrusion and potential diffuser plugging. The initial dilution of 181:1 assumes that all 503 outfall ports are operational. 2. Santa Ana River Basin Plan Discharge Prohibitions a. Prohibition III.H, 111.1, and III.J: This permit/order implements discharge prohibitions that are applicable under Chapter 5, Waste Discharge Prohibitions A, B.1, and B.2 of the 2019 Basin Plan, respectively. 3. Prohibition III.K (Discharge from any locations other than Discharge Point 001): This prohibition clarifies that any discharges other than those to Discharge Point 001 are unauthorized, except those to Discharge Point Nos. 002 and 003 as explicitly authorized during essential maintenance or an emergency. B. Technology-Based Effluent Limitations (TBELs) 1. Scope and Authority Section 301(b) of the CWA and implementing USEPA permit regulations at 40 CFR § 122.44 require that permits include conditions meeting applicable technology-based requirements at a minimum, and any more stringent effluent limitations necessary to meet applicable water quality standards. The discharge authorized by this Order/Permit must meet minimum federal technology-based effluent limitations (TBELs) based on secondary treatment standards for POTWs at 40 CFR § 133. The CWA requires that technology-based effluent limitations be established based on several levels of controls: a. Best practicable treatment control technology (BPT) represents the average of the best existing performance by well-operated facilities within an industrial ATTACHMENT F- FACT SHEET F-21 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS category or subcategory. BPT standards apply to toxic, conventional, and non-conventional pollutants. b. Best available technology economically achievable (BAT) represents the best existing performance of treatment technologies that are economically achievable within an industrial point source category. BAT standards apply to toxic and non-conventional pollutants. c. Best conventional pollutant control technology (BCT) represents the control from existing industrial point sources of conventional pollutants including BOD, TSS, fecal coliform, pH, and oil and grease. The BCT standard is established after considering a two-part reasonableness test. The first test compares the relationship between the costs of attaining a reduction in effluent discharge and the resulting benefits. The second test examines the cost and level of reduction of pollutants from the discharge from publicly- owned treatment works to the cost and level of reduction of such pollutants from a class or category of industrial sources. Effluent limitations must be reasonable under both tests. d. New source performance standards (NSPS) represent the best available demonstrated control technology standards. The intent of NSPS guidelines is to set limitations that represent state-of-the-art treatment technology for new sources. The CWA requires USEPA to develop effluent limitations, guidelines and standards (ELGs) representing application of BPT, BAT, BCT, and NSPS. Section 402(a)(1) of the CWA and 40 CFR § 125.3 authorize the use of best professional judgment (BPJ) to derive technology-based effluent limitations on a case-by-case basis where ELGs are not available for certain industrial categories and/or pollutants of concern. Where BPJ is used, the Santa Ana Water Board and USEPA must consider specific factors outlined in 40 CFR § 125.3. Regulations promulgated in 40 CFR § 125.3(a)(1) require technology-based effluent limitations for municipal Dischargers to be placed in NPDES permits based on Secondary Treatment Standards or Equivalent to Secondary Treatment Standards. The Federal Water Pollution Control Act Amendments of 1972 (PL 92-500) established the minimum performance requirements for POTWs [defined in section 304(d)(1)]. Section 301(b)(1)(B) of that Act requires that such treatment works must, as a minimum, meet effluent limitations based on secondary treatment as defined by the USEPA Administrator. Based on this statutory requirement, USEPA developed secondary treatment regulations, which are specified in 40 CFR § 133. These technology-based regulations apply to all municipal wastewater treatment plants and identify the minimum level of effluent quality attainable by secondary treatment in terms of biochemical oxygen demand (BOD5), total suspended solids (TSS), and pH. ATTACHMENT F- FACT SHEET F-22 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS Table F-7. Federal Secondary Treatment Standards Parameter Units 30-day Average 7-day Average BODS mg/L 30 45 influent % removal not less than 85 -- CBOD5 mg/L 25 40 (if substituted) influent % removal not less than 85 TSS -- mg/L 30 45 influent % removal not less than 85 -- pH standard units 6.0 — 9.0 at all times On May 13, 2004, the Discharger requested the inclusion of effluent limitations for five-day carbonaceous biochemical oxygen demand (CBOD5), as allowed by 40 CFR § 133.102(a)(4), for the period following completion of expanded secondary treatment facilities. In the 2004 Order/Permit, CBOD5 effluent limitations were applied to the final effluent during partial or full nitrification at the Discharger's secondary treatment facilities, where effluent nitrification is used to reduce ammonia toxicity associated with wastewater treatment and RO concentrate flow from the Groundwater Replenishment System. As nitrifying bacteria use oxygen to degrade nitrogenous compounds otherwise not significantly removed in the secondary treatment process, higher oxygen demand values for the final effluent result. Consequently, the use of CBOD5 effluent limits have been found to ensure that federal secondary treatment standards for POTWs are achieved while allowing the Discharger to use the treatment process of nitrification to reduce ammonia toxicity in the discharged effluent and comply with Ocean Plan requirements for acute and chronic toxicity. CBOD5 effluent limitations have been carried over to this Order/Permit and are applied in lieu of BOD5 effluent limitations. The effluent limitations consisting of restrictions on grease and oil, settleable solids, and turbidity are necessary to implement State treatment standards in Ocean Plan Table 4, which are summarized as follows. Table F-8.

The 2012 Order/Permit established mass emission effluent limitations based on the average daily influent flow projected for 2017 (i.e., 274 MGD). For Discharge Point 001, this Order/Permit establishes mass emission effluent limitations for TBELs based on the average daily upper bound influent flow of 206 MGD projected for 2025, taken from the Discharger's 2017 Master Plan. For Discharge Point 002, mass emission effluent limitations for TBELs continue to be based on the Discharger's conservative estimate for hydraulic flow capacity of the 78-inch outfall of 230 MGD. 2. Applicable Technology-Based Effluent Limitations A summary of the applicable technology-based effluent limitations is shown in Tables F-14 and F-15, in section IV.E of this Fact Sheet. C. Water Quality-Based Effluent Limitations (WQBELs) 1. Scope and Authority CWA Section 301(b) and 40 CFR § 122.44(d) require that NPDES permits include limitations more stringent than applicable federal technology-based requirements where necessary to achieve applicable water quality standards and State requirements. Section 122.44(d)(1)(i) of 40 CFR requires that permits include effluent limitations for all pollutants that are or may be discharged at levels that have the reasonable potential to cause or contribute to an exceedance of a water quality standard, including numeric and narrative objectives within a standard. Where reasonable potential has been established for a pollutant, but there is no numeric criterion or objective for the pollutant, water quality-based effluent limitations (WQBELs) must be established using: (1) USEPA criteria guidance under CWA section 304(a), supplemented where necessary by other relevant information; (2) an indicator parameter for the pollutant of concern; or (3) a calculated numeric water quality criterion, such as a proposed state criterion or policy interpreting the state's narrative criterion, supplemented with other relevant information, as provided in section 122.44(d)(1)(vi). USEPA has applied CWA section 403(c) and 40 CFR § 125, Subpart M, following 40 CFR § 122. The process for determining reasonable potential and calculating WQBELs when necessary is intended to protect the designated uses of the receiving water as specified in the Basin Plan, and achieve applicable water quality objectives and ATTACHMENT F- FACT SHEET F-24 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS criteria that are contained in other state plans and policies, or any applicable water quality criteria contained in the Ocean Plan. 2. Applicable Beneficial Uses and Water Quality Criteria and Objectives The Basin Plan and Ocean Plan designate beneficial uses, establish water quality objectives, and contain implementation programs and policies to achieve those objectives for all waters of the State. Applicable beneficial uses designated within the Basin Plan and Ocean Plan are listed in Tables F-5 and F-6, in section III.0 of this fact sheet. The Basin Plan contains Water Quality Objectives for bacteria for water bodies designated for water contact recreation. The Ocean Plan establishes applicable water quality objectives for the protection of marine aquatic life and human health. The Ocean Plan also includes water quality objectives for bacterial characteristics, physical characteristics, chemical characteristics, biological characteristics, and radioactivity. The water quality objectives from the Ocean Plan and Basin Plan were incorporated into this Order/Permit as either final effluent limitations (based on reasonable potential) or receiving water limitations. 3. Determining the Need for WQBELs a. RPA Methodology The 2012 Order/Permit (Order No. R8-2012-0035) contains WQBELs for pollutant parameters based on Table B of the 2009 Ocean Plan. For this Order/Permit, the need for WQBELs based on water quality objectives in Table 3 of the 2019 Ocean Plan was statistically reevaluated in accordance with the Reasonable Potential Analysis (RPA) procedures contained in Appendix VI of the 2019 Ocean Plan. The statistical RPA method accounts for the averaging period of the water quality objective, accounts for and captures the long-term variability of the pollutant in the effluent, accounts for limitations associated with sparse data sets, accounts for uncertainty associated with censored data sets, and assumes a lognormal distribution of the facility-specific effluent data. The program calculates the upper confidence bound (UCB) of an effluent population percentile after complete mixing. In the evaluation employed in this Order/Permit, the UCB is calculated as the one-sided, upper 95 percent confidence bound for the 95th percentile of the effluent distribution after complete mixing. The calculated UCB95/95 is then compared to the appropriate water quality objective to determine the potential for an exceedance of that objective and the need for a WQBEL. For constituents that have an insufficient number of monitoring data or a substantial number of non- detected data with a reporting limit higher than the respective water quality objective, the RPA result is likely to be inconclusive. According to the Ocean Plan RPA procedure, the RPA can yield three endpoints: ATTACHMENT F- FACT SHEET F-25 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS Endpoint 1: An effluent limitation must be developed, and effluent monitoring for the pollutant is required; Endpoint 2: An effluent limitation is not required, but the Santa Ana Water Board and/or USEPA may require monitoring for the pollutant or for the whole effluent toxicity (WET) as appropriate; or Endpoint 3: The RPA is inconclusive, and monitoring for the pollutant or WET testing is required. An existing effluent limitation shall remain in the permit, otherwise a permit reopener clause shall be included to allow for subsequent modification of the permit to include an effluent limitation if the monitoring establishes that the discharge causes, has the reasonable potential to cause, or contributes to an excursion above the appropriate water quality objective. b. Minimum Initial Dilution or Dilution Credits The Discharger updated its dilution analysis as part of the planning process for the GWRS final expansion project (GWRS Final Expansion Final Implementation Plan, Project No. SP-173, Effluent Reuse Study, October 2016). The updated modeling included calibrating current conditions with the modeling completed in 2002 and 2008. The updated modeling continued to use NRFIELD in Visual Plumes, consistent with the past modeling. The analysis included various scenarios for flow rates, including low effluent flows as the result of the GWRS final expansion project, densities (i.e. temperature and salinity changes based on low effluent flows), and critical stratification conditions (i.e. August to October 2014). The analysis shows that dilution is unlikely to be impacted by the increase in RO concentrate discharged because the total discharge flow will be decreased. As to be expected, model results were the most sensitive to discharge flow rate and stratification and ranged from 151 :1 to 363:1 for the various scenarios. Based on the updated modeling, the Santa Ana Water Board and USEPA is carrying over the dilution ratio of 181:1, as this dilution (Dm = 180) is a representative of reasonable worst-case scenario (i.e. high discharge flow rate under strong stratified conditions) and is consistent with antidegradation and anti- backsliding requirements. With exception of radioactivity, the dilution ratio of 181 :1 (Dm = 180) has been applied to the final effluent limitations for Discharge Point No. 001 . The dilution ratio of 37:1 (Dm = 36) also has retained for Discharge Point No. 002 in this Order/Permit. Based on the Ocean Plan, water quality objectives for radioactivity shall apply directly to the undiluted waste effluent (i.e., Dm = 0 for radioactivity). c. RPA for Pollutants in Table 3 of the Ocean Plan RPAs were conducted using the State Water Board's RPcalc 2.0 software tool and minimum probable initial dilution values for Discharge Point 001 (i.e., Dm = 180) and Discharge Point 002 (i.e., Dm = 36), except for radioactivity.

CA0110604 COLLECTION SYSTEM & OUTFALLS Effluent data provided in the Discharger's monitoring reports from May 2015 to December 2019, after the Discharger achieved full secondary treatment and ceased disinfection, were used in the analyses in order to be representative of current performance. The results of these RPAs are summarized in Table F-9 for Discharge Point 001 (120" outfall) and Table F- 10 for Discharge Point 002 (78" outfall). Based on the RPA for Discharge Point 001, Endpoint 1 is established for total chlorine residual. Consequently, WQBELs for total chlorine residual are included in the Order/Permit and periodic effluent monitoring is also required. The Discharger ceased continuous effluent disinfection using chlorination/dechlorination at Discharge Point 001 (120" outfall). However, sodium hypochlorite has been used as oxidant chemical to treat foul air (i.e., HzS control) in scrubbers at primary treatment process and to control the bulking from filamentous organisms in the return activated sludge (RAS), which probably causes RP for total chlorine residual. Endpoint 2 is established for the majority of detected Table 3 pollutants. Consequently, WQBELs for these pollutants are not included in the Order/Permit, but periodic effluent monitoring for all Endpoint 2 pollutants is required. Endpoint 3 with inconclusive results was reported for benzidine, hexachlorobenzene, PCBs, TCDD equivalents, and toxaphene. Consequently, existing WQBELs for these five pollutants are retained in this Order/Permit and periodic effluent monitoring is also required. This Order/Permit does not include effluent limitations for other pollutants displaying Endpoint 3; instead, monitoring requirements for those pollutants were included. Based on the RPA for Discharge Point 002, Endpoint 1 is established for ammonia (as nitrogen), and total chlorine residual. Consequently, WQBELs for ammonia and total chlorine residual are included in the Order/Permit and periodic effluent monitoring is also required. Endpoint 2 is established for the majority of detected Table 3 pollutants. Consequently, WQBELs for these pollutants are not included in the Order/Permit, but periodic effluent monitoring for all Endpoint 2 pollutants is required. Endpoint 3 with inconclusive results was reported for TCDD equivalents and thus, existing WQBELs and quarterly effluent monitoring for TCDD equivalents are retained in this Order/Permit. This Order/Permit does not include effluent limitations for other pollutants displaying Endpoint 3; instead, monitoring requirements for those pollutants were included. Step 13 of the RPA procedures in the Ocean Plan authorizes RPA based on best professional judgment (BPJ). Information may include the facility type, discharge type, solids loading analysis, lack of dilution, history of compliance problems, potential toxic impact of discharge, fish tissue residue data, water quality and beneficial uses of the receiving water, CWA 303(d) listing for the pollutant, the presence of endangered or threatened species or critical habitat, and other information. Based on Step 13 of the Ocean Plan (i.e., BPJ), reasonable potential for acute and chronic toxicity has been established ATTACHMENT F- FACT SHEET F-27 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS for Discharge Point 001 and chronic toxicity for Discharge Point 002 because toxicity levels at POTWs can exceed applicable water quality standards, and numerical water quality objectives/criteria for the majority of chemical pollutants have not been established. In addition, reasonable potential for radioactivity has been established for Discharge Points 001 and 002 because POTWs accept waste from various facilities, including hospitals that could potentially discharge radioactivity into the sewershed, and the Discharger's wastewater treatment plants are not typically designed to remove radioactivity from the effluent. The discharge also had detectable concentrations of radioactivity (i.e., maximum effluent concentration (MEC) for gross alpha of 36 pCi/L and MEC for gross beta of 70 pCi/L). Thus, WQBELs for acute/chronic toxicity and radioactivity at Discharge Point 001 and a WQBLEL for chronic toxicity and radioactivity at Discharge Point 002 are included in this Order/Permit.

Concentration-based WQBEL Calculations From the Table 3 water quality objectives in the 2019 Ocean Plan, concentration-based WQBELs are calculated according to the following equation for all pollutants, except for acute and chronic toxicity (if applicable): Ce = Co + DM(Co — Cs) Where, Ce = the effluent limitation Co = the water quality objective to be met at the completion of initial dilution CS = background seawater concentration (see Table F-11 below) DM = minimum probable initial dilution expressed as parts seawater per part wastewater (i.e., 180 for Discharge Point 001 and 36 for Discharge Point 002) Background seawater concentration for all Table 3 pollutants is assumed to be zero (Cs = 0), except for the following five pollutants: Table F-11.

All calculations are based on discharge through Discharge Point 002 and, therefore, a dilution ratio (Dm) of 36 is applied. Example - Copper Ce = 3 + 36 (3 — 2) = 39 µg/L (6-month Median) Ce = 12 + 36 (12 — 2) = 372 µg/L (Maximum Daily) Ce = 30 + 36 (30 — 2) = 1,038 µg/L (Instantaneous Maximum) Total Chlorine Residual Ce = 2 + 36 (2 — 0) = 74 µg/L (6-month Median) Ce = 8 + 36 (8 — 0) = 296 µg/L (Maximum Daily) Ce = 60 + 36 (60 — 0) = 2,220 µg/L (Instantaneous Maximum) Ammonia Ce = 0.6 + 36 (0.6 — 0) = 22.2 mg/L (6-month Median) Ce = 2.4 + 36 (2.4 — 0) = 88.8 mg/L (Maximum Daily) Ce = 6 + 36 (6 — 0) = 222 mg/L (Instantaneous Maximum) TCDD equivalents Ce = 3.9x10-9 + 36 (3.9X10-9 — 0) = 144.3x10-9 µg/L = 0.144 pg/L (Average Monthly) b. Mass-based WQBEL Calculations The following equation from the 2019 Ocean Plan Chapter III.C.4.j is used to calculate all mass-based WQBELs. Mass (in Ibs/day) = 0.00834 x Ce x Q where: Ce = the effluent concentration limitation (µg/L) Q = flow rate (MGD) For example, in the case of PCBs where Q = 206 MGD for Discharge Point 001, the average monthly mass-based WQBEL is: Ce = 0.00834 x 0.0034 µg/L x 206 MGD = 0.0058 Ibs/day For Discharge Point 001 (120" outfall), the previous Order/Permit established mass emission effluent limitations based on the average daily influent flow (Q) of 274 MGD projected for 2017. This Order/Permit establishes mass emission effluent limitations based on the average daily upper bound influent flow of 206 MGD projected for 2025, which was taken from the Discharger's 2017 Master Plan. For Discharger Point ATTACHMENT F- FACT SHEET F-39 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS 002 (78" outfall), consistent with the previous permit, mass emission effluent limitations are based on the Discharger's conservative estimate for the hydraulic flow capacity of the 78" outfall (Q) of 230 MGD. Since Discharge Point 002 is authorized for emergency situations, it is anticipated to use its maximum hydraulic flow capacity of 230 MGD during emergency discharges. C. Bacteria WQBEL Calculations Bacteria effluent limitations for Discharge Point 002 remain in the Order/Permit to ensure protection of human health and receiving water quality for REC-1 beneficial uses and compliance with REC-1 water quality objectives for bacteria in the Pacific Ocean. The Ocean Plan was amended in 2018 to revise the bacterial objectives for ocean waters used for water contact recreation, which includes removal of the previously established total coliform objectives and the revised enterococci objectives based on the EPA 2012 Recreational Criteria for marine waters. This Order/Permit has established bacteria effluent limitations at Discharge Point 002 (78" outfall) based on the amended water quality objectives in Table 1 and 2 of the 2019 Ocean Plan. Fecal coliform and enterococcus WQBELs for Discharge Point 002 are determined using the equation, Ce=Co+Dm(Co-CS) and an Initial dilution of 37:1 (Dm=36). The background conditions for fecal coliform and enterococcus are assumed to be zero. Table F-13.

R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES N0. CA0110604 COLLECTION SYSTEM & OUTFALLS 5. Whole Effluent Toxicity (WET) Whole Effluent Toxicity (WET) testing protects receiving waters from the aggregate toxic effect of a mixture of pollutants in the effluent or pollutants that are not typically monitored. An acute toxicity test is conducted over a short time period and measures mortality. A chronic toxicity test is conducted over a short or a longer period of time and measures a sublethal endpoint such as reproduction or growth, and sometimes mortality. Because of the nature of industrial discharges and contaminants of emerging concern (CEC) used in households such as PPCPs, pesticides and PFAS which may be released into the POTW sewershed, toxic constituents in and of itself or in combination may be present in the effluent. A total of 71 chronic and 26 acute WET tests was conducted on the effluent discharged to Discharge Point 001 (120" outfall) between May 2015 and December 2019. None of the testing results was reported as "Fail" for both acute and chronic toxicity. However, based on Step 13 of the RPA procedures in the Ocean Plan (i.e., best professional judgement), reasonable potential for acute and chronic toxicity has been established for Discharge Point 001 and chronic toxicity for Discharge Point 002 due to potentially toxic chemicals exceeding water quality standards and numerous chemicals having no specific water quality standard. Therefore, the protection of aquatic life through the evaluation of toxicity monitoring is necessary to examine the potential for the individual and/or combination of toxic chemicals that pass through the POTW. The Ocean Plan addresses the application of chronic and acute toxicity requirements based on minimum probable initial dilutions (Dm) for ocean discharges. Following the Ocean Plan, dischargers are required to conduct chronic toxicity monitoring for ocean discharges with Dm factors ranging from 99 to 349; also, Santa Ana Water Boards or USEPA may require acute toxicity monitoring in addition to chronic toxicity monitoring. Dischargers with Dm factors below 99 are required to conduct only chronic toxicity testing. Since the Dm for Discharge Point 001 is 180, both acute and chronic toxicity final effluent limitations have been assigned to Discharge Point 001. Since the Dm for Discharge Point 002 (i.e., Dm = 36) is less than 99, only chronic toxicity monitoring is specified for Discharge Point 002. No acute toxicity final effluent limitations have been assigned to Discharge Point 002 consistent with 40 CFR § 122.44(d)(1)(v), and because the chronic toxicity final effluent limitation is protective of both chronic and acute toxicity. The Ocean Plan establishes a daily maximum chronic toxicity objective of 1.0 TUB = 100/NOEC and a daily maximum acute toxicity objective of 0.3 TUa = 100/1-050. In 2010, USEPA published a guidance document titled National Pollutant Discharge Elimination System Test of Significant Toxicity Implementation Document (EPA 833-R-10-003, 2010), in which they recommend the following: "Permitting authorities should consider adding the Test of Significant Toxicity (TST) statistical approach to their implementation procedures for analyzing valid WET data for their current NPDES WET Program." The TST hypothesis testing ATTACHMENT F- FACT SHEET F-41 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS approach more reliably identifies toxicity—in relation to the chronic (equal to or greater than 0.25) and acute (equal to or greater than 0.20) mean responses of regulatory management decision—than the NOEC hypothesis-testing approach used in the Ocean Plan. The TST statistical approach is the improved approach for addressing statistical uncertainty when used in combination with USEPA's toxicity test methods and is implemented in federal permits issued by USEPA Region 9. Therefore, this Order/Permit includes final effluent limitations for both Discharge Point 001 (120"outfall) and Discharge Point 002 (78" outfall) using the TST hypothesis testing approach. This statistical approach is consistent with the Ocean Plan in that it provides maximum protection to the environment since it more reliably identifies acute and chronic toxicity than the NOEC hypothesis- testing approach (See Chapter III.F and Appendix I of the 2019 California Ocean Plan). The discharge is subject to determination of "Pass" or "Fail" from acute and/or chronic toxicity tests using the TST statistical t-test approach described in the National Pollutant Discharge Elimination System Test of Significant Toxicity Implementation Document (USEPA 833-R-10-003, 2010), Appendix A, Figure A- 1, Table A-1, and Appendix B, Table B-1. The TST's null hypothesis (Ho) for chronic toxicity is: Ho: Mean discharge In-stream Waste Concentration (IWC) response :50.75 x Mean control response. The TST's null hypothesis (Ho) for acute toxicity is: Ho: Mean discharge In-stream Waste Concentration (IWC) response :50.80 x Mean control response. A test result that rejects this null hypothesis is reported as "Pass." A test result that does not reject this null hypothesis is reported as "Fail." WQBEL Calculation for Chronic Toxicity (Discharge Points 001 and 002) The chronic toxicity WQBEL for Discharge Point 001 is expressed as a null hypothesis (Ho) and regulatory management decision (b value) of 0.75 for the chronic toxicity methods in Attachment E — Monitoring and Reporting Program. The chronic toxicity In-stream Waste Concentration (IWC) is 100/Dm = 100/180 = 0.556% for Discharge Point 001 (120" outfall) and IWC = 100/36 = 2.78% for Discharge Point 002 (78" outfall). The null hypothesis for chronic toxicity at Discharge Point 001 is: Ho: Mean response (0.556% effluent) <_ 0.75 mean response (Control) The null hypothesis for chronic toxicity at Discharge Point 002 is: Ho: Mean response (2.78% effluent) <_ 0.75 mean response (Control) WQBEL Calculation for Acute Toxicity (Discharge Point 001) ATTACHMENT F- FACT SHEET F-42 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS The acute toxicity WQBEL for Discharge Point 001 is expressed as a null hypothesis (Ho) and regulatory management decision (b value) of 0.80 for the acute toxicity methods in Attachment E — Monitoring and Reporting Program. The acute toxicity In-stream Waste Concentration (in % effluent) for Discharge Point 001 is 100/(0.1*Dm) = 100/(0.1*180) = 5.56%. The null hypothesis for acute toxicity at Discharge Point 001 is: Ho: Mean response (5.56% effluent) <_ 0.80 mean response (Control). Results obtained from evaluating statistically the IWC compared to the control shall be analyzed using the TST hypothesis testing approach in Attachment E — Monitoring and Reporting Program. Compliance with these acute and chronic toxicity WQBELs is demonstrated by rejecting the null hypothesis and reporting "Pass" or "P". The Maximum Daily Effluent Limitation (MDEL) for acute or chronic toxicity is exceeded and a violation will be flagged when WET test, analyzed using the TST statistical approach, results in "Fail". D. Final Effluent Limitation Considerations 1. Anti-Backsliding Requirements Sections 402(o) and 303(d)(4) of the CWA and federal regulations at 40 CFR § 122.44(I) prohibit backsliding in NPDES permits. These anti-backsliding provisions require effluent limitations in a reissued permit to be as stringent as those in the previous permit, with some exceptions where limitations may be relaxed. All effluent limitations and conditions in this Order/Permit are at least as stringent as those in the previous Order/Permit. This Order/Permit implements different bacteria indicators and water quality objectives based on Chapter II.B.1 of the 2019 Ocean Plan (i.e., State Water Board Water-Contact Objectives for Bacteria). The California Ocean Plan was amended in 2018 to revise the bacterial objectives for ocean waters used for water contact recreation, which includes removal of the previously established total coliform objectives and the revised enterococci objectives based on the EPA 2012 Recreational Criteria for marine waters. This Order/Permit has established bacteria effluent limitations at Discharge Point 002 (78" outfall) based on the amended objectives in the 2019 Ocean Plan. The new effluent limitations are expressed using different averaging periods than the previous limits and are therefore not directly comparable. 2. Antidegradation Policies Pursuant to 40 CFR 131.12, the state water quality standards must include an antidegradation policy consistent with the federal antidegradation policy. The State Water Board established California's antidegradation policy in State Water Board Resolution No. 68-16. This resolution incorporates the federal antidegradation policy, where the federal policy applies under federal law. Resolution No. 68-16 requires that existing water quality be maintained unless it is demonstrated that any degradation is consistent with the maximum benefit to ATTACHMENT F- FACT SHEET F-43 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS the people of the State, will not unreasonably affect current or possible beneficial uses, and will not result in water quality less than prescribed in applicable policies. A complete antidegradation analysis is required if the proposed activity results in a substantial increase in mass emissions of pollutants or if the activity results in significant impact to aquatic life. It is not necessary to do a complete antidegradation analysis if the reduction in water quality will be spatially localized or limited with respect to the waterbody. In such cases, a simple antidegradation analysis will suffice. The Santa Ana Water Board and USEPA believe that the simple antidegradation analysis presented herein is consistent with California and Federal antidegradation policies because effects from effluent discharges are spatially and temporally limited and not expected to have a significant impact on receiving water quality. This Order/Permit includes both narrative and numeric final effluent limitations, receiving water limitations, performance goals, and mass emission benchmarks to maintain the chemical, physical, and biological characteristics, and to protect the beneficial uses, of the receiving water. These requirements ensure that all water quality objectives are being met outside the zone of initial dilution, thereby maintaining the beneficial uses. The Ocean Plan allows for minimal degradation within the zone of initial dilution as long as the water quality objectives are maintained just outside the zone of initial dilution. The minimal degradation permitted by the Ocean Plan is consistent with the antidegradation policy because it maintains maximum benefit to the people of the State, it will not unreasonably affect the present and anticipated beneficial uses, and it will not result in water quality less than that prescribed in the policies. The final effluent limitations from the previous Order/Permit have been retained. Bacteria limits at Discharge Point 002 (78" outfall) were updated to implement new State water quality objectives for bacteria in the 2019 Ocean Plan. The new effluent limitations for fecal coliform and enterococcus are consistent with the State's antidegradation policy because the discharge is in compliance with new State Water Board water-contact objectives for bacteria in the Pacific Ocean. In addition, receiving water limitations for bacteria are included to further limit bacteria and to ensure that any increase in the bacteria levels due to cessation of disinfection at Discharge Point 001 (120" outfall) will be maintained below the applicable bacteria water quality standards. Full secondary treatment and these bacteria limitations will ensure that undisinfected effluent discharges will not adversely impact human health and receiving water quality for REC-1 beneficial uses. The performance goal and mass emission benchmarks are additional incentives for the Discharger to maintain the current treatment quality since they set final effluent targets for the Discharger to meet based on current performance. Most mass emission benchmarks in this Order/Permit are more stringent due to improved performance by full secondary treatment and a basis of lower flow rate (i.e., the average daily influent flow of 206 MGD projected for 2025); however, the ATTACHMENT F- FACT SHEET F-44 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS mass emission benchmarks for some constituents (e.g., selenium) have increased due to increased concentrations in the influent and/or more sensitive analysis methods. Since the mass emission benchmarks are based on actual performance and do not exceed the water quality objectives for the receiving water, the increase of any mass emission benchmarks is not expected to result in additional degradation. Compliance with all permit-specified concentration-based and mass emission- based limits, performance goals, mass emission benchmarks, and the secondary treatment requirements for final effluent discharges in the Order/Permit will result in the use of best practicable treatment or control of the discharge necessary to assure that a pollution or nuisance will not occur and that the highest water quality consistent with the maximum benefit to the people of the state will be maintained. Additionally, the secondary treatment facilities would support the Groundwater Replenishment System, reduce the effluent discharge volumes to the ocean, and reduce the need for emergency use of Discharge Point 002 (78" short outfall). Therefore, it is believed that these changes would represent socioeconomic and public benefits, and the Discharger meets the goals of the antidegradation policy. Based on these considerations, this Order/Permit is consistent with state and federal antidegradation requirements. 3. Stringency of Requirements for Individual Pollutants This Order contains both technology-based and water quality-based effluent limitations for individual pollutants. The technology-based effluent limitations consist of restrictions on biochemical oxygen demand (5-day), carbonaceous biochemical oxygen demand (5-day), total suspended solids, and pH which implement the minimum, applicable federal technology-based requirements for POTWs. Also, effluent limitations consisting of restrictions on oil and grease, settleable solids, and turbidity more stringent than federal technology-based limitations are necessary to implement State treatment standards in Ocean Plan Table 4. Water quality-based effluent limitations (WQBELs) have been derived to implement water quality objectives that protect beneficial uses. Both the beneficial uses and the water quality objectives have been approved pursuant to federal law and are the applicable federal water quality standards. The procedures for calculating the individual WQBELs are based on the Ocean Plan, which was approved by USEPA on February 14, 2006 and has since been further amended. All beneficial uses and water quality objectives contained in the Basin Plan were approved under state law and submitted to and approved by USEPA prior to May 30, 2000. Any water quality objectives and beneficial uses submitted to USEPA prior to May 30, 2000, but not approved by USEPA before that date, are nonetheless "applicable water quality standards for purposes of the CWX pursuant to 40 CFR § 131.21(c)(1). Discharge Point 001 WQBELs consisting of restrictions on total chlorine residual, acute toxicity, chronic toxicity, radioactivity, benzidine, hexachlorobenzene, ATTACHMENT F- FACT SHEET F-45 ORANGE COUNTY SANITATION DISTRICT ORDER NO.

Performance Goal Section III.F.1 , of the 2019 Ocean Plan allows the Santa Ana Water Board to establish more restrictive water quality objectives and effluent limitations than those set forth in the Ocean Plan as necessary for the protection of the beneficial uses of ocean waters. Pursuant to this provision, performance goals that are more stringent than those based on Ocean Plan objectives are prescribed in this Order/Permit. This approach is consistent with the antidegradation policy in that it requires the Discharger to maintain its treatment level and effluent quality, recognizing normal variations in treatment efficiency and sampling and analytical techniques. However, this approach does not address substantial changes in treatment plant operations that could significantly affect the quality of the treated effluent. While performance goals were previously placed in many State-issued NPDES permits for POTWs, they have been discontinued for inland surface water discharges. For inland surface waters, the California Toxics Rule (40 CFR § 131.38) has resulted in effluent limitations as stringent as many performance goals. However, the Ocean Plan allows for significant dilution, and the continued use of performance goals serves to maintain existing treatment levels and effluent quality and supports State and federal antidegradation policies. The performance goals are based upon the last 5-year actual performance of the OC San's treatment plants and are specified only as an indication of the treatment efficiency of the Facility. The performance goals are not considered enforceable effluent limitations or standards for the regulation of discharge from the treatment facility. They are intended to minimize pollutant loading (primarily for toxics), while maintaining the incentive for future voluntary improvement of water quality whenever feasible, without the imposition of more stringent limits based on improved performance. The Discharger shall maintain existing treatment levels and the effluent quality at or below the performance goal concentrations. Any two consecutive exceedances of the performance goals shall trigger an investigation into the cause of the exceedance. If the exceedance persists in three successive monitoring periods, the Discharger shall submit a written report to the Santa Ana Water Board and USEPA on the nature of the exceedance and the results of the investigation including the cause of the exceedance. The Santa Ana Water Board and USEPA recognize that OC San is going through upgrades of treatment plant operations including the GWRS final expansion and ATTACHMENT F- FACT SHEET F-50 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS participating in collaborative studies and activities with regional partnerships. This Order/Permit may be reopened to modify any of the performance goals if the Discharger requests and has demonstrated that the change is warranted, including results of completion of the GWRS final expansion. Procedures for the Determination of Performance Goals 1. For constituents that have been routinely detected in the effluent (at least 20 percent detectable data), performance goals are based on the one-sided, upper 95 percent confidence bound for the 95t" percentile of the effluent performance data (UCB95/95) from May 2015 through December 2019 using the RPA protocol contained in the 2019 Ocean Plan. Effluent data are assumed log normally distributed. Performance goals are calculated according to the equation CPS _ Co+Dm(Co-Cs) and setting Co = UCB95/95. a. If the maximum detected effluent concentration (MEC) is greater than the calculated performance goal (CPc), then the calculated performance goal (CPc) is used as the performance goal; or b. If the MEC is less than the calculated performance goal (CPc), then the MEC is used as the performance goal. c. If the performance goal determined in part a or b above is greater than the Water Quality Objective (WQO) in the 2019 Ocean Plan after considering dilution, then the WQO is used as the performance goal. For example, the performance goals for arsenic and chloroform at Discharge Point 001 (120" outfall) are calculated as follows: Arsenic Co = UCB95/95 = 3.02 pg/L ; Dm= 180; Cs = background seawater concentration = 3 pg/L; MEC = 6.91 pg/L; CPc = Performance Goal = (3.02 pg/L) + 180*(3.02 fag/L - 3 fag/L) = 6.62 fag/L. Since the MEC of 6.91 fag/L is greater than the calculated PG of 6.62 fag/L, the prescribed performance goal for arsenic is 6.62 fag/L. Chloroform Co = UCB95/95 = 3.285 fag/L ; Dm= 180; Cs = background seawater concentration = 0 fag/L; MEC = 16.6 fag/L; CPc = Performance Goal = (3.285 fag/L) + 180*(3.285 fag/L - 0 fag/L) = 594.6 fag/L. Since the MEC of 16.6 fag/L is less than the calculated PG of 594.6 fag/L, the prescribed performance goal for chloroform is 16.6 pg/L. 2. For constituents where monitoring data have consistently shown nondetectable levels (less than 20 percent detectable data), performance goals are set at the multiplying factor of 2.13 times the Minimum Levels (ML) used for analysis, which is based on statistical procedures outlined in USEPA manual, the Technical Support Document for Water Quality-Based Toxics Control (TSD, 1991). These performance goals are estimated assuming a coefficient of variation of 0.6 and the ATTACHMENT F- FACT SHEET F-51 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS 95 percent confidence interval of the 95t" percentile based on an assumed lognormal distribution of daily efficient values (see Table 5-2 of USEPA's TSD) a. If the MEC is greater than the calculated performance goal based on ML (i.e., 2.13*ML), then the calculated performance goal (i.e., 2.13*ML) is used as the performance goal; or d. If the MEC is less than the calculated performance goal based on ML (i.e., 2.13*ML), then the MEC is used as the performance goal. e. If the performance goal determined in part a or b above is greater than the Water Quality Objective (WQO) in the 2019 Ocean Plan after considering dilution, then the WQO is used as the performance goal. For example, the performance goals for halomethanes and heptachlor at Discharge Point 001 (120" outfall) are calculated as follows: Halomethanes (5 detected out of 54 samples) MEC = 1.37 pg/L; ML = 0.2 pg/L; CPS = Performance Goal = 2.13*0.2 = 0.43 pg/L. Since the MEC of 1.37 fag/L is greater than the calculated PG of 0.43 fag/L, the prescribed performance goal for halomethanes is 0.43 pg/L Heptachlor (all nondetected) MEC = NA (all ND); ML = 0.01 pg/L; CPS = Performance Goal = 2.13*0.01 = 0.012 fag/L. Co = WQO = 0.00005 pg/L; Dm = 180; Cs = background seawater concentration = 0 fag/L; CPc = Performance Goal = (0.00005 fag/L) + 180*(0.00005 fag/L - 0 fag/L) _ 0.009 pg/L. Since the performance goal based on ML of 0.012 fag/L is greater than the calculated WQO-based performance goal of 0.009 pg/L, so the prescribed performance goal for heptachlor is 0.009 fag/L. 3. For constituents with effluent limitations, if the performance goal derived from the steps, above, exceeds respective effluent limitation, then a performance goal is not prescribed for that constituent. B. Mass Emission Benchmarks To address the uncertainty due to potential increases in toxic pollutant loadings from the discharge to the marine environment during the five-year Order/Permit term, and to establish a framework for evaluating the need for an antidegradation analysis to determine compliance with State and federal antidegradation requirements at the time of Order/Permit reissuance, 12-month average mass emission benchmarks have been established for effluent discharged through Discharge Point 001 (120" outfall). These mass emission benchmarks are not enforceable water quality-based effluent limitations. They may be re-evaluated and revised during the five-year Order/Permit term. ATTACHMENT F- FACT SHEET F-52 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS The mass emission benchmarks (in metric tons per year; MT/yr) for the discharge were re-evaluated using the same procedures as described above in Section V.A of this Fact Sheet for the calculation of the Performance Goals. The concentration-based Performance Goals were calculated using effluent monitoring data from May 2015 through December 2019 and were converted to mass-based Benchmarks using the Discharger's annual average influent flow of 206 MGD projected for 2025. The following equation was used for the calculation of the Mass Emission Benchmarks: Mass Emission Benchmark (MT/yr) = (CPG pg/L) x (Q gal/day) x (3.785 L/gal) x (365 days/yr) x (1 MT/1012 fag) where, CPG: Final performance goal calculated from Section V.A of the fact sheet (fag/L) Q: Annual average influent flow projected for 2025 = 206X106 gal/day Most mass emission benchmarks in this Order/Permit are more stringent due to improved performance by completion of full secondary treatment facilities, the use of more sensitive analytical method with lower minimum levels, implementation of an extensive source control pretreatment program, and decreased discharge flowrate (i.e., the projected average daily influent flow reduced from 274 MGD to 206 MGD). VI. RATIONALE FOR RECEIVING WATER LIMITATIONS A. Surface Water The Ocean Plan and Basin Plan contain numeric and narrative water quality standards applicable to surface waters of California. Water quality objectives include a policy to maintain the high-quality waters pursuant to federal regulations (40 CFR § 131.12) and State Water Board Resolution No. 68-16. Receiving water limitations in the Order/Permit are based on the water quality objectives contained in the Ocean Plan chapters II.B, II.C, II.D, II.E, and II.F. The Ocean Plan was amended in 2018 to revise the bacterial water quality objectives for ocean waters used for water contact recreation, which includes removal of the previously established total coliform objectives and the revised enterococci objectives based on the EPA 2012 Recreational Criteria for marine waters. The previously established fecal coliform objective has been retained as recent epidemiological studies conducted at southern California beaches showed that fecal coliform may be a better indicator of gastrointestinal illness than enterococci during certain types of exposures and environmental conditions. This Order/Permit has established receiving water limitations for bacteria based on these amended objectives in the 2019 Ocean Plan. Bacteria receiving water limitations are necessary to protect human health and the water contact recreation uses of the receiving water. The Santa Ana Water Board and USEPA has determined that bacterial indicator standards for water contact recreation are applied throughout the water column of the Nearshore Zone (i.e., designated REC-1). Based on Chapter ll.B.1 of the Ocean Plan, bacterial indicator standards shall also be maintained throughout the water ATTACHMENT F- FACT SHEET F-53 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS column in the Offshore Zone used for water contact sports, as determined by the Santa Ana Water Board and/or USEPA (i.e., waters designated as REC-1), to assure that the discharge does not pose a threat to water contact recreation. Receiving water limitations for enterococcus density in ocean waters beyond the outer limit of the State of California territorial marine waters are based on CWA section 304(a) water quality criteria (i.e., Recreational Water Quality Criteria). These criteria must be achieved beyond the zone of initial dilution in areas where primary contact recreation, as defined in USEPA guidance, occurs. USEPA describes the "primary contact recreation" use as protective when the potential for ingestion of, or immersion in, water is likely. Activities usually include swimming, water-skiing, skin- diving, surfing, and other activities likely to result in immersion (Water Quality Standards Handbook, EPA-823-B-94-005a, 1994, p. 2-2). The nature and extent of primary contact recreational use in federal waters is recorded and reported during water quality monitoring conducted under the receiving water core monitoring program. B. Groundwater— Not Applicable VII. RATIONALE FOR PROVISIONS A. Standard Provisions Standard Provisions, which apply to all NPDES permits in accordance with 40 CFR § 122.41, and additional conditions applicable to specified categories of permits in accordance with 40 CFR § 122.42, are provided in Attachment D of this Order/Permit. 40 CFR § 122.41(a)(1) and (b) through (n) establish conditions that apply to all State- issued NPDES permits. The Order/Permit also incorporates federal conditions that address enforcement authority specified in 40 CFR § 122.41(a)(2) and (3). These conditions must be incorporated into the permits either expressly or by reference. If incorporated by reference, a specific citation to the regulations must be included in the Order/Permit. 40 CFR § 123.25(a)(12) allows the state to omit or modify conditions to impose more stringent requirements. In accordance with 40 CFR § 123.25, this Order/Permit omits federal conditions that address enforcement authority specified in 40 CFR § 122.41(j)(5) and (k)(2) because the enforcement authority under the Water Code is more stringent. In lieu of these conditions, this Order/Permit incorporates by reference Water Code section 13387(e). B. Special Provisions 1. Reopener Provisions The reopener provisions are based on 40 CFR 122.44(c) and 40 CFR § 123.25. The Santa Ana Water Board and USEPA may reopen the Order/Permit to modify conditions and requirements for cause. Causes for modification can include, but are not limited to, the promulgation of new regulations, modification in sludge use or disposal practices, or adoption of new regulations by the State Water Board, ATTACHMENT F- FACT SHEET F-54 ORANGE COUNTY SANITATION DISTRICT ORDER NO.

Southern California Bight Monitoring Exchange The MRP (Attachment E) may be modified by the Santa Ana Water Board and USEPA to enable the Discharger to participate in comprehensive regional monitoring activities conducted in the Southern California Bight during the term of this permit. The intent of regional monitoring activities is to maximize the efforts of all monitoring partners using a cost-effective monitoring design and to best utilize the pooled scientific resources of the region. During these coordinated monitoring efforts, the Discharger's sampling and analytical effort may be reallocated to provide a regional assessment of the impact of wastewater discharges to the Southern California Bight; however, certain core elements (i.e., monthly water quality monitoring, quarterly REC-1 water quality monitoring, quarterly benthic monitoring, semi-annual trawl fish monitoring, and weekly Orange County Regional Shoreline REC-1 cooperative monitoring) shall remain unchanged. Anticipated modifications to the monitoring program will be coordinated so as to provide a comprehensive picture of the ecological and statistical significance of monitoring results and to determine cumulative impacts of various pollutant sources. If predictable relationships among the biological, water quality and effluent monitoring variables can be demonstrated, it may be appropriate to decrease the Discharger's monitoring effort. Conversely, the monitoring program may be intensified if it appears that the objectives cannot be achieved through the Discharger's existing monitoring program. These changes will improve the overall effectiveness of monitoring in the Southern California Bight. Minor changes may be made without further public notice. 3. Special Studies, Technical Reports, and Additional Monitoring Requirements a. Toxicity Reduction Requirements This Order/Permit requires the Discharger to develop procedures to conduct Toxicity Identification and Reduction Evaluations. This provision is based on Chapter III.C.10 of the Ocean Plan. If the discharge consistently exceeds an effluent limitation for toxicity as specified in this Order/Permit, the Discharger shall conduct a Toxicity Reduction Evaluation (TRE) as detailed in section VII.C.3.a of the Order/Permit. The THE will help the Discharger identify the possible source(s) of toxicity. Once the source(s) of toxicity is identified, the Discharger shall take all reasonable steps to reduce toxicity to the required level. b. Dilution Model Update This Permit/Order requires the Discharger to complete an updated dilution analysis for all outfalls as part of its permit application for the next permit reissuance. The Discharger shall update its dilution modeling that is reflective of the future operations upon completion of the GWRS final expansion ATTACHMENT F- FACT SHEET F-55 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS project, which includes, but not limited to the increase in RO concentrate and density and lower discharge flow rate. The updated dilution analysis must continue to use near-field modeling to consider how the effluent plumes behave in the zone of initial dilution (ZID) and demonstrate the impacts of final GWRS expansion to dilution under a "reasonable worst-case scenario" (e.g., critical stratification condition). c. Ocean Outfall Condition Assessment and Scoping Study As the 120-inch outfall approaches the end of life in 2021 , the Discharger is undertaking a condition assessment of the 120-inch ocean outfall (referred to as PS18-09). The project includes removal of accumulated biofouling (i.e., barnacle collar) surrounding the 504 diffuser ports, removal/replacement of manhole covers, the full-length underwater interior inspection of the 120-inch outfall pipe, 3-D scanning and modeling, and analysis of low flow impacts on the diffuser functionality. The first field activity for the 120" inch outfall assessment project (i.e., removal of the barnacles from the outfall ports) was started on July 20, 2020 after the receipt of the Army Corp. of Engineers' permit. OC San also plans to conduct a similar study for Discharge Point 002 (78" outfall) using lessons learned from this 120" outfall condition assessment and scoping study. Upon completion of each outfall condition assessment project, a summary report of the field work findings, including videographic and/or photographic record of the interior of the outfall, 3-D mapping, and any environmental impacts caused during the field works shall be submitted to the Santa Ana Water Board and USEPA. In addition, a separate analysis report of the impacts of low flows on diffuser hydraulics and plugging shall be provided. 4. Best Management Practices and Pollution Prevention a. Pollution Minimization Program This provision is based on the requirements of Chapter III.C.9 of the 2019 Ocean Plan. The goal of the Pollutant Minimization Program is to reduce all potential sources of a pollutant through pollutant minimization strategies, including pollution prevention measures, in order to maintain the effluent concentration at or below the effluent limitation. b. Storm Water Management Plan This Order/Permit requires the Discharger to update its Storm Water Management Plan to implement the 2015 trash amendments of the Ocean Plan. 5. Construction, Operation, and Maintenance Specifications This provision is based on the requirements of 40 CFR §122.41(e) and the previous Order/Permit. a. Roster of Personnel ATTACHMENT F- FACT SHEET F-56 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO.

Operation and Maintenance Manual This Order/Permit requires the Discharger to update an Operation and Maintenance Manual prior to start of operations and specifies its periodic updates. c. Spill Preventive and Contingency Plan (SPCP) Since spills or overflows are a common event at the POTW, this Order/Permit requires the Discharger to review and update, if necessary, its SPCP whenever there is a change which materially affects the potential for spills or after each incident. The Discharger shall ensure that the up-to-date SPCP is readily available to the sewage system personnel at all times and that the sewage personnel are familiar with it. 6. Special Provisions for Publicly-Owned Treatment Works (POTWs) a. Biosolids To implement CWA section 405(d), on February 19, 1993, USEPA promulgated 40 CFR § 503 to regulate the use and disposal of municipal sewage sludge. This regulation was amended on September 3, 1999. The regulation requires that producers of sewage sludge meet certain reporting, handling, and disposal requirements. It is the responsibility of the Discharger to comply with said regulations that are enforceable by USEPA, because California has not been delegated the authority to implement this biosolid program. b. Pretreatment This Order/Permit contains pretreatment requirements consistent with applicable effluent limitations, national standards of performance, and toxic and performance effluent standards established pursuant to Sections 208(b), 301 , 302, 303(d), 304, 306, 307, 403, 404, 405, and 501 of the CWA, and amendments thereto. This permit contains requirements for the implementation of an effective pretreatment program pursuant to Section 307 of the CWA; 40 CFR § 35 and 403; and/or Section 2233, Title 23, California Code of Regulations. c. Collection System The State Water Board issued General Waste Discharge Requirements for Sanitary Sewer Systems, Water Quality Order 2006-0003-DWQ (General Order) on May 2, 2006. The State Water Board amended the Monitoring and Reporting Program for the General Order through Order WQ 2013-0058- EXEC on August 6, 2013. The General Order requires public agencies that own or operate sanitary sewer systems with sewer lines one mile of pipe or greater to enroll for coverage and comply with the General Order. The General Order requires agencies to develop sanitary sewer management ATTACHMENT F- FACT SHEET F-57 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS plans and report all sanitary sewer overflows, among other requirements and prohibitions. The General Order contains requirements for operation and maintenance of collection systems and for reporting and mitigating sanitary sewer overflows that are more extensive, and therefore, more stringent than the requirements under federal standard provisions. The Discharger and public agencies that are discharging wastewater into the facility's collection system were required to obtain enrollment for regulation under the General Order by December 1, 2006. d. Resource Recovery from Anaerobically Digestible Material. Some POTWs choose to accept organic material such as food waste, fats, oils, and grease into their anaerobic digesters for co-digestion to increase production of methane and other biogases for energy production and to prevent such materials from being discharged into the collection system, which could cause sanitary sewer overflows. The California Department of Resources Recycling and Recovery has proposed an exemption from requiring Process Facility/Transfer Station permits where this activity is regulated under waste discharge requirements or NPDES permits. The proposed exemption is restricted to anaerobically digestible material that has been prescreened, slurried, and processed/conveyed in a closed system to be co-digested with regular POTW sludge. The proposed exemption requires that a POTW develop Standard Operating Procedures for the proper handling, processing, tracking, and management of the anaerobically digestible material before it is received by the POTW. Standard Operating Procedures are required for POTWs that accept hauled food waste, fats, oil, and grease for injection into anaerobic digesters. The development and implementation of Standard Operating Procedures for management of these materials is intended to allow the California Department of Resources Recycling and Recovery to exempt this activity from separate and redundant permitting programs. If the POTW does not accept food waste, fats, oil, or grease for resource recovery purposes, it is not required to develop and implement Standard Operating Procedures. e. Ensuring Adequate Treatment Capacity The Discharger shall submit a written report to the Santa Ana Water Board and USEPA within 90 days after the monthly average influent flow rate equals or exceeds 75 percent of the secondary design capacity of the POTW to prevent the waste flow exceeding the capacity of the POTW. f. Asset Management This Order/Permit requires the Discharger to develop an asset management program to cover the POTW. 7. Other Special Provisions ATTACHMENT F- FACT SHEET F-58 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS a. Monitoring Data Accessibility This Order/Permit requires the Discharge to make monitoring data accessible to the public via the internet. 8. Compliance Schedules — Not Applicable Vill. RATIONALE FOR MONITORING AND REPORTING REQUIREMENTS CWA section 308 and 40 CFR § 122.41(h), 0)-(1), 122.44(i), and 122.48 require that all NPDES permits specify monitoring and reporting requirements. California Water Code sections 13267 and 13383 also authorize the Santa Ana Water Board to establish monitoring, inspection, entry, reporting, and recordkeeping requirements. The Monitoring and Reporting Program (MRP), Attachment E of this Order establishes monitoring, reporting, and recordkeeping requirements that implement federal and state requirements. The following provides the rationale for the monitoring and reporting requirements contained in the MRP for this facility. The MRP is guided, in part, by the principals, framework, and recommended design for discharge and receiving water monitoring presented in the Ocean Plan and Model Monitoring Program for Large Ocean Dischargers in Southern California (SCCWRP Tech. Rep. #357. Southern California Coastal Water Research Project, Westminster, CA. 2002). The conceptual framework for the MRP has three components that comprise a range of spatial and temporal scales: (1) core monitoring, (2) regional monitoring, and (3) strategic process studies. Core Monitoring. Core monitoring is local in nature and focuses on monitoring trends in quality and effects of the point source discharge. This includes effluent monitoring, as well as many aspects of receiving water monitoring. Regional Monitoring. Regional monitoring is focused on questions best answered by a region-wide approach that incorporates coordinated survey design and sampling techniques. Key components of regional monitoring include elements to address pollutant mass emission estimates, public health concerns, monitoring trends in natural resources, assessment of regional impacts from all contaminant sources, and beneficial use protection. The final designs of regional monitoring programs are developed by means of steering and technical committees comprised of participating agencies and organizations. For each component of regional monitoring, the MRP specifies the required degree and nature of participation by the Discharger, based upon its past participation in regional monitoring programs. Strategic Process Studies. Strategic process studies are focused on refined questions regarding specific effects or development of monitoring techniques and are anticipated to be of short duration and/or small scale, although multi-year studies also may be needed. Questions regarding discharge or receiving water quality, discharge impacts, ocean processes in the area of the discharge, or development of techniques for monitoring the same, arising out of the results of core or regional monitoring, may be pursued through strategic process studies. These studies are by nature ad hoc and, typically, cannot be typically anticipated in advance of the five-year permit cycle. ATTACHMENT F- FACT SHEET F-59 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS A. Influent Monitoring Influent monitoring is required to determine compliance with effluent limitations and permit conditions, assess the performance of treatment facilities and evaluate the effectiveness of pretreatment and nonindustrial source control programs. Influent monitoring in this Order/Permit follows the influent monitoring requirements in the previous Order/Permit with minor changes. The sample type and monitoring frequencies for halomethanes and 1,4-Dichlorobenzene were changed to grab and 1/quarter, respectively, to be consistent with other volatiles constituents. The monitoring frequency for ammonia nitrogen has been changed to weekly for proper self-monitoring as scheduled in Table E-16. The monitoring requirements for tributyltin and TCDD equivalents have been included. B. Effluent Monitoring Effluent monitoring is required to determine compliance with effluent limitations and permit conditions, and to identify operational problems and improve treatment facility performance. Effluent monitoring also provides information on discharge characteristics and flows for use in interpreting receiving water monitoring data. Effluent monitoring requirements also addresses the three management questions for effluent monitoring in Model Monitoring Program for Large Ocean Discharges in Southern California (SCCWRP, 2002; Model Monitoring Program): Is the effluent concentration of selected constituents below levels that will protect human health and aquatic life? What is the mass of selected constituents that are discharged annually? Is the effluent concentration or mass changing over time? Noteworthy changes for this Order/Permit include removal of total coliform monitoring at Discharge Point 002 (78" outfall) due to new bacteria water quality objectives in the 2019 Ocean Plan, more frequent monitoring for nutrient parameters, addition of annual monitoring for total nitrogen and quarterly monitoring for tributyltin, changes in monitoring frequencies for ammonia nitrogen for proper self-monitoring as scheduled in Table E-16, and changes in the sample type and/or monitoring frequencies for halomethanes and 1,4-Dichlorobenzene to be consistent with other volatile constituents. In addition, effluent monitoring stations have been defined separately, for the effluent discharged to Discharge Point 001 during normal operations as EFF-001 and to Discharge Point 002 during planned essential maintenance or capital improvement projects as EFF-002, in order to determine compliance with each permit limitation and requirement. C. Whole Effluent Toxicity Testing Requirements The rationale for WET has been discussed extensively in Section IV.C.5. of this Fact Sheet. Noteworthy WET changes for this Order/Permit include WET testing for Discharge Point 002 (78" outfall) using the TST hypothesis testing approach instead of ATTACHMENT F- FACT SHEET F-60 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS NOEC statistical approach. This TST statistical approach is consistent with the Ocean Plan in that it provides maximum protection to the environment since it more reliably identifies chronic toxicity than the previous NOEC hypothesis-testing approach. D. Receiving Water Core Monitoring To evaluate potential environmental and human health impacts from its discharge of final effluent into the Pacific Ocean, the Discharger conducts extensive water quality, sediment quality, fish and invertebrate community, and fish health monitoring off the coastal cities of Newport Beach and Huntington Beach, California. 1. Water Quality Monitoring Offshore water quality monitoring data are used to determine compliance with receiving water limitations and Ocean Plan objectives for physical and chemical parameters, and assist in the interpretation of biological data. Water quality data collected provide the information necessary to demonstrate compliance with the water quality standards. Water quality monitoring requirements also addresses the two management questions for water quality monitoring in the Model Monitoring Program: Are water column physical and chemical parameters within ranges that ensure protection of the ecosystem? What is the fate of the discharge plume? Monthly water quality monitoring will be carried out over a large grid of 28 stations centered on Discharge Point 001 (120" outfall). The station grid covers from the coastline of Huntington Beach to Newport Beach. Noteworthy changes for this Order/Permit include the addition of monthly monitoring for nitrate nitrogen to further investigate nutrients driving ocean acidification and the relationship between nutrients discharged through Discharge Point 001 (120" outfall) and harmful algal blooms. 2. REC-1 Water Quality Monitoring (Offshore Zone) This REC-1 water quality monitoring is designed to determine if Ocean Plan water quality objectives for physical and chemical parameters and bacteria are being met. Data collected at these REC-1 monitoring stations provide the means to determine whether water quality standard and bacteriological objectives for water contact are being met. REC-1 monitoring requirements also addresses the two management questions for REC-1 monitoring in the Model Monitoring Program: Does sewage effluent reach water contact zones? Are densities of bacteria in water contact zones below levels that will ensure public safety? Quarterly (5-days/30-day period), REC-1 monitoring will be carried out over a picket-line of the 8 stations centered inshore of Discharge Point 001 (120" ATTACHMENT F- FACT SHEET F-61 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS outfall), in State waters. The south-to-north station alignment is adjacent to the coastline of Huntington Beach and Newport Beach. 3. Sediment Monitoring The purpose of sediment monitoring is to map the area of impact and detect spatial and temporal trends in sediment pollutants and benthic infauna in the area of the discharge, and to assess compliance with State water quality standards and federal criteria. The data collected are used for regular assessment of trends in sediment contamination and biological response along a fixed grid of sites within the influence of the discharge. Sediment monitoring requirements also addresses the two management questions for sediment monitoring in the Model Monitoring Program: Are sediments in the vicinity of the discharge impaired? If so, what is the spatial extent of impairment? Are sediment conditions changing over time? The previous benthic sampling grid consisted of 29 semi-annual monitoring stations and 39 annual monitoring stations. The previous semi-annual station array is based on a sediment mapping study conducted by the Southern California Coastal Water Research Project (SCCWRP) from 2009 to 2012. This study recommended the design to best capture changes in sediment quality resulting from the effluent discharge. The investigation into changes in benthic community health as a result of the District's effluent disinfection with chlorine bleach (Changes in Biological Communities near the OCSD Outfall, OCSD Marine Monitoring, 2013) revealed that impacts to benthic communities were localized to stations at and near (< 1 km) the 120" outfall diffuser. Impacts were seen at Stations 0, 1, 3, 4, 9, 84, 85, 86, 87, and ZB. All other stations were unaffected even though the degree of impact was severe at near outfall stations. Based on these results and over three decades of monitoring data, a more effective and efficient sediment monitoring station design has been constructed in this Order/Permit as below: a. Quarterly sampling for sediment chemistry and benthic infauna at 11 stations immediately surrounding the 120" outfall diffuser along the 60-meter contour line, including 3 stations within the ZID boundaries. (Note that these quarterly monitoring stations were the first and the most severely impacted stations by effluent chlorination.) b. Annual whole sediment toxicity sampling at the 11 quarterly monitoring stations. c. Annual (summer) sampling for sediment chemistry and benthic infauna at 11 stations located near the outfall and extending northward and southward along the 60-meter contour line. ATTACHMENT F- FACT SHEET F-62 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS d. Once per 5 year (1/5-year) sampling for sediment chemistry and benthic infauna at an additional 35 stations centered on Discharge Point 001 (120" outfall) from Huntington Beach to Newport Beach coastlines. Stations 68, 69, 70,71 , 72, 79, 80, 81, and 82 were eliminated as they are redundant to the station design. Downcoast Station C2 and farfield upcoast Station C were also removed as the sediment quality and biological community at these stations have been consistently different from those of other 60 m stations including control station, considering outliers. Therefore, total number of stations is reduced from 68 stations to 57 stations. The reduction in taxonomic and sediment geochemical analyses would enable the Discharger to redirect its efforts toward SPS and special studies to evaluate potential environmental impacts related to increased wastewater reclamation efforts and investigate CEC identification and characterization in effluent and sediments and toward the regional monitoring programs including Bight 18. With the new sediment monitoring design, the number of stations sampled annually in summer is reduced from 68 to 22, which can reduce the turn-around time for summer data from approximately 9 to 12 months to 3 months, especially for the 11 quarterly stations in all seasons. This will provide a rapid assessment of sediment conditions and a more rapid response to changes in sediment quality and/or benthic infauna community within the monitoring area. Noteworthy changes for this Order/Permit also include the change in sampling frequency for 35 monitoring stations that previously sampled annually to one-off (i.e., once per 5 years) since these stations are either not directly or not significantly impacted by the effluent discharge. Three (3) stations (i.e., Stations 10, 13, and 37) at the 60-m contour line remains as annual monitoring stations. Sampling these 1/5-year monitoring stations allows long-term trend analysis to continue in these areas where change occurs much more slowly in response to changes in effluent quality than at the outfall diffuser. 4. Demersal Fish and Epibenthic Macroinvertebrate Monitoring The purpose of demersal fish and epibenthic macroinvertebrate monitoring is to detect spatial and temporal trends in demersal fish and epibenthic community structure, demersal fish liver tissue chemistry and liver histopathology, and sport fish muscle tissue chemistry in the area of the discharge, and to assess compliance with State water quality standards and federal criteria. The demersal fish and epibenthic macroinvertebrate monitoring data collected are used for regular assessment of temporal trends in community structure along an array of sites within the influence of the discharge. The sport fish monitoring data collected are used to provide information necessary for the management of local seafood consumption advisories. Demersal fish and epibenthic invertebrate monitoring requirements also address the four management questions for fish and epibenthic invertebrate monitoring and seafood safety monitoring in the Model Monitoring Program: ATTACHMENT F- FACT SHEET F-63 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS Is the health of fish populations and communities impaired? Are fish populations and communities changing over time? Is fish tissue contamination changing over time? Are seafood tissue concentrations below levels that will ensure public safety? Annual demersal fish and epibenthic community monitoring continues to be carried out over a grid of 14 stations upcoast of Discharge Point 001 (120" outfall); of these 14 stations, the 6 stations at the outfall depth (60 meters) are monitored semi-annually. The monitoring area covers approximately 27 square kilometers adjacent to the coastline of Huntington Beach and Newport Beach. Annual demersal fish tissue chemistry monitoring is carried out over two stations upcoast of Discharge Point 001 at the outfall depth. Annual sport fish muscle tissue chemistry monitoring is also conducted in summer at two zones. Noteworthy changes for this Order/Permit are listed below: a. Target fish species. For demersal fish and epibenthic community monitoring, the previous Order/Permit required at least 10 individuals of each target species (i.e., Hornyhead Turbot and English Sole) per station. This Order/Permit allows the Discharger to collect 20 individuals total of flat fish (e.g., Pacific Sanddab, Hornyhead Turbot and English Sole) per station. For sport fish monitoring, the Discharger can collect 10 individuals total of rockfish (e.g., Vermilion Rockfish, Copper Rockfish, and California Scorpionfish) at each rig fish monitoring zone. Kelp bass and Sandbass are removed from the target species list in this Order/Permit because none of these fishes was caught by the Discharger at any of the three rig fishing zones in the past three monitoring periods (2014 — 2016). b. Demersal fish tissue chemistry monitoring - Target tissue. The previous Order/Permit required sampling and analysis of both fish liver and muscle tissues in Hornyhead Turbot and English Sole for the assessment of predator wildlife risk by consuming these two target fish species. Noteworthy change in demersal fish tissue chemistry monitoring for this Order/Permit includes removal of muscle tissue and analysis of contaminants in fish liver tissue only. The concentration of contaminants in demersal fish muscle tissue were relatively negligible for two permit cycles compared with liver tissues, given that liver tissue has higher lipid content than muscle tissue and therefore can bioaccumulate higher concentrations of lipid-soluble contaminants such as PCBs and DDT. It stands to reason that when this demersal fish is consumed whole by a fish predator, it is likely that the predator will acquire considerably higher contaminant loads from liver tissue as compared to muscle tissue, rendering the muscle tissue analysis dispensable. c. Chemical analysis changes — Composite sampling. To monitor bioaccumulation of organic contaminants (i.e., PCBs, DDT, and Chlordane) and metals (i.e., Arsenic, Selenium, and Mercury) in either demersal fish liver tissue or sport fish muscle tissue, composite samples of target fish will be ATTACHMENT F- FACT SHEET F-64 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS analyzed instead of individual sample analysis. This composite tissue analysis can minimize the variation between contaminant measurements, increase the ability to detect target compounds that are present in low concentrations, and improve the representativeness of the contaminant measurements at each sampling site, which is also consistent with fish tissue analysis protocols of other POTW ocean monitoring programs within the Southern California Bight. d. Monitoring frequency of demersal fish liver histopathology. Liver histopathology will be conducted on an annual basis instead of once every permit cycle to facilitate rapid detection of potential adverse effects on fish health by the anticipated changes in effluent quality and characteristics with GWRS final expansion (e.g., increased RO concentrate flow). Fish liver histopathology was used in the investigation of effluent chlorination effects and was found to be a useful biomarker of impact and the only significant effect on fish health. e. Sport fish monitoring - Farfield reference zone. The Discharger was not able to catch the number of fish samples required by the previous Order/Permit at the farfield reference zone (Zone 2) in two consecutive years (2014 — 2015) after the issuance of the previous 2012 Order/Permit. After consulting with scientists from the California Department of Fish and Wildlife, the reference zone was relocated to an area near the Huntington Beach oil rigs (Zone 3) as this site only met the species and number of fish requirements among several candidate sites. In this Order/Permit, Zone 2 was replaced with Zone 3 as a farfield reference zone. E. Receiving Water Regional Monitoring Discharger participation in regional monitoring programs continues to be a required condition of the Order/Permit. Regional monitoring programs which must be conducted under the Order/Permit include: Southern California Bight Regional Monitoring Program, Southern California Bight Regional Water Quality Program, Central Regional Kelp Survey, Orange County Regional Shoreline REC-1 Cooperative Monitoring Program, and Ocean Acidification and Hypoxia (OAH) Mooring. The Discharger currently participates in all five programs. For the regional monitoring program, collaboration with other water sectors (e.g., water supply, wastewater, groundwater, and stormwater) is encouraged to evaluate implementation of integrated water resource projects that helps achieve sustainable integrated water resources management. Noteworthy changes for the Southern California Bight Regional Water Quality Program under this Order/Permit include the addition of four field sampling surveys per year, removal of stations transects 2021, 2181, 2221, and 2349 for more equal spacing of transects, and creation of transect lines 1701, 1801 , and 2041 to extend sampling downcoast to Dana Point.

The number of Orange County Regional Shoreline REC-1 Cooperative Monitoring Program stations has been changed from 38 to 36 due to removal of two Stations (i.e., OSB02 and ELMORO) at the request of the Orange County Health Care Agency. F. Strategic Process Studies Discharger investigations conducted through strategic process studies continues to be a required condition of the Order/Permit. Strategic process studies which must be conducted under the Order/Permit include: ROMS-BEC Ocean Outfall Modeling, Microplastics Characterization, Contaminants of Emerging Concern Monitoring, Sediment Linear Alkylbenzenes, and Meiofauna Baseline. These studies have been approved by the Santa Ana Water Board and USEPA during the term of the 2012 Order/Permit but not yet completed by the Discharger. Additional studies will be proposed over the next permit cycle to ascertain if GWRS final expansion, which will result in lower outfall flows and higher concentration of the final effluent due to RO reject flow, will result in deleterious environmental impacts. G. Other Monitoring Requirements 1. Contaminants of Emerging Concern (CEC) Monitoring Study The Discharger shall continue to investigate CECs identification and characterization in the final effluent, listed in Table E-15 of the MRP (Attachment E). The Discharger has annually screened for 15 pharmaceuticals and personal care products (PPCPs), 7 hormones, 7 industrial endocrine disrupting compounds (IEDCs), and 9 flame retardants in the final effluent in the previous permit. In addition, this Order/Permit requires the Discharger to conduct monitoring for new CECs of 6 pesticides and insecticides (i.e., Fipronil, Fipronil Sulfone, Bifenthrin, Total Permethrin, Chlorpyrifos, and Diazinon), 3 flame ATTACHMENT F— FACT SHEET F-66 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS retardants (i.e., TDCPP, TCEP, and TCPP) and 12 per- and polyfluoroalkyl substances (PFAS) compounds. With regard to PFAS compounds, POTWs are potentially significant receivers of PFAS from various sources, including disposal of landfill leachate and firefighting foam, results in PFAS in the influent to POTWs. Typical POTW treatment systems are not designed to remove PFAS, and therefore, the discharge from POTWs, especially those with industrial inputs, are possible contributors of PFAS to the surface waters. Based on the State Water Board's PFAS analytical data obtained from PFAS Investigative Orders, 12 PFAS compounds (i.e., PFDA, PFDoA, PFNA, PFHxA, PFHpA, PFDA, PFTA, PFTrDA, PFUnA, PFBS, PFHxS, and PFOS) are included in this Order/Permit to identify and understand PFAS in wastewater. 2. Outfall and Diffuser System Inspection This survey investigates the condition of the outfall structures to determine if the structures are in serviceable condition to ensure their continued safe operation. The inspection frequency has been increased to twice per permit term as the 120-inch outfall approaches the end of life in 2021. The data collected will be used for a periodic assessment of the integrity of the outfall pipes and diffuser system. 3. Discharge Monitoring Report-Quality Assurance (DMR-QA) Study Program Under the authority of section 308 of the CWA (33 U.S.C. § 1318), USEPA requires major and selected minor dischargers under the NPDES Program to participate in the annual DMR-QA Study Program. The DMR-QA Study evaluates the analytical ability of laboratories that routinely perform or support self- monitoring analyses required by NPDES permits. There are two options to satisfy the requirements of the DMR-QA Study Program: (1) The Discharger can obtain and analyze a DMR-QA sample as part of the DMR-QA Study; or (2) Per the waiver issued by USEPA to the State Water Board, the Discharger can submit the results of the most recent Water Pollution Performance Evaluation Study from its own laboratories or its contract laboratories. A Water Pollution Performance Evaluation Study is similar to the DMR-QA Study. Thus, it also evaluates a laboratory's ability to analyze wastewater samples to produce quality data that ensure the integrity of the NPDES Program. The Discharger shall ensure that the results of the DMR-QA Study or the results of the most recent Water Pollution Performance Evaluation Study are submitted annually to the State Water Board. The State Water Board's Quality Assurance Program Officer will send the DMR- QA Study results or the results of the most recent Water Pollution Performance Evaluation Study to USEPA's DMR-QA Coordinator and Quality Assurance Manager. IX. PUBLIC PARTICIPATION The Santa Ana Water Board and USEPA have considered the issuance of WDRs and an NPDES permit for OC San.

FACILITY INFORMATION Information describing the Orange County Sanitation District (hereinafter "OC San", "Permittee" or "Discharger") is summarized in Tables 1 and 2, and in sections I and II of the Fact Sheet (Attachment F). Section I of the Fact Sheet also includes information regarding the Facility's permit application. II. FINDINGS The California Regional Water Quality Control Board, Santa Ana Region (hereinafter "Santa Ana Water Board") and the United States Environmental Protection Agency, Region 9 (hereinafter "USEPA") find: A. Legal Authorities. This Order serves as waste discharge requirements (WDRs) pursuant to article 4, chapter 4, division 7 of the California Water Code (CWC; commencing with section 13260). This Order is also issued pursuant to section 402 of the federal Clean Water Act (CWA) (Public Law 92-500, as amended, 33 U.S.C. 1251 et seq.) and implementing regulations adopted by USEPA and chapter 5.5, division 7 of the CWC (commencing with section 13370). It shall serve as the State's National Pollutant Discharge Elimination System (NPDES) permit authorizing the Discharger to discharge into waters of the United States at the discharge locations described in Table 2, subject to the WDRs in this Order (hereinafter "Order"). The Order/Permit are consolidated under 40 CFR § 124.4(c)(2). Although Discharge Point 001 is beyond the limit of State-regulated ocean waters, effluent plume migration into State waters warrants joint regulation of the discharge by USEPA and the Santa Ana Water Board. Therefore, pursuant to 40 CFR § 124.4, this Order shall serve as a joint consolidated State and federal NPDES Permit authorizing the Discharger to discharge into waters of the United States at the discharge locations described in Table 2, subject to the limitations, conditions and all other requirements set forth herein (hereinafter "Order/Permit"). The Permit is both a federal permit and a state permit by operation of law. B. Background and Rationale for Requirements. The Santa Ana Water Board and USEPA developed the requirements in this Order/Permit based on information submitted as part of the application, through monitoring and reporting programs, and other available information. The Fact Sheet (Attachment F), which contains background information and rationale for the requirements in this Order/Permit, is hereby incorporated into and constitutes Findings for this Order/Permit. Attachments A through E and G though H are also incorporated into this Order/Permit. C. Permit Renewal Contingency. The Discharger's federal NPDES Permit renewal is contingent upon: 1. Determination by the U.S. Fish and Wildlife Service (USFWS) and the National Oceanic and Atmospheric Administration (NOAA) National Marine Fisheries Service (NMFS) that the discharge is consistent with the federal Endangered Species Act (ESA) of 1973, as amended (16 U.S. Code (U.S.C.) section 1531 et seq.); WASTE DISCHARGE REQUIREMENTS AND NPDES PERMIT 7 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS 2.

G. Discharge at Discharge Point 001 (120" outfall) is prohibited when the discharge does not receive a minimum initial dilution of at least 181:1 (Dm = 180), as modeled assuming no currents. Compliance shall be achieved by proper operation and maintenance of the discharge outfall to ensure that it (or its replacement, in whole or part) is in good working order and is consistent with, or can achieve better mixing than, 181:1. The Discharger shall notify the Santa Ana Water Board and USEPA if outfall ports will be retrofitted, as the 181:1 dilution assumes all outfall ports are operational. H. Unless regulated by appropriate waste discharge requirements, the discharge to surface or groundwaters of waste which contains the following substances is prohibited: toxic substances or materials; pesticides; PCBs (polychlorinated biphenyls); mercury or mercury compounds; radioactive substances or material in excess of levels allowed by the California Code of Regulations. This list is not necessarily all-inclusive. I. The discharge of untreated sewage to any surface water stream, natural or man-made, or to any drainage system intended to convey storm water runoff to surface water streams is prohibited. J. The discharge of treated sewage to streams, lakes or reservoirs, or to tributaries thereto, which are designated MUN and which are used as a domestic water supply is prohibited unless approved by the California Department of Public Health. The discharge of treated sewage to waterbodies which are excepted from MUN (Basin Plan Table 3-1) but which are tributary to waters designated MUN and are used as a domestic water supply is prohibited unless the discharge of treated sewage to the drinking water supply is precluded or approved by the California Department of Public Health. K. The discharge of wastewater to a water of the United States from any locations other than Discharge Point 001 (120" outfall) is prohibited, except during the following situations: 1. Emergency discharge of disinfected secondary effluent and/or reverse osmosis (RO) concentrate to Discharge Point 002 (78" outfall) when the flow rate exceeds the hydraulic capacity of Discharge Point 001, provided that discharges through Discharge Point 001 (120" outfall) and discharges to Orange County Water District (OCWD)'s water recycling facilities are maximized to a functional capacity that is necessary to prevent infrastructure or equipment damage before wastewater is discharged through Discharge Point 002; 2. Emergency discharge of disinfected secondary effluent and/or RO concentrate to Discharge Point 003 (Santa Ana River overflow weirs) in the event of an extreme emergency (e.g., tsunami, earthquake, flood, and acts of war or terrorism) that precludes discharging all wastewater to Discharge Points 001 and 002, provided that discharges through Discharge Points 001 (120" outfall) and 002 (78" outfall) are maximized before wastewater is discharged through Discharge Point 003; or WASTE DISCHARGE REQUIREMENTS AND NPDES PERMIT 9 ORANGE COUNTY SANITATION DISTRICT ORDER NO.

Discharge of disinfected secondary effluent and/or RO concentrate to Discharge Point 002 (78" outfall) during planned essential maintenance or capital improvement projects to assure efficient operation of Discharge Point 001 (120" outfall) when there is no other feasible alternative. The Santa Ana Water Board Executive Officer and USEPA Water Division Director are notified of the pending discharge as soon as possible. During a planned diversion such as essential maintenance or capital improvement projects, this notification shall be submitted a minimum of 10 days prior to diverting flow to Discharge Point 002 (78" outfall), and include the rationale for the discharge, the expected time, date, and the duration of the discharge. Projects warranting such a diversion must be approved by the Santa Ana Water Board Executive Officer and USEPA Water Division Director prior to diverting flow to Discharge Point 002. The Discharger shall take all steps required by the Santa Ana Water Board Executive Officer or USEPA Water Division Director to minimize any harm resulting from the discharge. IV. EFFLUENT LIMITATIONS AND DISCHARGE SPECIFICATIONS A. Discharge Specifications — Discharge Points 001 and 002 1. Waste management systems that discharge to the ocean must be designed and operated in a manner that will maintain the indigenous marine life and a healthy and diverse marine community. 2. Waste discharged to the ocean must be essentially free of: Material that is floatable or will become floatable upon discharge; settleable material or substances that may form sediments which will degrade benthic communities or other aquatic life; substances which will accumulate to toxic levels in marine waters, sediments or biota; substances that significantly decrease the natural light to benthic communities and other marine life; and materials that result in aesthetically undesirable discoloration of the ocean surface. 3. Waste effluents shall be discharged in a manner which provides sufficient initial dilution (Dm = 180 for Discharge Point 001 and Dm = 36 for Discharge Point 002), with exception of radioactivity, to minimize the concentrations of substances not removed in the treatment. 4. Waste that contains pathogenic organisms or viruses should be discharged a sufficient distance from naturally occurring shellfishing and water contact sports are to maintain applicable bacterial standards without disinfection. Where conditions are such that an adequate distance cannot be attained, reliable disinfection in conjunction with a reasonable separation of the discharge point from the area of use must be provided. Disinfection procedures at Discharge Point 002 (78" outfall) that do not increase effluent toxicity and that constitute the least environmental and human hazard should be used. B.

The performance goals are not considered enforceable effluent limitations or standards for the regulation of discharge from the treatment facility. The Discharger shall maintain existing treatment levels and the effluent quality at or below the performance goal concentrations. Any two consecutive exceedances of the performance goals shall trigger an investigation into the cause of the exceedance. If the exceedance persists in three successive monitoring periods, the Discharger shall submit a written report to the Santa Ana Water Board and USEPA on the nature of the exceedance, the results of the investigation including the cause of the exceedance. The Santa Ana Water Board and USEPA may reopen the Order/Permit to modify any of the performance goals if the Discharger submits a request and demonstrates that the change is warranted, including results of completion of GWRS final expansion. B. Mass Emission Benchmarks — Discharge point 001 The following 12-month average mass emission benchmarks for Discharge Point 001 (120" outfall) are prescribed below in Table 7. For each parameter with a mass emission benchmark, the Discharger shall report the annual mass emission and the effluent concentrations and flows used to calculate the annual mass emission in the annual pretreatment report and annual receiving water monitoring report (effluent chapter). These mass emission benchmarks are not enforceable water quality-based effluent limitations. They may be re-evaluated and revised during the five-year permit term. For this Order/Permit, the mass emissions benchmarks (in metric tons per year; MT/yr) were determined based on 2015 through 2019 effluent mass emission and the Discharger's annual average influent flow of 206 MGD projected for 2025 (see section V of the fact sheet in Attachment F).

Surface Water Limitations The discharge of waste by the Discharger shall not cause a violation of the California Ocean Plan water quality objectives and USEPA water quality criteria specified below. Compliance shall be determined from samples collected at stations representative of the area within the waste field where initial dilution is completed. 1. Bacterial Characteristics a. State Water Board Water-Contact Objectives i. Within a zone bounded by the shoreline and a distance of 1,000 feet from the shoreline or the 30-foot depth contour, whichever is further from the shoreline, and in areas outside this zone used for water contact sports, as determined by the Santa Ana Water Board or USEPA (i.e., waters designated as REC-1), but including all kelp beds, the following bacterial water quality objectives shall be maintained throughout the water column: Fecal Coliform A 30-day geometric mean of fecal coliform density shall not exceed 200/100 mL, calculated based on the geometric mean of the five most recent samples from each site, and a single sample maximum shall not exceed 400/100 mL. Enterococci A 6-week rolling geometric mean of enterococci, calculated weekly, shall not exceed 30 CFU or MPN per 100 mL. The geometric mean value shall be applied based on a statistically sufficient number of samples, which is generally not less than five samples distributed over a 6-week period.

CA0110604 COLLECTION SYSTEM & OUTFALLS A statistical threshold value of 110 CFU or MPN per 100 mL shall not be exceeded by more than 10 percent of all enterococci samples collected in a calendar month, calculated in a static manner. ii. The Initial Dilution Zone of wastewater outfalls shall be excluded from designation as kelp beds for purposes of bacterial standards. Adventitious assemblages of kelp on waste discharge structures (e.g., outfall pipes and multiport diffusers) do not constitute kelp beds for purposes of bacterial standards. b. State Water Board Beach Notification Levels Minimum protective bacteriological standards for coastal waters adjacent to public beaches and for public water-contact sports areas in ocean waters are established in the California Code of Regulations, Title 17 (beginning at div. 1, ch. 5, section 7958 et seq.), which are not water quality objectives. When a public beach or public water-contact sports area fails to meet these standards, the California Department of Public Health or the local public health officer may post with warning signs or otherwise restrict use of the public beach or public water-contact sports area until the standards are met. The regulations impose more frequent monitoring and more stringent posting and closure requirements on certain high-use public beaches that are located adjacent to a storm drain that flows in the summer. c. State Water Board Shellfish Harvesting Standards At all areas where shellfish may be harvested for human consumption, as determined by the Santa Ana Water Board and USEPA, the following bacterial objectives shall be maintained throughout the water column: The median total coliform density shall not exceed 70 per 100 mL, and not more than 10 percent of the samples shall exceed 230 per 100 mL. d. USEPA Recreational Water Quality Criteria (RWQC) Ocean waters beyond the outer limit of the territorial sea shall not exceed the following RWQC for Enterococcus density beyond the zone of initial dilution in areas where primary contact recreation occurs. The 2012 RWQC describes the criteria are designed to protect "primary contact recreation", including swimming, bathing, surfing, water skiing, tubing, water play by children, and similar water contact activities where a high degree of bodily contact with the water, immersion and ingestion are likely (Recreational Water Quality Criteria, EPA-820-F-12-058, 2012, p. 6.). Estimated illness rate of 32 per 1,000 primary contact recreators: A 30-day geometric mean shall not exceed 30 CFU or MPN per 100 mL, which is calculated based on a statistically sufficient number of samples (generally not less than five samples equally spaced over any 30-day period).

Physical Characteristics a. Floating particulates and grease and oil shall not be visible. b. The discharge of waste shall not cause aesthetically undesirable discoloration of the ocean surface. c. Natural light shall not be significantly reduced at any point outside the initial dilution zone as the result of the discharge of waste. d. The rate of deposition of inert solids and the characteristics of inert solids in ocean sediments shall not be changed such that benthic communities are degraded. e. Trash from the discharge shall not be present in ocean waters, along shorelines or adjacent areas in amounts that adversely affect beneficial uses or cause nuisance. 3. Chemical Characteristics a. The dissolved oxygen concentration shall not at any time be depressed more than 10 percent from that which occurs naturally, as the result of the discharge of oxygen demanding waste materials. b. The pH shall not be changed at any time more than 0.2 units from that which occurs naturally. c. The dissolved sulfide concentration of waters in and near sediments shall not be significantly increased above that present under natural conditions. d. The concentration of substances, set forth in Chapter II, Table 3 of the California Ocean Plan, in marine sediments shall not be increased to levels which would degrade indigenous biota. e. The concentration of organic materials in marine sediments shall not be increased to levels which would degrade marine life. f. Nutrient materials shall not cause objectionable aquatic growths or degrade indigenous biota. g. Numerical water quality objectives established in Table 3 of the California Ocean Plan shall not be exceeded as a result of discharges from the facility through Discharge Points 001 and 002 (as computed using an applicable dilution factor). 4. Biological Characteristics a. Marine communities, including vertebrate, invertebrate, and plant species, shall not be degraded. b. The natural taste, odor, and color of fish, shellfish, or other marine resources used for human consumption shall not be altered.

I. Or as otherwise authorized by law. 2. Southern California Bight Monitoring Exchange The MRP (Attachment E) may be modified by the Santa Ana Water Board and USEPA to enable the Discharger to participate in comprehensive regional monitoring activities conducted in the Southern California Bight during the term of this permit. The intent of regional monitoring activities is to maximize the efforts of all monitoring partners using a cost-effective monitoring design and to best utilize the pooled scientific resources of the region. During these coordinated monitoring efforts, the WASTE DISCHARGE REQUIREMENTS AND NPDES PERMIT 27 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS Discharger's sampling and analytical effort may be reallocated to provide a regional assessment of the impact of wastewater discharges to the Southern California Bight; however, certain core elements (i.e., monthly water quality monitoring, quarterly REC-1 water quality monitoring, quarterly benthic monitoring, semi-annual trawl fish monitoring, and weekly Orange County Regional Shoreline REC-1 cooperative monitoring) shall remain unchanged. Anticipated modifications to the monitoring program will be coordinated so as to provide a comprehensive picture of the ecological and statistical significance of monitoring results and to determine cumulative impacts of various pollutant sources. If predictable relationships among the biological, water quality and effluent monitoring variables can be demonstrated, it may be appropriate to decrease the Discharger's monitoring effort. Conversely, the monitoring program may be intensified if it appears that the objectives cannot be achieved through the Discharger's existing monitoring program. These changes will improve the overall effectiveness of monitoring in the Southern California Bight. Minor changes may be made without further public notice. 3. Special Studies, Technical Reports and Additional Monitoring Requirements a. Toxicity Reduction Requirements If the discharge exceeds an effluent limitation for toxicity specified in Table 5 and 6, the Discharger shall conduct a Toxicity Reduction Evaluation (TRE) defined in Attachment A, in accordance with an approved TRE Work Plan, and take actions to mitigate the impact of the discharge and prevent recurrence of toxicity. A TRE is not an effluent limitation for toxicity. i. TRE Work Plan Within 90 days of the Order/Permit effective date, the Discharger shall prepare and submit a copy of their Initial Investigation Toxicity Reduction Evaluation (TRE) Workplan to the Santa Ana Water Board and USEPA for review and approval by the Santa Ana Water Board Executive Officer and USEPA Water Division Director. The TRE Work Plan must be developed in accordance with USEPA guidance, EPA manual Toxicity Reduction Evaluation Guidance for Municipal Wastewater Treatment Plants (EPA/ 833/B-99/002, 1999), and be of adequate detail to allow the Discharger to immediately initiate a TRE as required in this Provision. This plan shall outline the procedures for identifying the source(s) of, and reducing or eliminating effluent toxicity and shall describe the steps the Discharger intends to follow if toxicity is measured above an acute or chronic WET permit limit. The TRE Work Plan should include, at minimum: (a) A description of the investigation and evaluation techniques that would be used to identify potential causes and sources of the exceedance, effluent variability, and/or efficiency of the treatment system in removing toxic substances. This shall include a description of an accelerated chronic toxicity testing program; (b) A description of the methods to be used for investigating and maximizing WASTE DISCHARGE REQUIREMENTS AND NPDES PERMIT 28 ORANGE COUNTY SANITATION DISTRICT ORDER NO.

Accelerated Toxicity Monitoring Specifications and TRE/TIE Initiation When a WET permit limit is exceeded during regular toxicity monitoring, and the testing meets all test acceptability criteria, the Discharger shall initiate accelerated monitoring as required below. The Discharger shall initiate a TRE to address effluent toxicity if any WET testing results exceed the WET permit limit during accelerated monitoring. (a) If an acute or chronic WET permit limit is exceeded and the source(s) of toxicity is easily identified (e.g., a temporary plant upset), then the Discharger shall make necessary corrections to the facility and shall conduct one (1) additional toxicity test using the same species and test method. This test shall begin within 14 days of notification by the laboratory of the exceedance of the WET permit limit. If the additional toxicity test does not exceed the WET permit limit, then the Discharger may return to their regular testing frequency. (b) If an acute or chronic WET permit limit is exceeded and the source of toxicity is not known, then the Discharger shall conduct four (4) additional toxicity tests using the same species and test method, approximately every two weeks, over an eight(8) week period. This testing shall begin within 14 days of notification by the laboratory of the exceedance of the WET permit limit. The following protocol shall be used for accelerated monitoring and TRE initiation: (1) If none of the additional four (4) consecutive toxicity tests exceed the WET permit limit, then the Discharger may cease accelerated monitoring and resume their regular toxicity monitoring. However, notwithstanding the accelerated monitoring results, if there is adequate evidence of a pattern of effluent toxicity, the Santa Ana Water Board Executive Officer and/or USEPA Water Division Director may require that the Discharger initiate a TRE. (2) If one of the additional toxicity tests (in paragraphs ii(a) or ii(b) above) exceeds the WET permit limit, then, within 14 days of receipt of this test result, the Discharger shall cease accelerated monitoring and initiate a TRE using as guidance, based on the type of treatment facility, USEPA manual Toxicity Reduction Evaluation Guidance for Municipal Wastewater Treatment Plants (EPA/ 833/B-99/002, 1999).

(c) The Discharger may initiate a TIE as part of a THE to identify the causes of toxicity using the same species and test method and, as guidance, USEPA test method manuals: Toxicity Identification Evaluation: Characterization of Chronically Toxic Effluents, Phase I (EPA/600/6- 91/005F, 1992); Methods for Aquatic Toxicity Identification Evaluations, Phase II Toxicity Identification Procedures for Samples Exhibiting Acute and Chronic Toxicity (EPA/600/R-92/080, 1993); Methods for Aquatic Toxicity Identification Evaluations, Phase III Toxicity Confirmation Procedures for Samples Exhibiting Acute and Chronic Toxicity (EPA/600/R-92/081, 1993); and Marine Toxicity Identification Evaluation (TIE): Phase I Guidance Document (EPA/600/R-96-054, 1996). b. Dilution Model Update No later than 4 years after the effective date of this Order/Permit, the Discharger shall submit a work plan for an updated dilution modeling that is reflective of current operations, including the increase in RO concentrate that may be discharged upon completion of the groundwater replenishment system (GWRS) final expansion project. The purpose of the study is to determine initial dilution under a reasonable worst-case scenario (e.g., strongest density stratification and zero current). The discharger shall include explanation of the conditions and data used, assessment of compliance with applicable water quality objectives, and determination of an appropriate dilution ratio for each outfall. Specifically, the work plan shall include: • Model inputs and assumptions, • Describe trapping levels and any boundary effects in the observed range of the ambient density stratification, • Assume zero current, consistent with the California Ocean Plan, • Account for a decrease in flow and an increase in pollutant concentrations, • Include WET assessment using synthetic effluent to approximate future final conditions, and • Include a sensitivity analysis for how different inputs affect the initial dilution, including effluent temperature and density. c.

Best Management Practices and Pollution Prevention a. Pollutant Minimization Program The Discharger shall develop and conduct a Pollutant Minimization Program (PMP) as described below when there is evidence (e.g., sample results reported as detected, but not quantified (DNQ) when the effluent limitation is less than the method detection limit (MDL), sample results from analytical methods more sensitive than those methods required by this Order/Permit, presence of whole effluent toxicity, health advisories for fish consumption, results of benthic or aquatic organism tissue sampling) that a pollutant is present in the effluent above an effluent limitation and either: i. The concentration of the pollutant is reported as DNQ and the effluent limitation is less than the reported minimum level (ML), using definitions described in Attachment A and reporting protocols described in MRP section XII.B.4. ii. The concentration of the pollutant is reported as not detected (ND) and the effluent limitation is less than the MDL, using definitions described in Attachment A and reporting protocols described in MRP section XII.B.4. By March 1 of each year, the Discharger shall submit its annual PMP Report to the Santa Ana Water Board and USEPA, for the previous calendar year.

Effluent Limitations Compliance with the effluent limitations contained in section IV of this Order/Permit shall be determined as specified below. 1. Sufficient sampling and analysis shall be required to determine compliance with the effluent limitation. If the analytical result of any single sample (daily discharge) monitored monthly, or less frequently, exceeds the AMEL (or 6-month median effluent limitation), then the Discharger shall increase the monitoring frequency to weekly until compliance with the effluent limitation is demonstrated. 2. Compliance with Effluent Limitations expressed as Single Constituents Dischargers are out of compliance with the effluent limitation if the concentration of the pollutant in the monitoring sample is greater than the effluent limitation and greater than or equal to the reported Minimum Level (i.e., ML or RL). 3. Compliance with Effluent Limitations expressed as Sum of Several Constituents Dischargers are out of compliance with an effluent limitation which applies to the sum of a group of chemicals (e.g., PCBs) if the sum of the individual pollutant concentrations is greater than the effluent limitation. Individual pollutants of the group will be considered to have a concentration of zero if the constituent is reported as ND or DNQ. 4. Multiple Sample Data When determining compliance with a measure of central tendency (arithmetic mean, geometric mean, median, etc.) of multiple sample analyses and the data set contains one or more reported determinations of DNQ or ND, the Discharger shall compute the median in place of the arithmetic mean in accordance with the following procedure: a. The data set shall be ranked from low to high, ranking the reported ND determinations lowest, DNQ determinations next, followed by quantified values (if any). The order of the individual ND or DNQ determinations is unimportant. b. The median value of the data set shall be determined. If the data set has an odd number of data points, then the median is the middle value. If the data set has an even number of data points, then the median is the average of the two values around the middle unless one or both of the points are ND or DNQ, in which case the median value shall be the lower of the two data points where DNQ is lower than a value and ND is lower than DNQ. 5. Average Monthly Effluent Limitation (AMEL) If the average (or when applicable, the median determined by subsection 4 above for multiple sample data reduction) of daily discharges over a calendar month exceeds (is higher than) the AMEL for a given parameter, an alleged violation will be WASTE DISCHARGE REQUIREMENTS AND NPDES PERMIT 36 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS flagged and the Discharger will be considered out of compliance for each day of that month for that parameter (e.g., resulting in 31 days of non-compliance in a 31-day month). However, an alleged violation of the AMEL will be considered one violation for the purpose of assessing State mandatory minimum penalties. If only a single sample is collected during the calendar month and the analytical result for that sample exceeds the AMEL, the Discharger may be considered out of compliance for that calendar month. For those average monthly effluent limitations that are based on the 6-month median water quality objectives in the 2019 Ocean Plan, the daily value used to calculate these average monthly values for intermittent discharges, shall be considered to equal zero for days on which no discharge occurred. The Discharger will only be considered out of compliance for days when the discharge occurs. If no sample (daily discharge) is taken over any one calendar month, no compliance determination can be made for that month with respect to effluent violation determination, but compliance determination can be made for that month with respect to reporting violation determination. A month will begin on the first day of the calendar month and end on the last day of the calendar month, in order to calculate and report a consecutive (uninterrupted) average value for the AMEL for a calendar month. 6. Average Weekly Effluent Limitation (AWEL) If the average (or when applicable, the median determined by subsection 4 above for multiple sample data reduction) of daily discharges over a calendar week exceeds (is higher than) the AWEL for a given parameter, an alleged violation will be flagged and the Discharger will be considered out of compliance for each day of that week for that parameter (e.g., resulting in seven days of non-compliance). However, an alleged violation of the AWEL will be considered one violation for the purpose of assessing State mandatory minimum penalties. The average of daily discharges over a calendar week that exceeds the AWEL for a parameter will be considered out of compliance for that week only. If only a single sample is collected during the calendar week and the analytical result for that sample exceeds the AWEL, the Discharger will be considered out of compliance for that calendar week. If no sample (daily discharge) is taken over a calendar week, no compliance determination can be made for that week with respect to effluent violation determination, but compliance determination can be made for that week with respect to reporting violation determination. A calendar week will begin on Sunday and end on Saturday. Partial calendar weeks at the end of the calendar month will be carried forward to the next month in order to calculate and report a consecutive seven-day average value for the AWEL on Saturday. 7. Maximum Daily Effluent Limitation (MDEL) If a daily discharge on a calendar day exceeds (is higher than) the MDEL for a given parameter, an alleged violation will be flagged and the Discharger will be considered out of compliance for that day for that parameter. If no sample (daily discharge) is taken over a calendar day, no compliance determination can be made for that day WASTE DISCHARGE REQUIREMENTS AND NPDES PERMIT 37 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS with respect to effluent violation determination, but compliance determination can be made for that day with respect to reporting violation determination. 8. Instantaneous Minimum Effluent Limitation If the analytical result of a single grab sample exceeds (is lower than) the instantaneous minimum effluent limitation for a given parameter, an alleged violation will be flagged and the Discharger will be considered out of compliance for that single sample for that parameter. Non-compliance for each single grab sample will be considered separately (e.g., the analytical results of two grab samples taken over a calendar day that are lower than the instantaneous minimum effluent limitation would result in two instances of non-compliance with the instantaneous minimum effluent limitation). 9. Instantaneous Maximum Effluent Limitation If the analytical result of a single grab sample exceeds (is higher than) the instantaneous maximum effluent limitation for a given parameter, an alleged violation will be flagged and the Discharger will be considered out of compliance for that single sample for that parameter. Non-compliance for each single grab sample will be considered separately (e.g., the analytical results of two grab samples taken over a calendar day that both are higher than the instantaneous maximum effluent limitation would result in two instances of non-compliance with the instantaneous maximum effluent limitation). 10.Six-month Median Effluent Limitation (i.e., 180-day Median Effluent Limitation) If the median of daily discharges over any 180-day period exceeds (is higher than) the 6-month median effluent limitation for a given parameter, an alleged violation will be flagged and the Discharger will be considered out of compliance for each day of that 180-day period (e.g., resulting in 180 days of non-compliance in any 180-day period). The next assessment of compliance will occur when the next sample is taken. If only a single sample is collected during a given 180-day period and the analytical result for that sample exceeds the six-month median, the Discharger will be considered out of compliance for the 180-day period. If no sample (daily discharge) is taken over a 180-day period, no compliance determination can be made for that period with respect to effluent violation determination, but compliance determination can be made for that period with respect to reporting violation determination. 11.Mass and Concentration Limitations Compliance with mass and concentration effluent limitations for the same parameter shall be determined separately with their respective limitations. When the concentration of a constituent in an effluent sample is determined to be ND or DNQ, the corresponding mass emission rate determined from that sample concentration shall also be reported as ND or DNQ. 12.Mass Emission Rate WASTE DISCHARGE REQUIREMENTS AND NPDES PERMIT 38 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS The daily discharge mass emission rate for any calendar day is calculated using the following equations: Daily Discharge mass emission rate (lb/day) = 8.34 " Y1QiCiN in which "N" is the number of samples taken over any calendar day. If grab samples are taken, "Ci" is the constituent concentration (mg/L) and "Qi" is the flow rate (MGD) associated with each "N" grab sample. If composite samples are taken, "Ci" is the constituent concentration (mg/L) in each composite sample and "Qi" is the average flow rate (MGD) during the period over which sample compositing occurs. The daily discharge concentration of a constituent shall be determined from the flow- weighted average of the same constituent in the combined waste stream using the following equation: N Daily discharge concentration = Q C Qt i=1 in which "N" is the number of component waste streams. "Ci" is the constituent concentration (mg/L) and "Qi" is the flow rate (MGD) associated with each "N" component waste stream. "Qt" is the total flow rate of the combined waste stream. 13.Bacterial Standards and Analysis a. The geometric mean used for determining compliance with bacterial standards is calculated with the following equation: Geometric Mean = (Cl x C2 x ... x Cn)1/n where In is the number of days samples were collected during the period and C is the concentration of bacteria (MPN/100 mL or CFU/100 mL) found on each day of sampling. b. For bacterial analyses, sample dilutions should be performed so the expected range of values is bracketed (for example, with multiple tube fermentation method or membrane filtration method, 2 to 16,000 per 100 mL for total and fecal coliform, at a minimum, and 1 to 1000 per 100 mL for Enterococcus). The detection methods used for each analysis shall be reported with the results of the analyses. c. Detection methods used for coliforms (total and fecal) and enterococcus shall be those presented in Table IA of 40 CFR § 136, unless alternate methods have been approved by USEPA pursuant to 40 CFR § 136, or improved methods have been determined by the Santa Ana Water Board and/or USEPA. 14.Sample Reporting Protocols The Discharger must report with each sample result the reported Minimum Level, selected and used in accordance with Ocean Plan Chapters III.C.5 and 6, the laboratory's current Method Detection Limit. In accordance with Ocean Plan Chapter III.C.7, the Discharger must also report the results of analytical determinations for WASTE DISCHARGE REQUIREMENTS AND NPDES PERMIT 39 ORANGE COUNTY SANITATION DISTRICT ORDER NO.

For ambient water concentrations, the arithmetic mean is calculated as follows: Arithmetic mean = µ = Y_x / n where: Ix is the sum of the measured ambient water concentrations, and n is the number of samples. Areas of Special Biological Significance (ASBS) Those areas designated by the State Water Board as ocean areas requiring protection of species or biological communities to the extent that maintenance of natural water quality is assured. All Areas of Special Biological Significance are also classified as a subset of STATE WATER QUALITY PROTECTION AREAS (SWQPA). ASBS are also referred to as State Water Quality Protection Areas —Areas of Special Biological Significance (SWQPA-ASBS). Average Monthly Effluent Limitation (AMEL) Means the highest allowable average of daily discharges over a calendar month, calculated as the sum of all "daily discharges" measured during a calendar month divided by the number of "daily discharges" measured during that month. (40 CFR § 122.2) Average Weekly Effluent Limitation (AWEL) Means the highest allowable average of daily discharges over a calendar week (Sunday through Saturday), calculated as the sum of all daily discharges measured during a calendar week divided by the number of"daily discharges" measured during that week. (40 CFR § 122.2) Best Management Practices (BMPs) Means schedules of activities, prohibitions of practices, maintenance procedures, and other management practices to prevent or reduce the pollution of "waters of the United States". BMPs also include treatment requirements, operating procedures, and practices to control plant site runoff, spillages or leaks, sludge or waste disposal, or drainage from raw material storage. (40 CFR § 122.2) Chlordane Shall mean the sum of chlordane-alpha, chlordane-gamma, chlordene-alpha, chlordene- gamma, nonachlor-alpha, nonachlor-gamma, and oxychlordane. Chlorinated Phenols The sum of 2-chlorophenol, 2,4-dichlorophenol, 4-chloro-3-methylphenol, 2,4,6-trichlorophenol, and pentachlorophenol. Coefficient of Variation (CV) CV is a measure of the data variability and is calculated as the estimated standard deviation divided by the arithmetic mean of the observed values. Composite Sample Means a time-proportioned mixture of not less than eight discrete aliquots obtained at equal time intervals (e.g., 24-hour composite means a minimum of eight samples collected every three hours).

The compositing period shall equal the specified sampling period, or 24 hours, if no period is specified. For a composite sample, if the duration of the discharge is less than 24 hours but greater than 8 hours, at least eight flow-weighted individual sample portions shall be taken during the duration of the discharge and composited. For a discharge duration of 8 hours or less, eight individual "grab samples" may be substituted and composited. Daily Discharge Daily Discharge is defined as either (1) the total mass of the constituent discharged over the calendar day (12:00 am through 11:59 pm) or any 24-hour period that reasonably represents a calendar day for purposes of sampling (as specified in the permit), for a constituent with limitations expressed in units of mass; or (2) the unweighted arithmetic mean measurement of the constituent over the day for a constituent with limitations expressed in other units of measurement (e.g., concentration). The daily discharge may be determined by the analytical results of a composite sample taken over the course of one day (a calendar day or other 24-hour period defined as a day), or by the arithmetic mean of analytical results from one or more grab samples taken over the course of one day. For composite sampling, if one day is defined as a 24-hour period other than a calendar day, the analytical result for the 24-hour period will be considered as the result for the calendar day in which the 24-hour period ends. DDT Shall mean the sum of 4,4'DDT, 2,4'DDT, 4,4'DDE, 2,4'DDE, 4,4'DDD, 2,4'DDD, and 4,4'DDMU.

Other groups may be evaluated where benthic species are not affected, or are not the only ones affected. Detected, but Not Quantified (DNQ) Sample results that are less than the reported Minimum Level (ML), but greater than or equal to the laboratory's Maximum Detection Limit (MDL). Sample results reported as DNQ are estimated concentrations. Dichlorobenzenes Shall mean the sum of 1,2- and 1,3-dichlorobenzene. Dilution Credit Dilution Credit is the amount of dilution granted to a discharge in the calculation of a water quality-based effluent limitation, based on the allowance of a specified mixing zone. It is calculated from the dilution ratio or determined through conducting a mixing zone study or modeling of the discharge and receiving water.

CA0110604 COLLECTION SYSTEM & OUTFALLS Downstream Ocean Waters Shall mean waters downstream with respect to ocean currents. Dredged Material Any material excavated or dredged from the navigable waters of the United States, including material otherwise referred to as "spoil". Eelgrass Beds Are aggregations of the aquatic plant species of the genus Zostera. Enclosed Bays Are indentations along the coast which enclose an area of oceanic water within distinct headlands or harbor works. Enclosed bays include all bays where the narrowest distance between headlands or outermost harbor works is less than 75 percent of the greatest dimension of the enclosed portion of the bay. This definition includes but is not limited to: Humboldt Bay, Bodega Harbor, Tomales Bay, Drakes Estero, San Francisco Bay, Morro Bay, Los Angeles Harbor, Upper and Lower Newport Bay, Mission Bay, and San Diego Bay. Enclosed bays do not include inland surface waters or ocean waters. Endosulfan Shall mean the sum of endosulfan-alpha and -beta and endosulfan sulfate. Estuaries and Coastal Lagoons Are waters at the mouths of streams that serve as mixing zones for fresh and ocean waters during a major portion of the year. Mouths of streams that are temporarily separated from the ocean by sandbars shall be considered as estuaries. Estuarine waters will generally be considered to extend from a bay or the open ocean to the upstream limit of tidal action but may be considered to extend seaward if significant mixing of fresh and salt water occurs in the open coastal waters. The waters described by this definition include but are not limited to the Sacramento-San Joaquin Delta as defined by section 12220 of the California Water Code, Suisun Bay, Carquinez Strait downstream to Carquinez Bridge, and appropriate areas of the Smith, Klamath, Mad, Eel, Noyo, Russian, Klamath, San Diego, and Otay Rivers. Estuaries do not include inland surface waters or ocean waters. Facility or Activity Means any NPDES "point source" or any other facility or activity (including land or appurtenances thereto) this is subject to regulation under the NPDES program. (40 CFR § 122.2) Geometric Mean (GM) Is a type of mean or average that indicates the central tendency or typical value of a set of numbers by using the product of their values (as opposed to the arithmetic mean which uses their sum). The geometric mean is defined as the nth root of the product of n numbers. The formula is expressed as: GM = (Cl x C2 x ... x Cn)'in, where C is the sample value and n is the number of samples taken. Grab Sample Is a single sample collected during a period of time, not to exceed 15 minutes, which represents the composition of the discharge only at a particular time and place. Grab samples ATTACHMENT A- DEFINITIONS A-3 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO.

Halomethanes Shall mean the sum of bromoform, bromomethane (methyl bromide) and chloromethane (methyl chloride). HCH Shall mean the sum of the alpha, beta, gamma (lindane) and delta isomers of hexachlorocyclohexane. Indicator Bacteria Includes total coliform bacteria, fecal coliform bacteria (or E. coli) and/or Enterococcus bacteria. Initial Dilution Is the process which results in the rapid and irreversible turbulent mixing of wastewater with ocean water around the point of discharge. For a submerged buoyant discharge, characteristic of most municipal and industrial wastes that are released from the submarine outfalls, the momentum of the discharge and its initial buoyancy act together to produce turbulent mixing. Initial dilution in this case is completed when the diluting wastewater ceases to rise in the water column and first begins to spread horizontally. For shallow water submerged discharges, surface discharges, and non-buoyant discharges, characteristic of cooling water wastes and some individual discharges, turbulent mixing results primarily from the momentum of discharge. Initial dilution, in these cases, is considered to be completed when the momentum induced velocity of the discharge ceases to produce significant mixing of the waste, or the diluting plume reaches a fixed distance from the discharge to be specified by the Santa Ana Water Board and/or USEPA, whichever results in the lower estimate for initial dilution. Instantaneous Maximum Effluent Limitation The highest allowable value for any single grab sample or aliquot (i.e., each grab sample or aliquot is independently compared to the instantaneous maximum effluent limitation). Instantaneous Minimum Effluent Limitation The lowest allowable value for any single grab sample or aliquot (i.e., each grab sample or aliquot is independently compared to the instantaneous minimum effluent limitation). Kelp Beds Are aggregations of marine algae of the order Laminariales, including species in the genera Macrocystis, Nereocystis, and Pelagophycus. Kelp beds include the total foliage canopy throughout the water column. Mariculture The culture of algae, plants, and animals in marine waters independent of any pollution source.

According to the California Public Resources Code (§§ 36600 et seq.) there are six classifications of marine managed areas, including State Marine Reserves, State Marine Parks and State Marine Conservation Areas, State Marine Cultural Preservation Areas, State Marine Recreational Management Areas, and State Water Qualtiy Protection Areas. Material (a) In common usage: (1) the substance or substances of which a thing is made or composed (2) substantial; (b) For purposes of the Ocean Plan relating to waste disposal, dredging and the disposal of dredged material and fill, MATERIAL means matter of any kind or description which is subject to regulation as waste, or any material dredged from the navigable waters of the United States. See also, DREDGED MATERIAL. Maximum Daily Effluent Limitation (MDEL) The highest allowable daily discharge of a pollutant, over a calendar day (or 24-hour period) (40 CFR § 122.2). For pollutants with limitations expressed in units of mass, the daily discharge is calculated as the total mass of the pollutant discharged over the day. For pollutants with limitations expressed in other units of measurement, the daily discharge is calculated as the arithmetic mean measurement of the pollutant over the day. Also, Maximum Daily Discharge Limitation (MDDL). Median The middle measurement in a set of data. The median of a set of data is found by first arranging the measurements in order of magnitude (either increasing or decreasing order). If the number of measurements (n) is odd, then the median = X(n+1)/2. If n is even, then the median = (Xn/2 + X(n/2)+1)/2 (i.e., the midpoint between the n/2 and n/2+1). Method Detection Limit (MDL) Is the minimum measured concentration of a substance that can be reported with 99 percent confidence that the measured concentration is distinguishable from method blank results, as defined in 40 CFR § 136, Appendix B. Minimum Level (ML) Is the concentration at which the entire analytical system must give a recognizable signal and acceptable calibration point. The ML is the concentration in a sample that is equivalent to the concentration of the lowest calibration standard analyzed by a specific analytical procedure, assuming that all the method-specified sample weights, volumes and processing steps have been followed. Mixing Zone Mixing Zone is a limited volume of receiving water that is allocated for mixing with a wastewater discharge where water quality criteria can be exceeded without causing adverse effects to the overall water body. Multiport Diffusers Are linear structures consisting of spaced ports or nozzles that are installed on submerged marine outfalls. Municipal Separate Storm Sewer System (MS4) Has the same meaning as set forth in 40 CFR § 122.26(b)(8). ATTACHMENT A- DEFINITIONS A-5 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS Natural Light Reduction of natural light may be determined by the Santa Ana Water Board and USEPA by measurement of light transmissivity or total irradiance, or both, according to the monitoring needs of the Santa Ana Water Board and USEPA. No Discharge Zone (NDZ) Is an area in which both treated and untreated sewage discharges from vessels are prohibited. Within NDZ boundaries, vessel operators are required to retain their sewage discharges onboard for disposal at sea (beyond 3 nautical miles from shore) or onshore at a pump-out facility. Non-Chlorinated Phenols The sum of 2,4-dimethylphenol, 2-nitrophenol, 4-nitrophenol, 2,4-dinitrophenol, 4,6-dinitro-2- methylphenol, and phenol. Non-Storm Water Discharge Is any runoff that is not the result of a precipitation event. This is often referred to as "dry weather flow". Not Detected (ND) Sample results which are less than the laboratory's MDL. Ocean Waters Are the territorial marine waters of the State as defined by California law to the extent these waters are outside of enclosed bays, estuaries, and coastal lagoons. If a discharge outside the territorial waters of the State could affect the quality of the waters of the State, the discharge may be regulated to assure no violation of the Ocean Plan will occur in ocean waters. PAHs (polynuclear aromatic hydrocarbons) The sum of acenaphthylene, anthracene, 1,2-benzanthracene (benzo[a]a nth race ne), benzo[b/j]fluoranthene, benzo[k]fluoranthene, 1,12-benzoperylene (benzo[ghi]perylene), benzo[a]pyrene, chrysene, dibenzo[ah]anthracene, fluorene, indeno[1,2,3-cd]pyrene, phenanthrene and pyrene. PCBs (polychlorinated biphenyls) as Aroclors The sum of chlorinated biphenyls whose analytical characteristics resemble those of Aroclor- 1016, Aroclor-1221, Aroclor-1232, Aroclor- 1242, Aroclor-1248, Aroclor-1254 and Aroclor- 1260. PCBs as congeners The sum of the following 41 individually quantified PCB congeners or mixtures of isomers of a single congener in a co-elution: PCB-18, 28, 37, 44, 49, 52, 66, 70, 74, 77, 81, 87, 99, 101, 105, 110, 114, 118, 119, 123, 126, 128, 138, 149, 151 , 153, 156, 157, 158, 167, 168, 169, 170, 177, 180, 183, 187, 189, 194, 201, and 206. Permitting Authority Means the State Water Board or Regional Waterboard, whichever issues the permit, and USEPA which issues the permit. Pollutant Minimization Program (PMP) ATTACHMENT A- DEFINITIONS A-6 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS PMP means waste minimization and pollution prevention actions that include, but are not limited to, product substitution, waste stream recycling, alternative waste management methods, and education of the public and businesses. The goal of the PMP shall be to reduce all potential sources of the 2019 Ocean Plan Table 3 pollutants through pollutant minimization (control) strategies, including pollution prevention measures as appropriate, to maintain the effluent concentration at or below the water quality-based effluent limitation. Pollution prevention measures may be particularly appropriate for persistent bioaccumulative priority pollutants where there is evidence that beneficial uses are being impacted. The Santa Ana Water Board and USEPA may consider cost effectiveness when establishing the requirements of a PMP. The completion and implementation of a Pollution Prevention Plan, if required pursuant to Water Code section 13263.3(d), shall be considered to fulfill the PMP requirements. Pollution Prevention Any action that causes a net reduction in the use or generation of a hazardous substance or other pollutant that is discharged into water and includes, but is not limited to, input change, operational improvement, production process change, and product reformulation (as defined in CWC section 13263.3). Pollution prevention does not include actions that merely shift a pollutant in wastewater from one environmental medium to another environmental medium, unless clear environmental benefits of such an approach are identified to the satisfaction of the State Water Resources Control Board (State Water Board), Santa Ana Water Board, or USEPA. Publicly-Owned Treatment Works (POTWs) A treatment works as defined by section 212 of the CWA, which is owned by a State or municipality (as defined by section 502(4) of the Act). This definition includes any devices and systems used in the storage, treatment, recycling and reclamation of municipal sewage or industrial wastes of a liquid nature. It also includes sewers, pipes and other conveyances only if they convey wastewater to a POTW Treatment Plant. The term also means the municipality which has jurisdiction over the Indirect Discharges to and the discharges from such treatment works. (40 CFR § 403.3(q).) Reported Minimum Level (RML) Is the ML (and its associated analytical method) chosen by the Discharger for reporting and compliance determination from the MLs included in their permit, which is also known as the Reporting Level (RL). The MLs included in this permit correspond to approved analytical methods for reporting a sample result that are selected by the Santa Ana Water Board in accordance with Ocean Plan Chapter III.C.5. The ML is based on the proper application of method-specific analytical procedures and the absence of any matrix interferences. Other factors may be applied to the ML depending on the specific sample preparation steps employed. For example, the treatment typically applied where there are matrix-effects is to dilute the sample or sample aliquot by a factor of ten. In such cases, this additional factor must be applied to the ML in the computation of the reported ML. (See Chapter III.C.6 of the 2019 Ocean Plan.). Salinity Is a measure of the dissolved salts in a volume of water. For the purposes of the Ocean Plan, salinity shall be measured using a standard method approved by the Santa Ana Water Board ATTACHMENT A- DEFINITIONS A-7 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS and USEPA (e.g., Standard Method 2520 B, EPA Method 120.1, EPA Method 160.1) and reported in parts per thousand (ppt). For historical salinity data not recorded in parts per thousand, the Santa Ana Water Boards and USEPA may accept converted data at their discretion. Seawater Is salt water that is in or from the ocean. Sensitive Habitats For the purposes of the Ocean Plan, are kelp beds, rocky substrate, surfgrass beds, eelgrass beds, oyster beds, spawning grounds for State or federally managed species, market squid nurseries, or other habitats in need of special protection as determined by the Water Boards. Shellfish Are organisms identified by the California Department of Public Health as shellfish for public health purposes (i.e., mussels, clams and oysters). Significant Difference Is defined as a statistically significant difference in the means of two distributions of sampling results at the 95 percent confidence level, unless otherwise specified by the permitting authority. Single Sample Maximum (SSM) A maximum value not to be exceeded in any single sample. Six-Month Median Effluent Limitation (i.e., 180-Day Median Effluent Limitation) The highest allowable moving median of daily values for any 180-day period in which daily values represent flow weighted average concentrations within a 24-hour period. For intermittent discharges, the daily value shall be considered to equal zero for days on which no discharge occurred. Standard Deviation (a) Standard Deviation is a measure of variability that is calculated as follows: 6 = (y[(x - µ)2]/(n — 1))0.5 where: x is the observed value; µ is the arithmetic mean of the observed values; and n is the number of samples. State Water Quality Protection Areas (SWQPAs) Non-terrestrial marine or estuarine areas designated to protect marine species or biological communities from an undesirable alteration in natural water quality. All AREAS OF SPECIAL BIOLOGICAL SIGNIFICANCE (ASBS) that were previously designated by the State Water Board in Resolutions 74-28, 74-32, and 75-61 are now also classified as a subset of State Water Quality Protection Areas and require special protections afforded by the Ocean Plan. State Water Quality Protection Areas — General Protection (SWQPA-GP) Designed by the State Water Board to protect marine species and biological communities from undesirable alteration in natural water quality within State Marine Parks and State Marine Conservation Areas.

B. Need to Halt or Reduce Activity Not a Defense It shall not be a defense for a Discharger in an enforcement action that it would have been necessary to halt or reduce the permitted activity in order to maintain compliance with the conditions of this Order/Permit. (40 CFR § 122.41(c).) C. Duty to Mitigate The Discharger shall take all reasonable steps to minimize or prevent any discharge or sludge use or disposal in violation of this Order/Permit which has a reasonable likelihood of adversely affecting human health or the environment. (40 CFR § 122.41(d).) D. Proper Operation and Maintenance The Discharger shall at all times properly operate and maintain all facilities and systems of treatment and control (and related appurtenances) which are installed or used by the Discharger to achieve compliance with the conditions of this Order/Permit.

(33 USC 1318(a)(4)(b); 40 CFR § 122.41(i)(4); CWC 13267, 13383.) G. Bypass 1. Definitions a. "Bypass" means the intentional diversion of waste streams from any portion of a treatment facility. (40 CFR § 122.41(m)(1)(i).) b. "Severe property damage" means substantial physical damage to property, damage to the treatment facilities which causes them to become inoperable, or substantial and permanent loss of natural resources that can reasonably be expected to occur in the absence of a bypass. Severe property damage does not mean economic loss caused by delays in production. (40 CFR § 122.41(m)(1)(ii).) 2. Bypass not exceeding limitations. The Discharger may allow any bypass to occur which does not cause effluent limitations to be exceeded, but only if it is also for essential maintenance to assure efficient operation. These bypasses are not subject to the provisions listed in Standard Provisions — Permit Compliance I.G.3, I.GA, and I.G.5. (40 CFR § 122.41(m)(2).) 3. Prohibition of bypass. Bypass is prohibited, and the Santa Ana Water Board/USEPA may take enforcement action against a Discharger for bypass, unless (40 CFR § 122.41(m)(4)(i)): a. Bypass was unavoidable to prevent loss of life, personal injury, or severe property damage (40 CFR § 122.41(m)(4)(i)(A)); ATTACHMENT D- STANDARD PROVISIONS D-3 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS b. There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities, retention of untreated wastes, or maintenance during normal periods of equipment downtime. This condition is not satisfied if adequate back-up equipment should have been installed in the exercise of reasonable engineering judgment to prevent a bypass that occurred during normal periods of equipment downtime or preventive maintenance (40 CFR § 122.41(m)(4)(i)(B)); and c. The Discharger submitted notices as required under Standard Provisions — Permit Compliance I.G.5. (40 CFR § 122.41(m)(4)(i)(C).) 4. The Santa Ana Water Board/USEPA may approve an anticipated bypass, after considering its adverse effects, if the Santa Ana Water Board/USEPA determines that it will meet the three conditions listed in Standard Provisions — Permit Compliance I.G.3. (40 CFR § 122.41(m)(4)(ii).) 5. Notice a. Anticipated bypass. If the Discharger knows in advance of the need for a bypass, it shall submit prior notice, if possible, at least ten days before the date of the bypass. The notice shall be sent to the Santa Ana Water Board and USEPA. As of December 21, 2025 all notices submitted in compliance with this section must be submitted electronically by the Discharger to the Santa Ana Water Board and USEPA or initial recipient, as defined in 40 CFR § 127.2(b), in compliance with this section and 40 CFR § 3 (including, in all cases, subpart D to part 3), 122.22 and part 127. Part 127 is not intended to undo existing requirements for electronic reporting. Prior to this date, and independent of part 127, the Discharger may be required to report electronically if specified by a particular Order/Permit or if required to do so by State law. (40 CFR § 122.41(m)(3)(i).) b. Unanticipated bypass. The Discharger shall submit a notice of an unanticipated bypass as required in Attachment D. Standard Provisions — Reporting V.E (24- hour notice). As of December 21, 2025 all notices submitted in compliance with this section must be submitted electronically by the Discharger to the Santa Ana Water Board and USEPA or initial recipient, as defined in 40 CFR § 127.2(b), in compliance with this section and 40 CFR § 3 (including, in all cases, subpart D to part 3), 122.22 and part 127. Part 127 is not intended to undo existing requirements for electronic reporting. Prior to this date, and independent of part 127, the Discharger may be required to report electronically if specified by a particular Order/Permit or if required to do so by State law. (40 CFR § 122.41(m)(3)(ii).) H. Upset Upset means an exceptional incident in which there is unintentional and temporary noncompliance with technology based permit effluent limitations because of factors beyond the reasonable control of the Discharger. An upset does not include noncompliance to the extent caused by operational error, improperly designed ATTACHMENT D- STANDARD PROVISIONS D-4 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS treatment facilities, inadequate treatment facilities, lack of preventive maintenance, or careless or improper operation. (40 CFR § 122.41(n)(1).) 1. Effect of an upset. An upset constitutes an affirmative defense to an action brought for noncompliance with such technology based permit effluent limitations if the requirements of Standard Provisions — Permit Compliance I.H.2 are met. No determination made during administrative review of claims that noncompliance was caused by upset, and before an action for noncompliance, is final administrative action subject to judicial review. (40 CFR § 122.41(n)(2).) 2. Conditions necessary for a demonstration of upset. A Discharger who wishes to establish the affirmative defense of upset shall demonstrate, through properly signed, contemporaneous operating logs, or other relevant evidence that (40 CFR § 122.41(n)(3)): a. An upset occurred and that the Discharger can identify the cause(s) of the upset (40 CFR § 122.41(n)(3)(i)); b. The permitted facility was at the time being properly operated (40 CFR § 122.41(n)(3)(ii)); and c. The Discharger submitted notice of the upset as required in Standard Provisions — Reporting V.E.2.b (24-hour notice) (40 CFR § 122.41(n)(3)(iii)). d. The Discharger complied with any remedial measures required under Standard Provisions — Permit Compliance I.C. (40 CFR § 122.41(n)(3)(iv).) 3. Burden of proof. In any enforcement proceeding, the Discharger seeking to establish the occurrence of an upset has the burden of proof. (40 CFR § 122.41(n)(4).) II. STANDARD PROVISIONS — PERMIT ACTION A. General This Order/Permit may be modified, revoked and reissued, or terminated for cause. The filing of a request by the Discharger for Order/Permit modification, revocation and reissuance, or termination, or a notification of planned changes or anticipated noncompliance does not stay any Order/Permit condition. (40 CFR § 122.41(f).) B. Duty to Reapply If the Discharger wishes to continue an activity regulated by this Order/Permit after the expiration date of this Order/Permit, the Discharger must apply for and obtain a new Order/Permit. (40 CFR § 122.41(b).) C. Transfers This Order/Permit is not transferable to any person except after notice to the Santa Ana Water Board/USEPA. The Santa Ana Water Board/USEPA may require modification or revocation and reissuance of the Order/Permit to change the name of the Discharger and incorporate such other requirements as may be necessary under the CWA and CWC. (40 CFR § 122.41(I)(3), 122.61.) ATTACHMENT D- STANDARD PROVISIONS D-5 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS III. STANDARD PROVISIONS — MONITORING A. Samples and measurements taken for the purpose of monitoring shall be representative of the monitored activity. (40 CFR § 122.41(j)(1).) B. Monitoring must be conducted according to test procedures approved under 40 CFR § 136 for the analyses of pollutants unless another method is required under 40 CFR § 1, subchapter N or O. (40 CFR § 122.41(j)(4).) C. Monitoring for quantitative data shall be conducted in accordance with sufficiently sensitive analytical methods approved under 40 CFR § 136 or required under 40 CFR § 1, subchapter N or O. For the purposes of this requirement, a method approved under 40 CFR § 136 or required under 40 CFR § 1, subchapter N or O is "sufficiently sensitive" when: 1. The method minimum level (ML) is at or below the level of the most stringent effluent limitation established in the Order/Permit for the measured pollutant or pollutant parameter, and either the method ML is at or below the level of the most stringent applicable water quality criterion for the measured pollutant or pollutant parameter or the method ML is above the applicable water quality criterion but the amount of the pollutant or pollutant parameter in the facility's discharge is high enough that the method detects and quantifies the level of the pollutant or pollutant parameter in the discharge; or 2. The method has the lowest ML of the analytical methods approved under 40 CFR § 136 or required under 40 CFR § 1, subchapter N or O for the measured pollutant or pollutant parameter. In the case of pollutants or pollutant parameters for which there are no approved methods under 40 CFR § 136 or otherwise required under 40 CFR § 1, subchapter N or O, monitoring must be conducted according to a test procedure specified in this Order for such pollutants or pollutant parameters. (40 C.F.R. §§ 122.21(e)(3),122.410)(4), 122.44(i)(1)(iv).) IV. STANDARD PROVISIONS — RECORDS A. Except for records of monitoring information required by this Order/Permit related to the Discharger's sewage sludge use and disposal activities, which shall be retained for a period of at least five (5) years (or longer as required by 40 CFR § 503), the Discharger shall retain records of all monitoring information, including all calibration and maintenance records and all original strip chart recordings for continuous monitoring instrumentation, copies of all reports required by this Order/Permit, and records of all data used to complete the application for this Order/Permit, for a period of at least three (3) years from the date of the sample, measurement, report or application. This period may be extended by request of the Santa Ana Water Board/USEPA at any time. (40 CFR § 122.41(j)(2).) B. Records of monitoring information shall include: 1. The date, exact place, and time of sampling or measurements (40 CFR § 122.41(j)(3)(i)); ATTACHMENT D- STANDARD PROVISIONS D-6 ORANGE COUNTY SANITATION DISTRICT ORDER NO.

CA0110604 COLLECTION SYSTEM & OUTFALLS ATTACHMENT E — MONITORING AND REPORTING PROGRAM (MRP) Section 308 of the federal Clean Water Act (CWA) and 40 CFR § 122.41(h), (j)-(I), 122.44(i) and 122.48 require that all NPDES permits specify monitoring and reporting requirements. California Water Code (CWC) sections 13267 and 13383 also authorize the Santa Ana Water Board to establish monitoring, inspection, entry, reporting, and recordkeeping requirements. This MRP establishes monitoring, reporting, and recordkeeping requirements that implement federal and California laws and/or regulations. The Discharger shall comply with this MRP of this Order/Permit. I. GENERAL MONITORING PROVISIONS A. The Santa Ana Water Board and USEPA, working with other groups, have developed a comprehensive basis for effluent and receiving water monitoring appropriate to large publicly-owned treatment works (POTWs) discharging to waters of the Southern California Bight. This effort has culminated in the publication by the Southern California Coastal Water Research Project (SCCWRP) of the Model Monitoring Program guidance document (Schiff, K.C., J.S. Brown and S.B. Weisberg. 2001. Model Monitoring Program for Large Ocean Dischargers in Southern California. SCCWRP Tech. Rep. #357. Southern California Coastal Water Research Project, Westminster, CA. 101 pp.). This guidance provides the principles, framework and recommended design for effluent and receiving water monitoring elements that have guided development of the monitoring program described below. B. This conceptual framework along with the California Ocean Plan has three components that comprise a range of spatial and temporal scales: (1) core monitoring; (2) regional monitoring; and (3) strategic process studies. 1. Core Monitoring. Core monitoring is local in nature and focuses on monitoring trends in quality and effects of the point source discharge. This includes discharge monitoring, as well as some aspects of receiving water monitoring. Core monitoring results for the effluent shall be submitted on monthly Discharge Monitoring Reports/State Monitoring Reports (DMR/SMR) and summarized in the annual receiving water monitoring report if needed. Core monitoring results for receiving water, including annotated QA/QC findings, shall be described and summarized in the annual receiving water monitoring report, due by March 15th of each year, for the previous fiscal year (July 1 through June 30). The annual receiving water monitoring report shall include the specified parameters for each station along with more detailed statistical comparisons, including analyses to elucidate spatial and temporal trends in the data, and in relation to the wastewater plume. Statistical methods shall include, but are not limited to, various multivariate techniques such as cluster analysis, ordination, and regression. The applicability and choice of statistical methods shall be explained in the report. 2. Regional Monitoring. Regional monitoring is focused on questions best answered by a region-wide approach that incorporates coordinated survey design and sampling techniques. Key components of regional monitoring include elements to address pollutant mass emission estimates, public health concerns, monitoring trends in natural resources, assessment of regional impacts from all contaminant ATTACHMENT E- MONITORING AND REPORTING PROGRAM E-3 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS sources, and beneficial use protection. The final designs of regional monitoring programs are developed by means of steering and technical committees comprised of participating agencies. For each component of regional monitoring, this Order/Permit specifies the required degree and nature of participation by Orange County Sanitation District (OC San), based upon its past participation in regional monitoring programs. The degree and nature of OC San's participation in regional monitoring programs shall be briefly described and summarized in the annual receiving water monitoring report. Each year, as part of the annual receiving monitoring report, the Discharger shall provide an informational report summarizing to date its contributing activities towards coordinated implementation of regional monitoring programs. Although participation in regional monitoring programs is required under this Order/Permit, revisions to Attachment E, at the direction of the Santa Ana Water Board and USEPA, may be necessary to accomplish the goals of regional monitoring. 3. Strategic Process Studies. Strategic process studies are focused on refined questions regarding specific effects or development of monitoring techniques and are anticipated to be of short duration and/or small scale, although multi-year studies may be needed. Questions regarding discharge or receiving water quality, discharge impacts, ocean processes in the area of the discharge, or development of techniques for monitoring the same, arising out of the results of core, regional monitoring, or other relevant studies shall be pursued through these studies. These studies are by nature ad hoc and, typically, cannot be anticipated in advance of the five-year permit cycle. Monitoring efforts, status of in-progress studies, and summary results for completed strategic process studies shall be briefly described and summarized in the annual receiving water monitoring report. In the spring, beginning in 2022 and continuing every-other year during the term of this Order/Permit, the Discharger, Santa Ana Water Board, and USEPA shall consult to determine the need for strategic process studies. By October 1st, the Discharger shall submit proposals to the Santa Ana Water Board and USEPA for the following fiscal year's (July 1 through June 30) monitoring effort, or a letter explaining why no special studies are proposed. Final scopes of work, including reporting schedules, shall be presented by the Discharger at a spring meeting with Santa Ana Water Board and USEPA to obtain Santa Ana Water Board and USEPA approval. Upon approval, the Discharger shall implement its strategic process studies. C. Every five years SCCWRP coordinates receiving water regional monitoring within the Southern California Bight and compiles monitoring data collected by the dischargers and other participating entities. The sixth regional monitoring program (Bight '18) occurred primarily during the summer of 2018. The next (seventh) regional monitoring program (Bight '23) is expected to take place during 2023. While participation in regional monitoring programs is required under this Order/Permit, revisions to the Discharger's monitoring program at the direction of the Santa Ana Water Board and ATTACHMENT E- MONITORING AND REPORTING PROGRAM E-4 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS USEPA may be necessary to accomplish the goals of regional monitoring or to allow the performance of special studies to investigate regional or site-specific water issues of concern. These revisions may include a reduction or increase in the number of parameters to be monitored, the frequency of monitoring, or the number and size of samples to be collected, which are applicable to receiving water monitoring program only. Such changes shall be authorized by the Santa Ana Water Board Executive Officer and USEPA Director upon written notification to the Discharger. Permittee participation in regional monitoring programs is required as a condition of this Order/Permit. The Discharger shall complete collection and analysis of samples in accordance with the schedule established by the Steering Committee directing the Bight-wide regional monitoring surveys. The level of participation shall be similar to that provided by the Discharger in previous regional surveys conducted in 1994, 1998, 2003, 2008, 2013, and 2018. D. All plant samples shall be representative of the waste discharge under conditions of peak load. Results of quarterly, semiannual, and annual analyses shall be reported by the due date specified in Table E-16 of the MRP. Should there be instances when monitoring could not be performed during these specified months, the Discharger must notify the Santa Ana Water Board and USEPA, state the reason why monitoring could not be conducted, and obtain approval from the Santa Ana Water Board and USEPA for an alternate schedule. E. Pollutants shall be analyzed using the analytical methods described in 40 CFR § 136; or where no methods are specified for a given pollutant, by methods approved by the Santa Ana Water Board, the State Water Board, and/or USEPA. If more than one analytical test method is listed for a given parameter, the Discharger must select from the listed methods and corresponding Minimum Level. USEPA published regulations for the Sufficiently Sensitive Methods Rule (SSM Rule) which became effective September 18, 2015. For the purposes of monitoring and reporting under the NPDES program, when more than one test procedure is approved under 40 CFR § 136 for the analysis of a pollutant or pollutant parameter, the test procedure must be sufficiently sensitive as defined at 40 CFR § 122.21(e)(3) and 122.44(i)(1)(iv). A USEPA-approved analytical method is sufficiently sensitive where: 1. The ML is at or below both the level of the applicable water quality criterion/objective and the permit limitation or performance goal for the measured pollutant or pollutant parameter; or 2. In permit applications, the ML is above the applicable water quality criterion/objective, but the amount of the pollutant or pollutant parameter in a facility's discharge is high enough that the method detects and quantifies the level of the pollutant or pollutant parameter in the discharge; or 3. The method has the lowest ML of the USEPA-approved analytical methods where none of the USEPA-approved analytical methods for a pollutant can achieve the MLs necessary to assess the need for effluent limitations or to monitor compliance with a permit limitation.

CA0110604 COLLECTION SYSTEM & OUTFALLS The MLs in Ocean Plan Appendix II remain applicable. However, there may be situations when analytical methods are published with MLs that are more sensitive than the MLs for analytical methods listed in the Ocean Plan. For instance, USEPA Method 1631 E for mercury is not currently listed in Ocean Plan Table II, but it is published with an ML of 0.5 ng/L that makes it a sufficiently sensitive analytical method. F. In conformance with federal regulations 40 CFR § 122.45(c), analyses to determine compliance with the effluent limitations for metals shall be conducted using the total recoverable method. For chromium (III) and (VI), the Discharger may, at its option, meet both the chromium (III) and the chromium (VI) limitations by analyzing for total recoverable chromium. G. Water/wastewater samples must be analyzed within allowable holding time limits as specified in 40 CFR § 136.3. All quality assurance/quality control (QA/QC) analyses must be run in the same preparation and analytical batches in which samples are actually analyzed. The Discharger shall retain the QA/QC documentation in its files and make available for inspection and/or submit this documentation when requested by the Santa Ana Water Board and/or USEPA. Proper chain of custody procedures must be followed, and a copy of this documentation shall be submitted with the monthly report. H. If the Discharger samples and performs analyses (other than for process/operational control, startup, research, or equipment testing) on any influent, effluent, or receiving water constituent more frequently than required by this Order/Permit using approved analytical methods, the results of those analyses shall be included in the monitoring report. These results shall be reflected in the calculation of the average (or median) used in demonstrating compliance with limitations set forth in this Order/Permit. I. All monitoring instruments and devices used by the Discharger to fulfill the prescribed monitoring program shall be properly maintained and calibrated as necessary to ensure their continued accuracy. In the event that continuous monitoring equipment is out of service for greater than a 24-hour period, the Discharger shall obtain a representative grab sample each day the equipment is out of service. The Discharger shall correct the cause(s) of failure of the continuous monitoring equipment as soon as practicable. In its monitoring report, the Discharger shall specify the period(s) during which the equipment was out of service and, if the problem has not been corrected, shall identify the steps which the Discharger is taking or proposes to take to bring the equipment back into service and the schedule for these actions. J. For every item of monitoring data where the requirements are not met, the monitoring report shall include a statement discussing the reasons for noncompliance, the actions undertaken or proposed that will bring the discharge into full compliance with requirements at the earliest time and an estimate of the date when the Discharger will be in compliance. The Discharger shall notify the Santa Ana Water Board and USEPA by letter when compliance with the time schedule has been achieved. K. Laboratory Certification. Laboratories analyzing monitoring samples shall be certified by the State Water Board, Environmental Laboratory Accreditation Program (ELAP), in accordance with CWC section 13176, and must include QA/QC data in their reports.

V. WHOLE EFFLUENT TOXICITY TESTING REQUIREMENTS A. Acute Whole Effluent Toxicity 1. Monitoring Frequency The Discharger shall conduct acute toxicity tests on 24-hour composite effluent samples (Table E-4). Once each calendar year, at a different time of year from the previous years, the Discharger shall split a 24-hour composite effluent sample and concurrently conduct toxicity tests using a fish and an invertebrate species. The Discharger shall then continue to conduct routine quarterly toxicity testing using the single, most sensitive species.

CA0110604 COLLECTION SYSTEM & OUTFALLS Acute toxicity test samples shall be collected at the designated NPDES sampling station for the effluent. In order to better relate toxicity to other effluent characteristics, it is recommended that at least twice per year the Discharger process a split toxicity sample for analysis of all other monitored parameters specified by the effluent monitoring program. 2. Marine and Estuarine Species and Test Methods Species and short-term test methods for estimating the acute toxicity of NPDES effluents are generally found in the fifth edition of Methods for Measuring the Acute Toxicity of Effluents and Receiving Waters to Freshwater and Marine Organisms (EPA/821/R-02/012, 2002; Table IA, 40 CFR § 136). For this Order/Permit, the Discharger shall conduct 96-hour static renewal toxicity tests with topsmelt, Atherinops affinis, representing a vertebrate species (Test Method 2006.0), and the mysid, Americamysis bahia, representing an invertebrate species (Test Method 2007.0). If laboratory-held cultures of the topsmelt, Atherinops affinis, are not available for testing, then the Discharger shall conduct a 96-hour static renewal toxicity test with the inland silverside, Menidia beryllina (Test Method 2006.0). 3. Quality Assurance a. Quality assurance measures, instructions, and other recommendations and requirements are found in the test methods manuals previously referenced. Additional requirements are specified, below. b. For Discharge Point 001, an acute dilution allowance is authorized such that the critical acute instream waste concentration (IWC) is set at a percent effluent value lower than 100% effluent. The acute IWC for Discharge Point 001 is 5.56% effluent. c. Effluent dilution water and control water should be prepared and used as specified in the test methods manual for the test species. If the dilution water is different from test organism culture water, then a second control using culture water shall also be used. If the use of artificial sea salts is considered provisional in the test method, then artificial sea salts shall not be used to increase the salinity of the effluent sample prior to toxicity testing without written approval by the permitting authority. d. If organisms are not cultured in-house, then concurrent testing with a reference toxicant shall be conducted. If organisms are cultured in-house, then monthly reference toxicant testing is sufficient. Reference toxicant tests and effluent toxicity tests shall be conducted using the same test conditions (e.g., same test duration, etc.). e. If the effluent toxicity test during the reporting period for the month does not meet the Test Acceptability Criteria JAC) in the WET method (EPA/600/R- 95/136, 1995), then the permittee shall resample and retest within 14 days.

If the discharged effluent is disinfected using chlorine, then total chlorine residual shall not be removed from the effluent sample prior to toxicity testing. B. Chronic Whole Effluent Toxicity 1. Monitoring Frequency The Discharger shall conduct chronic toxicity tests on 24-hour composite effluent samples (Table E-4). Once each calendar year, at a different time of year from the previous years, the Discharger shall split a 24-hour composite effluent sample and concurrently conduct three toxicity tests using a fish, an invertebrate, and an algal species. The Discharger shall then continue to conduct routine monthly toxicity testing using the single, most sensitive species. Chronic toxicity test samples shall be collected at the designated NPDES sampling station for the effluent. In order to better relate toxicity to other effluent characteristics, it is recommended that at least twice per year the Discharger process a split toxicity sample for analysis of all other monitored parameters specified by the effluent monitoring program. 2. Marine and Estuarine Species and Test Methods Species and short-term test methods for estimating the chronic toxicity of NPDES effluents are found in the first edition of Short-term Methods for Estimating the Chronic Toxicity of Effluents and Receiving Waters to West Coast Marine and Estuarine Organisms (EPA/600/R-95/136, 1995) and applicable water quality standards; also see 40 CFR § 122.410)(4) and 122.44(d)(1)(iv), and 40 CFR § 122.21(j)(5)(viii) for POTWs. The Discharger shall conduct a static renewal toxicity test with the topsmelt, Atherinops affinis (Larval Survival and Growth Test Method 1006.0); a static non- renewal toxicity test with the giant kelp, Macrocystis pyrifera (Germination and Growth Test Method 1009.0); and a toxicity test with one of the following invertebrate species: Static non-renewal toxicity test with the red abalone, Haliotis rufescens (Larval Shell Development Test Method); Static non-renewal toxicity test with the purple sea urchin, Strongylocentrotus purpuratus, or the sand dollar, Dendraster excentricus (Fertilization Test Method 1008.0). If laboratory-held cultures of the topsmelt, Atherinops affinis, are not available for testing, then the Discharger shall conduct a static renewal toxicity test with the inland silverside, Menidia beryllina (Larval Survival and Growth Test Method 1006.0) in the third edition of Short-term Methods for Estimating the Chronic Toxicity of Effluents and Receiving Waters to Marine and Estuarine Organisms (EPA/821/R-02/014, 2002).

Quality assurance measures, instructions, and other recommendations and requirements are found in the chronic test methods manuals previously referenced. Additional requirements are specified, below. b. For Discharge Point 001 , a chronic dilution allowance is authorized such that the critical chronic instream waste concentration (IWC) is set at a percent effluent value lower than 100% effluent. The chronic IWC for Discharge Point 001 is 0.556% effluent. For Discharge Point 002, a chronic dilution allowance is authorized such that the critical chronic instream waste concentration (IWC) is set at a percent effluent value lower than 100% effluent. The chronic IWC for Discharge Point 002 is 2.78% effluent. c. Effluent dilution water and control water should be prepared and used as specified in the test methods manual Short-term Methods for Estimating the Chronic Toxicity of Effluents and Receiving Waters to West Coast Marine and Estuarine Organisms (EPA/600/R-95/136, 1995) and/or Short- term Methods for Estimating the Chronic Toxicity of Effluents and Receiving Waters to Marine and Estuarine Organisms (EPA/821/R- 02/014, 2002). If the dilution water is different from test organism culture water, then a second control using culture water shall also be used. If the use of artificial sea salts is considered provisional in the test method, then artificial sea salts shall not be used to increase the salinity of the effluent sample prior to toxicity testing without written approval by the permitting authority. d. If organisms are not cultured in-house, then concurrent testing with a reference toxicant shall be conducted. If organisms are cultured in-house, then monthly reference toxicant testing is sufficient. Reference toxicant tests and effluent toxicity tests shall be conducted using the same test conditions (e.g., same test duration, etc.). e. If the effluent toxicity test during the reporting period for the month does not meet the Test Acceptability Criteria (TAC) in the WET method (EPA/600/R- 95/136, 1995), then the permittee shall resample and retest within 14 days. The results of this retest shall only replace that effluent toxicity test that did not meet TAC during the reporting period for the month. f. If the discharged effluent is disinfected using chlorine, then total chlorine residual shall not be removed from the effluent sample prior to toxicity testing. g. pH drift during the toxicity test may contribute to artifactual toxicity when pH- dependent toxicants (e.g., ammonia, metals) are present in an effluent. To determine whether or not pH drift during the toxicity test is contributing to artifactual toxicity, the Discharger shall conduct three sets of parallel toxicity tests, in which the pH of one treatment is controlled at the pH of the effluent and the pH of the other treatment is not controlled, as described in Section 13.3.6 of the test methods manual, Short-term Methods for Estimating the ATTACHMENT E- MONITORING AND REPORTING PROGRAM E-43 ORANGE COUNTY SANITATION DISTRICT ORDER NO.

CA0110604 COLLECTION SYSTEM & OUTFALLS Chronic Toxicity of Effluents and Receiving Waters to Marine and Estuarine Organisms (EPA/821/R-02/014, 2002). Toxicity is confirmed to be artifactual and due to pH drift when no toxicity above the chronic WET permit limit is observed in the treatments controlled at the pH of the effluent. If toxicity is confirmed to be artifactual and due to pH drift, then, following written approval by the permitting authority, the Discharger may use the procedures outlined in Section 13.3.6 of the test methods manual to control sample pH during the toxicity test. C. Analysis and Reporting of Acute and Chronic Toxicity Monitoring Results 1. For Discharge Point 001 , a full toxicity laboratory report for all acute and chronic toxicity testing shall be submitted as an attachment to the Self-Monitoring Report (SMR) for the month in which the toxicity tests are initiated. The laboratory report shall contain: all toxicity test results (raw data and statistical analyses) for each effluent and related reference toxicant tested; chain-of custody; the dates of sample collection and initiation of each toxicity test; control performance; all results for other effluent parameters monitored concurrently with the effluent toxicity tests via split samples; and schedule and progress reports on THE/TIE studies. 2. For Discharge Point 002, a full toxicity laboratory report for all chronic toxicity testing shall be submitted as an attachment to the SMR for the month in which the toxicity tests are initiated. The laboratory report shall contain: all toxicity test results (raw data and statistical analyses) for each effluent and related reference toxicant tested; chain-of custody; the dates of sample collection and initiation of each toxicity test; control performance; all results for other effluent parameters monitored concurrently with the effluent toxicity tests via split samples; and schedule and progress reports on THE/TIE studies. 3. The Discharger shall notify the Santa Ana Water Board and USEPA in writing within 14 days of exceedance of an acute or chronic WET permit limit. This notification shall describe actions the Discharger has taken or will take to investigate, identify, and correct the causes of toxicity; the status of actions required by this Order/Permit; and schedule for actions not yet completed; or reason(s) that no action has been taken.

RECEIVING WATER REGIONAL MONITORING REQUIREMENTS Discharger participation in regional monitoring programs is a required condition of this Order/Permit. The Discharger shall participate in regional monitoring activities coordinated by the Southern California Coastal Water Research Project (SCCWRP), County of Orange Health Care Agency (HCA), the Southern California Coastal Ocean Observation System (SCCOOS), and other appropriate agencies once approved by the Santa Ana Water Board and USEPA. The regional monitoring programs which must be conducted under this Order/Permit include: A. Southern California Bight Regional Monitoring Program The Discharger shall continue to participate in Southern California Bight Regional Monitoring Program studies, including water quality, benthic infauna, sediment chemistry, fish communities, fish predator risk, and ocean acidification, which are coordinated through the Southern California Coastal Water Research Project (SCCWRP) (e.g., the 1994 Southern California Bight Pilot Project, Bight'98, Bight'03, Bight'08, Bight'13, and Bight'18). Participation in the Southern California Bight Regional Monitoring Program shall include aspects of the program relevant to understanding regional trends and answering regional questions related to public health (i.e., bacterial contamination), water quality, sediment geochemistry, biological communities, and seafood safety (e.g., fish tissue contamination) in the receiving waters environment. For sediment chemistry and benthic infauna communities, this level of effort shall be similar to the 35 one-off (i.e., 1/5-year) summer samples. For trawls, participation shall be equivalent to the 8 annual summer samples. In both cases (i.e., the benthic and trawl programs), 22 quarterly/annual benthic stations and 6 semi-annual trawl stations identified in the monitoring program should continue to be sampled, even during regional monitoring program events, to assess compliance and trends near the discharge. The Discharger shall complete collection, analysis, and reporting of samples in accordance with the schedules established by the next Bight regional program ATTACHMENT E- MONITORING AND REPORTING PROGRAM E-57 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS development committee(s). Previous participation included method development, research, and monitoring activities involving microbiology, water quality data, marine sediments, fish/macrobenthic assemblages, fish tissue contamination, and harmful algal blooms related to point and nonpoint discharges to the marine environment. Levels of participation and areas of study are dependent upon the final study plans established by Bight regional program development committees, but will be equivalent to that provided by the Discharger in previous regional surveys conducted in 1994, 1998, 2003, 2008, 2013, and 2018. For Bight'18, this involved: 1. Participation in regional microbiological studies testing rapid methods and developing rapid methods for detection of fecal indicator bacteria in beach sands at 2 beach stations. 2. Collection and analysis of water quality samples for analyzing the relationship between nutrients discharged through POTW outfalls, upwelling, and harmful algal blooms. Note that this study was deferred to Bight'23 due to logistical sample deployment issues. 3. Collection and analysis of water quality samples for ocean acidification and hypoxia (OAH), including bongo net towing to collect pteropods, at 4 bongo net tow stations. 4. Collection and analysis of sediment grab samples for geochemistry and benthic infauna at 44 benthic stations . 5. Collection and analyses of fish and macroinvertebrate community structure at 21 trawl stations. 6. Collection and analysis of fish tissue from approximately two zones or the equivalent of 40 tissue samples for chemical contaminants (organics and metals), and analysis of selected biomarkers at a subset of these stations. B. Southern California Bight Regional Water Quality Program The Southern California Bight Regional Water Quality Program (SCBRWQP; previously known as the Central Bight Water Quality Cooperative Program or the Central Bight Regional Water Quality Monitoring Program) is a coordinated quarterly receiving water quality monitoring program conducted by OC San, the County Sanitation Districts of Los Angeles, the City of Los Angeles, the City of San Diego, and the City of Oxnard. 1.

E. Ocean Acidification and Hypoxia (OAH) Mooring The Discharger shall monitor ocean acidification and hypoxia at a single location. An automated data quality control system shall be established for telemetered data (i.e., real-time, online ocean acidification data) based on the Integrated Ocean Observation System (IOOS) protocols. X. STRATEGIC PROCESS STUDIES The Discharger shall conduct Strategic Process Studies (SPS) to document the effectiveness of its source control and wastewater treatment operations in protecting the coastal ocean. SPS are designed to address unanswered questions raised by the Core monitoring program results and/or focus on issues of interest to the Discharger, the Santa Ana Water Board, and/or USEPA. SPS shall be proposed and be approved by the Santa Ana Water Board and USEPA to ensure appropriate focus and level of effort. Five studies below must be conducted under this Order/Permit using previously approved work plans as these studies have been approved during the term of the 2012 Order/Permit and are not yet completed: A. ROMS-BEC Ocean Outfall Modeling: The Discharger works with SCCWRP and their collaborators to model and assess the spatial and temporal extent of its discharged effluent before and after the implementation of the GWRS Final Expansion. B. Microplastics Characterization: This SPS characterizes the quantity and types of microplastics throughout the Discharger's treatment system. This study will also develop methods and analyses to help inform the transport, fate and impacts of microplastics through the Discharger's wastewater treatment process to the receiving environment. C. In-vitro Cell Bioassay Monitoring Assessment: This study will provide a preliminary assessment of contaminants of emerging concern (CEC) in the receiving water using in- vitro cell bioassay techniques. Cell bioassays can be used as a screening tool to evaluate potential impacts resulting from changes in the effluent and receiving environment water quality associated with the GWRS Final Expansion. ATTACHMENT E- MONITORING AND REPORTING PROGRAM E-61 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS D. Sediment Linear Alkylbenzenes: Linear Alkylbenzenes (LABs) were previously used to investigate whether other contaminants present in the sediment were associated with the effluent discharge. This SPS will provide updated data within the Discharger's monitoring area for evaluating future changes due to GWRS Final Expansion. E. Meiofauna Baseline: The Discharger will investigate the impacts of increased RO concentrate flows from the GWRS Final Expansion on marine biota in the receiving water using meiofauna (animals ranging from 63 to 500 dam in size) which are known to be more sensitive to anthropogenic impacts than macrofauna. This SPS will characterize the meiofauna communities in the receiving environment and evaluate the suitability of using meiofauna for a before-after control-impact study of the GWRS Final Expansion. XI. OTHER MONITORING REQUIREMENTS A. Contaminants of Emerging Concern (CEC) Monitoring Study The Discharger shall continue to investigate CEC in the discharge and/or receiving waters, following its approved CEC study workplan. Within six (6) months of the effective date of this Order/Permit, the Discharger shall submit for Executive Officer/Director approval an updated CEC study workplan and submit the special study final report with the application for permit reissuance. The workplan shall include, but is not limited to: 1. Updates of CEC identification for discharge monitoring (e.g., CEC concentrations and mass loadings, sample type, minimum sampling frequency, and analytical test method considering sensitivity, accuracy, availability, and cost). The parameters in Table E-15 may be re-evaluated and modified by the Executive officer/Director. The workplan may also propose surrogate or indicator CEC that may better characterized discharged CEC.

Reporting Protocols. The Discharger shall report with each sample result the applicable reported Minimum Level (reported ML, also known as the Reporting Level, or RL) and the current Method Detection Limit (MDL), as determined by the procedure in 40 CFR § 136. The Discharger shall report the results of analytical determinations for the presence of chemical constituents in a sample using the following reporting protocols: ATTACHMENT E- MONITORING AND REPORTING PROGRAM E-69 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS a. Sample results greater than or equal to the reported ML shall be reported as measured by the laboratory (i.e., the measured chemical concentration in the sample). b. Sample results less than the reported ML, but greater than or equal to the laboratory's MDL, shall be reported as "Detected, but Not Quantified," or DNQ. The estimated chemical concentration of the sample shall also be reported. For the purposes of data collection, the laboratory shall write the estimated chemical concentration next to DNQ. The laboratory may, if such information is available, include numerical estimates of the data quality for the reported result. Numerical estimates of data quality may be percent accuracy (± a percentage of the reported value), numerical ranges (low to high), or any other means considered appropriate by the laboratory. c. Sample results less than the laboratory's MDL shall be reported as "Not Detected," or ND. d. Dischargers are to instruct laboratories to establish calibration standards so that the ML value (or its equivalent if there is differential treatment of samples relative to calibration standards) is the lowest calibration standard. At no time is the Discharger to use analytical data derived from extrapolation beyond the lowest point of the calibration curve. 5. Compliance Determination. Compliance with effluent limitations for reportable pollutants shall be determined using sample reporting protocols defined above and Attachment A of this Order/Permit. For purposes of reporting and administrative enforcement by the Santa Ana Water Board, State Water Board, and USEPA, the Discharger shall be deemed out of compliance with effluent limitations if the concentration of the reportable pollutant in the monitoring sample is greater than the corresponding effluent limitation and greater than or equal to the reported Minimum Level (ML). 6. Multiple Sample Data. When determining compliance with a measure of central tendency (arithmetic mean, geometric mean, median, etc.) of multiple sample analyses and the data set contains one or more reported determinations of DNQ or ND, the Discharger shall compute the median in place of the arithmetic mean in accordance with the following procedure: a. The data set shall be ranked from low to high, ranking the reported ND determinations lowest, DNQ determinations next, followed by quantified values (if any). b. The median value of the data set shall be determined. If the data set has an odd number of data points, then the median is the middle value. If the data set has an even number of data points, then the median is the average of the two values around the middle unless one or both of the points are ND or DNQ, in which case the median value shall be the lower of the two data points where DNQ is lower than a value and ND is lower than DNQ. 7. The Discharger shall submit SMRs in accordance with the following requirements: ATTACHMENT E- MONITORING AND REPORTING PROGRAM E-70 ORANGE COUNTY SANITATION DISTRICT ORDER NO.

For the purposes of this Order/Permit, references to the "discharger" or "permittee" in applicable federal and state laws, regulations, plans, or policy are held to be equivalent to references to the Discharger herein. B. The Facility discharges wastewater to the Pacific Ocean, a water of the United States. The Discharger was previously regulated by Order No. R8-2012-0035 and National Pollutant Discharge Elimination System (NPDES) Permit No. CA0110604 adopted on June 15, 2012 and expired on July 19, 2017. The Discharger filed a report of waste discharge and submitted an application for reissuance of its waste discharge requirements (WDRs) and NPDES permit on January 3, 2017, and the previous order was administratively extended by operation of law. Attachment B provides a map of the area around the Facility. Attachment C provides a flow schematic of the Facility. C. Regulations at 40 CFR § 122.46 limit the duration of NPDES permits to a fixed term not to exceed five years. Accordingly, Table 3 of this Order/Permit limits the duration of the discharge authorization. However, pursuant to California Code of Regulations, title 23, section 2235.4, the terms and conditions of an expired permit are automatically continued pending reissuance of the permit if the Discharger complies with all federal NPDES requirements for continuation of expired permits. (See also 40 CFR § 122.6(d)). II. FACILITY DESCRIPTION A. Description of Wastewater and Biosolids Treatment and Controls The Discharger's POTW serves approximately 480 square miles of central and northern Orange County, California. Currently, the POTW consists of approximately ATTACHMENT F- FACT SHEET F-5 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS 388 miles of trunk sewer systems and force mains, 15 offsite pump stations, two wastewater treatment plants, and three outfalls. In addition to the domestic, commercial, and industrial wastewater received from this service area, through interagency agreements, influent flows are contributed by the Santa Ana Watershed Project Authority (SAWPA) including Stringfellow Superfund Site (EPA ID #CAT080012826), Irvine Ranch Water District, and the Sanitation District of Los Angeles County. During dry weather conditions, the Discharger also accepts small volumes (average daily amount up to 10 MGD) of dry weather urban runoff from within the service area. During 2018-2019, the Discharger's wastewater treatment plants received and processed influent volumes averaging 191 MGD. Raw wastewater entering either Reclamation Plant No. 1 or Treatment Plant No. 2 passes through metering and diversion structures and continues to headworks facilities for preliminary treatment. Note that influent flow from SAWPA is tributary to Reclamation Plant No. 1 via the Santa Ana River Interceptor (SARI). Because the California Department of Health does not permit SARI flow for the Groundwater Replenishment System (GWRS) reclamation, all SARI flow is diverted to Treatment Plant No. 2 through the Interplant Interceptor for treatment and ocean discharge. Preliminary treatment includes grit and screenings removal. Caustic soda shock, ferrous chloride, calcium nitrate, magnesium hydroxide and polymer can be added to reduce corrosion and odor and provide enhanced primary treatment. The wastewater then receives primary treatment in primary sedimentation facilities. The primary effluent is routed to either trickling filters or activated sludge facilities for secondary treatment. Secondary treated trickling filter and activated sludge effluents from Reclamation Plant No. 1 are delivered to the Orange County Water District (OCWD) for further tertiary treatment and reclamation. The OC San discharges secondary treated effluent from Treatment Plant No. 2 through Discharge Point 001 (primary 120" ocean outfall) to the Pacific Ocean, a water of the United States, except under emergency circumstances. In 2023, when the Final Expansion of the GWRS is complete, Treatment Plant No. 2 effluents will also be reclaimed at the GWRS. SARI flow will be separated from other domestic wastewater at Plant No. 2, where it will be secondary treated before being discharged to the ocean. The use of continuous disinfection prior to discharge through Discharge Point No. 001 (120" outfall) has been ceased since May 2015. Effluent disinfection with chlorine bleach followed by de- chlorination with sodium bisulfite occurs at the other two discharge points 002 and 003. Dewatered biosolids are shipped offsite to land application, composting, thermal conversion, or landfill facilities. Attachment B provides a map of the area around the treatment facilities. Attachment C provides flow schematics of the full secondary treatment facilities. OCWD receives two streams of OC San secondary treated wastewater, one for the Green Acres Project (GAP, out of service in winter) and the second one for the GWRS. Both GAP and GWRS are major regional wastewater reclamation projects owned and operated by OCWD and located adjacent to Reclamation Plant No. 1. Advanced treatment for the GWRS includes microfiltration, reverse osmosis, and advance oxidation (ultraviolet/peroxide). The Discharger provides approximately 100 % of secondary treated effluent from Plant No.1 to GWRS for advanced treatment and ATTACHMENT F- FACT SHEET F-6 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS reuse. In Fiscal Year 2018-19, the average effluent flow to OCWD was 117 MGD. The GWRS Final Expansion has been under construction since November 2019, which supports the Discharger's strategic goal of maximizing water recycling up to 175 MGD at both plants, and OCWD's goal to produce up to 130 MGD of purified recycled water by 2023. GAP can divert up to 7.5 MGD of the Discharger's secondary treated wastewater for tertiary treatment, disinfection, and reuse for landscaped irrigation and industrial uses. In Fiscal Year 2018-19 summer months, average flow to GAP was 4 MGD. The GAP and part of the GWRS generates waste streams (e.g., microfiltration backwash, sump waste, and lime waste) are recycled back into the OC San's primary treatment facility, except for RO reject (or concentrate) which are returned to OC San, blended with other secondary treated waste streams and discharged via ocean outfalls. In 2019, average daily total influent flow to both plants was 192 MGD, but because of water recycling efforts, the average daily ocean discharge was 100 MGD. Based on 2017 OCSD Facilities Master Plan, the average daily influent flow projected for 2025 is 188-206 MGD during the dry weather season and 478-523 MGD during the peak wet weather season. Note that lower and upper bound flows are based on the current trend and a conservative approach, respectively. The projected 2025 average daily ocean discharges are 55-73 MGD for dry weather and 344-389 MGD for peak wet weather, of which RO concentrate flow is 23 MGD. B. Discharge Points and Receiving Waters Secondary treated effluents from Plant No. 1 and 2 are discharged to the Pacific Ocean through the Discharger's ocean outfall system. There are two booster pump stations (i.e., the Ocean Outfall Booster Station (OOBS) and the Effluent Pump Station Annex (EPSA)) that pump secondary effluent to two ocean outfalls: Discharge Point 001 via the 120" pipelines and Discharge Point 002 via the 78" pipelines. In addition to these two ocean outfalls, there are two overflow weirs at Plant No. 2 that discharge into the Santa Ana River. 1. Discharge Point 001 (120" outfall). Discharge Point 001 (120" outfall) is the primary discharge point (activated ocean outfall, with a rated capacity of 480 MGD) to the Pacific Ocean terminating in a diffuser with 503 ports, at a depth of about 197 feet (60 meters) below mean sea level. Discharge Point 001 (120" outfall) is approximately 4.5 miles (3.9 nautical miles) offshore in federal waters as the territorial waters of the State end 3 nautical miles from shore. The Ocean Plan (Appendix 1, Ocean Waters) states, "If a discharge outside the territorial waters of the State could affect the quality of the waters of the State, the discharge may be regulated to assure no violation of the Ocean Plan will occur in ocean waters." This Order/Permit contains discharge prohibitions, effluent limitations, receiving water limitations, and other provisions to ensure that discharges from Discharge Point 001 do not affect State waters. The Ocean Plan minimum probable initial dilution (Dm = 180) for this outfall is 181:1. 2. Discharge Point 002 (78" outfall). Discharge Point 002 (78" outfall) is an emergency discharge point (deactivated ocean outfall, with a rated capacity of 230 ATTACHMENT F- FACT SHEET F-7 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS MGD) to the Pacific Ocean terminating in a 130 ports diffuser, approximately 1.5 mile offshore from the mouth of the Santa Ana River, at a depth of about 65 feet (20 meters) below mean sea level. This outfall is used only during an emergency or planned essential maintenance or capital improvement projects to assure efficient operation of the 120" outfall under 40 CFR § 122.41(m)(2) since the 120" outfall was put into service in 1971 . The Ocean Plan minimum probable initial dilution (Dm = 36) for this outfall is 37:1. 3. Discharge Point 003 (Santa Ana River Overflow Weirs). Discharge Point 003 (i.e., the Santa Ana River Overflow Weirs) is comprised of two extreme emergency discharge points (overflow) to the tidal prism in the Santa Ana River, which eventually flows to the Pacific Ocean. One of the overflow points is located at the termination structure upstream of the EPSA facility and other one is at the OOBS facility. The structure consists of a 50' long overflow weir with two 72" pipes. The total capacity is approximately 605 MGD (i.e., 130 MGD from EPSA and 475 MGD from OOBS), but the actual capacity depends on the water level at the river. This outfall has never discharged over the past 10 years; however, it remains available for extreme emergency uses (e.g., tsunami, earthquake, flood, and acts of war or terrorism). Table F-2.

Compliance Summary Completion of Secondary Treatment Projects Since the construction of the facilities that was required to achieve secondary treatment standards were not completed at the time the previous permit was issued, OC San entered into a consent decree mandating OC San to meet secondary treatment limits by December 31, 2012. After extensive process improvement and Capital Improvement Projects (CIP) including completion of the following: • Trickling filter project at Reclamation Plant No. 1, completed in Spring 2006; • Secondary treatment rehabilitation project at Treatment Plant No. 2, completed in Spring 2008; • New trickling filters and solid contact basins at Treatment Plant No. 2, completed in Summer 2011. The project added 60 MGD of secondary treatment capacity; and • New activated sludge system at Reclamation Plant No. 1, completed in Fall 2012. The project added 60 MGD of secondary treatment capacity. The Discharger has officially declared the POTW at full secondary treatment on December 28, 2012 and continue operating at and meeting full secondary requirements. Cessation of Continuous Disinfection Practices at Discharge Point 001 (120" outfall The disinfection program initiated in 2002 was based on using sodium hypochlorite (bleach) for disinfection and sodium bisulfite for dechlorination. Beginning in 2006, the Discharger started to note negative changes in the structure and health of benthic communities within the zone of initial dilution (ZID) around the diffuser to the 120-inch ATTACHMENT F- FACT SHEET F-11 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS outfall (the primary discharge point). To determine the causes of these changes to the marine environment, the Discharger conducted detailed studies divided into two phases: Phase 1 (2009-2010) for an analysis of historical data to identify any potential causes and Phase 11 (2011-2012) for investigation of operational changes and process improvements that occurred at the treatment facilities and the facility's dry-weather urban runoff diversion program. Based on the results of these investigations, the discharge of chlorinated effluent prior to 2012 resulted in a decline in benthic communities near the ZID. The benthic environment has been improved since 2012 due to reduction of the use of chlorine after achieving full secondary treatment. After long-term beach water quality studies and oceanographic data evaluation by an Independent Advisory Panel (IAP) of experts hosted by the National Water Research Institute (NWRI), it was concluded that continuing to chlorinate full secondary treated effluent provides little to no public health benefit to local beaches. The Discharger has also achieved continuous compliance with the secondary treatment requirements of the Clean Water Act. On March 17, 2015, based on the observations and recommendations of the IAP and with public support, OC San received approval from the Santa Ana Regional Water Quality Control Board and USEPA to cease disinfection at Discharge Point 001 (120" outfall). OC San has ceased continuous chlorination/dechlori nation since May 2015. The disinfection system would remain available for later use, if determined necessary. Use of disinfection remains at the other two discharge points (Discharge Points 002 and 003) to protect human health. Planned 6-Week Diversion to Discharge Point 002 (78" outfall) From September 11, 2012 through October 4, 2012, the Discharger temporarily diverted disinfected effluent from Discharge Point 001 (120" outfall) to Discharge Point 002 (78" outfall) as part of an infrastructure rehabilitation project (refer to as Capital Improvement Project J-112) to inspect, assess, and rehabilitate the Outfall Land Section and Ocean Outfall Booster Pump Station Piping. To minimize impacts to public health, the treated wastewater received enhanced disinfection so that state bacterial water contact standards were met prior to discharge and subsequent dilution. The Discharger conducted the J-112 environmental monitoring program including modeling to track the discharged plume, measure the effectiveness of the enhanced disinfection program, and determine environmental impacts to the receiving water during the diversion to the nearshore outfall. The lessons learned report and a more comprehensive report (i.e., 2012 OCSD Outfall Diversion Summary Report) were submitted to the Santa Ana Water Board and USEPA on March 25, 2014, which summarize the sampling methodology during the diversion and provide recommendations for improving monitoring during any future diversions to Discharge Point 002 (78" outfall). Unintentional Bypass of primary effluent from Plant No. 2 to Discharge Point 001 (120" outfall) The unintentional bypass of primary effluent into Discharge Point 001 (120" outfall) occurred on July 5, 2020 from 4:28 am to 5:02 am, a duration of 34 minutes, due to a power loss after an Edison transformer failed. The power loss affected equipment ATTACHMENT F- FACT SHEET F-12 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS throughout Treatment Plant No. 2 including the trickling filter influent pumps. The trickling filter weir overflowed with primary treated wastewater, approximately 0.94 million gallons of which discharged directly to the 120" outfall. Another unanticipated bypass of primary effluent into the 120" outfall occurred at the same location due to failure of two of three lead pumps serving the trickling filters pump station (TFPS) during a wet weather event on December 28, 2020 at 7:09 pm for approximately 9 minutes. The estimated flow over the TFPS weir is total 78,500 gallons. After discovering each incident, the Discharger notified the Santa Ana Water Board and USEPA and investigated the incident to determine the cause and duration of the incident, the volume discharged, and to evaluate and implement appropriate corrective actions to prevent this incident from reoccurring. As part of corrective actions, the TFPS lead pumps were disassembled, and their internal fans replaced. As a key sustainable action, OC San is currently in construction installing an upgraded power monitoring/power management control system to improve the power system response speed to prevent short term power loss event that can lock out equipment. This project is scheduled to be complete by 2023. E. Planned Changes GWRS Final Expansion Protect The GWRS is a regional water reclamation program that was initiated jointly by OC San and OCWD and began operation in January 2008. The GWRS Initial Expansion was completed in 2015, which allowed OCWD to take up to 135 MGD of secondary effluent from Plant No. 1 to produce 100 MGD of GWRS product water. Currently, the Discharger sends approximately 100% of secondary effluent from Plant No. 1 to GWRS to provide a drought-proof water supply for Orange County. Also, it delivers up to 4 MGD of secondary effluent from Plant No. 1 to GAP during the summer months to provide recycled water for landscaped irrigation and industrial uses. The layout of the OCWD facilities has been designed to provide GWRS with an ultimate production capacity of 130 MGD. The GWRS ultimate production capacity of 130 MGD is referred to as the GWRS Final Expansion project. Based on the SP-173 Effluent Reuse Study for the evaluation of reclamation of Plant No. 2 effluent, the following projects are identified by the implementation plan for the GWRS Final Expansion and anticipated to be completed by 2023. • Modify Plant 2 Headworks Facility to create a reclaimable and non-reclaimable treatment train. Reclaimable flows will go through existing preliminary, primary, and secondary (trickling filter solids contact) treatment before being pumped to GWRS. • Build a Plant 2 effluent pump station that will convey approximately 50-85 MGD of secondary effluent from Plant No. 2 trickling filter solids contact process to the GWRS Facility. ATTACHMENT F- FACT SHEET F-13 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS • Build a 6 MG equalization storage tank at Plant No. 2 to store secondary effluent during peak day flows and be returned to the system during low flow periods to maintain a constant flow to the GWRS. • Relocate the existing plant water pump station to a location more suitable for receiving the trickling filter solids contact treatment processes. After the GWRS Final Expansion, the activated sludge treatment process will treat only SARI and side-stream flows. • Convert the unused 66-inch gravity reinforced concrete pipeline into a pressure pipeline using a trenchless pipe repair method, to convey the effluent pump station discharge. This expansion would require a total flow from OC San plants of approximately 175 MGD to produce 130 MGD of indirect potable reuse water. The Final Expansion of the GWRS will enable the Discharger to recycle the majority of the wastewater generated in its service area and treated at its two wastewater treatment plants. Organic Waste Co-Digestion Project Construction and operation of an organic waste co-digestion facility is anticipated to be completed in 2022. An organic waste receiving facility will be constructed to receive, store, and feed approximately 150 tons of pre-processed food waste slurry to the digester complex at Plant No. 2 (by Digester M) to generate additional digester gas per recommendations of the Biosolids Master Plan. This facility will be replaced with a permanent receiving station following completion of a proposed program to replace existing digesters at Plant No. 2. Food waste will be fed into OC San's digesters, creating more gas and electricity, while producing a few extra truckloads of solids per week. III. APPLICABLE PLANS, POLICIES, AND REGULATIONS The requirements contained in this Order are based on the requirements and authorities described in this section. A. Legal Authorities This Order serves as WDRs pursuant to article 4, chapter 4, division 7 of the California Water Code (CWC) (commencing with section 13260). This Order/Permit is also issued pursuant to section 402 of the federal Clean Water Act (CWA) and implementing regulations adopted by the USEPA and chapter 5.5, division 7 of the Water Code (commencing with section 13370). This Order shall serve as an NPDES permit for point source discharges from this POTW to waters of the United States. The Order/Permit are consolidated pursuant to 40 CFR. § 124.4(c)(2). Although Discharge Point 001 is beyond the limit of State-regulated ocean waters, effluent plume migration into State waters warrants joint regulation of the discharge by USEPA and the Santa Ana Water Board.

California Environmental Quality Act (CEQA) Under Water Code section 13389, this action to adopt an NPDES permit is exempt from the provisions of Chapter 3 of CEQA, (commencing with section 21100) of Division 13 of the Public Resources Code. C. State and Federal Laws, Regulations, Policies, and Plans 1. Water Quality Control Plan. The Santa Ana Regional Water Quality Control Board adopted a Water Quality Control Plan for the Santa Ana River Basin (hereinafter Basin Plan) in 1995, that designates beneficial uses, establishes water quality objectives, and contains implementation programs and policies to achieve those objectives for the Offshore Zone and Nearshore Zone of the Pacific Ocean and the tidal prism of the Santa Ana River. In addition, the Basin Plan implements State Water Resources Control Board (State Water Board) Resolution No. 88-63 which established State policy that all waters, with certain exceptions, should be considered suitable or potentially suitable for municipal or domestic supply. Requirements in this Order/Permit implement the Basin Plan. Basin Plan beneficial uses applicable to the Pacific Ocean and/or the Santa Ana River tidal prism are as follows: Table F-5. Basin Plan Beneficial Uses Discharge Receiving Water Beneficial Use(s) Point Name Pacific Ocean, Offshore Zone: Industrial service supply; navigation; 001 water contact recreation; non-contact water (120" outfall) Beyond the limit of State waters recreation; commercial and sportfishing; wildlife habitat; rare, threatened, or endangered species; spawning, reproduction, and development; and 002 Pacific Ocean, marine habitat. (78" outfall) Offshore Zone Nearshore Zone: Industrial service supply; navigation; water contact recreation; non-contact water recreation; commercial and sportfishing; wildlife 003 habitat; rare, threatened, or endangered species; Santa Ana River spawning, reproduction, and development; marine (Santa Ana Tidal Prism, habitat; and shellfish harvesting. River overflow Reach 1 Santa Ana River, Reach 1: Water contact recreation weirs) (access prohibited); non-contact water recreation; warm freshwater habitat; and wildlife habitat. 2. California Ocean Plan. The State Water Board adopted the Water Quality Control Plan for Ocean Waters of California, California Ocean Plan (hereinafter Ocean Plan) in 1972 and amended it in 1978, 1983, 1988, 1990, 1997, 2000, 2005, 2009, 2012, 2015, 2018, and 2019. The Ocean Plan is applicable, in its entirety, to point source discharges to the ocean. The Ocean Plan identifies ATTACHMENT F- FACT SHEET F-15 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS beneficial uses of ocean waters of the state to be protected as summarized below: Table F-6. Ocean Plan Beneficial Uses Discharge Receiving Beneficial Uses Point Water Industrial water supply; water contact and non-contact recreation, including aesthetic enjoyment; navigation; 001 and 002 Pacific Ocean commercial and sport fishing; mariculture; preservation and enhancement of designated Areas of Special Biological Significance (ASBS); rare and endangered species; marine habitat; fish spawning and shellfish harvesting In order to protect the beneficial uses, the Ocean Plan establishes water quality objectives and a program of implementation. Requirements of this Order/Permit implement the Ocean Plan. 3. California Thermal Plan. The State Water Board adopted the Water Quality Control Plan for Control of Temperature in the Coastal and Interstate Waters and Enclosed Bays and Estuaries of California (hereinafter Thermal Plan) on January 7, 1971, and amended this plan on September 18, 1975. This plan contains temperature objectives for coastal and inland surface waters. Requirements of this Order/Permit implement the Thermal Plan. 4. Antidegradation Policy. Federal regulation 40 CFR § 131.12 requires that the state water quality standards include an antidegradation policy consistent with the federal policy. The State Water Board established California's antidegradation policy in State Water Board Resolution 68-16 ("Statement of Policy with Respect to Maintaining High Quality of Waters in California"). Resolution 68-16 is deemed to incorporate the federal antidegradation policy where the federal policy applies under federal law. Resolution 68-16 requires that existing water quality be maintained unless degradation is justified based on specific findings. The Santa Ana Regional Water Quality Control Board's Basin Plan implements, and incorporates by reference, both the state and federal antidegradation policies. The permitted discharge must be consistent with the antidegradation provision of section 131.12 and State Water Board Resolution 68-16. 5. Anti-Backsliding Requirements. Sections 402(o) and 303(d)(4) of the CWA and federal regulations at 40 CFR § 122.44(I) restrict backsliding in NPDES permits. These anti-backsliding provisions require that effluent limitations in a reissued Order/Permit must be as stringent as those in the previous Order/Permit, with some exceptions in which limitations may be relaxed. 6. Alaska Rule. USEPA has revised its regulation that specifies when new and revised State and tribal water quality standards become effective for CWA purposes. (40 CFR § 131.21; 65 Fed. Reg. 24641 (April 27, 2000).) Under the revised regulation (also known as the Alaska Rule), new and revised standards ATTACHMENT F- FACT SHEET F-16 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS submitted to USEPA after May 30, 2000 must be approved by USEPA before being used for CWA purposes. The final rule also provides that standards already in effect and submitted to USEPA by May 30, 2000, may be used for CWA purposes, whether or not approved by USEPA. 7. Section 403(c) of the Clean Water Act (CWA): Discharges to marine waters are subject to Section 403 of the CWA, which sets forth criteria to prevent unreasonable degradation of the marine environment and authorized imposition of any additional effluent limits necessary to protect the marine environment. Pursuant to 40 CFR § 125.122, unreasonable degradation of the marine environment is evaluated based on ten factors or based on the application of a state's water quality standards. Specifically, 40 CFR § 125.122(b) states that discharges in compliance with State water quality standards "shall be presumed not to cause unreasonable degradation of the marine environment, for any specific pollutants or conditions specified in the variance or the standard." USEPA and the Santa Ana Water Board are applying the Basin Plan and the Ocean Plan as specified in section III.C.1 and 2 of this Fact Sheet, except for evaluating acute/chronic toxicity for Discharge Points 001 and 002 using the TST statistical approach. USEPA has reviewed the previous studies to examine the comparison of toxicity test results using the TST and NOEC statistical approaches and has determined that use of the TST statistical approach is consistent with the Ocean Plan and CWA § 403(c) in that it provides protection of the designated beneficial uses of ocean waters. TST statistical approach is also used in other NPDES permits for large publicly owned treatment works, including City of Los Angeles. Given the available dilution (i.e. 180), the receiving water monitoring requirements, the Discharger's analysis of the ocean discharge criteria as part of its application (See Appendix E.1 Ocean Discharge Criteria Response to CWA 403(c)), and USEPA's additional 403(c) analysis, USEPA makes a determination that the discharges authorized in this permit will not cause unreasonable degradation of the marine environment. 8. Federal Permit Renewal Contingency. The renewal of the Discharger's federal permit by USEPA is contingent upon determination by the U.S. Fish and Wildlife Service (USFWS) and NOAA National Marine Fisheries Service (NMFS) that the proposed discharge is consistent with the: (1) federal Endangered Species Act (ESA); (2) the Magnuson-Stevens Fishery Conservation and Management Act (MSA); and (3) the Santa Ana Water Board's certification/concurrence that the discharge will comply with applicable State water quality standards. USEPA's reissuance of NPDES No. CA0110604 to OC San is subject to requirements of the ESA and MSA. USEPA may decide that changes to this permit are warranted based on the results of the completed consultation and a reopener provision to this effect has been included in the Order/Permit. Issuance of this NPDES permit which incorporates both federal requirements and State waste discharge requirements will serve as the State's concurrence that the discharge complied with State water quality standards. The California Coastal Commission has indicated that it is not necessary to obtain a consistency ATTACHMENT F- FACT SHEET F-17 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS certification pursuant to the Coastal Zone Management Act for the issuance of a federal NPDES permit containing secondary treatment standards. 9. Endangered Species Act Requirements. This Order/Permit does not authorize any act that results in the taking of a threatened or endangered species or any act that is now prohibited, or becomes prohibited in the future, under either the California Endangered Species Act (Fish and Game Code, §§ 2050 to 2097) or the Federal Endangered Species Act (16 U.S.C.A. §§ 1531 to 1544). In July 2020, USEPA requested updated information related to: (1) essential fish habitat and managed and associated species, and (2) threatened and endangered species and their designated critical habitats, in the vicinity of the OC San's outfalls from NMFS. Subsequently, EPA and NMFS exchanged information about the facility, discharge characteristics, action area, OC San's monitoring program, and past consultations in Southern California. USEPA determined that the draft permit would have no effect on listed bird species; may affect but is not likely to adversely affect listed fish and abalone species; and is likely to adversely affect listed sea turtle, seal, and whale species. These effect determinations are explained in the biological evaluation. USEPA is consulting with the United States Fish and Wildlife Service and the National Marine Fisheries Service. This Order/Permit requires compliance with effluent limits, receiving water limits, and other requirements to protect beneficial uses, including protecting threatened and endangered species. The Discharger is responsible for meeting all requirements of the applicable Endangered Species Act. D. Impaired Water Bodies on the CWA section 303(d) List On April 6, 2018, USEPA issued a final decision regarding California's 2014- 2016 CWA Section 303(d) List of Impaired Waters. The list (hereinafter 303(d) list) identifies water bodies where water quality standards are not expected to be met after implementation of technology-based effluent limits by point sources. Huntington Beach State Park is included on the 303(d) list for PCBs (polychlorinated biphenyls). The offshore and nearshore zones off Huntington Beach State Park are the immediately affected receiving waters of discharges from the Facility. A total maximum daily load (TMDL) for PCBs is required but has not been established yet. As such, effluent limitations for PCBs have been established for the Facility until applicable waste load allocations are assigned in a TMDL. A TMDL to address the impairment is not currently scheduled for development. E. Other Plans, Polices and Regulations 1. Stringency of Requirements for Individual Pollutants. This Order/Permit contains technology-based effluent limitations and WQBELs for individual pollutants. Technology-based effluent limitations consist of restrictions on carbonaceous biochemical oxygen demand (5-day), total suspended solids, and pH which implement the minimum, applicable federal technology-based requirements for POTWs. Also, effluent limitations consisting of restrictions on oil and grease, settleable solids, and turbidity are necessary to implement State treatment standards in Ocean Plan Table 4. Discharge Point 001 WQBELs ATTACHMENT F- FACT SHEET F-18 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS consisting of restrictions on total chlorine residual, acute toxicity, chronic toxicity, radioactivity, benzidine, hexachlorobenzene, PCBs, TCDD equivalents, and toxaphene more stringent than federal technology-based limitations are necessary to meet State water quality standards in the Ocean Plan Table 3. Discharge Point 002 WQBELs consisting of restrictions on fecal coliform density, Enterococcus density, total chlorine residual, ammonia (as nitrogen), chronic toxicity, radioactivity, and TCDD equivalents more stringent than federal technology-based limitations are necessary to meet State water quality standards in the Ocean Plan Table 3. All effluent limitations are discussed in Attachment F-Fact Sheet. Collectively, the restrictions on individual pollutants in this Order/Permit are no more stringent than required by the CWA. 2. Federal Secondary Treatment Regulations. The OC San achieved full secondary treatment on December 28, 2012 and continues discharging secondary treated flow. 40 CFR § 133 establishes the minimum levels of effluent quality to be achieved by secondary treatment. These limitations, established by USEPA, are incorporated into this Order/Permit, except where more stringent limitations are required by other applicable plans, policies, or regulations or to prevent backsliding. 3. Industrial Storm Water Requirements. The Discharger is not required to be covered under the statewide NPDES general permit for storm water discharges associated with industrial activities (NPDES General Permit No. CAS000001) because all stormwater at the plants is collected by various drains and conveyed downstream of both plants' headworks for treatment. No storm water is diverted untreated to the outfalls. The Discharger has provided certification to the Santa Ana Water Board and USEPA that industrial storm water is managed by internal drainage systems at Reclamation Plant No. 1 and Treatment Plant No. 2, where storm water is captured, treated, and discharged with the treated wastewater regulated under this Order/Permit. This Order/Permit requires the Discharger to submit and implement a Storm Water Management Plan to address onsite storm water quality. 4. Sanitary Sewer Overflows. The State Water Board issued General Waste Discharge Requirements for Sanitary Sewer Systems, Water Quality Order 2006- 0003-DWQ (General Order) on May 2, 2006, which contains requirements for operation and maintenance of collection systems and for reporting and mitigating sanitary sewer overflows (SSOs). The Monitoring and Reporting Program for the General Order was amended through the State Water Board's Order WQ 2013- 0058-EXEC on August 6, 2013. This General Order requires public agencies that own or operate sanitary sewer systems with greater than one mile of pipes or sewer lines to enroll for coverage under the General Order. The General Order also requires agencies to develop sanitary sewer management plans and report all SSOs, among other requirements and prohibitions. The Discharger's collection system is part of the POTW that is subject to this Order/Permit. The Discharger must comply with both the General Order and this Order/Permit. ATTACHMENT F- FACT SHEET F-19 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS 5. Pretreatment Requirements. In compliance with 40 CFR § 403, OC San has developed an approved Pretreatment Program for the POTW that it owns and operates. This Order/Permit includes the Discharger's approved Pretreatment Program and requires the Discharger to continue implementation and control of the Program throughout the service area of its POTW, including contributing jurisdictions. The POTW, as Control Authority, may exercise its authority over the entire service area directly, as provided by State law, or may elect to enter into contracts or other multi-jurisdictional agreements with contributing jurisdictions. In case the POTW elects to enter into inter-jurisdictional agreements, the POTW must ensure that discharges received from entities outside of its political boundaries are regulated to the same extent as are discharges within its political boundaries. OC San applies one set of local limits to all discharges to its treatment facilities. 6. Sewage Sludge/Biosolids Requirements. Section 405 of the CWA and implementing regulations at 40 CFR § 503 require that producers of sewage sludge/biosolids meet certain reporting, handling, and use or disposal requirements. The State has not been delegated the authority to implement this program; therefore, USEPA is the implementing agency. This Order/Permit contains sewage sludge/biosolids requirements pursuant to 40 CFR § 503 that are applicable to the Discharger. 7. Standard and Special Provisions. Standard Provisions, which apply to all NPDES permits in accordance with 40 CFR § 122.41, and additional conditions applicable to POTWs in accordance with 40 CFR § 122.42, are provided in Attachment D. The Santa Ana Water Board and USEPA have also included in this Order/Permit Special Provisions applicable to the Discharger. The rationale for the Special Provisions contained in this Order/Permit is provided in this Fact Sheet. IV. RATIONALE FOR EFFLUENT LIMITATIONS AND DISCHARGE SPECIFICATIONS The CWA requires point source dischargers to control the amount of conventional, non- conventional, and toxic pollutants that are discharged into the waters of the United States. The control of pollutants discharged is established through effluent limitations and other requirements in NPDES permits. There are two principal bases for effluent limitations in the Code of Federal Regulations: 40 CFR § 122.44(a) requires that permits include applicable technology-based limitations and standards; and 40 CFR § 122.44(d) requires that permits include water quality-based effluent limitations to attain and maintain applicable numeric and narrative water quality criteria to protect the beneficial uses of the receiving water. A. Discharge Prohibitions Discharge Prohibitions in this Order/Permit are based on Ocean Plan discharge prohibitions, Basin Plan discharge prohibitions, and discharge prohibitions in the existing Order/Permit. ATTACHMENT F- FACT SHEET F-20 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS 1. California Ocean Plan Discharge Prohibitions a. Prohibition 1113, III.C, III.D, III.E, and III.F: This permit/order implements discharge prohibitions that are applicable under sections 111.1.1.a, 111.1.2.a, 111.1.3.a, 111.1.4.a, and 111.1.6 of the 2019 California Ocean Plan, respectively. b. Prohibition III.G (Discharge at Discharge Point 001 without minimum initial dilution of at least 181:1): This prohibition is necessary to ensure that the assumption used to derive the dilution credits established through this Order/Permit remains substantially the same so that the effluent limitations are protective of water quality. This Order considered a dilution credit of 180 (Dm = 180) based on the Discharger's GWRS Final Expansion Final Implementation Plan, Project No. SP-173, Effluent Reuse Study (October 2016) to conduct the reasonable potential analysis described in Section IV.C.3 of this Fact Sheet. Moreover, the instream waste concentration (IWC) for the chronic toxicity effluent limitation is based on this dilution credit. When future discharge flows drop below 32 MGD, as a result of GWRS final expansion project, the outfall will likely need to be retrofitted to ensure adequate dilution and to prevent seawater intrusion and potential diffuser plugging. The initial dilution of 181:1 assumes that all 503 outfall ports are operational. 2. Santa Ana River Basin Plan Discharge Prohibitions a. Prohibition III.H, 111.1, and III.J: This permit/order implements discharge prohibitions that are applicable under Chapter 5, Waste Discharge Prohibitions A, B.1, and B.2 of the 2019 Basin Plan, respectively. 3. Prohibition III.K (Discharge from any locations other than Discharge Point 001): This prohibition clarifies that any discharges other than those to Discharge Point 001 are unauthorized, except those to Discharge Point Nos. 002 and 003 as explicitly authorized during essential maintenance or an emergency. B. Technology-Based Effluent Limitations (TBELs) 1. Scope and Authority Section 301(b) of the CWA and implementing USEPA permit regulations at 40 CFR § 122.44 require that permits include conditions meeting applicable technology-based requirements at a minimum, and any more stringent effluent limitations necessary to meet applicable water quality standards. The discharge authorized by this Order/Permit must meet minimum federal technology-based effluent limitations (TBELs) based on secondary treatment standards for POTWs at 40 CFR § 133. The CWA requires that technology-based effluent limitations be established based on several levels of controls: a. Best practicable treatment control technology (BPT) represents the average of the best existing performance by well-operated facilities within an industrial ATTACHMENT F- FACT SHEET F-21 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS category or subcategory. BPT standards apply to toxic, conventional, and non-conventional pollutants. b. Best available technology economically achievable (BAT) represents the best existing performance of treatment technologies that are economically achievable within an industrial point source category. BAT standards apply to toxic and non-conventional pollutants. c. Best conventional pollutant control technology (BCT) represents the control from existing industrial point sources of conventional pollutants including BOD, TSS, fecal coliform, pH, and oil and grease. The BCT standard is established after considering a two-part reasonableness test. The first test compares the relationship between the costs of attaining a reduction in effluent discharge and the resulting benefits. The second test examines the cost and level of reduction of pollutants from the discharge from publicly- owned treatment works to the cost and level of reduction of such pollutants from a class or category of industrial sources. Effluent limitations must be reasonable under both tests. d. New source performance standards (NSPS) represent the best available demonstrated control technology standards. The intent of NSPS guidelines is to set limitations that represent state-of-the-art treatment technology for new sources. The CWA requires USEPA to develop effluent limitations, guidelines and standards (ELGs) representing application of BPT, BAT, BCT, and NSPS. Section 402(a)(1) of the CWA and 40 CFR § 125.3 authorize the use of best professional judgment (BPJ) to derive technology-based effluent limitations on a case-by-case basis where ELGs are not available for certain industrial categories and/or pollutants of concern. Where BPJ is used, the Santa Ana Water Board and USEPA must consider specific factors outlined in 40 CFR § 125.3. Regulations promulgated in 40 CFR § 125.3(a)(1) require technology-based effluent limitations for municipal Dischargers to be placed in NPDES permits based on Secondary Treatment Standards or Equivalent to Secondary Treatment Standards. The Federal Water Pollution Control Act Amendments of 1972 (PL 92-500) established the minimum performance requirements for POTWs [defined in section 304(d)(1)]. Section 301(b)(1)(B) of that Act requires that such treatment works must, as a minimum, meet effluent limitations based on secondary treatment as defined by the USEPA Administrator. Based on this statutory requirement, USEPA developed secondary treatment regulations, which are specified in 40 CFR § 133. These technology-based regulations apply to all municipal wastewater treatment plants and identify the minimum level of effluent quality attainable by secondary treatment in terms of biochemical oxygen demand (BOD5), total suspended solids (TSS), and pH. ATTACHMENT F- FACT SHEET F-22 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS Table F-7.

In the 2004 Order/Permit, CBOD5 effluent limitations were applied to the final effluent during partial or full nitrification at the Discharger's secondary treatment facilities, where effluent nitrification is used to reduce ammonia toxicity associated with wastewater treatment and RO concentrate flow from the Groundwater Replenishment System. As nitrifying bacteria use oxygen to degrade nitrogenous compounds otherwise not significantly removed in the secondary treatment process, higher oxygen demand values for the final effluent result. Consequently, the use of CBOD5 effluent limits have been found to ensure that federal secondary treatment standards for POTWs are achieved while allowing the Discharger to use the treatment process of nitrification to reduce ammonia toxicity in the discharged effluent and comply with Ocean Plan requirements for acute and chronic toxicity. CBOD5 effluent limitations have been carried over to this Order/Permit and are applied in lieu of BOD5 effluent limitations. The effluent limitations consisting of restrictions on grease and oil, settleable solids, and turbidity are necessary to implement State treatment standards in Ocean Plan Table 4, which are summarized as follows.

The 2012 Order/Permit established mass emission effluent limitations based on the average daily influent flow projected for 2017 (i.e., 274 MGD). For Discharge Point 001, this Order/Permit establishes mass emission effluent limitations for TBELs based on the average daily upper bound influent flow of 206 MGD projected for 2025, taken from the Discharger's 2017 Master Plan. For Discharge Point 002, mass emission effluent limitations for TBELs continue to be based on the Discharger's conservative estimate for hydraulic flow capacity of the 78-inch outfall of 230 MGD. 2. Applicable Technology-Based Effluent Limitations A summary of the applicable technology-based effluent limitations is shown in Tables F-14 and F-15, in section IV.E of this Fact Sheet. C. Water Quality-Based Effluent Limitations (WQBELs) 1. Scope and Authority CWA Section 301(b) and 40 CFR § 122.44(d) require that NPDES permits include limitations more stringent than applicable federal technology-based requirements where necessary to achieve applicable water quality standards and State requirements. Section 122.44(d)(1)(i) of 40 CFR requires that permits include effluent limitations for all pollutants that are or may be discharged at levels that have the reasonable potential to cause or contribute to an exceedance of a water quality standard, including numeric and narrative objectives within a standard. Where reasonable potential has been established for a pollutant, but there is no numeric criterion or objective for the pollutant, water quality-based effluent limitations (WQBELs) must be established using: (1) USEPA criteria guidance under CWA section 304(a), supplemented where necessary by other relevant information; (2) an indicator parameter for the pollutant of concern; or (3) a calculated numeric water quality criterion, such as a proposed state criterion or policy interpreting the state's narrative criterion, supplemented with other relevant information, as provided in section 122.44(d)(1)(vi). USEPA has applied CWA section 403(c) and 40 CFR § 125, Subpart M, following 40 CFR § 122. The process for determining reasonable potential and calculating WQBELs when necessary is intended to protect the designated uses of the receiving water as specified in the Basin Plan, and achieve applicable water quality objectives and ATTACHMENT F- FACT SHEET F-24 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS criteria that are contained in other state plans and policies, or any applicable water quality criteria contained in the Ocean Plan. 2. Applicable Beneficial Uses and Water Quality Criteria and Objectives The Basin Plan and Ocean Plan designate beneficial uses, establish water quality objectives, and contain implementation programs and policies to achieve those objectives for all waters of the State. Applicable beneficial uses designated within the Basin Plan and Ocean Plan are listed in Tables F-5 and F-6, in section III.0 of this fact sheet. The Basin Plan contains Water Quality Objectives for bacteria for water bodies designated for water contact recreation. The Ocean Plan establishes applicable water quality objectives for the protection of marine aquatic life and human health. The Ocean Plan also includes water quality objectives for bacterial characteristics, physical characteristics, chemical characteristics, biological characteristics, and radioactivity. The water quality objectives from the Ocean Plan and Basin Plan were incorporated into this Order/Permit as either final effluent limitations (based on reasonable potential) or receiving water limitations. 3. Determining the Need for WQBELs a. RPA Methodology The 2012 Order/Permit (Order No. R8-2012-0035) contains WQBELs for pollutant parameters based on Table B of the 2009 Ocean Plan. For this Order/Permit, the need for WQBELs based on water quality objectives in Table 3 of the 2019 Ocean Plan was statistically reevaluated in accordance with the Reasonable Potential Analysis (RPA) procedures contained in Appendix VI of the 2019 Ocean Plan. The statistical RPA method accounts for the averaging period of the water quality objective, accounts for and captures the long-term variability of the pollutant in the effluent, accounts for limitations associated with sparse data sets, accounts for uncertainty associated with censored data sets, and assumes a lognormal distribution of the facility-specific effluent data. The program calculates the upper confidence bound (UCB) of an effluent population percentile after complete mixing. In the evaluation employed in this Order/Permit, the UCB is calculated as the one-sided, upper 95 percent confidence bound for the 95th percentile of the effluent distribution after complete mixing. The calculated UCB95/95 is then compared to the appropriate water quality objective to determine the potential for an exceedance of that objective and the need for a WQBEL. For constituents that have an insufficient number of monitoring data or a substantial number of non- detected data with a reporting limit higher than the respective water quality objective, the RPA result is likely to be inconclusive. According to the Ocean Plan RPA procedure, the RPA can yield three endpoints: ATTACHMENT F- FACT SHEET F-25 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS Endpoint 1: An effluent limitation must be developed, and effluent monitoring for the pollutant is required; Endpoint 2: An effluent limitation is not required, but the Santa Ana Water Board and/or USEPA may require monitoring for the pollutant or for the whole effluent toxicity (WET) as appropriate; or Endpoint 3: The RPA is inconclusive, and monitoring for the pollutant or WET testing is required. An existing effluent limitation shall remain in the permit, otherwise a permit reopener clause shall be included to allow for subsequent modification of the permit to include an effluent limitation if the monitoring establishes that the discharge causes, has the reasonable potential to cause, or contributes to an excursion above the appropriate water quality objective. b. Minimum Initial Dilution or Dilution Credits The Discharger updated its dilution analysis as part of the planning process for the GWRS final expansion project (GWRS Final Expansion Final Implementation Plan, Project No. SP-173, Effluent Reuse Study, October 2016). The updated modeling included calibrating current conditions with the modeling completed in 2002 and 2008. The updated modeling continued to use NRFIELD in Visual Plumes, consistent with the past modeling. The analysis included various scenarios for flow rates, including low effluent flows as the result of the GWRS final expansion project, densities (i.e. temperature and salinity changes based on low effluent flows), and critical stratification conditions (i.e. August to October 2014). The analysis shows that dilution is unlikely to be impacted by the increase in RO concentrate discharged because the total discharge flow will be decreased. As to be expected, model results were the most sensitive to discharge flow rate and stratification and ranged from 151 :1 to 363:1 for the various scenarios. Based on the updated modeling, the Santa Ana Water Board and USEPA is carrying over the dilution ratio of 181:1, as this dilution (Dm = 180) is a representative of reasonable worst-case scenario (i.e. high discharge flow rate under strong stratified conditions) and is consistent with antidegradation and anti- backsliding requirements. With exception of radioactivity, the dilution ratio of 181 :1 (Dm = 180) has been applied to the final effluent limitations for Discharge Point No. 001 . The dilution ratio of 37:1 (Dm = 36) also has retained for Discharge Point No. 002 in this Order/Permit. Based on the Ocean Plan, water quality objectives for radioactivity shall apply directly to the undiluted waste effluent (i.e., Dm = 0 for radioactivity). c. RPA for Pollutants in Table 3 of the Ocean Plan RPAs were conducted using the State Water Board's RPcalc 2.0 software tool and minimum probable initial dilution values for Discharge Point 001 (i.e., Dm = 180) and Discharge Point 002 (i.e., Dm = 36), except for radioactivity.

CA0110604 COLLECTION SYSTEM & OUTFALLS Effluent data provided in the Discharger's monitoring reports from May 2015 to December 2019, after the Discharger achieved full secondary treatment and ceased disinfection, were used in the analyses in order to be representative of current performance. The results of these RPAs are summarized in Table F-9 for Discharge Point 001 (120" outfall) and Table F- 10 for Discharge Point 002 (78" outfall). Based on the RPA for Discharge Point 001, Endpoint 1 is established for total chlorine residual. Consequently, WQBELs for total chlorine residual are included in the Order/Permit and periodic effluent monitoring is also required. The Discharger ceased continuous effluent disinfection using chlorination/dechlorination at Discharge Point 001 (120" outfall). However, sodium hypochlorite has been used as oxidant chemical to treat foul air (i.e., HzS control) in scrubbers at primary treatment process and to control the bulking from filamentous organisms in the return activated sludge (RAS), which probably causes RP for total chlorine residual. Endpoint 2 is established for the majority of detected Table 3 pollutants. Consequently, WQBELs for these pollutants are not included in the Order/Permit, but periodic effluent monitoring for all Endpoint 2 pollutants is required. Endpoint 3 with inconclusive results was reported for benzidine, hexachlorobenzene, PCBs, TCDD equivalents, and toxaphene. Consequently, existing WQBELs for these five pollutants are retained in this Order/Permit and periodic effluent monitoring is also required. This Order/Permit does not include effluent limitations for other pollutants displaying Endpoint 3; instead, monitoring requirements for those pollutants were included. Based on the RPA for Discharge Point 002, Endpoint 1 is established for ammonia (as nitrogen), and total chlorine residual. Consequently, WQBELs for ammonia and total chlorine residual are included in the Order/Permit and periodic effluent monitoring is also required. Endpoint 2 is established for the majority of detected Table 3 pollutants. Consequently, WQBELs for these pollutants are not included in the Order/Permit, but periodic effluent monitoring for all Endpoint 2 pollutants is required. Endpoint 3 with inconclusive results was reported for TCDD equivalents and thus, existing WQBELs and quarterly effluent monitoring for TCDD equivalents are retained in this Order/Permit. This Order/Permit does not include effluent limitations for other pollutants displaying Endpoint 3; instead, monitoring requirements for those pollutants were included. Step 13 of the RPA procedures in the Ocean Plan authorizes RPA based on best professional judgment (BPJ). Information may include the facility type, discharge type, solids loading analysis, lack of dilution, history of compliance problems, potential toxic impact of discharge, fish tissue residue data, water quality and beneficial uses of the receiving water, CWA 303(d) listing for the pollutant, the presence of endangered or threatened species or critical habitat, and other information. Based on Step 13 of the Ocean Plan (i.e., BPJ), reasonable potential for acute and chronic toxicity has been established ATTACHMENT F- FACT SHEET F-27 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS for Discharge Point 001 and chronic toxicity for Discharge Point 002 because toxicity levels at POTWs can exceed applicable water quality standards, and numerical water quality objectives/criteria for the majority of chemical pollutants have not been established. In addition, reasonable potential for radioactivity has been established for Discharge Points 001 and 002 because POTWs accept waste from various facilities, including hospitals that could potentially discharge radioactivity into the sewershed, and the Discharger's wastewater treatment plants are not typically designed to remove radioactivity from the effluent. The discharge also had detectable concentrations of radioactivity (i.e., maximum effluent concentration (MEC) for gross alpha of 36 pCi/L and MEC for gross beta of 70 pCi/L). Thus, WQBELs for acute/chronic toxicity and radioactivity at Discharge Point 001 and a WQBLEL for chronic toxicity and radioactivity at Discharge Point 002 are included in this Order/Permit.

Concentration-based WQBEL Calculations From the Table 3 water quality objectives in the 2019 Ocean Plan, concentration-based WQBELs are calculated according to the following equation for all pollutants, except for acute and chronic toxicity (if applicable): Ce = Co + DM(Co — Cs) Where, Ce = the effluent limitation Co = the water quality objective to be met at the completion of initial dilution CS = background seawater concentration (see Table F-11 below) DM = minimum probable initial dilution expressed as parts seawater per part wastewater (i.e., 180 for Discharge Point 001 and 36 for Discharge Point 002) Background seawater concentration for all Table 3 pollutants is assumed to be zero (Cs = 0), except for the following five pollutants: Table F-11.

All calculations are based on discharge through Discharge Point 002 and, therefore, a dilution ratio (Dm) of 36 is applied. Example - Copper Ce = 3 + 36 (3 — 2) = 39 µg/L (6-month Median) Ce = 12 + 36 (12 — 2) = 372 µg/L (Maximum Daily) Ce = 30 + 36 (30 — 2) = 1,038 µg/L (Instantaneous Maximum) Total Chlorine Residual Ce = 2 + 36 (2 — 0) = 74 µg/L (6-month Median) Ce = 8 + 36 (8 — 0) = 296 µg/L (Maximum Daily) Ce = 60 + 36 (60 — 0) = 2,220 µg/L (Instantaneous Maximum) Ammonia Ce = 0.6 + 36 (0.6 — 0) = 22.2 mg/L (6-month Median) Ce = 2.4 + 36 (2.4 — 0) = 88.8 mg/L (Maximum Daily) Ce = 6 + 36 (6 — 0) = 222 mg/L (Instantaneous Maximum) TCDD equivalents Ce = 3.9x10-9 + 36 (3.9X10-9 — 0) = 144.3x10-9 µg/L = 0.144 pg/L (Average Monthly) b. Mass-based WQBEL Calculations The following equation from the 2019 Ocean Plan Chapter III.C.4.j is used to calculate all mass-based WQBELs. Mass (in Ibs/day) = 0.00834 x Ce x Q where: Ce = the effluent concentration limitation (µg/L) Q = flow rate (MGD) For example, in the case of PCBs where Q = 206 MGD for Discharge Point 001, the average monthly mass-based WQBEL is: Ce = 0.00834 x 0.0034 µg/L x 206 MGD = 0.0058 Ibs/day For Discharge Point 001 (120" outfall), the previous Order/Permit established mass emission effluent limitations based on the average daily influent flow (Q) of 274 MGD projected for 2017. This Order/Permit establishes mass emission effluent limitations based on the average daily upper bound influent flow of 206 MGD projected for 2025, which was taken from the Discharger's 2017 Master Plan.

Since Discharge Point 002 is authorized for emergency situations, it is anticipated to use its maximum hydraulic flow capacity of 230 MGD during emergency discharges. C. Bacteria WQBEL Calculations Bacteria effluent limitations for Discharge Point 002 remain in the Order/Permit to ensure protection of human health and receiving water quality for REC-1 beneficial uses and compliance with REC-1 water quality objectives for bacteria in the Pacific Ocean. The Ocean Plan was amended in 2018 to revise the bacterial objectives for ocean waters used for water contact recreation, which includes removal of the previously established total coliform objectives and the revised enterococci objectives based on the EPA 2012 Recreational Criteria for marine waters. This Order/Permit has established bacteria effluent limitations at Discharge Point 002 (78" outfall) based on the amended water quality objectives in Table 1 and 2 of the 2019 Ocean Plan. Fecal coliform and enterococcus WQBELs for Discharge Point 002 are determined using the equation, Ce=Co+Dm(Co-CS) and an Initial dilution of 37:1 (Dm=36). The background conditions for fecal coliform and enterococcus are assumed to be zero. Table F-13.

Whole Effluent Toxicity (WET) Whole Effluent Toxicity (WET) testing protects receiving waters from the aggregate toxic effect of a mixture of pollutants in the effluent or pollutants that are not typically monitored. An acute toxicity test is conducted over a short time period and measures mortality. A chronic toxicity test is conducted over a short or a longer period of time and measures a sublethal endpoint such as reproduction or growth, and sometimes mortality. Because of the nature of industrial discharges and contaminants of emerging concern (CEC) used in households such as PPCPs, pesticides and PFAS which may be released into the POTW sewershed, toxic constituents in and of itself or in combination may be present in the effluent. A total of 71 chronic and 26 acute WET tests was conducted on the effluent discharged to Discharge Point 001 (120" outfall) between May 2015 and December 2019. None of the testing results was reported as "Fail" for both acute and chronic toxicity. However, based on Step 13 of the RPA procedures in the Ocean Plan (i.e., best professional judgement), reasonable potential for acute and chronic toxicity has been established for Discharge Point 001 and chronic toxicity for Discharge Point 002 due to potentially toxic chemicals exceeding water quality standards and numerous chemicals having no specific water quality standard. Therefore, the protection of aquatic life through the evaluation of toxicity monitoring is necessary to examine the potential for the individual and/or combination of toxic chemicals that pass through the POTW. The Ocean Plan addresses the application of chronic and acute toxicity requirements based on minimum probable initial dilutions (Dm) for ocean discharges. Following the Ocean Plan, dischargers are required to conduct chronic toxicity monitoring for ocean discharges with Dm factors ranging from 99 to 349; also, Santa Ana Water Boards or USEPA may require acute toxicity monitoring in addition to chronic toxicity monitoring. Dischargers with Dm factors below 99 are required to conduct only chronic toxicity testing. Since the Dm for Discharge Point 001 is 180, both acute and chronic toxicity final effluent limitations have been assigned to Discharge Point 001. Since the Dm for Discharge Point 002 (i.e., Dm = 36) is less than 99, only chronic toxicity monitoring is specified for Discharge Point 002. No acute toxicity final effluent limitations have been assigned to Discharge Point 002 consistent with 40 CFR § 122.44(d)(1)(v), and because the chronic toxicity final effluent limitation is protective of both chronic and acute toxicity. The Ocean Plan establishes a daily maximum chronic toxicity objective of 1.0 TUB = 100/NOEC and a daily maximum acute toxicity objective of 0.3 TUa = 100/1-050. In 2010, USEPA published a guidance document titled National Pollutant Discharge Elimination System Test of Significant Toxicity Implementation Document (EPA 833-R-10-003, 2010), in which they recommend the following: "Permitting authorities should consider adding the Test of Significant Toxicity (TST) statistical approach to their implementation procedures for analyzing valid WET data for their current NPDES WET Program." The TST hypothesis testing ATTACHMENT F- FACT SHEET F-41 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS approach more reliably identifies toxicity—in relation to the chronic (equal to or greater than 0.25) and acute (equal to or greater than 0.20) mean responses of regulatory management decision—than the NOEC hypothesis-testing approach used in the Ocean Plan. The TST statistical approach is the improved approach for addressing statistical uncertainty when used in combination with USEPA's toxicity test methods and is implemented in federal permits issued by USEPA Region 9. Therefore, this Order/Permit includes final effluent limitations for both Discharge Point 001 (120"outfall) and Discharge Point 002 (78" outfall) using the TST hypothesis testing approach. This statistical approach is consistent with the Ocean Plan in that it provides maximum protection to the environment since it more reliably identifies acute and chronic toxicity than the NOEC hypothesis- testing approach (See Chapter III.F and Appendix I of the 2019 California Ocean Plan). The discharge is subject to determination of "Pass" or "Fail" from acute and/or chronic toxicity tests using the TST statistical t-test approach described in the National Pollutant Discharge Elimination System Test of Significant Toxicity Implementation Document (USEPA 833-R-10-003, 2010), Appendix A, Figure A- 1, Table A-1, and Appendix B, Table B-1. The TST's null hypothesis (Ho) for chronic toxicity is: Ho: Mean discharge In-stream Waste Concentration (IWC) response :50.75 x Mean control response. The TST's null hypothesis (Ho) for acute toxicity is: Ho: Mean discharge In-stream Waste Concentration (IWC) response :50.80 x Mean control response. A test result that rejects this null hypothesis is reported as "Pass." A test result that does not reject this null hypothesis is reported as "Fail." WQBEL Calculation for Chronic Toxicity (Discharge Points 001 and 002) The chronic toxicity WQBEL for Discharge Point 001 is expressed as a null hypothesis (Ho) and regulatory management decision (b value) of 0.75 for the chronic toxicity methods in Attachment E — Monitoring and Reporting Program. The chronic toxicity In-stream Waste Concentration (IWC) is 100/Dm = 100/180 = 0.556% for Discharge Point 001 (120" outfall) and IWC = 100/36 = 2.78% for Discharge Point 002 (78" outfall). The null hypothesis for chronic toxicity at Discharge Point 001 is: Ho: Mean response (0.556% effluent) <_ 0.75 mean response (Control) The null hypothesis for chronic toxicity at Discharge Point 002 is: Ho: Mean response (2.78% effluent) <_ 0.75 mean response (Control) WQBEL Calculation for Acute Toxicity (Discharge Point 001) ATTACHMENT F- FACT SHEET F-42 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS The acute toxicity WQBEL for Discharge Point 001 is expressed as a null hypothesis (Ho) and regulatory management decision (b value) of 0.80 for the acute toxicity methods in Attachment E — Monitoring and Reporting Program. The acute toxicity In-stream Waste Concentration (in % effluent) for Discharge Point 001 is 100/(0.1*Dm) = 100/(0.1*180) = 5.56%. The null hypothesis for acute toxicity at Discharge Point 001 is: Ho: Mean response (5.56% effluent) <_ 0.80 mean response (Control). Results obtained from evaluating statistically the IWC compared to the control shall be analyzed using the TST hypothesis testing approach in Attachment E — Monitoring and Reporting Program. Compliance with these acute and chronic toxicity WQBELs is demonstrated by rejecting the null hypothesis and reporting "Pass" or "P". The Maximum Daily Effluent Limitation (MDEL) for acute or chronic toxicity is exceeded and a violation will be flagged when WET test, analyzed using the TST statistical approach, results in "Fail". D. Final Effluent Limitation Considerations 1. Anti-Backsliding Requirements Sections 402(o) and 303(d)(4) of the CWA and federal regulations at 40 CFR § 122.44(I) prohibit backsliding in NPDES permits. These anti-backsliding provisions require effluent limitations in a reissued permit to be as stringent as those in the previous permit, with some exceptions where limitations may be relaxed. All effluent limitations and conditions in this Order/Permit are at least as stringent as those in the previous Order/Permit. This Order/Permit implements different bacteria indicators and water quality objectives based on Chapter II.B.1 of the 2019 Ocean Plan (i.e., State Water Board Water-Contact Objectives for Bacteria). The California Ocean Plan was amended in 2018 to revise the bacterial objectives for ocean waters used for water contact recreation, which includes removal of the previously established total coliform objectives and the revised enterococci objectives based on the EPA 2012 Recreational Criteria for marine waters. This Order/Permit has established bacteria effluent limitations at Discharge Point 002 (78" outfall) based on the amended objectives in the 2019 Ocean Plan. The new effluent limitations are expressed using different averaging periods than the previous limits and are therefore not directly comparable. 2. Antidegradation Policies Pursuant to 40 CFR 131.12, the state water quality standards must include an antidegradation policy consistent with the federal antidegradation policy. The State Water Board established California's antidegradation policy in State Water Board Resolution No. 68-16. This resolution incorporates the federal antidegradation policy, where the federal policy applies under federal law. Resolution No. 68-16 requires that existing water quality be maintained unless it is demonstrated that any degradation is consistent with the maximum benefit to ATTACHMENT F- FACT SHEET F-43 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS the people of the State, will not unreasonably affect current or possible beneficial uses, and will not result in water quality less than prescribed in applicable policies. A complete antidegradation analysis is required if the proposed activity results in a substantial increase in mass emissions of pollutants or if the activity results in significant impact to aquatic life. It is not necessary to do a complete antidegradation analysis if the reduction in water quality will be spatially localized or limited with respect to the waterbody. In such cases, a simple antidegradation analysis will suffice. The Santa Ana Water Board and USEPA believe that the simple antidegradation analysis presented herein is consistent with California and Federal antidegradation policies because effects from effluent discharges are spatially and temporally limited and not expected to have a significant impact on receiving water quality. This Order/Permit includes both narrative and numeric final effluent limitations, receiving water limitations, performance goals, and mass emission benchmarks to maintain the chemical, physical, and biological characteristics, and to protect the beneficial uses, of the receiving water. These requirements ensure that all water quality objectives are being met outside the zone of initial dilution, thereby maintaining the beneficial uses. The Ocean Plan allows for minimal degradation within the zone of initial dilution as long as the water quality objectives are maintained just outside the zone of initial dilution. The minimal degradation permitted by the Ocean Plan is consistent with the antidegradation policy because it maintains maximum benefit to the people of the State, it will not unreasonably affect the present and anticipated beneficial uses, and it will not result in water quality less than that prescribed in the policies. The final effluent limitations from the previous Order/Permit have been retained. Bacteria limits at Discharge Point 002 (78" outfall) were updated to implement new State water quality objectives for bacteria in the 2019 Ocean Plan. The new effluent limitations for fecal coliform and enterococcus are consistent with the State's antidegradation policy because the discharge is in compliance with new State Water Board water-contact objectives for bacteria in the Pacific Ocean. In addition, receiving water limitations for bacteria are included to further limit bacteria and to ensure that any increase in the bacteria levels due to cessation of disinfection at Discharge Point 001 (120" outfall) will be maintained below the applicable bacteria water quality standards. Full secondary treatment and these bacteria limitations will ensure that undisinfected effluent discharges will not adversely impact human health and receiving water quality for REC-1 beneficial uses. The performance goal and mass emission benchmarks are additional incentives for the Discharger to maintain the current treatment quality since they set final effluent targets for the Discharger to meet based on current performance. Most mass emission benchmarks in this Order/Permit are more stringent due to improved performance by full secondary treatment and a basis of lower flow rate (i.e., the average daily influent flow of 206 MGD projected for 2025); however, the ATTACHMENT F- FACT SHEET F-44 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS mass emission benchmarks for some constituents (e.g., selenium) have increased due to increased concentrations in the influent and/or more sensitive analysis methods. Since the mass emission benchmarks are based on actual performance and do not exceed the water quality objectives for the receiving water, the increase of any mass emission benchmarks is not expected to result in additional degradation. Compliance with all permit-specified concentration-based and mass emission- based limits, performance goals, mass emission benchmarks, and the secondary treatment requirements for final effluent discharges in the Order/Permit will result in the use of best practicable treatment or control of the discharge necessary to assure that a pollution or nuisance will not occur and that the highest water quality consistent with the maximum benefit to the people of the state will be maintained. Additionally, the secondary treatment facilities would support the Groundwater Replenishment System, reduce the effluent discharge volumes to the ocean, and reduce the need for emergency use of Discharge Point 002 (78" short outfall). Therefore, it is believed that these changes would represent socioeconomic and public benefits, and the Discharger meets the goals of the antidegradation policy. Based on these considerations, this Order/Permit is consistent with state and federal antidegradation requirements. 3. Stringency of Requirements for Individual Pollutants This Order contains both technology-based and water quality-based effluent limitations for individual pollutants. The technology-based effluent limitations consist of restrictions on biochemical oxygen demand (5-day), carbonaceous biochemical oxygen demand (5-day), total suspended solids, and pH which implement the minimum, applicable federal technology-based requirements for POTWs. Also, effluent limitations consisting of restrictions on oil and grease, settleable solids, and turbidity more stringent than federal technology-based limitations are necessary to implement State treatment standards in Ocean Plan Table 4. Water quality-based effluent limitations (WQBELs) have been derived to implement water quality objectives that protect beneficial uses. Both the beneficial uses and the water quality objectives have been approved pursuant to federal law and are the applicable federal water quality standards. The procedures for calculating the individual WQBELs are based on the Ocean Plan, which was approved by USEPA on February 14, 2006 and has since been further amended. All beneficial uses and water quality objectives contained in the Basin Plan were approved under state law and submitted to and approved by USEPA prior to May 30, 2000. Any water quality objectives and beneficial uses submitted to USEPA prior to May 30, 2000, but not approved by USEPA before that date, are nonetheless "applicable water quality standards for purposes of the CWX pursuant to 40 CFR § 131.21(c)(1). Discharge Point 001 WQBELs consisting of restrictions on total chlorine residual, acute toxicity, chronic toxicity, radioactivity, benzidine, hexachlorobenzene, ATTACHMENT F- FACT SHEET F-45 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS PCBs, TCDD equivalents, and toxaphene more stringent than federal technology- based limitations are necessary to meet State water quality standards in the Ocean Plan. Discharge Point 002 WQBELs consisting of restrictions on ammonia (as N), total chlorine residual, fecal coliform density, Enterococcus density, chronic toxicity, radioactivity, and TCDD equivalents more stringent than federal technology-based limitations are necessary to meet State water quality standards in the Ocean Plan. All effluent limitations are discussed in Attachment F-Fact Sheet. Collectively, the restrictions on individual pollutants in this Order/Permit are no more stringent than required to implement the requirements of the CWA. E.

Performance Goal Section III.F.1 , of the 2019 Ocean Plan allows the Santa Ana Water Board to establish more restrictive water quality objectives and effluent limitations than those set forth in the Ocean Plan as necessary for the protection of the beneficial uses of ocean waters. Pursuant to this provision, performance goals that are more stringent than those based on Ocean Plan objectives are prescribed in this Order/Permit. This approach is consistent with the antidegradation policy in that it requires the Discharger to maintain its treatment level and effluent quality, recognizing normal variations in treatment efficiency and sampling and analytical techniques. However, this approach does not address substantial changes in treatment plant operations that could significantly affect the quality of the treated effluent. While performance goals were previously placed in many State-issued NPDES permits for POTWs, they have been discontinued for inland surface water discharges. For inland surface waters, the California Toxics Rule (40 CFR § 131.38) has resulted in effluent limitations as stringent as many performance goals. However, the Ocean Plan allows for significant dilution, and the continued use of performance goals serves to maintain existing treatment levels and effluent quality and supports State and federal antidegradation policies. The performance goals are based upon the last 5-year actual performance of the OC San's treatment plants and are specified only as an indication of the treatment efficiency of the Facility. The performance goals are not considered enforceable effluent limitations or standards for the regulation of discharge from the treatment facility. They are intended to minimize pollutant loading (primarily for toxics), while maintaining the incentive for future voluntary improvement of water quality whenever feasible, without the imposition of more stringent limits based on improved performance. The Discharger shall maintain existing treatment levels and the effluent quality at or below the performance goal concentrations. Any two consecutive exceedances of the performance goals shall trigger an investigation into the cause of the exceedance. If the exceedance persists in three successive monitoring periods, the Discharger shall submit a written report to the Santa Ana Water Board and USEPA on the nature of the exceedance and the results of the investigation including the cause of the exceedance. The Santa Ana Water Board and USEPA recognize that OC San is going through upgrades of treatment plant operations including the GWRS final expansion and ATTACHMENT F- FACT SHEET F-50 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS participating in collaborative studies and activities with regional partnerships. This Order/Permit may be reopened to modify any of the performance goals if the Discharger requests and has demonstrated that the change is warranted, including results of completion of the GWRS final expansion. Procedures for the Determination of Performance Goals 1. For constituents that have been routinely detected in the effluent (at least 20 percent detectable data), performance goals are based on the one-sided, upper 95 percent confidence bound for the 95t" percentile of the effluent performance data (UCB95/95) from May 2015 through December 2019 using the RPA protocol contained in the 2019 Ocean Plan. Effluent data are assumed log normally distributed. Performance goals are calculated according to the equation CPS _ Co+Dm(Co-Cs) and setting Co = UCB95/95. a. If the maximum detected effluent concentration (MEC) is greater than the calculated performance goal (CPc), then the calculated performance goal (CPc) is used as the performance goal; or b. If the MEC is less than the calculated performance goal (CPc), then the MEC is used as the performance goal. c. If the performance goal determined in part a or b above is greater than the Water Quality Objective (WQO) in the 2019 Ocean Plan after considering dilution, then the WQO is used as the performance goal. For example, the performance goals for arsenic and chloroform at Discharge Point 001 (120" outfall) are calculated as follows: Arsenic Co = UCB95/95 = 3.02 pg/L ; Dm= 180; Cs = background seawater concentration = 3 pg/L; MEC = 6.91 pg/L; CPc = Performance Goal = (3.02 pg/L) + 180*(3.02 fag/L - 3 fag/L) = 6.62 fag/L. Since the MEC of 6.91 fag/L is greater than the calculated PG of 6.62 fag/L, the prescribed performance goal for arsenic is 6.62 fag/L. Chloroform Co = UCB95/95 = 3.285 fag/L ; Dm= 180; Cs = background seawater concentration = 0 fag/L; MEC = 16.6 fag/L; CPc = Performance Goal = (3.285 fag/L) + 180*(3.285 fag/L - 0 fag/L) = 594.6 fag/L. Since the MEC of 16.6 fag/L is less than the calculated PG of 594.6 fag/L, the prescribed performance goal for chloroform is 16.6 pg/L. 2. For constituents where monitoring data have consistently shown nondetectable levels (less than 20 percent detectable data), performance goals are set at the multiplying factor of 2.13 times the Minimum Levels (ML) used for analysis, which is based on statistical procedures outlined in USEPA manual, the Technical Support Document for Water Quality-Based Toxics Control (TSD, 1991). These performance goals are estimated assuming a coefficient of variation of 0.6 and the ATTACHMENT F- FACT SHEET F-51 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS 95 percent confidence interval of the 95t" percentile based on an assumed lognormal distribution of daily efficient values (see Table 5-2 of USEPA's TSD) a. If the MEC is greater than the calculated performance goal based on ML (i.e., 2.13*ML), then the calculated performance goal (i.e., 2.13*ML) is used as the performance goal; or d. If the MEC is less than the calculated performance goal based on ML (i.e., 2.13*ML), then the MEC is used as the performance goal. e. If the performance goal determined in part a or b above is greater than the Water Quality Objective (WQO) in the 2019 Ocean Plan after considering dilution, then the WQO is used as the performance goal. For example, the performance goals for halomethanes and heptachlor at Discharge Point 001 (120" outfall) are calculated as follows: Halomethanes (5 detected out of 54 samples) MEC = 1.37 pg/L; ML = 0.2 pg/L; CPS = Performance Goal = 2.13*0.2 = 0.43 pg/L. Since the MEC of 1.37 fag/L is greater than the calculated PG of 0.43 fag/L, the prescribed performance goal for halomethanes is 0.43 pg/L Heptachlor (all nondetected) MEC = NA (all ND); ML = 0.01 pg/L; CPS = Performance Goal = 2.13*0.01 = 0.012 fag/L. Co = WQO = 0.00005 pg/L; Dm = 180; Cs = background seawater concentration = 0 fag/L; CPc = Performance Goal = (0.00005 fag/L) + 180*(0.00005 fag/L - 0 fag/L) _ 0.009 pg/L. Since the performance goal based on ML of 0.012 fag/L is greater than the calculated WQO-based performance goal of 0.009 pg/L, so the prescribed performance goal for heptachlor is 0.009 fag/L. 3. For constituents with effluent limitations, if the performance goal derived from the steps, above, exceeds respective effluent limitation, then a performance goal is not prescribed for that constituent. B. Mass Emission Benchmarks To address the uncertainty due to potential increases in toxic pollutant loadings from the discharge to the marine environment during the five-year Order/Permit term, and to establish a framework for evaluating the need for an antidegradation analysis to determine compliance with State and federal antidegradation requirements at the time of Order/Permit reissuance, 12-month average mass emission benchmarks have been established for effluent discharged through Discharge Point 001 (120" outfall). These mass emission benchmarks are not enforceable water quality-based effluent limitations. They may be re-evaluated and revised during the five-year Order/Permit term.

The following equation was used for the calculation of the Mass Emission Benchmarks: Mass Emission Benchmark (MT/yr) = (CPG pg/L) x (Q gal/day) x (3.785 L/gal) x (365 days/yr) x (1 MT/1012 fag) where, CPG: Final performance goal calculated from Section V.A of the fact sheet (fag/L) Q: Annual average influent flow projected for 2025 = 206X106 gal/day Most mass emission benchmarks in this Order/Permit are more stringent due to improved performance by completion of full secondary treatment facilities, the use of more sensitive analytical method with lower minimum levels, implementation of an extensive source control pretreatment program, and decreased discharge flowrate (i.e., the projected average daily influent flow reduced from 274 MGD to 206 MGD). VI. RATIONALE FOR RECEIVING WATER LIMITATIONS A. Surface Water The Ocean Plan and Basin Plan contain numeric and narrative water quality standards applicable to surface waters of California. Water quality objectives include a policy to maintain the high-quality waters pursuant to federal regulations (40 CFR § 131.12) and State Water Board Resolution No. 68-16. Receiving water limitations in the Order/Permit are based on the water quality objectives contained in the Ocean Plan chapters II.B, II.C, II.D, II.E, and II.F. The Ocean Plan was amended in 2018 to revise the bacterial water quality objectives for ocean waters used for water contact recreation, which includes removal of the previously established total coliform objectives and the revised enterococci objectives based on the EPA 2012 Recreational Criteria for marine waters. The previously established fecal coliform objective has been retained as recent epidemiological studies conducted at southern California beaches showed that fecal coliform may be a better indicator of gastrointestinal illness than enterococci during certain types of exposures and environmental conditions. This Order/Permit has established receiving water limitations for bacteria based on these amended objectives in the 2019 Ocean Plan. Bacteria receiving water limitations are necessary to protect human health and the water contact recreation uses of the receiving water. The Santa Ana Water Board and USEPA has determined that bacterial indicator standards for water contact recreation are applied throughout the water column of the Nearshore Zone (i.e., designated REC-1). Based on Chapter ll.B.1 of the Ocean Plan, bacterial indicator standards shall also be maintained throughout the water ATTACHMENT F- FACT SHEET F-53 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS column in the Offshore Zone used for water contact sports, as determined by the Santa Ana Water Board and/or USEPA (i.e., waters designated as REC-1), to assure that the discharge does not pose a threat to water contact recreation. Receiving water limitations for enterococcus density in ocean waters beyond the outer limit of the State of California territorial marine waters are based on CWA section 304(a) water quality criteria (i.e., Recreational Water Quality Criteria). These criteria must be achieved beyond the zone of initial dilution in areas where primary contact recreation, as defined in USEPA guidance, occurs. USEPA describes the "primary contact recreation" use as protective when the potential for ingestion of, or immersion in, water is likely. Activities usually include swimming, water-skiing, skin- diving, surfing, and other activities likely to result in immersion (Water Quality Standards Handbook, EPA-823-B-94-005a, 1994, p. 2-2). The nature and extent of primary contact recreational use in federal waters is recorded and reported during water quality monitoring conducted under the receiving water core monitoring program. B. Groundwater— Not Applicable VII. RATIONALE FOR PROVISIONS A. Standard Provisions Standard Provisions, which apply to all NPDES permits in accordance with 40 CFR § 122.41, and additional conditions applicable to specified categories of permits in accordance with 40 CFR § 122.42, are provided in Attachment D of this Order/Permit. 40 CFR § 122.41(a)(1) and (b) through (n) establish conditions that apply to all State- issued NPDES permits. The Order/Permit also incorporates federal conditions that address enforcement authority specified in 40 CFR § 122.41(a)(2) and (3). These conditions must be incorporated into the permits either expressly or by reference. If incorporated by reference, a specific citation to the regulations must be included in the Order/Permit. 40 CFR § 123.25(a)(12) allows the state to omit or modify conditions to impose more stringent requirements. In accordance with 40 CFR § 123.25, this Order/Permit omits federal conditions that address enforcement authority specified in 40 CFR § 122.41(j)(5) and (k)(2) because the enforcement authority under the Water Code is more stringent. In lieu of these conditions, this Order/Permit incorporates by reference Water Code section 13387(e). B. Special Provisions 1. Reopener Provisions The reopener provisions are based on 40 CFR 122.44(c) and 40 CFR § 123.25. The Santa Ana Water Board and USEPA may reopen the Order/Permit to modify conditions and requirements for cause. Causes for modification can include, but are not limited to, the promulgation of new regulations, modification in sludge use or disposal practices, or adoption of new regulations by the State Water Board, ATTACHMENT F- FACT SHEET F-54 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES N0. CA0110604 COLLECTION SYSTEM & OUTFALLS Santa Ana Water Board, or USEPA including revisions to the Ocean Plan and Basin Plan. 2. Southern California Bight Monitoring Exchange The MRP (Attachment E) may be modified by the Santa Ana Water Board and USEPA to enable the Discharger to participate in comprehensive regional monitoring activities conducted in the Southern California Bight during the term of this permit. The intent of regional monitoring activities is to maximize the efforts of all monitoring partners using a cost-effective monitoring design and to best utilize the pooled scientific resources of the region. During these coordinated monitoring efforts, the Discharger's sampling and analytical effort may be reallocated to provide a regional assessment of the impact of wastewater discharges to the Southern California Bight; however, certain core elements (i.e., monthly water quality monitoring, quarterly REC-1 water quality monitoring, quarterly benthic monitoring, semi-annual trawl fish monitoring, and weekly Orange County Regional Shoreline REC-1 cooperative monitoring) shall remain unchanged. Anticipated modifications to the monitoring program will be coordinated so as to provide a comprehensive picture of the ecological and statistical significance of monitoring results and to determine cumulative impacts of various pollutant sources. If predictable relationships among the biological, water quality and effluent monitoring variables can be demonstrated, it may be appropriate to decrease the Discharger's monitoring effort. Conversely, the monitoring program may be intensified if it appears that the objectives cannot be achieved through the Discharger's existing monitoring program. These changes will improve the overall effectiveness of monitoring in the Southern California Bight. Minor changes may be made without further public notice. 3. Special Studies, Technical Reports, and Additional Monitoring Requirements a. Toxicity Reduction Requirements This Order/Permit requires the Discharger to develop procedures to conduct Toxicity Identification and Reduction Evaluations. This provision is based on Chapter III.C.10 of the Ocean Plan. If the discharge consistently exceeds an effluent limitation for toxicity as specified in this Order/Permit, the Discharger shall conduct a Toxicity Reduction Evaluation (TRE) as detailed in section VII.C.3.a of the Order/Permit. The THE will help the Discharger identify the possible source(s) of toxicity. Once the source(s) of toxicity is identified, the Discharger shall take all reasonable steps to reduce toxicity to the required level. b. Dilution Model Update This Permit/Order requires the Discharger to complete an updated dilution analysis for all outfalls as part of its permit application for the next permit reissuance. The Discharger shall update its dilution modeling that is reflective of the future operations upon completion of the GWRS final expansion ATTACHMENT F- FACT SHEET F-55 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS project, which includes, but not limited to the increase in RO concentrate and density and lower discharge flow rate. The updated dilution analysis must continue to use near-field modeling to consider how the effluent plumes behave in the zone of initial dilution (ZID) and demonstrate the impacts of final GWRS expansion to dilution under a "reasonable worst-case scenario" (e.g., critical stratification condition). c. Ocean Outfall Condition Assessment and Scoping Study As the 120-inch outfall approaches the end of life in 2021 , the Discharger is undertaking a condition assessment of the 120-inch ocean outfall (referred to as PS18-09). The project includes removal of accumulated biofouling (i.e., barnacle collar) surrounding the 504 diffuser ports, removal/replacement of manhole covers, the full-length underwater interior inspection of the 120-inch outfall pipe, 3-D scanning and modeling, and analysis of low flow impacts on the diffuser functionality. The first field activity for the 120" inch outfall assessment project (i.e., removal of the barnacles from the outfall ports) was started on July 20, 2020 after the receipt of the Army Corp. of Engineers' permit. OC San also plans to conduct a similar study for Discharge Point 002 (78" outfall) using lessons learned from this 120" outfall condition assessment and scoping study. Upon completion of each outfall condition assessment project, a summary report of the field work findings, including videographic and/or photographic record of the interior of the outfall, 3-D mapping, and any environmental impacts caused during the field works shall be submitted to the Santa Ana Water Board and USEPA. In addition, a separate analysis report of the impacts of low flows on diffuser hydraulics and plugging shall be provided. 4. Best Management Practices and Pollution Prevention a. Pollution Minimization Program This provision is based on the requirements of Chapter III.C.9 of the 2019 Ocean Plan. The goal of the Pollutant Minimization Program is to reduce all potential sources of a pollutant through pollutant minimization strategies, including pollution prevention measures, in order to maintain the effluent concentration at or below the effluent limitation. b. Storm Water Management Plan This Order/Permit requires the Discharger to update its Storm Water Management Plan to implement the 2015 trash amendments of the Ocean Plan. 5. Construction, Operation, and Maintenance Specifications This provision is based on the requirements of 40 CFR §122.41(e) and the previous Order/Permit. a. Roster of Personnel ATTACHMENT F- FACT SHEET F-56 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS The Discharger shall update and report annually a roster of personnel who supervises and operates the wastewater treatment plants. b. Operation and Maintenance Manual This Order/Permit requires the Discharger to update an Operation and Maintenance Manual prior to start of operations and specifies its periodic updates. c. Spill Preventive and Contingency Plan (SPCP) Since spills or overflows are a common event at the POTW, this Order/Permit requires the Discharger to review and update, if necessary, its SPCP whenever there is a change which materially affects the potential for spills or after each incident. The Discharger shall ensure that the up-to-date SPCP is readily available to the sewage system personnel at all times and that the sewage personnel are familiar with it. 6. Special Provisions for Publicly-Owned Treatment Works (POTWs) a. Biosolids To implement CWA section 405(d), on February 19, 1993, USEPA promulgated 40 CFR § 503 to regulate the use and disposal of municipal sewage sludge. This regulation was amended on September 3, 1999. The regulation requires that producers of sewage sludge meet certain reporting, handling, and disposal requirements. It is the responsibility of the Discharger to comply with said regulations that are enforceable by USEPA, because California has not been delegated the authority to implement this biosolid program. b. Pretreatment This Order/Permit contains pretreatment requirements consistent with applicable effluent limitations, national standards of performance, and toxic and performance effluent standards established pursuant to Sections 208(b), 301 , 302, 303(d), 304, 306, 307, 403, 404, 405, and 501 of the CWA, and amendments thereto. This permit contains requirements for the implementation of an effective pretreatment program pursuant to Section 307 of the CWA; 40 CFR § 35 and 403; and/or Section 2233, Title 23, California Code of Regulations. c. Collection System The State Water Board issued General Waste Discharge Requirements for Sanitary Sewer Systems, Water Quality Order 2006-0003-DWQ (General Order) on May 2, 2006. The State Water Board amended the Monitoring and Reporting Program for the General Order through Order WQ 2013-0058- EXEC on August 6, 2013. The General Order requires public agencies that own or operate sanitary sewer systems with sewer lines one mile of pipe or greater to enroll for coverage and comply with the General Order. The General Order requires agencies to develop sanitary sewer management ATTACHMENT F- FACT SHEET F-57 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS plans and report all sanitary sewer overflows, among other requirements and prohibitions. The General Order contains requirements for operation and maintenance of collection systems and for reporting and mitigating sanitary sewer overflows that are more extensive, and therefore, more stringent than the requirements under federal standard provisions. The Discharger and public agencies that are discharging wastewater into the facility's collection system were required to obtain enrollment for regulation under the General Order by December 1, 2006. d. Resource Recovery from Anaerobically Digestible Material. Some POTWs choose to accept organic material such as food waste, fats, oils, and grease into their anaerobic digesters for co-digestion to increase production of methane and other biogases for energy production and to prevent such materials from being discharged into the collection system, which could cause sanitary sewer overflows. The California Department of Resources Recycling and Recovery has proposed an exemption from requiring Process Facility/Transfer Station permits where this activity is regulated under waste discharge requirements or NPDES permits. The proposed exemption is restricted to anaerobically digestible material that has been prescreened, slurried, and processed/conveyed in a closed system to be co-digested with regular POTW sludge. The proposed exemption requires that a POTW develop Standard Operating Procedures for the proper handling, processing, tracking, and management of the anaerobically digestible material before it is received by the POTW. Standard Operating Procedures are required for POTWs that accept hauled food waste, fats, oil, and grease for injection into anaerobic digesters. The development and implementation of Standard Operating Procedures for management of these materials is intended to allow the California Department of Resources Recycling and Recovery to exempt this activity from separate and redundant permitting programs. If the POTW does not accept food waste, fats, oil, or grease for resource recovery purposes, it is not required to develop and implement Standard Operating Procedures. e. Ensuring Adequate Treatment Capacity The Discharger shall submit a written report to the Santa Ana Water Board and USEPA within 90 days after the monthly average influent flow rate equals or exceeds 75 percent of the secondary design capacity of the POTW to prevent the waste flow exceeding the capacity of the POTW. f. Asset Management This Order/Permit requires the Discharger to develop an asset management program to cover the POTW. 7. Other Special Provisions ATTACHMENT F- FACT SHEET F-58 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS a. Monitoring Data Accessibility This Order/Permit requires the Discharge to make monitoring data accessible to the public via the internet. 8. Compliance Schedules — Not Applicable Vill. RATIONALE FOR MONITORING AND REPORTING REQUIREMENTS CWA section 308 and 40 CFR § 122.41(h), 0)-(1), 122.44(i), and 122.48 require that all NPDES permits specify monitoring and reporting requirements. California Water Code sections 13267 and 13383 also authorize the Santa Ana Water Board to establish monitoring, inspection, entry, reporting, and recordkeeping requirements. The Monitoring and Reporting Program (MRP), Attachment E of this Order establishes monitoring, reporting, and recordkeeping requirements that implement federal and state requirements. The following provides the rationale for the monitoring and reporting requirements contained in the MRP for this facility. The MRP is guided, in part, by the principals, framework, and recommended design for discharge and receiving water monitoring presented in the Ocean Plan and Model Monitoring Program for Large Ocean Dischargers in Southern California (SCCWRP Tech. Rep. #357. Southern California Coastal Water Research Project, Westminster, CA. 2002). The conceptual framework for the MRP has three components that comprise a range of spatial and temporal scales: (1) core monitoring, (2) regional monitoring, and (3) strategic process studies. Core Monitoring. Core monitoring is local in nature and focuses on monitoring trends in quality and effects of the point source discharge. This includes effluent monitoring, as well as many aspects of receiving water monitoring. Regional Monitoring. Regional monitoring is focused on questions best answered by a region-wide approach that incorporates coordinated survey design and sampling techniques. Key components of regional monitoring include elements to address pollutant mass emission estimates, public health concerns, monitoring trends in natural resources, assessment of regional impacts from all contaminant sources, and beneficial use protection. The final designs of regional monitoring programs are developed by means of steering and technical committees comprised of participating agencies and organizations. For each component of regional monitoring, the MRP specifies the required degree and nature of participation by the Discharger, based upon its past participation in regional monitoring programs. Strategic Process Studies. Strategic process studies are focused on refined questions regarding specific effects or development of monitoring techniques and are anticipated to be of short duration and/or small scale, although multi-year studies also may be needed. Questions regarding discharge or receiving water quality, discharge impacts, ocean processes in the area of the discharge, or development of techniques for monitoring the same, arising out of the results of core or regional monitoring, may be pursued through strategic process studies. These studies are by nature ad hoc and, typically, cannot be typically anticipated in advance of the five-year permit cycle. ATTACHMENT F- FACT SHEET F-59 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS A. Influent Monitoring Influent monitoring is required to determine compliance with effluent limitations and permit conditions, assess the performance of treatment facilities and evaluate the effectiveness of pretreatment and nonindustrial source control programs. Influent monitoring in this Order/Permit follows the influent monitoring requirements in the previous Order/Permit with minor changes. The sample type and monitoring frequencies for halomethanes and 1,4-Dichlorobenzene were changed to grab and 1/quarter, respectively, to be consistent with other volatiles constituents. The monitoring frequency for ammonia nitrogen has been changed to weekly for proper self-monitoring as scheduled in Table E-16. The monitoring requirements for tributyltin and TCDD equivalents have been included. B. Effluent Monitoring Effluent monitoring is required to determine compliance with effluent limitations and permit conditions, and to identify operational problems and improve treatment facility performance. Effluent monitoring also provides information on discharge characteristics and flows for use in interpreting receiving water monitoring data. Effluent monitoring requirements also addresses the three management questions for effluent monitoring in Model Monitoring Program for Large Ocean Discharges in Southern California (SCCWRP, 2002; Model Monitoring Program): Is the effluent concentration of selected constituents below levels that will protect human health and aquatic life? What is the mass of selected constituents that are discharged annually? Is the effluent concentration or mass changing over time? Noteworthy changes for this Order/Permit include removal of total coliform monitoring at Discharge Point 002 (78" outfall) due to new bacteria water quality objectives in the 2019 Ocean Plan, more frequent monitoring for nutrient parameters, addition of annual monitoring for total nitrogen and quarterly monitoring for tributyltin, changes in monitoring frequencies for ammonia nitrogen for proper self-monitoring as scheduled in Table E-16, and changes in the sample type and/or monitoring frequencies for halomethanes and 1,4-Dichlorobenzene to be consistent with other volatile constituents. In addition, effluent monitoring stations have been defined separately, for the effluent discharged to Discharge Point 001 during normal operations as EFF-001 and to Discharge Point 002 during planned essential maintenance or capital improvement projects as EFF-002, in order to determine compliance with each permit limitation and requirement. C. Whole Effluent Toxicity Testing Requirements The rationale for WET has been discussed extensively in Section IV.C.5. of this Fact Sheet. Noteworthy WET changes for this Order/Permit include WET testing for Discharge Point 002 (78" outfall) using the TST hypothesis testing approach instead of ATTACHMENT F- FACT SHEET F-60 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS NOEC statistical approach. This TST statistical approach is consistent with the Ocean Plan in that it provides maximum protection to the environment since it more reliably identifies chronic toxicity than the previous NOEC hypothesis-testing approach. D. Receiving Water Core Monitoring To evaluate potential environmental and human health impacts from its discharge of final effluent into the Pacific Ocean, the Discharger conducts extensive water quality, sediment quality, fish and invertebrate community, and fish health monitoring off the coastal cities of Newport Beach and Huntington Beach, California. 1. Water Quality Monitoring Offshore water quality monitoring data are used to determine compliance with receiving water limitations and Ocean Plan objectives for physical and chemical parameters, and assist in the interpretation of biological data. Water quality data collected provide the information necessary to demonstrate compliance with the water quality standards. Water quality monitoring requirements also addresses the two management questions for water quality monitoring in the Model Monitoring Program: Are water column physical and chemical parameters within ranges that ensure protection of the ecosystem? What is the fate of the discharge plume? Monthly water quality monitoring will be carried out over a large grid of 28 stations centered on Discharge Point 001 (120" outfall). The station grid covers from the coastline of Huntington Beach to Newport Beach. Noteworthy changes for this Order/Permit include the addition of monthly monitoring for nitrate nitrogen to further investigate nutrients driving ocean acidification and the relationship between nutrients discharged through Discharge Point 001 (120" outfall) and harmful algal blooms. 2. REC-1 Water Quality Monitoring (Offshore Zone) This REC-1 water quality monitoring is designed to determine if Ocean Plan water quality objectives for physical and chemical parameters and bacteria are being met. Data collected at these REC-1 monitoring stations provide the means to determine whether water quality standard and bacteriological objectives for water contact are being met. REC-1 monitoring requirements also addresses the two management questions for REC-1 monitoring in the Model Monitoring Program: Does sewage effluent reach water contact zones? Are densities of bacteria in water contact zones below levels that will ensure public safety? Quarterly (5-days/30-day period), REC-1 monitoring will be carried out over a picket-line of the 8 stations centered inshore of Discharge Point 001 (120" ATTACHMENT F- FACT SHEET F-61 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS outfall), in State waters. The south-to-north station alignment is adjacent to the coastline of Huntington Beach and Newport Beach. 3. Sediment Monitoring The purpose of sediment monitoring is to map the area of impact and detect spatial and temporal trends in sediment pollutants and benthic infauna in the area of the discharge, and to assess compliance with State water quality standards and federal criteria. The data collected are used for regular assessment of trends in sediment contamination and biological response along a fixed grid of sites within the influence of the discharge. Sediment monitoring requirements also addresses the two management questions for sediment monitoring in the Model Monitoring Program: Are sediments in the vicinity of the discharge impaired? If so, what is the spatial extent of impairment? Are sediment conditions changing over time? The previous benthic sampling grid consisted of 29 semi-annual monitoring stations and 39 annual monitoring stations. The previous semi-annual station array is based on a sediment mapping study conducted by the Southern California Coastal Water Research Project (SCCWRP) from 2009 to 2012. This study recommended the design to best capture changes in sediment quality resulting from the effluent discharge. The investigation into changes in benthic community health as a result of the District's effluent disinfection with chlorine bleach (Changes in Biological Communities near the OCSD Outfall, OCSD Marine Monitoring, 2013) revealed that impacts to benthic communities were localized to stations at and near (< 1 km) the 120" outfall diffuser. Impacts were seen at Stations 0, 1, 3, 4, 9, 84, 85, 86, 87, and ZB. All other stations were unaffected even though the degree of impact was severe at near outfall stations. Based on these results and over three decades of monitoring data, a more effective and efficient sediment monitoring station design has been constructed in this Order/Permit as below: a. Quarterly sampling for sediment chemistry and benthic infauna at 11 stations immediately surrounding the 120" outfall diffuser along the 60-meter contour line, including 3 stations within the ZID boundaries. (Note that these quarterly monitoring stations were the first and the most severely impacted stations by effluent chlorination.) b. Annual whole sediment toxicity sampling at the 11 quarterly monitoring stations. c. Annual (summer) sampling for sediment chemistry and benthic infauna at 11 stations located near the outfall and extending northward and southward along the 60-meter contour line. ATTACHMENT F- FACT SHEET F-62 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS d. Once per 5 year (1/5-year) sampling for sediment chemistry and benthic infauna at an additional 35 stations centered on Discharge Point 001 (120" outfall) from Huntington Beach to Newport Beach coastlines. Stations 68, 69, 70,71 , 72, 79, 80, 81, and 82 were eliminated as they are redundant to the station design. Downcoast Station C2 and farfield upcoast Station C were also removed as the sediment quality and biological community at these stations have been consistently different from those of other 60 m stations including control station, considering outliers. Therefore, total number of stations is reduced from 68 stations to 57 stations. The reduction in taxonomic and sediment geochemical analyses would enable the Discharger to redirect its efforts toward SPS and special studies to evaluate potential environmental impacts related to increased wastewater reclamation efforts and investigate CEC identification and characterization in effluent and sediments and toward the regional monitoring programs including Bight 18. With the new sediment monitoring design, the number of stations sampled annually in summer is reduced from 68 to 22, which can reduce the turn-around time for summer data from approximately 9 to 12 months to 3 months, especially for the 11 quarterly stations in all seasons. This will provide a rapid assessment of sediment conditions and a more rapid response to changes in sediment quality and/or benthic infauna community within the monitoring area. Noteworthy changes for this Order/Permit also include the change in sampling frequency for 35 monitoring stations that previously sampled annually to one-off (i.e., once per 5 years) since these stations are either not directly or not significantly impacted by the effluent discharge. Three (3) stations (i.e., Stations 10, 13, and 37) at the 60-m contour line remains as annual monitoring stations. Sampling these 1/5-year monitoring stations allows long-term trend analysis to continue in these areas where change occurs much more slowly in response to changes in effluent quality than at the outfall diffuser. 4. Demersal Fish and Epibenthic Macroinvertebrate Monitoring The purpose of demersal fish and epibenthic macroinvertebrate monitoring is to detect spatial and temporal trends in demersal fish and epibenthic community structure, demersal fish liver tissue chemistry and liver histopathology, and sport fish muscle tissue chemistry in the area of the discharge, and to assess compliance with State water quality standards and federal criteria. The demersal fish and epibenthic macroinvertebrate monitoring data collected are used for regular assessment of temporal trends in community structure along an array of sites within the influence of the discharge. The sport fish monitoring data collected are used to provide information necessary for the management of local seafood consumption advisories. Demersal fish and epibenthic invertebrate monitoring requirements also address the four management questions for fish and epibenthic invertebrate monitoring and seafood safety monitoring in the Model Monitoring Program: ATTACHMENT F- FACT SHEET F-63 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS Is the health of fish populations and communities impaired? Are fish populations and communities changing over time? Is fish tissue contamination changing over time? Are seafood tissue concentrations below levels that will ensure public safety? Annual demersal fish and epibenthic community monitoring continues to be carried out over a grid of 14 stations upcoast of Discharge Point 001 (120" outfall); of these 14 stations, the 6 stations at the outfall depth (60 meters) are monitored semi-annually. The monitoring area covers approximately 27 square kilometers adjacent to the coastline of Huntington Beach and Newport Beach. Annual demersal fish tissue chemistry monitoring is carried out over two stations upcoast of Discharge Point 001 at the outfall depth. Annual sport fish muscle tissue chemistry monitoring is also conducted in summer at two zones. Noteworthy changes for this Order/Permit are listed below: a. Target fish species. For demersal fish and epibenthic community monitoring, the previous Order/Permit required at least 10 individuals of each target species (i.e., Hornyhead Turbot and English Sole) per station. This Order/Permit allows the Discharger to collect 20 individuals total of flat fish (e.g., Pacific Sanddab, Hornyhead Turbot and English Sole) per station. For sport fish monitoring, the Discharger can collect 10 individuals total of rockfish (e.g., Vermilion Rockfish, Copper Rockfish, and California Scorpionfish) at each rig fish monitoring zone. Kelp bass and Sandbass are removed from the target species list in this Order/Permit because none of these fishes was caught by the Discharger at any of the three rig fishing zones in the past three monitoring periods (2014 — 2016). b. Demersal fish tissue chemistry monitoring - Target tissue. The previous Order/Permit required sampling and analysis of both fish liver and muscle tissues in Hornyhead Turbot and English Sole for the assessment of predator wildlife risk by consuming these two target fish species. Noteworthy change in demersal fish tissue chemistry monitoring for this Order/Permit includes removal of muscle tissue and analysis of contaminants in fish liver tissue only. The concentration of contaminants in demersal fish muscle tissue were relatively negligible for two permit cycles compared with liver tissues, given that liver tissue has higher lipid content than muscle tissue and therefore can bioaccumulate higher concentrations of lipid-soluble contaminants such as PCBs and DDT. It stands to reason that when this demersal fish is consumed whole by a fish predator, it is likely that the predator will acquire considerably higher contaminant loads from liver tissue as compared to muscle tissue, rendering the muscle tissue analysis dispensable. c. Chemical analysis changes — Composite sampling. To monitor bioaccumulation of organic contaminants (i.e., PCBs, DDT, and Chlordane) and metals (i.e., Arsenic, Selenium, and Mercury) in either demersal fish liver tissue or sport fish muscle tissue, composite samples of target fish will be ATTACHMENT F- FACT SHEET F-64 ORANGE COUNTY SANITATION DISTRICT ORDER NO. R8-2021-0010 RECLAMATION PLANT NO. 1, TREATMENT PLANT NO. 2, NPDES NO. CA0110604 COLLECTION SYSTEM & OUTFALLS analyzed instead of individual sample analysis. This composite tissue analysis can minimize the variation between contaminant measurements, increase the ability to detect target compounds that are present in low concentrations, and improve the representativeness of the contaminant measurements at each sampling site, which is also consistent with fish tissue analysis protocols of other POTW ocean monitoring programs within the Southern California Bight. d. Monitoring frequency of demersal fish liver histopathology. Liver histopathology will be conducted on an annual basis instead of once every permit cycle to facilitate rapid detection of potential adverse effects on fish health by the anticipated changes in effluent quality and characteristics with GWRS final expansion (e.g., increased RO concentrate flow). Fish liver histopathology was used in the investigation of effluent chlorination effects and was found to be a useful biomarker of impact and the only significant effect on fish health. e. Sport fish monitoring - Farfield reference zone. The Discharger was not able to catch the number of fish samples required by the previous Order/Permit at the farfield reference zone (Zone 2) in two consecutive years (2014 — 2015) after the issuance of the previous 2012 Order/Permit. After consulting with scientists from the California Department of Fish and Wildlife, the reference zone was relocated to an area near the Huntington Beach oil rigs (Zone 3) as this site only met the species and number of fish requirements among several candidate sites. In this Order/Permit, Zone 2 was replaced with Zone 3 as a farfield reference zone. E. Receiving Water Regional Monitoring Discharger participation in regional monitoring programs continues to be a required condition of the Order/Permit. Regional monitoring programs which must be conducted under the Order/Permit include: Southern California Bight Regional Monitoring Program, Southern California Bight Regional Water Quality Program, Central Regional Kelp Survey, Orange County Regional Shoreline REC-1 Cooperative Monitoring Program, and Ocean Acidification and Hypoxia (OAH) Mooring. The Discharger currently participates in all five programs. For the regional monitoring program, collaboration with other water sectors (e.g., water supply, wastewater, groundwater, and stormwater) is encouraged to evaluate implementation of integrated water resource projects that helps achieve sustainable integrated water resources management. Noteworthy changes for the Southern California Bight Regional Water Quality Program under this Order/Permit include the addition of four field sampling surveys per year, removal of stations transects 2021, 2181, 2221, and 2349 for more equal spacing of transects, and creation of transect lines 1701, 1801 , and 2041 to extend sampling downcoast to Dana Point.

The number of Orange County Regional Shoreline REC-1 Cooperative Monitoring Program stations has been changed from 38 to 36 due to removal of two Stations (i.e., OSB02 and ELMORO) at the request of the Orange County Health Care Agency. F. Strategic Process Studies Discharger investigations conducted through strategic process studies continues to be a required condition of the Order/Permit. Strategic process studies which must be conducted under the Order/Permit include: ROMS-BEC Ocean Outfall Modeling, Microplastics Characterization, Contaminants of Emerging Concern Monitoring, Sediment Linear Alkylbenzenes, and Meiofauna Baseline. These studies have been approved by the Santa Ana Water Board and USEPA during the term of the 2012 Order/Permit but not yet completed by the Discharger. Additional studies will be proposed over the next permit cycle to ascertain if GWRS final expansion, which will result in lower outfall flows and higher concentration of the final effluent due to RO reject flow, will result in deleterious environmental impacts. G. Other Monitoring Requirements 1. Contaminants of Emerging Concern (CEC) Monitoring Study The Discharger shall continue to investigate CECs identification and characterization in the final effluent, listed in Table E-15 of the MRP (Attachment E). The Discharger has annually screened for 15 pharmaceuticals and personal care products (PPCPs), 7 hormones, 7 industrial endocrine disrupting compounds (IEDCs), and 9 flame retardants in the final effluent in the previous permit. In addition, this Order/Permit requires the Discharger to conduct monitoring for new CECs of 6 pesticides and insecticides (i.e., Fipronil, Fipronil Sulfone, Bifenthrin, Total Permethrin, Chlorpyrifos, and Diazinon), 3 flame ATTACHMENT F— FACT SHEET F-66 ORANGE COUNTY SANITATION DISTRICT ORDER NO.

CA0110604 COLLECTION SYSTEM & OUTFALLS retardants (i.e., TDCPP, TCEP, and TCPP) and 12 per- and polyfluoroalkyl substances (PFAS) compounds. With regard to PFAS compounds, POTWs are potentially significant receivers of PFAS from various sources, including disposal of landfill leachate and firefighting foam, results in PFAS in the influent to POTWs. Typical POTW treatment systems are not designed to remove PFAS, and therefore, the discharge from POTWs, especially those with industrial inputs, are possible contributors of PFAS to the surface waters. Based on the State Water Board's PFAS analytical data obtained from PFAS Investigative Orders, 12 PFAS compounds (i.e., PFDA, PFDoA, PFNA, PFHxA, PFHpA, PFDA, PFTA, PFTrDA, PFUnA, PFBS, PFHxS, and PFOS) are included in this Order/Permit to identify and understand PFAS in wastewater. 2. Outfall and Diffuser System Inspection This survey investigates the condition of the outfall structures to determine if the structures are in serviceable condition to ensure their continued safe operation. The inspection frequency has been increased to twice per permit term as the 120-inch outfall approaches the end of life in 2021. The data collected will be used for a periodic assessment of the integrity of the outfall pipes and diffuser system. 3. Discharge Monitoring Report-Quality Assurance (DMR-QA) Study Program Under the authority of section 308 of the CWA (33 U.S.C. § 1318), USEPA requires major and selected minor dischargers under the NPDES Program to participate in the annual DMR-QA Study Program. The DMR-QA Study evaluates the analytical ability of laboratories that routinely perform or support self- monitoring analyses required by NPDES permits. There are two options to satisfy the requirements of the DMR-QA Study Program: (1) The Discharger can obtain and analyze a DMR-QA sample as part of the DMR-QA Study; or (2) Per the waiver issued by USEPA to the State Water Board, the Discharger can submit the results of the most recent Water Pollution Performance Evaluation Study from its own laboratories or its contract laboratories. A Water Pollution Performance Evaluation Study is similar to the DMR-QA Study. Thus, it also evaluates a laboratory's ability to analyze wastewater samples to produce quality data that ensure the integrity of the NPDES Program. The Discharger shall ensure that the results of the DMR-QA Study or the results of the most recent Water Pollution Performance Evaluation Study are submitted annually to the State Water Board. The State Water Board's Quality Assurance Program Officer will send the DMR- QA Study results or the results of the most recent Water Pollution Performance Evaluation Study to USEPA's DMR-QA Coordinator and Quality Assurance Manager.

Orange County Sanitation District Page 1 of 3 Printed on 8/18/2021 powered by LegistarTM File #: 2021-1708 Agenda Date: 8/25/2021 Agenda Item No: 7. OC San has exercised this option in the past because it has proven to be a cost-effective method of collection. To collect the charges on the tax roll it is necessary annually to: 1. File a report with the Clerk of the Board identifying each parcel of real property receiving OC San's services and the amount of the charge; and 2. Provide notice and conduct a public hearing on the report. RELEVANT STANDARDS • Maintain a culture of improving efficiency to reduce the cost to provide the current service level or standard PROBLEM The California Health and Safety Code requires a public hearing on the annual report of charges and mechanism to collect sewer fees. PROPOSED SOLUTION Provide notice of and hold a public hearing on annual charges and adopt a Resolution directing the County Tax Collector-Treasurer to include local and regional sanitary sewer service charges on the tax roll. TIMING CONCERNS Special Assessments are due to the County Auditor-Controller in August to be included on the tax roll. RAMIFICATIONS OF NOT TAKING ACTION Approximately $318 million of sanitary sewer service charges would not be collected on the County tax roll. PRIOR COMMITTEE/BOARD ACTIONS Similar hearings are conducted annually to enable OC San to collect local and regional sanitary sewer service charges via special assessments on the tax roll. June 2020 - Board of Directors reduced the approved Single Family Residential (SFR) rates, Multi- Family Residential (MFR) rates, and Industrial Discharges Charge for Fiscal Year 2020-21. March 2018 - Board of Directors approved the Multi-Year Regional Sewer Service Charge Schedule. FINANCIAL CONSIDERATIONS Collecting sanitary sewer service charges on the County tax roll is the most efficient and cost- effective way of collecting these charges from property owners.

Over those years the Sanitation District has been adapting itself to the changing requirements and needs of the communities it serves. We have moved from an organization exclusively focused on preservation of public health to a world class resource recovery facility which protectsthe public health and the environment in ways ourfounders could never imagine. This on-going evolution is the intentional outcome of a very deliberate strategic planning process that has been in place at the Sanitation District from the very beginning. From the "Waste Water Disposal and Reclamation for the County of Orange" in 1947 to the Master Plans of the 1980s to the current Strategic Plan, the Sanitation District has always taken the long view to craft a progressive vision and build the necessary infrastructure and staffing to deliver world class service. This forward-thinking vision ofthe Sanitation District begins with the Board of Directors. The Board of Directors of the Sanitation District have a long history of mapping out bold, clear visions for the staff to deliver including energy recovery facilities, water reclamation facilities and partnerships, innovative odor control facilities, full secondary treatment levels, urban runoff beach protection partnerships, and the world's largest indirect potable water reuse facility. I would like to thank the current Board of Directors for continuing the legacy of leadership in strategic planning and innovation. Your commitment and leadership drive the Sanitation District to continue to innovate and meet the challenges facing our region. I look forward to working together to accomplish all the initiatives in this Strategic Plan. Sincerely, 12� "w `V James D.

STRATEGIC PLAN■NOVEMBER 2019 m Budget Control and Fiscal Discipline Policy Summary Policy Statement The Orange County Sanitation District(Sanitation District) will prudently manage the public funds that it collects. It will take a long-term planning approach to its facilities and rate setting that provides a stable setting program, prudent reserves, and pay-as-you-go philosophy for operating and replacing capital expenses. Background The Sanitation District manages nearly$500 million annually.These funds support the Sanitation District's operating, capital, and debt expenditures.The Sanitation District focuses its fiscal policy around three distinct areas: Revenues, Portfolio Management, and Debt Management.These areas are described in the Budget, Investment Policy, and Debt policy all of which are updated annually. Current Situation Revenues The majority of the Sanitation District's revenue is generated by user fees and charges. Currently,the Sanitation District fees are in the lower third of its comparison agencies'. The Sanitation District's revenues come from three general areas: Fees and Charges (74%), Property Taxes (21%) and other smaller revenue sources (5%). • Fees and Charges: User fees are ongoing fees for services paid by Single Family and Multifamily customers connected to the sewer system.Also included in this category are Permit Fees (User fees paid by large industrial and commercial business owners connected to the sewer system and Capital Facility Capacity Charges (CFCC) (a one-time charge imposed at the time a newly constructed building or structure is connected to the Sanitation District system).The Sanitation District policy has been to focus on cost recovery while keeping fees as low as possible. • Property Taxes:The Sanitation District receives a share of the basic property tax levy proportionate to what was received in the 1976 to 1978 period less $3.5 million allocated to school districts.These funds are dedicated to the payment of debt service. • Other Revenue: Other Revenue includes Interest Earnings, Intra-District Transfers and small revenue sources. Portfolio Management The Sanitation District Investment Policy is governed by three tenets: • Safety:The safety and preservation of principal is the foremost objective of the investment program. Investments shall be selected in a manner that seeks to ensure the preservation of capital in the overall portfolio.This will be accomplished through a program of diversification and maturity limitations. • Liquidity:The investment program will be administered in a manner that will ensure that sufficient funds are available for the Sanitation District to meet its reasonably anticipated operating expenditure needs. • Return on Investments:The Sanitation District's investment portfolio will be structured and managed with the objective of achieving a rate of return throughout budgetary and economic cycles, commensurate with legal, safety, and liquidity considerations. The Sanitation District's investments are separated into two distinct portfolios, Long-term and Short- term,with a primary focus on the Long-term portfolio. mSTRATEGIC PLAN■NOVEMBER 2019 The Long-Term portfolio always focuses on four elements, duration, sector allocation, term structure, and security selection. Duration • Typically,the Sanitation District keeps the duration of a portfolio 'close' to the benchmark duration as we feel the benchmark duration is consistent with the risk tolerance of the strategy. • The investment policy of the Sanitation District stipulates the average duration must not exceed 60 months and be within 80-120% of the benchmark. • Historically the deviation of the long-term portfolio versus the benchmark is close to 5%. Large deviations in the duration of the portfolio compared to the benchmark are an anomaly. Sector Allocation • The Sanitation District takes an active approach to asset allocation, differentiating our holdings versus the benchmark,with typically a modestly higher risk exposure compared to the benchmark. • Some of the asset classes we find more attractive in the current investing environment include Corporate notes,Asset Backed Securities, and Treasury notes relative to the Agency and Supranational sectors. • The sector allocation of the portfolio will evolve over time as our outlook for the various eligible investment options changes. Term Structure • The Sanitation District manages the term structure of the portfolio by focusing on either a bullet, ladder or barbell structure, relative to the benchmark. • For most of 2018 the structure was gravitating towards more of a bullet structure in light of the change in the sharp of the yield curve, with short term interest rates moving higher at a greater velocity than longer maturity securities. • Currently, with the yield curve very flat,we are migrating back towards more of a barbell structure, with new purchases focused at the short and long end of the eligible maturity distribution. We also find the middle to the maturity distribution, near the three-year maturity point,to be the most expensive from an absolute and relative value perspective, further supporting the barbell structure. Security Selection Within the Corporate and Asset Backed sector,the Chandler team focuses on adding stability to improve credits to be consistent with the overall investment objective of safety, liquidity, and return. • As a Corporate holding becomes more seasoned, with a short maturity, it is often utilized as a 'source of funds' to facilitate new holdings in the portfolio. • Typically,Asset Backed securities are held to maturity, but in the event of a liquidity need and/or a deteriorating credit situation we would look to reduce the exposure. The Sanitation District allocates to the Agency and Supranational asset classes when we find the spread over a like maturity Treasury notes to be attractive. • Considering the lack of issuance in the Agency sector since the financial crisis,the relative value of the sector has become more challenging. • The Sanitation District has a core view that the Supranational Asset class should offer a modest spread concession to the Agency sector, and the team is typically active in the sector when the additional spread pick-up is compelling. STRATEGIC PLAN 0 NOVEMBER 2019 Across all asset classes,the Sanitation District will remove exposure to a security that is faced with a deteriorating credit situation and/or trading at an irrational valuation where a swap into an alternative security will be beneficial to the portfolio over a reasonable investment time horizon. Debt Management Due to the magnitude of the capital improvement program,the Sanitation District has utilized a combination of user fees, property taxes and debt to meet its total obligations and maintain generational equity. It is the Sanitation District's policy not to issue any new additional debt for any existing obligations. However,the Sanitation District will actively review opportunities to refinance existing debt where possible provided the new refinancing results in a lower total cost and/or shortens the length of the obligations. The primary debt financing mechanism used is Certificates of Participation (COP). COPs are a repayment obligation based on lease or installment sale agreements.As of July 1, 2019,the total outstanding COP indebtedness was $973 million with a blended interest rate of 3.05%. It is anticipated that the debt will be paid off by 2044. Future Policy Statement The Sanitation District will effectively manage its revenues and expenses to support all OCSD operating and capital activities while maintaining a fair and reasonable rate structure.The Sanitation District will maintain reserves and available resources to ensure the access to funds as needed and guarantee payment of all outstanding debt issuances.The Sanitation District will manage its investment by focusing on safety, liquidity and return on investment, in that order of priority. Initiatives to Support Progress Toward the Policy Goal • Maintain a rate setting program that keeps OCSD in the lower third of our comparative agencies. • Maintain a "Pay as You Go" approach to fund current operating expenditures. • Maintain a portfolio management approach that focuses on safety, liquidity and performance in that order. • Continually look for ways to reduce total debt payments without lengthening its term. • Ensure that no new debt issuances are used to support the currently programmed capital expenditures and that all existing debt is paid off by 2044. ®STRATEGIC PLAN 0 NOVEMBER 2019 Asset Management Policy Summary Policy Statement The Orange County Sanitation District(Sanitation District) will assess and manage the collection system and treatment plant systems and assets to improve resilience and reliability while lowering lifecycle costs.This will be accomplished through adaptive operation, coordinated maintenance and condition assessment, and planned capital investment. Staff will balance maintenance, refurbishment, and replacement strategies to maximize useful life, system availability and efficiency. Background The Sanitation District is a regional governmental agency principally chartered to protect the public health through collection and treatment of wastewater.The governing Board of Directors has defined this role to include the recovery and utilization of resources from wastewater for the public good as a part of that mission.The environmental impact mitigation of the human activity of 2.6 million people and the natural drainage of the 471 square miles the Sanitation District serves is our principal concern. The Sanitation District owns and operates extensive facilities to achieve its mission.The Sanitation District estimates the replacement value of the civil, mechanical, and electrical assets in its collection system, Plant No 1 in Fountain Valley, and Plant No. 2 in Huntington Beach to be nearly$11 billion. The Sanitation District has been building the piping, pumping, and treatment infrastructure it utilizes for more than sixty-five years. It is necessary to expand, renew, replace, demolish, and rebuild components of the system to deal with wear and tear and meet new challenges. The early years for the Sanitation District were characterized mostly by capacity expansion to meet the challenges of increased flows as the county grew.The late 1970s to the 2000s were more defined by improved levels of treatment.The last ten years have been focused on increasing the level of resource reuse. One of the key success factors for the Sanitation District has been the ability to upgrade and repurpose its operating facilities to accomplish high levels of treatment and reuse. Current Situation The Sanitation District is a highly planned, forward-looking organization.The collection system and each of the treatment plants are broken down into granular functional parts. Each part is well defined and future requirements are estimated.The Sanitation District has a detailed understanding of what is owned, what condition it is in, and how it is capable of performing. The collection system is made up of independent pipe networks that were installed by the former independent sanitation districts to deliver flow to the joint treatment works. Generally speaking, the natural watershed drainages in the service area are served by major trunk sewer systems.The Sanitation District has worked with member city and agency staff to understand future development plans, flow estimates, and has collected historical inflow and infiltration rates during wet weather events to assure adequate flow carrying capability exists in each trunk sewer system.The Sanitation District also factors in the effects of drought and lower domestic water usage rates to make sure the sewers operate properly at low-flow rates. The treatment plants are broken down into the discrete process units that make up the whole. Each plant has a headworks unit that brings in flow and does preliminary treatment, a primary treatment unit which does gravity settling, multiple biological secondary treatment systems, solids handling and dewatering, power generation and distribution utilities, water and air system utilities, and an outfall system to release treated water to the ocean. Each plant can treat 320 million gallons per day of wet weather flow, but only 185 million gallons total on average is treated.The Sanitation District must always maintain the ability to treat both the average flow and peak wet weather flow. The Sanitation District understands that every asset has an expected life. Electrical systems are generally limited by component obsolescence to 20 years of life. Mechanical and coating systems are also generally limited by erosion, corrosion, and wear to 20 years of life. Civil structures and pipes are generally limited to 60 to 80 years of life if maintained on a regular basis. STRATEGIC PLAN 0 NOVEMBER 2019 With this in mind,the Sanitation District has created a facilities master plan that plans to renew or replace facilities on this regular basis. Collection system projects are driven by growth projections or condition findings. Pipes are upsized or renewed based on flow projections, corrosion observation, coating system failure, or the ability to increase reclamation.The 15 regional pump stations are renewed on a more frequent basis due to the mechanical wear and tear and electrical component obsolescence needs, about every 25 years. The master plan for the treatment plants is much more dynamic. In addition to the electrical, mechanical, and civil asset considerations,there is also the need to meet new requirements.The new requirements are driven by regulatory agencies or by the Board of Directors to change a discretionary level of service. Examples include: capacity demands (more water, more solids), lower discharge requirements (lower BOD/TSS to the outfall, lower nutrients to the ocean), more water for reclamation, better energy conversion of solids, and many more.The 2017 Facilities Master Plan took a snapshot in time looking at the anticipated needs and levels of service to lay out a detailed project plan to morph the Sanitation District infrastructure overtime to meet the expectation. Renewal or replacement projects with costs and schedules were laid out for each individual unit of the treatment plants to address capacity, condition, level of service, and anticipated new regulatory drivers. Future Policy Statement The Sanitation District will continue to invest in the infrastructure necessary to meet its mission. The Sanitation District will seek to provide its required level of service at the minimum lifecycle cost for its collection and treatment systems.The 2017 Master Plan was the snapshot basis of the Capital Improvement Plan, but the Asset Management Plan is the means to update and modify the Capital Improvement Plan to meet new requirements and conditions as time goes by. The Sanitation District will understand in a transparent way:what it owns,the condition of those assets, the capacity of collections and treatment required,the level of service required by its regulators and Board of Directors and will anticipate new regulations that may require system improvement.This understanding will drive coherent operations, targeted maintenance, and capital investment strategies to assure resilient, lowest lifecycle cost compliance with the requirements. Operations is committed to optimizing the operation of the systems to extend equipment life and minimize energy and chemical utilization,while meeting all regulatory and level-of-service requirements. Maintenance is committed to maintain the installed assets in a ready state for operations. Maintenance will seek to balance individual component preventive maintenance, repair, and renewal in harmony with the Capital Improvement Program (CIP).The CIP is based on the Master Plan, modified by the annual Asset Management Plan, and will execute the projects to install, renew, or replace trunk sewers or treatment plant units on a scheduled basis. Asset Management at the Sanitation District is the living management of the operation strategies, maintenance plans, and implementation of the Capital Improvement Plan.The Sanitation District will find creative ways to maximize asset life or meet new capacity or level of service goals through operations and maintenance.The Sanitation District will annually reassess its condition, capacity, level of service, and regulatory conditions to drive operations and maintenance practices and modify the Capital Improvement Plan projects. Initiatives to Support Progress Toward the Policy Goal • Create an annual Asset Management plan documenting the condition of the collection system and treatment plants, and upcoming maintenance or capital projects. • Coordinate the efforts of operations, collections, mechanical maintenance, electrical maintenance, instrument maintenance and engineering through process teams to assure the Sanitation District's resources are focused on the high priority work functions. • Maintain a 20-year forecast of all CIP projects needed to maintain or upgrade the Sanitation District's nearly$11 billion in assets on a prioritized risk basis to establish rate structures. mSTRATEGIC PLAN 0 NOVEMBER 2019 Cybersecurity Policy Summary Policy Statement The Orange County Sanitation District(Sanitation District) must maintain adequate cybersecurity (information technology security)techniques that protect computer assets, networks, programs, data, and industrial control equipment from unauthorized access or attacks that are aimed for exploitation. Background Developing an effective, sustainable cybersecurity program is a pressing challenge for organizations of all sizes.The reasons behind the scope of the challenge are many. Cyber risk continues to grow at an exponential rate with routine attacks from nation states, criminal elements, hacktivists, and insider threats.The bottom line is cybercrime pays.The booming cybercrime economy is productizing malware and making cybercrime as easy as shopping at Amazon. With this easy access to cybercriminal tools and services, enterprises are experiencing rapid increases in the volume, scale, and sophistication of cyberattacks. Complex and dynamic information security disciplines are subject to continuous changes in the business,technology and threat environments. Many organizations will struggle to implement security programs that support continuous improvements in this challenging environment. Current Situation The Sanitation District has evolved over recent years from dedicating less than half of a position towards cybersecurity,to one position,to currently two full-time positions.The Sanitation District's cybersecurity portfolio consists of strategic policy management, defense in depth practices, periodic risk assessments, ongoing awareness communication and operational (e.g., security monitoring and incident response, threat and vulnerability management, user provisioning) processes. For example: • Cybersecurity Awareness and Training Program - The Sanitation District understands that our employees are our best line of defense in protecting and defending our enterprise from attack. We have built a comprehensive security awareness program by focusing on four critical functions: phishing attack simulations and reporting, quarterly education requirements,targeted training for IT developers and SCADA engineers, and pervasive communications utilizing internal communication tools. • Vulnerability Management— IT staff subscribe to and monitor security advisories and threat bulletins from Microsoft, US-CERT, ICS-CERT, KnowBe4, Cisco, and other vendors to understand and manage new vulnerabilities. All internet accessible servers and applications are scanned weekly for vulnerabilities and remediated as necessary. Microsoft operating system and application patches are deployed monthly while third party updates are deployed weekly. We use a vulnerability platform for continuous assessment of our security and compliance posture. • Intrusion Detection and Response —We have implemented several security solutions to be able to detect, prevent and respond to malicious network activity.These include firewalls, intrusion prevent systems, web security gateway, and next-generation anti-malware. In addition, we also have user behavior analysis tools to identify insider threats and ransomware activity. • Privileged Access Management Program —We use a privilege access management solution to remove and manage local administrative rights on workstations/servers to prevent lateral movement.The solution is also used to protect, control, and monitor privileged access across files and systems. • Backup and Restore Capabilities— IT practices a 3-2-1 backup strategy: 3 - Keep three copies of critical data 2- Have your data on two types of media 1 - One copy must be offsite and offline STRATEGIC PLAN■NOVEMBER 2019 Restores are performed on at least a weekly basis in response to customer incidents. Disaster Recovery Testing is performed monthly by selecting a major system and testing restore capabilities of that system to our secondary treatment facility, as well as our remote site. We sandbox the restores and provide access to our application subject matter experts to conduct application-specific testing.These tests are logged and kept for auditing and management purposes. • Security Incident Response —An incident response plan is an organized approach to handle a cyberattack. We have developed an incident response plan, playbooks and procedures for various attacks as well as trained IT security staff. In addition,there are external contacts we can call for assistance including the FBI, Department of Homeland Security and organizations that specialize in incident response like Mandiant, Cylance, and Microsoft. • Security Assessments —The purpose of a security assessment is to identify the current security posture of a system, network, or organization.The assessment provides recommendations to improve the security posture by mitigating identified risks. Our goal is to do one or two a year.The two most recently conducted assessments are the Office 365 Security Assessment from Microsoft in April 2019 and the Center for Internet Security Control Gap Assessment in July 2018. Future Policy Statement The main objective of our information security program is the establishment of a continuous, iterative regimen of planning, building, running and governing security capabilities that are derived from business requirements. Our security program cannot be a static entity. It must be adapted and continuously refined to keep pace with the ever-changing threat environment and changes in how the Sanitation District adopts digital business practices. Cybersecurity incidents are inevitable. Mistakes and/or a lack of preparation in the response can have serious repercussions.The ability of an organization to respond effectively to a security incident is a direct result of the time spent preparing for such an eventuality. If you fail to prepare,then you effectively prepare to fail.The Sanitation District will be prepared.This will be accomplished by the following proposed initiatives. Initiatives to Support Progress Toward the Policy Goal • Conduct various tabletop exercises to determine the organization's ability to respond to a targeted cyberattack and to improve the quality of the response, should an attack occur. • Evaluate, enhance and monitor network security including activities to protect the usability, reliability, integrity and safety of the network by developing Security Operations Center capabilities that support continuous monitoring and is responsible for the continuous threat protection process. • Conduct a comprehensive third-party cybersecurity operations assessment(Red Team). A thorough Red Team engagement will expose vulnerabilities and risks regarding: • Technology— Networks, applications, routers, switches, appliances, etc. • People — Staff, independent contractors, departments, business partners, etc. • Physical— Offices, warehouses, substations, data centers, buildings, etc. �. STRATEGIC PLAN 0 NOVEMBER 2019 Property Management Policy Summary Policy Statement The Orange County Sanitation District(Sanitation District) owns and operates assets throughout its service area located in property owned in fee, through easements and in the public right-of-way.The Sanitation District will identify and protect all of its property rights to assure that its assets are not encumbered or encroached upon so that the facilities may be properly operated, maintained, upgraded, and replaced. Background The Sanitation District owns and operates more than $10 billion in assets.A portion of those assets include buildings, easements, rights of way and other encroachments. OCSD has recently sold and purchased property to support its efforts.The Sanitation District does not maintain expertise in the real estate discipline. As these transactions are limited and not core to OCSD, it has been determined that it is more cost effective to augment the Sanitation District resources with contracted specialized real estate services. Current Situation The Sanitation District manages its physical property and property rights.Additionally, it manages landscaping, building maintenance, security and building maintenance. District staff primarily manages these activities. Future Policy Statement The Sanitation District will effectively manage its assets and proactively research and maintain all encroachments, encumbrances and easements. Many of these activities are not core to OCSD's mission. The Sanitation District will maintain sufficient resources using a combination of contracted specialized real estate and property management services and internal staffing.Although OCSD is not in the business of managing property as a revenue enhancement or core activity, it does own and operate millions in physical property and property rights. Initiatives to Support Progress Toward the Policy Goal • The Sanitation District will review its property rights to identify encroachments or encumbrances that restrict operation, maintenance, inspection or emergency repair access. Staff will work with identified parties to remove encroachments or encumbrances. • Staff will consolidate real estate and property management activities to maximize its resources and effectiveness. With the completion of the property rights and real estate assessments,the Sanitation District will evaluate the various resources available and develop an appropriate resource management plan to assess and maintain its property assets STRATEGIC PLAN■NOVEMBER 2019 1 t .-. 1 r 1 J►.v .IL •4f ■.��1 - �1 - ��.. ��� i 1' I I i i ,. {F �i.j�. i / 7•i }�f\2�X'��'M. /'Ai/'�i 1 �•� � �.� 11, 1' I' 1, tll I•tii. 1 �• I _*�- �_\RY�I�I �M �n. ♦i/ I✓ 1 Mi Y�' !v 441 7 ! lavt`� is STRATEGIC PLAN■NOVEMBER 2019 m Energy Independence Policy Summary Policy Statement The Orange County Sanitation District(Sanitation District) will strive to be a net energy exporter. Electrical,thermal, and methane gas generation will be maximized. Energy utilization will be minimized using sound engineering and financial principles. Background The Sanitation District must balance the impacts of its operation between land, air, and water. For example, as a water focused utility,the Sanitation District seeks to produce the cleanest water possible to minimize the impacts of human activity on the ocean, as well as to renew freshwater resources for further domestic and commercial use.A natural result of cleaning this water is the separation and concentration of constituent solid and gaseous materials.These solid and gaseous products can impact land and air.The balance of impact on land, air, and water are shifted by application or creation of energy through chemical, biological, or thermal conversion techniques. The Sanitation District is also committed to be a good neighbor. As such, significant amounts of energy are spent capturing and converting odorous air and vapor streams.The Sanitation District has pursued a comprehensive program to cover and seal its liquid and solid processes.Air streams are ducted to large fans which move thousands of cubic feet of foul air per minute through chemical, biological, and activated carbon beds to scrub the air of odorants that are regulated or may be perceived as a nuisance by the community. The Sanitation District has utilized an anaerobic digestion process that relies on biological conversion of solid organic material to methane and carbon dioxide gas.The methane is converted to electrical and heat energy in power plants for internal use.The Sanitation District's secondary treatment system is another example of using energy to convert water impacts to air emissions. Approximately 23% of the Sanitation District's energy usage within the treatment process is devoted to aerating water so biological agents can convert soluble organic material to nitrogen and carbon dioxide.The generation of energy itself creates an impact on the environment in air and thermal emissions. Current Situation The potential exists to further shift environmental impacts between land, air, and water through the utilization of energy.The Sanitation District is an environmental steward that seeks to balance and minimize overall impact by efficiently utilizing the energy inputs to its processes and maximizing the harvesting of energy available in the incoming wastewater. On the energy use side of the ledger,the Sanitation District invests prudently in lifecycle energy efficiency to minimize the use of energy to achieve its mission. Pumping systems to lift water and move material for premium efficiency.Thermal energy is harvested from power production for use in the process and to heat and cool occupied buildings.Aeration compressors and diffusers are selected by overall efficiency. Lighting systems are upgraded over time to more efficient technologies and lighting levels are balanced between safety and security needs versus energy utilization and light pollution concerns. Facility designers and operators make careful choices regarding the utilization of every watt of electricity, BTU of heat, and therm of gas consumed. On the energy generation side of the ledger,the Sanitation District seeks to maximize the internal creation of energy.The primary source of energy creation is in digester gas, also called biogas, which is mostly methane. Organic solids collected and concentrated in the water treatment processes are converted biologically to biogas composed of 65% methane,34% carbon dioxide, and other trace constituents.The Sanitation District has been using this technology since the 1950s. Research has been ongoing since that time to maximize the production of digester gas. Some of the areas of research include improved mixing and heating; improved feeding; chemical addition to limit trace pollutant production; introduction of food waste; injection of fats, oils, and grease; and cell lysing. mSTRATEGIC PLAN 0 NOVEMBER 2019 The Sanitation District cleans the biogas and converts this biogas into electricity, heat, and exhaust gas. The exhaust gas is regulated ever more tightly for nitrogen compounds, carbon monoxide, particulates, and volatile organic compounds which require costly and performance degrading engine control technologies.This is another example of an air impact/energy trade off.These internal systems of energy harvesting provide roughly 66% of the Sanitation District's electrical demand and 92% of the Sanitation District's thermal demand in the treatment plants.The Sanitation District can shift the digester gas between treatment plants via an interplant pipeline and has roughly 8 MW of additional generation capacity if more gas is produced. In addition,the Sanitation District is installing electrical battery storage capacity.This system is primarily in place to lower operating cost by importing electricity for charging during low-cost nighttime hours and discharging that energy for process use during peak-cost hours.The slight energy loss due to system inefficiencies is outweighed by the cost savings and benefit to the region by lowering the peak demand of the Sanitation District by up to five megawatts. Future Policy Statement The Sanitation District seeks to be energy independent by self-generating all the electrical and thermal energy necessary to sustain its operations.This will be accomplished by economically minimizing its utilization requirements and maximizing energy harvested from the wastewater it receives.The Sanitation District will also study and use photovoltaic cells in non-process areas where it makes economic sense. Energy independence will improve the Sanitation District's environmental impact and improve its operational reliability and resiliency. When the Sanitation District has achieved energy independence, it will seek to make excess biogenic or green energy available to external users via gas sales, power grid exports, or transportation fuels.The State of California has set goals for renewable energy utilization for electrical production and hydrogen transportation fuels.The Sanitation District's biogas is viewed favorably in these industries to meet the State of California targets.The Sanitation District is working very diligently and creatively to maximize the production of gas and reduce its own energy needs, but energy independence is the first goal which has not yet been met. Staff recommends that innovative research continue to maximize energy harvesting and to minimize energy inputs first to make the Sanitation District energy independent in the most basic mission of protecting the public health and the environment. Once this has been achieved, excess energy can be made available for meeting the State of California's goals for the electrical grid and transportation fuels. Initiatives to Support Progress Toward the Policy Goal • Maximize the anaerobic digestion conversion of organics to methane through receipt of food waste and operational techniques. • Investigate and install energy storage and photovoltaic systems where practical to achieve energy independence/resilience. • Continue to support the conversion of biomethane into electricity and heat for process use. Improve systems as necessary to comply with air regulations.

Background The Sanitation District owns and operates extensive wastewater collection and treatment facilities valued at nearly$11 billion.The Sanitation District service area faces special challenges because of the geographic location of its facilities.These challenges include: its position on and near seismic risk factors, its proximity to the Pacific Coast, adjacency of its treatment facilities to the Santa Ana River, and being served by increasingly fragile energy utilities. The Sanitation District's facilities are situated on or near several seismic risk factors. Plant No. 2 is located directly on top of the Newport-Inglewood fault. Both plants and the collection system are influenced by many adjacent major and minor faults capable of delivering damaging energy. Both of our treatment plants and the majority of our collection system sit on top of silty, alluvial soils that can have the effect of amplifying the earth motion and risk liquefaction during a seismic event.The Sanitation District has invested significantly over the last 50 years to improve the soils,foundations, and structures to mitigate these seismic risks.As geotechnical and structural knowledge and building codes progress, upgrades and facility replacements will be necessary. Another seismic risk associated with having a treatment plant and several pump stations located on the Pacific Coast, is the risk of tsunami inundation.The Sanitation District has been working with and reviewing the plans of the City of Huntington Beach and the City of Newport Beach to understand and quantify this risk.The American Society of Civil Engineers (ASCE) has created a new standard, ASCE 7-16, to layout design parameters for lateral forces and inundation zone associated with potential tsunamis. The Sanitation District understands that climactic factors we face change widely over time.The Sanitation District's systems must perform in extreme wet weather situations (atmospheric rivers), extreme dry weather conditions (drought), extreme tidal conditions (king tides, rising sea levels), as well as high and low temperature extremes.The Sanitation District generally designs for historical and expected "average conditions"for optimal performance but must also assure operations for extreme weather events. The Sanitation District serves a critical public health role. Its operations must be reliable 24 hours per day, 365 days a year. Electricity, and to a lesser extent natural gas, are necessary for pumping and treatment operations. Both electricity and natural gas supplies have become increasingly vulnerable to interruption. Electricity deliveries are more vulnerable due to wildfire outage criteria, loss of local generation assets, aging infrastructure and extreme weather events. Natural gas supplies are more vulnerable due to the loss of local storage capacity, aging infrastructure, line corrosion, and more stringent regulatory requirements.The Sanitation District has significant capacity to self-supply critical energy requirement for extended periods. Current Situation The Sanitation District has spent considerable effort quantifying its seismic, climate, and utility supply risks. Several key studies have been initiated and will be completed in the next two years.The most acute risk factor faced by the Sanitation District is seismic risk. Climate and utility supply risks are more accurately described as chronic risks. Seismic risk factors include ground shaking, liquefaction, lateral spreading, and fault rupture. Both treatment plants are situated in historic riverbed with poor soil conditions.The collection system STRATEGIC PLAN 0 NOVEMBER 2019 is vulnerable to failures during seismic events.The state of the art for seismic design has changed greatly over the Sanitation District's history and will continue to do so. Many of our critical structures were designed or installed prior to the great learning that occurred in the earthquakes of the 1990s. Significant effort has been expended to better characterize the soil conditions under our treatment plants and pump stations. Projects to refurbish or replace existing unit processes are, or soon will be, scoped and budgeted to provide enhanced seismic resilience.These measures include soil mixing to stiffen the soil,various foundation designs and building structure improvements. Tsunami resilience and flooding protection can go hand in hand.To a great extent,these two risk factors can be mitigated in the same way.The Tsunami guidelines for inundation in ASCE 7-16 are a reasonable peer reviewed standard. By complying with this standard for Huntington Beach and Newport Beach, the Sanitation District will be reasonably prepared for flooding caused by extreme storm events and conservative sea level rise estimates at Plant No. 2 and pump stations in the City of Newport Beach. The Sanitation District has also expended significant effort to prepare for the effects of weather extremes on its operations. Extreme wet weather impacts operations. Inflow and infiltration during intense storm activity have multiplied average dry weather flow rate by up to three times in recent years.The Sanitation District has significant wet weather capacity and will continue to maintain a 640 million gallon per day influent and outfall capacity which is roughly 3.5 times our average dry weather flow. Historically high rains as seen in 1863 and 1938 will push our systems to the limit. The Sanitation District has also adapted its systems to perform in extreme dry weather.The Sanitation District in cooperation with OCWD operates the largest potable water reuse system in the world.This is made possible by replumbing our treatment plants and adding new smaller pump stations to deal with extreme low outfall flow rates in the morning hours.The Sanitation District also has, and continues to grow, the ability to shift influent flow between its treatment plants which creates additional resilience for risk factors. Finally, on the topic of utility supply, the Sanitation District built redundant supplies for its most critical needs: electricity, natural gas and water.The Sanitation District has maintained three sources of electricity supply for more than 25 years.The treatment plants can be supplied with power from Southern California Edison,the Sanitation District's Central Generation Plants or on-site diesel generation systems to maintain basic operation to protect public health. In terms of natural gas,the Sanitation District has been producing bio-methane through anaerobic digestion since the 1950s with enough capacity to provide electricity and necessary process heat. Future Policy Statement The Sanitation District will continue to build and improve its facilities to meet the seismic, climate and energy infrastructure risks that it faces with a long-term, planned approach.Acute life-safety risks that are identified or facilities that are damaged or fail in a catastrophic event will be addressed very quickly. However, it is not practical to update $11 billion in facilities every time a code is updated, or new climate change estimate is released.The Sanitation District will stay abreast of code and climate change estimates as they occur and will implement improvements or replacements to facilities on a long-term basis in line with its asset management practices.The Sanitation District generally plans to refurbish or replace its mechanical and electrical assets every 20 to 25 years with an average capital improvement investment of$250 million per year. The Sanitation District facilities are designed to meet industry codes. As time goes on and codes are updated, it is not required to upgrade existing facilities to meet those latest codes unless there is a mandate to do so, or a risk in not doing so is recognized.The Sanitation District will accept some incremental risk in having some facilities that are not necessarily compliant with latest building codes or subject to increased greater risks until a project to rehabilitate or replace these facilities is developed.All of the Sanitation District's facilities have a planned life span with two to three refurbishment cycles. Identified seismic or flooding vulnerabilities may drive a replacement versus refurbishment decision in the normal capital planning process. mSTRATEGIC PLAN 0 NOVEMBER 2019 The Sanitation District will continue to aspire to energy independence which will help mitigate vulnerabilities to loss of electrical and gas utilities. In addition,the Sanitation District will continue to maintain third level, diesel generator, electrical supply capability for critical loads. On-site diesel storage will provide up to three days of power to run the plants. Pump stations diesel generation will be site specific in its design based on flow risks, hydraulic storage capacity, and site constraints. Either on- site generation or quickly deployable mobile generators will provide emergency power for up to days at a time. Initiatives to Support Progress Toward the Policy Goal • Complete an engineering study of the seismic vulnerabilities of the treatment plants. Incorporate necessary upgrades into future capital improvement projects. • Complete the biannual high flow exercise to assure readiness for a high flow event. Maintain a higher level of readiness October 15 through March 15 and in advance of predicted significant rain events. • Study the potential impact of tsunami and changing climate conditions including flooding due to high tides and heavy rain events. - � r� h �•s� - STRATEGIC PLAN 0 NOVEMBER 2019 Food Waste Treatment Policy Summary Policy Statement The State of California limits the volume of organic waste that may be diverted to landfills.The Orange County Sanitation District(Sanitation District) will collaborate with the County of Orange, other local agencies, and waste haulers to find ways to beneficially reuse food waste, a type of organic waste to assist cities in our service area in meeting their diversion requirements while increasing the Sanitation District's energy production. Background Whether supplying secondary treated wastewater for the Groundwater Replenishment System, creating renewable energy in the form of biogas from anaerobic digestion to produce electricity, or benefiting from the use of biosolids as a soil amendment,the Sanitation District is a resource recovery agency committed to providing resilient and reliable wastewater treatment service while protecting the public health and the environment. In recent years,there has been a significant change in the regulatory landscape in California related to the diversion of organics such as food, green material, wood, paper, biosolids, digestate, and sludges from landfills. Currently, much of the state's diverted organics are being composted or used as alternative daily cover on landfills. With the phaseout of organics as alternative daily cover,the regulatory shift is creating an organics market for the wastewater sector to provide a solution to manage organics such as food waste by way of co-digestion.There is an opportunity for the Sanitation District to produce additional biogas, reducing the need to purchase electricity from the local utility. Anaerobic digestion is currently at the nexus of important State of California mandates, namely: (1) organics diversion from landfills (AB 1826 and SB 1383), and (2) increased renewable energy and fuels generation (SB 32 and SB 100).The primary alternatives for organics management are anaerobic digestion and composting— of which anaerobic digestion is the only process offering energy recovery potential. Over the next few years, California's cities and counties, along with municipal solid waste haulers, material recovery facilities, and landfills will need to develop collection, processing, and energy recovery infrastructure to address new state legislation and goals. Existing wastewater treatment plants such as the Sanitation District are uniquely positioned to play a role in the new organics marketplace since solid waste management facilities do not typically have anaerobic digesters,the energy recovery infrastructure in place, or experience regarding the management of biosolids for beneficial use. In 2017,the Sanitation District completed a comprehensive Biosolids Master Plan (Plan)that provides a roadmap and framework for sustainable and cost-effective biosolids management options and future capital facilities improvement over a 20-year planning horizon. Considering the timeliness of the regulatory mandates requiring organic diversion from landfills and increased renewable energy,the Plan evaluated the feasibility of implementing a high strength organic waste receiving program involving the co-digestion of preprocessed food waste. While food waste digestion appears to be feasible,the Sanitation District's existing infrastructure isn't well suited for receiving, handling, or digesting green waste. Current digester feed, mixing, heating, dewatering and truck loading facilities aren't designed to deal with cellulosic products in green waste.The highly fibrous material doesn't readily break down and clogs the various systems optimized for sewage sludge treatment. In addition,there are legal hurdles specified in the California Health and Safety Code, Section 4700,that must be addressed before the Sanitation District could operate a refuse transfer facility. Current Situation Project Viability The Sanitation District's Plan concluded that the costs to construct and operate a food waste receiving facility could be offset by tipping fees charged to food waste processors/haulers and by additional power ®. STRATEGIC PLAN 0 NOVEMBER 2019 generated from the increased digester gas production.The Plan recommended that the Sanitation District build an interim food waste receiving station immediately to take advantage of existing digestion and power generation capacity of approximately 150-250 wet tons per day at Plant No. 2.The Sanitation District will construct a more permanent facility in the future to coincide with the planned construction of new digesters at Plant No. 2, allowing an additional capacity to co-digest approximately 500 wet tons per day of food waste.The Sanitation District also has at least 6 MW of installed electrical generation capacity that can convert the produced digester gas to electricity and heat. Based on these recommendations, in 2018 the Sanitation District's Board approved a project(P2-124) to construct an interim (10-15 years)food waste facility to receive, store, and feed preprocessed food waste slurry to the digester complex at Plant No. 2 to generate additional digester gas.This project will be designed to accept approximately 150 wet tons per day of preprocessed food waste and will produce approximately 15 percent more methane gas for on-site energy production, resulting in a greenhouse gas reduction of approximately 10,800 metric tons of carbon dioxide equivalent annually which is equivalent to the annual greenhouse gases generated by approximately 2,000 passenger vehicles.This is consistent with the Sanitation District's Energy Independence Policy which is to strive to be energy independent by minimizing energy utilization and maximizing useful energy recovery from the sewage it receives.The interim receiving station is scheduled to be completed in 2022. The final biosolids product currently produced by the Sanitation District is anticipated to be largely unaffected by the addition of food waste slurry. Pilot testing conducted by the Sanitation District indicates that there will be increased gas production due to mixing sewage sludge and food waste feed stock, but the final biosolids product will remain largely unchanged. A draft Preliminary Design Report was issued in June 2019 for the interim receiving facility which included a viability evaluation concluding that the project is economically justifiable based on project costs and anticipated tipping fees. Final Design work has started and among other important items,the tipping fee and food slurry specifications will be further refined and validated. There are three large municipal solid waste haulers that have expressed interest in collaborating with the Sanitation District to provide preprocessed food waste for digestion. Of these,two haulers are located within the county and one is located outside the county. Another important partner for the Sanitation District is Orange County Waste and Recycling(OCWR).The Sanitation District has met with OCWR and they have expressed interest in partnering with the Sanitation District to find local solutions to meet SB 1383's organics diversion mandate including in-county biosolids management, composting, food waste co-digestion, and biogas production. Future Policy Statement Food Waste Slurry The Sanitation District will only accept a preprocessed food waste slurry.We do not have available land or air permits to handle, sort, and process solid or green wastes.The Sanitation District will work with other public agencies and waste haulers to develop an industry standard for food waste slurry that specifies water, organic, metal, plastic, and glass content requirements.A common specification for slurry will help all parties make investment decisions. Food Waste Volume The Sanitation District has identified available capacity within its infrastructure at Plant No. 2 to accommodate food waste conversion to energy.The processes impacted by food waste conversion are digestion, gas cleaning, gas compression, generation, process heating, biosolid dewatering and biosolids loading.These impacted systems have the capacity to accept 150 to 250 wet tons per day for the next ten years. Beyond ten years,the Sanitation District plans on upgrading its digestion, gas compression, and gas treatment systems. Based on the lessons learned from the interim system and the development of the food waste market,the Sanitation District plans to be able to accept up to 500 wet tons per day when the new digestion, gas compression, and gas treatment systems are completed. STRATEGIC PLAN 0 NOVEMBER 2019 The Sanitation District believes that the full implementation of the current regulations will create a food waste slurry market significantly greater than 500 wet tons per day in Southern California. Tipping Fee Basis The acceptance of food waste has the opportunity to more fully utilize the system capacity that already exists for the benefit of the Sanitation District's rate payers. The Sanitation District staff will develop a base tipping fee rate schedule for Board of Directors' approval that meets the following criteria: • Recover all capital costs to construct facilities within five years (this will allow the Sanitation District and waste haulers to properly invest in processing facilities); • Recover all on-going costs including operating cost, maintenance cost, electricity usage, biosolids dewatering, and reuse costs; • Food Waste will not be operated "for profit" but rather a cost recovered service with revenues offsetting rates and passed on to CICSD's rate payers. Food waste generated and processed within the service area will be charged the base rate and will be prioritized over food waste from outside the service area.This is justified by the fact that the underlying infrastructure of the Sanitation District is already owned by service area rate payers.The Sanitation District contracts with service area waste haulers must provide for a pass-through savings to the Sanitation District rate payers.That means waste haulers may charge for collection and processing of food waste but must disclose to their City or Special District franchise partner the Sanitation District's tipping fees and negotiate pricing adjustments as necessary with City or Special District franchise partners. if additional capacity exists, but isn't utilized by in service area users,then that capacity may be contracted by out of service area users at a premium to help offset the cost of the underlying infrastructure necessary to process the food waste. The Sanitation District will pursue grant opportunities to the extent possible to reduce the overall capital and operating cost basis for the program to reduce the tipping fee base rate. Initiatives to Support Progress Toward the Policy Goal • The Sanitation District will accept a preprocessed food waste slurry from contracted waste haulers that will be fed to existing anaerobic digesters.The Sanitation District will charge a tipping fee to offset its costs for capital construction, operations, handling, maintenance, and biosolids disposal. • Design, build, and operate a food waste receiving station. Create a specification for food waste slurry and contract with solid waste haulers to receive and process food waste. STRATEGIC PLAN 0 NOVEMBER 2019 Water Reuse Policy Summary Policy Statement The Orange County Sanitation District(Sanitation District) will seek to beneficially reuse all reclaimable water for potable, industrial, irrigation and environmental uses. Background For over 40 years,the Sanitation District and the Orange County Water District(OCWD) have partnered to beneficially reuse treated wastewater from the Sanitation District. OCWD, which serves roughly the same service area as the Sanitation District, manages and replenishes the groundwater basin in northern and central Orange County, ensures water reliability and quality, prevents seawater intrusion, and protects Orange County's rights to Santa Ana River water. Beginning in 1975,the Sanitation District contributed treated wastewater from its Plant No. 1 to OCWD for the operation of Water Factory 21, which reclaimed the treated wastewater and injected it along with deep well water into the groundwater basin to prevent seawater intrusion. In the mid-1990s, OCWD needed to expand Water Factory 21.At the same time,the Sanitation District faced the challenge of having to build a second ocean outfall pipe to discharge treated wastewater into the Pacific Ocean. Both agencies collaborated to build an advanced water purification facility to resolve these challenges. This state-of-the-art facility, known as the Groundwater Replenishment System (GWRS),took the place of Water Factory 21, and began operation in 2008.The GWRS treats secondary treated wastewater from the Sanitation District Plant No. 1 to drinking water standards and uses the purified water for both injection and percolation,through injection wells and recharge basins, as source water to replenish the groundwater basin's drinking water supplies. With approximately 75 percent of the water demand in northern and central Orange County cities coming from the groundwater basin, GWRS supplements existing water supplies by providing a new, reliable, high-quality source of water. While the original GWRS facility was initially constructed to supply up to 70 million gallons per day (MGD) of purified water,the facility was designed for an ultimate treatment and conveyance capacity of 130 MGD.The original GWRS design intent was to expand the GWRS facility in two phases— an initial and a final expansion of an additional 30 MGD of treatment capacity with each expansion.The GWRS Initial Expansion Project was completed in June 2015 and has been producing up to 100 MGD of purified water for groundwater injection and recharge.The Final Expansion of GWRS is scheduled to be completed in 2023 and will produce the maximum capacity of 130 MGD. In addition to providing treated wastewater to the GWRS,the Sanitation District also provides treated water to OCWD's Green Acres Project, which provides recycled water for landscape irrigation at parks, schools, and golf courses; and industrial uses, such as carpet dying;toilet flushing; and power generation cooling. Current Situation The GWRS currently produces 100 million gallons per day of purified water— enough water for about 850,000 people.All of the Sanitation District's Plant No. 1 secondary effluent, between 120-130 MGD, is sent to OCWD for the GWRS and Green Acres Project. However, secondary effluent from the Sanitation District's Plant No. 2 and other non-reclaimable flows, such as brine from inland desalters and GWRS's reverse osmosis process, and the Sanitation District's process sidestreams, continue to be released into the ocean. In 2016,the Sanitation District and OCWD jointly conducted the Effluent Reuse Study,which evaluated the feasibility of recycling the Sanitation District's secondary effluent from Plant No. 2 and identified projects required to achieve the final expansion of the GWRS.The GWRS final expansion effort will include implementation of projects to construct new, modified or rehabilitated facilities at Plant No. 2 to separate reclaimable flows from non-reclaimable flows;to equalize, pump, and convey secondary effluent from the Sanitation District's Plant No. 2 to the GWRS facility; and to treat the additional source water to produce 130 MGD of purified water. STRATEGIC PLAN 0 NOVEMBER 2019 m Reverse Osmosis brine generated at the GWRS Initial Expansion is currently discharged into the ocean. The 2016 Effluent Reuse Study identified alternative brine management strategies such as evaporation ponds, deep well injection, and engineered wetlands. Evaporation ponds are land intensive and are also energy intensive when combined with a brine crystallizer to remove solids from highly concentrated brine system using heat and pressure.While the areas around both the Sanitation District treatment plants have the appropriate geology for brine injection, there are concerns with contamination of drinking water aquifers, and seismic risks due to the Newport-Inglewood zones near Plant No. 2.At this time, it does not appear economically feasible to provide alternative management strategies for the brine discharge. In November 2016,the Sanitation District Board of Directors adopted the Second Amended and Restated Joint Exercise of Powers Agreement for the Development, Operation and Maintenance of the Groundwater Replenishment System and Green Acres Project, which committed the agency to continue supporting the GWRS and the Green Acres Project, and specifically,the final expansion of the GWRS.The implementation of the final phase of the expansion will be executed by multiple projects, some executed by the Sanitation District while the others executed by OCWD. Project costs related to GWRS are funded by OCWD, including$50 million reimbursement to the Sanitation District for its costs incurred to execute related projects. By supporting the GWRS Final Expansion,the Sanitation District will be able to recycle all reclaimable wastewater generated in its service area and treated at its two treatment plants, and OCWD will have sufficient water to run the GWRS facility to full capacity. Future Policy Statement The treated effluent produced from the Sanitation District's Plant Nos. 1 and 2 is a valuable resource that can help boost local water resources and reduce dependence on imported water, while reducing the effluent discharged to the ocean.The Sanitation District will continue to seek opportunities for beneficial reuse of all reclaimable wastewater collected and treated at its facilities. The Sanitation District will continue to support the completion of the final expansion of the GWRS in accordance to the adopted Second Amended and Restated Joint Exercise of Powers Agreement for the Development, Operation and Maintenance of the Groundwater Replenishment System and Green Acres Project.This includes providing secondary effluent as source water for GWRS free of charge; allowing OCWD to discharge brine via the Sanitation District's ocean outfall free of charge; leasing approximately 10 acres of land to OCWD at$1 per year for the GWRS Final Expansion project; allowing OCWD to discharge North and South Basin extraction well flows to the Sanitation District sewers; managing the design and construction efforts of the Plant No. 2 Headworks Modifications Project and the Plant Water Pump Station Replacement Project(OCWD will reimburse up to $50 million of project cost); managing and financing the construction of the Ocean Outfall Low Flow Pump Station at Plant No. 2 and the construction of Plant No. 2 primary and secondary facilities to allow segregation of non-reclaimable flows. The Sanitation District will continue to maximize the delivery of secondary effluent available to GWRS and the Green Acres Project in order to maximize full production of purified recycled water for indirect potable reuse, and industrial and irrigational uses.The Sanitation District has been operating the Steve Anderson Lift Station to divert more flows to Plant No. 1.The two agencies regularly communicate and coordinate the Sanitation District operations and construction projects that may have impacts on GWRS operation and will continue this collaboration effort. The Sanitation District has adequate flow to maximize the production of the GWRS through final expansion. Diversion of additional non-wastewater into the sewer system is unnecessary. Non- wastewater diversions create high flow risks during wet weather conditions and can introduce constituents of concern to existing water and biosolid reuse programs. mSTRATEGIC PLAN 0 NOVEMBER 2019 Initiatives to Support Progress Toward the Policy Goal • Support the completion of the final phase of the Groundwater Replenishment System and maximize reclaimable wastewater availability to the Orange County Water District. • Support Green Acres project water production to provide reclaimed water for industrial and irrigation uses. i • mil r 4 STRATEGIC PLAN■NOVEMBER 2019 m Environmental Water Quality,Stormwater Management and Urban Runoff Policy Summary Policy Statement The Orange County Sanitation District(Sanitation District) will partner with storm water permittees to accept up to ten million gallons per day of dry weather urban runoff at no charge in order to improve water quality in streams, rivers and beaches as long as the constituents within the flow do not adversely impact the Sanitation District's worker safety,treatment processes, reuse initiatives, or permit compliance.The Sanitation District facilities are subject to significant flow increases during wet weather events and are not capable of accepting stormwater flow volumes. Background The Sanitation District's wastewater collection system is designed to be wholly separate from the region's stormwater systems, also referred to as storm sewers and/or storm drains.The Sanitation District implements a system-specific Sewer System Management Plan in compliance with the California Statewide General Waste Discharge Requirements for Sanitary Sewer Systems, Water Quality Order No. 2006-0003-DWQ. In the Sanitation District's service area, most local sanitary sewer systems are owned by city municipalities and discharge into the Sanitation District-owned regional sewers. Similarly, many stormwater systems are also owned and maintained at the local level, referred to as municipal separate storm sewer systems or MS4.These publicly owned conveyances or a system of conveyances are designed to collect/convey stormwater, are not combined with sanitary sewers, and not part of the sewage treatment works. Stormwater runoff is water generated from precipitation events that flows over land or impervious surfaces including streets, parking lots, and building rooftops —this water does not return to groundwater basins, because it does not soak into the ground.This runoff accumulates pollutants from transportation, construction, industrial, and residential sources that can include trash or other solid waste, chemicals, oil, and other sediments. MS4 stormwater that is not captured for reuse,typically discharges into regional systems, most notably flood control channels (e.g.the Santa Ana River),that subsequently flow to the ocean and are regulated by the National Pollutant Discharge Elimination System (NPDES)that also regulates the Sanitation District's discharge to the ocean. Due to the design and operation of local and regional sanitary sewers,there is not system capacity to allow'wet weather' stormwater discharges to the sewer. Excessive flows into the sewer beyond its design capacity can lead to sanitary sewer overflows (also called SSOs), spills, and potential sewage backups. The Santa Ana River can provide massive storm-flow capacity at approximately 22,000 cubic feet per second (cfs) of water, and the Delhi Channel at 325 cfs, as compared to the peak wet weather flow for both the Sanitation District Plant Nos. 1 and 2 combine to less than 1,000 cfs — much of which is utilized for sanitary sewer service at all times. During'dry weather', stormwater systems collect flow from 'dry weather urban runoff activities, such as residential or industrial use, irrigation,water released from previous precipitation, among others. Most sanitary sewer systems are gravity draining, that is, most non-industrial facilities passively drain to the sewer and do not typically take action to commence discharge of wastewater.As a result, it's important that facilities are constructed in such a way that they will not drain active stormwater or urban runoff flow to the sewer, especially during rain.Additionally, stormwater best management practices (BMPs)typically dictate that the generation of contaminated stormwater should be mitigated through proper facility design including berms and grading. The Sanitation District's Wastewater Discharge Regulations Ordinance,which sets quality standards and requirements for facilities discharging to the Sanitation District, includes language to prohibit sewer users from discharging groundwater, stormwater, surface runoff, or subsurface drainage to the sewer without written authorization or a permit issued for such a purpose. In addition to the concerns related to insufficient capacity in the Sanitation District's sewer collection system,there is a concern that uncontrolled discharge to the sewer from these types of systems can introduce pollutants that may cause issues in the Sanitation District's treatment and reclamation plants, discharge to the ocean, or affect the agency's ability to recycle water or reuse biosolids.The Sanitation District's Ordinance was recently revised mSTRATEGIC PLAN 0 NOVEMBER 2019 to clarify these restrictions and include a prohibition on drainage from non-domestic surface and floor drains to address these types of uncontrolled discharges. However, given the public health and environmental protection issues that may arise from runoff- carried pollutants being transferred into the Sanitation District's coastal beaches and waters, in April 2000 the Sanitation District initiated a permitting program to assist in the economical and practical control of these pollutants during dry weather conditions. Following the Sanitation District's sponsored legislation (AB 1892),the Sanitation District's charter was amended to authorize the Board of Directors to adopt Resolution No. 00-04 establishing a dry season urban runoff policy that allowed local agencies to obtain a Dry Weather Urban Runoff Permit to discharge to the Sanitation District.Agencies could apply for this permit type where there was not an economically or practically feasible alternative (i.e. discharge to storm drain, reclamation/reuse, etc.)to discharging dry weather urban runoff to the sewer, and the discharger met other conditions including complying with the Sanitation District's Wastewater Discharge Regulations Ordinance. In September 2000, the Sanitation District modified the Dry Weather Urban Runoff Policy(Resolution No. 00-22)to cap discharges received to ten million gallons per day(MGD). Furthermore,the policy revision established the waiving of fees associated with the program until discharges exceeded four MGD, or until the policy underwent future revisions.There were a number of other modifications to the policy that added facility and compliance requirements for Dry Weather Urban Runoff permittees. The Sanitation District Board Resolution No. 01-07, adopted in March 2001, added language to the policy clarifying conditions in which the Sanitation District would and would not be indemnified against liability associated with diversion systems. Indemnification is a critical component of Dry Weather Urban Runoff agreements necessary to address the risks posed to the Sanitation District associated with water quality,flooding,trash, infrastructure damage, and other concerns. In June 2013,the Sanitation District's current policy was established when Resolution No. 13-09 was adopted.This included a revision where upon reaching a dry weather urban runoff influent rate of nine MGD,the Sanitation District will take action to reevaluate the policy. In addition to Dry Weather Urban Runoff Permits,the Sanitation District's Ordinance allows for normally prohibited wastes such as groundwater, stormwater, surface runoff, and subsurface drainage to be discharged to the Sanitation District as authorized through a Special Purpose Discharge Permit or written authorization from the Sanitation District; only when no alternate method of disposal is reasonably available or to mitigate an environmental risk or health hazard. The Dry Weather Urban Runoff and Special Purpose Discharge permit programs are intended to assist in the protection of public health and the environment by routing contaminated discharges into the Sanitation District's treatment and reclamation plants. For example,the toxic amounts of selenium in the Upper Newport Bay Watershed have resulted in regulatory requirements to remove selenium loadings from upstream creeks and channels to protect downstream aquatic life. For dry weather urban runoff discharges,the Sanitation District is able to accommodate certain waste streams that mitigate these hazards. However,the Sanitation District treatment and reclamation plants also have limitations on the loading of pollutants that can be discharged to them — particularly because traditional sewage treatment plants are not designed to remove toxic pollutants, but are designed to remove the conventional pollutants typically found in wastewater generated from normal sanitary uses.The Sanitation District's Ordinance dictates that permitted users, such as Dry Weather Urban Runoff or Special Purpose Discharge users, must comply with numeric effluent limit standards for toxic pollutants. Continuing the example from above, discharges must meet a selenium effluent limit of 3.9 milligrams per liter(mg/L), a derived value based on the compliance standard,the Sanitation District is held accountable in order to reuse biosolids. In this example,the Sanitation District may choose to issue a permit to mitigate a public health or environmental concern, but must do so in such a way as to also address the potential impact on the Sanitation District's plants and its reuse initiatives—with permit numeric limits and conditions. STRATEGIC PLAN 0 NOVEMBER 2019 m Current Situation As of June 2019,the Sanitation District maintains 21 active Dry Weather Urban Runoff Permits for diversions owned and operated by the City of Huntington Beach,the City of Newport Beach, OC Public Works, Irvine Ranch Water District, and a LLC responsible for the areas in and around Pelican Point community. For the June to December 2018 reporting period,the Sanitation District received an average of 1.03 MGD from these facilities,well below the current ten MGD policy cap and nine MGD action threshold. Since the program's inception in 2000,the Dry Weather Urban Runoff Program has treated 9.4 billion gallons of dry weather urban runoff.The success of this program is captured succinctly in reviewing the Heal the Bay 2018-2019 Beach Report Card. Heal the Bay is an environmental non-profit organization focused on coastal water and watershed quality, and reported that 92 percent of beaches in Orange County received an 'A' rating during summer dry weather conditions — some the Sanitation District-service area beaches made the report card 'honor roll' with an A+ rating. It should be noted that this overall rating is negatively impacted by south Orange County beaches that are not in the Sanitation District's service area. Both the permitted Dry Weather Urban Runoff users and the Sanitation District staff collect samples from Dry Weather Urban Runoff facilities (during dry season discharge) on a semi-annual basis to evaluate compliance with pollutant limits establish in the Sanitation District's Ordinance. Periodically, the Sanitation District works with other organizations and industries that have intentionally or unintentionally captured stormwater or runoff on-site and seek guidance on disposing of the water. The Sanitation District may authorize such a discharge request where:there is adequate capacity, wastewater meets applicable effluent discharge standards,there is no practical alternative method of disposal, and the wastewater is captured and held until it can be released to the sewer apart from a high-capacity or storm event.The Sanitation District can utilize written authorizations, special conditions on an existing wastewater discharge permit, or a Special Purpose Discharge Permit— issued for planned short-or-long-term discharges. In other instances,the Sanitation District has observed unauthorized stormwater connections to the sewer during routine inspections of facilities and worked with the dischargers to mitigate these to prevent potential overflow conditions. Special discharges described above, where acceptable through a Special Purpose Discharge Permit or written authorization, are not included in the ten MGD allowance under the Dry Weather Urban Runoff program. Key Issues for the Future Under the current policy,the Sanitation District has the capacity to accept additional dry weather urban runoff flows (up to ten MGD), however,this allotted capacity is not typically the limiting factor in increasing the volume of runoff diverted to the Sanitation District. As Dry Weather Urban Runoff diversion projects are initiated and funded at the local municipality level, capital support for such projects can be limited. Without funding and operational support from a public agency that has jurisdiction and authority over surface water runoff and wastewater,this water cannot be diverted. Diversion systems must be pumped (not gravity-fed) into the Sanitation District's collection system to ensure the necessary level of control. Furthermore, diversions cannot be implemented just anywhere. In order for the Sanitation District to accept this dry weather runoff water,the supporting sewer hydraulic capacity and infrastructure must already be in place at the specific location where the gravity diversion exists. Otherwise constructing new Sanitation District facilities to convey diverted waters would require a significant capital investment from the Sanitation District and its rate-payers. In short, acceptance of dry weather runoff must be evaluated based on the site-specific capacity of the Sanitation District's collection system, i.e.the hydraulic capacity of a specific interceptor/sewer trunkline. In addition, where the intention is to also recycle this runoff water as well as divert it from the Sanitation District's coastal beaches and waters, it must be routed to the Sanitation District's Plant No. 1 facility in Fountain Valley where it can discharge to OCWD's Groundwater Replenishment System (GWRS). At present,the Sanitation District's Plant No. 2 facility does not discharge wastewater to GWRS for recycling, and the majority of existing dry weather urban runoff facilities discharge to Plant No. 2. mSTRATEGIC PLAN 0 NOVEMBER 2019 The Sanitation District is working to divert the majority of Plant No. 2 influent wastewater to GWRS, however,the expected completion date of this project is not until 2023. It should be noted that the recycling capacity of GWRS is not unlimited and the plan to divert wastewater from Plant No. 2 is expected to provide the near maximum level of influent to GWRS.Therefore,the Sanitation District is not in a position to accept additional wastewater for recycling, and the notion that stormwater is necessary to augment GWRS influent is not a valid assumption. Given the above conditions,to expand the current programs to a larger-scale stormwater/rain-event capture and discharge program, means an investment for stormwater-authority agencies to build water storage systems in addition to existing or new diversion systems. The regional benefit for such an initiative would be the increased capture and recycling of water that would otherwise be discharged to the ocean.The potential risk to the Sanitation District and its reuse initiatives from pollutants in stormwater and runoff would be directly impacted by our agency's future ability to control these wastes—that is permit, inspect, and monitor discharging facilities, and when warranted — enact enforcement to ensure compliance with the Sanitation District's Wastewater Discharge Regulations Ordinance.To protect the Sanitation District,this means issuing stringent requirements on discharges or suspending a discharge when an existing or potential sewer user does not meet a compliance obligation. Moreover,the Sanitation District will only be able to accept stormwater and runoff discharges that can be captured and held beyond storm events, and where that water can be adequately evaluated before being released for discharge into the Sanitation District's system. The financial impact for the Sanitation District would translate to capital and operational costs where the Sanitation District is involved in the construction and maintenance of facilities to support these diversion systems. In addition, a larger-scale stormwater/rain-event capture and discharge program most certainly will require an investment in additional Sanitation District staff in the workgroup that oversees the current permitting programs. The larger question, beyond the scope of this white paper, is to evaluate at a regional level whether stormwater capture from a rain event will provide an additional source of water significant enough to offset the costs to capture this water and temporarily store it until it can be reused, including the associated infrastructure, staff, and other public resources this would require; and considering the intrinsic restrictions of the current sewer system, GWRS limitations, and the potential risks posed to the Sanitation District's existing water and biosolid reuse initiatives. Initiatives to Support Progress Toward the Policy Goal In accordance with Resolution No. 13-09,the Sanitation District intends to continue accepting up to ten million gallons per day of pumped dry weather urban runoff diversion where existing conveyance capacity exists, and the constituents of the flow will not adversely impact the Sanitation District. The Sanitation District also intends to continue working with industries, agencies, and other facilities to offer alternatives to stormwater and runoff disposal through special purpose discharge permits or other written authorization in accordance with the Sanitation District's Ordinance, where doing so does not negatively affect the Sanitation District's operation or compliance with local, state, and federal regulations, and wastewater can be held for evaluation prior to discharge. Additionally,to act as a regional partner in resolving issues associated with disposing of and reusing stormwater,the Sanitation District intends to work with local jurisdictions to determine the feasibility of regional wet weather runoff capture, storage, and use projects. • Issue dry weather urban runoff connection permits up to a total of ten million gallons per day to other service area local agencies to accept pumped dry weather urban runoff flows where existing conveyance capacity exists, and the constituents of the flow will not adversely impact the Sanitation District. STRATEGIC PLAN 0 NOVEMBER 2019 m • Continue working with industries,facilities, agencies, and local jurisdictions that have authority over stormwater or surface water runoff to determine the feasibility of regional wet weather runoff capture, storage, and use projects or offer alternatives to stormwater and runoff disposal through permits or other written authorization.The Sanitation District will promote responsible stormwater utilization and sewer protection, where doing so does not negatively affect the Sanitation District's operation or compliance with local, state, and federal regulations, and wastewater can be held for evaluation prior to discharge. 16. 4 V u V ` Ib lipV� 4 6 c. O44 4 4 y v 4 i lI mSTRATEGIC PLAN 0 NOVEMBER 2019 Wastewater Management STRATEGIC PLAN 0 NOVEMBER 2019 m Chemical Sustainability Policy Summary Policy Statement The Orange County Sanitation District(Sanitation District) has a need to use chemicals in its treatment process to improve plant performance, reduce odor and corrosion potential, and meet its regulatory requirements.These commodity chemicals are provided by outside vendors through the purchasing process. Some of these chemicals are subject to price swings due to market condition changes such as energy cost impacts, raw material cost changes, commercial competition changes, and transportation cost volitility.The Sanitation District will identify chemicals key to its operation, investigate the market risks for those chemicals and devise strategies to mitigate identified risks to availability and pricing. Background The Orange County Sanitation District(Sanitation District)treatment plants and collection system use several bulk chemicals. A sustainable supply of these chemicals is critical to maintaining an acceptable level of treatment and for ensuring compliance with all regulatory requirements.The Sanitation District spends about$13 million annually on the procurement of eight key chemicals which generally can be broken down into four categories: coagulants, odor/corrosion control, disinfection, and boiler water treatment. Boiler water treatment chemicals are low volume and readily available and will not be considered here. Coagulant Chemicals Coagulant chemicals include ferric chloride, anionic polymer, and cationic polymer.These chemicals are the workhorses of the sewage treatment process. Coagulant chemicals work to clump together organic material so it can more readily be separated from water. Ferric chloride is the first chemical added in the treatment process. It is a powerful settling agent that causes organics to clump together and settle to the bottom of primary basins. It is a double-duty chemical in that it also controls the formation of hydrogen sulfide gas,which is a major odorant, by binding to suspended sulphur compounds and causing them to settle before they can be converted by natural bacterial processes to hydrogen sulfide. Ferric chloride is an iron salt that is produced by reacting iron with hydrochloric acid. It is generally a byproduct of steel treatment, a leftover pickling agent. Ferric chloride is commonly used in the water and wastewater industries. Historically,this chemical has been the subject of a limited supplier base in Southern California.The Sanitation District has been actively splitting supply contracts to multiple vendors to ensure multiple vendors are available. On-site generation of the chemical is impractical due to the hazardous nature of the manufacturing process and acid handling,the bulk steel handing logistics, and waste products disposal. Anionic polymer works with ferric chloride to further aid in the coagulation or settling of organic compounds in the primary treatment process.These long-chain molecules are designed to be negatively charged to attract or collect positively charged ferric chloride induced organic clumps or flocculant.The use of ferric chloride and anionic polymer is called Chemically Enhanced Primary Treatment or CEPT. The Sanitation District has been using CEPT for more than thirty years. Anionic polymers are specially designed chains with many potential variants and multiple vendors. Part of the purchasing process for polymers involves polymer trials to document the efficacy of different products from different vendors to get the best cost-performance balance. Cationic polymer is generally used to thicken sludge or biosolids in centrifuges or dissolved air floatation thickeners (DAFT).These long-chained, positively charged molecules are essential to the proper operation of centrifuges and DAFT units. Part of the purchasing process for these polymers also involves polymer trials to document the efficacy of different products from different vendors to get the best cost-performance balance. It is important to note that it is entirely possible that four different cationic polymers will be used to optimize the performance of Plant No. 1 dewatering centrifuges, Plant No. 1 thickening centrifuges, Plant No. 2 dewater centrifuges, and Plant No. 2 DAFTs, because the performance can vary greatly depending on the equipment or process. Each process will have its own polymer trial to determine the cost-performance balance for each application. STRATEGIC PLAN 0 NOVEMBER 2019 Odor Control Chemicals The Sanitation District uses several chemicals in the collection system and the treatment plant to reduce the odors normally attributed to sewage and sewage treatment.These chemicals can either prevent the formation of odor causing compound, called odorants, or they can destroy odorants that already exist. Chemicals that prevent the formation of odorants include ferrous chloride, calcium nitrate, magnesium hydroxide, and caustic. Chemicals used in the collection systems tend to be more benign than chemicals used in the treatment plants due to their proximity to the public. Ferrous chloride is closely related to Ferric chloride as described above. It is a powerful settling agent that prevents the formation of hydrogen sulfide by tying up and settling sulfide compounds in the collection system. It is a preferred chemical because of its dual role, but it isn't as benign as other choices. Calcium nitrate is another choice for collection system odor control. It works in a different way. Calcium nitrate alters the biological equilibrium in sewage. Generally, bacteria that live by respirating oxygen are the most robust organisms, followed by nitrogen respirating bacteria, and finally sulfur respirating bacteria.Adding calcium nitrate to sewage creates an environment where sulfur loving bacteria don't thrive or create hydrogen sulfide. Magnesium hydroxide is a third choice for collection system odor control. It works primarily by raising the pH of sewage to a point that is not conducive for odor causing bacteria to thrive. Magnesium hydroxide is the most benign of the chemical choices as it is the main ingredient in Milk of Magnesia. All three of these chemicals are continuously fed into sewer systems at different points to consistently control the formation of odorants in the system. Where the Sanitation District doesn't have the ability to site a chemical dosing station and persistent odors are being experienced,there is the option to utilize caustic slug dosing. Caustic slug dosing involves using tanker trucks to discharge up to 6,000 gallons of sodium hydroxide into a sewer manhole structure.The very high pH has the effect of killing the bio- slime layer on sewer pipes that creates hydrogen sulfide.This treatment has an instant benefit that reduces hydrogen sulfide production for days to weeks depending on system conditions. The final major odor fighting chemical is bleach. Bleach is used in treatment plant chemical scrubbers to oxidize odorants in air scrubber units. Bleach is an effective neutralizer of hydrogen sulfide, methyl mercaptan, methyl disulfide, dimethyl disulfide, and many others. Disinfection The Sanitation District successfully discontinued disinfection of its effluent to the long outfall. This means that thousands of gallons of bleach and sodium bisulfate are no longer required to be purchased or discharged to the ocean. However, in the event of a discharge to the short outfall or river overflow, disinfection by bleach will be required. Significant on-site storage of bleach and dechlorination chemical, sodium bisulfite, is necessary for this emergency contingency. Bleach does have a shelf life of about six months.The Sanitation District rotates its disinfection supply to its odor control and plant water treatment systems to prevent product waste. Process Specific Chemicals The Sanitation District uses pure oxygen to support its activated sludge secondary treatment process for Plant No. 2. The Sanitation District previously self-generated pure oxygen using a cryogenic oxygen plant rated at 70 tons per day.This plant was removed because it was inefficient at the current average utilization of 35 tons per day and was at the end of its useful life.The Sanitation District contracts for delivery of liquid oxygen and uses a vaporization system to deliver pure gaseous oxygen to the activated sludge process. STRATEGIC PLAN 0 NOVEMBER 2019 m Chemical Supply—Purchase vs.Make The Sanitation District has relied on purchasing bulk commodity chemicals for its treatment plants and collection system.This has proven to be an effective strategy for operational flexibility and to allow concentration on core business. Operationally, the types and volume of chemicals change over time. Over time the types of polymers that are most efficient change.There is a need for more or less volume of chemicals based on sewage flow, sewage quantity, and flow splits between plants. Managing the generation of specialized chemicals using hazardous materials imposes a significant training burden on staff, increases the regulatory oversight and requirements, and increases overall risk to the organization. The Sanitation District has maintained a policy to split the volume of orders between two vendors to assure competition exists in the marketplace for ferric chloride. While the Sanitation District generally cooperates with other public agencies to pool purchasing power to secure the lowest possible cost through high volume purchasing, some specialty chemicals like ferric chloride require split orders to maintain competitive market forces. Current Situation The Sanitation District is constantly changing and improving its facilities to meet new challenges. Each of the facility changes offer new opportunities to reconsider how the Sanitation District operates its processes and how chemicals are used.The best chemical stability outcome is to cost-effectively eliminate the use of the chemical.This is the strategy behind cessation of bleach disinfection of the outfall effluent. Staff are in the process of studying the potential to operate the treatment plants differently to minimize or eliminate use of selected chemicals. Facilities like centrifuge sludge thickening provide new opportunities to adjust ferric chloride and anionic polymer usage. Opportunities for substitute chemicals will be explored to understand overall cost and efficiency savings potential.This includes iron vs. aluminum coagulant studies, anionic polymer trials, and cationic polymer trials. Staff will also reevaluate operating parameters such as in-basin sludge co-thickening, primary basin sludge blanket level parameters, as well as the greater loading of the secondary treatment systems. When optimized chemical types and dosages are confirmed, staff will review the market conditions for each important chemical.This will serve as the basis for a procurement strategy for each chemical. Future Policy Statement The Sanitation District will thoroughly understand its treatment processes,the potential modes of operation, and the benefit and cost of chemicals to improve or stabilize its process.The Sanitation District will create a list of necessary chemicals for optimal treatment operations which will consider chemical cost, chemical availability,treatment stability, energy utilization, energy creation, nuisance odor control, biosolids generation/cost, and regulatory permit compliance risks. Chemicals that are deemed most beneficial will be procured at the lowest overall cost from market providers to the extent possible.Where there are market stability concerns,the purchasing division will devise procurement strategies to mitigate procurement risks. Where procurement risk cannot be satisfactorily mitigated,technical staff will evaluate alternatives such as alternate operating methods, substitute chemical usage, or on-site generation of a chemical if feasible. Initiatives to Support Progress Toward the Policy Goal • Reduce reliance on any particular chemical or vendor and establish flexibility to utilize other chemicals/processes to accomplish the same operational objectives. • Update the Sanitation District's Chemical Sustainability Study and incorporate the results in future procurement recommendations. STRATEGIC PLAN 0 NOVEMBER 2019 Biosolids Management Policy Summary Policy Statement The Orange County Sanitation District(Sanitation District) will remain committed to a sustainable biosolids program and will beneficially reuse biosolids in accordance with Resolution No. OCSD 13-03 and the 2017 Biosolids Master Plan. Background Wastewater solids at both our treatment plants are separated,thickened, digested, and dewatered before being recycled offsite by contractors for composting and land application. Biogas created from the digesters is used to generate electricity to offset the need to purchase power from a local utility. The Sanitation District currently receives sewage sludge from the Irvine Ranch Water District at Plant No. 1, which is scheduled to cease by 2021 when Irvine Ranch Water District completes their own solids treatment facility. Prior to 2019,the Sanitation District produced an average of 800 wet tons per day(-20% solids) of Class B biosolids dewatered by belt press units. Presently, with the construction and commissioning of co- thickening sludge and dewatering centrifuges,the Sanitation District has been producing approximately 500-600 wet tons per day(25%-29% solids) with biosolids hauling cost savings of approximately $200,000-400,000/month due to the reduction in volume. The Sanitation District's biosolids program is shaped by federal, state, and local regulations and by the Sanitation District's biosolids policy(Board Resolution 13-03), our biosolids management system, and the 2017 Biosolids Master Plan (Plan).The Sanitation District manages a high quality biosolids program built on a solid policy that emphasizes the diversification of product markets for Class A and B biosolids utilized as a soil amendment for agriculture and horticulture uses.The policy also sets direction to seek opportunities in emerging markets such as biosolids-to-energy technologies to produce renewable energy in the form of biogas or used as a heating value source. These marketing principles are aligned and supported by the Plan,which provides the Sanitation District a roadmap and framework for reliable and sustainable biosolids management options while minimizing cost. In addition,the Plan sets future capital facilities improvements over a 20-year planning horizon.The Sanitation District will be implementing the Plan to develop a capital improvement project for Plant No. 2 that will result in a major change to the Sanitation District's biosolids program; namely, the construction of new mesophilic and thermophilic digesters that will generate Class A biosolids beginning in 2030.These new digesters are needed for operational resiliency against seismic events. Plant No. 1 will continue to produce Class B biosolids. The Plan evaluated end-use management alternatives for the Sanitation District's biosolids.This work supports the Sanitation District's biosolids policy and has taken into account the regulatory initiatives imposed on organic management in California as explained below.The Plan established a roadmap for the Sanitation District's commitment to beneficial use of its biosolids.The biosolids management portfolio for the Sanitation District is expected to remain similar to the overall current biosolids management end use options as it is today. Currently about half of the annual biosolids production is going to composting(CA and AZ) and half going to Class B land application in Arizona. The significant shift will begin when the Sanitation District starts reliably generating Class A biosolids at Plant No. 2. Although this is more than 10 years away,the Plan has identified early planning efforts on future end uses which include: • Emerging markets:This end use refers to either markets in which biosolids have not been tested in California at this time (e.g. land reclamation) or emerging-technology solutions (e.g. biosolids gasification, supercritical oxidation, fluidized bed combustion, cement kiln drying, pyrolysis etc.). • Soil blending:This option involves working or partnering with local soil blenders to deliver and blend Class A biosolids with soil to produce a soil amendment. STRATEGIC PLAN 0 NOVEMBER 2019 • Arizona land application: Land application in Arizona will continue to be a part of the Sanitation District's overall biosolids program and serves as a large-capacity outlet for biosolids management. • California land application: While Class A compost and granules are currently land-applied in California, land application of Class A cake is still restricted in most counties. However, it is anticipated that the implementation of California's organics diversion mandates will loosen local land applications restrictions. This programmatic framework described above has led to a reliable and sustainable biosolids management program that is designed for the beneficial use of the Sanitation District's biosolids through the utilization of diverse biosolids management options using multiple biosolids contractors, markets, and merchant facilities, while maintaining a failsafe backup capacity of at least 100 percent of the Sanitation District's daily biosolids tonnage.This forethought is necessary due to the flux of regulatory, environmental, market, and financial factors that poses potential risks to the biosolids management in California. Current Situation The legislative and regulatory landscapes in California are changing regarding organic management. For the past 15 years, direct land application of Class B biosolids has been predominately prohibited due to strict local ordinances and conditional use requirements, which preempts state recycling laws. However, in recent years there has been a need for organics diversion from landfills, healthy soils, renewable energy, and reduction of Green House Gases (GHGs), which are reflected in several important bills (laws) and initiatives that have been adopted: • AB 1826 (2014) - Mandatory Organics Recycling for Businesses. • SB 1383 (2016) - 50% organics diversion from landfill by 2020 and 75% by 2025, which includes biosolids and mandatory organics procurement(compost and biogas)for impacted jurisdiction. • SB 32 (2016) - 40% Reduction GHG below 1990 levels by 2030 • SB 100 (2018) - 50% renewable resources (i.e. anaerobic co-digestion of food waste)target by December 31, 2026, and to achieve a 60%target by December 31, 2030 • Increasing soil carbon and carbon sequestration under the Healthy Soils Initiative and Forest Carbon Plan. These measures are expanding"organic waste markets," thereby stimulating interest in siting more composting facilities and organic waste-to-energy projects and encouraging soil blending and direct land application of biosolids, opening opportunities for wastewater treatment plants such as the Sanitation District to locally manage more biosolids. Regulatory agencies such as the State Water Resource Control Board, CalRecycle, California Department of Food and Agriculture, California Air Resources Board, and California Energy Commission are developing regulations to implement the new laws. During the rule making process,the Sanitation District has been actively involved through the California Association of Sanitation Agencies (CASA) and the Southern California Alliance of POTWs (SCAP), advocating regulators to open more biosolids management options in California. In particular, the proposed regulations for SB 1383 will require jurisdictions such as cities and counties to procure recycled organics such as compost and biogas for beneficial use.This organic market will provide opportunities for regional public and/or private partnerships for biosolids management options. Although there is growing interest in California for organics management,there has also been a rising concern from the regulatory community regarding emerging contaminants such as polyfluoroalkyl substances (PFAS) and microplastics that may have some potential impact to the wastewater sector. Although to date there are no regulatory limits of these contaminants in biosolids or wastewater in California,the Sanitation District has been actively monitoring the development of the science and regulation concerning these emerging concerns. ®STRATEGIC PLAN 0 NOVEMBER 2019 Future Policy Statement As the regulatory landscape shapes to stimulate organic waste markets in California,the Sanitation District seeks to leverage its memberships with various industry associations to advocate local, state, and federal agencies to assure biosolids proposed regulations encourage the beneficial use of biosolids as a soil amendment, renewable energy, and a healthy end-use market.The Sanitation District also leverages its memberships to monitor the development of initiatives related to constituents of emerging concern that may impact the beneficial use of biosolids.The Sanitation District's leadership role in these organizations enables us to have a greater influence in key regional, state, and national issues. The Sanitation District seeks to stay abreast of developments in organic waste markets as they develop in California.The Sanitation District seeks both public and private partnerships with regional biosolids management opportunities including new innovative technology options that convert biosolids to energy and other biosolids recycling operations.This is consistent with the Sanitation District's biosolids policy and plan.To accomplish this,the Sanitation District will issue a request for information (RFI)to research and evaluate available emerging market such as biosolids-to-energy options or other biosolids recycling operations within a 200-mile radius of the Sanitation District to potentially develop a scope of work and minimum requirements for a future contract solicitation. Consistent with the Sanitation District's Plan, staff will seek to collaborate with OC Waste and Recycling (OCWR)for regional biosolids management opportunities as well as partnering with OCWR to find local solutions to meet SB 1383's organics diversion mandates, including in-county biosolids utilization, composting,food waste co-digestion, and biogas production. Initiatives to Support Progress Toward the Policy Goal • Educate and advocate with the local, state, and federal agencies to assure biosolids will continue to be safely and legally used as a soil amendment and monitor and research constituents of emerging concern such as PFAS and microplastics that may impact biosolids. • Stay abreast of new technology options to convert organics to energy and other regional biosolids recycling and renewable energy partnerships within Southern California. • Proceed with implementation of new mesophilic and thermophilic biosolids facilities at Plant No. 2 to enhance biosolids quality and marketability while improving the Sanitation District's operational resiliency against seismic events. STRATEGIC PLAN 0 NOVEMBER 2019 Constituents of Emerging Concern Policy Summary Policy Statement The Orange County Sanitation District(Sanitation District) will partner with other agencies, associations, and institutions to support the use of sound science to inform policy and regulatory decisions on constituents of emerging concern (CECs) at the federal, state, and regional levels. Staff will obtain and maintain current knowledge on CECs under regulatory consideration, including occurrence, analytical methods, regulations, and treatment to support the Sanitation District's mission. Background CECs also referred to as Constituents or Contaminants of Emerging Concern are pollutants that may or may not be subject to regulatory requirements or statutes yet pose a risk to public health and/or the environment.The Sanitation District is a recipient of CECs that are discharged along with domestic and residential wastewater; discharges from industrial, commercial, and other governmental facilities; and tributary discharging jurisdictions.The concept of CECs evolves over time and often the Sanitation District and other entities must acknowledge and understand their impacts to address the effects posed by each CEC. For more than 50 years,the Sanitation District has adopted and enforced standards and requirements to protect the public health and safety, the environment, and the Sanitation District's workers and facilities,while collecting and treating wastewater. Initially the primary concern to the Sanitation District was conventional pollutants,those that originate from normal sanitary use and can be addressed by conventional wastewater treatment. With the 1972 amendment to the Clean Water Act, and as required by the Code of Federal Regulations,the Sanitation District implemented a mandated pretreatment program to control discharges containing toxic pollutants at their sources through permitting, enforcement, inspection, and sampling.The Sanitation District's Pretreatment Program promulgates the Sanitation District's Wastewater Discharge Regulations Ordinance (Wastewater Ordinance), which governs discharges to the sewer through various types of permits.The Wastewater Ordinance also includes numeric limits, referred to as Local Limits,that control the quality of non-domestic discharges to the sewer.These Local Limits are the result of a technical evaluation and comprehensive sampling and analysis effort, required under the Sanitation District's permit issued by the state to discharge to the ocean —the National Pollutant Discharge Elimination System (NPDES) Permit. The Sanitation District's current NPDES Permit requires evaluation and monitoring of CECs.The Regional Water Quality Control Board (RWQCB) and EPA required the Sanitation District to study and report on certain newer CECs in the Sanitation District's effluent and the receiving waters.The CEC study had to include the following categories and specified a set of particular constituents in each category: Hormones (8), Industrial Endocrine Disrupting Compounds (7), Pharmaceuticals and Personal Care Products (13), and Flame Retardants (9). Since 2014, California's State Water Resource Control Board has been updating its Recycled Water Policy and has identified CECs under consideration for projects that conduct surface spreading of recycled water, including the Groundwater Replenishment System (GWRS). In addition,to meet the Sanitation District's obligations to provide a high level of service for biosolids reuse and water reclamation through GWRS,the Sanitation District must evaluate and monitor CECs that affect these initiatives. Although the Sanitation District has been involved with water reclamation with the Orange County Water District(OCWD) since the mid-1970's,the Sanitation District's mission changed significantly in the years leading up to 2008 when the Groundwater Replenishment System (GWRS) was commissioned. GWRS compelled the Sanitation District to consider impacts to drinking water limits and Notification and Response Levels, which are typically much lower than the standards in place for a wastewater treatment plant. For several critical constituents, OCWD and the Sanitation District established a Level of Service commitments.The Sanitation District and OCWD established a response plan to follow when a constituent becomes a concern to either agency. Where the source can be identified,the plan organizes responsive actions from the Sanitation District and OCWD for industrial and commercial facilities. Domestic and residential sources are typically addressed by way of educational outreach to the public. STRATEGIC PLAN 0 NOVEMBER 2019 To determine the constituents that impact the Sanitation District's operations and reuse initiatives, the Sanitation District interacts with federal, state, and local agencies and monitors their regulatory and legislative efforts. Sometimes the job is straightforward, because the federal, state, or local agency focuses on a specific CEC chemical which yields a concentrated effort; however, sometimes, the effort can be interpretative.This requires a comprehensive,well-established program and experienced subject matter experts to identify the CECs that impact the Sanitation District.The Sanitation District must then evaluate the sources and decide what methods will be employed to control the discharges, if necessary. Current Situation With newer equipment and techniques,federal, state, and local government agencies are detecting constituents at very low concentrations in the drinking water.This has resulted in agencies studying more constituents and requesting NPDES Permit holders, such as the Sanitation District,to monitor and report CECs detected in the influent and effluent. However,wastewater is a much more complex matrix than drinking water, so reproducible low-level analytical methods are much more difficult to develop and implement for wastewater than drinking water. The Sanitation District will also be required to develop new methods for addressing some of the CECs primarily discharged from residential communities or are present in the existing drinking water supply. The Sanitation District typically attempts to address such discharges through education and outreach while working with other agencies. Some CECs require the Sanitation District and other agencies to sponsor legislation and regulation development or to comment on a particular subject to protect the agency's interests. For example, the Sanitation District has advocated for minimizing or eliminating the use of specific CECs in manufacturing or consumer use to the California Department of Toxic Substances Control. To achieve its mission, the Sanitation District will need to continue supporting a variety of regulatory and legislative efforts. Future Policy Statement If source control, education and outreach, or legislative and regulatory efforts are not successful,the Sanitation District may be required to implement a technological or operational process change/ investmentto address a CEC. The Sanitation District must align its resources to continue managing CECs throughout the service area and treatment process in order to comply with the Sanitation District's existing regulatory requirements and sustain beneficial reuse of biosolids.The Sanitation District shall acquire and maintain a high level of subject matter expertise and engagement across the wastewater,water,water reuse, air quality, ocean monitoring, and biosolids sectors to monitor the threats posed by upstream sources to its system;to continue to work with other agencies and professional organizations to develop robust analytical methods; and to evaluate routinely the need to establish sound policies, local limits, or other regulations and standards based on new local, state, and federal regulations to protect public health and the environment.The Sanitation District is required to continue implementing its established response plan by promoting effective source control and treatment, while also preparing for newer CECs and regulatory obligations.The Sanitation District will continue to work to understand the operational and financial impacts of current and future CECs by monitoring developing regulations and legislation and actively engaging regulatory, environmental, academic, industry, and community stakeholders. Two families of chemicals, PFAS and PFOA, have been identified as CEC's with a probability of impacting water and biosolids reuse.Attached is OCWD's August 2019 PFOA and PFAS Fact Sheet.This is an example of a CEC where the Sanitation District must be engaged helping to explore the science and shape future legislation and regulation to help create practical solutions to real world concerns. STRATEGIC PLAN 0 NOVEMBER 2019 Initiatives to Support Progress Toward the Policy Goal • The Sanitation District will continue to actively engage water and wastewater stakeholders to stay abreast of the scientific progress and any potential operational and financial impacts of CECs and provide timely briefings to the Sanitation District's Management Team and Board to facilitate informed decision making. • The Sanitation District will continue to develop capacity to detect, quantify, and characterize CECs throughout the service area and treatment process in order to promote treatment effectiveness and the communication of credible risks. • The Sanitation District will proactively research laboratory techniques and other scientific research to understand the real and potential impact of CECs, like PFAS and PFOA, on the reuse of water and biosolids.The Sanitation District will use science-based knowledge to help shape legislation and regulation to protect the public health and environment. Ind 1 ) ` P 7 f mSTRATEGIC PLAN■NOVEMBER 2019 STRATEGIC PLAN■NOVEMBER 2019 Resilient Staffing Policy Summary Policy Statement The Orange County Sanitation District(Sanitation District) will attract and retain high-quality talent to support its mission and continue to be an industry leader. It will safeguard leadership continuity and support effective performance of the organization by proactively monitoring the changing work environment and requirements to ensure development programs are relevant and build a skilled bench of readily available successors for key leadership and mission-critical positions. Background At the Sanitation District, employees are the organization's most valuable resource. With over 600 dedicated employees whose collective efforts make OCSD an industry leader,the Sanitation District continues to receive national awards and recognition.That is why, OCSD has committed to invest in its employees, resulting in a highly skilled and educated workforce carrying out the mission of protecting public health and the environment. The Sanitation District has a diverse workforce and a wide range of expertise with approximately 70 percent of positions requiring a degree, certification, and/or license. Occupations on-site include scientists, engineers, environmental and regulatory specialists, operators, mechanics, construction inspectors, as well as professionals in public affairs,finance, IT, safety and human resources. To cultivate a committed and engaged workforce in a competitive economy, OCSD must promote initiatives to attract and retain talent and prepare staff for successful careers. Strategic succession management initiatives have been developed and adopted that support the design and implementation of comprehensive workforce planning and development tools accompanied by activities that facilitate the improvement of workforce capability, adaptability, efficiency, and accountability. Strategic workforce planning empowers management to project the loss of knowledge and experience caused by retirement and attrition and utilizes a variety of methods to ensure that the Sanitation District has adequate access to talent internally and externally through the recruitment and selection process. The Sanitation District has a competitive recruitment process that ensures we hire the best person for the job based on qualifications and merit. Human Resources utilizes an objective multi-hurdle approach to hiring which includes Human Resources review and recommendation, subject matter expert application screening, assessment centers, panel interviews (both for technical skills and fit), skills testing, background checks, and reference checks. Programs that have proven effective in attracting, retaining and developing highly skilled staff for key positions, include: • Vocational/Professional Student Internship Programs Students from the Water Utility Science Program at Santiago Canyon College, and Los Angeles Trade Technical College work 28 hours a week and rotate through five technical trades for 53 weeks in our Operations and Maintenance Department. We started the program in 2010 with four positions and have grown to offer ten positions for each fiscal year. Furthermore, 14 of the program participants have been hired full-time since the program inception.The Sanitation District is piloting the program with other technical colleges in Southern California,to include Cypress College. OCSD offers student and vocational internships, as well as job shadowing and externships. The Sanitation District's Professional Student Internship Program offers students an opportunity to work at the professional ranks while attending college full-time for a two-year maximum duration. OCSD partners with Cal State Fullerton, Long Beach, Cal Poly Pomona and UC Irvine, among others. STRATEGIC PLAN 0 NOVEMBER 2019 • Employee Development Program In addition to legally mandated training,the Sanitation District provides training and development opportunities for the purpose of increasing job knowledge and to maximize skill sets in employees' current positions and to prepare them for future mission-critical positions. Comprehensive training programs include technical training through industry-specific associations or groups, local schools, and professionals as well as informal on the job training. Employees are encouraged to obtain job- related training necessary to keep OCSD current with recent industry best practices and developments in their respective fields of expertise and can receive Development Pay in select categories that the Sanitation District deems mission-critical. As 70 percent of OCSD's positions require a degree, certificate and/or license,the Sanitation District also promotes professional development through its tuition and certification reimbursement programs for courses completed toward obtaining an associate's, bachelor's or master's degree at accredited colleges, universities, or other institutions or industry specific certifications that are applicable to the industry. • Workforce Vulnerability Assessments Each year,the Sanitation District management conducts an evaluation of their respective departments and identifies key and vulnerable positions based on three criteria: criticality, retention, and difficulty to fill.Vulnerability assessments provide a broader view into the areas of the agency that could potentially be facing a high risk in turnover and are essential to operations. Management is tasked with identifying positions based on the criteria above,then making recommendations on the level of action that is required, complete with proposed action plans. Human Resources staff works closely with management to facilitate workforce vulnerability assessments to develop current and future staffing plans. It is essential that the Sanitation District continues to focus its efforts on prioritizing staffing needs. • Talent Readiness Assessments The process includes departmental leadership evaluating staff and identifying key employee talent, as well as possible development efforts. Feeder positions are identified, and talent pools are developed between employees and management that align with agency goals and builds the talent pipeline. • Building Leaders and Skills for Tomorrow (BLAST) Program In 2011,the Sanitation District began a comprehensive leadership development program to supplement the technical training courses, and includes job shadowing, mentoring,web-based and instructor-led training on soft skills and leadership development.The goal of this development program is to ensure OCSD is building leaders at all levels. Development opportunities are offered to address the potential loss of talent and feed into the Succession Management and Employee Development programs, primarily focusing on soft skills training.The leadership development components include a public sector leadership academy with Cal State Fullerton, and a supervisory training program through Brandman University. The Sanitation District partnered with University of California, Irvine, California State University, Long Beach, and California Polytechnic University at Pomona,which provided students an opportunity to job shadow Human Resources and Engineering staff to gain insight into the profession, employment in the public sector and the wastewater industry.The Sanitation District employees also serve on Advisory Councils that weigh in on course curriculum at various schools, both at the high school and college level, across Southern California. Throughout the agency,we have several employees who are active members of various professional associations, serve on a Board, or volunteer in various capacities within the industry.The Sanitation District staff is regularly asked to present and teach others about resource recovery. Recruiters attend job fairs, and work closely with universities, professional organizations, and serve on advisory committees. STRATEGIC PLAN 0 NOVEMBER 2019 Education and workforce investment programs represent the most important preparation we can accomplish today to safeguard the agency's future for tomorrow. Finding an adequate pool of applicants and retaining qualified workers is increasingly difficult,which we anticipate will continue on into the future. Retirements are disrupting employment within our industry and changes in technology have made work more complex. Current Situation Academics studying the labor force attribute labor shortages to workforce demographics. Depending on the source data,the timelines defining the start/end time of these groups may vary but generally— Baby Boomers are those born between 46-64,followed by Gen Xers 65-81, and lastly Millennials from 82-00. Close to half of staff or 49 percent fall into the "Gen Xers" category,followed by 32 percent made up of"Baby Boomers" and "Millennials" make up 19 percent of our employee population.The Sanitation District is currently facing a potential loss of close to half of its workforce — about 45 percent of employees, primarily from the Baby Boomers group, and some Gen Xers.This represents a potential loss of about 271 people to retirement alone and does not account for other forms of turnover. Hence the need to be proactive and strategic in CICSD's approach to maintain its staffing levels and ensure continuity of operations. Currently, the majority of CICSD's executives are eligible for retirement. Managers, our next level of leadership, closely follow with 45 percent of them eligible to retire now, and that number increases to 90 percent in five years.The Sanitation District has a little more stability in the trades and professional occupations with retirement eligibility at 53 percent in the next five years. CICSD has a lot of long-term employees with vast knowledge in their respective areas of expertise. Some employees have been a part of the CICSD family for over 35 years; and at last count,ten years was the average years of service. Looking at CICSD's total attrition over the last five years,we have lost 3,025 years of knowledge and experience by 132 individuals leaving the agency since 2014. In 2010,the Sanitation District proactively implemented a second retirement benefit formula ("classic open plan") ahead of the Public Employee Pension Reform Act,which offered candidates moving from other public sector agencies to CICSD with a retirement benefit of 2.43 percent at 65, with zero employer paid member contribution. Based on the Sanitation District's classic open retirement plan, CICSD is unable to compete for experienced talent from surrounding municipalities, who offer a retirement benefit of 2.5 percent or 2.7 percent at 55 and pay a portion of the employees' contribution. Since implementation of the classic open plan in 2010, only 22 percent of new hires come from other public sector agencies.The Sanitation District has had experience with public sector candidates withdrawing from the process or declining job offers once they learn of the impact to the retirement benefit formula. The vast majority of new hires are coming from private sector and have no public sector experience requiring additional training. Given the legal restrictions which bind the Sanitation District to the classic open formula, it is critical CICSD focus its efforts on retaining current staff, attracting qualified candidates, and investing heavily into developing and growing employees' knowledge, skills and abilities for the future,to address any potential talent shortages. Future Policy Statement Human Resources will continue to implement strategic initiatives that ensure workforce capabilities match the work required to meet the Sanitation District's mission and levels of service. Staff is dedicated to proactively monitoring the changing work environment and requirements to implement programs now that address future vulnerabilities.Assessments of changes in business needs,workforce composition, and legal requirements are necessary to ensure resilient staffing. Initiatives to Support Progress Toward the Policy Goal • Maintain and enhance current effective development programs that are in place to provide the direction to identify, develop and select the next generation of prepared, capable and engaged leaders, which include: • Vocational/Professional Student Internship Programs . 1 STRATEGIC PLAN 0 NOVEMBER 2019 • Employee Development Program • Workforce Vulnerability Assessments • Talent Readiness Assessments • Building Leaders and Skills for Tomorrow (BLAST) Program • Strengthening Operator Training Programs • Continue cyclical Classification & Compensation studies to ensure job classifications accurately depict the work being performed,to set compensation levels accordingly, and stay abreast of market benefit and salary data. Prior to the next scheduled Classification & Compensation study, Human Resources will work with the Board of Directors and meet and confer with the unions to review selected survey agencies based on recognized classification and compensation standards and the job market in which we compete. i� lam inll1 --'Mo rM, wagZIP t c' str; ti STRATEGIC PLAN■NOVEMBER 2019 Safety and Physical Security Policy Summary Policy Statement The Orange County Sanitation District(Sanitation District) will ensure the safety and security of employees, contractors and visitors through standard practices, policies, and procedures that support a safe and secure environment, provide an appropriate level of security and safeguard OCSD's property and physical assets. Background In California, employers must furnish employees with a place of employment free from recognized hazards that cause death or serious physical harm,that is compliant with all legal requirements and aligns with industry best practices.The safety and wellness of the public and employees is our number one priority. OCSD is committed to identifying all hazards through inspection and providing engineering controls,job specific safety training, and personal protective equipment. Programs that have proved effective in ensuring the safety and wellness of OCSD's workforce, visitors and contractors include: Safety Assessments and Engineering Controls In 2014, OCSD conducted a Facility-Wide Safety Assessment Project(SP-145-1)to identify process equipment design and configuration issues that may impact worker safety, and compliance with regulations.The main purpose of this effort was to enhance worker safety and ensure compliance with safety codes. At the same time, safety improvements allow for reliable and efficient operation, so that our facilities can meet regulatory and process demands,while providing cost effective operation.All the Project SP-145-1 recommendations to be implemented by OCSD have either been addressed by Maintenance or have been incorporated into the Safety Improvement Project(J-126). Emergency Management The Sanitation District must be prepared to control risks to the organization, and routinely recognize, evaluate, and prepare for emergencies.An emergency can include a major explosion, fire, verified bomb threat, civil disorder, active shooter situation, or uncontrolled materials release which interrupts OCSD's ability to provide safe and environmentally responsible wastewater treatment.The Sanitations District's protocol to control and respond to emergencies is contained within the Integrated Emergency Response Plan (IERP). The IERP identifies and assesses hazards regarding emergency events which OCSD may be confronted with and contains policies, plans, and procedures for preparing and responding to emergencies.The Sanitation District's emergency response organization, called the Incident Command System (ICS), is activated when an emergency condition cannot be effectively responded to under routine operations. Once the immediate emergency has been controlled,then OCSD must resume normal operations. In the event of a prolonged emergency state,the return to normal operations is guided by a Continuity of Operations Plan (COOP). In May 2018, a COOP was completed with all divisions contributing to its development. Business continuity planning is an ongoing process for OCSD with plans being updated as information changes. The Sanitation District collaborates with local agencies to ensure available resources are identified and engaged in the event of an emergency. OCSD has partnered with local agencies in the areas of emergency response for evacuation drills and resource sharing. .�STRATEGIC PLAN 0 NOVEMBER 2019 • The Sanitation District participated in the 2019 Orange Crush Regional Emergency Preparedness and Training Exercise in January 2019.This county-wide exercise used a scenario of a magnitude 7.8 earthquake strike along the San Andreas Fault. A full Emergency Operations Center activation occurred for this functional exercise and gave the Sanitation District the opportunity to test the Integrated Emergency Response Plan. • The Orange County Sheriff's Department and the Orange County Health Care Agency established a Joint Information Center at Plant No. 2 on May 13-14, 2019 to host an enforcement event in Talbert Park. In addition, the operation was overseen by three federal judges who were present to ensure the rights of all citizens were not violated by law enforcement or The Health Care Agency. Officials utilized Plant No. 2 contractor gates for points of entry. • The Sanitation District is a member and funding agency of the Water Emergency Response of Orange County (WEROC), which is an organization that is administered by the Municipal Water District of Orange County (MWDOC). It supports and manages countywide emergency preparedness, planning, response and recovery efforts among Orange County water and wastewater utilities. Security The Department of Homeland Security has designated 16 critical infrastructure sectors,which includes water and wastewater systems. Wastewater systems are vulnerable to a variety of attacks, including acts of terrorism, contamination with deadly agents; physical attacks, such as the release of toxic gaseous chemicals, and cyberattacks. In addition, the Department of Homeland Security indicates that the average time it takes for a critical incident to take place is up to 12 minutes while the average police response time can be up to 11 minutes and that time could increase should there be a natural disaster. Additional security concerns include physical violence,vandalism,theft, and trespassers.With approximately 100 acres at each site, 600 employees, contractors, and members of the public on site for tours and meetings, it is essential to maintain a security force that can respond to security threats promptly. The Sanitation District contracts with a security firm that supplies four armed and five unarmed guards to provide round the clock security monitoring of over 80 cameras, monitoring gate access, and patrolling the perimeter at both plants. Current Situation The Risk Management division has been given the responsibility and an adequate budget to assess and control the safety, security, and health risks that employees, contractors, and guests may be exposed to from OCSD operations.Assessment and control of risks is achieved collaboratively between Risk Management staff and internal stakeholders. Risk Management, managers, and staff collaborate to develop written procedures (e.g., policies)that are used for controlling and eliminating hazards at OCSD; thus, ensuring compliance with occupational health and safety standards and laws. Safety As the health and safety of employees, contractors and visitors is the number one priority,the Sanitation District strives to achieve safety excellence.This is exemplified by our pursuit of the California Voluntary Protection Program (Cal/VPP).The Cal/VPP is a program created by Cal/OSHA to recognize organizations who have implemented safety and health programs that effectively prevent and control occupational hazards. A Cal/VPP workplace is expected to continually improve its safety program; which means a safe workplace for all. A reduction in injuries and illness has been documented at sites that have committed to the VPP approach. Cal/VPP is recognized as a higher level of protection for the workplace,for this reason, OCSD is pursuing this designation. In preparation for application to the Cal/VPP program,the Sanitation District conducted a Cal/VPP readiness assessment in January 2019 and developed an implementation strategy.The assessment STRATEGIC PLAN■NOVEMBER 2019 .� included interviews with various OCSD subject matter experts and discussions with employees during facility tours. OCSD procedures and records were reviewed, and limited visual inspection of work locations and facilities was conducted.The assessment considered basic Cal/OSHA regulatory compliance and additional best management practices that are expected to be implemented in VPP certified workplaces. Based on the results of the VPP assessment, OCSD is working toward applying for VPP before the end of calendar year 2019.The timing coincides with the implementation of most of the Safety Improvement Project(1-126),which are critical for success in our VPP pursuit. This Safety Improvement Project(J-126) is progressing on-schedule. Of the eleven J-126 projects, two have been completed, seven are in the construction phase, and two are pending contractor award. It is important to note that interim measures have been taken to ensure worker safety at the locations identified for safety improvements. Workers are not exposed to hazards while projects are completed. Eliminating hazards through engineering projects is critical, along with a positive safety culture. In order to assess the safety culture at OCSD, a survey was conducted from February to April 2019.The results of this survey indicated employees believe the safety culture is improving, desired an increase in communication on safety issues, and wanted less online and more hands-on customized safety training. Emergency Management The Sanitation District partners with local agencies to ensure available resources are identified and engaged in the event of an emergency. Collaborations currently scheduled include: • In conjunction with WEROC, OCSD participated in the development of the Orange County Water and Wastewater Hazard Mitigation Plan (Plan)which will be submitted for approval to the State.The Plan provides a framework for participating water and wastewater utilities to plan for natural and man-made hazards in Orange County.The Sanitation District is an active participant in the Plan, and developed a hazard mitigation plan, which is Annex C of the Plan.The resources and information within the Plan will allow OCSD, and participating jurisdictions to identify and prioritize future mitigation projects, meet the requirements of federal assistance programs and grant applications, and encourage coordination and collaboration in meeting mitigation goals. • On July 27, 2019,the Sanitation District partnered with the Fountain Valley Police Department Explorers during OCSD's Open House event.The Police Explorers assisted Human Resources and Risk Management with crowd and traffic control.Their assistance was beneficial in the management of public during this important event. Security The designation of wastewater systems as critical infrastructure by the Department of Homeland Security requires OCSD to be diligent in protecting people and property from security breaches. OCSD seeks to continually improve the security program. On June 7, 2019, OCSD issued a Request for Proposal (RFP)for Security Services,which included a potential expansion of security services for OCSD's new Headquarters Complex. As part of the RFP evaluation, OCSD will review procedural and technical enhancements/innovations that may improve the existing program. In addition, OCSD has established a Security Committee, which includes stakeholders from a cross- section of the organization,to collect input and assess physical and cybersecurity concerns and suggestions. Responsibilities of the committee include, but are not limited to, development of a physical and cybersecurity plan, reviewing orders and policies, reviewing incident reports, and planning drills. The first meeting of the committee was held on June 6, 2019. Future Policy Statement Risk Management has and will continue to implement strategic initiatives that will ensure the safety, health, and security of its workforce, and proactively plan for emergencies to ensure continuity of operations. Staff is dedicated to proactively monitoring the changing work environment and .�STRATEGIC PLAN 0 NOVEMBER 2019 requirements to implement programs now that address future vulnerabilities.Assessments of changes in business needs, plant processes and legal requirements are necessary to ensure a safe and secure work environment.The results of improvement will be measured using leading metric indicators and reported to the workforce to foster employee engagement. Initiatives to Support Progress Toward the Policy Goal Safety • Complete outstanding safety projects, improvements, and corrective actions to apply and obtain Cal/ OSHA Voluntary Protection Program (VPP) status; and continue to foster a culture where employees are accountable for their safety as well as the safety of others. Emergency Management • Support facility and countywide emergency preparedness, response, and recovery efforts by partnering with entities, such as,the Water Emergency Response Organization of Orange County (WEROC), Orange County Sherriff Department, and local fire departments to plan and continue to conduct disaster preparedness training and exercises. Security • Continually identify and assess vulnerabilities and implement solutions through the Security Committee and third-party assessments. Prevent/mitigate security breaches using physical security systems such as video monitoring, access control, and armed security patrols.

FROM: James D. Herberg, General Manager Originator: Kathy Millea, Director of Engineering SUBJECT: BAY BRIDGE PUMP STATION FORCE MAIN ISOLATION VALVE REPLACEMENT, PROJECT NO. FRC-0013 GENERAL MANAGER'S RECOMMENDATION RECOMMENDATION: A. Ratify Approval of an Emergency Repair Service Contract to Charles King Company for Bay Bridge Pump Station Force Main Isolation Valve Replacement, Project No. FRC-0013, for an amount not to exceed $289,585; and B. Approve a contingency of $144,793 (50%). BACKGROUND The Orange County Sanitation District (OC San) owns and operates pump stations and a force main network along Pacific Coast Highway in Newport Beach. The Bay Bridge Pump Station, Rocky Point Pump Station, and the Lido Pump Station all pump into, and pressurize, this two-pipe force main system. Each pump station has an isolation valve to each force main pipe to allow separation of the internal pump station systems from the other pump stations. This is necessary to isolate suction and discharge headers and common flow elements to be maintained or repaired. These pump station force main isolation valves are also necessary to install temporary bypass pumping systems at the individual pump stations and to stop flow to either force main pipe if it were compromised in some way. The Bay Bridge Pump Station was originally constructed in 1965 and is near the end of its useful life. Bay Bridge Pump Station Replacement, Project No. 5-67, is in design and is scheduled to replace the pump station by 2027. The pump isolation valves at the Bay Bridge Pump Station are in urgent need of replacement. Replacement cannot wait until the new pump station is completed. In November 2020, the Board awarded a contract for Bay Bridge Pump Station Valve Replacement, Project No. FRC-0002, to replace the valves within the pump station. The work includes bypass pumping to take the pump station out of service which cannot proceed until working pump station force main isolation valves are installed. Orange County Sanitation District Page 1 of 3 Printed on 8/18/2021 powered by LegistarTM File #: 2021-1819 Agenda Date: 8/25/2021 Agenda Item No: 9. RELEVANT STANDARDS • Achieve less than 2.1 sewer spills per 100 miles • Comply with OC San Policy (Ordinance No. OC SAN-56, Article 5 - Public Works Projects, Section 5.03A - Exceptions, Emergencies and Calamities) PROBLEM In the course of executing the Bay Bridge Pump Station Valve Replacement, Project No. FRC-0002, staff has become aware that the two pump station force main isolation valves at the Bay Bridge Pump Station cannot provide positive isolation between the pump station and the force mains. This means that OC San is unable to maintain or repair important equipment in the pump station and will also not be able to isolate flow to either force main in the event of a leak or damage to the pipe system. Replacement of the force main isolation valves is complex and carries significant risk. PROPOSED SOLUTION Given the criticality of the pump station isolation valves, the failure of these valves poses a clear and imminent danger to essential public services, in this case, wastewater conveyance. On July 28, 2021, the General Manager declared an emergency to replace the force main isolation valves so that the force mains can be isolated and to allow completion of Bay Bridge Pump Station Valve Replacement, Project No. FRC-0002, before the coming wet weather season. Staff recommended the approval of an Emergency Repair Service Contract to replace the pump station force main isolation valves. This work will involve pump station shutdowns and bypass pumping that involves a significant risk of a sewage spill without proper planning, contingency measures, and a contractor with a proven ability to perform such complex, time-sensitive work. Following the July 28, 2021 emergency declaration, the General Manager issued a purchase order to Charles King Company (Charles King) to perform initial work under the emergency provisions in OC San's Purchasing Ordinance No. OC SAN-56. On August 5, 2021, the General Manager informed the Board Chair that the emergency repair by Charles King would exceed $100,000. The Chair concurred with proceeding with the emergency repairs. Since the emergency work exceeds $100,000, ratification of the Service Contract by the Board of Directors is required in accordance with OC San's Purchasing Ordinance. The proposed upper limit is based on the initial work plan prepared by Charles King. As plans are prepared in more detail, the cost could change significantly. For this reason, staff is requesting an unusually high contingency to quickly address any needs that arise. TIMING CONCERNS Any delay in completing the pump station force main valve replacements will likely prevent the individual pump isolation valves from being replaced until after the wet weather season. Given the Orange County Sanitation District Page 2 of 3 Printed on 8/18/2021 powered by LegistarTM File #: 2021-1819 Agenda Date: 8/25/2021 Agenda Item No: 9. poor condition of the interior pump station valves needed to isolate and service pumps, there is a significant risk that the pump station might not be able to handle peak wet weather flows. RAMIFICATIONS OF NOT TAKING ACTION Without this emergency repair, the contract for Bay Bridge Pump Station Valve Replacement, Project No. FRC-0002, would need to be cancelled, and the work combined with the pump station force main valve replacement into a new public works contract. With procurement and award timeframes, not being able to do the work during the wet season, and the City of Newport Beach not allowing lane closures during the busy summer season, the work would likely need to be delayed until September 2022. PRIOR COMMITTEE/BOARD ACTIONS N/A ADDITIONAL INFORMATION OC San contacted two firms with successful experience performing urgent, high-risk collection system projects: Jamison Engineering and Charles King. Jamison Engineering was not able to start work until September, so staff engaged Charles King to start work. The initial authorization included preparation of a detailed work plan and excavation of the piping near the force main isolation valves. They were also asked to find replacement valves that could be delivered in a short period of time. CEQA The project is exempt from CEQA under the Class 1 categorical exemptions set forth in California Code of Regulations sections 15301. A Notice of Exemption will be filed with the OC Clerk-Recorder after OC San's Board of Directors approval of the Emergency Repair Service Contract. FINANCIAL CONSIDERATIONS This request complies with the authority levels of OC San's Purchasing Ordinance. This recommendation would be funded under the Repairs and Maintenance line item for the Operations and Maintenance Department (Budget Update Fiscal Year 2021-2022, Page 45), and the available funding is sufficient for this action.

FROM: James D. Herberg, General Manager Originator: Kathy Millea, Director of Engineering SUBJECT: BAY BRIDGE PUMP STATION VALVE REPLACEMENT, PROJECT NO. FRC-0002 GENERAL MANAGER'S RECOMMENDATION RECOMMENDATION: Approve a contingency increase of $269,100 (45%) to the service contract with Innovative Construction Solutions for Bay Bridge Pump Station Valve Replacement, Project No. FRC-0002, Specification No. S-2020-119213D, for a total contingency of $328,900 (55%). BACKGROUND The Orange County Sanitation District (OC San) owns and operates pump stations and a force main network along Pacific Coast Highway in Newport Beach. The Bay Bridge Pump Station, Rocky Point Pump Station, and the Lido Pump Station all pump into, and pressurize, this two-pipe force main system. Each pump station has an isolation valve to each force main pipe to allow separation of the internal pump station systems from the other pump stations. This is necessary to be able to isolate the suction and discharge headers and common flow elements so they may be maintained or repaired. These pump station isolation valves are also necessary to install temporary bypass pumping systems around any individual pump station. Within each pump station, each pump has its own suction and discharge isolation valves so individual pumps and check valves can be maintained or repaired while the rest of the station is in service. When a pump isolation valve fails, its associated pump can no longer be taken out of service for repair with the overall pump station in service. The Bay Bridge Pump Station was originally constructed in 1965 and is near the end of its useful life. Bay Bridge Pump Station Replacement, Project No. 5-67, is in design and is scheduled to replace the pump station by 2027. The pump isolation valves at the Bay Bridge Pump Station are in urgent need of replacement. The replacement on these pump isolation valves cannot wait until the new pump station is completed. In November 2020, Board awarded a $598,000 Contract to Innovative Construction Solutions for Bay Bridge Pump Station Valve Replacement, Project No. FRC-0002, to replace these valves. The work includes bypass pumping to take the pump station out of service to replace the individual pump isolation valves. Orange County Sanitation District Page 1 of 3 Printed on 8/18/2021 powered by LegistarTM File #: 2021-1820 Agenda Date: 8/25/2021 Agenda Item No: 10. RELEVANT STANDARDS • Ensure the public's money is wisely spent • Maintain a proactive asset management program • Achieve less than 2.1 sewer spills per 100 miles PROBLEM Replacement of the individual pump suction and discharge isolation valves depends on functioning pump station isolation valves to the force mains which cross under Newport Bay. When the contractor attempted to start the work, the force main isolation valves would not prevent back flow from the force mains to the pump station caused by the bypass pumps. The contractor was not able to begin the contract work within the pump station and was directed to demobilize until a solution could be found. On July 28, the General Manager declared an emergency to quickly replace the force main isolation valves so that this contract work can be restarted in the fall to be completed before the coming wet weather season. Although the original contract scope of work has not been significantly changed, the contractor has incurred compensable costs to mobilize and demobilize. The mobilization and demobilization costs are much more significant than a typical construction contract and include significant traffic control measures (extended lane closure on Pacific Coast Highway), bypass pumping setup, and staging to perform the mechanical work. These costs will exceed the Board-authorized 10 percent contingency. Necessary maintenance work on the individual pumps and flow control devices in the pump station is being deferred until these isolation valves are replaced. PROPOSED SOLUTION Increase the contingency to cover the costs for demobilization and remobilization, and to address other problems that may arise during the pump station valve replacement work. TIMING CONCERNS Without the additional contingency, the contractor will not be able to complete the valve replacements before this coming wet weather season. Without the new valves to isolate the pumps for necessary maintenance, there is a significant risk that the pump station might not be able to handle peak storm flows. RAMIFICATIONS OF NOT TAKING ACTION Without the additional contingency, staff would need to cancel the remaining work to cover the costs the contractor has already incurred. A new contract would have to be solicited, and that new contract would not be available in time for the wet season. Without the new valves, OC San staff would be unable to isolate and service the pumps if they become inoperable. As of mid-August, two pumps are leaking badly, but cannot be serviced because the isolation valves are not functional.

PRIOR COMMITTEE/BOARD ACTIONS November 2020 - Awarded a construction contract to Innovative Construction Solutions for Bay Bridge Pump Station Valve Replacement, Project No. FRC-0002, for a total amount not to exceed $598,000, and approved a contingency of$59,800 (10%).

Vaccination rates in the US have slowed, and infection rates have recently increased but remain well below their peak.Thus far, US-approved vaccines have shown to be effective against COVID-19 as well as more aggressive variants.As such, we remain optimistic about the continued reopening of the US economy. Meanwhile, although some pandemic- related fiscal relief is starting to phase out, President Biden and a group of bipartisan senators have agreed to an overall framework for an infrastructure plan. Though the details have not been finalized or approved by Congress, the negotiations signal that more fiscal stimulus is likely on the horizon. Meanwhile, the Federal Reserve continues to signal that it will look past the near-term uptick in inflation to facilitate continued improvement in the labor market. While we believe financial market volatility is likely to increase in the second half of the year, we anticipate that gross domestic product(GDP) will continue to grow at an above-trend pace. The Federal Open Market Committee(FOMC) kept monetary policy unchanged in June.The fed funds target rate remains in the range of 0.0%to 0.25%, and the Fed continues to purchase $80 billion of Treasuries per month, and $40 billion of agency mortgage-backed securities per month. The Fed has started to discuss the idea of reducing its asset purchases at some point, but that decision remains uncertain. FOMC members' updated economic projections also suggest that the Fed may start to raise interest rates in 2023,versus the previous estimate of 2024.Overall, monetary policy remains highly accommodative for now, but the Fed seems to be inching toward a path of policy normalization. We believe the Fed will proceed with caution, particularly given the high number of people who remain unemployed and continued uncertainty about the pandemic and impact of COVID-19 variants. While about 55% of people in the U.S. have received at least one dose of a COVID-19 vaccine, less than a quarter of the world population has received at least one dose. Should the U.S. economy remain on its current trajectory, and global vaccination rates improve meaningfully, we believe there is a high probability that the Fed will begin tapering its asset purchases during the first half of next year. The yield curve flattened in June. We believe multiple factors influenced Treasury rates in June, including market technicals, dollar strengthening, uneven global vaccination rates, and a more modest forecast for U.S. infrastructure spending than initially expected. Nevertheless, we believe longer-term rates have room to move higher this year and we believe the Treasury yield curve is poised to steepen in the second half of the year. 1 CHANDLER ASSET cill MANAGEMENT The treasury yield curve is steeper on a year-over-year basis. The 3-month T-bill yield was about nine basis points lower, while the 2-year Treasury yield was about ten basis points higher,and the 10-Year Treasury yield was about 81 basis points higher,year-over-year, as of June month-end.The Fed has signaled plans to keep the front end of the Treasury yield curve anchored near zero until 2023. We believe longer-term rates still have room to move higher this year. Consumer Prices The Consumer Price Index (CPI) was up 5.0% year-over-year in May versus up 4.2% in April. Core CPI (CPI less food and energy) was up 3.8%year-over-year in May,versus up 3.0% in April.The Personal Consumption Expenditures (PCE) index was up 3.9%year-over-year in May,versus up 3.6%year-over-year in April. Core PCE was up 3.4%year-over-year in May, versus up 3.1% year-over-year in April. Current inflation readings are running well above the Fed's longer-run target of around 2.0%, though many of the factors are expected to be temporary. Retail Sales On a year-over-year basis, retail sales were up 28.1% in May versus up 53.4% in April. The year-over-year gains are distorted by the drop-off in spending and activity at the early stage of the pandemic last year. On a month-over-month basis, retail sales declined 1.3% in May, following a 0.9% increase in April. Retail sales have been somewhat uneven due to the timing of fiscal stimulus and economic reopening. Overall, we believe consumer spending remains healthy and consistent with an ongoing recovery in economic activity. Labor Market Job growth was stronger than expected in June. U.S. nonfarm payrolls increased by 850,000, versus the consensus forecast of 720,000. May payrolls were also revised up by 24,000 to 583,000. On a trailing 3-month and 6-month basis, payrolls increased by an average of 567,000 and 543,000 per month, respectively, which is indicative of a steady recovery in the labor market.The leisure and hospitality sectors continue to drive the job gains in June and increased by 343,000. Government payrolls also posted a solid increase of 188,000 in June.The labor participation rate was unchanged at 61.6% in June.The unemployment rate ticked higher to 5.9%in June from 5.8% in May.The U-6 underemployment rate, which includes those who are marginally attached to the labor force and employed part time for economic reasons, declined to 9.8% in June from 10.2%in May.The index of aggregate private weekly payrolls was up 2.8% in June from February 2020, suggesting a solid increase in aggregate wages. Housing Starts Total housing starts rose 3.6% in May to an annual pace of 1,572,000. Single-family starts rose 4.2% in May while multi- family starts were up 2.4%. On a year-over-year basis, housing starts were up 50.3% in May, due in part to the steep decline in activity during the early stage of the pandemic last year. 2 CHANDLER ASSET C11% MANAGEMENT TREASURY YIELDS 6/30/2021 3/31/2021 CHANGE 3 Month 0.04 0.02 0.02 2 Year 0.25 0.16 0.09 3 Year 0.46 0.35 0.11 5 Year 0.89 0.94 (0.05) 7 Year 1.24 1.42 (0.18) 10 Year 1.47 1.74 (0.27) 30 Year 2.09 2.41 (0.32) Economy Is Poised for Continued Above-Trend Growth ECONOMIC INDICATOR Current Release Prior Release One Year Ago Trade Balance (71.24)$BIn MAY 21 (69.07)$Bln APR 21 (54.92)$BIn MAY 20 Gross Domestic Product 6.40%MAR 21 4.30%DEC 20 (5.00%)MAR 20 Unemployment Rate 5.90%JUN 21 5.80%MAY 21 11.10%JUN 20 Prime Rate 3.2S%JUN 21 3.2S%MAY 21 3.2S%JUN 20 Commodity Research Bureau Index 213.39JUN 21 205.70 MAY 21 137.97 JUN 20 Oil (West Texas Int.) $73.47 JUN 21 $66.32 MAY 21 $39.27 JUN 20 Consumer Price Index(y/o/y) 5.00%MAY 21 4.20%APR 21 0.10%MAY 20 Producer Price Index(y/o/y) 8.70%MAY 21 9.SO%APR 21 (3.20%)MAY 20 Dollar/Euro 1.19 JUN 21 1.22 MAY 21 1.12 JUN 20 Source:Bloomberg 3 CHANDLER ASSET cill MANAGEMENT Performance Attribution Long-Term Portfolio The OC Sanitation Long-Term Portfolio generated a positive quarterly total return of 0.19% compared to the 0.20%total return of the ICE Bank of America Merrill Lynch 1-5 Year US Corporate and Government AAA-A Index. During the quarter, the term structure of the Treasury curve adjusted with shorter maturity yields moving higher and longer maturity yields moving lower. The Chandler team believes one of the primary catalysts for the change in interest rates was the Federal Reserve's technical adjustment to the Interest on Excess Reserves (IOER) rate, increasing the IOER target to 0.15% from 0.10%, and also adjusting the Federal Reserve's reverse repo rate higher to 0.05% from 0.00%. The change in IOER and the Reverse Repo rate served to put a floor on very short maturity Treasury yields which led to benchmark two year and three year rates moving higher, while longer term rates were more stable, grinding lower by a total of 5 basis points at the five year maturity point. The unorthodox change to the term structure did not enable the portfolios more barbelled portfolio structure, relative to the benchmark,to generate above benchmark returns. Multiple securities were purchased in the Treasury,Commercial Paper,Certificate of Deposit,Asset Backed and Corporate sectors of the portfolio allocation. The purchased securities ranged in maturity from July 2021 to June 2026. Several securities were sold and matured to facilitate the new holdings in the portfolio. $30 million was contributed to the portfolio in April 2021. The sector allocation was relatively stable. Notably the Treasury and Agency allocations each moved lower by 2.2% and 3.0% respectively, offset by modest increases in the Supranational, Corporate, Asset Backed, Commercial Paper and Negotiable Certificate of Deposit sectors. The duration of the portfolio was stable on a quarter over quarter basis, remaining at 2.55. The Chandler team will continue to keep the overall duration of the portfolio close to the benchmark in coming quarters. Liquid Portfolio Multiple purchases were made in the Treasury, Commercial Paper, Certificate of Deposit, and Corporate sectors to keep the portfolio allocation consistent with Chandlertargets and forecasted cash flow needs. The purchased securities ranged in maturity from October 2021 to May 2022. Several securities matured during the reporting period to fund the new holdings in the portfolio and provide for the cash needs at the end of the quarter. On a net basis $42 million in cash was added to the portfolio, a $72 million contribution in April and a $30 million withdrawal in June. The sector allocation changed moderately during the quarter. Notably the Treasury allocation was reduced by 9.8%to 78.8% of the portfolio, partially offset by increases of 3.8% in Commercial Paper and 2.4% in Certificates of Deposit, to 3.8% and 3.9% of the portfolio, respectively. The duration of the portfolio increased moderately to 0.35 compared to the prior quarter's 0.30. The Chandler team will continue to look for opportunities to lengthen the duration of the portfolio consistent with the upcoming cash flow needs of OC Sanitation. 4 CHANDLER ASSET MANAGEMENT Economic Outlook The timeline on the global economic recovery extended in the 2nd quarter as the coronavirus delta variant spread and Covid containment measures negatively impacted the reopening theme in multiple developed market economies. The pace of Covid vaccinations in the U.S.also slowed with both the South and Midwest having disproportionately lower levels of vaccination compared to the rest of the country which could introduce additional risks to the economic recovery later in the year. Given the high level of vaccine availability in the U.S., the risk of a domestic government shutdown of the economy remains very low in Chandler's view. Risk assets continued to perform, although the rate of change slowed and some of the laggards from the prior quarter recovered.Arguablythe most impactful market movement during the quarter was the flattening of the US Treasury yield curve, most pronounced in the latter half of June. Short maturity rates moved higher, and longer maturity rates contracted, which also contributed to some of the broad sector repricing in the equity market as the reopening economic narrative continues to evolve. Economic data was solid during the quarter with the three-month moving average of non-farm payrolls at 567k and the unemployment rate down to 5.9%as of June 2021. Supply bottlenecks continue to permeate in multiple sectors, but the Chandler team expects the shortages to dissipate on multiple fronts, particularly in the 4th quarter as extended unemployment benefits expire and children returning to school should increase the availability of sidelined workers. Both the ISM Manufacturing and Services Indices remain robust at 60.6 and 60.1, respectively, however both are marginally lowerthan the prior month readings indicating the possibility peakgrowth will be in 2Q 2021. Market participants continue to closely follow developments on inflation, and whether the Federal Reserve's 'transitory' forecast will come to fruition. Annualized Core CPI came in at 4.5% in June and the Core PCE Deflator, the Federal Reserves preferred inflation metric, at 3.4% annualized in May. Chandler's base case is inflation will remain elevated over the summer months and then stabilize, albeit at higher levels than the pre-pandemic experience.The risk case is inflation accelerates further late in the year and into 2022, if supply bottlenecks persist and the availability of workers does not remedy some of the supply/demand imbalances. Congressional negotiations on the proposed infrastructure bill continue,and Chandler expects legislation to move forward later in the year.The Federal Reserve surprised market participants at the June FOMC meeting with the Interest on Excess Reserves (IOER) rate increasing by 0.05%,to 0.15%, and the Federal Reserve Reverse Repo rate increasing to 0.05%from the previous 0.00%. Policymakers appear to have been concerned about the 'ill functioning' money market sector and increasing the IOER and Reverse Repo rate helped to mitigate the possibility of negative interest rates in short maturity Treasury notes. The change in policy accelerated the flattening of the Treasury curve as the yield on the two year and three year Treasury notes moved higher after the IOER adjustment. Several factors were at play in supporting the move lower in longer maturity Treasury yields, however the Chandler team believes the dominant influence is linked to the Federal Reserve's Flexible Average Inflation Targeting (FAIT) regime. The Federal Reserve established the FAIT regime in 2020 to better allow for an inflation overshoot to make up for the time periods when inflation was below the 2%objective. In Chandler's view an adherence to FAIT policy would lead to the Federal Reserve maintaining accommodative policy for longer, promoting a steeper Treasury yield curve, and implying when the Federal Reserve ultimately adjusted rates the magnitude of the change would be greater than recent cycles due to higher realized inflation (a higher terminal fed funds rate). In essence the Fed's updated policy is'outcome based' as opposed to 'forecast based', allowing for an overshoot of inflation metrics. Recent commentary from multiple Federal Reserve Governors seems to be questioning the Fed's committee to the FAIT framework.The Chandler team believes Fed Chair Powell, Fed Vice Chair Clarida and New York Fed President Williams remain committed to the FAIT framework, and do not believe the Federal Reserve will tighten monetary policy prematurely and forecast the steepening bias in the Treasury curve to reassert itself later this year. 5 CHANDLER ASSET C11% MANAGEMENT Strategy Strategy highlights for the Long-Term Portfolio in coming months: • Remain focused on structuring the overall term structure and asset allocation of the portfolio consistent with a growing economy and patient Federal Reserve from a monetary policy standpoint. o Look to add Corporate exposure further out the curve with attractive relative value. o Continue to avoid the Agency sector where a lack of issuance in 2021 has led to unattractive valuations— consider the sector a source of funds when executing duration extension swaps in other products. o Opportunistically add to the Supranational sector when spreads offer a reasonable concession to the Agency sector and are consistent with the swaps curve. • Chandler models continue to highlight the four year maturity point as being attractively priced—look to add spread product in this portion of the term structure where applicable. Strategy highlights for the Liquidity Portfolio in coming months: • Continue to ladder the Treasury and Agency exposure to coincide with forecasted liquidity needs. Taking into account the current zero rate policy by the Federal Reserve, look at immunize cash flow needs with Commercial Paper where applicable. • Opportunistically add longer duration (i.e., close to one year) in the Corporate and Negotiable CD portion of the allocation to take advantage of the more attractive valuation from both a maturity and spread perspective compared to the Treasury sector. • Maintain a dedicated exposure to the Treasury sector on an ongoing basis to ensure ample transactional liquidity in the event of an unexpected cash flow need. 6 CHANDLER cill � ASSET MANAGEMENT Compliance Issues Orange County Sanitation District Long Term Assets managed by Dandier Asset Management or¢in full complicrim with store low arid with the investment policy Category Standard Comment U.S.Treasuries 10%minimum;5 years max maturity Complies- 2m6 max per agency of the U.S.Govemment,which,does not provide the full faith and credit of the U.S.government;5 years max maturity;Securtes,obligations, Federal Agencies participations,or other instruments of,or issued by,or fully guaranteed as to principal and interest by the US Govemmern,a federal agency,or a USGovernment- Complies sponsored enterprise "AA"rated or better by a NRSRO;30%max;5 years max maturity;U.S.dollar denominated senior unsecured unsubordinated obligations issued or unconditionally Supranational Obligations guaranteed by the International Bank for Reconstruction and Development("IBRD"),the International Finance Corporation("Ik")orthe Inter-American Development Complies Bank("IADB") Municipal Securities "A"rated or higher by a NRSRO;or as otherwise approved by the Board of Directors;Taxable or tax-exempt municipal bonds issued by any of the 50 states;3036 max;

Greg Allen,CEO and Chief Research Officer Callan Institute V @CallanLLC ® Callan Definitions Risk/Reward Statistics The risk statistics used in this report examine performance characteristics of a manager or a portfolio relative to a benchmark (market indicator) which assumes to represent overall movements in the asset class being considered. The main unit of analysis is the excess return, which is the portfolio return minus the return on a risk free asset (3 month T-Bill). Alpha measures a portfolio's return in excess of the market return adjusted for risk. It is a measure of the manager's contribution to performance with reference to security selection. A positive alpha indicates that a portfolio was positively rewarded for the residual risk which was taken for that level of market exposure. Beta measures the sensitivity of rates of portfolio returns to movements in the market index. A portfolio's beta measures the expected change in return per 1% change in the return on the market. If a beta of a portfolio is 1.5, a 1 percent increase in the return on the market will result, on average, in a 1.5 percent increase in the return on the portfolio. The converse would also be true. Downside Risk stems from the desire to differentiate between "good risk" (upside volatility) and "bad risk" (downside volatility). Whereas standard deviation punishes both upside and downside volatility, downside risk measures only the standard deviation of returns below the target. Returns above the target are assigned a deviation of zero. Both the frequency and magnitude of underperformance affect the amount of downside risk. Excess Return Ratio is a measure of risk adjusted relative return. This ratio captures the amount of active management performance (value added relative to an index) per unit of active management risk (tracking error against the index.) It is calculated by dividing the manager's annualized cumulative excess return relative to the index by the standard deviation of the individual quarterly excess returns. The Excess Return Ratio can be interpreted as the manager's active risk/reward tradeoff for diverging from the index when the index is mandated to be the"riskless" market position. Information Ratio measures the manager's market risk-adjusted excess return per unit of residual risk relative to a benchmark. It is computed by dividing alpha by the residual risk over a given time period. Assuming all other factors being equal, managers with lower residual risk achieve higher values in the information ratio. Managers with higher information ratios will add value relative to the benchmark more reliably and consistently. R-Squared indicates the extent to which the variability of the portfolio returns are explained by market action. It can also be thought of as measuring the diversification relative to the appropriate benchmark. An r-squared value of .75 indicates that 75% of the fluctuation in a portfolio return is explained by market action. An r-squared of 1.0 indicates that a portfolio's returns are entirely related to the market and it is not influenced by other factors. An r-squared of zero indicates that no relationship exists between the portfolio's return and the market. Relative Standard Deviation is a simple measure of a manager's risk (volatility) relative to a benchmark. It is calculated by dividing the manager's standard deviation of returns by the benchmark's standard deviation of returns. A relative standard deviation of 1.20, for example, means the manager has exhibited 20% more risk than the benchmark over that time period. A ratio of .80 would imply 20% less risk. This ratio is especially useful when analyzing the risk of investment grade fixed-income products where actual historical durations are not available. By using this relative risk measure over rolling time periods one can illustrate the "implied" historical duration patterns of the portfolio versus the benchmark. Residual Portfolio Risk is the unsystematic risk of a fund, the portion of the total risk unique to the fund (manager) itself and not related to the overall market. This reflects the "bets" which the manager places in that particular asset market. These bets may reflect emphasis in particular sectors, maturities (for bonds), or other issue specific factors which the manager considers a good investment opportunity. Diversification of the portfolio will reduce or eliminate the residual risk of that portfolio. Callan 27 Risk/Reward Statistics Rising Declining Periods refer to the sub-asset class cycles vis-a-vis the broader asset class. This is determined by evaluating the cumulative relative sub-asset class index performance to that of the broader asset class index. For example, to determine the Growth Style cycle, the S&P 500 Growth Index (sub-asset class) performance is compared to that of the S&P 500 Index(broader asset class). Sharpe Ratio is a commonly used measure of risk-adjusted return. It is calculated by subtracting the "risk-free" return (usually 3 Month Treasury Bill) from the portfolio return and dividing the resulting "excess return" by the portfolio's risk level (standard deviation). The result is a measure of return gained per unit of risk taken. Sortino Ratio is a downside risk-adjusted measure of value-added. It measures excess return over a benchmark divided by downside risk. The natural appeal is that it identifies value-added per unit of truly bad risk. The danger of interpretation, however, lies in these two areas: (1)the statistical significance of the denominator, and (2) its reliance on the persistence of skewness in return distributions. Standard Deviation is a statistical measure of portfolio risk. It reflects the average deviation of the observations from their sample mean. Standard deviation is used as an estimate of risk since it measures how wide the range of returns typically is. The wider the typical range of returns, the higher the standard deviation of returns, and the higher the portfolio risk. If returns are normally distributed (ie. has a bell shaped curve distribution) then approximately 2/3 of the returns would occur within plus or minus one standard deviation from the sample mean. Total Portfolio Risk is a measure of the volatility of the quarterly excess returns of an asset. Total risk is composed of two measures of risk: market (non-diversifiable or systematic) risk and residual (diversifiable or unsystematic) risk. The purpose of portfolio diversification is to reduce the residual risk of the portfolio. Tracking Error is a statistical measure of a portfolio's risk relative to an index. It reflects the standard deviation of a portfolio's individual quarterly or monthly returns from the index's returns. Typically, the lower the Tracking Error, the more "index-like"the portfolio. Treynor Ratio represents the portfolio's average excess return over a specified period divided by the beta relative to its benchmark over that same period. This measure reflects the reward over the risk-free rate relative to the systematic risk assumed. Note: Alpha, Total Risk, and Residual Risk are annualized. Callan 28 Fixed Income Portfolio Characteristics All Portfolio Characteristics are derived by first calculating the characteristics for each security, and then calculating the market value weighted average of these values for the portfolio. Allocation by Sector- Sector allocation is one of the tools which managers often use to add value without impacting the duration of the portfolio. The sector weights exhibit can be used to contrast a portfolio's weights with those of the index to identify any significant sector bets. Average Coupon - The average coupon is the market value weighted average coupon of all securities in the portfolio. The total portfolio coupon payments per year are divided by the total portfolio par value. Average Moody's Rating for Total Portfolio- A measure of the credit quality as determined by the individual security ratings. The ratings for each security, from Moody's Investor Service, are compiled into a composite rating for the whole portfolio. Quality symbols range from Aaa+ (highest investment quality- lowest credit risk) to C (lowest investment quality- highest credit risk). Average Option Adjusted (Effective) Convexity- Convexity is a measure of the portfolio's exposure to interest rate risk. It is a measure of how much the duration of the portfolio will change given a change in interest rates. Generally, securities with negative convexities are considered to be risky in that changes in interest rates will result in disadvantageous changes in duration. When a security's duration changes it indicates that the stream of expected future cash-flows has changed, generally having a significant impact on the value of the security. The option adjusted convexity for each security in the portfolio is calculated using models developed by Lehman Brothers and Salomon Brothers which determine the expected stream of cash-flows for the security based on various interest rate scenarios. Expected cash-flows take into account any put or call options embedded in the security, any expected sinking-fund paydowns or any expected mortgage principal prepayments. Average Option Adjusted (Effective) Duration- Duration is one measure of the portfolio's exposure to interest rate risk. Generally, the higher a portfolio's duration, the more that its value will change in response to interest rate changes. The option adjusted duration for each security in the portfolio is calculated using models developed by Lehman Brothers and Salomon Brothers which determine the expected stream of cash-flows for the security based on various interest rate scenarios. Expected cash-flows take into account any put or call options embedded in the security, any expected sinking-fund paydowns or any expected mortgage principal prepayments. Average Price-The average price is equal to the portfolio market value divided by the number of securities in the portfolio. Portfolios with an average price above par will tend to generate more current income than those with an average price below pa r. Average Years to Expected Maturity- This is a measure of the market-value-weighted average of the years to expected maturity across all of the securities in the portfolio. Expected years to maturity takes into account any put or call options embedded in the security, any expected sinking-fund paydowns or any expected mortgage principal prepayments. Average Years to Stated Maturity- The average years to stated maturity is the market value weighted average time to stated maturity for all securities in the portfolio. This measure does not take into account imbedded options, sinking fund paydowns, or prepayments. Current Yield-The current yield is the current annual income generated by the total portfolio market value. It is equal to the total portfolio coupon payments per year divided by the current total portfolio market value. Callan 29 Fixed Income Portfolio Characteristics Duration Dispersion - Duration dispersion is the market-value weighted standard deviation of the portfolio's individual security durations around the total portfolio duration. The higher the dispersion, the more variable the security durations relative to the total portfolio duration ("barbellness"), and the smaller the dispersion, the more concentrated the holdings' durations around the overall portfolio's ("bulletness"). The purpose of this statistic is to gauge the "bulletness" or "barbellness"of a portfolio relative to its total duration and to that of its benchmark index. Effective Yield-The effective yield is the actual total annualized return that would be realized if all securities in the portfolio were held to their expected maturities. Effective yield is calculated as the internal rate of return, using the current market value and all expected future interest and principal cash flows. This measure incorporates sinking fund paydowns, expected mortgage principal prepayments, and the exercise of any"in-the-money" imbedded put or call options. Weighted Average Life- The weighted average life of a security is the weighted average time to payment of all remaining principal. It is calculated by multiplying each expected future principal payment amount by the time left to the payment. This amount is then divided by the total amount of principal remaining. Weighted average life is commonly used as a measure of the investment life for pass-through security types for comparison to non-pass-through securities.

The recovery has been fueled by robust fiscal spending, accommodative monetary policy, and a swift vaccine rollout. These factors are beginning to moderate but should continue to provide tailwinds for the economy in the coming quarters. Vaccinations have slowed down, and infection rates in the US have recently ticked up but remain well below their peak. Some pandemic-related fiscal relief is starting to phase out, but an infrastructure spending plan is likely on the horizon. Meanwhile, the Federal Reserve remains accommodative and continues to signal that it will look past any near-term uptick in inflation to facilitate continued improvement in the labor market. Estimates for US GDP growth remain strong. The current Bloomberg consensus estimate for 2021 and 2022 US GDP growth are 6.6% and 4.2%, respectively. • The Federal Open Market Committee (FOMC) kept monetary policy unchanged at its June meeting. The fed funds target rate remains in the range of 0.0%to 0.25%, and the Fed continues to purchase $80 billion of Treasuries per month, and $40 billion of agency mortgage-backed securities per month. The Fed has started to discuss the idea of reducing its asset purchases at some point, but that decision remains uncertain. FOMC members' updated economic projections also suggest that the Fed may start to raise interest rates in 2023, versus the previous estimate of 2024, as the economy may be on track to reach their employment and inflation goals at a faster than expected pace. Overall, monetary policy remains highly accommodative for now, but the Fed seems to be inching toward a path of policy normalization. We anticipate the Fed will remain on the sidelines over the near-term, but we believe the probability that the Fed will begin tapering its asset purchases during the first half of next year has increased. The yield curve flattened in June. We believe multiple factors influenced Treasury rates in the month, including market technicals, dollar strengthening, uneven global vaccination rates, and a more modest forecast for U.S. infrastructure spending than initially expected. The Treasury yield curve has continued to flatten in July, driven by a decline in longer- term rates. Nevertheless, we believe longer-term rates are poised to move higher this year and we believe the Treasury yield curve is likely to steepen into year-end. 3 C11% Will $5.5 Trillion Stimulus Propel Growth and Inflation?

The Fed lowered the fed funds target rate to a range of 0.0%-0.25% and continues to purchase Treasury and agency mortgage-backed securities to support smooth market functioning. Last year, policymakers reinstated the Commercial Paper Funding Facility and Money Market Mutual Fund Liquidity Facility. The Fed also established the Primary Market Corporate Credit Facility, Secondary Market Corporate Credit Facility, Term Asset-Backed Securities Loan Facility, Paycheck Protection Program Liquidity Facility, Main Street Lending Facility, and Municipal Liquidity Facility. The Fed has also provided short-term funding through large-scale repo operations and lowered the reserve requirement for depository institutions. Notably, many of the Fed's lending facilities expired at the end of 2020, including the Fed's corporate credit, asset-backed securities, municipal lending, and Main Street Lending programs. In June 2021, the Fed announced plans to gradually unwind its corporate credit facility and expects to sell the full portfolio by year-end. 5 Q11 Employment Nonfarm Payroll (000's) Unemployment Rate 6,000 24.0% 1%♦ 21000 20.0% 1 / 1 / 1 % o -2 000 o / 16.0% —` -6,000 , j �♦� t " S 12.0% •• -10,000 °C ••��• g 8.0% - 0 -14,000 �"��------- -18,000 Non-farm Payroll(000's) 4.0% --- Underemployment Rate(U6) -3 month average(000's) Unemployment Rate (U3) -221000 - 0.0% ✓4 SP pP � ✓4 SO 10 47 ✓4 ✓4 SP pP ✓4 SO 6 ' ✓4 hI? p19 c19 dr110 7�O ,b)0 c,110 dr�1 ��1 �19 p19 c19 dr�0 ��0 p-)o coo Source:US Department of Labor Source:US Department of Labor Job growth was stronger than expected in June.

On a trailing 3-month and 6-month basis, payrolls increased by an average of 567,000 and 543,000 per month, respectively, which is indicative of a steady recovery in the labor market. The leisure and hospitality sectors continue to drive the job gains in June and increased by 343,000. Government payrolls also posted a solid increase of 188,000 in June. The labor participation rate was unchanged at 61.6% in June and is 1.7% lower than the pre-pandemic level. The employment-population ratio was also unchanged in the month at 58.0% and is 3.1% below the pre-pandemic level. The unemployment rate ticked higher to 5.9% in June from 5.8% in May and remains well above the pre-pandemic low of 3.5% in February 2020. The U-6 underemployment rate, which includes those who are marginally attached to the laborforce and employed part time for economic reasons, declined to 9.8% in June from 10.2% in May (versus 7.0% in February 2020). The index of aggregate private weekly payrolls was up 2.8% in June from February 2020, suggesting a solid increase in aggregate wages. 6 Q11 Initial Claims for Unemployment Initial Claims For Unemployment April 16, 2021-July 16,2021 6,000 Initial Jobless Claims (Continuing Claims 5,000 I 4,000 3,653 3,680 3,640 3,738 3,611 3,769 3,484 I 3,517 3,528 3,412 3,367 I I J I 3,265 3,236 ■1-- 3,000 W 7 O t E 2,000 1,000 566 590 507 478 444 405 388 374 418 416 368 386 368 419 OQ, OQ/ OQ, OT Off/ Off/ Off/ 06, 06, 06, 06, 0) O) O)/ J'0��,7 0,��1 1 �1��1 ����1 0 ,11��,Z 1 �S��,Z 0 /09��,7 ,76��1 Source:US Department of Labor In the most recent week, the number of initial jobless claims was 419,000 versus 368,000 in the prior week.

Fed policymakers have reiterated that they believe most of those factors will be temporary. 8 Ci„ IConsumer Retail Sales YOY % Change Consumer Confidence 60.0% 140 50.0% 130 40.0% 30.0% 120 s 20.0% - J 110 10.0% x 0 0.0% = 100 -10.0% 90 -20.0% - Li -30.0% 80 ✓4 sP pP ✓4 sP pP ✓4 ✓� sP pP � ��, so p� �19 p1.9 c19 drip �l0 a�0 c�0 0,, ��1 "'l9 p19 c19 dr'p IiI)O Source:US Department of Commerce Source:The Conference Board On a year-over-year basis, retail sales were up 18.0% in June versus up 27.6% in May.

On a month-over-month basis, retail sales increased 0.6% in June (exceeding expectations), following a 1.7% decline in May. Retail sales have been somewhat uneven on a monthly basis due to the timing of fiscal stimulus and economic reopening. Overall, we believe ongoing fiscal support, an improving labor market, and further progress on vaccinations should continue to support consumer spending. The Consumer Confidence index jumped to 127.3 in June from 120.0 in May, reflecting a strong view of current conditions and a more upbeat outlook. 9 cA„ IEconomic Activity Leading Economic Indicators (LEI) Chicago Fed National Activity Index (CFNAI) 4.0% 6.00 2 0% 4.00 2.00 0 0.0% bb r_ M s W 0.00 -2.0% s -- -2.00 0 0 -4.0% "' -4.00 -6.0% -6.00 -8.0% -8.00 ✓4h 1 SPb1 1 �a'' ✓�''�� SPp� c� �a'' ✓�''�� ✓47 Z SPpZ O�'cZ �ar� ✓4�� SPa� O�°c� � ✓�'�� 9 9 9 )O O O O �1 1 9 9 9 O O O O I 1 Source:The Conference Board Source:Federal Reserve Bank of Chicago The Conference Board's Leading Economic Index (LEI) increased 0.7% month-over-month in June (slightly below expectations), following a 1.2% increase in May.

More complete descriptions of Moody's and Standard & Poor's ratings are included in the following pages. Quality/Grade Moody's Standard & Poor's Fitch Best Quality Aaa AAA AAA High Quality Aal AA+ AA+ Aa2 AA AA Aa3 AA- AA- Upper Medium Grade Al A+ A+ A2 A A A3 A- A- Medium Grade Baal BBB+ BBB+ Baa2 BBB BBB Baa3 BBB- BBB1 Moody's - Investment Grade "Aaa" - Bonds rated Aaa are judged to be of the best quality. They carry the smallest degree of investment risk. Interest payments are protected by a large or by an exceptionally stable margin and principal is secure. While the various protective elements are likely to change, such changes as can be visualized are most unlikely to impair the fundamentally strong position of such issues. "Aa" - Bonds which are rated Aa are judged to be of high quality by all standards. Together with the Aaa group they comprise what are generally known as high grade bonds. They are rated lower than the best bonds because margins of protection may not be as large as in Aaa securities or fluctuation of protective elements may be of greater amplitude or there may be other elements present which make the long-term risks appear somewhat larger than in Aaa securities. "A" - Bonds which are rated A possess many favorable investment attributes and are to be considered as upper medium grade obligations. Factors giving security to principal and interest are considered adequate, but elements may be present which suggest a susceptibility to impairment sometime in the future. "Baa" - Bonds which are rated Baa are considered as medium grade obligations; i.e., they are neither highly protected nor poorly secured. Interest payments and principal security appear adequate for the present but certain protective elements may be lacking or may be characteristically unreliable over any great length of time. Such bonds lack outstanding investment characteristics and in fact have speculative characteristics as well. Bonds in the Aa, A, and Baa are also assigned "V, "2", or "Y based on the strength of the issue within each category. Accordingly, "Al" would be the strongest group of A securities and "AY would be the weakest A securities. Ba, B, Caa, Ca, and C - Bonds that possess one of these ratings provide questionable protection of interest and principal ("Ba" indicates some speculative elements; "B" indicates a general lack of characteristics of desirable investment; "Caa" represents a poor standing; "Ca" represents obligations which are speculative in a high degree; and "C" represents the lowest rated class of bonds). "Caa", "Ca" and "C" bonds may be in default. Standard and Poor's-Investment Grade AAA- Debt rated "AAA" has the highest rating assigned by S&P. Capacity to pay interest and repay principal Is extremely strong. AA - Debt rated "AX has a very strong capacity to pay interest and repay principal and differs from the highest rated issues only in small degree. A - Debt rated "A" has a strong capacity to pay interest and repay principal although it is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than debt in higher rated categories. BBB - Debt rated "BBB" is regarded as having an adequate capacity to pay interest and repay principal. Whereas it normally exhibits adequate protection parameters, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity to pay interest and repay principal for debt in this category than in higher rated categories. Standard and Poor's - Speculative Grade Ratinq Debt rated "BB", "B", "CCC", "CC" and "C" is regarded as having predominantly speculative characteristics with respect to capacity to pay interest and repay principal. "BB" indicates the least degree of speculation and "C" the highest. While such debt will likely have some quality and protective characteristics these are outweighed by major uncertainties or major exposures to adverse conditions. BB - Debt rated "BB" has less near-term vulnerability to default than other speculative issues. However, it faces major ongoing uncertainties or exposure to adverse business, financial, or economic conditions which could lead to inadequate capacity to meet timely interest and principal payments. The "BB" rating category is also used for debt subordinated to senior debt that is assigned an actual or implied "BBB" rating. B - Debt rated "B" has a greater vulnerability to default but currently has the capacity to meet interest payments and principal repayments. Adverse business, financial, or economic conditions will likely impair capacity or willingness to pay interest and repay principal. The "B" rating category is also used for debt subordinated to senior debt that is assigned an actual or implied "BB" or "BB" rating. CCC - Debt rated "CCC" has a currently identifiable vulnerability to default, and is dependent upon favorable business, financial, and economic conditions to meet timely payment of interest and repayment of principal. In the event of adverse business, financial, or economic conditions, it is not likely to have the capacity to pay interest and repay principal. The "CCC" rating category is also used for debt subordinated to senior debt that is assigned an actual or implied "B" or "B" rating. CC - The rating "CC" typically is applied to debt subordinated to senior debt that is assigned an actual or implied "CCC' debt rating. C -The rating "C"typically is applied to debt subordinated to senior debt which is assigned an actual or implied "CCC" debt rating. The "C" rating may be used to cover a situation where a bankruptcy petition has been filed, but debt service payments are continued. Cl - The rating "Cl" is reserved for income bonds on which no interest is being paid. D - Debt rated "D" is in payment default. The "D" rating category is used when interest payments or principal payments are not made on the date due even if the applicable grace period has not expired, unless S&P believes that such payments will be made during such grace period. The "D" rating also will be used upon the filing of a bankruptcy petition if debt service payments are jeopardized. Plus (+) or Minus (-) - The ratings from "AX to "CCC" may be modified by the addition of a plus or minus sign to show relative standing within the major rating categories. NR- Indicates no rating has been requested, that there is insufficient information on which to base a rating, or that S&P does not rate a particular type of obligation as a matter of policy. Administration Building STEERING COMMITTEE 10844 Ellis Avenue SAIV Fountain Valley, CA 92708 ORANGE COUNTY SANITATION DISTRICT Agenda Report (714)593 7433 File #: 2021-1815 Agenda Date: 8/25/2021 Agenda Item No: 12. FROM: John B. Withers, Board Chairman SUBJECT: GENERAL MANAGER'S COMPENSATION AND BENEFITS BOARD CHAIR'S RECOMMENDATION RECOMMENDATION: Approve a performance-based non-base building lump sum merit payment of 2.5% for the General Manager based on Fiscal Year 2020/2021 job performance, as authorized in Resolution No. OCSD 19-12. BACKGROUND The General Manager of the Orange County Sanitation District (OC San) is employed on an At-Will basis and serves at the pleasure of the Board of Directors. According to Section 6 of the General Manager's At-Will Employment Agreement, the "District's Steering Committee shall meet with the General Manager in August of each year during the term of this Agreement to review and evaluate his performance over the prior year. The Steering Committee shall make its recommendation(s) to the Board concerning adjustment to the compensation and/or benefits paid or provided to the General Manager, to be effective in July of the year of the review". The General Manager is in the third year of a three-year employment contract. In September 2019, OC San's Board of Directors adopted Resolution No. OCSD 19-12 entitled, "A Resolution of the Board of Directors of the Orange County Sanitation District approving salary increases and salary range adjustments for the General Manager for Fiscal Year 2019/2020, Fiscal Year 2020/2021, and Fiscal Year 2021/2022". The resolution authorizes the Board Chairperson to implement a 3% salary range adjustment and corresponding salary increase for each year of the contract years annually and allows for up to a 2.5% merit increase annually based on job performance as determined by the Board of Directors. The Steering Committee reviewed the General Manager's job performance for Fiscal Year 2020/2021 in closed session in June and July 2021 and recommends that the Board of Directors approve a non- base building lump sum merit payment in the amount of 2.5% for the General Manager. RELEVANT STANDARDS • Offer competitive compensation and benefits Orange County Sanitation District Page 1 of 3 Printed on 8/18/2021 powered by LegistarTM File #: 2021-1815 Agenda Date: 8/25/2021 Agenda Item No: 12. • Maintain positive employer-employee relations • Cultivate a highly qualified, well-trained, and diverse workforce • Comply with OC San policy (Policy 6.1 Appraisal of Performance) and the General Manager's At-Will Employment Agreement PROBLEM The General Manager's current salary market position is at the 81 st percentile, slightly above OC San's targeted 75th percentile for its overall market position. Therefore, the Steering Committee recommends a one-time lump sum merit payment of 2.5% rather than a base-building salary increase to avoid outpacing the comparison agencies. The merit payment is intended to recognize the General Manager's excellent performance over the past fiscal year during the pandemic crisis and to help retain OC San's top executive. Fiscal Year 2021/2022 salary increases for OC San's Executive Management and Managers took effect in July 2021 as approved by the Board of Directors in September 2019. With these increases, the General Manager's salary would be 8.4% above his highest paid direct reports for FY 2021/2022. PROPOSED SOLUTION Approve a performance-based non-base building lump sum merit payment of 2.5% for the General Manager based on Fiscal Year 2020/2021 job performance, as authorized in Resolution No. OCSD 19-12. TIMING CONCERNS In accordance with the General Manager's At-Will Employment Agreement, the Steering Committee shall meet with the General Manager annually to review and evaluate his performance over the prior year. The Steering Committee then reports out on the General Manager's performance evaluation and recommends, for the Board's consideration, any adjustment to compensation. The Board makes the final determination on the compensation payable to the General Manager, which becomes effective retroactively to the first pay period in July. RAMIFICATIONS OF NOT TAKING ACTION Potential retention issue of highly skilled and experienced executive staff and salary compaction issues between General Manager and Executives (direct reports). PRIOR COMMITTEE/BOARD ACTIONS June & July 2021 - Steering Committee reviewed the General Manager's performance evaluation in closed session. September 2019 - Board of Directors adopted Resolution No. OCSD 19-12, specifying annual salary range adjustments, corresponding salary increases, and maximum merit increase for the General Manager for Fiscal Years 2019/2020, 2020/2021, and 2021/2022.

FROM: James D. Herberg, General Manager Originator: Lorenzo Tyner, Assistant General Manager SUBJECT: 2020-21 FISCAL YEAR BUDGET - FINANCIAL CLOSING UPDATE GENERAL MANAGER'S RECOMMENDATION RECOMMENDATION: Information Item. BACKGROUND The preliminary 2020-21 budget financial closing indicates that total expenditures will be approximately $2.6 million below the approved budget. There are three areas of note that warrant additional information: (1) GASB 68 Pension Liability recognition, (2) Capital Improvement Program expenditures, and (3) Other Operating expenditures. 1) GASB Statement 68 - Pension Liability Recognition: GASB 68 requires governments providing defined benefit pensions to recognize their long- term obligation for pension benefits. Orange County Sanitation District (OC San) is a member of the Orange County Employees Retirement System (OCERS). As part of its financial forecasting, OCERS assumes a 7.0% annual return. Returns below 7.0% would result in an additional pension obligation that OC San would be required to recognize on its financial statements. However, the 2020 return was 12.8%, 5.8% above the assumed rate. This increase in return resulted in reducing OC San's pension liability by $11.5 million. GASB 68 requires that pension liability adjustments be recorded in the current fiscal year. This reduced OC San's fiscal year 2020-21 operating expenditures for 2020-21 by $11 .5 million. 2) Capital Improvement Program (CIP) Expenditures: Total 2020-21 CIP expenditures will exceed the approved CIP budget by approximately $10 million. This is a result of accelerated activity within the program, specifically equipment purchases that arrived in late June 2021 instead of the anticipated early July 2021. This required that these expenditures be in the 2021 fiscal year. These expenditures do not represent an overage, just an early receipt of equipment.
