FROM:James D. Herberg, General Manager Originator: Kathy Millea, Director of Engineering SUBJECT: TRICKLING FILTER 480 VOLT CABLE REPLACEMENT AT PLANT NO. 1, PROJECT NO. FR1- 0008 GENERAL MANAGER'S RECOMMENDATION RECOMMENDATION: Recommend to the Board of Directors to: A. Receive and file Bid Tabulation and Recommendation for Trickling Filter 480 Volt Cable Replacement at Plant No. 1, Project No. FR1-0008; B. Award a Service Contract to Baker Electric, Inc. for Trickling Filter 480 Volt Cable Replacement at Plant No. 1, Project No. FR1-0008 for an amount not to exceed $251,586; and C. Approve a contingency of $50,317 (20%). BACKGROUND The Trickling Filters at Orange County Sanitation District (OC San) Plant No. 1, which were completed in 2006, provide approximately 20% of the plant’s secondary treatment capacity. RELEVANT STANDARDS ·24/7/365 treatment plant reliability ·Maintain a proactive asset management program PROBLEM Recently, a number of electrical cables in the Trickling Filter process have shorted out due to a failure with the cables’ insulation. The equipment driven by these cables cannot be operated until the cables are replaced. Repairing the cables is typically not feasible because the location of the short cannot be determined. These failures have significantly impacted the reliability of the trickling filter process. Orange County Sanitation District Printed on 11/23/2021Page 1 of 3 powered by Legistar™ OC6SAN ORANGE COUNTY SANITATION DISTRICT File #:2021-1748 Agenda Date:12/1/2021 Agenda Item No:2. PROPOSED SOLUTION Award a Service Contract for Trickling Filter 480 Volt Cable Replacement at Plant No.1,Project No. FR1-0008. This project will install new power and control cables for 14 affected pieces of equipment. Staff has found from similar projects that additional cables may fail by the time this work is completed.In those cases,it is more cost effective to replace the cable at the time the contractor is mobilized than initiating a new contract.For this reason,staff is requesting a higher-than-usual contingency of 20% to replace additional cables in the same area, should the need arise. TIMING CONCERNS 14 pieces of equipment cannot be utilized until these cables are replaced.Until then,the Trickling Filters process reliability will continue to be reduced. RAMIFICATIONS OF NOT TAKING ACTION The failed equipment would remain out of service which would greatly reduce treatment reliability. PRIOR COMMITTEE/BOARD ACTIONS N/A ADDITIONAL INFORMATION OC San advertised Project No.FR1-0008 for bids on September 2,2021,and two sealed bids were received on September 21, 2021. A summary of the bid opening follows: Engineer’s Estimate $ 337,680 Bidder Amount of Bid Baker Electric, Inc.$ 251,586 Mass Electric Construction Co.$ 323,000 The bids were evaluated in accordance with OC San policies and procedures.A notice was sent to all bidders on October 11,2021,informing them of the intent of OC San staff to recommend award of the Service Contract to Baker Electric, Inc. Staff recommends awarding a Service Contract to the lowest responsive,responsible bidder,Baker Electric, Inc., for a total amount not to exceed $251,586.

OPERATIONS COMMITTEE Agenda Report Administration Building 10844 Ellis Avenue Fountain Valley, CA 92708 (714) 593-7433 File #:2021-1984 Agenda Date:12/1/2021 Agenda Item No:6. FROM:James D. Herberg, General Manager Originator: Rob Thompson, Assistant General Manager SUBJECT: COLLECTION SYSTEM CONDITION MONITORING SERVICE GENERAL MANAGER’S RECOMMENDATION RECOMMENDATION: A. Approve a Five-Year Service and Monitoring Purchase Order Agreement with Hardonex, Inc. (dba SmartCover Systems) for field device communication and monitoring services, for the total amount of $177,778, billed in annual installments; and B. Approve a contingency of $17,777 (10%) for service fee changes due to adding field devices based on the need. BACKGROUND The Orange County Sanitation District (OC San) previously purchased monitoring devices from SmartCover Systems to continuously monitor wastewater and odor levels in the collection system below the manhole cover. These units communicate field conditions back to a computer server via satellite. The field conditions are continuously displayed on a dashboard that generates alarms to staff for abnormal conditions, compiles data used to determine collection system cleaning frequencies, and chemical dosing for odor and corrosion control. SmartCovers have been deployed to measure water levels at potential spill points and areas that could experience surcharging during high flow situations or pump station failures to reduce the risk of sewer spills. SmartCovers are able to provide real time hydrogen sulfide gas levels which allows for the optimization of chemical dosing. SmartCover water level information is also used to determine optimal cleaning intervals for “hot spots” in the collection system.

FROM:James D. Herberg, General Manager Originator: Rob Thompson, Assistant General Manager SUBJECT: USP TECHNOLOGIES INDEMNIFICATION AGREEMENT GENERAL MANAGER'S RECOMMENDATION RECOMMENDATION: Recommend to the Board of Directors to: Approve an Indemnification Agreement with USP Technologies and the Orange County Sanitation District concerning the potential claimed violation of material patents in a form approved by General Counsel. BACKGROUND The Orange County Sanitation District (OC San) operates and maintains a regional wastewater collection system to convey flows from local agencies to its two treatment plants. Wastewater naturally produces corrosive and odorous hydrogen sulfide gas as organic matter decays. Continuous chemical dosing in strategic locations of the collection system, in conjunction with spot slug dosing of caustic soda, inhibits the formation of hydrogen sulfide and other odorous gases. OC San contracts with service providers to provide chemicals and equipment to continuously dose its trunk sewers with these chemicals. OC San has developed a methodology to dose three different chemicals: ferrous chloride, calcium nitrate, and magnesium hydroxide which work together to regulate the hydrogen sulfide formation. The ratio of the chemicals used can be adjusted based on unit price of the commodity and needs of specific sewer locations. OC San applied for and received a patent for this specific three chemical dosing method. Evoqua Water Technologies (Evoqua) has a similar patented process using a two-chemical combination of calcium nitrate and magnesium hydroxide for sewer system odor control. Evoqua sells a calcium nitrate chemical called CAN-9 for use in this patented application which is provided to OC San through USP Technologies. Evoqua is the only supplier of the CAN-9 product and requires its use under its own two chemical patent. Orange County Sanitation District Printed on 11/23/2021Page 1 of 3 powered by Legistar™ OC6SAN ORANGE COUNTY SANITATION DISTRICT File #:2021-1985 Agenda Date:12/1/2021 Agenda Item No:7. RELEVANT STANDARDS ·Protect OC San assets ·12 or fewer odor complaints per year under normal operating conditions in the collection system ·Ensure the public's money is wisely spent PROBLEM OC San intends to utilize its three chemical patent to control odors in its trunk sewers.An alternate calcium nitrate chemical is available which provided an alternate source of supply and is currently cheaper to procure than CAN-9.OC San has contracted with USP Technologies to supply this chemical.The ferrous chloride chemical is supplied by another chemical vendor.USP Technologies is requiring OC San to indemnify them against the possibility of OC San not using ferrous chloride which would cause an infringement of Evoqua’s patent. PROPOSED SOLUTION OC San will continue to use its own patented three chemical dosing system when the alternate calcium nitrate chemical is used.Provide an indemnification to USP Technologies to obtain alternate calcium nitrate CAN-17 and pilot test the chemical for efficacy in OC San's collection system. General counsel and outside legal counsel specializing in patent law have reviewed the attached agreement. TIMING CONCERNS Failing to complete pilot testing of the alternative chemical concentration before contract re-bidding of the calcium nitrate supplier risks higher chemical costs. RAMIFICATIONS OF NOT TAKING ACTION Supplier diversity for calcium nitrate supply in the collection system cannot be achieved per OC Sans Strategic Plan Chemical Sustainability Initiative. PRIOR COMMITTEE/BOARD ACTIONS N/A ADDITIONAL INFORMATION OC San spends approximately $850,000 annually on calcium nitrate.OC San’s patented three chemical system may be more cost effective to use in additional locations.Potential cost savings may be possible by adjusting the dose ratio of the three chemicals with a cheaper calcium nitrate chemical.

This document will continue to change in content and structure to reflect our efforts for continual improvement and to meet the needs of stakeholders. Safe and reliable infrastructure and process equipment are essential to providing industry- leading wastewater collection and management, while achieving our mission and vision statements. We manage asset reliability, mitigate risk, and ensure the quality of our delivered services according to the following stated intent for our Asset Management Program: “OC San will know the condition of assets we own and will have a plan to operate and maintain these assets to deliver the required level of service, at the lowest life cycle cost, with an acceptable level of risk.” ~ James D. Herberg, OC San General Manager Overview of OC San’s Infrastructure OC San owns and operates wastewater collection system infrastructure, as well as two resource recovery and wastewater treatment facilities, located in Fountain Valley and Huntington Beach. Our collection system infrastructure includes 388 miles of regional trunk sewer pipelines and 15 pump stations located throughout the OC San service area (Figure ES-1-1). Wastewater is conveyed to Reclamation Plant No. 1 in Fountain Valley and Treatment Plant No. 2 in Huntington Beach. These facilities treat an average daily wastewater flow of 189 million gallons per day (MGD), serving over 2.6 million people in central and northern Orange County, California. 2021 Asset Management Plan 2 Figure ES-1-1.

The system-level summaries are organized as follows: •Plant No. 1 (Figure ES-1-3 and Table ES-1-1) •Plant No. 2 (Figure ES-1-4 and Table ES-1-2) •Collection System – Pump Stations and Newport Force Mains (Figure ES-1-5 and Table ES-1-3) •Collection – Pipelines (Figure ES-1-6 and Table ES-1-4) The system-level summaries generally include the following fields: •Area No. •Area Name •Average Remaining Useful Life (RUL) Score: Estimated average RUL score for each discipline (civil, structural, mechanical, electrical, and instrumentation) or area based on an average of the RUL scores provided by Asset Engineers in the detailed Area AM Summaries. •Percentage of RUL Scores with 4s or 5s: Percentage based on total number of RUL scores assigned to each area in the detailed Area AM Summaries. The percentage is an alternate metric for the overall condition of the area and equipment. A RUL score of 5 indicates less than 5 years of useful life remains for an asset or set of assets. A RUL score of 4 indicates 5 to 10 years of useful life remains for an asset or a set of assets. •Replacement Value ($ millions): Process area replacement value from the facility valuation. 2021 Asset Management Plan 5 Acronym Key: OCWD = Orange County Water District; RUL = Remaining Useful Life; TBD = To Be Determined; T&D = Thickening and Dewatering ASSET MANAGEMENT SYSTEM SUMMARY – PLANT NO. 1 OVERVIEW Figure ES-1-3.

OC San’s vision supports our mission by expressing what we strive to achieve now and into the future. Our Mission To protect public health and the environment by providing effective wastewater collection, treatment, and recycling services. Our Vision OC San will be a leader in: •Providing reliable, responsive, and affordable services in line with customer needs and expectations. •Protecting public health and the environment utilizing all practical and effective means for wastewater, energy, and solids resource recovery. •Continually seeking efficiencies to ensure that the public’s money is well spent. •Communicating our mission and strategies with those we serve and all other stakeholders. •Partnering with others to benefit our customers, this region, and our industry. •Creating the best possible workforce in terms of safety, productivity, customer service, and training. Through improved and robust asset management practices, we are better able to coordinate and plan actions to ensure our collection system, treatment, and resource recovery infrastructure is safe and reliable, and meets the rigorous level of service embodied by our mission statement. In November 2019, OC San’s strategic planning process resulted in the creation of an asset management policy and asset management initiatives. Collectively, the policy and initiatives make up OC San’s asset management strategy. Asset Management Policy OC San 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. Asset Management Initiatives •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. 2021 Asset Management Plan 12 •Maintain a 20-year forecast of all CIP projects needed to maintain or upgrade the SanitationDistrict’s $10.7 billion in assets on a prioritized risk basis to establish rate structures. The Asset Management Plan is a living document that describes constantly evolving operation strategies, maintenance and refurbishment plans and adaptations, and CIP implementation initially captured in the Facilities Master Plan and revised on an annual basis through the budgeting process. The information included in the Asset Management Plan encompasses the breadth of information needed to successfully align the capital and operational planning activities necessary to meet the Asset Management Program objectives. The key objectives that are built into the Asset Management Program include the following: 1)Take a proactive approach to repair, rehabilitation, and replacement. 2)Ensure assets are reliable and operating when needed. 3)Minimize unplanned outages and equipment downtime. 4)Manage risks associated with asset or service impairment through asset performance optimization. 5) Develop cost-effective management strategies for the long term. 6)Strive to implement world class asset management strategies through continual improvement in our asset management practices. The Asset Management Plan is a key component of OC San’s overall planning activities. It aligns with the OC San’s Strategic Plan, and the Facilities Master Plan and projects identified therein, while identifying potential and new opportunities that may require funding in the budget development process. Table 1-1 describes the relationship of the Asset Management Plan to the other planning activities.

Linkage between Asset Management Plan and Other Planning Activities Planning Activity Description Planning Horizon Update Cycle Strategic Plan Defines the strategic initiatives to be pursued by OC San and provides a basis for long-term financial, capital, and operating planning. The Asset Management Plan aligns with Strategic Plan goals and objectives. 5-to 10-year Biennial Facilities Master Plan Identifies long-term capital improvement plans to address treatment and collection system infrastructure improvement needs. Projects identified in the Facilities Master Plan are incorporated into the Asset Management Plan and refined as appropriate. 20-year Varies Asset Management Plan Documents the overall condition of treatment and collection system assets and plans to address key condition and performance issues to ensure assets meet OC San’s levels of service. 1-year 5-year 10-year Annual Budget Document Lays out the framework of OC San’s activities and serves as a source of information for our Board of Directors, rate payers, and employees. It includes operational, capital, and debt service expenditures necessary to support our mission and to execute the Strategic Plan adopted by our Board of Directors. The Asset Management Plan identifies new operational, maintenance, and capital improvement activities for consideration during the budget development process. 2-year Annual 2021 Asset Management Plan 14 1.1 Overview of OC San’s Infrastructure OC San is responsible for providing wastewater collection, treatment, and recycling services to over 2.6 million people in central and northern Orange County, California. OC San’s two resource recovery and wastewater treatment facilities treat an average daily wastewater flow of 189 million gallons per day (MGD) from residential, commercial, and industrial sources. In addition to our plant facilities, OC San owns and operates wastewater collection system infrastructure. Our collection system infrastructure includes 388 miles of regional trunk sewer pipelines and 15 pump stations located throughout OC San’s service area (Figure 1-1). Wastewater is conveyed via the collection system to Reclamation Plant No. 1 in Fountain Valley, and Treatment Plant No. 2 in Huntington Beach, where resource recovery and wastewater treatment take place. OC San’s treatment plants currently operate under a regulatory permit from the Regional Water Quality Control Board (RWQCB). This authority is established through the National Pollutant Discharge Elimination System (NPDES) that permits the discharge of treated wastewater through an ocean outfall system to the Pacific Ocean. While some of this treated water is released five miles offshore through a deep-water ocean outfall system, most is recovered and delivered to the Orange County Water District (OCWD). OCWD further treats OC San’s effluent, using the Groundwater Replenishment System, which improves the effluent water quality, to drinking water standards for groundwater recharge and irrigation purposes. The following sections briefly describe the key systems under OC San’s management. Central and Northern Orange County titttttt 2.6 tttt million people served 2021 Asset Management Plan 15 Figure 1-1.

OC San’s 388 miles of collection system pipelines and 15 pump stations are spread throughout northern Orange County and include 363 miles of gravity pipelines, 21 miles of force mains, 4 miles of inverted siphons and 4,471 manhole structures. 363mi gravity pipelines 4mi I 111 ': , inverted siphons 21mi C n- force mains manhole structures 2021 Asset Management Plan 17 1.1.2 Reclamation and Treatment Plant System OC San owns and operates two wastewater treatment plants that serve two primary functions— treatment and reclamation. Reclamation Plant No. 1 (Plant No. 1) is located in the city of Fountain Valley, approximately 4 miles inland of the Pacific Ocean and adjacent to the Santa Ana River. Influent wastewater entering Plant No. 1 passes through a flow metering and diversion structure, mechanical bar screens, grit chambers, and primary basins, before going to one of two air-activated sludge processes, or trickling filters, and secondary clarifiers. Up to 135 MGD of secondary effluent can be diverted to OCWD’s facilities for tertiary treatment prior to reuse. The remaining flow goes to the Plant No. 2 ocean outfall system. For a map of the facilities and more detailed understanding of how Plant No. 1 processes work together, please refer to Appendices A and B, respectively. Solids treatment at Plant No.1 includes co-thickening of primary and secondary sludge, followed by anaerobic digestion process and centrifuge dewatering of digested sludge to produce Class-B biosolids. Digester gas produced at Plant No. 1 is collected, cleaned, compressed, and transferred via a closed piping system, to the Central Power Generation Facility, as a renewable fuel for energy generation. In addition, Plant No. 1 includes facilities for odor control and chemical addition to support the aforementioned Treatment Plant No. 2 (Plant No. 2) is located in the City of Huntington Beach, adjacent to the Santa Ana River and east of Pacific Coast Highway. Raw sewage flow entering Plant No. 2 passes through a flow metering structure, mechanical bar screens, and grit removal chambers. Flow then passes through primary basins before being split between the oxygen activated sludge secondary treatment facility or the trickling filters/solids contact basins, where it is finally discharged directly to the ocean via the outfall pumping system. Solids treatment at Plant No. 2 includes dissolved air flotation thickening of waste-activated sludge (WAS) and secondary sludge, anaerobic sludge digestion of primary and thickened secondary sludge, and centrifuge dewatering of digested sludge to produce Class-B biosolids. Plant No. 2 also has facilities for odor control and chemical addition. Digester gas produced at Plant No. 2 is collected, compressed, cleaned, and distributed to a Central Power Generation System as a renewable fuel for energy generation. Compressed digester gas can be shared between the plants through the interplant gas line. Currently, Plant No.2 secondary effluent is discharged to the ocean through the outfall system. After the construction of OCWD’s Groundwater Replenishment System (GWRS) final expansion and associated projects in 2023, Plant No. 2 reclaimable secondary effluent together with Plant No. 1 secondary effluent (a total of up to 175 MGD) will be diverted to OCWD for tertiary treatment and reuse. For a map of the facilities and more detailed understanding of how Plant No. 2 processes work together, before and after the final expansion of GWRS, please refer to Appendices C, D, and E, respectively. 2021 Asset Management Plan 18 1.1.3 Outfall System The ocean outfall system includes three discharge structures: Outfall No. 1, Outfall No. 2, and the Santa Ana River Emergency Overflow Weirs. Outfall No. 2 serves as the primary ocean outfall, discharging treated wastewater approximately 5 miles offshore at a depth of approximately 200 feet. It began service in 1971 and is currently undergoing planned assessment and rehabilitation activities to ensure its reliability for many years to come. Outfall No. 1 serves as an emergency outfall. It was originally constructed in 1954 and was later modified in 1965. It is located over a mile offshore at a depth of approximately 65 feet and serves as a primary backup to Outfall No. 2. OC San’s NPDES permit specifies that this outfall can only be used in the case of an emergency or during planned maintenance activities. The outfall system has two Santa Ana River Emergency Overflow Weirs at Plant No. 2, which discharge directly to the Santa Ana River. These weirs are for extreme emergency use only and serve as a secondary backup to the primary outfall facilities, ensuring the safety and welfare of the community at large. OUTFALL NO. 2 PRIMARY OCEAN OUTFALL 1200 5 inches in diameter miles long 480 million gallons per day rated capacity OUTFALL NO. 1 EMERGENCY OUTFALL 780 1 inches in diameter mile long 245 million gallons per day rated capacity 2021 Asset Management Plan 19 1.2 Facility Valuation As part of the 2017 Facilities Master Plan, OC San commissioned an engineering study to determine the 2017 valuation of all OC San capital facilities, including Plant No. 1, Plant No. 2, interplant and joint treatment facilities, and the collection system, including sewer pipelines and lift stations. Figure 1-2 shows the valuation information, presented in five general sub-process areas: •Collections Systems Piping •Collection Systems Pump Stations •Reclamation Plant No. 1 Facilities •Treatment Plant No. 2 Facilities •Interplant, Joint, and Common Facilities Figure 1-2.

Every part of our organization is involved in some aspect of asset management and ensuring that assets are designed, constructed, operated, and maintained to reliably deliver the required level of service to our customers. Through a very collaborative effort, each group plays an important role in ensuring that the individual asset management initiatives are properly executed (Figure 1-3). Figure 1-3. Roles in Asset Management •Operations operates and monitors assets and infrastructure that convey, treat, process, and recover resources. •Maintenance performs proactive, corrective, and restorative activities in a planned setting to maintain asset reliability and capacity. •Engineering Planning provides engineering support for short- and long-term management of assets, while working towards asset management objectives. •Project Management manages design and construction of new facilities and the rehabilitation of older facilities. The Small Projects Delivery team within the Project Management Office is responsible for the design and construction management of facilities and maintenance projects. 2021 Asset Management Plan 21 •Engineering Design ensures projects and assets are designed in accordance with engineering standards and codes and meet stakeholder needs. •Construction Management ensures assets are constructed in accordance with contract requirements. To fulfill our commitment to our ratepayers for providing safe and reliable services, OC San’s Asset Management Program is structured to align the Engineering, Operations, and Maintenance (O&M) departments. OC San’s Asset Management Group, within the Engineering Planning Division, consists of nine Asset Engineers responsible for understanding the key issues or concerns related to the condition of OC San’s assets and for developing and coordinating plans or strategies to ensure that the assets operate reliably and are functioning properly. The Asset Engineers, assigned to their respective process or collection system area(s), work closely with the O&M Area Team members to maintain familiarity with all aspects that may impact the operational, condition, process, and maintenance-related issues within their assigned areas. Collectively, the Area Teams work together to reach the goal of providing the required level of service to our customers, at the lowest lifecycle cost with an acceptable level of risk. This strategy involves a significant investment in internal coordination but ensures that we are properly assessing risks, solving problems and process deficiencies in a timely manner, and providing optimal water treatment services. The mission of the Maintenance Division is to protect public health and the environment by providing reliable power distribution, electrical and instrument maintenance, civil facilities and grounds maintenance, and mechanical maintenance to the treatment plant and associated pump stations in outer lying service areas. The Maintenance Division provides required predictive, preventive, and corrective maintenance and planning activities to include project support in design and construction phases, collectively referred to as reliability-centered maintenance (RCM). The goals of RCM involve implementing well-coordinated maintenance strategies to ensure OC San’s assets will operate at the required level of service. 1.3.1 Predictive Maintenance OC San takes a proactive RCM approach emphasizing Predictive Maintenance (PdM). The Maintenance Reliability Group implements the PdM Program, which collects data through condition monitoring, enabling the real-time performance of assets. Methods of data collection are Insulation Resistance testing, Infrared Thermography, Structure Borne Ultrasound, Electrical Signal Analysis, Vibration Analysis, and Oil Analysis. The premise of PdM is a proactive approach to minimize unexpected breakdowns, reduce repair cost, extend the Mean Time Between Failure (MTBF), monitor the actual equipment health through quantifiable means, and perform advanced analysis and failure detection. In addition, when sudden changes or variations in the process manifest, they are often found during the regular Maintenance Reliability rounds as part of their everyday work. The ability to monitor equipment lends itself to helping Maintenance to optimize intervals between corrective repairs, minimizing the number and cost of unscheduled repairs created by machine-train failures, and improving the overall equipment reliability. 2021 Asset Management Plan 22 Figure 1-4. PdM Summary The Maintenance Specialists and Reliability Technicians in this group use various techniques such as: •Vibration analysis to measure imbalance in rotating equipment. •Thermography to measure excessive temperature rise. •Oil and wear debris analysis to predict lubricant and equipment degradation. •Ultrasound inspection of electrical power distribution equipment for detecting corona and other destructive conditions that pose a potential for arc flash incidents. •Motor circuit analysis of de-energized motors, large or small, for diagnosing condition of the motor and its associated power circuits for determining motor stator health, broken rotor bars, deteriorating motor connections, and any impending failure trends. •Motion Amplification amplifies a regular video frame of operating equipment, turning each camera pixel into a pseudo-accelerometer, which allows for an advanced analysis of machine faults. In addition, it augments other reliability analysis tools for troubleshooting purposes. OC San has a two-decade history of PdM as summarized in Table 1-2.

High-Level Summary of OC San's Predictive Maintenance Program Year Activity 2002 Baseline vibration monitoring with consultant assistance 2006 Comprehensive vibration analysis program implementation at both treatment plants and 15 pump stations 2012 Comprehensive predictive maintenance program implementation and establishment of Reliability Maintenance Team that includes engineers and four Reliability Maintenance Technicians 2014 Predictive maintenance program assessment conducted by Allied Reliability Inc. 2018 Machinery lubrication program assessment conducted by Noria Corporation Inc.; added ultrasound and thermography to test electrical equipment 2019 Motion Amplification equipment by RDI Technology added to the Predictive Maintenance Program 2020 Motor circuit analysis for large and small motors 1.3.1.1 Mechanical Discipline The mechanical discipline has the most mature PdM Program and involves variance trending of the PdM test results, which include: •Vibration analysis •Oil analysis •Airborne Ultrasound •Infrared thermograph •IRIS motion camera (measures deflection and displacement) In addition to PdM activities for mechanical equipment, OC San also uses laser alignment techniques to enhance alignment rotating machinery accuracy to increase operating life span. 1.3.1.2 Electrical Discipline The electrical PdM Program continues to evolve and currently includes the following tests: •Oil analysis for transformers •Ultrasound to detect arcing •Infrared thermography to detect hot spots •Electrical power distribution equipment preventive maintenance •Circuit breakers and protective relays preventive maintenance and testing •Motor circuit analysis for large and small motors •Medium voltage feeder cable testing to determine the health of cables and insulation 2021 Asset Management Plan 24 1.3.2 Preventive and Corrective Maintenance Beyond the advanced PdM strategies, OC San also performs time and cycle-based preventive maintenance (PM) and corrective maintenance (CM) activities. It is these activities that, if well implemented, greatly extend the life of the assets. Recognizing the importance of these efforts, OC San has dedicated two groups of skilled individuals to reinforce and sustain these activities. •OC San has created a PM Optimization Group that is tasked with conducting an in-depth assessment to optimize preventive maintenance strategies for new and existing assets and to establish maintenance approaches and strategies for assets installed by capital improvement projects prior to beneficial occupancy. The PM Optimization Program tracks, maintains, and manages assets throughout their lifecycles from design, construction, commissioning, beneficial occupancy, operations, and maintenance, to the eventual decommissioning or replacement of assets. This ensures that asset lifecycle is maximized with the lowest risk to process failure by achieving the intended reliability, at the lowest possible cost, and maximizing equipment availability. •The Maintenance Planning Group drives reliability and effectiveness in the craft-based maintenance work groups they support by ensuring that work groups have sufficient ready- to-execute work with appropriate resources such as tools, materials, labor, and job plans. Maintenance Specialists in this group are responsible for managing blanket maintenance service contracts, planning and scheduling maintenance activities, optimizing preventive maintenance activities within Maximo (which includes fine tuning job plans based on input received from field staff, leads, and maintenance Supervisors and Engineers), and coordinating complex maintenance activities involving shutdowns and outages. OC San’s preventive and CM program is staffed to address the long-term reliable performance of civil, mechanical, electrical, and instrumentation assets. PM and CM activities specific to these disciplines are an integral part of OC San’s maintenance program. The following lists provide examples of tasks performed; however, they are not meant to be inclusive of all maintenance responsibilities. Often, OC San staff get the job done by improvising in the field setting to meet the challenge. 1.3.2.1 Civil Discipline PM and CM activities include: 1)Cleaning of civil facilities. 2)Chemical conditioning of the sewage to reduce corrosion and control odors. 3)Minor repairs. 4)Application and repair of coatings. 5)Maintenance and testing of cathodic protection systems. 1.3.2.2 Mechanical, Electrical, and Instrumentation Disciplines PM and CM activities include: 1)Valve and gate exercising program comprising more than 264 PM tasks for over 1,650 valves and gates in both plants and collection system. 2)Equipment rotation program to ensure equipment wear is predictable. 3)Adjustments and mechanical alignments. 4)Equipment rebuilding and regular testing. 5)Changing of lubricants and filters. 6)Electrical equipment cleaning and tightening. 7)Sensors and meters calibration. 2021 Asset Management Plan 25 2 State of OC San’s Infrastructure The Area Asset Management (AM) Summaries are intended to summarize the condition of major assets, identify key issues for further investigation, and summarize maintenance and CIP projects planned over the next 10 to 15 years. The approach for developing the AM Summaries is to assemble a list of major assets, document key issues, define the average remaining useful lives of these assets, and identify OC San’s plan to address performance and reliability issues of these assets over the 1-, 5-, and 10-year planning horizons. Each month, Asset Engineers present one or more of the AM Summaries to the AM Council; over the course of a year all the process areas, pump stations and collection system are presented. The Area AM Summaries are updated as needed and incorporated into the Asset Management Plan, which is published annually. 2.1 Asset Management System Summaries The following system-level summaries provide a high-level overview of the Area AM Summaries contained in Section 2.2. The remaining useful life (RUL) scores are an average of the RUL scores for that discipline within that process area. Detailed condition scores are presented in the Area AM Summaries. The system-level summaries are organized by: •Plant No. 1 •Plant No. 2 •Collection System – Pump Stations •Collection System – Pipelines The system-level summaries include an area map showing the general layout of the process areas or collection system, and a table with the following fields: •Area No. •Area Name •Average RUL Score: Estimated average RUL score for each discipline (civil, structural, mechanical, electrical, and instrumentation) or area based on an average of the RUL scores provided by Asset Engineers in the detailed Area AM Summaries. •Percentage of RUL Scores with 4s or 5s: Percentage based on total number of RUL scores assigned to each area by Asset Engineers in the detailed Area AM Summaries. The percentage is an alternate metric for the overall condition of the area. A RUL score of 5 indicates less than 5 years of useful life remains for an asset or set of assets. A RUL score of 4 indicates 5 to 10 years of useful life remains for an asset or a set of assets. •Replacement Value ($million): Process area replacement value from the 2017 facility valuation. 2021 Asset Management Plan 26 Acronym Key: OCWD = Orange County Water District; RUL = Remaining Useful Life; TBD = To Be Determined; T&D = Thickening and Dewatering ASSET MANAGEMENT SYSTEM SUMMARY – PLANT NO. 1 OVERVIEW Figure 2-1.

Some assets have very little remaining life or have failed already and will need interim solutions before they are addressed by the project, such as exhaust fans and ducts in Rag/Grit Room. •Continue to actively monitor the condition of aging assets scheduled for repairs/replacement under P1-105 and develop temporary/minimal solutions as applicable until a permanent solution is provided by P1-105. •Fugitive Odors – Presence of fugitive odors at the headworks area was noted. Upon further investigation four major sources of contribution were identified which included splitter boxes, bin loading structure, headworks scrubbers and metering and diversion building. •Corrective actions were taken at all the identified locations to eliminate or minimize presence of fugitive odors until P1-105 replaces the foul air system in this area. •Headworks Vulnerability Assessment – Evaluate bar screens and other equipment to identify vulnerabilities and weak points within the Headworks process based on a high debris/ragging event. •Review design criteria and operating philosophies for P1-105 and identify assets that lack redundancy and may fail during a high debris/ragging event. Provide recommendations to improve headworks process resiliency. •Headworks 1 Capacity – Existing pumps at Headworks 1 were deemed unreliable to provide sufficient pumping capacity during wet weather. P1-105 bypass will be installed in 21-22 wet weather season. •A temporary pumping system will be installed by P1-105 during wet weather season of 21-22 to provide sufficient pumping capacity.

These issues require ongoing attention from maintenance and can affect Plant No. 1 treatment capacity. •Several projects are planned to address rectangular primary basin issues and reliability including P1-133 and X-017. However, these projects cannot make the rectangular basins maintenance free. OC San should expect to dedicate a significant amount of maintenance and operations labor hours to these basins, especially during times when capacity is reduced by projects. •Construction Sequencing – There are many upcoming projects that will perform work on the Plant No. 1 primary treatment system. These projects are largely interdependent on one another and will temporarily impact the primary capacity at Plant No. 1. •Continue to holistically assess the capacity/treatment consequences of the upcoming projects, especially if schedules change during design and construction. •Circular Primary Basin – Influent pipes to circular basins 3 and 4 were identified with cracks and leaking joints. To maintain desired peak flow capacity of 320 MGD, the circular basins are required to be in service.•Develop repair options and implement an interim solution until P1-126 replaces the circular sedimentation basins. •Scum Management – The scum collection system in rectangular primary basins have been experiencing operational issues such as trapped scum in various locations, overflow and failure of scum tipping troughs, and clogs in the scum pits and scum pumps. •Two studies are planned to evaluate options to improve scum collection in rectangular primary basins, RE19-01 and PRN- 00563. RE19-01 is focused on the use of new equipment in the scum pits such submersible chopper pump to address clogging issues. PRN-00563 will perform a comprehensive evaluation of the scum collection system and provides recommendations. •Primary Effluent Piping Manhole – The Primary effluent piping from rectangular basins is equipped with two pressure manholes for access to the piping. The pressure manhole located on the eastside piping has experienced sever corrosion and must be replaced. •Eastside pressure manhole cover and pressure plate must be replaced to prevent manhole cover failure. The westside pressure manhole requires additional cover to avoid collection of surface runoff water on top of pressure plate and to prevent further corrosion.

Current plan is to use the information from the assessment to create larger CIP projects that can improve the piping network throughout the plant. Smaller repairs will be done using on-call contractors and maintenance/asset issues projects. •City Water Pump Station – Pumps are possibly undersized.•The three medium pumps at the City Water Pump Station continuously run causing excessive wear. There is one smaller jockey pump that runs very infrequently. PRN-00541: Plant No. 1 City Water Demand Flow Assessment is expected to properly size the pumps at the station to meet the current needs of the plant. •Plant Water – Piping failures. •Due to the corrosive nature of the plant water, the current ductile iron pipes are corroding prematurely and causing failures throughout the plant. FE19-02 will address aging plant water piping at Cen Gen and FE20-05 will address recent plant water pipe failures at the secondary clarifiers. Overall goal for these and future projects is to replace ductile iron pipes with either Fiberglass Reinforced or HDPE piping material. •Reclaimed Water System – This system needs a pressure regulating valve installed. • Due to recent operational changes at OCWD, Reclaimed water pressure has increased to 100-130psi, however, OC San plant water has remained at 80 psi. In order to prevent using reclaimed water when plant water is plentiful, a pressure regulating valve installed at the OCWD/OC San reclaimed water connection point is necessary.

The Bleach Station is minimally used to disinfect plant water, but the Sodium Bisulfite Station was inactive since then. Both systems need to be available in case the Short Outfall is used during emergencies or planned maintenance. •OC San installed a temporary tote system for sodium bisulfite in case of emergency. •OC San will procure and install a temporary tank to replace the tote system and increase the storage capacity. The tank will be in service until P2-135 Sodium Bisulfite Station Rehabilitation completion. •P2-98A will demolish the existing Bleach Station and build a new Bleach Station that primarily serves as an odor control for new primary sedimentation basins. The new station has a provision to disinfect effluent if needed. •Ocean Outfall Capacity and Maintainability Strategy- After J-117B completion, Low Flow Pump Station will be the main mode of operation, and OOBS and EPSA will stay standby. Due to low flow and low probability of high flow events, assets required for high flow will be difficult to exercise and maintain. •OC San will start a planning study to evaluate future required outfall capacity and develop a comprehensive plan to maintenance outfall assets. •Reliability of Long Ocean Outfall– PS18-09 Ocean Outfall Condition Assessment and Scoping Study is in progress to develop a detailed scope of work for the future X-053 Long Ocean Outfall Rehabilitation. The project identified few critical parts, such as tie rods, that have corroded and need to be repaired in near future. •Immediately required repairs will be executed as a standalone project before the X-053 •X-053 Long Ocean Outfall Rehabilitation is scheduled to start in 2023 •Short Ocean Outfall Assessment – Short outfall was last used in 2012 to support J-112A construction. Inspection was not a part of compliances until new NPDES permit was renewed in 2021. The outfall was built in 1952 and requires a thorough assessment to ensure its availability and reliability. •OC San will start a planning study for the Short Outfall similar to the PS18-09 Ocean Outfall Condition Assessment and Scoping Study.

Also, pump station infrastructure is often located in the public right of way making safe access to these facilities an ongoing issue. •An ongoing planning study (PS18-06) is reviewing and interpreting electrical code and will establish OC San design standards to address this issue. Practicing ongoing safety measures and traffic control when working in the public right of way will continue to be of the utmost importance. •Natural Phenomenon – Edinger pump station is located immediately adjacent to an undersized flood control channel. Crystal Cove pump station is experiencing gradual site settlement. Both natural hazards present a risk to normal operation of the pump stations. •A capital project (11-33) has been established to replace and relocate Edinger pump station. A planning study (XPS0049) has been established to determine the necessary mitigation measures to remediate site settlement at Crystal Cove pump station. •Increased Methane Gas Levels – Methane gas accumulation has become a safety concern at some pump stations. The amount of gas seems to increase during summer months and presents a unique challenge because of the short response time necessary to address the safety concerns of increased ignition risk. •OC San crews respond to alarms that indicate increased levels of methane gas. A multi-division task1 force has been established to address this issue. The effort includes in-depth liquid and air sampling, installation of a two-stage unit to treat odorous air pulled from Bitter Pt. pump station, and finally establishing an operation strategy for the force main system. •Corrosion – Corrosion is an ongoing problem in this very harsh environment. In places where the system has been kept from venting and mixing of wastewater is prevalent, such as wet wells, the degree of corrosion has (or will soon) require the replacement/rehabilitation of the assets. •Visual assessments of known corrosion issues are performed on an ongoing basis. When necessary, cameras are used to evaluate the spreading of corrosion impacts and confined space entry may be performed to gather additional information to determine when the facility needs to be rehabilitated. •Groundwater Intrusion – Groundwater has penetrated four of the newly constructed pump stations in the coastal region of the service area. Groundwater is notoriously corrosive and may compromise the strength of the rebar within the concrete structure walls. •Execute a planning study (XPS0065) to identify possible mitigation measures. •Maintenance Access – In some cases, such as venting of the Newport Beach force main system, access to critical facilities is limited by safety and public impact concerns. In other cases, such as MacArthur Pump Station force main, access to critical facilities is not possible because redundancy was not considered when the pump station was designed. •OC San continues to improve planned maintenance processes and inter-agency coordination that allow crews to minimize impacts to the community during necessary maintenance operations. A capital project (7-68) has been established to construct a redundant force main to serve MacArthur Pump Station. •Valve Operability and Reliability – In many aging pump stations, isolation valves, check valves and force main valves are starting to fail or becoming difficult to operate due to age, debris and corrosion. These valves are critical to the operability and reliability of OC San pump stations and will require replacement. •Multiple valve replacement projects (PRN-00572, PRN-00734, PRN-00790, PRN-00808) have been identified and efforts are being made to prioritize these projects so they can be executed in a timely manner to ensure OC San pump stations can continue to operate reliably. •Property Acquisition – Many of OC San pump stations are located in tight spaces with limited access. This present challenges for crew to perform routine maintenance or execute projects. •OC San continues to evaluate suitable sites to acquire properties for pump stations that will soon be rehabilitated or replaced, such as Slater and College pump stations.

During peak wet weather flows, capacity issues were identified in a portion of the North Trunk and Tustin Avenue sewers. •Project 7-69 will upsize a portion of the North Trunk to address existing capacity issues and Project X-084 will upsize a portion of the Tustin Avenue sewer to existing capacity issues. •Groundwater Infiltration – CCTV identified significant areas experience significant groundwater infiltration, primarily concentrated parallel to the I-405 corridor. •Project 7-65 will address all areas with significant groundwater infiltration by rehabilitating the affected pipeline segments with grout and new interior lining. •Pipeline Fracturing – CCTV identified several areas with significant fracturing of VCP pipelines. The largest concentration of fractures is concentrated in the Fairview Trunk. •Project 6-20 will rehabilitate the entire Fairview Trunk to address pipeline fractures. Projects 3-66, 7-65, and X-068 will also address fracturing with rehabilitation work. •Root Intrusion – CCTV identified significant root intrusion in numerous segments of the sewer trunks in Orange and Tustin. Some blockages in OC San sewer mains may have contributed to a local sanitary sewer overflow in 2021. •A hotspot PM has been created for areas with the worst root intrusion for more frequent cleaning. Additionally, OC San is evaluating the need for a blanket contract for chemical treatment for root control. Project X-068 will address the permanent rehabilitation of pipeline segments damaged by root intrusion. •Point Repairs – There are isolated pipe segments with structural and operational defects that are not part of a current project. Most isolated areas are north of the Project 7-65 work area and an additional spot in between the FE18-08 and X-084 project areas. •OC San staff will evaluate the extent of the necessary repairs in these locations and recommend blanket contract work orders or small projects to address the most significant defects. It is recommended that the frequency of monitoring of pipelines with RUL scores of 4 or 5 be increased. •Cleaning and Condition Assessment of Siphons and Large Diameter Pipelines – Siphons are regularly cleaned but are not inspected because they are inaccessible using CCTV equipment. Large diameter pipe (> 42”) are not cleaned and CCTV footage does not identify sediment or debris below the waterline. OC San staff has identified potential risks in sewers upstream of the Santa Ana River siphon. •OC San staff will review recent sonar inspection data that identifies amount of debris in select large diameter pipelines. Based on the results, OC San staff will recommend additional sonar inspection or large diameter cleaning where necessary. •Manhole Access – OC San staff has identified specific locations where manholes are difficult to access for maintenance. Current issues exist with manholes in some OC San easement areas and along the Santa Ana River. •OC San staff will track and prioritize access issues to address key concerns. High priority access improvements will be recommended as a small project or addition to an existing project.

To support the evaluation, OC San developed metrics for monitoring. The metrics described below have been chosen to directly relate to the Asset Management Program objectives. The key objectives OC San is building into the Asset Management Program are as follows: 1)Take a proactive approach to repair, rehabilitation, and replacement. 2)Ensure assets are reliable and operating when needed. 3)Minimize unplanned outages and equipment downtime. 4)Manage risks associated with asset or service impairment through asset performance optimization. 5)Develop cost-effective management strategies for the long term. 6)Strive to implement world class asset management strategies through continual improvement in our asset management practices. Starting last year, OC San has chosen to focus on the first three objectives and in so doing, has also met the intention of objective number six, continual improvement. The following metrics were chosen not only to demonstrate the effectiveness of the Asset Management Program but also to establish a baseline for which to gauge future performance. It is expected that the Asset Management Council will meet and after reviewing the information in this report, will discuss Asset Management Program metrics in greater length including the utility of the metrics chosen for the 2021 Asset Management Plan and the possibility of setting agency goals. The proactive maintenance percent, the percent of PM as a total of all maintenance, demonstrates the effectiveness of the maintenance program (proactive vs. reactive). It also may reflect the condition (including age) of the assets. Availability percent demonstrates the average asset availability by process area and speaks to whether the assets are operating when needed. It is implied that when the assets are available, they are also reliable; however, this may or may not be the case. OC San staff tried diligently to develop a metric that measures reliability; however, current data capture processes limit how the data can be used and the nature of the chosen reliability metric was not appropriate for the level at which the data are being reported. For now, availability is our best measure of objective number two. Break-In percent illustrates the amount of emergency work (or reactive work) as a percent of total work in the process area. The break-in percent metric will give OC San personnel a better understanding of unplanned outages and the causes of equipment downtime. Finally, maintenance costs and labor hours are presented by process area to illustrate the total resources devoted to maintaining the process areas. The methods used to calculate each metric are included in Appendix F. 3.1.1 Data The data used for the following analysis comes from two different sources. The data used for asset availability were sourced from the OC San Major Equipment Status (MES) Dashboard database. The original intent of the MES Dashboard was to provide a targeted overview of critical asset availability allowing management to gauge if the area can meet OC San level of service commitments. The MES data source provides a narrow and targeted group of major assets that are critical to the operation of the process areas. Each piece of equipment is placed “in” or “out” of service by staff. 2021 Asset Management Plan 118 All other metric data were sourced from the computerized maintenance management system of record, Maximo. In contrast to the availability metric, the other metrics presented include most assets in each process area, some of which are not as critical to the successful operation of the process area. A mitigation to using this larger subset of assets exists in the break-in (reactive work) metric, which includes work that is deemed “emergency” or “urgent” by staff. By implication, this population of assets includes higher risk assets. The data from each database are from FY2018-19, 2019-20, and 2020-21 and is included in Appendix F for reference. 3.2 Program Metrics 3.2.1 Proactive Maintenance Percent The Proactive Maintenance Percent is the percent of PM as a total of all maintenance performed. An increase in proactive maintenance percent represents a shift from reactive to a proactive maintenance program. As shown in Tables 3-1 and 3-2, the proactive maintenance percent for both Reclamation Plant No. 1 and Treatment Plant No. 2 is consistent and does not show any remarkable increase or decrease for either facility. A proactive maintenance percent of 80% is considered best in class value based on manufacturing industry standards which may not be comparable to a critical facility as wastewater treatment but helpful to have as a guideline. Many of the areas at both plants were at or below 60% indicating that improvement in this area is likely over time as proactive maintenance programs are implemented and older facilities are replaced. Table 3-1. Proactive Maintenance Percent for Reclamation Plant No. 1 Process Area FY 18/19 FY 19/20 FY 20/21 Preliminary 25% 39% 39% Primary 29% 39% 32% Interplant 69% 84% 82% Activated Sludge 58% 53% 64% Trickling Filters 55% 56% 53% Digesters 34% 46% 46% Solids Handling Facilities 31% 34% 42% Central Power Generation 40% 64% 62% Electrical Distribution 77% 68% 65% Utilities 43% 33% 30% Table 3-2.

Proactive Maintenance Percent for Reclamation Plant No. 2 Process Area FY 18/19 FY 19/20 FY 20/21 Effluent Disposal 61% 57% 35% Digesters 39% 39% 55% Solids Handling Facilities 35% 41% 53% Central Power Generation 58% 42% 50% Electrical Distribution 84% 70% 74% Utilities 34% 39% 44% At Plant No. 2, the proactive percent for the solids handling facility increased in FY20/21 when the new dewatering facility started operating, and the older belt press facility was decommissioned and demolished. The proactive percent for primaries was 25% in FY19/20 because a construction project was rehabilitating the primaries. Although the pump stations have proactive maintenance percentages over 60% shown in Table 3-3, the amount of percent change is the defining characteristic of the data. Decreases of 20% are indicative of emergency work that was required and will be reflected in the break-in percentage illustrated later in this chapter. For instance, Bay Bridge required emergency work to replace leaking valves for contractor work and Lido had tree root intrusion that requirement immediate attention. Common CM work orders include replacing leaking valves, replacement of pump packing, de-ragging pumps, and attending to equipment that is making excessive noise when operating will also reduce the proactive percent. Table 3-3.

In general, the major equipment was available over 88% of the time ensuring the level of service was met for all process areas. For a list of availability percent by process area for FY 20/21, refer to Table 3-4. Table 3-4. Asset Availability for FY 20/21 Process Area Plant No. 1 Plant No. 2 Preliminary 99% 92% Primary 97% 88% Activated Sludge 93% 92% Trickling Filters 100% 91% Effluent Disposal 94% 89% Digesters 99% 88% Solids Handling Facilities 99% 99% Central Power Generation 96% 92% Electrical Distribution 100% 95% Utilities 98% 94% In the primary treatment area, availability percent is reduced due to an increase in the number of major equipment components needed during the wet weather season, not because the equipment was taken out of service. Plant No. 2 shows lower availability percent in the primary and effluent disposal facilities because equipment is out of service for contractor work. The digesters at Plant No. 2 saw a decrease because Digester were intentionally removed from service for cleaning and repairs. This is an extensive effort to make the digesters more reliable with the implementation of several maintenance rehabilitation projects over the next 6 years. Major equipment was predominately available at the pump stations with availability percent greater than 90% for FY 20/21 shown in Table 3-5. Table 3-5. Availability Percent for the Pump Stations Pump Station FY 19/20 FY 20/21 ‘A’ Street 100% 98% 15th Street 97% 98% Lido 98% 94% Bay Bridge 86% 94% Rocky Point 96% 98% Bitter Point 100% 99% Seal Beach 90% 91% Westside 94% 96% 2021 Asset Management Plan 121 Table 3-5.

Typically, the break-in percent metric should track closely with the inverse of the proactive maintenance percent as one is a measure of proactive maintenance program and the other a measure of unplanned outages or a reactive maintenance response. However, at Plant No. 1 – Interplant Area for FY19-20, there was an increase in both the proactive maintenance percent and the break-in percent. The data indicate that this is an anomaly due to the low number of work orders for the area. At Plant No. 2, the data show an increase in both metrics in the solids handling facilities. This is simply a reminder that CM work orders that are assigned a high priority are in fact a small percentage of total CM work orders and it is entirely possible to have an increase in both data populations. Literature for the manufacturing industry (SMRP, 2013) indicates that high performers can expect a break-in percent of less than 10%. Break-in percent for Plant No. 1 is shown in Table 3-6 and Plant No. 2 in Table 3-7. Success is measured as a consistent trend downward overtime. Table 3-6 Break-in Percent for Reclamation Plant No. 1 Process Area FY 18/19 FY 19/20 FY 20/21 Preliminary 16% 20% 24% Primary 30% 28% 23% Interplant 0% 16% 7% Activated Sludge 14% 14% 11% Trickling Filters 4% 10% 18% Digesters 38% 20% 27% Solids Handling Facilities 37% 22% 24% Central Power Generation 29% 11% 14% Electrical Distribution 5% 5% 10% Utilities 26% 21% 26% 2021 Asset Management Plan 122 Table 3-7.

Bay Bridge and Lido pump stations both saw an increase in break-in percent. This is reflected in the proactive maintenance percent decrease for those pump stations due to leaking valves, pump ragging, and check valve failures. Table 3-8 Break-in Percent for Pump Stations Process Area FY 18/19 FY 19/20 FY 20/21 ‘A’ Street 12% 4% 6% 15th Street 2% 7% 6% Lido 36% 27% 35% Bay Bridge 11% 18% 31% Rocky Point 20% 4% 7% Bitter Point 9% 14% 14% Seal Beach 27% 14% 20% Westside 3% 7% 3% Edinger 12% 18% 0% Slater 17% 7% 3% College 0% 2% 11% Crystal Cove 5% 32% 6% Yorba Linda 0% 29% 10% Main Street 60% 4% 4% MacArthur 3% 28% 11% 2021 Asset Management Plan 123 Maintenance and Engineering teams work together to find solutions and resolve issues that are identified in the facilities. The teams can respond and react more effectively to resolve urgent issues. This includes a streamlined approach for equipment replacement and contractor support. Engineers work closely with mechanics and electricians to identify issues early and collaborate on solutions. The reduction in break-in or emergency call out work as shown in Figures 3-1 and 3-2 is one example of the impact the Asset Management Program has had on Maintenance and its productivity. Figure 3-1. Electrical Emergency Work Orders Figure 3-2. Mechanical Emergency Work Orders The number of electrical “emergency” work orders and associated hours have reduced more than 3 times during the first 9 months in 2021 compared to the same period in 2020. The mechanical emergency work has decreased more than five times comparing the first two quarters of 2019 to the first two quarters of 2021. 3.2.4 Maintenance Costs and Labor Hours OC San uses the maintenance costs and number of labor hours over time as trend indicators to indicate the amount of resources devoted to reliably maintaining the process areas. The data indicates that there has been a large increase in maintenance costs accompanied by a slight increase in maintenance labor hours in the Treatment Plant No. 1 Solids Handling (Figure 3-3 and Figure 3-4). This is due to high cost to maintain the equipment and contracts with manufactures of the equipment. 0 50 100 150 200 Qtr1 Qtr2 Qtr3 Qtr4 Qtr1 Qtr2 Qtr3 Qtr4 Qtr1 Qtr2 2019 2020 2021 Ho u r s Electrical Emergency Work Orders - Call Back and Overtime Hours Total 0 50 100 150 200 250 Qtr1 Qtr2 Qtr3 Qtr4 Qtr1 Qtr2 Qtr3 Qtr4 Qtr1 Qtr2 2019 2020 2021 Ho u r s Mechanical Emergency Work Orders - Call Back and Overtime Hours Total I 11 11 t.

Figure 3-4. Representative Graph of Maintenance Labor Hours The maintenance cost at Plant No. 2 were higher for FY20/21 for the central generation process because the engines are being rebuilt and higher for the trickling filters because of major equipment failures.

Regarding the Bay Bridge Bay Bridge pump station, there is a large increase in both maintenance costs and labor hours due to emergency replacement of critical valves. This was also noticed with the increase in break-in percent and decrease in the proactive percentage. 3.3 Maintenance Planning OC San uses Maximo as the computerized maintenance management system. All maintenance related activities are stored in Maximo. In short, the information in Maximo makes up OC San’s Maintenance Plan. Maintenance planning primarily consists of PM and PdM work orders. Currently, OC San proactively maintains over 60,000 stored in Maximo. For the assets. associated with process and treatment, there are approximately 4,282 active PM work orders. Approximately 229 of those PMs are related to predictive maintenance activities. A summary and breakdown of the PMs and PdMs are shown on Figure 3-6. Figure 3-6.

This includes non-process related assets such as HVAC equipment, lighting, mobile equipment, etc. 3.3.1 Projected Maintenance Costs The projected maintenance costs over the next two fiscal years in shown in Table 3-9. This accounts for materials and services only but is inclusive of both treatment plants and the collection system. For historical maintenance expenditures, please refer to Chapter 4. Table 3-9. Projected Maintenance Costs Next 2 Fiscal Years FY 21/22 FY 22/23 Projected Maintenance Costs $26.7M $24.2M 3.4 Asset Management Program Accomplishments Another way to measure Asset Management Program performance and success is by exploring the accomplishments. The accomplishments identified in the sections below are important because they focus on both long-term planning and accomplishments that helped extend the useful life of critical assets, increase reliability, reduce unexpected failures and break-ins allowing OC San to meet the key objectives of the Program. 3.4.1 Condition Assessment Program A critical component of the program is the condition assessments performed on a regular basis. The Asset Management Group has completed approximately 50 different condition assessments last fiscal year utilizing an outside consultant and contractor. The assessments included assessing clarifiers, digesters, air and gas piping, primary influent piping, chemical storage tanks, structural assets, manholes, pumpstation wetwells, cathodic protection, and sump pumps to name a few. These assessments identify deficiencies and the general condition, but more importantly recommendations for repairs or replacement and general timing based on RUL estimations. The condition assessments have resulted in the identification of several new projects that are required to keep OC San facilities safe and reliable. 3.4.2 Collection System Assets Our pump stations, force mains and gravity sewer system are vital asset in conveying flow to the treatment plants. The Asset Management Program is continuously evaluating ways to improve resiliency and reliability of the system while maintaining level of service in all flow conditions. Some of the collection system initiatives and accomplishments are identified below. 3.4.2.1 Manhole Inspections In November 2020, OC San started conducting routine inspections of the regional collections system manholes. A total of 855 manholes have been inspected to date since the start of the program. Reports are provided to OC San with asset details as well as defects discovered during the inspection per National Association of Sewer Service Companies (NASSCO) standards. Similar to pipeline CCTV data, OC San has been collating all manhole CCTV inspection data into the Asset Management Program Info Asset Planner for further evaluation and to continue building a comprehensive database of CCTV inspection data. 2021 Asset Management Plan 127 3.4.2.2 Gravity Collections Remaining Useful Life Over the past 2 years, OC San has aggregated all gravity sewer, siphon, air jumper, and manhole data into a single comprehensive Gravity Collections Asset Registry. Data in the asset registry include NASSCO scoring, theoretical RUL, and upcoming projects affecting an asset. In the past year, the entire Gravity Collections system was analyzed in order convert NASSCO scoring into RUL to complete the asset registry. High risk assets were further evaluated by considering the consequence of failure. In short, the Gravity Collections Asset Registry has evolved into a very useful tool for developing, validating, and refining the Asset Management Plan and CIP for the Gravity Collections system. 3.4.2.3 Pump Station Isolation Reliability of the pump stations are critical. In the past, emergency break-in work has been required due to failure of critical assets such as isolation valves at some of the pump stations. With Asset Management Team taking ownership of the pump stations in recent years, OC San is now taking a proactive approach to rehabilitation and repair at the pump stations. For example, approximately seven valve replacement projects have been identified to replace aging or non-functioning pump station valves. The timing of these projects considers risk and criticality to minimize the risk of emergency work. 3.4.3 Central Generation Facility Planning The internal combustion engines at Plant No. 1 and Plant No. 2 have significant run time and need a major overhaul to maintain reliability for the next 10 years or longer. One planning study has evaluated the feasibility of maintaining the engines in the long term (about 20 years), and what work needs to be done to keep the engines reliable for the foreseeable future, while ensuring parts and major components are readily available and that reputable service contractors in the marketplace can perform the necessary overhauls. Another study in the works is an update to the OC San Energy Master Plan that will evaluate viable alternatives for energy production and digester gas management, considering emerging technologies, market conditions and potential permitting constraints with the understanding that OC San’s existing engines are becoming obsolete and increasingly unreliable. The Asset Management Team and Maintenance are working together to ensure OC San has a long-term plan to manage energy use, energy production, and handling of digester gas. 3.4.4 Treatment Plant Project Delivery A major focus of Asset Management Team is streamlining the replacement or repair of our critical plant assets. The Asset Management Team works in tandem with Maintenance to identify projects, provide construction bid documents and manage project implementation of Maintenance Projects. Here are just a few of the projects that have or are close to being completed that were driven by Asset Management and Maintenance Teams: Reclamation Plant No. 1: •Several maintenance projects were implemented to allow Primary Clarifiers 3 and 4 to be available for the 21/22 wet weather season. Final repairs are anticipated to be completed by mid-December 2021. •Through a planned condition assessment of activated sludge reactors at Activated Sludge No. 1 Facility, the RAS piping was found to be severally corroded and at risk of failure. A small project is being implemented to replace corroded piping and pipe supports. •Several of our critical pumping systems are equipped with VFDs that have come obsolete and can no longer be maintained properly. Projects are in place to replace the old VFDs. 2021 Asset Management Plan 128 Treatment Plant No. 2: •The Truck Loading facility at Plant No. 2 was need of mechanical equipment replacement or refurbishment. Several Maintenance managed projects have addressed aging and failed equipment at this facility. •The major process pumps at the Trickling Filter Solids Contact Facility at Plant No. 2 needed major refurbishment due to corrosion and reliability concerns. Over the course of a few years, a total of 18 large capacity vertical turbine pumps were refurbished. •Eleven Plant No. 2 digesters and associated bridges were inspected over past couple years when the tanks were taken out of service for cleaning. Many urgent repairs were performed and new Maintenance projects identified. Asset Management is coordinating all the digester-related projects to assure the projects are successfully executed without disruption to O&M activities. •Three projects were carefully phased and implemented to replace the mechanical mechanisms in all 12 secondary clarifiers at the Plant No. 2 Activated Sludge Facility. •The main sewage pumps at Plant No. 2 required both an overhaul of the motors and a 10-year PM work on the associated VFDs. This important work was carefully sequenced to maintain plant operations and was delivered on time. •Several of our critical pumping systems are equipped with VFDs that have come obsolete and can no longer be maintained properly. Projects are in place to replace the old VFDs. 3.5 Asset Management Program Improvement Opportunities The Asset Management Program continues to evolve with an emphasis on continuous improvement. The foundational elements of the program have been in place for a few years now. The Asset Management Team continues to identify new projects and update the short, medium, and long-term asset management plans to keep OC San assets reliable and available when called upon. Asset Management also continues to support and validate the 20-year CIP. Asset management involves managing lots of data and information. The Asset Engineer considers available information and stakeholder perspectives when making recommendations and estimating asset condition and RUL. The general long-term strategy for the program is to move towards a data-driven program where decisions are made are defensible and work within defined constraints and limitations. The long-term improvement opportunities discussed below must be consistent with OC San strategies and priorities and align with the vision, mission, and key objectives of the program. 3.5.1 Short-to-Medium-Term Improvement Opportunities Condition Assessments: •Improve the condition assessment tracking of our critical assets and have a plan to assess them on a determined frequency. •Track future condition assessments in the Asset Registries and proactively plan ahead with Operations for assessments that require out of service assets. •Take field measurements to better understand how our major civil and mechanical assets degrade (deteriorate) over time allowing more accurate determination of RUL. 2021 Asset Management Plan 129 Remaining Useful Life: •Define RUL such that it is clear RUL typically means replacement or major rehabilitation of an asset or group of assets •Consider the risk and consequence of failure when determining condition scores and RUL and the timing of asset replacement or rehabilitation •Create more condition scoring categories in the 1-10 year range as RUL accuracy improves over time as asset management improves data management and condition scoring guidelines Asset Registries •Ensure all critical assets are being monitored and tracked in the Asset Registries. •Standardize the format and information in the asset registries. Combine them into a single database for consistency and ease of filtering. •Create better alignment with Maximo by ensuring critical assets are clearly defined and asset descriptions are consistent with Maximo. •Allow the asset registries to communicate and pull information with other OC San systems including Maximo and Geographical Information Systems. Asset Hierarchy •Create an OC San asset hierarchy that works for both Maximo and the Asset Registries. •Ensure the level of asset tracking in the Asset Registries is adequate and meets the needs of OC San stakeholders. 3.5.2 Longer-Term Strategy and Improvement Opportunities The OC San Asset Management Program will look to move towards a data-driven program taking advantage of the information, tools, and technologies available to make better decisions and minimize asset life cycle costs. Utilizing available data to the fullest extend and developing a dynamic Asset Management Plan will be key in helping the program be successful in the long term. Some potential long-term strategies include: •Automating and developing real-time dashboards of asset condition based on performance condition assessments •Developing a dynamic risk model to better prioritize maintenance activities and project implementation •Moving towards a dynamic Asset Management Plan where asset health and estimated remaining life are available down the asset level •Prioritizing capital projects and associated spending using both cost and risk based modeling considering constraints and limitations •Creating Key Performance Index (KPI) dashboards to monitor performance and trends and overall program success •Evaluating asset failures to determine maintenance and rehabilitation improvements Long-term strategies will be re-evaluated on a periodic basis as the asset management industry and the needs of OC San evolve. Additional or changes to the program metrics or KPIs are envisioned as we better understand the life cycle cost of our major assets and do our best to 2021 Asset Management Plan 130 “deliver the required level of service, at the lowest life cycle cost, with an acceptable level of risk.” 3.6 Reference Society for Maintenance and Reliability Professionals (SMRP). 2013. Maintenance and Reliability Best Practices. 4th Edition. 2021 Asset Management Plan 131 4 Budgetary Considerations The Asset Management Plan focuses on documenting short- to long-term planning of maintenance and capital improvement projects to support effective budget development and sustainable operations. OC San has been striving to identify more accurate medium- to long- term capital cash flow requirements. Specifically, the Planning Division has been working on developing a 20-year CIP by creating project plans for forecasted rehabilitation, replacement, improvements and expansion for the collection system and treatment plants. The CIP budget is evaluated and updated on an ongoing basis as new information becomes available. 4.1 Capital Improvement Expenditures FY21-22 Budget Update, the second year of the 2-year budget adopted in June 2020, includes updates to the 20-year CIP outlay. Figure 4-1 shows the 20-year CIP outlay, which includes current and projected future CIP projects. FY21-22 CIP outlay is further divided into process categories shown on Figure 4-2.

FROM:James D. Herberg, General Manager Originator: Rob Thompson, Assistant General Manager SUBJECT: SUPERCRITICAL WATER OXIDATION RESEARCH OPPORTUNITY GENERAL MANAGER'S RECOMMENDATION RECOMMENDATION: Recommend to the Board of Directors to: A. Approve a Professional Services Agreement to 374Water Systems, Inc. for the Supercritical Water Oxidation Demonstration at Plant No. 1, Project No. RE21-01, to provide goods and services for demonstration of the 374Water AirSCWO Nix6 System, for an amount not to exceed $5,139,000; and B. Approve contingency funds for Project No. RE21-01 for a combined total not to exceed $514,000 (10%). BACKGROUND The Orange County Sanitation District (OC San) collects and processes 185 million gallons of wastewater every day. Cleaning this water results in concentrated solids called sludge and scum. These energy rich solids are processed through anaerobic digestion to create methane-rich gas and biosolids. The methane-rich gas is cleaned and used in the treatment plants to make electricity and heat. Biosolids are the residual material commonly used in the agricultural industry as a soil amendment. OC San continues to actively pursue management options to maintain a long-term program that promotes beneficial use of biosolids. In accordance with the principles of its biosolids management policy (Resolution No. OCSD 13-03), OC San maintains a diverse portfolio of biosolids management options that utilize multiple contractors, facilities, and product markets, while maintaining fail-safe, back-up options. This portfolio ensures that we have reliable options for managing the material should regulations, market conditions, severe weather, or other situations impact any one management option. Most of OC San’s biosolids are either composted to create a soil amendment or directly applied to agricultural land. Consistent with our policy to maintain diverse biosolids options, staff has been actively researching new and innovative technologies. For example, in July 2021, OC San entered into an Agreement with the Rialto Bioenergy Facility for a pilot project to process up to 100 tons per day of its biosolids in a thermal conversion process. Orange County Sanitation District Printed on 11/23/2021Page 1 of 5 powered by Legistar™ OC6SAN ORANGE COUNTY SANITATION DISTRICT File #:2021-1960 Agenda Date:12/1/2021 Agenda Item No:9. Staff has also been following a new technology for solids treatment for several years that takes advantage of a unique property of water at high temperature and pressure.The technology presents an opportunity to convert all complex organic material (including plastics and PFAS)to more basic and benign compounds like nitrogen, water, carbon dioxide, and mineral salts. A new company,374Water Systems,Inc.(374Water),with a novel,simpler process design,is moving to scale-up the process technology from a one-ton-per-day unit patented and operating at Duke University in North Carolina.Assistant General Manager Rob Thompson witnessed the operation of the unit in North Carolina in May.Staff is in discussions with 374Water to engage in a research program to scale up and operate a six-ton-per-day unit and,if successful,potentially a thirty-ton-per- day unit.These first of their kind units at these flow rates will require testing under real-world wastewater plant conditions.Staff believes it is worth pursuing a demonstration scale project due to the process and mechanical simplicity. It is also important to note that this process will only treat concentrated solids streams,not the entire water flow.Part of the research process will be to document the ability of the system to destroy plastics,PFAS type compounds,and other constituents of emerging concern that can be concentrated in sludge streams.The proposed research/demonstration program would be capable of treating raw primary and secondary sludge, biosolids, and food waste. OC San has a long history of researching new and innovative technologies to improve wastewater treatment and resource recovery.OC San’s budget contains a Master Research Program line item which can be found on page A-9 of the Fiscal Year 2021-22 Budget Update.This line item is the intended funding source for this research opportunity. RELEVANT STANDARDS ·Provide technology leadership to the wastewater industry ·Search for technology solutions to neutralize constituents of emerging concern ·Maintain a culture of improving efficiency PROBLEM OC San’s Biosolids Master Plan,Biosolids Policy,and 2019 Strategic Plan support diversification of biosolids management options including researching new technology.Potential future regulations could target emerging pollutants such as PFAS compounds present at low levels in biosolids and could require treatment or destruction of PFAS in biosolids. PROPOSED SOLUTION In continuing OC San’s course of providing leadership and innovation with the evaluation of emerging technology,staff recommends entering into an Agreement with 374Water to demonstrate the efficacy of the supercritical water oxidation process by procuring and operating an AirSCWO Nix6 Demonstration Unit as part of Project No. RE21-01. Orange County Sanitation District Printed on 11/23/2021Page 2 of 5 powered by Legistar™ File #:2021-1960 Agenda Date:12/1/2021 Agenda Item No:9. TIMING CONCERNS OC San has a unique opportunity to team with 374Water to demonstrate this emerging technology with a six-ton-per-day process unit.As part of the shared commitment with 374Water,the costs for supplying,commissioning,operating,and maintaining this unit are significantly discounted.Initiating this project now will demonstrate OC San’s commitment to this emerging technology and will provide guidance for the planning and implementation of solids treatment processes in the future. RAMIFICATIONS OF NOT TAKING ACTION N/A PRIOR COMMITTEE/BOARD ACTIONS November 2021 - Operations Committee requested additional information regarding this item. July 2021 - Operations Committee Information Item. ADDITIONAL INFORMATION The site and utilities work for this project will be designed by 374Water under this Agreement.The execution of the Public Works site and utilities work will be competitively bid by OC San under a separate procurement. Staff presented a research opportunity to the Operations Committee in November 2021.The Committee discussed the issue in some detail and directed staff to bring back additional information about the commercial terms regarding the opportunity.Staff has continued to work with 374Water to refine and improve the commercial terms to the Agreement to reduce OC San’s risk and improve the reward for investing in this technology. The proposed demonstration scale installation has the potential to solve several challenges facing OC San.These challenges include solids processing costs,air emissions requirements for methane and power generation equipment,and emerging contaminants such as PFAS compounds and microplastics, food waste utilization, and efficient use of OC San’s treatment plant properties. Staff has been working with 374Water and its partners to share the risk and rewards associated with moving from the previous 1-ton per day pilot unit to a 6-ton per day demonstration scale facility (Nix6). The proposed Agreement deal points include: On the risk side of the ledger: ·OC San pays $900K for the sludge preprocessing unit which represents 374Water’s costs with reduced profit for the sub vendor. ·OC San pays a reduced cost for engineering of the facility integration plans. ·OC San will withhold 25%of the equipment cost from the progress payments until the unit Orange County Sanitation District Printed on 11/23/2021Page 3 of 5 powered by Legistar™ File #:2021-1960 Agenda Date:12/1/2021 Agenda Item No:9. ·OC San will withhold 25%of the equipment cost from the progress payments until the unit operates successfully for 1,000 hours. ·OC San pays the anticipated future “mass produced price”of the unit in an amount not to exceed $2.2 million.It is estimated that 374Water’s price for the demonstration unit will be $3.5 million.This provision limits OC San’s risk.374Water plans to invest $1.3 million to develop this first Nix6 unit,but 374Water must invest what is necessary to make the unit functional at no additional cost to OC San. On the reward side of the ledger: ·OC San receives perpetual,royalty free use of the Intellectual Property for all future purchases of Air Supercritical Water Oxidation units from 374Water. ·OC San gets to fully test and understand the ability of the technology to destroy emerging contaminants. ·OC San gets to validate the operations and maintenance costs,opportunities,and limitations of this new technology.This is important for long-term solids processing planning in the future. OC San will be spending hundreds of millions of dollars on solids processing and energy production in the next 20 to 30 years. ·OC San has the opportunity to sell back the Nix6 portion of unit to 374Water for list price.This can be used for a credit toward the purchase of a larger,30-ton-per-day Nix30 upgrade should the demonstration plant work successfully. ·OC San gets the benefit of processing 6 tons per day of solids during the testing cycle.Staff project that the cost for biosolids processing will be roughly equivalent and the cost to treat raw sludge will be $100 per ton more for Air Supercritical Water Oxidation.This is due to the economies of scale in the treatment plant and the unoptimized nature of the initial Nix6 unit. The point of investing to scale up this technology is to position OC San to solve the technical problems it is facing in the long term.Our research program is focused on solving problems faced by our operations. Past research includes: ·An 800kw fuel cell that produced transportation hydrogen from digester gas. ·A sludge cell destruction technology to improve the digestibility of sludge. ·Water scrubbing of Digester Gas. ·Odor control chemical addition techniques (resulted in a Patent). ·Central Generation Engine dual catalyst on digester gas (allowed us to keep our engines). ·Enzyme additions to break up scum blankets. These investments,whether the technology was successful or unsuccessful,have been beneficial in helping to guide our capital program decision-making.The successes and failures are important learning opportunities at a small scale.It is important to keep in mind that OC San makes about 550 wet tons per day of biosolids.Which means that we settle out closer to 1,400 wet tons of raw solids Orange County Sanitation District Printed on 11/23/2021Page 4 of 5 powered by Legistar™ File #:2021-1960 Agenda Date:12/1/2021 Agenda Item No:9. wet tons per day of biosolids.Which means that we settle out closer to 1,400 wet tons of raw solids that are sent to our digesters.Learning at small,demonstration scale and scaling up is critical to managing risk,rather than jumping into a full-scale installation.Some technologies fail initial small- scale testing, some fail scaling-up, and some deliver in ways never expected. At the November 2021 Operations Committee meeting,staff was asked to look into potentially negotiating an equity stake in 374Water to share in future revenues,should the demonstration scale facility prove successful.Looking into this possibility,staff found that some public utilities have established a separate corporation to retain an equity stake in private ventures.OC San has not established such an entity and moving into this presents a public agency like OC San with several challenges.This will require significant legal analysis to form a final opinion,which has not yet been done. In addition,there may be limited value for pursuing this complicated commercial relationship since the underlining patented technology is owned by Duke University with 374Water licensing and selling packaged Nix6 units.374Water has agreed to pay all licensing fees and provide any developed intellectual property to OC San for free on all future Air Supercritical Water Oxidation purchases. CEQA The project is exempt from CEQA under the Class 6 categorical exemptions set forth in California Code of Regulations Section 15306.A Notice of Exemption will be filed with the OC Clerk-Recorder after OC San Board approval of the Professional Services Agreement. FINANCIAL CONSIDERATIONS This request complies with authority levels of the OC San Purchasing Ordinance.This item will be funded through the Research Program (M-RESEARCH)and has been budgeted.(FY2021-22 Update, Appendix A, Page A-9).

PSA PROJECT NO. RE21-01 Revised 062821 SUPERCRITICAL WATER OXIDATION DEMONSTRATION AT PLANT No. 1 Page 20 of 24 Exceptions (A) through (B) above shall not apply, and CONSULTANT shall, to the fullest extent permitted by law, indemnify the Indemnified Parties, from Claims arising from more than one cause if any such cause taken alone would otherwise result in the obligation to indemnify hereunder. CONSULTANT’s liability for indemnification hereunder is in addition to any liability CONSULTANT may have to OC SAN for a breach by CONSULTANT of any of the provisions of this Agreement. Under no circumstances shall the insurance requirements and limits set forth in this Agreement be construed to limit CONSULTANT’s indemnification obligation or other liability hereunder. The terms of this Agreement are contractual and the result of negotiation between the parties hereto. Accordingly, any rule of construction of contracts (including, without limitation, California Civil Code Section 1654) that ambiguities are to be construed against the drafting party, shall not be employed in the interpretation of this Agreement. 23. DUTY TO DEFEND The duty to defend hereunder is wholly independent of and separate from the duty to indemnify and such duty to defend shall exist regardless of any ultimate liability of CONSULTANT and shall be consistent with Civil Code Section 2782.8. Such defense obligation shall arise immediately upon presentation of a Claim by any person if, without regard to the merit of the Claim, such Claim could potentially result in an obligation to indemnify one or more Indemnified Parties, and upon written notice of such Claim being provided to CONSULTANT. Payment to CONSULTANT by any Indemnified Party or the payment or advance of defense costs by any Indemnified Party shall not be a condition precedent to enforcing such Indemnified Party’s rights to indemnification hereunder. In the event a final judgment, arbitration, award, order, settlement, or other final resolution expressly determines that the claim did not arise out of, pertain to, or relate to the negligence, recklessness, or willful misconduct of the CONSULTANT, to any extent, then OC SAN will reimburse CONSULTANT for the reasonable costs of defending the Indemnified Parties against such claims. CONSULTANT’s indemnification obligation hereunder shall survive the expiration or earlier termination of this Agreement until such time as action against the Indemnified Parties for such matter indemnified hereunder is fully and finally barred by the applicable statute of limitations. 24. LIMITATION OF LIABILITY Except for CONSULTANT’s obligations to indemnify and defend OC SAN for personal injury, bodily injury and property damage to the extent otherwise required by this Agreement, the CONSULTANT’s total liability to OC SAN arising out of or in connection with this Agreement shall not exceed 300% value of the AirSCWO NIX6 UNIT as stated in Attachment “E”.

Figure 1 is a diagram of the process flow of the complete system. The “System” consists of: (1) Dewatering Unit, (2) AirSCWO Nix6 unit, (3) minerals separation, (4) odor control system, (5) control system and Internet connection, (6) supplementary fuel supply and storage tank, (7) water storage tanks, (8) compressor (with sound attenuation as appropriate) and (9) all connections to equipment, interconnection piping and wiring, and appurtenances physically made by 374Water and excluding all connections made by others during the site work. Plant sludges will be fed to the Dewatering Unit, which will screen out undesirable materials, equalize the two feed streams, and dewater the equalized stream to 12-15% total solids (TS). The resultant stream will be fed to the AirSCWO Nix6 unit where the streams will be treated via supercritical water oxidation resulting in air emissions, distilled water, clean water (treated), and minerals. Distilled water will be stored in a tank and fed back to the AirSCWO Nix6 unit for use in the process. The treated water and minerals will feed into a cone bottom tank and then be discharged to the centrate pipeline. Further description of each of the three units follows below including a description of support infrastructure. All lockout/tagout at sludge, plant water, and electrical points of connection shall be performed jointly by CONSULTANT and OC SAN. Figure 1.

This task is Hazen Task 2.5 in Attachment A-1-A. ATTACHMENT A - SCOPE OF WORK 8 SECTION A-2. SYSTEM Task 4 - Fabrication and delivery of the Nix6 unit, Dewatering Unit, and ancillary equipment including the minerals separation tank 374Water and the Merrell Bros. will fabricate the Dewatering Unit and an AirSCWO Nix6 unit at the Merrell Bros. facility in Kokomo, IN. The Dewatering Unit and Nix6 unit will be delivered to OC SAN following completion of fabrication and FAT. Details are provided below. DEWATERING UNIT The dewatering unit (the “DU” or the “Dewatering Unit”) is designed to condition the liquid waste streams produced by OC SAN in preparation for AirSCWO treatment. The DU is an enclosed 40’ x 8’ x 9.5’ cargo shipping container that is fully integrated with the AirSCWO Nix6, and it has been designed for future integration and use with an AirSCWO Nix30. The container will have large cargo doors to allow access for maintenance and repairs. The process begins with three flange connections on the exterior of the DU where the 5%-7% TS combined thickened sludge and the 2%-3% anaerobic digested sludge feed lines will be connected. The third flange is available for alternate feed stocks for future testing. Also, on the exterior of the container will be a flange to be connected to the OC SAN plant water system. OC SAN will provide power to the DU and the Nix6 unit. Two (2) 3 Phase 480 Volt 200-amp electrical service will be connected to a properly sized disconnect on the exterior of the DU. Figures 5 and 6 illustrate the internal layout of the Dewatering Unit. Figure 5. Side view of the Dewatering Unit ATTACHMENT A - SCOPE OF WORK 9 Figure 6. Angled view of the Dewatering Unit As the liquid feed sludge enters the DU piping manifold, it will travel through a series of valves before entering the inline macerator. The macerator is set in line with a rotary lobe sludge pump that will pump the liquid sludge through a Huber STRAINPRESS® to screen any debris larger than 4mm. The screened liquid sludge from the discharge side of the Huber STRAINPRESS® will flow into an Equalization (EQ) Tank. A submersible electric mixer will equalize the liquid sludge in the EQ tank prior to dewatering. The screening from the Huber STRAINPRESS® will be discharged into an endless bagging system that will go into a small dumpster that is stored inside the DU. A small cargo door will allow for the dumpster to be removed from the DU and properly disposed of. Access will be provided from the road to remove the dumpster. Screenings disposal service will be provided by OC SAN for the 12 months of operation. The next phase of the process is sludge dewatering utilizing a MiValt MD-402 Screw Press. A rotary lobe sludge pump will pull the screened liquid sludge from the EQ tank and feed the Screw Press at the proper flow rate. Included on the DU is an emulsion polymer make-down system with a 2300-pound polymer storage tote. 374Water will provide up to 5680 pounds of polymer, the supply for 12 months of operation. OC SAN will call the supplier for delivery during OC SAN’s 6 month of operation. The made-down polymer will be injected into the sludge as it enters the Screw Press. The Screw Press will be adjusted to produce a 12%-15% Total Solids Cake that will discharge into the sludge Feed Hopper (FH). The filtrate water from the Screw Press will flow into a centrifugal pump that will discharge the filtrate water to the OC SAN centrate line. The FH will have a live bottom screw conveyor system to move the cake sludge to the discharge that will feed the final sludge pump in the process that will feed the Nix 6 or Nix 30 unit. The DU will receive the mineral water that is produced from the SCWO process and discharge it into the filtrate pumping system. To mitigate the risk of odor, the DU is designed to operate under a negative vacuum with fresh air entering the DU, and the exhaust air is designed to be treated with an activated carbon odor control system. The carbon odor control system will be sized for 12 months ATTACHMENT A - SCOPE OF WORK 10 of treatment. 374Water will meet the permit requirements and OC SAN will provide required permit monitoring equipment and data logging. Atmospheric monitoring equipment will be installed in the DU. The control system from the DU and SCWO units will be fully integrated to allow for simple and efficient operations. OC SAN will, at its expense, provide an office trailer for the operator. 374Water will provide remote monitoring services and process support through an internet service provider. The DU will also include exterior lighting for safety. Internet service will be provided at 374Water’s expense for 12 months. AirSCWO Nix6 Unit The AirSCWO Nix6 will be contained in a 40-foot cargo container. The inlet waste stream is continuously fed to a heat exchanger to preheat the stream before entering the reactor. The stream is then combined with compressed air from a high-pressure compressor. The air and water at high pressure and temperature oxidize the organics in the reactor to clean water, inert gases, mineral salts, and heat. The heat is recycled to heat-up the inlet waste stream in the economizer and to flash some of the effluent, together with the high-pressure exhaust gases, in the expander to produce mechanical power to run the air compressor. The effluent water with the suspended minerals is cooled, depressurized, and safely discharged from the system. The water and mineral salts are separated. Figure 7 illustrates the inflows and outflows of the AirSCWO Nix6 unit. Figure 7. AirSCWO Nix6 inflows and outflows Mineral separation The AirSCWO unit will produce a mineral stream consisting of oxidized minerals suspended in water. This stream will be routed to a pump on the Dewatering Unit and ATTACHMENT A - SCOPE OF WORK 11 then pumped to the central line along with other process waste streams for disposal to the OC SAN centrate line. A minerals sampling/separation unit will also be provided to allow a portion of the minerals stream to be retained for testing. The minerals separation unit will consist of a cone bottom settling tank (Figure 8) and associated piping and valves to allow flow to be routed from the AirSCWO Nix6 unit to the settling tank, and to allow settled minerals to be captured for analysis. Decanted water from the settling tank will be routed to the Dewatering Unit for disposal along with other process waste streams. Mineral separation unit and sampling area will be set on secondary containment to maintain clean surroundings. Figure 8. Representative cone bottom tank for minerals separation. Factory Acceptance Testing (FAT) A FAT will be performed upon fabrication completion of the Dewatering and AirSCWO Nix6 units. The Dewatering and AirSCWO Nix 6 units may be interconnected or tested separately, and pressure tested. The FAT shall test each unit using sludge and the AirSCWO Nix6 using a fuel source. The FAT shall demonstrate that the system successfully operates for 48 continuous hours. ATTACHMENT A - SCOPE OF WORK 12 SECTION A-3. INSTALLATION, OPERATIONS, MAINTENANCE, AND TRAINNG SERVICES CONSULTANT’S obligation to commence the services set forth in this Attachment A-3 shall be contingent upon OC SAN’s completion of the SITE WORK in accordance with the design, drawings, and specifications provided to OC SAN under the DESIGN SERVICES. Task 5. Physical site integration of the systems at OC SAN Plant No. 1 374Water will install the System at OC SAN. The DU and AirSCWO Nix6 units will be placed on site promptly following the final completion of the site work in accordance with the design drawings and specifications, including the installation of support infrastructure, as validated by 374Water. 374Water will connect the DU to the OC SAN pipeline that will convey combined thickened sludge (CTS) and digested sludge (DS) for processing. A piping connection will also be provided to allow alternative test materials, such as food waste, to be pumped into the system. The DU will be connected to an OC SAN plant water line. 374Water will connect the DU and AirSCWO Nix6 units and connect the AirSCWO Nix6 outlet lines to the Minerals Separation Tank and the OC SAN centrate drain line. 374Water will also connect the DU unit to the odor control unit. OC SAN will connect two 200A 480v electrical services from the existing 480V Motor Control Center – 15LMCC294 (MCC-SHF) in its Thickening & Dewatering Facility – Electrical building to the DU unit. 374Water will make the electrical connections within the System. A power monitor will be installed at the MCC as part of the SITE WORK for each service line and will record amperes, kW and KVA.

Hazen and Sawyer 800 W. 6th Street., Suite 400 Los Angeles, CA, 90017 ATTACHMENT A-1-A I. SUMMARY Services in this scope of work will generally be in two efforts: 1. Pre-Design, Design and Permitting Support 2. Construction, Installation and Close Out Support II. PROJECT ELEMENTS DESCRIPTION – SITE PREPARATION FOR DEMONSTRATION TREATMENT FACILITYSYSTEM This project element includes the development of a site layout plan for the Demonstration Treatment System (System). The location for the System has been identified as the gravel paved area adjacent to the Plant No. 1 Eastern fence line. Hazen will develop a site layout including the location of the Treatment Unit, Dewatering Unit, mineral separation unit, office trailer, mobile toilet, storage container and odor control unit. The layout will be arranged to avoid putting heavy treatment units on top of the existing high pressure gas pipeline. Hazen will utilize a sub consultant to conduct a topographical survey of the site location. Hazen will prepare a grading plan for area. It is anticipated that some minor regrading of the existing site will be necessary to prepare level sites for treatment units but that import or removal of material will not be required. Hazen will utilize a sub consultant to conduct a desktop geotechnical evaluation of the site and will develop recommendations for seismic anchorage of the treatment units. The System will require connections to the existing combined thickened sludge, dewatered sludge, centrate and plant water lines located on the pipe rack on the eastern edge of the site. Hazen will prepare a design for these piped connections. The System will require two 200 A 480V 3P electrical supplies. OC SAN has identified an existing motor control center in the Thickening & Dewatering System – Electrical building which has capability to provide these electrical supplies. Hazen will design cabling and conduit to route power from this MCC to the dewatering unit. Hazen will also design cabling and conduit to route power from the dewatering unit to the AirSCWO Nix6, office trailer and the odor control unit. All other site power distribution will be provided as part of the dewatering and treatment units. The System will have the capability to send select hardwired alarm and monitoring signals to the OC SAN control system. Hazen will design cabling and conduit to route these Hazen Page 2 of 15 signals from the dewatering unit to an existing PLC or RIO located in the Thickening & Dewatering System. The System will include a packaged activated carbon odor control unit to treat foul air from the Dewatering Unit. Hazen will prepare a specification for this unit, which will be procured and installed as part of Section A-2 of Attachment “A”. The unit will be specified to require carbon changeout at intervals of 1 year or more. Hazen will also design the duct to connect the dewatering unit to the odor control unit. To facilitate construction of the System the centrate pipes will be modified to include additional pipe connections to allow the two centrate lines to be drained when not in use. A location for these drainage connections has been identified in Tunnel 29. Assumptions For the design level of effort, Hazen has assumed the following: The geotechnical evaluation will be based on existing geotechnical information provided by OC SAN. No ground investigation will be conducted Electrical supplies will come from existing motor control centers, no MCC design will be required Instrumentation connection will be to an existing PLC or RIO; other than cabling and conduit no new equipment will need to be specified IV.

FROM:James D. Herberg, General Manager Originator: Kathy Millea, Director of Engineering SUBJECT: OCEAN OUTFALL CONDITION ASSESSMENT AND SCOPING STUDY, PROJECT NO. PS18-09 GENERAL MANAGER'S RECOMMENDATION RECOMMENDATION: Recommend to the Board of Directors to: Approve a contingency increase of $823,200 (30%) to the Professional Services Agreement with Carollo Engineers, Inc. for Ocean Outfall Condition Assessment and Scoping Study, Project No. PS18-09, for a total contingency of $1,097,600 (40%). BACKGROUND The Ocean Outfall Condition Assessment and Scoping Study is completing a condition assessment of the 120-inch outfall that discharges effluent from the Orange County Sanitation District (OC San) Plant No. 2, approximately five miles off the coast of Huntington Beach. The condition assessment included an internal inspection and external inspection by divers, and development of a 3D model of the outfall using both internal and external mapping. The internal inspection and mapping are complete, and the external inspection and mapping are partially complete with the outstanding work being the removal and replacement of one manhole cover on the outfall to determine the condition of the material, and the 3D mapping. RELEVANT STANDARDS ·Protect OC San assets ·24/7/365 treatment plant reliability PROBLEM On the morning of October 4, 2021, OC San was scheduled to begin work to determine the condition of the existing manhole covers on the outfall. This work involved sending a specialized dive team to the ocean floor to remove and replace the last manhole cover on the outfall pipe, so the existing manhole cover could be brought to the surface for testing. This work was planned months in advance but had to be called off due to the oil spill. The project incurred mobilization and demobilization costs due to having to cancel the work. In addition, the condition assessment has revealed that there are several elements of the outfall Orange County Sanitation District Printed on 11/23/2021Page 1 of 3 powered by Legistar™ OC6SAN ORANGE COUNTY SANITATION DISTRICT File #:2021-1977 Agenda Date:12/1/2021 Agenda Item No:10. In addition,the condition assessment has revealed that there are several elements of the outfall requiring immediate repair to ensure the outfall continues to function as designed.These repairs include replacing the metal tie-rods connecting joints in the outfall pipe,and cracks in the concrete and metal end gate.If the tie rods are not replaced,a flow surge could cause the joints to separate. If the concrete cracks are left untreated,they could allow the salt water to migrate to the rebar in the pipe leading to corrosion.If the cracked end gate is not repaired,a leak could develop at the end structure. PROPOSED SOLUTION Increase the contract contingency to cover: 1)Project costs incurred due to mobilizing and canceling the dive team because of the October 4,2021 oil spill.OC San will work with legal counsel to seek reimbursement for additional costs associated with the oil spill. ($155,503) 2)Urgent outfall repairs to be conducted while the dive team is still under contract,including tie- rod replacement, concrete crack repairs, and metal end gate repairs. ($671,882) TIMING CONCERNS This work needs to be completed as soon as possible.OC San would like to reschedule the manhole cover removal and replacement work for April 2022 after the wet weather season.The crack repair and tie rod replacement can occur during that same mobilization.However,the dive team will need to take detailed measurements of the tie rods before April so the tie rod replacement parts can be manufactured and be available for installation in April. RAMIFICATIONS OF NOT TAKING ACTION The outfall joints do not have the extra protection from separating during a flow surge that the tie rods provide until they are replaced.Not repairing the cracks could lead to premature concrete corrosion. Not repairing the cracks on the flap gate can lead to leakage through the gate. PRIOR COMMITTEE/BOARD ACTIONS March 2020 -Approved Professional Services Agreement with Carollo Engineers,Inc.to provide engineering services for the Ocean Outfall Condition Assessment and Scoping Study,Project No. PS18-09, for an amount not to exceed $2,744,000; and approved a contingency of $274,400 (10%).

FROM:James D. Herberg, General Manager Originator: Kathy Millea, Director of Engineering SUBJECT: REGIONAL URBAN RUNOFF DIVERSION OPTIMIZATION STUDY GENERAL MANAGER'S RECOMMENDATION RECOMMENDATION: Information Item. BACKGROUND The Orange County Sanitation District (OC San) accepts dry weather urban runoff flows from local agencies to improve water quality at beaches and Newport Bay. OC San’s Dry Weather Urban Runoff Diversion Program allows the diversion of up to 10 million gallons per day (MGD) of dry weather urban runoff. OC San has issued 21 Dry Weather Urban Runoff Permits with a total capacity of 6 MGD. These diversions are owned and operated by local agencies, including the City of Huntington Beach, the City of Newport Beach, OC Public Works, and Irvine Ranch Water District. In addition to improving water quality, another potential benefit is increased water availability for recycling. This additional flow may be needed should future wastewater flows decrease due to more stringent indoor water conservation standards. Reduced wastewater flows could free up system capacity both in the OC San collection and treatment systems to accept additional urban runoff diversions. It is critical that diversions of urban runoff do not cause operational problems in the collection system or treatment plants. The program is carefully managed under a permit-based system that regulates the volume and quality of runoff being diverted into the collection system to prevent spills, treatment process upsets, ocean discharge permit violations, biosolids contamination, or impacts to the Groundwater Replenishment System. RELEVANT STANDARDS ·Comply with environmental permit requirements ·Maintain collaborative and cooperative relationships with regulators, stakeholders, and neighboring communities ·Meet volume and water quality needs for the GWRS Orange County Sanitation District Printed on 11/23/2021Page 1 of 2 powered by Legistar™ OC6SAN ORANGE COUNTY SANITATION DISTRICT File #:2021-1953 Agenda Date:12/1/2021 Agenda Item No:11. PROBLEM OC Public Works must address water quality impacts caused by urban runoff under Municipal Separate Storm Sewer System (MS4)regulatory requirements.In addition,OCWD may need additional flows for GWRS in the future due to reduced wastewater flows at OC San.These problems and OC San’s capacity to accept additional urban runoff flows have not been comprehensively studied. PROPOSED SOLUTION Collaborate with OCWD and OC Public Works to conduct a comprehensive engineering study to identify feasible opportunities for OC San and OCWD to accept additional dry and wet weather runoffs within the existing capacities of both agencies’ infrastructure.
