FROM:Robert Thompson, General Manager Originator: Mike Dorman, Director of Engineering SUBJECT: ENGINEERING PROGRAM CONTRACT PERFORMANCE REPORT GENERAL MANAGER'S RECOMMENDATION RECOMMENDATION: Recommend to the Board of Directors to: Receive and file the Engineering Program Contract Performance Report for the period ending September 30, 2024. BACKGROUND The Engineering Program involves awarding and managing multiple construction and consulting contracts.In 2008,the Orange County Sanitation District (OC San)Board of Directors began authorizing contingencies along with construction and consulting contracts,allowing the General Manager to approve construction change orders and amendments to consulting contracts up to the amount of the authorized contingency.This practice reduces administrative costs,expedites resolution of project issues that arise,helps avoid contractor delay claims,and facilitates efficient management of many contracts. The Engineering Program Contract Performance Report summarizes construction and consulting contract performance and activities for the quarter ending September 30,2024.This report is updated quarterly and includes a summary of the General Manager approved contract contingencies among other key performance indicators. ATTACHMENT The following attachment(s)may be viewed on-line at the OC San website (www.ocsan.gov)with the complete agenda package: ·Engineering Program Contract Performance Report for the period ending September 30, 2024 MD:lb Orange County Sanitation District Printed on 11/26/2024Page 1 of 1 powered by Legistar™ Engineering Program Contract Performance Report For the Period Ending September 30, 2024 1 DATE: December 04, 2024 TO: Orange County Sanitation District Board of Directors FROM: Rob Thompson, General Manager Through: Mike Dorman, Director of Engineering This report summarizes the status, activities, and performance of construction contracts and consultant agreements. This report also identifies the names and status of projects being performed under master budgets for planning studies, research, small construction projects, Operations & Maintenance capital projects and information technology projects. As of September 30, 2024, Orange County Sanitation District (OC San) Engineering Department manages 138 active projects, with project budgeting totaling close to $3.8 billion. These projects are in various project phases, ranging from Project Development to Closeout. The graphic below shows the number of projects in each of the project phases. This report is organized into six parts, as follows. Detailed tables can be found in the appendix section of the report. Part 1 – Construction Contracts .................................................................................................... 2 Part 2 – Engineering Professional Services Agreements ............................................................. 4 Part 3 – Master Budget Projects ................................................................................................... 6 Part 4 – Supplemental Engineering Services Contract ................................................................. 7 Part 5 – Programming Professional Services Contract ................................................................. 9 Part 6 – On-Call Services Agreements ....................................................................................... 11 Engineering Program Contract Performance Report For the Period Ending September 30, 2024 2 PART 1 – CONSTRUCTION CONTRACTS Construction Contracts As shown in the graph below, there are currently 53 active construction contracts totaling $848 million. The graph also categorizes the active construction contracts by project type (plant, collections, and other) with the “Other” category capturing research and small capital projects. Table 1 in the appendix lists the Board-awarded construction contracts while Tables 2 and 3 list the Operations Committee and General Manager awarded construction contracts, active as of September 30, 2024. The General Manager may award contracts up to $150,000 and task orders up to $500,000. The table below summarizes the number of active and closed construction contracts and total contract amounts. See Tables 4, 5 and 6 in the appendix for a list of the closed contracts. Type Contracts Total Contract Amount Active Board-Awarded Construction Contracts 47 $846,101,203 Active Ops Committee Awarded Construction Contracts 2 $318,815 Active GM Awarded Construction Contracts 4 $3,648,850 Closed Board-Awarded Construction Contracts 1 $1,953,454 Closed Committee-Awarded Construction Contracts 0 $0 Closed GM Awarded Construction Contracts 0 $0 Plant Projects 42 Contracts Collection Projects 10 Contracts Other 1 Contracts $31 Million $659 Million $1 Million 35 Unique Contractors Engineering Program Contract Performance Report For the Period Ending September 30, 2024 3 Cumulative Change Order Rates When the OC San Board of Directors awards a construction contract, they also approve a contingency which allows the General Manager to approve contract change orders up to the amount of the contingency. One purpose of this report is to document how much of the contingency is utilized. A contract’s change order rate is only meaningful when the work is completed. As such, this report's change order performance charts are based only on contracts closed since the Board began approving contingencies in 2008. The following chart shows how cumulative change order rates have changed for plant, collections, and all contracts over the past 15 years. Change Order Goals Project Type 15-Year Sliding Window Change Order Goal Plant – New 5% Plant – Rehab 8% Collections 10% Engineering Program Contract Performance Report For the Period Ending September 30, 2024 4 PART 2 – ENGINEERING PROFESSIONAL SERVICES AGREEMENTS Professional Design and Related Service Agreements OC San engages engineering consultants through Professional Service Agreements (PSAs), Professional Design Services Agreements (PDSAs), and Professional Construction Services Agreements (PCSAs). PDSAs are used to obtain design engineering services, and PCSAs are a subsequent agreement with the design consultant to provide support services during construction. PSAs are used for planning studies and other consultant assignments. There are currently 50 Professional Design and Related Service Agreements (26 individual firms) with total agreement amount of $233,456,511. Table 7 in the appendix provides a detailed list of Professional Design and Related Service Agreements. Master Agreements Master Agreements are issued to a pool of pre-qualified consultants for smaller projects. On those smaller projects, OC San solicits task order proposals from interested firms and awards a task order to the most qualified consultant. The Master Agreements are listed below. • 2017 Master Agreements for Planning Studies (expired) • 2018 Master Professional Design Services Agreements (expired) • 2020 Master Agreements for On-Call Planning Studies (expired) • 2021 Master Professional Design Services Agreements (expired) • 2024 Master Agreements for On-Call Planning Studies • 2024 Master Professional Design Service Agreements • Agreement for Design Installation, Implementation and Maintenance of a Process Control System New task orders cannot be issued under expired agreements, but previously issued task orders remain active until completed. Task Orders are limited by OC San Ordinance No. OC SAN-61 to $500,000 per task order. Below is a summary of the various master agreements with active task orders. See Table 8 in the appendix for a detailed list of task orders.

FROM:Robert Thompson, General Manager Originator: Mike Dorman, Director of Engineering SUBJECT: PLATFORM MODIFICATIONS FOR PROCESS AREAS AT PLANT NO.1 AND NO.2,PROJECT NO. FE22-01 GENERAL MANAGER'S RECOMMENDATION RECOMMENDATION: Recommend to the Board of Directors to: A. Receive and file Bid Tabulation and Recommendation for Platform Modifications for Process Areas at Plant No. 1 and No. 2, Project No. FE22-01; B.Award a Construction Contract Agreement to Tharsos, Inc., for Platform Modifications for Process Areas at Plant No. 1 and No. 2, Project No. FE22-01, for a total amount not to exceed $494,494; and C. Approve a contingency of $74,174 (15%). BACKGROUND The Orange County Sanitation District (OC San)operates facilities that manage wastewater, biosolids,and screened waste.These include the Steve Anderson Lift Station (SALS),the Solids Storage Facility at Plant No.1,and the Screenings Loading Building at Plant No.2.These facilities rely on pumps to move wastewater and solids through the treatment process.To ensure they function reliably, regular inspections and routine maintenance are necessary. RELEVANT STANDARDS ·Comply with California Public Contract Code Section 20103.8,award construction contract to lowest responsive, responsible bidder ·Commitment to safety & reducing risk in all operations PROBLEM Several safety concerns are making it difficult for staff to perform routine maintenance effectively and safely.In the SALS,the pumps are positioned on concrete pedestals that are difficult to access. These pedestals lack guardrails and tie-off points,which poses a fall hazard for staff performing maintenance.In the Solids Storage Building,a cake pump is located directly under the motor and gearbox,blocking access to the area,and preventing staff from using step ladders to reach the Orange County Sanitation District Printed on 11/26/2024Page 1 of 3 powered by Legistar™ File #:2023-3246 Agenda Date:12/4/2024 Agenda Item No:3. gearbox,blocking access to the area,and preventing staff from using step ladders to reach the equipment safely.In the Screenings Loading Building,staff are forced to step on the handrail rungs to reach and clear the screenings conveyor belt.This unsafe practice complicates maintenance and increases the risk of injury. PROPOSED SOLUTION Award a Construction Contract Agreement for Platform Modifications for Process Areas at Plant No.1 and No.2,Project No.FE22-01.This project will improve maintenance access at SALS,the Solids Storage Building,and the Screenings Loading Building and install an overhead monorail beam in the Screenings Loading Building. Due to the relatively small construction value,staff recommends a contingency of 15%.If an unknown condition is encountered and there is insufficient contingency,contract completion could be significantly delayed and expose OC San to extended overhead costs by the contractor. TIMING CONCERNS The timely approval of this contract will help ensure hard to reach areas for inspection and maintenance will be improved as soon as possible to maintain a safe work environment. RAMIFICATIONS OF NOT TAKING ACTION If no action is taken,operations and maintenance staff will continue maintaining the existing equipment with unsafe, restricted access.

FROM:Robert Thompson, General Manager Originator: Mike Dorman, Director of Engineering SUBJECT: NEWHOPE-PLACENTIA SEWER MANHOLE REPLACEMENTS, PROJECT NO. FE21-08 GENERAL MANAGER'S RECOMMENDATION RECOMMENDATION: Recommend to the Board of Directors to: A. Receive and file Bid Tabulation and Recommendation for Newhope-Placentia Sewer Manhole Replacements, Project No. FE21-08; B. Award a Construction Contract Agreement to Sancon Technologies, Inc., for Newhope- Placentia Sewer Manhole Replacements, Project No. FE21-08, for a total amount not to exceed $406,730; and C. Approve a contingency of $81,346 (20%). BACKGROUND The Orange County Sanitation District (OC San)operates an extensive network of sewer infrastructure,and as part of its ongoing maintenance and modernization efforts,three manholes in the Newhope-Placentia Trunk Sewer (NHP)system were identified for potential replacement. Originally constructed in 1958,these manholes had sustained significant deterioration due to hydrogen sulfide corrosion,a common issue in wastewater systems.However,after a more detailed evaluation,it was determined that rather than full replacement,the manholes could be rehabilitated to meet modern standards and extend their functional lifespan. RELEVANT STANDARDS ·Comply with California Public Contract Code Section 20103.8,award construction contract to lowest responsive, responsible bidder ·Commitment to safety & reducing risk in all operations PROBLEM Three NHP manholes are severely corroded.Hydrogen sulfide corrosion has eroded the concrete extensively, leaving the reinforcing rebar exposed. Orange County Sanitation District Printed on 11/25/2024Page 1 of 3 powered by Legistar™ File #:2024-3417 Agenda Date:12/4/2024 Agenda Item No:4. PROPOSED SOLUTION Award a construction contract agreement for Newhope-Placentia Sewer Manhole Replacements, Project No.FE21-08.This project will rehabilitate the three manholes to extend their service life ranging between 25 to 50 years depending on the rehabilitation approach. A 20%contingency is requested due to the higher level of risk associated with concrete repair and unforeseen conditions.If an unknown condition is encountered and there is insufficient contingency, contract completion could be significantly delayed and expose OC San to extended overhead costs by the contractor. TIMING CONCERNS The manholes are in an advanced state of degradation and continue to corrode over time.Timely approval of this contract will allow for prompt rehabilitation,helping to ensure the trunk sewer remains safe and fully operational. RAMIFICATIONS OF NOT TAKING ACTION If no action is taken,the manholes will continue to deteriorate,increasing the risk of requiring full replacement at a significantly higher cost and impact to OC San. PRIOR COMMITTEE/BOARD ACTIONS N/A ADDITIONAL INFORMATION OC San advertised Project No.FE21-08 for bids on August 14,2024,and four sealed bids were received on October 9, 2024.

If CONTRACTOR maintains higher limits than the minimums shown in this Section, OC SAN requires and shall be entitled to coverage for the higher limits maintained by the CONTRACTOR.

FROM:Robert Thompson, General Manager Originator: Riaz Moinuddin, Director of Operations & Maintenance SUBJECT: INSTALLATION AND DISPOSAL OF ACTIVATED CARBON MEDIA FOR PLANT NO.1 AND PLANT NO. 2 CENTRAL GENERATION FACILITIES, SPECIFICATION NO. S-2024-648BD GENERAL MANAGER'S RECOMMENDATION RECOMMENDATION: Recommend to the Board of Directors to: A. Approve a General Services Contract to MP Environmental Services, Inc. to install and dispose of activated carbon media for Plant No. 1 Co-Gen and Plant No. 2 Central Generation (CenGen) facilities, Specification No. S-2024-648BD, for a total amount not to exceed $713,880 for the period beginning January 1, 2025, through December 31, 2025, with four (4) one-year renewal options; and B. Approve an annual contingency of $71,388 (10%). BACKGROUND The Orange County Sanitation District (OC San)Plant Nos.1 and 2 CenGen facilities use granular activated carbon to remove siloxane,volatile organic carbon,and sulfur compounds from digester gas.Removing these compounds is necessary to meet air compliance standards,maintenance requirements,and protect emissions catalysts.Failure to remove these compounds will quickly damage both the reduction and oxidation catalysts required for controlling engine emissions. At Plant No.1,two vessels are used in series and three vessels are used at Plant No.2.The first vessel serves as the primary tank for roughing and the second vessel is used for polishing the residual compounds from the biogas.The third vessel at Plant No.2 is used as a standby.Each vessel has three layers of activated carbon media with different specifications recommended by the system manufacturer to target specific components in the biogas. RELEVANT STANDARDS ·Maintain a proactive asset management program ·24/7/365 treatment plant reliability ·Protect OC San assets Orange County Sanitation District Printed on 11/26/2024Page 1 of 3 powered by Legistar™ File #:2024-3959 Agenda Date:12/4/2024 Agenda Item No:5. PROBLEM The carbon media used for combustion in the CenGen facilities have limited capacity to absorb pollutants.Once the carbon material is saturated,the medium is exhausted and must be replaced to comply with SCAQMD permits and operational requirements. PROPOSED SOLUTION Staff recommends approval of a General Services contract with MP Environmental Services,Inc.to remove and replace the carbon media utilized to clean digester gas at Plant Nos.1 and 2 CenGen facilities. TIMING CONCERNS When the carbon media in the biogas cleaning system becomes exhausted,contaminants break through,leading to emissions catalyst failure at the CenGen facilities.As a result,the engines will be unable to comply with air quality permit standards when operating on biogas. RAMIFICATIONS OF NOT TAKING ACTION Without carbon-cleaned digester gas,OC San will not be able to operate within SCAQMD Title V permit requirements at both Central Generation Plants. PRIOR COMMITTEE/BOARD ACTIONS N/A ADDITIONAL INFORMATION A Notice Inviting Bid was issued on September 19,2024,and two bids were received on October 28, 2024.

S-2024-636BD 1 Purpose This Scope of Work (SOW) describes the Contractor requirements for testing and calibration of protective devices (relays and circuit breakers) located at the Orange County Sanitation District’s Reclamation Plant No. 1, Fountain Valley, CA; Treatment Plant 2, Huntington Beach, CA; and Pump Stations located throughout Orange County. 2 Description of Facilities 2.1 Reclamation Plant No.1 Reclamation Plant No. 1 processes an average of 130 million gallons of sewage a day (130MGD) to full secondary standards and then feeds 100MGD of the treated water to the Groundwater Replenishment System (GWRS); adjacent to Plant No. 1 and operated by the Orange County Water District. 2.1.1 Plant No. 1 Electrical System Description Plant No. 1’s electrical distribution system (see Appendix A-4: Single-Line Diagrams) consists of a primary-selective 12.47kV backbone fed from a double-ended Southern California Edison (SCE) 66kV -12.47kV utility substation (SCE Orcosan Sub). The backbone supplies power to 12 Power Buildings some of which have diesel standby generators. A major component of the backbone system is the Central Generation (CenGen) facility that produces 12kV power via up to three (3), 2.5 megawatt reciprocating engines running continuously on sludge digester gas and natural gas. The CenGen facility operates in parallel with SCE utility power and directly feeds several of the Power Buildings. The 12.47kV system contains a mix of medium voltage vacuum circuit breakers with protective relays and load interrupter switches with fuse protection. Most Power Buildings are double-ended with 480V secondary-selective switchgear. The Blower Buildings are double-ended with 4.16kV and 480V switchgear. Plant No. 1 also has several support building complexes that have single-ended 480V and 208V main switchboards with fixed molded-case circuit breakers. All motor control centers (MCCs) that have internal main breakers have fixed mold-case main circuit breakers. Other MCCs are directly fed from upstream breakers and have no internal main. 2.2 Treatment Plant No. 2 EXHIBIT A Page 2 of 18 Specification No. S-2024-636BD Treatment Plant No. 2 processes an average of 80MGD of sewage to full secondary standards and pumps the treated water into the Pacific Ocean via a five-mile-long Ocean Outfall. Although Plant No. 2’s average daily flow is less than Plant No. 1’s 130MGD, the Plant No. 2 outfall pumping system has been constructed to manage up to 600MGD of wet-weather storm flow from both Plant No. 1 and Plant No. 2. 2.2.1 Plant No. 2 Electrical System Description The Plant No. 2 electrical distribution system (see Appendix A-4: Single-Line Diagrams) consists of a primary-selective 12.47kV backbone fed from Southern California Edison (SCE) 66kV -12.47kV utility substation (SCE Orcogen Substation). The backbone supplies power to seven (7) Distribution Centers (having 12kV switchgear) and Power Buildings, some with diesel standby generators. The Plant No. 2 CenGen facility produces 12kV power via up to five (5), three (3) megawatt reciprocating engines running continuously on sludge digester gas and natural gas and a one (1) megawatt steam turbine running on engine exhaust waste heat. The CenGen facility operates paralleled with SCE utility power and directly feeds several of the Distribution Centers and Power Buildings. As at Plant No. 1, the Plant No. 2 12.47kV system contains a mix of medium voltage vacuum circuit breakers with protective relays and load interrupter switches with fuse protection. Most Distribution Centers and Power Buildings are double-ended with 480V secondary-selective switchgear. Distribution Center H and the Gas Compressor Building are double-ended with 4.16kV and 480V switchgear. The Operations Center and Maintenance Building have single-ended 480V main switchboards, the Operations Center with switchgear breakers, the Maintenance Building with fixed molded-case circuit breakers. MCCs that have main breakers use fixed molded-case main circuit breakers at Plant No. 2. 2.3 Collections/Pump Stations OC San’s 388 miles of collection system pipelines and 15 pump stations are spread throughout Orange County and include 363 miles of gravity pipelines, 21 miles of force mains, four (4) miles of inverted siphons, and 4,469 manhole structures.

The goal of this process will be to produce a sequence of equipment lineups available for testing at each Plant or any Pump Station for Contractor’s four (4)-week look-ahead schedules.( As discussed in section 5.3.3 below.) The Contractor shall be aware that although the work will require interruptions of power to portions of treatment plant facilities, OC San’s overall daily wastewater treatment mission cannot be compromised. However, there are some locations such as Pump Stations with radial feed which do not have redundancy and require more careful planning. The Contractor shall also be aware that although the Testing Plan may initially result in consequence outages for testing work each week at each Plant or any Pump Station with no lapses, this objective will become less attainable as the testing work progresses. The following scheduling requirements shall apply in planning the testing work. EXHIBIT A Page 8 of 18 Specification No. S-2024-636BD 5.3.1.1 Simultaneous Testing at Both Treatment Plants The Contractor shall be ready to perform testing work at both Plants simultaneously using two (2) work crews. The third (3rd) crew shall perform testing at Pump Stations which may take place during off-hours. Each crew must be managed by its own Lead Technician. 5.3.1.2. Weekly Rate of Device Test Completion Test Events will be organized based on a sequence of equipment line ups (480V Motor Control Center, 480V or 12.47kV Switchgear (Bus A or Bus B)) outage availability. The plan shall be minimum of one (1) equipment line up with associated relays and circuit breakers completed per week at each Plant or any Pump Station. 5.3.1.3 Total Schedule Duration The total schedule duration shall be up to thirty-six (36) months from the Project Kickoff Meeting date. 5.3.1.4 Contractor Work Schedule While most work is expected to be performed between 7:30am and 3:00pm, Monday through Thursday, some outages may be required to be performed on weekends or in the early morning hours to coincide with low water flow periods. 5.3.1.5 OC San Electrical Maintenance Staff Work Schedule The Contractor may perform testing work while OC San staff has gone on breaks (but not during lunch period). However, if OC San staff assistance is required for a particular test planned during a morning or afternoon break, the Contractor shall perform other work at that location until OC San staff returns. 5.3.1.6 Substitute Work Location The Testing Plan shall be so arranged that, within Plant operational constrains, a substitute equipment lineup will be available should a scheduled equipment line up become unavailable. Should substitution be required, no extra cost will be incurred by OC San. 5.3.1.7 Minimizing Generator Time The Testing Plan shall be arranged that, within Plant operational constrains, portable generator time is minimized. EXHIBIT A Page 9 of 18 Specification No. S-2024-636BD 5.3.1.8 Interruption of Testing Work The Contractor shall be aware that situations will arise wherein a previously planned Test Event may be cancelled before work begins. Or, during the progress of work on a Test Event, OC San may require interruption or termination of the Test Event to restore power if alternate treatment process workarounds cannot be arranged. Should either of these circumstances arise, OC San reserves the right to direct the Contractor to another location in the Plant. The Contractor’s efforts to relocate in these circumstances shall count as an additional mobilization/demobilization if less than 24 hours’ notice is given. 5.3.1.9 Cancellation of Testing Work – by OC San If OC San must cancel a scheduled Test Event due to unforeseen circumstances and the Contractor has already mobilized for that Test Event, OC San will pay the cost of Test Event Mobilization/Demobilization per Exhibit B. If OC San must cancel a scheduled full day of testing within multiple-day Test Event, OC San will pay for a Cancelled Test Day per Exhibit B. 5.3.1.10 Cancellation of Testing Work – by Contractor If the Contractor must cancel a scheduled Test Event or day of testing within a Test Event, the Contractor shall notify OC San Contract Manager via e-mail as soon as possible, but no later than the 24 hours on the prior business day. The e-mail shall state the reason for cancellation. If the Contractor does not notify OC San before the day of testing, the Contractor shall provide a credit to OC San for the cost of Cancelled Test Day per Exhibit B. 5.3.1.11 CenGen Bus “G” Testing Testing of protective devices on the CenGen Bus G at Plant No. 1 only. Testing will require a complete shutdown of all CenGen generators, which is a significant risk of cost impact to OC San. The Contractor shall work with OC San staff to plan this critical Test Event to minimize outage time to Plant No. 1 CenGen Bus G. Note, Plant No. 2 CenGen Bus G protective devices will not be tested under this Contract. 5.3.2 Walkdown of all Plant Equipment Jobsites In conjunction with Planning Conferences below, the Contractor shall participate in a complete walkdown of all Plant equipment job sites at both Plants to verify site and equipment conditions, note details, and sufficiently prepare for all Test Events. Separate visits to Pump Stations will be arranged to verify site and equipment conditions (estimated quantity of total trips is three (3)) as Pump Stations are located remotely. EXHIBIT A Page 10 of 18 Specification No. S-2024-636BD 5.3.3 Look-Ahead Schedule In coordination with the Overall Testing Plan, the Contractor shall prepare and maintain a rolling 4-Week Look-Ahead Schedule to confirm adherence to the Testing Plan. 5.3.4 Weekly Testing Meeting The Contractor shall participate in regular weekly meetings with OC San staff to review testing progress, discuss upcoming test events and any difficulties being encountered in accomplishing the work. The Contractor shall submit the 4-week Look-Ahead Schedule at each meeting. 5.4 Test Events Activities This section describes the interaction of OC San Electric Maintenance Staff and Contractor’s crew during the stages for a Test Event. The Contractor’s test technicians shall prepare in advance before the first day of testing by researching the devices to be tested so that equipment downtime and delays of device testing caused by inadequate preparation are minimized. The actual duration of each Test Event should not exceed its pre-approved time limit whenever possible. OC San staff will notify Contractor of the scheduled date and duration of each upcoming Test Event in advance.

OPERATIONS COMMITTEE Agenda Report Headquarters 18480 Bandilier Circle Fountain Valley, CA 92708 (714) 593-7433 File #:2024-3961 Agenda Date:12/4/2024 Agenda Item No:7. FROM:Robert Thompson, General Manager Originator: Riaz Moinuddin, Director of Operations & Maintenance SUBJECT: CENTRIFUGE DEWATERING LUBRICATION RING PUMP REPLACEMENT AT PLANT NO.2, PROJECT NO. MP2-015 GENERAL MANAGER'S RECOMMENDATION RECOMMENDATION: A. Approve a Sole Source General Services Contract with DXP Enterprises, Inc. for the Centrifuge Dewatering Lubrication Ring Pump Replacement at Plant No. 2, Project No. MP2- 015, for a total amount not to exceed $211,158; and B. Approve a contingency of $21,116 (10%). BACKGROUND The Orange County Sanitation District (OC San)Centrifuge Dewatering facility at Plant No.2 dewaters digested sludge,converts the sludge to biosolids cake and conveys biosolids to the Truck Loading facility for removal using piston pumps capable of operating at 1500 psi discharge pressure. To reduce pumping pressure in the biosolids cake headers,a lubrication ring system was supplied by the piston pump manufacturer.The lubrication ring pumping system supplies lubricant to the biosolids cake headers at various points between the Centrifuge Building and the Truck Loading facility to reduce friction. The current lubrication ring pumps manufactured by OBL are of foreign origin,costly,and are difficult to procure replacement units or parts for from the manufacturer.OC San staff and the original system design engineer performed an assessment to evaluate alternative pumps that can perform the design function and are readily available.The assessment identified a Milton Roy pump that will perform the intended function with minimal tubing modifications and a similar pressure rating without the need for electrical power or controls upgrades. RELEVANT STANDARDS ·24/7/365 treatment plant reliability ·Comply with environmental permit requirements ·Maintain a proactive asset management program Orange County Sanitation District Printed on 11/26/2024Page 1 of 3 powered by Legistar™ File #:2024-3961 Agenda Date:12/4/2024 Agenda Item No:7. ·Operate and maintain facilities to minimize impacts on surrounding communities, including odor, noise, and lighting PROBLEM The current lubrication ring pumps manufactured by OBL are of foreign origin,costly,subject to long lead times,and difficult to procure replacement units or parts from the original equipment manufacturer (OEM). PROPOSED SOLUTION Replace the original lubrication pumps with the Milton Roy lube pumps provided by DXP Enterprises, Inc. identified by the engineering assessment. TIMING CONCERNS N/A RAMIFICATIONS OF NOT TAKING ACTION If the lubrication pump system fails on the same cake transfer pipe,the increase in backpressure could potentially result in costly damage or premature wear of the cake transfer pumps resulting in extended downtimes. PRIOR COMMITTEE/BOARD ACTIONS N/A ADDITIONAL INFORMATION Milton Roy is the OEM board approved sole source (9/29/21 Board Award M.O.17(B)).DXP Enterprises,Inc.is the sole authorized distributor of Milton Roy pumps,and the OEM Sole Source List will be updated next quarter to reflect this change.

FROM:Robert Thompson, General Manager Originator: Riaz Moinuddin, Director of Operations & Maintenance SUBJECT: SITE ACCESS AND LICENSE AGREEMENT - ROCCS BREA DOSING STATION GENERAL MANAGER'S RECOMMENDATION RECOMMENDATION: Recommend to the Board of Directors to: A. Approve a new site access and property license agreement with ROD International Holdings, LLC to lease property to install, maintain, and operate a chemical dosing station at 835 South Brea Boulevard in the City of Brea for a term of 36 months at the following lease terms, in a form approved by General Counsel: ·February 01, 2025, through January 31, 2026, $4,036.26 each month, ·February 01, 2026, through January 31, 2027, $4,133.35 each month, ·February 01, 2027, through January 31, 2028, $4,233.35 each month; and B. Authorize the General Manager or designee to negotiate and approve one optional 36-month lease renewal period, in a form approved by General Counsel. BACKGROUND The Orange County Sanitation District (OC San)uses chemicals for odor and corrosion control in its collection systems,which also help reduce odors at the treatment plants.The Regional Odor and Corrosion Control Services (ROCCS)program operates ten remote continuous chemical dosing sites in nine member agency cities to minimize odors and extend the pipes'life expectancy.The real property is leased when the OC San property is unavailable at the chemical dosing site.Since January 01,2019,this location has been leased to dose chemicals into the Euclid Trunk to reduce odors in the cities of Brea,Fullerton,Anaheim,Garden Grove,and Fountain Valley to reduce reliance on caustic shock dosing. Before acquiring this location,OC San mitigated hydrogen sulfide in Euclid trunkline with intermittent slug doses of caustic soda chemical to raise the pH in the pipeline.The higher pH has the temporary impact of killing the slim layer growing on the pipeline walls which produces hydrogen sulfide.After treatment,the slim layer will regrow,especially during the warmer months.Increasing the slug dosing frequency can harm the biological treatment systems in the plants.A continuous chemical dosing station was built on the private property at 835 S.Brea Boulevard to provide an effective odor control program for the Euclid Trunk Sewer.Real property is leased for continuous chemical dosingOrange County Sanitation District Printed on 11/26/2024Page 1 of 3 powered by Legistar™ File #:2024-3979 Agenda Date:12/4/2024 Agenda Item No:8. control program for the Euclid Trunk Sewer.Real property is leased for continuous chemical dosing stations when OC San doesn’t own property near the top of its gravity main sewer trunks. RELEVANT STANDARDS ·12 or fewer odor complaints per year under normal operating conditions in the collection system ·Operate and maintain facilities to minimize impacts on surrounding communities, including odor, noise, and lighting ·Protect OC San assets PROBLEM The 36-month lease agreement with ROD International Holdings,LLC expires on January 31,2025. Renewal options ended and exceeded the Board’s authorized approval. PROPOSED SOLUTION Staff recommends renewing the lease with ROD International Holding,LLC at for the first year with an approximate 3% increase each subsequent year until January 31, 2028. TIMING CONCERNS If no action is taken immediately, the City of Brea will experience a lapse in odor control service. RAMIFICATIONS OF NOT TAKING ACTION Without action,magnesium hydroxide addition to the Euclid trunk will cease.Normal biological action in the sewer system will produce odors in an uncontrolled manner.An alternative odor control treatment is an intermittent slug dosing using caustic soda,which is partially effective and increases the potential for elevated odors and resulting complaints and problems in the collection systems. PRIOR COMMITTEE/BOARD ACTIONS January 2019 -Approved a new Site Access and License agreement with Polfit Wellness,Inc.,to lease property for the purpose of installing,maintaining,and operating a chemical dosing station at 835 South Brea Boulevard,in the City of Brea,for a term of 36-months,at the following lease terms, in a form approved by General Counsel:February 1,2019 through January 31,2020,$2,600 per month;February 1,2020 through January 31,2021,$2,652 per month;February 1,2021 through January 31,2022,$2,705 per month;approved a new Sewer License and Maintenance Agreement with the City of Brea to allow the Orange County Sanitation District to access,install,and operate the Slip Line within the City Sewer;and authorized the General Manager or designee to negotiate beginning June 1,2021 and subsequently award an option for an additional 36-month lease renewal period.

FROM:Robert Thompson, General Manager Originator: Mike Dorman, Director of Engineering SUBJECT: OCEAN OUTFALL BOOSTER STATION ELEVATOR REHABILITATION, PROJECT NO. SC20-02 GENERAL MANAGER'S RECOMMENDATION RECOMMENDATION: Recommend to the Board of Directors to: A. Approve a Purchase Order to TK Elevator (TKE) for Ocean Outfall Booster Station Elevator Rehabilitation, Project No. SC20-02, using Sourcewell Cooperative Contract No. 020923-TER for an amount not to exceed $216,981; and B. Approve a contingency of $43,396 (20%). BACKGROUND The Orange County Sanitation District (OC San)operates the Ocean Outfall Booster Station (OOBS) at Plant No.2.Staff uses the freight elevator to deliver and remove equipment between the ground level, basement, and second floor. RELEVANT STANDARDS ·Ensure the public’s money is wisely spent ·Participate in local, state, and national cooperative purchasing programs ·Maintain a proactive asset management program PROBLEM The OOBS elevator,installed in 1989,has become increasingly unreliable and requires frequent repairs.Currently,it is out of service,as replacement parts are difficult to source due to the obsolescence of its equipment. PROPOSED SOLUTION Approve a Purchase Order for Ocean Outfall Booster Station Elevator Rehabilitation,Project No. SC20-02.This project will rehabilitate and modernize the elevator with new equipment using current technologies. This project requires modifications to existing equipment,some of which may only becomeOrange County Sanitation District Printed on 11/25/2024Page 1 of 2 powered by Legistar™ File #:2024-3412 Agenda Date:12/4/2024 Agenda Item No:9. This project requires modifications to existing equipment,some of which may only become accessible once work begins,increasing the risk of unforeseen costs.Given the relatively small value of this purchase order,staff recommends a 20%contingency to provide funds for addressing unexpected conditions or changes that can prevent a delay that could expose OC San to extended overhead costs by the contractor. TIMING CONCERNS The OOBS elevator is currently out of service and in need of repairs.Approving this Purchase Order to modernize the existing elevator and its related equipment is the most efficient solution to replace the outdated components and restore the elevator to full operation as quickly as possible. RAMIFICATIONS OF NOT TAKING ACTION The OOBS elevator will remain inoperable until repair parts are procured and addressed.OC San will continue to incur maintenance repair costs with long lead times and limited elevator availability. PRIOR COMMITTEE/BOARD ACTIONS N/A ADDITIONAL INFORMATION OC San utilizes a Cooperative Agreement through Sourcewell (formerly National Joint Powers Alliance),Cooperative Contract No.020923-TER,in accordance with Ordinance No.OC SAN-61, Section 2.03(B),Cooperative Purchases.This Cooperative contract was awarded using a competitive bid process like OC San’s and has been vetted by OC San’s Purchasing Division. CEQA The project is exempt from CEQA and a Notice of Exemption will be filed with the OC Clerk-Recorder and State Clearing House after the OC San's Board of Directors approval of the Purchase Order. FINANCIAL CONSIDERATIONS This request complies with the authority levels of OC San’s Purchasing Ordinance.This item has been budgeted (Budget FY 2024-25 and 2025-26,Section 8,Page 52,Operations &Maintenance Capital Program, Project No. M-SM-CAP) and the budget is sufficient for the recommended action.

FROM:Robert Thompson, General Manager Originator: Mike Dorman, Director of Engineering SUBJECT: LOS ALAMITOS SUB-TRUNK AND WESTSIDE RELIEF INTERCEPTOR REHABILITATION, CONTRACT NO. 3-64C GENERAL MANAGER'S RECOMMENDATION RECOMMENDATION: Recommend to the Board of Directors to: A. Receive and file Bid Tabulation and Recommendation for Los Alamitos Sub-Trunk and Westside Relief Interceptor Rehabilitation, Contract No. 3-64C as part of the Rehabilitation of Western Regional Sewers, Project No. 3-64; B. Approve a project budget increase of $2,300,000 for Rehabilitation of Western Regional Sewers, Project No. 3-64, for a new total project budget of $96,300,000; C. Award a Construction Contract Agreement to T. E. Roberts, Inc., for Los Alamitos Sub-Trunk and Westside Relief Interceptor Rehabilitation, Contract No. 3-64C, for a total amount not to exceed $35,320,572; and D. Approve a construction contract agreement contingency of $3,532,057 (10%). BACKGROUND This contract represents the final phase of the Rehabilitation of Western Regional Sewers,Project No.3-64.The Los Alamitos Sub-Trunk and Westside Relief Interceptor sewers were constructed in 1959 and are within the cities of La Palma,Cypress,and Los Alamitos along Oak Street,Sausalito Street,Chestnut Street,Cerritos Avenue,Bloomfield Street,Orange Avenue,Moody Street,and Denni Street and an easement through Forest Lawn Cemetery. RELEVANT STANDARDS ·Achieve less than 2.1 sewer spills per 100 miles ·Comply with California Public Contract Code Section 20103.8,award contract to lowest responsive, responsible bidder ·Ensure the public’s money is wisely spent Orange County Sanitation District Printed on 11/26/2024Page 1 of 4 powered by Legistar™ File #:2024-3900 Agenda Date:12/4/2024 Agenda Item No:10. PROBLEM The upper reaches of the Los Alamitos Sub-Trunk suffer from capacity issues,while other sections have deteriorating pipe joints,corroded manholes,structural weaknesses,calcium blockages, inflow/infiltration problems,and limited access for cleaning.The Westside Relief Interceptor also faces similar challenges,including deteriorated pipe joints,corroded manholes,structural damage, cracked pipes,calcium deposits,and inflow/infiltration issues that impede maintenance.The presence of undersized pipes and damaged joints reduces system capacity by allowing groundwater infiltration and stormwater inflow.Additionally,untreated manhole corrosion could lead to structural failures that impact the surrounding pavement.Calcium buildup at pipe joints caused by mineral-rich groundwater further complicates proper pipe cleaning. PROPOSED SOLUTION Award a Construction Contract Agreement for the Los Alamitos Sub-Trunk and Westside Relief Interceptor Rehabilitation,Contract No.3-64C.This contract will replace one mile of sewer pipe with 24-inch through 26-inch high-density polyethylene pipe and rehabilitate six miles of sewer lines with chemical grout injection to reduce the risk of flow blockages,sewage spills,and pipeline failures, while also addressing inflow and infiltration issues.This contract will also add or replace 28 manholes and rehabilitate 71 existing manholes. TIMING CONCERNS Delay in awarding the contract would result in further calcium buildup,increased pipe blockages,and ongoing corrosion, potentially impacting the reliability of the collections system. RAMIFICATIONS OF NOT TAKING ACTION Failing to upsize and rehabilitate the sewer pipelines will elevate the risk of spills,increase maintenance demands,and ultimately lead to the failure of these critical assets.A pipeline failure would not only cause a significant sewage spill but also pose serious risks to public health and safety, necessitating a complex and costly bypass system for repairs. PRIOR COMMITTEE/BOARD ACTIONS N/A ADDITIONAL INFORMATION Orange County Sanitation District (OC San)advertised Los Alamitos Sub-Trunk and Westside Relief Interceptor Rehabilitation,Contract No.3-64C,for bids on July 15,2024,and one sealed bid was received on August 27, 2024. A summary of the bid opening follows: Engineer’s Estimate $27,200,000 Bidder Amount of Bid T. E. Roberts, Inc.$35,320,572 A pre-bid survey was conducted on August 16,2024,and four bidders confirmed that they intended Orange County Sanitation District Printed on 11/26/2024Page 2 of 4 powered by Legistar™ File #:2024-3900 Agenda Date:12/4/2024 Agenda Item No:10. A pre-bid survey was conducted on August 16,2024,and four bidders confirmed that they intended to submit a bid, so adequate competition was expected. Prior to the bid opening,one bidder that previously confirmed their intention to submit a bid,indicated that they would not be bidding.They cited concerns about the qualification requirements,specifically those related to pipe bursting experience.This requirement mandated that the prime contractor either have direct experience in pipe bursting or show experience supervising a subcontractor performing this work.The potential bidder requested that this requirement be removed from the Invitation for Bid. To ensure the success of the project,staff carefully evaluated the project specific challenges associated with pipe bursting,and the sensitive nature of the work environment,which includes residential streets and sections through Forest Lawn Cemetery during restricted nighttime hours. Given these considerations,staff opted to maintain the existing experience requirements for pipe bursting without modifications. After the single bid was received,a post bid survey was conducted with the companies who previously responded to the bid survey.All companies cited they could not meet the pipe-bursting qualification requirements. The bid was evaluated in accordance with OC San’s policies and procedures.Since the single bid amount was 30%higher than the engineer’s estimate,staff conducted several meetings with T.E. Roberts,Inc.to perform a cost analysis of their bid.During the evaluation of the bid amount,it was determined the primary difference between the engineer’s estimate and the construction bid stemmed from the cost of bypass pumping.This was primarily due to longer pumping durations,the need for additional pump watch personnel because of the length of the pipe,and increased standby equipment required to address potential spills.OC San performed an updated cost estimate based on the contractor’s bypass pumping bid elements and the bid amount is 4%higher than the revised engineer’s estimate. Moving forward with the project as bid provides the best approach to meet the operational and reliability needs of OC San.Staff recommends awarding a Construction Contract Agreement to the lowest responsive and responsible bidder,T.E.Roberts,Inc.,for a total amount not to exceed $35,320,572.A notice was sent to the bidder on November 21,2024,informing them of the intent of OC San staff to recommend award of the Construction Contract Agreement to T.E. Roberts. Inc. CEQA This project is covered in the “Rehabilitation of Western Regional Sewers,Project No.3-64 Environmental Impact Report (EIR)State Clearinghouse Number 2015111077.This EIR was certified by the Board of Directors and a Notice of Determination was filed on March 23, 2017. FINANCIAL CONSIDERATIONS This request complies with the authority levels of OC San’s Purchasing Ordinance.This item has been budgeted (Budget FY 2024-25 and 2025-26,Section 8,Page 22,Rehabilitation of Western Regional Sewers,Project No.3-64).This item will increase the project budget and will be funded from the CIP budget.

PCSA CONTRACT NO. 3-64C Revised 081823 LOS ALAMITOS SUB-TRUNK AND WESTSIDE RELIEF INTERCEPTOR REHABILITATION Page 16 of 19 22. INDEMNIFICATION To the fullest extent permitted by law, CONSULTANT shall indemnify, defend (at CONSULTANT’s sole cost and expense and with legal counsel approved by OC SAN, which approval shall not be unreasonably withheld), protect and hold harmless OC SAN and all of OC SAN’s officers, directors, employees, consultants, and agents (collectively the “Indemnified Parties”), from and against any and all claims, damages, liabilities, causes of action, suits, arbitration awards, losses, judgments, fines, penalties, costs and expenses including without limitation, attorneys’ fees, disbursements and court costs, and all other professional, expert or consultants fees and costs and OC SAN’s general and administrative expenses (individually, a “Claim”, or collectively, “Claims”) which may arise from or are in any manner related, directly or indirectly, to any work performed, or any operations, activities, or services provided by CONSULTANT in carrying out its obligations under this Agreement to the extent of the negligent, recklessness and/or willful misconduct of CONSULTANT, its principals, officers, agents, employees, CONSULTANT’s suppliers, consultants, Subconsultants, subcontractors, and/or anyone employed directly or indirectly by any of them, regardless of any contributing negligence or strict liability of an Indemnified Party. Notwithstanding the foregoing, nothing herein shall be construed to require CONSULTANT to indemnify the Indemnified Parties from any Claim arising from: (A) the sole or active negligence or willful misconduct of the Indemnified Parties; or (B) a natural disaster or other act of God, such as an earthquake; or (C) the independent action of a third party who is neither one of the Indemnified Parties nor the CONSULTANT, nor its principal, officer, agent, employee, nor CONSULTANT’s supplier, consultant, Subconsultant, subcontractor, nor anyone employed directly or indirectly by any of them. 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 PCSA CONTRACT NO. 3-64C Revised 081823 LOS ALAMITOS SUB-TRUNK AND WESTSIDE RELIEF INTERCEPTOR REHABILITATION Page 17 of 19 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. CONSULTANT PERFORMANCE The CONSULTANT’s performance shall be evaluated by OC SAN. A copy of the evaluation shall be sent to the CONSULTANT for comment. The evaluation, together with the comments, shall be retained by OC SAN and may be considered in future CONSULTANT selection processes. 25. COMPLIANCE WITH OC SAN POLICIES AND PROCEDURES CONSULTANT shall comply with all OC SAN policies and procedures including Attachment “L” - Contractor Safety Standards, as applicable, all of which may be amended from time to time. 26. CLOSEOUT When OC SAN determines that all work authorized under the Agreement is fully complete and that OC SAN requires no further work from CONSULTANT, or the Agreement is otherwise terminated or expires in accordance with the terms of the Agreement, OC SAN shall give the CONSULTANT written notice that the Agreement will be closed out. CONSULTANT shall submit all outstanding billings, work submittals, deliverables, reports, or similarly related documents as required under the Agreement within thirty (30) days of receipt of notice of Agreement closeout.

OC SAN will provide a list of cost codes by phase to the CONSULTANT. The CONSULTANT shall also provide a summary of progress and expenditures to date. OC SAN will provide a sample invoice structure to the CONSULTANT after the issuance of the Notice to Proceed (NTP) for this SOW. 4.1.1 – PMWeb Procedures This project shall utilize PMWeb as the Project Control Management System (PCMS) for overall management of the work. All PCMS related documents requiring formal signatures shall be digital, and all copies digitally distributed. The PCMS conforms to the requirements set forth in California Government Code section 16.5 regarding digital signatures; therefore, digital signatures are in full force and effect and are legally the same as a hand-written signature. At least one PCMS account shall have the authority to approve Amendments. OC SAN shall maintain the PCMS and serve as the administrator for the duration of this project. OC SAN will provide the CONSULTANT with user access for approved personnel as needed for the duration of the project. OC SAN shall control access to the PCMS by assigning user profiles and login credentials. The SCOPE OF WORK PROJECT NO. 3-64C PCSA Page 5 of 10 CONSULTANT shall notify OC SAN of any changes to personnel. Access modifications shall be coordinated as needed. Do not share PCMS account passwords with anyone inside or outside of the company. Routine maintenance of the PCMS system may be required during the project. Access to the PCMS system may be restricted or unavailable at these times and will be scheduled outside of typical working hours whenever possible. The PCMS is a web-based environment and is therefore subject to the inherent speed and connectivity problems of the Internet. The CONSULTANT is responsible for its own connectivity to the Internet. PCMS response time is dependent on the CONSULTANT’s equipment, including processor speed, Internet access speed, Internet traffic, etc. OC SAN will not be liable for any delays associated with the utilization of the PCMS including, but not limited to slow response time, down time periods, connectivity problems, or loss of information. OC SAN will provide a one-time training session of up to two hours to train the CONSULTANT’s designated staff on general system requirements, procedures, and methods. Automated system notifications generated by PCMS (e.g., in-system notices, system generated email, or email with attachment) shall constitute a formal written notification in compliance with the Professional Construction Services Agreement (PCSA). 4.1.2 - PMWEB SCHEDULE OF SUBMITTALS OC SAN has standardized a Schedule of Submittals to provide uniformity between projects, support a commissioning dashboard, and ensure that submittals are properly retained per the Records Retention Policy. OC SAN has developed an Excel template based on OC SAN’s Master Specifications. OC SAN will provide a PMWeb Master Schedule of Submittals template that includes the submittals required by OC SAN’s Master Specifications. The CONSULTANT shall not deviate from the PMWeb Master Schedule of Submittals, except as required by the project specifications. The CONSULTANT shall develop submittal items for specifications that are not part of OC SAN’s Master Specifications. After the CONSULTANT has developed the Schedule of Submittals, it will be provided to the Resident Engineer and the Contractor to finalize before submittals are loaded into PMWeb. Submittals will be loaded into PMWeb based on the package (general construction, safety, and commissioning packages) and commissioning phase. Task 4.2 – Initial Project Meetings 4.2.1 - Construction Hand-Off Workshop The CONSULTANT shall participate in a two-hour construction hand-off workshop.

J-135B GENERAL MANAGER'S RECOMMENDATION RECOMMENDATION: Recommend to the Board of Directors to: Approve a contingency increase of $711,765 to the existing Sole Source Service Contract with Cooper Machinery Services LLC for Engine and Generator Overhauls at Plant Nos.1 and 2,Project No.J-135B,as part of Central Generation Engine Overhauls at Plant Nos.1 and 2,Project No.J- 135, for a new total contingency of $5,284,985 (18%). BACKGROUND In the early 1990s,Orange County Sanitation District (OC San)installed eight internal combustion engines manufactured by Cooper Bessemer at the Central Generation (CenGen)facilities at Plant Nos.1 and 2 to generate electricity using digester gas.During normal operating conditions,CenGen facilities supply approximately 60%of the electricity at Plant No.1 and 95%of the electricity at Plant No. 2. In July 2022,a Sole Source Service Contract was awarded to Cooper Machinery Services LLC for Engine and Generator Overhauls at Plant No.1 and 2,Project No.J-135B.The work under this contract overhauls four engines and refurbishes five generators. RELEVANT STANDARDS ·Maintain a proactive asset management program ·Comply with environmental permit requirements ·Use all practical and effective means for resource recovery PROBLEM The original contract called for the overhaul of four engines,with all parts disassembled and inspected,however,only specific parts were to be replaced based on their estimated remaining useful life.During the overhaul of the first two engines,additional components outside the original scope were found needing replacement or repair.While the original contract did include one new set of pistons and one camshaft re-lobe,these parts are needed for each engine.Change orders have already been issued to cover the complete overhaul of two of the four engines.While the remainingOrange County Sanitation District Printed on 11/26/2024Page 1 of 3 powered by Legistar™ File #:2024-3987 Agenda Date:12/4/2024 Agenda Item No:12. already been issued to cover the complete overhaul of two of the four engines.While the remaining contingency funds are sufficient to cover the third engine,it is expected to be insufficient to cover the cost of the fourth and final engine under this contract. PROPOSED SOLUTION Approve a contingency increase to the existing Sole Source Service Contract to cover additional costs associated with completing the overhaul of the fourth engine and potential future unforeseen change orders. TIMING CONCERNS The third engine overhaul began in September 2024,and the fourth is planned for July 2025. Delaying this action would delay the overhaul of the fourth engine. RAMIFICATIONS OF NOT TAKING ACTION If the contract contingency is not increased,the remaining contingency would be divided between the third and fourth engines to maximize the overhaul efforts.Priority would be given to fully overhauling the third engine,which may leave the fourth engine short of being fully functional.Incomplete overhauls could reduce system reliability and may result in potential SCAQMD permit violations. PRIOR COMMITTEE/BOARD ACTIONS April 2023 -Approved the addition of funds to include generator overhauls as part of the construction contract with Cooper Machinery Services LLC for the Engine and Generator Overhauls at Plant Nos.1 and 2,Contract No.J-135B,in the amount of $1,637,117 (5.6%),for a total construction contingency of $4,573,220 (15.6%). July 2022 -Awarded a Sole Source Service Contract to Cooper Machinery Services LLC for Engine and Generator Overhauls at Plant No.1 and 2,Project No.J-135B,for a total amount of not to exceed $29,361,029; and approved a contingency of $2,936,103 (10%). ADDITIONAL INFORMATION The contingency increase authorized in April 2023 was to rewind three generators,which was not included in the original contract.A portion of the original contingency was used to rewind the first two generators. CEQA The project is exempt from CEQA under the Class 1 categorical exemptions set forth in California Code of Regulations Section 15301. FINANCIAL CONSIDERATIONS This request complies with the authority levels of OC San’s Purchasing Ordinance.This item has been budgeted (Budget FY 2024-25 and 2025-26,Section 8,Page 43,Central Generation Engine Overhauls at Plant No.1 and 2,Project No.J-135)and the budget is sufficient for the recommendedOrange County Sanitation District Printed on 11/26/2024Page 2 of 3 powered by Legistar™ File #:2024-3987 Agenda Date:12/4/2024 Agenda Item No:12.

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. OC San manages asset reliability, mitigates risk, and ensures the quality of our delivered services according to the following stated intent or mission statement of the 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. 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 over 380 miles of regional trunk sewer pipelines and 15 pump stations throughout the OC San service area (Figure ES-1). Wastewater is conveyed to Reclamation Plant Number (No.) 1 in Fountain Valley and Reclamation Plant No. 2 in Huntington Beach. These facilities treat an average daily wastewater flow of more than 190 million gallons per day, serving over 2.6 million people in central and northern Orange County, California. 2024 Asset Management Plan ES-2 Please see the comprehensive Acronyms and Abbreviations list for definitions.

The FY 2024–2025 Budget Update, the first year of the 2-year budget adopted in June 2024, includes updates to the 20-year Capital Improvement Program (CIP) outlay. Figure ES-7 includes current and projected CIP projects. The green bars show the current proposed CIP projects while the yellow bars show the future CIP projects, which are reevaluated and adjusted annually to reflect any new information. Figure ES-7. 20-Year CIP Outlay This page left blank intentionally 2024 Asset Management Plan 1 1 Introduction The Orange County Sanitation District (OC San) Board of Directors (Board) developed mission and vision statements to clearly communicate OC San’s purpose to our stakeholders and to articulate OC San’s organizational objectives. OC San’s vision supports the mission by expressing what we strive to achieve now and into the future. 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’s asset management policy states: OC San will assess and manage the collection system and treatment plant systems and assets to improve resilience and reliability while lowering life cycle 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 The asset management policy calls for the following initiatives: • Create an annual Asset Management Plan (AMP) 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 ensure the OC San’s resources are focused on the high-priority work functions. • Maintain a 20-year forecast of all CIP projects needed to maintain or upgrade OC San’s nearly $14.0 billion in assets on a prioritized risk basis to establish rate structures. OUR VISION Orange County Sanitation District 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. Our Mission To protect public health and the environment by providing effective wastewater collection, treatment, and recycling. 2024 Asset Management Plan 2 The AMP is a living document that describes evolving operational strategies, maintenance, and refurbishment plans and adaptations, and Capital Improvement Program (CIP) implementation initially captured in the Facilities Master Plan and revised on an annual basis through the budgeting process. The information included in the AMP 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: • Take a proactive approach to repair, rehabilitate, and replace. • Ensure assets are reliable and operating when needed. • Minimize unplanned outages and equipment downtime. • Manage risks associated with asset or service impairment through asset performance optimization. • Develop cost-effective management strategies for the long term. • Strive to implement world-class asset management strategies through continual improvement in our asset management practices. The AMP is a key component of OC San’s overall planning activities. It aligns with OC San’s Strategic Plan and the Facilities Master Plan (inclusive of the 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 AMP with the other planning activities. Table 1-1. 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 AMP 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 AMP and refined as appropriate. 20-year Varies Asset Management Plan Documents the overall condition of treatment and collection system major 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 and greater Annual Budget Book 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 AMP identifies new operational, maintenance, and capital improvement activities for consideration during the budget development process. 2-year Annual 2024 Asset Management Plan 3 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 185 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 over 380 miles of regional trunk sewer pipelines and 15 pump stations throughout OC San’s service area (Figure 1-1). Wastewater is conveyed via the collection system to Reclamation Plant Number (No.) 1 in Fountain Valley, and Reclamation Plant No. 2 in Huntington Beach, where resource recovery and wastewater treatment take place. OC San’s reclamation plants 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 treated water is released 5 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 (GWRS), 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. 2024 Asset Management Plan 4 Figure 1-1. OC San’s Service Area 2024 Asset Management Plan 5 1.1.1 Collection System OC San’s collection system serves as a regional conveyance system, collecting and conveying wastewater flows from 20 cities, 4 special districts, and various unincorporated areas, and accommodates dry weather urban runoff. OC San’s more than 380 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 more than 4,450 manhole structures. OC San has worked with member city and agency staff to understand future development plans and flow estimates and has collected historical inflow and infiltration rates during wet weather events to ensure adequate flow-carrying capability exists in each trunk sewer system. OC San also factors in the effects of drought and lower domestic water usage rates to make sure the sewers operate properly at low-flow rates. Table 1-2 summarizes the design capacities of the pump stations, which reflect the maximum capacity of each station when all duty pumps are on and standby pumps are off. Table 1-2.

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 (M&D) structure, mechanical bar screens, grit chambers, and primary basins, before going to one of two air-activated sludge (AS) processes, or trickling filters (TFs), and secondary clarifiers. Thereafter, secondary effluent is diverted to OCWD’s facilities for tertiary treatment before reuse. For a summary of Plant No. 1 design capacity, refer to Table 1-3. For a map of the facilities and more detailed understanding of how Plant No. 1 treatment processes work together, 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, and is interconnected to the Plant No. 2 facility. In addition, Plant No. 1 includes facilities for odor control and chemical addition to support the aforementioned processes. Reclamation 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-AS secondary treatment facility or the TFs/solids contact basins. With the construction of the GWRS final expansion and associated projects completed in 2023, Plant No. 2 is able to operate in a separated stream mode, splitting non-reclaimable and reclaimable streams. Additionally, both Plant No. 2 reclaimable secondary effluent and Plant No. 1 secondary effluent are diverting most of their treated water to OCWD for advanced treatment and groundwater injection. For a summary of Plant No. 2 design capacity, refer to Table 1-4. For a map of the facilities and more detailed understanding of how Plant No. 2 treatment processes work together, before and after the final expansion of the GWRS, refer to Appendices C, D, and E, respectively. 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 the Central Power Generation System as a renewable fuel for energy generation. Compressed digester gas can be shared between the plants through the interplant digester gas line. Table 1-3.

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. Based on the findings of a comprehensive assessment study completed in 2022, a rehabilitation project is in progress to ensure the outfall’s reliability for many years to come. Outfall No. 1 serves as an emergency outfall and primary backup to Outfall No. 2, discharging treated wastewater over a mile offshore at a depth of approximately 65 feet. It was originally constructed in 1954 and was later modified in 1965. OC San’s NPDES permit specifies that this outfall can be used only 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 2024 Asset Management Plan 8 emergency use only and serve as a secondary backup to the primary outfall facilities, ensuring the safety and welfare of the community at large. 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 pump stations). The estimated replacement value for Fiscal Year (FY) 2024–2025 is $14.0 billion based on the Engineering News-Record Construction Cost Index (CCI) increases since the 2017 Facilities Master Plan. Figure 1-2 shows the valuation information, presented in five general subprocess areas: • Collections Systems Piping • Collection Systems Pump Stations • Reclamation Plant No. 1 Facilities • Reclamation Plant No. 2 Facilities • Interplant, Joint, and Common Facilities Figure 1-2. FY 2024–2025 Facility Valuation by Area 1.3 Asset Management Organization Asset management is an essential part of OC San and our overall mission to deliver safe, economical, and reliable wastewater treatment services. Every part of our organization is Collection System - Piping, $4.16, 30% Collection System -Pump Stations, $0.43, 3% Reclamation Plant No. 1 Facilities, $3.69, 27% Reclamation Plant No. 2 Facilities, $4.81, 34% Interplant, Joint, and Common Facilities, $0.89, 6% Facility Valuation (in $billions, 2024 dollars) Total Valuation: $14.0 2024 Asset Management Plan 9 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 collaborative effort, each OC San group plays an important role in ensuring that the individual asset management initiatives and projects are properly executed (Figure 1-3). Figure 1-3. Groups with 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, 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. • Planning provides engineering support for short- and long-term management of assets, while working toward asset management objectives. The Asset Management Group works in the Planning Division of Engineering interfacing with Operations, Maintenance, and the other Engineering Divisions on a regular basis. • Project Management Office manages the design and construction of new facilities and the rehabilitation of older facilities. The Small Projects Delivery Team within the Project Asset management activities are performed throughout OC SAN Operations Maintenance Planning Project Management Office Design Construction Management 2024 Asset Management Plan 10 Management Office is responsible for the design of facilities’ maintenance, repair, and replacement projects. • 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 documents. To fulfill our commitment to our ratepayers to provide safe and reliable services, OC San’s Asset Management Program is structured to align the Engineering Department and Operations and Maintenance (O&M) Departments. OC San’s Asset Management Group, within Engineering’s Planning Division, consists of nine Asset Engineers assigned to the various process areas in the treatment plants and collection system. They are responsible for understanding the key issues or concerns related to the condition and performance 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 affect the operation, condition, process, and/or maintenance-related issues within their assigned areas. The Operations Team focuses on operating assets to extend equipment life and minimize energy and chemical use, while meeting all regulatory and level of service requirements. The Maintenance Team is committed to maintaining installed assets in a ready state for Operations in a cost-effective manner that optimizes planned maintenance activities. Collectively, the Area Asset Engineer and O&M work together to reach the goal of providing the required level of service to our customers at the lowest life cycle 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 processing deficiencies in a timely manner. 1.3.1 Major Assets A “major asset” is defined as any asset that is specifically tracked, monitored, or recorded for the purposes of fulfilling the policies and initiatives of the AM Program. While a major asset is typically defined as a higher-level assembly of simple assets, a major asset can be composed of other assets. For example, while collectively a clarifier can be called a major asset, it is composed of other assets such as pumps, drive mechanisms, motors, etc. Similarly, for buried assets, a system of pipe segments known as a trunkline can be called a major asset. The Asset Engineer uses the term major asset to differentiate and communicate for purposes related to the execution of the AMP, which includes developing short-, medium-, and long-term plans for each process area. “Major assets” are sometimes simply referred to as “assets” for simplicity purposes. Here are some examples of tests that are used to differentiate between a major asset and merely an asset: • Does it perform a substantial role in the collection, treatment, or effluent process? • Does its direct use help us to meet level of service and quality metrics? • Does it require a predictive, proactive, or preventive maintenance (PM) service approach to facilitate its management? • Does its failure present a large impact on a process or system? • Is its reliability pertinent to the operation of the plant? • Does its function, or lack thereof, present a detriment to plant performance metrics? • Is it critical to the operation of the plant? • Does it have a propensity to affect or influence the safety of the plant? • Does it directly influence plant permit compliance? There are other variations of the definition of an “asset” outside of the AMP. These variations are typically minor and unique to the identifying group based on specific goals and objectives. For example, some variations in the definition exist between those defined in the AMP and by 2024 Asset Management Plan 11 the Maintenance and Finance Departments. The Maintenance definition of an asset serves the Maintenance Department goals and objectives by providing a means to properly track and maintain those items using the Enterprise Asset Management (EAM) system, Maximo®. Furthermore, the AMP definition of an “asset” deviates from the Finance and Accounting Division’s definition as it is based on accounting practices for tax purposes. In summary, the Asset Management, Maintenance, and Finance groups look at and define assets somewhat differently and it is important to identify those similarities and differences to maintain alignment among the groups to achieve OC San’s common goals and objectives. 1.3.2 Remaining Useful Life An asset’s Remaining Useful Life (RUL) is the estimated time remaining until the asset cannot be reliably maintained and fails to provide the required level of service. Failure includes structural failure as well as operational/service failure. The Asset Management Program converts RUL into RUL scoring for each asset on a scale of 1 to 5 per Table 1-5. Table 1-5. Remaining Useful Life Score versus Remaining Useful Life RUL Score 5 4 3 2 1 RUL < 5 years 5–10 years 11–15 years 16–20 years > 20 years Asset Engineers determine the RUL of major assets based on a variety of factors: • Expected RUL from original installation, repair, or rehabilitation date(s) and regular maintenance activities based on historical data (when available) • Condition assessments, including manned or remote inspections as applicable • O&M field observations and recommendations • Performance, maintenance, and reliability history, including condition monitoring reports from the Maintenance Reliability Group • Regular field inspections of asset areas • Engineering judgment 1.3.3 Predictive Maintenance In asset management, Predictive Maintenance (PdM) strategies are used to regularly monitor the condition of assets. OC San’s Maintenance Reliability Group implements the PdM Program, which collects data through condition monitoring to provide real-time performance evaluation of assets. PdM is a proactive approach that minimizes unexpected breakdowns, extends the mean time between failures (MTBF), and reduces not only the likelihood of failure but also overall equipment downtime and repair costs by monitoring the actual equipment health through quantifiable means and performing advanced analysis and failure detection to identify condition degradation in its early phase (Figure 1-4). In addition, when sudden changes or variations in the process manifest, they are often found during the regular Maintenance Reliability rounds as part of the group’s everyday work. The ability to monitor equipment lends itself to helping Maintenance optimize intervals between corrective repairs, minimizing the number and cost of unscheduled repairs created by machine-train failures, improving the overall equipment reliability, and assisting the Asset Management Group with accurately determining an asset’s RUL. 2024 Asset Management Plan 12 Figure 1-4. PdM Summary 1.3.3.1 Mechanical Discipline The mechanical discipline involves variance trending of the PdM test results, which includes the following: • Vibration analysis to measure imbalance in rotating equipment • Oil analysis to predict lubricant and equipment degradation • Airborne ultrasound • Structure ultrasound • Infrared thermograph to detect hot spots • Iris™ motion camera (measures deflection and displacement) – Motion amplification camera In addition to PdM activities for mechanical equipment, OC San also uses laser alignment techniques to enhance rotating machinery accuracy to increase the machinery’s operating life span. 1.3.3.2 Electrical Discipline The electrical PdM Program includes the following tests: • Oil analysis for transformers • Ultrasound to detect arcing • Infrared thermography to detect hot spots • Circuit breakers and protective relays testing • Motor circuit analysis for large and small motors to determine motor stator health, broken rotor bars, deteriorating motor connections, and any impending failure trends • Medium-voltage feeder cable testing to determine the health of cables and insulation 2024 Asset Management Plan 13 1.3.3.3 Civil Discipline The civil aspect of PdM includes the following: • Closed-circuit television (CCTV) assessments of buried pipe and manhole structures • Sonar assessments of inverted siphons • Structural sampling, testing, and analysis of concrete assets • Water-level monitoring and debris accumulation prediction in the collection system 1.3.4 Preventive and Corrective Maintenance Beyond the advanced PdM strategies, OC San also performs time and cycle-based 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 the following two groups of skilled individuals to reinforce and sustain the following activities: • OC San has created a PM Optimization Group that is tasked with conducting in-depth assessments to optimize PM strategies for new and existing assets and to establish maintenance approaches and strategies for assets installed by projects prior to beneficial occupancy. The PM Optimization Program tracks, maintains, and manages assets throughout their life cycles, from design, construction, commissioning, beneficial occupancy, operation, and maintenance to the eventual decommissioning or replacement of those assets. This ensures that the asset life cycle is maximized with the lowest risk of 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 PM 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 PM and CM programs are 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. 1.3.4.1 Civil Discipline PM and CM activities include: • Cleaning of civil facilities and pipelines (collection system) • Chemical conditioning of the sewage to reduce corrosion and control odors • Minor repairs • Application and repair of coatings • Maintenance and testing of cathodic protection systems 1.3.4.2 Mechanical, Electrical, and Instrumentation Disciplines PM and CM activities include: • Valve and gate exercising program comprising more than 264 PM tasks for over 1,650 valves and gates throughout both plants and collection system • Equipment rotation program to ensure equipment wear is predictable 2024 Asset Management Plan 14 • Mechanical equipment adjusting and alignment • Equipment rebuilding and regular testing • Changing of lubricants and filters • Electrical equipment cleaning and torque verification • Electrical power distribution equipment testing • Circuit breaker and protective relay testing • Sensors and meters calibration 1.3.5 Asset Lifecycle Curve D-I-P-F The ‘P-F’ curve is a concept that identifies the intervals between Potential Failure ‘P’ and Functional Failure ‘F’ and was first introduced by Stan Nowland and Howard Heap in 1978. The curve has since been extended to include Design ‘D’ and Installation ‘I’ by Doug Plucknette and is called the ‘D-I-P-F’ curve, also known as the Asset Lifecycle Curve. At OC San, it is understood that detecting potential failure alone is simply not enough to consider a program a success. For each detected potential failure, it is also important to determine the root cause of the failure and know how to eliminate the cause. OC San’s goal is to ensure all asset stakeholders are working together to move to the left of the ‘P-F’ curve into the ‘I-P’ precision domain with proper installation, commissioning, precision alignment, and balancing through good work processes, procedures, and practices. Ultimately, the goal is to apply the lessons learned into the future designs to improve asset reliability and resistance to failure and minimize maintenance costs. 1.4 Reference Society for Maintenance and Reliability Professionals (SMRP). 2013. Maintenance and Reliability Best Practices. 4th Edition. 2024 Asset Management Plan 15 2 State of OC San’s Infrastructure The Area AM Summaries provide a list of major assets and are intended to summarize information on those assets, including condition, average RULs, key issues under further investigation, and plans to address performance and reliability issues of these assets over the 1-, 5-, and 10-year planning horizons, as well as CIP projects planned over the next 10 to 15 years. Over the course of the year, Asset Engineers present one or more of the Area AM Summaries to the OC San Managers who make up the AM Council. All the process areas, pump stations, and collection systems are presented with feedback and questions being provided by the AM Council. The Area AM Summaries are updated as needed and incorporated into the AMP, which is published annually. 2.1 Area Asset Management Summaries The Area AM Summaries provide a high-level overview of the assets in the areas contained in Section 2.2. The 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 summaries include the following: • Plant No. 1 • Plant No. 2 • Collection System – Pump Stations • Collection System – Pipelines and Manholes The Area Asset Management Summaries include an area map (Figure 2-1 through Figure 2-4) showing the general layout of the process areas or collection system, and a table (Table 2-1 through Table 2-4) with the following fields: • Area No.: Number that corresponds to individual plant asset areas.

Some assets have very little remaining life or have failed already and will need interim solutions before they are addressed by the project, these assets include exhaust fans, the hydrogen sulfide (H2S) monitoring system, and corroded piping and grit paddles. Continue to actively monitor the condition of aging assets scheduled for repair under P1-105 and develop appropriate solutions as applicable. Permanent solutions will be provided by Project P1-105. Metering & Diversion (M&D) – The trunkline pipes inside the M&D building are at the end of their useful life and are experiencing accelerated corrosion causing recent failures and leaks (Sunflower and Santa Ana River Interceptor [SARI]). O&M is also experiencing issues with the flow meters being inaccurate. Planning is coordinating with O&M to perform condition assessments on each trunkline and repair as needed to extend the useful life of the piping within the next year. Instrumentation is also replacing the troubled flow meters during these assessments. M&D structure and piping along with the flow meters will be rehabilitated/replaced by Project P1-105. Sunflower Pump Station – This pump station is equipped with two screw pumps, which are experiencing issues with bearings and gear boxes. These assets in the pump station are approaching the end of their useful lives. The pump station structure also has coating failure and concrete deterioration along with rebar corrosion. While Pump No. 1 was being rehabilitated by FE19-04, Pump No. 2 failed, resulting in Sunflower Pump Station being completely out of service. Pump No. 2 trough had deep grooves that have been repaired with grout and has since been put back in service by Maintenance. A maintenance project installed metal I-beams inside the outlet channels as temporary supports to strengthen the structure supporting the gearbox concrete pads before wet season starts. FE19-04 is replacing Pump No. 1 with associated gear box, bearings, and couplings and rehabilitating the concrete trough. The project is also upgrading electrical equipment and instrumentation required for successful operation of Pump No. 1. A separate project will be planned for the 2025 dry season to rehabilitate both outlet channels to repair the concrete, rebar, and coating. Finally, Pump No. 2 will eventually be replaced by a separate project, which will be similar in scope as FE19-04 after P1-105 construction is complete in 2028. Wastehauler Station – The automated sampling systems installed by FE20-01 have been experiencing some issues with the valves, switches, and touch screens causing shutdowns and delays. The connection point height and angle create an upward flow direction, which is not ideal, causing waste to drain out when haulers disconnect, leading to additional odor. The team has been working with the vendor to troubleshoot equipment issues and making warranty claims. A planning study is recommended to review the ongoing issues at the wastehauler station and propose solutions to be implemented by future CIP Project X-102, Wastehauler Facility Improvements, to improve the operation and maintenance of the facility. Steve Anderson Lift Station HVAC – Both HVAC and condensing units have passed their useful lives with excessive corrosion and reliability issues. Critical electrical equipment and controls at the station are in danger of failure due to heat and humidity levels if these units are not replaced in a timely manner. N/A FE23-06 will replace the existing HVAC and condensing units with new units of the same/similar design to ensure that the systems will continue to maintain adequate temperature and humidity for critical electrical equipment in the building that serves the Ellis Avenue Trunk.

These issues require ongoing attention from Maintenance and can affect Plant No. 1’s treatment capacity. The scum pumps serving these basins are also obsolete, which means parts cannot be procured quickly for repairs when some of the pump are down, causing significant interruption to operation The center feed channel was recently inspected during a month-long planned outage; settled grit at the bottom of the channel was cleaned out and repairs were made to the T-lock liner to extend the useful life of the structure. Condition assessments and repairs of the primary basin tanks will be planned in conjunction with O&M activities in the coming years to increase reliability of the basins prior to the future rehabilitation project. P1-133 has recently replaced five of the six launders in the Primary Influent Splitter Box (PISB), installed new variable frequency drives (VFDs) for the three dilute sludge pumps serving basins 6–15, and replaced the three dilute sludge pumps serving basins 17–31. This will increase the reliability of the rectangular primary basins for the coming decade before X-017 provides a general rehabilitation of the primary sedimentation basins. Rectangular Primary Basins 6–31 Scum Pumps – The scum pumps are approaching the end of their useful lives. The pumps are also obsolete. Replacement parts are difficult to find and have a long lead time. O&M needs to perform regular PM on scum pits and pumps to prevent scum accumulation in the basins, especially during times when capacity is reduced by construction. FE23-05 will replace the obsolete scum pumps to improve scum pumping reliability and availability. Circular Primary Basins 3–5 Leakages – Operations indicated that water was still collecting inside the basins even after grouting and coating work was completed at Junction Structure A (JSA) and Primary Basin 3 and 4 influent pipes. Further leak testing conducted at the East Basin Distribution Box (EBDB) found that all stop gates and weir walls have leaks. A condition assessment of the 72-inch pipe was also conducted to determine whether any leakage may have come from cracks inside the pipe; however, the assessment found the pipe to be in good condition. The gates to basins 1, 2, and 5 were sealed shut to minimize leakage. P1-126 will eventually replace these circular basins. Scum Management – The scum collection systems 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. PRN-00563 will perform a comprehensive evaluation of the scum collection system and provide recommendations. The study will take the results of previous research studies, such as RE19-01, Primary Scum Equipment Evaluation at Plant No. 1 into consideration. X-017 will take into consideration the results of the Scum Study to improve the scum removal system during the rehabilitation. Waste Sidestream Pump Station (WSSPS) Pump Ragging and Grit – The pump station has been experiencing increased ragging issues due to the headworks shutdown scheduled for the P1-105 construction. Grit buildup has also increased resulting in Maintenance having to schedule grit removal monthly. The pumps are also approaching the end of their useful lives. Maintenance has increased the frequency of pump de-ragging and grit removal from the wet well as a mitigation. It is also recommended to install a de-ragger on one of the pumps to test out compatibility in this service. MP1-003 will replace one of the WSSPS pumps with a chopper type pump to test the performance of the new pump type for this service to mitigate the ragging issues and improve the station’s reliability. Upon improved performance, the other two pumps will be replaced with similar chopper pumps through a subsequent project. X-006 is the future project that will rehabilitate the pump station and increase the station’s capacity.

Aluminum dome supports for A-Side Primary Basin E and G are corroded. Currently, F and G are not available due to loss of structural integrity from severe corrosion of the rotating mechanisms. Availability of A-Side basins are critical to process non-reclaimable flow until P2-98A commissions four new primary basins. FE23-09 (formerly MP2-007) will rehabilitate failed and corroded rotating mechanisms at Primary Clarifiers F and G. P2-98A is in the construction phase to replace all four A-side primary basins. Reliability of B and C Side Primary Sedimentation Basins – B-side and C-side primary basins were built in the 1970s and 1980s, respectively. These basins are close to the end of their useful lives and require major rehabilitation to continue to operate reliably for next 30+ years. In April 2024, Maintenance staff observed noise from the drive at Primary Clarifier N. Following the Original Equipment Manufacturer’s (OEM’s) assessment, PRN-00997 is currently in progress to comply with the OEM’s recommendation to replace the drive. Each clarifier, including rotating mechanisms, will be inspected one at a time over the next several months to verify RUL and timing of the P2-133 project. P2-133 will provide long-term rehabilitation on B and C sides of primary basins. Functionality of Distribution Box B Gates – Distribution Box B has 10 leaking slide gates due to the absence of side seals in the original design. Repairs and installation of seals will be performed on one gate to test to start. Remaining gates will be repaired following a successful installation/test under Planning task order. P2-133 will provide long-term rehabilitation on B and C sides of primary basins and related systems such as Distribution Box B. Condition of Primary Effluent Junction Boxes – Junction boxes 2, A, B, C, D, and F were constructed in the 1970s and Junction E was built in 1983. Several of these structures have leaks at the pressurized manhole covers and will need repair or rehabilitation. Primary Effluent Junction Box 2 was inspected and a heavily corroded roof structure was identified. P2-98A will address the corroded roof for Primary Effluent Junction Box 2, but other effluent junction boxes (JB-A to JB-F), which have pressure manhole covers, are in the process of being assessed. N/A until short term action to perform condition assessment is completed. Reliability of Polymer System – The polymer system was built in 1988 and the RUL is limited.

Continue the aerator motor rebuild as needed. P2-136 will replace all oxygen piping, perform structural rehabilitation of the aeration basins, replace all aerators, and replace all inlet gates and oxygen analyzer panels. Secondary Clarifiers Issues – Broken clarifier mechanisms; unsafe access into clarifier basins; scum accumulation and recirculation process issue (scum is currently flowing to WSSPS-A and then is pumped back to PEPS to keep in the non-reclaimable stream); some handrails do not meet Occupational Safety and Health Administration (OSHA) requirements; Clarifier D&G chain and flight collapsed after MP-248 replacement. N/A FR2-0018 is under construction to replace the remaining six clarifiers left by MP-248, which replaced the worst six ones. FR2-0023 is under construction to add a safe entry access platform to each secondary clarifier. FR2-0031 will reroute the scum to DAFTs. P2-136 will replace part of the handrails. PRN-00989 will rebuild Clarifier D&G and add an alignment monitoring system. RAS/WAS Pump Station Reliability and Sizing – Obsolete VFDs; aged pumps; seismic risks; WAS pumps are oversized to cover low-flow condition. Continue to complete the pump overhaul being led by Maintenance. FE19-08 is replacing the RAS and WAS VFDs. X-107 will add structural improvements to mitigate seismic risks at East and West RAS/WAS PSs. X-052 will replace all RAS and WAS pumps and will consider WAS pumps to cover low-flow condition. Liquid Oxygen (LOX) Supply and Storage Issues – LOX Tank A had been demolished and not available until new tank is installed. LOX Tank B is over 40 years old and at the end of its useful life. Continue the maintenance activities to maintain the temporary LOX trailer and LOX Tank B. FE21-07 is in under construction for Tank A replacement. FE22-02 will replace LOX Tank B. PS22-02 evaluated the feasibility of onsite oxygen generation and recommended the installation of three 10-tons-per-day Vacuum Swing Adsorption (VSA) units. WSSPS - A Vulnerability – Flooding of the pump dry well has occurred in the past causing WSSPS pump motor damage. Maintain the sump pump to avoid fooding; rebuild the main pumps as needed. X-007 will replace the pumps with dry pit submersible type. DAFT Seismic and Safety Issues – DAFT structure is vulnerable to a seismic event and has lack of fall protection tie off points for maintenance activities.

Some are failing and have been replaced. OC San will monitor conditions for actuators and will note which ones are difficult to operate during regular PM activities. Since it would be a substantial effort to replace all actuators, a path for replacement/repair will be determined on a case-by-case basis depending on criticality. N/A OOBS and EPSA Operation and Maintainability Strategy – After J-117B completion, Low Flow Pump Station will be the main mode of operation, and OOBS and EPSA will stay on standby and be used during PWWFs. Continue current maintenance strategy for EPSA and OOBS. A future planning study will be created to identify operational and maintenance strategies for OOBS and EPSA. Condition of 120-inch Long Outfall – Planning Study PS18-09 Ocean Outfall Condition Assessment and Scoping Study performed a detailed inspection of the interior and exterior of the outfall, the ballast, and all associated components from the Beach Box to the end flap gate. The study identified 10 required project elements, four of which were immediate needs that were added as tasks to the project and resolved. However, six project elements remain that need to be addressed (see Long-Term Actions and Recommendations for details). N/A Project J-137 will address the remaining project elements identified from PS18-09: • Remove debris blocking diffuser access • Replace inspection opening hold-down hardware • Add additional ballast rock in areas identified by 3-D bathymetry survey • Replace existing manhole covers and appurtenances • Remove outfall sediment deposits • Replace flap gate Condition of 78-inch Short Outfall – The short outfall was last used in 2012 and its condition is largely unknown. NPDES recently added requirements for external inspection of the short outfall every 2.5 years. External remotely operated vehicle inspection and reporting on the marine portion of the short outfall was completed in July 2023 and concluded that there were no significant observations requiring immediate attention or action. J-137 will provide rehabilitation of the 120-inch Ocean Outfall as well as inspection and recommended repairs on the 78-inch Outfall. Deterioration of Emergency Overflow Wingwalls – The two emergency overflow weirs allow emergency overflow discharges to the Santa Ana River via concrete wingwall structures. Investigations performed under PS17-10 concluded that both structures are gradually deteriorating and if not addressed soon, could require substantial rehabilitation within 6-7 years. N/A P2-139 will provide rehabilitation of concrete and rebar at the wingwalls and foundation slabs. Reliability of Sodium Bisulfite System (SBS) –. The SBS has only been utilized a few times since 2015. Prior to this, higher discharges of effluent to the ocean outfall required dechlorination of disinfected effluent. The infrequent usage of the system led to sodium bisulfite crystallization in tanks, piping, and other appurtenances. Additionally, the equipment at the station is in poor condition and overdesigned for its current usage. Installation of a tank-level transmitter along with associated wiring and conduit are in progress. A recirculation loop was installed from the existing pumps to the temporary tank to prevent crystallization of sodium bisulfite within the tank. This system will provide temporary use if needed during construction activities of P2-135 and J-137. P2-135 will replace the sodium bisulfite chemical feed and storage system.

Keep Holder K out of service. Minimize shutdown time of Holder I and J. FR2-0032 will repair Digester K dome by overlaying polymer concrete based on the condition assessment and structural analysis report. Digester C, D, F, G High-Rate Mixing Pump Reliability – Ragging issues. Digesters C, D, F, and G are the only four digesters that need to be upgraded with chopper pumps for the high-rate mixing pumps. All the high-rate mixing pumps on the other P2 digesters have been replaced with chopper pumps. Heat exchangers had already been purchased and stocked on site, ready for FE20-02. FE20-02 will replace high-rate mixing pumps, heat exchangers, sludge recirculation pumps, bottom sludge transfer pumps, and hot water pumps and piping. Digester Gas Balance Line Material Compatibility – Digester C, D, F, G, and I gas balance lines were constructed of polyvinyl chloride (PVC) pipes. Digester P, Q, R, and S gas balance lines were constructed of steel pipes. These gas lines are not meeting the current digester gas line standard of stainless steel and are prone to failure or corrosion. Coat the steel gas balance lines. FE19-10 will replace the PVC gas balance lines with stainless steel lines (FE19-10 was combined with FE20-02 as one bid). PRN-00990 was approved to add the steel gas balance line replacement to P2-137. Digesters P and R Structural Issue – Post-tensioned ring has deteriorated, impacting the structural integrity of the concrete domes. Digesters P and R are out of service. P2-137A will repair Digesters P and R post-tensioned rings and demolish Q-R bridge. Walking Bridge Structural Deficiencies – Six out of 13 bridges were red taped to prevent access after unsafe conditions were found from assessments due to major cracking, buckling, and potential rebar corrosion. Coat the steel bridges. Repair projects will inspect the bridges on a regular basis before the repair. FE19-10 will repair Digesters F-G and D-I bridges. FR2-0033 will repair Digester O-T bridge. P2-137 will repair 13 bridges and replace the Digester Q-R bridge to be demolished by P2-137A. Viewport Corrosion – There are three viewports on each digester. Most viewports are corroded, leaking gas from the seal, and need to be replaced. Maintenance is scheduled to replace the seals. PRN-00990 was approved to add the viewports replacement work to P2-137. One viewport per digester will be replaced, and the remining two will be abandoned and filled with proper filling material. Dig. E and H Flame Arrestors Access – No safe access to do maintenance work on the flame arrestors on the gas balance lines. Maintenance continues to setup manlift to access. PRN-00990 approved for P2-137 to add access platforms to those four flame arrestors. Heat Exchangers, Sludge Recirculation Pump, and Sludge Transfer Pump Reliability – Digester heat exchangers, recirculation pumps, and bottom sludge transfer pumps are nearing the end of their useful lives and need to be replaced. Maintenance to store spare heat exchangers, sludge recirculation pumps, and bottom sludge transfer pumps. PRN-00684 Maintenance Projects to replace heat exchangers, sludge recirculation pumps, and bottom sludge transfer pumps. (Digester E, H, L, M, N heat exchangers replacement completed, and E and H pump replacement completed.) FE20-02 will replace those units on Digesters C, D, F, and G. Digester I and J Coating Failure – Interior coating on walls and ceiling installed by P2-89 are peeling off gradually. Wash off the peeled coating after digester cleaning to avoid clogging the mixing pump and piping. Creating project to recoat Digesters I, J, and K interior. Digester Holder K needs to be coated. Overall Digester Reliability – Digesters are approaching the end of their useful lives and pose a risk of failure during a seismic event. Building new digesters is recommended by Biosolids Master Plan to address the seismic risk and provide the long-term Class B digestion reliability with the ability to convert to Class A digestion in the future. Perform PM, condition assessment, and incidental repairs. P2-137 will rehabilitate digesters including domes and walls repair, replace electrical and motor control centers (MCCs), relocate carbon canisters to ground level, and address other project elements mentioned above. P2-128 will build six new digesters. X-135 will replace Digesters P, Q, R, and S. XP2-131 will build three digesters/holders to replace Digesters I, J, and K.

Planning Study PS18-06 is establishing OC San design standards to address this issue moving forward and locations where deficiencies exist. Implement the recommended design standards from PS18-06 in future capital projects and consider addressing some locations sooner where a capital project isn’t planned in the near future. Flood Risk – OC San’s new pump stations are designed to specifically consider and mitigate flood risks; however, some older pump stations don’t meet the current standards. Specially, Edinger Pump Station is entirely below grade and located immediately adjacent to a flood control channel. OC San follows protocols ahead of major storm events to be sure facilities are prepared and in good working condition. Facilities are monitored closely during storm events so that staff can respond to any unexpected event quickly. Project 11-33 has started the design to replace and relocate the Edinger Pump Station to a different location with less flood risk and where critical infrastructure will be located above grade. Additionally, all new pump stations will consider flood elevations and locate critical electrical equipment accordingly. Accelerated Corrosion – Corrosion is a common problem in sewage systems due to the presence of H2S. This is exacerbated in locations where sewage becomes turbulent, which can include pump station wet wells. Additionally, in an effort to minimize odors throughout the community, some manholes in the collections system have been sealed to prevent gases from escaping, which accumulates more corrosive gases within the system. Project 5-68 has added odor scrubbers to six key pump stations where the wet wells have experienced pressurization issues. These new scrubbers will allow the wet wells to vent, reducing the amount of sewer gas trapped in the system while also scrubbing the air so it will not be an odor issue for the surrounding community. OC San routinely performs inspections on critical assets, including pump station wet wells. Recently, the MacArthur Pump Station wet well was assessed and was found to be in relatively good condition considering the age of the asset but will require some rehabilitation that will be completed under future project 7-63. In the coming year, the Crystal Cove and Lido Pump Station wet wells are expected to be inspected with an ongoing inspection plan following that. Groundwater Intrusion – Groundwater has penetrated 15th Street, A Street, Bitter Point, and Rocky Point Pump Stations. Groundwater may gradually compromise the strength of reinforcement within the concrete structure walls over time. Planning study XPS0065 will be launched to identify possible mitigation measures and long-term solutions to be incorporated into future pump station CIP projects. Implement long-term solutions identified by planning study XPS0065. Maintenance Access – In some cases, access to collections facilities is not ideal due to limited land or easement rights, other competing public uses, or outdated facilities, which don’t meet modern safety standards. One example is the MacArthur Pump Station force main, which is difficult to access because redundancy was not incorporated when the pump station was designed. Another example is the Slater Pump Station wet wells, which are isolated by slide gates within 48-inch manholes that are difficult to access. Capital project 7-68, currently in construction, will add another force main to serve MacArthur Pump Station. Project FRC-0017 will modify the wet well access at Slater Pump Station to provide a safer working environment for staff. OC San continues to improve planned maintenance processes and inter-agency coordination that allow crews to minimize impacts on the community during necessary maintenance operations. Testing of modern automatic air/vacuum valves could facilitate automatic venting of the Newport Beach force main system and minimize impacts on traffic on Pacific Coast Highway. There is also continued effort to research emerging inspection technologies, which could make difficult inspections more easily achievable or cost effective. Valve Operability and Reliability – Valves at the pump stations sometimes reach the end of their useful life sooner than in other applications due to the harsh raw sewage application. These valves are critical to the operation of the collections system. Projects FRC-0017 and FRC-0018 have been launched to replace valves at five pump stations Continue to monitor valve condition and RUL and launch small projects as necessary to replace valves that cannot wait for a larger rehabilitation/replacement project. Force Main Operability and Reliability – Force mains are some of OC San’s highest-risk assets but also some of the most challenging to assess. While these assets have been replaced and rehabilitated in a timely manner, there are many that have not received a detailed inspection since installation. A force main inspection plan has been developed to assess all the force mains within the next 5 years with support from the existing Condition Assessment program resources. The next planned assessments will occur at College and Slater Pump Stations. Continue to implement the force main inspection plan and continually reassess the timing and priority of inspections within the program. Future projects will also incorporate updated standards, which will look to add redundancy and improved access where feasible. Outdated Bubbler Level System – At multiple pump stations (Bay Bridge, Crystal Cove, Edinger, MacArthur, Main Street, Slater, Seal Beach), the bubbler systems are outdated and do not meet OC San’s latest bubbler system standard. They do not have redundancy or automatic blowdown and are becoming increasingly unreliable. Project FE23-03 has launched and is in the design phase to upgrade the level control systems at these pump stations to meet current OC San standards. Adhere to OC San level control system design standards in all future pump station improvement projects. 2024 Asset Management Plan 85 ASSET MANAGEMENT SUMMARY – COLLECTION SYSTEM – PUMP STATIONS Current and Future Projects Project No. Location Project Title Impacted Facilities 20 2 4 20 2 5 20 2 6 20 2 7 20 2 8 20 2 9 20 3 0 20 3 1 20 3 2 20 3 3 20 3 4 20 3 5 20 3 6 20 3 7 20 3 8 5-68 Newport Beach Newport Beach Pump Station Odor Control Improvements 15th Street, A Street, Bitter Point, Crystal Cove, Lido, and Rocky Point Pump Stations FE19-01 Multiple Portable Generator Connectors at Pump Stations 15th Street, A Street, Bay Bridge, Bitter Point, College, Crystal Cove, Edinger, MacArthur, Main Street, Rocky Point, Seal Beach, Slater, and Westside Pump Stations FE23-03 Multiple Pump Station Bubbler Level Control System Upgrade Seal Beach, Bay Bridge, Crystal Cove, Main Street, MacArthur, Slater, Edinger Pump Stations FRC-0018 Newport Beach Valve Replacements at Lido, Crystal Cove, A Street, and 15th St. Pump Stations 15th Street, A Street, Lido, and Crystal Cove Pump Stations XPS0065 Newport Beach Pump Station Groundwater Intrusion Study 15th Street, A Street, Bitter Point, and Rocky Point Pump Stations X-022 Newport Beach 15th Street Pump Station and Force Main Project 15th Street Pump Station X-041 Newport Beach A Street Pump Station and Force Main Project A Street Pump Station 5-67 Newport Beach Bay Bridge Pump Station Replacement Bay Bridge Pump Station SC22-02 Newport Beach HVAC Replacement for Plant No. 2 Centrifuge Building, Operations Building, and Bitter Point Pump Station Bitter Point Pump Station X-025 Newport Beach Bitter Point Pump Station Rehabilitation Project Bitter Point Pump Station FRC-0020 Costa Mesa College Pump Station Wet Well Rehabilitation College Pump Station X-040 Costa Mesa College Pump Station Replacement and Force Main Rehabilitation College Pump Station MPC-002 Newport Beach Crystal Cove Pump Station Automatic Transfer Switch Replacement Crystal Cove Pump Station 5-66 Newport Beach Crystal Cove Pump Station Upgrade and Rehabilitation Project Crystal Cove Pump Station 11-33 Huntington Beach Edinger Pump Station Rehabilitation Project Edinger Pump Station X-023 Newport Beach Lido Pump Station Rehabilitation Project Lido Pump Station 7-63 Newport Beach MacArthur Pump Station Rehabilitation Project MacArthur Pump Station 7-68 Newport Beach MacArthur Force Main Improvements MacArthur Pump Station 7-65 Irvine Gisler-Redhill Interceptor Rehabilitation Main Street Pump Station 7-64 Irvine Main Street Pump Station Rehabilitation Project Main Street Pump Station X-024 Newport Beach Rocky Point Pump Station Rehabilitation Project Rocky Point Pump Station FRC-0017 Huntington Beach Valve Replacements and Wet Well Access Improvements at Slater Pump Station Slater Pump Station 11-34 Huntington Beach Slater Pump Station Rehabilitation Project Slater Pump Station 3-67 Seal Beach Seal Beach Pump Station Replacement Seal Beach Pump Station PRN-00930 Seal Beach Navy Fence Replacement In-Kind Consideration Project for 3-67 Seal Beach Pump Station 3-68 Seal Beach Los Alamitos Sub-Trunk Extension and Westside Pump Station Abandonment Westside Pump Station MPC-003 Fullerton Decommission Yorba Linda Pump Station Yorba Linda Pump Station 2-73 Fullerton and Yorba Linda Yorba Linda Pumping Station and Spur Odor Station Demolition Yorba Linda Pump Station Yorba Linda Spur Odor Station Please see the comprehensive Acronyms and Abbreviations list for definitions.

This poses the potential risk of debris build up, which can negatively impact normal sewer operation and downstream facilities if suddenly released. OC San has completed sonar inspections for over 5 miles of large-diameter inverted siphons and gravity sewers. Sediment reports and hydraulic modeling data were utilized to confirm or amend the theoretical cleansing state of each pipeline segment. OC San is starting a new procurement to validate the accuracy of sonar inspections, validate the effectiveness of various cleaning methods, and analyze debris data for any trends. The work includes multiple rounds of cleaning and sonar inspections for select inverted siphons and gravity sewers as well as condition assessment and incidental repairs for the inverted siphons. The sonar validation project is expected to be completed in 2025. OC San is implementing an ongoing large-diameter cleaning program, and the list of recommended large-diameter inverted siphons and gravity sewers to regularly clean will be finalized after the sonar validation project is completed. Additionally, some large-diameter inverted siphons and gravity sewers may be significantly larger than required for current and future capacity needs and are not self-cleansing. After the sonar validation project is completed, OC San staff will evaluate which assets are good candidates for sliplining and will recommend adding them to upcoming CIP projects or the creation of new projects. OC San staff will further validate recommended sliplining projects as part of the work for the 2028 Collections Capacity Study. Condition Assessment of Gravity Pipelines – The current calendar-based CCTV program inspects pipelines every 5 years. For assets with 10 years or less RUL, inspections every 5 years may not be frequent enough to properly track asset deterioration rates. It is recommended that the frequency of monitoring of pipelines with RUL scores of 4 or 5 be increased from every 5 years to a higher frequency (that is, every 2.5 years). OC San staff recommend exploring the optimization of condition assessment resources for gravity pipeline assets such that condition assessment frequencies are closely tied to RUL and likelihood of failure and balanced given available resources. Condition Assessment of Inverted Siphons – Inverted siphons are regularly cleaned but are not inspected because they are typically inaccessible using CCTV equipment. Without this inspection data, it is difficult to accurately know the current condition and RUL of these assets. There are two efforts underway to kick off the condition assessment program for inverted siphons. One active procurement will perform condition assessment and incidental repairs to two high-priority inverted siphons in Orange on the SARI Trunkline, and the sonar validation project includes condition assessment and incidental repairs of select inverted siphons. Both efforts are expected to be completed in 2025. OC San staff continue to research emerging inspection technologies to identify potential cost savings or improved assessment data through new equipment and methods. Results of the pilot project and sonar validation project could affect this approach if alternative cleaning and inspection methods are more cost competitive. It is anticipated this effort will span over multiple years. Given the potential complexity (that is, bypassing and/or temporary plugging, traffic control, etc.) for inverted siphon inspections, variety in inspection methods that may be required, and different asset priorities based on asset RUL, the condition assessment program is being phased into separate projects with similar work and priorities. Groundwater Infiltration – CCTV identified areas experiencing significant groundwater infiltration in the Baker-Main, Bushard, Euclid, Knott, Miller-Holder, Newport, SARI, Sunflower, and Talbert trunkline systems. Specifically, significant groundwater infiltration is most prominent in the I-405 corridor in Costa Mesa, throughout the western regional trunklines of the Knott trunkline in Cypress, Los Alamitos, etc.; Jamboree Road and the Balboa Peninsula in Newport Beach; and various locations in Anaheim, Buena Park, Fountain Valley, Huntington Beach, Irvine, Garden Grove, Orange, Santa Ana, and Westminster. Areas with significant groundwater infiltration that are co-located with fractures or tuberculation are not suitable for chemical grouting and therefore have been identified as high-priority point repairs; refer to individual trunkline key issue tables for more details. Additional areas with groundwater infiltration do not have any other defects and are lower priority. Projects 1-23, 2-78, 3-60, 3-64A, B, and C, 5-69, 7-65, 11-35, X-085, X-129, X-130, X-134, and X2-79 will address the majority of areas with significant groundwater infiltration. Manhole Access – OC San staff have 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 have identified specific locations where manholes are difficult to access for maintenance, such as an easement area on California Department of Transportation property near I-5 and State Route 91, an easement area encroached upon by residents near the Wintersburg Channel in Huntington Beach, Crystal Cove, the southern portion of the Santa Ana River, Orange Park Acres, and North Tustin. OC San staff will track and prioritize access issues to address key concerns. High-priority access improvements will continue to be recommended as small projects or additions to an existing CIP project. Lower-priority access improvements will be recommended within the scope of future CIP projects where feasible. Uninspected Gravity Pipelines – 31 gravity sewers have never been inspected in the collection system between the Baker-Main, Coast, Knott, Newhope, Newport, SARI, and Sunflower trunkline systems. There is no condition data for these reaches to determine field-adjusted RUL. Refer to the key issue tables for the Baker-Main, Coast, Knott, Newhope, Newport, SARI, and Sunflower trunkline systems for more details. 10 of these gravity sewers are proposed to be abandoned as part of Projects 2-73 and 7-68.

During PWWFs, capacity issues were identified in a portion of the North Trunkline and Tustin Avenue sewers. N/A Project 7-69 will upsize a portion of the North Trunkline and Project X-084 will upsize a portion of the Tustin Avenue sewer to address existing capacity issues. Missing Air Jumpers – One out of 10 inverted siphon/reduction locations in the Baker-Main Trunkline system do not have air jumpers. N/A Project X-129 includes constructing a new air jumper. Pipeline Defects – CCTV identified several areas with significant fracturing of VCP pipelines. The largest concentration of fractures is in the Fairview Trunkline. There are also areas of significant root intrusion in and around existing fractures. Some blockages in OC San sewer mains may have contributed to a local sanitary sewer overflow in Orange in 2021. Future root treatment work is planned to stop root growth and prevent further damage to the pipelines prior to construction of Project 7-69. Isolated defects elsewhere not included or near a CIP project have been identified as high-priority defects. OC San staff are in the process of determining whether some pipelines can be abandoned or otherwise grouped together for 7-pack task orders to rehabilitate and/or repair the pipelines. Project 6-20 will rehabilitate the entire Fairview Trunkline to address pipeline fractures. Projects 7-65, 7-69, and X-129 will also address fracturing with rehabilitation work. Uninspected Gravity Pipelines – Two gravity sewers have never been inspected in the Baker-Main Trunkline system. There is no condition data for these reaches to determine field-adjusted RUL. These gravity sewers have a common manhole with a chemical line that must be temporarily relocated for CCTV access.

Manhole Defects – CCTV identified areas with significant liner delamination and some structures with exposed rebar, primarily in Buena Park, Cypress, and Los Alamitos. Five manholes included in Projects X-061, X-085, and X2-79 may reach the end of their useful lives prior to construction starting. Therefore, these manholes need some rehabilitation work performed via the manhole repair and rehabilitation blanket contract to prevent failure prior to the start of Projects X-061, X-085, and X2-79. Projects 3-60, 3-64A and C, X-061, X-085, X-130, and X2-79 will address the majority of the liner delamination and exposed rebar by rehabilitating the manhole structures. Other manholes are suitable for repair under the manhole repair and rehabilitation blanket contract. Pipeline Defects – CCTV identified several areas with significant fracturing of VCP pipelines. Most fractures are concentrated in northern Huntington Beach, Cypress, and with small-diameter sewers owned and operated by the City of Anaheim but maintained by OC San in the northern central area of the trunkline. There are also areas of significant root intrusion in and around existing fractures. A blockage due to roots occurred in one of pipe segments in northern Huntington Beach in 2022. Lastly, one pipeline with fractures also has a very large, encrusted deposit from groundwater infiltration. Root treatment work is planned for 2024 to stop root growth and prevent further damage to the pipelines prior to the construction of Project 11-35. OC San staff plan to use the industrial cleaning blanket contract to remove the large deposit to prevent a flow obstruction prior to construction of Project X-130. Isolated defects elsewhere not included or near a CIP project have been identified as high-priority spot repairs. OC San staff are in the process of grouping point repairs together for 7-pack task orders.

In addition, CCTV showed corrosion issues in upstream manholes due to an ineffective air jumper. N/A Project FE20-08 will replace a portion of the Olive Sub-Trunk siphon, rehabilitate other portions, reconstruct the air jumper, and restore the siphon into service. Increase Dry Weather Reclaimable Flows to P1 – To support the full production capacity of GWRS in future years, it is expected that more dry weather reclaimable flows are needed at OC San’s treatment plants. N/A Project 2-73 includes the construction of a new diversion to allow the routing of some flows from the SAR0345 branch into the Newhope Trunkline system. Manhole Defects – CCTV identified several areas with significant liner delamination and some structures with exposed rebar located in Anaheim, Fullerton, Garden Grove, Orange, Placentia, and Santa Ana. There are also three isolated manholes in the southern reaches of the Newhope Trunkline system with severe liner detachment, surface aggregate missing, and visible reinforcement. Two manholes in Project 2-73 may reach the end of their useful lives prior to construction starting. Therefore, these manholes need some rehabilitation work performed via the manhole repair and rehabilitation blanket contract to prevent failure prior to the start of Project 2-73. Projects FE20-08, FE21-08, 2-73, and 2-78 will address the majority of the liner delamination and exposed rebar by rehabilitating the manhole structures. Other manholes are suitable for repair under the manhole repair and rehabilitation blanket contract. Pipeline Fracturing – CCTV identified several areas with significant fracturing of VCP pipelines. Most fractures are concentrated in Fullerton. N/A Project 2-73 will address all of the fractures by rehabilitating or abandoning the pipelines. Pipeline Tuberculation – CCTV identified a few ductile iron pipelines in Craig Regional Park with no lining or significant delamination and widespread tuberculation. The last CCTV inspections for these assets were completed in 2013. CCTV frequency to be increased for all ductile iron pipelines and new CCTV inspections are needed for suspected unlined ductile iron pipelines. External condition assessment is also recommended to field verify the RUL of ductile iron pipelines. Ductile iron pipelines with 5 years or less of RUL with widespread liner delamination and tuberculation will be grouped into either 7-pack task orders or a new small project to rehabilitate the pipelines sooner than Project 2-73. Project 2-73 will address one of the pipelines with pockets of liner delamination and tuberculation. Uninspected Gravity Pipelines – 13 gravity sewers have never been inspected in the Newhope Trunkline system. There is no condition data for these reaches to determine field-adjusted RUL. This includes several cast-iron pipelines in a temporarily out-of-service pipeline in Craig Regional Park that are largely inaccessible. Four gravity sewers were recently constructed in 2017 and 2018 and have no access issues. All these reaches will be inspected via future CCTV PM work orders or separate CCTV work orders. Nine gravity sewers, including the temporarily out-of-service cast iron pipelines in Craig Regional Park, are proposed to be abandoned as part of Project 2-73.

During existing PWWFs, capacity issues were identified in the Taft Branch. During future PWWFs, capacity issues were identified in a northern portion of the SARI system. N/A Project 2-49 will address existing wet weather capacity issues in the Taft Branch and Project X-086 will address future wet weather capacity issues in a northern portion of the SARI system. Manhole Defects – CCTV identified widespread areas with significant liner delamination and some structures with exposed rebar. The defects are primarily concentrated in Anaheim, Orange, and Placentia. Some manholes in Projects 2-78 and X-134 may reach the end of their useful lives prior to construction starting. Therefore, these manholes need some rehabilitation work performed via the manhole repair and rehabilitation blanket contract to prevent failure prior to the start of Projects 2-78 and X-134. Projects 2-49, 2-73, 2-78, and X-134 will address the majority of the liner delamination and exposed rebar by rehabilitating the manhole structures. Other manholes are suitable for repair under the manhole repair and rehabilitation and manhole frame and cover repair blanket contracts. Missing Air Jumpers – Four out of 12 inverted siphon/reduction locations in the SARI Trunkline system do not have air jumpers. One location is a dual-barrel inverted siphon underneath the Santa Ana River channel with no nearby bridges that could be used for typical air jumper construction. Existing maintenance needs and issues with deep air jumper systems with condensate pumps are significant. There are also no residences nearby the upstream and downstream manholes. Therefore, OC San staff recommend performing additional monitoring and testing if there is sufficient H2S and air pressure to warrant constructing an air jumper of any type. Projects 2-78 and X-134 include constructing a new air jumper at three locations. Pipeline Defects – CCTV identified several areas with significant fracturing of VCP pipelines. Most fractures are concentrated in Anaheim and Orange. N/A Projects 2-73, 2-78, and X-134 will address fracturing issues by rehabilitating the pipelines. Unlined Ductile Iron Pipe – There are four pipeline assets that according to record information are unlined ductile iron pipe and have significantly surpassed their theoretical RUL based on installation date. The gravity sewers have limited inspection data, and the inverted siphon barrels have never been inspected. Perform new CCTV inspections and external assessments on all the ductile iron pipelines to field verify RUL. Gravity sewers are to be inspected with the pipeline CCTV blanket contract and there is an active procurement to CCTV inspect the inverted siphon barrels. Ductile iron pipelines with less than 10 years of RUL will be grouped into either 7-pack task orders or a new small project. Uninspected Gravity Pipelines – One gravity sewer in the SARI Trunkline system has never been inspected. There is no condition data for these reaches to determine field-adjusted RUL. This gravity sewer has a tight horizontal curve that may not allow for CCTV inspection and is blocked by a diversion board; OC San staff to discuss with pipeline CCTV contractor.

During existing PWWFs, capacity issues were identified in the entire Greenville Trunkline. N/A Project 1-24 will replace and upsize the entire Greenville Trunkline to address existing wet weather capacity issues, including sags, fractures, and widespread infiltration. Missing Air Jumpers – Four out of five inverted siphon locations in the Talbert Trunkline system do not have air jumpers. N/A Projects 1-23, 1-24, and X-129 include constructing new air jumpers at three locations. Project 1-24 also includes eliminating one inverted siphon, which subsequently eliminates the need for an air jumper at that location. Pipeline Fracturing – CCTV identified one VCP pipeline segment with significant fracturing. N/A Project X-129 will rehabilitate the fractured pipeline segment. Reinforced Concrete Pipe Corrosion Damage – Most of the reinforced concrete pipe pipeline of the Talbert Trunkline between I-405 and Bristol Street has moderate to severe surface aggregate loss in areas not rehabilitated by past project 1-17.

The metrics have been chosen to directly relate to the Asset Management Program objectives. The key objectives of the OC San Asset Management Program are as follows: • Take a proactive approach to repair, rehabilitation, and replacement. • Ensure assets are reliable and operating when needed. • Minimize unplanned outages and equipment downtime. • Manage risks associated with asset or service impairment through asset performance optimization. • Develop cost-effective management strategies for the long term. • Strive to implement world-class asset management strategies through continual improvement in our asset management practices. The following metrics and maintenance key performance indicators (KPIs) were chosen to demonstrate the effectiveness of the Asset Management Program and establish a baseline by which to gauge future performance: • The proactive maintenance percent, the percent of PM as a total of all maintenance, demonstrates the effectiveness of the maintenance program (proactive versus reactive). The percent PM includes predictive and PM of the assets. • 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. In Maximo®, the EAM system, this is described as a Level 50 priority. This is also described as break-in work that is deemed “emergency” or “extremely urgent” by staff. • 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 E. As the maintenance program moves toward a more proactive state, these costs and labor hours should decline over time. • Collections level of service results for sanitary sewer overflow (SSO) per 100 miles of sewer, odor complaints in the Collections system, and the CCTV program demonstrate the effectiveness of the combined efforts of Collections Maintenance, the Regional Odor and Corrosion Control System (ROCCS) program, and the Gravity Collections Condition Assessment Program as they pertain to asset management. The metric data were sourced from Maximo® from fiscal year databases—FY 2019–2020 through FY 2023–2024 and are included in Appendix E for reference. 3.2 Program Metrics 3.2.1 Proactive Maintenance Percent The proactive maintenance percent is the proportion of PM tasks compared to the total amount of maintenance performed. An increase in proactive maintenance percent represents a shift from a reactive to a proactive maintenance program. Table 3-1 and Table 3-2 provide the annual average of the proactive maintenance percent for both Reclamation Plant No. 1 and Reclamation Plant No. 2 for the past 5 years to illustrate recent trends and changes. For data from earlier years, refer to previous annual AMPs. For PM goals, OC San typically aims for a higher proportion of maintenance activities to be preventive rather than corrective, often 2024 Asset Management Plan 122 targeting around 70-80% preventive to 20-30% corrective, as these ratios tend to optimize efficiency and cost-effectiveness. OC San emphasizes a strong focus on PM to minimize unplanned corrective actions. Many of the process areas at both plants were at or below 60%, indicating that improvement in this area is likely over time as proactive maintenance programs are optimized and older facilities are replaced. Table 3-1. Proactive Maintenance Percent for Reclamation Plant No. 1 Process Area FY19/20 FY20/21 FY21/22 FY22/23 FY23/24 Preliminary 39% 39% 25% 41% 20% Primary 39% 32% 40% 37% 46% Interplant 84% 82% 59% 34% 17% Activated Sludge 53% 64% 56% 58% 50% Trickling Filters 56% 53% 47% 46% 46% Digesters 46% 46% 47% 42% 37% Solids Handling Facilities 34% 42% 44% 60% 46% Central Power Generation 64% 62% 62% 53% 57% Electrical Distribution 68% 65% 77% 77% 80% Utilities 33% 30% 26% 32% 20% Table 3-2.

The proactive maintenance percent for preliminary treatment at Plant No. 1 is in the lower range because Project P1-105, Headworks Rehabilitation, is in construction. Continued low-voltage cable failure at the headworks is causing the lower percentages of proactive maintenance work at Plant No. 2. Because of active construction work by Project J-117B, the effluent disposal area shows lower percentages in FY 2023–2024. Generally speaking, the pump stations have proactive maintenance percentages over 60% as shown in Table 3-3. Decreases in percentages are indicative of emergency work that was required and will be reflected in the break-in percentage illustrated later in this chapter. 15th Street Pump Station had a 20% decline in PM work last year. The main issues at 15th Street Pump Station, Lido, and ‘A’ Street Pump Station were frequent maintenance of check valves and related components, as well as recurring electrical problems and power outages. Crystal Cove had several issues with check valve, pumps, and instrumentation alarms resulting in the significant reduction in PM work. 2024 Asset Management Plan 123 15th Street Pump Station also experienced ongoing concerns with odor complaints and wet well maintenance. A recent valve replacement project at Bay Bridge Pump Station led to a significant improvement in the proactive maintenance percentage for FY 2023–2024 compared to previous years. Table 3-3. Proactive Maintenance Percent for Pump Stations Pump Station FY19/20 FY20/21 FY21/22 FY22/23 FY23/24 'A' Street 86% 85% 67% 60% 72% 15th Street 88% 85% 85% 84% 62% Lido 80% 42% 72% 50% 38% Bay Bridge 65% 34% 45% 37% 56% Rocky Point 96% 84% 76% 69% 51% Bitter Point 82% 76% 84% 74% 69% Seal Beach 55% 65% 50% 61% 38% Westside 75% 74% 80% 64% 73% Edinger 81% 79% 74% 44% 69% Slater 86% 86% 73% 78% 59% College 91% 69% 86% 72% 64% Crystal Cove 57% 91% 80% 90% 55% Yorba Linda 30% 92% 99% 80% 82% Main Street 66% 66% 76% 74% 69% MacArthur 66% 88% 83% 61% 71% Table 3-4 demonstrates average percent proactive work orders for the process areas at each plant (not including the interplant, effluent disposal, electrical, and utilities) and the pump stations. The data shows a slight decreasing trend in the annual average proactive work for both plants and pump stations. While there is not a consistently increasing or decreasing trend in Plant No. 1 and No. 2 data, pump stations show a decrease in the annual average proactive work. Table 3-4. Annual Average Proactive Work for Process Areas Proactive Work FY19/20 FY20/21 FY21/22 FY22/23 FY23/24 Plant No. 1 48% 47% 53% 45% 43% Plant No. 2 47% 49% 52% 45% 44% Pump Stations 74% 74% 75% 67% 62% 3.2.2 Break-In Percent Break-in percent illustrates the amount of emergency work (or reactive work) as a percent of total maintenance work (hours) in the process area. Typically, the break-in percent metric should track closely with the inverse of the proactive maintenance percent because one is a measure of the proactive maintenance program and the other a measure of unplanned outages or a reactive maintenance response (service requests with priority 40 and 50 level). Success in break-in percent is measured as a consistent trend downward over time. Break-in percentages for Plant No. 1 are shown in Table 3-5 and for Plant No. 2 in Table 3-6. There was an overall increase in break-in work and decrease in proactive work at the Plant No. 1 preliminary area due to Project P1-105 construction and equipment shutdown demands. Last year, the break-in percentage peaked at 55% in the preliminary area and many of the work orders were associated with odor control equipment. 2024 Asset Management Plan 124 The primary treatment area has shown relative stability in break-ins. Although there was a slight increase in FY 2022–2023 due to mechanical issues at the Waste Sidestream Pump Station (WSSPS) and the aging odor control facility, the trend is generally stable. Interplant area is down to 26% after an unexpected high number of break-ins in FY 2022–2023 due to vandalism in the area south of Plant No. 1. Utilities have shown an increasing trend, peaking at 36% in FY 2023–2024, indicating a growing number of break-ins with more than half of the issues happening at the Plant Water Pump Station. The remaining areas at Plant No. 1 have been showing stable trends with overall numbers less than 30%. At Plant No. 2, the data show an increase in break-in percent in areas with current construction projects and the need for shutdowns and tie-ins, including J-117B with 11% increase in the past 4 years. All process areas had break-in percentages in the acceptable range of below 28% at Plant No. 2, with trickling filters, utilities, and primaries showing improving trends. Table 3-5. Break-in Percent for Reclamation Plant No. 1 Process Area FY19/20 FY20/21 FY21/22 FY22/23 FY23/24 Preliminary 20% 24% 43% 29% 55% Primary 28% 23% 28% 38% 25% Interplant 16% 7% 0% 61% 26% Activated Sludge 14% 11% 8% 9% 15% Trickling Filters 10% 18% 36% 21% 26% Digesters 20% 27% 19% 24% 17% Solids Handling Facilities 22% 24% 20% 16% 27% Central Power Generation 11% 14% 23% 25% 20% Electrical Distribution 5% 10% 6% 7% 13% Utilities 21% 26% 21% 24% 36% Table 3-6.

Lido, Rocky Point, and College had the highest break-ins during the last year mainly due to instrumentation and alarm issues. Many aging pump stations, such as Bay Bridge, Seal Beach, Edinger, and Slater also had a high break-in percent that is reflective of their RUL and age. Bay Bridge, Seal Beach, and Edinger Pump Stations all have replacement projects that are in progress while Slater Pump Station rehabilitation is scheduled to start in a few years. Westside Pump Station also saw an increase in break-in percent. On average, 80% of the pump stations had a break-in percentage of less than 30%, marking an improvement during the past 5 years. 2024 Asset Management Plan 125 Table 3-7.

Electrical Emergency Work Orders Figure 3-2. Mechanical Emergency Work Orders The number of electrical “emergency” work orders and associated hours increased primarily due to electrical outages at the pump stations, and headworks power failures at both plants. Plant No. 1 Headworks observed a greater number of call outs due to the age of the facility. There were also a few electrical emergency call outs to support the rain events. The mechanical emergency work increased primarily due to Plant No. 1 headworks and primary treatment mechanical failures. One major emergency work at Plant No. 1 was the issues associated with Sunflower Pump No. 2 break and emergency repairs. The Plant No. 1 Grit Collector No. 2 repair was also a labor-intensive effort at Plant No. 1. In the first 6 months of 2024, Maintenance staff spent a lot of time addressing the broken shear pins at the primary clarifiers. On average, about 55% of emergency mechanical call backs were to support Plant No. 1. Electrical break-in/emergency work is expected to trend down as more electrical projects are implemented to replace or upgrade aging assets (e.g., P1-105). 0 50 100 150 200 250 300 Qt r 3 Qt r 4 Qt r 1 Qt r 2 Qt r 3 Qt r 4 Qt r 1 Qt r 2 Qt r 3 Qt r 4 Qt r 1 Qt r 2 Qt r 3 Qt r 4 Qt r 1 Qt r 2 Qt r 3 Qt r 4 Qt r 1 Qt r 2 Qt r 3 Qt r 4 Qt r 1 Qt r 2 2018 2019 2020 2021 2022 2023 2024 Electrical Emergency Work Orders - Call Back and Overtime Hours Total 0 50 100 150 200 250 300 350 Qt r 3 Qt r 4 Qt r 1 Qt r 2 Qt r 3 Qt r 4 Qt r 1 Qt r 2 Qt r 3 Qt r 4 Qt r 1 Qt r 2 Qt r 3 Qt r 4 Qt r 1 Qt r 2 Qt r 3 Qt r 4 Qt r 1 Qt r 2 Qt r 3 Qt r 4 Qt r 1 Qt r 2 2018 2019 2020 2021 2022 2023 2024 Mechanical Emergency Work Orders - Call Back and Overtime Hours Total 2024 Asset Management Plan 127 3.2.3 Maintenance Costs and Labor Hours OC San uses the maintenance costs and labor hours over time as trend indicators to indicate the number of resources devoted to reliably maintaining the process areas. Figure 3-3 shows maintenance costs (materials and services) per fiscal year broken down by process area at Plant No. 1. The thickening and dewatering facility at Plant No. 1 has the highest maintenance costs, with recurring issues such as thickening feed pumps losing efficiency and requiring repairs, and frequent leaks in the lube oil pumps of the dewatering centrifuges being among the costliest maintenance activities. The data indicate that there has been a large increase in maintenance costs at the Plant No. 1 Activated Sludge No. 2 since FY 2022–2023. In FY 2023–2024, regular PM activities at three AS aeration basins at AS2 facility (basins 14,15, and 16), the AS1 Clarifier 16 chain and flight crash, and the aeration basin mixer gearbox #3 installation were among the costliest maintenance activities. Figure 3-3. Graph of Maintenance Costs (Materials and Services) at Plant No. 1 Figure 3-4 shows Maintenance labor hours per fiscal year broken down by process area at Plant No. 1. The labor hours are high at the Plant No. 1 secondary facility because of the older equipment at AS1, which is scheduled for rehabilitation under Project P1-140. The labor hours are also high at the solids handling facility because the thickening and dewatering process has more complex equipment that requires more staff to operate and maintain. In FY 2023–2024, cleaning of the WSSPS wet well and replacing the seal on the PISB gate were the most labor-intensive activities in the primary area. In October 2023, the Barscreen No. 1 gearbox needed realignment, which required support from both the Mechanical and Electrical teams. Overall, the labor hour graph follows the same trend as material and services. $- $200,000 $400,000 $600,000 $800,000 $1,000,000 $1,200,000 $1,400,000 $1,600,000 $1,800,000 Plant No. 1 Maintenance Cost -Materials & Services FY19/20 FY20/21 FY21/22 FY22/23 FY23/24 2024 Asset Management Plan 128 Figure 3-4. Graph of Maintenance Labor Hours at Plant No. 1 Figure 3-5 and Figure 3-6 present the maintenance costs (materials and services) and labor hours per fiscal year, broken down by process area at Plant No. 2. Maintenance costs at Plant No. 2 were significantly higher in FY 2023–2024 for the primary treatment area, primarily due to the old A-Side Primary Clarifier Complex, which is being replaced by Project P2-98A, currently under construction. For example, the repairs at basin E accounted for approximately 37% of the total primary area costs. In the preliminary treatment area, lighting improvements at the headworks scrubber, and repairs to Barscreen #2 were among the most expensive maintenance activities. Last year, maintenance staff spent over 11,000 hours cleaning M&D pipes and manholes, which required the use of cranes and confined space entry. The AS facility also saw an increase in costs compared to the previous year. Major expenses included the rebuild of West RAS Pump 1 and the replacement of corroded pipes on the reactor deck. 0 1,000 2,000 3,000 4,000 5,000 6,000 7,000 8,000 9,000 Plant No. 1 Maintenance Labor Hours FY19/20 FY20/21 FY21/22 FY22/23 FY23/24 2024 Asset Management Plan 129 Figure 3-5.

Significant increases in labor and material costs occurred at the Slater, Seal Beach, and 15th Street Pump Stations. At Seal Beach, MSP Pump #1 was replaced, resulting in more than $83,000 in material costs. Additionally, all pressure transmitters were replaced in FY 2023–2024. Seal Beach Pump Station also shows high labor hours associated with the MSP #1 replacement and fan replacement at the pump station (Figure 3-8). This is one of OC San’s oldest pump stations. At the 15th Street Pump Station, the replacement of Pump #2 last year led to a substantial rise in maintenance costs. At Slater Pump Station, Pumps 1, 4, and 5 were removed and replaced, with these three pumps accounting for 80% of the total maintenance costs. Figure 3-8 shows an increase in labor hours at Crystal Cove Pump Station due to a new flowmeter installation and the MSP #1 check valve replacement. Figure 3-7.

Graph of Pump Station Maintenance Labor Hours 3.2.4 Collections Level of Service Results OC San monitors several levels of service goals pertaining to the collection system as a whole, but a select subset are relevant to the activities, goals, and effectiveness of asset management. This subset of collections level of service targets and results for the last 5 fiscal years are presented in Table 3-9. The level of service goals for SSO and odor complaints were achieved in FY 2023–2024, but the level of service goals for CCTV were not achieved due to unforeseen challenges as explained below. SSO events are primarily caused by debris accumulation from daily wastewater flows as well as root intrusion. Regular maintenance activities of Collections to clean sewers and the CCTV program serve to identify and prevent SSOs from occurring. Also refer to Section 3.4.2.2 for details on the root control blanket contract for further PM efforts. In FY 2023–2024, there were zero reported SSOs in the Collections System. Nuisance odors are actively managed by the ROCCS program through means of regular chemical dosing and caustic dumps at key locations, H2S monitoring, etc. The number of odor complaints are monitored to determine the effectiveness of chemical dosing, flow diversions, etc., to mitigate nuisance odors and prevent resulting corrosion damage to OC San’s Collection assets. Given the precision and effectiveness of the ROCCS program, the number of odor complaints has been below the level of service target in the past 5 fiscal years. The condition of assets in the collection system are monitored via the CCTV program, which inspects all gravity sewer and manhole assets every 5 years. OC San manages three CCTV contractors that provide inspection media and report to OC San with asset details as well as defects discovered per National Association of Sewer Service Companies (NASSCO) standards. OC San did not meet the level of service goal for CCTV inspections for both pipelines and manholes primarily due to the unexpected departure of its primary contractor Pro-Pipe for both the pipeline and manhole CCTV contracts.

OC San is actively procuring new services to restore the full capacity of OC San’s CCTV program and meet the level of service goals for FY 2024–2025. In November 2020, OC San started conducting routine inspections of the collection system manholes. 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. Now that about 2,579 (58%) of OC San’s manholes have been inspected since the start of the manhole CCTV program, we are able to accurately define future gravity sewer projects for manhole rehabilitation and replacement.

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 66,000 assets stored in Maximo®. This includes non-process-related assets such as HVAC equipment, lighting, mobile equipment, etc. For the assets associated with process and treatment, there are typically approximately 7,100 active PM work orders and on average 285 of those PM work orders are related to PdM activities. A current summary and breakdown of the PMs and PdMs are shown on Figure 3-9. Figure 3-9.

This accounts for materials and services only but is inclusive of both Reclamation Plants and the collection system. For historical maintenance expenditures, please refer to Chapter 4. Table 3-10. Projected Maintenance Costs Next Fiscal Year FY 2024–2025 Projected Maintenance Costs $26.6 million 3.4 Asset Management Program Accomplishments Another way to measure Asset Management Program performance and effectiveness is by exploring the accomplishments. The accomplishments identified in the following sections are important because they focus on both long-term planning and accomplishments that helped extend the useful life of critical assets, increase reliability, and reduce corrective maintenance and break-ins, allowing OC San to meet the key objectives of the program. 3.4.1 Condition Assessment Program Condition assessments are a key component of the Asset Management Program because they provide vital information with respect to the condition and life expectancy of critical plant and collections process structures and equipment. Condition assessments are planned in advance and often conducted during scheduled maintenance activities. The Asset Management Team completed approximately 27 different condition assessments during the last fiscal year, spending near $1 million using an outside consultant and contractor. Figure 3-10 provides annual expenditures on the two condition assessment contracts for the last 5 fiscal years. The overall expenditures show an increasing trend, illustrating Asset Management’s dedication to knowing the current condition of OC San’s major assets and performing incidental repairs following inspections to increase asset life and reliability. Figure 3-10. Condition Assessment Contract Expenditures $- $100,000 $200,000 $300,000 $400,000 $500,000 $600,000 2019-20 2020-21 2021-22 2022-23 2023-24 Conditional Assessment Contract Annual Expenditures Corrosion Engineer Contractor Support 2024 Asset Management Plan 134 Condition assessments identify deficiencies and the general condition of the assets, but more importantly provide recommendations for repairs or replacement and general timing of rehabilitation/replacement projects. Some condition assessments included incidental repairs following the assessment by the contractor that extended the useful life of the facility. The following are some critical condition assessments completed in the last fiscal year: • The Primary Clarifiers 6-31 center feed channel at Plant No.1 was taken out of service for the first time since construction finished almost 20 years ago. A condition assessment of the center feed channel along with incidental repairs were performed successfully during this outage. The channel is generally in good condition, some deficiencies were identified and repaired, such as a damaged T-lock at two locations and missing polymer or air diffusers at multiple locations. Additionally, 76 yards of grit were removed from the bottom of the channel. • The Primary Clarifiers 6-15 East Influent Channel at Plant No. 1 was taken out of service for a condition assessment, which found significant damages at two expansion joints at Basin 8 and Basin 12, causing leakages. Other major findings included T-lock damage and concrete spalling, as well as broken or missing air diffusers. The expansion joints, concrete and T-lock were repaired by the condition assessment program contractor, and Maintenance replaced the broken/missing air diffusers. • All of the trunkline pipes inside the M&D structure at Plant No. 1 are nearing the end of their useful life and experiencing accelerated corrosion. The SARI trunkline had a leak, which was repaired by welding steel plates on the outside of the pipe. A condition assessment of the Euclid trunkline, performed recently, found multiple holes at the top of the pipe and significant metal loss. The holes were patched with steel plates welded to the outside and Belzona applied to the inside of the pipe. This condition assessment and incidental repair prevented a potential failure and emergency project. A condition assessment for the Talbert trunkline is in the planning phase and will likely be completed before the end of October. The rest of the trunklines will follow, including a revisit to the SARI line. • A condition assessment at Sunflower Pump Station at Plant No. 1 was conducted and found significant coating failure, concrete degradation, corroded rebars, and compromised support beams in the two effluent channels. A maintenance project was initiated to install temporary support I-beams to strengthen the structure. This work was designed to be completed quickly so the pump station can be returned to operation before the wet season starts. A more permanent solution will be implemented in the next dry season. • The 72-inch and 90-inch (East) influent lines at Plant No. 1 are being demolished by P1-105 from the splitter box to the meter vault, creating the perfect opportunity for a condition assessment. The assessment found that the 72-inch pipe is in good condition while the 90-inch pipe has T-lock damage in multiple locations. The T-lock repair will be planned in the next year or two when the pipe can be taken out of service again. • A Plant No. 1 Thickening and Dewatering Facility Centrifuge chute assessment was conducted in 2024. The assessment found deformation of Chute No. 1. Incidental repairs were conducted to strengthen the chute, resulting in timely restoration of the centrifuge unit's operation. • Condition assessments were completed on the Primary Clarifiers J and N at Plant No. 2, to investigate alignment of the feedwell baffle and the condition of the circular drive respectively. The condition assessment included draining and cleaning of both basins and confined space entry to obtain photographs, take measurements, and collect other data to determine a resolution for issues identified by O&M. The assessment identified deficiencies in both clarifiers and the need for removal and replacement of the drive in Primary Clarifier N. • Condition assessments on anaerobic digesters are completed during the scheduled maintenance cleaning cycle to evaluate and extend the life of the assets when deficiencies are discovered. The condition assessment includes confined space entry, 2024 Asset Management Plan 135 corrosion assessment, sludge line cleaning and CCTV, concrete core sampling, and incidental repairs. This year, four digesters were cleaned and assessed, including Digesters 13 and 14 at Plant No. 1 and Digesters P and R at Plant No. 2. Incidental repairs were completed by the condition assessment contractor and Maintenance staff. • A Plant No. 2 PEPS discharge pipe condition assessment was conducted along with incidental repairs to replace the severely corroded pipe. After Pump #3 was removed for overhaul as part of the Maintenance Project MP2-010, the asset team did an assessment of the pump discharge header and found significant metal loss on the steel pipe wall due to corrosion. The team also found that the Pump #4 coupling installed during the overhaul was not the right type and not installed properly to cover the pipe diameter difference and the level offset, which caused water leaking. The condition assessment contractor was able to fabricate a new stainless-steel pipe to replace the corroded steel header for Pump #3 and successfully replaced the Pump #4 leaking coupling. The team will perform a condition assessment and replace the headers for Pumps #1 and #2 during the overhaul as required. • A condition assessment of the force mains at the Crystal Cove Pump Station, which was constructed in 1993, was conducted in March 2024 and found some apparent joint damage from a visual inspection within the pipes. To determine the extent of the potential corrosion, additional external testing was performed and found no significant thickness loss. The pump station and force mains are set to be rehabilitated under project 5-66 with construction to be completed in 2032. • MacArthur Pump Station was assessed in July 2024. The pump station was found to be in relatively good condition considering the pump station’s age. However, the wet well and various mechanical and electrical assets do require rehabilitation and will be addressed by Project 7-63, which is launching in 2024. 3.4.2 Collection System Assets OC San pump stations, force mains, and gravity sewer system are vital assets for conveying flow safely to the treatment plants. The Asset Management Program is continuously evaluating ways to improve the resiliency and reliability of the system while maintaining the level of service in all flow conditions. Some of the collection system initiatives and accomplishments are identified in the following sections. 3.4.2.1 Proactively Monitoring and Managing Operational and Defect Issues In the Gravity Collection system, there are a significant number of operational and structural defects that are isolated from current and future projects and are severe. Examples of isolated and severe operational defects include heavy root intrusion, infiltration runners and gushers, and large calcified deposits. Root intrusion is the main cause of SSOs in many sanitary sewer systems, and heavy infiltration over long periods of time can compromise soil support outside of the sewer pipe throughout the pipe zone leading to potential structural defects. Similarly, infiltration can also lead to the development of large calcified deposits that may block flows and prevent debris from passing downstream. Examples of isolated and severe structural defects include single or heavily clustered segments of broken pipe and holes with voids and/or soil visible. Broken pipe and holes are high risk given they are precursors to structural deformation and eventual collapse. Rather than create numerous small projects to address current and future isolated and severe asset issues, cost-effective and proactive maintenance-based approaches have been recommended as follows: • Root Control: Blanket contract to strategically apply herbicide with a foaming agent into select sewers for root control on an annual basis. The active ingredient in the root control treatment kills roots in the sewer (without killing the plant they originate from) and prevents regrowth typically for 2 to 3 years. 2024 Asset Management Plan 136 • Infiltration Control: Group isolated and severe infiltration into individual work packages for execution by Maintenance on-call contractors. Utilize the industrial cleaning Maintenance contract to remove large calcified deposits as-needed to prevent obstructions prior to rehabilitation. OC San is finalizing the scope of work packages and priority. • Isolated Structural Defect Repairs: Group isolated and severe structural defects into individual work packages for execution by Maintenance on-call contractors. OC San is finalizing scope of work packages and priority. Although the CCTV program inspects all collection assets every 5 years, there are limitations to the condition data that can be collected with CCTV equipment. Large-diameter sewers (greater than 42 inches in diameter) are not regularly cleaned and OC San does not have sufficient knowledge on existing debris buildup given CCTV cannot capture debris below the waterline. Therefore, the risk for an SSO due to debris accumulation or a high debris and ragging event at the treatment plant headworks facilities could be higher than past historical system performance would suggest. In response, OC San performed sonar inspections of over 5 miles of large-diameter sewers and inverted siphons to quantify debris and sediment and validated the cleansing state of sewers suspected to be non-cleansing; all sonar inspections were completed in June 2023. For the next steps, OC San is starting a new procurement to validate the accuracy of sonar inspections, validate the effectiveness of various cleaning methods, and analyze debris data for any trends. The work includes multiple rounds of cleaning and sonar inspections for select inverted siphons and gravity sewers as well as condition assessment and incidental repairs for the inverted siphons. The sonar validation project is expected to be completed in 2025. Additionally, a draft large-diameter cleaning program for inverted siphons and gravity sewers was completed in early 2024. This list of recommended large-diameter inverted siphons and gravity sewers to regularly clean will be finalized after the sonar validation project is completed. While many of these proactive activities increase current costs and potentially identify more defects, they result in better awareness of the true condition of OC San’s system, which allows for a more planned approach to maintaining assets. This allows for a more cost-effective CIP program while also reducing the risk of failures from unknown conditions. 3.4.2.2 Proactively Addressing Collection Pump Station Challenges Pump station reliability is critical to conveying wastewater to the treatment plants when gravity flow is not an option. In the past, emergency break-in work has been required due to the failure of critical assets such as isolation valves at some of the pump stations. Three valve replacement projects have recently been completed and two more valve replacement projects, which will replace aging and nonfunctioning valves at five different pump stations, are in progress. Project FRC-0018 is currently in design and will be replacing various valves at Lido, Crystal Cove, A Street, and 15th Street Pump Stations and replacing the wet well lining at A Street and 15 Street Pump Stations. The timing of these projects considers risk and criticality to prevent emergency work. Pump station force mains are challenging to maintain and inspect since they operate under pressure and are located underground. The force mains typically have limited access and require significant supplemental services to perform a safe and effective condition assessment (i.e., isolation and dewatering, temporary modification of pump station operations, excavation for access, etc.). The Asset Management Team has implemented a more robust program for force main inspections in which all force mains will be inspected on a predictable and recurring schedule. Please refer to the Force Main Summary and Inspection Plan in Chapter 2, Collection System Pump Station and Force Main Asset Management Summaries, for more information. In 2024, the Asset Management Team worked with Collections and contractors to plan out and perform the inspection of force mains at two pump stations, Crystal Cove and Edinger. The Asset Management Team will take lessons learned from the recent inspections to continue 2024 Asset Management Plan 137 planning inspections at other locations, which may pose challenges that require unique or innovative inspection methods. 3.4.3 Treatment Plant Projects and Planning Studies A major focus of the Asset Management Program is streamlining the replacement or repair of critical assets to extend RUL ahead of planned CIP projects. The Asset Management Team works in tandem with O&M to identify and create projects, provide construction bid documents, and manage project implementation of some maintenance projects. In addition, the Asset Management Team will take on important planning studies that look at ways to increase treatment reliability and safety and be a good steward of the environment. Here are some projects that were driven and led by the Asset Management and Maintenance Teams: • Several of our critical pumping systems are equipped with VFDs that have become obsolete and can no longer be maintained properly. The Asset Management Team is tracking all major VFDs and working on creating a VFD replacement program to streamline replacement. Currently, projects FE19-08, FR1-0011, and MP2-016, are in construction and future CIP projects will replace obsolete VFDs at various locations at Plant Nos. 1 and 2 and the Pump Stations. • Project PS22-02, Onsite Oxygen Generation Feasibility Study at Plant No. 2, was completed in 2024 to evaluate whether an onsite oxygen generation system should be implemented to provide better oxygen supply reliability to meet the High-Purity Oxygen-Activated Sludge Plant demands in the next 20 years. Currently, OC San uses LOX delivery and storage, but there was a shortage of LOX during the pandemic and the cost of LOX is rising significantly. Based on the PS22-02 recommendations, a CIP project will be developed to install a safe and reliable onsite oxygen generation system. • The trickling filter rotary distributor assemblies at the Trickling Filter Solids Contact Facility at Plant No. 2 had reliability issues due to major equipment failures. In the fall of 2023, MP2-005 completed the purchase and installation of the TF-A and TF-B rotary distributor assemblies to replace the failed units. MP2-019 is in progress to replace the TF-C rotary distributor assembly in 2024 and is anticipated to be complete by the end of October. By the start of wet weather season, Plant No. 2 will have all three trickling filter rotary distributor assemblies replaced, providing reliable secondary treatment of reclaimable flows for the GWRS. • The A-side Primary Clarifiers, originally constructed in the 1960s, are unreliable due to age and deterioration or failure of existing components such as the basin structure, geodesic dome, baffle components, and rotating mechanisms. Several maintenance projects were completed to address these issues and provide short-term reliability of the existing A-Side Primary Clarifiers until they are replaced by Project P2-98A, which is under construction with an estimated completion in 2027. Project FE23-09 will provide rehabilitation of corroded sections of the rotating mechanisms and feed well for Primary Clarifiers F and G. The design was fast tracked and construction has begun. • The Grit Basins at Plant No. 2 have experienced multiple power and control cable failures that put the entire Grit Basin system at risk of becoming nonoperational. An urgent project, MP2-013, along with multiple work orders by Maintenance, were executed to have temporary cables installed above ground to bring the Grit equipment back online. Project P2-141 has also been fast-tracked to replace the cables permanently. • P1 and P2 Digester Gas Dryer Replacement Project, FE23-01, will replace the refrigerated digester gas drying systems at both plants to ensure that high-quality compressed digester gas is delivered to the Cen Gen engines for subsequent reliable energy production purposes. The dryers are located downstream of the digester gas compressors and are responsible for reducing the dew point and removing water from the digester gas. These dryers are an important and critical part of the gas handling system as a whole, and integral to the reliable operation of the Interplant Gas pipeline and engine 2024 Asset Management Plan 138 systems alike. In addition, Project FE24-02 will be replacing the heat exchanger moisture separator at Plant No. 1 that has reached the end of its useful life and needs replacement. Both projects will start construction in FY 2024–2025. • Plant No. 2 PEPS pumps are aging, and a previous wet well condition assessment identified corrosion in the pump discharge line. A maintenance project successfully completed a Pump #4 factory condition assessment and subsequent overhaul in November 2022. MP2-0010, is in progress to overhaul the remaining three pumps, and a Pump #3 overhaul will be complete in 2024. • 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. Project J-135B recently completed top-to-bottom overhauls of Engines No. 1 and No. 3 at Plant No. 1 and Engine No.1 at Plant No. 2. The J-135B project and its subsequent Project J-135C will continue to overhaul the remaining engine generator set at Plant No. 1 and the remaining four engine generator sets at Plant No. 2 in the next 5 years. Planning study PS20-04, completed in 2023, showed that OC San’s existing engines can be reliably maintained for the next 10 plus years. To develop a long-term plan for the Cen Gen Facilities, the Energy and Digester Gas Master Plan (EMP), PS21-04, was conducted from 2022 to 2024. This study evaluated viable alternatives for energy production and digester gas management based on emerging technologies, market conditions, and potential permitting constraints. The EMP study recommended that at this time, OC San should continue to operate Cen Gen and the associated interplant pipeline until the end of its useful life or changes in market conditions drive replacement of Cen Gen. The outcome of this EMP study is not a single recommendation, but an actionable 5- to-10-year Cen Gen replacement roadmap. Given the rapidly evolving energy market in the U.S., and California in particular, the study recommended OC San revisit and update this EMP and its recommendations in approximately 5 years. 3.5 Asset Management Program Improvement Opportunities The Asset Management Team continues to look at ways to improve the Asset Management Program. To facilitate continuous improvement and move to a more data-driven program, the Team has created a Digital Asset Management Study. The key objectives of this study are to: • Allow available asset data to be analyzed more quickly and efficiently with the creation of business intelligence dashboards. • Enhance collaboration and data sharing between Maintenance and Engineering Teams to support both short-term and long-term planning through business intelligence (BI) dashboards. • Provide a simpler and more robust means to convey asset management information in the AMP and to executive leadership. • Improve asset planning and prioritization of projects by development of a risk framework. • Find additional Program improvement opportunities based on industry trends and new technology. OC San has a lot of asset data available through various platforms, programs, and systems to assess OC San’s major assets. One of the challenges is being able to utilize all that data more efficiently in one location or platform. The Digital Asset Management Study will create asset management and maintenance KPI BI dashboards, providing real-time asset information for improved and defensible decision making and asset planning. Developing a risk assessment framework will also improve asset management planning and project prioritizing with the goal of having average risk scores for every project that take into account consequences of failure. The following list describes the future Asset Management Program improvement opportunities, both 2024 Asset Management Plan 139 short-term and long-term, and how the new Digital Asset Management Study will address many of these improvement opportunities. Condition Assessments: • Track future condition assessments and proactively plan ahead with Operations for assessments that require process interruptions. STATUS: In progress and led by internal staff. • Understand the condition and RUL of all of OC San’s major assets. STATUS: In progress and led by internal staff. Remaining Useful Life: • Consider ways to improve the accuracy of RUL in addition to the Condition Scoring Guidelines already created. STATUS: In progress via Digital Asset Management Study. • Create more condition scoring categories in the 1- to 10-year range as RUL accuracy improves over time. STATUS: Future goal after completion of Digital Asset Management Study. Asset Registries: • Ensure all pertinent asset information is included in the Asset Registries, including having a plan to address all assets with a RUL fewer than 10 years. STATUS: Completed. • Determine the best way to track major assets in the long term such that the Asset Registries are compatible with BI dashboards.

The Asset Management Program must always consider the mission statement of “delivering the required level of service, at the lowest life cycle cost, with an acceptable level of risk.” This page left blank intentionally 2024 Asset Management Plan 141 4 Budgetary Considerations The AMP 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 developed a 20-year CIP, creating project plans for forecasted rehabilitation, replacement, improvements, or expansion for the collection system and treatment plants. The CIP budget is evaluated and updated on a yearly basis as new information becomes available. 4.1 Capital Improvement Expenditures The FY 2024–2025 Budget Book, adopted in June 2024, includes updates to the current 20-year CIP outlay. Figure 4-1 shows the 20-year CIP outlay, which includes current and projected future CIP projects. The FY 2024–2025 CIP Outlay is $253.5 million and is further divided into process categories, as shown on Figure 4-2. Liquid treatment, support facilities, and collection facilities are the primary areas where the FY 2024–2025 CIP outlay will be spent. For liquid treatment, Project No. P1-105, Headworks Rehabilitation at Plant No. 1, and Project No. P2-98A, A-Side Primary Clarifiers Replacement at Plant No. 2, are expected to be the largest expenditures of $41 million and $19.5 million, respectively, in FY 2024–2025. For support facilities, Small Construction Projects Program, is the biggest driver with $26 million in FY 2024–2025. Lastly, for collection facilities, Project No. 3-67, Seal Beach Pump Station Replacement, and Project No. 7-65, Gisler-Red Hill Interceptor and Baker Force Main Rehabilitation, comprise nearly two-thirds of collections CIP spending at $14 million and $26 million, respectively. Figure 4-1. 20-Year CIP Outlay 2024 Asset Management Plan 142 Figure 4-2. FY 2024–2025 CIP Outlay by Process – $253.5 Million 4.2 Maintenance Expenditures 4.2.1 Five-Year Historical Maintenance Expenditures Figure 4-3 and Figure 4-4 show the historical actual spent versus budgeted operational and maintenance expenditures for the treatment plants and collection system, respectively. • The treatment plant expenditures include maintenance services and materials (budget objects 54010 and 54020). • The collection system expenditures include maintenance services and materials (budget objects 54010, 54020, and 53180). • These costs represent the O&M costs of fixed assets, including operationally funded repair/replacement projects. A variety of factors and variables are not reflected in the development of the budget. As a result, some years reflect higher expenditures than budgeted. These factors include but are not limited to the following: • Annual inflation rates • Manufacturing cost increases (which are also affected by increases in labor, raw material demand, fuel, chemicals, fees to expedite due to long lead times) • Supply chain cost increases • Geopolitical events • Additional maintenance expenses that were unforeseen or unplanned but include necessary repairs or procurements 2024 Asset Management Plan 143 Figure 4-3. Five-Year Historical Maintenance Costs for Treatment Plants Figure 4-4. Five-Year Historical Maintenance Costs for Collection System 2024 Asset Management Plan 144 4.2.2 Three-Year Look-Ahead Maintenance Expenditures Table 4-1 shows operationally funded projects identified to date and includes the projected annual expenditures over the next 3 years. It is likely future projects and costs will fluctuate based on the condition of assets as they age. The projects are grouped by location (Collection System, Plant No. 1, Plant No. 2, and Joint), and then sorted by the project start fiscal year. The list encompasses projects identified as of September 16, 2024, with the following criteria: • Estimated construction cost is equal to or greater than $50,000 and has projected expenditures within the next 3 years. • Projects on the list represent expenditures that are operationally funded. • Some projects that are similar in nature have been combined into a single project for more efficient project execution. • Blanket purchase order contracts are not included. 2024 Asset Management Plan 145 Table 4-1.

BENTHOS – The community of organisms, such as sea stars, worms, and shrimp, which live on, in, or near the seabed, also known as the benthic zone. BIOCHEMICAL OXYGEN DEMAND (BOD) – The amount of oxygen used when organic matter undergoes decomposition by microorganisms. Testing for BOD is done to assess the amount of organic matter in water. BIOGAS – A gas that is produced by the action of anaerobic bacteria on organic waste matter in a digester tank that can be used as a fuel. BIOSOLIDS – Biosolids are nutrient rich organic and highly treated solid materials produced by the wastewater treatment process. This high-quality product can be recycled as a soil amendment on farmland or further processed as an earth-like product for commercial and home gardens to improve and maintain fertile soil and stimulate plant growth. CAPITAL IMPROVEMENT PROGRAM (CIP) – Projects for repair, rehabilitation, and replacement of assets. Also includes treatment improvements, additional capacity, and projects for the support facilities. COLIFORM BACTERIA – A group of bacteria found in the intestines of humans and other animals, but also occasionally found elsewhere, used as indicators of sewage pollution. E. coli are the most common bacteria in wastewater. COLLECTIONS SYSTEM – In wastewater, it is the system of typically underground pipes that receive and convey sanitary wastewater or storm water. CERTIFICATE OF PARTICIPATION (COP) – A type of financing where an investor purchases a share of the lease revenues of a program rather than the bond being secured by those revenues. CONTAMINANTS OF POTENTIAL CONCERN (CPC) – Pharmaceuticals, hormones, and other organic wastewater contaminants. DILUTION TO THRESHOLD (D/T) – The dilution at which the majority of people detect the odor becomes the D/T for that air sample. GREENHOUSE GASES (GHG) – In the order of relative abundance water vapor, carbon dioxide, methane, nitrous oxide, and ozone gases that are considered the cause of global warming (“greenhouse effect”). GROUNDWATER REPLENISHMENT SYSTEM (GWRS) – A joint water reclamation project that proactively responds to Southern California’s current and future water needs. This joint project between the Orange County Water District and OCSD provides 70 million gallons per day of drinking quality water to replenish the local groundwater supply. LEVEL OF SERVICE (LOS) – Goals to support environmental and public expectations for performance. N-NITROSODIMETHYLAMINE (NDMA) – A N-nitrosamine suspected cancer-causing agent. It has been found in the GWRS process and is eliminated using hydrogen peroxide with extra ultra-violet treatment. NATIONAL BIOSOLIDS PARTNERSHIP (NBP) – An alliance of the NACWA and WEF, with advisory support from the EPA. NBP is committed to developing and advancing environmentally sound and sustainable biosolids management practices that go beyond regulatory compliance and promote public participation to enhance the credibility of local agency biosolids programs and improved communications that lead to public acceptance. PER- AND POLYFLUOROALKYL SUBSTANCES (PFAS) – A large group (over 6,000) of human-made compounds that are resistant to heat, water, and oil and used for a variety of applications including firefighting foam, stain and water-resistant clothing, cosmetics, and food packaging. Two PFAS compounds, perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) have been the focus of increasing regulatory scrutiny in drinking water and may result in adverse health effects including developmental effects to fetuses during pregnancy, cancer, liver damage, immunosuppression, thyroid effects, and other effects. PERFLUOROOCTANOIC ACID (PFOA) – An ingredient for several industrial applications including carpeting, upholstery, apparel, floor wax, textiles, sealants, food packaging, and cookware (Teflon). PERFLUOROOCTANESULFONIC ACID (PFOS) – A key ingredient in Scotchgard, a fabric protector made by 3M, and used in numerous stain repellents. PLUME – A visible or measurable concentration of discharge from a stationary source or fixed facility. PUBLICLY OWNED TREATMENT WORKS (POTW) – A municipal wastewater treatment plant.
