As we launch our 2025 Strategic Plan, we do so with a renewed commitment to resource recovery, resilience, innovation, service, and equity—core pillars that guide our organization. These values ensure that OC San remains adaptable, visionary, and responsive. The Strategic Plan is the foundation of our three-year planning and execution cycle. Informed by shifts in regulations, emerging technologies, infrastructure needs, and the changing expectations of those we serve, this plan charts a clear path forward. We are leveraging new technologies, data-driven decision-making, and sustainable practices to strengthen reliability, improve efficiency, and expand opportunities for resource recovery. It defines our service levels across 16 policy areas and provides direction for budgeting, capital planning, and operations. This process is also an opportunity for renewed leadership and unity. With a Board of Directors that sees a significant number of new members every two years, the Strategic Plan gives each Board the ability to shape OC San’s future while continuing the momentum built by those who came before. By embracing innovation and fresh perspectives, our Board and staff ensure that OC San continues to grow stronger with every planning cycle. Thank you to our past and current Board Members for their vision and leadership. Your contributions have shaped an organization that continues to innovate, improve, and adapt in service to the people of Orange County. With the guidance of this 2025 Strategic Plan, OC San will continue to rise to meet tomorrow’s challenges—delivering results our community can count on and building more resilient future for generations to come. Sincerely, Robert Thompson General Manager 6 | Strategic Plan — 2025 7 | Strategic Plan — 2025 Executive Summary The Orange County Sanitation District (OC San) is driven by its mission to protect public health and the environment by providing reliable, cost-effective wastewater and resource recovery services. The 2025 Strategic Plan is the guiding framework that aligns the priorities of the Board of Directors, staff, and community to meet emerging challenges with forward-thinking solutions. OC San’s strategic planning is based on a three-year cycle and a four-step management process that ensures continuity, accountability, and progress toward long-term goals. This process includes: 1. Strategic Planning – Establishing a shared vision and identifying our capacity (people and assets) to fulfill our mission. 2. Budget Development – Allocating resources and setting tactical plans aligned with the adopted Strategic Plan. 3. Implementation – Executing the day-to-day operations and delivering essential services to our stakeholders. 4. Performance Reporting – Measuring and reporting on progress, service levels, and goal attainment. This continuous improvement model fosters accountability and innovation, ensuring OC San stays true to its mission while adapting to evolving community needs, regulatory requirements, and technological advancements while maintaining organizational stability—even through Board and staff transitions. The 2025 Strategic Plan builds upon the foundation of the 2021 and 2023 plans, reaffirming the direction while incorporating meaningful updates. Based on extensive input from the Board and staff, OC San refined its strategic policy framework, which is organized into four key focus areas and now includes 16 policy areas (an increase from 15) with the addition of Potable Water Salinity Control. The inclusion of Potable Water Salinity Control and Cybersecuity and Artificial Intelligence underscores how innovation is central to advancing the mission. Strategic Focus Areas and Policy Topics Business Principles • Budget Control and Fiscal Discipline • Asset Management • Cybersecurity and Artificial Intelligence • Property Management • Organizational Advocacy and Outreach Environmental Stewardship • Energy Independence • Climate and Catastrophic Event Resiliency • Food Waste Treatment • Environmental Water Quality, Stormwater Management, and Urban Runoff • Potable Water Salinity Control (New) Wastewater Management • Chemical Sustainability • Biosolids Management • Constituents of Emerging Concern • Water Reuse Workplace Environment • Resilient Staffing • Safety and Physical Security Throughout the year, OC San engaged the Board of Directors in reviewing the prior plan and updating each policy area. The result is a set of clear policy statements, background context, current conditions, and refreshed initiatives that are measurable and actionable. These initiatives will guide the development of the next steps in the planning cycle, the Budget and two General Manager’s Work Plans. The Board received updates on Levels of Service (LOS), Core Values, and the Risk Register. LOS ensures OC San’s commitment to reliable day to day service, Core Values promote innovation and collaboration, and the Risk Register identifies opportunities and mitigates critical risks to operations. By building on the strengths of the existing framework and proactively addressing new challenges, the 2025 Strategic Plan ensures OC San continues to lead with purpose, resilience and innovation. OC San is prepared to meet the needs of today and to reshape its staff and facilities for generations to come.

BUSINESS PRINCIPLES Budget Control and Fiscal Discipline Policy Statement The Orange County Sanitation District (OC San) has practices and safeguards in place to ensure its long-term fiscal stability. These provide direction so that OC San’s finances are managed in a manner that will continue to support the daily collection and treatment of wastewater; meet the mission of the organization; maintain our AAA Bond Rating; ensure a responsible budget consisting of Revenues, Operating Expenditures, Capital Improvement Program (CIP), Debt Service; and establish reserves necessary to meet known and unknown future obligations. OC San has established Fiscal Policies and Reserve Criteria, which are included in the budget, and separately adopted Investment and Debt Policies. These policies set the guidelines for planning the cashflow of OC San and have helped to stabilize the rates that our residents pay. Initiatives • Use established resources, along with developing and implementing additional resources to assist OC San staff in tracking and monitoring expenditures to ensure smooth business operations while maintaining budgetary control. • Maintain a fiscally responsible financial plan that is based on long-term planning which supports stable rate setting and a pay-as-you-go philosophy for operating and capital expenditures. • Leverage the centralized training program to provide targeted training opportunities for employees to remain current with financial best practices and OC San fiscal policies and procedures. • Monitor the long-term debt program and continually assess market conditions to identify possible opportunities to reduce outstanding debt balance and term, while maintaining a AAA rating. Maintain reserve levels within policy guidelines, while optimizing the use of available funds to finance capital programs and ensure a balanced budget. Asset Management Policy Statement The Orange County Sanitation District (OC San) will assess and manage the collection and treatment plant systems and assets to improve resilience and reliability while lowering lifecycle costs. This will be accomplished through adaptive operation, coordinated maintenance and condition assessment, and planned capital investment. Staff will balance maintenance, refurbishment, and replacement strategies to maximize useful life, system availability, and efficiency. 14 | Strategic Plan — 2025 15 | Strategic Plan — 2025 Initiatives • Continue developing an annual Asset Management Plan documenting the condition of the collection system and treatment plants, and upcoming maintenance or capital projects. • Coordinate the efforts of operations, collections, mechanical maintenance, electrical maintenance, instrument maintenance and engineering through process area teams to assure OC San’s resources are focused on the high priority work functions. • Identify critical collections and plant assets that have long lead times for parts and replacement and mitigate procurement risks and impacts to collections and plant resiliency based on market conditions. • Maintain a 20-year forecast of all CIP projects needed to maintain or upgrade OC San’s in assets on a prioritized risk basis to establish rate structures. • Leverage asset information and tools to define the remaining useful life of assets. Cybersecurity and Artificial Intelligence Policy Statement The Orange County Sanitation District (OC San) is committed to building and maintaining resilient, secure, and ethically governed technology systems. This includes a robust cybersecurity posture and the responsible adoption of Artificial Intelligence (AI), including both generative AI and advanced operational AI. As OC San advances its digital transformation, the agency must ensure that its technology practices safeguard data, systems, and operations, while also leveraging innovation to improve service delivery, operational efficiency, and decision-making.

Potable Water Salinity Control Policy Statement The Orange County Sanitation District (OC San) will partner with other Public Agencies in our watershed to reduce the salinity of the potable water supply of our stakeholders. OC San will use its existing facilities, including its Ocean Outfall, to safely dispose of naturally occurring dissolved solids, or salts, which may be attributed to water reuse, imported water, brackish groundwater, or past agricultural activities. Initiatives • OC San will continue to invest in the maintenance of the Ocean Outfall system to assure long-term viability. • OC San will maintain a National Pollution Discharge Elimination System Permit that supports treatment operation and safe outfall disposal of Groundwater Replenishment System reverse osmosis concentrate and dissolved solids from the Santa Ana Watershed. • OC San will support the Santa Ana Watershed Project Authority strategic planning process to support watershed salt management through 2046 and beyond. 20 | Strategic Plan — 2025 21 | Strategic Plan — 2025 on constituents (or contaminants) of emerging concern (CECs) at the federal, state, and regional levels. Staff will obtain and maintain current knowledge on CECs under regulatory consideration, including occurrence, analytical methods, regulations, and treatment to support OC San’s mission and regulatory compliance. Initiatives • OC San will continue to actively engage water and wastewater stakeholders to stay abreast of the scientific progress and any potential operational and financial impacts of CECs and provide timely briefings to OC San’s Executive Management Team and Board of Directors to facilitate informed decision making. • OC San will continue to develop capacity to identify, detect, quantify, and characterize CEC sources throughout the service area and treatment process to promote source reduction, treatment effectiveness, communication of credible risks, and responsible reuse and disposal. • OC San will proactively establish internal expertise and develop laboratory capability to research the potential impact of CECs on beneficial reuse of water and biosolids. OC San will use science-based knowledge to help shape CEC legislation and regulations to protect the public health and environment. • In the absence of promulgated regulatory limits for specific CECs, OC San will work with regulatory agencies to establish interim source control measures to safeguard its water and biosolids reuse initiatives and ocean discharge against potential adverse impacts. If OC San is regulated, OC San will regulate upstream. Water Reuse Policy Statement The Orange County Sanitation District (OC San) will seek to beneficially reuse all reclaimable water for potable, industrial, irrigation and environmental uses. Initiatives • Support Groundwater Replenishment System and maximize reclaimable wastewater availability to OCWD. • Support Green Acres project water production to provide reclaimed water for industrial and irrigation uses. WASTEWATER MANAGEMENT Chemical Sustainability Policy Policy Statement The Orange County Sanitation District (OC San) has a need to use chemicals in its treatment process to improve plant performance, reduce odor and corrosion potential, and meet its regulatory requirements. These commodity chemicals are provided by outside vendors through the purchasing process. Some of these chemicals are subject to price swings due to market condition changes such as energy cost impacts, raw material cost changes, commercial competition changes, and transportation cost volatility. OC San will identify chemicals key to its operation, investigate the market risks for those chemicals and devise strategies to mitigate identified risks to availability and pricing. Initiatives • Reduce the exclusive reliance on particular chemicals and/or individual vendors to establish flexibility while accomplishing operational objectives. • OC San has evaluated the potential for generating pure oxygen onsite and will be initiating a Capital Improvement Program project to develop and maintain an oxygen generation facility, reducing reliance on the delivery of liquid oxygen by truck. Biosolids Management Policy Statement The Orange County Sanitation District (OC San) will remain committed to a sustainable biosolids program and will continue the beneficial reuse of biosolids in accordance with Resolution No. OC San 13-03 and the 2017 Biosolids Master Plan. Initiatives • Assess Deep Well Injection to handle up to 100 percent of OC San’s biosolids production as a sustainable and diverse biosolids management strategy with the benefit of carbon sequestration and reduction in transportation costs and impacts. • Partner with other POTW agencies to conduct a feasibility study on a proposed regional biosolids facility in the Inland Empire to address rising costs, regulatory changes, and disposal challenges. • Continue to engage with local, state, and federal agencies to ensure that biosolids will continue to be safely and legally used as a soil amendment. • Continue working with OCWR to explore regional biosolids management opportunities as well as local solutions to meet SB 1383’s organics diversion mandates, with an emphasis on in-county biosolids utilization, composting, food waste co-digestion, and biogas production. • Implement new mesophilic digesters at Plant No. 2, with the option to upgrade to thermophilic, to improve OC San’s operational resiliency against seismic events while enhancing biosolids quality and marketability.

These provide direction so that OC San’s finances are managed in a manner that will continue to support the daily collection and treatment of wastewater; meet the mission of the organization; maintain our AAA Bond Rating; ensure a responsible budget consisting of Revenues, Operating Expenditures, Capital Improvement Program (CIP), Debt Service; and establish reserves necessary to meet known and unknown future obligations. OC San has established Fiscal Policies and Reserve Criteria, which are included in the budget, and separately adopted Investment and Debt Policies. These policies set the guidelines for planning the cashflow of OC San and have helped to stabilize the rates that our residents pay. Background OC San’s annual budget for Operating, Capital, and Debt Service expenses is approximately $600 million. OC San maintains all physical assets at a level adequate to meet its mission, protect OC San’s capital investment, and to minimize future maintenance and replacement costs. OC San maintains budgetary and accounting practices that balance the budget cycle without deferring costs to future budgets. These efforts are supported by OC San’s pay-as-you-go policy for its capital projects and expenditures. OC San focuses its fiscal policy around seven distinct areas, (1) Revenues, (2) Operating Budget, (3) CIP, (4) Long-Term Debt, (5) Reserves, (6) Investments, and (7) Accounting, Auditing, and Financial Reporting. These areas are reviewed, updated annually, and described as follows: 1) Revenues OC San’s revenues come from three general areas: Fees and Charges, Property Taxes, and other smaller revenue sources. Because revenues are sensitive to both local and regional economic conditions, revenue estimates are conservative. Staff estimates annual revenues by an objective, analytical process that utilizes trends, judgment, and statistical analysis as appropriate. Property tax revenues of OC San are first dedicated to debt service. OC San sets fees and user charges at a level that fully supports the total direct and indirect costs of operations, capital improvements, and debt service requirements not covered by property taxes and reserves. 2) Operating Budget The budget is used as a fiscal control device as well as a financial plan. Budget preparation and monitoring are performed by each division within OC San at the organizational level to ensure accountability and control. An annual operating budget is developed by Financial Management and the respective divisions, conservatively projecting expenditures for the current and forthcoming fiscal years. During the annual budget development process, the existing programs are examined to assure removal or reduction of any services or programs that could be eliminated or reduced in cost. Annual budgets provide for adequate repair and maintenance of facilities and equipment. Current operating expenditures are supported by current revenues. 3) Capital Improvement Program OC San makes all capital improvements in accordance with an adopted and funded CIP. OC San maintains a current Asset Management Plan and a twenty-year plan for capital improvements, including design, construction, and OC San staff costs. All capital projects approved in the annual budget are approved for the budgeted amounts through the completion of the project. The Board of Directors approves both the individual project total budget and the projected cash outlays for all capital projects. Staff identifies which capital projects may have a significant impact to ongoing operating and maintenance costs, staffing impacts and estimates the impact as the project is developed. Staff coordinate the development of the CIP budget with the development of the operating budget. All operations and maintenance resources required to implement the CIP have been considered and appropriately reflected in the operating budget for the year the project is to be implemented. Cost tracking for components of the project is updated quarterly to ensure project completion against budget and established timelines. 4) Long-Term Debt OC San maintains a Board of Directors adopted Debt Policy. Before any new debt is issued, the impact of debt service payments on total annual fixed costs is analyzed. Proceeds from long-term debt cannot be used for current on-going operations. OC San maintains a AAA credit rating from Moody’s, S&P, and Fitch. 5) Reserves OC San has a Board of Directors Reserve Policy which governs the establishment of our reserve level and the use of those funds. To ensure an adequate and diverse reserve policy, we have established seven different criteria. These criteria ensure that OC San will have sufficient funds for debt covenants, operating expenditures, and debt service payments prior to receiving our revenue from the county, operating contingency, rehabilitations and refurbishment, CIP contingency, and self-insurance for catastrophic loss. Any amount more than these criteria are used to fund capital projects on a pay-as-you-go basis. 6) Investments OC San annually submits an investment policy to the Board of Directors for review and adoption. The investment policy emphasizes safety and liquidity before yield. OC San contracts with an Investment Manager to manage its portfolio in accordance with State Code and the investment policy. 7) Accounting, Auditing, and Financial Reporting OC San’s accounting and financial reporting systems are maintained in conformance with accepted accounting principles. Quarterly financial reports are submitted to the Board of Directors and made available to the public. Monthly Operating Budget Reports are compiled, analyzed, and distributed to each division. Financial Management staff meet quarterly with each division to review the operating expenditure and with the Project Management Office to review the CIP progress. An annual audit is performed by an independent public accounting firm with the subsequent issue of an official Annual Comprehensive Financial Report, including an audit opinion and a management letter. Various internal audits are undertaken each year under the direction of the Audit Ad Hoc Committee to ensure adherence to policies, processes, and procedures. 28 | Strategic Plan — 2025 29 | Strategic Plan — 2025 Current Situation 1) Revenues Most of OC San’s revenue is generated by user fees and charges. This category accounts for approximately 70 percent of OC San revenue in a year. Currently, OC San fees are in the lower third of its comparison agencies. After completing a rate study, a new five-year rate schedule was adopted by the Board of Directors in March 2023. OC San receives a share of the basic property tax levy proportionate to what was received in the 1976 to 1978 period, less $3.5 million allocated to school districts. These funds make up approximately 22 percent of the total revenue for the year. Other Revenue includes Interest Earnings, Intra-District Transfers, and small revenue sources that make up the remaining eight percent of the annual revenue. Budget Expenditures OC San adopts a biennial budget with an update in the second year of the adopted budget. The annual budgeted expenditures are approximately $600 million. This document lays out the framework of OC San’s activities during the upcoming fiscal year and serves as a source of information for the Board of Directors, our ratepayers, investors, and our employees. This budget includes the operational, capital and debt service expenditure necessary to cost-effectively support our mission and execute the Strategic Plan adopted by our Board of Directors. OC San has received the Government Finance Officers Association Distinguished Budget Presentation Award for the last 29 years. 2) Operating Budget OC San’s Operating Budget is the financial plan and fiscal control mechanism for the 25 divisions that comprise the six departments. The Operating Budget accounts for the costs to operate, maintain, and manage OC San’s two treatment plants, 15 pump stations, and over 380 miles of collection systems. Outside of salaries and benefits, the largest expenditure categories are repairs and maintenance and operating supplies. The budget preparation process is collaborative among the divisions, departments, Finance, and upper management. The General Manager and Assistant General Manager met with each of the departments to ensure their budget proposals were prudent and cost-effective. This process assists to develop a comprehensive budget for OC San that meets the needs of the organization and is fiscally responsible. 3) CIP OC San’s CIP has evolved over time. It began by focusing on creating the initial infrastructure of the collections and treatment system, shifted to expanding capacity, and now our focus is on aging infrastructure, incorporating climate resiliency, seismic risk, and maximizing resource recovery in every project we execute. There is $3.5 billion in planned capital projects over the next ten years. The CIP is supported by the Asset Management Plan, which is updated annually and provides a comprehensive analysis of the condition and capacity of OC San’s wastewater infrastructure. The Asset Management Program continuously validates and updates the projects that are within the CIP. Current and near-term future projects are validated annually to ensure an accurate schedule, scope, and budget. 4) Long-Term Debt OC San’s long-term debt fiscal policy restricts long-term borrowing to capital improvements that cannot be financed from current revenue. Before any new debt is issued, the impact of debt service payments on total annual fixed costs will be analyzed. OC San has $606 million in outstanding debt. No new money debt issuances are planned. The debt issuances are regularly reviewed and evaluated for potential savings through refinancing. All existing debt is scheduled to be paid off by 2040. 5) Reserves OC San conducted an in-depth review of the agency’s reserve policies. This review included a survey of the reserve policies of 23 other public agencies and is periodically updated. It serves as a tool to assist in the evaluation of the underlying economic reasons supporting OC San’s reserve policies. There are seven distinct reserves criteria which together comprise OC San’s reserve fund target. These criteria are cash flow, operating contingency, capital improvement, catastrophic loss/self-insurance, replacement and refurbishment, debt service, and accumulated funds. Collectively, these individual criteria require a minimum average reserve amount of approximately $580 million a year over the current ten-year cash flow forecast. This reserve amount, while significant, totals less than five percent of the replacement value of our $15.7 billion in assets. 6) Investments OC San invests public funds in a manner which ensures the safety and preservation of capital while meeting reasonably anticipated operating expenditure needs, achieving a reasonable rate of return, and conforming to all state and local statutes governing the investment of public funds. OC San uses a bank checking account and sweeps account for its daily transactions. Liquidity needs are met through funds invested in the Local Agency Investment Fund managed by the State Treasurer’s Office. Most of OC San’s investments are separated into two distinct portfolios, Long-term and Short-term, with a primary focus on the Long-term portfolio, which are managed by an outside investment manager. Monthly, quarterly, and annual reporting and review mechanisms are in place. 7) Accounting, Auditing, and Financial Reporting An audit of the books, financial records, and transactions of OC San is conducted annually by independent certified public accountants. The Annual Comprehensive Financial Report includes the financial position and activity of the organization and is prepared by the Financial Management Division. Responsibility for both the accuracy of the data, and the completeness and fairness of the presentation, including all disclosures, rests with OC San. The auditor’s report on OC San’s basic financial statements and supplementary information renders an unmodified opinion on OC San’s basic financial statements for the year ended June 30, 2024. OC San has been awarded the Government Finance Officers Association Certificate of Achievement in Financial Reporting for 31 consecutive years. Along with monthly budget reviews and quarterly reporting to the Board, OC San’s internal accounting controls adequately safeguard assets and provides for proper recording of financial transactions. 30 | Strategic Plan — 2025 31 | Strategic Plan — 2025 Budget Control Resources OC San has various structures, procedures, and resources in place to help assist with project and operating budget controls. Several software systems such as PM Web, Request to Purchase, JDE reports, and monthly operating budget reports provide information and have controls in place to be able to restrict purchases to budgeted amounts and monitor overall spending per division. Contract structures have also been optimized to fix costs over longer periods to ensure controlled and predictable expenditures for goods, services, and labor. Future Policy Statement OC San will maintain and enhance the sound fiscal condition of the organization by regularly updating and following the individual policies that provide guidelines for OC San’s day-to-day financial affairs. The scope of these policies includes accounting, purchasing, auditing, financial reporting, internal controls, operating and capital budgeting, pay-as-you-go for capital expenditures, revenue management, cash and investment management, expenditure control, debt management, and planning concepts. OC San will actively monitor budget expenditures, be transparent, submit quarterly financial reports to the Board, have financial information available to the public, and follow industry best practices. OC San’s accounting and financial reporting systems will be maintained in conformance with generally accepted accounting principles and standards promulgated by the Governmental Accounting Standards Board. Initiatives to Support Progress Toward the Policy Goal • Use established resources, along with developing and implementing additional resources to assist OC San staff in tracking and monitoring expenditures to ensure smooth business operations while maintaining budgetary control. • Maintain a fiscally responsible financial plan that is based on long-term planning which supports stable rate setting and a pay-as-you-go philosophy for operating and capital expenditures. • Leverage the centralized training program to provide targeted training opportunities for employees to remain current with financial best practices and OC San fiscal policies and procedures. • Monitor the long-term debt program and continually assess market conditions to identify possible opportunities to reduce outstanding debt balance and term, while maintaining a AAA rating. Maintain reserve levels within policy guidelines, while optimizing the use of available funds to finance capital programs and ensure a balanced budget. Asset Management Policy Summary Policy Statement The Orange County Sanitation District (OC San) will assess and manage the collection and reclamation plant systems and assets to improve resilience and reliability while lowering lifecycle costs. This will be accomplished through adaptive operation, coordinated maintenance and condition assessment, and planned capital investment. OC San will balance maintenance, refurbishment, and replacement strategies to maximize useful life, system availability, and efficiency. Background OC San is a regional governmental agency principally chartered to protect the public health through collection and treatment of wastewater. The governing Board of Directors has defined this role to include the recovery and utilization of resources from wastewater for the public good as a part of that mission. The environmental impact mitigation of the human activity of 2.6 million people and the 479 square miles OC San serves is our principal concern. OC San owns and operates extensive facilities to achieve its mission. OC San estimates the replacement value of the civil, mechanical, and electrical assets in its collection system, Plant No. 1 in Fountain Valley, and Plant No. 2 in Huntington Beach to be $15.7 billion. OC San has been building the piping, pumping, and treatment infrastructure it utilizes for over 70 years. It is necessary to expand, renew, replace, demolish, and rebuild components of the system to deal with wear and tear and meet new challenges. The early years for OC San were characterized mostly by capacity expansion to meet the challenges of increased flows as the county grew. The late 1970s to 2012 were more defined by improved levels of treatment. The last thirteen years have been focused on increasing the level of recycling while rehabilitating and replacing facilities to maintain reliable operations. One of the key success factors for OC San has been the ability to maximize the life of our facilities, through cost-effective maintenance and long-range planning to ensure reliable systems. Current Situation OC San is a highly planned, forward-looking organization. The collection system and each of the reclamation plants are broken down into granular functional parts. Each part is well defined, and future requirements are routinely updated within the annual asset management plan. This plan may also be supplemented with detailed planning studies to optimize the timing and extent of upcoming projects. OC San has a detailed understanding of what is owned, what condition it is in, and how it is capable of performing. The collection system is made up of independent pipe networks that were installed by the former independent sanitation districts to deliver flow to the joint treatment works. The natural watershed drainages in the service area are served by major trunk sewer systems. OC San has worked with member agency staff to understand future development plans, flow estimates, and has collected historical inflow and infiltration rates during wet weather events to assure adequate flow carrying capability exists in each trunk sewer system. 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. Detailed modeling efforts are used to determine when upgrades are required. The reclamation plants are broken down into two process units. Each plant has preliminary treatment to remove debris and grit, primary treatment for gravity settling solids, multiple biological secondary treatment systems, solids handling and dewatering, power generation and 32 | Strategic Plan — 2025 33 | Strategic Plan — 2025 distribution utilities, water and air system utilities, and an outfall system to release treated water to the ocean. Each plant can treat up to 320 million gallons per day of wet weather flow, but only 185 million gallons is the combined average treated by both plants. OC San must always maintain the ability to treat both the average flow and peak wet weather flow. OC San understands that every asset has an expected life. Electrical systems with electronics are generally limited by component obsolescence to 20 years of life and electrical distribution equipment is limited to 30 to 40 years of life. Mechanical and coating systems are also generally limited by erosion, corrosion, and wear to 20 years of life. Civil structures and pipes are generally limited to 60 to 80 years of life if maintained on a regular basis. Generally, process facilities are renewed about every 25 years. OC San creates and adopts an annual Asset Management Plan to renew or replace facilities on this regular basis. Collection system projects are driven by growth projections or condition findings. Pipes are upsized or renewed based on flow projections, corrosion observation, or coating system failure. The 15 regional pump stations are renewed about every 25 years due to the mechanical wear and tear, and electrical component obsolescence needs.The master plan for the reclamation plants is much more dynamic. In addition to the electrical, mechanical, and civil asset considerations, there is also the need to meet new requirements. The new requirements are driven by regulatory requirements or by the Board of Directors to change a discretionary level of service. Examples include capacity demands (more water, more solids), lower discharge requirements (lower Biochemical Oxygen Demand/Total Suspended Solids to the outfall, lower nutrients to the ocean), more water for reclamation, better energy conversion of solids. The annual Asset Management Plan looks at the anticipated needs and levels of service to lay out a detailed project plan to morph OC San infrastructure over time to meet the expectation. Renewal or replacement projects with costs and schedules are laid out for each individual unit of the reclamation plants to address capacity, condition, level of service, and anticipated new regulatory drivers. Future Policy Statement OC San will continue to invest in the infrastructure necessary to meet its mission. OC San will seek to provide its required level of service at the minimum lifecycle cost for its collection and treatment/reclamation systems. The annual Asset Management Plan is the basis of the Capital Improvement Program (CIP) and the means to update and modify the CIP to meet new requirements and conditions as time goes by. OC San will understand in a transparent way what it owns, the condition of those assets, the capacity of collections and treatment required, the level of service required by its regulators and Board of Directors. OC San will work to anticipate new regulations that may require system improvements. This understanding will drive coherent operations, targeted maintenance, and capital investment strategies to assure resilient, lowest lifecycle cost compliance with the requirements. Operations is committed to optimizing the operation of the systems to extend equipment life and minimize energy and chemical utilization, while meeting all regulatory and level-of-service requirements. Maintenance is committed to maintaining the installed assets in a ready state for operations. Maintenance will seek to balance individual component preventive maintenance, repair, and renewal in harmony with the CIP. The CIP is based on the annual Asset Management Plan, and will execute the projects to install, renew, or replace trunk sewers and reclamation plant units on a scheduled basis. Asset Management at OC San is the living management of the operation strategies, maintenance plans, and implementation of the CIP. OC San will find creative ways to maximize asset life and meet capacity or level of service goals through operations and maintenance. OC San will annually reassess its condition, capacity, level of service, and regulatory conditions to drive operations and maintenance practices and modify the CIP. Initiatives to Support Progress Toward the Policy Goal • Continue developing an annual Asset Management Plan documenting the condition of the collection system and reclamation plants, and upcoming maintenance or capital projects. • Coordinate the efforts of operations, collections, mechanical maintenance, electrical maintenance, instrument maintenance and engineering through process area teams to assure OC San’s resources are focused on the high priority work functions. • Identify critical collections and plant assets that have long lead times for parts and replacement and mitigate procurement risks and impacts to collections and plant resiliency based on market conditions. • Maintain a 20-year forecast of all CIP projects needed to maintain or upgrade OC San’s assets on a prioritized risk basis to establish rate structures. • Leverage asset information and tools to define the remaining useful life of assets. 34 | Strategic Plan — 2025 35 | Strategic Plan — 2025 Cybersecurity and Artificial Intelligence Policy Summary Policy Statement The Orange County Sanitation District (OC San) is committed to building and maintaining resilient, secure, and ethically governed technology systems. This includes a robust cybersecurity posture and the responsible adoption of Artificial Intelligence (AI), including both generative AI and advanced operational AI. As OC San advances its digital transformation, the agency must ensure that its technology practices safeguard data, systems, and operations, while also leveraging innovation to improve service delivery, operational efficiency, and decision-making. This policy outlines OC San’s dual approach: securing our digital assets from evolving threats and strategically implementing AI in a phased, ethical, and transparent manner aligned with organizational goals. Background Cybersecurity has become an increasingly complex challenge for all public agencies. Threats from nation-states, cybercriminals, and insider risks continue to grow in scale and sophistication. At the same time, the rapid rise of artificial intelligence—particularly generative AI like ChatGPT and Microsoft Copilot — presents both powerful tools for operational efficiency and significant ethical, legal, and cybersecurity risks. OC San recognizes the need for continuous improvement in both cybersecurity readiness and AI maturity. Cybersecurity must be embedded across all technology layers, and AI must be introduced through a structured governance framework that supports safe and equitable innovation. Current Situation OC San has significantly expanded its cybersecurity capabilities over the past several years. OC San now maintains a 24/7 Security Operations Center (SOC) -as-a-Service, with staffed security and a comprehensive portfolio of protection measures, including: • Security Awareness & Training: Quarterly training, phishing simulations, and targeted sessions for IT and engineering teams. • Vulnerability Management: Continuous scanning and patching supported by threat intelligence from US-CERT, ICS-CERT, and others. • Intrusion Detection & Response: Tools include firewalls, behavior analytics, web gateways, and next-gen anti-malware. • SOC Monitoring: Around-the-clock threat monitoring for network reliability and integrity. • Privileged Access Management: Tools to control and audit administrative access. • Data Backup & Disaster Recovery: A 3-2-1-1-0 strategy with monthly restore testing. • Security Incident Response: Playbooks and partnerships with DHS, FBI, and private incident response firms. • Security Assessments: Regular third-party security reviews and red team exercises. Artificial Intelligence OC San is in the early stages of AI implementation, following a “crawl-walk-run” maturity model to ensure thoughtful and responsible adoption. Current activities include: • AI Use Guidelines: Initial generative AI use policy established and aligned with HR. • AI & Data Analytics User Group: A cross-functional team exploring and piloting use cases. • Pilot Programs: Microsoft Copilot and ChatGPT pilots underway to improve office productivity. • Trends & Education: Ongoing training based on insights from Microsoft, Gartner, and industry groups. AI is being approached in two distinct categories: • Generative AI — Focused on content creation (e.g., text, code) to support administrative and communication functions. • Operational AI — Used for predictive analytics, SCADA optimization, video input, and equipment monitoring. Future Policy Direction Looking ahead, OC San will continue to strengthen and evolve its cybersecurity and artificial intelligence capabilities to meet the demands of a rapidly changing technological landscape. Cybersecurity incidents are no longer a question of “if” but “when,” and OC San is committed to building a resilient security program that anticipates threats and responds effectively. This includes continuous refinement of its threat detection, incident response, and recovery protocols. At the same time, the agency will expand its AI capabilities beyond pilot programs, with a focus on operational applications such as predictive maintenance, real-time process optimization, and intelligent video surveillance. A phased AI maturity model—moving from foundational awareness to full-scale implementation—will guide this progression, ensuring that each stage builds the necessary governance, technical expertise, and ethical safeguards. As both cybersecurity and AI continue to evolve, OC San will align its strategies with emerging best practices and maintain governance frameworks that address key risks such as data privacy, misinformation, algorithmic bias, and system integrity. By integrating security and innovation, OC San aims to responsibly adopt new technologies that enhance service delivery and protect public trust. Initiatives to Support Progress Toward the Policy Goal To support the continued advancement of both cybersecurity and AI, OC San will pursue the following initiatives: Cybersecurity Initiatives • Conduct tabletop exercises to test and improve incident response readiness. • Expand SOC capabilities and automation to support real-time threat protection. • Perform ransomware readiness and third-party red team assessments. AI Initiatives • Implement a phased AI resourcing plan leveraging support from Microsoft and Gartner. • Launch awareness campaigns and targeted training for Microsoft Copilot and other AI tools. • Evaluate AI infrastructure options (e.g., hosted vs. on-premises). • Expand operational AI use in areas such as SCADA, asset health monitoring, and CCTV analytics. • Continuously update generative AI policy to reflect advancements and align with OC San values. 36 | Strategic Plan — 2025 37 | Strategic Plan — 2025 Property Management Policy Summary Policy Statement The Orange County Sanitation District (OC San) owns and operates assets throughout our service area located in property owned in fee, through easements, and in the public right-of-way. OC San will identify and protect all its property rights to assure that our assets are not encumbered or encroached upon so that the facilities may be properly operated, maintained, upgraded, and replaced. Background OC San owns and operates $15.7 billion in assets. A portion of those assets include buildings, easements, rights-of-way, while also managing encroachments. OC San has a real property analyst that serves as a resource in support of OC San’s real property assets. The position acts as project leader and/or technical expert for real property matters, including purchase, sale, lease, rent, acquisition, disposition, appraisal, inspection, title, right of way, easements, permits, licenses, contracts, agreements, relocation, property and space management, and other related activities. Periodically, OC San sells and purchases property to support its efforts. Since these transactions are limited and not core to OC San, it has been determined that it is more cost effective to augment OC San resources with contracted specialized real estate services. Current Situation OC San manages its physical property and property rights in support of Reclamation Plants Nos. 1 and 2, 15 pump stations, and 388 miles of trunk sewer lines in the Collection System. The real property analyst works closely with Operations and Maintenance staff to ensure that OC San has the necessary easements and rights-of-way for operations along with unencumbered access for repairs and maintenance. Staff works with Engineering to obtain property, easements, and rights-of-way to facilitate the completion of projects for our Capital Improvement Program (CIP). Additionally, OC San manages landscaping, building maintenance, and security for its facilities. Future Policy Statement OC San will effectively manage its property assets and actively manage all encroachments, encumbrances, easements, and rights-of-way. When prudent, OC San will augment resources with contracted specialized real estate and property management services. OC San staff will work to support the property needs of Operations and Maintenance and the CIP. Initiatives to Support Progress Toward the Policy Goal • Leverage technology to review property rights and identify encroachments or encumbrances that restrict operation, maintenance, inspection, or emergency repair access to remove encroachments or encumbrances. • Collaborate with Engineering to obtain property, easements, and rights-of-way in a timely manner for capital projects. • Augment OC San resources with contracted specialized real estate services to limit the need for additional staffing. Organizational Advocacy and Outreach Policy Summary Policy Statement The Orange County Sanitation District (OC San) will create and disseminate information to our stakeholders with an end goal to educate, inform, and garner support for the services provided, thus allowing us to operate in a more efficient and effective manner. OC San will deliver messages that are accurate, transparent, and designed to foster public trust and confidence. Additionally, following legislative activity will ensure OC San’s interests are explained and considered. Background OC San provides regional sewer service for 2.6 million people living, working, and commuting in central and northwest Orange County. The various stakeholders include over 650 employees, 50 local elected officials appointed to our Board of Directors, regulators, policy makers, and the public. It is critical for OC San to have a multi-pronged outreach program to reach the intended audiences and to gain support for OC San’s mission. OC San provides services and tools to effectively communicate about the various programs that help achieve its mission. These programs include: • Student Educational Outreach Promoting and educating the youth within our service area on OC San’s mission and the essential services we provide. Reaching out to students allows for future generations to be aware of the environmental impact we each make and what we can accomplish working together. This knowledge will help our future generations to act and make positive changes. It also introduces them to an industry that they may be unaware of as a career choice. We do this through programs such as Inside the Outdoors which goes directly into classrooms to teach the wastewater treatment process; school-based plant tours that give them an inside view into a treatment plant and how the system works; events such as the Children’s Water Festival, which provides an opportunity to reach thousands of local children in a short amount of time with clear and direct messaging; our partnership with local libraries; and scholarship opportunities which is an incentive for students to get involved in developing messages for environmental issues. • Infrastructure Outreach OC San has more than $15.7 billion in infrastructure that must be designed, operated, maintained, replaced, and enhanced to continue providing the essential service of protecting public health and the environment. Forming a positive presence in the community prior to the start of construction projects or maintenance activities is imperative to build trust, understanding, and support for the necessary construction. This is done through an extensive outreach program that develops and implements communication tools to engage the communities affected by OC San construction projects. This includes dedicated community liaisons, construction webpages, collateral material, presentations, etc. Over the next fiscal year, over two dozen projects will be in construction with various degrees of public impacts. • Employee Engagement Open and honest communication with our employees creates a positive and trusting environment which can result in a more engaged workforce and ambassadors for our agency. OC San creates employee engagement by utilizing various communication methods to share agency- 38 | Strategic Plan — 2025 39 | Strategic Plan — 2025 wide messages. A diverse toolkit of communication pieces allows messages to be delivered to over 660 staff with various professional backgrounds, work shifts, work locations, and access to online materials. This toolkit of communication pieces includes The San Box (intranet), Pipeline Newsletter, Three Things to Know email, etc. • Brand Recognition As an industry leader, OC San must ensure its brand and image are portrayed accurately and positively. A cohesive voice, message, look, and feel are critical to maintaining a positive public perception and the trust granted to us by the community we serve and the stakeholders we work with. To build and maintain a positive image, we engage in general outreach efforts such as plant tours; community newsletters; a Speakers Bureau Program (which allows us to go into the community and meet with various groups to inform them of who we are and what we do); Member Agency Outreach Toolkits which allows us to increase our reach to our rate payers via their communication channels; an informative and educational website, an active social media presence; and the development of programs such as Wastewater 101 Citizens Academy which provides an opportunity to showcase OC San’s operations and initiatives for our ratepayers, fellow agencies, and influential public. • Regulatory and Legislative Advocacy OC San also recognizes the need for an active regulatory and legislative advocacy program at the local, state, and federal levels to ensure that the interests of the rate payers and the Board of Directors are communicated, understood, and supported. Towards this end, the legislative and regulatory team actively monitors and engages officials across Orange County, California and in Washington, D.C., and takes appropriate action in support of, or opposition to, legislative and regulatory initiatives. Current Situation OC San is an industry leader involved in innovative and significant programs. However, it is most often seen as a silent utility due to its consistent attainment of its mission. News coverage for a wastewater resource recovery agency is most often about a mission failure. People tend not to think about their wastewater or where it goes until a beach is closed or a spill occurs. In addition, OC San has no direct connection to its ratepayers. User fees are paid via property tax bills thus eliminating an opportunity to reach our customers directly. This ultimately results in a limited understanding of OC San, what we do, and the important service provided to the community. OC San’s outreach efforts are imperative to positively inform and educate the public we serve about the value we provide, including policy makers and regulators. OC San actively works with other public agencies in its service area to develop opportunities to provide additional value from the assets we own and operate to the ratepayers we serve. Initiatives like dry weather urban runoff diversion, and full reclamation of wastewater to potable water are examples of public-to-public partnerships. Future Policy Statement OC San will creatively and effectively develop communication tools and tactics to inform and educate our various stakeholders. As a silent utility, is it imperative that OC San connect with the public we serve in a clear and transparent way to create a bank of trust, and garner support for the programs that allow us to continue protecting the public health and the environment. OC San will maintain an active legislative and regulatory outreach program to help inform and guide leaders to ensure the wastewater industry is able to protect the public health and environment in a cost-effective way. OC San will engage with other local government entities and nonprofit organizations to coordinate our existing messaging and services; and will search for new and innovative ways to add more value from our assets and operations. Initiatives to Support Progress Toward the Policy Goal • Implement a multipronged outreach strategy that will include industry and media coverage for the Supercritical Water Oxidation project and Deep Well Injection. • Develop and implement a Local Government Affairs Outreach Program to enhance OC San business goals and build local relationships that benefit OC San, cities we serve, member agencies, and officials. • Actively monitor and engage in regulatory and legislative activity across California and Washington, D.C., and take appropriate action in support of, or opposition to, legislative and regulatory initiatives affecting OC San and the wastewater industry. This includes using Monitoring and Analysis, Advocacy Days, Position letters and Funding Requests (as deemed suitable). 40 | Strategic Plan — 2025 41 | Strategic Plan — 2025 Environmental Principles 42 | Strategic Plan — 2025 43 | Strategic Plan — 2025 Energy Independence Policy Summary Policy Statement The Orange County Sanitation District (OC San) will strive to be energy neutral. Electrical, thermal, and methane gas generation will be maximized within the current anaerobic digestion engine generator infrastructure. Energy utilization will be minimized using sound engineering and financial principles. OC San will investigate new technologies to more directly convert solids associated with wastewater treatment into energy. Background OC San is an environmental steward that seeks to maximize the harvesting of energy available in the incoming wastewater. A natural result of wastewater treatment is the separation and concentration of solid and gaseous materials which provide opportunities to create sustainable and renewable energy and reduce greenhouse gas emissions. OC San is also committed to be a good neighbor. As such, significant amounts of energy are spent capturing and converting odorous air and vapor streams. OC San has pursued a comprehensive program to cover and seal its liquid and solid processes. Air streams are ducted to large fans which move thousands of cubic feet of foul air per minute through chemical, biological, and activated carbon beds to scrub the air of odorants that are regulated or may be perceived as a nuisance by the community. OC San has utilized an anaerobic digestion process that relies on biological conversion of solid organic material to methane and carbon dioxide gas or biogas. The biogas is converted to electrical and heat energy in our central generation facilities for internal use. Current Situation OC San invests prudently in lifecycle energy efficiency to minimize the use of energy to achieve its mission. Process technology selection includes life-cycle cost analysis. Treatment processes and pump stations are designed with energy efficient equipment Aeration blowers and diffusers are selected by overall efficiency. Lighting systems are upgraded over time to more efficient technologies and lighting levels are balanced between safety and security needs versus energy utilization and light pollution concerns. Facility designers and operators make careful choices regarding the utilization of every watt of electricity, BTU of heat, and therm of gas consumed. OC San seeks to maximize the internal production of energy. The primary source of energy is biogas. Organic solids collected and concentrated in the water treatment processes are converted biologically to biogas composed of 65 percent methane, 34 percent carbon dioxide, and other trace constituents. OC San has been using this technology since the 1950s. The production of digester gas has been maximized by improved mixing, heating, sludge feeding, chemical addition to limit trace pollutant production, and the receiving of fats, oils, and grease. OC San is currently working with Orange County Waste and Recycling to receive preprocessed food waste up to available digestion, gas handling and generator capacity. A food waste receiving station is designed and waiting to be bid once a food waste supply contract is signed. The biogas from the digesters is cleaned and converted into electricity, heat, and exhaust gas. Plant No. 1 has three 2.5 megawatt (MW), 12.47kV central generators. Plant No. 2 has five 3MW, 12.47 kV central generators and a 1MW steam turbine. These internal systems of energy harvesting provide roughly 66 percent of OC San’s electrical demand and 92 percent of OC San’s thermal demand in the treatment plants. Heat from the central generation at Plant No. 1 is used to heat the digesters and heat and cool select buildings. Heat from the central generation at Plant No. 2 is used to heat digesters. The central generation exhaust gas is regulated tightly for nitrogen compounds, carbon monoxide, particulates, and volatile organic compounds which require air emission controls to meet permit limits. OC San can shift the digester gas between treatment plants via an interplant pipeline and has roughly 11 MW of additional generation capacity if more gas is produced. The additional capacity provides standby to the large outfall pumping system during an electric utility power outage using natural gas. In addition, OC San has a 5 MW, 32 megawatt-hour (MWh) electrical battery storage system at Plant No. 1. The operation of this system is scheduled by Southern California Edison to offset plant loads and reduce the demand on the electric utility grid during peak demand times. The battery storage system is operating under a 10-year contract. OC San will evaluate the renewal of this contract as it reaches the expiration date in December 2029 based on need and available load at Plant No. 1. OC San received approval to participate in Southern California Edison’s Direct Access Program at the end of 2021. In early 2022, OC San enrolled in direct access and was on the spot market, time-of-use rate until May 2022, when a 5-year, flat-rate contract was entered into with an energy provider for consistent and cost-effective energy costs. The Plant No. 1 electricity imports vary between 1 MW and 6 MW, based on the time of day and if the battery storage system is charging or discharging. Currently, the Plant No. 2 load is close to zero on average. The Headquarters Building is fed from Plant No. 1 and has solar photovoltaic cells in the parking lot and at the top of the building to offset building energy requirements. The 2024 Energy and Digester Gas Master Plan evaluated the use of solar photovoltaic cells with and without batteries at Plant No. 1 and solar photovoltaic cells only at Plant No. 2. OC San’s low energy rates resulted in a long payback period for solar. The flat energy rate with direct access provided little benefit for battery storage except reducing some peak demand. This study also evaluated converting a portion or all of the biogas to renewable natural gas for export to the gas pipeline. These alternatives were determined not to be cost effective. The selling of biogas would require additional natural gas or electricity to offset the loss of electricity generated using biogas. In an era where environmental concerns are at the forefront of global discussions, finding sustainable solutions for creating energy from the solids derived from wastewater treatment is more critical than ever. OC San is researching a potential alternative to anaerobic digestion and agricultural reuse of our solids materials. Supercritical Water Oxidation (SCWO) offers a potential alternative to anaerobic digestions, internal combustion engines and biosolids production. OC San is currently conducting a SCWO research project which offers the opportunity to directly convert wastewater solids materials to high temperature inert materials. OC San partnered with 374Water to build a six-ton-per-day demonstration project called AirSCWO Nix6. This process uses air and water at a high temperature and pressure to oxidize complex compound materials into more basic and benign compounds. This process should be operational in late 2025 or 2026. SCWO provides opportunities to solve future stringent air emission requirements, treatment of emerging contaminants such as Per- and polyfluoroalkyl substances compounds, treatment of microplastics, increased food waste utilization, and enhance solids recovery. Once the 6-ton SCWO unit is operational, OC San will explore the option of purchasing and testing a 30-ton SCWO unit. The solids screening portion of the SCWO system has already been sized for 30 tons. These larger units are anticipated to incorporate the ability to generate clean electricity through steam generation or other means. 44 | Strategic Plan — 2025 45 | Strategic Plan — 2025 Future Policy Statement OC San seeks to be energy independent by self-generating all the electrical and thermal energy necessary to sustain its operations. This will be accomplished by economically minimizing its utilization requirements and maximizing energy harvested from the wastewater it receives. Energy independence will reduce OC San’s environmental impact and improve its operational reliability and resiliency. Any new occupied buildings will include solar in accordance with building code requirements. Staff recommends that research continue to maximize energy harvesting and to minimize energy usage to make OC San energy independent in the mission of protecting the public health and the environment. Supercritical Water Oxidation and other biosolids thermal conversion technologies offer some exciting opportunities to cut power use, reduce diesel fueled transportation, and create useful energy. Initiatives to Support Progress Toward the Policy Goal • Maximize the anaerobic digestion conversion of organics to methane through receipt of food waste and operational techniques. • Continue to support the conversion of biomethane into electricity and heat for process use. Improve systems as necessary to comply with air regulations. • Pursue technology innovation to reduce energy use, reduce transportation energy impacts, and reduce greenhouse gas impacts. Climate Adaptation and Catastrophic Event Resilience Policy Summary Policy Statement The Orange County Sanitation District (OC San) aims to design, maintain, and operate valuable wastewater assets that withstand or adapt to adverse conditions in a reasonable manner that is both cost-effective and sustainable for present and future generations. These adverse conditions include drought, heavy rains, flooding, sea level rise, earthquakes, tsunamis, extreme heat, wildfires, high wind, and electrical grid interruptions. OC San is also committed to economically minimizing its greenhouse gas emissions to minimize its impact. Background OC San owns and operates extensive wastewater collection and treatment facilities valued at $15.7 billion. OC San’s service area faces special challenges because of the geographic location of its facilities. These challenges include: its position on and near seismic risk factors, its proximity to the Pacific Coast, adjacency of its treatment facilities to the Santa Ana River, and being served by increasingly fragile energy utilities. OC San’s facilities are situated on or near several seismic risk factors. Plant No. 2 is located directly on top of the Newport-Inglewood fault zone. Both plants and the collection system are influenced by many adjacent major and minor faults capable of delivering damaging energy. Both of our reclamation plants and most of our collection system sit on top of silty, alluvial soils that can have the effect of amplifying the ground motion and increasing the risk of liquefaction during a seismic event. The proximity of the treatment facilities to the Santa Ana River adds the risk of lateral spread at both sites. OC San has invested significantly over the last 50 years to improve the soils, foundations, and structures to mitigate these seismic risks. As geotechnical and structural knowledge and building codes progress, improvements and facility replacements will be necessary. Another seismic risk associated with having a reclamation plant and several pump stations located on the Pacific Coast is the risk of tsunami inundation. OC San has been working with and reviewing plans with the City of Huntington Beach and the City of Newport Beach to understand and quantify the risks. In addition, OC San actively monitors and reviews code updates, such as the recently released American Society of Civil Engineers (ASCE) 7-22 standard by the American Society of Civil Engineers, which outlines design parameters for critical assets located in tsunami-prone regions. This information sets the elevation for critical assets. OC San understands that climatic factors we face change widely over time. OC San’s systems must perform in extreme wet weather situations (atmospheric rivers), extreme dry weather conditions (drought), extreme tidal conditions (king tides, rising sea levels), and high and low temperature extremes. OC San generally designs for historical and expected “average conditions” for optimal performance but must also assure operations for extreme weather events. OC San serves a critical public health role. The operations must be reliable 24 hours per day, 365 days a year. Electricity, and to a lesser extent natural gas, are necessary for pumping and treatment operations. Both electricity and natural gas supplies have become increasingly vulnerable to interruption. Electricity supplies are more vulnerable due to utility Public Safety Power Shutdowns during severe weather conditions, loss of local power generation assets, aging infrastructure, extreme weather events, and high winds. Natural gas supplies are more vulnerable due to the loss of local storage capacity, aging infrastructure, line corrosion, and more stringent regulatory requirements. OC San has significant capacity to self-supply critical energy requirement for extended periods. 46 | Strategic Plan — 2025 47 | Strategic Plan — 2025 Current Situation OC San has spent considerable effort quantifying its seismic, climate, and utility supply risks. Several key studies were completed over the past several years. The most acute risk factor faced by OC San is seismic risk. Climate and utility supply risks are more accurately described as chronic risks. Seismic risk factors include ground shaking, liquefaction, lateral spreading, and fault rupture. Both reclamation plants are situated in a historic riverbed with poor soil conditions. The collection system is vulnerable to failures during seismic events. Building code developments to seismic design has changed greatly over OC San’s history and will continue to advance in the future. Many of our critical structures were designed or installed prior to the advancements that occurred due to the major earthquakes of the 1990s. Significant effort has been expended to better characterize the soil conditions under our reclamation plants and pump stations. Projects to replace existing unit processes will be scoped and budgeted to provide seismic resilience. These measures include deep soil mixing to strengthen ground stability, various foundation designs and building structure improvements. For refurbished facilities, the cost to provide soil improvements for existing structures to mitigate liquefaction will be evaluated based on the importance of the structure and the associated impact on pumping and treatment plant operations during dry weather conditions. Tsunami resilience and flooding protection can go hand in hand. Tsunami protection requires a more robust wall footing and wall structure. To a great extent, these two risk factors can be mitigated in the same way. The structural design guidelines for structures in tsunami-prone areas, as outlined in ASCE 7-22, represent a well-established and peer-reviewed industry standard. By complying with this standard for Huntington Beach and Newport Beach, OC San will be reasonably prepared for flooding caused by extreme storm events and conservative sea level rise projections at Plant No. 2 and pump stations in the City of Newport Beach. A tsunami-resistant wall has been designed for a large portion of the southern perimeter of Plant No. 2 and is currently under construction. A future project will construct the remaining portion of the tsunami-resistant wall. Additionally, OC San routinely updates its design guidelines based on the latest California Climate Assessment reports, Federal Emergency Management Agency flood maps, and ASCE standards for flood-resistant design and construction (such as ASCE 24), ensuring alignment with evolving climate science and regulatory expectations. OC San has also expended significant effort to prepare for the effects of weather extremes on its operations. Inflow and infiltration throughout the sewer system during intense storm activity have multiplied average dry weather flow rate by up to three times in past years. During recent storms, peak wet weather flows have exhibited fewer extreme peaks due to inflow and infiltration improvements throughout the collections system. Sewer rehabilitation projects helped reduce the amount of inflow and infiltration by lining the pipe or grouting the pipe joints. OC San has significant wet weather capacity and will continue to maintain a 640 million gallon per day influent and outfall capacity which is roughly 3.5 times our average dry weather flow. Historically, high rains as seen in 1863, 1938, 1983, 2005, 2017, and 2023 will push our systems to the limit. We have recently experienced king tides higher than previously anticipated which is impacting our coastal pump stations. OC San can also shift significant influent flow from Plant No. 1 to Plant No. 2 through the interplant line and a portion of the flow from Plant No. 2 to Plant No. 1, which creates additional resilience for risk factors. On the topic of utility supply, OC San built redundant supplies for its most critical needs: electricity, natural gas, and water. OC San has maintained three sources of electricity supply for approximately 30 years. The reclamation plants can be supplied with power from Southern California Edison, OC San’s Central Generation Plants, or onsite diesel generation systems to maintain basic operation to protect public health. In terms of natural gas, OC San has been producing bio-methane through anaerobic digestion since the 1950s with enough capacity to provide electricity for half of the loads at Plant No. 1, all the loads at Plant No. 2, heating and cooling loads at Plant No. 1, and heating loads at Plant No. 2. The 2024 Energy and Digester Gas Master Plan evaluated the standby power capacity at Plant Nos. 1 and 2 and determined that all critical loads required to meet the permit requirements could be operated using the Central Generation Plants and standby generators with a temporary reduction in secondary treatment aeration blower capacity during a 48-hour outage period. Select pump stations are provided with standby generators and 24 hours of fuel for pump stations that require response in two hours or less during a power supply failure. Portable generator connections have been installed at the pump stations to provide increased reliability and maintain pump station operation in the event the onsite standby generators fail or there is an electrical fault. As environmental stewards, OC San also realizes that it is an emitter of greenhouse gases. OC San has been working for many years to minimize its greenhouse gas footprint through several means such as energy efficiency, methane gas capture and use, engine emission control systems, and organic waste conversion systems. OC San is working toward an innovative approach that has the potential to create a negative carbon footprint for the agency. The proposed Biosolids Deep Well Injection (BDWI) project presents an innovative approach to managing biosolids. It will screen and pump biosolids several thousand feet underground into a sand layer below several layers of rock. At this depth, the biosolids are separate and safely segregated from the drinking water aquifer. If fully implemented, this solution has the opportunity to reduce semi-trucking milage by 4.5 million miles per year along with its costs and associated greenhouse gas creation, thus creating carbon sequestration by locking away carbon rich biosolids, Per- and Polyfluoroalkyl Substances (PFAS) and microplastics received in wastewater tend to concentrate in biosolid, so they would also be safely sequestered with the biosolids. OC San has completed a Deep Well Injection Feasibility Study for Plant Nos. 1 and 2. It is anticipated that a project will be implemented which will construct a DWI Facility at Plant No. 1. This facility will include a receiving station to receive trucked biosolids from Plant No. 2. This project will include permitting and will be designed and constructed using a progress design-build contract. Future Policy Statement OC San will continue to build and improve its facilities to meet the seismic, climate, and energy infrastructure risks that it faces with a long-term, planned approach. Acute life-safety risks that are identified or facilities that are damaged or fail in a catastrophic event will be addressed very quickly. However, it is not practical to update $15.7 billion in facilities every time a code is updated, or a new climate change assessment report is released. OC San will stay abreast of code and climate change projections as they occur and will implement improvements or replacements to facilities on a long-term basis in line with its asset management practices. OC San generally plans to refurbish or replace its mechanical and electrical assets every 20 to 25 years with an average capital improvement investment of $350 million per year over the next 10 years. OC San facilities are designed to meet building codes that are standard to our industry. As time goes on and codes are updated, it is not required to upgrade existing facilities to meet those 48 | Strategic Plan — 2025 49 | Strategic Plan — 2025 latest codes unless mandated by regulation or if an unacceptable risk is identified by not doing so. OC San will accept some incremental risk in having some facilities that are not necessarily compliant with latest building codes until a project to rehabilitate or replace these facilities is developed. All of OC San’s facilities have a planned life span with two to three refurbishment cycles. Identified seismic or flooding vulnerabilities may drive a replacement versus refurbishment decision in the normal capital planning process. OC San will continue to aspire for energy independence which will help mitigate vulnerabilities to loss of electrical and gas utilities. In addition, OC San will continue to maintain third level, diesel generator, electrical supply capability for critical loads at the plants with up to 48 hours of fuel. Pump stations diesel generation will be site specific in its design based on flow risks, hydraulic storage capacity, and site constraints. Either onsite generation or quickly deployable mobile generators will provide standby power. Initiatives to Support Progress Toward the Policy Goal: • Evaluate the seismic vulnerabilities of Plant No. 2 flow processes (primary clarifiers, activated sludge facility, and ocean outfall piping) within the plant. Determine the required improvements to maintain dry weather flow capacity after a seismic event. Incorporate necessary upgrades into future capital improvement projects. • Complete the biannual high flow exercise to assure readiness for a high flow event. Maintain a higher level of readiness October 15 through March 15 and in advance of predicted significant rain events. • Pursue Deep Well Injection of Biosolids to safely sequester carbon rich materials and associated constituent of emerging concern to create a negative carbon footprint for OC San. Food Waste Treatment Policy Summary Policy Statement The State of California limits the volume of organic waste that is diverted to landfills. The Orange County Sanitation District (OC San) will collaborate with the County of Orange, other local agencies, and waste haulers to find ways to beneficially reuse food waste, a type of organic waste to assist cities in our service area in meeting their diversion requirements while increasing OC San’s energy production. Background Whether supplying secondary treated wastewater for the Groundwater Replenishment System, creating renewable energy in the form of biogas from anaerobic digestion to produce electricity, or benefiting from the use of biosolids as a soil amendment, OC San is a resource recovery agency committed to providing resilient and reliable wastewater treatment service while protecting the public health and the environment. In recent years, there has been a significant change in the regulatory landscape regarding the management of organics in California. This encompasses a range of materials including food, green waste, wood, paper, biosolids, digestate, and sludges, all of which are typically disposed of in the landfills. In response to the phaseout of organics as alternative daily cover on landfills a potential market for food waste co-digestion has emerged for the wastewater industry. Co-digestion is the mixing of sewage solids and food waste in an anaerobic digester to create biogas. There is an opportunity for OC San to produce additional biogas, reducing the reliance to purchase electricity from local utilities. Anaerobic digestion is currently at the nexus of important mandates within California, namely: (1) organics diversion from landfills (AB 1826 and SB 1383), and (2) increased renewable energy and fuels generation (SB 32 and SB 100). The primary alternatives for organics management are anaerobic digestion and composting–of which anaerobic digestion is the only process offering energy recovery potential. California cities and counties, along with municipal solid waste haulers, material recovery facilities, and landfills will need to develop collection, processing, and energy recovery infrastructure to actively address these mandates. OC San and other wastewater digester owners are uniquely positioned to assess whether existing and planned digester capacity could be made available to support diverting food waste from landfills. In 2017, OC San completed a comprehensive Biosolids Master Plan (Plan) that provides a roadmap and framework for sustainable and cost-effective biosolids management options and future capital facilities improvement over a 20-year planning horizon. Considering the timeliness of the regulatory mandates requiring organic diversion from landfills and increased renewable energy, the Plan evaluated the feasibility of implementing a high strength organic waste receiving program involving the co-digestion of preprocessed food waste. While food waste digestion appears to be feasible, OC San’s existing infrastructure is not well suited or permitted for receiving, handling, or digesting green waste. Current digester feed, mixing, heating, dewatering and truck loading facilities aren’t designed to deal with cellulosic products in green waste. The highly fibrous material does not readily break down and clogs the various systems optimized for sewage sludge treatment. In addition, there are legal hurdles specified in the California Health and Safety Code, Section 4700, that must be addressed before OC San could operate a solid waste refuse transfer facility. 50 | Strategic Plan — 2025 51 | Strategic Plan — 2025 Current Situation Project Viability OC San’s Plan concluded that the costs to construct and operate a food waste receiving facility could be offset by tipping fees charged to food waste processors/haulers and by additional power generated from the increased digester gas production. The Plan recommended that OC San build an interim food waste receiving station immediately to take advantage of existing digestion and power generation capacity of approximately 150-250 wet tons per day at Plant No. 2. OC San will construct a more permanent facility in the future to utilize OC San’s available capacity. Based on these recommendations, in 2018, OC San’s Board approved a project (P2-124) to construct an interim (10 to 15-year service life) food waste facility to receive, store, and feed preprocessed food waste slurry to the digester complex at Plant No. 2 to generate additional digester gas. The facility will be designed to accept approximately 150 wet tons per day of preprocessed food waste and will produce approximately 15 percent more methane gas for on-site energy production, resulting in a greenhouse gas reduction of approximately 10,800 metric tons of carbon dioxide which is equivalent to the annual greenhouse gases generated by approximately 2,000 passenger vehicles. This is consistent with OC San’s Energy Independence Policy which is to strive to be energy independent by minimizing energy utilization and maximizing useful energy recovery from the wastewater it receives. The final biosolids product currently produced by OC San is anticipated to be largely unaffected by the addition of food waste slurry. Pilot testing conducted by OC San indicates that there will be increased gas production due to mixing sewage sludge and food waste feed stock, but the final biosolids product will remain largely unchanged. A draft Preliminary Design Report was issued in June 2019 for the interim receiving facility which included a viability evaluation concluding that the project is economically justifiable based on project costs and anticipated tipping fees. Final design of the interim food waste receiving station is complete and ready to bid for construction. The 2019-2020 tipping fee was established by the Board of Directors, and the food waste slurry specifications were developed by OC San staff. Between 2020 and early 2023, OC San hosted quarterly check-in meeting with several large municipal solid waste haulers to discuss procuring pre-processed food waste slurry. Although most haulers expressed interest in working with OC San, none were willing to meet OC San’s food waste slurry specifications. In spring 2023, OC San initiated a series of meetings with Orange County wastewater digester owners and Orange County Waste and Recycling (OCWR) to discuss partnership opportunities for in-county food waste preprocessing, co-digestion, composting, biosolids management, and biogas production. The meetings were highly productive, and as of May 2025, the parties have signed a non-binding agreement to assess the feasibility of constructing a centralized food waste pre-processing facility at an OCWR landfill to provide high-quality food waste slurry for co-digestion at in-county wastewater treatment plants. Future Policy Statement Food Waste Slurry OC San will only accept a preprocessed food waste slurry. We do not have land or air permits to handle, sort, and process solid or green waste. OC San will work with other regional partners to develop a county-wide standard for food waste slurry that specifies water, organic, metal, plastic, and glass content requirements. A common specification for slurry will help all parties make investment decisions. Food Waste Volume OC San plans to construct a permanent food waste facility based on the lessons learned from the interim system and the anticipated availability of food waste feedstock. The permanent facility will be able to accept up to 300 wet tons per day and utilize the total available capacity of the existing digesters and gas compressors. OC San also has at least 6 Megawatts of installed electrical generation capacity that can convert the produced digester gas to electricity and heat. OC San believes that the full implementation of the current regulations will create a food waste slurry market significantly greater than 500 wet tons per day in Southern California. Tipping Fee Basis The acceptance of food waste could more fully utilize the system capacity that already exists for the benefit of OC San’s ratepayers. When requested by OCWR, OC San staff will develop an updated base tipping fee rate schedule for Board of Directors’ approval that meets the following criteria: • Recover all capital costs to construct facilities within ten years (this will allow OC San and waste haulers to properly invest in processing facilities). • Recover all on-going costs including operating cost, maintenance cost, electricity usage, biosolids dewatering, and reuse costs. • Food waste will not be operated “for profit” but rather a cost recovered service with tipping fees offsetting costs to not impact OC San’s wastewater service fee structure. Food waste generated and processed within the service area will be charged the base rate and will be prioritized over food waste from outside the service area. This is justified by the fact that the underlying infrastructure of OC San is already owned by service area ratepayers. OC San contracts with service area waste haulers must provide for a pass-through savings to OC San ratepayers. That means waste haulers may charge for collection and processing of food waste but must disclose OC San’s tipping fees and negotiate pricing adjustments as necessary with City or Special District franchise partners. If additional capacity exists, but isn’t utilized by in-service area users, then that capacity may be contracted by out-of-service area users at a premium to help offset the cost of the underlying infrastructure necessary to process the food waste. OC San will pursue grant opportunities to the extent possible to reduce the overall capital and operating cost basis for the program to reduce the tipping fee base rate. Initiatives to Support Progress Toward the Policy Goal: • OC San will accept a preprocessed food waste slurry that meets OC San’s specifications from an in-county partner that is compatible with its existing anaerobic digesters. OC San will charge a tipping fee to offset its costs for capital construction, operations, handling, maintenance, and biosolids disposal. • Design, build, and operate a food waste receiving station. Utilize a county-wide specification for food waste slurry and contract with OCWR to receive and co-digest food waste slurry. 52 | Strategic Plan — 2025 53 | Strategic Plan — 2025 Environmental Water Quality, Stormwater Management, and Urban Runoff Policy Summary Policy Statement The Orange County Sanitation District (OC San) will collaborate with regional stakeholders to accept up to ten (10) million gallons per day of dry weather urban runoff at no cost to the dischargers through its permit-based Dry Weather Urban Runoff Diversion Program (DWURD Program). The primary objective of the DWURD Program is to improve water quality in streams, rivers, and beaches in OC San’s service area without adversely impacting OC San’s occupational safety, collection and treatment systems, reuse initiatives, or permit compliance. Unauthorized discharge of urban runoff to OC San is strictly prohibited. Background OC San is a regional governmental agency principally chartered to protect public health and the environment through an extensive regional sanitary sewer system and a highly effective wastewater treatment operation. The governing Board of Directors (Board) has refined this role to include the recovery and utilization of resources from wastewater for the public good. In addition to beneficial reuse of biosolids and responsible ocean discharge, OC San delivers high-quality treated wastewater to Orange County Water District’s (OCWD) Groundwater Replenishment System (GWRS) for advance treatment and purification followed by storage in the Orange County groundwater basin. OC San operates its regional wastewater collection system in accordance with its Sewer System Management Plan, which was developed in compliance with the California Statewide General Waste Discharge Requirements for Sanitary Sewer Systems, Water Quality Order No. WQ 2022-0103-DWQ. The Board periodically updates OC San’s Wastewater Discharge Regulations Ordinance (Ordinance) to set uniform requirements for all users of OC San’s system and enables OC San to comply with all applicable state and federal regulations. The Ordinance establishes limits on all wastewater discharges which may adversely affect OC San’s system and includes language that prohibits sewer users from discharging groundwater, stormwater, surface runoff, or subsurface drainage to the sewer without written authorization or a valid permit. Uncontrolled discharge of any type is strictly prohibited and any person who violates any provision of the Ordinance is subject to administrative, civil, and criminal penalties. Most of the local sanitary sewer systems within OC San’s highly urbanized service area are owned and operated by cities, water districts, or sanitary districts. These local systems are designed to transport wastewater from homes and businesses to OC San’s regional sewers. These local and regional wastewater systems are designed to be wholly separate from Orange County’s Municipal Separate Stormwater Sewer System (MS4), which is a system of conveyances that includes roads, streets, catch basins, curbs, gutters, ditches, man-made channels, or storm drains that carry surface runoff into receiving waters and is regulated by the Santa Ana Regional Water Quality Control Board. Throughout the year, dry and wet weather urban runoff are collected through the MS4 and discharged along the coastline. During wet weather, the vast majority of urban runoff is comprised of stormwater from rainfall that either travels at a flow rate that does not allow enough time to soak into the ground or whose volume has exceeded the ability of the soil to hold any more moisture. In communities with a high percentage of covered or impervious surfaces, the runoff volume and velocity can be considerably greater when compared to rural areas. Additionally, sheets of runoff in these communities can pick up pollutants and debris from transportation, construction, industrial, and residential sources as they travel by gravity toward storm drains or other low points. Stormwater runoff carries trash, debris, bacteria, chemicals, oil, silt, sediments, microplastics, and other common and emerging contaminants, and is the responsibility of MS4 permittees, who typically have jurisdiction over land use practices and flood control. During wet weather, the volume of surface runoff is well beyond the capacity of OC San’s conveyance and treatment systems. Inflow and infiltration into the sanitary sewer system during storm events can strain the hydraulic capacity of OC San to its limit of under 1,000 cubic feet per second. In addition, storm flow runoff also contains a much greater debris load that would compromise the sanitary sewer system. During dry weather, OC San has the capacity normally reserved for inflow and infiltration to accept urban runoff. The Best Management Practices (BMPs) required of MS4 permit holders such as screening, street sweeping, spill prevention, and waste reduction campaigns help to effectively remove trash, silt, and other debris which help make these relatively small flows more compatible with the sanitary sewer. However, pollutants and pathogens that are not removed by the BMPs are carried by runoff from sources such as excess outdoor irrigation into storm drains which is discharged along the coastline. In response to the significant and persistent adverse impacts from urban runoff to coastal beaches and waters, OC San sought support from the California legislature to accept controlled discharge of surface urban runoff into its wastewater system and was authorized in April 2000 to initiate a permit-based DWURD Program to accept up to three (3) million gallons of dry weather flow per day. OC San Board Resolution No. 00-04 allowed local agencies to apply for a DWUR Permit where there was not an economically or practically feasible alternative and permittees are subject to requirements of the Ordinance. Since its inception, the DWURD Program has significantly improved beach water quality throughout OC San’s service area as evidenced by excellent ratings in Heal the Bay’s Annual Beach Report Cards and a notable decrease in water quality-based beach closures. In June 2013, OC San modified the Dry Weather Urban Runoff Policy (Resolution No. 13-09) to cap discharges received to ten (10) million gallons per day (MGD) and waived fees associated with the program until discharges exceeded 10 MGD, or until the policy is revised. The Board established an action threshold of 9 MGD to trigger revisiting the policy. In addition to DWURD Permits, OC San’s Ordinance allows for normally prohibited wastes such as groundwater, stormwater, surface runoff, and subsurface drainage to be discharged to OC San through a Special Purpose Discharge Permit (SPDP) or written authorization from OC San when no alternate method of disposal is reasonably available to mitigate an environmental risk or health hazard. Both DWURD and Special Purpose Discharge permits carry strict wet weather shut-off and debris limiting provisions to protect the sanitary sewer system from hydraulic overload and the associated sewer spills. These permits also require flow monitoring and constituent sampling so that OC San can assure that water reused, water discharged to the ocean, and biosolids reused for agriculture are safe and fit for their greater environmental and resource recovery programs. Current Situation OC San is currently administering 18 DWURD Permits for diversions that are owned and operated by the City of Huntington Beach, the City of Newport Beach, OC Public Works, Irvine Ranch Water District, and an LLC responsible for the areas in and around Pelican Point community. In addition, 54 | Strategic Plan — 2025 55 | Strategic Plan — 2025 three permit renewals are pending. Since the program’s inception in 2000, the Dry Weather Urban Runoff Program has treated over 10 billion gallons of urban runoff. As of May 2025, OC San received on average, less than 4.5 MGD combined from these facilities, which is well below the current 10 MGD policy cap and 9 MGD action threshold. Under special circumstances, OC San may also accept runoff on a limited-term and limited- volume basis through the SPDP or direct authorization process if there is adequate capacity, the runoff/wastewater meets applicable effluent discharge standards, there is no practical alternative method of disposal, and the runoff/wastewater is captured and held until it can be safely discharged to OC San. In combination, these practices have enabled responsible management of persistent urban runoff challenges in OC San’s service area and support a thriving and healthy local economy. Key Issues for the Future Since the inception of OC San’s DWURD Program, the program success has depended on collaboration among stakeholders to improve beach water quality and urban runoff diversion water quality, coordinate flow management, and minimize any potential adverse impact on OC San’s ocean discharge, biosolids management, and potable reuse. OC San’s enhanced source control program and vigilant operations provide a solid foundation for GWRS water’s safety and reliability. Much of the current urban runoff diversion is attributable to Plant No. 2 in Huntington Beach which now provides source water for OCWD. OC San is keenly aware of the critical role of source water quality and the need for a region-wide commitment to prevent Constituents of Emerging Concern from entering OC San’s system. Although OC San will continue to accept controlled discharge from DWURDs in accordance with Resolution No. 13-09, which supports long-term integrated regional water management, OC San recognizes that urban runoff is a well-established carrier for surface contaminants. The best available scientific studies continue to highlight the need for enhanced surveillance and best management practice for pollution control prior to discharge to OC San consistent with MS4 permit requirements of diversion owners. For example, a 2020 study by the San Francisco Estuary Institute showed that runoff into San Francisco contained over 300 times the amount of microplastics when compared with treated wastewater. A 2021 study that was co-authored by the Southern California Coastal Research Project showed that tire debris in urban runoff released a rubber preservative (6-PPD) that is highly toxic to aquatic life in the Pacific Northwest. As residents within OC San’s service area continue to reduce their indoor water use, there is increasing interest in utilizing dry weather urban runoff as a new source of water for the GWRS. Coupled with the completion of GWRS Final Expansion, the need to reassess available sewer capacity for accepting dry urban runoff was recognized by OC San. A feasibility study was initiated in 2023 by OC San in collaboration with OCWD and Orange County Public Works to identify opportunities to optimize dry weather urban runoff to sewer to augment local water supply. The study determined that there are seven locations with a potential total flow of 2.7 million gallons per day (MGD). These projects will be initiated and executed by sponsoring agencies. Initiatives to Support Progress Toward the Policy Goal: • Issue dry weather urban runoff connection permits to accept up to a total of ten million gallons per day of controlled discharge of dry weather urban runoff where existing conveyance capacity exists, and the constituents within the flow will not adversely impact OC San. • Safeguard OC San’s sanitary sewer system against uncontrolled and unregulated discharge by supporting responsible industry practices for flow management and urban runoff pollutant reduction at the source. Utilize OC San’s pretreatment expertise to support effective urban runoff best management practices and special purpose discharge requests among OC San’s regional stakeholders. • Support responsible and practicable urban runoff management and reuse legislation and regulations. • Initiate timely enforcement actions to safeguard OC San occupational safety, collection and treatment systems, reuse initiatives, or permit compliance. 56 | Strategic Plan — 2025 57 | Strategic Plan — 2025 Potable Water Salinity Control Policy Summary Policy Statement The Orange County Sanitation District (OC San) will partner with other Public Agencies in our watershed to reduce the salinity of the potable water supply of our stakeholders. OC San will use its existing facilities, including its Ocean Outfall, to safely dispose of naturally occurring dissolved solids, or salts, which may be attributed to water reuse, imported water, brackish groundwater, or past agricultural activities. Background: OC San provides regional sewer service for 2.6 million people living, working, and commuting in central and northwest Orange County. The stakeholders include OC San’s ratepayers, the Orange County Water District (OCWD), the Santa Ana Watershed Project Authority (SAWPA), potable and reclaimed water providers in OC San’s service area and upstream of OC San in the Santa Ana River watershed, and State and Federal regulatory agencies charged with protecting water quality and the environment of the Santa Ana River basin. The groundwater basin of central and northwest Orange County is managed by OCWD and supplies the majority of potable water to local water suppliers. The groundwater basin is naturally recharged by flows from the Santa Ana River, local rain infiltration, the Groundwater Replenishment System, and purchased imported water from Metropolitan Water District. Flows from the Santa Ana River and imported water have the potential to have high dissolved solids or salinity. OC San has been working cooperatively with SAWPA and its predecessor agencies since 1969 to intercept high salinity, low quality water that would otherwise flow to the Santa Ana River. The initial problem was attributed to the high concentration of dairy waste that rainwater would push into the Santa Ana River system. Over the years, SAWPA built the Inland Empire Brine Line which is a network of pipes that collects high dissolved solids water from the upper Santa Ana River watershed and transports it to OC San’s Plant No. 1 in Fountain Valley. OC San diverts this unreclaimable flow to Plant No. 2 in Huntington Beach, treats it, and safely discharges this flow through its Ocean Outfall. This flow is deemed unreclaimable based on our agreement with OCWD because effluent from a superfund clean-up site in Riverside is included in the flow. This cooperative effort removes more than 500,000 pounds of salt per day from the Santa Ana River system. Imported water from the Colorado River tends to have a relatively high dissolved solids, or salt, content compared to potable standards. While this is acceptable for initial use, reuse of this water will build up salts over time. Water in the San Ana River that was imported by upstream users may be used several times before being recharged in aquifers along the Santa Ana River system. SAWPA, through its member agencies, removes salts from otherwise unusable groundwater supplies to render them potable and dispose of the concentrated salts in the Inland Empire Brine Line for eventual ocean disposal. The Groundwater Replenishment System is the purest source of water to the groundwater basin in central and northwest Orange County. The use of a reverse osmosis water treatment step removes dissolved solids from the product water. The concentrate from the reverse osmosis treatment step is disposed of through OC San’s Ocean Outfall, resulting in the removal of more than 1.3 million pounds of dissolved solids, or salt, per day. Current Situation: OC San is committed to using its existing infrastructure to maintain or improve the quality of the potable water supply within its service area. We do this through our partnerships with OCWD and SAWPA. OC San accepts OCWD’s reverse osmosis concentrate free of charge for ocean disposal through OC San’s Ocean Outfall. The Groundwater Replenishment System is currently fully built out with no additional capacity planned in the future. In addition, OC San has created a dedicated, unreclaimable flow stream from the Inland Empire Brine Line to the Santa Ana River Interceptor to Plant No. 2 in Huntington Beach for treatment and disposal through OC San’s Ocean Outfall. SAWPA has a purchased capacity of 17 million gallons of water per day with the contractual opportunity to purchase up to 30 million gallons of water per day. SAWPA pays OC San based on the daily flow, biological oxygen demand, and total settleable solids of the water. It does not pay based on the total dissolved solids or salt content of the water. SAWPA intends to maximize the flow of water to 30 million gallons per day and maximize the total dissolved solids, or salt, content in the future. The current 50-year agreement between OC San and SAWPA expires in 2046. Future Policy Statement OC San will continue to partner with OCWD and SAWPA to collect and dispose of naturally occurring dissolved solids, or salts, through its Ocean Outfall system in an environmentally responsible way for the benefit of the potable water supply in its service area. OC San will continue to work transparently with Federal and State regulators to assure that the ocean disposal of its effluent, including salt, isn’t having an unacceptable negative impact on the ocean environment. OC San will balance the benefits of water reclamation/reuse and lower volume/higher concentration of salt to the ocean environment. OC San will continue to invest in the long-term maintenance of its Ocean Outfall system to preserve this vital infrastructure. Initiatives to Support Progress Toward the Policy Goal • OC San will continue to invest in the maintenance of the Ocean Outfall system to assure long-term viability. • OC San will maintain a National Pollution Discharge Elimination System Permit that supports treatment operation and safe outfall disposal of Groundwater Replenishment System reverse osmosis concentrate and dissolved solids from the Santa Ana Watershed. • OC San will support the Santa Ana Watershed Project Authority strategic planning process to support watershed salt management through 2046 and beyond. 58 | Strategic Plan — 2025 59 | Strategic Plan — 2025 WastewaterManagement 60 | Strategic Plan — 2025 61 | Strategic Plan — 2025 Chemical Sustainability Policy Summary Policy Statement The Orange County Sanitation District (OC San) has a need to use chemicals in its treatment process to improve plant performance, reduce odor and corrosion potential, and meet its regulatory requirements. These commodity chemicals are provided by outside vendors through the purchasing process. Some of these chemicals are subject to price swings due to market condition changes such as energy cost impacts, raw material cost changes, commercial competition changes, and transportation cost volatility. OC San will identify chemicals key to its operation, investigate the market risks for those chemicals and devise strategies to mitigate identified risks to availability and pricing. Background OC San’s treatment plants and collection system use several bulk chemicals. A sustainable supply of these chemicals is critical to maintaining an acceptable level of treatment and for ensuring compliance with all regulatory requirements. OC San spends about $ 27 million annually on the procurement of eight key chemicals which generally can be broken down into four categories: coagulants, odor/corrosion control, disinfection, and boiler water treatment. Boiler water treatment chemicals are low volume and readily available and will not be considered here. Coagulant Chemicals Coagulant chemicals include ferric chloride, anionic polymer, and cationic polymer. These chemicals are the workhorses of the sewage treatment process. Coagulant chemicals work to clump together organic material so it can more readily be separated from water. Ferric chloride is the first chemical added in the treatment process. It is a powerful settling agent that causes organics to clump together and settle to the bottom of primary basins. It is a double-duty chemical in that it also controls the formation of hydrogen sulfide gas, which is a major odorant, by binding to suspended sulfur compounds and causing them to settle before they can be converted by natural bacterial processes to hydrogen sulfide. Ferric chloride is an iron salt that is produced by reacting iron with hydrochloric acid. It is generally a byproduct of steel treatment, a leftover pickling agent. Ferric chloride is commonly used in the water and wastewater industries. Historically, this chemical has been the subject of a limited supplier base in Southern California. OC San has been actively splitting supply contracts to multiple vendors to ensure multiple vendors are available. On-site generation of the chemical is impractical due to the hazardous nature of the manufacturing process and acid handling, the bulk steel handling logistics, and waste products disposal. Anionic polymer works with ferric chloride to further aid in the coagulation or settling of organic compounds in the primary treatment process. These long-chain molecules are designed to be negatively charged to attract or collect positively charged ferric chloride induced organic clumps or flocculant. The use of ferric chloride and anionic polymer is called Chemically Enhanced Primary Treatment or CEPT. OC San has been using CEPT for more than thirty years. Anionic polymers are specially designed chains with many potential variants and multiple vendors. Part of the purchasing process for polymers involves polymer trials to document the efficacy of different products from different vendors to get the best cost-performance balance. Cationic polymer is generally used to thicken sludge or biosolids in centrifuges or dissolved air floatation thickeners (DAFT). These long-chained, positively charged molecules are essential to the proper operation of centrifuges and DAFT units. Part of the purchasing process for these polymers also involves polymer trials to document the efficacy of different products from different vendors to get the best cost-performance balance. It is important to note that it is entirely possible that four different cationic polymers will be used to optimize the performance of Plant No. 1 dewatering centrifuges, Plant No. 1 thickening centrifuges, Plant No. 2 dewatering centrifuges, and Plant No. 2 DAFTs, because the performance can vary greatly depending on the equipment or process. Each process will have its own polymer trial to determine the cost-performance balance for each application. Odor Control Chemicals OC San uses several chemicals in the collection system and the treatment plant to reduce the odors normally attributed to sewage and sewage treatment. These chemicals can either prevent the formation of odor causing compounds, called odorants, or they can destroy odorants that already exist. Chemicals that prevent the formation of odorants include ferrous chloride, calcium nitrate, magnesium hydroxide, and caustic. Chemicals used in the collection systems tend to be more benign than chemicals used in the treatment plants due to their proximity to the public. Ferrous chloride is closely related to ferric chloride as described above. It is a powerful settling agent that prevents the formation of hydrogen sulfide by tying up and settling sulfide compounds in the collection system. It is a preferred chemical because of its dual role, but it is not as benign as other choices. Calcium nitrate is another choice for collection system odor control. It works in a different way. Calcium nitrate alters the biological equilibrium in sewage. Generally, bacteria that live by respirating oxygen are the most robust organisms, followed by nitrogen respirating bacteria, and finally sulfur respirating bacteria. Adding calcium nitrate to sewage creates an environment where sulfur loving bacteria do not thrive or create hydrogen sulfide. Magnesium hydroxide is a third choice for collection system odor control. It works primarily by raising the pH of sewage to a point that is not conducive for odor causing bacteria to thrive. Magnesium hydroxide is the most benign of the chemical choices as it is the main ingredient in Milk of Magnesia. All three of these chemicals are continuously fed into sewer systems at different points to consistently control the formation of odorants in the system. Where OC San does not have the ability to site a chemical dosing station and persistent odors are being experienced, there is the option to utilize caustic slug dosing. Caustic slug dosing involves using tanker trucks to discharge up to 6,000 gallons of sodium hydroxide into a sewer manhole structure. The very high pH has the effect of killing the biofilm layer and increasing the solubility of hydrogen sulfide in sewer pipes. This treatment has an instant benefit that reduces hydrogen sulfide production from days to weeks depending on system conditions. The final major odor fighting chemical is bleach. Bleach is used in treatment plant chemical scrubbers to oxidize odorants in air scrubber units. Bleach is an effective oxidizer of hydrogen sulfide, methyl mercaptan, methyl disulfide, dimethyl disulfide, and many others. 62 | Strategic Plan — 2025 63 | Strategic Plan — 2025 Disinfection After a significant amount of work with the regulators, and noticeable degradation of the ocean environment, OC San successfully discontinued disinfection of its effluent to the long outfall in 2015. This means that thousands of gallons of bleach and sodium bisulfate are no longer required to be purchased or discharged to the ocean. However, in the event of a discharge to the short outfall or river overflow, disinfection by bleach will be required. Significant on-site storage of bleach and dechlorination chemical, sodium bisulfite, is necessary for this emergency contingency. Process Specific Chemicals OC San uses pure oxygen to support its activated sludge secondary treatment process for Plant No. 2. OC San previously self-generated pure oxygen using a cryogenic oxygen plant rated at 70 tons per day. This plant was removed because it was inefficient at the current average utilization of 35 tons per day and was at the end of its useful life. OC San has evaluated the potential of generating pure oxygen in the future with a different technology that is appropriately sized. OC San contracts for delivery of liquid oxygen and uses a vaporization system to deliver pure gaseous oxygen to the activated sludge process. Chemical Supply — Purchase vs. Make OC San has relied on purchasing bulk commodity chemicals for its treatment plants and collection system. This has proven to be an effective strategy for operational flexibility and to allow concentration on core business. Operationally, the types and volume of chemicals change over time. Over time the types of polymers that are most efficient change. The volume and dosing of chemicals is based on sewage flow rates, sewage composition, and flow splits between plants. Managing the generation of specialized chemicals using hazardous materials imposes a significant training burden on staff, increases regulatory oversight and requirements, and increases overall risk to the organization. OC San maintains a policy to split the volume of orders between two vendors to assure competition exists in the marketplace for ferric chloride. While OC San generally cooperates with other public agencies to pool purchasing power to secure the lowest possible cost through high volume purchasing, some specialty chemicals like ferric chloride require split orders to maintain competitive market forces. Current Situation OC San is constantly changing and improving its facilities to meet new challenges. Each of the facility changes offer new opportunities to reconsider how OC San operates its processes and how chemicals are used. Staff consistently monitor and adjust chemical usage to ensure process performance aligns with permit requirements. OC San has completed a Chemical Resilience Study, which includes contingency planning for chemical substitution during emergencies. Additionally, OC San remains proactive by exploring new technologies to optimize chemical usage. Future Policy Statement OC San will thoroughly understand its treatment processes, the potential modes of operation, and the benefit and cost of chemicals to improve or stabilize its process. OC San will maintain a list of necessary chemicals for optimal treatment operations which will consider chemical cost, chemical availability, treatment stability, energy utilization, energy creation, nuisance odor control, biosolids generation/cost, and regulatory permit compliance risks. Chemicals that are deemed most beneficial will be procured at the lowest overall cost from market providers to the extent possible. Where there are market stability concerns, the purchasing division will devise procurement strategies to mitigate procurement risks. Where procurement risk cannot be satisfactorily mitigated, technical staff will evaluate alternatives such as alternate operating methods, substitute chemical usage, or on-site generation of a chemical if feasible. Initiatives to Support Progress Toward the Policy Goal • Reduce the exclusive reliance on particular chemicals and/or individual vendors to establish flexibility while accomplishing operational objectives. • OC San has evaluated the potential for generating pure oxygen onsite and will be initiating a Capital Improvement project to develop and maintain an oxygen generation facility, reducing reliance on the delivery of liquid oxygen by truck. 64 | Strategic Plan — 2025 65 | Strategic Plan — 2025 Biosolids Management Policy Summary Policy Statement The Orange County Sanitation District (OC San) will sustain the biosolids program and will continue the beneficial reuse of biosolids in accordance with Resolution No. OC San 13-03 and the 2017 Biosolids Master Plan. Background Wastewater treatment, at its most basic level, is the separation of water and solids it carries by gravity and biological means. Since the 1950s, OC San has used anaerobic digestion to reduce the volume of solids, create renewable energy, and create a residual product suitable for agricultural reuse. Anaerobic digestion reduces the volume of solids by 65 percent by converting organic material into biogas, which is a mixture of carbon dioxide and methane gas. This gas mixture powers OC San’s Central Generation Engines at each treatment plant which provide electrical power and heat to our reclamation plants. The remaining 35 percent of the solids material are converted by time and temperature into Biosolids. OC San produces approximately 500-600 wet tons per day, at 23-28 percent solids concentration. OC San’s biosolids program is developed in compliance with federal, state, and local regulations, OC San’s biosolids policy (Board Resolution 13-03), biosolids management system, and the 2017 Biosolids Master Plan (Plan). It consists of the following key initiatives: • Develop an adaptive and highly effective biosolids program emphasizing diversification and beneficial reuse options and markets. • Provide a framework for identifying reliable, sustainable, and cost-effective biosolids management options. • Foster innovation and continuous improvements to OC San infrastructure. • Ensure regulatory compliance. OC San’s adaptive and highly effective biosolids program emphasizes diversification of beneficial reuse options and markets for biosolids. Although cost is a key consideration, the incorporation of failsafe options is considered paramount. These principles align with the policy and Plan to provide a framework for identifying and adopting reliable and sustainable biosolids management options while minimizing cost. Moreover, through innovation and continuous improvements in biosolids management practices, OC San has been well-positioned to sustain regulatory compliance and commitment to beneficially reuse biosolids. Currently, about 54 percent is used to produce Class A compost in California, and about 46 percent is used for Class B land application in Arizona. Current Situation The legislative and regulatory landscapes in California are changing regarding organics management. Since 2003, direct land application of Class B biosolids in Southern California has largely been prohibited due to strict ordinances and conditional use requirements that preempted state recycling laws. However, in recent years there has been a greater focus on healthy soils, renewable energy, organics diversion from landfills, and reduction of Greenhouse Gases (GHGs), which are reflected in several bills and initiatives that have been adopted: • AB 1826 (2014) — Mandatory Organics Recycling for Businesses. • SB 1383 (2016) — 50 percent organics diversion from landfill by 2020 and 75 percent by 2025, which includes biosolids and mandatory organics procurement (compost and biogas) for impacted jurisdiction. • SB 32 (2016) — 40 percent Reduction of GHG below 1990 levels by 2030. • SB 100 (2018) — 50 percent renewable resources (i.e., anaerobic co-digestion of food waste) target by December 31, 2026, and to achieve a 60 percent target by December 31, 2030. • Increasing soil carbon and carbon sequestration under the Healthy Soils Initiative and Forest Carbon Plan. In combination, these measures are expanding the supply to the “organic waste markets”, thereby stimulating interest in siting more composting facilities and organic waste-to-energy projects. The organic waste market in California is composed of food waste, green waste and biosolids. Agencies such as the State Water Resources Control Board (SWRCB), CalRecycle, California Department of Food and Agriculture, California Air Resources Board, and California Energy Commission are developing regulations to implement the new laws. Throughout the rulemaking process, OC San has been actively involved through the California Association of Sanitation Agencies (CASA) and the Clean Water SoCal (formerly Southern California Alliance of POTWS, SCAP) to encourage regulators to work across their narrow interests to optimally reuse organic waste products. CASA, in coordination with CalRecycle, has met with counties in California to restrict enforcement of local ordinances on land application of biosolids that are unreasonably restrictive or prohibitive, thus paving the way for more local biosolids management options. It is worth noting that, while there is growing interest in California for enhanced organics management, there has also been a rising concern from the regulatory community regarding emerging contaminants such as Per- and Polyfluoroalkyl Substances (PFAS) and microplastics. These ubiquitous, often household compounds have been detected in the wastewater pathway and biosolids, and OC San has been actively monitoring the development of the science and regulations across all water, wastewater, air, and soil sectors. To date, PFAS regulations have been established for drinking water, and a series of phased investigative orders were issued by the SWRCB to examine the fate and transport of PFAS. OC San was among 249 wastewater treatment plants that participated in Phase 3 of the investigative order and is actively participating in collaborative studies to evaluate the potential impact of PFAS on beneficial reuse of biosolids. In an era where environmental concerns are at the forefront of global discussions, finding sustainable solutions for managing the solids derived from wastewater treatment is more critical than ever. OC San is researching potential alternatives to agricultural reuse of our solids materials. Supercritical Water Oxidation (SCWO) offers a potential alternative to anaerobic digestions, internal combustion engines and biosolids production, and Deep Well Injection (DWI) of biosolids offers a carbon sequestering option to agricultural reuse. The SCWO research is more fully discussed in the Energy Independence Policy, and the DWI initiative is more fully discussed in the Climate and Catastrophic Resilience policy. Future Policy Statement As California’s evolving environmental regulations influence the organic waste markets, OC San will continue to leverage its memberships with various professional/industry associations to encourage local, state, and federal agencies to promote the beneficial reuse of biosolids. Constituents of Emerging Concern Policy Summary Policy Statement The Orange County Sanitation District (OC San) will partner with other agencies, associations, and institutions to support the use of sound science to inform policy and regulatory decisions on constituents (or contaminants) of emerging concern (CECs) at the federal, state, and regional levels. Staff will obtain and maintain current knowledge on CECs under regulatory consideration, including occurrence, analytical methods, regulations, and treatment to support OC San’s mission and regulatory compliance. Background CECs are pollutants that are not necessarily subject to existing regulations but have the potential to pose significant risk to public health and/or the environment. Wastewater treatment systems are generally not designed to remove or destroy CECs but can serve as a pathway for persistent CECs such as Per- and Polyfluoroalkyl Substances (PFAS, commonly known as the “Forever Chemicals”) and microplastics that enter the system from sources such as residential dwellings, commercial establishments, industrial facilities, dry weather urban runoff diversions, and special purpose discharges. In fact, certain CECs have the potential to compromise wastewater treatment and reuse operations, if found at levels that impair OC San’s treatment systems, digester gas utilization, or advance water purification at the Groundwater Replenishment System (GWRS). As with most pollutants, the reduction of CECs at the source is by far the most effective means of safeguarding public health and the environment. However, since the full range of adverse effects associated with each CEC is often unknown until contamination has become wide-spread, OC San routinely coordinates with environmental regulators, industry partners, and community stakeholders to maintain up-to-date scientific knowledge, technological developments, and relevant regulatory and legislative initiatives. It is worth noting that some of today’s regulated pollutants were once considered CECs, such as 1,4-dioxane and polychlorinated biphenyls (PCBs), and OC San is engaged in multiple regional collaborations to continuously increase our collective understanding of pollutant fate and transport and develop integrated water quality improvement strategies. With steadfast support from the OC San Board of Directors, multiple generations of staff have acquired and conveyed considerable institutional knowledge and experience with identifying, monitoring, and reducing CECs through a combination of source control, treatment optimization, analytical innovations, outreach, and responsible reuse and disposal. A key takeaway from OC San’s decades-long experience with CECs is that there is no such thing as ‘away’ for some pollutants. Thus, we must consider CEC management in every facet of OC San operations, with special emphasis on advance planning for source control, beneficial reuse, and responsible ocean discharge. Current Situation OC San has prioritized CEC source control to prevent potential adverse impacts to its mission of protecting public health and the environment. Industrial and certain non-domestic discharges are regulated by OC San’s Pre-treatment Program through a permitting and source control inspection program that enforces OC San’s Wastewater Discharge Ordinance and federal, state, and local mandates. For CECs that are undergoing regulatory development, OC San may choose to utilize interim guidelines and recommended thresholds from federal, state, and local regulatory agencies to safeguard OC San’s ocean discharge and beneficial reuse of water and biosolids. 66 | Strategic Plan — 2025 67 | Strategic Plan — 2025 OC San will also continue to monitor the development of regulations for constituents of emerging concern that may impact the beneficial agricultural reuse of biosolids. OC San’s long-standing leadership role in key professional organizations will continue to ensure timely and meaningful engagement on key regional, state, and national biosolids management policies. OC San will continue to stay abreast of new biosolids management options, technologies, and regional biosolids recycling and renewable energy partnerships within Southern California, especially those that address the removal, sequestration, and destruction of constituents of emerging concern. Based on regulations that emerge in the coming years, staff will update OC San’s biosolids strategy to account for emerging contaminant management. Consistent with the Biosolids Master Plan, staff will work with OC Waste and Recycling (OCWR) to explore regional biosolids management opportunities as well as local solutions to meet SB 1383’s organics diversion mandates, with emphasis on in-county biosolids utilization, composting, food waste co-digestion, and biogas production. Initiatives to Support Progress Toward the Policy Goal • Assess Deep Well Injection to handle up to 100 percent of OC San’s biosolids production as a sustainable and diverse biosolids management strategy with the benefit of carbon sequestration and reduction in transportation costs and impacts. • Partner with other POTW agencies to conduct a feasibility study on a proposed regional biosolids facility in the Inland Empire to address rising costs, regulatory changes, and disposal challenges. • Continue to engage with local, state, and federal agencies to ensure that biosolids will continue to be safely and legally used as a soil amendment. • Continue working with OCWR to explore regional biosolids management opportunities as well as local solutions to meet SB 1383’s organics diversion mandates, with an emphasis on in-county biosolids utilization, composting, food waste co-digestion, and biogas production. • Implement new mesophilic digesters at Plant No. 2, with the option to upgrade to thermophilic, to improve OC San’s operational resiliency against seismic events while enhancing biosolids quality and marketability. Specifically, OC San has worked with regulators at the federal, state, and local levels in advance of CEC regulations to develop special projects that can be incorporated into the National Pollutant Discharge Elimination System (NPDES) Permit to evaluate the presence and quantity of CECs in our final discharge to the ocean and the background levels in the receiving environment. OC San’s current CEC monitoring program includes constituents in the following category: Hormones (7), Industrial Endocrine Disrupting Compounds (7), Pharmaceuticals and Personal Care Products (14), Flame Retardants (9) and PFAS (12). Data from OC San’s ongoing CEC program will be reviewed by the regulatory and natural resource agencies during the next NPDES permit renewal consultations. Over time, OC San’s source control program has been enhanced and updated to meet the needs of GWRS as it underwent expansion to increase water supply reliability for north-central Orange County. Through formal agreements and staff-level coordination, OC San and the Orange County Water District (OCWD) have forged a world-class partnership that currently produces up to 130 million gallons per day (MGD) of purified water. To safeguard this potable reuse effort against CECs and other pollutants that are not removed by conventional wastewater treatment systems, OC San and OCWD established a notification plan that is activated whenever a pollutant or pollutant precursor becomes a concern to either agency. When the source(s) can be identified, and the signal is persistent, consistent, and of sufficient magnitude, the plan outlines the escalation responsive actions that may include outreach and enforcement. A typical response could include source investigation by OC San that begins with data review, accelerated sampling, laboratory analysis, and result in inspections and enforcement actions. CECs from suspected domestic and residential sources are typically addressed by way of educational outreach to the public. CECs that are not removed through the treatment process can also be found in biosolids. At high concentrations, CECs may preclude beneficial reuse of biosolids as soil amendments for non-food crop and force OC San to dispose of biosolids in landfills or pursue costly means of destruction. Thus, responsible legislation and regulations that reduce the production and use of CECs, encourage substitution with less toxic materials, and promote adaptive source control programs are essential for sustaining OC San’s mission and commitments to the community. If source control, education and outreach, or legislative and regulatory efforts are not successful, OC San may be required to implement a technological or operational process change/investment to address a CEC. Future Policy Statement OC San shall align its resources to manage CECs throughout its service area and treatment process to comply with existing and anticipated regulatory requirements and sustain beneficial reuse of treated effluent and biosolids. OC San shall acquire and maintain a high level of subject matter expertise and engagement across the wastewater, water, water reuse, air quality, ocean monitoring, and biosolids sectors to monitor the environmental, operational, and financial threats posed by CECs. OC San shall continue to work with other agencies and professional organizations to develop robust analytical methods and routinely monitor its local limits to shape and comply with regulation to protect public health and the environment. OC San shall continue to implement and update the GWRS Response Plan to sustain effective water reuse and prepare for next-generation CECs and emerging regulatory obligations. Initiatives to Support Progress Toward the Policy Goal • OC San will continue to actively engage water and wastewater stakeholders to stay abreast of the scientific progress and any potential operational and financial impacts of CECs and provide timely briefings to OC San’s Executive Management Team and Board of Directors to facilitate informed decision making. • OC San will continue to develop capacity to identify, detect, quantify, and characterize CEC sources throughout the service area and treatment process to promote source reduction, treatment effectiveness, communication of credible risks, and responsible reuse and disposal. • OC San will proactively establish internal expertise and develop laboratory capability to research the potential impact of CECs on beneficial reuse of water and biosolids. OC San will use science-based knowledge to help shape CEC legislation and regulations to protect the public health and environment. • In the absence of promulgated regulatory limits for specific CECs, OC San will work with regulatory agencies to establish interim source control measures to safeguard its water and biosolids reuse initiatives and ocean discharge against potential adverse impacts If OC San is regulated, we will regulate upstream. 68 | Strategic Plan — 2025 69 | Strategic Plan — 2025 Water Reuse Policy Summary Policy Statement The Orange County Sanitation District (OC San) will seek to beneficially reuse all reclaimable water for potable, industrial, irrigation and environmental uses. Background For over 40 years, OC San and the Orange County Water District (OCWD) have partnered to beneficially reuse treated wastewater from OC San. OCWD, which serves roughly the same service area as OC San, manages and replenishes the groundwater basin in northern and central Orange County, ensures water reliability and quality, prevents seawater intrusion, and protects Orange County's rights to Santa Ana River water. Beginning in 1975, OC San contributed treated wastewater from Plant No. 1 to OCWD for the operation of Water Factory 21, which reclaimed the treated wastewater and injected it along with deep well water into the groundwater basin to prevent seawater intrusion. In the mid-1990s, OCWD needed to expand Water Factory 21. At the same time, OC San faced the challenge of having to build a second ocean outfall pipe to discharge treated wastewater into the Pacific Ocean. Both agencies collaborated to build an advanced water purification facility to resolve these challenges. This state-of-the-art facility, known as the Groundwater Replenishment System (GWRS), took the place of Water Factory 21, and began operation in 2008. The GWRS further processes secondary treated effluent from OC San Plant Nos. 1 and 2 to drinking water standards and uses the purified water for both injection and percolation, through injection wells and recharge basins, as source water to replenish the groundwater basin’s drinking water supplies. With approximately 85 percent of the water demand in northern and central Orange County cities coming from the groundwater basin, GWRS supplements existing water supplies by providing a new, reliable, high-quality source of water. OC San made a considerable investment to improve its level of treatment and source control to support the GWRS partnership. The upgrade to full secondary treatment and shifting the source control regulations, testing, and enforcement from a focus on ocean discharge to drinking water supply was significant. While the original GWRS facility was initially constructed to supply up to 70 million gallons per day (MGD) of purified water, the facility was designed for an ultimate treatment and conveyance capacity of 130 MGD. The Final Expansion of GWRS was completed in December 2022 and can produce a maximum capacity of 130 MGD. OC San, in cooperation with OCWD, operates the largest potable water reuse system in the world. This was made possible by replumbing our treatment plants to segregate non-reclaimable flow and adding a new smaller pump station to deal with low outfall flow rates. In addition to providing treated wastewater to GWRS, OC San also provides treated water to OCWD’s Green Acres Project. The Green Acres Project provides recycled water for landscape irrigation at parks, schools, and golf courses; industrial uses, such as carpet dying; toilet flushing; and power generation cooling. OC San uses reclaimed water and plant water (secondary treated effluent with bleach addition) within the treatment plants to offset potable water use. OC San uses 5-10 MGD of plant water, within the plants for engine and equipment cooling, polymer make-down, equipment flushing and washdown, and other uses. Current Situation The GWRS currently produces up to 130 MGD of purified water,enough water for one million people. All of OC San’s Plant No. 1 secondary effluent and Plant No. 2 secondary reclaimable effluent is made available to OCWD for the GWRS and Green Acres Project. Non-reclaimable secondary effluent from OC San’s Plant No. 2, such as discharges from inland desalters, GWRS’s reverse osmosis process, and OC San’s process sidestreams, are appropriately treated and released into the ocean. With this significant investment and partnership, OC San has a policy to retain all wastewater flow attributable to its collection system. The financing, infrastructure, and operating capacity are in place to convert attributable water equitably into valuable potable water for the region we serve. New water reuse systems for the benefit of smaller, individual development undermine this significant existing investment and equitable distribution of potable water across the service area. Future Policy Statement The treated effluent produced from OC San’s Plant Nos. 1 and 2 is a valuable resource that can help boost local water resources, improve groundwater quality, and reduce dependence on imported water, while reducing the volume of effluent discharged to the ocean. OC San will continue to support GWRS by providing secondary effluent as source water free of charge; allowing OCWD to discharge brine via OC San’s ocean outfall free of charge; leasing approximately 10 acres of land to OCWD at $1 per year for GWRS; and allowing OCWD to discharge North and South Basin extraction well flows to OC San sewers. OC San will continue to maximize the delivery of secondary effluent available to GWRS and the Green Acres Project to maximize full production of purified recycled water for indirect potable reuse, and industrial and irrigational uses. The two agencies regularly communicate and coordinate on operations and construction projects, regulatory compliance, and source water quality to sustain reliable GWRS operations. OC San has adequate flow to maximize the production of GWRS and will work to protect those flows from upstream diversion. Initiatives to Support Progress Toward the Policy Goal • Support the Groundwater Replenishment System and maximize reclaimable wastewater availability to OCWD. • Support the Green Acres project water production to provide reclaimed water for industrial and irrigation uses. 70 | Strategic Plan — 2025 71 | Strategic Plan — 2025 72 | Strategic Plan — 2025 73 | Strategic Plan — 2025 WorkplaceEnvironment 74 | Strategic Plan — 2025 75 | Strategic Plan — 2025 Resilient Staffing Policy Summary Policy Statement The Orange County Sanitation District (OC San) has comprehensive programs in place to attract, develop, and retain high-quality talent to support its mission of protecting public health and the environment. Some of these programs include training and development, employee recognition, diversity and inclusion, recruitment and selection, and competitive benefits and compensation, which help promote employee engagement and productivity to make OC San an employer of choice. Background At OC San, employees are the organization’s most valuable resource. OC San employs over 650 highly skilled and dedicated individuals committed to providing outstanding service to the community, and whose collective efforts make OC San an industry leader. OC San invests in its employees by providing targeted educational and training opportunities, resulting in a highly skilled and educated workforce tasked with carrying out our mission and sustainability of the agency. OC San has a diverse workforce and a wide range of expertise with approximately 70 percent of positions requiring a degree, certification, and/or license. Occupations include scientists, engineers, environmental and regulatory specialists, plant operators, mechanics, construction inspectors, as well as professionals in public affairs, finance, contracts, information technology, safety, and human resources. Effective strategic workforce planning allows management to project the loss of institutional knowledge and experience caused by employee turnover. OC San utilizes a variety of methods to ensure we have access to internal talent pools through effective performance management, talent assessments and training, individual development plans, and external talent pools by actively sourcing for passive candidates and leveraging social media outlets and career fairs. OC San utilizes a competitive recruitment process that prioritizes hiring the best candidate for any given position based on qualifications and merit. Human Resources utilizes an objective multi-hurdle recruitment and selection process which includes screening for minimum qualifications, secondary screening of applications by the hiring manager, assessment centers and skills testing, panel interviews (for technical skills and fit), and a full background investigation and reference check of the selected candidate. OC San utilizes several strategies to attract, develop and retain highly skilled staff for key positions. These include fostering a strong values-based culture, being intentional with our hiring practices, promoting employees’ growth and development, supporting a healthy work/life balance, rewarding and recognizing exemplary achievements, and maintaining a competitive benefits and compensation philosophy, in addition to the following: • Equal Opportunity Employer As an Equal Opportunity Employer, OC San advertises vacant positions to all segments of the public providing a fair opportunity to all. Jobs are generally advertised on the internet, e-mailed to employees, and posted on social media and other industry-specific sites, and in trade magazines or on trade-specific websites for hard-to-fill, specialized, or technical positions. Recruiters utilize LinkedIn and other platforms to reach potential candidates in the labor market. • Vocational and Student Internship Programs Vocational students from local community colleges work 28 hours a week and rotate through five technical trades for 53 weeks within our Operations and Maintenance Department. OC San has experienced success through the program with 29 of the participants hired on full-time since the program’s inception. OC San also offers a Student Internship Program that provides students at local universities an opportunity to work alongside professional staff while attending college full-time for a one-year maximum duration. OC San partners with Cal State Fullerton, Cal State Long Beach, Cal Poly Pomona, Chapman University, and UC Irvine, among others in Southern California. • Employee Training and Development Program In addition to providing all legally mandated training, OC San invests in employee training and development to increase job knowledge and skills, optimize performance in current roles and build a skilled pool of internal candidates for future organizational needs. Comprehensive training programs include legally mandated training, and technical training through industry-specific associations or groups, local schools, and professional associations, including informal on the job training. Employee development is profiled and tracked to ensure compliance with legally mandated training as well as requirements for licenses and certifications. Staff obtains targeted job-related training necessary to keep OC San current with industry best practices and developments in their respective fields of expertise and are eligible to receive development pay for job-related licenses and certifications. OC San also provides access to developmental learning opportunities that increase knowledge, skills, abilities, and enhance organizational awareness. The elective development training courses are focused on leadership, technology, communication, OC San business systems, and partnerships for the future. These offerings are designed to address knowledge transfer as attrition occurs and to develop employees from within the organization for succession management and business continuity. Employees may also apply to participate in the Cal State Fullerton 14-week Leadership Academy for Public Agencies. OC San also promotes professional development through its tuition and certification reimbursement programs for courses completed toward obtaining an associate’s, bachelor’s or master’s degree at accredited colleges, universities, or other institutions or industry-specific certifications. OC San’s staffing strategy for difficult-to-fill positions includes investing in employee training and development to build a skilled internal talent pool, particularly when the labor market is not meeting workforce demands. Through upskilling of current employees, OC San can strengthen institutional knowledge and improve retention. Currently there is a limited talent pool, both internally and externally, for state-certified candidates who qualify for the mid-level plant operator positions. In response, OC San will provide an operator certification preparation class to encourage employees to attain higher certification levels, thus qualifying them for more advanced positions for which OC San has difficulty finding qualified candidates. This three-day training is open to the public and includes a plant tour focused on operations to highlight OC San and attract external applicants for these crucial roles. • Mentoring: OC San’s Mentoring Program is built on a collaborative, voluntary relationship between a mentor and a mentee. Mentors are typically more experienced or hold a higher position than the mentee 76 | Strategic Plan — 2025 77 | Strategic Plan — 2025 and are not in the mentee’s direct supervisory line, ensuring objective feedback for professional development. Through the mentorship, the mentor and mentee collaborate to develop actionable and measurable goals that fulfill their development plan. Mentorships take place over five one-hour sessions and are completed within a five-month period. During the mentorship period, mentors provide guidance, support, and advice to help mentees pursue their established career goals. Since inception in 2009, there has been an average of seven to eight mentorships annually. • Partnerships: OC San hosts numerous training sessions on industry specific topics, benefiting not only our employees but also member agencies, local public agencies, and surrounding cities. Additionally, OC San partners with professional associations, such as the California Water Environment Association, to organize certification training events onsite that are open to other agencies. OC San employees volunteer on various commissions and administrative boards for professional associations and participate in advisory councils for both educational curriculum and industry advancements. • Workforce Vulnerability Assessments OC San management conducts a systematic assessment of its workforce to forecast staffing requirements and identify key and vulnerable positions based on three criteria: criticality, retention, and difficulty to fill. Human Resources facilitates annual workforce vulnerability assessments and works closely with departments to identify potential gaps and develop action plans to respond to future staffing needs. • Talent Readiness Assessments OC San evaluates staff readiness for key positions on a regular basis and focuses its employee development efforts based on identified gaps. Key positions and feeder roles are also identified along with the knowledge, skills, and abilities needed to perform these jobs to create Individual Development Plans for employees to enhance their skills in their current roles, prepare to compete for future job opportunities, and ensure seamless movement of talent within the organization. To remain competitive in the labor market and ensure retention of top talent, OC San conducts recurring Classification & Compensation studies to ensure job classifications accurately reflect the work being performed, set compensation levels accordingly, and stay abreast of market benefit and salary data. The process includes feedback from multiple stakeholders including employees, management, bargaining groups, legal counsel, and Human Resources. Current Situation Currently, 55 percent of OC San’s executives and managers are eligible for retirement. In the next five years, the number of eligible management increases to 73 percent. For trades, para-professional, professional and supervisor occupations, 26 percent are currently eligible to retire, and that increases to 44 percent by 2030. OC San has many long-term employees with vast knowledge in their respective areas of expertise. The average years of service is nine years with some employees having been a part of the OC San family for over 35 years. Looking at OC San’s total attrition over the last five years, we have lost 3,614 years of knowledge and experience by 223 individuals leaving the agency since May 2020. In 2010, OC San proactively implemented a second retirement benefit formula (“classic open plan”) ahead of the Public Employee Pension Reform Act, which offered candidates moving from other public sector agencies to OC San a retirement benefit of 2.43 percent at 65, with zero employer paid member contribution. Based on OC San’s classic open retirement plan, competing for experienced and highly skilled talent from surrounding municipalities, who offer a more attractive retirement benefit of 2.5 percent or 2.7 percent at 55 in addition to paying for a portion of the employees’ contribution, has been challenging. In the last five years, approximately 35 percent of new hires come from other public sector agencies. This limits our ability to hire staff who are already trained and experienced, which can be particularly difficult for technical, scientific, and management positions. OC San has recent experience in competing with the private sector labor market, as well as with public sector candidates withdrawing from the process or declining job offers once they learn of the impact to their retirement benefit formula. Given legal restrictions which bind OC San to the classic open retirement formula, it is critical that OC San focus its efforts on retaining current staff, attracting qualified and experienced candidates, and investing in developing and growing employees’ knowledge, skills, and abilities for the future, to address any potential talent shortages. Future Policy Statement OC San will continue to implement strategic workforce planning processes to ensure workforce capabilities match the work required to meet OC San’s current and future needs. OC San will continue to proactively monitor the changing work environment, labor market, and legal landscape to ensure human resources programs are compliant, relevant, competitive, and help promote the behaviors, culture and competencies needed to achieve organizational goals. Initiatives to Support Progress Toward the Policy Goal • Vocational Training — seek out partnership opportunities with vocational training institutions to enhance recruitment options, especially for hard-to-fill positions. Increase the levels of outreach and participation on advisory councils and committees on curriculum for vocational trade schools to ensure the current staffing needs are met. • Identify targeted development for lead-level positions to prepare for future attrition to ensure sustainability into the future. • Maintain and enhance workforce planning initiatives to efficiently and effectively identify, develop, and select the next generation of prepared, capable, and engaged employees through: o Employee Training and Development Programs o Vocational/Professional Student Internship Programs o Workforce Vulnerability Assessments o Talent Readiness Assessments • Continue to build OC San’s centralized training program and evaluate various options to partner with member agencies to share content and network. 78 | Strategic Plan — 2025 79 | Strategic Plan — 2025 Safety and Physical Security Summary Policy Statement The Orange County Sanitation District (OC San) will ensure the safety, health, and security of employees, contractors, and the public through industry best practices, policies, and procedures that support a safe and secure environment, provide an appropriate level of security, and safeguard OC San’s property and physical assets. Background Safety and Health In California, employers must furnish employees with a place of employment free from known or recognized hazards that cause serious physical harm or death, that is compliant with all legal requirements and aligns with industry best practices. OC San is committed to identifying workplace hazards through regular inspection, with the goal of eliminating or providing an acceptable engineering control, implementing administrative controls such as safe work procedures and training, as well as provision of personal protective equipment. Our safety programs ensure the safety of OC San’s workforce, contractors, and members of the public. Emergency Management OC San must be prepared to control risks to the organization, and routinely recognize, evaluate, and prepare for emergencies. An emergency can include an explosion, fire, verified bomb threat, civil disorder, active shooter, or uncontrolled hazardous materials release which interrupt OC San’s ability to provide safe and environmentally responsible wastewater treatment. OC San’s protocol to control and respond to emergencies is outlined in the Integrated Emergency Response Plan (IERP). The IERP identifies and assesses hazards regarding emergency events which OC San may be confronted with. It contains policies, plans, and procedures for preparing and responding to emergencies. When OC San cannot effectively respond to an emergency under routine operations, the Emergency Operations Center (EOC) is activated. OC San’s EOC adheres to the National Incident Management System (NIMS) Incident Command System (ICS) framework, which is a standardized approach to command, control, and coordinate emergency response for incidents of any size. Once the immediate emergency has been controlled, then OC San must resume normal operations. In the event of a prolonged emergency state, the return to normal operations is guided by OC San’s Continuity of Operations Plan (COOP). In May 2018, a COOP was completed with all divisions contributing to its development. The IERP and COOP programs are regularly updated, based on emergency response exercises, or due to changes in plant processes or personnel. OC San collaborates, and has mutual aid agreements in place, with other Orange County agencies to ensure available resources are identified and engaged in the event of an emergency. OC San is a member and funding agency of the Water Emergency Response Organization of Orange County (WEROC), which is administered by the Municipal Water District of Orange County. WEROC supports and manages countywide emergency preparedness, planning, response, and recovery efforts among Orange County water and wastewater utilities. Physical Security The Department of Homeland Security (DHS) has designated 16 critical infrastructure sectors, which includes water and wastewater systems. Wastewater systems are vulnerable to a variety of attacks, including acts of terrorism, contamination with deadly agents, physical attacks, and cyberattacks. In addition, DHS indicates that the average time it takes for a critical incident to take place is up to 12 minutes while the average police response time can be up to 11 minutes, and that time could increase should there be a natural disaster. Additional security concerns include physical violence, vandalism, theft, and trespassers. With a footprint of approximately 100 acres at each plant, and over 650 employees, contractors, and members of the public onsite for tours and meetings, it is essential to maintain a security presence that can respond to security threats promptly. OC San contracts with a security firm that includes armed guards to provide round the clock security monitoring of plant access, doors, cameras, and patrolling the perimeter at both plants. Current Situation Risk Management identifies potential risks to the organization and provides solutions for mitigation or reduction of the risk to acceptable levels. Through this process, the Risk Management Division will create a safe, healthy, and secure environment for OC San employees, contractors, and members of the public. Risk Management partners with management and employees to take ownership of identifying risks and mitigating risks within their sphere of control. Risk Management, managers, and staff collaborate to develop written procedures (e.g., policies) that are used for eliminating and controlling hazards at OC San; thus, ensuring compliance with occupational health and safety standards and laws. Safety OC San strives to achieve safety excellence and continually advance our safety and health culture and associated programs. This is exemplified by our California Voluntary Protection Program (Cal/VPP) designation, which is recognized as a higher level of protection for the workplace. The Cal/VPP is a program created by Cal/OSHA to recognize organizations that have implemented safety and health programs that effectively prevent and control occupational hazards. A Cal/VPP workplace is expected to continually improve its safety program, which means a safe workplace for all. A reduction in injuries and illnesses has been documented at sites that have committed to the Voluntary Protection Program approach. OC San received its Cal/VPP designation in 2023, following a weeklong audit of Plant No. 1’s safety and health management system, which included physical walkthroughs, employee interviews, as well as a review of our safety programs and procedures. OC San utilizes a Safety Incentive Program that recognizes and rewards employees for their improvement of safe work practices, resolving unsafe working conditions, and achieving safety excellence in job performance. The program was revamped in 2022 to make recognition more transparent, flexible, and meaningful to employees and provides a broader selection of awards, ranging from OC San apparel to an assortment of sanctioned products. OC San continues to conduct third party annual comprehensive surveys. The goal of the surveys is to identify regulatory gaps in safety, health, industrial hygiene, and emergency management. Opportunities for improvement that are identified as part of the survey process are tracked to completion. 80 | Strategic Plan — 2025 81 | Strategic Plan — 2025 Emergency Management OC San partners with local agencies to ensure available resources are identified and engaged in the event of an emergency. In early 2025, OC San conducted a functional seismic emergency exercise with field components at Plant Nos. 1 and 2, and remote facilities. The exercise involved coordination, communication, and decision-making within the Emergency Operations Center (EOC), and included real-world, limited physical activities in the field. These simulation exercises are an instrument to train for, assess, and evaluate OC San’s emergency response performance, test our EOC and employee notification capabilities. Security The designation of wastewater systems as critical infrastructure by the Department of Homeland Security requires OC San to be diligent in protecting people and property from security breaches. OC San seeks to continually improve the security program. OC San partners with the Cybersecurity & Infrastructure Security Agency to identify, protect against, detect, and respond to physical and cyber security incidents affecting plant processes. OC San issued a Request for Proposal (RFP) in late 2023 for Security Services, which included the expansion of security services for OC San’s new Headquarters Complex. As part of the RFP evaluation, OC San reviewed and implemented procedural and technical enhancements. OC San’s Security Committee, which includes stakeholders from a cross-section of the organization, continues to meet quarterly to collect input and assess physical and cyber security concerns and suggestions. Responsibilities of the committee include, but are not limited to, reviewing security orders and policies, reviewing security incident reports, and planning drills. Future Policy Statement Risk Management will continue to implement strategic initiatives that will ensure the safety, health, and security of its workforce, and proactively plan for emergencies to ensure continuity of operations. Staff are dedicated to proactively monitoring the changing work environment and requirements to implement programs now that address future vulnerabilities. Assessments of changes in business needs, plant processes, and legal requirements are necessary to ensure a safe and secure work environment. The results of improvement will be measured using leading metric indicators and reported to the workforce to foster employee engagement. Initiatives to Support Progress Toward the Policy Goal Safety • Identify regulatory gaps and opportunities to continually improve OC San’s safety and health management system to maintain the Cal/OSHA VPP designation. • Continue to foster a culture where employees are accountable for their safety, as well as the safety of others. Emergency Management • Support facility and countywide emergency preparedness, response, and recovery efforts by partnering with entities, such as WEROC, Orange County Sheriff Department, and local fire departments to plan and conduct disaster preparedness exercises and drills. • Develop and conduct a comprehensive emergency exercise on a biannual basis to evaluate the effectiveness of systems, processes, and operational efficiency Security • Develop a physical security master plan based on findings from past audits and surveys with a focus on mitigating risk, compliance with applicable regulations and standards, and enhancing security measures in OC San facilities and operations.

FROM:Robert Thompson, General Manager Originator: Mike Dorman, Director of Engineering SUBJECT: ENGINEERING PROGRAM CONTRACT PERFORMANCE REPORTS GENERAL MANAGER'S RECOMMENDATION RECOMMENDATION: Receive and file the Engineering Program Contract Performance Report for the period ending September 30, 2025. 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 30,2025.This report is updated quarterly and includes a summary of the General Manager approved contract contingencies among other key performance indicators.With this release,the report format has been significantly updated with a new look and feel designed to make the information easier to read and interpret.

This document will continue to change in content and structure to reflect OC San’s 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 treatment, while achieving OC San’s mission and vision statements. OC San manages asset reliability, mitigates risk, and ensures the quality of its delivered services according to the following 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. Its collection system infrastructure includes over 380 miles of regional 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 184 million gallons per day, serving approximately 2.6 million people in central and northwest Orange County, California. Figure ES-1.

The following highlights summarize key accomplishments achieved during the last fiscal year: • Condition Assessment Program: The Asset Management Team completed approximately 38 condition assessments during the last fiscal year, spending nearly $1.1 million. Annual expenditures on condition assessments have been increasing year over year, 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. • Collection System Asset Management Activities: Proactive efforts are underway to address isolated and severe defects in the gravity collection system by grouping similar asset issues for efficient execution of solutions. Services are being procured for cleaning and sonar inspections of inverted siphons and large-diameter pipelines. OC San also continues to improve the use of the recently implemented Info360 Asset software by refining risk and decision models over time and also moving to high-definition video for all new inspections. Three pump station valve replacement projects have also been completed, with two more projects in progress. A more robust program for force main inspections has also been implemented. • Treatment Plant Projects: Several key projects were completed including improvements to central generation engines, Dissolved Air Flotation Thickeners (DAFTs) A and D, various pumps, Trickling Filter Clarifier B, truck loading scales, and short-term improvements to the A-Side Primary Clarifiers and Grit Basin cables. Ongoing efforts are 2025 Asset Management Plan ES-12 addressing critical needs such as variable frequency drive replacements, clarifier rehabilitation, digester gas dryer and heat exchanger moisture separator replacements and instrumentation upgrades, pump overhauls, and additional engine overhauls at the Central Generation Facility. • Planning Studies: Three major planning studies—Central Generation Digital Twin, Energy and Digester Gas Master Plan, and On-site Oxygen Generation Feasibility Study at Plant No. 2—were successfully completed to guide future reliability and sustainability initiatives. 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 for robust planning purposes. The FY 2025–2026 Budget Update, the second year of the 2-year budget adopted in June 2024 and updated in June 2025, includes updates to the 20-year Capital Improvement Program (CIP) outlay. Figure ES-6 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-6. 20-Year CIP Outlay 2025 Asset Management Plan 1 1 Introduction The Orange County Sanitation District (OC San) Board of Directors (Board) developed its mission and vision statements to clearly communicate OC San’s purpose to its stakeholders and to articulate OC San’s organizational objectives. The vision supports the mission by expressing what OC San strives to achieve now and into the future. Through improved and robust asset management practices, OC San is better able to coordinate and plan actions to ensure that all facilities and infrastructure are safe and reliable, and meet the rigorous level of service embodied by its 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 guide 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 and Capital Improvement Program (CIP) projects. • Coordinate the efforts of Operations, Collections, Mechanical Maintenance, Electrical Maintenance, Instrument Maintenance, and Engineering through process teams to ensure that OC San’s resources are focused on the high-priority work functions. 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. 2025 Asset Management Plan 2 • Maintain a 20-year forecast of all CIP projects needed to maintain or upgrade OC San’s assets on a prioritized risk basis to establish rate structures. The AMP is a living document that describes evolving operational strategies, maintenance, refurbishment plans and adaptations, and CIP implementation; it is revised annually 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 assets. • 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 OC San’s 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 its Board of Directors, rate payers, and employees. It includes operational, capital, and debt service expenditures necessary to support its mission and to execute the Strategic Plan adopted by its Board of Directors. The AMP identifies new operational, maintenance, and capital improvement activities for consideration during the budget development process. 2-year Annual 2025 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 northwest Orange County, California. OC San’s two resource recovery and wastewater treatment facilities treated an average daily wastewater flow of 184 million gallons per day (MGD) from residential, commercial, and industrial sources in fiscal year (FY) 2024–2025. In addition to its plant facilities, OC San owns and operates wastewater collection system infrastructure. The OC San collection system infrastructure includes over 380 miles of regional trunk sewer pipelines and 15 pump stations throughout its 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 California Regional Water Quality Control Board and the U.S. Environmental Protection Agency. This authority is established through the National Pollutant Discharge Elimination System (NPDES), which 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. 2025 Asset Management Plan 4 Figure 1-1. OC San’s Service Area 2025 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 northwest 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; these design capacities 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 an 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 High-Purity Oxygen-AS or the Trickling Filter/Solids Contact (TF/SC) secondary treatment process. 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, refer to Appendices C and D, respectively. Solids treatment at Plant No. 2 includes dissolved air flotation thickening of 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.

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. 78-inch Outfall (Discharge Point 002) serves as an emergency outfall and primary backup to the 120-inch Outfall, discharging treated wastewater more than 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. Santa Ana River Emergency Overflow Weirs (Discharge Point 003) is a system with two overflow weirs at Plant No. 2 that discharge directly to the Santa Ana River. These weirs are for extreme emergency use only and serve as a secondary backup to the primary outfall facilities, ensuring the safety and welfare of the community at large. 2025 Asset Management Plan 8 1.2 Asset Management Organization Asset management is an essential part of OC San’s mission to deliver safe, economical, and reliable wastewater treatment services. Every part of the OC San organization is involved in some aspect of managing assets and ensuring that assets are designed, constructed, operated, and maintained to reliably deliver the required level of service to its 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 1-2). Figure 1-2. 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. Asset management activities are performed throughout OC San Operations Maintenance Information Technology Planning Project Management Office Design Construction Management 2025 Asset Management Plan 9 • The 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 Management Office is responsible for the execution of facility 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. • Information Technology supports and maintains the digital platforms and systems that support asset management functions, ensuring data integrity, system integration, and consistent, reliable information across the organization. To fulfill OC San’s commitment to ratepayers to provide safe and reliable services, the 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, plus an engineer specializing in corrosion control who leads condition assessments and coating projects. Staff 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 properly and reliably. The Asset Engineers, each assigned to their respective process or collection system area(s), work closely with associated O&M team members to stay current with the operation, condition, process, and/or maintenance-related issues within their assigned areas. The Operations Team focuses on the optimal utilization of 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 ensuring installed assets are in a ready state for Operations that optimizes planned maintenance and minimizes costs and downtime. Collectively, the area Asset Engineer and O&M work together to reach the goal of providing the required level of service at the lowest life cycle cost with an acceptable level of risk. This strategy involves a significant investment in internal coordination but ensures that OC San is properly assessing risks, solving problems, and processing deficiencies in a timely manner. 1.2.1 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. A major asset can be composed of other assets. For example, a clarifier can be called a major asset, yet 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. 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 impact 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 cause significant disruption to the overall process or system? Is its reliability essential to the plant's operational efficiency? • Does its malfunction negatively impact key performance metrics or targets? • Could its failure compromise safety protocols or create safety hazards? 2025 Asset Management Plan 10 • Does it play a direct role in maintaining regulatory 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 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 Financial Management 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. 1.2.2 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 1.2.3 Asset Life Cycle 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 Life Cycle Curve (Figure 1-3). At OC San, it is understood that detecting potential failure alone is 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 to future designs to improve asset reliability and resistance to failure and minimize maintenance costs. 1.2.4 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, 2025 Asset Management Plan 11 which collects data through condition monitoring to provide real-time performance evaluation of assets. PdM is a proactive approach that minimizes unexpected breakdowns and extends the mean time between failures. It 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 1-3). 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, and improving equipment reliability. Figure 1-3. D-I-P-F Curve and PdM Summary 1.2.4.1 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 amplification camera (measures deflection and displacement) 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. 2025 Asset Management Plan 12 1.2.4.2 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 1.2.4.3 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 1.2.5 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 relevant maintenance activities: • The PM Optimization Group is tasked with conducting in-depth assessments to optimize PM strategies for new and existing assets and to establish maintenance approaches 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 preparing and scheduling 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, 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. 1.2.5.1 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 2025 Asset Management Plan 13 • Equipment rotation program to ensure equipment wear is predictable • Adjusting and aligning mechanical equipment • Rebuilding and regular testing of equipment • Changing of lubricants and filters • Cleaning and torque verification of electrical equipment • Testing electrical power distribution equipment • Testing circuit breakers and protective relays • Calibrating sensors and meters 1.2.5.2 Civil Discipline PM and CM activities include: • Cleaning of civil facilities and pipelines (collection system) • Chemical conditioning of wastewater to reduce corrosion and control odors • Minor repairs • Application and repair of coatings • Maintenance and testing of cathodic protection systems 1.3 Reference Society for Maintenance and Reliability Professionals (SMRP). 2013. Maintenance and Reliability Best Practices. 4th Edition. 2025 Asset Management Plan 14 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 the discipline within that process area. The summaries are for the following components: • Plant No. 1 • Plant No. 2 • Collection System – Pump Stations and Force Mains • Collection System – Pipelines and Manholes The Area Asset Management Summaries include area maps (Figure 2-1 through Figure 2-4) showing the general layout of the process areas or collection system, and tables (Table 2-1 through Table 2-4) with the following fields: • Area No.: Number that corresponds to individual plant asset areas. Plant No. 1 asset areas are numbered 10 to 19, and Plant No. 2 asset areas are numbered 20 to 29. • Area Name: Name of asset area. • Average RUL Score: Estimated average RUL score for each discipline (civil, structural, mechanical, electrical, and instrumentation) or area based on an average of the RUL scores provided in the detailed Area AM Summaries. • Percentage of RUL Scores with 4s or 5s: Percentage of major assets with a RUL of 10 years or less. 2025 Asset Management Plan 15 AREA ASSET MANAGEMENT SUMMARY – PLANT NO. 1 OVERVIEW Figure 2-1.

Some assets have very little remaining life or have failed already and will need interim solutions before they are addressed by the project, 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 failures and leaks in 2024 (Sunflower and Santa Ana River Interceptor [SARI]). O&M is also experiencing issues with the flow meters being inaccurate. Condition assessment of each trunkline and repairs were performed between August 2024 and January 2025 to extend the useful life of the piping. Instrumentation team is assessing and replacing the troubled flow meters. 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. Pump no. 1 and associated supporting equipment have been replaced by FE19-04, but pump no. 2 is experiencing issues with bearings, gear boxes, and grease system. These assets in the pump station are approaching the end of their useful lives. The gates are leaking, and the pump station structure also has coating failure and concrete deterioration along with rebar corrosion. Maintenance continues to monitor, repair, and replace parts as needed to keep pump no. 2 in operation. FR1-0026 will rehabilitate the pump station outlet channels to repair the concrete, rebar, and coating in 2026/2027. FE25-01 will replace pump no. 2 and associated supporting equipment, similar to FE19-04, with construction starting in 2027. P1-105 will replace gates and T-lock. All of these projects will provide a complete rehabilitation of Sunflower Pump Station. Wastehauler Station – The automated sampling systems installed by FE20-01 continues to experience 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 Instrumentation group has been providing support and working with the vendor to troubleshoot these issues and keep the Wastehauler Station in operation. 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.

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, causing significant interruption to operation. The center feed channel was cleaned and inspected in 2024; repairs were made to the T- lock liner to extend the useful life of the structure. The primary basins 17–31 west side effluent channel and pipe are being inspected during the preparation of this document to ensure they remain free of obstructions, allowing for smooth and reliable operation during the upcoming wet weather season. 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. FE23-05 will replace the obsolete scum pumps to improve scum pumping reliability and availability. These projects 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. Primary Treatment Area Programmable Logic Controller (PLC) Obsolescence – Existing PLCs are obsolete. Maintenance has stockpiled parts and will continue to repair/replace as needed. Obsolete PLCs will be replaced as part of future projects in this area. 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 measure. It is also recommended to install a de-ragger on one of the pumps to test compatibility with this service. MP1-003 has replaced 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. The project is currently in the commissioning phase. 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. Primary Effluent Pipe Conditions – A recent condition assessment of the West Primary Effluent Pipe revealed that most of the PVC pipe joint liners have failed and several pipe joints have also failed as groundwater was observed to be infiltrating the pipe via these joints.

Exposed conduit outside of the fence line was cut and wire stolen. Project MP1-008 was completed in 2025 and installed new lighting to improve nighttime visibility and deterrence. Damage and copper wire theft were found at several cathodic protection test stations for the 66- inch, 84-inch, Interplant Digester Gas Pipeline (IDGP), and fiber optic cable facilities along the Santa Ana River Trail. The damaged cathodic protection test stations were repaired in 2025 including installing flat bars and special locking bolts for adding security. The fiber optic handholes were also repaired and full functionality restored. N/A Project SC23-02 will address security issues at EJB by replacing existing fencing with a higher-security fencing system and enclosing exposed conduit with new fencing. Interplant Digester Gas Pipeline Deficiencies – Surface corrosion of varying severity has occurred in all blow off vaults. Other deficiencies include water intrusion in Vaults 1–4, Vault 4 outside existing utility easement, access difficulties to Vaults 8 and 9, structural damage to Vault 10, lack of dedicated blowdown valves, and lack of pressure relief between the Department of Transportation valves. N/A Project FRJ-0003 will repair, replace (or relocate), and abandon blow off vaults. The project also includes installing blowdown valve manifolds and pressure relief for the IDGP. Santa Ana Corridor Soil Erosion – Soil loss has been occurring in the unprotected slopes along the interplant utility corridor paralleling the Santa Ana River for many years. Soil erosion is directly affecting blow off Vault 5 on the IDGP. There are significant reaches of pipeline that appear to lack adequate cover for pipeline protection. OC San has approved a new planning study, PRN-00935, to perform a slope erosion analysis with various field investigations; review slope stabilization alternatives; and identify, compare, and rank conceptual design alternatives. This effort includes developing a new plan and profile for the pipeline to pinpoint areas of inadequate cover and provide the basis of design to resolve the issue(s). Based on the recommendations of PRN-00935, a proposed improvement project will be developed to construct permanent improvements. The future improvement project must at least be started prior to OC San’s next audit with the California Public Utilities Commission in 2032. PEJB-1 Condition – The sluice gates in PEJB-1 are in very poor condition and no longer properly seal. The PEJB-1 structure is also in poor condition. N/A Rehabilitation of the PEJB-1 structure and replacement of existing sluice gates with new ones are included in the scope of Project P1-126. 66-inch Interplant Pipeline Condition – The 66-inch pipelines between PEJB-1 and EJB are in poor condition per the 2021 condition assessment. Conditions have not changed significantly since 2009. The 66-inch pipelines between EJB and Ocean Outfall Booster Station (OOBS) that were not sliplined are also in poor condition. Perform a new condition assessment of the 66-inch Interplant Pipeline between PEJB-1 and EJB in 2026.

Maintenance purchased and received two new bar screens. Bar screen #3 is currently in the process of being replaced with one of the new ones. The other will be available as a shelf spare. O&M plans for more frequent flushing and planned maintenance to prevent and minimize damage to parts. Washer Compactor Redundancy – On August 21, 2021, Plant No. 2 experienced a slug of rags that plugged two washer compactors. An additional plugging issue occurred on one of the units on February 14, 2025, which was challenging to address due to the many man hours required by Maintenance to unplug the unit. With the plant operating in separated mode following the completion of P2-122, redundancy has been reduced, with one swing unit on standby available for the non-reclaimable or reclaimable stream. Continue to address plugging through Maintenance work orders and performing PMs. An emergency mechanical services contract will be bid in fall/winter 2025 to provide an additional labor resource to expedite response and mitigation time for future issues. Planning Study, PS24-07 is currently in the development phase to bid an engineering consultant in fall 2025. The study will research and develop concepts to increase redundancy to the system by adding a fourth unit, identify newer washer compactor equipment models that are less prone to plugging, and provide other options to increase the reliability of the washer compactor system and provide a feasible solution. Main Sewage Pump (MSP) Vibration Monitoring System – The current vibration monitoring system is obsolete. It needs to be modernized to continue to protect both pumps and motors. The Reliability Group uses infrared thermometers to measure temperature of the asset and manual vibration readings to cover the deficiency. FE24-07 is currently in the development phase to bid an engineering consultant to assist in replacement of the obsolete system with the Bently Nevada Orbit 60. Main Sewage Pumps Condition – The five large main sewage pumps and warehouse spare pump have worn parts and are in need of repair and replacement of parts such as mechanical seals, bearings, shaft sleeves, and O-rings. MSP-7 failed in operation after being out of service during repair of the VFD. The MSP was transported to a pump repair facility for inspection and repairs under a maintenance work order. Continue to monitor and provide short-term maintenance repairs. MP2-018, Main Sewage Pumps Repair at Plant No. 2, is in progress with a pump repair facility to make repairs on the spare large pump and MSP-1. A future project will be requested to apply similar repairs to the remaining MSPs (5 and 6).

Aluminum dome supports for A-Side Primary Basins E and G are corroded. Currently, Basins F and G are not available due to loss of structural integrity from severe corrosion of the rotating mechanisms. Availability of A-side basins is critical to process non-reclaimable flow until P2-98A commissions four new primary basins. FE23-09 (formerly MP2-007) is in progress to 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 Clarifier 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. A main component of primary clarifier operability is the rotating mechanism drives. In April 2024, Maintenance staff observed noise from the drive at Primary Clarifier N, and OC San coordinated efforts for the Original Equipment Manufacturers (OEMs) to provide an assessment and identify issues. Condition assessments are currently being conducted on each clarifier, including its rotating mechanisms, to verify RUL and timing of the P2-133 project, and to identify short-term projects to be completed ahead of P2-133. Assessments are scheduled to be completed by fall 2025. PRN-1020 will replace three clarifier drives (J, P, and Q) with new drives. The existing drives will be rebuilt to replace two other B/C-side clarifiers, selected based on criticality. The remaining rebuilt drive will be retained as a shelf spare. Following the OEM’s assessment on the drive for Primary Clarifier N and recommended replacement of the drive, MP2-023 is currently in progress to replace the drive. P2-133 will provide long-term rehabilitation on B- and C-side 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. One gate will be repaired and have seals installed as a test. The remaining gates will be repaired following a successful installation/test under the Planning task order. P2-133 will provide long-term rehabilitation on B- and C-side 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 Box 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. Instrumentation is obsolete and parts are no longer readily available. The replacement of instrumentation and associated electrical has been added to Project P2-135, Chemical Systems Rehabilitation at Plant No. 2. The full system will be replaced under P2-133.

Perform condition assessment of the discharge header and replace the pipes as incidental repair. Pump #3 discharge header condition assessment and replacement completed in 2025. FE19-08 (combined with FR1-011) will replace the PEPS VFDs. MP2-0010 is scoped to overhaul Pumps #1, #2, and #3. Pump #3 was completed in Aug-2025, Pump #1 will be removed in fall 2025, and the Pump #2 overhaul will start in 2026, when Pump #1 is back online, and be completed in 2027. (Pump #4 overhaul was completed in 2022.) X-052 will replace the PEPS pumps with all electrical works including switchgears, rehabilitate the major discharge header, and replace the missing flapper gates. Aeration Basin Reliability – Concrete deck cracking and structural integrity concerns; aerator motor corrosion and oxygen piping corrosion; aged oxygen analyzer panels and no air conditioning. 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 – Collapsed mechanisms in Clarifiers D, G, and L; unsafe access into clarifier basins; scum accumulation and nocardia growth issue (scum is currently flowing to WSSPS-A and then is pumped back to PEPS to keep it in the non-reclaimable stream); some handrails do not meet Occupational Safety and Health Administration (OSHA) requirements. A temporary bleach tote was installed for injection to WSSPS wet well for nocardia control. Maintenance will route a permanent bleach line to replace this tote. A vactor truck will remove scum. FR2-0031 will provide a temporary solution to reroute the scum to DAFTs. P2-136 will replace the non-compliant handrails. FE24-10 will rebuild Clarifiers D, G, and L and add an alignment monitoring system. P2-143 will route WSSPS-A discharge to the new A-side primary basin. 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 (FR1-011) will replace 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 conditions. Liquid Oxygen (LOX) Supply and Storage Issues – 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 until Tank B replacement. FE21-07 is in the final completion phase of construction for Tank A replacement. FE22-02 is in the construction phase to replace LOX Tank B. P2-142 will install Vacuum Swing Adsorption-type on-site oxygen generation 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 flooding; rebuild the main pumps as needed. P2-143 will replace the pumps with dry pit submersible types, and P2-98A will install new discharge piping to route the discharge to the new A-side primary basin. DAFTs Mechanism Corrosion and Lack of Safe Access, and DAFT D Seismic Issues – DAFTs A and D condition assessments found mechanisms severely corroded. DAFT D structure is vulnerable to a seismic event. DAFT mechanisms lack fall protection tie-off points for maintenance activities. Conduct a condition assessment and coat DAFT interior mechanism based on the assessment findings. (DAFT A and D coating was completed in 2025, and coating work will continue in 2026 to complete DAFT B and C.) X-107 will add structural improvements to mitigate seismic risks at DAFT D. FR2-0023 is under construction to install fall protection tie-off points.

N/A J-117B will provide a plantwide load-shedding system to power critical Distribution Center J loads from CenGen. Secondary Clarifier Corrosion and Damage – A condition assessment was done on Clarifiers B and D. Corroded areas have been discovered on walkways and clarifier moving mechanisms. Maintenance projects will repair and replace parts. The Coating Program is working on coating the walkways and moving mechanism parts. X-031 will perform a major rehabilitation of the secondary clarifiers. Return Secondary Sludge (RSS) Pump Damage – Several RSS pumps need to be removed for overhaul due to damage related to clarifier broken parts. Overhauling pumps, repairing clarifier, and purchasing two spare RSS pumps. X-031 will perform a major rehabilitation of the secondary clarifiers. Solids Contact/Sludge Reaeration Biomass Recycling – Using temporary piping to route the area drain pump station to SC/SR basins instead of headworks to keep the microorganisms in the biological process area.

EPSA will function as the secondary backup system, and it will be critical to have a modified maintenance plan to ensure its reliability and readiness for service when needed. 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. The U.S. Environmental Protection Agency recently added NPDES 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 to 7 years. N/A P2-139 scope is being updated to from a rehabilitation project to a replacement project, which will include design to meet current seismic standards. 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 is 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 be used temporarily if needed during construction activities of P2-135 and J-137. P2-135 will replace the sodium bisulfite chemical feed and storage system. Obsolescence of Gate and Valve Actuators – All actuators in Area 24 are obsolete. 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.

Keep Holder K out of service. Minimize shutdown time of Holders I and J. FR2-0032 is under construction to repair the Digester K dome by overlaying polymer concrete based on the condition assessment and structural analysis report. Digester C, D, F, G Mechanical Equipment Reliability – 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. Other pumps and the heat exchangers at the four digesters are also aged and need to be replaced. Heat exchangers have already been purchased and are stocked on site in preparation for FE20-02. FE20-02 is under construction to 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. The remaining gas balance lines were constructed of carbon steel pipes. These gas lines are not meeting the current digester gas line standard of stainless steel and are prone to failure or corrosion. Finish the condition assessment of the carbon steel lines and apply protective coating as necessary based on the findings. FE19-10 is under construction to replace the PVC gas balance lines with stainless steel lines (FE19-10 was combined with FE20-02 as one bid). P2-137 will replace the carbon steel gas balance lines between Digesters P and S. Other replacement needs will be planned based on the condition assessment findings and the remaining years in service. Digesters P and R Structural Issue – The post-tensioned ring has deteriorated, impacting the structural integrity of the concrete domes. Digesters P and R have been taken out of service. P2-137A is in the completion phase to 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 incorporate inspection of the bridges on a regular basis before the repairs. FE19-10 is repairing Digesters F and G and D-I bridges. FR2-0033 is repairing Digester O-T bridge. P2-137 will repair the remaining 13 bridges and replace the Digester Q-R bridge 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. P2-137 will replace one viewport and abandon the remaining two per digester. Digester E and H Flame Arrestors Access – There’s no safe access to do maintenance work on the flame arrestors on the gas balance lines. Maintenance continues to set up a manlift to access. P2-137 will 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 will store spare heat exchangers, sludge recirculation pumps, and bottom sludge transfer pumps. PRN-00684 Maintenance projects will replace heat exchangers, sludge recirculation pumps, and bottom sludge transfer pumps. (Digester E, H, L, M, N and O heat exchanger replacement and E and H pump replacement are 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 Digester I, J, and K interiors. 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 the Biosolids Master Plan to address the seismic risk and provide 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 repairing domes and walls, replacing electrical and motor control centers (MCCs), relocating carbon canisters to ground level, and addressing 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.

RUL < 5 years RUL 5–10 years RUL 11–15 years RUL 16–20 years RUL > 20 years 2025 Asset Management Plan 79 ASSET MANAGEMENT SUMMARY – COLLECTION SYSTEM – PUMP STATIONS Key Issues Key Issues Short-Term Actions and Recommendations Long-Term Actions and Recommendations 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. Especially, 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 collection 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 added another force main to serve the 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 lives sooner than in other applications due to the harsh raw sewage application. These valves are critical to the operation of the collection 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 Slater Pump Station force main was inspected this year. The next planned assessments will occur at the College and 15th Street 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. There is also continued effort to research emerging inspection technologies, which could make difficult inspections more easily achievable or cost effective. 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 control 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. 2025 Asset Management Plan 80 ASSET MANAGEMENT SUMMARY – COLLECTION SYSTEM – PUMP STATIONS Current and Future Projects Project No. Location Project Title Impacted Facilities 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 20 3 9 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, and Edinger Pump Stations PRN-01045 Multiple Pump Station Roof Replacement Westside, Bitter Point, Rocky Point, and Crystal Cove 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 SC22-02 Newport Beach HVAC Replacement for Plant 2 Centrifuge Building, Operations Building, and Bitter Point Pump Station 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 PRN-01042 Newport Beach Lido, Short of Short Street, Force Main Rehabilitation 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 PRN-01054 Newport Beach HVAC Replacement at Rocky Point Pump Station 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-01021 Seal Beach Seal Beach Bridge Force Main Repair 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 buildup, which can negatively impact normal sewer operation and downstream facilities if suddenly released. OC San has historically completed sonar inspections for large-diameter inverted siphons and gravity sewers longer than 5 miles. Sediment reports and hydraulic modeling data were used to confirm the theoretical cleansing state of each pipeline segment inspected. OC San has an active procurement to create a new blanket contract for cleaning and sonar inspection of inverted siphons and large diameter pipelines. The work includes pre-cleaning and post-cleaning sonar inspections to validate the effectiveness of each cleaning. Notice to proceed (NTP) is expected to be issued in early 2026. OC San is developing an ongoing large-diameter cleaning program, and the list of recommended large-diameter inverted siphons and gravity sewers to regularly clean will be finalized in the future. 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. In the future, 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. OC San canceled its initial procurement in 2024 for inverted siphon condition assessment and removed incidental repairs entirely from the project scope due to the low number of bidders and uncompetitive pricing. OC San grouped inverted siphons into planning studies based on risk, location, asset characteristics, and the total rough order of magnitude cost for each grouping. The first study, PS25-01, includes the assessment of seven inverted siphons in the cities of Anaheim, Newport Beach, and Orange. The goals of this study also include evaluating the remaining useful life of each inverted siphon, recommending capital improvements, and identifying the best practices for assessment and rehabilitation of inverted siphons. PS25-01 was launched in 2025, NTP is expected to be issued in mid-2026, and the study is expected to be completed by early 2028. Recommendations and lessons learned from PS25-01 will inform the remainder of the inverted siphon Condition Assessment Program development. Given the potential complexity (bypassing and/or temporary plugging, traffic control, etc.) for inverted siphon inspections, variety in inspection methods that may be required, and different asset priorities, the Condition Assessment Program is currently phased into five additional planning studies. It is anticipated this effort will span over multiple years. 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. Areas with groundwater infiltration that do not have any other defects are lower priority. Projects 1-23, 2-78, 3-60, 3-64C, 5-69, 7-65, 11-35, X-085, X-129, X-130, X-134, and X2-79 will address most 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, an easement area on California Department of Transportation property near I-5 and State Route 91, an easement area encroached upon by residences 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. 2025 Asset Management Plan 85 System Overview - Baker-Main Pipelines ASSET MANAGEMENT SUMMARY – COLLECTION SYSTEM – BAKER-MAIN TRUNKLINE 1 Major Assets and Condition Information - Baker-Main Pipelines Asset Type To t a l L e n g t h (m i l e s ) No . o f P i p e s Av e r a g e A g e (y e a r s ) No . o f P i p e s w i t h R U L Sc o r e o f 5 No . o f P i p e s w i t h R U L Sc o r e o f 4 Vitrified Clay ≤ 18" Ø 18.8 337 58 1 44 > 18” Ø 15.9 245 43 1 24 Reinforced Concrete 15” Ø 0.004 1 32 - 1 > 42" Ø 4.9 50 32 - 3 Ductile Iron 24” - 42” Ø 0.50 3 32 - - Polyvinyl Chloride 10"–21” Ø 0.04 2 23 - - Please see the comprehensive Acronyms and Abbreviations list for definitions. 2025 Asset Management Plan 86 ASSET MANAGEMENT SUMMARY – COLLECTION SYSTEM – BAKER-MAIN TRUNKLINE Key Issues Key Issues Short-Term Actions and Recommendations Long-Term Actions and Recommendations Missing and Undersized Air Jumpers – One out of 10 inverted siphon/reduction locations in the Baker-Main Trunkline system do not have air jumpers. Two out of 10 inverted siphon/reduction locations in the Baker-Main Trunkline system have air jumpers that do not provide adequate air flow capacity and therefore are undersized. N/A Project X-129 includes constructing a new air jumper. Project X-078 includes replacing existing air jumpers with upsized air jumpers or constructing multiple air jumpers in the same location to provide the required air flow capacity. Pipeline Defects – CCTV identified several areas with significant fracturing of vitrified clay pipe (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. 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 – One gravity sewer within Plant No. 1 has never been inspected in the Baker-Main Trunkline system. There is no condition data for this reach to determine field- adjusted RUL. The downstream manhole is currently inaccessible due to construction activities.

N/A Project X-061 includes constructing a new air jumper at two locations. Project X-078 includes replacing an existing air jumper with an upsized air jumper or constructing multiple air jumpers in the same location to provide the required air flow capacity. Three other locations do not require air jumpers due to lack of normal surcharge conditions at two locations and an infeasible location at the end of a force main. Manhole Defects – CCTV identified areas with significant liner delamination and some structures with exposed rebar, primarily in Buena Park, Cypress, and Los Alamitos. Eleven manholes included in Projects 11-35, 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 11-35, X-061, X-085, and X2-79. Projects 3-60, 3-64C, 11-35, X-061, X-085, X-130, and X2-79 will address most 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 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 pipe segment in northern Huntington Beach in 2022. Lastly, one pipeline with fractures also has a very large, encrusted deposit from groundwater infiltration. Root treatment work was completed 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. Projects 3-60, 3-64C, 11-35, X-061, X-085, and X-130 will address most fractures by rehabilitating the pipelines. OC San staff will also coordinate with the City of Anaheim pertaining to operation and maintenance of the local small-diameter sewers OC San maintains for the City of Anaheim under an active agreement. Uninspected Gravity Pipelines – Three gravity sewers have never been inspected in the Knott and Ellis Avenue Trunkline systems. There is no condition data for these reaches to determine field-adjusted RUL. A CCTV inspection was attempted in 2025 for a location upstream of the Steve Anderson Lift Station wet well. The CCTV contractor abandoned the inspection to prevent loss of the camera equipment to highly turbulent conditions, despite OC San staff lowering the wet well level as much as feasible. OC San staff will review inspection technologies as alternatives to CCTV for the gravity sewer upstream of the Steve Anderson Lift Station wet well. There are no known access issues for the remaining two uninspected gravity sewers. Inspections will be completed via future CCTV PM work orders or separate CCTV work 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. 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. 20 manholes between Projects 2-73 and 2-78 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 2-73 and 2-78. Projects FE20-08, FE21-08, 2-73, and 2-78 will address most 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 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. New CCTV inspections are needed for suspected unlined ductile iron pipelines. CCTV inspection frequency will be increased for all ductile iron pipe with polyethylene linings. A polyethylene lining system is not typical and not recommended for ductile iron pipe gravity sewers. Project 2-73 will address all the delamination and tuberculation by rehabilitating the pipelines. Uninspected Gravity Pipelines – Nine 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. N/A All 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.

One manhole in Project 5-69 may reach the end of its useful life prior to construction starting. Manhole coring work and lidar scanning is in progress to perform further analysis and confirm the RUL of the manhole. Project 5-69 will address most of the liner delamination and exposed rebar by rehabilitating the manhole structures. Other manholes are suitable for repair under the manhole repair and rehabilitation repair blanket contracts. Missing and Undersized Air Jumpers – One out of two inverted siphon locations in the Newport Trunkline system do not have air jumpers. The second inverted siphon location in the Newport Trunkline system has air jumpers that do not provide adequate air flow capacity and are therefore undersized. Both inverted siphon locations in the Newport Trunkline system will be inspected under Project PS25-01. Project 5-69 includes the construction of new sewer to replace the inverted siphon. Project X-078 includes replacing existing air jumpers with upsized air jumpers or constructing multiple air jumpers in the same location to provide the required air flow capacity. Pipeline Fracturing – CCTV identified several areas with significant fracturing of VCP pipelines. The fractures are scattered throughout the Newport Trunkline system. Root treatment work is planned to stop root growth and prevent further damage to the pipelines prior to construction of Project 5-69. Isolated defects elsewhere not included or near a CIP project have been identified as high-priority point repairs. OC San staff are in the process of grouping spot repairs together for 7-pack task orders. Project 5-69 will address the fractures by rehabilitating the pipelines. Pipeline Tuberculation – CCTV identified ductile iron pipes in East Coast Highway with significant liner delamination and tuberculation. CCTV inspection frequency will be increased for all ductile iron pipe with polyethylene linings. A polyethylene lining system is not typical and not recommended for ductile iron pipe gravity sewers. Project 5-69 will address the liner delamination and tuberculation by rehabilitating the pipelines. Uninspected Gravity Pipelines – Four gravity sewers have never been inspected in the Newport Trunkline system. There is no condition data for these reaches to determine field-adjusted RUL. For one gravity sewer within Plant No. 2, a CCTV inspection was attempted in 2024 but could not be completed due to flow conditions. It is suspected that heavy flow from the force mains from Bitter Point Pump Station may be the cause of the adverse flow conditions. One gravity sewer in Back Bay Drive is constantly accumulating debris and must be inspected immediately after cleaning. Another gravity sewer upstream of Bitter Point Pump Station is normally surcharged by the pump station’s wet well downstream. The last gravity sewer has no known access issues. OC San staff plans to re-attempt two of the CCTV inspections in coordination with the operation of Bitter Point Pump Station. Additionally, OC San staff plans to re-attempt the Back Bay Drive sewer inspection immediately after a future cleaning. Inspections will be completed via future CCTV PM work orders or separate CCTV work orders.

During existing PWWFs, capacity issues were identified in the Taft Branch. N/A Project 2-49 will address existing wet weather capacity issues in the Taft Branch. 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 most 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 and Undersized Air Jumpers – Four out of 13 inverted siphon/reduction locations in the SARI Trunkline system do not have air jumpers. Two out of 13 inverted siphon/reduction locations in the SARI Trunkline system have air jumpers that do not provide adequate air flow capacity and are therefore undersized. 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. Projects 2-78 and X-078 include replacing existing air jumpers with upsized air jumpers or constructing multiple air jumpers in the same location to provide the required air flow capacity. 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 inverted siphon barrels have never been inspected. Two gravity pipes were re-inspected and confirmed to be unlined ductile iron pipe in poor but not severe condition. Inverted siphon barrels are to be inspected under Project PS25-01. Continued monitoring of the gravity pipes is recommended until the inverted siphon barrels are also inspected. 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 this reach 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.

The metrics have been chosen to directly relate to the Asset Management Program key objectives as follows: • Take a proactive approach to repair, rehabilitate, and replace assets. • 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 OC San’s 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: • Proactive maintenance percent is the percent of PM as a total of all maintenance activities and demonstrates the effectiveness of the maintenance program (proactive versus reactive). The percent of PM includes both 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 proportionate 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 collection system, and the CCTV inspection 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 for FY 2020–2021 through FY 2024–2025 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 targeting around 70 to 80% preventive and 20 to 30% corrective, as these ratios tend to 2025 Asset Management Plan 116 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.

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. Corrective maintenance of high-rate mixing pumps at Plant 1 digesters increased in FY 2024-2025 compared to the previous fiscal year. Major service at the thickening centrifuge spare unit and Dewatering Centrifuge 2 replacement were among the noteworthy tasks at the solids handling facility. Activated Sludge Facility No. 1 is another aging facility at Plant No. 1 that had a higher percentage of corrective maintenance last year. At Plant 2, digesters, solids handling, and Activated Sludge facilities received an increased number of corrective maintenance activities. Overall, the pump stations have proactive maintenance percentages over 50% 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. A Street and Westside and Yorba Linda Pump Stations had a 25% decline in PM work last year. The main 2025 Asset Management Plan 117 issues at pump stations were recurring electrical and instrumentation problems resulting in the significant reduction in PM work. Table 3-3.

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 is a measure of unplanned outages or a reactive maintenance response (service requests with priority 40 and 50 levels). Success in break-in percentage is measured as a consistent downward trend over time. for Plant No. 1 are shown in Table 3-5 and break-in percentages for Plant No. 2 are shown in Table 3-6. The Plant No. 1 Preliminary Treatment Area had a high break-in percent and a decrease in proactive maintenance due to Project P1-105 construction and equipment shutdown demands. Last year, the break-in percentage peaked at 37% in the Interplant area due to vandalism in the area south of Plant No. 1. The Primary Treatment Area has shown relative stability in break-ins. Although there was a slight increase in FY 2024–2025 due to mechanical issues at basins in addition to a reclaimed line break and repairs and the aging odor control facility, the trend is generally stable. Utility break-ins also stayed above 30%, with the majority of issues associated with plant water and 2025 Asset Management Plan 118 reclaimed water line repairs. The remaining areas at Plant No. 1 have shown stable trends with overall numbers below 30%. At Plant No. 2, the data shows an increase in break-in percent in areas with current construction projects and the need for shutdowns and tie-ins, including J-117B. All process areas had break- in percentages within the acceptable range of below 30% at Plant No. 2, with the Solids Handling and Effluent Disposal areas showing improving trends. Table 3-5.

Lido, Seal Beach, Edinger, and College had the most break-ins during the last year mainly due to electrical, instrumentation, and alarm issues. Many aging pump stations, such as Bay Bridge, Edinger, and Slater, also had a high break-in percent that reflects their RUL and age. Bay Bridge and Edinger Pump Stations have replacement projects that are in progress, while Slater Pump Station rehabilitation is scheduled to start in a few years. The Seal Beach Pump Station Replacement Project is currently under construction and is demonstrating lower proactive maintenance activity and a higher break-in percentage. On average, 75% of the pump stations had a break-in percentage of less than 30%. 2025 Asset Management Plan 119 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. The mechanical emergency work increased primarily due to Plant No. 1 headworks and primary treatment mechanical failures. Two major emergency works at Plant No. 1 were the issues associated with Power Building 2 12kV switchgear and headworks MSP-2 repairs. In FY 2024-2025, on average, about 50% of emergency mechanical call backs were to support issues at Plant No. 1, mainly at the solids handling facility to support centrifuges and the cake pump. Plant No. 2 also had the highest number of break-ins at the solids handling facility. Electrical break-in and emergency work is expected to trend down as more electrical projects are implemented to replace or upgrade aging assets (e.g., P1-105, FR1- 0018). 0 50 100 150 200 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 2020 2021 2022 2023 2024 2025 Electrical Emergency Work Orders - Call-Back and Overtime Hours 0 50 100 150 200 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 2020 2021 2022 2023 2024 2025 Mechanical Emergency Work Orders - Call-Back and Overtime Hours 2025 Asset Management Plan 121 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. Solids handling and digesters are consistently high-cost areas. Dewatering Centrifuge No. 3 bearing replacement, major service for the thickening centrifuge spare unit, and repairing digester mixing pumps were among the costliest maintenance activities. The data indicate that there was a large increase in maintenance costs at the Plant No. 1 Primary Treatment Area in FY 2024–2025. Repair of Clarifier 8 and 28 chains and flights and Sedimentation Basin 16/18 sludge pump no. 1 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 by 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 2024–2025, Final Clarifier 18 chain and flight repair, Sunflower Pump 2 bearing replacement and Biotower No. 10 fan repair were among the most labor-intensive activities at Plant No. 1. 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 $2,000,000 Plant 1 Maintenance Cost -Materials & Services FY21/22 FY22/23 FY23/24 FY24/25 2025 Asset Management Plan 122 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 2024–2025 for the trickling filters, primarily due to the replacement of all the three (Trickling Filters A through C) center mast assemblies, which cost around $2.75 million in service charges. West RAS Pump 3 was also damaged last year from excessive vibration, and it was repaired in May 2025 with significant material costs and service charges. In the activated sludge treatment area, Final Clarifier C flight repairs, Gas Compressor #2 service, Bar Screen #4 electrical issue repair, and Activated Sludge Reactors G and H oxygen supply valve replacement were among the most labor-intensive maintenance activities. At the trickling filter area, labor hours remain relatively low compared to other areas, which indicates a less labor-intensive process with fewer mechanical components. 0 1,000 2,000 3,000 4,000 5,000 6,000 7,000 8,000 9,000 Plant 1 Maintenance Labor Hours FY20-21 FY21-22 FY22-23 FY23-24 FY24-25 2025 Asset Management Plan 123 Figure 3-5.

Significant increases in labor and material costs occurred at the Bay Bridge, Bitter Point, and A Street Pump Stations. At Bay Bridge, MSP-2 was repaired, resulting more than $102,000 in total repair cost (materials and services). In addition, MSP-4 was replaced, with more than $25,000 in material costs. Currently, Project 5-67, Bay Bridge Pump Station Replacement, is under construction to replace the existing pump station, which is one of OC San’s oldest pump stations. The new PLC rack installation at Bitter Point was the costliest Work Order in FY 2024–25, totaling $71,000. The pump station also shows high labor hours associated with MSP-5 repairs (Figure 3-8). At the A Street Pump Station, MSP-1 was removed and sent to the rebuild shop for repair, which resulted in a substantial rise in maintenance costs. Figure 3-8 shows an increase in labor hours at the Slater Pump Station compared to last year, attributed to the MSP-2 VFD failure and repair. 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 2024–2025, but the level of service goals for CCTV inspections 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 potential SSOs and prevent them from occurring. Also refer to Section 3.4.2.1 for details on the root control blanket contract for further PM efforts. In FY 2024– 2025, there were zero reported SSOs in the collection system. Nuisance odors are actively managed by the ROCCS program through 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, and other methods 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 for 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.

Since the unexpected departure of its primary pipeline and manhole CCTV contractor in 2024, OC San has restored the full capacity of its pipeline CCTV program and met the level of service goal for CCTV pipeline inspections for FY 2024–2025. OC San could not meet the level of service goal for manhole CCTV inspections for FY 2024–2025, but the procurement for a new primary manhole CCTV contractor was completed in 2025. Therefore, OC San is ramping up manhole CCTV inspections to meet the level of service goal for FY 2025–2026 and beyond. 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 Info360 Asset software for further evaluation and to continue building a comprehensive database of CCTV inspection data. Now that about 2,806 (64%) of OC San’s manholes have been inspected since the start of the manhole CCTV program, OC San can more 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 7,400 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. 2025 Asset Management Plan 127 Figure 3-9. PM Workorder Breakdown by Both Craft and Frequency 3.3.1 Projected Maintenance Costs The projected maintenance costs for the next fiscal year are shown in Table 3-10. 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 $23.07 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 38 different condition assessments during the last fiscal year, spending nearly $1.1 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. 1665 1507 1596 Count of Preventive Maintenance Work Orders by Craft MECH ELEC INST 1043 466 2151 958 399 PM Frequency <6 Month > 6 Month 1 YEARS 2 YEARS 3+ YEARS 2025 Asset Management Plan 128 Figure 3-10. Condition Assessment Contract Expenditures 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: • A condition assessment was completed on the West Primary Effluent Pipe at Plant No. 1 to investigate the high level at the effluent channel and effluent launder weirs submergence during plant peak flow. Failed pipe joint liners were found throughout the entire length of the 108-inch pipe. In a few locations, groundwater was observed to be seeping in through the joint, indicating that the joints have failed at these locations. The pipe was returned to service to alleviate the additional flow being diverted to Plant No. 2 and to bring AS2 back online. However, an expedited repair project is being developed to repair the failed joints, and a future capital project will be developed to fully rehabilitate both primary effluent pipes. • Condition assessments were completed on the Primary Clarifiers J, K, L, M, N, O, P, and Q at Plant No. 2 to assess the condition of structural and mechanical components. Primary Clarifiers H and I will be assessed by fall 2025 for the completion of condition assessments of all B and C side primary clarifiers. These assessments included draining and cleaning of both basins and confined space entry to obtain photographs, take measurements, and collect other assessment data. The assessment identified deficiencies in the clarifiers and provided recommendations on timing to address the issues in the short-term or long-term. Additionally, the OEM of the circular drives provided visual and audible assessments at each primary clarifier with recommended actions to maintain operability. Asset Management also coordinated the effort with support from Maintenance Reliability to obtain drive oil samples for lab analysis. The results provided additional condition data and additional recommendations for drive maintenance. $- $100,000 $200,000 $300,000 $400,000 $500,000 $600,000 $700,000 2020-21 2021-22 2022-23 2023-24 2024-25 Conditional Assessment Contract Annual Expenditures Corrosion Engineer Contractor Support 2025 Asset Management Plan 129 • Condition assessments on anaerobic digesters were completed during the scheduled maintenance cleaning cycle to evaluate and extend the life of the assets when deficiencies are discovered. The condition assessment included confined space entry, corrosion assessment, sludge line cleaning and CCTV, concrete core sampling, and incidental repairs. This year, two digesters were cleaned and assessed, including Digesters 11 and 12 at Plant No. 1. Incidental repairs were completed by the condition assessment contractor and Maintenance staff. Gas balance lines and digested sludge conveyance lines at Plants No. 1 and 2 were also cleaned and assessed to help identify and plan any necessary future rehabilitation projects. • Condition assessments on DAFT A and D at Plant No. 2 were completed during a scheduled project and maintenance shutdown. Severe corrosion was found on the moving mechanisms. The corroded mechanisms were fully coated through contracts with the on- call coating contractor, managed under the Asset Management Team. This approach avoided the need for equipment replacement, resulting in significant cost savings. The team plans to complete work on DAFT B and C next year. • Condition assessments of Trickling Filter Clarifiers B and D at Plant No. 2 were completed following planned preventive maintenance work. Broken parts and structural damage were identified on the clarifier mechanisms and walkways. The damage was repaired through Maintenance Projects with support from the on-call structural engineer. Following the clarifier assessments, the downstream RSS Pump Station B was also assessed to evaluate pump damage, plan overhauls, and prepare for spare pump procurement. The team will continue work to complete the remaining four clarifiers. • A condition assessment of the dewatering odor control biofilters at Plant No. 2 was completed and found the media plugged and in need of replacement. A media replacement project has been prepared to restore proper system function. • A condition assessment of the force mains at the Slater Pump Station, which was constructed in 1998, was conducted in August 2025 and found corrosion and coating failure from a visual inspection within the pipes, confirming the aging condition of the force mains. The pump station and force mains are set to be rehabilitated under Project 11-34, with construction to be completed in 2033. 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 some severe operational and structural defects that are isolated from current and future projects. 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 indicate a higher likelihood of failure because they are precursors to structural deformation and eventual collapse. Rather than create only Small Projects to address current and future isolated and severe asset issues, cost-effective and proactive maintenance-based approaches are being evaluated as follows: 2025 Asset Management Plan 130 • 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. • 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 because 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 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 create a new blanket contract for cleaning and sonar inspection of inverted siphons and large-diameter pipelines. The work includes pre-cleaning and post-cleaning sonar inspections to validate the effectiveness of each cleaning. NTP is expected to be issued in early 2026. 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 in the future. 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 will foster a more cost-effective CIP program while also reducing the risk of failures from unknown conditions. 3.4.2.2 Improving Collections Asset Management Workflow with Info360 Asset OC San contracted with Autodesk in 2023 to upgrade its asset management software for gravity sewers from Info Asset Planner to Info360 Asset (Info360). Autodesk imported available CCTV inspection data and geographic information system (GIS) datasets into Info360 Asset and created basic templates for risk modeling and decision trees. After the implementation project was completed in 2024, OC San imported video and images associated with each historical inspection to further centralize CCTV data. With the risk modeling features, OC San updated its Likelihood of Failure (LoF) model to balance incidence and severity of defects found during inspections, as well as incorporate soil class spatial data. A new LoF to RUL model was also created in the software by updating the mathematical model to revise RUL grade boundaries and creating a decision tree in Info360. Additionally, using the additional GIS spatial data for major transportation corridors, public buildings, OC San facilities, stormwater infrastructure, waterways, and pipeline diameter, a draft Consequence of Failure model was created to enable risk modeling with the software. Lastly, a preliminary calibration was performed for gravity sewer assets by performing multiple risk model runs with different risk calculation methods, formulas, and weights applied. 2025 Asset Management Plan 131 In 2025, OC San began to use the results of Info360 LoF to RUL and risk models to update RUL scoring for gravity sewer assets with new inspections. The improved asset management workflow consists of the following steps: • CCTV contractor uploads new NASSCO standard exchange database, videos, and images into Info360 Asset for review. • PDF reports are provided separately via OneDrive. Since these reports contain the same information as the digital reports in Info360 Asset, they do not need to be imported. • OC San reviews and approves submittals in Info360 Asset. Errors in submittals are returned to the CCTV contractor for correction prior to approval. • OC San re-runs risk model and RUL decision tree model. The risk model results directly feed into the RUL decision tree. • OC San exports RUL decision tree results and compares them with scoring in the Asset Registry. Any discrepancies in RUL scoring require additional engineering review to resolve. • To prioritize projects with equivalent RULs, OC San exports risk model results and applies the corresponding risk scores to assets within projects. These scores are then used to prioritize and rank projects and to update the AMP. 3.4.2.3 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. Project FRC-0017 is currently going out to bid and will be replacing various valves at Slater Pump Station. 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 15th 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.). Consequently, 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 2025, the Asset Management Team worked with Collections and contractors to plan and perform the inspection of force mains at Slater Pump Station. Force main inspections at 15th Street and College Pump Stations are planned for the upcoming 2026 year. The Asset Management Team will take lessons learned from the recent inspections to continue 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: 2025 Asset Management Plan 132 • Several of OC San’s 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, FE24-11, FR1-0011, and MPC-004 are in construction, and future CIP projects will replace obsolete VFDs at various locations at Plant Nos. 1 and 2 and the pump stations. • MP1-003, WSSPS Pump Replacement at Plant No. 1, currently in commissioning phase, replaced pump no. 5 with a chopper pump to alleviate ragging and grit issues that Maintenance has been facing at this pump station during the last few years. Once the pump is up and running, it will be tested and observed for 6 to 9 months. If deemed successful, the two remaining pumps will be replaced with chopper pumps as well via a separate project. • Main Sewage Pump No. 4 (MSP-4) at Plant No. 1, originally installed in 1988, has been in operation for nearly 40 years and is approaching the end of its useful life. The pump is scheduled to be replaced by CIP Project P1-105, currently in construction, within the next couple of years. During the 2024 dry season, it was removed and reinstalled to facilitate ongoing construction work in the headworks area, including the rehabilitation of the intake and discharge piping. Following its reinstallation, the pump has experienced increased vibration and bearing issues, necessitating its replacement with an available warehouse spare. The pump replacement is currently in progress and is contingent upon the completion of the intake pipe flange repair under P1-105. • Project PS22-02, On-site Oxygen Generation Feasibility Study at Plant No. 2, was completed in 2024 to evaluate whether an on-site 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, P2-142 Oxygen Gas Generation Facility at Plant No. 2 was developed to install a safe and reliable on-site oxygen generation system. • The A-Side Primary Clarifiers at Plant No. 2, 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 is in progress. • 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. • MP2-018 is currently in progress to provide needed repairs and replacement of parts on the spare main sewage pump and MSP-1. A future similar project will be initiated after the completion of MP2-018 for MSP-5 and MSP-6. MSP-7 is currently being repaired under a Maintenance work order. • MP2-023 is currently in construction to replace the circular drive equipment for Primary Clarifier N at Plant No. 2. Maintenance reported abnormal noise produced by the drive previously, and Asset Management developed a scope to remove and replace the obsolete drive with input and support from the OEM. • 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 2025 Asset Management Plan 133 compressed digester gas is delivered to the CenGen engines for reliable energy production. These dryers, located downstream of the digester gas compressors, are essential for lowering the dew point and removing moisture from the gas. As a critical part of the overall gas handling system, they play a key role in the reliable operation of both the Interplant gas pipeline and the engine systems. Construction of FE23-01 began in FY 2024–2025. Following the completion of FE23-01 construction and the design phase of J- 124 Digester Gas Facilities Rehabilitation Project, the design of Project FE24-02 design will begin. Project FE24-02 will focus on the replacing the chilled water heat exchanger and moisture separator at Plant No. 1 as well as upgrading the instrumentation on the gas dryer skids and the digester gas headers at both plants. These upgrades are planned to take place after the successful completion of FE23-01 and J-124, ensuring proper sequencing and seamless integration of the new systems into plant operations and maintaining continuous, reliable performance. • 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 an overhaul of Pump #4 in November 2022. MP2-0010 is in progress to overhaul the remaining three pumps. The overhaul of Pump #3, including discharge pipe replacement and additional repair work on Pump #4, was completed in 2025. The remaining work on Pumps #1 and #2 will be completed over the next 2 years. • MP2-015, Centrifuge Dewatering Lubrication Ring Pump Replacement at Plant No. 2, was developed as a solution to replace the unreliable and hard-to-obtain pump parts, and the project has moved forward into the construction phase and skid replacement. This is a critical function that provides lubrication water to reduce pressure in the high-pressure biosolids cake conveyance pipe from the centrifuge dewatering process to the cake storage silos. • Two Maintenance Projects were completed to coat the corroded DAFT A and D moving mechanisms at Plant No. 2. • MP2-031, Trickling Filter Clarifier B Repair at Plant No. 2, was completed to address structural damage to the clarifier mechanism and included replacement of some broken parts found from the condition assessment. • FE23-04 was completed to replace the truck loading scales at Plant No. 2. This critical project began as a maintenance effort to replace the severely corroded scales, which had reached the end of their useful life after 25 years in service. • Central Generation Facility Planning: The internal combustion engines at Plant No. 1 and Plant No. 2 have accumulated significant operating hours and require major overhauls to ensure reliable performance over the next decade or longer. Project J-135B successfully completed comprehensive top-to-bottom overhauls of Engines No. 1 and No. 3 at Plant No. 1, as well as Engines No. 1 and No. 5 at Plant No. 2. The project will continue its work to complete the overhaul of Engine No. 4 at Plant No. 2. Following this, Project J-135C will begin and, over the next 4 years, will complete the overhaul of the remaining engine generator set at Plant No. 1 and the two remaining engine generator sets at Plant No. 2. According to Planning Study PS20-04, completed in 2023, OC San’s current engines can be reliably maintained for at least the next 10 years with these overhauls and proper ongoing maintenance. • Energy and Digester Gas Master Plan (EMP): From 2022 to 2024, EMP PS21-04 evaluated options for energy production and digester gas management, considering emerging technologies, market trends, and permitting challenges. The study recommends continuing to operate the CenGen facilities and interplant pipeline until they reach the end of their useful life or market conditions drive replacement. Instead of a single solution, the EMP provides a 5- to 10-year roadmap for eventual replacement and includes future planning updates, recommending the plan be reviewed and updated in about 5 years to reflect evolving energy and regulatory conditions. In addition, multiple projects are 2025 Asset Management Plan 134 planned to upgrade and modernize support systems to ensure continued safe and reliable operation of the facilities during this transition period. • PS21-07 CenGen Digital Twin Project: OC San launched Project PS21-07 to model the CenGen systems at Plant No. 1 and Plant No. 2 using digital twin technology integrated with the APRICOT™ platform. These models support operations, maintenance, troubleshooting, and process optimization. The project focused on developing digital twins to analyze system performance, detect anomalies, and assess the long-term use of anomaly detection tools. Given the plants’ 30+ years of operation, the study team collected design documents, site data, and historical records to model key units, using loop-based energy balance calculations where data was limited. Completed in May 2025, the study provided recommendations to improve current systems and represented an early milestone in the District’s use of artificial intelligence for smarter, data-driven plant management, while acknowledging that many steps will still be needed to further optimize performance and integrate advanced technologies. • Various cable replacement maintenance projects were executed to address failed power cables feeding critical equipment. These include MP1-011 for Main Sewage Pump No. 2 and MP1-016 for Gas Compressor No. 1 at Plant 1, and MP2-025 for Solids Contact Blower No. 2 at Plant 2. 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 (PS23-04). 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 (BI) dashboards. • Enhance collaboration and data sharing between the Maintenance and Engineering teams to support both short-term and long-term planning through 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 developing 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 short-term and long-term, how the new Digital Asset Management Study will address many of these improvement opportunities, and their status. 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. 2025 Asset Management Plan 135 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 less 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. STATUS: In progress via Digital Asset Management Study. Data-Driven Asset Management: • Develop asset management BI dashboards to track maintenance KPIs and key major asset information, including RULs and future project planning. STATUS: In progress via Digital Asset Management Study. • Use BI dashboard algorithms to more accurately estimate asset performance and RUL. STATUS: Future goal after completion of Digital Asset Management Study. • Optimize CIP planning using BI cost and risk modeling and constraints. STATUS: Future goal after completion of Digital Asset Management Study. Risk Assessment (Likelihood and Consequence of Failure): • Identify a risk assessment approach and develop a framework that fits OC San’s needs. STATUS: In progress via Digital Asset Management Study. • Use risk assessment modeling and scoring to better prioritize projects. STATUS: Future goal after completion of Digital Asset Management Study. These improvement opportunities will be evaluated and updated in the annual AMP. 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 2025 Asset Management Plan 137 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 2025–2026 Budget Update, updated in June 2025, 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 2025–2026 CIP Outlay is $289.0 million and is further divided into process categories, as shown on Figure 4-2. Liquid Treatment, Collection Facilities, and Other are the primary areas where the FY 2025–2026 CIP outlay will be spent. For liquid treatment, Project P1-105, Headworks Rehabilitation at Plant No. 1, and Project P2- 98, Primary Treatment Rehabilitation at Plant No. 2, are expected to be the largest expenditures of $24 million and $23 million, respectively, in FY 2025–2026. For Other, equipment purchases are expected to be the largest expenditures of $59 million in FY 2025–2026. Lastly, for collection facilities, Project 3-67, Seal Beach Pump Station Replacement, Project 5-67, Bay Bridge Pump Station Replacement, and Project 11-33, Edinger Pump Station Replacement, comprise nearly 40% of collections CIP spending at a combined expenditure of $25 million. Figure 4-1. 20-Year CIP Outlay 2025 Asset Management Plan 138 Figure 4-2. FY 2025–2026 CIP Outlay by Process – $289.0 Million 4.2 Maintenance Expenditures 4.2.1 Five-Year Historical Maintenance Expenditures Figure 4-3 and Figure 4-4 show the historical actual 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, and 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 2025 Asset Management Plan 139 Figure 4-3. Five-Year Historical Maintenance Costs for Treatment Plants Figure 4-4. Five-Year Historical Maintenance Costs for Collection System 2025 Asset Management Plan 140 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 August 1, 2025, 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. 2025 Asset Management Plan 141 Table 4-1.

FROM:Robert Thompson, General Manager Originator: Riaz Moinuddin, Director of Operations & Maintenance SUBJECT: SONAR INSPECTIONS &PIPELINE CLEANINGS OF INVERTED SIPHONS AND LARGE DIAMETER PIPELINES, SPECIFICATION NO. S-2025-695BD GENERAL MANAGER'S RECOMMENDATION RECOMMENDATION: A. Approve a General Services Contract to Performance Pipeline Technologies, Inc. (PPT) dba Sanitation Systems for Sonar Inspections & Pipeline Cleanings of Inverted Siphons and Large Diameter Pipelines, Specification No. S-2025-695BD, for a total amount not to exceed $1,750,000 for the period of January 1, 2026, through December 31, 2026; with four (4) optional one-year renewal options; and B. Approve an annual contingency of $175,000 (10%). BACKGROUND Orange County Sanitation District (OC San)maintains more than 350 miles of gravity sewer pipes in its service area which are cleaned on a scheduled basis consistent with OC San’s Sewer System Management Plan (SSMP).Line segments range in size from 8 inches to 120 inches.Depending on the pipe size and historical issues,cleaning frequencies have been developed and range from every 4 weeks to once every 5 years. For smaller diameter pipes ranging from 8 inches to 18 inches,cleaning is conducted primarily through hydraulic flushing and vacuuming using a combination sewer cleaning vehicle.For medium diameter pipes ranging from 21 inches to 42 inches,pipes are cleaned mechanically using a cable tethered tire to act as a moving hydraulic scouring plug.Pipes greater than 42 inches are generally designed to be “self-cleaning”by creating internal flow velocities that scour potential sediment and are not regularly cleaned by OC San and are typically assumed to be self-cleaning by design of proper scouring velocity. The purpose of this General Services Contract is to perform sonar inspections and pipeline cleanings of inverted siphons and large diameter pipelines within OC San’s wastewater collection system where self-cleaning flows are not occurring.The contract provides for both pre and post-cleaning sonar inspections,pipeline debris removal and disposal,and data reporting in high-resolution sonar imagery formats.These activities enable OC San to identify structural defects,quantify sediment Orange County Sanitation District Printed on 12/8/2025Page 1 of 4 powered by Legistar™ File #:2025-4642 Agenda Date:12/17/2025 Agenda Item No:8. accumulation, and optimize cleaning frequency for critical assets. RELEVANT STANDARDS ·Protect OC San assets ·24/7/365 treatment plant reliability ·Maintain a proactive asset management program PROBLEM Sonar assessments conducted in recent years have identified increased debris accumulation and sediment buildup in several major large diameter pipes,trunk sewers and inverted siphons.These conditions can reduce hydraulic capacity,cause operational inefficiencies,and elevate the risk of sanitary sewer overflows (SSOs).Existing internal cleaning resources are not sufficient to perform the large-diameter inspections required to maintain system performance and regulatory compliance. PROPOSED SOLUTION Establish a General Services Contract to provide specialized large-diameter and inverted siphon cleaning and sonar inspection services on both an as-needed and scheduled basis.This contract will enable OC San to proactively identify problem areas and maintain optimal pipeline capacity. TIMING CONCERNS N/A RAMIFICATIONS OF NOT TAKING ACTION Failure to perform these inspections and cleanings could result in debris accumulation,reduced flow capacity,and potential SSOs.These issues could increase emergency maintenance costs,negatively affect treatment performance, and potentially lead to regulatory violations. PRIOR COMMITTEE/BOARD ACTIONS N/A ADDITIONAL INFORMATION A Request for Proposal (RFP)was issued on September 4,2025,and proposals were received on October 6, 2025.

FROM:Robert Thompson, General Manager Originator: Mike Dorman, Director of Engineering SUBJECT: SUPPLEMENTAL ENGINEERING SERVICES, CONTRACT NO. PSA2021-002 GENERAL MANAGER'S RECOMMENDATION RECOMMENDATION: Authorize the General Manager to transfer funds between existing Professional Services Agreements to provide Supplemental Engineering Services,Contract No.PSA2021-002,with Jacobs Project Management Co.and AECOM Technical Services,Inc.,to balance contract budgets through April 2027,with no increase to the total Board authorized not to exceed amount of $29,700,000 per agreement. BACKGROUND To ensure that projects are completed on time and each properly controlled,the Orange County Sanitation District (OC San)has utilized Supplemental Engineering Services (SES)to augment staff resources.In April 2022,the Board approved SES agreements to both Jacobs Project Management Co.(Jacobs)and AECOM Technical Services,Inc.,(AECOM)for a three-year period with two one- year renewal options (May 1, 2022 - April 30, 2027), each for an amount not to exceed $29,700,000. With the additional staffing plan approved by the Board in November 2025,OC San will continue to rely on SES agreements to meet the demands of the expanding Capital Improvement Program (CIP) workload.To ensure a smooth transition between contracts,a new Request for Proposals (RFP)for SES services will be issued in January 2026,allowing for a nine-month overlap with the existing agreements.The staffing levels in the upcoming RFP will reflect the Board-approved additional staffing plan. RELEVANT STANDARDS ·Comply with California Government Code Section 4526 to engage the best qualified firm “on the basis of demonstrated competence and qualifications” and “negotiate fair and reasonable fees” ·Ensure the public’s money is wisely spent. ·Sustain 1, 5, and 20-year planning horizons Orange County Sanitation District Printed on 12/8/2025Page 1 of 3 powered by Legistar™ File #:2025-4643 Agenda Date:12/17/2025 Agenda Item No:9. PROBLEM When the SES contract started,OC San issued staffing requests and task orders to both firms. AECOM took a few years to ramp up and provide their share of staffing,resulting in an imbalance in spending between the two firms.Jacobs is providing a significantly larger number of SES staff than AECOM,causing their contract funds to be expended at a faster rate.Currently,Jacobs provides 44 full-time staff,compared to 10.5 staff provided by AECOM,a utilization rate roughly four times greater.As a result,Jacobs’budget is projected to be depleted by February 2026,approximately 15 months before the end of the current contract term on April 30, 2027. PROPOSED SOLUTION Authorize the General Manager to transfer funds between existing SES agreements to maintain staffing continuity and ensure smooth completion or transition of current assignments during the overlap between existing and future SES contracts. TIMING CONCERNS If the Jacobs contract runs out of funds before the new SES contracts are executed,projects may be delayed if AECOM cannot fill these roles with their staff.This could also reduce project delivery efficiency. RAMIFICATIONS OF NOT TAKING ACTION Jacobs will run out of funds before the end of the contract. PRIOR COMMITTEE/BOARD ACTIONS April 2022 -Approved Professional Services Agreements to provide Supplemental Engineering Services,Contract No.PSA2021-002,for a three-year period commencing May 1,2022,through April 30,2025,with two one-year renewal options,for an amount not to exceed $29,700,000 per individual agreement with the following two firms:AECOM Technical Services,Inc.and Jacobs Project Management Co.

FROM:Robert Thompson, General Manager Originator: Mike Dorman, Director of Engineering SUBJECT: SANTA ANA TRUNK SEWER REHABILITATION, PROJECT NO. 1-23 GENERAL MANAGER'S RECOMMENDATION RECOMMENDATION: Approve an Agreement for Purchase and Sale and Joint Escrow Instructions with C.J.Segerstrom & Sons (“Segerstrom”)that defines the terms and conditions for temporary construction easements in the amount of $509,300 for Santa Ana Trunk Sewer Rehabilitation,Project No.1-23,and disbursement of severance damages from an escrow holding account with an upper limit amount of $1,009,270 for potential adverse impacts during construction. BACKGROUND The Santa Ana Trunk Sewer carries sewage from the southern portion of the cities of Santa Ana and Costa Mesa to the Orange County Sanitation District (OC San)Plant No.1.This sewer was originally constructed in the early 1950s and consists of unlined 42-inch,and 48-inch diameter reinforced concrete pipe.Over the past 70 years,several projects have replaced or rehabilitated small portions of the sewer and rehabilitated most of the manholes. The existing Santa Ana Trunk Sewer is located in permanent easements and public right-of-way.The Segerstrom properties comprise a business park with multiple office,commercial,and industrial buildings.OC San has negotiated temporary construction easements for a duration of 36 months and parking spaces for a duration of 9 months with Segerstrom to perform the construction activities. Construction activities within the subject properties include the construction of a new 84-inch diameter manhole,rehabilitation of two existing manholes,installation of approximately 1,840 linear feet of 48-inch diameter cured-in-place pipe (CIPP),routing of approximately 3,500 linear feet of temporary bypass piping, and operation of temporary bypass pumping equipment. RELEVANT STANDARDS ·Protect OC San assets ·Maintain collaborative and cooperative relationships with regulators, stakeholders, and neighboring communities Orange County Sanitation District Printed on 12/8/2025Page 1 of 3 powered by Legistar™ File #:2025-4644 Agenda Date:12/17/2025 Agenda Item No:10. ·Maintain a culture of improving efficiency to reduce the cost to provide the current services level or standard PROBLEM Temporary construction easements are needed from Segerstrom to execute the project.Due to concerns that the construction work and bypass operation may negatively impact Segerstrom tenants and business operations,Segerstrom seeks an agreement providing compensation in the event construction activities result in non-renewal of six tenants,inability to lease two vacant spaces,and an increased duration in the use of parking spaces in the event the construction takes longer than 9 months. PROPOSED SOLUTION Approve an agreement with Segerstrom defining the terms and conditions for temporary construction easements and the disbursement of severance damages.The terms and conditions of the escrow for the severance damages include a checklist defining the requirements that need to be achieved before disbursement is performed.All unused or excess funds remaining in escrow will be returned to OC San. TIMING CONCERNS Construction is scheduled to begin in January 2026.Access to the Segerstrom properties will be needed shortly after notice to proceed. RAMIFICATIONS OF NOT TAKING ACTION Without this severance agreement,Segerstrom will not provide the temporary construction easements and rehabilitation of the Santa Ana Trunk Sewer will not be able to be performed. PRIOR COMMITTEE/BOARD ACTIONS November 2025 -Awarded a Construction Contract Agreement to Steve P.Rados,Inc.,for Santa Ana Trunk Sewer Rehabilitation,Project No.1-23,for a total amount not to exceed $44,787,000 and approved a contingency of $4,478,700 (10%). ADDITIONAL INFORMATION N/A CEQA The project is exempt from CEQA under Class 1 and 3 categorical exemptions set forth in California Code of Regulations Sections 15301 and 15303.A Notice of Exemption was filed with the OC Clerk- Recorder on April 29, 2022.

It is a condition precedent to the Closing for Buyer’s benefit that Buyer has determined that the TCE is suitable for Buyer’s intended use, as determined by Buyer in its sole discretion. Prior to the Closing Date, Buyer shall determine whether the Temporary Construction Easement Areas are suitable and shall provide to Seller and Escrow Holder its written notice of such determination; provided, however, that any failure of Buyer to provide notice shall be deemed approval; and, in connection with any disapproval, Buyer may, but need not, include its election to extend the Closing Date as provided in Section 8.6 below. In the event Buyer determines that the TCE is suitable, such determination by Buyer shall not alter or diminish Seller’s covenants, agreements, representations and/or warranties made herein or under law, unless a representation or warranty is expressly and specifically waived in writing in whole or in part by Buyer. In the event Buyer determines that the Temporary Construction Easement Areas are not suitable, then Buyer may terminate this Agreement as provided in Section 6.1 below. 4.2 Inspections, Testing and Right of Entry. Prior to Closing, Buyer may conduct, at Buyer’s sole expense, such inspections and testing of the Temporary Construction Easement Areas, including, without limitation, any improvements thereon, as Buyer may desire or deem appropriate, in Buyer’s reasonable discretion, to determine the suitability of the Temporary Construction Easement Areas for Buyer’s intended use. In conducting such inspections and testing, Buyer shall endeavor to minimize, and shall be responsible for, damage to the Temporary - 10 - 109464\18502580v7 Construction Easement Areas, as well as any improvements thereon, and shall, in the event the Closing fails to occur for any reason other than Seller’s default under this Agreement, return the Temporary Construction Easement Areas, including any improvements thereon, to their condition prior to the inspections and testing, except that Buyer shall have no responsibility or liability for returning the Temporary Construction Easement Areas to its prior condition to the extent that any change or modification resulted from (i) reasonable wear and tear, (ii) force majeure or (iii) any other cause not within the reasonable control of Buyer or any Buyer Parties, including, without limitation, the acts or omissions of any person or entity other than Buyer and/or Buyer Parties. Seller hereby grants to Buyer and its representatives permission and a license to enter upon the Temporary Construction Easement Areas at all reasonable times prior to the Closing Date for the purpose of conducting such inspections and testing; provided that Buyer provides Seller with not less than five (5) calendar days prior written notice of the specific areas of the Temporary Construction Easement Areas that Buyer is requesting access to, and Seller consents to such access in writing.

In order to avoid an upfront payment by Buyer for potential Severance Damages, and in order to protect the Seller from realized Severance Damages, the Parties desire to establish the Severance Escrow, tender the Severance Damage Fund to the Severance Escrow, and cause distribution of Severance Payments to the Seller in the manner described herein. The Parties shall execute such further documentation as may be required to facilitate the intent of this Exhibit 7, including any further agreement with the Severance Escrow to establish the Severance Escrow, fund the Severance Damage Fund, and permit timely disbursement of Severance Payments to Seller. 2. Potentially Impacted Tenants. Seller’s right to Severance Payments shall apply to the Severance Damages related to the following Seller tenants (including their lawful successors and assigns to their leasehold interests under the tenant’s lease with Seller) and properties: This document sets forth the procedures to be followed for disbursement of Severance Payments to Seller in the event of Severance Damage in connection with one of the above tenants or properties. 3. Severance Escrow Holding. Buyer shall deposit into the separate Severance Escrow the Severance Damage Fund amount of ONE MILLION NINE THOUSAND TWO HUNDRED SEVENTY DOLLARS ($1,009,270). This amount has been calculated as the aggregate of potential Severance Damages applicable to the above tenants. - 3 - 109464\18502580v7 4. Seller’s Severance Payment Draw Request. a. In the event the Seller incurs Severance Damages applicable to one or more of the above tenants or properties, Seller shall issue a Severance Payment draw request (“Severance Payment Draw Request”) to the Severance Escrow and Buyer. b. The Severance Payment Draw Request shall include reasonable evidence that the Buyer’s Project or other acts or omission on or adjacent to the Property, contributed to the tenant(s) terminating its lease or electing not to renew its lease at the fair market value of the applicable leased portion of the Property (which fair market value determination shall not include any depreciated or reduced value arising out of the Project or Buyer’s access to or use of the applicable Property or adjacent areas) (“Evidence of Impact”). The Severance Payment Draw Request shall include a reasonable description of the amount requested. c. In the event Seller’s tenant submits a written acknowledgement that the Project or Buyer’s involvement at or near the Property site was a substantial contributing factor to the tenant’s termination or non-renewal of the lease, such acknowledgement shall satisfy the Seller’s obligation to provide Evidence of Impact. d. Buyer shall have ten (10) business days to object, in writing, to the Seller’s Severance Payment Draw Request, which objection shall include a written description of the specific basis for Buyer’s objection, and shall be submitted to Seller and Severance Escrow. Buyer’s failure to provide a written objection within such ten (10) business days shall be deemed as Buyer having no objection to the Severance Payment Draw Request. e. Severance Escrow shall release the amount of the Severance Payment included in Seller’s Severance Payment Draw Request to Seller within fifteen (15) business days of Severance Escrow’s receipt of such Severance Payment Draw Request, unless Severance Escrow receives Buyer’s timely objection, as described above. f. In the event Buyer timely objects to Seller’s Severance Payment Draw Request, the Parties shall meet and confer within five (5) business days and use good faith efforts to resolve the Buyer’s objection. Buyer and Seller shall provide notice to Severance Escrow of the resolution of the objection, and any revisions to the applicable Severance Payment Draw Request. g. Following receipt of such notice of resolution, Severance Escrow shall release the amount of the Severance Payment included in the revised Severance Payment Draw Request to Seller within ten (10) business days. 5. Opportunity to Mitigate. Nothing in this Exhibit 7 shall limit Buyer’s rights to mitigate the impact of the Project on tenants, as set forth in Exhibit 4, Section H, to the Agreement. - 1 - 109464\18502580v7 EXHIBIT 8 TO PURCHASE AND SALE AGREEMENT AND JOINT ESCROW INSTRUCTIONS List of Accepted Title Reports • Preliminary Title Report APN 415-051-04 by Commonwealth dated June 6, 2023.

Recommendation Questions? 6 5 6 OPERATIONS COMMITTEE Agenda Report Headquarters 18480 Bandilier Circle Fountain Valley, CA 92708 (714) 593-7433 File #:2025-4645 Agenda Date:12/17/2025 Agenda Item No:11. FROM:Robert Thompson, General Manager Originator: Mike Dorman, Director of Engineering SUBJECT: A-SIDE PRIMARY CLARIFIERS REPLACEMENT AT PLANT NO. 2, CONTRACT NO. P2-98A GENERAL MANAGER'S RECOMMENDATION RECOMMENDATION: Approve a contingency increase of $4,456,235 (4%)to the existing Construction Contract with PCL Construction,Inc.,for A-Side Primary Clarifiers Replacement at Plant No.2,Contract No.P2-98A as part of Primary Treatment Rehabilitation at Plant No.2,Project No.P2-98,for a new total contingency amount of $11,140,588 (10%). BACKGROUND Orange County Sanitation District’s (OC San)primary treatment process removes most of the solids from screened wastewater and is an essential part of the wastewater treatment process.This treatment is performed in large concrete structures called primary clarifiers. The primary treatment facilities at OC San’s Plant No.2 consist of fourteen 140-foot-diameter circular clarifiers built between 1960 and 1985,along with associated piping,distribution structures,sludge pumping,odor control,and power distribution systems.The clarifiers are divided into three groups: the A-Side,consisting of four clarifiers;and the B-Side and C-Side,consisting of five clarifiers each. The A-Side primary clarifiers were constructed between 1960 and 1963 and require complete replacement.The new A-Side primary clarifiers are being constructed in an area adjacent to the existing units in an older area of the Plant with poorly documented structures dating back to the 1950s. OC San executed the A-Side Primary Clarifiers Replacement Project,Contract No.P2-98A to construct four new primary clarifiers,a new odor control and chemical facility,a new electrical distribution center,and ancillary utilities and facilities.Once the new facilities are completed,the project will also demolish the four existing A-Side primary clarifiers,a power building,and an odor control facility. Construction began in July 2021,and is expected to be completed by late 2027.Construction is approximately 70% complete. Orange County Sanitation District Printed on 12/8/2025Page 1 of 3 powered by Legistar™ File #:2025-4645 Agenda Date:12/17/2025 Agenda Item No:11. RELEVANT STANDARDS ·Ensure the public’s money is wisely spent ·24/7/365 treatment plant reliability PROBLEM The cost of changes to the construction contract is nearing the Board-approved contingency amount. The changes to date have largely been related to unknown conditions and unanticipated changes. Examples of some of the larger changes include: (1)Additional demolition,disposal and removal of unforeseen and abandoned underground obstructions such as old pipelines,concrete structures and slabs,and electrical duct banks that interfered with construction. (2)Changes in soil improvement methods due to unknown buried structures and debris not shown in the original plans. (3)Added direct costs for construction delays caused by unforeseen conditions. (4)Added installation of a large stainless steel bulkhead to properly separate non-reclaimable wastewater flows as required by the GWRS system. (5)Added protective liner installation around the outside walls of each clarifier to prevent gas intrusion, concrete corrosion, and other clarifier liner failures. The current authorized contingency is insufficient to cover future changes for the remaining work. Additionally,there are several unresolved disputed items totaling approximately $11M.While OC San disputes the merit of these items,the problem-solving process with the contractor is still ongoing. As such, the final determination of merit and the potential for additional costs remains uncertain. PROPOSED SOLUTION Approve a contingency increase to cover future changes required to complete the remaining construction work. TIMING CONCERNS Additional contingency funds are required to approve any future construction changes without causing project delays.If problems arise,the construction work might have to be stopped until additional contract funds are authorized to resolve the issue.These delays could result in extended overhead and direct cost claims from the contractor. RAMIFICATIONS OF NOT TAKING ACTION Not increasing the construction contingency will prevent OC San from authorizing PCL Construction, Inc., to perform additional unanticipated work.

FROM:Robert Thompson, General Manager Originator: Wally Ritchie, Director of Finance SUBJECT: ORANGE COUNTY EMPLOYEES RETIREMENT SYSTEM PREPAYMENT GENERAL MANAGER'S RECOMMENDATION RECOMMENDATION: Approve prepayments of Orange County Employees Retirement System contributions in the amount of $10.3 million, using funds from OC San’s 115 Trust. BACKGROUND Orange County Employees Retirement System (OCERS)offers agencies the opportunity to participate in the Early Payment of Employer Contributions Program.This program allows agencies to prepay their annual OCERS contribution with a discount rate of 7%.OC San has participated in this program since 2010 to realize savings on contributions. In 2021,OC San implemented an Internal Revenue Service Code Section 115 Trust Pension Account (115 Trust)with Public Agency Retirement Services.The 115 Trust is established to fund pension obligations,once contributions are made into the trust,fund use is limited to pension costs.OC San’s future pension obligation to OCERS is fully funded as of June 30, 2025. The current balance in the OC San’s 115 Trust account is $18.3 million.The recommended OCERS Prepayment is $10.3 million, leaving a balance of 8.0 million in the 115 Trust account. RELEVANT STANDARDS ·Ensure the public’s money is wisely spent ·Ensure that investment proposals and decisions are based on clearly defined standards PROBLEM Funds in the 115 Trust can only be used to pay for pension obligations.

President Trump signed the bill to fund the government, bringing a close to the longest government shutdown in history. The passage of the CR represents a limited victory by reopening the federal government until January 30, 2026. Congress will have a little more than two months from the signing of the bill to reach agreement on full year, fiscal year (FY) 2026 spending bills that were not included in the CR, including spending bills that fund the U.S. Environmental Protection Agency (USEPA). It is important to note that the CR carries full year spending agreements for three of the twelve appropriations bills—Agriculture/U.S. Food and Drug Administration, Military Construction/Veterans Affairs, and Legislative Branch. Key Provisions of CR The CR passed the Senate 60-40 when seven Democrats and Senator Angus King (I- ME) joined Senate Republicans to provide the magic number of 60 votes to overcome a Democrat filibuster and the House approved the measure 222-202. The CR reopens and extends government operations through January 30. This means Congress must either pass a final CR for the remaining months of FY 2026 or secure an agreement on the outstanding nine spending bills before January 30 to avoid the potential of another shutdown. In this circumstance, an omnibus bill or a minibus (a package of several bills that have been reconciled) would likely carry the agreement through the House and Senate. 2 | P a g e The CR provides for continued funding of existing programs at FY 2025 levels until final spending bills are enacted. USEPA programs will be funded and presumably have the resources to finalize outstanding financial awards delayed by the shutdown. The CR contains increased funding for per- and polyfluoroalkyl substances (PFAS) cleanups at military installations and $9 million for USDA’s Center of Excellence for PFAS solutions that will likely continue to review PFAS impacts upon soils and cattle. Senate Committee to Examine PFAS Cleanup and Disposal Policy On November 19, the Senate Committee on Environment and Public Works held a hearing to examine future policy solutions to address PFAS cleanup and disposal. The hearing comes as Congress continues to try and develop policy that ensures parties responsible for PFAS contamination are held liable for cleanup and disposal costs and not those who passively receive the chemicals, like wastewater agencies. The hearing will include witnesses from Clean Harbors, a hazardous waste management services company, Associated General Contractors of America, and the Congressional Research Service. Importance to OC San While the hearing did not address Superfund liability exemption for passive receivers, it will keep pressure on lawmakers to create clear, practical protocols for managing PFAS as a hazardous substance and ensure cleanup policies are effective and enforceable. Based off of previous comments from the sectors represented by the witnesses, the discussion may highlight the unintended consequences USEPA’s 2024 Rule designating PFAS as a hazardous substances has created for cleanup and disposal of waste containing PFAS and the need for Congress to address these impacts statutorily.

Members are meeting with constituents, hosting local events, and preparing for the next legislative session, which begins January 5, 2026. Voters Pass Proposition 50 On November 4, 2025, California voters approved Proposition 50 in a statewide special election, with the measure receiving approximately 64 percent support. Counties have until December 5 to submit their certified vote counts to the Secretary of State, who is scheduled to certify the final election results on December 12. Federal Lawsuit Filed Over California’s Post-Proposition 50 Redistricting Plan On November 13, the US Department of Justice (DOJ) announced they filed a lawsuit seeking to block California’s newly approved congressional district map, which was adopted under Proposition 50 for use in the 2026–2030 election cycles. The measure shifts responsibility for drawing congressional districts from the state’s independent redistricting commission to the Legislature, resulting in a redesigned map that could alter the political balance in several districts. The DOJ’s complaint argues that the map relied heavily on racial demographics, particularly the distribution of Hispanic voters, in ways that may violate the Equal Protection Clause and the Voting Rights Act. The lawsuit follows a separate challenge brought by the state’s Republican Party, which has also raised concerns about how the districts were drawn. The case introduces both legal and political uncertainties. Legally, it tests the boundary between permissible political considerations in redistricting and the constitutional limits on using race in the process. Politically, the outcome may influence competitive dynamics in upcoming congressional elections and shape how states approach redistricting in future cycles. Statewide Initiative Proposes Streamlined Project Review The California Chamber of Commerce recently submitted a proposed statewide initiative to the Attorney General’s Office seeking to modernize California’s environmental review process for major projects. The proposal, titled the Building an Affordable California Act, is designed to streamline approvals for “essential projects” such as housing, infrastructure, and public-service facilities, with the goal of improving affordability and reducing project delays. 2 The measure would establish defined timelines—generally up to one year—for state and local agencies to complete environmental reviews and issue final decisions on qualifying “essential projects,” including housing, renewable energy facilities, water and sanitation, broadband infrastructure, public health projects, municipal first responder facilities, and transportation improvements. If agencies fail to meet the proposed deadlines, applicants could request public hearings, and any legal challenges would be subject to expedited judicial review. Beyond addressing permitting delays, the initiative seeks to lower project costs, create jobs in construction and clean energy sectors, and advance infrastructure investments that promote housing affordability and economic growth. It also includes provisions ensuring that, if enacted, the measure will be legally defended on behalf of voters. If certified, the Building an Affordable California Act could appear on the 2026 statewide ballot, where voters would decide whether to adopt these proposed changes to California’s environmental and project approval framework. Delta Conveyance Project Update Governor Newsom and the California Department of Water Resources (DWR) announced two key milestones advancing the Delta Conveyance Project, a major water infrastructure effort intended to strengthen the State’s water supply and climate resilience. DWR submitted a certification of consistency to the Delta Stewardship Council, stating that the project complies with the Delta Reform Act and the State’s Delta Plan, which aim to balance environmental protection in the Sacramento–San Joaquin Delta with the need for a reliable water supply. In addition, the Third District Court of Appeal lifted a previous injunction, allowing DWR to resume pre-construction geotechnical work, including soil testing and subsurface investigations critical to project planning and design. Governor Newsom highlighted these developments as part of the Administration’s broader strategy to modernize California’s water infrastructure and prepare for the challenges of a changing climate. State officials emphasized that these steps are necessary to ensure long-term water reliability for millions of residents, while continuing to safeguard the Delta ecosystem and address the impacts of drought, flooding, and aging water systems. 1 | P a g e TO: Orange County Sanitation District FROM: Whittingham Public Affairs Advisors DATE: November 21, 2025 SUBJECT: Local Legislative Report Following are a few of the more notable developments and issues that have transpired in Orange County over the last several weeks: • The Cypress City Council held a special meeting on November 19 to interview seven finalists for potential appointment to replace former Council member Scott Minikus, who resigned from City Council October 1. • Multiple cities countywide continue to experience leadership changes. The Irvine City Council officially named Interim City Manager Sean Crumby as its new City Manager, while Cecilia Gallardo-Daly continues to serve as Interim City Manager in Costa Mesa. Looking forward, Newport Beach Assistant City Manager Seimone Jurjis will step into the City Manager role on January 1, 2026, succeeding Grace Leung, and Dana Point City Manager Mike Killebrew announced that he will be retiring as well at the end of the year. • Final negotiations are ongoing between the County of Orange and a coalition of cities and sanitation districts regarding landfill tipping fees, known as the Waste Infrastructure System Enhancements (WISE) agreements. Upon final approval by the Board of Supervisors (currently scheduled for December 2), each jurisdiction will work to complete their respective Prop 218 hearings and approve the rate increases prior to the new fees going into effect July 1, 2026. • The Anaheim City Council voted unanimously to increase sewer impact fees for new development in the Anaheim Hills area. The Council recently rejected a proposal to establish a 3 percent gate fee on various tourism destinations in the city, choosing instead to consider generating revenue from established sources. Per the staff report, the current sewer fee for a single-family home is $491; under the increase, the fee for a new single family home will be $667. 2 | P a g e • The South Coast Water District (SCWD’s) Board of Directors unanimously approved a Memorandum of Understanding (MOU) regarding a potential public agency to public agency partnership, wherein Orange County Waste & Recycling (OCWR) would generate renewable energy from the Prima Deshecha Landfill and provide it as a long-term power supply for SCWD’s Doheny Ocean Desalination Project. Prior to consideration of the MOU, a task force was formed between the staff of both agencies in 2022 and a corresponding report, entitled Assessment of Joint Opportunities to Benefit South Orange County Through Renewable Energy and Local Water Supply, was finalized in September 2025. The draft MOU was subsequently approved by the Board of Supervisors, and OCWR is also in discussions with other South County agencies about a similar partnership. • The Board of Supervisors also approved new rules that will enable Sheriff’s deputies to remove homeless encampments from County-owned property, including parks and flood control channels. Santa Ana, Anaheim, Irvine, Garden Grove, and Fullerton are among the cities that previously approved similar rules in the wake of the U.S. Supreme Court’s 2024 decision that enabled local jurisdictions to take such actions. As part of our scope of work, Whittingham Public Affairs Advisors has continued to monitor the various City Council agendas and highlighted issues and items of relevance to OC San. We also continue to monitor activities at the South Coast Air Quality Management District, Orange County Water District, and South Orange County Wastewater Authority. It is a pleasure to work with you and to represent the Orange County Sanitation District.

The PAO's main goal is to ensure messages are accurate, transparent, and build public trust and confidence. An integrated Public Affairs Strategic Plan is essential for effectively addressing the diverse audiences we serve. The PAO offers services, tools, and programs to meet OC San’s communication needs. This includes media relations, website and intranet site content, construction outreach, elected officials and government relations, internal communications, education, outreach, and graphic development. The PAO has developed a Strategic Plan (Plan) for Fiscal Years 2024 - 2026. This Plan is developed based upon the principles of OC San’s Mission of protecting public health and the environment and will support the implementation of OC San’s Strategic Plan. This Plan offers a vision to unify our communication efforts and focus resources to achieve the greatest impact and greatest results. Because much of what is planned and created by this group is based on external factors and therefore outside of our control, flexibility and fluidity is integrated into the Plan. The PAO will follow the guidance set forth by management and the Board of Directors to carry out OC San’s messaging and support our member agencies. Background Information OC San represents 20 cities, 4 special districts, and a portion of the unincorporated County of Orange. This area represents a community of 2.6 million people with approximately 550,000 customer accounts. Unlike most public agencies where there is direct contact with customers, OC San’s billing occurs through the County of Orange property tax bills. Therefore, OC San must work through other means to communicate with the public and the rate payers. We have a 25-member Board of Directors, and more than 650 employees within six departments with various goals and objectives. While these groups work independently on a variety of projects, the goal of the PAO is to provide support and messaging that is consistent throughout the agency so that we are one voice, representing the same overall goals, and portraying the same brand. PAO Strategic Plan FY 2024-26 June 2024 2 There are many challenges with serving such a large and diverse customer base, however; there are also great opportunities working through the strategies laid out in this Plan. Public Affairs Team The division is staffed with seven full-time employees and overseen by a supervisor and a department head. Jennifer Cabral, Director of Communications Daisy Covarrubias, Public Affairs Supervisor Rebecca Long, Senior Public Affairs Specialist Belen Carrillo, Senior Public Affairs Specialist Kelly Newell, Public Affairs Specialist Public Affairs Specialist – Vacant Gregg Deterding, Graphics Designer Isai Carrillo, Graphics Designer Cheryl Scott, Administrative Assistant Each of these team members carry out specific functions to meet the communication goals and objectives laid out in this Plan. Situation Analysis • OC San approved a five-year rate program in 2023. Public communication must account for the financial impact on OC San ratepayers as decisions and proposed fees for the next five years are developed and communicated. • OC San must continue to attract talented and qualified personnel to fill vacancies. Effectively communicating OC San’s culture and emphasizing the importance of professional relationships is essential to the effectiveness and functionality of the agency. • OC San will have new Board leadership and is anticipating a high turnover post the November 2024 election. Continuous engagement with the Board of Directors will be critical for the success of this agency. PAO Strategic Plan FY 2024-26 June 2024 3 • As an essential service, OC San has continued to execute the Capital Improvement Program (CIP) to keep the regional projects on schedule, improving and maintaining the regional sewer system throughout the service area. In the next two fiscal years, OC San plans to award 38 construction contracts worth a total of $340 million. • OC San administrative staff have moved into a new Headquarters across the street from Plant No. 1, in Fountain Valley. The new building houses over 300 staff members that were previously spread across 10 buildings. Internal communications and engagement will need to become a greater focal point to ensure OC San’s culture remains positive between staff located at the Plants, and staff at Headquarters. Mission The Public Affairs Office is committed to communicating information about OC San in a timely, accurate and accessible way to the employees, the Board of Directors, our member agencies, elected officials, the public, and the news media. • We are committed to open, honest, clear, and respectful two-way communication with our audiences. • We are dedicated to informing others about how OC San serves the public and protects the environment. • We are committed to outstanding customer service by responding to requests quickly and efficiently. • We are dedicated to teamwork and collaboration as well as being creative and taking the initiative to be out in front of issues.

PAO Strategic Plan FY 2024-26 June 2024 6 To achieve these goals, PAO outlines the following strategies and tactics, along with the primary staff assigned to each area. Although individual staff members are the key contacts for each of the goals, the team works collectively and collaboratively, reflecting our core values. Our staff acknowledges the key role we play at OC San, not only communicating information, but also educating, consulting, and serving as a resource to our Board of Directors, employees, the wastewater industry, our member agencies, and our community. Flexibility is implemented into this plan to deal with unexpected situations and circumstances. Public Affairs Strategies and Tactics 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. SANTA ANA RIVER INTERCEPTOR (SARI) LINE – A regional brine line designed to convey 30 million gallons per day of non-reclaimable wastewater from the upper Santa Ana River basin to the ocean for disposal, after treatment. SANITARY SEWER – Separate sewer systems specifically for the carrying of domestic and industrial wastewater. SOUTH COAST AIR QUALITY MANAGEMENT DISTRICT (SCAQMD) – Regional regulatory agency that develops plans and regulations designed to achieve public health standards by reducing emissions from business and industry. SECONDARY TREATMENT – Biological wastewater treatment, particularly the activated sludge process, where bacteria and other microorganisms consume dissolved nutrients in wastewater. SLUDGE – Untreated solid material created by the treatment of wastewater. TOTAL SUSPENDED SOLIDS (TSS) – The amount of solids floating and in suspension in wastewater. ORANGE COUNTY SANITATION DISTRICT GLOSSARY OF TERMS TRICKLING FILTER – A biological secondary treatment process in which bacteria and other microorganisms, growing as slime on the surface of rocks or plastic media, consume nutrients in wastewater as it trickles over them. URBAN RUNOFF – Water from city streets and domestic properties that carry pollutants into the storm drains, rivers, lakes, and oceans. WASTEWATER – Any water that enters the sanitary sewer. WATERSHED – A land area from which water drains to a particular water body. OCSD’s service area is in the Santa Ana River Watershed.
