As OCSD embarks on another year of this renewed asset management program, we have updated our Asset Management Plan to be a tactical document summarizing our plans for addressing asset condition and performance issues. This Asset Management Plan will be published annually, and we anticipate this document will continue to change in content and structure as our asset management program evolves. Overview of OCSD’s Infrastructure OCSD is responsible for providing wastewater collection, treatment and recycling services to over 2.6 million people in central and northern Orange County, California. OCSD’s two resource recovery and wastewater treatment facilities treat an average daily wastewater flow of 185 million gallons per day (MGD) from residential, commercial and industrial sources. OCSD owns and operates wastewater collection system infrastructure as well as resource recovery and wastewater treatment facilities. Our collection system infrastructure includes 389 miles of regional trunk sewer pipelines and fifteen pump stations located throughout OCSD’s service area. This wastewater is conveyed to Reclamation Plant No. 1 in Fountain Valley and Treatment Plant No. 2 in Huntington Beach, where resource recovery and wastewater treatment take place. 2 Figure ES.1 shows the facility valuation by asset system for OCSD’s wastewater infrastructure. The valuation was prepared as part of the 2017 Facilities Master Plan. Figure ES.1. Facility Valuation by Location Collection System Piping, $3.23, 30.1% Collection System Pump Stations, $0.33, 3.1% Plant No. 1 Facilities, $2.77, 25.8% Plant No. 2 Facilities, $2.86, 26.6% Interplant Joint and Common Facilities, $1.55, 14.4% Facility Valuation (in $billions, 2017 dollars) $10.73Total Valuation: 3 Asset Management Intent, Policy, and Initiatives Reliable infrastructure is essential to achieving our mission and vision. We manage infrastructure reliability according to the following stated intent for our asset management program: “OCSD will know the condition of assets we own and will have a plan to operate and maintain these assets to deliver the required level of service at the lowest life cycle cost with an acceptable level of risk.” ~ James D. Herberg, OCSD General Manager In November 2019, OCSD’s strategic planning process resulted in the creation of an Asset Management Policy and Asset Management Initiatives. ASSET MANAGEMENT POLICY The Sanitation District will assess and manage the collection system and treatment plant systems and assets to improve resilience and reliability while lowering lifecycle costs. This will be accomplished through adaptive operation, coordinated maintenance and condition assessment, and planned capital investment. Staff will balance maintenance, refurbishment, and replacement strategies to maximize useful life, system availability and efficiency. ASSET MANAGEMENT INITIATIVES  Create an annual Asset Management Plan documenting the condition of the collection system and treatment plants, and upcoming maintenance or capital projects.  Coordinate the efforts of operations, collections, mechanical maintenance, electrical maintenance, instrument maintenance and engineering through process teams to assure the Sanitation District’s resources are focused on the high priority work functions.  Maintain a 20-year forecast of all CIP projects needed to maintain or upgrade the Sanitation District’s nearly $11 billion in assets on a prioritized risk basis to establish rate structures. 4 Asset Management Organization Asset management is not new to OCSD. As shown in Figure ES.2, every part of our organization is involved in some aspect of ensuring assets are designed, constructed, operated, and maintained to reliably deliver service to our customers. Figure ES.2. Roles in Asset Management To fulfill our commitment to our ratepayers for providing safe and reliable services, OCSD has augmented and solidified our asset management program and restructured the organization to better align the Engineering and Operations and Maintenance (O&M) departments. Through this restructuring, OCSD has established an Asset Management Group within the Planning Division consisting of nine Asset Engineers responsible for understanding the key issues or concerns related to the condition of OCSD’s assets and for developing and coordinating plans to ensure these assets operate reliably. 5 State of OCSD’s Infrastructure The following system-level summary tables provide a high-level overview of the Area Asset Management Summaries contained in CHAPTER 5. The system-level summaries are organized by:  Plant No. 1 (Table ES.1)  Plant No. 2 (Table ES.2)  Collection System – Pump Stations (Table ES.3)  Collection – Pipelines (Table ES.4) The system-level summaries generally include the following fields:  Area No.  Area Name  Average Remaining Useful Life (RUL) Score: Estimated average RUL score for each discipline (civil, structural, mechanical, electrical, and instrumentation) or area based on an average of the RUL scores provided by Asset Engineers in the detailed Area AM Summaries.  Percentage of RUL Scores with 4s or 5s[1]: Percentage based on total number of RUL scores assigned to each area by Asset Engineers in the detailed Area AM Summaries. The percentage is an alternate metric for the overall condition of the area. A RUL score of 5 indicates less than 5 years of useful life remains for an asset or set of assets. A RUL score of 4 indicates 5 to 10 years of useful life remains for an asset or a set of assets.  Replacement Value ($million): Process area replacement value from the facility valuation.

OCSD has been striving to more accurately identify medium- to long-term capital cash flow requirements. Fiscal Year 2019-2020 Budget Update, adopted on June 26, 2019, includes updates to the 20-year CIP outlay. Figure ES.3 includes current and projected Capital Improvement Program projects. Figure ES.3. 20-Year CIP Outlay $ mi l l i o n s 20-Year CIP Outlay 11 CHAPTER 1 PURPOSE Over the past two years, the Orange County Sanitation District (OCSD) has made a concerted effort to establish a baseline understanding of the condition and performance of all critical and major assets and our ability to meet established levels of service. As OCSD embarks on another year of this renewed asset management program, we have updated our Asset Management Plan to be a tactical document summarizing our plans for addressing asset condition and performance issues. This Asset Management Plan will be published annually, and we anticipate this document will continue to change in content and structure as our asset management program evolves. The current structure is organized into the following chapters to meet the needs of stakeholders:  Executive Summary: Summarizes purpose of the Asset Management Plan and main conclusions.  Chapter 1 Purpose: Outlines purpose and organization of the Asset Management Plan.  Chapter 2 Overview of OCSD’s Infrastructure: Describes the major infrastructure that OCSD owns and operates.  Chapter 3 Asset Management Intent, Policy and Initiatives: Defines organizational intents, policies, and initiatives driving the asset management program.  Chapter 4 Asset Management Organization: Describes the asset management organizational structure and asset management strategies.  Chapter 5 State of OCSD’s Infrastructure: Summarizes the current state of OCSD’s infrastructure and plans to address asset condition and performance issues.  Chapter 6 Program Monitoring and Improvements: Documents activities to monitor the asset management program and improvement opportunities.  Chapter 7 Budgetary Considerations: Summarizes CIP and maintenance expenditures, and planned maintenance projects. 12 This page is intentionally left blank. 13 CHAPTER 2 OVERVIEW OF OCSD’S INFRASTRUCTURE OCSD is responsible for providing wastewater collection, treatment and recycling services to over 2.6 million people in central and northern Orange County, California. OCSD’s two resource recovery and wastewater treatment facilities treat an average daily wastewater flow of 185 million gallons per day (MGD) from residential, commercial and industrial sources. OCSD owns and operates wastewater collection system infrastructure as well as resource recovery and wastewater treatment facilities. Our collection system infrastructure includes 389 miles of regional trunk sewer pipelines and fifteen pump stations located throughout OCSD’s service area (shown in Figure 2.1). This wastewater is conveyed to Reclamation Plant No. 1 in Fountain Valley and Treatment Plant No. 2 in Huntington Beach, where resource recovery and wastewater treatment take place. OCSD’s treatment plants currently operate under a permit from the Regional Water Quality Control Board (RWQCB). This was established by the National Pollutant Discharge Elimination System (NPDES) that permits the discharge of treated wastewater through an ocean outfall system to the Pacific Ocean. While some of this treated water is released five miles offshore through a deep-water ocean outfall system, most is recovered and delivered to Orange County Water District (OCWD). OCWD further treats OCSD’s effluent using the Groundwater Replenishment System, which improves the effluent water quality to drinking water standards for groundwater recharge and irrigation purposes. The following sections briefly describe the key systems under OCSD’s management. 14 Figure 2.1. OCSD Service Area 15 2.1 Collection System OCSD’s collection system serves as a regional conveyance system, collecting and conveying flows from 20 cities and four special districts. OCSD's 389 miles of collection system pipelines and 15 pump stations are spread throughout northern Orange County and include 365 miles of gravity pipelines, 20 miles of force mains, four miles of inverted siphons and 4,471 manholes structures. 16 2.2 Treatment Plant System OCSD owns and operates two wastewater treatment plants. Reclamation Plant No. 1 is located in the City of Fountain Valley, approximately four miles inland of the Pacific Ocean and adjacent to the Santa Ana River (shown in Figure 2.2). Influent wastewater entering Reclamation Plant No. 1 passes through a flow metering and diversion structure, mechanical bar screens, grit chambers, and primary basins, before going to one of two air activated sludge processes or trickling filters and secondary basins. Up to 135 MGD of secondary effluent can be diverted to OCWD’s facilities for tertiary treatment prior to reuse. Figure 2.2. Aerial View of Reclamation Plant No. 1 Solids treatment at Reclamation Plant No.1 includes co-thickening of primary and secondary sludge, followed by anaerobic digestion process and centrifuge dewatering of digested sludge to produce Class-B biosolids. Digester gas produced at Plant No. 1 is collected, compressed, cleaned, and transferred to the Central Power Generation Facility as a renewable fuel for energy generation. Plant No. 1 also has facilities for odor control and chemical addition. 17 Treatment Plant No. 2 is located in the City of Huntington Beach, adjacent to the Santa Ana River and east of Pacific Coast Highway (shown in Figure 2.3). Raw sewage flow entering Treatment Plant No. 2 passes through a flow metering structure, mechanical bar screens and grit removal chambers. Flow then passes through primary basins before being split between the oxygen activated sludge secondary treatment facility or trickling filters/solids contact and is discharged directly to the ocean via the outfall pumping system. Figure 2.3. Aerial View of Treatment Plant No. 2 Solids treatment at Treatment Plant No. 2 includes in-basin thickening of primary sludge, dissolved air flotation thickening of waste activated sludge and secondary sludge, anaerobic sludge digestion and centrifuge dewatering. Plant No. 2 also has facilities for odor control and chemical addition. Digester gas produced at Plant No. 2 is collected, compressed, cleaned, and distributed to a Central Power Generation System as a renewable fuel for energy generation. 18 2.3 Outfall System The ocean outfall system includes three discharge structures: Outfall No. 1, Outfall No. 2, and the Santa Ana River Emergency Overflow Weirs. Outfall No. 2 serves as the primary ocean outfall, discharging treated wastewater approximately five miles offshore at a depth of approximately 200 feet. It began service in 1971. Outfall No. 1 serves as an emergency outfall. It was originally constructed in 1954 and modified in 1965. It is located over a mile offshore at a depth of approximately 65 feet. OCSD’s NPDES permit specifies that this outfall can only be used in the case of an emergency or maintenance. The Outfall System has two Santa Ana River Emergency Overflow Weirs at Plant No. 2 which discharge directly to the Santa Ana River. These weirs are for extreme emergency use only. 19 2.4 Facility Valuation As part of the 2017 Facilities Master Plan, OCSD commissioned consulting engineering firms to conduct a study to determine the 2017 value of all OCSD capital facilities, including Reclamation Plant No. 1, Treatment Plant No. 2, interplant and joint treatment facilities, and the collection system, including sewer pipelines and lift stations. Figure 2.4 shows the valuation information presented in five general sub-process areas:  Collections Systems Piping  Collection Systems Pump Stations  Plant No. 1 Facilities  Plant No. 2 Facilities  Interplant and Joint Treatment Facilities Figure 2.4.

Figure 2.5. Facility Valuation by Area 21 CHAPTER 3 ASSET MANAGEMENT INTENT, POLICY AND INITIATIVES The Asset Management Plan is prepared in alignment with OCSD’s Mission, Vision, Asset Management Policy and Asset Management Initiatives approved by our Board of Directors. OCSD’s Asset Management Initiatives serve as a means for tracking progress towards meeting asset management objectives along with other performance measures. 22 This Asset Management Plan is a key component of OCSD’s overall planning activities. It is aligned with the District’s Strategic Plan, includes projects identified in the Facilities Master Plan, and identifies potential new activities requiring funding in the budget development process. Table 3.1 describes the relationship of the Asset Management Plan to other planning activities. Table 3.1. 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 OCSD and provides a basis for long-term financial, capital, and operating planning. The Asset Management Plan aligns with Strategic Plan goals and objectives. 5- to 10-year Biennial Facilities Master Plan Identifies long-term capital improvement plans to address treatment and collection system infrastructure needs. Projects identified in the Facilities Master Plan are incorporated into the Asset Management Plan and refined as appropriate. 20-year Varies Asset Management Plan Documents the overall condition of treatment and collection system assets and plans to address key condition and performance issues to ensure assets meet OCSD’s levels of service. 1-year 5-year 10-year Annual Budget Document Lays out the framework of OCSD’s activities and serves as a source of information for our Board of Directors, ratepayers and employees. Includes operational, capital and debt service expenditures necessary to support our mission and execute the Strategic Plan adopted by our Board of Directors. The Asset Management Plan identifies new maintenance and capital improvement activities for consideration in the budget development process. 2-year Annual 23 3.1 OCSD Mission and Vision Statements OCSD’s Board of Directors developed Mission and Vision statements to clearly communicate OCSD’s purpose to our stakeholders and to articulate OCSD’s organizational objectives. OCSD’s Vision supports our Mission by expressing what we strive to achieve now and into the future. OUR MISSION To protect public health and the environment by providing effective wastewater collection, treatment and recycling services. OUR VISION OCSD 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. We are achieving this mission through improved asset management practices to better coordinate and plan actions to ensure our collection system, treatment and resource recovery infrastructure works when we need it. One of the ways we are doing this in asset management is by defining clear roles and responsibilities for identifying the condition and performance needs of our assets. We work as a team to develop solutions and coordinate our efforts to solve these issues before they become problems that impact our ability to achieve our mission. This Asset Management Plan documents the key condition and performance issues identified by OCSD staff and our collective plans for addressing these issues. 24 3.2 Strategic Plan – Asset Management Policy and Initiatives Reliable infrastructure is essential to achieving our mission and vision. The stated intent of OCSD’s General Manager is: “OCSD will know the condition of assets we own and will have a plan to operate and maintain these assets to deliver the required level of service at the lowest life cycle cost with an acceptable level of risk.” – James D. Herberg, OCSD General Manager Related to the intent, the key objectives we are building into the asset management program include:  Proactive approach to repair, rehabilitation and replacement.  Ensure assets are reliable and operating when needed.  Minimize unplanned outages and equipment downtime.  Manage risks associated with asset or service impairment through asset performance optimization.  Develop cost-effective management strategies for the long term.  Strive to implement world class asset management strategies through continual improvement in our asset management practices. In addition, OCSD has a biennial strategic planning process designed to accomplish the following objectives:  Affirm corporate mission and vision.  Adjust strategic goals and policies.  Set agency-wide prioritization of initiatives.  Provide a disciplined budgeting process.  Set operational goals at the operating level.  Hold individual units accountable for performance. 25 The biennial strategic planning process is instrumental to aligning the activities OCSD’s staff performs with the strategic intent of the Board of Directors. In November 2019, OCSD’s strategic planning process resulted in the creation of an Asset Management Policy and Asset Management Initiatives. ASSET MANAGEMENT POLICY The Sanitation District will assess and manage the collection system and treatment plant systems and assets to improve resilience and reliability while lowering lifecycle costs. This will be accomplished through adaptive operation, coordinated maintenance and condition assessment, and planned capital investment. Staff will balance maintenance, refurbishment, and replacement strategies to maximize useful life, system availability and efficiency. ASSET MANAGEMENT INITIATIVES  Create an annual Asset Management Plan documenting the condition of the collection system and treatment plants, and upcoming maintenance or capital projects.  Coordinate the efforts of operations, collections, mechanical maintenance, electrical maintenance, instrument maintenance and engineering through process teams to assure the Sanitation District’s resources are focused on the high priority work functions.  Maintain a 20-year forecast of all CIP projects needed to maintain or upgrade the Sanitation District’s nearly $11 billion in assets on a prioritized risk basis to establish rate structures. Continual improvement in asset management practices is important. We are actively working to improve our implementation of the key objectives and our asset management capabilities, processes and systems through improved coordination in needs identification, solutions development, and project execution. This Asset Management Plan provides a summary of the condition of the collection system and treatment plants in CHAPTER 5 along with the upcoming maintenance and capital projects. CHAPTER 4 describes our approach to coordinating and focusing our efforts on high priority work functions. 26 This page is intentionally left blank. 27 CHAPTER 4 ASSET MANAGEMENT ORGANIZATION Asset management is not new to OCSD. Every part of our organization is involved in some aspect of ensuring assets are designed, constructed, operated, and maintained to reliably deliver service to our customers. Figure 4.1. Roles in Asset Management  Operations operates assets to convey, treat and recover resources.  Maintenance performs activities to maintain asset reliability.  Engineering Planning provides engineering support for short- to long-term management of assets.  Project Management manages design and construction of new facilities and the rehabilitation of older facilities.  Engineering Design ensures projects and assets are designed to meet stakeholder needs.  Construction Management ensures assets are constructed in accordance with contract requirements. To fulfill our commitment to our ratepayers for providing safe and reliable services, OCSD has augmented and solidified our asset management program and restructured the organization to better align the Engineering and Operations and Maintenance (O&M) departments. Through this restructuring, OCSD has established an Asset Management Group within the Planning Division consisting of nine Asset Engineers responsible for understanding the key issues or concerns related to the condition of OCSD’s assets and for developing and coordinating plans to ensure these assets operate reliably. The Asset Engineers work closely with O&M Area Team 28 members to maintain familiarity with operational, condition, and maintenance issues within their assigned areas. 4.1 Asset Management Coordination and Solutions Development The Area Teams are the starting point for leveraging field data to define issues requiring remediation. Area Teams are made up of plant operators, mechanics, electricians, instrument technicians and Asset Engineers. Figure 4.2 shows how field data is used to support coordination and solutions development for reporting issues to management and gaining project approval.  Coordination: Asset Engineers coordinate with O&M staff to understand asset conditions and needs based on staff knowledge, condition assessments (e.g., closed- circuit television [CCTV], corrosion assessments) and predictive maintenance data (e.g., vibration, infrared, oil quality). Asset Engineers update the area asset registries with estimated remaining useful life and relevant notes. Asset Engineers compile key issues and coordinate potential remediation activities, which are then presented to the Asset Management Council, consists of managers from all divisions within OCSD, during monthly presentations.  Solutions: Asset Engineers support solutions development and tracking. OCSD has developed SharePoint sites to track asset issues (i.e., Asset Issues Tracker) and to track solutions to asset issues executed by other divisions. Asset Engineers also define and prepare the potential work packages for the Clearinghouse review and approval. The Clearinghouse consists of managers from all OCSD divisions who come to a common understanding of issues facing OCSD and prioritize resources necessary to address those issues. After the project is approved by the Clearinghouse, it is turned over to a project team for execution. There are two sources of funding that may be used for projects approved by the Clearinghouse: Operating Budget and Capital Improvement Program.  The two-year Operating Budget is adopted biennially with an annual update. This budget includes funding for all programmed maintenance work and repairs to the facilities and infrastructure.  The Capital Improvement Program sets aside funds for projects that are planned to rehabilitate, replace, or extend the useful life of the facilities and infrastructure. 29 Figure 4.2. Coordination and Solutions Development Processes The following subsections describe the groups involved in the coordination and solutions development process of asset management. 4.1.1 Operations and Maintenance Area Teams The O&M Department has created Area Teams assigned to various process areas within the two wastewater treatment plants with the vision of being a top-notch, high-performing team that increases process efficiency and asset availability. The Area Teams consist of staff from operations and maintenance covering mechanical, instrumentation and electrical disciplines. Each Area Team is assigned an Area Champion (typically a supervisor) who assists the team through challenges, and aids in team collaboration and oversight. The Area Team is also assigned representatives from maintenance planning and an Asset Engineer from the Planning Asset Management Group (see Subsection 4.1.2). The teams help streamline efforts and align resources within the current organizational structure to integrate the skills, knowledge and insights from all levels of operations, maintenance and engineering. O&M Area Team members provide the Asset Engineer with a direct line of 30 communication to field staff operating within the process areas and serve as a central resource for information sharing and collaboration for solution development. 4.1.2 Engineering Planning OCSD’s Planning Division provides a comprehensive Capital Improvement Program (CIP) that considers projected capacity requirements, condition of current assets, projected regulatory, level of service changes and business opportunities. Capital Improvement Program Planning The Planning Division’s CIP Planning Group develops and maintains the 20-year CIP plan consisting of capital improvement projects that maintain reliability, accommodate future growth, as well as meet future regulatory requirements, level of service goals, and strategic initiatives. In 2017, the OCSD Board of Directors adopted the Facilities Master Plan which provides a 20- year roadmap setting forth OCSD’s long term Capital Improvement Program. This roadmap provides a framework for infrastructure improvements needed at our treatment plant facilities, 15 pump stations, and 389 miles of regional sewers. In the 2017 Facilities Master Plan, most of the projects identified are the result of the need to rehabilitate and replace aging infrastructure in the collection system and treatment plants. Asset Management The Asset Management Group within the Planning Division consists of nine Asset Engineers who are responsible for OCSD’s short- to long-term asset management goals. The primary responsibility of this group is to monitor the condition of assets, develop short to long-term planning for asset maintenance, rehabilitation and replacement, and identification, packaging and prioritization of maintenance and CIP projects. Asset Engineers are assigned to one or more defined process or collection system areas. They work closely with O&M to maintain familiarity with operational, condition, and maintenance issues within their assigned areas. They also serve as “ambassadors” for each of their assigned areas to ensure that high priority issues are addressed in a timely fashion, and as the first point- of-contact for asset issues to drive root cause analysis and condition assessment. The Asset Management group plans and conducts condition assessments of critical assets utilizing corrosion consulting engineers, and CCTV contracts (Figure 4.3). Asset Engineers also engage with maintenance and capital improvement project delivery teams to monitor the scope of work and timing of planned projects, to verify that the projects will address the identified issues in a timely manner. One of their key responsibilities is to define the scope, appropriate timing and budget requirements of future maintenance and CIP projects, which are the basis for future project, operations, and maintenance budget development. Moving forward, the Asset Engineers will have the primary responsibility for submitting CIP projects for Clearinghouse approval. Knowing the history, background information and the future plans for each specific area, the Asset Engineers are in a unique Figure 4.3. CCTV Inspection 31 position to coordinate asset maintenance and rehabilitation activities among various OCSD divisions. These coordination efforts support the goal of OCSD’s Asset Management Program, which is to lower lifecycle costs of infrastructure, at an acceptable level of risk, while continuously delivering OCSD’s established levels of service. Figure 4.4 illustrates the role Asset Engineers have in gathering information and understanding needs to support coordination, planning and communication of changes to the plans. Figure 4.4. Asset Engineer Role within Asset Management 4.2 Maintenance and CIP Project Execution 4.2.1 Project Management Office OCSD’s Project Management Office Division manages the design and construction of new facilities plus the rehabilitation of existing facilities to ensure the safe, cost effective transport, and treatment of influent/effluent. This division is responsible for the delivery of projects from the preliminary design stages through closeout of construction. The division provides standards, processes, and methodologies to improve project quality, cost, and timeliness. Small Project Delivery The Small Projects Delivery team is a support arm of the Operations, Maintenance, and Engineering divisions and is responsible for the design and construction of facilities and maintenance projects. The purpose of this team is to deliver short term projects to effectively manage life of existing assets and in doing so deferring construction of capital projects in the longer term. Project Engineers in the Small Projects Delivery team completes the scope of work, performs project design (in-house or by consultant), bids the project in collaboration with Contracts or Purchasing, and manages construction, implementation, commissioning, change management, and closeout. Asset Management Group Asset Engineers 32 Project Management The Project Management Group consists of engineers functioning as Project Managers for a range of CIP projects including design/construction projects, planning studies, CEQA studies, and research studies. Project Delivery Support The Project Delivery Support group supports the CIP and small projects with reporting and monitoring tools for budgets, costs, schedules, cost estimates, amendments, change orders, and resource and cash forecasting for all projects. 4.2.2 Design The Design division ensures that all projects are designed and constructed to be reliable, maintainable, and operable at optimum lifecycle costs in accordance with OCSD’s Engineering Standards and codes. The division also ensures that the electrical and control systems on projects are properly and safely constructed, commissioned, and executed in accordance with the contract documents with minimal impact to operations, maintenance, local agencies, and the public. The division provides process control SCADA system hardware, software and data network support for collections and treatment plant processes that are highly reliable, safe, secure, online, and available to monitor, record, control, and operate our facilities. This division’s role is also to provide commissioning support services during construction. The division includes the following groups:  Civil, Mechanical, and Process  Electrical and I&C  Process Controls Integration  Commissioning 4.2.3 Construction Management The Construction Management Division ensures timely and quality construction and commissioning execution. This division’s role is to provide construction management and inspection services for OCSD projects to ensure they are safely constructed and inspected in accordance with contract requirements and regulatory and legal codes while minimizing impacts to operations, maintenance, local agencies and the public. The division includes the following groups:  Plant No. 1 and Pump Stations  Plant No. 2 and Collections  Civil Inspection – Plant No. 1 and Pump Stations  Civil Inspection – Plant No. 2 and Collections  Electrical and I&C Inspection 4.3 Asset Maintenance The Maintenance division provides reliable maintenance to OCSD’s assets. Maintenance- related asset management involves implementing strategies that ensure OCSD’s assets will operate at a required level of service and the lowest lifecycle cost with an acceptable level of risk. 33 4.3.1 Maintenance Maintenance Reliability Group OCSD has developed a mature predictive maintenance (PdM) program, which is a core strategy for maximizing asset reliability for major rotating mechanical and electrical equipment. The premise of PdM is that regular monitoring of the actual mechanical condition of machine trains will lead to optimal intervals between repairs, minimize the number and cost of unscheduled repairs created by machine-train failures, and improve the overall equipment reliability. The Reliability Technicians use various techniques such as:  Vibration analysis to measure imbalance in rotating equipment.  Thermography to measure excessive heat.  Oil and wear debris analysis to predict failure of lubricants.  Ultrasound inspection of electrical power distribution equipment for detecting potential for arc flash incidents and mechanical rotating and stationary equipment. OCSD has a two-decade history of predictive maintenance as summarized in Table 4.1. Table 4.1. High-level Summary of OCSD’s PdM Program Year Activity 2002 Baseline vibration monitoring with consultant assistance 2006 Comprehensive vibration analysis program implementation at both treatment plants and 15 pump stations 2012 Comprehensive predictive maintenance program implementation and establishment of Reliability Maintenance Team that includes engineers and four Reliability Maintenance Technicians 2014 Predictive maintenance program assessment conducted by Allied Reliability Inc. 2018 Machinery lubrication program assessment conducted by Noria Corporation Inc.; Added ultrasound and thermography to test electrical equipment OCSD’s predictive maintenance and monitoring program is organized around the mechanical, electrical and civil disciplines. Figure 4.5. PdM Summary 34 Mechanical Discipline The mechanical discipline has the most mature PdM Program and involves variance trending of the PdM test results, which include:  Vibration analysis  Oil analysis  Ultrasonic  Infrared thermography  IRIS motion camera (measures deflection and displacement) In addition to PdM activities for mechanical equipment, OCSD also uses laser alignment techniques to enhance alignment rotating machinery accuracy to increase operating life span. Electrical Discipline The electrical PdM Program continues to evolve and currently includes the following tests:  Oil analysis for transformers  Ultrasound to detect arcing  Infrared thermography to detect hot spots  Electrical power distribution equipment preventive maintenance  Circuit breakers and protective relays preventive maintenance and testing Future tests expected to be added include:  Motor/generator circuit analysis  Medium voltage feeder cable testing to determine the health of cables and insulation Civil Discipline Civil maintenance covers proactive and corrective maintenance tasks for all OCSD civil assets at all facilities located at Plants No. 1 and No. 2, as well as all OCSD pump stations and collection system. Civil maintenance activities complement the existing maintenance programs for mechanical, electrical and instrumentation. Civil maintenance includes the following activities:  Valve and gate exercising program comprising more than 264 preventive maintenance tasks for over 1,650 valves and gates in both plants and collection system.  Equipment rotation program to ensure equipment wear is predictable.  Operating, maintaining and cleaning pump stations and associated facilities.  Chemical conditioning of the sewage to reduce corrosion and control odors. Figure 4.6. Vibration Analysis Equipment Figure 4.7. Infrared Thermography 35 In addition to these activities, OCSD also implements life extension measures to increase the useful life of expensive equipment through minor repairs, and corrosion control methods such as coatings and cathodic protection. Routine Maintenance Beyond the advanced predictive maintenance strategies used to cost-effectively extend equipment life, OCSD also performs routine time and cycle-based preventive maintenance (PM) activities including:  Adjustments and mechanical alignments  Electrical equipment cleaning and tightening  Sensors and meters calibration  Changing of lubricants and filters  Exercising equipment  Equipment rebuilding and regular testing Preventative Optimization OCSD created a new Preventative Maintenance Optimization Group that will be tasked with conducting an in-depth assessment to optimize planned maintenance strategies for new and existing assets and to establish maintenance approaches and strategies for assets installed by capital improvement projects prior to beneficial occupancy. The PM Optimization Program will track, maintain, and manage assets throughout their lifecycles from design, construction, commissioning, beneficial occupancy, operations and maintenance, to the eventual decommissioning or replacement of assets. This will ensure that asset lifecycle is maximized with the lowest risk to process failure by achieving the intended reliability, at the lowest possible cost, and maximizing equipment availability. Maintenance Planners Maintenance Planners are responsible for managing blanket maintenance service contracts, planning and scheduling of craft-based maintenance activities, optimizing preventive maintenance activities within Maximo, and coordination of complex maintenance activities involving shutdowns and outages. Maintenance Planners help drive reliability and effectiveness in the craft-based maintenance work groups they support by ensuring that work groups have sufficient ready-to-execute work with appropriate resources such as tools, materials, labor, and job plans. Maintenance Planners are the owners of preventive maintenance and job plans. They are responsible for maintaining preventive maintenance and job plan database within Maximo. They continuously improved preventive maintenance by fine tuning job plans based upon input received from field staff, leads, maintenance Supervisors and Engineers. 36 This page is intentionally left blank. 37 CHAPTER 5 STATE OF OCSD’S INFRASTRUCTURE The Area AM Summaries are intended to summarize the condition of major assets, identify key issues for further investigation, and summarize maintenance and CIP projects planned over the next ten years. The approach for developing the AM Summaries is to assemble a list of major assets, document key issues, define the average remaining useful lives of these assets, and identify OCSD’s plan to address performance and reliability issues of these assets over the one, five-, and ten-year planning horizons. Every AM Summary is presented to the AM Council once annually. Each month, an Asset Engineer presents one or more of the AM Summaries to the AM Council. The Area AM Summaries are updated as needed and incorporated into the AMP which is published annually. Asset Engineers maintain a detailed asset registry which is a primary data source for the Area AM Summaries. The asset registries generally include the fields shown in Table 5.1. Table 5.1. Asset Registry Fields Field Description/Example Asset Location Plant No. 1, Plant No. 2, or Collections Discipline Examples: Civil, structural, mechanical, electrical and instrumentation Category Examples: Process, non-process Asset Class Name Examples: Pump, valve Asset Description Example: Primary Clarifier 3 Loop Tag Location-based asset unique identifier Asset ID Asset unique identifier Year Built The year the asset was commissioned Original Project Code identifying under which project the asset was installed Useful Life (SP-151) Useful life estimates developed by project SP-151 Theoretical Remaining Useful Life Calculated remaining life based on installation date and Useful Life (SP-151) Field Adjusted RUL Score Remaining useful life adjusted based on field condition Upcoming CIP Project No. Associated CIP project that will impact asset Notes Text field including notes from Facility Master Plan or other field observations 38 5.1 System Summaries The following system-level summaries provide a high-level overview of the Area Asset Management Summaries contained in Section 5.2. The system-level summaries are organized by:  Plant No. 1  Plant No. 2  Collection System – Pump Stations  Collection System – Pipelines The system-level summaries include an area map showing the general layout of the process areas or collection system, and a table with the following fields:  Area No.  Area Name  Average RUL Score: Estimated average for each discipline (civil, structural, mechanical, electrical, and instrumentation) and area based on the detailed Area AM Summaries.  Average Remaining Useful Life (RUL) Score: Estimated average RUL score for each discipline (civil, structural, mechanical, electrical, and instrumentation) or area based on an average of the RUL scores provided by Asset Engineers in the detailed Area AM Summaries.  Percentage of RUL Scores with 4s or 5s[1]: Percentage based on total number of RUL scores assigned to each area by Asset Engineers in the detailed Area AM Summaries. The percentage is an alternate metric for the overall condition of the area. A RUL score of 5 indicates less than 5 years of useful life remains for an asset or set of assets. A RUL score of 4 indicates 5 to 10 years of useful life remains for an asset or a set of assets.  Replacement Value ($million): Process area replacement value from the facility valuation.

Some assets have very little remaining life or have failed already and will need interim solutions before they are addressed by the project.  Continue to actively monitor the condition of aging assets scheduled for repairs/replacement under P1-105 and develop temporary/minimal solutions as applicable until a permanent solution is provided by P1-105. In some instances, failed equipment may need to be replaced and removed from the P1-105 scope, but this approach should be minimized.  Steve Anderson Lift Station – Steve Anderson Lift Station has experienced vibration issues and equipment failures over the past few years.  New pumps without vibration issues are being installed to replace the existing pumps. These replacements are planned to continue until all four pumps have been replaced. Vibration of the new pumps should continue to be monitored to confirm their performance.  Rags – Rags have become an ongoing issue throughout the preliminary and primary process areas. The prevalence of rags is likely due to the rise in popularity of “flushable wipes”. Rags passing the barscreens have caused failures and increased wear on various mechanical equipment.  P1-105 will be replacing the existing 1-inch barscreens with 5/8-inch barscreens. This should reduce the number of rags passing the barscreens into the treatment process.

These issues require ongoing attention from maintenance and can affect Plant No. 1 treatment capacity.  A number of projects are planned to address rectangular primary basin issues and reliability including MP-462, P1-133, and X-017. However, these projects cannot make the rectangular basins maintenance free. OCSD should expect to dedicate a significant amount of maintenance labor to these basins, especially during times when capacity is reduced by projects. Also, a planned Preventative Maintenance approach should be taken for continued maintenance on the mechanical parts within the basins after work is complete on MP-462.  Construction Sequencing – There are many upcoming projects that will perform work on the Plant No. 1 primary treatment system. These projects are largely interdependent on one another and will temporarily impact the primary capacity at Plant No. 1.  Continue to holistically assess the capacity/treatment consequences of the upcoming projects, especially if schedules change during design and construction. Perform a study to understand if phasing the replacement of the circular primary basins under P1-126 is feasible.  GWRS Final Expansion – The final expansion of OCWD’s GWRS system is expected to be complete in 2023 and will produce 130 MGD of purified recycled water. This will require OCSD to provide more flow to OCWD.  OCSD is executing a number of projects to prepare for the GWRS Final Expansion. The most directly applicable is P2-122 which will provide additional flow to OCWD from Plant No. 2 while also increasing OCSD’s flexibility to route flows between Plant No. 1 and Plant No. 2. The optimization of flow routing will be an ongoing consideration for OCSD operations and should be periodically re-evaluated as operating conditions change.

In addition, if opportunity arises through future CIP or FE projects within areas where known air system deficiencies exist, we will address them at the time.  City Water Pump Station – Pumps are possibly undersized.  The three medium pumps at the City Water Pump Station continuously run causing excessive wear. There are 1 smaller jockey pumps that run very infrequently. Study is needed to properly size the pumps at the station to meet the current needs of the plant.  Reclaimed Water System – This system needs a pressure regulating valve installed.  Reclaimed water is meant to be a back up to plant water and to provide necessary support to Central Generation. When the pressure on the plant water side drops, the plant becomes in need of reclaimed water to compensate for the loss. Currently, the reclaimed water pressure varies between 100psi to 130psi, depending on the operational conditions at OCWD. OCSD plant water is at 80 psi, so with the current valves, reclaimed water with the higher psi tends to replace plant water, even when we are not in need. This causes unnecessary reclaimed water charges. Installing a pressure regulating valve at the OCWD/OCSD reclaimed water connection point will help reduce unnecessary charges and better manage our reclaimed water usage.

Last incident happened in July 2019, when the Grit Classifier A was lost due to the ground fault. Due to the complexity of the repair job and its impact to operations, need to develop a replacement plan for known failed cables.  880E located a spare wire for the Grit Classifier A and put back in service.  PRN-00409 P2 Headworks 480V Grounded Cable Repair was approved by the Clearinghouse to do the engineering design in-house and bid for service contract for repairs on damaged cables. The bid was awarded and will be presented to the December board for approval.  Main Sewage Pump System – P2-122 Headworks Modifications at Plant No. 2 for GWRS Final Expansion will replace 3 of 7 MSP pumps, but use the existing VFDs and Motors. They are due for overhaul to ensure that they continue to be reliable during and beyond the P2-122 construction. Also, current vibration monitoring system, which is Emerson CSI 4500, for MSP is obsolete and no longer supported after this year.  Variable frequency drives are halfway through their anticipated life cycle, so PRN-00528 P2 MSP Variable Frequency Drive Year 10 Preventative Maintenance was approved by the Clearinghouse to perform Year 10 Preventative Maintenance on the drives by the original equipment manufacturer.  PRN-00529 Plant No. 2 MSP Motor Overhaul was approved by the Clearinghouse to have the motors overhauled in the motor shop  Recommend replacing the obsolete vibration system with GE Bently Nevada since the District plans to standardize the vibration monitoring system.  Headworks – Asset life of P2-66 Headworks is relatively new, since it was completed in 2012. No condition assessment has been done in the past. There is a need to perform condition assessment at the Headworks to build a condition baseline.  With P2-122 construction starting next year, area engineer will coordinate with the project team and Operation and Maintenance to conduct condition assessments on areas that will be down for the construction.

With wet weather officially begins in October 15th, at least two basins need to be back in service, bringing the total available to 11 basins. With existing A-Side basins being demolished and replaced with new basins, B/ C side of basins need to be stay reliable for 10 years to support P2-98A construction.  Basins D, E, H, and I are down for repair through P2-98B B & C Side Interim Repair. Basin N is down due to the imbalance of the sweep arm. Basin N is scheduled to be assessed by OEM of internal mechanism to identify addition scope needed to put the basin back in service.  MP-692 P2 Primary Basin N Repairs is in place to cover additional items beyond P2-98B scope.  P2-98A and P2-133 are in place to provide long term solutions to all A, B, & C side of primary clarifiers.  Reliability of Waste Sidestream Pump Station C – Waste sidestream pumps and their associate equipment show accelerated corrosion issue due to the drains from the South Scrubber Complex. The South Scrubber Complex uses bleach for their scrubbers and the bleach pumps are oversized and do not have good turndown ratio. Excessive bleach goes to the drains that go to the WSSPS-C. The materials are not compatible with bleach, resulting accelerated corrosion.  MP-420 Plant No. 2 South Scrubber Complex Bleach Pump is in place to replace oversized bleach pump with smaller sized pump with better turndown capacity. This will reduce excess bleach that flows to the WSSPS-C.  Two failed pumps (5HP and 35HP) are sent out for root cause failure analysis and will be replaced with improved design.  X-054 WSSPS-C Rehabilitation at Plant No. 2 is in place to address corroded equipment caused by replacing equipment with upgraded material.

By then, EPSA system needs to stay reliable to compensate outfall capacity loss from OOBS being down. There are currently 3 ongoing projects to improve EPSA reliability, which are VFD cells refurbishment, motor cooling improvement, and EPSA discharge line assessment and repair  EPSA motors cooling issue has been approved by Clearinghouse (PRN-00519) by modifying the motor cooling with additional internal fans. This effort will be executed by the Small Capital Delivery group.  VFD cells refurbishment and control modernization approved by the Board. Plan is to complete the refurbishment and perform control upgrades by summer of 2020.  Issued a Purchase Order to perform a confined space entry assessment for EPSA discharge pipelines. Once the internal condition is known, repair plan will be developed.  OOBS & EPSA Overflow pipe and wing wall assessment – J-117A Interplant Effluent Pipeline Rehabilitation assessed OOBS overflow structure pipe segments and its concrete wing wall. The assessment identified separation of the pipe joints and deterioration of the wing wall  PS17-10 Emergency Overflow Weirs, Wing Wall Structural and Geotechnical Investigations is in place to investigate the root causes of the issues and provide recommendations to protect these structures. This study will feed into a FE project for execution.  Long Ocean Outfall Assessment – With long outfall pipe approaching 50 years in service, need an extensive assessment to understand maintenance required to extend the useful life. The permit with the California State Lands Commission was renewed for 25 years effective August 28, 2017, and the permit requires to maintain the outfall to use its land.  PS18-09 Ocean Outfall Condition Assessment and Scoping Study is in place to determine the condition of ocean outfall and provide recommendations to extend its useful life.  X-053 is created to execute rehabilitation efforts per recommendations from PS18-09. May need to assume similar condition to that of the 78” Outfall to address its condition.  Corrosion issues – Due to its corrosive environment, there are various areas that began to show signs of coating failure. There are areas, such as EPSA discharge line, that need to be assessed and Surge Tower welding joint between lower concrete and upper steel shell  Continue to work with coating team to address visible coating failures. PRN-00480 will repair the OOBS pipeline thermal expansion supports, and PRN-00566 will repair the external coating for OOBS & EPSA pipes  Coordinate with condition assessment team to develop work plans for welding joint and EPSA underground discharge assessment.

Also, pump station infrastructure is often located in the public right of way making safe access to these facilities an on-going issue.  A planning study has been established to review and interpret electrical code and establish OCSD design standards to address this issue. Practicing on-going safety measures and traffic control when working in the public right of way will continue to be of the utmost importance.  Natural Phenomenon – Edinger pump station is located immediately adjacent to an undersized flood control channel. Crystal Cove pump station is experiencing gradual site settlement. Both natural hazards present a risk to normal operation of the pump stations.  Siting analysis has identified an area farther away from the active flood control channel to which Edinger pump station may be moved. Also, the County of Orange is planning to increase the capacity of the channel to accommodate future planned flows. A planning study has been established to determine the necessary mitigation measures to remediate site settlement at Crystal Cove pump station.  Increased Methane Gas Levels – methane gas accumulation has become a safety concern at some pump stations. The amount of gas seems to increase during summer months and presents a unique challenge because of the short response time necessary to address the safety concerns of increased ignition risk.  OCSD crews respond to alarms that indicate increased levels of methane gas. An internal effort has been defined to place flow monitors in the system to collect necessary data prior to establishing a planning study to determine the cause of the gas accumulation and possible mitigation measures.  Corrosion – Corrosion is an on-going problem in this very harsh environment. In places were the system has been kept from venting and mixing of wastewater is prevalent, such as wet wells, the degree of corrosion has (or will soon) require the replacement/rehabilitation of the assets.  Visual assessments of known corrosion issues are performed on an on-going basis. When necessary, cameras are used to evaluate the spreading of corrosion impacts and confined space entry may be performed to gather additional information to determine when the facility needs to be rehabilitated.  Groundwater Intrusion – Groundwater has penetrated four of the newly constructed pump stations in the coastal region of the service area. Groundwater is notoriously corrosive and may compromise the strength of the rebar within the concrete structure walls.  Execute a planning study to identify possible mitigation measures.  Maintenance Access – In some cases, such as venting of the Newport Beach force main system, access to critical facilities is limited by safety and public impact concerns. In other cases, such as MacArthur Pump Station force main, access to critical facilities is not possible because redundancy was not considered when the pump station was designed.  OCSD continues to improve planned maintenance processes and inter-agency coordination that allow crews to minimize impacts to the community during necessary maintenance operations. A future capital project has been established to construct a redundant force main to serve MacArthur pump station.

To support the evaluation, OCSD is in the early stages (first year) of developing metrics for monitoring. The metrics will be included in subsequent AMP versions. 6.2 AM Program Improvement Opportunities Several improvement opportunities are defined in Table 6.1 as part of the AM Program continuous improvement process. Reasonable timeframes are defined for implementing these improvements. Future AMP updates will summarize the implementation progress. Table 6.1. AM Program Improvement Opportunities Improvement Opportunity Description Timeframe (Years) Success Measures Performance Management Framework and Metrics Establish metrics, processes, and organizational roles for tracking and trending the AM program performance and progress towards meeting the GM’s intent. 1-2  Defined metrics  Documented reporting processes Remaining Useful Life Continue to monitor and update the condition of assets and remaining useful life estimates for major assets. Ongoing  RUL estimate defined for each major asset Risk Assessment Expand existing risk assessment process and update likelihood and consequence of failure criteria. Score each major asset using the criteria. 2-5  Risk score for each major asset Integrated Use of Maximo Transition asset hierarchy and inventory, replacement costs, risk scores, and RUL estimates to Maximo to make it the system of record. 2-5  Maximo used as system of record  Elimination of Asset Engineer asset registry spreadsheets Life Cycle Costing Continue refining processes to track asset-level life cycle cost data. 2-5  Documented processes for conducting life cycle cost analyses  Formalized templates  Staff trained on processes and templates 132 This page is intentionally left blank. 133 CHAPTER 7 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. OCSD has been striving to more accurately identify medium- to long-term capital cash flow requirements. Specifically, the Planning Division has been working on developing a 20-year CIP by creating project plans for forecasted rehabilitation, replacement, improvements and expansion for the collection system and treatment plants. The CIP budget is being evaluated and updated on an on-going basis as new information becomes available. 7.1 Capital Improvement Expenditures Fiscal Year 2019-2020 Budget Update, adopted on June 26, 2019, includes updates to the 20- year CIP outlay. Figure 7.1 shows the 20-year CIP outlay which includes current and projected future Capital Improvement Program projects. Fiscal Year 2019-2020 CIP outlay is further divided into process categories shown in Figure 7.2. Figure 7.1. 20-Year CIP Outlay $ mi l l i o n s 20-Year CIP Outlay 134 Figure 7.2 CIP Outlay by Process Collections Facilities, $42.4, 24.1% Solids Handling & Digestion, $17.1, 9.7% Support Facilities, $25.2, 14.3%Utility Systems, $9.4, 5.3% Liquid Treatment, $54.6, 31.0% Other, $27.5, 15.6% FY 19-20 CIP Outlay by Process (in $millions) 135 7.2 Maintenance Expenditures 7.2.1 Five-Year Historical Maintenance Expenditures Figure 7.3 and Figure 7.4 show the historical actual spent versus budgeted operational and maintenance expenditures for the treatment plants and collection system, respectively.  The treatment plant expenditures include maintenance services and materials (budget objects 54010, 54020).  The collection system expenditures include maintenance services and materials (budget objects 54010, 54020).  These costs represent the operations and maintenance costs of fixed assets, including operationally funded repair/replacement projects. Figure 7.3. Five-Year Historical Maintenance Costs for Treatment Plants Figure 7.4. Five-Year Historical Maintenance Costs for Collection System 136 7.2.2 Three-Year Look-Ahead Maintenance Expenditures Table 7.1 shows operational-funded projects identified to-date and includes the projected annual expenditures. The projects are grouped by location (Plant No. 1, Plant No. 2, and Collection System), and then sorted by the project start fiscal year and estimated cost (highest to lowest). The list encompasses projects identified thus far. It is likely FY20-21 and beyond will fluctuate based on the condition of assets as they age. Additionally, projects in the following list represent expenditures that are operationally funded and capital in nature. Table 7.1.

The major revenue sources are as follows: • General Sewer Service Fees • Industrial Waste Permit User Fees • Capital Facilities Capacity Charges (CFCC) • Property Taxes • Interest Earnings • Other Miscellaneous Revenue • Debt Proceeds 2020-21 2021-22 General Service Fees – User fees are ongoing fees for service paid by customers connected to the sewer system. A property owner, or user, does not pay user fees until connected to the sewer system and receiving services. Once connected, a user is responsible for his share of the system’s costs, both fixed and variable, in proportion to his demand on the system. These fees are for both Single Family Residences (SFR) and Multiple Family Residences (MFR). FY 2020-21 is the third year of the most recent five-year sewer service fee rate schedule approved by the Board. The SFR rate (the underlying basis for all sewer rates) will increase by 1.2 percent ($4) in each year of the two-year budget to $343 in FY 2020-21 and to $347 in FY 2021-22. These rates are still well below the average annual sewer rate currently being charged throughout the state. $302.8M $307.5M 2 2020-21 2021-22 Industrial Waste Permit User Fees – Fees paid by large industrial and commercial properties owners connected to the sewer system. These fees are for the owner’s share of the system’s costs, both fixed and variable, in proportion to his demand on the system. Since the inception of the Permit User Fee program in 1970, users of the District’s system that discharge high volumes or high strength wastewater are required to obtain a discharge permit and pay for the full cost of service. $10.0M $10.2M Capital Facilities Capacity Charges (CFCC) – Capital Facilities Capacity Charge is a one-time, non- discriminatory charge imposed at the time a building or structure is newly connected to the District’s system, directly or indirectly, or an existing structure or category of use is expanded or increased. This charge pays for District facilities in existence at the time the charge is imposed, or to pay for new facilities to be constructed in the future, that are of benefit to the property being charged. $18.6M $18.7M Property Taxes – The County is permitted by State law (Proposition 13) to levy taxes at 1% of full market value (at time of purchase) and can increase the assessed value no more than 2% per year. The District receives a share of the basic levy proportionate to what was received in the 1976 to 1978 period less $3.5 million, the amount that represents the State’s permanent annual diversion from special districts to school districts that began in 1992-93. The District’s share of this revenue is dedicated for the payment of debt service. $99.0M $101.7M Interest Earnings – Interest earnings are generated from the investment of accumulated reserves consisting of a cash flow/contingency, a capital improvement, a renewal/replacement, and a self- insurance reserve. $6.4M $6.5M Other Revenue – Other revenue includes solids handling and capital assessments from the Irvine Ranch Water District (IRWD); and O&M sewer services provided to IRWD, the Santa Ana Watershed Protection Authority (SAWPA), and the Sunset Beach Sanitary District. $48.0M $50.2M 3 2020-21 2021-22 Debt Proceeds – Certificates of Participation (COPs) are the District’s primary mechanism for financing capital projects. COPs are repayment obligations based on a lease or installment sale agreement. COPs are viewed by the State of California as a share in an installment arrangement where the District serves as the purchaser. No new debt issuances are projected in the near- term. $0.0M $0.0M Financing If is necessary that the District utilize debt financing to meet its total obligations and to meet projected construction schedules, the District uses long-term borrowing (Certificates of Participation (COP)) for 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 is analyzed. No new debt issuance is currently being planned. The District Maintains its AAA Rating The District maintains ratings of “AAA” from Standards and Poor and “AA” from Fitch. A triple A rating is the highest obtainable for any governmental agency. In order to maintain this rating, the District adheres to its 2001 Debt Policy and coverage ratios requirements. This Board-adopted policy serves as the agency’s guide in the management of existing debt and in the issuance of future debt. OCSD Has Contractual Covenants The District has contractual covenants within the existing COP agreements which require minimum coverage ratios of 1.25. The minimum coverage ratio is the ratio of net annual revenues available for debt service requirements to total annual debt service requirements for all senior lien COP debt. The coverage ratio for senior lien COP debt was approved at 3.67 for FY 2019-20. Orange County Sanitation District Reserve Summary - FY 2019-20 Orange County Sanitation District (OCSD) has a Board of Directors Reserve Policy that sets forth seven criteria to be used to determine its reserve level. As part of the OCSD financial and operating process, we have developed a 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 are not seven different reserves, but seven criteria used to set the total reserve level. Reserves can only be used with the approval of the Board of Directors. Below is a brief summary of the OCSD Reserve Criteria. Reserve Policy Summary Non-Discretionary 1) Debt Covenants and Other Requirements – Required by OCSD bondholders – $94 million – RESTRICTED This level is set by various bond covenants. As OCSD issues debt, it is required to maintain certain levels of reserves held specifically for repayment of that debt and cannot be reduced or used prior to repayment of all outstanding debt issuances. 2) “Dry Period” – Property Tax Payments – 50% of Operating Costs – $84 million The largest portion of OCSD revenues are user fees, approximately $300 million. These fees are listed on and collected through the County property tax bill. Since we receive payments twice each year, we hold funds in reserve specifically to pay operating expenses pending receipt of those payments. 3) “Dry Period” – Property Tax Payments – 100% of August Debt Service Costs – $77 million The largest portion of OCSD revenues are user fees, approximately $300 million. These fees are listed on and collected through the County property tax bill. Since we receive payments twice each year, we hold funds in reserve specifically to pay debt service pending the receipt of those payments. Discretionary 4) Operating Budget – 10% of the total Operating Budget as a Contingency – $17 million We hold ten percent of our operating budget as an operating contingency for non-recurring and unanticipated expenditures. 5) Capital Improvement Budget – 50% of the average 10-year CIP Program – $137 million OCSD currently has a ten-year, $2 billion Capital Improvement effort. We hold the equivalent of 5% of that total as a contingency specifically related to these Capital Improvement Program efforts. 6) Rehabilitation and Refurbishment – $64 million In 2002, OCSD established a reserve level related to rehabilitation efforts at $50 million based on the rehabilitation or replacement costs at that time. Although the total costs for rehabilitation or replacement has increased substantially since 2002 as a result of the move to Full Secondary Treatment and the Construction of GWRS, this reserve guideline has only been increases 2% annually, making it potentially under-funded. 7) Catastrophic loss / Self-insurance – $57 million OCSD is Self-Insured for Catastrophic Loss. $57 million of the District’s total reserves are related to holding funds for this category. Although OCSD now has more than $10 billion in asset replacement value, this level has not been increased since its establishment more than 10 years ago, making it potentially under- funded. Current 2019-20 Reserve Policy Requirement $530 million Orange County Sanitation District ADMINISTRATION COMMITTEE Agenda Report Administration Building 10844 Ellis Avenue Fountain Valley, CA 92708 (714) 593-7433 File #:2020-953 Agenda Date:3/11/2020 Agenda Item No:5. FROM:James D. Herberg, General Manager Originator: Lorenzo Tyner, Assistant General Manager SUBJECT: OVERVIEW OF PROPERTY - LIABILITY INSURANCE GENERAL MANAGER'S RECOMMENDATION RECOMMENDATION: Information Item. BACKGROUND Staff will provide an informational presentation on the Orange County Sanitation District’s (Sanitation District)major insurance policies.The process of renewal begins each January,and final quotes are typically received in June, shortly before the beginning of the new fiscal year. The Sanitation District’s budget provides funds for the renewal of the following four (4)major insurances for Sanitation District operations: 1)Excess General Liability Insurance The Sanitation District’s Excess General Liability Insurance Program is currently provided through the California Municipal Excess Liability Program (CAMEL)and its sister program,the Alliant National Municipal Liability Program (ANML).The Sanitation District has participated in the CAMEL program since FY 1996-97. This program currently provides the Sanitation District with a $40 million dollar policy of comprehensive coverage for municipal liability,bodily injury and property damage,and personal injury.The program was structured to also include Employment Practices and Public Officials Errors &Omissions coverage.The $40 million dollar coverage has a self-insured deductible of $500,000.Since 1997,the Employment Practices portion of coverage has been enhanced from a $2 million dollar sub-limit to the full policy limit of $40 million dollars. 2)Excess Workers’ Compensation The Excess Workers’Compensation insurance coverage is with the California State Association of Counties Excess Insurance Authority (CSAC EIA).The Sanitation District has participated in this program or its predecessor since 2003.The Excess Workers’ Compensation program currently provides “Statutory”(unlimited)coverage with a self-insured retention (SIR),or deductible,of $1 million dollars.The use of Excess Workers’ Orange County Sanitation District Printed on 3/4/2020Page 1 of 2 powered by Legistar™ File #:2020-953 Agenda Date:3/11/2020 Agenda Item No:5. retention (SIR),or deductible,of $1 million dollars.The use of Excess Workers’ Compensation Insurance dates back to the late 1980’s. 3)All-Risk Property and Flood Insurance (Includes Boiler & Machinery Insurance) The All-Risk Property and Flood Insurance Program (Property Insurance)provides comprehensive coverage for much of the Sanitation District’s real and personal property regarding virtually all perils including fire, flood, and business interruption. Current Property Insurance limits are $1 billion dollars for most perils other than flood and earthquakes,and $300 million dollars for flood,with many sub-limits for various situations.In order to reach $1 billion dollars in limits,the broker had to arrange for more than a dozen different insurers. The SIR is $250,000 per occurrence for most types of losses. Since the late 1990’s,the Property Insurance has been with a nationwide joint purchase property insurance program called Public Entity Property Insurance Program (PEPIP),one of the world’s largest property programs.It is important to note that this joint purchase property insurance program offers the purchasing power of numerous large public entities without the pooling or sharing of coverage or losses. The Boiler &Machinery Insurance Program,part of the property insurance,provides comprehensive coverage for loss caused by machinery breakdown and explosion of steam boilers or other covered process equipment,including damage to the equipment itself and damage to other property caused by covered accidents.The current Boiler &Machinery Insurance Program provides coverage of $100 million dollars per occurrence with deductibles ranging from $25,000 to $350,000 for losses caused by covered machinery breakdown (e.g., motors,steam turbines,digesters,co-gen engines).Damages to the equipment,as well as damages to other property and improvements caused by the machinery breakdown,are covered by the Boiler &Machinery Insurance.This program augments the Sanitation District’s All-Risk Property Insurance that covers perils such as fire and flood. 4)Earthquake Insurance The Sanitation District previously carried earthquake insurance as part of its Property Insurance,but in the last 15 years earthquake insurance proved difficult to obtain or not cost- effective.The Sanitation District asked its insurance broker each year to survey the market to see if rates have changed.Finally,in 2015 a plan was created to insure several key Sanitation District structures identified by Engineering,thus keeping the cost in line.The insurance is a high deductible plan with a limit of $25 million dollars in total.
