OC San’s Fleet Services Division replaces vehicles as part of a fleet right-sizing and modernization strategy.The replacement is based on the current vehicle’s ability to meet the assigned departmental needs,vehicle age,maintenance cost,condition,and mileage.All proposed replacement vehicles and carts were identified as required for business needs during the fiscal year 2025-26 budget preparation process. The replacement vehicles are proposed annually during budget preparation.The Board subsequently approves vehicle procurements under the capital equipment section of the budget in June of each year.OC San enters into a purchase order agreement with entities that work directly with vehicle manufacturers to capitalize on the most cost-effective means to purchase the vehicles. OC San benefits from eliminating unnecessary options in the retail market through dealer shopping and ensures adherence to internal vehicle specifications. All vehicle purchases are evaluated for “Green”(electric,hybrid,CNG)technology applications to Orange County Sanitation District Printed on 9/2/2025Page 1 of 3 powered by Legistar™ File #:2025-4467 Agenda Date:9/10/2025 Agenda Item No:4. All vehicle purchases are evaluated for “Green”(electric,hybrid,CNG)technology applications to ensure adherence to the appropriate regulations. RELEVANT STANDARDS ·Participate in local, state, and national cooperative purchasing programs ·Ensure the public's money is wisely spent ·Maintain a proactive asset management program PROBLEM The vehicles and carts identified for replacement are nearing the end of economically useful life. Maintenance costs continue to increase,and the physical condition of the assets warrant significant restoration.Additionally,these older units lack modern safety features,which are key to keeping staff safe. PROPOSED SOLUTION Authorize the General Manager and Purchasing Manager to utilize the method of procurement determined to be in the best interest of OC San,to include cooperative contract,competitive solicitation,or sole source.This will allow staff to obtain vehicles in markets where inventory is readily available and meet the operational needs of the organization. TIMING CONCERNS OC San’s internal process requires additional committee and board action time,jeopardizing the ability to replace vehicles with external deadlines beyond OC San’s control.Granting authority to the General Manager and Purchasing Manager to target the most appropriate method to obtain the replacement units ensures the most optimal and cost-effective way to source the units. RAMIFICATIONS OF NOT TAKING ACTION The vehicles selected for replacement are costly,unreliable,and lack modern safety features currently required for fleet vehicles.Unscheduled maintenance costs are increasing,and vehicle reliability will compromise the mobility needs of staff. PRIOR COMMITTEE/BOARD ACTIONS N/A ADDITIONAL INFORMATION The requested vehicle type composition is shown in the table below,but may be substituted depending on the actual condition of the vehicle being replaced and market availability: Purchase Type Vehicle Type Quantity Cost Replacement SUV 10 $350,000 Replacement Cargo Van 3 $195,000 Replacement Service Pickup Truck 8 $591,600 Replacement Electric Utility Cart 12 $350,700 Orange County Sanitation District Printed on 9/2/2025Page 2 of 3 powered by Legistar™ File #:2025-4467 Agenda Date:9/10/2025 Agenda Item No:4.

BACKGROUND Orange County Sanitation District (OC San)has a recurring need for preventive and corrective maintenance on HVAC systems at its facilities.These systems are critical for cooling electrical,lab, and IT equipment, as well as maintaining a comfortable environment in occupied areas. RELEVANT STANDARDS ·Participate in local, state, and national cooperative service and purchasing programs ·Maintain a proactive asset management program ·Provide a safe and collegial workplace PROBLEM Extended material lead times,high volume of work,and aging equipment are causing HVAC maintenance delays and failures. Orange County Sanitation District Printed on 9/2/2025Page 1 of 2 powered by Legistar™ File #:2025-4473 Agenda Date:9/10/2025 Agenda Item No:5. PROPOSED SOLUTION Approve a BPO with Carrier Global Corporation for HVAC maintenance and repair services. TIMING CONCERNS HVAC equipment failures are occurring due to resource constraints and delays in performing preventive maintenance and repairs. This could lead to more costly total equipment replacements. RAMIFICATIONS OF NOT TAKING ACTION Failure to act could lead to critical HVAC equipment failure,potentially damaging systems that require a controlled environment and disrupting overall plant processes. PRIOR COMMITTEE/BOARD ACTIONS September 2023 -Approved a Blanket Purchase Order with Carrier Commercial Services for maintenance services of heating,air conditioning,and ventilation systems for Plant No.1,Plant No. 2,and pump stations,utilizing the Sourcewell Cooperative Agreement No.070121-CAR in accordance with Ordinance No.OC SAN-61,Section 2.03(B),for the period beginning October 1, 2023 through September 30,2024,for a total amount not to exceed $1,200,000 with two (2)one-year renewal options; and approved a contingency of $120,000 (10%). ADDITIONAL INFORMATION Sourcewell is a government unit that establishes competitively awarded cooperative contracts on behalf of itself and other participating agencies such as OC San.Utilizing this contract allows OC San to benefit from the significant discounts available on this contract which range from 35-71.5%off MSRP. CEQA N/A FINANCIAL CONSIDERATIONS This request complies with the authority levels of OC San’s Purchasing Ordinance.The recommendation will be funded under the Repairs and Maintenance line item for Administrative Services (Budget Update FY 2025-26, Page 23). The available funding is sufficient for this action.

FROM:Robert Thompson, General Manager Originator: Jennifer Cabral, Director of Communications SUBJECT: PUBLIC AFFAIRS UPDATE FOR THE MONTHS OF JULY AND AUGUST 2025 GENERAL MANAGER'S RECOMMENDATION RECOMMENDATION: Recommend to the Board of Directors to: Receive and file the Public Affairs Update for the months of July and August 2025. BACKGROUND Included in this report are recent activities of interest,managed by the Public Affairs Office for the months of July and August 2025. RELEVANT STANDARDS ·Maintain influential legislative advocacy and a public outreach program ·Maintain collaborative and cooperative relationships with regulators,stakeholders,and neighboring communities ·Listen to and seriously consider community input on environmental concerns PROBLEM The Orange County Sanitation District (OC San)is a distinguished entity in the water/wastewater industry.Despite our industry recognition,there may be limited awareness among our customers regarding the pivotal role we play in protecting public health and the environment.The absence of direct communication through a billing method may contribute to this gap in knowledge. It is our responsibility to ensure that our ratepayers comprehend the vital services we provide.Many customers may not realize that improper waste disposal into the sanitation system can adversely impact our sewer lines,reclamation plants,and the quality of water supplied through GWRS.By enhancing communication channels and fostering understanding,we aim to bridge the gap and empower our ratepayers with the knowledge needed to support and appreciate the essential work we undertake for the well-being of our community and the environment. Orange County Sanitation District Printed on 9/2/2025Page 1 of 4 powered by Legistar™ File #:2025-4469 Agenda Date:9/10/2025 Agenda Item No:6. PROPOSED SOLUTION By providing tours,community outreach,education,and general communication via OC San’s website,social media,and direct mailings,we can share information with the community,local agencies,and businesses on our messaging such as the What2Flush program,energy production, water recycling,biosolids,and our source control program.This,in turn,helps improve the quality of wastewater that is recycled or released to the ocean and the knowledge and understanding of wastewater treatment. RAMIFICATIONS OF NOT TAKING ACTION Failing to inform the community,local agencies,and businesses about OC San might result in insufficient support for our mission and hinder our effectiveness. PRIOR COMMITTEE/BOARD ACTIONS July 2025 -Received and filed the Fiscal Year 2024-2025 Year End Update to the Public Affairs Strategic Plan (FY 2024-2026).

FROM:Robert Thompson, General Manager Originator: Jennifer Cabral, Director of Communications SUBJECT: LEGISLATIVE AFFAIRS UPDATE FOR THE MONTHS OF JULY AND AUGUST 2025 GENERAL MANAGER'S RECOMMENDATION RECOMMENDATION: Recommend to the Board of Directors to: Receive and file the Legislative Affairs Update for the months of July and August 2025. BACKGROUND The Orange County Sanitation District’s (OC San)legislative affairs program includes advocating for OC San’s legislative interests;sponsoring legislation (where appropriate);and seeking local,state, and federal funding for projects and programs. RELEVANT STANDARDS ·Maintain influential legislative advocacy and a public outreach program ·Build brand, trust, and support with policy makers and community leaders ·Maintain collaborative and cooperative relationships with regulators,stakeholders,and neighboring communities PROBLEM Without a strong advocacy program,elected officials may not be aware of OC San’s mission, programs, and projects and how they could be impacted by proposed legislation. PROPOSED SOLUTION Continue to work with Local,State,and Federal officials to advocate for OC San’s legislative interests.Help to create and monitor legislation and grants that would benefit OC San,the wastewater industry,and the community.To assist in relationship building efforts,OC San will continue to reach out to elected officials through facility tours,one-on-one meetings,and trips to Washington D.C. and Sacramento.

RAMIFICATIONS OF NOT TAKING ACTION If OC San does not work with Local,State,and Federal elected officials,legislation could be passed that negatively affects OC San and the wastewater industry.Additionally,a lack of engagement may result in missed funding opportunities. ADDITIONAL INFORMATION Activities for July: Planning for the State of OC San has begun.The event is scheduled for Friday,October 17 from 11 a.m.to 1 p.m.at OC San’s Headquarters.The in-person event will feature State Water Resources Control Board Chair Joaquin Esquivel.Additionally,it will host Local,State,and Federal dignitaries. The event will provide an update on OC San,our accomplishments,and the future direction of the agency.Invitations are scheduled to go out in mid-September.Additional details will be provided as we approach the event date. Activities for August: The development of OC San’s annual Legislative and Regulatory Plan is underway.Over the next couple of months,OC San staff and our legislative consultants will review our current plan.From this,staff will draft the updated plan that will be presented to the Administration Committee in October,and the Board of Directors in November.The adopted Legislative and Regulatory Plan is used as the guiding document for legislative and regulatory activities in the 2026 calendar year. Activities for September OC San staff,along with our federal lobbyist,will continue working with the Environmental Protection Agency on the Community Funding Request for the Supercritical Water Oxidation Project.We expect to receive an update in September on the timing of project funding.

Since enactment of the One Big Beautiful Bill on July 4th, congressional activities centered on Fiscal Year 2026 spending bills. Because of bipartisan efforts to force a House vote on a resolution calling on the Administration to release the “Epstein Files”, the Speaker recessed earlier than anticipated to block a vote on the resolution. As a result of the early recess, several bills that were scheduled for floor votes were shelved until the House returned to work in September. This included the Promoting Efficient Review for Modern Infrastructure Today Act (PERMIT Act, H.R. 3898). H.R. 3898 would, among other matters, provide for ten-year National Pollutant Discharge Elimination System (NPDES) permits for water agencies. The Administration continued its reorganization efforts and reviewing PFAS standards for water and wastewater facilities’ compliance. The following summarizes the status of these and other policy issues of interest to OC San. House and Senate Appropriators Mark-Up Fiscal Year 2026 Appropriations The House Committee on Appropriations approved the U.S. Environmental Protection Agency’s (USEPA) Fiscal Year 2026 spending priorities. The committee reported out the bill along a party-line vote. The Senate Committee on Appropriations also acted upon its USEPA spending bill. However, unlike the House bill, the Senate appropriators approved their spending bill on a bipartisan vote of 26-2. Importance of Appropriations Process Despite the movement on the USEPA spending bill, the ongoing disputes centering on impoundment of funds and potentially additional rescissions of Fiscal Year 2025 spending decisions complicates the outlook of final passage of Fiscal Year 2026. If Congress can develop compromise funding bills, it is unlikely to occur before November or December. Absent an agreement, a full year Continuing Resolution would be required throwing in doubt funding of projects since such measures do not provide funding for congressionally directed project spending. PFAS Mandates The pending legal challenge to USEPA’s designation of Per- and Poly�luoroalkyl substances (PFAS) under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) that triggers potential liability for the water sector remains on hold as the agency reviews its options on how to proceed with the legal challenge. The agency is expected to provide the court with its position on whether it will defend against the litigation �iled by the Chamber of Commerce and other groups in the coming months. Because the litigation is based upon the process used to designate PFAS as a hazardous substance, the decision to defend or not will rest upon whether the agency believes it followed the Administrative Procedures Act in designating the chemicals. On August 14, the agency closed the public comment period for its Draft Risk Assessment Model that would set a 1 part-per-billion (PPB) exposure level for PFAS in biosolids. The public comment period generated more than two thousand comments on the pending Draft Risk Assessment. The comments, including those from CASA, cited the lack of validated science that the agency relied upon to develop the model. The agency also held listening sessions with key groups, including biosolids managers, drinking water and clean water stakeholders. In the listening sessions, the agency was informed that the model relied upon inaccurate data and assumptions to arrive at the stringent 1 PPB standard that would foreclose the use of land application of biosolids. The agency did not indicate how it perceived such positions except to note that it believes the staff-developed model remains the focus. At the same time, agency staff indicated that any decision on the model’s �inalization will be determined by senior political appointees. The House spending bill for the agency included language that, if enacted into law, would bar �inalization of the model. However, the agency could continue collecting data and other information. This presumably would allow the agency to follow through on the Administrator’s priority to re-examine the development of the model. In the Senate, there were no substantive amendments to the agency’s spending bill, except to reaf�irm support for the 4 parts per trillion drinking water standard and the designation of PFAS as a hazardous substance under Superfund. The spending bill also provides the agency with $9 million to support ongoing research into plant and animal PFAS uptake as well as potential groundwater impacts. Importance of PFAS Mandates The ongoing litigation related to the PFAS rules, and the delayed �inalization of the Draft Risk Assessment Model is important because it creates ongoing uncertainty on 1) what the �inal drinking water standard will be, and 2) what are acceptable management practices for biosolids. As a result in the absence of federal policies and standards, water and wastewater agencies will be subject to state mandates. This is important particularly in the case of biosolids. The 1PPB level of the draft Risk Assessment Model has been relied upon by several states which, if implemented, would effectively eliminate the continued land application of many biosolids. Because of this potential, stakeholders are urging the agency to issue national guidance on an approach that some states have adopted, one based on more realistic science regarding PFAS levels in biosolids and the exposure pathways from biosolids that the agency has not adequately addressed. It also emphasizes source control to reduce PFAS loadings into treatment works. Should the agency issue such guidance in the absence of �inal rules governing biosolids, it would help ensure that biosolids management practices protective of public health and the environment are maintained NPDES Permitting and Clean Water Act Reforms Legislation The House Committee on Transportation and Infrastructure’s PERMIT Act (H.R. 3898) remains in the House calendar. The bill includes ten-year NPDES permit terms, exemptions from Waters of the US de�initions for wastewater and groundwater, and codi�ies the Supreme Court’s decision on narrative nutrient standards (City & County of San Francisco v. EPA). It also contains other provisions to streamline the Clean Water Act permitting. The House is expected to debate and vote on the bill in September at the earliest. In the Senate, the Environment and Public Works Committee is working on bipartisan permit reform legislation. Updates to NPDES permit terms are reportedly under discussion. Importance of Legislation Passage of H.R. 3898 would set the stage for the Senate to consider Clean Water Act permitting reforms. If the Senate committee considers permit reforms, which currently enjoy bipartisan interest, the prospect for enactment would increase signi�icantly. If enacted, NPDES permittees would bene�it from reduced administrative burdens and savings related to compliance costs. In addition to the permit term provision, the codi�ication of the nutrient decision would ensure that any Clean Water Act nutrient mandates imposed upon point sources would be based upon statutory directives. This provision, if enacted, would eliminate a situation that occurred with the WOTUS rulemaking where a lack of clarity on WOTUS de�initions complicated compliance obligations. OC San has sent letters of support for NPDES permit extension to the congressional delegation.

Absent an explicit liability protection provision such agencies would be exposed to liability simply because an agency treated water and wastewater that contained PFAS chemicals and disposed of residuals and biosolids. Outlook: H.R. 1267 represents a placeholder bill to address the water sector's concerns over the potential liability created by USEPA's designation of PFAS as a hazardous substance under CERCLA. Both the House and Senate committees with jurisdiction over CERCLA have expressed interest in addressing PFAS liability. Legislative language could be drafted for committee consideration later this summer. However, any significant legislative activity is expected to await USEPA's recommendations on how to address passive receivers liability created by the PFAS designation.

Legislators have returned to their districts for constituent meetings, tours, and negotiating the fate of active bills ahead of key deadlines during August and September. When the Legislature resumes after the recess, the final stretch of the 2025 legislation promises to be active and consequential as high-impact policy initiatives will move quickly. On deck are measures related to land use, fiscal policy, housing and homelessness, transparency, immigration response, and emergency relief. The schedule for the End of Session is as follows: • August 18: Legislature reconvened • August 29: Appropriations Committees Held Suspense File Hearings • September 2-12: Floor Sessions Only o September 5: Was the last day to amend bills on the Floor • September 12: Legislature adjourns for the year • October 12: Deadline for Governor to sign or veto bills July 2025 Finance Bulletin: Year-End Revenue Update On July 24, the California Department of Finance released its July 2025 Finance Bulletin, announcing that the state closed the 2024–25 fiscal year with General Fund revenues about $2.7 billion above projections from the Governor’s May Revision. However, nearly half of this gain came from one-time federal reimbursements for prior-year costs. While these temporary payments help relieve short-term fiscal pressures, they do not reflect ongoing growth in the state’s major revenue streams—personal income, sales, and corporate taxes. Consequently, the surplus should not be viewed as evidence of a sustained improvement in California’s economy or tax base. As of June 30, the State Controller’s Office reported a General Fund cash balance of $34 billion, sufficient to meet current obligations. The State Treasurer also valued the Pooled Money Investment Account—which combines state and local government funds—at $178 billion at the fiscal year’s close. 2 While the year-end figures offer some positive indicators, the reliance on nonrecurring funds underscores the importance of cautious budgeting and long-term planning. The coming fiscal cycle will likely require continued attention to both revenue trends and expenditure pressures. Mid-Cycle Congressional Redistricting Proposal California lawmakers are preparing to take up a mid-cycle congressional redistricting proposal, a rapidly evolving development tied to national trends. When the Legislature reconvenes from Summer Recess on August 18, members are expected to introduce or amend legislation—or potentially a constitutional amendment—authorizing the redistricting process. Hearings are anticipated the week of August 18–21, with floor votes possible as early as August 22. If approved, the measure would trigger a gubernatorial proclamation for a November 4 special election. Passage would permit the Legislature to redraw congressional districts for the 2026, 2028, and 2030 election cycles. The proposal could face legal challenges and may bypass the standard referendum period. Orange County districts are expected to be among those affected, potentially altering OC San’s elected representation. STATE LEGISLATURE As we enter the final month of California’s legislative session, TPA is closely monitoring key bills that could impact OC San operations. We expect significant legislative activity and will continue to engage with lawmakers to ensure our priorities are represented. Key issues of significance to OC Open Meeting Legislation: Public Participation and Operational Flexibility Since certain Brown Act requirements were suspended for local governments during the COVID-19 pandemic, the Legislature has grappled with impending sunsets, equity concerns, procedural hurdles, and operational flexibilities across a variety of legislative proposals. The most notable of the Brown Act measures, SB 707 (Durazo) and AB 259 (Rubio) (OC San on a “Watch” position for both), were recently merged and will see new amendments before the End of Session. In the last month of session, themes that still need to be addressed in SB 707 include: • Implementation Timelines: Impacted entities have requested a delayed implementation of the two-way communications requirements to give more time to source the required hardware and software. • Meeting Disruptions: Clarifications are needed on how to address obscene or inappropriate behavior from Zoom calls during the public comment portion of meetings. • Internet Disruptions: Clarifications are needed on the ability to continue the public meeting in the event internet connectivity is compromised, or if the link to the live stream fails after the meeting has already started. 3 • AI Translation: Clarifications are needed to ensure that artificial intelligence translation, not merely digital translation, is acceptable. Local governments have requested amendments to allow more flexibility in how translated agendas are made available. Instead of relying only on physical postings, agencies could meet requirements through electronic kiosks or online platforms. If signed into law, OC San will need to ensure compliance with these new requirements. Cap and Trade Expenditure Plan Most of the state’s 2025 budget has been established through SB 101 (the 2025 Budget Act, passed June 13), AB 102 (the first Budget Bill Jr.), and various trailer bills. Additional activity is expected in August and September to finalize the spending plan, including revisiting Proposition 4 bond allocations, reviewing Greenhouse Gas Reduction Fund (GGRF) expenditures through Cap and Trade reauthorization, and addressing conformity issues related to H.R. 1. In April, Governor Newsom announced his commitment to permanently extend the Cap and Trade program before its expiration in 2030. This program generates revenue through the auction of greenhouse gas emission allowances, which is deposited into the GGRF. Most of this funding is dedicated to specific climate-related programs, such as the Affordable Housing and Sustainable Communities Program, the Low Carbon Transit Operations Program, and the High-Speed Rail Project, while the remaining revenue is available for discretionary spending determined by the Legislature through the annual budget process. The enacted budget approved the newly named “Cap and Invest” May Revision Finance Letter, which amended or eliminated various budget items to be determined later. It adjusted the GGRF allocation to CAL FIRE down to $500 million and included intent language regarding future shifts from GGRF to CAL FIRE. For High-Speed Rail, discussions on a $1 billion annual appropriation were deferred to the broader reauthorization process. As a result of these deferred decisions, legislators are expected to play a larger role in shaping future GGRF funding allocations. Earlier this year, Governor Newsom proposed a multiyear spending plan to implement Proposition 4, with a sum of $2.7 billion to be allocated in 2025-26. Until 2040, the Safe Drinking Water, Wildfire Prevention, Drought Preparedness, and Clean Air Bond Act of 2024 is slated to authorize $10 billion towards a variety of climate, energy, and wildfire-related projects and programs overseen by about 30 different state entities. This year’s allocations are expected to include the following commitments, according to the Governor’s proposed spending plan: • $1.074 billion for Safe Drinking Water, Drought, Flood, and Water • $325 million for Wildfire and Forest Resilience • $173 million for Coastal Resilience • $286 million for Biodiversity and Nature-Based Climate Solutions • $275 million for Clean Energy • $286 million for Park Creation and Outdoor Access 4 • $102 million for Extreme Heat Mitigation • $134 million for Climate Smart Agriculture AB 100, a Budget Bill Jr. amending the 2023 and 2024 Budget Acts, accelerated $181 million in Proposition 4 funding for wildfire prevention activities across the state as part of the recovery package for the Eaton and Palisades fires. In total, around $300 million in Prop 4 funds were shifted to backfill General Fund costs due to the state’s strained budget position. Some Prop 4 funds were also allocated to several departments to support staff related to bond appropriations. Discussions on spending and project eligibility are expected to resurface in follow-up budget trailer bills. Conversations around the Cap and Trade/Cap and Invest program are particularly relevant given the advocacy efforts of OC San board and staff for funding a new biosolids management program. TPA continues to push for this funding to be included in future expenditure plans.

By restricting the time period in which a local agency may respond to requests, thus increasing the duties of local officials, this bill would create a state- mandated local program. Current law requires each agency, within 10 days of a request for a copy of records, to determine whether the request seeks copies of disclosable public records in possession of the agency and to promptly notify the person of the determination and the reasons therefor. Current law authorizes that time limit to be extended by no more than 14 days under unusual circumstances, and defines “unusual circumstances” to include, among other things, the need to search for, collect, and appropriately examine records during a state of emergency when the state of emergency currently affects the agency’s ability to timely respond to requests due to staffing shortages or closure of facilities, as provided.

Key changes include: o New protections for whistleblowers o A requirement that Supervisors review and sign the code of ethics when taking office o An explicit rule that county officials and employees “shall not act for personal gain” • The same week the Board adopted the revised code of ethics, a federal judge ordered former 1st District Supervisor Andrew Do to repay about $878,000 to the County. Do also reported to the federal penitentiary in Tucson, Arizona, to begin serving his five-year prison sentence. • The Board also approved a plan to fold the District Attorney’s Human Resources (HR) Department into the County’s Central Administration. The change follows a civil lawsuit in which a jury awarded $3 million to a former prosecutor who claimed she was pushed out after trying to protect junior colleagues. Eight HR positions from the District Attorney’s office will be transferred as part of the move. • Across the County, several cities are experiencing leadership changes. Former Laguna Hills City Manager Jared Hildebrand has taken the top role in Orange. In Fullerton, former Westminster City Manager Eddie Manfro has been appointed Interim City Manager after serving as the city’s Human Resources Director. Mike Egan continues as Interim City Manager in La Palma. • Elsewhere in the county, the Yorba Linda City Council is reviewing candidates to replace City Manager Mark Pulone, who will retire in September. In Newport 2 | P a g e Beach, the City Council announced that Assistant City Manager Seimone Jurjis will step into the City Manager role on January 1, 2026, succeeding Grace Leung. • Negotiations continue between the County of Orange and a coalition of cities and sanitation districts regarding landfill tipping fees. The goal is to finalize an agreement by October. The next County Waste Management Commission meeting is scheduled for Thursday, September 11. • Advocates for the long-awaited Orange County Veterans Cemetery at Gypsum Canyon celebrated the passage of Assembly Bill 571. The bill exempts the cemetery site from unnecessary environmental reviews that could delay the project. The Federal Veterans Administration has identified Gypsum Canyon as the only suitable site for a veterans cemetery in Orange County. The project, which has received $55 million in state and county funding, now needs to secure placement on the Federal VA priority list. • County management staff recently met with representatives from the State Natural Resources Agency to discuss funding through Proposition 4, the $10 billion water, wildfire, and climate project bond passed by voters in 2024. Proposition 4 will fund projects designed to prevent and mitigate the impacts of droughts, flooding, wildfires, extreme heat, sea level rise, and carbon pollution. The Governor and State Legislature have been developing the criteria and process for grant applications for local government agencies, including special districts. • Longtime Costa Mesa Sanitary District (CMSD) Board member Arlene Schafer announced her retirement, effective August 1. Board member Schafer began her public service career in 1978 when she was elected to and served for eight years on the Costa Mesa City Council, including serving as Mayor from 1980-1982. She first served on the CMSD Board of Directors from 1994-2010, was subsequently appointed back to the Board in 2013 and was re-elected to serve three consecutive terms from 2014 through 2026. • Phase II of Orange County’s Climate Action Plan, a comprehensive roadmap detailing potential projects and programs to reduce greenhouse gas and other emissions from various sources, is on track to come to the Board of Supervisors on November 4. Key initiatives within CAP included increasing stormwater capture and infiltration, reducing the amount of organic waste going to landfills by 75 percent and improving edible food recovery by 20 percent, and exploring the feasibility of regional anaerobic digestion and conversion technology facilities.

That the Orange County Sanitation District Financing Corporation approve the documents supporting and authorizing the Revenue Obligations in an aggregate amount not to exceed $120,000,000. BACKGROUND July 2025 -Authorized the General Manager to pursue fixed a rate refunding of the 2016A Revenue Obligations.Approval of the recommended actions and the associated documents will enable staff to complete the refunding. March 2016 -Adopted Resolution No.OCSD16-03,authorizing the execution and delivery by the District of an Installment Purchase Agreement,a Trust Agreement,an Escrow Agreement and a Continuing Disclosure Agreement in connection with the execution and delivery of Orange County Sanitation District Wastewater Refunding Revenue Obligations,Series 2016A,authorizing the execution and delivery of such Revenue Obligations evidencing principal in an aggregate amount of not to exceed $163,000,000,approving a Notice of Intention to Sell,authorizing the distribution of an Official Notice Inviting Bids and an Official Statement in connection with the offering and sale of such Revenue Obligations and authorizing the execution of necessary documents and related actions;and that Orange County Sanitation District Financing Corporation approved the documents supporting Orange County Sanitation District Printed on 9/2/2025Page 1 of 4 powered by Legistar™ File #:2025-4263 Agenda Date:9/10/2025 Agenda Item No:8. that Orange County Sanitation District Financing Corporation approved the documents supporting and authorizing the Revenue Obligations in an aggregate amount not to exceed $163,000,000. RELEVANT STANDARDS ·Comply with OC San Debt Policy -Financial Management and Procedure 201-3-1;Net present value savings are at least three (3)percent of the par amount of the refunded bonds from refunding outstanding bonds PROBLEM The interest rates payable on the 2016A Revenue Obligations are higher than current market yields. PROPOSED SOLUTION The issuance of up to $120,000,000 of Wastewater Refunding Revenue Obligations,Series 2025A would allow OC San to refund up to all of the outstanding 2016A Revenue Obligations using a refunding amortization structured with the objective of providing level annual debt service savings (in years with principal maturing)and to generate net present value debt service savings of approximately $10.4 million (equal to 9.5%of refunded principal),based on market conditions as of August 27, 2025. TIMING CONCERNS OC San has the option of early redemption of the 2016A Revenue Obligations as of February 1, 2026.If the 2016A Revenue Obligations remain outstanding past the earliest optional redemption dates, OC San would pay interest costs above current market yields.

ADDITIONAL INFORMATION Since this is a fixed-rate debt issuance,staff is proposing to issue the refunding through a competitive sale because it is the most expeditious way to access the market,and it is expected to provide the lowest costs for this given structure.All costs involved with the refunding,including costs for PFM Financial Advisors LLC (Municipal Advisor)and Norton Rose Fulbright US LLP (Special Counsel and Disclosure Counsel), will be paid from the proceeds of the new refunding issue. For the anticipated issuance of 2025A Revenue Obligations,OC San’s Municipal Advisor,Public Resources Advisory Group,estimates,based on market conditions as of August 27,2025,and subject to changing market conditions which may result in the figures being higher or lower,the following: a)true interest cost of 3.14% (currently 4.97%); b)sum of all fees and charges paid to third parties of $864,775; c)net proceeds of $111,347,315; and d)total payments of $136,766,372. Legal Authorization and Approvals The OC San Board of Directors and Financing Corporation will each be required to adopt separate Resolutions to complete this refunding.A Financing Corporation is required by the structure of the Revenue Obligations and was formed in April 2000 solely to satisfy this need.The Board of Directors of the Corporation are the same as the Board of Directors of OC San,and the Corporation meets after an adjournment of the OC San Board meeting.

If the Trustee executes and delivers temporary Revenue Obligations, it shall prepare and execute definitive Revenue Obligations without delay, and thereupon the temporary Revenue Obligations may be surrendered at the Principal Office in exchange for such definitive Revenue Obligations, and until so exchanged such temporary Revenue Obligations shall be entitled to the same benefits hereunder as definitive Revenue Obligations executed and delivered hereunder. Section 2.09. Revenue Obligations Mutilated, Lost, Destroyed or Stolen. If any Revenue Obligation shall become mutilated, the Trustee, at the expense of the Owner thereof, shall execute and deliver a new Revenue Obligation evidencing a like principal amount and having the same stated Principal Payment Date and number in exchange and substitution for the Revenue Obligation so mutilated, but only upon surrender to the Trustee of the Revenue Obligation so mutilated. Every mutilated Revenue Obligation so surrendered to the Trustee shall be canceled by it. If any Revenue Obligation shall be lost, destroyed or stolen, evidence of such loss, destruction or theft may be submitted to the Trustee, and if such evidence is satisfactory to the Trustee and indemnity satisfactory to the Trustee shall be given, the Trustee, at the expense of the Owner thereof, shall execute and deliver a new Revenue Obligation evidencing a like principal amount and having the same stated Principal Payment Date, numbered as the Trustee shall determine, in lieu of and in substitution for the Revenue Obligation so lost, destroyed or stolen. The Trustee may require payment of a sum not exceeding the actual cost of preparing each new Revenue Obligation executed and delivered by it under this Section and of the expenses which may be incurred by it under this Section. Any Revenue Obligation executed and delivered under the provisions of this Section in lieu of any Revenue Obligation alleged to be lost, destroyed or stolen shall be equally and proportionately entitled to the benefits hereof with all other Revenue Obligations executed and delivered hereunder, and the Trustee shall not be required to treat both the original Revenue Obligation and any replacement Revenue Obligation as being Outstanding for the purpose of determining the amount of Revenue Obligations which may be executed and delivered hereunder or for the purpose of determining any percentage of Revenue Obligations Outstanding hereunder, but both the original and replacement Revenue Obligation shall be treated as one and the same. Notwithstanding any other provision of this Section, in lieu of executing and delivering a new Revenue Obligation for a Revenue Obligation which has been lost, destroyed or stolen and which evidences principal that is then payable, the Trustee may make payment of such Revenue Obligation to the Owner thereof if so instructed by the District. Section 2.10. Book-Entry System. (a) The Revenue Obligations shall be initially executed and delivered as Book-Entry Certificates, and the Revenue Obligations for each stated Principal Payment Date shall be in the form of a separate single fully registered Revenue Obligation (which may be typewritten). Upon initial execution and delivery, the ownership of 298889698.4 13 each Revenue Obligation shall be registered in the registration books maintained by the Trustee in the name of the Nominee, as nominee of the Depository. Payment of principal or interest evidenced by any Book-Entry Certificate registered in the name of the Nominee shall be made on the applicable Interest Payment Date by wire transfer of New York clearing house or equivalent next day funds or by wire transfer of same day funds to the account of the Nominee. Such payments shall be made to the Nominee at the address which is, on the Record Date, shown for the Nominee in the registration books maintained by the Trustee. (b) With respect to Book-Entry Certificates, the District, the Corporation and the Trustee shall have no responsibility or obligation to any Participant or to any Person on behalf of which such a Participant holds an interest in such Book-Entry Certificates. Without limiting the immediately preceding sentence, the District, the Corporation and the Trustee shall have no responsibility or obligation with respect to (i) the accuracy of the records of the Depository, the Nominee or any Participant with respect to any ownership interest in Book-Entry Certificates, (ii) the delivery to any Participant or any other Person, other than an Owner as shown in the registration books maintained by the Trustee, of any notice with respect to Book-Entry Certificates, including any notice of prepayment, (iii) the selection by the Depository and its Participants of the beneficial interests in Book-Entry Certificates to be prepaid in the event Revenue Obligations are prepaid in part, (iv) the payment to any Participant or any other Person, other than an Owner as shown in the registration books maintained by the Trustee, of any amount with respect to principal, premium, if any, or interest evidenced by Book-Entry Certificates, or (v) any consent given or other action taken by the Depository as Owner. (c) The District, the Corporation and the Trustee may treat and consider the Person in whose name each Book-Entry Certificate is registered in the registration books maintained by the Trustee as the absolute Owner of such Book-Entry Certificate for the purpose of payment of principal, prepayment premium, if any, and interest evidenced by such Revenue Obligation, for the purpose of selecting any Revenue Obligations, or portions thereof, to be prepaid, for the purpose of giving notices of prepayment and other matters with respect to such Revenue Obligation, for the purpose of registering transfers with respect to such Revenue Obligation, for the purpose of obtaining any consent or other action to be taken by Owners and for all other purposes whatsoever, and the District, the Corporation and the Trustee shall not be affected by any notice to the contrary. (d) Reserved. (e) The Trustee shall pay all principal, premium, if any, and interest evidenced by the Revenue Obligations to the respective Owner, as shown in the registration books maintained by the Trustee, or his respective attorney duly authorized in writing, and all such payments shall be valid and effective to fully satisfy and discharge the obligations with respect to payment of principal, premium, if any, and interest evidenced by the Revenue Obligations to the extent of the sum or sums so paid. No Person other than an Owner, as shown in the registration books maintained by the Trustee, shall receive a Revenue Obligation evidencing principal, premium, if any, and interest evidenced by the Revenue Obligations. Upon delivery by the Depository to the Owners, the Trustee and the District of written notice to the effect that the Depository has determined to substitute a new nominee in place of the Nominee, and subject to the provisions 298889698.4 14 herein with respect to Record Dates, the word Nominee in this Trust Agreement shall refer to such nominee of the Depository. (f) To qualify the Book-Entry Certificates for the Depository’s book-entry system, the District shall execute and deliver to the Depository a Letter of Representations. The execution and delivery of a Letter of Representations shall not in any way impose upon the Corporation, the District or the Trustee any obligation whatsoever with respect to Persons having interests in such Book-Entry Certificates other than the Owners, as shown on the registration books maintained by the Trustee. Such Letter of Representations may provide the time, form, content and manner of transmission, of notices to the Depository. In addition to the execution and delivery of a Letter of Representations by the District, the District, the Corporation and the Trustee shall take such other actions, not inconsistent with this Trust Agreement, as are reasonably necessary to qualify Book- Entry Certificates for the Depository’s book-entry program. (g) If the District determines that it is in the best interests of the Beneficial Owners that they be able to obtain certificated Revenue Obligations and that such Revenue Obligations should therefore be made available and notifies the Depository and the Trustee of such determination, the Depository will notify the Participants of the availability through the Depository of certificated Revenue Obligations. In such event, the Trustee shall transfer and exchange certificated Revenue Obligations as requested by the Depository and any other Owners in appropriate amounts. In the event (i) the Depository determines not to continue to act as securities depository for Book-Entry Certificates, or (ii) the Depository shall no longer so act and gives notice to the Trustee of such determination, then the District shall discontinue the Book-Entry system with the Depository. If the District determines to replace the Depository with another qualified securities depository, the District shall prepare or direct the preparation of a new single, separate, fully registered Revenue Obligation for each stated Principal Payment Date of such Book-Entry Certificates, registered in the name of such successor or substitute qualified securities depository or its nominee. If the District fails to identify another qualified securities depository to replace the Depository, then the Revenue Obligations shall no longer be restricted to being registered in the registration books maintained by the Trustee in the name of the Nominee, but shall be registered in whatever name or names the Owners transferring or exchanging such Revenue Obligations shall designate, in accordance with the provisions of Sections 2.06 and 2.09 hereof. Whenever the Depository requests the District to do so, the District will cooperate with the Depository in taking appropriate action after reasonable notice (i) to make available one or more separate certificates evidencing the Book-Entry Certificates to any Participant having Book-Entry Certificates credited to its account with the Depository, and (ii) to arrange for another securities depository to maintain custody of certificates evidencing the Book-Entry Certificates. (h) Notwithstanding any other provision of this Trust Agreement to the contrary, if DTC is the sole Owner of the Revenue Obligations, so long as any Book-Entry Certificate is registered in the name of the Nominee, all payments of principal, premium, if any, and interest evidenced by such Revenue Obligation and all notices with respect to such Revenue Obligation shall be made and given, respectively, as provided in the Letter of Representations or as otherwise instructed by the Depository. (i) In connection with any notice or other communication to be provided to Owners pursuant to the Trust Agreement by the District, the Corporation or the Trustee, with respect to 298889698.4 15 any consent or other action to be taken by Owners, the Trustee shall establish a record date for such consent or other action and give the Depository notice of such record date not less than 15 calendar days in advance of such record date to the extent possible. Notice to the Depository shall be given only when DTC is the sole Owner of the Revenue Obligations. ARTICLE III PROCEEDS OF REVENUE OBLIGATIONS Section 3.01. Delivery of Revenue Obligations.

The Trustee may establish a temporary fund or funds to facilitate the foregoing transfers. Section 3.03. Costs of Issuance Fund. The Trustee shall establish and maintain a separate special fund to be held by the Trustee known as the Costs of Issuance Fund. There shall be deposited in the Costs of Issuance Fund on the Closing Date the amount required to be deposited therein pursuant to Section 3.02 hereof. The Trustee shall disburse moneys from the Costs of Issuance Fund on such dates and in such amounts as are necessary to pay Costs of Issuance, in each case upon the Written Request of the District stating the Person to whom payment is to be made, the amount to be paid, the purpose for which the obligation was incurred and that such payment is a proper charge against the Costs of Issuance Fund. On the date that is six months after the Closing Date, the Trustee shall transfer any amounts then remaining in the Costs of Issuance Fund to the Installment Payment Fund. Upon such transfer, the Costs of Issuance Fund shall be closed. 298889698.4 16 ARTICLE IV PREPAYMENT OF REVENUE OBLIGATIONS Section 4.01. Optional Prepayment. The Revenue Obligations maturing on or after February 1, 20___ are subject to optional prepayment prior to their stated Principal Payment Dates, on any date on or after February 1, 20___, in whole or in part, in Authorized Denominations, from and to the extent of prepaid Installment Payments paid pursuant to the Installment Purchase Agreement or from any other source of available funds, any such prepayment to be at a price equal to the principal evidenced by the Revenue Obligations to be prepaid, plus accrued interest evidenced thereby to the date fixed for prepayment, without premium. Section 4.02. Reserved Section 4.03. Selection of Revenue Obligations for Optional Prepayment. Whenever less than all the Outstanding Revenue Obligations are to be prepaid on any one date pursuant to Section 4.01 hereof, with respect to optional prepayment of Revenue Obligations, the Trustee shall select the Revenue Obligations to be prepaid among Revenue Obligations with different Principal Payment Dates as directed in a Written Request of the District. Whenever less than all the Outstanding Revenue Obligations with the same stated Principal Payment Date are to be prepaid on any one date pursuant to Section 4.01 hereof, the Trustee shall select the Revenue Obligations with such Principal Payment Date to be prepaid as directed in a Written Request of the District, or at the discretion of the District by lot in any manner that the Trustee deems fair and appropriate, which decision shall be final and binding upon the District and the Owners. The Trustee shall promptly notify the District in writing of the numbers of the Revenue Obligations so selected for prepayment on such date. For purposes of such selection, any Revenue Obligation may be prepaid in part in Authorized Denominations. Section 4.04. Notice of Prepayment When prepayment of Revenue Obligations is authorized pursuant to Section 4.01, the Trustee shall give notice, at the expense of the District, of the prepayment of the Revenue Obligations. The notice of prepayment shall specify (a) the Revenue Obligations or designated portions thereof (in the case of prepayment of the Revenue Obligations in part but not in whole) which are to be prepaid, (b) the date of prepayment, (c) the place or places where the prepayment will be made, including the name and address of any paying agent, (d) the prepayment price, (e) the CUSIP numbers assigned to the Revenue Obligations to be prepaid, (f) the numbers of the Revenue Obligations to be prepaid in whole or in part and, in the case of any Revenue Obligation to be prepaid in part only, the principal evidenced by such Revenue Obligation to be prepaid, and (g) the interest rate and stated Principal Payment Date of each Revenue Obligation to be prepaid in whole or in part. Such notice of prepayment shall further state that on the specified date there shall become due and payable upon each Revenue Obligation or portion thereof being prepaid the prepayment price and that from and after such date interest evidenced thereby shall cease to accrue and be payable. With respect to any notice of prepayment of Revenue Obligations pursuant to Section 4.01 hereof, unless at the time such notice is given the Revenue Obligations to be prepaid shall be deemed to have been paid within the meaning of Section 10.01 hereof, such notice shall state that such prepayment is conditional upon receipt by the Trustee, on or prior to the date fixed for such prepayment, of moneys sufficient to pay for the prepayment price of the Revenue Obligations to be prepaid, and that if such moneys shall not have 298889698.4 17 been so received said notice shall be of no force and effect and the District shall not be required to prepay such Revenue Obligations. If a notice of prepayment of Revenue Obligations contains such a condition and such moneys are not so received, the prepayment of Revenue Obligations as described in the conditional notice of prepayment shall not be made and the Trustee shall, within a reasonable time after the date on which such prepayment was to occur, give notice to the persons and in the manner in which the notice of prepayment was given, that such moneys were not so received and that there shall be no prepayment of Revenue Obligations pursuant to such notice of prepayment. The Trustee shall, at least 20 but not more than 60 days prior to any prepayment date, give notice of prepayment to the respective Owners of Revenue Obligations designated for prepayment by [first-class mail, postage prepaid], at their addresses appearing on the registration books maintained by the Trustee as of the close of business on the day before such notice of prepayment is given. The actual receipt by the Owner of any notice of such prepayment shall not be a condition precedent to prepayment, and neither failure to receive such notice nor any defect therein shall affect the validity of the proceedings for the prepayment of such Revenue Obligations or the cessation of interest evidenced thereby on the date fixed for prepayment. A certificate by the Trustee that notice of prepayment has been given to Owners as herein provided shall be conclusive as against all parties, and no Owner whose Revenue Obligation is called for prepayment may object thereto or object to the cessation of interest evidenced thereby on the fixed prepayment date by any claim or showing that said Owner failed to actually receive such notice of prepayment. Section 4.05. Partial Prepayment of Revenue Obligations. Upon surrender of any Revenue Obligation prepaid in part only, the Trustee shall execute and deliver to the Owner thereof a new Revenue Obligation or Revenue Obligations evidencing the unprepaid principal with respect to the Revenue Obligation surrendered. Section 4.06. Effect of Prepayment. If notice of prepayment has been duly given as aforesaid and moneys for the payment of the prepayment price of the Revenue Obligations to be prepaid are held by the Trustee, then on the prepayment date designated in such notice, the Revenue Obligations so called for prepayment shall become payable at the prepayment price specified in such notice; and from and after the date so designated, interest evidenced by the Revenue Obligations so called for prepayment shall cease to accrue, such Revenue Obligations shall cease to be entitled to any benefit or security hereunder and the Owners of such Revenue Obligations shall have no rights in respect thereof except to receive payment of the prepayment price thereof. The Trustee shall, upon surrender for payment of any of the Revenue Obligations to be prepaid, pay such Revenue Obligations at the prepayment price thereof, and such moneys shall be pledged to such payment. All Revenue Obligations prepaid pursuant to the provisions of this Article shall be canceled by the Trustee and shall not be redelivered. 298889698.4 18 ARTICLE V ASSIGNMENT AND PLEDGE; FUNDS AND ACCOUNTS Section 5.01.

Moneys in the Prepayment Account shall be used by the Trustee for the purpose of paying the interest, premium, if any, and principal evidenced by the Revenue Obligations to be prepaid pursuant to Section 4.01 hereof. Section 5.03. Reserved. Section 5.04. Investment of Moneys. Except as otherwise provided herein, all moneys in any of the funds or accounts established pursuant to this Trust Agreement shall be invested by the Trustee solely in Permitted Investments, as directed by the District pursuant to a Written Request of the District at least two (2) Business Days prior to the making of such investment.

Without limiting the generality of the foregoing, unless and until the Trustee receives an Opinion of Special Counsel to the effect that failure to comply with such covenant will not adversely affect the exclusion pursuant to section 103(a) of the Code of interest on any Revenue Obligation from the gross income of the owner thereof, the District shall comply with this covenant and each of the specific covenants in this Section. (b) No Private Use or Private Payments.

For purposes of the foregoing covenant, such Gross Proceeds are considered to be “loaned” to a person or entity if: (i) property acquired, constructed or improved with such Gross Proceeds is sold or leased to such person or entity in a transaction that creates a debt for federal income tax purposes; (ii) capacity in or service from such property is committed to such person or entity under a take- or-pay, output or similar contract or arrangement; or (iii) indirect benefits of such Gross Proceeds, or burdens and benefits of ownership of any property acquired, constructed or improved with such Gross Proceeds, are otherwise transferred in a transaction that is the economic equivalent of a loan. For purposes of this covenant, the District will treat any transaction constituting a loan of Gross Proceeds of the Prior Issue as a loan of Gross Proceeds of the Revenue Obligations.

Except as would not cause any Revenue Obligation to become an “arbitrage bond” within the meaning of section 148 of the Code and the Tax Regulations and rulings thereunder, the District will not, at any time prior to the retirement of the final maturity of the Revenue Obligation, directly or indirectly invest Gross Proceeds of the Revenue Obligations in any Investment, if as a result of that investment the yield of any Investment acquired with Gross Proceeds of the Revenue Obligations, whether then held or previously disposed of, would materially exceed the yield of the Revenue Obligations within the meaning of said section 148. (e) Not Federally Guaranteed. Except to the extent such action or failure to act would not pursuant to section 149(b) of the Code and the Tax Regulations and rulings thereunder, adversely affect the exclusion pursuant to section 103(a) of interest on the Revenue Obligations from the gross income of the owners thereof for federal income tax purposes, the District will not take or omit to take any action that would cause any Revenue Obligation to be “federally guaranteed” within the meaning of section 149(b) of the Code and the Tax Regulations and rulings thereunder. (f) Information Report. The District will timely file a Form 8038-G or such other form and in such place as the Secretary of the Treasury may prescribe. (g) Not to Divert Arbitrage Profits. Except to the extent permitted by section 148 of the Code and the Tax Regulations and rulings thereunder, the District will not at any time prior to the retirement of the final maturity of the Revenue Obligations to be retired, enter into any transaction that reduces the amount required to be paid to the United States pursuant to section 148(f) of the Code because such transaction results in a smaller profit or a larger loss than 298889698.4 24 would have resulted if the transaction had been at arm’s length and had the yield on the Revenue Obligations not been relevant to either party. (h) Revenue Obligations Satisfy Section 149(g). The District represents that neither the Prior Issue nor the Revenue Obligations are or will become “hedge bonds” within the meaning of section 149(g) of the Code. Without limitation of the foregoing, with respect to the Prior Issue, (i)(A) on the date of execution and delivery of that issue the District reasonably expected that within the three-year period commencing on such date no less than 85% of the net sale proceeds of that issue would be expended for the governmental purposes thereof, and (B) at no time has more than 50% of the proceeds of that issue been invested in Nonpurpose Investments having a substantially guaranteed yield for a period of four years or more, and with respect to the application of Proceeds of the Revenue Obligations other than for refunding purposes, (ii)(A) the District will not deliver the Revenue Obligations unless on the date of the issuance of the Revenue Obligations it reasonably expects that within the three-year period commencing on such date of issuance at least 85% of such spendable proceeds of the Revenue Obligations will be expended for the governmental purpose of the Revenue Obligations and (B) at no time will more than 50% of such spendable proceeds of the Revenue Obligations be invested in Nonpurpose Investments having a substantially guaranteed yield for a period of four years or more. (i) Elections. The District hereby directs and authorizes any Authorized Representative to make elections permitted or required pursuant to the provisions of the Code or the Tax Regulations, as such Authorized Representative (after consultation with Special Counsel) deems necessary or appropriate in connection with the Revenue Obligations, in the Tax Certificate (as defined below) or similar or other appropriate certificate, form or document. (j) Tax Certificate. The District agrees to execute and deliver in connection with the execution and delivery of the Revenue Obligations a Tax Certificate or similar document containing additional representations and covenants pertaining to the exclusion of interest with respect to the Revenue Obligations from the gross income of the owners thereof for federal income tax purposes (the “Tax Certificate”), which representations and covenants are incorporated as though expressly set forth herein. Section 6.09. Continuing Disclosure. The District will comply with and carry out all of the provisions of the Continuing Disclosure Agreement applicable to it. Notwithstanding any other provision of this Trust Agreement, failure of the District to comply with the Continuing Disclosure Agreement shall not be considered an Event of Default; provided, however, the Trustee at the request of any Participating Underwriter or the Owners of at least 25% aggregate principal amount of Outstanding Revenue Obligations and upon being indemnified to its reasonable satisfaction, shall, or any Owner or Beneficial Owner of Revenue Obligations may take such actions as may be necessary and appropriate to compel performance, including seeking mandate or specific performance by court order. The Trustee is authorized and directed to execute the acceptance and acknowledgement of the Continuing Disclosure Agreement. Section 6.10. Further Assurances. The District will promptly execute and deliver or cause to be executed and delivered all such other and further assurances, documents or instruments and promptly do or cause to be done all such other and further things as may be necessary or 298889698.4 25 reasonably required in order to carry out the purposes and intentions of this Trust Agreement and for preserving and protecting the rights and interests of the Owners. ARTICLE VII DEFAULT AND LIMITATIONS OF LIABILITY Section 7.01. Action upon Event of Default. An Event of Default under the Installment Purchase Agreement shall constitute an Event of Default hereunder and an Event of Default under the Master Agreement shall constitute an Event of Default hereunder. The Trustee may give notice, as assignee of the Corporation, of an Event of Default under the Installment Purchase Agreement to the District, and shall do so if directed to do so by the Owners of not less than 5% of the aggregate principal evidenced by Revenue Obligations then Outstanding. In each and every case during the continuance of an Event of Default, the Trustee may and, at the direction of the Owners of not less than a majority of the aggregate principal evidenced by Revenue Obligations then Outstanding, shall, upon notice in writing to the District and the Corporation (a) exercise any of the remedies granted to the Corporation under the Installment Purchase Agreement, (b) exercise any of the remedies granted to the Trustee under the Master Agreement, and (c) take whatever action at law or in equity may appear necessary or desirable to enforce its rights pursuant to this Trust Agreement, the Installment Purchase Agreement or the Master Agreement or to protect and enforce any of the rights vested in the Trustee or the Owners by this Trust Agreement, the Revenue Obligations, the Installment Purchase Agreement or the Master Agreement, either at law or in equity or in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement or for the enforcement of any other legal or equitable right, including any one or more of the remedies set forth in Section 7.02 hereof. Section 7.02. Other Remedies of the Trustee. Subject to the provisions of Section 7.01 hereof, the Trustee shall have the right: (a) by mandamus or other action or proceeding or suit at law or in equity to enforce its rights against the Corporation or the District or any member, director, officer or employee thereof, and to compel the Corporation or the District or any such member, director, officer or employee to perform or carry out its or his or her duties under law and the agreements and covenants required to be performed by it or him or her contained herein; (b) by suit in equity to enjoin any acts or things which are unlawful or violate the rights of the Trustee; or (c) by suit in equity upon the happening of any Event of Default hereunder to require the Corporation and the District to account as the trustee of an express trust. Section 7.03. Non-Waiver. A waiver of any default or breach of duty or contract by the Trustee or the Owners shall not affect any subsequent default or breach of duty or contract or impair any rights or remedies on any such subsequent default or breach of duty or contract. No delay or omission by the Trustee or the Owners to exercise any right or remedy accruing upon any default or breach of duty or contract shall impair any such right or remedy or shall be construed to be a waiver of any such default or breach of duty or contract or an acquiescence therein, and every 298889698.4 26 right or remedy conferred upon the Trustee or the Owners by law or by this Article may be enforced and exercised from time to time and as often as the Trustee shall deem expedient. If any action, proceeding or suit to enforce any right or to exercise any remedy is abandoned or determined adversely to the Trustee or any Owner, then subject to any adverse determination, the Trustee, such Owner, the Corporation and the District shall be restored to their former positions, rights and remedies as if such action, proceeding or suit had not been brought or taken. Section 7.04. Remedies Not Exclusive. Subject to the provisions of Section 7.01 hereof, no remedy herein conferred upon or reserved to the Trustee is intended to be exclusive of any other remedy, and each such remedy shall be cumulative and shall be in addition to every other remedy given hereunder or now or hereafter existing in law or in equity or by statute or otherwise and may be exercised without exhausting and without regard to any other remedy conferred by any law. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent or subsequent assertion or employment of any other appropriate right or remedy. Section 7.05. Application of Amounts After Default. All damages or other payments received by the Trustee for the enforcement of any rights and powers of the Trustee under this Article shall be deposited into the Installment Payment Fund and as soon as practicable and thereafter applied: (a) to the payment of all amounts due the Trustee under Section 8.03 hereof; (b) unless the unpaid Installment Payments, and the interest thereon, shall have become, and shall remain, immediately due and payable pursuant to the Master Agreement: (i) to the payment of all amounts then due for interest evidenced by the Revenue Obligations, in respect of which, or for the benefit of which, money has been collected (other than Revenue Obligations which have become payable prior to such Event of Default and money for the payment of which is held by the Trustee), ratably without preference or priority of any kind, according to the amounts of interest evidenced by such Revenue Obligations due and payable; and (ii) to the payment of all amounts then due for principal evidenced by the Revenue Obligations, in respect of which, or for the benefit of which, money has been collected (other than Revenue Obligations which have become payable prior to such Event of Default and money for the payment of which is held by the Trustee), ratably without preference or priority of any kind, according to the amounts of principal evidenced by such Revenue Obligations due and payable. (c) if the unpaid Installment Payments, and the interest thereon, shall have become, and shall remain, immediately due and payable pursuant to the Master Agreement, to the payment of all amounts then due for principal and interest evidenced by the Revenue Obligations and, if the amount available therefor shall not be sufficient to pay in full the whole amount so due and unpaid, then to the payment thereof ratably, without preference or priority of principal over interest, or of interest over principal, or of any installment of interest over any other installment of interest, or of any Revenue Obligation over any other Revenue Obligation, to the persons entitled thereto without any discrimination or preference. 298889698.4 27 Section 7.06. Trustee May Enforce Claims Without Possession of Revenue Obligations. All rights of action and claims under this Trust Agreement or the Revenue Obligations may be prosecuted and enforced by the Trustee without the possession of any of the Revenue Obligations or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Owners of the Revenue Obligations in respect of which such judgment has been recovered. Section 7.07. Limitation on Suits. No Owner shall have any right to institute any proceeding, judicial or otherwise, with respect to this Trust Agreement, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless (a) such Owner shall have previously given written notice to the Trustee of a continuing Event of Default hereunder, (b) the Owners of not less than a majority of the aggregate principal evidenced by Revenue Obligations then Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder, (c) such Owner or Owners shall have afforded to the Trustee indemnity reasonably satisfactory to the Trustee against the costs, expenses and liabilities to be incurred in compliance with such request, (d) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity shall have failed to institute any such proceedings, and (e) no direction inconsistent with such written request shall have been given to the Trustee during such 60-day period by the Owners of a majority of the aggregate principal evidenced by Revenue Obligations then Outstanding; it being understood and intended that no one or more Owners of Revenue Obligations shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Trust Agreement to affect, disturb or prejudice the rights of any other Owner of Revenue Obligations, or to obtain or seek to obtain priority or preference over any other Owner or to enforce any right under this Trust Agreement, except in the manner herein provided and for the equal and ratable benefit of all the Owners of Revenue Obligations. Section 7.08. No Liability by the Corporation to the Owners. Except as expressly provided herein, the Corporation shall not have any obligation or liability to the Owners with respect to the payment when due of the Installment Payments, and the interest thereon, by the District, or with respect to the performance by the District of the other agreements and covenants required to be performed by it contained in the Installment Purchase Agreement, the Master Agreement or herein, or with respect to the performance by the Trustee of any right or obligation required to be performed by it contained herein. Section 7.09. No Liability by the District to the Owners. Except for the payment when due of the Installment Payments, and the interest thereon, and the performance of the other agreements and covenants required to be performed by it contained in the Installment Purchase Agreement, the Master Agreement or herein, the District shall not have any obligation or liability to the Owners with respect to this Trust Agreement or the preparation, execution, delivery or transfer of the Revenue Obligations or the disbursement of the Installment Payments, and the interest thereon, by the Trustee to the Owners, or with respect to the performance by the Trustee of any right or obligation required to be performed by it contained herein. 298889698.4 28 Section 7.10. No Liability of the Trustee to the Owners. Except as expressly provided herein, the Trustee shall not have any obligation or liability to the Owners with respect to the payment when due of the Installment Payments, and the interest thereon, by the District, or with respect to the performance by the Corporation or the District of the other agreements and covenants required to be performed by them, respectively contained in the Installment Purchase Agreement or herein. ARTICLE VIII THE TRUSTEE Section 8.01. Employment of the Trustee; Duties. The Corporation and the District hereby appoint and employ the Trustee to receive, deposit and disburse the Installment Payments, and the interest thereon, to register, execute, deliver and transfer the Revenue Obligations and to perform the other functions contained herein, all in the manner provided herein and subject to the conditions and terms hereof. By executing and delivering this Trust Agreement, the Trustee accepts the appointment and employment hereinabove referred to and accepts the rights and obligations of the Trustee provided herein, subject to the conditions and terms hereof. Other than when an Event of Default hereunder has occurred and is continuing, the Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Trust Agreement, and no implied covenants or obligations shall be read into this Trust Agreement against the Trustee. In case an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Trust Agreement, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs. Section 8.02. Removal and Resignation of the Trustee. The Corporation and the District may, by an instrument in writing, remove the Trustee initially a party hereto and any successor thereto unless an Event of Default shall have occurred and then be continuing, and shall remove the Trustee initially a party hereto and any successor thereto if at any time (a) requested to do so by an instrument or concurrent instruments in writing signed by the Owners of a majority of the aggregate principal evidenced by the Revenue Obligations at the time Outstanding (or their attorneys duly authorized in writing), or (b) the Trustee shall cease to be eligible in accordance with the following sentence, and shall appoint a successor Trustee. The Trustee shall be a bank having trust powers or a trust company in good standing in or incorporated under the laws of the United States or any state thereof, having (or if such bank or trust company is a member of a bank holding company system, its parent bank holding company shall have) a combined capital and surplus of at least $75,000,000, and be subject to supervision or examination by federal or state banking authorities. If such bank or trust company publishes a report of condition at least annually, pursuant to law or to the requirements of any supervising or examining authority above referred to, then for the purposes of this Section the combined capital and surplus of such bank or trust company shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. The Trustee may at any time resign by giving written notice of such resignation to the Corporation and the District and by giving notice, by first class mail, postage prepaid, of such resignation to the Owners at their addresses appearing on the registration books maintained by the 298889698.4 29 Trustee. Upon receiving such notice of resignation, the Corporation and the District shall promptly appoint a successor Trustee by an instrument in writing; provided, however, that in the event the District and the Corporation do not appoint a successor Trustee within 30 days following receipt of such notice of resignation, the resigning Trustee may, at the expense of the District, petition the appropriate court having jurisdiction to appoint a successor Trustee. Any resignation or removal of a Trustee and appointment of a successor Trustee shall become effective only upon acceptance of appointment by the successor Trustee. Any successor Trustee appointed under this Trust Agreement shall signify its acceptance of such appointment by executing and delivering to the District and the Corporation and to its predecessor Trustee a written acceptance thereof, and thereupon such successor Trustee, without any further act, deed or conveyance, shall become vested with all the moneys, estates, properties, rights, powers, trusts, duties and obligations of such predecessor Trustee, with like effect as if originally named Trustee herein; but, nevertheless, at the written request of the District or of the successor Trustee, such predecessor Trustee shall execute and deliver any and all instruments of conveyance or further assurance and do such other things as may reasonably be required for more fully and certainly vesting in and confirming to such successor Trustee all the right, title and interest of such predecessor Trustee in and to any property held by it under this Trust Agreement and shall pay over, transfer, assign and deliver to the successor Trustee any money or other property subject to the trusts and conditions herein set forth. Any corporation, association or agency into which the Trustee may be converted or merged, or with which it may be consolidated, or to which it may sell or transfer its corporate trust business and assets as a whole or substantially as a whole, or any corporation or association resulting from any such conversion, sale, merger, consolidation or transfer to which it is a party, provided that such entity meets the combined capital and surplus requirements of this Section, ipso facto, shall be and become successor trustee under this Trust Agreement and vested with all the trusts, powers, discretions, immunities, privileges and all other matters as was its predecessor, without the execution or filing of any instrument or any further act, deed or conveyance on the part of any of the parties hereto, anything herein to the contrary notwithstanding. Section 8.03. Compensation and Indemnification of the Trustee. The District shall from time to time, subject to any written agreement then in effect with the Trustee, pay the Trustee reasonable compensation for all its services rendered hereunder and reimburse the Trustee for all its reasonable advances and expenditures (which shall not include “overhead expenses” except as such expenses are included as a component of the Trustee’s stated annual fees or disclosed transaction fees) hereunder, including but not limited to advances to and reasonable fees and reasonable expenses of accountants, agents, appraisers, consultants or other experts, and counsel not directly employed by the Trustee but an attorney or firm of attorneys retained by the Trustee, employed by it in the exercise and performance of its rights and obligations hereunder; provided, however, that the Trustee shall not have any lien for such compensation or reimbursement against any moneys held by it in any of the funds or accounts established hereunder. The Trustee may take whatever legal actions are lawfully available to it directly against the Corporation or the District. Except as otherwise expressly provided herein, no provision of this Trust Agreement shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers hereunder. 298889698.4 30 The District, to the extent permitted by law, agrees to indemnify and save the Trustee, its directors, officers, employees and agents harmless from and against any costs, expenses, claims and liabilities which it may incur in the exercise and performance of its powers and duties hereunder or any other document related to this Trust Agreement, including but not limited to costs and expenses incurred in defending against any claim or liability, which are not due to its negligence or willful misconduct. The obligations of the District under this Section shall survive the resignation or removal of the Trustee and the termination of this Trust Agreement. Section 8.04. Protection of the Trustee. The Trustee shall be protected and shall incur no liability in acting or proceeding in good faith upon any affidavit, bond, certificate, consent, notice, request, requisition, resolution, statement, waiver or other paper or document which it shall in good faith believe to be genuine and to have been adopted, executed or delivered by the proper party or pursuant to any of the provisions hereof, and the Trustee shall be under no duty to make any investigation or inquiry as to any statements contained or matters referred to in any such instrument, but may accept and rely upon the same as conclusive evidence of the truth and accuracy of such statements. The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Trust Agreement at the request or direction of any of the Owners of the Revenue Obligations pursuant to this Trust Agreement, unless such Owners shall have offered to the Trustee security or indemnity, reasonably satisfactory to the Trustee, against the reasonable costs, expenses and liabilities which might be incurred by it in compliance with such request or direction. The Trustee may consult with counsel, who may be counsel to the Corporation or the District, with regard to legal questions, and the opinion of such counsel shall be full and complete authorization and protection in respect to any action taken or suffered by it hereunder in good faith in accordance therewith. The Trustee shall not be responsible for the sufficiency of the Revenue Obligations or the Installment Purchase Agreement, or of the assignment made to it hereunder, or for statements made in the preliminary or final official statement relating to the Revenue Obligations. The Trustee shall not be required to take notice or be deemed to have notice of any default or Event of Default hereunder, except failure of any of the payments to be made to the Trustee required to be made hereunder or under the Installment Purchase Agreement, unless the Trustee shall be specifically notified in writing of such default or Event of Default by the District, the Corporation or the Owners of not less than 5% of the aggregate principal evidenced by the Revenue Obligations then Outstanding. Whenever in the administration of its rights and obligations hereunder the Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking or suffering any action hereunder, such matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively proved and established by a Written Certificate of the District or a Written Certificate of the Corporation, and such Written Certificate shall be full warrant to the Trustee for any action taken or suffered under the provisions hereof upon the faith thereof, but in its discretion the Trustee may, in lieu thereof, accept other evidence of such matter or may require such additional evidence as it deems reasonable. The Trustee may buy, sell, own, hold and deal in any of the Revenue Obligations and may join in any action which any Owner may be entitled to take with like effect as if the Trustee were 298889698.4 31 not a party hereto. The Trustee, either as principal or agent, may also engage in or be interested in any financial or other transaction with the Corporation or the District, and may act as agent, depository or trustee for any committee or body of Owners or of owners of obligations of the Corporation or the District as freely as if it were not the Trustee hereunder. The Trustee may, to the extent reasonably necessary, execute any of the trusts or powers hereof and perform any rights and obligations required of it hereunder by or through agents, attorneys or receivers, and shall be entitled to advice of counsel concerning all matters of trust and its rights and obligations hereunder, and the Trustee shall not be answerable for the negligence or misconduct of any such agent, attorney or receiver selected by it with reasonable care; provided, however, that in the event of any negligence or misconduct of any such attorney, agent or receiver, the Trustee shall diligently pursue all remedies of the Trustee against such agent, attorney or receiver. The Trustee shall not be liable for any error of judgment made by it in good faith unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts. The Trustee shall not be answerable for the exercise of any trusts or powers hereunder or for anything whatsoever in connection with the funds established hereunder, except only for its own willful misconduct, negligence or breach of an obligation hereunder. The Trustee may, on behalf of the Owners, intervene in any judicial proceeding to which the Corporation or the District is a party and which, in the opinion of the Trustee and its counsel, affects the Revenue Obligations or the security therefor, and shall do so if requested in writing by the Owners of at least 5% of the aggregate principal evidenced by Revenue Obligations then Outstanding, provided the Trustee shall have no duty to take such action unless it has been indemnified to its reasonable satisfaction against all risk or liability arising from such action. The Trustee will not be considered in breach of or in default in its obligations hereunder or progress in respect thereto in the event of delay in the performance of such obligations due to unforeseeable causes beyond its control and without its fault or negligence, including, but not limited to, acts of God or of the public enemy or terrorists, acts of a government, acts of the other parties, fires, floods, epidemics, quarantine restrictions, strikes, freight embargoes, earthquakes, explosion, mob violence, riot, inability to procure or general sabotage or rationing of labor, equipment, facilities, sources of energy, material or supplies in the open market, litigation or arbitration involving a party or others relating to zoning or other governmental action or inaction pertaining to any project refinanced with the proceeds of the Revenue Obligations, malicious mischief, condemnation, and unusually severe weather or any similar event and/or occurrences beyond the control of the Trustee. In no event shall the Trustee be responsible or liable for special, indirect, consequential, punitive or incidental loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action. The Trustee agrees to accept and act upon instructions or directions pursuant to this Trust Agreement sent by unsecured e-mail, facsimile transmission or other similar unsecured electronic 298889698.4 32 methods; provided, however, that the Trustee shall have received an incumbency certificate listing persons designated to give such instructions or directions and containing specimen signatures of such designated persons, which such incumbency certificate shall be amended and replaced whenever a person is to be added or deleted from the listing. If the Corporation or the District elects to give the Trustee e-mail or facsimile instructions (or instructions by a similar electronic method) and the Trustee in its discretion elects to act upon such instructions, the Trustee’s understanding of such instructions shall be deemed controlling. The Trustee shall not be liable for any losses, costs or expenses arising directly or indirectly from the Trustee’s reliance upon and compliance with such instructions notwithstanding such instructions conflict or are inconsistent with a subsequent written instruction. The Corporation or the District agree to assume all risks arising out of the use of such electronic methods to submit instructions and directions to the Trustee, including, without limitation, the risk of the Trustee acting on unauthorized instructions, and the risk of interception and misuse by third parties. ARTICLE IX AMENDMENT OF OR SUPPLEMENT TO TRUST AGREEMENT Section 9.01. Amendment or Supplement. This Trust Agreement and the rights and obligations of the Corporation, the District, the Owners and the Trustee hereunder may be amended or supplemented at any time by an amendment hereof or supplement hereto which shall become binding when the prior written consents of the Owners of a majority of the aggregate principal evidenced by the Revenue Obligations then Outstanding, exclusive of Revenue Obligations disqualified as provided in Section 9.02 hereof, are filed with the Trustee. No such amendment or supplement shall (i) extend the stated Principal Payment Date of any Revenue Obligation or reduce the rate of interest evidenced thereby or extend the time of payment of such interest or reduce the amount of principal evidenced thereby or change the prepayment terms and provisions or the provisions regarding delivery of notice of prepayment without the prior written consent of the Owner of each Revenue Obligation so affected, (ii) reduce the percentage of Owners whose consent is required for the execution of any amendment hereof or supplement hereto without the prior written consent of the Owners of all Revenue Obligations then Outstanding, (iii) modify any of the rights or obligations of the Trustee without the prior written consent of the Trustee, or (iv) amend this Section without the prior written consent of the Owners of all Revenue Obligations then Outstanding. (a) This Trust Agreement and the rights and obligations of the Corporation, the District, the Owners and the Trustee hereunder may also be amended or supplemented at any time by an amendment hereof or supplement hereto which shall become binding upon execution, without the written consents of any Owners, but only to the extent permitted by law and only for any one or more of the following purposes: (i) to add to the agreements, conditions, covenants and terms required by the Corporation or the District to be observed or performed herein other agreements, conditions, covenants and terms thereafter to be observed or performed by the Corporation or the District, or to surrender any right or power reserved herein to or conferred herein on the Corporation or the District; 298889698.4 33 (ii) to make such provisions for the purpose of curing any ambiguity or of correcting, curing or supplementing any defective provision contained herein or in regard to questions arising hereunder which the Corporation or the District may deem desirable or necessary and not inconsistent herewith; (iii) to make such additions, deletions or modifications as may be necessary or appropriate to assure the exclusion from gross income for federal income tax purposes of interest evidenced by the Revenue Obligations; or (iv) for any other reason, provided such amendment or supplement does not adversely affect the rights or interests of the Owners. Section 9.02. Disqualified Revenue Obligations. Revenue Obligations owned or held by or for the account of the District (but excluding Revenue Obligations held in any pension or retirement fund of the District) shall not be deemed Outstanding for the purpose of any consent or other action or any calculation of Outstanding Revenue Obligations provided in this Article, and shall not be entitled to consent to or take any other action provided in this Article, and the Trustee may adopt appropriate regulations to require each Owner, before his consent provided for herein shall be deemed effective, to reveal if the Revenue Obligations as to which such consent is given are disqualified as provided in this Section. Section 9.03. Endorsement or Replacement of Revenue Obligations After Amendment or Supplement. After the effective date of any action taken as hereinabove provided in this Article, the Trustee may determine that the Revenue Obligations may bear a notation by endorsement in form approved by the Trustee as to such action, and in that case upon demand of the Owner of any Outstanding Revenue Obligation and presentation of such Revenue Obligation for such purpose at the Principal Office a suitable notation as to such action shall be made on such Revenue Obligation. If the Trustee shall receive an Opinion of Counsel advising that new Revenue Obligations modified to conform to such action are necessary, modified Revenue Obligations shall be prepared, and in that case upon demand of the Owner of any Outstanding Revenue Obligations such new Revenue Obligations shall be exchanged at the Principal Office without cost to each Owner for Revenue Obligations then Outstanding upon surrender of such Outstanding Revenue Obligations. Section 9.04. Amendment by Mutual Consent. The provisions of this Article shall not prevent any Owner from accepting any amendment as to the particular Revenue Obligations owned by such Owner, provided that due notation thereof is made on such Revenue Obligations. ARTICLE X DEFEASANCE Section 10.01. Discharge of Revenue Obligations and Trust Agreement. (a) If the Trustee shall pay or cause to be paid or there shall otherwise be paid (i) to the Owners of all Outstanding Revenue Obligations the interest and principal evidenced thereby at the times and in the manner stipulated herein and therein, and (ii) all other amounts due hereunder and under the Installment Purchase Agreement, then such Owners shall cease to be entitled to the pledge of and 298889698.4 34 lien on the amounts on deposit in the funds and accounts established hereunder, as provided herein, and all agreements and covenants of the Corporation, the District, and the Trustee to such Owners hereunder shall thereupon cease, terminate and become void and shall be discharged and satisfied. (b) Any Outstanding Revenue Obligation shall be deemed to have been paid within the meaning and with the effect expressed in this Section when the whole amount of the principal, premium, if any, and interest evidenced by such Revenue Obligation shall have been paid or when (i) in case said Revenue Obligation or portion thereof has been selected for prepayment in accordance with Section 4.03 hereof prior to its stated Principal Payment Date, the District shall have given to the Trustee irrevocable instructions to give, in accordance with the provisions of Section 4.03 hereof, notice of prepayment of such Revenue Obligation, or portion thereof, (ii) there shall be on deposit with the Trustee, moneys, or Government Obligations, or any combination thereof, the principal of and the interest on which when due, and without any reinvestment thereof, will provide moneys which shall be sufficient to pay when due the principal, premium, if any, and interest evidenced by such Revenue Obligation and due and to become due on or prior to the prepayment date or its stated Principal Payment Date, as the case may be, and (iii) in the event the stated Principal Payment Date of such Revenue Obligation will not occur, and said Revenue Obligation is not to be prepaid, within the next succeeding 60 days, the District shall have given the Trustee irrevocable instructions to give notice, as soon as practicable in the same manner as a notice of prepayment given pursuant to Section 4.03 hereof, to the Owner of such Revenue Obligation, or portion thereof, stating that the deposit of moneys or Government Obligations required by clause (ii) of this subsection has been made with the Trustee and that said Revenue Obligation, or portion thereof, is deemed to have been paid in accordance with this Section and stating such Principal Payment Date or prepayment date upon which moneys are to be available for the payment of the principal, premium, if any, and interest evidenced by said Revenue Obligation, or portion thereof.

This Revenue Obligation is one of the duly authorized Orange County Sanitation District Wastewater Refunding Revenue Obligations, Series 2025A (the “Revenue Obligations”) evidencing principal in the aggregate amount of $__________, executed pursuant to the terms of the Trust Agreement. The Revenue Obligations evidence direct, fractional undivided interests in the Installment Payments, and the interest thereon, payable under the Installment Purchase Agreement. The Revenue Obligations are executed and delivered to refinance certain improvements to the wastewater collection, treatment and disposal facilities of the District (the “Wastewater System”) and to pay the costs of issuance incurred in connection therewith and to pay certain other related costs. The Installment Payments, and the interest thereon, are to be paid by the District pursuant to the Installment Purchase Agreement in consideration for the purchase of certain improvements to the Wastewater System and for the other agreements and obligations undertaken by the Corporation under the Installment Purchase Agreement and the Trust Agreement. The income and revenue received by the District from the operation of the Wastewater System remaining after the payment of maintenance and operation or ownership costs of the Wastewater System (as more fully described in the Installment Purchase Agreement, the “Net Revenues”) are, pursuant to the Master Agreement, pledged to the payment of the Senior Obligations and Reimbursement Obligations with respect to Senior Obligations (as such terms are defined in the Master Agreement). The Installment Purchase Agreement constitutes a Senior Obligation and, as such, shall be subject to the provisions of the Master Agreement, and shall be afforded all of the advantages, benefits, interests and security afforded Senior Obligations pursuant to the Master Agreement. The Installment Purchase Agreement is payable on a parity with the other existing Senior Obligations. The District may at any time incur Senior Obligations in addition to existing Senior Obligations and the Installment Purchase Agreement payable from Net Revenues as provided in the Master Agreement on a parity with all other Senior Obligations theretofore incurred, but only subject to the conditions and upon compliance with the procedures set forth in the Master Agreement. The District is not required to advance any moneys derived from any source of income other than Net Revenues and the other funds provided in the Installment Purchase Agreement for the payment of the Installment Payments, and the interest thereon, and other payments required to be made by it under the Installment Purchase Agreement, or for the performance of any agreements or covenants required to be performed by it contained therein. The obligation of the District to pay the Installment Payments, and the interest thereon, and other payments required to be made by it under the Installment Purchase Agreement is a special obligation of the District payable, in the manner provided in the Installment Purchase Agreement, solely from such Net Revenues and other funds provided for therein, and does not constitute a debt of the District or of the State of 298889698.4 A-3 California, or of any political subdivision thereof, in contravention of any constitutional or statutory debt limitation or restriction. Reference is hereby made to the Master Agreement, the Installment Purchase Agreement and to the Trust Agreement and any and all amendments thereof and supplements thereto for a description of the terms under which the District’s obligation to pay the Installment Payments, and the interest thereon, is incurred, the Revenue Obligations are executed and delivered, the provisions with regard to the nature and extent of the Net Revenues, and the rights of the Owners of the Revenue Obligations. All of the terms of the Master Agreement, the Installment Purchase Agreement and the Trust Agreement are hereby incorporated herein. The Trust Agreement constitutes a contract among the District, the Corporation and the Trustee for the benefit of the Owners of the Revenue Obligations, to all the provisions of which the Owner of this Revenue Obligation, by acceptance hereof, agrees and consents. The Registered Owner of this Revenue Obligation is entitled to receive, subject to the terms of the Trust Agreement and any right of prepayment as provided herein or therein, on the Principal Payment Date set forth above, upon presentation and surrender of this Revenue Obligation at the principal corporate trust office of the Trustee in St. Paul, Minnesota (the “Principal Office”), the Principal Amount specified above, evidencing the Owner’s interest in the Installment Payments coming due on the Principal Payment Date, and to receive on February 1 and August 1 of each year, commencing on February 1, 2026 (each an “Interest Payment Date”), interest accrued thereon at the Interest Rate specified above, computed on the basis of a 360-day year consisting of twelve 30-day months, until said Principal Amount is paid in full, evidencing the Registered Owner’s interest in the interest evidenced by the Installment Payments coming due on each of said dates. This Revenue Obligation shall evidence interest from the Interest Payment Date next preceding its date of execution to which interest has been paid in full, unless such date of execution shall be after the 15th day of the month next preceding an Interest Payment Date, whether or not such day is a business day (each such date, a “Record Date”), and on or prior to the following Interest Payment Date, in which case this Revenue Obligation shall evidence interest from such Interest Payment Date, or unless such date of execution shall be on or prior to the first Record Date, in which case this Revenue Obligation shall evidence interest from the Dated Date specified above. Notwithstanding the foregoing, if, as shown by the records of the Trustee, interest evidenced by the Revenue Obligations shall be in default, this Revenue Obligation shall evidence interest from the last Interest Payment Date to which interest has been paid in full or duly provided for. Payments of interest evidenced by the Revenue Obligations shall be made to the Owners thereof (as determined at the close of business on the Record Date next preceding the related Interest Payment Date) by check or draft of the Trustee mailed to the address of each such Owner as it appears on the registration books maintained by the Trustee pursuant to the Trust Agreement, or to such other address as may be furnished in writing to the Trustee by such Owner.

The Trustee may treat the Registered Owner hereof as the absolute owner hereof for all purposes, whether or not the principal or interest evidenced by this Revenue Obligation shall be overdue, and the Trustee shall not be affected by any knowledge or notice to the contrary; and payment of the principal and interest evidenced by this Revenue Obligation shall be made only to such Registered Owner, which payments shall be valid and effectual to satisfy and discharge the liability evidenced by this Revenue Obligation to the extent of the sum or sums so paid. The Revenue Obligations are subject to prepayment prior to their stated Principal Payment Dates in accordance with the Trust Agreement. To the extent and in the manner permitted by the terms of the Trust Agreement, the Trust Agreement and the rights and obligations of the Corporation, the District, the Owners and the Trustee under the Trust Agreement may be amended or supplemented at any time by an amendment or supplement thereto which shall become binding when the prior written consents of the Owners of a majority of the aggregate principal evidenced by the Revenue Obligations then outstanding, exclusive of Revenue Obligations disqualified as provided under the Trust Agreement, are filed with the Trustee. No such supplement or amendment shall (a) extend the stated Principal Payment Date of any Revenue Obligation or reduce the rate of interest evidenced thereby or extend the time of payment of such interest or reduce the amount of principal evidenced thereby or change the prepayment terms and provisions or the provisions regarding delivery of notice of prepayment without the prior written consent of the Owner of each Revenue Obligation so affected, (b) reduce the percentage of Owners whose consent is required for the execution of any amendment of or supplement to the Trust Agreement without the prior written consent of the Owners of all Revenue Obligations then outstanding, (c) modify any of the rights or obligations of the Trustee without the prior written consent of the Trustee, or (d) amend the amendment provisions of the Trust Agreement without the prior written consent of the Owners of all Revenue Obligations then outstanding. To the extent and in the manner permitted by the terms of the Trust Agreement, the Trust Agreement and the rights and obligations of the Corporation, the District, the Owners and the Trustee under the Trust Agreement may also be amended or supplemented at any time by an amendment or supplement thereto which shall become binding upon execution, without the written 298889698.4 A-5 consents of any Owners, but only to the extent permitted by law and only (a) to add to the agreements, conditions, covenants and terms required by the Corporation or the District to be observed or performed under the Trust Agreement other agreements, conditions, covenants and terms thereafter to be observed or performed by the Corporation or the District, or to surrender any right or power reserved therein to or conferred therein on the Corporation or the District, and which in either case shall not adversely affect the rights or interests of the Owners, (b) to make such provisions for the purpose of curing any ambiguity or of correcting, curing or supplementing any defective provision contained in the Trust Agreement or in regard to questions arising thereunder which the Corporation or the District may deem desirable or necessary and not inconsistent therewith or (c) for any other reason, provided such amendment or supplement does not adversely affect the rights or interests of the Owners.

Such delivery of and payment for the Revenue Obligations is referred to herein as the “Closing.” The Revenue Obligations shall be made available for inspection by the Underwriters at least one business day before the Closing. SECTION 9: Establishment of the Issue Price. (a) The Representative, on behalf of the Underwriters, agrees to assist the District in establishing the issue price of the Revenue Obligations and shall execute and deliver to the District at Closing an “issue price” or similar certificate, together with the supporting pricing wires or equivalent communications, substantially in the form attached hereto as Exhibit C, with such modifications as may be appropriate or necessary, in the reasonable judgment of the 4 299309682.2 Representative, the District and Special Counsel, to accurately reflect, as applicable, the sales price or prices or the initial offering price or prices to the public of the Revenue Obligations. (b) [Except as otherwise set forth in Schedule A to Exhibit C attached hereto,] the District will treat the first price at which 10% of each maturity of the Revenue Obligations (the “10% test”) is sold to the public as the issue price of that maturity (if different interest rates apply within a maturity, each separate CUSIP number within that maturity will be subject to the 10% test). At or promptly after the execution of this Purchase Agreement, the Representative shall report to the District the price or prices at which the Underwriters have sold to the public each maturity of Revenue Obligations. [If at that time the 10% test has not been satisfied as to any maturity of the Revenue Obligations, the Representative agrees to promptly report to the District the prices at which Revenue Obligations of that maturity have been sold by the Underwriters to the public. That reporting obligation shall continue, whether or not the Closing Date has occurred, until either (i) all Revenue Obligations of that maturity have been sold or (ii) the 10% test has been satisfied as to the Revenue Obligations of that maturity, provided that, the Underwriters’ reporting obligation after the Closing Date may be at reasonable periodic intervals or otherwise upon request of the Representative, the District or Special Counsel.] For purposes of this Section, if Revenue Obligations mature on the same date but have different interest rates, each separate CUSIP number within that maturity will be treated as a separate maturity of the Revenue Obligations. (c) The Representative confirms that the Underwriters have offered the Revenue Obligations to the public on or before the date of this Purchase Agreement at the offering price or prices (the “initial offering price”), or at the corresponding yield or yields, set forth in Schedule A to Exhibit C attached hereto, except as otherwise set forth therein. Schedule A to Exhibit C also sets forth, as of the date of this Purchase Agreement, the maturities, if any, of the Revenue Obligations for which the 10% test has not been satisfied and for which the District and the Representative, on behalf of the Underwriters, agrees that the restrictions set forth in the next sentence shall apply, which will allow the District to treat the initial offering price to the public of each such maturity as of the sale date as the issue price of that maturity (the “hold-the-offering- price rule”). So long as the hold-the-offering-price rule remains applicable to any maturity of the Revenue Obligations, the Underwriters will neither offer nor sell unsold Revenue Obligations of that maturity to any person at a price that is higher than the initial offering price to the public during the period starting on the sale date and ending on the earlier of the following: (1) the close of the fifth (5th) business day after the sale date; or (2) the date on which the Underwriters have sold at least 10% of that maturity of the Revenue Obligations to the public at a price that is no higher than the initial offering price to the public. The Representative will advise the District promptly after the close of the fifth (5th) business day after the sale date whether it has sold 10% of that maturity of the Revenue Obligations to the public at a price that is no higher than the initial offering price to the public. (d) The Representative confirms that: 5 299309682.2 (i) any agreement among underwriters, any selling group agreement and each third-party distribution agreement (to which the Representative is a party) relating to the initial sale of the Revenue Obligations to the public, together with the related pricing wires, contains or will contain language obligating each underwriter, each dealer who is a member of the selling group and each broker-dealer that is a party to such third-party distribution agreement, as applicable: (A)(1) to report the prices at which it sells to the public the unsold Revenue Obligations of each maturity allocated to it, whether or not the Closing Date has occurred, until either all Revenue Obligations of that maturity allocated to it have been sold or it is notified by the Representative that the 10% test has been satisfied as to the Revenue Obligations of that maturity, provided that, the reporting obligation after the Closing Date may be at reasonable periodic intervals or otherwise upon request of the Representative, and (2) to comply with the hold-the- offering-price rule, if applicable, if and for so long as directed by the Representative and as set forth in the related pricing wires, (B) to promptly notify the Representative of any sales of Revenue Obligations that, to its knowledge, are made to a purchaser who is a related party to an underwriter participating in the initial sale of the Revenue Obligations to the public (each such term being used as defined below), and (C) to acknowledge that, unless otherwise advised by the underwriter, dealer or broker-dealer, the Representative shall assume that each order submitted by the underwriter, dealer or broker-dealer is a sale to the public. (ii) any agreement among underwriters or selling group agreement relating to the initial sale of the Revenue Obligations to the public, together with the related pricing wires, contains or will contain language obligating each underwriter or dealer that is a party to a third-party distribution agreement to be employed in connection with the initial sale of the Revenue Obligations to the public to require each broker-dealer that is a party to such third-party distribution agreement to (A) report the prices at which it sells to the public the unsold Revenue Obligations of each maturity allocated to it, whether or not the Closing Date has occurred, until either all Revenue Obligations of that maturity allocated to it have been sold or it is notified by the Representative or such underwriter or dealer that the 10% test has been satisfied as to the Revenue Obligations of that maturity, provided that, the reporting obligation after the Closing Date may be at reasonable periodic intervals or otherwise upon request of the Representative or such underwriter or dealer, and (B) comply with the hold-the-offering-price rule, if applicable, if and for so long as directed by the Representative or the underwriter or the dealer and as set forth in the related pricing wires. (e) The District acknowledges that, in making the representations set forth in this section, the Representative will rely on (i) the agreement of each underwriter to comply with the requirements for establishing issue price of the Revenue Obligations, including, but not limited to, its agreement to comply with the hold-the-offering-price rule, if applicable to the Revenue Obligations, as set forth in an agreement among underwriters and the related pricing wires, (ii) in the event a selling group has been created in connection with the initial sale of the Revenue 6 299309682.2 Obligations to the public, the agreement of each dealer who is a member of the selling group to comply with the requirements for establishing issue price of the Revenue Obligations, including, but not limited to, its agreement to comply with the hold-the-offering-price rule, if applicable to the Revenue Obligations, as set forth in a selling group agreement and the related pricing wires, and (iii) in the event that an underwriter or dealer who is a member of the selling group is a party to a third-party distribution agreement that was employed in connection with the initial sale of the Revenue Obligations to the public, the agreement of each broker-dealer that is a party to such agreement to comply with the requirements for establishing issue price of the Revenue Obligations, including, but not limited to, its agreement to comply with the hold-the-offering-price rule, if applicable to the Revenue Obligations, as set forth in the third-party distribution agreement and the related pricing wires. The District further acknowledges that each underwriter shall be solely liable for its failure to comply with its agreement regarding the requirements for establishing issue price of the Revenue Obligations, including, but not limited to, its agreement to comply with the hold-the-offering-price rule, if applicable to the Revenue Obligations, and that no underwriter shall be liable for the failure of any other underwriter, or of any dealer who is a member of a selling group, or of any broker-dealer that is a party to a third-party distribution agreement, to comply with its corresponding agreement to comply with the requirements for establishing issue price of the Revenue Obligations, including, but not limited to, its agreement to comply with the hold-the- offering-price rule, if applicable to the Revenue Obligations. (f) The Representative acknowledges that sales of any Revenue Obligations to any person that is a related party to an underwriter participating in the initial sale of the Revenue Obligations to the public (each such term being used as defined below) shall not constitute sales to the public for purposes of this section. Further, for purposes of this section: (i) “public” means any person other than an underwriter or a related party to an underwriter, (ii) “underwriter” means (A) any person that agrees pursuant to a written contract with the District (or with the lead underwriter to form an underwriting syndicate) to participate in the initial sale of the Revenue Obligations to the public and (B) any person that agrees pursuant to a written contract directly or indirectly with a person described in clause (A) to participate in the initial sale of the Revenue Obligations to the public (including a member of a selling group or a party to a third-party distribution agreement participating in the initial sale of the Revenue Obligations to the public), (iii) a purchaser of any of the Revenue Obligations is a “related party” to an underwriter if the underwriter and the purchaser are subject, directly or indirectly, to (A) more than 50% common ownership of the voting power or the total value of their stock, if both entities are corporations (including direct ownership by one corporation of another), (B) more than 50% common ownership of their capital interests or profits interests, if both entities are partnerships (including direct ownership by one partnership of another), or (C) more than 50% common ownership of the value of the outstanding stock of the corporation or the capital interests or profit interests of the partnership, as applicable, if one entity is a corporation and the other entity is a partnership (including direct ownership of the applicable stock or interests by one entity of the other), and 7 299309682.2 (iv) “sale date” means the date of execution of this Purchase Agreement by all parties.

Whenever the Escrow Agent shall deem it necessary or desirable that a matter be proved or established prior to taking, suffering, or omitting any action under this Escrow Agreement, such matter (except the matters set forth herein as specifically requiring a certificate of a nationally recognized firm of independent certified public accountants or an opinion of counsel of recognized standing in the field of law relating to municipal bonds) may be deemed to be conclusively established by a written certification of the District. The Escrow Agent shall furnish the District periodic cash transaction statements which include detail for all investment transactions effected by the Escrow Agent or brokers selected by the District. Upon the District’s election, such statements will be delivered via the Escrow Agent’s online service and upon electing such service, paper statements will be provided only upon request.

Severability. If any one or more of the covenants or agreements provided in this Escrow Agreement on the part of the District or the Escrow Agent to be performed should be determined by a court of competent jurisdiction to be contrary to law, such covenants or agreements shall be null and void and shall be deemed separate from the remaining covenants and agreements herein contained and shall in no way affect the validity of the remaining provisions of this Escrow Agreement. Section 15. Counterparts. This Escrow Agreement may be executed in several counterparts, all or any of which shall be regarded for all purposes as an original but all of which shall constitute and be but one and the same instrument.

Each bidder must have obtained and reviewed the Preliminary Official Statement prior to bidding for the Revenue Obligations. This Official Notice Inviting Bids, including all exhibits and attachments, contains certain information for quick reference only, is not a summary of the issue and governs only the terms of the sale of, bidding for and closing procedures with respect to the Revenue Obligations. Bidders must read the entire Preliminary Official Statement to obtain information essential to making an informed investment decision. * Preliminary, subject to change. 298913430.3 2 Pursuant to the Master Agreement for District Obligations, dated as of August 1, 2000 (the “Master Agreement”), by and between the District and the Corporation, the District has established and declared the conditions and terms upon which obligations such as the Installment Purchase Agreement, and the Installment Payments and the interest thereon, will be incurred and secured. Installment Payments under the Installment Purchase Agreement are payable solely from Net Revenues, as provided in the Master Agreement and the Installment Purchase Agreement, consisting primarily of all income and revenue received by the District from the operation or ownership of the Wastewater System of the District (the “Wastewater System”) remaining after payment of Maintenance and Operation Costs. The Issue The proceeds from the sale of the Revenue Obligations, together with other funds of the District, will be used to (i) prepay [all/a portion] of the District’s Wastewater Refunding Revenue Obligations, Series 2016A outstanding in the aggregate principal amount of $[___] and (ii) pay the costs incurred in connection with the execution and delivery of the Revenue Obligations. The Revenue Obligations are to be executed and delivered pursuant to a Trust Agreement, dated as of [November 1], 2025 (the “Trust Agreement”), by and among the District, the Corporation and U.S. Bank Trust Company, National Association, as trustee (the “Trustee”). Capitalized terms not defined herein shall have the same definitions as used in the Trust Agreement or the Master Agreement. Authorization On [September 24], 2025, the District and the Corporation authorized the execution and delivery of the Installment Purchase Agreement, the Trust Agreement and the Revenue Obligations. Outstanding Senior Obligations The District has outstanding Senior Obligations payable on parity with the Installment Payments under the Installment Purchase Agreement. The term “Existing Senior Obligations” as used in the Preliminary Official Statement refers to the 2010A Installment Purchase Agreement, the 2010C Installment Purchase Agreement, the 2014A Installment Purchase Agreement, the 2016A Installment Purchase Agreement, the 2017A Installment Purchase Agreement, 2021A Installment Purchase Agreement, the 2022A Installment Purchase Agreement and the 2024A Installment Purchase Agreement. Security and Source of Payments The Revenue Obligations are certificates of participation which evidence direct, undivided fractional interests in the Installment Payments, and the interest thereon, paid by the District pursuant to the Installment Purchase Agreement. The obligation of the District to pay the Installment Payments and the interest thereon and other payments required to be made by it under the Installment Purchase Agreement is a special obligation of the District payable, in the manner provided under the Installment Purchase Agreement, solely from Net Revenues and other funds as provided in the Installment Purchase Agreement. Net Revenues generally consist of all income and revenue received by the District from the operation or ownership of the Wastewater System remaining after payment of Maintenance and Operation Costs, all as further provided in the Master Agreement. The District’s obligation to make Installment Payments from Net Revenues is on parity with the District’s obligation to make payments with respect to its other outstanding obligations described as Senior Obligations and all Reimbursement Obligations, if any, with respect to Senior Obligations, as provided in the Master Agreement. The Installment Purchase Agreement constitutes a Senior Obligation and is subject to the provisions of the Master Agreement and is afforded all of the advantages, benefits, interests and 298913430.3 3 security for Senior Obligations pursuant to the Master Agreement. Pursuant to the Master Agreement, the District pledges all Net Revenues to the payment of the Senior Obligations and Reimbursement Obligations with respect to Senior Obligations, and the Net Revenues will not be used for any other purpose while any of the Senior Obligations or Reimbursement Obligations with respect to Senior Obligations remain unpaid; provided, however, that out of the Net Revenues there may be apportioned such sums for such purposes as are expressly permitted by the Master Agreement. This pledge constitutes a first lien on the Net Revenues for the payment of the Senior Obligations and Reimbursement Obligations with respect to Senior Obligations. The term Senior Obligations, generally means all revenue bonds or notes (including bond anticipation notes and commercial paper) of the District authorized, executed, issued and delivered under and pursuant to applicable law, the Installment Purchase Agreement and all other contracts (including financial contracts) or leases of the District authorized and executed by the District under and pursuant to applicable law, the installment, lease or other payments which are, in accordance with the provisions of the Master Agreement, payable from Net Revenues on parity with the payments under the Master Agreement. The District may at any time incur Subordinate Obligations; provided, however, that prior to incurring such Subordinate Obligations, the District will have determined that the incurrence thereof will not materially adversely affect the District’s ability to comply with the requirements of the Master Agreement. The District may at any time incur Reimbursement Obligations with respect to Subordinate Obligations. Currently, there are no Subordinate Obligations outstanding. For a description of the District’s outstanding Senior Obligations, see “FINANCIAL OBLIGATIONS — Existing Indebtedness” in the Preliminary Official Statement. The District may, in connection with the incurrence of Subordinate Obligations, pledge Net Revenues to the payment of Subordinate Obligations and Reimbursement Obligations with respect to Subordinate Obligations; provided, however, that such pledge, and any lien created thereby, shall be junior and subordinate to the pledge of, and lien on, Net Revenues for the payment of Senior Obligations and Reimbursement Obligations with respect to Senior Obligations. Pursuant to the Master Agreement, the District is required, to the extent permitted by law, to fix, prescribe and collect fees and charges for the services and facilities of the Wastewater System which will be at least sufficient to yield during each Fiscal Year (a) Net Revenues equal to 125% of Debt Service on Senior Obligations for such Fiscal Year and (b) Net Operating Revenues equal to 100% of Debt Service on all Obligations for such Fiscal Year. The District may make adjustments from time to time in such fees and charges and may make such classification thereof as it deems necessary, but shall not reduce the fees and charges then in effect unless the Revenues and Net Revenues from such reduced fees and charges will at all times be sufficient to meet the requirements of the Master Agreement. See “SECURITY AND SOURCES OF PAYMENT FOR THE REVENUE OBLIGATIONS — Rate Covenant” in the Preliminary Official Statement. Additional Obligations In addition to the Existing Senior Obligations, the District may at any time incur Obligations payable on parity or on a subordinate basis to the payment by the District of the Installment Payments upon satisfaction of conditions provided in the Master Agreement. No Obligations payable on such a subordinate basis are currently outstanding. See “SECURITY AND SOURCES OF PAYMENT FOR THE REVENUE OBLIGATIONS — Limitations on Issuance of Additional Obligations” in the Preliminary Official Statement. 298913430.3 4 Book-Entry-Only The Revenue Obligations will be executed and delivered in the form of fully registered certificates payable in lawful money of the United States of America. The Revenue Obligations will be initially delivered only in book-entry form and will be registered in the name of Cede & Co., as nominee of The Depository Trust Company, New York, New York (“DTC”), which will act as securities depository for the Revenue Obligations. Individual purchases of the Revenue Obligations will be made in book-entry form only. Purchasers of Revenue Obligations will not receive physical certificates representing their ownership interests in the Revenue Obligations purchased. The Revenue Obligations will be delivered in Authorized Denominations of $5,000 and any integral multiple thereof. Payments of principal and interest evidenced by the Revenue Obligations are payable directly to DTC by the Trustee. Upon receipt of payments of such principal and interest, DTC will in turn distribute such payments to the beneficial owners of the Revenue Obligations. So long as the Revenue Obligations are in the DTC book-entry system, the interest, principal and prepayment premiums, if any, due with respect to the Revenue Obligations will be payable by the Trustee, or its agent, to DTC or its nominee. Principal and Interest Payments The Revenue Obligations will be dated as of the date of initial delivery and will evidence interest from that date (computed on the basis of a 360-day year of twelve 30-day months). Interest evidenced by the Revenue Obligations is payable semiannually on February 1 and August 1 of each year, commencing on [February 1, 2026]. Payment of principal and prepayment premium, if any, evidenced by the Revenue Obligations will be paid in lawful money of the United States of America upon presentation and surrender thereof at the Principal Office of the Trustee. Principal Amortization The Revenue Obligations will be executed and delivered in the original principal amount of $[PAR]* and will be subject to principal amortization on February 1 in the years 20__* through 20__* in the amounts set forth in the Official Bid Form. Prepayment Optional Prepayment. The Revenue Obligations with stated Principal Payment Dates on or after February 1, 20___* are subject to optional prepayment prior to their stated Principal Payment Dates, on any date on or after February 1, 20___*, in whole or in part, in Authorized Denominations, from and to the extent of prepaid Installment Payments paid pursuant to the Installment Purchase Agreement or from any other source of available funds, any such prepayment to be at a price equal to the principal evidenced by the Revenue Obligations to be prepaid, plus accrued interest evidenced thereby to the date fixed for prepayment, without premium. Mandatory Sinking Account Prepayment. If the successful bidder designates principal amounts to be combined into one or more term maturities, each such term maturity shall be subject to prepayment, in part, by lot, prior to maturity from mandatory sinking account payments commencing on February 1 of the first year which has been combined to form such term maturities and continuing on February 1 in each year thereafter until the stated maturity date of that term maturity. The prepayment price will be equal to * Preliminary, subject to change. 298913430.3 5 the principal amount for such year set forth in the Official Bid Form, plus accrued interest evidenced thereby to the date fixed for prepayment, without premium. Selection of Revenue Obligations for Prepayment Whenever less than all the Outstanding Revenue Obligations are to be prepaid on any one date pursuant to the provisions of the Trust Agreement, with respect to optional prepayment of Revenue Obligations, the Trustee shall select the Revenue Obligations to be prepaid among Revenue Obligations with different Principal Payment Dates as directed in a Written Request of the District. Whenever less than all the Outstanding Revenue Obligations with the same stated Principal Payment Date are to be prepaid on any one date pursuant to the Trust Agreement, the Trustee shall select the Revenue Obligations with such Principal Payment Date to be prepaid as directed in a Written Request of the District, or at the discretion of the District by lot in any manner that the Trustee deems fair and appropriate, which decision shall be final and binding upon the District and the Owners. The Trustee shall promptly notify the District in writing of the numbers of the Revenue Obligations so selected for prepayment on such date. Notice of Prepayment The Trustee shall, at least 20 but not more than 60 days prior to any prepayment date, give notice of prepayment to the respective Owners of Revenue Obligations designated for prepayment by first-class mail, postage prepaid, at their addresses appearing on the registration books maintained by the Trustee as of the close of business on the day before such notice of prepayment is given. The actual receipt by the Owner of any notice of such prepayment shall not be a condition precedent to prepayment, and neither failure to receive such notice nor any defect therein shall affect the validity of the proceedings for the prepayment of such Revenue Obligations or the cessation of interest evidenced thereby on the date fixed for prepayment. Interest Rates, Reoffering Prices, Premium or Discount Bids and Certificate of Initial Purchaser Bidders must bid to purchase all and not part of the Revenue Obligations and must submit their bids on the Official Bid Form. Bidders must specify a rate of interest for each maturity of the Revenue Obligations. The rates of interest must be expressed in multiples of either one-eighth (1/8) or one-twentieth (1/20) of one percent (1%), and no interest rate on the Revenue Obligations may be specified at zero percent (0%) [or greater than five percent (5.0%) and no Revenue Obligations maturing on and after February 1, 2035, inclusive, may be specified at less than five percent (5.0%) per annum]. All Revenue Obligations of the same maturity must evidence interest at the same rate. The successful bidder will, within 30 minutes after being notified of the award of the Revenue Obligations, advise the District of the initial bona fide public reoffering prices of each maturity of the Revenue Obligations on the date of award. The successful bidder will also be required to furnish to the District a certificate (“Certificate of Initial Purchaser”) in the applicable form of the Certificate of Initial Purchaser attached hereto (with such modifications as may be acceptable to Special Counsel). At any time before or after delivery of the Revenue Obligations to the successful bidder, that successful bidder also may be required by the District or Special Counsel to clarify any discrepancies between the Certificate of Initial Purchaser and publicly available information relating to trades of the Revenue Obligations that might suggest that the initial sale of a substantial portion of any maturity of the Revenue Obligations to the public was at a materially higher price than the price stated for that maturity in the Certificate of Initial Purchaser. Bidders may bid to purchase the Revenue Obligations from the District at a discount or with a premium; however, no bid will be considered if the bid is to purchase Revenue Obligations at an aggregate price less than 100% of the aggregate principal amount of the Revenue Obligations. 298913430.3 6 No bid will be accepted that contemplates the waiver of any interest or other concession by the bidder as substitute for payment in full of the purchase price. Bids that do not conform to the terms of this section may be rejected. See “Right to Reject Bids, Waive Irregularities” below. Adjustment of Principal Amounts After Receipt of Bids The principal amounts of the Revenue Obligations set forth in the Official Bid Form reflect estimates of the District as to the likely interest rates of the winning bid and the premium or discount contained in the winning bid. After selecting the winning bid, the amortization schedule for the Revenue Obligations will be adjusted in $5,000 increments, to reflect the actual interest rates and any discount or premium in the winning bid to properly fund the purchase price of the Refunded Prior Obligations and to accommodate certain other requirements or preferences of the District. The dollar amount bid for the Revenue Obligations by the winning bidder will be adjusted to reflect such adjustment in the applicable amortization schedule. Any such adjustment will change the total (but not the per Revenue Obligation) dollar amount of purchaser’s discount and original issue discount or premium, if any, provided in such bid. Any such adjustment will be communicated to the winning bidder within 24 hours after receipt of such bid by the District. Changes in the amortization schedule made as described in this paragraph will not affect the determination of the winning bidder or give the winning bidder any right to reject the Revenue Obligations. No Insurance THE SUCCESSFUL BIDDER SHALL NOT PURCHASE MUNICIPAL BOND INSURANCE IN CONNECTION WITH THE REVENUE OBLIGATIONS. Form of Bid BIDS FOR LESS THAN ALL OF THE REVENUE OBLIGATIONS WILL NOT BE ACCEPTED. Each bid must be on the Official Bid Form, submitted through the Electronic Service as specified herein. All electronic proposals shall be deemed to incorporate the provisions of the Official Bid Form and must be unconditional and irrevocable. In addition, each bidder is requested to supply an estimate of the true interest cost resulting from its bid, computed as prescribed below under the caption “Award, Delivery and Payment,” which shall be considered as informative only and not binding on either the bidder or the District. Each bid must be in accordance with the terms and conditions set forth in this Official Notice Inviting Bids. The District will make its best efforts to accommodate electronic bids; however, the District, the Municipal Advisor (PFM Financial Advisors LLC) and Special Counsel assume no responsibility for any error contained in any electronic bid, or for the failure of any electronic bid to be transmitted or received at the official time for receipt of such bids. The official time for receipt of bids will be determined by the District at the place of the bid opening, and the District shall not be required to accept the time kept by Electronic Service as the official time. The District assumes no responsibility for informing any bidder prior to the deadline that its bid is incomplete, or not received. If multiple timely bids are received from a single bidder the District shall accept the best of such bids and each bidder agrees, by submitting any bid, to be bound by its best bid. Information Regarding Electronic Proposals All proposals must be submitted through the Electronic Service. If any provision of this Official Notice Inviting Bids conflicts with information provided by the Electronic Service, this Official Notice 298913430.3 7 Inviting Bids shall control. The District is not responsible for the proper operation of, and shall have no liability for any delays or interruptions of or any damages caused by the Electronic Service.

The cost for the assignment of CUSIP numbers to the Revenue Obligations will be the responsibility of the successful bidder.

Reoffering Prices, Establishment of Issue Price and Issue Price Certificate (a) The winning bidder for the Revenue Obligations shall assist the District in establishing the issue price of the Revenue Obligations, and shall execute and deliver to the District at or before the time of issuance and delivery of the Revenue Obligations an “issue price” or similar certificate setting forth the reasonably expected initial offering price to the public of each maturity of the Revenue Obligations, together with the supporting pricing wires or equivalent communications, substantially in the form attached hereto as Exhibits A and B, as applicable, with such modifications as may be appropriate or necessary, in the reasonable judgment of the winning bidder, the District and Special Counsel. (b) The District intends that Sections 1.148-1(f)(2)(iii) and 1.148-1(f)(3)(i) (providing a special rule establishing the issue price of competitively sold bonds and defining the term “competitive sale”) will apply to the initial sale of the Revenue Obligations (the “Competitive Sale Requirements”) because: (1) the District shall disseminate this Official Notice Inviting Bids to potential underwriters in a manner that is reasonably designed to reach potential underwriters; (2) all bidders shall have an equal opportunity to bid on the Revenue Obligations; 298913430.3 9 (3) the District may receive bids for the Revenue Obligations from at least three underwriters of municipal bonds who have established industry reputations for underwriting new issuances of municipal bonds; and (4) the District anticipates awarding the sale of the Revenue Obligations to the bidder that submits a firm offer to purchase the Revenue Obligations at the highest price (or lowest interest cost), as set forth in this Official Notice Inviting Bids. Any bid submitted pursuant to this Official Notice Inviting Bids shall be considered a firm offer for the purchase of the Revenue Obligations as specified in the bid. (c) If the Competitive Sale Requirements set forth in subsection (b)(3) of this Section are not satisfied, the District shall so advise the winning bidder. In such event, the District intends to treat the initial offering price to the public as of the sale date of each maturity as the issue price of that maturity (the “hold-the-offering-price rule”). The District shall promptly advise the winning bidder, at or before the time of award, if the Competitive Sale Requirements set forth in subsection (b)(3) of this Section were not satisfied, in which case the hold-the-offering-price rule shall apply to the Revenue Obligations. Bids will not be subject to cancellation in the event the Competitive Sale Requirements are not satisfied, and the hold-the-offering-price rule thus apply to any maturity of the Revenue Obligations as to which less than 10% of the maturity was sold by the winning bidder to the public at a single price. (d) By submitting a bid to purchase the Revenue Obligations, the winning bidder (i) confirms that the underwriters that are part of the selling group (if any) (the “Underwriters”) have offered or will offer the Revenue Obligations to the public on or before the date of award at the offering price or prices (“initial offering price”), or at the corresponding yield or yields, set forth in the bid submitted by the winning bidder (ii) certifies that the bidder is an underwriter of municipal obligations who has an established industry reputation for underwriting new issuances of municipal obligations, and (iii) agrees, on behalf of the Underwriters, that the Underwriters will neither offer nor sell unsold Revenue Obligations of any maturity to which the hold-the-offering-price rule applies to any person at a price that is higher than the initial offering price to the public during the period starting on the sale date and ending on the earlier of the following: (1) the close of the fifth (5th) business day after the sale date; or (2) the date on which the Underwriters have sold at least 10% of that maturity of to the public at a price that is no higher than the initial offering price to the public. The winning bidder shall promptly advise the District when the underwriters have sold 10% of that maturity to the public at a price that is no higher than such maturity’s initial offering price to the public, if that occurs prior to the close of the fifth (5th) business day after the sale date. (e) The District acknowledges that, in making the representation set forth above, the winning bidder will rely on (i) the agreement of each underwriter to comply with the hold-the- offering-price rule, as set forth in an agreement among underwriters and the related pricing wires, (ii) in the event a selling group has been created in connection with the initial sale of the Revenue Obligations to the public, the agreement of each dealer who is a member of the selling group to comply with the hold-the-offering-price rule, as set forth in a selling 298913430.3 10 group agreement and the related pricing wires, and (iii) in the event that an underwriter is a party to a retail or other third-party distribution agreement that was employed in connection with the initial sale of the Revenue Obligations to the public, the agreement of each broker-dealer that is a party to such agreement to comply with the hold-the- offering- price rule, as set forth in the retail or other third-party distribution agreement and the related pricing wires. The District further acknowledges that each underwriter shall be solely liable for its failure to comply with its agreement regarding the hold-the-offering-price rule, and that no underwriter shall be liable for the failure of any other underwriter, or of any dealer who is a member of a selling group, or of any broker-dealer that is a party to a retail or other third-party distribution agreement to comply with its corresponding agreement regarding the hold-the-offering-price rule as applicable to one or more maturities of the Revenue Obligations. (f) By submitting a bid to purchase the Revenue Obligations, the bidder confirms that: (i) any agreement among underwriters, any selling group agreement and each retail or other third- party distribution agreement (to which the bidder is a party) relating to the initial sale of the Revenue Obligations to the public, together with the related pricing wires, contains or will contain language obligating each underwriter, each dealer who is a member of the selling group, and each broker-dealer that is a party to such retail or other third-party distribution agreement, as applicable, to (A) report the prices at which it sells to the public the unsold Revenue Obligations of each maturity allotted to it and subject to the hold-the- offering-price rule until it is notified by the winning bidder that the hold-the-offering-price rule no longer applies to such maturity, and (B) comply with the hold-the-offering-price rule, if applicable, in each case if and for so long as directed by the winning bidder and as set forth in the related pricing wires, and (ii) any agreement among underwriters relating to the initial sale of the Revenue Obligations to the public, together with the related pricing wires, contains or will contain language obligating each underwriter that is a party to a retail or other third-party distribution agreement to be employed in connection with the initial sale of the Revenue Obligations to the public to require each broker-dealer that is a party to such retail or other third-party distribution agreement to (A) report the prices at which it sells to the public the unsold Revenue Obligations of each maturity allotted to it and subject to the hold-the-offering-price rule until it is notified by the winning bidder or such underwriter that the hold-the-offering-price rule no longer applies to such maturity, and (B) comply with the hold-the-offering-price rule, if applicable, in each case if and for so long as directed by the winning bidder or such underwriter and as set forth in the related pricing wires. (g) Sales of the Revenue Obligations to any person that is a related party to an underwriter of the Revenue Obligations shall not constitute sales to the public for purposes of this Official Notice inviting Bids. Further, for purposes of this Official Notice Inviting Bids: (1) “public” means any person other than an underwriter or a related party, (2) “underwriter” means (A) any person that agrees pursuant to a written contract with the District (or with the lead underwriter to form an underwriting syndicate) to participate in the initial sale of the Revenue Obligations to the public, and (B) any person that agrees pursuant to a written contract directly or indirectly with a person described in clause (A) to participate in the initial sale of the Revenue Obligations to the public (including a member of a selling group or a party to a retail or other third-party distribution agreement participating in the initial sale of the Revenue Obligations to the public), 298913430.3 11 (3) a purchaser of the Revenue Obligations is a “related party” to an underwriter if the underwriter and the purchaser are subject, directly or indirectly, to (i) more than 50% common ownership of the voting power or the total value of their stock, if both entities are corporations (including direct ownership by one corporation of another), (ii) more than 50% common ownership of their capital interests or profits interests, if both entities are partnerships (including direct ownership by one partnership of another), or (iii) more than 50% common ownership of the value of the outstanding stock of the corporation or the capital interests or profit interests of the partnership, as applicable, if one entity is a corporation and the other entity is a partnership (including direct ownership of the applicable stock or interests by one entity of the other), and (4) “sale date” means the date on which the Revenue Obligations are awarded by the District to the winning bidder.

All statements contained in this introduction are qualified in their entirety by reference to the entire Official Statement. References to, and summaries of, provisions of the Constitution and laws of the State of California (the “State”) and any documents referred to herein do not purport to be complete and such references are qualified in their entirety by reference to the complete provisions. All capitalized terms used in this Official Statement and not otherwise defined herein have the meanings set forth in the Trust Agreement, the Installment Purchase Agreement and the Master Agreement (each, as hereinafter defined). See APPENDIX C – “SUMMARY OF PRINCIPAL LEGAL DOCUMENTS – Definitions” herein. General This Official Statement, including the cover page and all appendices hereto, provides certain information concerning the sale and delivery of $___________* aggregate principal amount of the Orange County Sanitation District Wastewater Refunding Revenue Obligations, Series 2025A (the “Revenue Obligations”), which are certificates of participation evidencing direct, fractional undivided interests in certain installment payments (the “Installment Payments”) and the interest thereon, to be made by the Orange County Sanitation District (the “District”) pursuant to the Installment Purchase Agreement, dated as of November 1, 2025 (the “Installment Purchase Agreement”), by and between the District and the Orange County Sanitation District Financing Corporation (the “Corporation”). Unless the context clearly indicates to the contrary, a reference herein to either of the Installment Purchase Agreement or the Revenue Obligations is intended to refer to the corresponding interest in the Installment Purchase Agreement. Pursuant to the Master Agreement for District Obligations, dated as of August 1, 2000 (the “Master Agreement”), by and between the District and the Corporation, the District has established and declared the conditions and terms upon which obligations such as the Installment Purchase Agreement, and the Installment Payments and the interest thereon, will be incurred and secured. Installment Payments under the Installment Purchase Agreement are payable solely from Net Revenues (as defined hereinafter) as provided in the Installment Purchase Agreement, consisting primarily of all income and revenue received by the District from the operation or ownership of the Wastewater System of the District (the “Wastewater System”) remaining after payment of Maintenance and Operation Costs, as further described in “SECURITY AND SOURCES OF PAYMENT FOR THE REVENUE OBLIGATIONS” herein. The Revenue Obligations are to be executed and delivered pursuant to a Trust Agreement, dated as of November 1, 2025 (the “Trust Agreement”), by and among the District, the Corporation and U.S. Bank Trust Company, National Association, as successor trustee (the “Trustee”). Proceeds from the sale of the Revenue Obligations will be used, together with other available funds, to (i) prepay [all/a portion] of the District’s Wastewater Refunding Revenue Obligations, Series 2016A in the aggregate principal amount of $[___] (the “Refunded 2016A Obligations”) and (ii) pay the costs incurred in connection with the execution and delivery of the Revenue Obligations. See “REFUNDING PLAN” herein. * Preliminary, subject to change. 298610182.5 2 The Revenue Obligations will be executed and delivered in the form of fully registered certificates of participation, dated as of the date of initial delivery thereof and will mature on February 1 in each such year as set forth on the inside cover page hereof. Interest evidenced by the Revenue Obligations will be payable semiannually on February 1 and August 1 of each year, commencing on February 1, 2026. See “THE REVENUE OBLIGATIONS” herein. The Revenue Obligations initially will be delivered only in book-entry form and will be registered in the name of Cede & Co., as nominee of The Depository Trust Company, New York, New York (“DTC”), which will act as securities depository for the Revenue Obligations. The Revenue Obligations will be delivered in denominations of $5,000 and any integral multiple thereof. So long as the Revenue Obligations are in the DTC book-entry system, the interest, principal, purchase price and prepayment premiums, if any, due with respect to the Revenue Obligations will be payable by the Trustee, or its agent, to DTC or its nominee. DTC, in turn, will make payments pursuant to its procedures as described under APPENDIX E – “BOOK–ENTRY SYSTEM” herein. The District The District is a public agency responsible for regional wastewater collection, treatment, recycling and disposal services. The District is the third largest regional wastewater agency west of the Mississippi River. The District provides service to an area with a population of approximately 2.6 million people in the central and northwest portion of the County of Orange (the “County”), in a service area of approximately 479 square miles, treating an average of 184 million gallons per day (“mgd”) of wastewater in Fiscal Year 2024-25. See “THE DISTRICT,” “DISTRICT REVENUES” and “FINANCIAL OBLIGATIONS” herein. Security and Sources of Payment for the Revenue Obligations The Revenue Obligations, which are certificates of participation, evidence direct, fractional undivided interests in the Installment Payments, and the interest thereon, paid by the District pursuant to the Installment Purchase Agreement. The obligation of the District to pay the Installment Payments and the interest thereon and other payments required to be made by it under the Installment Purchase Agreement is a special obligation of the District payable, in the manner provided under the Installment Purchase Agreement, solely from Net Revenues, and other funds as provided in the Installment Purchase Agreement. Net Revenues generally consist of all income and revenue received by the District from the operation or ownership of the Wastewater System remaining after payment of Maintenance and Operation Costs, all as further provided in the Master Agreement. The Installment Purchase Agreement constitutes a Senior Obligation and, as such, is subject to the provisions of the Master Agreement and is afforded all of the advantages, benefits, interests and security afforded Senior Obligations pursuant to the Master Agreement. The District currently has Outstanding Senior Obligations payable from Net Revenues on parity with the Installment Payments under the Installment Purchase Agreement. See “ESTIMATED SOURCES AND USES OF FUNDS,” “FINANCIAL OBLIGATIONS – Existing Indebtedness” and “THE DISTRICT” herein and APPENDIX C – “SUMMARY OF PRINCIPAL LEGAL DOCUMENTS – Master Agreement” attached hereto. The District has no Subordinate Obligations currently outstanding. Pursuant to the Master Agreement, the District will, to the extent permitted by law, fix, prescribe and collect fees and charges for the services and facilities of the Wastewater System which will be at least sufficient to yield during each Fiscal Year (a) Net Revenues equal to 125% of Debt Service on Senior Obligations for such Fiscal Year and (b) Net Operating Revenues equal to 100% of Debt Service on all Obligations for such Fiscal Year. The District may make adjustments from time to time in such fees and charges and may make such classification thereof as it deems necessary, but shall not reduce the fees and charges then in effect unless the Revenues and Net Revenues from such reduced fees and charges will at all times be sufficient to meet the requirements of the Master Agreement. See “SECURITY AND SOURCE OF PAYMENT FOR THE REVENUE OBLIGATIONS – Rate Covenant” herein. 298610182.5 3 The obligation of the District to pay the Installment Payments and the interest thereon, and other payments required to be made by it under the Installment Purchase Agreement is a special obligation of the District payable, in the manner provided in the Installment Purchase Agreement, solely from Net Revenues and other funds provided for in the Installment Purchase Agreement, and does not constitute a debt of the District or of the State, or of any political subdivision thereof, in contravention of any constitutional or statutory debt limitation or restriction. Neither the faith and credit nor the taxing power of the District or the State or any political subdivision thereof, is pledged to the payment of the Installment Payments, or the interest thereon, or other payments required to be made under the Installment Purchase Agreement. The Installment Purchase Agreement constitutes a Senior Obligation and, as such, is subject to the provisions of the Master Agreement and is afforded all of the advantages, benefits, interests and security afforded Senior Obligations pursuant to the Master Agreement. See “SECURITY AND SOURCES OF PAYMENT FOR THE REVENUE OBLIGATIONS” herein. Continuing Disclosure The District has covenanted for the benefit of holders and beneficial owners of the Revenue Obligations (a) to provide certain financial information and operating data (the “Annual Report”) relating to the District and the property in the District not later than eight months after the end of the District’s Fiscal Year (which currently would be March 1), commencing with the report for the 2024-25 Fiscal Year, and (b) to provide notices of the occurrence of certain enumerated events. The specific nature of the information to be contained in the Annual Report or the notices of enumerated events is set forth in the Continuing Disclosure Agreement.

Whenever less than all the Outstanding Revenue Obligations with the same stated Principal Payment Date are to be prepaid on any one date pursuant to the provisions of the Trust Agreement, the Trustee shall select the Revenue Obligations with such Principal Payment Date to be 298610182.5 7 prepaid as directed in a Written Request of the District, or at the discretion of the District by lot in any manner that the Trustee deems fair and appropriate, which decision shall be final and binding upon the District and the Owners. The Trustee shall promptly notify the District in writing of the numbers of the Revenue Obligations so selected for prepayment on such date. For purposes of such selection, any Revenue Obligation may be prepaid in part in Authorized Denominations. Notice of Prepayment. When prepayment of Revenue Obligations is authorized pursuant to the Trust Agreement, the Trustee shall give notice, at the expense of the District, of the prepayment of the Revenue Obligations. The notice of prepayment shall specify (a) the Revenue Obligations or designated portions thereof (in the case of prepayment of the Revenue Obligations in part but not in whole) which are to be prepaid, (b) the date of prepayment, (c) the place or places where the prepayment will be made, including the name and address of any paying agent, (d) the prepayment price, (e) the CUSIP numbers assigned to the Revenue Obligations to be prepaid, (f) the numbers of the Revenue Obligations to be prepaid in whole or in part and, in the case of any Revenue Obligation to be prepaid in part only, the principal evidenced by such Revenue Obligation to be prepaid, and (g) the interest rate and stated Principal Payment Date of each Revenue Obligation to be prepaid in whole or in part. Such notice of prepayment shall further state that on the specified date there shall become due and payable upon each Revenue Obligation or portion thereof being prepaid the prepayment price and that from and after such date interest evidenced thereby shall cease to accrue and be payable. The Trustee shall, at least 20 but not more than 60 days prior to any prepayment date, give notice of prepayment to the respective Owners of Revenue Obligations designated for prepayment by [first-class mail, postage prepaid], at their addresses appearing on the registration books maintained by the Trustee as of the close of business on the day before such notice of prepayment is given. The actual receipt by the Owner of any notice of such prepayment shall not be a condition precedent to prepayment, and neither failure to receive such notice nor any defect therein shall affect the validity of the proceedings for the prepayment of such Revenue Obligations or the cessation of interest evidenced thereby on the date fixed for prepayment. Effect of Prepayment. If notice of prepayment has been duly given as aforesaid and moneys for the payment of the prepayment price of the Revenue Obligations to be prepaid are held by the Trustee, then on the prepayment date designated in such notice, the Revenue Obligations so called for prepayment shall become payable at the prepayment price specified in such notice; and from and after the date so designated, interest evidenced by the Revenue Obligations so called for prepayment shall cease to accrue, such Revenue Obligations shall cease to be entitled to any benefit or security hereunder and the Owners of such Revenue Obligations shall have no rights in respect thereof except to receive payment of the prepayment price thereof. The Trustee shall, upon surrender for payment of any of the Revenue Obligations to be prepaid, pay such Revenue Obligations at the prepayment price thereof, and such moneys shall be pledged to such payment. SECURITY AND SOURCES OF PAYMENT FOR THE REVENUE OBLIGATIONS Installment Payments Pursuant to the Installment Purchase Agreement, the Project will be reacquired by the District from the Corporation. The District has covenanted to pay to the Corporation, solely from Net Revenues and from no other sources, the Purchase Price in Installment Payments, with interest thereon, as provided in the Installment Purchase Agreement. Pursuant to the Master Agreement, the District has established and declared the conditions and terms upon which obligations such as the Installment Purchase Agreement, and the Installment Payments and the interest thereon payable under the Installment Purchase Agreement, will 298610182.5 8 be incurred and secured. The obligation of the District to make the Installment Payments, and payments of interest thereon, and other payments required to be made by it under the Installment Purchase Agreement, solely from Net Revenues, is absolute and unconditional, and until such time as the Installment Payments, payments of interest thereon, and such other payments shall have been paid in full (or provision for the payment thereof shall have been made pursuant to the Installment Purchase Agreement), the District has covenanted that it will not discontinue or suspend any Installment Payments when due, whether or not the Project or any part thereof is operating or operable or has been completed, or its use is suspended, interfered with, reduced or curtailed or terminated in whole or in part, and such Installment Payments, payments of interest thereon, and other payments shall not be subject to reduction whether offset or otherwise and shall not be conditional upon the performance or nonperformance by any party of any agreement or any cause whatsoever. The District’s obligation to make Installment Payments from Net Revenues is on parity with the District’s obligation to make payments with respect to its Outstanding Senior Obligations. See “Net Revenues” below. Pursuant to the Trust Agreement, the Corporation has assigned to the Trustee for the benefit of the Owners of the Revenue Obligations substantially all of its rights, title and interest in and to the Installment Purchase Agreement, including its right to receive Installment Payments and the interest thereon. The District has certain Existing Senior Obligations Outstanding payable from Net Revenues on parity with the Installment Payments under the Installment Purchase Agreement. The term “Existing Senior Obligations” as used in this Official Statement refers to the Installment Purchase Agreements relating to the District’s currently Outstanding Senior Obligations, as set forth on Table 16 under the caption “FINANCIAL OBLIGATIONS – Existing Indebtedness” herein. The term “Senior Obligations” as used in this Official Statement refers to the Existing Senior Obligations and to any additional Senior Obligations, such as the Installment Purchase Agreement, that may be made payable on a parity basis to the Installment Payments as provided in the Master Agreement. Senior Obligations, together with any Subordinate Obligations payable on a subordinate basis to the Installment Payments incurred as provided in the Master Agreement, are referred to collectively as the “Obligations.” The District has no Subordinate Obligations currently outstanding. See “FINANCIAL OBLIGATIONS — Existing Indebtedness” herein and APPENDIX C — “SUMMARY OF PRINCIPAL LEGAL DOCUMENTS — Master Agreement” attached hereto. The obligation of the District to pay the Installment Payments, and the interest thereon, and other payments required to be made by it under the Installment Purchase Agreement and Master Agreement, is a special obligation of the District payable, in the manner provided in the Installment Purchase Agreement, solely from Net Revenues and other funds provided for in the Installment Purchase Agreement, and does not constitute a debt of the District, the State or any political subdivision thereof, in contravention of any constitutional or statutory debt limitation or restriction. Neither the faith and credit nor the taxing power of the District, the State or any political subdivision thereof, is pledged to the payment of the Installment Payments, or the interest thereon, or other payments required to be made under the Installment Purchase Agreement. The Installment Purchase Agreement constitutes a Senior Obligation and, as such, is subject to the provisions of the Master Agreement and is afforded all of the advantages, benefits, interests and security afforded Senior Obligations pursuant to the Master Agreement. See “SECURITY AND SOURCES OF PAYMENT FOR THE REVENUE OBLIGATIONS” herein. Available Funds of the District As Senior Obligations under the Master Agreement, the Installment Payments are payable from and secured by a pledge of Net Revenues. Should Net Revenues prove insufficient, the Installment Purchase Agreement further provides that the Installment Payments are payable from any other lawfully available funds of the District. 298610182.5 9 The primary lawfully available funds of the District are its reserve funds, other than trustee-held amounts required to be in any Obligation Reserve Fund securing certain of the District’s Senior Obligations, as described in the Master Agreement. The District has an established reserve policy with seven distinct reserve criteria which together comprise the District’s reserve fund target. Over a ten-fiscal year period, these requirements collectively result in a year-ending reserve total for each fiscal year projected not to fall below $564 million as indicated in the District’s ten-year cash flow forecast for fiscal years 2025-26 through 2034-35. Collectively, these requirements average $570 million a year over the current ten-year cash flow forecast to support the operation and maintenance of the District’s $15.7 billion in assets. The District’s reserves are not held in segregated accounts. The Debt Service Required Reserves criterion has been established at ten percent of outstanding certificates of participation. Other debt service reserves are required to be under the control of a Trustee by the provisions of such securities. These funds are not available for the general needs of the District and must be maintained at specified levels. At June 30, 2025, the District’s Debt Service Required Reserves totaled $57 million, of which $0 were trustee-held amounts in Obligation Reserve Funds under the Master Agreement. See APPENDIX C – “SUMMARY OF PRINCIPAL LEGAL DOCUMENTS – Master Agreement” attached hereto. District reserve funds are maintained in accordance with the District’s reserve policy. See “DISTRICT REVENUES – Reserves.” Available reserves at June 30, 2025 were approximately $919 million. See “DISTRICT REVENUES — Reserves,” “— Summary of Operating Data” and “— Projected Operating Data.” Net Revenues The District is obligated to make Installment Payments from, among other things, Net Revenues as provided in the Master Agreement, which consist of Revenues remaining after payment of costs paid by the District for maintaining and operating the Wastewater System (“Maintenance and Operation Costs”). Revenues are defined in the Master Agreement to mean, for any period, all income and revenue received by the District during such period from the operation or ownership of the Wastewater System, determined in accordance with generally accepted accounting principles, including all fees and charges received during such period for the services of the Wastewater System, investment income received during such period (but only to the extent that such investment income is generally available to pay costs with respect to the Wastewater System, including Maintenance and Operation Costs), Net Proceeds of business interruption insurance received during such period, ad valorem taxes received during such period, payments under the Agreement Acquiring Ownership Interests, Assigning Rights and Establishing Obligations, entered into on February 13, 1986, and amendment No. 1 thereto dated December 10, 1986 (the “IRWD Agreement”), by and between predecessor County Sanitation District No. 14 of Orange County and the Irvine Ranch Water District (the “IRWD”) received during such period and all other money received during such period howsoever derived by the District from the operation or ownership of the Wastewater System or arising from the Wastewater System (including any standby or availability charges), but excluding (a) Capital Facilities Capacity Charges, (b) payments received under Financial Contracts, and (c) refundable deposits made to establish credit and advances or contributions in aid of construction (which, for purposes of the Master Agreement, shall not include payments under the IRWD Agreement); provided, however, that (i) Revenues shall be increased by the amounts, if any, transferred during such period from the Rate Stabilization Account to the Revenue Account and shall be decreased by the amounts, if any, transferred during such period from the Revenue Account to the Rate Stabilization Account, and (ii) Revenues shall include Capital Facilities Capacity Charges collected during such period to the extent that such Capital Facilities Capacity Charges could be properly expended on a Capital Facilities Capacity Charge Eligible Project for which the proceeds of Senior Obligations were used or are available to be used. Any Federal 298610182.5 10 Subsidy payments received by the District will constitute Revenues as defined in the Master Agreement. See “DISTRICT REVENUES — Additional Revenues” herein. The District’s obligation to make the Installment Payments from its Net Revenues is on parity with the District’s obligation to make payments with respect to its other outstanding obligations described as Senior Obligations and all Reimbursement Obligations with respect to Senior Obligations, as provided in the Master Agreement. The Installment Purchase Agreement constitutes a Senior Obligation and, as such, is subject to the provisions of the Master Agreement and is afforded all of the advantages, benefits, interests and security afforded Senior Obligations pursuant to the Master Agreement. Pursuant to the Master Agreement, the District pledges all Net Revenues to the payment of the Senior Obligations and Reimbursement Obligations with respect to Senior Obligations, and the Net Revenues will not be used for any other purpose while any of the Senior Obligations or Reimbursement Obligations with respect to Senior Obligations remain unpaid; provided, however, that out of the Net Revenues there may be apportioned such sums for such purposes as are expressly permitted by the Master Agreement. This pledge constitutes a first lien on the Net Revenues for the payment of the Senior Obligations and Reimbursement Obligations with respect to Senior Obligations. The term “Senior Obligations” generally means all revenue bonds or notes (including bond anticipation notes and commercial paper) of the District authorized, issued, executed and delivered under and pursuant to applicable law, the Installment Purchase Agreement, and all other contracts (including financial contracts) or leases of the District authorized and executed by the District under and pursuant to applicable law, including, without limitation, installment, lease or other payments which are, in accordance with the provisions of the Master Agreement, payable from Net Revenues on parity with the payments under the Master Agreement. The District may at any time incur Subordinate Obligations payable on a subordinate basis to the Installment Payments as provided in the Master Agreement; provided, however, that prior to incurring such Subordinate Obligations, the District shall have determined that the incurrence thereof will not materially adversely affect the District’s ability to comply with the requirements of the Master Agreement. The District may at any time incur Reimbursement Obligations with respect to Subordinate Obligations. For a description of the District’s Outstanding Senior Obligations and Subordinate Obligations, see “FINANCIAL OBLIGATIONS — Existing Indebtedness” herein. There are currently no Subordinate Obligations or Reimbursement Obligations with respect to Subordinate Obligations outstanding. The District may, in connection with the incurrence of Subordinate Obligations, pledge Net Revenues to the payment of Subordinate Obligations and Reimbursement Obligations with respect to Subordinate Obligations; provided, however, that such pledge, and any lien created thereby, shall be junior and subordinate to the pledge of, and lien on, Net Revenues for the payment of Senior Obligations and Reimbursement Obligations with respect to Senior Obligations. Rate Stabilization Account To avoid fluctuations in its fees and charges of the Wastewater System, from time to time the District may deposit in the Rate Stabilization Account from Net Revenues such amounts as the District deems necessary or appropriate. From time to time, the District may also transfer moneys from the Rate Stabilization Account to the Revenue Account to be used by the District, first to pay all Maintenance and Operations Costs as and when the same shall be due and payable. In addition, any such amount transferred from the Rate Stabilization Account to the Revenue Account by the District is included as Revenues for any period, but such transferred amount is excluded from determining Operating Revenues for any period. Revenues will be decreased by the amounts, if any, transferred from the Revenue Account to the Rate Stabilization Account. There are presently no funds in the Rate Stabilization Account. 298610182.5 11 Allocation of Revenues To carry out and effectuate the pledge of Net Revenues under the Master Agreement as described above, the District agrees and covenants that all Operating Revenues received by the District will be deposited when and as received in the Revenue Account. Additionally, amounts may, from time to time as the District deems necessary or appropriate, be transferred from the Rate Stabilization Account and deposited in the Revenue Account, as described above under “— Rate Stabilization Account” above. The District will pay from the Revenue Account all Maintenance and Operations Costs (including amounts reasonably required to be set aside in contingency reserves for Maintenance and Operations Costs, the payment of which is not immediately required) as and when the same shall be due and payable. After having paid, or having made provisions for the payment of, Maintenance and Operations Costs, the District shall set aside and deposit or transfer, as the case may be, from the Revenue Account such amounts at such times as provided in the Master Agreement in the following order of priority: (1) Senior Obligation Payment Account; (2) Senior Obligation Reserve Funds (the Revenue Obligations are not secured by any Reserve Fund); (3) Subordinate Obligation Payment Account; (4) Subordinate Obligation Reserve Funds; and (5) Rate Stabilization Account. Amounts required or permitted to be deposited or transferred as described in items 2, 3, 4 and 5 above, shall not be so deposited or transferred unless the District shall have determined that there will be sufficient Net Revenues available to make the required deposits or transfers on the dates on which such deposits or transfers are required to be made as described above. So long as the District has determined that Net Revenues will be sufficient to make all of the deposits or transfers required to be made pursuant to items 1, 2, 3, 4 and 5 above, on the dates on which such deposits or transfers are required to be made, Net Revenues on deposit in the Revenue Account may from time to time be used for any purpose for which the District funds may be legally applied. For additional information, see APPENDIX C — “SUMMARY OF PRINCIPAL LEGAL DOCUMENTS — Master Agreement.” Rate Covenant Pursuant to the Master Agreement, the District will, to the extent permitted by law, fix, prescribe and collect fees and charges for the services of the Wastewater System which will be at least sufficient to yield during each Fiscal Year (a) Net Revenues equal to 125% of Debt Service on Senior Obligations for such Fiscal Year and (b) Net Operating Revenues equal to 100% of Debt Service on all Obligations for such Fiscal Year. The District may make adjustments from time to time in such fees and charges and may make such classification thereof as it deems necessary, but will not reduce the fees and charges then in effect unless the Revenues and Net Revenues from such reduced fees and charges will at all times be sufficient to meet the requirements of the Master Agreement. In addition, the District has covenanted in the Master Agreement to prepare and adopt an annual budget for the Wastewater System for each Fiscal Year. Such budget will set forth in reasonable detail the Revenues anticipated to be derived in such Fiscal Year and the expenditures anticipated to be paid or provided for therefrom in such Fiscal Year, including, without limitation, the amounts required to pay or 298610182.5 12 provide for the payment of the Obligations during such Fiscal Year, the amounts required to pay or provide for the payment of Maintenance and Operations Costs during such Fiscal Year and the amounts required to pay or provide for the payment of all other claims or obligations required to be paid from Revenues in such Fiscal Year, and will show that Revenues and Net Revenues will be at least sufficient to satisfy the requirements of the Master Agreement. On or before September 1 of each Fiscal Year, the District will file with the Trustee a copy of the adopted budget for such Fiscal Year. See APPENDIX C — “SUMMARY OF PRINCIPAL LEGAL DOCUMENTS — Master Agreement” for additional information. The District projects its reserves in each of the next ten fiscal years not to fall below $564 million. At its election, the District may use unrestricted reserves to help satisfy the rate covenant described above. See “DISTRICT REVENUES – Reserves” herein. Limitations on Issuance of Additional Obligations Senior Obligations. The District may at any time incur Senior Obligations in addition to the Existing Senior Obligations payable from Net Revenues as provided in the Master Agreement on parity with all other Senior Obligations theretofore incurred but only subject to the following conditions under the Master Agreement: (1) Upon the incurrence of such Senior Obligations, no Event of Default will be continuing under the Master Agreement; and (2) Subject to the provisions of the Master Agreement, the District will have received either one of the following: (i) A Written Certificate of the District certifying that, for a 12 consecutive calendar month period during the 24 consecutive calendar month period ending in the calendar month prior to the incurrence of such Senior Obligations (which 12 consecutive calendar month period will be specified in such certificate or certificates): (A) Net Revenues, as shown by the books of the District, will have amounted to at least 125% of Maximum Annual Debt Service on all Senior Obligations to be outstanding immediately after the incurrence of such Senior Obligations, and (B) Net Operating Revenues, as shown by the books of the District, will have amounted to at least 100% of Maximum Annual Debt Service on all Obligations to be outstanding immediately after the incurrence of such Senior Obligations. For purposes of demonstrating compliance with the foregoing, Net Revenues and Net Operating Revenues may be adjusted for (x) any changes in fees and charges for the services of the Wastewater System which have been adopted and are in effect on the date such Senior Obligations are incurred, but which, during all or any part of such 12 consecutive calendar month period, were not in effect, (y) customers added to the Wastewater System subsequent to such 12 consecutive calendar month period but prior to the date such Senior Obligations are incurred, and (z) the estimated change in available Net Revenues and Net Operating Revenues which will result from the connection of existing residences or businesses to the Wastewater System within one year following completion of any 298610182.5 13 project to be funded or any system to be acquired from the proceeds of such Senior Obligations; or (ii) A certificate or certificates from one or more Consultants which, when taken together, project that, for each of the two Fiscal Years next succeeding the incurrence of such Senior Obligations: (A) Net Revenues will amount to at least 125% of Maximum Annual Debt Service on all Senior Obligations to be outstanding immediately after the incurrence of such Senior Obligations, and (B) Net Operating Revenues will amount to at least 100% of Maximum Annual Debt Service on all Obligations to be outstanding immediately after the incurrence of such Senior Obligations. For purposes of demonstrating compliance with the foregoing, Net Revenues and Net Operating Revenues may be adjusted for (x) any changes in fees and charges for the services of the Wastewater System which have been adopted and are in effect on the date such Senior Obligations are incurred or will go into effect prior to the end of such two Fiscal Year period, (y) customers expected to be added to the Wastewater System prior to the end of such two Fiscal Year period, and (z) the estimated change in available Net Revenues and Net Operating Revenues which will result from the connection of existing residences or businesses to the Wastewater System within one year following completion of any project to be funded or any system to be acquired from the proceeds of such Senior Obligations.

See “REFUNDING PLAN” herein. THE DISTRICT Background The District is managed by the Board of Directors, whose members are appointed by 25 member cities and agencies which are serviced by the District. The District is a public agency responsible for construction and maintenance of a major portion of the wastewater collection, treatment, recycling and disposal facilities within its boundaries and is the third largest regional wastewater collection, treatment and recycling agency west of the Mississippi River. The District provides service to an area with a population of approximately 2.6 million people in the central and northwest portion of the County by treating an average of 184 mgd of wastewater in Fiscal Year 2024-25. The District serves approximately 81% of the County population in approximately 479 square miles, or approximately 60% of the County’s area. Local sanitary districts, water districts and cities are responsible for local sewers in the District’s service area. The District recycles 100% of their reclaimable flow. The service area which comprises the District was originally formed in 1954 pursuant to the County Sanitation District Act, as amended, Section 4700 et seq. of the Health and Safety Code of the State. The 298610182.5 16 District’s service area originally consisted of seven independent special districts in the County which were each responsible for matters relating to their individual districts. These special districts were jointly responsible for the treatment and disposal facilities which they each used. The seven independent districts were successors to the Joint Outfall Sewer Organization, which was formed in 1923 among the Cities of Anaheim, Santa Ana, Fullerton, and Orange, and the sanitary districts of Placentia, Buena Park, La Habra, and Garden Grove. The Joint Outfall Sewer Organization constructed a treatment plant and outfall in the early 1920s to serve its members. It was reorganized in 1947 and 1948 into seven county sanitation districts – District Nos. 1, 2, 3, 5, 6, 7 and 11. These prior districts were formed based on engineers’ analyses of the gravity flows in the service area. District No. 13 was formed in 1985 and District No. 14 was added in 1986. These districts were co-participants in a Joint Agreement which provided for the joint construction, ownership, and operation of the prior districts’ joint facilities. In April 1998, at the request of the Board of Directors of the District (the “Board of Directors”), the Board of Supervisors of the County of Orange (the “County Board”) passed Resolution No. 98-140 approving the consolidation of the then existing nine special districts into a new, single sanitation district, to be known as the Orange County Sanitation District. This action was designed to simplify governance structures, reduce the size of the Board of Directors, ease administrative processes, streamline decision- making and consolidate accounting and auditing processes. The consolidation was effective on July 1, 1998. Pursuant to Resolution No. 98-140 and Government Code Section 57500, the prior districts transferred and assigned all of their powers, rights, duties, obligations, functions and properties to the District, and the District assumed all obligations of the prior districts which were several and not joint including, without limitation, their obligations to repay the then outstanding certificates of participation. The boundaries of the nine predecessor special districts were initially used by the District to delineate separate revenue areas (the “Revenue Areas”) for budgeting and accounting purposes and in order to facilitate the imposition of fees and charges imposed by the District. See “DISTRICT REVENUES – Sewer Service Charges” herein. Organization and Administration The District is independent of and overlaps other political jurisdictions. There are many governmental entities, including the County, that operate within the District’s jurisdiction. These entities are exclusively responsible for the administration of their own fiscal affairs, and the District is not entitled to operating surpluses of, or responsible for operating deficits of, any of the other entities. The 25-member Board of Directors is composed of representatives from 20 cities, four special districts and a member representing the County. Several board committees, made up of members of the Board of Directors, consider topics for action by the Board of Directors and make recommendations to the Board of Directors. The Chairperson and the Vice Chairperson of the Board of Directors are elected every year by a majority of the Board of Directors and serve at the pleasure of a majority of the Board of Directors.

Generally, local agency systems collect wastewater from residential and industrial customers and convey the wastewater to District trunk sewer pipelines for conveyance to the District’s wastewater reclamation plants. The District’s staff is responsible for operating and maintaining the District’s infrastructure, although some work is performed by external contractors. Currently, the District has established supply contracts for all chemicals necessary to the operation and maintenance of the facilities with sufficient standby systems in the event of equipment failures or system outages. Service Area The map on the inside cover of this Official Statement shows the District’s boundaries and selected cities located within the District. District boundaries were originally established in 1947 and 1948 based on drainage basins. As the existing cities have grown and new areas have incorporated, city limits have come to overlap District boundaries. The District currently serves an approximately 479 square-mile area including 23 of the County’s 34 cities and various unincorporated areas of the County. The District serves a population of approximately 2.6 million residents.

(2) Center for Demographic Research, California State University, Fullerton. Employees As of June 30, 2025, the District had a total of approximately 629 employees. The majority of the District employees are represented by recognized employee organizations, which include the following: the Orange County Employees Association (“OCEA”), representing administrative/clerical, technical services and engineering employees since 1979, the International Union of Operating Engineers – Local 501 (“Local 501”), representing operations and maintenance employees since October 1985, and the Supervisory and Professional Management Group (“SPMT/AFSCME”), representing employees within the Supervisor Group and Professional Group since 1991. The total number of represented employees as of June 30, 2025 was 585, and is broken down as follows: 92 employees represented by OCEA, 192 employees represented by Local 501, and 301 employees represented by SPMT/AFSCME. In July 2025, the District reached final 298610182.5 20 agreement with all bargaining units on the current set of labor contracts that will expire on June 30, 2028. Historically, the District has experienced positive and collaborative working relationships with each organization and has not endured any work stoppages since its formation in 1998. Retirement Plan The District participates in the Orange County Employees Retirement System (“OCERS”), a cost- sharing multiple-employer defined benefit pension plan, which is governed and administered by a nine- member Board of Retirement. OCERS was established in 1945 under the provisions of the County Employees Retirement Law of 1937, and provides members with retirement, death, disability, and cost of- living benefits. All full-time and part-time District employees participate in OCERS. Contributions are based on an OCERS actuarial-determined rate structure and age at time of employment; contributions are deducted on a pre-tax basis. Most employees do not pay into Social Security with the exception of 1.45% of gross income, which is paid into the Medicare portion of Social Security. The amount of the retirement allowance is based upon the member’s age at retirement, the member’s “final compensation” as defined in Section 31462 of the Retirement Law of 1937, the total years of service under OCERS, and the employee’s classification as a Plan B, H or U member. Plan U applies to all full-time and part-time employees hired on or after January 1, 2013. Plan B applies to supervisor and professional employees hired on or after October 1, 2010, Local 501 employees hired on or after July 1, 2011 and OCEA employees hired on or after August 1, 2011. Plan H applies to employees hired on or after September 21, 1979 and prior to the eligibility dates for Plan B or Plan U. Plan H provides 2.5% of final compensation per year of service at age 55. Plan B provides 1.667% of final compensation per year of service at age 57.5, and Plan U provides 2.5% at 67. “Final compensation” is the highest consecutive 36 months of compensation divided by three for Plan B, H, and U members. Benefits fully vest under the OCERS retirement plan upon reaching five years of service. Employees who retire at or after age 50 with ten or more years of service are eligible to receive an annual retirement allowance, but at a reduced benefit for those employees retiring prior to age 67 for Plan U members, 57.5 for Plan B members, or prior to age 55 for Plan H members. OCERS also provides death and disability benefits. As a condition of participation under the provisions of the County Employees Retirement Law of 1937, members are required to contribute a percentage of their annual compensation to OCERS. The District contributes a portion of the employee’s contribution to OCERS for members of Plan H based on a percentage of the covered employee’s base salary. Members of Plans U and B do not receive any contributions toward employee contribution to OCERS. As of the December 31, 2024 valuation, OCERS had an aggregate Unfunded Actuarial Accrued Liability (“UAAL”) of approximately $4.6 billion, and a funded ratio of 83.8%. Set forth in Table 3 below is a current comparison of the District’s required contributions to OCERS for Fiscal Years 2020-21 through 2023-24 and projected required contributions for Fiscal Year 2024-25.

Actuarial valuation as of December 31, 2024 assumed an investment return of 7.00%, net of administrative and investment expenses. (2) Projected. Source: Orange County Sanitation District. As of December 31, 2024, the date of the most recent actuarial valuation completed by OCERS, the District’s past UAAL remained $0. The balance in the District’s UAAL deferred account as of December 31, 2024 was about $11.9 million. The balance in the District’s UAAL deferred account may be applied to the District’s Actual Future UAAL (but not normal contributions) in later periods. As of December 31, 2024, there was no transfer required from this account to pay off the District’s UAAL. The District has satisfied its past normal contributions from other funds, and currently intends to continue that practice. For the Fiscal Year ended June 30, 2025, total payroll costs of District employees covered by OCERS was $86,488,804. The District’s retirement program includes Additional Retiree Benefit Account (“ARBA”) benefits. ARBA benefits provide a monthly payment to retirees towards the premium costs of health insurance for the retiree and eligible dependents. The retiree is not required to use this amount for health insurance premium or to remain on the OCERS medical plan. Benefits vest upon retirement. The District pays 100% of the cost for the ARBA plan and utilizes a pay-as-you-go method for funding the plan. The District paid $1,268,650 in ARBA benefits during Fiscal Year 2024-25. For more information regarding OCERS and the District’s retirement plan as of June 30, 2024, see Note 6 to the Annual Comprehensive Financial Report of the Orange County Sanitation District for the Year Ended June 30, 2024 set forth in Appendix A. The Annual Comprehensive Financial Reports of the Orange County Employees Retirement System are available on the OCERS website at http://www.ocers.org. The information on such website is not incorporated herein by such reference or otherwise. The District cannot predict whether the OCERS investment portfolio will experience additional losses in the future; however, any future losses could result in material increases in the District’s required contributions. 298610182.5 22 Other Post-Employment Benefits In June 2015, Governmental Accounting Standards Board (“GASB”) issued Statement No. 75, which requires state and local governmental employers to recognize a liability as the employees earn benefits by providing services for its post-employment benefits other than pension benefits (known as other post-employment benefits or “OPEB”) and to recognize total OPEB liability if the OPEB is not administered through a trust that meets the specified criteria. Changes to OPEB liability are recognized immediately as OPEB expenses or deferred outflows/inflows of resources. The statement replaces the requirements of Statement No. 45. The District adopted Statement No. 75 for the fiscal year beginning July 1, 2017, as required of GASB. According to the District’s actuary, Demsey, Filliger & Associates (the “Actuary”), the unfunded OPEB liability as of July 1, 2024 was approximately $4.30 million. The District does not believe that its OPEB liability will have a material impact on its operational results. Risk Management As of the date hereof, the District has in force basic all risk property and casualty insurance, including theft, fire, flood, terrorism and boiler and machinery losses at its plants and pump stations. The District carries commercial cyber liability coverage. The District is self-insured for portions of workers’ compensation, property damage and general liability. The self-insurance portion of workers’ compensation is $1,000,000 per person per occurrence with outside excess insurance coverage to the statutory limit. The self-insured portion for property damage covering fire and other disasters is $500,000 per occurrence (for most perils) with outside excess insurance coverage to $1,000,000,000. The self-insured portion for property damage covering flood is $1,000,000 per occurrence with outside excess insurance coverage to $25,000,000. The District also maintains outside comprehensive boiler and machinery insurance with $100,000,000 limits and a $25,000 self-insured retention and business interruption insurance with $100,000,000 limits and a $500,000 self-insured retention. The District is self-insured for general liability coverage up to $1,000,000 per occurrence, with excess general liability coverage up to $40,000,000. The District is self-insured for pollution liability coverage up to $250,000 per loss, with outside pollution liability insurance coverage up to $10,000,000. In addition, the District has limited earthquake insurance partially covering several key structures; beyond that, the District relies on a combination of self-insurance and District reserves for all property damage from the perils of seismic activity as well as the expectation that some disaster relief funds may be available from the Federal Emergency Management Agency (“FEMA”) to address any resulting damage. See “DISTRICT REVENUES – Reserves” and “– Emergency Management: Response and Recovery.” There is no assurance that, in the event of a significant seismic event, a combination of self-insurance, District reserves or FEMA assistance would be available or sufficient for the repair or replacement of the affected property. During the past five fiscal years there have been no settlements in excess of covered amounts. Claims against the District are primarily processed by outside claim administrators or the District’s General Counsel. The District believes that there are no unrecorded claims as of June 30, 2025 that would materially affect the financial position of the District. For information regarding the District’s insurance coverage as of June 30, 2024, see Note 1 to the Annual Comprehensive Financial Report of the Orange County Sanitation District for the Year Ended June 30, 2024 set forth in Appendix A. 298610182.5 23 Existing Facilities The District’s existing facilities include two water reclamation plants, 15 off-plant pump stations, various interplant pipelines and connections, and ocean outfall facilities. The existing reclamation plants have a rated primary treatment capacity of 376 mgd, including standby capacity. The District’s collection system includes 12 trunk sewers consisting of approximately 388 miles of sewers in total. The District utilizes several phases for the treatment of wastewater. The first phase, preliminary treatment, removes any large debris as well as heavy, non-biodegradable materials (grit) such as sand and eggshells that could damage downstream treatment equipment. In the next phase, primary treatment, wastewater travels through large settling basins called clarifiers. These clarifiers allow for the separation of solids that either settle (sludge) or float (scum) from the wastewater. The collected solids are sent to solids treatment and handling facilities while the wastewater moves on to secondary treatment for further processing. See also “ - Biosolids Management” below. During secondary treatment, the wastewater is treated with naturally occurring microorganisms to remove most of the remaining dissolved and suspended organic solids. As part of the secondary treatment process, the sludge and scum are again collected and sent to solids treatment. All treated wastewater is then either provided to Orange County Water District (“OCWD”) for further treatment through the Groundwater Replenishment System (“GWRS”) or discharged via the ocean outfall system. A total of 130 mgd can be reclaimed by GWRS. See “ - Groundwater Replenishment System” below. Reclamation Plant No. 1 (“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. Influent wastewater entering Plant No. 1 passes through a flow metering and diversion structure, mechanical bar screens, grit chambers, and primary basins, before going to one of two secondary treatment processes –activated sludge or trickling filters. Secondary treated effluent is sent to the adjacent GWRS facility for tertiary treatment prior to reclamation and groundwater recharge. If OCWD is unable to accept these flows, this secondary effluent also can be diverted to the ocean discharge system described below. Solids treatment at Plant No. 1 includes co-thickening of primary and secondary sludge and scum, followed by anaerobic digestion and centrifuge dewatering resulting in the production of Class-B biosolids. Digester gas produced at Plant No. 1 is collected, cleaned, compressed, and distributed to Plant No. 1 Central Power Generation Facility as a renewable fuel for energy generation. In addition, Plant No. 1 includes facilities for odor control and chemical addition to support the aforementioned processes. Reclamation Plant No. 2 (“Plant No. 2”) is located in the City of Huntington Beach, 1,500 feet from the Pacific Ocean, at the mouth of the Santa Ana River. Influent wastewater entering Plant No. 2 passes through a flow metering structure and is separated into two distinct trains for treatment – reclaimable and non-reclaimable. Each train receives similar preliminary and primary treatment, passing through mechanical bar screens, grit removal chambers, and primary basins; however, secondary treatment for the two trains differs. Reclaimable flow utilizes trickling filters with solids contact basins whereas non- reclaimable flow passes through a pure-oxygen activated sludge process. Non-reclaimable flow is discharged to the ocean via the outfall pumping system and reclaimable flow is pumped to Plant No. 1 where it is combined with the secondary effluent flows from Plant No. 1 for tertiary treatment at the GWRS facility. Solids treatment at Plant No. 2 includes dissolved air flotation thickening, anaerobic digestion, and centrifuge dewatering resulting in the production of Class-B biosolids. Digester gas produced at Plant No. 2 is collected, cleaned, compressed, and distributed to Plant No. 2 Central Power Generation Facility as a renewable fuel for energy generation. Plant No. 2 also has facilities for odor control and chemical addition. 298610182.5 24 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. Based on the findings of a comprehensive assessment study completed in 2022, a rehabilitation project is in progress expected to ensure outfall reliability for many years to come. Outfall No. 1 serves as an emergency outfall and primary backup to Outfall No. 2. The District’s NPDES permit specifies that this outfall can be used only in the case of an emergency or during planned maintenance activities. The outfall system has two Santa Ana River Emergency Overflow Weirs at Plant No. 2, which discharge directly to the Santa Ana River. These weirs are for extreme emergency use only and serve as a secondary backup to the primary outfall facilities, ensuring the safety and welfare of the community at large. Set forth in Table 4 below are the reclamation plants’ approximate treatment capacities. Table 4 Wastewater System Treatment Capacities (mgd) As of June 30, 2025 2024-25 Actual Flows Primary Treatment Capacity Secondary Treatment Capacity Plant No. 1 117 208 182 Plant No. 2 67 168 150 Aggregate Treatment 184 376 332 ____________________ Source: Orange County Sanitation District. The District also has the capability to divert a portion of the influent flow from Plant No. 1 to Plant No. 2 through interplant connections. A portion of the flow destined for Plant No. 2 can also be diverted to Plant No. 1 instead via structures located throughout the collection system. Another interplant facility allows gas generated during solids treatment described above to be transported between Plant No. 1 and Plant No. 2 and allows digester gas (which is used as fuel for many of the facilities’ engines) from one plant to be used at the other to balance the supply and demand, which results in more efficient gas utilization compared to use isolated by plant. This optimization allows the District to produce enough electricity to meet two-thirds of the power needed to run both Plant No. 1 and Plant No. 2. Permits, Licenses and Other Regulations The District is subject to laws, rules and permits issued by federal, state, regional and local regulatory bodies. The Wastewater System is subject to regulations imposed by the 1972 Clean Water Act, as amended (the “Clean Water Act”), the California Environmental Quality Act of 1970, as amended (“CEQA”) and the Federal Clean Air Act (the “Clean Air Act”). Regulatory requirements to conform with these laws are primarily administered by the United States Environmental Protection Agency (the “EPA”), the California Air Resources Board (“CARB”), the Santa Ana Regional Water Quality Control Board (“RWQCB”), and the South Coast Air Quality Management District (“AQMD”). These agencies regulate the standards of quality of water or air that can be discharged or emitted from the reclamation plants and their processes as well as pump stations. The Clean Water Act directs the EPA to monitor and regulate the discharge of pollutants into the waters of the United States, including a requirement that all wastewater treatment plants provide primary and secondary treatment. In 1977 Congress amended the Clean Water Act to allow modification (so-called “waivers”) of secondary treatment standards for certain ocean dischargers, 298610182.5 25 if they could demonstrate to the satisfaction of the EPA that no adverse environmental impacts would occur. Similarly, in 1990, Congress amended the Clean Air Act to establish the Title V federal operating permit program and technology-based control requirements for hazardous air pollutants. The District currently has all applicable permits and licenses necessary to operate its facilities. Since the passage of the Clean Water Act the District has discharged treated wastewater into the Pacific Ocean under a permit issued by the EPA and the RWQCB. The discharge permit included a modification under the Section 301(h) provisions of the Clean Water Act, allowing for less than full secondary treatment based on an ocean discharge of sufficient depth, distance, and dilution. The permit was initially issued in 1985 and was the first modified Section 301(h) permit issued to a major wastewater treatment facility. The permit was re-issued on May 6, 1998 and expired on June 8, 2003. On July 17, 2002, the Board of Directors adopted Resolution No. OCSD 02-14, “Establishing the Policy for Level of Treatment of Wastewater Discharged into the Ocean.” This resolution established the District’s policy to treat all wastewater discharges into the ocean to secondary treatment standards, thereby providing for continued public safety, marine ecosystem protection, and water reclamation opportunities. To implement this policy, the District’s staff was directed to immediately proceed with the planning, design and implementation of treatment methods that will allow the District to meet Clean Water Act secondary treatment standards with the expressed purposes of eliminating the need for the permit modification received under Section 301(h). Following Resolution No. OCSD 02-14, the District withdrew its Section 301(h) waiver and prepared a National Pollutant Discharge Elimination System (“NPDES”) Permit Application. The District submitted its application to the EPA and the RWQCB and received an NPDES permit on October 31, 2004, requiring the District to meet secondary treatment levels in accordance with a time schedule order (“TSO”). The District completed these improvements ahead of the TSO in December 2012 at a total capital improvement cost of $537.8 million. As required, the District has submitted multiple permit renewal applications. The current NPDES permit (Order No. R8-2021-0010, NPDES No. CA0110604) went into effect on August 1, 2021 and will remain in effect through July 31, 2026. An NPDES renewal application will be submitted to the EPA and the RWQCB no later than January 31, 2026. The District is also subject to the requirements of the Clean Air Act, which mandates attainment with national ambient air quality standards for criteria pollutants (ozone, particulate matter, carbon monoxide, lead, nitrogen dioxide, and sulfur dioxide). Air pollutants cause adverse effects on human health and environment. The AQMD is the local air pollution control agency charged with implementing the Clean Air Act. In addition to mandated criteria pollutants, the AQMD also implements numerous federal and State requirements related to toxic air pollutants which can cause cancer or other severe localized health effects. For example, the State’s Air Toxic Hot Spots Act (Assembly Bill 2588) requires facilities to conduct health risk assessments and notify the neighboring communities if the health risk exceeds the regulatory thresholds established by the local air pollution control district. Pursuant to AQMD’s requirements, the District must obtain permits before capital improvement projects can be constructed and operated as well as any project that has the potential to emit air contaminants. Such permits are project-specific and may contain conditions that govern design criteria, operating parameters, and emissions standards. In accordance with 40 C.F.R. § 63, Subpart VVV, the District’s treatment facilities are enclosed to capture and treat emissions to ensure regulatory emissions standards are met and to minimize odor impact to the neighboring communities. The District’s treatment plants are also subject to the stringent requirements of Title V of the 1990 Clean Air Act amendments. The Title V permit is a federally enforceable permit that consolidates all the air permits issued to a major source 298610182.5 26 facility. The permit contains all applicable local, state, and federal requirements, including periodic self- certification of compliance and mandatory self-reporting of permit deviations. All Title V permit-related reporting and documents submitted to the AQMD must be signed by the highest responsible official – in this case, the General Manager. The Title V program also demands facilities to organize and execute extensive training of the staff involved, including the field operation and maintenance staff. An important feature of the Title V program is the possibility of active public participation and intervention through the ability to speak at public hearings. The District received the initial Title V permits for the reclamation plants in January 2009. Title V permits are issued for a five-year period. Title V permits for both plants were renewed/re-issued in April 2014, and again in September 2020 (Plant No. 1) and October 2020 (Plant No. 2). Permit applications for the current renewal period have been submitted for both plants and are pending reissuance from the AQMD. District Planning The Board of Directors has adopted a comprehensive Strategic Plan that encompasses the District’s service levels and operational needs. The Strategic Plan is updated biennially and is the first step of a two- year, four-step management process that creates and maintains both the vision and alignment between the Board of Directors, staff, and the public that the District serves. See “THE DISTRICT — Strategic Planning.” In December 2017, the Board of Directors adopted a Facilities Master Plan that has served as the foundation of the District’s subsequent planning efforts. The District has since implemented a more robust Asset Management Program to maintain and improve its planning efforts. This program develops an annual asset management plan that highlights asset conditions; current issues; and the planned studies, projects, and initiatives that will ensure that District facilities are reliable, meet current and future needs, and achieve the levels of service adopted by the Board of Directors. Capital Improvement Program The District maintains and annually updates a phased 20-year capital improvement program (“CIP”) made up of a series of projects to allow the District to maintain reliability and accommodate future growth, as well as meet future regulatory requirements, level of service goals, and strategic initiatives. The District’s Asset Management Program is continually assessing the condition of existing assets and systems to ensure that they provide the necessary level of service. The District expects to accomplish the following as part of the CIP over the next 20 years: • Major rehabilitation or replacement of facilities and components used in all stages of the treatment process - preliminary, primary, secondary, and solids treatment, outfall pumping and discharge system, and central generation at both reclamation plants; • Implementation of the recommendations of the Biosolids Master Plan to address seismic risks, improve biosolids quality and accept food waste; • Replacement of the Plant 2 Operation and Maintenance facilities; • Upgrade of the Supervisory Control and Data Acquisition (“SCADA”) system and network at Plant No. 2, replacement of the process control systems, uninterruptible power supply (“UPS”) system, and electrical power distribution system at both reclamation plants; • Implementation of the recommendations of the Climate Resiliency Study and Seismic Evaluation Study to withstand or adapt to adverse conditions such as heavy rains, flooding, 298610182.5 27 sea level rise, earthquakes, tsunamis, extreme heat, wildfires and electrical grid interruptions; • Replacement or rehabilitation of plant-wide infrastructures, such as buried process piping, tunnels and junction structures; • Replacement or rehabilitation of District’s outlying pumping stations, including the abandonment and/or demolition of two pump stations; • Rehabilitation of aging trunk sewers and manholes; • Reduction of fence line odor to levels that minimize odor complaints; and • Safety improvements at both reclamation plants. The CIP is reviewed, validated and updated annually to ensure that all capital projects’ scopes of work and cost estimates are up-to-date. Through the budget validation process, each project’s schedule, staff resources, total project costs, cash flow and risks are assessed to confirm budgetary needs. The most recent CIP validation effort resulted in revisions to the CIP. As of June 30, 2025, the CIP included 74 active projects and five programs (Capital Equipment, Information Technology Capital Program, Planning Studies Program, Research Program and Small Construction Projects Program) with a total CIP budget authority of over $3.5 billion. That budget authority excludes future rehabilitation and replacement and CIP savings and deferrals. Set forth in Table 5 below is a summary of total CIP outlays (including future rehabilitation and replacement and net of savings and deferrals) over the Fiscal Years 2025-26 through 2034-35. Of this ten-year, $3.6 billion portion of the CIP program, $289.0 million of CIP outlays are budgeted in Fiscal Year 2025-26. Also budgeted in a separate contra line item are anticipated offsetting CIP savings and deferrals of $34.7 million, thereby reducing the net budgeted outlays to $254.3 million for Fiscal Year 2025-26. Table 5 Net Capital Improvement Program Outlays Fiscal Years 2025-26 through 2034-35 Project Cost Capital Project Costs $3,541,768,199 Future Rehabilitation and Replacement 497,988,762 CIP Savings and Deferrals (484,770,835) Total Validated Capital Improvement Program $3,554,986,126 ____________________ Source: District Budget Update – Fiscal Year 2025-26. The District currently expects to fund the current CIP with Revenues and other funds, and does not currently expect to issue Obligations for such purposes. The CIP is subject to change, and the District may determine to fund all or a portion of the CIP from Obligations. Groundwater Replenishment System The District has taken a multi-jurisdictional approach to planning for capital facilities because many of the methods for reducing or managing flows involve other jurisdictions. One such project is the GWRS. In March 2001, the District entered into an agreement with the OCWD to design and construct the GWRS. The capital cost of this phase was shared equally (50% shares) by each agency. The GWRS is a joint effort by the two agencies to provide reclaimed water for replenishment of the Orange County Groundwater Basin 298610182.5 28 and to augment the seawater intrusion barrier. The GWRS became operational in January of 2008 producing 70 mgd of highly purified water. The Initial Expansion of the GWRS broke ground in January 2012 to add approximately 30 mgd of production capacity and was completed in June 2015, resulting in purifying 100% of the treated wastewater from the District’s Fountain Valley-based Plant No. 1. The Initial Expansion of the GWRS was funded solely by OCWD. In 2016, the District and OCWD completed a $2 million joint study to explore the Final Expansion of the GWRS which would increase GWRS capacity by an additional 30 mgd. The study identified an implementation plan to convey secondary effluent from the District’s Plant No. 2 in Huntington Beach using new and existing infrastructure to support the GWRS Final Expansion. The GWRS Final Expansion was funded solely by OCWD and Final Expansion of the GWRS was completed in 2023. Biosolids Management Through the treatment of wastewater, the District treats and recovers valuable nutrient-rich, organic matter to produce biosolids. Consistent with federal, State and local regulations, the District’s biosolids are recycled through composting, fertilizing non-food farm fields (land application), and drying and pyrolyzing (to produce fertilizing pellets and biochar). The District aligns its biosolids management strategy with market conditions to sustain an environmentally responsible, resilient and cost-effective biosolids management program. On average, the District produced 508 tons per day (“tpd”) of biosolids in Fiscal Year 2024-25, with a total expenditure of 97% of the $14.4 million budgeted, at an annual average cost per ton of $75.66 for hauling and management at offsite locations, as described in the following table. The overall tonnage decreased in 2019 after the new solids centrifuge facilities became operational, which significantly reduced biosolids hauling and management costs. In addition, in September 2021 the Irvine Ranch Water District’s solids discharge to the District effectively ceased after commissioning its own solids processing facilities.

In combination, these options provide capacity to manage more than ten times the District’s daily biosolids production to ensure continuity of operations. The District’s biosolids management contracts do not guarantee biosolids tonnage and are typically interim-term contracts with five (5) one-year renewal options, for a maximum contract term of 10 years. In May 2017, the District completed its Biosolids Master Plan that included an evaluation of existing solids handling facilities, assessment of solids treatment alternatives, recommendations for future capital facilities’ improvements, identification of alternative biosolids products that meet sustainable and beneficial reuse markets and plans for a high-strength organic (food waste slurry) co-digestion facility. The Biosolids Master Plan will serve as the roadmap over a 20-year planning period (until 2037). Urban Runoff To mitigate pollution caused by urban runoff impacting the beaches in north-central Orange County, the District’s Board of Directors adopted a number of policy resolutions to accept dry weather 298610182.5 30 urban runoff into the District’s wastewater treatment system for treatment, beneficial reuse and disposal. Resolution No. 01-07, adopted by the District’s Board of Directors on March 28, 2001, declared that the District would initially waive fees and charges associated with authorized discharges of dry weather urban runoff to the sewer system until the total volume of all runoff discharges exceeds 4 mgd when calculated as a monthly average. In June 2002, Assembly Bill 1892 amended the District’s legal authority to permit the diversion and management of dry weather urban runoff flows. For the first 12 years of the Dry Weather Urban Runoff Program, the average monthly flow remained below 4 mgd. In 2012, the District received a number of diversion proposals to address bacteria and selenium levels in the upper Newport Bay. To accommodate the additional diversions and enhance beach water quality improvement, the Board of Directors adopted Resolution No. 13-09 on June 12, 2013 to expand the waiver of fees or charges on the treatment of dry weather urban runoff from 4 mgd to 10 mgd. This change was essential to treat the increased volume of dry weather runoff, protecting Orange County’s coastal resources, public health and local economy. The Dry Weather Urban Runoff Program is administered by the District’s Environmental Services Department’s Resource Protection Division, which issues a discharge permit for each of the diversion structures. The permit serves as a control mechanism that prohibits the discharge of wet weather runoff and only permits the discharge of urban runoff during dry weather conditions. The permit establishes specific discharge limits and outlines requirements for contaminant monitoring and flow metering by the discharger. The District also conducts routine verification sampling and analysis to ensure compliance. There are currently 21 active dry weather urban runoff diversion structures. Four are owned by the County of Orange and operated by its employees; 11 by the City of Huntington Beach; two by the City of Newport Beach; three by the Irvine Ranch Water District; and one by the [Irvine Company, the owner of The Resort at Pelican Hill]. The Santa Ana-Delhi Dry Weather Urban Runoff Discharge permit was added to the program on January 1, 2024 and is the largest among all 21 diversions. Emergency Management: Response and Recovery Emergency Response Programs. In recognition of the potential damage which could occur in the event of a major earthquake, flood, or other disaster, the District implemented an Integrated Emergency Response Program (the “IERP”) in 1979. The IERP contains policies, plans and procedures preparing for, and responding to, emergencies. In 2020, the District updated the IERP to align with standards set by FEMA’s National Incident Management System. The IERP is organized into Functional and Situational Annexes which guide the District’s response to man-made and natural disasters. Functional Annexes align with FEMA’s Emergency Support Functions (“ESFs”). Functional Annexes include logistics, communications, operations, maintenance, engineering, emergency management, cybersecurity, recovery, environmental, health and medical services, hazardous materials response, security and public affairs. These are discipline-specific groups that develop Functional Annexes to describe goals, objectives, operational concepts, capabilities, organizational structures and replaced policies and procedures. Situational Annexes are developed for each of the hazard responses that are likely or could possibly occur at the District. Situational Annexes include earthquake, power outage, pandemic event, fire, tsunami, atmospheric hazard, hazardous materials spill or release, man-made physical disruption, man-made technological disruption, flood, landslide, coastal erosion, extreme weather, severe storm, high winds, severe thunderstorm and drought. These Annexes stipulate certain actions to be taken by individuals at the time of the incident. For example, the District’s High Flow Emergency Response Plan is included as an Annex in the IERP. This plan is based on a color code system from blue to yellow to orange to red and then 298610182.5 31 purple that identifies specific actions to be taken by staff in response to expected and actual increasing flow coming into the District’s reclamation plants and collection sewers. The District believes that wastewater collection, treatment and disposal systems typically undertaken in anticipation of normal wet weather should be able to withstand, for example, an “expected/average” El Nino event without significant disruption. While no assurances can be given, the District believes that the likelihood of a system failure is low due to the operational readiness of all of its equipment and the District’s high level of equipment redundancy. To ensure continued effectiveness, alignment with best practices, and responsiveness to evolving threats, the IERP is reviewed and updated every three years. This regular review cycle supports the District’s commitment to operational resilience and public safety. Master Plan & Studies. The District has analyzed disaster preparedness issues and policies within the Master Plan and the 1994 report titled Fault Rupture Hazard Investigation – Wastewater Treatment Plant No. 2 (the “1994 Report”). The disaster preparedness plan included in the Master Plan reviewed two major earthquake scenarios: an 8.3 Richter magnitude (“M”) earthquake on the southern San Andreas fault system and an M 7.0 earthquake on the Newport-Inglewood fault zone, which includes Plant No. 2. While the San Andreas event would be more destructive overall, the Newport-Inglewood fault poses a more direct threat to the District’s facilities due to its proximity. The Master Plan concluded that it would not be economically feasible to retrofit all existing sanitary sewerage facilities to withstand such an event. Instead, it recommended a risk reduction program involving targeted retrofits and structural reviews of facilities built prior to modern seismic standards. Since then, the District has significantly expanded its seismic and geotechnical preparedness through a series of advanced studies and capital projects. A three-tier seismic vulnerability assessment was conducted of selected buildings and water-bearing structures at both Plant No. 1 and Plant No. 2, identifying structural deficiencies and informing retrofit strategies. Building on this foundation, later projects further evaluated seismic vulnerabilities and guided the design of resilient infrastructure. These efforts are operationalized through certain capital improvement projects, which outline construction and inspection roles for seismic upgrades and the installation of a sea wall capable of withstanding seismic forces and tsunamis. In parallel, a 2024 Kleinfelder fault hazard report provided a modern fault hazard assessment for Plant No. 2, identifying active fault traces and recommending no-build zones for critical infrastructure based on trenching and geophysical data. These findings represent a significant update to the 1994 Report, incorporating current geological methodologies. District requirements and civil design criteria embed geotechnical and seismic considerations into design standards, including grading, drainage, and foundation requirements. Structural design criteria further mandate compliance with the latest California Building Code with seismic provisions for essential facilities. Collectively, these efforts reflect the District’s evolution from foundational hazard identification to a proactive, code-aligned, and technically rigorous approach to seismic and geotechnical resilience. The District has completed retrofitting where deemed appropriate, and all recent and future projects are designed to the same high earthquake code standards as essential services like hospitals and fire stations. Many older buildings analyzed in the Master Plan have since been replaced with post-1989 structures. Additionally, the Army Corps of Engineers’ “All-River Plan” has mitigated future flooding risks from the Santa Ana River system, further protecting the District’s wastewater infrastructure. Multi-Jurisdictional Hazard Mitigation Plan. The District is an active participant and member agency in the Orange County Water and Wastewater Multi-Jurisdictional Hazard Mitigation Plan (“MJHMP”). Since the plan’s inception in 2007, the District has played a key role in the regional effort to 298610182.5 32 identify hazards, assess vulnerabilities and implement strategies that reduce the risk of disasters affecting public health, infrastructure and the environment. As a member agency, the District contributes data, expertise and planning resources to ensure the MJHMP reflects the unique risks and operational priorities of wastewater management across central and northwest Orange County. The MJHMP is updated approximately every five years, with the most recent update completed in 2024. During each planning cycle, the District forms an internal hazard mitigation planning team and collaborates with other agencies, consultants and the public to revise and refine the plan. The District’s annex within the MJHMP outlines its specific hazard exposures, such as seismic shaking, flooding, and power outages, and details mitigation actions tailored to its infrastructure and service area. These updates help the District maintain eligibility for federal funding through FEMA and ensure its emergency preparedness strategies remain aligned with evolving threats and best practices. In the 2024 update to the MJHMP, the District outlined a comprehensive set of mitigation actions aimed at strengthening the resilience of its wastewater infrastructure against a range of natural and human- caused hazards. These actions focus on protecting critical assets, including 396 miles of pipeline, two reclamation plants, and ocean outfall systems that serve approximately 2.6 million residents. Recognizing the threats posed by seismic activity, flooding, power outages and cyberattacks, the District implemented measures such as seismic retrofitting for vulnerable facilities, flood protection upgrades in low-lying areas, and the installation of backup generators to maintain operations during emergencies. The District also prioritizes cybersecurity enhancements to safeguard its digital control systems and conducted public outreach campaigns to promote community preparedness. Additionally, the District integrates hazard exposure data into its capital planning to ensure future infrastructure investments account for potential risks. These coordinated mitigation efforts not only reduce the likelihood of service disruption during disasters but also position the District to access federal and state funding, such as FEMA mitigation grants, that support long-term resilience and infrastructure improvements. Strategic Planning The District maintains a Strategic Plan, which was most recently updated in November 2023, to address future service levels and operational needs. The Strategic Plan is currently being updated for Board of Directors adoption expected in November 2025. The Strategic Plan envisions an organizational culture that adheres to the District’s Core Values and makes efficient and effective use of all available resources. The District is committed to focusing efforts on customer service, protecting public health and the environment, fiscal responsibility, communications, partnering with others, and creating the best possible workforce. The Strategic Plan is broken down into four categories with 15 policy areas that define District responsibilities and services. The 2025 update would include a 16th policy area under Environmental Stewardship. These areas are:  Business Principles o Budget Control and Fiscal Discipline – have practices and safeguards in place to ensure the District’s long-term fiscal stability o Asset Management – assess and manage the collection system and treatment plant systems and assets to improve resilience and reliability while lowering lifecycle costs 298610182.5 33 o Cybersecurity and Artificial Intelligence – maintain adequate cybersecurity techniques that protect computer assets, networks, programs, data, and industrial control equipment from unauthorized access, denial of service, or attacks o Property Management – identify and protect all District property rights to assure that assets are not encumbered or encroached upon so that the facilities may be properly operated, maintained, upgraded, and replaced o Organizational Advocacy and Outreach – maintain stakeholders informed to garner support for services while protecting the District’s interest with legislative oversight  Environmental Stewardship o Energy Independence – strive to be energy neutral; maximize electrical, thermal, and methane gas generation; minimize energy utilization using sound engineering and financial principles o Climate and Catastrophic Event Resiliency – 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 o Food Waste Treatment – collaborate with local agencies and waste haulers to find ways to beneficially reuse food waste to assist cities in our service area in meeting their diversion requirements while increasing the District’s energy production o Water Reuse – seek to beneficially reuse all reclaimable water for potable, industrial, irrigation and environmental uses o Environmental Water Quality, Stormwater Management and Urban Runoff – partner with stormwater permittees to accept up to 10 million gallons per day of dry weather urban runoff at no charge to improve water quality in streams, rivers and beaches as long as the constituents within the flow do not adversely impact the District’s worker safety, treatment processes, reuse initiatives, or permit compliance o Potable Water Salinity Control (as of 2025) - partner with other public agencies in our watershed to reduce the salinity of the potable water supply of our stakeholders  Wastewater Management o Chemical Sustainability – identify chemicals key to District operation, investigate the market risks for those chemicals and devise strategies to mitigate identified risks to availability and pricing o Biosolids Management – remain committed to a sustainable biosolids program and beneficially reuse biosolids o Constituents of Emerging Concern – 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 at the federal, state, and regional levels  Workplace Environment o Resilient Staffing – attract, develop and retain high-quality talent to support its mission of protecting public health and the environment 298610182.5 34 o Safety and Physical Security – 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 the District’s property and physical assets Climate Issues Numerous scientific studies on climate change show that, among other effects on the global ecosystem, sea levels will rise, extreme temperatures, will become more common, and extreme weather events will become more frequent as a result of increasing global temperatures attributable to atmospheric pollution. Sea levels will continue to rise in the future due to the increasing temperature of the oceans causing thermal expansion and growing ocean volume from glaciers and ice caps melting into the ocean. Coastal and low-lying areas like portions of the District’s service area and facility locations are at risk of substantial flood damage over time, affecting private development and public infrastructure, including roads, utilities, emergency services, schools, and parks. Certain portions of these coastal areas are also at elevated risk to damage from tsunami. The District commissioned a Climate Resiliency Study that was completed in November 2019 and provides a comprehensive analysis of climate-related, site-specific risk assessments of the District’s facilities using available climate predictions, industry standards, and geographical information systems. The purpose of the study was to help improve the resiliency of District facilities and incorporate adaptation strategies in the design and construction of future projects. The District continues to monitor potential risks related to climate change by routinely working with the City of Huntington Beach and the City of Newport Beach to understand and quantify the risk of tsunami inundation. In addition, the District routinely updates design guidelines based on the latest California Climate Assessment reports, FEMA flood maps, and American Society of Civil Engineering standards for flood resistant design and construction to ensure the study recommendations remain aligned with evolving climate science and regulatory expectations. District policy aims to design, maintain, and operate 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 heavy rains, flooding, sea level rise, earthquakes, tsunamis, extreme heat and wildfires. The Climate Resiliency Study determined that risk to District assets from wildfire, extreme heat, and wind are low, so adaptation strategies to protect assets from these climate impacts were not considered. The vulnerability assessment identified Plant No. 2 and some pump stations located along the coast and flood channels to be vulnerable to tsunami and flooding due to sea-level rise. At Plant No. 2, the recommendation is to install a flood wall along Brookhurst Street and the Talbert Marsh to protect the plant against a 100-year flood (with sea-level rise projected to 2070) as well as a tsunami up to 10 feet. As for the pump stations, the recommendation is to employ building-level adaptations such as stop logs over doors and watertight hatches to protect vulnerable equipment inside the pump stations. These recommended improvements are underway, with implementation planned in phases over time. The budget for the implementation of these recommendations has been incorporated into the District’s 20-year CIP. While the District’s efforts aim to improve the resiliency of its facilities, natural disasters and other natural forces are not entirely predictable and may, nonetheless, result in material damage to District facilities. Climate change and natural forces may damage other property in the District’s service area or impose new or larger economic costs, leading to negative impacts on the local economy. As a result, the District may experience negative impacts on service revenues and ad valorem tax revenues or increased 298610182.5 35 District costs that could have a material adverse effect on the business operations or financial condition of the District. In addition, climate change or natural forces may damage other properties in the District’s service area and lead to negative impacts on the local economy. As a result, the District may experience a combination of reduction of service revenues and ad valorem tax revenues and increased operational costs that could have a materially adverse effect on the business operations and financial condition of the District. Additionally, climate change and other environmental concerns have led, and may continue to lead, to new laws and regulations at the federal and state levels (including but not limited to air, water, hazardous substances and waste regulations) that could have a materially adverse effect on the operations and financial condition of the District. DISTRICT REVENUES Sewer Service Charges General. The District has the power to establish fees and charges for services of the Wastewater System. Such fees and charges are established by the District’s Board of Directors and are not subject to review or approval by any other agencies. In Fiscal Year 1997-98, a Rate Advisory Committee (the “RAC”) was established comprised of representatives from industrial, commercial and residential users. The goal of the RAC was to examine the then-current rate structure and, if needed, develop recommendations for change. The RAC analyzed the District’s rate structure to determine whether its then current sewer service user fees (now known as “Sewer Service Charges”) were equitable among residential and industrial customers. This review resulted in a proposal to expand the number of non-residential user categories from one to 23 and to provide for gradual rate increases in seven of the nine Revenue Areas. The Sewer Service Charges for those categories were based on the average flow and strength of wastewater discharged for each property type and remain currently in use. The Board of Directors establishes the annual sanitary sewer service charges by ordinance. The sanitary sewer service charge ordinances are adopted by a two-thirds vote of the Board of Directors as required under law after conducting a noticed public hearing in compliance with Proposition 218. See “LIMITATIONS ON TAXES AND REVENUES – Article XIIIC and Article XIIID of the California Constitution.” The District collects Sewer Service Charges from property owners through the semi-annual property tax bill distributed by the County throughout the District, except in Revenue Area No. 14. Pursuant to the IRWD Agreement, the District receives quarterly fee payments from the IRWD which directly collects fees from customers through a monthly billing procedure in Revenue Area No. 14. The District currently participates in the County’s Teeter Plan under which the District receives annually 100% of the secured property tax levies to which it otherwise is entitled, regardless of whether the County has actually collected the levies. The District has covenanted in the Master Agreement to fix, prescribe and collect fees and charges to satisfy certain coverage requirements as further described under “SECURITY AND SOURCES OF PAYMENT FOR THE REVENUE OBLIGATIONS – Rate Covenant” herein. Residential and Commercial Sewer Service Charges. In December 2022, the Board of Directors authorized a Proposition 218 notice on proposed rate increases for each year over the next five years. Pursuant to the adoption of Ordinance No. OC SAN-58 on March 22, 2023, which was amended by the adoption of Ordinance No. OC SAN-58A on June 28, 2023 (together, “Ordinance No. OC SAN-58”), the District established residential Sewer Service Charges, except within Revenue Area No. 14, based on the 298610182.5 36 cost of services and facilities provided to each customer of the District. The noticed public hearings held in connection with the adoption of Ordinance No. OC SAN-58 considered an increase in the single-family residential rate, the underlying rate for all of the District’s sewer service charges, of 3.5% for Fiscal Year 2023-24 through Fiscal Year 2027-28. These increases were approved by the Board of Directors through the adoption of Ordinance No. OC SAN-58. In December 2022, the District issued a final report related to a rate study of the wastewater rates, fees and charges. The study includes development of cost based regional wastewater service rates, capital facility capacity charge, supplemental capital facility charge, and ancillary charges provided to District customers over a 5-year period beginning July 1, 2023. The rate study recommends an overall level increase of 3.5% annually over that 5-year period.

The District’s SFR rate of $384 for Fiscal Year 2025-26 remains below the average annual sewer rate of about $612 according to the National Association of Clean Water Agencies 2024 Cost of Clean Water Index. The average annual sewer rate for Region 9 which includes California, Nevada and Arizona is $523. Industrial Sewer Service Charges. The District charges industrial Sewer Service Charges to customers discharging high-strength or high-volume wastes into the sewer systems. Customers subject to industrial Sewer Service Charges are billed directly by the District. The fee charged to each customer is based on the customer’s sewage volume, the concentration of suspended solids and biochemical oxygen demand. Total industrial Sewer Service Charges in Fiscal Year 2024-25 were approximately $14.8 million. The Sewer Service Charge increases described above are necessary to meet the District’s cash flow needs arising from the addition of disinfection treatment and other operating requirements. Additional Revenues The District has several sources of additional revenue, including property taxes, Capital Facilities Capacity Charges, capacity rights, permit and inspection fees and interest earnings. Property Taxes. The District receives approximately 2.5% of the one percent County ad valorem property tax levy, based on the allocation procedure under State law. Property tax revenues were $110.2 million in Fiscal Year 2020-21, $119.2 million in Fiscal Year 2021-22, $125.5 million in Fiscal Year 2022-23, $131.6 million in Fiscal Year 2023-24 and $138.3 million in Fiscal Year 2024-25. The District currently estimates that its property tax receipts will increase by approximately 3.0% each year through Fiscal Year 2034-35. The apportionment of the ad valorem tax is pursuant to the Revenue Program adopted in April 1979 to comply with regulations of the EPA, the State Water Resources Control Board and Board of Directors’ policy. 298610182.5 39 Capital Facilities Capacity Charges. Capital Facilities Capacity Charges (commonly referred to as connection fees) are one-time fees with two components, paid at the time property is developed and connected to the Wastewater System. The fees are imposed by the District pursuant to Section 5471 of the California Health and Safety Code and are levied to pay a portion of the District’s capital costs and for access to capacity in the Wastewater System. The District currently has Capital Facilities Capacity Charges of $6,529 per residential unit (base rate for three-bedroom, with other unit sizes having a rate that is a percentage of the base rate depending on the size of the unit); however, under the current industrial use ordinance, additional Capital Facilities Capacity Charges can be imposed on industrial users who place larger than average demand on the Wastewater System and certain units are exempt based on state law (i.e., junior additional dwelling units). Member cities and sanitary districts collect Capital Facilities Capacity Charges for the District when building permits are issued. Capital Facilities Capacity Charges are reviewed annually to reflect the changes in the value of the Wastewater System to which a new customer is connecting. On December 15, 1999, the Board of Directors approved District Ordinance No. OCSD 11 (the “1999 Ordinance”) which established a comprehensive Capital Facilities Capacity Charge. The 1999 Ordinance, effective as of January 1, 2000, renamed connection fees as Capital Facilities Capacity Charges and provided a more equitable schedule of fees among industrial, commercial and residential users. Pursuant to the 1999 Ordinance, Capital Facilities Capacity Charges were revised for high demand industrial users in five incremental increases from 1999 through 2001. Capital Facilities Capacity Charge rates have been further amended by ordinances enacted over time. For a summary of historical and projected revenues derived from Capital Facilities Capacity Charges, see Table 14 and Table 15 below. Pursuant to an agreement with the IRWD, the IRWD is not required to pay Capital Facilities Capacity Charges and, in exchange, the IRWD provides funding to the District for the construction costs of certain wastewater collection, transmission, treatment and disposal facilities to be used by the IRWD and is obligated to make certain payments to the District for certain services arising from the Wastewater System (including any standby or availability charges). Sale of Capacity. The District has entered into agreements with the Santa Ana Watershed Project Authority (“SAWPA”) whereby wastewater from Upper Santa Ana River Basin dischargers can be transported through the District’s Santa Ana River Interceptor to the District’s wastewater treatment facilities. This program was developed in the early 1970s. The agreements establish control mechanisms regarding the quality of wastes deposited into the Wastewater System. At the present time, SAWPA has purchased and paid for 30 mgd of maximum regulated flow capacity rights in the District’s Santa Ana River Interceptor and 17 mgd of monthly average flow capacity in the District’s wastewater treatment plants. Projected revenues from SAWPA are estimated to be approximately $3 million annually over the next five years. Additional treatment plant capacity can be purchased in increments at the District’s current replacement cost. Federal Subsidy Payments. In connection with the District’s Revenue Obligations, Series 2010A (the “2010A Revenue Obligations”) and the District’s Revenue Obligations, Series 2010C (the “2010C Revenue Obligations”), issued as “Build America Bonds,” the District currently is scheduled to receive certain federal subsidy payments of approximately $1.9 million annually through 2031 and lesser amounts thereafter until 2044. Subsidy payments with respect to the 2010A Revenue Obligations and the 2010C Revenue Obligations constitute Revenues as defined in the Master Agreement. In its financial reports, the District accounts for subsidy payments received in connection with the 2010A Revenue Obligations and the 2010C Revenue Obligations as a reduction in interest expense with respect to such obligations. For the 2010A Revenue Obligations and the 2010C Revenue Obligations to be and remain Build America Bonds, the District must comply with certain covenants and establish certain facts and expectations 298610182.5 40 with respect to the 2010A Revenue Obligations and the 2010C Revenue Obligations, the use and investment of proceeds thereof and the use of property financed thereby. Thus, it is possible that the District may not receive the federal subsidy payments due to the District’s noncompliance. The federal subsidy payments are also subject to offset against amounts that may, for unrelated reasons, be owed by the District to any agency of the United States of America. On March 1, 2013, the federal government announced the implementation of certain automatic spending cuts known as the sequester (the “Sequester”). As a result of the Sequester, aggregate federal subsidy payments for the 2010A Revenue Obligations and the 2010C Revenue Obligations were reduced by amounts ranging from $220,679 to $373,955 in each federal fiscal year ended September 30, 2013 through 2022, with annualized reduction rates ranging from 5.7% to 8.7%. Currently, the federal subsidy payments for each federal fiscal year through the federal fiscal year ending September 30, 2031 will be reduced at a rate of 5.7% annually. The District is obligated to make all payments with respect to the 2010A Revenue Obligations and the 2010C Revenue Obligations from Revenues as defined in the Master Agreement, regardless of whether it receives the full amount of federal subsidy payments. The District cannot predict whether future reductions in federal subsidy payments will occur due to the Sequester. Wastewater Treatment History The wastewater flows for Fiscal Year 2020-21 through Fiscal Year 2024-25 were 182 mgd, 179 mgd, 186 mgd, 193 mgd and 184 mgd, respectively. The highest flow rate experienced during these years was in February 2024, when a peak flow of 493 mgd was recorded. There were no sewer failures or overflows during these events. See “THE DISTRICT – Emergency Management: Response and Recovery.” Customers The historical number of customers served by the District for the Fiscal Years 2020-21 through Fiscal Year 2024-25 and the projected number of customers served by the District for the Fiscal Years 2025-26 through 2029-30, identified in equivalent dwelling units (“EDUs”), are set forth in Table 8 below.

Assessed Valuation The assessed valuation of property in the County is established by the County Assessor, except for public utility property which is assessed by the State Board of Equalization. Due to changes in assessment required under State Constitution Article XIIIA, the County assessment roll no longer purports to be proportional to market value. See “LIMITATIONS ON TAXES AND REVENUES” herein. Generally, property can be reappraised upward to market value only upon a change in ownership or completion of new construction. The assessed value of property that has not incurred a change of ownership or new construction must be adjusted annually to reflect inflation at a rate not to exceed 2% per year based on the State consumer price index. In the event of declining property value caused by substantial damage, destruction, economic or other factors, the assessed value must be reduced temporarily to reflect market value. For the definition of full cash value and more information on property tax limitations and adjustments, see “LIMITATIONS ON TAXES AND REVENUES” herein. The County Assessor determines and enrolls a value for each parcel of taxable real property in the County every year. The value review may result in a reduction in value. Taxpayers in the County also may appeal the determination of the County Assessor with respect to the assessed value of their property.

Tax Levies and Delinquencies Property taxes are based on assessed valuation which is determined as described under “DISTRICT REVENUES – Assessed Valuation” herein. In accordance with the California Revenue and Taxation Code, the County tax collector collects secured tax levies for each Fiscal Year. Property taxes on the secured roll are due in two installments, on November 1 and February 1. The District currently participates in the County’s Teeter Plan under which the District receives annually 100% of the secured property tax levies and Sewer Service Charges to which it otherwise is entitled, regardless of whether the County has actually collected the levies. This alternative method provides for funding each taxing entity included in the Teeter Plan with its total secured property taxes during the year the taxes are levied, including any amount uncollected at fiscal year-end. Under this plan, the District’s general fund receives the full amount of secured property taxes levied each year on its behalf and, for so long as such plan remains in effect, the participating entities, such as the District, no longer experience delinquent taxes. The County’s general fund is the designated recipient of future collections of penalties and interest on all delinquent taxes collected on behalf of participants in this alternative method of apportionment. The County Board adopted its Teeter Plan in 1993. Once adopted, a county’s Teeter Plan will remain in effect in perpetuity unless the Board of Supervisors orders its discontinuance or unless prior to the commencement of a fiscal year a petition for discontinuance is received and joined in by resolutions of the governing bodies of not less than two thirds of the participating districts in the county. An electing county may, however, opt to discontinue the Teeter Plan with respect to any levying agency in the county if the Board of Supervisors, by action taken not later than July 15 of a fiscal year, elects to discontinue the procedure with respect to such levying agency and the rate of secured tax delinquencies in that agency in any year exceeds 3% of the total of all taxes and assessments levied on the secured roll by that agency. If the Teeter Plan is discontinued subsequent to its implementation, only those secured property taxes actually collected would be allocated to political subdivisions (including the District) for which the County acts as the tax-levying or tax-collecting agency, but penalties and interest would be credited to the political subdivisions. The District is not aware of any petitions for the discontinuance of the Teeter Plan in the County or any proposal formally before the County Board to discontinue the Teeter Plan with respect to the District. 298610182.5 44 Set forth in Table 12 below is a five-year history of the District’s ad valorem total property tax and Sewer Service Charge levies.

Budgetary Process The District’s operating fund budget relies on revenues from Sewer Service Charges and property taxes, both of which are collected on the property tax bill, as previously described under the captions “— Sewer Service Charges” and “— Additional Revenues.” The District receives tax revenues from the County in eight allocations, with the largest receipts in December and April. The District operates on a Fiscal Year beginning each July 1. The operating fund budgets include funds to cover the dry period of each tax year, i.e., the period from the beginning of the Fiscal Year until the first taxes are received. The dry-period requirement is budgeted at one-half of the annual operating fund budgeted expenditures. The District uses the accrual method of accounting in its budgets. The District has conformed to its budgets for the last five fiscal years and is conforming to its budget for the current fiscal year. The District’s annual budget preparation process begins in January of each year and concludes in June upon its adoption. The General Manager reviews the final operating budgets and then distributes them to the Directors and District Committees for consideration. The Board of Directors then adopts the proposed annual budgets, with any revisions, in June of each year. Budgetary control is exercised at the individual Department level and administrative policies provide guidelines on budget transfers and the authorization necessary to implement transfers. A budget adjustment is a transfer which does not change the total appropriated amount and does not require Board of Directors action. Approval may be granted by the General Manager or the Department Head in certain circumstances. Department Heads have the discretion to reapportion funds between certain line items within a division but may not exceed total appropriated amounts for each department. They may also transfer staff across divisional lines. The General Manager and Board of Directors must approve additional capital outlay items. A budget amendment is an adjustment to the total appropriated amount which was not included in the original budget. These supplemental appropriations require formal action by the Board of Directors. Prior year reserves or fund balances may be appropriated to fund items not previously included in the adopted budget. Reserves or fund balances exceeding minimum amounts required by fiscal policies may be appropriated if it is determined to be in the best interest of the District. Directors may also appropriate reserves in case of emergencies or unusual circumstances. 298610182.5 45 Reserves The District has an established reserve policy with seven distinct reserve criteria which together comprise the District’s reserve fund target. Over a ten-fiscal year period, these requirements collectively result in a year-ending reserve total for each fiscal year projected not to fall below $564 million as indicated in the District’s ten-year cash flow forecast for Fiscal Years 2025-26 through 2034-35. Collectively, these requirements average $570 million a year over the current ten-year cash flow forecast to support the operation and maintenance of the District’s $15.7 billion in assets. The District’s reserves are not held in segregated accounts. They consist of the following components based on the described criteria:  Cash Flow Criterion has been established at a level to fund operations, maintenance and certificate of participation expenses for the first half of the fiscal year, prior to the receipt of the first installment of the property tax allocation and sewer service user fees which are collected as a separate line item on the property tax bill. The level of this criterion has been established as the sum of an amount equal to six months operations and maintenance expenses and the total of the annual debt or certificate of participation service payments due in August each year.  Operating Contingency Criterion has been established to provide for non-recurring expenditures that were not anticipated when the annual budget was considered and adopted. The level of this criterion has been established at an amount equal to ten percent of the current fiscal year’s annual operating budget.  Capital Improvement Criterion has been maintained to fund annual increments of the CIP. The target level of this criterion has been established at one half of the average annual cash outlay of the CIP through the year 2035. Levels higher and lower than the target can be expected while the long-term financing and capital improvement programs are being finalized.  Catastrophic Loss or Self-Insurance Criterion has been maintained for property damage including fire, flood, and earthquake, for general liability and for workers’ compensation. This reserve criterion is intended to work with purchased insurance policies, FEMA and State disaster reimbursements. Based on the plant infrastructure replacement value, the level of this criterion has been set to fund the District’s non-reimbursed costs, estimated to be $100 million.  Capital Replacement/Refurbishment Criterion has been established to provide funding to replace or refurbish the current collection, treatment and recycling facilities at the end of their useful economic lives. The current replacement value of these facilities is estimated to be approximately $15.7 billion. The reserve criterion level has been established at $75 million.  Debt Service Required Reserves Criterion has been established at ten percent of the outstanding certificate of participation issues. Other debt service reserves are required to be under the control of a Trustee by the provisions of the certificate of participation issues. These funds are not available for the general needs of the District and must be maintained at specified levels.  Accumulated Funds exceeding the targets specified by District policy will be maintained for Capital Improvement and for rate stabilization purposes. These funds will be applied to future years’ CIP needs due to the timing of the actual CIP outlays, in order to moderate annual fluctuations. There is currently no established target for this reserve. 298610182.5 46 Set forth in Table 13 below are the actual reserves at June 30, 2021, June 30, 2022, June 30, 2023, June 30, 2024 and June 30, 2025 for each fund.

Projections for Fiscal Years 2025-26 through 2029-30 are based on assumptions in the Fiscal Year 2025-26 Budget Update approved on June 25, 2025. They assume the number of projects and scheduled build out set forth in the 2023 CIP Validation Study. The projections also reflect the Board- approved annual rate increases of 3.5% for each of Fiscal Years 2025-26 through 2027-28 and 4.87% thereafter. Principal outlay components of these projections are derived from the 2025 CIP Validation Study, which identified 74 individual capital projects with projected outlay of $3.6 billion over the Fiscal Years 2025-26 through 2034-35. Much of the construction is scheduled during the next five years, with average annual capital outlays of $319.9 million. The District’s net CIP cash flow budget for Fiscal Year 2025-26 is $254.3 million, which factors in allocation for future rehabilitation and savings and deferrals. This CIP budget finances joint works treatment and disposal system improvement projects, and collection system improvement projects. The preparation of such projections was based upon certain assumptions and certain forecasts with respect to conditions that may occur in the future. While the District believes that these assumptions and forecasts are reasonable for the purposes of the projected selected operating data, it makes no representation that they will in fact occur. To the extent that actual future conditions differ from those assumed herein, the data will vary.

They also reflect (i) the Board-approved annual rate increase of 3.5% for Fiscal Years 2025-26 through 2027- 28 and 4.87% thereafter. c) Revenue Area No. 14 Fees are derived based on the projected contribution of sewage flows to the District from the Irvine Ranch Water District. d) Ad Valorem Taxes are projected with annual increases of 3% from Fiscal Years 2025-26 through 2029-30. The District budgets revenues from Ad Valorem Taxes at levels that are lower than the District’s expected levels. Any fluctuations in actual Ad Valorem Tax revenue received against projected Ad Valorem Tax revenue are due, in part, to recent home sales and other market factors. Although the District received $138.3 million from Ad Valorem Taxes in Fiscal Year 2024-25, the District’s budget for Fiscal Year 2024-25 reflects projected revenue at $117.6 million. e) Interest earnings are projected to average 3% of annual cash balances. f) Operating and Maintenance Expenses are forecasted with a base increase of 2.5% per year beginning with Fiscal Year 2026- 27 with adjustments for known periodic outlays that do not occur annually. g) Annual CIP Outlays are based on the cash flow projections developed from the 2025 CIP Validation Study, with adjustments for CIP savings and deferrals.

It serves 2.6 million people in central and northwest portion of the County, and the District’s mission statement is “[t]o protect public health and the environment by providing effective wastewater collection, treatment, and recycling.” The objectives of operating the reclamation plants are to process and pass on for purification or dispose of the treated wastewater and the separated solids in accordance with federal, state and local laws including the EPA. Preparing and planning is essential for the future of the District and the community it serves. As part of the planning process, the District has adopted the Strategic Plan. Strategic planning is the first step in defining the District’s ability to have people and assets in the right place at the right time to meet its agreed upon mission and levels of service. The Strategic Plan defines the strategic initiatives to be pursued by the District and provides a basis for long-term financial, capital and operational planning. Key policies are focused on four broad categories (Business Principles, Environmental Stewardship, Wastewater Management, and Workplace Environment) and fifteen policy areas. The District’s Master Plan drives the District’s 20-year CIP and determines the proper timing of projects to maximize the life of assets. The Asset Management team works continuously with the Operations and Maintenance Department to properly define the timing of large CIP projects and the execution of many small projects essential to the day-to-day operations of the collections and plants to maintain reliable and resilient facilities. As of June 30, 2024, the District has a financial net position of $3.2 billion, which is an increase of $197.8 million, or 6.6%, over the prior year net position. Of this amount, $872.2 million represents unrestricted net position, which may be used to meet the District’s ongoing obligations to citizens and creditors. Net capital assets, consisting of non-depreciable capital assets and depreciable capital assets net of accumulated depreciation, increased $137.5 million, or 4.8% over the prior year. Net investment in capital assets increased $316.0 million, or 16.2% over the prior year. Total outstanding debt decreased by $183.6 million, or 23.3% from the prior year to $606.1 million. The District considers various factors in preparing the biennium budget, including the County’s unemployment rate, inflation and the yield on its investments. The District’s user fee schedule was increased by 3.2% for fiscal year 2023-24, which is necessary to support the District’s cash flow needs for operating costs, debt service and capital improvement outlays. As a result, operating revenues increased by $6.9 million, or 2.1%, over the prior year due to the increased user fee. Non-operating revenues increased $56.0 million, or 35.4 %, from prior year primarily from growth in investment and interest income, higher property tax revenues, contributions from other governments equity share integration adjustments and insurance recoveries. Operating expenses (other than depreciation and amortization) increased $15.5 million, or 7.5%, from prior year primarily due to increases in supplies, repairs and maintenance due to digester cleaning, repairs, chemical costs, contractual services, and other operating services. Non-operating expenses increased $7.6 million, or 27.2%, from prior year. Capital contributions decreased $14.0 million, or 43.5%, from the prior year, due to a decrease in capital facility capacity charges fees collected from cities and supplemental capital facilities capacity charges assessed to industrial dischargers, and decrease in capital contributions from other governments. Reflective of reimbursements from Orange County Water District for groundwater replenishment system costs. 298610182.5 51 Investment of District Funds State statutes authorize the District to invest in obligations of the United States Government, state and local governmental agencies, negotiable certificates of deposits, banker’s acceptances, commercial paper, reverse repurchase agreements and a variety of other investment instruments which are allowable under California Government Code Section 53600 et seq. All District funds, except for Obligation Reserve Funds controlled by a bank trustee pursuant to the provisions of Existing Senior Obligations, are managed by an external money manager, Insight Investment. U.S. Bank Trust Company, National Association serves as the District’s independent custodian bank for its investment program. Callan LLC serves as the District’s independent advisor. As of June 30, 2025, the District’s externally managed fund consisted of a short-term investment portfolio of $192.9 million with an average maturity of 51 days, and a long-term investment portfolio of $640.9 million with average maturities of 3.3 years. Investments consist of United States government securities, corporate bonds and commercial paper. The District’s portfolio contains no structured investment vehicles (“SIVs”) or reverse repurchase agreements. Deposits in banks are maintained in financial institutions which provide deposit protection on the bank balance from the Federal Deposit Insurance Corporation. The California Government Code requires State banks and savings and loans to secure local government deposits by pledging government securities equal to 110% of the deposits or by pledging first trust deed mortgage notes equal to 150% of the deposits. The District’s Investment Policy requires that the District invest public funds in a manner which ensures the safety and preservation of capital while meeting reasonable anticipated operating expenditure needs, achieving a reasonable rate of return and conforming to all State and local statutes governing the investment of public funds. The primary objectives, in order, of the District’s investment activities are safety, liquidity and return on investment. FINANCIAL OBLIGATIONS Existing Indebtedness Currently, the District has Senior Obligations Outstanding payable on parity with the Revenue Obligations. The table on the next page describes the District’s outstanding parity certificates of participation as of June 30, 2025. The payment obligations in connection with each series of these certificates of participation constitute Senior Obligations, subject to the provisions of the Master Agreement and shall be afforded all of the benefits, interests and security afforded Senior Obligations pursuant to the Master Agreement. The District has no general obligation bonds or subordinate bonds outstanding.

In connection with the execution and delivery of the above-referenced outstanding certificates of participation, the District entered into certain installment purchase agreements, or equivalent documents, providing for the payment of installment payments or similar payments. Anticipated Financings From time to time the District may incur other obligations to finance portions of the CIP and to refund the Revenue Obligations. Over the next five years, however, the District does not expect to issue any additional debt, other than refunding debt. The District expects to refund outstanding obligations from time to time. See “SECURITY AND SOURCES OF PAYMENT FOR THE REVENUE OBLIGATIONS – Sale Proceeds of Future Obligations.” THE CORPORATION The Corporation was organized on June 19, 2000 as a nonprofit public benefit corporation pursuant to the Nonprofit Public Corporation law of the State. The Corporation’s purpose is to render assistance to the District in its acquisition of equipment, real property and improvements on behalf of the District. Under its articles of incorporation, the Corporation has all powers conferred upon nonprofit public benefit corporations by the laws of the State, provided that it will not engage in any activity other than that which is necessary or convenient for, or incidental to the purposes for which it was formed. The Corporation is a separate legal entity from the District. It is governed by a twenty-five member Board of Directors. The Corporation has no employees. All staff work is performed by employees of the District. The members of the Corporation’s Board of Directors are the Board of Directors of the District. The District’s Assistant General Manager, Director of Finance and other District employees are available to provide staff support to the Corporation. The Corporation has not entered into any material financing arrangements other than those referred to in this Official Statement. Further information concerning the Corporation may be obtained from the Orange County Sanitation District office at 18480 Bandilier Circle, Fountain Valley, California, 92708. 298610182.5 53 LIMITATIONS ON TAXES AND REVENUES Article XIIIA of the California Constitution On June 6, 1978, California voters approved Proposition 13 (“Proposition 13”), which added Article XIIIA to the State Constitution (“Article XIIIA”). Article XIIIA, as amended, limits the amount of any ad valorem tax on real property to one percent of the full cash value thereof, except that additional ad valorem taxes may be levied to pay debt service on (i) indebtedness approved by the voters prior to July 1, 1978, (ii) (as a result of an amendment to Article XIIIA approved by State voters on June 3, 1986) on bonded indebtedness for the acquisition or improvement of real property which has been approved on or after July 1, 1978 by two-third of the voters on such indebtedness, and (iii) bonded indebtedness incurred by a school district or community college district for the construction, reconstruction, rehabilitation or replacement of school facilities or the acquisition or lease of real property for school facilities, approved by 55% of the voters of the district, but only if certain accountability measures are included in the proposition. Article XIIIA defines full cash value to mean “the county assessor’s valuation of real property as shown on the 1975-76 tax bill under “full cash value,” or thereafter, the appraised value of real property when purchased, newly constructed, or a change in ownership has occurred after the 1975 assessment.” The full cash value may be adjusted annually to reflect inflation at a rate not to exceed 2% per year or to reflect a reduction in the consumer price index or comparable data for the area under the taxing jurisdiction, or reduced in the event of declining property values caused by substantial damage, destruction, or other factors. Amendments to the California Constitution have implemented and modified limits on reassessment of property value upon transfers. Most recently, Proposition 19 limits people who inherit family properties from keeping a low property tax base resulting from the 2% restriction on increases, unless they use the home as their primary residence. It also allows homeowners who are over 55 years of age, disabled, or victims of a wildfire or natural disaster to transfer their assessed value of their primary home to a newly purchased or newly constructed replacement primary residence up to three times. Legislation enacted by the State Legislature to implement Article XIIIA provides that notwithstanding any other law, local agencies may not levy any ad valorem property tax except to pay debt service on indebtedness approved by the voters as described above. Legislation Implementing Article XIIIA Legislation has been enacted and amended a number of times since 1978 to implement Article XIIIA. Under current law, local agencies are no longer permitted to levy directly any property tax (except to pay voter-approved indebtedness). The one percent property tax is automatically levied by the County and distributed according to a formula among taxing agencies. The formula apportions the tax roughly in proportion to the relative shares of taxes levied prior to 1979. Increases of assessed valuation resulting from reappraisals of property due to new construction, change in ownership or from the 2% annual adjustment are allocated among the various jurisdictions in the “taxing area” based upon their respective “situs.” Any such allocation made to a local agency continues as part of its allocation in future years. Beginning in the 1981-82 fiscal year, assessors in the State no longer record property values on tax rolls at the assessed value of 25% of market value which was expressed as $4 per $100 assessed value. All taxable property is now shown at full market value on the tax rolls. Consequently, the tax rate is expressed as $1 per $100 of taxable value. All taxable property value included in this Official Statement is shown at 100% of market value (unless noted differently) and all tax rates reflect the $1 per $100 of taxable value. 298610182.5 54 Article XIIIB of the California Constitution An initiative to amend the State Constitution entitled “Limitation of Government Appropriations” was approved on September 6, 1979, thereby adding Article XIIIB to the State Constitution (“Article XIIIB”). Under Article XIIIB, the State and each local governmental entity has an annual “appropriations limit” and is not permitted to spend certain moneys that are called “appropriations subject to limitation” (consisting of tax revenues, state subventions and certain other funds) in an amount higher than the appropriations limit. Article XIIIB does not affect the appropriations of moneys that are excluded from the definition of “appropriations subject to limitation,” including debt service on indebtedness existing or authorized as of January 1, 1979, or bonded indebtedness subsequently approved by the voters. In general terms, the appropriations limit is to be based on certain 1978-79 expenditures, and is to be adjusted annually to reflect changes in consumer prices, populations, and services provided by these entities. Among other provisions of Article XIIIB, if these entities’ revenues in any year exceed the amounts permitted to be spent, the excess would have to be returned by revising tax rates or fee schedules over the subsequent two years. “Appropriations subject to limitation” are authorizations to spend “proceeds of taxes,” which consist of tax revenues, state subventions and certain other funds, including proceeds from regulatory licenses, user charges or other fees to the extent that such proceeds exceed “the cost reasonably borne by such entity in providing the regulation, product or service,” but “proceeds of taxes” excludes tax refunds and some benefit payments such as unemployment insurance. No limit is imposed on appropriations of funds which are not “proceeds of taxes,” such as reasonable user charges or fees, and certain other non-tax funds. Not included in the Article XIIIB limit are appropriations for the debt service costs of bonds existing or authorized by January 1, 1979, or subsequently authorized by the voters, appropriations required to comply with mandates of courts or the federal government and appropriations for qualified capital outlay projects. The appropriations limit may also be exceeded in certain cases of emergency. The appropriations limit for the District in each year is based on the District’s limit for the prior year, adjusted annually for changes in the cost of living and changes in population, and adjusted, where applicable, for transfer of financial responsibility of providing services to or from another unit of government. The change in the cost of living is, at the District’s option, either (1) the percentage change in State per capita personal income, or (2) the percentage change in the local assessment roll on nonresidential property. Either test is likely to be greater than the change in the cost of living index, which was used prior to Proposition 111. Change in population is to be measured either within the jurisdiction of the District or the County as a whole. As amended by Proposition 111, the appropriations limit is tested over consecutive two-year periods. Any excess of the aggregate “proceeds of taxes” received by a District over such two-year period above the combined appropriations limits for those two years is to be returned to taxpayers by reductions in tax rates or fee schedules over the subsequent two years. As originally enacted in 1979, the District’s appropriations limit was based on 1978-79 authorizations to expend proceeds of taxes and was adjusted annually to reflect changes in cost of living and population (using different definitions, which were modified by Proposition 111). Starting with Fiscal Year 1990-91, the District’s appropriations limit was recalculated by taking the actual Fiscal Year 1986-87 limit, and applying the annual adjustments as if Proposition 111 had been in effect. The District does not anticipate that any such appropriations limitations will impair its ability to make Installment Payments as required by the Installment Purchase Agreement. 298610182.5 55 Proposition 1A and Proposition 22 Proposition 1A (“Proposition 1A”), proposed by the Legislature in connection with the 2004-05 Budget Act and approved by the voters in November 2004, restricts State authority to reduce major local tax revenues such as the tax shifts permitted to take place in Fiscal Years 2004-05 and 2005-06. Proposition 1A provides that the State may not reduce any local sales tax rate, limit existing local government authority to levy a sales tax rate or change the allocation of local sales tax revenues, subject to certain exceptions. Proposition 1A generally prohibits the State from shifting to schools or community colleges any share of property tax revenues allocated to local governments for any fiscal year, as set forth under the laws in effect as of November 3, 2004. Any change in the allocation of property tax revenues among local governments within a county must be approved by two-thirds of both houses of the Legislature. Proposition 1A provides, however, that beginning in Fiscal Year 2008-09, the State may shift to schools and community colleges up to 8% of local government property tax revenues, which amount must be repaid, with interest, within three years, if the Governor proclaims that the shift is needed due to a severe state financial hardship, the shift is approved by two-thirds of both houses and certain other conditions are met. Such a shift may not occur more than twice in any ten-year period. The State may also approve voluntary exchanges of local sales tax and property tax revenues among local governments within a county. Proposition 1A was generally superseded by the passage of a new initiative constitutional amendment at the November 2010 election, known as Proposition 22 (“Proposition 22”). The effect of Proposition 22 is to prohibit the State, even during a period of severe fiscal hardship, from delaying the distribution of tax revenues for transportation, redevelopment, or local government projects and services. It prevents the State from redirecting redevelopment agency property tax increment to any other local government or from temporarily shifting property taxes from cities, counties and special districts to schools. This is intended to, among other things, stabilize local government revenue sources by restricting the State’s control over local property taxes. Prior to the passage of Proposition 22, the State invoked Proposition 1A to divert $1.935 billion in local property tax revenues in fiscal year 2009-10 from cities, counties, and special districts to the State to offset State general fund spending for education and other programs. Approximately $5 million of the District’s property tax revenues were diverted to the State as a result of this Proposition 1A suspension. The District participated in a Proposition 1A Securitization Program (the “Program”) sponsored by the California Statewide Communities Development Authority. The Program allowed the District to exchange its anticipated State property tax receivable for an equal amount of cash. In addition, the State’s adopted 2009-10 budget included a $1.7 billion diversion in local property tax revenues from local redevelopment agencies. Many California Redevelopment Association members are actively engaged in litigation to block such diversion and recoup certain payments already made under certain legislation passed in July 2009 that is beyond the reach of Proposition 22, known as “ABX4 26.” Proposition 1A also provides that if the State reduces the vehicle license fee (“VLF”) rate currently in effect, 0.65% of vehicle value, the State must provide local governments with equal replacement revenues. Further, Proposition 1A requires the State to suspend State mandates affecting cities, counties and special districts, excepting mandates relating to employee rights, schools or community colleges, in any year that the State does not fully reimburse local governments for their costs to comply with such mandates. Article XIIIC and Article XIIID of the California Constitution Proposition 218, a State ballot initiative known as the “Right to Vote on Taxes Act,” was approved by the voters on November 5, 1996. The initiative added Articles XIIIC and XIIID to the California 298610182.5 56 Constitution, creating additional requirements for the imposition by most local governments of “general taxes,” “special taxes,” “assessments,” “fees,” and “charges.” Proposition 218 became effective, pursuant to its terms, as of November 6, 1996, although compliance with some of its provisions was deferred until July 1, 1997, and certain of its provisions purport to apply to any tax imposed for general governmental purposes (i.e., “general taxes”) imposed, extended or increased on or after January 1, 1995 and prior to November 6, 1996. Article XIIID imposes substantive and procedural requirements on the imposition, extension or increase of any “fee” or “charge” subject to its provisions. A “fee” or “charge” subject to Article XIIID includes any levy, other than an ad valorem tax, special tax or assessment, imposed by an agency upon a parcel or upon a person as an incident of property ownership. Article XIIID prohibits, among other things, the imposition of any proposed fee or charge, and, possibly, the increase of any existing fee or charge, in the event written protests against the proposed fee or charge are presented at a required public hearing on the fee or charge by a majority of owners of the parcels upon which the fee or charge is to be imposed. Except for fees and charges for water, sewer and refuse collection services, the approval of a majority of the property owners subject to the fee or charge, or at the option of the agency, by a two-thirds vote of the electorate residing in the affected area, is required within 45 days following the public hearing on any such proposed new or increased fee or charge. The California Supreme Court decisions in Richmond v. Shasta Community Services District, 32 Cal.4th 409 (2004) (“Richmond”), and Bighorn-Desert View Water Agency v. Verjil, 39 Cal.4th 205 (2006) (“Bighorn”) have clarified some of the uncertainty surrounding the applicability of Section 6 of Article XIIID to service fees and charges. In Richmond, the Shasta Community Services District charged a water connection fee, which included a capacity charge for capital improvements to the water system and a fire suppression charge. The Court held that both the capacity charge and the fire suppression charge were not subject to Article XIIID because a water connection fee is not a property-related fee or charge because it results from the property owner’s voluntary decision to apply for the connection. In both Richmond and Bighorn, however, the Court stated that a fee for ongoing water service through an existing connection is imposed “as an incident of property ownership” within the meaning of Article XIIID, rejecting, in Bighorn, the water agency’s argument that consumption-based water charges are not imposed “as an incident of property ownership” but as a result of the voluntary decisions of customers as to how much water to use. Article XIIID also provides that “standby charges” are considered “assessments” and must follow the procedures required for “assessments” under Article XIIID and imposes several procedural requirements for the imposition of any assessment, which may include (1) various notice requirements, including the requirement to mail a ballot to owners of the affected property; (2) the substitution of a property owner ballot procedure for the traditional written protest procedure, and providing that “majority protest” exists when ballots (weighted according to proportional financial obligation) submitted in opposition exceed ballots in favor of the assessments; and (3) the requirement that the levying entity “separate the general benefits from the special benefits conferred on a parcel” of land. Article XIIID also precludes standby charges for services that are not immediately available to the parcel being charged. Article XIIID provides that all existing, new or increased assessments are to comply with its provisions beginning July 1, 1997. Existing assessments imposed on or before November 5, 1996, and “imposed exclusively to finance the capital costs or maintenance and operations expenses for [among other things] water” are exempted from some of the provisions of Article XIIID applicable to assessments. Article XIIIC extends the people’s initiative power to reduce or repeal existing local taxes, assessments, fees and charges. This extension of the initiative power is not limited by the terms of Article XIIIC to fees, taxes, assessment fees and charges imposed after November 6, 1996 and absent other authority could result in retroactive reduction in any existing taxes, assessments, fees or charges. In Bighorn, the Court concluded that under Article XIIIC local voters by initiative may reduce a public 298610182.5 57 agency’s water rates and delivery charges. The Court noted, however, that it was not holding that the authorized initiative power is free of all limitations, stating that it was not determining whether the electorate’s initiative power is subject to the public agency’s statutory obligation to set water service charges at a level that will “pay the operating expenses of the agency, . . . provide for repairs and depreciation of works, provide a reasonable surplus for improvements, extensions, and enlargements, pay the interest on any bonded debt, and provide a sinking or other fund for the payment of the principal of such debt as it may become due.” Under Ordinance No. OC SAN-58 adopted on March 22, 2023, the District established residential Sewer Service Charges, except within Revenue Area No. 14 (for which service is billed directly to the IRWD), based on the cost of services and facilities provided to each customer of the District. The noticed public hearing held in connection with the adoption of this ordinance considered an increase in the single family residential rate, the underlying rate for all of the District’s sewer service charges, of 3.5% for Fiscal Year 2023-24 through Fiscal Year 2027-28. These increases were approved by the Board through the adoption of Ordinance No. OC SAN-58. Pursuant to the Master Agreement, the District will, to the extent permitted by law, fix, prescribe and collect fees and charges for the services of the Wastewater System which will be at least sufficient to yield during each Fiscal Year (a) Net Revenues equal to 125% of Debt Service on Senior Obligations for such Fiscal Year, and (b) Net Operating Revenues equal to 100% of Debt Service on all Obligations for such Fiscal Year. The District may make adjustments from time to time in such fees and charges and may make such classification thereof as it deems necessary, but will not reduce the fees and charges then in effect unless the Revenues and Net Revenues from such reduced fees and charges will at all times be sufficient to meet the requirements of the Master Agreement. If service charges are determined to be subject to Article XIIID, and proposed increased service charges cannot be imposed as a result of a majority protest, such circumstances may adversely affect the ability of the District to generate revenues in the amounts required by the Master Agreement, and to make Installment Payments as provided in the Installment Purchase Agreement. No assurance may be given that Articles XIIIC and XIIID will not have a material adverse impact on Net Revenues. Other Initiative Measures Articles XIIIA, XIIIB, XIIIC and XIIID were adopted pursuant to California’s constitutional initiative process. From time to time other initiative measures could be adopted by California voters, placing additional limitations on the ability of the District to increase revenues. RISK FACTORS This section describes certain special considerations and risk factors affecting the payment of and security for the Revenue Obligations. The following discussion is not meant to be an exhaustive list of the risks associated with the purchase of any Revenue Obligations and the order does not necessarily reflect the relative importance of the various risks. Potential investors in the Revenue Obligations are advised to consider these special factors along with all other information in this Official Statement in evaluating the Revenue Obligations. There can be no assurance that other considerations will not materialize in the future, and if additional considerations materialize to a sufficient degree, they could delay or prevent payment of principal and interest evidenced by the Revenue Obligations. Limited Obligations The Revenue Obligations are certificates of participation that evidence direct, fractional undivided interests of the Owners thereof in the Installment Payments. The obligation of the District to pay the 298610182.5 58 Installment Payments and the interest thereon and other payments required to be made by it under the Installment Purchase Agreement is a special obligation of the District payable, in the manner provided under the Installment Purchase Agreement, solely from Net Revenues, and other funds as provided in the Installment Purchase Agreement. The obligation of the District to pay the Installment Payments and the interest thereon is a limited obligation of the District and is not secured by a legal or equitable pledge or charge or lien upon any property of the District or any of its income or receipts, except the Net Revenues. Factors that can adversely affect the availability of Net Revenues include, among other matters, general and local economic conditions, and changes in law and government regulations (including initiatives and moratoriums). The realization of future Net Revenues is also subject to, among other things, the capabilities of management of the District, the ability of the District to provide wastewater service to its customers, the ability of the District to establish, maintain and collect charges for the wastewater service to its customers and the ability of the District to establish, maintain and collect rates and charges sufficient to pay the Installment Payments and the interest thereon . Wastewater System Maintenance and Operation Costs and Net Revenues There can be no assurance that the District’s Maintenance and Operation Costs for the Wastewater System will remain at the levels described in this Official Statement. Changes in technology, energy or other expenses, including any increased treatment costs, due to inflation or otherwise, could reduce the District’s Net Revenues and require substantial increases in rates or charges. Such rate increases could increase the likelihood of nonpayment or decrease demand. Although the District has covenanted to prescribe, revise and collect rates and charges for the Wastewater System at certain levels, there can be no assurance that such amounts will be collected in the amounts and at the times necessary to make timely payments with respect to the Revenue Obligations. Construction projects in the capital program are subject to ordinary construction risks and delays applicable to projects of their kind, including but not limited to (i) inclement weather affecting contractor performance and timeliness of completion, which could affect the costs and availability of, or delivery schedule for, equipment, components, materials, labor or subcontractors; (ii) contractor claims or nonperformance; (iii) failure of contractors to execute within contract price; (iv) work stoppages or slowdowns; (v) failure of contractors to meet schedule terms; (vi) supply chain issues; (vii) inflation; or (viii) unanticipated project site conditions, including the discovery of hazardous materials on the site or other issues regarding compliance with applicable environmental standards, and other natural hazards or seismic events encountered during construction. In addition, given the limited redundancy of certain wastewater facilities and systems, such systems must remain operational during construction, which could affect construction schedules or budgets. The ability of the District to comply with its covenants under the Master, Agreement and the Installment Purchase Agreement and generate Net Revenues sufficient to pay Installment Payments may be adversely affected by actions and events outside the control of the District and may be adversely affected by actions taken (or not taken) by voters, property owners, taxpayers or payers of assessments, fees and charges. See “LIMITATIONS ON TAXES AND REVENUES – Articles XIIIC and XIIID of the California Constitution.” The remedies available to the owners of the Revenue Obligations upon the occurrence of an event of default under the Installment Purchase Agreement are in many respects dependent upon judicial actions that are typically subject to discretion and delay and could prove both expensive and time consuming to obtain. 298610182.5 59 Environmental Laws and Regulations Wastewater collection, treatment and disposal facilities are subject to a wide variety of local, State, and federal health and environmental laws. Among the types of regulatory requirements faced by such facilities are air and water quality control requirements and biosolids regulations. Such regulations, as they may be from time to time amended or subsequently enacted could affect the Net Revenues available to pay the Installment Payments. See “THE DISTRICT – Permits, Licenses and Other Regulations” and “ – Biosolids Management.” Natural Disasters A number of natural disasters could affect the physical condition of the Wastewater System facilities and/or the ability or willingness of Wastewater System customers to pay their sewer bills when due. This may include the following: Climate Change and Weather. The change in the earth’s average atmospheric temperature, generally referred to as “climate change,” is expected to, among other things, increase the frequency and severity of extreme weather events and cause rising sea levels and substantial flooding. The impacts of climate change may materially adversely affect the finances and operations of the Wastewater System. The sewers and pumping plants can be threatened by increased flooding risks, sinkholes, decreased flows, power outages, service disruptions, and other changes in subsurface conditions that are caused by the fluctuating climate extremes between wet and dry weather events. The District’s Climate Resiliency Study, which was completed in November 2019, provides a comprehensive analysis of climate-related, site-specific risk assessments of the District’s facilities using available climate predictions, industry standards, and geographical information systems. The analysis from the study is used to further develop strategies for climate risk and resiliency. See “THE DISTRICT – Climate Issues.” Seismic. The District, like most communities in California, is an area of unpredictable seismic activity, and therefore, is subject to potentially destructive earthquakes. Southern California is characterized by a number of geotechnical conditions that represent potential safety hazards, including expansive soils and areas of potential liquefaction and landslide. The CIP includes planned improvements to facilities for the purpose of improving seismic reliability. See “THE DISTRICT – Capital Improvement Plan.” The District has limited earthquake insurance partially covering several key structures; beyond that, the District relies on a combination of self-insurance and District reserves for all property damage from the perils of seismic activity. See “THE DISTRICT – Risk Management.” Although the District continues to improve seismic reliability, there can be no assurance that these or any additional measures will be adequate in the event that a natural disaster occurs, nor that costs of preparedness measures will be as currently anticipated. Further, damage to components of the Wastewater System could cause a material increase in costs for repairs or a corresponding material adverse impact on Net Revenues. Sewer Failure. The Wastewater System is subject to potential failures of its sewage collection and conveyance systems due the potential impact of climate change or natural disasters that can result in unexpected repair costs and other expenses. Although the District has implemented disaster preparedness plans and made improvements to Wastewater System facilities in connection with such potential disasters, there can be no assurance that these or any additional measures will be adequate in the event that a disaster occurs, nor that costs of preparedness measures will be as currently anticipated. Further, damage to components of the Wastewater System could cause a material increase in costs for repairs or a corresponding material adverse impact on Net Revenues. See “THE DISTRICT –Emergency Management: Response and Recovery.” 298610182.5 60 The District is unable to predict the potential impact of heavy rains, flooding, sea level rise, earthquakes, tsunamis, extreme heat, wildfires and other natural disasters on the Wastewater System’s operations or financial condition. Cybersecurity The District, like many other public and private entities, relies on computer and other digital networks and systems to conduct its operations. As a recipient and provider of personal, private or other sensitive electronic information, the District is potentially subject to multiple cyber threats, including without limitation hacking, viruses, ransomware, malware and other attacks. No assurance can be given that its efforts to manage cyber threats and attacks will be successful in all cases, or that any such attack would not materially impact the operations or finances of any entity, including with respect to the administration of the Revenue Obligations. The District is also reliant on other entities and service providers in connection with its information technology generally, as well as with the administration of the Revenue Obligations, including without limitation the Trustee. Cybersecurity, and generally, protecting the District’s computer assets, networks, programs, data, and industrial control equipment from unauthorized access or attacks, is a listed topic of the District’s Strategic Plan. See “THE DISTRICT – Strategic Plan.” However, no assurance can be given that the District and these other entities will not be affected by cyber threats and attacks in a manner that may affect the owners of the Revenue Obligations. The District currently maintains commercial cyber liability coverage, but the District is not obligated to continue such coverage. See “THE DISTRICT – Risk Management.” Limitations on Remedies; Bankruptcy The District is authorized to file for bankruptcy protection pursuant to Chapter 9 of the United States Bankruptcy Code (the “Bankruptcy Code”) under certain circumstances. Should the District file for bankruptcy, there could be adverse effects on the owners of the Revenue Obligations. If the District is in bankruptcy, then the District’s creditors (including the Trustee on behalf of owners of the Revenue Obligations) may be prohibited from taking any action to collect any amount from the District or to enforce any obligation of the District without the bankruptcy court’s permission. This prohibition may also prevent the Trustee from making payments to the owners of the Revenue Obligations from funds in the Trustee’s possession. The rate covenant (see “SECURITY AND SOURCES OF PAYMENT FOR THE REVENUE OBLIGATIONS – Rate Covenant”) may not be enforceable in bankruptcy by the Trustee or the owners of the Revenue Obligations. The District may be able, without the consent and over the objection of the Trustee and the owners of the Revenue Obligations, to alter the priority, interest rate, principal amount, payment terms, collateral, maturity dates, payment sources, covenants (including tax-related covenants), and other terms or provisions of the Master Agreement, the Installment Purchase Agreement, the Trust Agreement and the Revenue Obligations as long as the bankruptcy court determines that the alterations are fair and equitable. There may be delays in Installment Payments, and consequently payments on the Revenue Obligations, while the District is in bankruptcy. There may be other possible effects of a bankruptcy of the District that could result in delays or reductions in payments on the Revenue Obligations, or result in losses to the owners of the Revenue Obligations. Regardless of any specific adverse determinations in a District bankruptcy proceeding, the fact of a District bankruptcy proceeding could have an adverse effect on the liquidity and value of the Revenue Obligations. 298610182.5 61 Rate Setting Process Under Proposition 218 Proposition 218, which added Articles XIIIC and XIIID to the State Constitution, affects the District’s ability to maintain existing rates and impose rate increases, and no assurance can be given that future rate increases will not encounter majority protest opposition or be challenged by initiative action authorized under Proposition 218. In the event that future proposed rate increases cannot be imposed as a result of majority protest or initiative, the District might thereafter be unable to generate Net Revenues in the amounts required by the Trust Agreement to pay the Revenue Obligations. The District believes that its current Wastewater System rates approved by the Board were effected in compliance with the notice, public hearing and majority protest provisions of Proposition 218. See “DISTRICT REVENUES – Sewer Service Charges” and “LIMITATIONS ON TAXES AND REVENUES – Articles XIIIC and XIIID of the California Constitution.” Loss of Tax-Exemption As highlighted under the heading “TAX MATTERS,” interest on the Revenue Obligations could become includable in gross income for purposes of federal income taxation retroactive to the date the Revenue Obligations were issued, as a result of future legislation (including legislation which may be currently proposed) or acts or omissions of the District in violation of its covenants in the Installment Purchase Agreement and the Trust Agreement. Should such an event of taxability occur, the Revenue Obligations are not subject to special redemption and will remain Outstanding until maturity or until redeemed under other provisions set forth in the Trust Agreement. LEGAL MATTERS The validity of the Revenue Obligations and certain other legal matters are subject to the approving opinion of Norton Rose Fulbright US LLP, Los Angeles, California, Special Counsel to the District. A complete copy of the proposed form of Special Counsel opinion is attached as Appendix F hereto. Special Counsel, in its capacity as Special Counsel to the District, undertakes no responsibility for the accuracy, completeness or fairness of this Official Statement. Certain legal matters will be passed on for the District and the Corporation by Best Best & Krieger LLP, Irvine, California, and for the District by Norton Rose Fulbright US LLP, Disclosure Counsel to the District. MUNICIPAL ADVISOR The District has retained PFM Financial Advisors LLC as an independent registered municipal advisor (the “Municipal Advisor”) in connection with the execution and delivery of the Revenue Obligations. The Municipal Advisor has not been engaged, nor have they undertaken, to audit, authenticate or otherwise verify the information set forth in the Official Statement, or any other related information available to the District, with respect to accuracy and completeness of disclosure of such information.

TAX MATTERS Federal Tax Exemption In the opinion of Norton Rose Fulbright US LLP, San Francisco, California, Special Counsel to the District, under existing statutes, regulations, rulings and judicial decisions, and assuming compliance by the District with certain covenants in the Trust Agreement, the Tax Certificate and other documents pertaining to the Revenue Obligations and requirements of the Internal Revenue Code of 1986 (the “Code”) regarding the use, expenditure and investment of proceeds of the Revenue Obligations and the timely payment of certain investment earnings to the United States, the portion of each Installment Payment representing interest and distributable in respect of any Revenue Obligation is not included in the gross income of the owners of the Revenue Obligations for federal income tax purposes. Failure to comply with such covenants and requirements may cause the portion of each Installment Payment representing interest and distributable in respect of any Revenue Obligation to be included in gross income retroactive to the date of execution and delivery of the Revenue Obligations. In the further opinion of Special Counsel, the portion of each Installment Payment representing interest and distributable in respect of any Revenue Obligation is not treated as an item of tax preference for purposes of the federal alternative minimum tax on individuals. Special Counsel expresses no opinion regarding the applicability of the federal corporate alternative minimum tax to the adjusted financial statement income of certain corporations. 298610182.5 63 Ownership of, or the receipt of interest on, tax-exempt obligations may result in collateral federal income tax consequences to certain taxpayers, including, without limitation, financial institutions, property and casualty insurance companies, certain foreign corporations doing business in the United States, certain S corporations with excess passive income, individual recipients of Social Security or Railroad Retirement benefits, taxpayers that may be deemed to have incurred or continued indebtedness to purchase or carry tax-exempt obligations and taxpayers who may be eligible for the earned income tax credit. Special Counsel expresses no opinion with respect to any collateral tax consequences and, accordingly, prospective purchasers of the Revenue Obligations should consult their own tax advisors as to the applicability of any collateral tax consequences. Certain requirements and procedures contained or referred to in the Trust Agreement, the Tax Certificate or other documents pertaining to the Revenue Obligations may be changed, and certain actions may be taken or not taken, under the circumstances and subject to the terms and conditions set forth in such documents, upon the advice or with the approving opinion of counsel nationally recognized in the area of tax-exempt obligations. Special Counsel expresses no opinion as to the effect of any change to any document pertaining to the Revenue Obligations or of any action taken or not taken where such change is made or action is taken or not taken without the approval of Norton Rose Fulbright US LLP or in reliance upon the advice of counsel other than Norton Rose Fulbright US LLP with respect to the exclusion from gross income of the portion of each Installment Payment representing interest and distributable in respect of any Revenue Obligation for federal income tax purposes. Special Counsel’s opinion is not a guarantee of result, but represents its legal judgment based upon its review of existing statutes, regulations, published rulings and judicial decisions and the representations and covenants of the District described above. No ruling has been sought from the Internal Revenue Service (the “IRS”) with respect to the matters addressed in the opinion of Special Counsel, and Special Counsel’s opinion is not binding on the IRS. The IRS has an ongoing program of examining the tax-exempt status of the interest on municipal obligations. If an examination of the Revenue Obligations is commenced, under current procedures the IRS is likely to treat the District as the “taxpayer,” and the owners of the Revenue Obligations would have no right to participate in the examination process. In responding to or defending an examination of the tax-exempt status of the portion of each Installment Payment representing interest and distributable in respect of any Revenue Obligation, the District may have different or conflicting interests from the owners. Additionally, public awareness of any future examination of the Revenue Obligations could adversely affect the value and liquidity of the Revenue Obligations during the pendency of the examination, regardless of its ultimate outcome. Tax Accounting Treatment of Bond Premium To the extent a purchaser acquires a Revenue Obligation at a price in excess of the amount payable at its maturity, such excess will constitute “bond premium” under the Code. The Code and applicable Treasury Regulations provide generally that bond premium on a tax-exempt obligation is amortized over the remaining term of the obligation (or a shorter period in the case of certain callable obligations) based on the obligation’s yield to maturity (or shorter period in the case of certain callable obligations). The amount of premium so amortized reduces the owner’s basis in such obligation for federal income tax purposes, though such amortized premium is not deductible for federal income tax purposes. This reduction in basis will increase the amount of any gain (or decrease the amount of any loss) recognized for federal income tax purposes upon a sale or other taxable disposition of the obligation. Special Counsel is not opining on the accounting for bond premium or the consequence to a Revenue Obligation purchaser of purchasing a Revenue Obligation with bond premium. Accordingly, persons considering the purchase of Revenue Obligations with bond premium should consult their own tax advisors with respect to the determination of bond premium on such Revenue Obligations for federal income tax purposes and with respect to the state and local tax consequences of owning and disposing of such Revenue Obligations. 298610182.5 64 Information Reporting and Backup Withholding Interest paid on the Revenue Obligations will be subject to information reporting in a manner similar to interest paid on taxable obligations. Although such reporting requirement does not, in and of itself, affect the excludability of such interest from gross income for federal income tax purposes, such reporting requirement causes the payment of the portion of each Installment Payment representing interest and distributable in respect of any Revenue Obligation to be subject to backup withholding if such interest is paid to beneficial owners who (a) are not “exempt recipients,” and (b) either fail to provide certain identifying information (such as the beneficial owner’s taxpayer identification number) in the required manner or have been identified by the IRS as having failed to report all interest and dividends required to be shown on their income tax returns. Generally, individuals are not exempt recipients, whereas corporations and certain other entities are exempt recipients. Amounts withheld under the backup withholding rules from a payment to a beneficial owner are allowed as a refund or credit against such beneficial owner’s federal income tax liability so long as the required information is furnished to the IRS. State Tax Exemption In the further opinion of Special Counsel, the portion of each Installment Payment representing interest and distributable in respect of any Revenue Obligation is exempt from personal income taxes imposed by the State of California. Future Developments Existing law may change to reduce or eliminate the benefit to owners of the Revenue Obligations of the exclusion of the portion of each Installment Payment representing interest and distributable in respect of any Revenue Obligation from gross income for federal income tax purposes or of the exemption of the portion of each Installment Payment representing interest and distributable in respect of any Revenue Obligation from State of California personal income taxation. Any proposed legislation, whether or not enacted, or administrative action, whether or not taken, could also affect the value and marketability of the Revenue Obligations. Prospective purchasers of the Revenue Obligations should consult their own tax advisors with respect to any proposed or future change in tax law. A copy of the form of opinion of Special Counsel relating to the Revenue Obligations is included in APPENDIX F hereto. VERIFICATION OF MATHEMATICAL COMPUTATIONS ___________________________________________, will verify the accuracy of mathematical computations concerning the adequacy of the maturing principal amounts of and interest earned on the Government Obligations deposited in the 2016A Escrow Fund, together with amounts held as cash therein, to provide for payment of interest and the prepayment prices (including accrued interest) of the Refunded 2016A Obligations through and on the Prepayment Date. The report of such firm will include the statement that the scope of their engagement was limited to verifying the mathematical accuracy of the computations contained in such schedules provided to them and that they have no obligation to update their report because of events occurring, or data or information coming to their attention, subsequent to the date of their report. 298610182.5 65 CONTINUING DISCLOSURE The District has covenanted for the benefit of holders and beneficial owners of the Revenue Obligations (a) to provide certain financial information and operating data (the “Annual Report”) relating to the District and the property in the District not later than eight months after the end of the District’s Fiscal Year (which currently would be March 1), commencing with the report for the 2024-25 Fiscal Year, and (b) to provide notices of the occurrence of certain enumerated events. The Annual Report will be filed by the District, or the Dissemination Agent on behalf of the District, with the Municipal Securities Rulemaking Board. The notices of enumerated events will be filed by or on behalf of the District with the Municipal Securities Rulemaking Board. The specific nature of the information to be contained in the Annual Report or the notices of enumerated events is set forth in the Continuing Disclosure Agreement. See APPENDIX D – “FORM OF CONTINUING DISCLOSURE AGREEMENT.” These covenants have been made in order to assist the Initial Purchaser in complying with S.E.C. Rule 15c2-12. RATINGS The Revenue Obligations will be rated “___” by Moody’s Investors Service, Inc. (“Moody’s”), “___” by S&P Global Ratings (“S&P”), and “___” by Fitch Ratings (“Fitch”). Such ratings reflect only the views of the rating agencies, and do not constitute a recommendation to buy, sell or hold the Revenue Obligations. Explanation of the significance of such ratings may be obtained only from the respective organizations at: Moody’s Investors Service, Inc. 7 World Trade Center, 250 Greenwich Street, New York, New York 10007, S&P Global Ratings, 55 Water Street, New York, New York 10041 and Fitch Ratings, One State Street Plaza, New York, New York 10004. There is no assurance that any such ratings will continue for any given period of time or that they will not be revised downward or withdrawn entirely by the respective rating agencies, if in the judgment of any such rating agency circumstances so warrant. Any such downward revision or withdrawal of such ratings may have an adverse effect on the market price of the Revenue Obligations. PURCHASE AND REOFFERING _____________. (the “Initial Purchaser”) has purchased the Revenue Obligations from the District at a competitive sale for a purchase price of $_____________ (representing the aggregate principal amount of the Revenue Obligations, plus a premium of $_____________, and less an Initial Purchaser’s discount of $_________). The public offering prices may be changed from time to time by the Initial Purchaser. The Initial Purchaser may offer and sell Revenue Obligations to certain dealers and others at prices lower than the offering prices shown on the inside cover page hereof.

ORANGE COUNTY SANITATION DISTRICT By: Board Chairperson 298610182.5 APPENDIX A ANNUAL COMPREHENSIVE FINANCIAL REPORT OF THE ORANGE COUNTY SANITATION DISTRICT FOR THE YEAR ENDED JUNE 30, 2024 298610182.5 [INSERT APPENDIX B] 298610182.5 [INSERT APPENDIX C] 298610182.5 [INSERT APPENDIX D] 298610182.5 E-1 APPENDIX E BOOK-ENTRY SYSTEM The description that follows of the procedures and recordkeeping with respect to beneficial ownership interests in the Revenue Obligations, payment of principal and interest evidenced by the Revenue Obligations to Participants or Beneficial Owners, confirmation and transfer of beneficial ownership interests in the Revenue Obligations, and other Revenue Obligation-related transactions by and between DTC, Participants and Beneficial Owners, is based on information furnished by DTC which the District and the Corporation each believes to be reliable, but the District and the Corporation take no responsibility for the completeness or accuracy thereof. The Depository Trust Company – Book-Entry System The Depository Trust Company (“DTC”), New York, NY, will act as securities depository for the securities (the “Revenue Obligations”). The Revenue Obligations will be issued as fully-registered securities registered in the name of Cede & Co. (DTC’s partnership nominee) or such other name as may be requested by an authorized representative of DTC. One fully-registered certificate will be issued for the Revenue Obligations in the aggregate principal amount of such issue, and will be deposited with DTC. DTC is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code, and a “clearing agency” registered pursuant to the provisions of Section 17A of the Securities Exchange Act of 1934. DTC holds and provides asset servicing for over 3.5 million U.S. and non-U.S. equity issues, corporate and municipal debt issues, and money market instruments (from over 100 countries) that DTC’s participants (“Direct Participants”) deposit with DTC. DTC also facilitates the post-trade settlement among Direct Participants of sales and other securities transactions in deposited securities, through electronic computerized book-entry transfers and pledges between Direct Participants’ accounts. This eliminates the need for physical movement of securities certificates. Direct Participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations, and certain other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation (“DTCC”). DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to the DTC system is also available to others such as both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, and clearing corporations that clear through or maintain a custodial relationship with a Direct Participant, either directly or indirectly (“Indirect Participants”). DTC has a Standard & Poor’s rating of “AA+.” The DTC Rules applicable to its Participants are on file with the Securities and Exchange Commission. More information about DTC can be found at www.dtcc.com. The information on such website is not incorporated herein by such reference or otherwise. Purchases of Revenue Obligations under the DTC system must be made by or through Direct Participants, which will receive a credit for the Revenue Obligations on DTC’s records. The ownership interest of each actual purchaser of each Revenue Obligation (“Beneficial Owner”) is in turn to be recorded on the Direct and Indirect Participants’ records. Beneficial Owners will not receive written confirmation from DTC of their purchase. Beneficial Owners are, however, expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the Direct or Indirect Participant through which the Beneficial Owner entered into the transaction. Transfers of ownership interests in the Revenue Obligations are to be accomplished by entries made on the books of Direct and Indirect Participants acting on behalf of Beneficial Owners. Beneficial Owners will not receive 298610182.5 E-2 certificates representing their ownership interests in the Revenue Obligations, except in the event that use of the book-entry system for the Revenue Obligations is discontinued. To facilitate subsequent transfers, all Revenue Obligations deposited by Direct Participants with DTC are registered in the name of DTC’s partnership nominee, Cede & Co. or such other name as may be requested by an authorized representative of DTC. The deposit of Revenue Obligations with DTC and their registration in the name of Cede & Co. or such other nominee do not effect any change in beneficial ownership. DTC has no knowledge of the actual Beneficial Owners of the Revenue Obligations; DTC’s records reflect only the identity of the Direct Participants to whose accounts such Revenue Obligations are credited, which may or may not be the Beneficial Owners. The Direct and Indirect Participants will remain responsible for keeping account of their holdings on behalf of their customers. Conveyance of notices and other communications by DTC to Direct Participants, by Direct Participants to Indirect Participants, and by Direct Participants and Indirect Participants to Beneficial Owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time. Beneficial Owners of Revenue Obligations may wish to take certain steps to augment transmission to them of notices of significant events with respect to the Revenue Obligations, such as prepayments, tenders, defaults, and proposed amendments to the security documents. For example, Beneficial Owners of Revenue Obligations may wish to ascertain that the nominee holding the Revenue Obligations for their benefit has agreed to obtain and transmit notices to Beneficial Owners, in the alternative, Beneficial Owners may wish to provide their names and addresses to the registrar and request that copies of the notices be provided directly to them. Prepayment notices shall be sent to DTC. If less than all of the Revenue Obligations within an issue are being prepaid, DTC’s practice is to determine by lot the amount of the interest of each Direct Participant in such issue to be prepaid. Neither DTC nor Cede & Co. (nor such other DTC nominee) will consent or vote with respect to the Revenue Obligations unless authorized by a Direct Participant in accordance with DTC’s MMI Procedures. Under its usual procedures, DTC mails an Omnibus Proxy to the District as soon as possible after the record date. The Omnibus Proxy assigns Cede & Co.’s consenting or voting rights to those Direct Participants to whose accounts the Revenue Obligations are credited on the record date (identified in a listing attached to the Omnibus Proxy). Prepayments with respect to the Revenue Obligations will be made to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC. DTC’s practice is to credit Direct Participants’ accounts, upon DTC’s receipt of funds and corresponding detail information from the District or the Trustee on payable date in accordance with their respective holdings shown on DTC’s records. Payments by Participants to Beneficial Owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of such Participant and not of DTC, nor its nominee, the Trustee, or the District, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of prepayment proceeds, distributions, and dividend payments to Cede & Co. (or such other nominee as may be requested by an authorized representative of DTC) is the responsibility of the District or the Trustee, disbursement of such payments to Direct Participants will be the responsibility of DTC, and disbursement of such payments to the Beneficial Owners will be the responsibility of Direct and Indirect Participants. 298610182.5 E-3 DTC may discontinue providing its services as securities depository with respect to the Revenue Obligations at any time by giving reasonable notice to the District or the Trustee. Under such circumstances, in the event that a successor securities depository is not obtained, Revenue Obligations are required to be printed and delivered. The District may decide to discontinue use of the system of book-entry-only transfers through DTC (or a successor securities depository). In that event, Revenue Obligations will be printed and delivered to DTC. The information in this section concerning DTC and DTC’s book-entry system has been obtained from sources that the District believes to be reliable, but the District takes no responsibility for the accuracy thereof. Discontinuance of DTC Services In the event (i) DTC determines not to continue to act as securities depository for the Revenue Obligations, (ii) DTC shall no longer act and give notice to the Trustee of such determination or (iii) the District determines that it is in the best interest of the Beneficial Owners that they be able to obtain Revenue Obligations and delivers a written certificate to the Trustee to that effect, DTC services will be discontinued. If the District determines to replace DTC with another qualified securities depository, the District shall prepare or direct the preparation of a new single, separate, fully registered Revenue Obligation for each of the maturities of the Revenue Obligations, registered in the name of such successor or substitute qualified securities depository or its nominee. If the District fails to identify another qualified securities depository to replace DTC then the Revenue Obligations shall no longer be restricted to being registered in the certificate registration books in the name of Cede & Co., but shall be registered in such names as are requested in a certificate of the District, in accordance with the Trust Agreement. All Revenue Obligations may be presented for transfer by the Owner thereof, in person or by his attorney duly authorized in writing, at the Principal Office of the Trustee, on the books required to be kept by the Trustee pursuant to the provisions of the Trust Agreement, upon surrender of such Certifications for cancellation accompanied by delivery of a duly executed written instrument of transfer in a form acceptable to the Trustee. The Trustee may treat the Owner of any Revenue Obligation as the absolute owner of such Revenue Obligation for all purposes, whether or not such Revenue Obligation shall be overdue, and the Trustee shall not be affected by any knowledge or notice to the contrary; and payment of the interest and principal evidenced by such Revenue Obligation shall be made only to such Owner, which payments shall be valid and effectual to satisfy and discharge the liability evidenced by such Revenue Obligation to the extent of the sum or sums so paid. Whenever any Revenue Obligations shall be surrendered for transfer, the Trustee shall execute and deliver new Revenue Obligations representing the same principal amount in Authorized Denominations. The Trustee shall require the payment of any Owner requesting such transfer of any tax or other governmental charge required to be paid with respect to such transfer. Revenue Obligations may be presented for exchange at the Principal Office of the Trustee for a like aggregate principal amount of Revenue Obligations of other Authorized Denominations. The Trustee shall require the payment by the Owner requesting such exchange of any tax or other governmental charge required to be paid with respect to such exchange. The Trustee shall not be required to transfer or exchange any Revenue Obligation during the period in which the Trustee is selecting Revenue Obligations for prepayment, nor shall the Trustee be required to transfer or exchange any Revenue Obligation or portion thereof selected for prepayment from and after the date of mailing the notice of prepayment thereof. 298610182.5 F-1 APPENDIX F FORM OF APPROVING OPINION OF SPECIAL COUNSEL Upon the execution and delivery of the Revenue Obligations, Norton Rose Fulbright US LLP, Los Angeles, California, Special Counsel to the District, will render its final approving opinion with respect to the Revenue Obligations in substantially the following form: [Date of Delivery] Orange County Sanitation District 18480 Bandilier Circle Fountain Valley, California 92708 $___________ Orange County Sanitation District Wastewater Refunding Revenue Obligations Series 2025A Ladies and Gentlemen: We have acted as Special Counsel in connection with the $___________ aggregate principal amount of Orange County Sanitation District Wastewater Refunding Revenue Obligations, Series 2025A (the “Revenue Obligations”) which are certificates of participation that evidence direct, fractional undivided interests of the Owners thereof in the installment payments (the “Installment Payments”), and the interest thereon, to be made by the Orange County Sanitation District (the “District”) pursuant to the Installment Purchase Agreement, dated as of November 1, 2025 (the “Installment Purchase Agreement”), by and between the District and the Orange County Sanitation District Financing Corporation (the “Corporation”). Pursuant to the Master Agreement for District Obligations, dated as of August 1, 2000 (the “Master Agreement”), by and between the District and the Corporation, the District has established conditions and terms upon which obligations such as the Installment Payments, and the interest thereon, will be incurred and secured. Installment Payments under the Installment Purchase Agreement are payable solely from Net Revenues as provided in the Installment Purchase Agreement, consisting primarily of all income and revenue received by the District from the operation or ownership of the Wastewater System of the District (the “Wastewater System”) remaining after payment of Maintenance and Operation Costs. Capitalized terms used and not otherwise defined herein shall have the meanings ascribed to such terms in the Installment Purchase Agreement. The Revenue Obligations are to be executed and delivered pursuant to a Trust Agreement, dated as of November 1, 2025 (the “Trust Agreement”), by and among the District, the Corporation and U.S. Bank Trust Company, National Association, as successor trustee (the “Trustee”). Proceeds from the sale of the Revenue Obligations will be used, together with other available funds, to (i) prepay [all/a portion] of the District’s Wastewater Refunding Revenue Obligations, Series 2016A in the aggregate principal amount of $[___] (the “Refunded 2016A Obligations”) and (ii) pay the costs incurred in connection with the execution and delivery of the Revenue Obligations. As Special Counsel, we have examined copies certified to us as being true and complete copies of the Master Agreement, the Trust Agreement and the Installment Purchase Agreement and the proceedings of the District in connection with the execution and delivery of the Revenue Obligations. We have also examined such certificates of officers of the District, the Corporation and others as we have considered necessary for the purposes of this opinion. 298610182.5 F-2 Based upon the foregoing, we are of the opinion that: 1. The Master Agreement, the Installment Purchase Agreement and the Trust Agreement each has been duly and validly authorized, executed and delivered by the District and, assuming the Master Agreement, the Installment Purchase Agreement and the Trust Agreement each constitutes the legally valid and binding obligation of the other parties thereto, each constitutes the legally valid and binding obligation of the District, enforceable against the District in accordance with its respective terms. 2. The obligation of the District to pay the Installment Payments, and the interest thereon, and other payments required to be made by it under the Installment Purchase Agreement is a special obligation of the District payable, in the manner provided in the Installment Purchase Agreement, solely from Net Revenues and other funds provided for in the Installment Purchase Agreement lawfully available therefor. 3. Assuming due authorization, execution and delivery of the Trust Agreement and the Revenue Obligations by the Trustee, the Revenue Obligations are entitled to the benefits of the Trust Agreement. 4. Under existing statutes, regulations, rulings and judicial decisions, and assuming compliance by the District with certain covenants in the Trust Agreement, the Tax Certificate and other documents pertaining to the Revenue Obligations and requirements of the Internal Revenue Code of 1986 regarding the use, expenditure and investment of proceeds of the Revenue Obligations and the timely payment of certain investment earnings to the United States, the portion of each Installment Payment representing interest and distributable in respect of any Revenue Obligation is not includable in the gross income of the owners of the Revenue Obligations for federal income tax purposes. Failure to comply with such covenants and requirements may cause the portion of each Installment Payment representing interest and distributable in respect of any Revenue Obligation to be included in gross income retroactive to the date of execution and delivery of the Revenue Obligations. 5. Under existing law, the portion of each Installment Payment representing interest and distributable in respect of any Revenue Obligation is not treated as an item of tax preference for purposes of the federal alternative minimum tax on individuals. We express no opinion regarding the applicability of the corporate alternative minimum tax to the adjusted financial statement income of any owner of the Revenue Obligations. 6. Under existing law, the portion of each Installment Payment representing interest and distributable in respect of any Revenue Obligation is exempt from personal income taxes imposed by the State of California. Except as stated in paragraphs 4, 5 and 6 above, we express no opinion as to any federal or state tax consequence of the ownership or disposition of the Revenue Obligations or the receipt or accrual of the portion of each Installment Payment representing interest and distributable in respect of any Revenue Obligation. Further, certain requirements and procedures contained or referred to in the Trust Agreement, the Installment Purchase Agreement or in other documents pertaining to the Revenue Obligations may be changed, and certain actions may be taken, under the circumstances and subject to the terms and conditions set forth in such documents, upon the advice or with the approving opinion of counsel nationally recognized in the area of tax-exempt obligations. We express no opinion as to the effect of any change to any document pertaining to the Revenue Obligations or of any action taken or not taken where such change is made or action is taken or not taken without our approval or in reliance upon the advice of counsel other than 298610182.5 F-3 ourselves with respect to the exclusion from gross income of the portion of each Installment Payment representing interest and distributable in respect of any Revenue Obligation for federal income tax purposes. The rights of the owners of the Revenue Obligations and the enforceability of the Revenue Obligations, the Master Agreement, the Trust Agreement and the Installment Purchase Agreement may be subject to bankruptcy, insolvency, reorganization, moratorium and other similar laws affecting creditors’ rights heretofore or hereafter enacted and may also be subject to the exercise of judicial discretion in appropriate cases. The enforceability of the Revenue Obligations, the Master Agreement, the Trust Agreement and the Installment Purchase Agreement is subject to the effect of general principles of equity, including, without limitation, concepts of materiality, reasonableness, good faith and fair dealing, to the possible unavailability of specific performance or injunctive relief, regardless of whether considered in a proceeding in equity or at law, and to the limitations on legal remedies against governmental entities in California. No opinion is expressed herein on the accuracy, completeness or fairness of the Official Statement or other offering material relating to the Revenue Obligations. Our opinions are based on existing law, which is subject to change. Such opinions are further based on our knowledge of facts as of the date hereof. We assume no duty to update or supplement our opinions to reflect any facts or circumstances that may hereafter come to our attention or to reflect any changes in any law that may hereafter occur or become effective. Moreover, our opinions are not a guarantee of result; rather, such opinions represent our legal judgment based upon our review of existing law that we deem relevant to such opinions and in reliance upon the representations and covenants referenced above.

FROM:Rob Thompson, General Manager Originator: Lorenzo Tyner, Assistant General Manager SUBJECT: RELINQUISHMENT AND DISPOSITION PROCEDURES FOR VACATION AND SALE OF EXCESS EASEMENTS INTERESTS GENERAL MANAGER'S RECOMMENDATION RECOMMENDATION: Recommend to the Board of Directors to: Adopt Resolution No.OC SAN 25-XX titled,“A Resolution of the Board of Directors of Orange County Sanitation District Permitting the Establishment of Relinquishment and Disposition Procedures for Vacation and Sale of Excess Easement Interests.” BACKGROUND Orange County Sanitation District (OC San)receives requests from private property owners and public entities to relinquish its rights to abandoned sewer line easements.Requests for relinquishment of excess land,in particular easement interests,are typically made by or on behalf of the underlying or adjoining fee interest real property owner. RELEVANT STANDARDS ·Protect OC San assets ·Ensure the public’s money is wisely spent PROBLEM The General Manager currently does not have the authority to enter into cost recovery reimbursement agreements within the limits of his established delegated authority.As a result, processing easement relinquishment requests from private owners or developers requires individual Board approval to recover the costs associated with the transaction.This creates uncertainty due to a lack of standardization in managing reimbursement agreements and cost recovery,potentially exposing the agency to risks related to unauthorized gifts of public funds. In addition,the current process lacks transparency to the public whether there are costs associated with their request and subsequent recovery efforts. Orange County Sanitation District Printed on 9/3/2025Page 1 of 3 powered by Legistar™ File #:2025-4457 Agenda Date:9/10/2025 Agenda Item No:9. PROPOSED SOLUTION Authorize the General Manager to enter into agreements with property owners requesting relinquishment of OC San’s excess easement interests for fair market value as determined under established policies and procedures,provided that the payment for said relinquished easement does not exceed One Hundred Fifty Thousand Dollars ($150,000). TIMING CONCERNS Relinquishment requests can take six to nine months to complete the due diligence required before they are brought to the Board of Directors for approval.Adoption of the Resolution will streamline operations,reduce delays,and enhance the agency’s responsiveness while maintaining necessary legal safeguards. RAMIFICATIONS OF NOT TAKING ACTION If no action is taken,processing relinquishment requests will be delayed because each individual request requires Board of Directors approval,leading to inefficiencies and frustration among private property owners and developers.This also increases the risk of non-compliance with laws governing the use of public funds,including potential unauthorized gifts of public funds.Furthermore,the lack of transparency regarding cost responsibilities may result in poor customer service and diminished public trust. PRIOR COMMITTEE/BOARD ACTIONS N/A ADDITIONAL INFORMATION This policy would enable more timely and efficient processing of relinquishment requests from private owners or developers.Staff worked with legal counsel to develop this approach.The General Manager would be authorized to enter into cost recovery agreements,subject to internal approval, ensuring compliance with applicable laws to prevent unauthorized gifts of public funds.This policy will also improve transparency and customer service by clarifying when costs are associated with relinquishment requests.All relinquishment requests will undergo a due diligence process to confirm the property is no longer of beneficial use to OC San. CEQA N/A FINANCIAL CONSIDERATIONS Cost recovery would be limited to direct fees and costs borne of relinquishment requests.There is no budgetary impact.

Priority is given to public agencies. A direct negotiated sale based on current appraised fair market value to an underlying or adjoining property owner may be accomplished in accordance with the procedures outlined below. Relinquishments and sale of real property interests must be done in accordance with all applicable rules, laws and regulations, including California Health & Safety (H&S) Code Sections 4700 et seq., more particularly H&S Code Sections 4730.65, 4730.66, 4740 4743 and other laws applicable the disposition of land.

Pursuant to H&S Code Section 4743, OC San “may sell, lease, or otherwise dispose of any property of the district or any interest therein whenever it is no longer required for the purposes of the district, or when its use may be permitted without interfering with its use by the district.” B.

Upon such submission, OC San shall follow the policies and procedures outlined herein. 2. The Online Portal shall also include a search engine where users may access recorded documents associated with their property address. C. Correspondence.

OC San will evaluate real property interest requested to be relinquished to determine if the interest is no longer needed for OC San purposes and provide a recommendation on whether the request should be further processed. 3. When a recommendation to further process the request has been made, OC San will: a) Request applicable survey, valuation of interest, and any other pertinent actions to facilitate the transaction. b) Commence negotiation and preparation of the agreement terms for transferring real property interest will occur. c) Submit the Agreement for the purchase and sale of the real property interest to the General Manager where the payment for said relinquished easement does not exceed One Hundred Fifty Thousand Dollars ($150,000.00).

Excess Land Evaluation And Investigation. Evaluation must be undertaken of the property interest, the reason for the disposition of the property interest, the reason the property interest is no longer needed for OC San’s use or purposes, the reason why the retained property interest is adequate for the facility and use, under current standards, and any additional background information, to establish written finding to support the excess easement declaration. In addition, a evaluation will be considered if there any reservations or exceptions that need to be assumed by the buyer or relocations of property interests instead of relinquishment. NOTE: A case-by-case consideration must be made on whether the California Surplus Land Act (the “Act”) applies to a particular situation. General rule is that disposition of surplus land, land owned in fee, by a local agency is subject to the Act unless a statutory exemption applies to the disposition. If a particular situation is determined to be subject to the Act and is eligible for an exemption under the Act or other express statutory basis, then the procedure in Section F.1. below must 55880.00700\44134708.2 3 be followed. E. Costs and Timeframes. The requesting party/buyer of the easement is responsible for paying for all costs associated with the purchase and sale, which includes staff costs, administrative costs and professional services costs. Due diligence must be completed to accurately identify the property interest. 1. A survey may be required, at the buyer’s cost, to determine the exact size and dimensions of the easement. A legal description and plat map must be provided to OC San. Timeframe for survey work: 5-7 weeks 2. Other environmental or statutory reviews (i.e. CEQA and Surplus Lands Act) may be required and at the buyer’s cost and expense. Timeframe: Varies, a minimum of 9 months. F. Valuation and Timeframes. As part of the due diligence, valuation of the interest must be established. Valuation of easement is established by conducting an appraisal based on state guidelines (or federal if applicable). An appraisal must be done on behalf of OC San, at the buyer’s costs and expense, by an OC San approved appraiser. The inquiring party must pay for the appraisal report on OC San’s behalf and names OC San as the client. This is to establish the purchase price amount for the interest(s) to be relinquished and conveyed. OC San will procure the appraiser pursuant to its standard procurement policies. OC San will provide to the selected appraiser information about the easement to be appraised and the rights to be conveyed by OC San. Appraiser determines the fair market value of the easement and provides the appraisal report to OC San for its review. Timeframe: 7 weeks G. Preparation and Processing of Documentation. The documents for the excess declaration, purchase, sale and relinquishment of the easement will be prepared if OC San determines that the easement interest can be relinquished and after Buyer provides confirmation that it will purchase the easement interest. 1. IF IT HAS BEEN DETERMINED THAT THE SURPLUS LAND ACT IS APPLICABLE, then a declaration of exempt surplus land by Resolution shall be made by OC San’s Board of Directors. A Declaration of Exempt Surplus Land Resolution must be submitted to the California Department of Housing and Community Development (HCD) at least thirty (30) days before 55880.00700\44134708.2 4 disposition when surplus land is deemed as exempt under the Surplus Land Act and supported with written findings.

A draft of the resolution should be sent to HCD for a preview. HCD requires at least 30 days to complete the review. 2. A Purchase and Sale Agreement between OC San and the Buyer and conveyance documents will be prepared and finalized for execution, subject to OC San Board approval. Timeframe: minimum of 6 weeks for preparation of and finalizing the documents 3. Where the payment for said relinquished easement exceeds One Hundred Fifty Thousand Dollars ($150,000.00), a Resolution and Board Agenda report regarding the approval of the Agreement are prepared and submitted to the Board.

Timeframe: 8 weeks for approval of the documents H. Closing Actions. After the item is approved by the Board and the Agreement is fully executed, escrow is opened and closed for the purchase and sale of the easement within the timeframe provided in the Purchase and Sale Agreement. 55880.00700\43086351.1 1 PURCHASE AND SALE AGREEMENT This PURCHASE AND SALE AGREEMENT (“Agreement”) by and between the Orange County Sanitation District, a California special district, (“Seller”) and [Buyer’s Name and legal capacity] (“Buyer”), each of them a “Party” and jointly the “Parties”, is entered into as of the date the last of the Parties executes this Agreement (“Effective Date”).
