FROM:Robert Thompson, General Manager Originator: Wally Ritchie, Director of Finance SUBJECT: AGREEMENT WITH IRVINE RANCH WATER DISTRICT FOR THE COLLECTION OF REGIONAL TREATMENT FEES FOR FISCAL YEAR 2026-27 GENERAL MANAGER'S RECOMMENDATION RECOMMENDATION: Recommend to the Board of Directors to: Approve and authorize the General Manager to execute the Implementation Agreement between Orange County Sanitation District and Irvine Ranch Water District,in a form approved by General Counsel. BACKGROUND In November 2025,the Board of Directors approved the Flow Exchange Agreement between Orange County Sanitation District (OC San)and Irvine Ranch Water District (IRWD).This agreement simplified existing arrangements under the guiding principle for wastewater to flow by gravity to existing facilities for treatment. OC San has two revenue areas -Consolidated Revenue Area (CRA)and Revenue Area 14 (RA14). The Flow Exchange Agreement updated the revenue area boundary so that customers whose wastewater flows by gravity to OC San are in the CRA and customers whose wastewater flows by gravity to IRWD are in RA14.This boundary change goes into effect on July 1,2026,and customers in each revenue area will continue to pay regional transmission and wastewater treatment fees to the associated agency thereafter. Those customers that shifted to CRA were not part of OC San’s previous Proposition 218 process; therefore,OC San cannot assess its current service fees to these customers until a new Proposition 218 process is complete and adopted with a planned effective date of July 1, 2027. RELEVANT STANDARDS ·Maintain collaborative and cooperative relationships with regulators,stakeholders,and neighboring communities ·Maintain a culture of improving efficiency to reduce the cost to provide the current service level or standard Orange County Sanitation District Printed on 6/15/2026Page 1 of 3 powered by Legistar™ File #:2026-4938 Agenda Date:6/24/2026 Agenda Item No:2. PROBLEM Customers that transferred from RA14 to CRA of OC San cannot be assessed its sewer service fees by OC San until a new rate setting and Proposition 218 process has been completed and adopted. OC San assesses fees differently than IRWD and does not have a good way to assess these customers their current fees. PROPOSED SOLUTION Approve the Implementation Agreement to allow IRWD to continue collection of regional transmission and wastewater treatment fees from customers that transferred from RA14 to CRA and remit the revenue to OC San. TIMING CONCERNS The Implementation Agreement needs to be in place before July 1,2026,to ensure continued collection of regional transmission and wastewater treatment fees to customers within the transfer areas. RAMIFICATIONS OF NOT TAKING ACTION OC San will not be able to collect revenue from the customers within the transfer area until the new Proposition 218 process has been completed and is adopted. PRIOR COMMITTEE/BOARD ACTIONS November 2025 -Approved and authorized the General Manager to execute the Flow Exchange Agreement between Orange County Sanitation District and Irvine Ranch Water District,in a form approved by General Counsel;and Approved and authorized the General Manager to execute the GAP Flows Agreement between Orange County Sanitation District,Irvine Ranch Water District,and Orange County Water District, for a term of 20 years, in a form approved by General Counsel. ADDITIONAL INFORMATION The proposed Implementation Agreement allows for IRWD to continue to collect current regional wastewater transmission,treatment,and disposal fees from customers within the agreement transfer areas and remit the revenue on behalf of OC San for Fiscal Year 2026-27.IRWD will retain five percent of the revenue for administrative costs and remit the remainder to OC San. CEQA N/A FINANCIAL CONSIDERATIONS If the Implementation Agreement is not approved,OC San will forego potential revenue from the new direct customer base. Orange County Sanitation District Printed on 6/15/2026Page 2 of 3 powered by Legistar™ File #:2026-4938 Agenda Date:6/24/2026 Agenda Item No:2. ATTACHMENT The following attachment(s)may be viewed on-line at the OC San website (www.ocsan.gov)with the complete agenda package: ·Implementation Agreement Orange County Sanitation District Printed on 6/15/2026Page 3 of 3 powered by Legistar™ IMPLEMENTATION AGREEMENT (Section 3.3.3 of the 2025 Flow Exchange Agreement) This Implementation Agreement (“Agreement”), is dated June 24, 2026 and is between the Irvine Ranch Water District, a California Water District, formed and existing under Division 13 of the California Water Code (“IRWD”), and the Orange County Sanitation District, a County Sanitation District, formed and existing under Chapter 3 of Part 3 of Division 5 of the California Health and Safety Code (“OC San”). OC San and IRWD are sometimes referred to individually as a “Party” and collectively as the “Parties.” IRWD and OC San have cooperated historically to provide customers local collection, regional transmission, and treatment of wastewater. The Parties entered into a Flow Exchange Agreement dated December 1, 2025. Section 3.3.3 of the Flow Exchange Agreement provided that IRWD and OC San would on July 1, 2026 (the “Effective Date”) reallocate these responsibilities with their customers in the IRWD-to-OC San Transfer Areas1 as follows: (1) IRWD would maintain Local Collection responsibility for the Transferred Areas and (2) OC San would assume Regional Transmission and Wastewater Treatment responsibilities. Customers in the Transfer Areas would become customers of both Parties on the Effective Date. OC San is in the process of updating its Wastewater Treatment fees district-wide, and until those fees are updated and imposed on the IRWD-to-OC San Transfer Areas as contemplated in Section 3.3.3 , the Parties intend by this Agreement to provide for IRWD to continue collecting Wastewater Treatment Fees (“Fees”), and remitting them to OC San in order to cover the costs of Regional Transmission and Wastewater Treatment service, pursuant to Government Code section 53755 and Health and Safety Code Section 5470 et seq. The Parties therefore agree as follows: 1. Term. This Agreement will be effective for Regional Transmission and Wastewater Treatment services provided from July 1, 2026 through June 30, 2027 (the “Deferral Period”), and will expire upon the date that IRWD remits all Fees and provides the corresponding accounting summary (as described below). 2. Implementation of Section 3.3.3 of the Flow Exchange Agreement. The provision of Section 3.3.3 of the Flow Exchange Agreement providing for OC San’s adoption of a “new and separate fee” to customers in the IRWD-to-OC San Transfer Areas is hereby deferred during the Deferral Period. Except as expressly amended by this Agreement, prior agreements between the Parties, including the Flow Exchange Agreement, will otherwise remain unchanged and in full force and effect. Nothing herein shall change the characterization of any customer for any other purpose or agreement, including the Flow Exchange Agreement and any other agreement between IRWD and OC San. 3. Fee Collection Responsibilities. IRWD shall continue to impose and collect the Fees from customers within the IRWD-to-OC San Transfer Areas at the IRWD rates for Fiscal Year 2026- 2027, and then remit those Fees to OC San, less the administrative cost described below. IRWD shall be solely responsible for all administrative and billing responsibilities associated with collecting and remitting the Fees, including pursuing delinquencies in the same manner as IRWD customarily pursues delinquencies. 1 All capitalized terms in this Agreement will have the same meaning as in the Flow Exchange Agreement, unless separately defined here. 55880.00600\45090605.2 4. Remittance of Collected Fees, Accounting and Reporting. IRWD shall provide to OC San quarterly accounting summaries, which will identify Fees billed, Fees collected, administrative retention amounts, delinquent amounts, and net amounts remitted to OC San. IRWD shall remit the summaries and Fees to OC San on a quarterly basis, within 15 days of the end of each quarter. To avoid doubt, the remittance dates shall be: Service Period Remittance Date July 2026 – September 2026 October 15, 2026 October 2026 – December 2026 January 15, 2027 January 2027 – March 2027 April 15, 2027 April 2027 – June 2027 July 15, 2027 5. Administrative Cost Retention. In consideration for performing the revenue collection, accounting, and remittance obligations under this Agreement, IRWD shall retain five percent (5%) of the Fees collected within the IRWD-to-OC San Transfer Areas. 6. Indemnification. OC San shall defend, indemnify, and hold IRWD and its officials, officers, employees and agents free and harmless from any claim, loss, damage, or injury arising out of or in connection with the execution or performance of this Agreement, including without limitation the payment of attorneys’ fees.

FROM:Robert Thompson, General Manager Originator: Mike Dorman, Director of Engineering SUBJECT: AGREEMENT WITH IRVINE RANCH WATER DISTRICT MOOTING DEFUNCT PRIOR CONTRACTS AND TERMINATING SURVIVAL PROVISIONS GENERAL MANAGER'S RECOMMENDATION RECOMMENDATION: Recommend to the Board of Directors to: Approve and authorize the General Manager to execute the Agreement Mooting Defunct Prior Contracts and Terminating Survival Provisions between Orange County Sanitation District and Irvine Ranch Water District, in a form approved by General Counsel. BACKGROUND Orange County Sanitation District (OC San)and Irvine Ranch Water District (IRWD)have had cooperative agreements dating back to the early 1960s.IRWD formally joined the Joint Powers Authority that defined the County Sanitation Districts of Orange County (OC San’s predecessor agency)in 1986 as County Sanitation District of Orange County No.14.Over the course of this relationship,the two agencies have entered into dozens of agreements relating to joint projects, cooperative efforts,conveyances,and financing.As these many agreements between OC San and IRWD have been approved,it has become increasingly more difficult to effectively monitor and track which provisions remain operable and which have been terminated, expired, or superseded. The OC San Board of Directors took two major initial steps toward these ends in November 2025 with its approval of the new Flow Exchange Agreement,which ratified and clarified service responsibility and aligned revenue collection in some of the shared service areas,and provided for OC San’s service to the LAWRP Area through the annexation of the LAWRP Area into OC San;and the Green Acres Project (GAP)Flows Agreement,which established rights and duties with respect to IRWD’s supply of recycled water to OCWD’s GAP or Groundwater Replenishment System (GWRS),and IRWD’s capacity to discharge recycled water into the OC San ocean outfall system.These consolidated and updated the prior agreements between the agencies relating to these topics. Staff and counsel for both agencies have continued working cooperatively to review the remaining agreements.This proposed Agreement is the next logical step as it formally removes those agreements that have been terminated, expired, superseded, or are no longer applicable. Orange County Sanitation District Printed on 6/15/2026Page 1 of 3 powered by Legistar™ File #:2026-4961 Agenda Date:6/24/2026 Agenda Item No:3. RELEVANT STANDARDS ·Maintain collaborative and cooperative relationships with regulators,stakeholders,and neighboring communities ·Maintain a culture of improving efficiency to reduce the cost to provide the current service level or standard PROBLEM OC San and IRWD have a long history of working cooperatively as reflected by their numerous agreements.However,as layers of agreements have developed,they have lacked internal reference,cross references,and a coherent chronology.Accordingly,it requires significant effort to determine where the parties stand,poses challenges for future collaboration,and hinders efficient interagency governance moving forward. PROPOSED SOLUTION Approve the proposed Agreement Mooting Defunct Prior Contracts and Terminating Survival Provisions that identifies all prior agreements between the parties that are defunct and no longer operative.It classifies as defunct all agreements that have expired or been superseded and all agreements with obligations that have been performed or otherwise satisfied.It also ends agreements with unnecessary surviving provisions relating to representations,warranties,covenants, indemnification, disclosure, notice, confidentiality, and severability. TIMING CONCERNS Significant effort has been made in the review of these prior agreements.Delaying approval of this agreement may stall progress on active agreements and result in repeated staff efforts. RAMIFICATIONS OF NOT TAKING ACTION If no action is taken,OC San and IRWD will continue relying on agreements in their current state.As future agreements are required,additional effort and associated costs may be required,and efficient interagency governance may be impacted.In addition,the benefits of staffs’and counsels’efforts to clarify existing positions are likely to be lost with time. PRIOR COMMITTEE/BOARD ACTIONS May 2026 -Authorized staff to take all steps necessary to work with Irvine Ranch Water District and the Orange County Local Agency Formation Commission to bring to effect the annexation of the area serviced by the Los Alisos Water Recycling Plant to Orange County Sanitation District;Authorized the General Manager to execute associated Annexation documents in a form approved by General Counsel;and Adopted Resolution No.OC SAN 26-07,entitled:“A Resolution of the Board of Directors of the Orange County Sanitation District authorizing initiation of proceedings and requesting the Orange County Local Agency Formation Commission to undertake proceedings for the Annexation to the Orange County Sanitation District, of territory in the Irvine Ranch Water District. November 2025 -Approved and authorized the General Manager to execute the Flow Exchange Orange County Sanitation District Printed on 6/15/2026Page 2 of 3 powered by Legistar™ File #:2026-4961 Agenda Date:6/24/2026 Agenda Item No:3. November 2025 -Approved and authorized the General Manager to execute the Flow Exchange Agreement between Orange County Sanitation District and Irvine Ranch Water District,in a form approved by General Counsel;and Approved and authorized the General Manager to execute the GAP Flows Agreement between Orange County Sanitation District,Irvine Ranch Water District,and Orange County Water District, for a term of 20 years, in a form approved by General Counsel. ADDITIONAL INFORMATION Going forward,the parties’contractual relationship will be governed solely by their currently operative agreements.Though this agreement does not make changes to these operative agreements,the mooting of the defunct agreements and terminated survival provisions provides transparency to both agencies and helps ensure a common understanding of current obligations. The effort to review those agreements that remain will continue.As all outstanding obligations and provisions are identified,the intention is to consolidate these elements,where beneficial,into a modern, unified framework that can be easily managed and operated. CEQA N/A FINANCIAL CONSIDERATIONS The proposed agreement will streamline future interagency coordination,thereby reducing administrative costs.

OC San was created under the California County Sanitation District Act (California Health and Safety Code Section 4700 et seq.), which empowers it to (i) own, control, manage, and dispose of any interest in real or personal property necessary or convenient for the construction, maintenance, and operation of a sewerage system and sewage disposal or treatment plant (Id. at Section 4740) and (ii) acquire, construct, and complete within or without the district, sewage collection, treatment and disposal works, including sewage treatment plants, outfalls, intercepting, collecting and lateral sewers, pipes, pumps, machinery, easements, rights-of-way, and other works, property or structures necessary or convenient for sewage collection, treatment, and disposal (Id. at Section 4741). B. IRWD was created under the California Water District Law (California Water Code Section 34000, et seq.) which empowers it to carry out the powers and purposes granted to it under the California Water Code, including the treatment and reuse of wastewater. C. OC San is the successor-in-interest to nine County Sanitation Districts of Orange County (“CSDOC”), which consolidated to form OC San in 1998. D. The Parties have a long history of working cooperatively on regional wastewater infrastructure and services, including the planning, development, ownership, operation, financing, and use of wastewater transmission, treatment, disposal, and related facilities, as reflected in numerous agreements entered into over time. The Parties have identified certain prior agreements between them that are defunct and no longer operative, as listed in Exhibit A (“Defunct Agreements”). All of the Defunct Agreements have expired or been superseded, or their obligations have been performed or otherwise satisfied. However, the Defunct Agreements may contain some standard provisions intended to survive the full performance, expiration, or supersession of a now Defunct Agreement, including but not limited to any obligations between the Parties relating to representations, warranties, covenants, indemnification, disclosure, notice, confidentiality, and severability (“Survival Provisions”). E. The Parties intend by this Agreement to declare moot and inoperative all Defunct Agreements between the Parties, as identified in Exhibit A, and to terminate and extinguish any Survival Provisions of such Defunct Agreements that might otherwise be construed as remaining in effect, so that no such agreements or provisions have any further force or effect, and the Parties’ contractual relationship henceforth is governed solely by currently operative agreements. 09957.00000\45068479.1 2 22852671.14 The Parties therefore agree as follows: 1. Identification of Defunct Prior Agreements. The Parties acknowledge that the Defunct Agreements listed in Exhibit A were entered into in connection with various aspects of the Parties’ historical relationship. 2. No Continuing Effect. The Parties hereby confirm that each of the Defunct Agreements is no longer in effect and has no continuing legal force or effect, as of the Effective Date. 3. No Amendment; Termination of Survival Provisions. This Agreement pertains only to the Defunct Agreements and no other agreements. Any and all provisions of the agreements identified in Exhibit A, including any Survival Provisions between the Parties that might otherwise be deemed to survive full performance, expiration, supersession, or termination of a Defunct Agreement, are hereby terminated, extinguished, and of no further force or effect, as of the Effective Date. 4. No Waiver or Release. Nothing in this Agreement constitutes a waiver, release, or discharge of any rights, obligations, or liabilities of either Party under any agreement other than the Defunct Agreements. 5. Attorneys’ Fees. If any Party brings any legal action to interpret or enforce any provision of this Agreement, then the prevailing Party in that action will be entitled to receive, in addition to all other available relief, costs of litigation and reasonable attorneys’ fees, including expert witness fees, costs and fees incurred on appeal and in enforcing any judgment which may be rendered on the underlying action. 6. No Third Party Beneficiaries. The Parties expressly acknowledge and agree that they do not intend, by their execution of this Agreement, to benefit any person or entities not signatory to this Agreement. No person or entity not a signatory to this Agreement will have any rights or causes of action against IRWD or OC San or any combination thereof, arising out of that Party’s entry into this Agreement. 7. Governing Law. This Agreement will be interpreted and enforced in accordance with the provisions of California law, without regard to conflicts of law provisions. 8. Notice. Unless otherwise permitted by this Agreement, all notices to be given must be in writing and may be made by personal delivery or overnight delivery by nationally recognized carrier with a c.c. by email. Notices sent by overnight delivery must be addressed to the Parties at the addresses listed below, but each Party may change the address by written notice in accordance with this paragraph. Receipt will be deemed made as follows: notices delivered personally will be deemed communicated as of actual receipt; mailed notices will be deemed communicated on receipt or rejection. 09957.00000\45068479.1 3 22852671.14 If to IRWD: Irvine Ranch Water District 15600 Sand Canyon Avenue P.O.
