GM Monthly Report - June 2026
June 17, 2026 TO: Chair and Members of the Board of Directors FROM: Robert C. Thompson General Manager SUBJECT: June Status Report The following status report is submitted for your review and consideration. 1. Public and Environmental Health Since November 2022, OC San has successfully maintained 388 miles of regional sewer pipes and 15 pump stations with zero sewer spills by performing routine maintenance, replacing aging pipes, and conducting internal audits of the Sewer System Management Plan through a coordinated effort from Operations & Maintenance, Engineering, and Environmental Services Departments. For reference, the State of California spill rate is 3.19 spills per 100 miles per year, and for Santa Ana Region 8 the spill rate is 1.11 spills per 100 miles per year. 2. Sound Finances and Increasing Efficiency Two-Year Budget Preparation Concluding Budget preparation for Fiscal Years 2026-27 and 2027-28 is complete. Revenue, debt service, capital outlay, insurance, and operating expenses have been submitted, discussed, and included in the proposed budgets. Staff presented a summary of the proposed budgets at the June Committee meetings. The full Board is voting on the budgets at the June 24th meeting for Fiscal Year 2026-27 of $673.2 million and Fiscal Year 2027-28 of $706.4 million. 3. Recovering Valuable Resources Supercritical Water Oxidation (SCWO) Contract Modification and New Schedule The SCWO contract will be modified, reducing the throughput of the system from six tons to 3.25 tons per day. This will allow OC San to accept recent runs of factory testing and receive the system once final equipment and site prep modifications are complete. Chair and Members of the Board of Directors June 17, 2026 Page 2 of 4 4. Community Outreach and Transparency Engaging with our Public This month, OC San hosted eight tours, including groups from the Yorba Linda Water District, cities of Anaheim, Irvine, and Tustin, Clean Water SoCal, and a team from Future Path Leaders. Staff welcomed the Regional Water Board for an annual inspection, and I gave a presentation at the California Association of Sanitation Agencies Partnering for Impact meeting. Staff hosted a construction outreach event in the City of Cypress for the Cypress Truck Sewer project; and gave a presentation at the National Association of Clean Water Agencies Strategic Communications Conference on our Wastewater 101 Citizens’ Academy. Library Program Kicks Off OC San launched our Below and Beyond Library Program, a new outreach initiative that introduces children and teens to the important work of wastewater professionals through a story time or career exploration workshop, paired with a hands-on activity. Our first session takes place on June 25 at the Anaheim Hills Library, with an additional program planned in a second Anaheim library in July and in the City of Orange in September. OC San Connection Newsletter – Summer Issue The summer issue of the OC San Connection Newsletter will be published later this month. It will be distributed to more than 3,500 email subscribers and through OC San’s social media channels and website. The newsletter will feature updates on the Taft Avenue Sewer Improvement Project, the Bay Bridge Pump Station Project, educational content focused on Fats, Oil and Grease (FOG) disposal during Fourth of July celebrations and much more to engage readers of all ages. 5. Legislative and Industry Affairs Legislative Update • Federal The House Appropriations Committee advanced its Fiscal Year 2027 Interior and Environment spending bill, preserving funding for the State Revolving Fund and Water Infrastructure Finance and Innovation Act programs and rejecting proposed cuts. The committee also directed the U.S. Environmental Protection Agency to promptly distribute previously awarded community project grants. Meanwhile, Representative Scott Peters (D-California) continues developing legislation to address liability protections for passive receivers of per- and polyfluoroalkyl substances, with introduction possible later this year. Chair and Members of the Board of Directors June 17, 2026 Page 3 of 4 • State With the June 2 Primary Election now complete, attention has turned to the November General Election. The primary narrowed the field of candidates and set up a gubernatorial race between Steve Hilton and Xavier Becerra. At the Capitol, activity has slowed following the House of Origin deadline, as Assembly and Senate committees begin reviewing bills passed by the other chamber. • Local Following the Memorial Day weekend evacuation of more than 50,000 residents due to a potential chemical plant explosion in Garden Grove, GKN Aerospace donated $3 million to Orange County United Way’s Community Resilience Fund to support impacted families and businesses. Plans are underway to safely remove and dispose of the chemical methyl methacrylate. Meanwhile, local officials and residents are seeking answers about the facility’s past violations and its future. OC San is providing its permit enforcement documentation dating back to 2016 to federal, state and local oversight agencies OC San Receives Recognition • NACWA Peak Performance Award The National Association of Clean Water Agencies recognized OC San with the Platinum Peak Performance Award for Plant Nos. 1 and 2. The Platinum award recognizes 100 percent compliance with permits over a consecutive five-year period. This is OC San's 13th consecutive year win. • Graphic Design USA OC San received two awards from the Graphic Design USA - In-House Awards. Of the 4,000+ entries, OC San was in the top ten percent and was recognized for: • OC San Annual Report • Santa Ana Trunk Sewer Rehab Movie Poster • Project Portfolio Management Web OC San received the Public Sector Leadership Award from PMWeb for delivering critical public infrastructure with control and accountability. OC San Featured in Municipal Water Leader Magazine OC San’s award-winning Wastewater 101 Citizens’ Academy was highlighted in the June issue of Municipal Water Leader Magazine (Page 21). The article highlights the successful program and the importance of programs like this in the industry. Chair and Members of the Board of Directors June 17, 2026 Page 4 of 4 6. Workforce and Administration GM Work Plan Year-End Report As we conclude the 2025-26 fiscal year, I can report that nineteen of the 21 goals in my Work Plan are complete. One goal related to the Pretreatment Information Management System will continue into the next fiscal year. The Supercritical Water Oxidization goal will be removed from the GM Work Plan based on the progress achieved to date and the successful advancement of the technology. Centralized Training Year-End Report OC San’s training and development programs continue to support a highly skilled workforce. In Fiscal Year 2025-26, OC San again exceeded its Level of Service commitment, surpassing the goal of 40 training hours per employee. Training topics included emergency preparedness, cybersecurity awareness, workplace safety and threat response, leadership academy, presentation skills, and artificial intelligence tools. A couple of training programs were also made available to member agency staff, supporting regional workforce development and collaboration. OC San continued its partnership with California State University, Fullerton’s Leadership for Public Agencies program, bringing the total number of program graduates to 74 since 2010. OC San also collaborated with local educational institutions and industry partners to align educational programs with recruitment needs for critical and hard-to-fill positions. As part of its workforce development strategy, OC San hosted wastewater operator certification test preparation courses for employees and the public, supporting employee advancement while helping attract qualified candidates. Individual Development Plans, implemented agencywide in Fiscal Year 2025–26, remain on track and are now a permanent component of employee development.
