GM Monthly Report - March 2026
March 18, 2026 TO: Chair and Members of the Board of Directors FROM: Robert C. Thompson General Manager SUBJECT: March Status Report The following status report is submitted for your review and consideration. 1. Public and Environmental Health Recap of Rainy Season During the 2025–2026 winter season, OC San has thus far managed six storm events, totaling approximately 11 inches of rainfall. The highest instantaneous influent peak flows occurred in late December, reaching about 222 million gallons per day (MGD) at Plant No. 1 and 206 MGD at Plant No. 2, compared to typical dry weather peaks of 163 MGD and 93 MGD, respectively. Staff responded promptly, and no major incidents occurred. While forecasts indicate dry conditions for the remainder of the season, OC San remains prepared to respond to additional storm events if needed. 2. Sound Finances and Increasing Efficiency Budget Preparation Continues Budget preparation for Fiscal Years 2026-27 and 2027-28 is well underway. Items being submitted for consideration include training, conferences, memberships, personnel, capital outlay, and operating expenses. Engineering and Finance staff are validating the Capital Improvement Program for the upcoming budget. Staff will provide a presentation on operating expenditures at the April Committee meetings. Easement Assessment Update (One year update) In support of the GM Work Plan goal to conduct surveys of properties with identified encroachments or access limitations to OC San’s property rights by June 30, 2026, staff are conducting a comprehensive review to identify all OC San easements throughout Orange County. Member agencies have been notified of this effort, and easement maps will be shared upon completion. Phase One is approximately 85 percent complete, with 744 land records reviewed and approximately 172 remaining. Completion is expected by June 2026. Staff have also Chair and Members of the Board of Directors March 18, 2026 Page 2 of 4 begun surveying properties to identify potential encroachments and are coordinating internally to manage updated easement records and prioritize future survey areas. 3. Recovering Valuable Resources South Orange County Biosolids Workshop Examines Future Biosolids Management I participated in a regional biosolids workshop hosted by the South Orange County Wastewater Authority on February 25 at the JB Latham Wastewater Treatment Plant in Dana Point. The workshop brought together member agencies, regional partners, and technology providers to discuss biosolids management challenges in Southern California and emerging technology options. The discussion also provided an opportunity to share OC San’s ongoing biosolids research efforts and explore potential regional collaboration on future management strategies. 4. Community Outreach and Transparency Engaging with our Public This month, OC San hosted 18 tour groups, including students from Cal State Long Beach, Cal State Fullerton, Huntington Beach High School, Canyon High School, Orange Coast College, Estancia High School and members of the general public reaching over 360 participants. Staff also participated in a Career Day at Cerro Villa Middle School, served as judges for the Orange County Science and Engineering Fair, and participated on a Construction Network panel discussing wastewater projects and contracting opportunities. Wastewater 101 Citizens’ Academy Graduation OC San has concluded the sixth session of Wastewater 101 Citizens’ Academy, with an average of 55 attendees per each class. Participants who successfully completed all four classes will graduate at the March 25 Board meeting. It is anticipated that this winter cohort will have more than 40 graduates. Participants learn about the wastewater treatment process, OC San’s infrastructure and operations, and the agency’s role in protecting public health and the environment. The next session is scheduled for winter 2027. 5. Legislative and Industry Affairs Legislative Update • Federal Legal challenges to the U.S. Environmental Protection Agency (USEPA) drinking water standards for Per- and Polyfluoroalkyl Substances (PFAS) are Chair and Members of the Board of Directors March 18, 2026 Page 3 of 4 ongoing. The American Water Works Association and the Association of Metropolitan Water Agencies have filed petitions opposing the USEPA’s request to separate six PFAS standards from the broader lawsuit challenging the entire rule. If the court agrees, the full legal challenge will continue. A congressional briefing on PFAS contamination and passive receivers is scheduled for the week of March 23. • State The deadline to introduce new legislation was last month, bringing the total number of bills to more than 1,800, including about 600 placeholder “spot” bills. As these bills are amended with policy details and meet the 30-day public review requirement, policy committee hearings are expected to increase in late March. Separately, Governor Gavin Newsom released the California Water Plan 2028, outlining a long-term strategy to improve water reliability. The plan sets a goal of generating nine million acre-feet of new water supply by 2040 through expanded storage, conservation, recycling, and groundwater recharge. • Local The County's Frank R. Bowerman Landfill in Irvine has been cited recently by South Coast Air Quality Management District (SCAQMD) inspectors for odors from the facility. SCAQMD issued three Notices of Violation to Orange County Waste and Recycling in early February after receiving dozens of odor complaints from surrounding communities in the month prior. Elsewhere, the Orange County Board of Supervisors approved a portion of the proposed Climate Action Plan (CAP) Implementation document at its February 24 meeting but carried over one section of the CAP for further discussion at its meeting which was discussed at the March 10 meeting. OC San Receives Recognition OC San was awarded the 2026 WateReuse Award for Excellence in Outreach and Education for Wastewater 101 Citizens’ Academy. This award recognizes significant success in advancing public acceptance of recycled water. 6. Workforce and Administration Leadership Academy Training for Management This organization-wide leadership development initiative includes 23 executives and managers and will run through late April. As of this month, five of the seven sessions have been completed. The program is designed to strengthen leadership capabilities and provide practical tools needed to lead effectively in today’s dynamic workplace Chair and Members of the Board of Directors March 18, 2026 Page 4 of 4 environment. Core learning objectives focus on governance, self-awareness, team leadership, coaching and development, conflict resolution, and strategic influence. These objectives are reinforced through assessments and individualized coaching. All participants received one-on-one coaching focused on identifying personal strengths and opportunities for growth, helping leaders build greater self-awareness and enhance their effectiveness. Executives also received additional coaching informed by a 360-degree assessment incorporating feedback from supervisors, peers, and direct reports. Leadership development supports strategic alignment, organizational performance, and employee retention. OC San Retirements and Recruitment On February 18, 2026, OCERS announced a three percent Cost of Living Adjustment for members who retire on or before April 1, 2026. To date, OC San has confirmed a total of seven retirements for the period of January through March 2026, representing a total of 112 years of service. By comparison, 16 employees retired during the same period in 2025, indicating a lower retirement rate this year. Human Resources continues to focus on filling vacancies quickly and effectively, while also proactively planning for anticipated openings resulting from upcoming retirements and the implementation of the Engineering Department Staffing Plan. OC San’s current vacancy rate is 4.93 percent, and a total of 67 positions have been filled to date in Fiscal Year 2025–26.
