Home My WebLink AboutGM Monthly Report - May 2025r U MEMORANDUM . ORANGE COUNTY SANITATION DISTRICT May 28, 2025 TO: Chair and Members of the Board of Directors FROM: Robert C. Thompson <�CJ General Manager SUBJECT: May Status Report The following status report is submitted for your review and consideration. 1. Public and Environmental Health Safety and Security Update I wish to follow up on the incident that occurred last week at our HQ front entrance, where a firearm was discharged by a contracted Allied Universal security guard. This was an isolated incident. Two contracted guards involved in the incident were terminated and are prohibited from entry at all OC San facilities. Both OC San and Allied Universal continue to cooperate with the Fountain Valley Police Department who have filed charges in connection with the incident. Obviously, this is not an acceptable outcome for OC San or Allied Universal. Both OC San and Allied Universal are reviewing the incident and are committed to implementing lessons learned to improve the security of OC San staff and facilities. Improvements to training, procedures, and post orders will follow the lessons learned process. The day following the incident, I personally met with the Allied Universal leadership team and was assured that a full investigation would be conducted, and their findings and corrective actions would be promptly communicated to us. Allied was recently awarded the contract through a competitive process based on their qualifications. While two individuals did not live up to the service expectations of OC San or Allied Universal, we remain confident in Allied Universal's ability to meet our service needs. Employee safety is our top priority. We live in a complex world with people displaying extreme and unpredictable behavior, as well as criminal activity, all around. OC San remains committed to ensuring we have proactive physical security measures in place to protect employees and our critical infrastructure. New Traffic Signal on Ellis Avenue A new traffic signal is being installed at the intersection of Ellis Avenue and Mt. Langley Street to provide a protected left turn onto Ellis Avenue for staff and guests Chair and Members of the Board of Directors May 28, 2025 Page 2 of 4 leaving Headquarters and for the future lab building on Mt. Langley Street. The traffic signal will also add pedestrian crosswalks. Construction is expected to be completed by this summer. Once constructed, we will transfer ownership of the signal to the City of Fountain Valley. Engine Backfire at Plant No. 2 Under Investigation On Friday April 25, 2025, the contractor for the Engine and Generator Overhauls Project No. J-135B, Cooper Machinery Services LLC (Cooper), was performing a 96-hour test run at Plant No. 2 CenGen Engine 5. During the test, the engine backfired and caused damage to the exhaust piping and exhaust piping supports. OC San is in the process of investigating the cause of the incident and the extent of the damage. OC San and Cooper will develop a recovery plan to repair the damaged components. Based on an initial assessment, the engine does not appear to be damaged. The Purchasing team is currently coordinating with both Legal and Risk to work through the respective contractual and insurance processes. Introducing the RISE Program For over 70 years, OC San has been leading the way in wastewater treatment and management, pioneering innovative technologies and approaches to improve our services and protect the environment. We're now excited to launch our new program, Resource Innovation for a Sustainable Environment (RISE). This program captures many of the efforts previously undertaken by OC San, currently underway, and new initiatives such as Supercritical Water Oxidation and Deep Well Injection. Explore www.ocsan.gov/RISE to see how we're implementing transformative technologies and initiatives. By continuing to invest in innovative processes and equipment, we're improving operations in water, energy, solids, and air management, ensuring a cleaner, more resilient future for our community. 2. Sound Finances and Increasing Efficiency Two -Year Budget Preparation Update OC San adopted its biennial budget for FY 2024-25 and FY 2025-26 in June of 2024. It is now time to update the second -year budget for FY 2025-26 to account for any changes and needed adjustments. The Financial Management team has worked with all the departments to update their budgets and requests. The Engineering and Finance teams have finalized validation of the Capital Improvement Program (CIP). The Committees will receive presentations of the completed budget, and it will go to the Board for adoption at the June meetings. 3. Recovering Valuable Resources GWRS — Flow Provided by OC San Following the completion of repairs at Plant No. 1 Sunflower Pump Station, Plant No. 2 resumed operations in "separated" mode. This operational configuration allows the Orange County Water District (OCWD) to recover valuable resources by utilizing the reclaimable flows generated by Plant No. 2. From January through Chair and Members of the Board of Directors May 28, 2025 Page 3 of 4 March of this year, OC San supplied OCWD with an average of 173 million gallons per day to support our joint water reclamation efforts. 4. Community Outreach and Transparency Engaging with our Public (Tours and Presentations) OC San participated in 11 tours this month reaching students from Orange Coast College, University of California, Irvine, and Servite High School. Staff also gave tours to the Fountain Valley Chamber of Commerce, California Water Environmental Agency, OC San Director Leon and his staff, our Ocean Monitoring team, a general public tour, and the South Coast Air Quality Management group. Staff also participated in a Career Day at Curtis Middle School. Overall, we reached over 200 people. OC San Featured in the OC Register's Special Water Insert Once again, OC San is part of the Orange County Register's California Water Supplemental Educational online insert - a piece featuring OC San and several other local agencies. The article highlights our newly launched Resource Innovation for a Sustainable Environment (RISE) program which covers our innovative and cutting - edge efforts such as Supercritical Water Oxidation Project and Deep Well Injection. The insert is now published and available at www.ocsan.gov and via our social media channels. 5. Legislative and Industry Affairs State Update The rapid pace of legislative activity in April is expected to continue through May and June, as lawmakers work toward several upcoming deadlines. May 2 was the deadline for policy committees to hear and report fiscal bills to fiscal committees. Just one week later, on May 9, policy committees were to report non -fiscal bills to the Floor. By May 23, fiscal committees are required to complete their hearings and report all bills to the Floor in their respective House of origin. Federal Update The United States Environmental Protection Agency Administrator, Lee Zeldin, issued his core principles for per- and polyfluoroalkyl substances (PFAS). Among his priorities are: 1) passive receivers liability protection, 2) expeditious finalization of Risk Assessment Model for Biosolids based upon public comments, 3) effluent guidelines for manufacturers and users of PFAS, and 4) increased commitment to update PFAS destruction guidance for utilities annually. OC San is actively monitoring the various PFAS efforts and understanding the potential impacts to our current and future operations. Senate Bill (SB) 496 (Hurtado) Advanced Clean Fleets On May 7, OC San submitted a letter of support for SB 496. This bill if passed, would create an Advanced Clean Fleets Appeals Advisory Committee, to ensure disaster Chair and Members of the Board of Directors May 28, 2025 Page 4 of 4 service workers are able to effectively respond to emergency situations, and provide needed and common-sense reforms for compliance. OC San Wins GFOA Award For the 31 st consecutive year, OC San has earned the Certificate of Achievement for Excellence in Financial Reporting from the Government Finance Officers Association (GFOA). This prestigious award recognizes OC San's comprehensive financial report for the fiscal year, which ended June 30, 2024, and reflects the agency's ongoing commitment to transparency, accountability, and excellence in financial reporting. 6. Workforce and Administration Strategic Planning Process As part of the Strategic Planning process, all current policy areas have been presented to the Board as well as OC San's Core Values. In the coming months, the Levels of Service and the Risk Register will be presented to the Operations and Administration Committees. During this time, the plan will be updated based on feedback received with a draft plan presented to the Board in September, and the final in November.
