HomeMy WebLinkAboutGM Monthly Report - April 2026 April 15, 2026 TO: Chair and Members of the Board of Directors FROM: Robert C. Thompson General Manager SUBJECT: April Status Report The following status report is submitted for your review and consideration. 1. Public and Environmental Health Construction Begins in Santa Ana and La Palma Construction has started in two cities in our service area. The Santa Ana Trunk Project improves three miles of pipeline in the cities of Santa Ana and Costa Mesa. Construction started in the City of Santa Ana on Alton Avenue between Fairview Street and Raitt Street. The Cypress Trunk Sewer Project improves seven miles of pipeline in the cities of Cypress, Los Alamitos, and La Palma. Construction has been ongoing since last summer and has progressed into the City of La Palma where crews will upsize the sewer pipe under Denni Street. Director of Engineering Mike Dorman and the project team presented it to the City of La Palma City Council on April 7. This work will take place on Denni Street from La Palma Avenue to Denni Street Park. Work in this area is expected to begin at the end of April and last until August. 2. Sound Finances and Increasing Efficiency Budget Preparation Continues Budget preparation for Fiscal Years 2026-27 and 2027-28 is well underway. Items submitted for consideration include training, conferences, memberships, personnel, capital outlay, and operating expenses. Engineering and Finance are working on validating the Capital Improvement Program for the upcoming budget. Staff will present on the Capital Improvement Program (CIP) at the May Committee meetings. A discussion of the Insurance Program will take place at the May Administration Committee meeting as well. Chair and Members of the Board of Directors April 15, 2026 Page 2 of 4 3. Recovering Valuable Resources Supercritical Water Oxidation Update Our vendor, 374Water, Inc., has begun the 48-hours acceptance testing run. The test is intended to demonstrate contracted design capacity and continuous run endurance. Successful completion of the test is the next step to deliver the unit to OC San for long-term demonstration of the technology. 4. Community Outreach and Transparency Engaging with our Public This month, OC San hosted 12 tour groups, including students from Cal State Long Beach, Cal State Fullerton, Estancia High School, Cypress College, Santa Ana Valley High School, Rosary Academy, Fullerton College and also hosted a new employee tour, reaching more than 360 participants. Staff also participated in a speaking engagement with engineering students at Goldenwest College. Staff attended the California Water Environment Association Conference in Sacramento and also participated in the Children's Water Festival in Silverado Canyon where students in third, fourth and fifth grade learned about the importance of What 2 Flush. Community Newsletter OC San distributed the latest OC San Connection Newsletter to more than 3,600 email subscribers. This edition featured updates on key construction projects across the OC San service area, including the kickoff of a project in the City of Santa Ana, the Bay Bridge Pump Station Project, and the Cypress Trunk Sewer Project. It also included a What 2 Flush themed Easter egg hunt and additional OC San focused content to keep the community informed and engaged. Member Agency Outreach Toolkit OC San will distribute the Member Agency Outreach Toolkit in April to Public Information Officers throughout the OC San service area. The toolkit will feature ready-to-use social media posts, stories, and articles focused on summer activities, including keeping sand out of drains and protecting our beaches. It will also reinforce OC San’s “What 2 Flush” messaging, making it easy for member agencies to share timely and consistent information with their communities. Chair and Members of the Board of Directors April 15, 2026 Page 3 of 4 5. Legislative and Industry Affairs Legislative Update • State In March, the Legislature transitioned into the initial policy committee phase of the legislative session, as newly introduced legislation was assigned to policy committees. By mid- to late-month, policy committees were hearing a high volume of bills, many for the first time, as lawmakers worked to advance priority legislation. In addition, throughout the month, budget committees and subcommittees in both houses continued their review of the Governor’s proposed budget, holding hearings focused on departmental proposals, program funding, and implementation. • Federal The Senate unanimously passed the WIPPES Act (S.1092), which establishes federal "Do Not Flush" labeling requirements for non-flushable wipes modeled after California law, and sent it to the House for final passage. Though the White House has yet to submit its Fiscal Year 2027 budget request, Congress has begun the appropriations process through earmark solicitations and Member Day hearings. Finally, a congressional briefing was held to advocate for a Comprehensive Environmental Response, Compensation, and Liability Act liability exemption for passive receivers of PFAS. • Local Cities countywide continue to adopt the new landfill fees scheduled to go into effect July 1. The new rates, negotiated over the past two years as part of the Waste Infrastructure System Enhancement, or WISE, will result in monthly trash rates increasing from 12-14 percent for multi-family homes and businesses, with most single-family homes seeing their bills increase by nearly 25 percent. These new rates were adopted by OC San’s Board of Directors in March. However, an error by the County was brought to our attention following the adoption, resulting in the revised agreement coming back before the Board this month. The South Coast Air Quality Management District continues to respond to odor complaints from residents in proximity to the County's two landfills in South Orange County. OC Waste & Recycling has received nine Notices of Violation (NOVs) from inspectors responding to several hundred public complaints adjacent to Frank R. Bowerman Landfill in Irvine, and Prima Deshecha Landfill above San Juan Capistrano has been issued two NOVs. Chair and Members of the Board of Directors April 15, 2026 Page 4 of 4 OC San Receives Recognition • American Academy Environmental Engineers and Scientists OC San recently received awards for its Headquarters and Wastewater 101 Citizens' Academy in the Environmental Communications Awards category. The awards were presented on April 16 in Washington, D.C. • WoodWorks OC San's Headquarters received the 2026 Wood in Architecture Award from WoodWorks. The project was one of eight selected by an independent jury of industry peers and demonstrated high achievement in Design Excellence, Innovative Use of Wood, Sustainability & Resilience, and Market Impact. 6. Workforce and Administration Safety Quarterly Scorecard OC San’s safety performance is evaluated using various leading and lagging indicators such as training, inspections, and reporting of near misses and injuries. Through the second quarter of Fiscal Year 2025-26, OC San achieved 99.8% completion of assigned safety trainings and 100% of its office and workplace inspections. Additionally, 25% of the work groups voluntarily submitted safety observations or potential near miss reports, which are useful tools to mitigate risk and prevent an undesired outcome. Lastly, 100% of work-related injuries were reported immediately to provide prompt care and evaluation. Quarterly Performance Dashboard The Quarterly Performance Dashboard tracks progress against OC San’s Strategic Plan Levels of Service, providing a high-level overview of performance metrics that demonstrate commitment to customers, regulators, employees, and the Board. Each quarter, I include the attached report with a selection of the performance metrics.
