Title
Approve the CSA75 Chualar Consolidated (CSA75) Sewer System Management Plan (SSMP) dated June 2024 and the Sanitary Sewer Spill Emergency Response Plan (SERP) dated November 2023.
Report
RECOMMENDATION:
It is recommended that the Board of Supervisors approve the CSA75 SSMP dated June 2024 and the CSA75 SERP dated November 2023.
SUMMARY:
The State Water Resources Control Board’s (SWRCB) Statewide Waste Discharge Requirements General Order for Sanitary Sewer Systems, Order WQ 2022-0103-DWQ, mandates that enrollees develop and maintain a SSMP and SERP. These documents provide a plan and schedule to properly manage, operate and maintain all parts of the sanitary sewer system to help reduce and prevent sanitary sewer spills and mitigate any spills that do occur.
DISCUSSION:
The CSA75 SSMP (Attachment A) and CSA75 SERP (Attachment B) were developed in compliance with SWRCB Order WQ 2022-0103-DWQ. The SSMP consists of the following 11 elements:
1. Goals
2. Organization
3. Legal Authority
4. Operation and Maintenance Program
5. Design and Performance Provisions
6. Spill Emergency Response Plan
7. Sewer Pipe Blockage Control Program
8. System Evaluation, Capacity Assurance Plan & Capital Improvements
9. Monitoring, Measurement, and Program Modifications
10. Sewer System Management Plan Program Audits
11. Communication Program
Element 6 of the SSMP summarizes the SERP; however, the SERP is maintained as a separate document with spill response details to help facilitate a rapid and effective response. The SERP must be reviewed and assessed annually and updated as appropriate.
OTHER AGENCY INVOLVEMENT:
On August 11, 2023, the Regional Water Quality Control Board issued a Notice of Violation requiring CSA75 to immediately implement corrective actions to bring the collection system into compliance with WDR Order No. 2022-0103-DWQ. The corrective actions included developing and maintaining a SSMP and SERP.
FINANCING:
On September 19, 2023, the Board of Supervisors adopted a resolution to provide a one-time appropriation of $250,000 from the FY2023-24 General Fund contingency which included $82,500 to fund preparation of the CSA75 SSMP and SERP. Approving the reports will have no impact to the General Fund. However, follow-up actions required by the SSMP, or SWRCB mandates, will be funded by CSA75.
BOARD OF SUPERVISORS STRATEGIC INITIATIVES:
If approved, this action supports the Board of Supervisors’ Strategic Initiatives for Administration and Infrastructure. The Project will provide sustainable physical infrastructure and promotes the safety of residents and visitors.
