Element 6 – Spill Emergency Response Plan City of Pleasanton Sewer System Management Plan, July 2025 25 and collect information for prevention of future spills. A “spill or SSO” is defined by State Water Board Order No. WQ 2022-0103-DWQ as a discharge of sewage from any portion of a sanitary sewer system due to a sanitary sewer system overflow, operational failure, and/or infrastructure failure. The City’s employees are required to report all spills from City owned sewer mains and laterals and to take the appropriate action to secure the spill area, properly report to the appropriate regulatory agencies, relieve the cause of the spill, and ensure that the affected area is cleaned as soon as possible to minimize health hazards to the public and protect the environment. The City’s goal is to respond to sewer system spills as soon as possible following notification. The City will follow reporting procedures regarding sewer spills as set forth by the San Francisco RWQCB and the SWRCB Order No. WQ 2022-0103-DWQ (SSSWDR). The SERP provides guidelines for City personnel to follow in responding to, cleaning up, reporting, and properly documenting spills that may occur within the City’s service area. Additionally, the SERP outlines procedures for responding to sanitary sewer spill backups into structures as required by the City’s insurer. “Backup” is a term typically used by insurers to describe property damage resulting from exposure and contact to untreated or partially treated sewage. The link to the Spill Emergency Response Plan document is included in Section 6.2. The SERP includes a narrative of the plan, Sewer Spill/Backup Response Workbook that contains all documents used to properly document the City’s response activities to all spill events, and procedures for water quality monitoring when applicable. 6.2: References • WDR Attachment D – Section 6 • City of Pleasanton Spill Emergency Response Plan
