TITLE: Mountain View Sanitary Sewer
Management Plan Update
RECOMMENDATION
Approve updates to the City of Mountain View Sanitary Sewer Management Plan as required by the State Water Resources Control Board.
BACKGROUND
The Public Works Department maintains and operates the City of Mountain View (City) sanitary sewer system and maintains records of sanitary sewer spills. To provide a consistent, statewide regulatory approach to address sanitary sewer spills, the State Water Resources Control Board (Water Board) adopted Statewide General Waste Discharge Requirements for Sanitary Sewer Systems, Water Quality Order No. 2022-0103-DWQ (Sanitary Sewer Systems General Order), on December 6, 2022. Among other requirements, the Sanitary Sewer Systems General Order requires public agencies that own or operate sanitary sewer systems greater than one mile in length to develop and implement sewer system management plans (SSMP s). SSMPs establish the methods and programs to meet certain goals pertaining to the effective operation of sewer collection systems, including:
• Properly manage, operate, and maintain all parts of the sewer system; • Reduce and prevent spills; and
• Contain and mitigate spills that do occur.
The Public Works Department prepared , and City Council approved , the City’s original SSMP in 2008. It has been updated periodically to reflect organization changes, collection system master plan updates, changes in regulatory requirements, and other relevant changes with the last major update in 2018
.
ANALYSIS
The Water Board’s 2022 Sanitary Sewer Systems General Order included regulatory requirement updates. These include updated sanitary sewer spill category classifications, new requirements

for Legally Responsible Officials, revised timelines for SSMP updates and audits, and more prescriptive sewer system evaluation and capital improvement implementation plans. However, most of the changed requirements are attributed to reporting requirements and regulatory deadlines, which are already reflected in the City’s current wastewater programs and operations.
The updated 2025 SSMP addresses the regulatory elements from the Water Board 2022 Sanitary Sewer Systems General Order. The most significant update to the SSMP is the reorganization of the report to address the new guidelines (see Attachment 1 for the SSMP Update).
FISCAL IMPACT
There is no fiscal impact associated with the recommended action. The City’s wastewater system maintenance activities and projects are fully funded in the Public Works Department’s operating budget and the City’s Capital Improvement Program through Wastewater Funds and Wastewater Capacity Fees.
