Operation and Maintenance
Stormwater treatment and hydromodification management measures are not effective if they are not properly operated and maintained. The Program’s NPDES permit requires each Co-permittee to implement a stormwater treatment BMP Operation and Maintenance (O&M) Verification Program, to ensure that property owners are maintaining BMPs installed on their sites. To assist Co-permittees, Program staff has developed O&M verification guidance documents; provided support to Co-permittees in setting up verification programs, conducted training workshops on O&M verification; and developed a standardized approach for collecting and reporting inspection data. Currently, Co-permittees are implementing O&M verification programs conducting inspections, and reporting the results in their annual reports to the Regional Water Quality Control Board.
