Overview of Provision C.3 of Municipal Regional Stormwater Permit (MRP) (PDF)

On October 14, 2009, the Bay Regional Water Quality Control Board (SFRWQCB), San Francisco Bay Region, issued a municipal regional stormwater permit (MRP) under the National Pollutant Discharge Elimination System (NPDES) permit program to the Alameda Countywide Clean Water Program (ACCWP). The goal of the MRP is to reduce pollution in stormwater runoff and limit increases in runoff flows from development projects. The City of Oakland, as a member of ACCWP, is a co-permittee under ACCWP’s permit and is, therefore, subject to the MRP requirements.

The SFRWQCB reissued MRP 3.0. The MRP 3.0 went into effect July 1, 2022, with further changes to the Regulated Project Thresholds effective July 1, 2023.
