Discharge & Regulatory Permits
Wastewater Discharge Permit
Regulatory Background
Regional San, along with all wastewater treatment agencies, is regulated by the state and federal government under a strict set of laws generally established under the Federal Clean Water Act (CWA) passed in 1972. Important amendments to the CWA were added in 1977 that further regulate wastewater treatment.
Sewer System Management Plan (SSMP)
Regional San is required to comply with the State Water Resources Control Board Order No. 2006-0003, Statewide General Waste Discharge Requirements (WDR) for Sanitary Sewer Systems. The purpose of the Order is to require agencies to prepare a plan and schedule for measures to be implemented to reduce Sanitary Sewer Overflows (SSOs), as well as measures to effectively clean-up and report SSOs.
