Permits
The Regional Board regulates point source discharge of wastewater to land and surface waters of the Region so that the highest quality and beneficial uses of these waters are protected and enhanced. Regulation is by issuance of either NPDES permits which are updated every five years, or Waste Discharge Requirements (WDRs). Each Permit contains effluent limitations which ensure the protection of the quality of the receiving waters.
If your activities or discharges from your property or business affect California’s surface waters, you will need to apply for an NPDES Permit. For discharges of wastewater to land, Waste Discharge Requirements will be issued. For specified situations, some Permits may be waived and some discharge activities can be handled through enrollment in an existing general permit.
All discharges, except residential onsite systems, are required to complete a Report of Waste Discharge (Form 200)
