National Pollutant Discharge Elimination System (NPDES)
Overview
The Water Boards develop and issue general permits to cover multiple facilities within a specific category. The use of general permits allows the Water Boards to allocate resources in a more efficient manner and provide timely permit coverage for large numbers of facilities in the same category. In addition, the use of a general permit ensures consistency of permit conditions for similar facilities. According to 40 CFR section 122.28, general permits may be written to cover categories of point sources having common elements, such as:
- Storm water point sources ("Storm Water" is a separate program at the State Water Board) - see Stormwater program page
- Facilities that involve the same or substantially similar types of operations
- Facilities that discharge the same types of wastewater
- Facilities that require the same effluent limitations or operating conditions
- Facilities that require the same monitoring where tiered conditions may be used for minor differences within class (e.g., size or seasonal activity)
- Facilities that are more appropriately regulated by a general permit
However, general permits may only be issued to dischargers within a specific geographical area such as the following:
- City, County, or State boundary
- Designated planning area
- Sewer district
- Standard metropolitan statistical area
- State highway system
- Urbanized area
Additional Information
Water Board General NPDES Wastewater Permits
Below is a table that provides a list of NPDES Wastewater General Permits throughout California. It also provides a link to the program page or permit itself.
Each general permit typically includes the following information:
- How to apply for coverage under a general permit - see the" Notice of Intent" (NOI) form
- How to request rescission from coverage - see the "Notice of Termination" (NOT) form
- How to transfer ownership - some permits are not transferable so please read the permit carefully
