The Industrial General Permit (IGP) regulates industrial stormwater discharges and authorized non-stormwater discharges from industrial facilities in California. The Industrial General Permit is called a general permit because many industrial facilities are covered by the same permit, but comply with its requirements at their individual industrial facilities. The State Water Resources Control Board (State Water Board) and Regional Water Quality Control Boards (collectively, the Water Boards) implement and enforce the Industrial General Permit.
Attachment A of the permit includes a complete list of facilities covered by the Industrial General Permit.
The City of West Sacramento is required to track all facilities within the City that require IGP coverage. New business licenses are reviewed for potential coverage requirements and referred to the Board if they do not provide proof of coverage (or non-applicability, as described below). Read below for how to demonstrate compliance to the City.
New businesses with SIC codes that require coverage may provide their permit information by contacting the Environmental Services Department at (916) 617-4590. Please provide one of the following:
- Proof of coverage
- Proof of NEC
- Approved NONA
- Proof of submitting for any of the above
- Or, other evidence that coverage is not required (such as communication with the Board)
