Industrial Stormwater Program

The Industrial General Permit regulates industrial storm water discharges and authorized non-storm water 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.

The Statewide General Permit for Storm Water Discharges Associated with Industrial Activities, Order 2014-0057-DWQ (Industrial General Permit or IGP) implements the federally required storm water regulations in California for storm water associated with industrial activities discharging to waters of the United States. The IGP regulates discharges associated with 10 federally defined categories of industrial activities.

Industrial facilities such as manufacturers, landfills, mining, steam generating electricity, hazardous waste facilities, transportation with vehicle maintenance, larger sewage and wastewater plants, recycling facilities, and oil and gas facilities are typically required to obtain Industrial General Permit coverage. See Attachment A of the permit for a complete list of facilities covered by the Industrial General Permit.

The State Water Board is proposing an amendment to the Statewide Storm Water Industrial General Permit, Order 2014-0057-DWQ (Industrial General Permit or IGP) to incorporate: (1) implementation language for TMDLs listed in Attachment E of the IGP, (2) compliance incentives for industrial storm water capture, and (3) implementation of the recently promulgated US EPA sufficiently sensitive method requirements.

In the adoption of the IGP in 2014, the State Water Board recognized the need for a comprehensive training program to provide a statewide training specifically for individuals assisting Dischargers with compliance of this permit, standardized knowledge of implementing the Industrial General Permit through training, and required quality assurance, sampling methods, and protocols for storm water discharge sampling. Obtaining storm water discharge data that is higher in quality is crucial for future regulations in the permit.

The resources presented are intended to provide guidance on the Industrial General Permit and to provide some outreach materials on the permit for use by the public, storm water professionals and other agencies.
