Industrial Storm Water 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.

Total Maximum Daily Loads
- Industrial General Permit Total Maximum Daily Load (TMDL)
State Water Board staff is developing an amendment to the Statewide Industrial General Permit, 2014-0057-DWQ (IGP) for the State Water Board's to incorporation of TMDL implementation language for TMDLs listed in Attachment E of the IGP. Please go to the IGP TMDL page for more information.
- Qualified Industrial Storm Water Practitioner (QISP)
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.
