Storm Water Permitting

The Clean Water Act is a federal piece of legislation adopted in 1972 with the objective of restoring and maintaining the integrity of the nation’s waters.  Under the Clean Water Act discharges of pollutant-containing storm water must be regulated by issued permits.

New Storm Water Industrial PermitCalifornia governs and maintains compliance with the Clean Water Act by issuing a specific state-wide storm water permit commonly referred to as the Industrial General Permit which covers all industrial facilities subject to the storm water program within California.  California storm water program applicability is determined based on a business’s SIC code.  A complete listing of California industry categories subject to the Industrial General Permit can be found by clicking on the following link below.

Storm Water Program Applicability by Industry

The Industrial General Permit contains many requirements for facilities to comply with including, but not limited to

  • Electronic reporting and filing
  • Best Management Practices (BMPs) for preventing storm water pollution
  • Development of a Storm Water Pollution Prevention Plan (SWPPP)
  • Storm water sampling, and development of a monitoring plan

In addition, the Industrial General Permit includes training requirements in the form of Qualified Industrial Storm Water Practitioner (QISP) certification. QISPs are people trained in storm water regulations and registered through the California State Water Board. The Industrial General Permit mandates that many requirements be completed by a QISP.
