As authorized by the Clean Water Act, the National Pollutant Discharge Elimination System (NPDES) permit program of 1972 controls water pollution by regulating point sources that discharge pollutants into waters of the United States. In 1991 the Clean Water Act was revised for non-point sources.
In California, industrial and construction sites must obtain NPDES permits through the State Water Resources Control Board (SWRCB) . Visit the State Water Resource Board website for industrial or construction regulatory information.
Stormwater Pollution Prevention Plan
Development and implementation of a Stormwater Pollution Prevention Plan (SWPPP) that employs best management practices (BMPs) is a condition for obtaining NPDES permit coverage for stormwater discharges. The purpose of the SWPPP is to effectively reduce or prevent the discharge of pollutants into receiving waters. View information about SWPPPs for Construction Activities.
Industrial and Commercial Stormwater Permits
On October 14, 2009 the Regional Water Quality Control Board adopted the Municipal Regional Stormwater National Pollution Discharge Elimination System (NPDES), Permit CAS612008. This permit addresses pollutants and their impact on receiving waters.
Portion C.4.b in this permit requires the City of Richmond to have an industrial and commercial inspection plan that is significantly more detailed and requires more comprehensive industrial and commercial site controls.
The City will issue permits to industrial and commercial sites to ensure that they implement best management practices (BMPs) needed to protect water quality. View Permit FAQs.
