National Pollutant Discharge Elimination System (NPDES) - Suction Dredge Mining
California Fish and Game Code section 5653.1, subdivision (b) has statutorily prohibited the use of vacuum or suction dredge equipment in the state since 2009. However, Senate Bill 637 which became effective on January 1, 2016 has amended section 5653 of the Fish and Game Code and added section 13172.5 of the California Water Code to provide a framework to lift the statutory prohibition on suction dredge mining.
Consistent with the requirements of Senate Bill 637, Water Board staff has solicited input from stakeholders and California Native American Tribal interests by conducting five public meetings with staff of the California Department of Fish and Wildlife in January and February 2017 in Fresno, San Bernardino, Orleans, Redding, and Sacramento prior to developing a draft statewide NPDES permit for discharges from suction dredge mining activities.

- Draft Statewide NPDES Permit Development
On May 12, 2020, the State Water Board issued a draft Statewide General National Pollutant Discharge Elimination System (NPDES) Permit to regulate discharges associated with suction dredge mining activities (in response to Senate Bill 637 (2015)). State Water Board staff held a public workshop on May 28, 2020 to explain the proposed statewide Permit. The State Water Board held a public hearing on August 5, 2020 to hear oral comments
During the State Water Board public hearing, interested parties requested that State Water Board staff provide a higher resolution map that corresponds to the proposed statewide permit for suction dredge mining activities. Consequently, the State Water Board extended the public comment period indefinitely to allow staff to develop such a map.
The State Water Board has issued a public notice announcing: (1) the availability of a draft high-resolution map, (2) two public workshops demonstrating the available mapping application, and (3) a public comment due date of March 8, 2021. Please see the Updated Public Notice below for more details. The State Water Board will consider all comments prior to consideration of the proposed General Permit.
