The regulation of stormwater at industrial facilities in California is about to undergo a dramatic change, as the next General Permit is expected to be adopted by the State Water Resources Control Board (State Water Board) during the summer of 2013, with a likely effective date of January 1, 2015. The State of California has regulated stormwater discharges from industrial facilities in California since 1991, and the current General Permit has been in place since 1997. Integral Consulting Inc. is closely following developments related to the adoption of the State Water Board’s draft General Permit for Discharges of Stormwater Associated with Industrial Activities.


Because the numerous proposed changes could significantly impact industrial dischargers, it is important for dischargers to know what is contained in the upcoming regulations, how the changes will affect their operations, and the potential ramifications of not meeting the numeric action levels. Fortunately, it is not too late to provide comments on the permitting process. After the next draft permit is released, the State Water Board will allow another public comment period before final adoption.
