Stormwater Pollution Planning and Preparation SWPPP

Industrial stormwater discharge regulatory compliance defined by the National Pollutant Discharge Elimination System – NPDES, and the Federal Multi-Sector General Permit – MSGP, slated for implementation in January 2021, will affect state Industrial General Permits. In the states where the EPA is the regulating body (New Mexico, New Hampshire, and West Virginia), the impact will be immediate.

California on the Rise, by Jonathan Meronek and Alissa Barrow, discusses the emerging general commonalties of “lessons learned” that can help dischargers successfully manage their stormwater programs.

Jonathan and Alissa explain best practices that help businesses understand and prepare ahead of the expected changes. The strategies can streamline preparation and response to minimize risk and help prevent fines and lawsuits.

The State Water Resources Control Board (SWRCB)’s industrial stormwater website has developed many new guides to help industrial dischargers (Industrial General Permit, IGP, permitees) understand what is required  and how to best to utilize the on-line reporting protocols for IGP compliance.  Despite the resources and this outreach provided on the SWRCB website many industries and businesses could be at risk, and may not understand that they could be in violation of the current IGP.


Recent direct communications with SWRCB and local Regional Boards’ have indicated that during the 2016-2017 permit cycle year, inspections will be more detailed for facilities considered to be at high risk, which were specifically named as those with a long history of water quality violations, as well as scrap metal recyclers, and End-of-Life Vehicle (ELV) recycling. There will also be increased focus on facilities that discharge to impaired waterbodies with adopted Total Maximum Daily Load (TMDL) requirements.


Industries should take action now if there is any uncertainty in regards to the meeting permit regulations.  Contact your local SCS Engineers’ office or one of our industrial stormwater experts in California, Cory Jones or Jonathan Meronek.  If you need questions answered, or if you are unsure of your business’s requirements, and believe that your facility may be in violation, SCS will help sort through the permitting red-tape. This includes SMARTs filing, NOI/NEC or NONA submittals, SWPPPs and Monitoring and Implementation Plans.
