USEPA Proposes Modifications to Industrial Stormwater Permit

Posted on June 02, 2020


The United States Environmental Protection Agency (USEPA) has proposed significant changes to their 2015 National Pollutant Discharge Elimination System (NPDES) Multi-Sector General Permit (MSGP). These changes, which are expected to substantially affect industrial facilities, are being incorporated into a Proposed 2020 MSGP. The Final 2020 MSGP is anticipated to be issued on November 12, 2020 based on recent communications from the USEPA.

The USEPA is the primary stormwater permitting authority for the following states and U.S. territories: Idaho (until 2021), Massachusetts, New Hampshire, New Mexico, Washington DC, American Samoa, Guam, Johnston Atoll, Midway Island, Northern Mariana Islands, Puerto Rico, and Wake Island. The USEPA has stormwater permitting authority over specific types of industry (i.e., specific oil and gas industries) or federally-operated facilities in the following states: Colorado, Delaware, Oklahoma, Texas, Vermont, and Washington. Other than those listed above, state regulatory agencies are the primary stormwater permitting authorities and are not required to implement the changes included in the Proposed 2020 MSGP; however, over half of the states with primary stormwater permitting authority currently have identical or somewhat similar stormwater permit requirements to the Proposed 2020 MSGP.
