Issues for Discussion 

April 9, 2021 

EPA’s Final 2021 Multi-Sector General Permit (MSGP) 

The Environmental Protection Agency (EPA) recently published its final 2021 Multi-Sector General Permit (MSGP) under the Clean Water Act (CWA). Under the CWA, EPA is authorized to issue a National Pollutant Discharge Elimination System (NPDES) permit for the discharge of any pollutant into a water of the United States from a point source. EPA is further authorized under the CWA to establish permit application requirements for stormwater discharges associated with industrial activity using a phased approach. As a result of such authorization, EPA has issued the MSGP for industrial stormwater discharge at least every five years beginning in 1995. The MSGP contains provisions requiring industrial facilities to implement control measures and develop site-specific stormwater pollution prevention plans (SWPPPs) to comply with the NPDES program. 

On January 15, 2021, EPA issued the 2021 MSGP which replaces the 2015 MSGP. The 2021 MSGP has significant modifications from the 2015 MSGP, including the requirement for permittees not otherwise obligated to adhere to certain benchmark monitoring requirements to collect data on pH, TSS, and COD. In addition, the 2021 MSGP has developed modified Additional Implementation Measures (AIM) requirements to address benchmark exceedances. The 2021 MSGP will expire on February 28, 2026, and EPA is expected to issue a new MSGP before this time. 

At this roundtable, EPA will be providing an overview of the 2021 MSGP, including modifications made from the 2015 MSGP. Jeffrey Longsworth is a Partner as Barnes & Thornburg LLP as well as the Coordinator for the Federal StormWater Association, which represents the interests of several small business members. Mr. Longsworth will be providing comments on the impact of the changes in the 2021 MSGP on small businesses. Time will be available for discussion and questions directed to both EPA and Mr. Longsworth.
