Update on Federal 2021 Multi-Sector General Permit (MSGP)

On January 15, 2021, U.S. EPA finalized the Federal 2021 MSGP. The 2021 MSGP was published in the Federal Register on February 19, 2021 and became effective March 1, 2021.

The Federal 2021 MSGP applies to member facilities located only in DC, ID, MA, NH, and NM, as well as federal areas.  Member facilities in other U.S. locations are covered by industrial stormwater permits issued by their state.

Current 2015 MSGP permittees must submit their Notice of Intent (NOI) by May 30, 2021 via NeT MSGP. Prior to submitting the 2021 MSGP NOI, Stormwater Pollution Prevention Plans must be updated to meet the 2021 MSGP Part 6 requirements.

The 2021 MSGP contains several new requirements or changes relative to the 2015 MSGP. A review of these differences, including this presentation, is posted in the Stormwater section of ISRI’s Environmental Compliance page. Members-only stormwater information (e.g., Stormwater Control Manual) is available here (member log-in required).

This and other stormwater issues will be discussed at ISRI2021 in the session, Stormwater: Federal 2021 MSGP and More, on April 28 from 4:15-5:00 pm EDT. ISRI2021 registration is required.

Members seeking assistance with stormwater compliance should contact David L. Wagger, Ph.D., Chief Scientist / Director of Environmental Management at (202) 662-8533.
