The Multi-Sector General Permit (MSGP) is a National Pollutant Discharge Elimination System (NPDES) permit, which stems from the Clean Water Act (CWA). The 2015 MSGP for Stormwater Discharge with Industrial Activity expired on June 3rd, 2020 and the new 2020 MSGP does not go into effect until February 12, 2021. As a result of the landmark settlement between Waterkeeper Alliance and EPA (2d Cir. 15-02091) the new MSGP brings with it several major changes that permit holders must now follow.

The EPA published an interim guidance document that evaluates destruction and disposal technologies for PFAS and PFAS-containing materials, with a public comment period open through February 22nd. The guidance offers you options, not requirements.

PFAS, also known as “forever chemicals” refers to a class of thousands of synthetic man-made substances that have been used in industry and consumer products worldwide since the 1940s.
