On January 18, 2022, the U.S. Environmental Protection Agency (EPA) issued the 2022 National Pollutant Discharge Elimination System (NPDES) Construction General Permit (2022 CGP) for stormwater discharges from construction activity. The 2022 CGP will become effective on February 17, 2022, replacing the 2017 CGP, which expires on February 16, 2022. This permit covers stormwater discharges from construction activities in areas where EPA is the NPDES permitting authority. New construction projects in these areas may submit a Notice of Intent (NOI) for coverage under the permit once it is effective.

Key changes in the permit include new or clarified provisions related to erosion and pollution prevention controls, dewatering discharges, turbidity benchmark monitoring for dewatering discharges to sensitive waters, and inspection training.

EPA will also host a webinar on February 24, 2022, at 1:00 PM (EST) to provide an overview of the 2022 CGP and an opportunity for participants to ask questions. You can register at https://www.zoomgov.com/webinar/register/WN_DsNwf8dQTzC1pCk0HCyVnQ.
