EPA Finalizes the 2022 Construction General Permit (CGP)

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. This permit covers stormwater discharges from construction activities in Massachusetts and New Hampshire that disturb one or more acres of land. Construction activity includes earth-disturbing activities such as clearing, grading, and excavating land and other construction-related activities that could generate pollutants. The 2022 CGP will become effective on February 17, 2022, replacing the 2017 CGP, which expires on February 16, 2022. 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.
