On May 18, 2016, the U.S. Environmental Protection Agency (“EPA”) proposed changes to the discharge permit program that will affect all dischargers and the terms and conditions in their future permits. The proposed rule would revise several key components of the agency’s National Pollutant Discharge Permit System (“NPDES”) program, including provisions that impact states with delegated authority under the Clean Water Act to administer their own NPDES permitting programs.1 In response to requests from interested stakeholders, EPA extended the period for submitting public comments on the proposal. Comments are now due on Aug. 2, 2016.2
