EPA Revises Regulations for Small Municipal Storm Sewer Systems to Address Court Remand

The Environmental Protection Agency (EPA) is revising the regulations governing small municipal separate storm sewer system (MS4) permits in response to a court remand from the United States Court of Appeals for the Ninth Circuit, which found that the current regulations did not provide adequate public notice and opportunity for public input, and did not require permitting authorities to review best management practices to reduce pollutants in stormwater discharges.
