Program Overview
Small municipal stormwater sewer systems (MS4s) that are located within the boundaries of a Census Bureau defined "urbanized area" are regulated under EPA's Phase II Stormwater Rule. This requires MS4s to develop a stormwater management program that will reduce the amount of pollutants carried by stormwater during storm events to waterbodies to the "maximum extent practicable". The goal of the program is to improve water quality and recreational use of waterways.
MS4 stormwater programs have six elements called minimum control measures (MCM) that when implemented together, are expected to result in a reduction of pollutants discharged into waterbodies.
Discharges from Municipal Separate Storm Sewer Systems (MS4s) in Urbanized or Additionally Designated Areas must be authorized in accordance with a permit for stormwater discharges from MS4s. This page contains the General Permit for Stormwater Discharges from Municipal Separate Storm Sewer Systems and the forms necessary to obtain coverage under that permit.
