On May 1, 2003, EPA Region 1 issued its Final General Permit for Stormwater Discharges from Small
Municipal Separate Storm Sewer Systems (2003 small MS4 permit) consistent with the Phase II rule. The 2003 small MS4 permit covered "traditional" (i.e., cities and towns) and "non-traditional" (i.e., Federal and state agencies) MS4 Operators located in the states of Massachusetts and New Hampshire. Under the 2016 MS4 general permit, which became effective on July 1, 2018, the town of Amherst was added as an urbanized area, thus UMass Amherst falls under the “non-traditional General Permit# MAR042056. The permit expires on July 1, 2023. The permit is issued and managed by both the US Environmental Protection Agency (EPA) and the Massachusetts Department of Environmental Protection (MADEP).
