Comparison: State vs. Federal

Rules. Massachusetts is not authorized by the U.S. Environmental Protection Agency (EPA) to administer the federal National Pollutant Discharge Elimination System (NPDES) permit program, which includes stormwater discharges. Facilities must obtain permits from EPA's Region 1 office. See the national section STORMWATER—GENERAL for a review of the federal stormwater permitting program.

Massachusetts, in conjunction with the EPA, issues general permits for the coverage of surface water discharges associated with small municipal separate storm sewer systems (MS4s). See the state section STORMWATER— MUNICIPALITIES for more information. The Massachusetts Department of Environmental Protection (DEP) also requires review of all Stormwater Pollution Prevention Plans (SWPPPs) that cover discharges to Outstanding Resource Waters (ORWs) associated with construction and industrial activities. See the state sections STORMWATER—INDUSTRIAL FACILITIES and STORMWATER—CONSTRUCTION ACTIVITIES
