Comparison: State vs. Federal

Rules. Massachusetts does not have authority from the U.S. Environmental Protection Agency (EPA) to administer the federal National Pollutant Discharge Elimination System (NPDES) permit program. Wastewater discharges in the commonwealth are subject to both federal and state permit requirements. The EPA and the Massachusetts Department of Environmental Protection (DEP) issue joint permits. Applications for NPDES permits must be submitted to and approved by EPA Region 1 and the DEP.

For Massachusetts NPDES permits, facility owners or operators must also mail an identical copy of the EPA application forms to the DEP. The NPDES permits become effective when signed by the director of the EPA Region 1 office in Boston and the director of the Massachusetts DEP.
