Comparison: State vs. Federal
• Rules. Under the Rhode Island Pollutant Discharge Elimination System (RIPDES), the state is authorized by the U.S. Environmental Protection Agency (EPA) to administer its own stormwater discharge permit program, including general permit authority for stormwater discharges associated with municipal separate storm sewer systems (MS4s). Rhode Island follows the federal requirements for MS4 permitting but issues its own general and individual MS4 stormwater permits. See the national section STORMWATER —MUNICIPALITIES for more information on the federal program.
• Administration and enforcement. The DEM administers and enforces the stormwater discharge permit program in Rhode Island.
