• Rules. Connecticut is fully authorized by the U.S. Environmental Protection Agency (EPA) to develop and issue the National Pollutant Discharge Elimination System (NPDES) permits, including for discharges resulting from stormwater runoff. For additional information about Connecticut's wastewater discharge permit program, see the state section NPDES PERMIT.

Similar to the federal program, the state has developed NPDES general permits for stormwater discharges from industrial facilities, dewatering wastewaters and construction activities, and municipal separate storm sewer systems (MS4s). In addition, the state also has a general permit for commercial activities with 5 or more acres of contiguous impervious surfaces.

See the national section STORMWATER—GENERAL for more information on the federal program and the state sections STORMWATER—INDUSTRIAL FACILITIES, STORMWATER—CONSTRUCTION ACTIVITIES, and STORMWATER—MUNICIPALITIES for information on the state requirements for these specific types of stormwater discharges.
