Comparison: State vs. Federal
• Rules. New Hampshire is not authorized by the U.S. Environmental Protection Agency (EPA) to administer the federal National Pollutant Discharge Elimination System (NPDES) permit program for municipal separate storm sewer systems (MS4s). See the national section STORMWATER—MUNICIPALITIES for more information on the federal MS4 stormwater permitting in the state.
• Administration and enforcement. EPA Region 1's office administers the federal stormwater permitting program in New Hampshire. However, a state-specific Notice of Intent (NOI) must be submitted for coverage under the NPDES General Permit for small MS4s to the DES Permits and Compliance Section. A copy of this NOI can be accessed in Forms in this section.
For MS4s in the coastal watershed, there are two grants administered by the DES that can help pay for required elements of one of the six minimum control measures, illicit discharge detection and elimination, as required for the stormwater management program under the federal regulations. Funding for these grants is provided by the New Hampshire Estuaries Project.
