The following are resources to assist NH Municipal Small Separate Storm Sewer System (MS4) communities with meeting the 2003 and 2017 EPA MS4 permit requirements.

Seacoast NOI Template and Guidance:

The documents below were produced collaboratively with the Seacoast Stormwater Coalition and Rockingham Planning Commission.  The materials are intended to assist with the preparation of the MS4 NOI for NH Communities.  Please note that some of the information is specific to the communities contained within the Seacoast Stormwater Coalition.

Part II: Summary of Receiving Waters

  • NH MS4 Permit Related Impairments Status Based on NH 2012 303(d) list in 2017 EPA MS4 Permit Based on NH 2012 303(d) list in 2017 EPA MS4 Permit. This is a spread sheet based on the information in the 2017 MS4 permit indicating what impairments each MS4 has. May be used for initial planning purposes for the Minimum Control Measure #1: Outreach and Education requirements related to impairments.  With the 2016 303(d) list partially approved by EPA, there may be some minor changes to this list to consider.
