Draft MS4 Permit Revised For New Hampshire Municipalities

EPA has released a revised draft New Hapshire small “Municipal Separate Storm Sewer System” (MS4) General Permit for public review and comment. The draft general permit has been published in the Federal Register. Public comments must be submitted by April 15, 2013.

The general permit will apply to 60 municipalities located in an urbanized area as defined by the 2010 census. Regulated MS4s include traditional cities and towns, state and federally owned facilities such as universities and military bases, and the state transportation agency (NHDOT). The draft general permits will apply to all the regulated MS4s, although waivers are possible for eligible municipalities within the urbanized area where population is less than 1,000.

  The revised draft permit updates the previous general permit finalized in 2003. EPA previously released draft general permits for small MS4s in NH in 2008. EPA decided to release revised draft general permits to account for significant public comments received on the 2008 proposal, the availability of updated demographic information from the 2010 Census, and several recently approved TMDLs for various waters in New Hampshire.
