Small MS4 General Permit Update
(December, 2014)

2013/2014 Small MS4 General Permits

EPA has revised the two previous Draft Massachusetts MS4 Permits and the new 2014 Draft Massachusetts MS4 Permit was published in the Federal Register on September 30, 2014. The original public comment period was from September 30, 2014 through December 29, 2014, however EPA has reopened the comment period and will accept comments until February 27, 2014. EPA is currently in the process of responding to comments received on the 2013 Draft New Hampshire MS4 permit and plans to issue it final in the summer of 2015.

Provided below is additional information and a brief chronology for each of the draft permits for Stormwater Discharges from Small Municipal Separate Storm Sewer Systems (MS4s) in New Hampshire and Massachusetts:

New Hampshire

Massachusetts

  • The previous draft North Coastal and Interstate, Merrimack, and South Coastal (JMS) Small MS4 draft permits have been combined and issued as a single draft Massachusetts permit. For more information on the Draft Massachusetts Small MS4 permit, as well as information on the previous draft permits for the North Coastal and IMS watersheds, public hearing information and public meeting information, see: http://www.epa.gov/region1/npdes/stormwater/MS4_MA.html
  • Massachusetts Department of Transportation (MassDOT): EPA anticipates issuing a separate individual small MS4 permit for MassDOT with a draft available in the near future.

Anyone who wishes to receive information regarding a draft general permit should send their contact information to Glenda Velez (velez.glenda@epa.gov) with "Draft MS4 Information Request" indicated in the subject line.

The effective date of each final general permit will be no sooner than the date the final permit is signed and made publicly available. To obtain coverage, Operators will be required to submit a new Notice of Intent (NOI) for the permit for which they are eligible. EPA anticipates that NOIs will be due ninety (90) days after the effective date of each final permit.

The draft small MS4 general permits released to date include the same six minimum control measures as the 2003 MS4 general permit in addition to provisions to protect water quality standards. To improve the effectiveness of stormwater management programs and reduce the adverse effects of stormwater runoff on receiving waters, these draft permits include:

  • enhanced illicit discharge detection and elimination (IDDE) requirements to identify, isolate and remove sanitary and other wastes from the stormwater system;
  • water quality monitoring of stormwater discharges;
  • encouragement of low impact development and green infrastructure techniques; and
  • requirements designed to implement approved total maximum daily load (TMDL) waste load allocations (WLAs).
