NPDES Permits in New England

Dewatering General Permit (DGP)

The Notice of Availability of the Final NPDES General Permit for Dewatering Activity Discharges in Massachusetts (MAG070000) and New Hampshire (NHG070000) was published in the Federal Register on October 7, 2008.

This General Permit replaces the Construction Dewatering General Permit (CDGP) that expired on September 23, 2007. The Final General Permit provides coverage for facilities with construction dewatering of groundwater intrusion and/or storm water accumulation from sites less than one acre and short-term and long-term dewatering of foundation sumps into waters of the Commonwealth of Massachusetts (including both Commonwealth and Indian country lands) and the State of New Hampshire. The permit establishes permit eligibility conditions, notice of intent requirements, effluent limitations, standards, prohibitions, and best management practices. The eligibility requirements for coverage under the general permits are discussed in detail under Part 3 of the permit. The reader is strongly urged to go to that section to determine eligibility.

Owners and/or operators of facilities with dewatering discharges, including those currently authorized to discharge under the expired General Permits, will be required to submit a Notice of Intent (NOI) to be covered by the General Permit to both EPA-New England and the appropriate state agency. EPA and the State will review the NOI and the facility will receive written notification from EPA stating whether permit coverage and authorization to discharge under one of the general permits is approved.

NOIs may be sent via USPS, email, or fax to EPA at EPA-Region 1, Office of Ecosystem Protection (OEP06-3), 5 Post Office Square, Boston, Massachusetts, 02109-3912; email address GeneralPermit.Dewatering@epa.gov; or fax number (617) 918-0828. Notification information shall be submitted to the appropriate State agency at the addresses listed at Part 5 of the General Permit.
