NPDES Permits in New England

Dewatering General Permit (DGP)

Draft general permit available for Massachusetts and New Hampshire

Draft Dewatering General Permit (DGP)

The Notice of Availability of the Draft NPDES General Permit for Dewatering Activity Discharges in Massachusetts (MAG070000) and New Hampshire (NHG070000) was published in the Federal Register on July 17, 2014.

This General Permit replaces the Dewatering General Permit (DGP) that expired on September 30, 2013. The Draft 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 and the State of New Hampshire. The draft 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 draft 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.
