Notice of Availability of Final NPDES General Permits MAG640000 and NHG640000 for Discharges From Potable Water Treatment Facilities in the Commonwealth of Massachusetts (Including Both Commonwealth and Indian Country Lands) and the State of New Hampshire: The Potable Water Treatment Facility General Permit (PWTF GP)

요약

The Director of the Office of Ecosystem Protection, EPA-New England, is issuing a notice of availability of the final National Pollutant Discharge Elimination System (NPDES) general permits for potable water treatment facility (PWTF) discharges to certain waters of the Commonwealth of Massachusetts (included both Commonwealth and Indian country lands) and the State of New Hampshire. These General Permits replace the previous PWTF GP, which expired on November 15, 2005. The final PWTF GP establishes Notice of Intent (NOI) requirements, effluent limitations, standards, prohibitions, and management practices for facilities with discharges from potable water treatment facilities. Owners and/or operators of these facilities, including those currently authorized to discharge under the expired General Permit, will be required to submit an NOI to be covered by the PWTF GP to both EPA-New England and the appropriate state agency. After EPA and the State have reviewed the NOI, the facility will receive a written notification from EPA of permit coverage and authorization to discharge under the General Permit.
