ENB Region 1 Completed Applications 11/23/2005

The Department is proposing to renew and modify the SPDES permit for the Northport Generating Station.  The Northport Generating Station consists of four oil and gas fired steam-electric generating units.  Each unit has a maximum net generating capacity of 386 megawatts (1544 megawatts total).  The station withdraws a maximum 643,000 gallons/minute (938 million gallons/day) of condenser cooling water from an intake canal off the Long Island Sound.   The canal, located on the west side of the station, ranges from 150 to 200 feet wide and 15 to 20 feet in depth.  The cooling water passes through a separate intake structure for each unit consisting of two intake bays, each with a skimmer wall, trash rack and standard vertical traveling intake screen (8 intake screens total).  The intake screens are about 10 feet wide, 27 feet deep, and contain 3/8 inch square wire mesh.

    This SPDES permit authorizes the discharge of non-contact cooling water, treated wastewater, boiler blowdown, storm water, and sanitary wastewater to both Long Island Sound and groundwater.  The modifications to the SPDES permit being contemplated by the Department requires Keyspan to submit data and analyses related to the once-through cooling system.  The information will be utilized by the Department to determine best technology available for minimizing adverse impacts to the aquatic resources of Long Island Sound. Keyspan will also be required to review possible technologies and operational measures to minimize aquatic impacts.  The information is being requested pursuant to 6 NYCRR Part 704.5 and 40 CFR 125 - Subpart J.

    The Northport Generating Station is located on the north shore of Long Island, within the Town of Northport.

    A copy of the draft SPDES permit and fact sheet are available for review at the DEC Region 1 office or by calling the contact listed below.

The applicant proposes to subdivide a 7.2 acre parcel into two residential lots of 3.95 and 3.25 acres each.  One dwelling currently exists on one of the proposed lots.  Any subsequent development located landward of the crest of the dune on the property will likely be beyond the jurisdiction of Article 25 (Tidal Wetlands Act).  The purpose of the project is to provide two lots for residential development. The proposed project is located at 164 Dune Road in the Village of Quogue, Town of Southampton in Suffolk County, SCTM# 902-16-02-04.
