ENB Region 2 Completed Applications 08/24/2005

The Department is proposing to renew and modify the SPDES permit for the Far Rockaway Generating Station, Unit 4.  The Far Rockaway Generating Station consists of one natural gas fired steam electric unit with a net electrical generating capacity of 112 megawatts. The unit is cooled by a once-through system that draws water from Bayswater Channel (an excavated canal on the south shore of Mott Basin) through a shoreline intake structure. The system consists of two cooling water circulator pumps with a combined rated capacity of 57,000 gallons per minute (GPM) or 80 million gallons per day (MGD), four conventional vertical traveling screens with 0.375 inch mesh, and two vertical trash racks with 3 inch bar spaces.

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 the impacts from impingement and entrainment on the aquatic resources  of Mott Basin.  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 Far Rockaway Station is located on the south shore of  Mott Basin, a small enclosed bay on the eastern end of the Jamaica Bay complex.  

A copy of the draft SPDES permit and fact sheet are available for review.   

   

The applicant proposes to make certain improvements to a portion of the 63rd Street Tunnel located in the East River.  The improvements include the addition of a levelling bed and scour protection.
