Oswego County

Applicant:

Oswego Harbor Power LLC

Oswego, NY 13126

Facility:

Oswego Harbor Power
261 Washington Blvd
Oswego, NY 13126

Application ID:

7-3512-00030/00004

Permit(s) Applied for:

Article 17 Titles 7 & 8 Industrial SPDES - Surface Discharge

Project is Located:

Oswego, Oswego County


Project Description:

The Department is proposing to modify the SPDES permit for the NRG Energy Oswego Harbor Power Generating Station as determined by the Environmental Benefit Permit Strategy (EBPS) priority ranking list. NRG Energy Oswego Harbor Power is a 2,100 MW oil and gas fired power plant located on the eastern basis of Lake Ontario. The station consists of six units. Units 1-4 have a combined capacity of 400 MW and, though currently permitted, are not operating. Units 5 and 6 are operational, and more recently constructed, and rated at 850 MW each.

Three offshore cooling water intake structures (CWIS) fitted with velocity caps are permitted to operate, withdrawing up to approximately 1,400 MGD from Lake Ontario. One intake supplies cooling water to Units 1-4 with a combined flow of 492 MGD. Though the units are no longer operational, the pumps are used under an agreement with the City of Oswego to flush Oswego Harbor Turning Basin. Units 5 and 6, the two operational turbines, have a combined capacity of 905 MGD and withdraw via separate intake structures. Additional service water used at the facility makes up the remaining capacity. When the facility is not operating at maximum capacity, only one of two pumps is operated at each unit, thereby reducing intake flow by 50 percent. Cooling water is returned at three different locations: units 1-4 discharge at shoreline while units 5 and 6 discharge through tunnels and diffusers 1,360 and 2,650 feet from shore respectively. Units 5 and 6 have a maximum delta T of 31 F. A total of eight automatic conventional traveling screens with 3/8 inch mesh are used to collect debris and fish when the CWIS is in operation. Unit 6 includes a fish diversion and return system upstream from the traveling screens.

The SPDES permit authorizes the discharge of this cooling water. The proposed modifications involve reduction of the vanadium discharge limit, addition of new biological monitoring requirements (see page 10), new thermal discharge study requirements (page 13), new best management practice requirements (page 14), and a new schedule of compliance page (page 19). The new biological monitoring requirements include: 1) an impingement mortality and entrainment characterization study; 2) a design and construction technology review; 3) a plan to implement technologies and/or operational measures per 6NYCRR 704.5 and Section 316(b) CWA; and 4) a verification monitoring plan.

Availability of Application Documents:

Filed application documents, and Department draft permits where applicable, are available for inspection during normal business hours at the address of the contact person. To ensure timely service at the time of inspection, it is recommended that an appointment be made with the contact person.
