Project Description:
The Department has prepared a draft permit and has made a tentative determination, subject to public comment or other information, to approve this application to renew the Air Title V and Air Title IV permit for this electric power generating station.

The Northport Power Station consists of three emission units: four (4) 385 MWe turbine/generator boiler sets (operating on natural gas, No. 1, 2, or 6 fuel oils), a 15 MWe black start combustion turbine and a 430-horsepower diesel startup engine, the latter two running on No. 1 or No. 2 distillate oil. Fuel storage includes 5 main tanks for storing No. 6 oil and various smaller tanks for distillate, lubrication, and dielectric oils. The power station uses an electrostatic precipitator for emission control, which is not operated when firing natural gas.Continuous Emission Monitoring Systems (CEMS) are in place to monitor the NOx emissions from the four turbine/generator boiler sets and to maintain compliance with the EPA Haze Rule. Northport Power Station has opted to continue to meet compliance with the requirements of 6NYCRR Part 227-2 on a system wide basis using NOx RACT Compliance Plan.

This renewal does not include changes to the facility equipment or processes and does not authorize an increase in emissions. The permittee will be required to maintain records and report this data to verify compliance with permit conditions and limits. Pursuant to the requirements of section 7(2) of the Climate Leadership and Community Protection Act (CLCPA), the Department has requested and received information regarding the project’s consistency with CLCPA.

In accordance with 6NYCRR Parts 621.7(d)(9) and 201-6.3(c), the Administrator of the United States Environmental Protection Agency (USEPA) has the authority to bar issuance of any Title V Facility Permit if it is determined not to be in compliance with applicable requirements of the Clean Air Act or 6NYCRR Part 201.
