Project Description:
The Department has prepared a draft permit and has made a tentative determination, subject to public comment or other information, to approve Title V and Title IV permit renewals for the Port Jefferson Energy Center facility located at 700 Beach St, Port Jefferson, NY. The facility consists of two (2) identical LM6000 combustion turbines, fired primarily on natural gas, with #2 distillate oil as backup. Water injection and selective catalytic reduction (SCR) are employed for control of oxides of nitrogen (NOx) emissions. There are no substantive changes to the permit.

The facility has previously accepted emission caps for particulate matter, carbon monoxide, and oxides of nitrogen, so emissions are below the new source review (NSR) thresholds for non-attainment areas and Prevention of Significant Deterioration requirements. It is permitted as a Title V facility because of its Title IV status.

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.

Persons wishing to inspect the subject Title V files, including the application with all relevant supporting materials, the draft permit, and all other materials available to the DEC (the "permitting authority") that are relevant to this permitting decision should contact the DEC representative listed below.
