The Department has prepared a draft permit and made a tentative determination to issue a renewed and modified Title V Air permit for the National Fuel Gas Supply Corporation Independence Station Facility. The facility is a natural gas storage facility consisting of four natural gas fired stationary reciprocating internal combustion compressor engines, two rated at 1000 HP and two rated at 1500 HP, one 302 HP Kohler Model 200REZXB spark ignition emergency generator which, as the only permit modification, replaced one 200 HP emergency generator which was decommissioned on September 12, 2018, and two natural gas triethylene glycol (TEG) dehydration units. Other exempt equipment includes a boiler, hot water heater, parts washer, and nine tanks. The dehydration units use a regenerative glycol system to remove water that accumulates in the natural gas during underground storage at the facility. The dehydration units are subject to 6NYCRR Part 212 which requires process emissions to meet air pollution control standards. The compressor engines are subject to the nitrogen oxides (NOx) emission limit for lean burn spark ignited natural gas fired stationary internal combustion engines. The NOx limit is 1.5 grams per brake horsepower-hour per 6 NYCRR Part 227-2.4(f)(1). Source performance testing performed in 2019 has confirmed compliance with the limit. 

In accordance with 6NYCRR Parts 621.7(b)(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.
