Permit(s) Applied for:

Article 19 Air Title V Facility

Project is Located:

Concord, Erie County

Project Description:

The Department has prepared a draft permit and has made a tentative determination to issue a renewal of the Title V Air Permit for the above-referenced facility. The National Fuel Gas Supply Corporation (NFGSC) Concord Facility is a natural gas transmission facility. This facility consists of five (5) permitted natural gas compressor engines (emission unit U-00001) and one (1) natural gas-fired compressor turbine (emission unit U-00002) used to compress natural gas in NFGSC's transmission pipeline. The facility also operates the following permit-exempt sources: one (1) emergency generator; one (1) boiler; one (1) water heater; two (2) parts washers; and nine (9) storage tanks.

The turbine is limited to NOx emissions concentrations of 25 parts per million by volume on a dry basis adjusted to 15 percent oxygen to meet the requirements of 40CFR60 Subpart KKKK for new turbines firing natural gas with a heat input between 50 and 850 MMBtu/hr. Compliance with this emission standard shall be determined according to the annual performance tests as specified in §60.4340 and §60.4400.

The emission limit for sulfur dioxide from a stationary combustion turbine is 0.060 lb SO2/MMBtu heat input. NFGSC will not burn fuels which contain total potential sulfur emissions in excess of the limit. The turbine is also subject to 6NYCRR Part 227-1.3(a) which limits the opacity of emissions to less than 20%.

The emergency generator, rated at 791 HP, respectively, is exempt from permitting per 6 NYCRR Part 201-3.2(c)(6) since it is operated less than 500 hours per year. The generator is subject to 40CFR63 Subpart ZZZZ, and 40CFR60 Subpart JJJJ.

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.

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. The Draft Permit and Permit Review Report may be viewed and printed from the Department web site at:

SEQR Lead Agency: None Designated

State Historic Preservation Act (SHPA) Determination:

The proposed activity is not subject to review in accordance with SHPA. The application type is exempt and/or the project involves the continuation of an existing operational activity.

Coastal Management:

This project is not located in a Coastal Management area and is not subject to the Waterfront Revitalization and Coastal Resources Act.

DEC Commissioner Policy 29, Environmental Justice and Permitting (CP-29)

It has been determined that the proposed action is not subject to CP-29.
