Notice of Determination to Issue Prevention of Significant Deterioration (PSD) Permit

Applicant: Southern Energy Bowline L.L.C., 400 Rella Boulevard, Suite 157, Suffern, New York 10901

Application Number: DEC # 3-3922-00003
PSC Case # 99-F-1164

Project Description: The Applicant, Southern Energy Bowline, L.L.C., has applied for a Prevention of Significant Deterioration pre-construction permit pursuant to 40 CFR 52.21 and for a Certificate of Environmental Compatibility and Public Need under Article X of the NYS Public Service Law so that it may construct and operate Bowline Unit #3, a combined cycle electric generating facility consisting of three General Electric Steam and Gas (STAG) 107F system combustion turbine generators (CTG), three heat recovery steam generators (HRSG), one steam turbine generator (STG) and associated balance-of-plant systems and facilities. The primary fuel will be natural gas and low (0.05 percent) sulfur fuel oil will be used for back-up. The nominal electric generating capacity of the proposed Facility will be approximately 750 megawatts (MW). The New York State Department of Environmental Conservation (NYSDEC) has conducted the Prevention of Significant Deterioration (PSD) review contained in 40 CFR 52.21 and 124.

Public Notice: The New York State Department of Environmental Conservation (NYSDEC) has made a tentative determination that the proposed construction of a 750MW natural gas-fired combined cycle combustion turbine generating plant by Southern Energy Bowline, LLC is subject to and satisfies the federal requirements for the Prevention of Significant Deterioration (PSD) contained in 40 CFR 52.21. The air emissions will result from the turbines and generators and will be vented through a single 286-foot high exhaust stack.

The following PSD affected air pollutants will be controlled with the Best Available Control Technology (BACT): nitrogen oxides (NOx), sulfur dioxide (SO2), carbon monoxide (CO), particulate matter (PM & PM10) and sulfuric acid mist (H2SO4). The DEC Staff has also verified that the emissions of these PSD affected air pollutants will not cause or significantly contribute to an exceedence of any national primary or secondary ambient air quality standards, and will not consume more than the allowable PSD air quality increment where one exists. In fact, the projected maximum concentrations of the PSD affected criteria pollutants are below EPA defined significance levels. The facility is also affected by federal New Source Performance Standards (NSPS) at 40CFR Part 60. In addition to the operating restrictions and emission limitations proposed by Southern Energy for Unit 3, which have been incorporated as special permit conditions, DEC staff have imposed limitations on the draft PSD permit to assure compliance with CO BACT requirements and reductions in ammonia emissions, as provided in the “fact sheet” in the administrative record and as summarized below.

Project Location: The Energy Facility would be located adjacent to two existing power facilities, Bowline Units 1 and 2, off of Samsondale Avenue in the Town of Haverstraw, Rockland County, New York, on part of a 257 acre parcel owned by the applicant. The entire project area is zoned Planned Industrial Office. The project site is bounded on the east by Bowline Point Park and the Hudson River, on the west by a public park (Peck’s Pond), on the south by combined residential and light industry properties, and on the north by Keahon Auto Wreckers. In addition, vacant land comprising approximately 97 acres of the total 257 acres also occupies the northern portion of the overall Bowline Generating Station property.

NYS Public Service Law: This project is subject to review pursuant to Article X of the New York State Public Service Law (Siting of Major Electric Generating Facilities) and requires a Certificate of Environmental Compatibility and Public Need (Certificate) to construct and operate a 750 megawatt natural gas-fired combined cycle combustion turbine generating facility. The Article X application was filed on March 20, 2000. To date, it has been subject to a public hearing held on September 12, 2000, at Haverstraw Town Hall.

Other Regulatory Provisions: In addition to the specific regulations cited above, the entire Article X application is being processed by the NYS Department of Environmental Conservation (NYSDEC) pursuant to Environmental Conservation Law (ECL) Article 3, Title 3 (General Functions), ECL Article 17 (Water Pollution Control), ECL Article 19 (Air Pollution Control), and 6 NYCRR Part 201 (Permits and Registrations) and Subpart 231-2 (Requirements for Emission Sources Subject to §§172 and 173 of the Clean Air Act , 42 USC §7502 and §7503 on or after November 15, 1992), Part 621 (Uniform Procedures). A separate notice will be issued for comment on the 6 NYCRR Part 201 and SPDES draft permits.

SEQRA Status: The NYS Department of Environmental Conservation (NYSDEC) has determined that the proposed action is a Type II action [617.5(c)(35)], and is not subject to review pursuant to the State Environmental Quality Review Act (SEQRA) (ECL Article 8) and 6NYCRR Part 617. A comprehensive environmental review is being conducted pursuant to PSL Article X.

Tentative DEC Staff Position: NYS DEC staff have reviewed the PSD permit application and determined it is complete pursuant to 6 NYCRR Part 621. Staff have determined that all statutory and regulatory criteria can be met through the imposition of special conditions. A draft PSD determination and permit is thus being made available for comment.

The emissions limits and special permit conditions imposed on the Bowline Unit 3 construction and operations reflect those proposed and analyzed by Southern Energy in their PSD permit application (Appendix 5B of the March, 2000 Article X application). In addition, DEC staff have determined and EPA Region II staff have concurred that the CO emission limits originally proposed by Southern Energy for both gas and oil firing were not BACT. Thus, the draft permit reflects lower limits which have been determined by DEC staff to constitute BACT and which are further specified to be achieved by the imposition of a CO catalyst. This determination is supported by the “fact sheet” for the project, including the determination that the CO catalyst also results in Lowest Achievable Emission Limit (LAER) for Volatile Organic Compounds (VOCs), as required by 6 NYCRR SubPart 231-2, which in itself redefines CO BACT. Furthermore, DEC staff have established an emission limit for ammonia “slip” at half that proposed by the applicant based on permitted levels in the Northeast states.

Public Comments/Appeal Procedure: NYSDEC invites public comment regarding this tentative determination. NYSDEC’s final determination will be made only after full consideration of all public comment received. Comments are to be limited to PSD concerns and must be in writing, and must be accompanied with adequate supporting information. The PSD aspects, as noted above, address the proposed emissions of nitrogen oxides (NOx), sulfur dioxide (SO2), carbon monoxide (CO), particulate matter (PM and PM-10), and sulfuric acid mist (H2SO4). The public comment period will run from the date of publication of this public notice until December 14, 2000. The final determination may be appealed administratively within 30 days of Southern Energy LLC’s receipt of the final PSD permit determination. Only those persons who file comments on this PSD preliminary determination may petition the EPA Environmental Appeals Board for administrative review of the PSD determination. Persons who fail to file comments may petition for review only to the extent of any changes from the draft to the final permit decision regarding PSD issues. If no comments are received and NYS DEC makes no changes to the PSD determination from the draft to the final decision, no opportunity for further review or appeal will be available.

Any petition for EPA review must be made within thirty (30) days of the service of notice of the final decision. The procedures for administrative review are defined in the Consolidated Permit Regulations at 40 CFR Part 124. Any such petition for review shall include a statement of the reasons supporting that review and shall adhere to the standards outlined in 40 CFR §§ 124.19(a)(1) and (2).

Upon completion of the administrative review process (if applicable), the final decision will become the final agency action and will be published in the Federal Register. Those who appealed for administrative review may petition for judicial review within 60 days of the final EPA decision.
