Astoria Generating Company, L.P.

January 8, 2003

STATE OF NEW YORK
DEPARTMENT OF ENVIRONMENTAL CONSERVATION
ANNOUNCEMENT OF PUBLIC COMMENT PERIOD, and
COMBINED RENOTICE OF COMPLETE APPLICATION,
PUBLIC HEARING and ISSUES CONFERENCE

Applicant: Astoria Generating Company, L.P., 18-01 20th Avenue, Astoria, NY, 11105

Application Number: DEC # 2-6301-00185/00016 - Part 201 Air State Facility; DEC#: 2-6301-00185/00017 - Title IV Acid Rain; DEC#: 2-6301-00185/00007 - State Pollution Discharge Elimination System (SPDES); PSC Case # 00-F-1522

RENOTICE OF MODIFIED APPLICATION: As a result of an operational condition for the repowering of the Astoria Generating Station by Astoria Generating Company, L.P. ("Applicant"), the project has been modified to include a reverse osmosis system. The reverse osmosis system will remove salt from the cooling water taken in from the East River, thus significantly reducing total particulate emissions from the cooling towers (from 127 to 9 tons per year). In addition, as a result of re-calculations of emission rate for sulfuric acid mist (H2SO4) for the repowering of the Astoria Generating Station by Astoria Generating Company, L.P. ("Applicant"), the Applicant has supplemented its application and requested a modification of the previously noticed limits. The revised limits result in an increase in emissions of H2SO4 above the PSD applicability threshold for the project and are, therefore, being renoticed.

The limited changes to the Department's permits as a result of the reverse osmosis system are described below.

The Part 201 permit was previously noticed in the Environmental Notice Bulletin on January 2, 2002 with a minimum 30 day comment period which ended on February 15, 2002. Comments on the draft air permit were received from the Applicant and intervenors. The re-noticed draft 201-6 permit incorporates the Applicant's comments. The specific changes are provided in the "Comment and Response Summary for the Part 201-6 Permit", which is available upon request. This document is not the requisite "Responsiveness Summary" which will be made available with the noticing of the final permits and will include response to the intervenors comments.

Project Description:The Applicant proposes to repower the existing Astoria Generating Station (AGS). The repowering will include the installation of six new combustion turbines, retirement of four existing boilers and reuse of existing equipment and infrastructure including two steam turbine generators. The repowering will increase AGS's electric generating capacity from 1,254 MW to 1,816 MW.

The primary fuel will be natural gas with kerosene (0.04 % sulfur by weight) or equivalent sulfur content member of the distillate oil facility used as back up fuel for a maximum of 750 hours per year. The Applicant proposes to install an oxidation catalyst system to reduce carbon monoxide (CO) and volatile organic compounds (VOCs), and a selective catalytic reduction system (SCR) to reduce Nitrogen Oxides (NOx). Air emissions resulting from the turbines and heat recovery steam generators (HRSG) will be emitted through six 340 foot tall stacks. The repowering will incorporate a closed-loop condenser cooling system using a plume abated evaporative cooling tower to cool the circulating water.

Project Location: The AGS facility is located at 18-01 20th Avenue in Astoria, Queens and is located within a larger complex known as the Consolidated Edison (ConEd) site. The ConEd site is bounded on the north and west by the East River, the east by Luyster Creek (Steinway Creek) and 37th Street, and the south by 20th Avenue.

State Pollutant Discharge Elimination System (SPDES)

SPDES Permit: The Department previously noticed the draft SPDES permit for the repowering of AGS. To reflect the changes required by the reverse osmosis system, the Applicant has submitted, pursuant to Environmental Conservation Law (ECL) §17-0823, a revised application with the DEC for a SPDES wastewater discharge permit modification and a request for certification that its discharges will comply with the applicable provisions of §§301, 302, 303, 306 and 307 of the federal Clean Water Act. The application was filed originally on February 19, 2001, and as amended on August 17, 2001, October 29, 2001, and November 27, 2002 (reverse osmosis system).

DEC Staff has concluded that the application for this permit is complete within the meaning of Title 6 of the New York Code of Rules and Regulations (6NYCRR) §621.1(d), has prepared a draft SPDES permit and fact sheets pursuant to 6 NYCRR §621.5(d)(7) and has tentatively determined to issue this permit.

The addition of the reverse osmosis system will increase the water intake requirements of the repowering from a maximum of 17.5 million gallons per day (mgd) to 34.6 mgd. Water will continue to be withdrawn from the East River via an intake structure located at the facility. (Water withdrawal for the existing facility averages 1,250 mgd.) With the Reverse Osmosis system, the proposed maximum discharge back to the East River will be 19.3 mgd.

Air Permit Applications

Air Permits: Below is a summary of the proposed changes to the draft air permits:

Permit Changes/Reason
Preconstruction permit pursuant to 6 NYCRR §201-6.1 Reduction in PM/PM10 from the use of reverse osmosis system.
Preconstruction permit pursuant to 6 NYCRR §201-6.1 Numerous minor changes suggested by the applicant during the previous comment period.
Preconstruction permit pursuant to 6 NYCRR §201-6.1 Increased sulfuric acid (H2SO4) emission limits which trigger Prevention of Significant Deterioration (PSD) applicability pursuant to 40 CFR §52.21.

Consequently, DEC staff has prepared draft permits pursuant to 6 NYCRR §621.5(d)(7) and are available for review. DEC Staff has determined that the conditions in the draft preconstruction permit authorize the construction and operation of the proposed facility and assure conformance of the facility with all applicable State and federal air pollution control regulations including the requirements of 6 NYCRR Parts 201, 204, 225, 227, 231, and 257, as well as all New Source Performance Standards (NSPS) at 40 CFR Part 60.

In addition to the terms of the Subpart 201-6 preconstruction permit for the proposed project, DEC Staff have imposed special restrictions to emissions of Nitrogen Oxides (NOx), Particulate matter (PM10) and Sulfur Dioxide (SO2) in the existing facility's proposed Title V permit to eliminate projected exceedences of the ambient standards. These limitations were proposed by the Applicant in accord with a modeling analysis, dated October 11, 2001, which demonstrated that the cumulative impacts of the existing facility under these limitation and the cumulative impacts from other nearby existing and proposed facilities will be below the applicable ambient standards.

The terms and conditions of the draft PSD permit are not subject to public hearing under State administrative procedures. Reference to the PSD permit in this notice is for informational purposes only. The DEC is concurrently issuing for public comment a Notice of Determination to Issue Prevention of Significant Deterioration (PSD) Permit pursuant to 40 CFR §52.21and Part 124.

Additional Regulatory Provisions

NYS Public Service Law (PSL): This project requires a Certificate of Environmental Compatibility and Public Need (Certificate) to construct and operate, and is subject to review pursuant to New York State Public Service Law (PSL) Article X (Siting of Major Electric Generating Facilities). The PSL Article X application was filed on October 29, 2001. The conditions contained in the draft permits identified in this notice will be incorporated into the Article X hearing record for the repowering project.

The DEC public hearings noticed below are being held jointly with the related PSL Article X proceedings concerning the Article X application filed by Orion Power, for a Certificate for the repowering of the AGS (PSC Case #00-F-1256). For additional information

concerning the PSL Article X application and related hearings, go to the Department of Public Service web page at: http://www.dps.state.ny.us/orionpower.html

NYS Environmental Conservation Law and implementing regulations: In addition to the specific statutes and regulations cited above, the subject SPDES as well as the preconstruction and Phase II Title IV air permit applications are being processed by the DEC pursuant to ECL Article 3, Title 3 (General Functions), ECL Article 17 (Water Pollution Control), ECL Article 19 (Air Pollution Control), and 6 NYCRR Subparts 201-6 (Permits and Registrations) and 231-2 (Requirements for Emission Sources Subject to §§172 and 173 of the Clean Air Act , 42 USC §7502 and §7503), Part 621 (Uniform Procedures), Part 624 (Permit Hearing Procedures), and Parts 750-758 (State Pollutant Discharge Elimination System).

SEQRA Status: The DEC Staff has determined that the proposal is a Type II action as designated by 6 NYCRR §617.5(c)(35). A comprehensive environmental review is being conducted pursuant to PSL Article X.

SHPA Status: A cultural resource survey has been completed. This project is subject to Article X of the Public Service Law and the New York State Department of Public Service will ensure compliance with the State Historic Preservation Act (SHPA) through consultation with the Office of Parks Recreation and Historic Preservation.

Tentative DEC Staff Position and Document Availability: DEC Staff has reviewed the revised application materials and supplemental documentation and has determined that they are complete pursuant to 6 NYCRR Part 621. A tentative determination has been made to approve the revisions and revised draft permits have been prepared. It has been determined that all air program statutory and regulatory criteria can be met through the imposition of special permit conditions. For the 201-6 draft air preconstruction permit, the DEC has incorporated control technologies and emission limits proposed by the Applicant, and has independently developed additional conditions to ensure compliance with all regulatory requirements. The background documentation of this determination is available in the "fact sheets" and the administrative record for the project.

Public Hearings Sessions and Issues Conference

Legislative Public Hearing: Legislative hearing sessions to receive unsworn statements from the public on the applications and the draft permits, described above, will be held before Administrative Law Judge P. Nicholas Garlick, on February 12, 2003 at 7:00 p.m. at Riccardo's by the Bridge, 21-01 Twenty-fourth Avenue, Astoria, Queens, 11102 (for directions see www.riccardoscatering.com) As stated above, this hearing is being held on a joint record with the related PSL Article X proceedings. All persons, organizations, corporations, or government agencies which may be affected by the proposed project are invited to attend the hearing and to submit oral or written comments. It is not necessary to file in advance to speak at the legislative hearing. Lengthy statements should be in writing and summarized for oral presentation. Reasonable time limits may be set for each speaker to afford everyone an opportunity to be heard. Equal weight will be given to both oral and written statements. The hearing location is fully accessible to persons with a mobility impairment. Interpreter services shall be made available to deaf persons at no charge upon written request to the Administrative Law Judge (ALJ) at least 10 days prior to the hearing, pursuant to the State Administrative Procedures Act.

Issues Conference: A pre-adjudicatory hearing Issues Conference is scheduled to be held at 10:00 a.m. on February 18, 2003 at the NYS Department of Public Service Hearing Room, One Penn Plaza, 8th Floor, Manhattan, NY. The Issues Conference will continue day to day, as necessary. At the Issues Conference, the ALJ will determine what issues, if any, require adjudication, and will define the scope of such issues. Participation at the Issues Conference will be limited to the DEC Staff, the Applicant and those persons requesting party status pursuant to 6 NYCRR §§624.4 and 624.5. The draft PSD permit conditions referred to above are not subject to an adjudicatory or evidentiary hearing, pursuant to 40 CFR §124.71(c).

Filing for Party Status and Proposed Issues: To participate at the DEC Issues Conference concerning the draft permits identified in this Notice (except the PSD permit), parties must file a written petition requesting party status including the facts intended for presentation pursuant to 6 NYCRR §§624.4(c) and 624.5(b). In addition, any petition must fully identify the proposed party and the name(s) of the person(s) who will act as the party's representative(s), the party's environmental interests, the statutory considerations relevant to the project, whether the request is for full party status or amicus status, and the precise grounds for opposing or supporting the project. Mere opposition to the project is not a sufficient basis to be granted party status. A grant of party status in the parallel Article X proceeding does not automatically grant party status in the DEC hearing process.

If seeking full party status, the petitioner must propose issues that could result in permit denial, major modification of the proposed project, or the imposition of significant permit conditions. The petition must identify all statutory and regulatory requirements which may not be met, and explain why. If a party intends to rely upon expert testimony, the petition must also include an offer of proof that specifies the witness(es), the nature of the arguments, any documentary evidence that the party intends to present at the hearing, and the grounds upon which the assertions are based regarding the proposed issues.

For amicus status, the filing must identify the nature of the legal or policy issues to be briefed, and provide a statement explaining why the proposed amicus is in a special position with respect to those issues.

All petitions must be received by 4:00 p.m. on February 11, 2003 . One copy of any petition requesting either full party status or amicus status must be served upon the following individuals:

  • Administrative Law Judge P. Nicholas Garlick, NYSDEC Office of Hearings and Mediation Services, 625 Broadway, Albany, NY 12233-1550.
