Iroquois Enhancement by Compression (ExC) Project

DEC Application IDs:

3-1326-00211/00001 (Dover Compressor Station)
4-1922-00049/00004 (Athens Compressor Station)

Permit(s) Applied for:

Article 19, Air State Facility

Project Locations:

Dover Compressor Station, 186 Dover Furnace Road (Co. Route 46), Dover Plains, NY 12522
Athens Compressor Station, 915 Schoharie Turnpike (Co. Route 28), Athens, NY 12015

Project Description:

The Iroquois Enhancement by Compression Project (ExC Project) includes the addition of 12,000 horsepower (hp) of new compression and associated facilities at the existing Iroquois Dover Compressor Station located at 186 Dover Furnace Road in Dover Plains and the addition of 12,000 hp of new compression and associated facilities at the existing Iroquois Athens Compressor Station located at 915 Schoharie Turnpike in Athens. The ExC Project also includes upgrades at the Milford and Brookfield Stations in Connecticut. The ExC Project is designed to provide a total of 125,000 Dekatherms per day (Dth/d) of incremental firm natural gas transportation service to two existing customers of Iroquois, Consolidated Edison Company of New York, Inc. (Con Ed) and KeySpan Gas East Corporation d/b/a National Grid (National Grid).

Air State Facility (ASF) Applications:

New York State Department of Environmental Conservation (NYS DEC) has prepared draft permits and has made a tentative determination, subject to public comment or other information, to approve Air State Facility (ASF) permit modifications for both New York facilities included in the ExC Project. With respect to air pollution regulation, the activities of concern at the Dover and Athens Compressor Stations are emissions of criteria contaminants which are produced from the operation of the stationary combustion turbines used to compress the natural gas in the pipeline operated by Iroquois. Control measures include low NOx combustion technology and oxidation catalysts.

Pursuant to the requirements of Section 7(2) of the Climate Leadership and Community Protection Act (Climate Act), Chapter 106 of the Laws of 2019, NYS DEC has requested and received information regarding the ExC Project's consistency with the Climate Act. The ExC Project includes the installation of GHG mitigation measures, including Vent Recovery Systems (VRS) at each of the four Project compressor stations in NYS and CT, and fuel use restrictions limiting the maximum operation of each new turbine. Iroquois also proposed the installation of VRS, if feasible, at each of three other (i.e., non-Project) compressor stations located in NYS (Boonville, Croghan, and Wright) as additional GHG mitigation. These have been incorporated into the draft ASF permits and would be included, along with any other GHG mitigation measures as appropriate, as part of any ASF permits ultimately issued by NYS DEC, provided that the other elements of Section 7(2) can be met.

Pursuant to Section 7(3) of the Climate Act, NYS DEC and other agencies must ensure that its permitting and other administrative decisions do not disproportionately burden Disadvantaged Communities. NYS DEC has requested and received information from Iroquois regarding the ExC Project's potential impact on Disadvantaged Communities, as identified pursuant to the Climate Act. The Athens Compressor Station is in and has the potential to impact a draft Disadvantaged Community. Additionally, the Dover Compressor Station is immediately adjacent to and has the potential to impact a draft Disadvantaged Community. Therefore, at NYS DEC's request, Iroquois provided a Disadvantaged Communities (DAC) Evaluation for the ExC Project. While Iroquois asserts that the ExC Project would not disproportionately burden any Disadvantaged Communities, NYS DEC has not yet made a final determination. Prior to issuing any permits for the Facility, NYS DEC would need to ensure compliance with the requirements of Climate Act Section 7(3).

While NYS DEC is making draft Air State Facility permits available for public review and comment, NYS DEC has not made any final determination to issue any final permits for the Facility. Prior to issuing any final permits for the Facility, NYS DEC would need to ensure that it can meet the requirements of both Section 7(2) and Section 7(3) of the Climate Act. NYS DEC has yet to make either determination. NYS DEC may seek additional information from the Applicant to facilitate making these legally required determinations.

National Environmental Policy Act (NEPA) Determination:

The Federal Energy Regulatory Commission (FERC) is the lead agency for the environmental review of interstate natural gas facilities under the federal Natural Gas Act. FERC staff prepared a Final Environmental Impact Statement (Final EIS), dated November 12, 2021, for the ExC Project, Docket No. CP20-48-000, pursuant to NEPA. The FERC Final EIS can be viewed and downloaded at: by entering the Docket No. and the date of the Final EIS in the search boxes.

The federal environmental review process conducted by FERC pursuant to NEPA takes the place of an environmental review conducted under the State Environmental Quality Review Act. NYS DEC evaluates the FERC NEPA documents and the permit applications submitted by applicants to NYS DEC to ultimately make a determination regarding issuance of NYS DEC authorizations.

State Environmental Quality Review (SEQR) Determination:

This project is not subject to SEQR (federally preempted) and therefore is treated as if it was a Type II action. SEQR Lead Agency: None Designated

State Historic Preservation Act (SHPA) Determination:

The proposed activity is not subject to review in accordance with SHPA. The activity is being reviewed in accordance with federal historic preservation laws (Section 106 of NHPA) and the project area of potential impact is substantially the same.

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.

Statutory and Regulatory Provisions:

The above referenced applications were filed and reviewed pursuant to Environmental Conservation Law (ECL) Article 3, Title 3 (General Functions, Powers, Duties and Jurisdiction), and Article 70 (Uniform Procedures Act or UPA); and pursuant to Title 6 of Official Compilation of Codes, Rules and Regulations of the State of New York (6 NYCRR) Part 621- Uniform Procedures. The relevant regulations are found at: Part 201 (Air State Facility).
