Start Preamble

The staff of the Federal Energy Regulatory Commission (FERC or Commission) has prepared an environmental assessment (EA) for the Enhancement by Compression Project (Project), proposed by Iroquois Gas Transmission, L.P. (Iroquois) in the above-referenced docket. Iroquois requests authorization to construct and operate natural gas transmission facilities in New York and Connecticut. The Project is designed to provide a total of 125,000 Dekatherms per day [1] of incremental firm transportation service to two existing customers of Iroquois, Consolidated Edison Company of New York, Inc. and KeySpan Gas East Corporation doing business as National Grid.

The EA assesses the potential environmental effects of the construction and operation of the Project in accordance with the requirements of the National Environmental Policy Act (NEPA). The FERC staff concludes that approval of the proposed Project, with appropriate mitigating measures, would not constitute a major federal action significantly affecting the quality of the human environment.

The proposed Project includes the following facilities:

  • Athens Compressor Station—installation of one new 12,000 horsepower (hp) turbine (Unit A2) in a new building with associated cooling, filter separators, and other appurtenant facilities, within the existing fenced boundary (Greene County, New York).
  • Dover Compressor Station—installation of one new 12,000 hp turbine (Unit A2) in a new building with associated cooling, filter separators, appurtenant facilities, and expansion of the existing fenceline within the property boundary (Dutchess County, New York).
  • Brookfield Compressor Station—construction of a control/office building, and addition of two new 12,000 hp turbines (Unit B1 and Unit B2) in a new building with associated cooling, filter separators, and other appurtenant facilities. Additionally, Iroquois would install incremental cooling at Plant 2-A to allow natural gas to be cooled, prior to being compressed at the proposed downstream compressors (Units B1 and B2). Iroquois would also replace turbine stacks on the existing compressor units (Unit-A1 and Unit-A2) and add other noise reduction measures (e.g., louvers, seals) to minimize existing noise at the site. Modifications at this site would require expansion of the existing fenceline within the property boundary (Fairfield County, Connecticut).
  • Milford Compressor Station—addition of gas cooling to existing compressor units and associated piping, within the existing fenced boundary (New Haven County, Connecticut).

The Commission mailed a copy of the Notice of Availability to federal, state, and local government representatives and agencies; elected officials; environmental and public interest groups; Native American tribes; potentially affected landowners and other interested individuals and groups; and newspapers and libraries in the Project area. The EA is only available in electronic format. It may be viewed and downloaded from the FERC's website (, on the natural gas environmental documents page (​industries-data/​natural-gas/​environment/​environmental-documents). In addition, the EA may be accessed by using the eLibrary link on the FERC's website. Click on the eLibrary link (​eLibrary/​search), select General Search and enter the docket number in the Docket Number field, excluding the last three digits (i.e. CP20-48).

The EA is not a decision document. It presents Commission staff's independent analysis of the environmental issues for the Commission to consider when addressing the merits of all issues in this proceeding. Any person wishing to comment on the EA may do so. Your comments should focus on the EA's disclosure and discussion of potential environmental effects, reasonable alternatives, and measures to avoid or lessen environmental impacts. The more specific your comments, the more useful they will be. To ensure that the Start Printed Page 63109Commission has the opportunity to consider your comments prior to making its decision on this Project, it is important that we receive your comments in Washington, DC on or before 5:00 p.m. Eastern Time on October 30, 2020.

Submissions sent via any other carrier must be addressed to: Kimberly D. Bose, Secretary, Federal Energy Regulatory Commission, 12225 Wilkins Avenue, Rockville, Maryland 20852.

Filing environmental comments will not give you intervenor status, but you do not need intervenor status to have your comments considered. Only intervenors have the right to seek rehearing or judicial review of the Commission's decision. At this point in this proceeding, the timeframe for filing timely intervention requests has expired. Any person seeking to become a party to the proceeding must file a motion to intervene out-of-time pursuant to Rule 214(b)(3) and (d) of the Commission's Rules of Practice and Procedures (18 CFR 385.214(b)(3) and (d)) and show good cause why the time limitation should be waived.
