Texas Eastern Transmission, L.P.; Notice of Availability of the Environmental Assessment for the Proposed Perulack Compressor Units Replacement Project

The staff of the Federal Energy Regulatory Commission (FERC or Commission) has prepared an environmental assessment (EA) for the Perulack Compressor Units Replacement Project, proposed by Texas Eastern Transmission, LP (Texas Eastern) in the above-referenced docket. Texas Eastern requests authorization to replace four existing natural gas-fired turbine compressor engines with two new units and appurtenant facilities at its existing Perulack Compressor Station in Juniata County, Pennsylvania.

The EA assesses the potential environmental effects of the construction and operation of the Perulack Compressor Units Replacement Project in accordance with the requirements of the National Environmental Policy Act. 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 project includes the following facilities:

• Two new 18,100-horsepower (hp) Solar Titan 130 natural gas-fired turbines;
• related software controls that would limit the total hp of each compressor unit to 17,400 hp to be consistent with current certificated capacity of the compressor station of 34,800 hp;
• one new 585-hp Waukesha VGF-H24GL emergency generator;
• a new compressor building to house the two new compressor units;
• conversion of an existing compressor building into a storage warehouse;
• a new service entry building, two new electric buildings, two natural gas-fired heaters, two space heaters, four new filter/separator vessels, and six new gas coolers;
• a new stormwater management retention basin; and

Removal of four natural gas fired centrifugal turbine compressor units and the associated auxiliary piping and equipment and two generators.

The Commission mailed a copy of the Notice of Availability to federal, state, and local government representatives and agencies; elected officials; 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 ( www.ferc.gov ), on the natural gas environmental documents page ( https://www.ferc.gov/industries-data/natural-gas/environment/environmental-documents ).

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 Commission 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 July 5, 2021.

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.
