Any person wishing to comment on the draft EIS may do so. To ensure consideration of your comments on the proposal in the
final EIS, it is important that the Commission receive your comments on or before 5:00 p.m. Eastern Time on May 25, 2026.
Instructions for filing comments are provided on page 4.
FERC is the lead federal agency for authorizing interstate natural gas transmission facilities under the Natural Gas Act of
1938 (NGA) and the lead federal agency for preparation of the draft EIS. The draft EIS 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) (1) and the Commission's implementing regulations. (2) The principal purposes of the draft EIS are to: identify and assess the potential effects on the natural and human environment;
describe and evaluate reasonable alternatives; identify and recommend mitigation measures; and facilitate public involvement
in the environmental review process. The EIS concludes that approval of the proposed Project would have some limited adverse
environmental effects; however, with implementation of the Applicants' avoidance, minimization, and mitigation measures, as
well as adherence to Commission staff's mitigation measures recommended in the EIS, these effects would be less than significant.
The US Army Corps of Engineers, the US Environmental Protection Agency, and the US Fish and Wildlife Service participated
as cooperating agencies in the preparation of the draft EIS. Cooperating agencies have jurisdiction by law or special expertise
with respect to resources potentially affected by the proposal and participate in the NEPA analysis. Although the cooperating
agencies provided input towards the conclusions and recommendations presented in the draft EIS, the agencies will present
their own conclusions and recommendations in their respective records of decision (where applicable) for the Project.
The draft EIS addresses the potential environmental effects of the abandonment, construction, modification, and operation
of the following facilities in Mississippi.
Texas Gas proposes to do the following:
• abandon by sale to Gulf South the existing Greenville Lateral (GL) and axillary and appurtenant facilities; (3) and the existing Isola CS;
- install a new gas-fired compressor unit within the existing Greenville CS totaling 24,160 horsepower (hp); and
modify existing check meters within the Greenville CS to establish custody transfer measurement between Texas Gas and Gulf
South.
Gulf South proposes to do the following:acquire the GL and Isola CS from Texas Gas;
install two new natural gas-fired compressor units totaling 24,615 hp at the Isola CS;
construct two new pipelines: the 8.1-mile-long, 36-inch-diameter Columbia Gulf Lateral and 102.9-mile-long, 36-inch-diameter
Kosciusko Junction (KJ) Pipeline;construct two new compressor stations: the Holmes CS with a natural gas-fired compressor unit totaling 23,984 hp along the
existing GL, and the Kosciusko CS with three natural gas-fired compressor units totaling 61,293 hp along the new KJ Pipeline;
and
• construct four new meter stations: the Columbia Gulf, Destin Check, SONAT, and Kosciusko Meter Stations; (4) four mainline valves; and associated tie-ins, launcher/receiver facilities, and appurtenances.
The Commission mailed a copy of the Notice of Availability of the draft EIS 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 draft EIS 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). In addition, the draft EIS may be accessed by using the eLibrary link on the FERC's website. Click on the eLibrary link
(https://elibrary.ferc.gov/eLibrary/search) select “General Search” and enter the docket number in the “Docket Number” field, excluding the last three digits (i.e., CP25-547 or CP25-549). Be sure you have selected an appropriate date range. For assistance, please contact FERC Online Support
at FercOnlineSupport@ferc.gov or toll free at (866) 208-3676, or for TTY, contact (202) 502-8659.
The draft EIS 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. Under section 7(c) of the NGA,
the Commission determines whether interstate natural gas transportation facilities are in the public convenience and necessity
and, if so, grants a Certificate of Public Convenience and Necessity to construct and operate them. Section 7(b) of the NGA
specifies that no natural gas company shall abandon any portion of its facilities subject to the Commission's jurisdiction
without the Commission first finding that the abandonment will not negatively affect the present or future public convenience
and necessity. The Commission bases its decisions on both economic issues, including need, and environmental effects.
Your comments should focus on draft EIS's disclosure and discussion of potential environmental effects, measures to avoid
or lessen environmental effects, and the completeness of the submitted alternatives, information and analyses. In addition,
landowner comments are encouraged on the site-specific construction plans that the Applicants developed for residences within
25 feet of construction work areas, available via
FERC's eLibrary. [(5)]() For your convenience, there are four methods you can use to submit your comments to the Commission. The Commission encourages

(4) In lieu of sending written or electronic comments, the Commission invites you to attend one of the public comment sessions
its staff will conduct in the Project area to receive comments on the draft EIS, scheduled as follows:
| Date and time | Location |
| --- | --- |
| April 28, 2026, 5:00 p.m. to 7:00 p.m. CDT | The Azalea, 707 Azalea Drive, Waynesboro, MS 39367. |
| April 29, 2026, 5:00 p.m. to 7:00 p.m. CDT | MacMillan Park Center, 515 Hwy. 16 East, Carthage, MS 39051. |
| April 30, 2026, 5:00 p.m. to 7:00 p.m. CDT | City Hall Multipurpose Building, 22521 Depot Street, Lexington, MS 39095. |
The primary goal of these comment sessions is to have you identify the specific environmental issues and concerns with the
draft EIS. Individual oral comments will be taken on a one-on-one basis with a court reporter. This format is designed to
receive the maximum amount of comments, in a convenient way during the timeframe allotted.
Each comment session is scheduled from 5:00 p.m. to 7:00 p.m. (local time zone where meeting is held). You may arrive at any
time after 5:00 p.m. There will not be a formal presentation by Commission staff when the session opens. If you wish to speak,
the Commission staff will hand out numbers in the order of your arrival. Comments will be taken until 7:00 p.m. However, if
no additional numbers have been handed out and all individuals who wish to provide comments have had an opportunity to do
so, staff may conclude the session at 6:30 p.m. Please see appendix 1 for additional information on the session format and
conduct. (6)
Your oral comments will be recorded by the court reporter (with FERC staff or representative present) and become part of the
public record for this proceeding. Transcripts will be publicly available on FERC's eLibrary system (see page 3 for instructions
on using eLibrary). If a significant number of people are interested in providing oral comments in the one-on-one settings,
a time limit of 5 minutes may be implemented for each commentor. Although there will not be a formal presentation, Commission
staff will be available throughout the comment session to answer your questions about the environmental review process.
It is important to note that the Commission provides equal consideration to all comments received, whether filed in written
form or provided orally at a comment session.
Any person seeking to become a party to the proceeding must file a motion to intervene pursuant to Rule 214 of the Commission's
Rules of Practice and Procedures (18 CFR part 385.214). Motions to intervene are more fully described at https://www.ferc.gov/how-intervene. Only intervenors have the right to seek rehearing or judicial review of the Commission's decision. Simply filing environmental
comments will not give you intervenor status, but you do not need intervenor status to have your comments considered.
