DEPARTMENT OF ENERGY
Federal Energy Regulatory Commission
[Docket No. CP26-2-000]
Enable Mississippi River Transmission, LLC; Notice of
Availability of the Environmental Assessment for the Proposed Ameren--
Emrt Big Hollow Project
The staff of the Federal Energy Regulatory Commission (FERC or
Commission) has prepared an environmental assessment (EA) for the
Ameren--EMRT Big Hollow Project, proposed by Enable Mississippi River
Transmission, LLC (EMRT) in the above-referenced docket.\1\ EMRT
requests authorization to construct and operate certain natural gas
pipeline and appurtenant facilities in Monroe and Jefferson counties in
the states of Illinois and Missouri. EMRT states the project purpose is
to provide about 200,000 million standard cubic feet of natural gas per
day to Ameren's Big Hollow Energy Center to facilitate the new gas-
fired generation at the site of their retired Rush Island Energy
Center.
---------------------------------------------------------------------------
\1\ For tracking purposes under the National Environmental
Policy Act, the unique identification number for documents relating
to this environmental review is EAXX-019-20-000-1739964549
---------------------------------------------------------------------------
Any person wishing to comment on the EA may do so. To ensure
consideration of your comments on the proposal prior to making a
decision on the project, it is important that the Commission receive
your comments on or before 5:00 p.m. Eastern Time on May 11, 2026.
Instructions for filing comments are provided on page 3.
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 EA. The EA assesses the
potential environmental effects of the Ameren--EMRT Big Hollow Project
in accordance with the requirements of the National Environmental
Policy Act (NEPA) \2\ and the Commission's implementing regulations.\3\
The principal purposes of the EA 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 EA concludes that approval of the proposed project would
not constitute a major federal action significantly affecting the
quality of the human environment.
---------------------------------------------------------------------------
\2\ National Environmental Policy Act of 1969, as amended
(Public Law [Pub. L.] 91-190. 42 U.S.C. 4321-4347, as amended by
Pub. L. 94-52, July 3, 1975; Pub. L. 94-83, August 9, 1975; Pub. L.
97-258, 4(b), September 13, 1982; Pub. L. 118-5, June 3, 2023; Pub.
L. 119-21, July 4, 2025).
\3\ 18 Code of Federal Regulations (CFR) 380.
---------------------------------------------------------------------------
The EA addresses the potential environmental effects of the
construction and operation of the following project facilities:
<bullet> an approximate 9.6-mile-long, 20-inch-diameter lateral
pipeline, from a point of interconnection on EMRT's existing mainlines
in Monroe County, Illinois to the existing Big Hollow Energy Center
site in Jefferson County, Missouri;
<bullet> a measurement and regulation station located downstream of
the tie-in with Ameren's proposed Big Hollow Energy Center; and
<bullet> appurtenant pipeline facilities.
The Commission mailed a copy of the Notice of Availability of the
EA 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 libraries in the project area.
The EA is only available in electronic format. It may be viewed and
downloaded from the FERC's website (<a href="http://www.ferc.gov">www.ferc.gov</a>), on the natural gas
environmental documents page (<a href="https://www.ferc.gov/industries-data/natural-gas/environment/environmental-documents">https://www.ferc.gov/industries-data/natural-gas/environment/environmental-documents</a>). In addition, the EA
may be accessed by using the eLibrary link on the FERC's website. Click
on the eLibrary link (<a href="https://elibrary.ferc.gov/eLibrary/search">https://elibrary.ferc.gov/eLibrary/search</a>),

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.
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. The Commission
bases its decisions on both economic issues, including need, and
environmental effects.
Your comments should focus on the EA's disclosure and discussion of
potential environmental effects, reasonable alternatives, and measures
to avoid or lessen environmental effects. The more specific your
comments, the more useful they will be. For your convenience, there are
three methods you can use to file your comments to the Commission. The
Commission encourages electronic filing of comments and has staff
available to assist you at (866) 208-3676 or
<a href="/cdn-cgi/l/email-protection#95d3f0e7f6dafbf9fcfbf0c6e0e5e5fae7e1d5f3f0e7f6bbf2fae3"><span class="__cf_email__" data-cfemail="8bcdeef9e8c4e5e7e2e5eed8fefbfbe4f9ffcbedeef9e8a5ece4fd">[email protected]</span></a>. Please carefully follow these instructions
so that your comments are properly recorded.
(1) You can file your comments electronically using the eComment
feature on the Commission's website (<a href="http://www.ferc.gov">www.ferc.gov</a>) under the link to
FERC Online. This is an easy method for submitting brief, text-only
comments on a project;
(2) You can also file your comments electronically using the
eFiling feature on the Commission's website (<a href="http://www.ferc.gov">www.ferc.gov</a>) under the

Regulatory Commission, 888 First Street NE, Room 1A, Washington, DC
20426. Submissions sent via any other carrier must be addressed to:

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.
Motions to intervene are more fully described at <a href="https://www.ferc.gov/how-intervene">https://www.ferc.gov/how-intervene</a>.
