DEPARTMENT OF ENERGY
Federal Energy Regulatory Commission
[Docket No. CP26-2-000]
Enable Mississippi River Transmission, LLC; Notice of Schedule
for the Preparation of an Environmental Assessment for the Ameren-EMRT
Big Hollow Project
On October 6, 2025, Enable Mississippi River Transmission, LLC
(EMRT) filed an application in Docket No. CP26-2-000 requesting a
Certificate of Public Convenience and Necessity pursuant to Section
7(c) of the Natural Gas Act to construct and operate certain natural
gas pipeline facilities in Monroe County, Illinois and Jefferson
County, Missouri. The proposed project is known as the Ameren-EMRT Big
Hollow Project (Project) and would provide about 200,000 million
standard cubic feet per day of transportation capacity to the Union
Electric Company's d/b/a Ameren Missouri's (Ameren) new gas-fired
electric generating plant at the Big Hollow Energy Center on the site
of their retired Rush Island coal-fired Energy Center.
On October 15, 2025, the Federal Energy Regulatory Commission
(Commission or FERC) issued its Notice of Application for the Project.
Among other things, that notice alerted agencies issuing federal
authorizations of the requirement to complete all necessary reviews and
to reach a final decision on a request for a federal authorization
within 90 days of the date of issuance of the Commission staff's
environmental document for the Project.
This notice identifies Commission staff's intention to prepare an
environmental assessment (EA) for the Project and the planned schedule
for the completion of the environmental review.\1\ The EA will be
issued for a 30-day comment period.
---------------------------------------------------------------------------
\1\ For tracking purposes under the National Environmental
Policy Act, the unique identification number for documents relating
to this environmental review is EAXX-019-20-000-1763644926.
---------------------------------------------------------------------------
Schedule for Environmental Review
Issuance of EA--April 10, 2026
90-day Federal Authorization Decision Deadline \2\--July 9, 2026
---------------------------------------------------------------------------
\2\ The Commission's deadline applies to the decisions of other
federal agencies, and state agencies acting under federally
delegated authority, that are responsible for federal
authorizations, permits, and other approvals necessary for proposed
projects under the Natural Gas Act. Per 18 CFR 157.22(a), the
Commission's deadline for other agency's decisions applies unless a
schedule is otherwise established by federal law.
If a schedule change becomes necessary, additional notice will be
provided so that the relevant agencies are kept informed of the
Project's progress.
Project Description
The Project includes construction and operation of a lateral
pipeline, measurement and regulation station, and appurtenant
facilities to facilitate Union Electric Company's d/b/a Ameren
Missouri's (Ameren) new gas-fired electric generating plant at the Big
Hollow Energy Center on the site of their retired Rush Island coal-
fired Energy Center.
The Ameren-EMRT Big Hollow Project would consist of the following
facilities:
<bullet> an approximate 9.6-mile-long, 20-inch-diameter lateral
pipeline, from a point of interconnection on EMRT's existing 22-inch-
diameter Mainline 2 and 26-inch-diameter Mainline 3 pipelines, at Mile
Post 415.5 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, including a 20-inch pig
launcher, 20-inch pig receiver, and 20-inch hot taps on existing
Mainline 2 and 3 at the lateral interconnect locations.
Background
On October 21, 2025, the Commission issued a Notice of Scoping
Period Requesting Comments on Environmental Issues for the Proposed
Ameren-EMRT Big Hollow Project (Notice of Scoping). The Notice of
Scoping was sent to affected landowners; federal, state, and local
government agencies; elected officials; environmental and public
interest groups; Native American tribes; other interested parties; and
local libraries. In response to the Notice of Scoping, the Commission
received comments from the Illinois Department of Natural Resources and
two landowners. The primary issues raised by the commenters are air
emissions and noise, and potential impacts to Illinois Nature Preserve
Commission-protected lands within the Project vicinity. All substantive
comments will be addressed in the EA.
