Federal Energy Regulatory Commission

[Docket No. CP18-11-000]

East Cheyenne Gas Storage, LLC; Notice of Schedule for 
Environmental Review of the Lewis Creek Amendment

    On October 27, 2017, East Cheyenne Gas Storage, LLC (East Cheyenne) 
filed an application in Docket No. CP18-11-000 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. The proposed project, known as the Lewis Creek Amendment 
Project (Project), would combine the working gas capacity and cushion 
gas capacity for the West Peetz and Lewis Creek Storage Fields and 
utilize the same maximum bottom-hole pressure, thus eliminating 
separately certified capacities for each field. East Cheyenne requests 
this amendment because recent geologic information shows that the West 
Peetz and Lewis Creek D-sands in the storage field are a single 
integrated reservoir. As part of this consolidation, East Cheyenne 
would reconfigure certain natural gas facilities in the Lewis Creek 
Storage Field; and expand the authorized buffer zone of the East 
Cheyenne Project.
    On November 8, 2017, 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 Assessment (EA) for the Project. This instant notice 
identifies the FERC staff's planned schedule for the completion of the 
EA for the Project.

Schedule for Environmental Review

    Issuance of EA, March 30, 2018.
    90-day Federal Authorization Decision Deadline, June 28, 2018.
    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

    East Cheyenne is requesting authorization to amend its certificate 
previously issued in Docket No. CP10-34-000, for the East Cheyenne Gas 
Storage Project in Logan County, Colorado. As part of the West Peetz 
and Lewis Creek Field consolidation, East Cheyenne would reconfigure 
the well layout on the Lewis Creek portion of the Project by reducing 
the number of injection/withdrawal (I/W) wells by consolidating the 
wells on a single well pad, and reconfiguring the currently 
certificated Lewis Creek monitoring wells. Specifically, East Cheyenne 
would reconfigure the I/W well in the Lewis Creek portion of the 
project by converting one existing non-jurisdictional well to an I/W 
well (LC-D021) and collocating five directionally drilled I/W wells 
(LC-D022, LC-D023, LC-D024, LC-D025, and LC-D026) on the LC-2021 well 
pad. Additionally, East Cheyenne would decrease the total cushion gas 
capacity to 12.1 billion cubic feet and increase the total working gas 
capacity to 22.5 billion cubic feet. East Cheyenne would also 
reconfigure its existing pipelines and reduce the diameter of the 
existing 20-inch-diameter natural gas mainline to a 16-inch-diameter 
pipeline. Furthermore, East Cheyenne would reconfigure the existing 16-
inch diameter Lewis Creek natural gas mainline and the 6-inch-diameter 
water disposal pipeline to connect directly to the reconfigured I/W 
wells LC-D021 through LC-D026 on a single well pad.


    On December 8, 2017, the Commission issued a Notice of Intent to 
Prepare an Environmental Assessment for the Proposed Lewis Creek 
Amendment and Request for Comments on Environmental Issues (NOI). The 
NOI 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 and newspapers. In response to the NOI, the Commission 
received comments from the Bureau of Land Management and the Logan 
County Economic Development Corporation support the applicant's
