Start Preamble

On October 9, 2020, Spire Storage West, LLC (Spire Storage) filed an application in Docket No. CP21-6-000 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 is known as the Clear Creek Expansion Project (Project), and would expand Spire Storage's natural gas storage facilities in Uinta County, Wyoming in order to increase the certificated gas capacities from 4.0 billion cubic feet (Bcf) to 20 Bcf, and increase the maximum daily injection and withdrawal capacities from 35 million cubic feet (MMcf) and 50 MMcf per day, to 350 MMcf and 500 MMcf per day, respectively.

On October 22, 2020, 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]

Schedule for Environmental Review

Issuance of EA May 13, 2021

90-day Federal Authorization Decision Deadline August 11, 2021

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 Clear Creek Expansion Project would consist of the following facilities in Uinta County, Wyoming:

  • Four compressor units at the Clear Creek Plant;
  • a tank storage and natural gas liquids fueling equipment facility on an existing pad;
  • 11 new injection/withdrawal wells, one new water disposal well, and associated lines;
  • approximately 10.6 miles of 20-inch-diameter pipeline;
  • approximately 3.5 miles of 4,160-volt powerline; and
  • other related appurtenances.


On November 9, 2020, the Commission issued a Notice of Scoping Period Requesting Comments on Environmental Issues for the Proposed Clear Creek Expansion 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 and newspapers. In response to the Notice of Scoping, the Commission received comments from the Wyoming Department of Environmental Quality. The primary issues raised by the commenter are permitting, stream crossings, wetland impacts, and spill reporting. All substantive comments will be addressed in the EA.

The U.S. Bureau of Land Management is a cooperating agency in the preparation of the EA.
