Notice of Availability of the Draft Environmental Impact Statement (DEIS) for the Moxa Arch Area Infill Gas Development Project, Kemmerer, Wyoming.


In accordance with the National Environmental Policy Act (NEPA) of 1969 as amended, and the Federal Land Policy and Management Act of 1976, the Bureau of Land Management (BLM) announces the availability of the Moxa Arch Area Infill Gas Development Project DEIS. The DEIS analyzes the environmental consequences of a proposed natural gas development and production operation on the 475,808 acre Moxa Arch project area.


The DEIS will be available for public review and comment for 60 calendar days starting on the date the Environmental Protection Agency (EPA) publishes their Notice of Availability in the Federal Register. The BLM can best utilize your comments and resource information submissions within the 60-day review period.


A copy of the DEIS has been sent to affected Federal, State, and local government agencies and to interested parties. The document will be available electronically on the following Web site:​wy/​st/​en/​info/​NEPA/​kfodocs/​moxa_​arch.html.

The area is located within the administrative jurisdiction of the BLM Kemmerer Field Office, Townships 15 through 23 North (T15-23N), Ranges 111 through 113 West (R111-113W), 6th Principal Meridian, west of Green River, Wyoming, east of Lyman and Opal, Wyoming, and south of the Green River and Fontenelle Reservoir. Interstate 80 (I-80) bisects the southern third of the Project Area.

EOG Resources, Inc. (EOG) and other companies (Operators) propose to expand the existing natural gas drilling and field development operations on BLM-administered Federal, state, and private lands in the Moxa Arch Area of southwestern Wyoming. The Operators propose to drill up to 1,861 new wells from 1,861 new well pads over a 10-year period. Wells would be drilled to the Frontier and Dakota formations at depths of 11,000 to 12,000 feet. The Life-of-Project is expected to be 40 to 60 years and the wells would be drilled at densities ranging from 4-12 wells per square mile. Of the 1,861 wells, 695 would be drilled from lands administered by the BLM, Bureau of Reclamation, and U.S. Fish and Wildlife Service. The remaining 1,166 wells would be drilled from private lands, or lands administered by the State of Wyoming.

The BLM published its Notice of Intent to prepare an EIS for the Moxa Arch Area Infill Gas Development Project in the Federal Register on October 7, 2005. Based upon issues and concerns identified during scoping and throughout the NEPA process, the Moxa Arch Area Infill Gas Development Project DEIS focuses on potential impacts to air quality, biological and physical resources, transportation, socio-economics, and grazing. In compliance with Section 7(c) of the Endangered Species Act, as amended, the DEIS includes a biological assessment for the purpose of identifying endangered or threatened species, which may be affected by the Proposed Action.

The current identified range of alternatives will allow the BLM to select a management strategy that will meet project objectives, while providing adequate environmental protection. During scoping and alternatives development, few public comments were received. The BLM is seeking additional public input, and has not identified a preferred alternative at this time. The DEIS analyzes four alternatives in detail:

  • The Proposed Action Alternative: The construction of well pads, access roads, pipelines, and other ancillary facilities (gas processing plant, compressor stations, etc.) for projected development of 1,861 natural gas wells;
  • Alternative A (No Action): Development of approximately 757 new wells would continue under the 1997 Record of Decision for the Expanded Moxa Arch Area Natural Gas Development Project EIS;
  • Alternative B: Development would occur as in the Proposed Action, but would apply additional Best Management Practices to reduce impacts on sensitive resources; and
  • Alternative C: Development of 5,165 new wells and well pads throughout the Moxa Arch gas field (densities ranging from 4-16 wells per square mile).
