Pinedale BLM Hosts Open House and Seeks Comments on Rands Butte Project

The Bureau of Land Management Pinedale Field Office (BLM) is holding an open house and seeking public input for the Rands Butte Draft Environmental Assessment (EA) on support facilities for the new methane and helium recovery facility located west of Big Piney, Wyo.

The open house will be held at the Marbleton Town Hall, 10700 Highway 189, Marbleton, Wyo., from 3:00 7:30 p.m. on, Feb. 11, 2010. Comments are due by close-of-business on Feb. 25, 2010.

The federal components of the project would include constructing: three gas supply wells and the hydrogen sulfide (H2S) and carbon dioxide (CO2) injection well; a 230 kV power line; a natural gas pipeline; a raw helium pipeline; and an ambient air monitoring and weather station.

In 2008, the State of Wyoming granted Cimarex Energy, Inc. a Wyoming Special Use Lease for developing the methane and helium recovery facility located on state lands near Riley Ridge, east of Big Piney, Wyo. The project will test a new technology to process sour gas (a mixture of H2S, CO2, natural gas, and helium). In order to protect human health and reduce greenhouse gas emissions, the H2S/CO2 would be re-injected back into the rock formation. The facility would then provide natural gas and helium to consumers. The project involves approximately 872 acres of state, private, and BLM lands.

Public comments are an important component in the National Environmental Policy Act (NEPA) process. The public is encouraged to participate in the process to help identify issues or concerns not covered in the draft EA, mitigation opportunities, and any other comments or ideas to help ensure the best possible plan. It is especially helpful to have written comments.

For more information please contact Bill Lanning at: 307-367-5318. The complete draft EA is available online at:

The BLM manages more land - 253 million acres - than any other Federal agency. This land, known as the National System of Public Lands, is primarily located in 12 Western states, including Alaska. The Bureau, with a budget of about $1 billion, also administers 700 million acres of sub-surface mineral estate throughout the nation. The BLM's multiple-use mission is to sustain the health and productivity of the public lands for the use and enjoyment of present and future generations. The Bureau accomplishes this by managing such activities as outdoor recreation, livestock grazing, mineral development, and energy production, and by conserving natural, historical, cultural, and other resources on public lands.
