BLM Seeks Input on Proposed Multi-County Seismic Survey


The Bureau of Land Management (BLM) is seeking input on a proposed seismic survey on public lands within portions of Big Horn, Natrona, Park and Washakie counties. The University of Texas at El Paso (UTEP), as part of the National Science Foundation EarthScope Program, has applied for authorization to conduct seismic imaging in order to understand the mechanisms of formation of the Rocky Mountains.

The proposed project would space seismic shot points at intervals of 20 to 50 miles along a line from 30 miles northwest of Casper, Wyo. to 10 miles north of Lovell, Wyo. A second shot point line would run from 4 miles south of Cody, Wyo. to 25 miles east of Greybull, Wyo. Detonation may be felt a few hundred yards from the shot point, producing a sound similar to muffled thunder. The proposed shot points and seismic recorders would be located in quarries and borrow pits along rights of way for County, State and Federal roads and mapped two-tracks where new surface disturbance would be minimized. Work is proposed to commence in the summer of 2010 and be completed within two to three months.

The BLM will prepare an environmental assessment (EA) to analyze UTEP's proposed project. A scoping notice and map of the proposed project area are posted on the website at: http://www.blm.gov/wy/st/en/info/NEPA/wfodocs/utep.html.

Public input is valuable early in the process and will enable the BLM to develop a well-informed EA. Comments should be postmarked by May 1, 2010. Written comments may be emailed to: BighornDeepStructure_WY@blm.gov or addressed to: UTEP Bighorn Deep Structure EA, BLM Worland Field Office, P.O. Box 119, Worland, WY 82401.

For more information, please contact Andrew Tkach at 307-347-5100 or at the email address above.



The BLM manages more than 245 million acres of public land, the most of any Federal agency. This land, known as the National System of Public Lands, is primarily located in 12 Western states, including Alaska. The BLM also administers 700 million acres of sub-surface mineral estate throughout the nation. The BLM's mission is to manage and conserve the public lands for the use and enjoyment of present and future generations under our mandate of multiple-use and sustained yield. In Fiscal Year 2013, the BLM generated $4.7 billion in receipts from public lands.
