BLM Worland Seeks Input on Proposed Bentonite Mining Project

The Bureau of Land Management (BLM) Worland Field Office is seeking public comments on a proposed bentonite mining project near Thermopolis, Wyo.

Wyo-Ben, Inc. proposes to conduct new bentonite mining and concurrent reclamation on public land in the Rattlesnake Gulch area located east of Thermopolis in Hot Springs County. Wyo-Ben has been mining in the area since the 1970s and proposes to expand its bentonite mining operations by a maximum of 73 acres. The cast-back mining operation will occur on 10 to 15 acres per year for a proposed 7 to 10 years.

The Worland Field Office will prepare an environmental assessment (EA) to analyze the impacts of the proposed project. The plan of operations submitted by Wyo-Ben is available for review at the Worland Field Office, 101 S. 23rd, Worland, Wyoming. More information including a map of the area can be found on the website at:

Public input is valuable early in the process and will enable the BLM to develop a well-informed EA. This initial public comment period runs from January 20 through February 18, 2011. Comments may be emailed to; please include "Wyo-Ben" in the subject line. Comments may also be mailed to AFM Minerals and Lands, BLM Worland Field Office, P.O. Box 119, Worland, WY 82401.
