Wyo-Ben Proposal to Expand Bentonite Mine Now Available for Public Review

BILLINGS, MT --- The preliminary environmental assessment for Wyo-Ben Inc.’s proposal to amend its bentonite mine plan is now available for public review.

Wyo-Ben Inc. submitted a Plan of Operations amendment to the Bureau of Land Management Billings Field Office and the Montana Department of Environmental Quality to amend its mine plan for bentonite mining in Carbon County, just east of Montana State Route 310. Amendment No. 2 proposes to increase the permit area by 940 acres of BLM-managed land. Surface disturbance would not be authorized on all land within the permit boundary.

The BLM has analyzed the potential environmental impacts of the mine expansion proposal and is now seeking public comment. Written comments will be accepted until March 12, 2014. Following the 30-day comment period, the BLM and MDEQ will consider all comments received and then make separate decisions whether or not to approve the proposed action identified in the environmental assessment.

The document may be requested from the BLM Billings Field Office or accessed via the web at:

Comments may be submitted by email at:, or by regular mail to: BLM Billings Field Office, Attn: Craig Drake, 5001 Southgate Dr., Billings, MT 59101.

Those providing comments are advised that before including address, phone number, e-mail address, or other personal identifying information, that their entire comment – including personal identifying information – may be made publicly available at any time. While those commenting can ask in their comments to withhold personal identifying information from public review, the BLM cannot guarantee that they will be able to do so.
