GILLETTE, Wyo. (AP) — The U.S. Bureau of Land Management is planning to hold a lease sale for an estimated 167 million tons of coal in Wyoming's Powder River Basin.

The BLM says in its Aug. 8 notice the 1,250-acre Hay Creek II Coal Tract sale is being held in response to an application filed by Kiewit Mining Properties Inc. subsidiary Buckskin Mining Co.

Kiewit owns most of the 1,250-acre tract's surface estate, which is located 12 miles north of Gillette.
The coal lease sale is set for Sept. 18, with sealed bids accepted until the day before. The minimum bid is $100 per acre.

The BLM is taking comment on the proposed sale until Sept. 17.
