Three companies have applied to develop new coal mines in Utah, Bureau of Land Management spokesman Max Nielson says.

Coastal States Energy, Houston, hopes to develop a mine in Sevier County, adjacent to the company's SUFCO mine, Nielson said."If this one leases, it'll probably be the biggest one we've ever leased" in the BLM region, he said, noting up to 9,900 acres would be leased under Coastal States' application. It is located about six miles west of Emery.

Cyprus-Plateau Mining, Nielson said, wants to open a new mine at the Castle Valley Ridge Tract in Carbon County. The company has another mine near Wattis.

And Beaver County Coal Co. would like to open a new mine on a 765-acre tract adjacent to its Trail Mountain Mine near Orangeville in Emery County, he said.
