Even though the federal government is tightening up on the mining industry, an arch coal subsidiary is getting a surface mine permit.

The U.S. Army Corps of Engineers will allow Coal Mac to operate its Pine Creek No. 1 surface mine in Logan county.

To mitigate the mine's effects, Coal Mac must restore and enhance more than 60,000 feet of streams and more than 70 acres of forests near the operation.

The U.S. Environmental Protection Agency says the permit complies with its new effort to reduce environmental harm caused by mountaintop removal mines in Appalachia.
