We are subject to federal, state and local regulations regarding air and water quality, hazardous and solid waste disposal and other environmental matters. During the third quarter of 2015, the West Virginia Department of Environmental Protection issued us a Notice of Violation for improper installation of an engine. We do not expect that any ultimate sanction will have a material impact on our financial position, results of operations, or liquidity.
The entire disclosure for commitments and contingencies.
