W.Va. DEP fines Michels for drilling mud pollution by San Francisco Chronicle, February 13, 2013
A pipeline construction company that West Virginia regulators say polluted a stream must pay a $3,800 fine and stop storing mud from gas drilling operations at its site near Lumberton. … The DEP says inspectors discovered last fall that Michels had put drilling mud from an Antero Resources operation into an unlined waste pit. … Michels admits no wrongdoing in the agreement but says it will comply with state law going forward.
