FLEMINGTON, W.Va. -- A contractor has identified an employee who was killed in an explosion at an EQT natural gas well pad in Taylor County. Central Environmental Services CEO Jeff Harper tells WBOY-TV that Brian Hopkins was near two tanks when the explosion occurred on Friday. The state Department of Environmental Protection has said the worker was attempting to transfer briny wastewater from a tank into a truck. Harper says Hopkins hadn't begun transferring water when the explosion occurred. He says the transfer is a routine activity that the company's employees do every day. Harper says CES is cooperating with state and federal investigators. The company also is conducting an internal investigation. EQT spokeswoman Linda Robertson has said the accident wasn't related to drilling.
