A Halliburton Co. subsidiary will pay $1.8 million in state fines for violating Pennsylvania's Solid Waste Management Act, but it will not face criminal charges as some had called for in 2012, according to the Pennsylvania Attorney General'soffice. Halliburton Energy Services signed an agreement saying it would pay the Pennsylvania Department of Environmental Protection's (DEP) fine and not appeal the agency’s findings (see Shale Daily, Feb. 20). The DEP cited Halliburton for committing 255 violations related to the treatment, storage and disposal of drilling waste at its facility in Indiana County, PA. The DEP asked the attorney general's office to conduct a criminal investigation last year, but a spokesman for Attorney General Kathleen Kane said the office's review showed no cause for such action. No further explanation was offered. Environmental groups had also pushed for a criminal investigation. The attorney general's latest decision marks the second time the office has decided not to pursue criminal charges since the DEP learned of the violations in 2011.
