The Pennsylvania Department of Environmental Protection is moving to discourage and, in some cases, ban the use of open waste pits in shale gas operations in favor of closed tanks, in a revised draft of drilling rules that the agency released Monday.
The draft rules would ban waste pits at Marcellus and Utica shale gas well sites, and require companies to close or substantially upgrade large centralized wastewater storage ponds that have leaked and been implicated in soil and water contamination cases in the state in recent years.
