On November 3, 2011, the Pennsylvania Department of Environmental Protection ("DEP") announced that it plans to release technical guidance regarding Pennsylvania's updated wastewater treatment regulations, which took effect in August 2010, for new or expanded sources of natural gas wastewater. The guidance will clarify the requirements that facilities accepting shale gas wastewater must meet under the regulations, including effluent standards for total dissolved solids in treated wastewater and radiation monitoring prior to discharge of wastewater that was not fully pre-treated.
