On May 12, the United States Environmental Protection Agency (EPA) sent Pennsylvania DEP Secretary Michael Krancer a letter asking “Pennsylvania to do a better job sampling, monitoring and regulating Marcellus Shale wastewater discharges near public drinking water sources.” Specific requests from the EPA included using “stricter public drinking water standards” and enacting “legally enforceable wastewater disposal regulations instead of relying on voluntary actions.” Brine Treatment Corporation in Franklin County, Pa. has not stopped receiving Marcellus waste altogether but is now limiting the amount of Marcellus wastewater it accepts, treats, and discharges into waterways.
