Firm agrees not to discharge unconventional drilling waste from Marcellus Shale | Shale Energy Insider

Clean Water Action and Waste Treatment Corporation of Warren, Pennsylvania have agreed upon a settlement of a federal lawsuit filed by Clean Water Action in October 2013. Clean Water Action alleged in its lawsuit that WTC violated the Clean Water Act, Endangered Species Act, and the state Clean Streams Law through their continued discharge of up to 200,000 gallons per day of gas drilling wastewater into the Allegheny River in western Pennsylvania.

The settlement requires WTC to install advanced treatment technology in the next 8 months that would remove well over 99% of contaminants in gas drilling wastewater that they are currently discharging (chloride levels would go from about 70,000 mg/L to 200 mg/L).  While the treatment technology is being installed, the company has agreed to not discharge unconventional drilling wastewater, such as from the Marcellus Shale, and will reduce its discharge of conventional drilling wastewater by 35% from permitted levels.

“From the start our goal has been to protect the Allegheny River and the health of people who use it,” said Myron Arnowitt, Pennsylvania State Director for Clean Water Action. “This settlement creates a long lasting solution that will greatly improve our water quality.” The settlement represents the first time an existing industrial treatment plant discharging gas drilling wastewater in Pennsylvania agreed to install effective treatment technology to protect local rivers.
