State to hold public hearings on Marcellus Shale wastewater
First meeting set for 5 p.m. today in Cranberry

The Pennsylvania Environmental Quality Board will hold four public hearings this week, the first in Cranberry today, on new state water quality standards aimed at controlling millions of gallons of wastewater pollution produced by burgeoning Marcellus Shale gas drilling.
The state Department of Environmental Protection proposed the new standards which target the discharges of water containing high concentrations of total dissolved solids, or TDS, produced by hundreds of gas drilling operations that use hydraulic fracturing to release the natural gas from the Marcellus Shale, a rock layer located 5,000 to 8,000 feet below the surface beneath two-thirds of the state. Each well can use 4 million to 8 million gallons of water and discharge as much as half that amount. Mine wastewater also can have high TDS levels.
TDS causes toxicity in streams and rivers by increasing salinity, and water analyses of the state's major watersheds show that many rivers and streams have "a very limited ability to assimilate additional TDS, sulfates and chlorides," according to the Pennsylvania Bulletin notice of proposed rulemaking,
Water with high concentrations of TDS has been blamed for creating conditions in Dunkard Creek that killed thousands of fish, mussels and other aquatic life in 43 miles of the stream along the Pennsylvania-West Virginia border, primarily in Greene County. High TDS levels also have affected the taste of public drinking water from companies that draw water from the Monongahela River and caused concern about equipment damage in industries that use water from the river.
The state's rulemaking notice said no treatment exists for TDS, sulfates and chlorides other than dilution, and because of the limited capacity of the state's watersheds to assimilate the TDS loads, "dilution can no longer be considered adequate treatment for high TDS wastewaters."
The goal is to prohibit discharges of new sources of high-TDS wastewater after Jan. 1, 2011.
The hearing in Cranberry is scheduled for 5 p.m. in the Cranberry Township Municipal Building, 2525 Rochester Road.
Other hearings are scheduled for tomorrow at the DEP's Cambria District office, 286 Industrial Park Road, Ebensburg, Cambria County; Wednesday at the DEP Northcentral Regional office, Goddard Conference Room, 208 West Third St., Suite 101, Williamsport, Lycoming County; and Thursday at the Lehigh County Government Center, 17 S. Seventh St. Allentown, Lehigh County. All hearings are at 5 p.m.
The comment period on the proposal closes on Feb. 12.
