Pa. says flow of drilling wastewater almost halted

 HARRISBURG, Pa. – Pennsylvania’s environmental regulators believe that companies drilling in the huge Marcellus Shale natural gas formation have largely stopped taking salty, chemically tainted wastewater to riverside treatment plants that are ill-equipped to remove all the pollutants, an official said Friday.

Department of Environmental Protection spokeswoman Katy Gresh said the agency’s staff has confirmed that the flow of millions of gallons of wastewater has dwindled to possibly just a handful of truck deliveries in the past two weeks. The agency was trying to track those leads down to determine whether the trucks were carrying drilling wastewater, she said.

“We know we have achieved a dramatic sea change here, but we are continuing to verify that we have complete compliance from all the operators all the time,” Gresh said.

The agency had set a May 19 deadline for the companies to voluntarily stop taking drilling wastewater to treatment plants that discharge into rivers – 16 plants, largely in western Pennsylvania. The DEP took the step amid growing concern over harm to drinking water.

Many of the largest drillers have said they have stopped the practice and now either reuse nearly all the wastewater that gushes from gas wells or truck it to Ohio for disposal in that state’s approximately 170 underground injection wells.

Since drilling companies began using high-volume hydraulic fracturing in earnest in 2008 to extract natural gas from the shale, they have taken millions of barrels of the briny waste to treatment plants that discharge into rivers where utilities also draw drinking water for hundreds of thousands, if not millions, of Pennsylvanians.

The state’s April 19 request was made after some researchers presented evidence that the discharges were altering river chemistry in heavily drilled western Pennsylvania in a way that could affect drinking water. The request does not address Pennsylvania’s multitude of coal-fired power plants, shallow-well drillers or other industrial sources that are also a major factor in high salt levels that can affect drinking water.

In the second half of 2010, drillers reported that they generated about 5.4 million barrels of wastewater, and of that brought about 2.8 million barrels to treatment plants that discharge into rivers and streams, about 460,000 barrels to underground disposal wells, and about 2 million barrels to plants that treat the water, but do not discharge into waterways.

The Marcellus Shale formation, considered the nation’s largest-known natural gas reservoir, lies primarily beneath Pennsylvania, New York, West Virginia and Ohio. Pennsylvania is the center of activity, with more than 3,000 wells drilled in the past three years and thousands more planned in the coming years as thick shale emerges as an affordable, plentiful and profitable source of natural gas.
