Pennsylvania Gov. Tom Wolf has signed into law a bill that will limit liabilities for any oil and natural gas producer in that state uses treated coal mine water to drill and stimulate its wells. SB 875 passed the state Senate by a vote of 34-15 in June, and it was passed by a vote of 160-37 last month (see Shale Daily, Oct. 1). After the House signed it, Wolf's administration said he would support it. The legislation clarifies the legal liabilities associated with the use of treated mine water in oil and gas operations. It's aimed at reducing the use of fresh water for drilling and completion operations. Without the legislation, its sponsors have said, legal liabilities have been a deterrent to more producers using the treated water in their wells (see Shale Daily, June 5).
