House members say natural gas drilling is safe, but Sen. Casey not so sure

Sen. Bob Casey (D-Pa.), in a letter also sent Tuesday, urged EPA to investigate water contamination in his state from natural gas drilling.

“I have a concern that there isn’t enough of a federal responsibility here,” Casey said. Casey has introduce a bill that would bring fracking under the authority of the Safe Drinking Water Act.

Casey noted a methane leak that polluted drinking water supplies in Susquehanna County as evidence that additional federal oversight is needed.

In the House, Energy and Commerce Chairman Henry Waxman (D-Calif.) and Energy and Environment Subcommittee Chairman Ed Markey (D-Mass.) are investigating the hazards of fracking and if new federal regulations are needed.

The industry says state regs are sufficient.

Ross and Sullivan said EPA oversight would be “burdensome and unnecessary.” They say there is “little to no evidence” the drilling practice poses a threat to water supplies.
