The Sierra Club testified against Sen. Fran Pavley’s bill to regulate hydraulic fracturing in California at a hearing before the Assembly Appropriations Committee Wednesday, according to the Los Angeles Times.
Pavley's bill, SB 4, would require oil companies to disclose the details of chemicals being used, locations and procedures involved with hydraulic fracturing.
The bill would also require that the Natural Resources Agency commission a scientific study on the safety of fracking to be finished by Jan. 1, 2015. If the study is not completed by the deadline, the issuance of fracking permits would be suspended until it is finished.
The Sierra Club said it opposed the bill, because "it doesn't give the public enough information to protect water and air from potential contamination," the Times reports.
