GRAND JUNCTION, Colo. (AP) - Gov. John Hickenlooper is backing hydraulic fracturing in oil and gas drilling. But he says companies should disclose what chemicals they use in their fracturing fluids.
Hickenlooper made the comments Thursday during a visit to Glenwood Springs. Fracturing fluid is mostly sand and water mixed with chemicals, some of which are toxic. Most companies keep their recipes private. The Daily Sentinel reported that Hickenlooper said drilling in Colorado differs from other states rich in natural gas. Drillers bore far past domestic groundwater supplies where shale protects water from the drilling zone.
Hickenlooper said careless operators can still cause problems and disclosing the fluid's makeup would ease a lot of concerns about the practice. He also supported raising fines for operational errors.
