From the Colorado Independent (David O. Williams):
DeGette, who last summer introduced the Fracturing Responsibility and Awareness of Chemicals (FRAC) Act, has been trying to remove a Safe Drinking Water Act exemption for hydraulic fracturing – a processed used by oil and gas companies – that was granted in 2005 during the Bush administration.
Dubbed the “Halliburton Loophole” for the oil and gas drilling services company that perfected hydraulic fracturing, or “fracking,” the 2005 exemption allows companies to keep secret the chemicals injected deep into natural gas wells, along with water and sand, to fracture tight geological formations and free up more gas.
Industry officials claim the process has been used for decades with no known cases of groundwater contamination and that the chemical formulas are proprietary. Environmentalists, some residents of energy producing area and an increasing number of politicians say the process is tainting drinking water and needs to be more closely regulated.
