"Two chemical manufacturers are seeking an exemption from new rules in Wyoming that require public disclosure of the chemicals used in hydraulic fracturing, a controversial natural gas drilling process suspected of polluting groundwater.
ChemEOR, based in Covina, Calif., and CESI Chemical Inc., based in Marlow, Okla., have asked the Wyoming Oil and Gas Conservation Commission to grant their fracturing fluids trade secret status, according to state oil and gas supervisor Tom Doll. The designation would still require the companies to share their formulas with the state but would exempt them from making the information available to the public."
