Could be new fracking rules in Colorado

DENVER (AP) - Some Colorado counties want changes in a proposed state rule that would require oil and gas companies to publicly disclose most of the chemicals they use in hydraulic fracturing.

Hydraulic fracturing, or fracking, involves blasting water, sand and chemicals into rock formations so oil and natural gas can escape.

The Colorado Oil and Gas Conservation Commission has proposed requiring companies to publicly disclose their fracking chemicals, but ingredients considered to be a "trade secret" would be disclosed only to state regulators and certain county officials and health professionals on request.

Delta County commissioners have suggested clarifying how operators declare something to be a trade secret, while Pitkin County commissioners are pushing for public disclosure of all chemicals.

A public hearing on the proposed rule is scheduled for Dec. 5.
