Colorado approves disclosure of fracking chemicalsColo. will require energy companies to publicly disclose concentrations of fracking chemicals
DENVER (AP) ' Colorado will require energy companies to disclose the concentrations of all chemicals in hydraulic fracturing and also ask drillers to make public some information about ingredients considered trade secrets.
Colorado regulators unanimously approved the new rules Tuesday that take effect in April.
The guidelines are similar to those required by a first-in-the-nation law passed in Texas this year but go further by requiring the concentrations of chemicals to be disclosed. Also, if Colorado drillers claim a trade secret, they would still have to disclose the ingredient's chemical family. In emergencies, companies would have to tell health care workers what those secret ingredients were.
Companies have been fracking for decades, but as drilling expands to more populated areas, residents near wells are concerned about effects on their health and drinking water.
