Colorado regulators have approved new rules requiring energy companies to publicly disclose chemicals used in hydraulic fracturing but allowing them to protect trade secrets.
The Colorado Oil and Gas Conservation Commission unanimously approved the rules Tuesday.
Under the regulations, a company that doesn’t want to disclose an ingredient that’s a trade secret has to explain why it should be protected. In those cases, the company would be required to provide contact information in case of emergencies. Information about the chemicals would be available to health professionals under a confidentiality agreement.
