DENVER (AP) – Colorado regulators have approved new rules requiring energy companies to publicly disclose chemicals used in hydraulic fracturing but allowing them to protect trade secrets and to provide 48 hours notice before pumping chemicals underground.
The Colorado Oil and Gas Conservation Commission unanimously approved the rules Tuesday. The process also known as fracking involves blasting water, sand and chemicals into rock formations to free oil and natural gas that’s credited for playing a role in opening up many gas reserves.
Under the regulations, a company can claim a trade secret but has to explain why it should be protected.
In those cases, the company would be required to publicly release information about the chemical family and concentration. Detailed would be available in case of emergencies.
