Colorado would require energy companies to disclose substantially more information about the chemical ingredients of hydraulic fracturing fluid used to crack underground rock formations to access oil and natural gas, according to draft rules released Tuesday.
Hydraulic fracturing (fracking) has been used in Colorado’s oil and gas industry for decades, but concerns have risen about the ingredients of the fluid and whether they may cause environmental damage or harm public health.
Gov. John Hickenlooper in August said he wanted new rules by year-end, requiring companies to publicly disclose the contents of the fracking fluid, following the lead of other states, including Wyoming and Texas.
