DENVER (AP)-The Colorado Oil and Gas Conservation Commission is reviewing whether companies have injected fluids containing diesel fuel into the ground to help extract oil and gas in Colorado.
On Monday, congressional Democrats, including Colorado Rep. Diana DeGette, said they found that from 2005 to 2009, companies have injected more than 1.3 million gallons of hydraulic fracturing fluids containing diesel fuel underground in Colorado without first getting a certain permit. They said it's unclear how drinking water was affected.
Commission Director David Neslin said Tuesday that the commission is looking into whether diesel fuel has been used, and if so, when, in what amounts and whether its use was consistent with Colorado regulations.
Neslin says a fundamental part of the commission's regulatory mission is protecting groundwater.
