State oil and gas regulators are investigating reports that environmental consultants falsified results of tests on soil, groundwater and contamination at about 350 locations in Weld County between 2021 and this summer. The information was submitted on behalf of some of Colorado’s largest oil and gas producers and was intended to determine whether work to clean up spills or close oil and gas sites met the state’s cleanup standards. The Colorado Energy and Carbon Management Commission, which regulates the oil and gas industry, said Tuesday that based on its preliminary investigation, the agency is confident that there’s no new risk to public health beyond the original conditions that prompted the work. “ECMC has also put in place additional safeguards to prevent falsified data from being submitted in the future, including requiring additional documentation and examining metadata,” the agency said in a statement. The ECMC began looking into the lab results during the summer when operators notified the state of the potential falsification of information.
