Colorado got generally high marks in an outside review of its rules governing oil and gas operations and hydraulic fracturing, but the review said the state could go farther to protect groundwater supplies. The review was by STRONGER (short for â¿¿State Review of Oil & Natural Gas Environmental Regulationsâ¿). The nonprofit organization, based in Oklahoma City, was formed in 1999 and has received funding from the U.S. Environmental Protection Agency, the U.S. Department of Energy and the American Petroleum Institute, an industry trade group. In this state, oil and gas operations are overseen by the Colorado Oil & Gas Conservation Commission, a division of the Department of Natural Resources. â¿¿Overall weâ¿¿re pleased with the recommendations; it was a positive review,â¿ said David Neslin, COGCCâ¿¿s director, in an interview. COGCC has already met with state public health and water resources officials to work on recommendations made in the report. The agency also will hold a stakeholder meeting to review the report, Neslin said. The review panel met in Denver on June 23. The STRONGER report ( download here) found several strengths in Coloradoâ¿¿s existing rules: â¿¢ The stateâ¿¿s rules were updated recently, in 2008, and include language governing hydraulic fracturing, also called â¿¿fracking,â¿ operations. Fracking cracks underground rock formations with water, sand and chemicals to release oil and natural gas. The industry says the practice is safe if done correctly, but concerns have been raised about potential environmental harm. â¿¢ Coloradoâ¿¿s rules require that oil and gas companies disclose the contents of frack fluid to agency officials and health care professionals who sign a confidentiality agreement when an incident has occurred. The report said the rules allow the agency and health care officials to address possible chemical contamination while protecting proprietary information.
