Last month, the Colorado Oil and Gas Conservation Commission (COGCC) approved a set of rules that codify many of the requirements in the emergency order the State issued in the wake of the April 2017 accident in Firestone, Colorado. In that accident, a buildup of natural gas leaked into a home through a pipeline that was thought to have been abandoned years earlier and exploded, killing two, and injuring others. Under the new rules, energy companies must now, among other things, ensure abandoned pipelines are severed from wells, conduct pressure tests on lines near homes, adhere to expanded testing requirements, work more closely with the “811-Call Before You Dig” system, and provide detailed geodatabase information about the pipelines to COGCC and general layout information to the public. Additionally, local governments will be able to access the geodata after signing a confidentiality agreement and must be notified of any “Grade One” gas leaks, that is, those that require immediate attention and pose a potential hazard. The new rules are hailed by government and industry leaders as a significant improvement to safety and as continued evidence that Colorado leads the nation in safe energy development.
