Denver—The gas line explosion that killed two men in Firestone eight months ago wasn’t the only one to occur in Colorado this year. According to state records, two other people have died in oil and gas explosions since the deadly blast in April. In fact the record shows about a dozen industry explosions have been reported to the Colorado Oil and Gas Conservation Commission since then. The state has yet to take enforcement action in the Firestone deaths, citing a lack of industry rules dealing with fatal accidents. The COGCC has suggested changes to existing regulations but nothing dealing with fatalities. Officials say they do not have the authority to impose penalties for deadly explosions.
