Read More Lawmakers discuss two new air quality bills State lawmakers are considering two air quality bills. The bills aim to bring oil and gas companies in Colorado in line with the U.S. Clean Air Act. State officials, according to Colorado Newsline, say the overall objective of Senate Bills 24-165 and 24-166 is to bring Colorado into compliance with the Environmental Protection Agency's ozone standards by 2027. SB 24-165 requires deep reductions in ozone emissions. 24-166 is aimed at companies that repeatedly violate air quality laws. Both bills, 165 in particular, are facing stiff opposition from Colorado's oil and gas industry. Industry spokespeople say that if 165 becomes law, it would require pauses in seasonal drilling, resulting in decreased production. Opponents of the bills also say that the measures target Suncor, which has a history of air quality violations. Suncor, a Canadian company with a refinery in Commerce City, is not specifically named in the text of either bill.
