The Colorado Oil and Gas Commission (Commission) has challenged a Longmont City Council ordinance, approved on July 17, 2012, that includes new oil and gas restrictions and a ban on hydraulic fracturing in residential areas. Colorado Oil & Gas Conservation Comm’n v. City of Longmont, No. N/A (Colo. Dist. Ct. filed 7/30/12). The complaint seeks a declaration that the ordinance, which is more stringent than regulations administered by the Commission, is preempted. It attacks the city’s position in the ordinance that it has authority to promulgate “land use” restrictions within its boundaries, including restrictions on industrial activity within its borders. The Commission also argues that a statute delegates the development of oil and gas resources to the Commission and the ordinance interferes with the Commission’s authority.
