In City of Longmont v. Colorado Oil & Gas Association, the Colorado Supreme Court reviewed a home-rule municipality's authority to ban hydraulic fracturing ("fracking") within its city limits. Longmont voters passed a 2012 charter amendment prohibiting fracking and the disposal of associated waste. The Colorado Oil & Gas Association, supported by the Colorado Oil and Gas Conservation Commission, challenged the ban, arguing it conflicted with state law.
The district court invalidated the ban, holding that it was preempted by the Colorado Oil and Gas Conservation Act. Longmont and several environmental groups appealed, asserting that the home-rule provision of the Colorado Constitution gave the city authority to regulate local land use.
Supreme Court Ruling
The Colorado Supreme Court affirmed the district court’s ruling, finding that the fracking ban operationally conflicted with state law. Key points included:
-
Operational Conflict Doctrine: The court held that Longmont’s ban materially impeded the implementation of the state’s interest in the efficient development of oil and gas resources. Colorado law authorizes the Oil and Gas Conservation Commission to regulate drilling, spacing, and environmental protection statewide.
-
Local vs. State Interests: While recognizing Longmont's interest in protecting public health and land use, the court found that fracking involves mixed state and local concerns. The need for uniformity in oil and gas regulation outweighed Longmont's local interests.
-
Preemption Principles: The court emphasized that local ordinances cannot override state law in matters of mixed concern. Longmont's ban effectively prohibited an activity explicitly authorized by state regulations.
-
Environmental Considerations: Although environmental groups highlighted potential health risks, the court concluded that the state's regulatory framework adequately addressed these concerns, leaving no room for local bans.
Implications
This decision underscores the limitations of local government authority in regulating industries subject to comprehensive state oversight. It reaffirms the state’s role in balancing resource development with environmental protection.
