Citation(s): Alaska Dept. of Environmental Conservation v. EPA, 540 U.S. 461 (2004)
Short summary
Alaska’s Department of Environmental Conservation determined what pollution-restricting technology should be implemented for a mine expansion, per requirements of the Clean Air Act. The federal Environmental Protection Agency intervened, disagreeing with Alaska’s determination of which technology to utilize. The Supreme Court affirmed the Ninth Circuit Court of Appeals’ ruling that the Environmental Protection Agency properly overruled Alaska’s initial determination.

Weight of decision
This decision is binding on all United States federal and state courts.
Key facts
Under the Clean Air Act (CAA), state agencies must identify the best strategy to prevent air quality from deteriorating in regions that comply with national air quality standards. In part, they must ensure that polluting industries utilise the “best available control technology” to restrict pollution whenever they construct new facilities. Teck Cominco Alaska, a mining firm, applied for a permit to develop a new generator at one of its mines in 1998. The permit was issued by the Alaska Department of Environmental Conservation (ADEC), and it required Cominco to use “Low NOx” technology in all its generators, not just the new one. However, the Environmental Protection Agency (EPA) intervened, claiming that a more advanced technique was available and should be utilized.
Previous instances
The EPA’s decision was challenged by ADEC in the Ninth Circuit Court of Appeals, arguing that the EPA lacked the authority to interfere with the state agency’s decision under the CAA. The Ninth Circuit ruled in favour of the EPA.
Summary of holding
On appeal, the Supreme Court was asked to settle whether if the EPA, under the CAA, has the authority to overrule a state agency’s decision that a company is using the “best available controlling technology” to prevent pollution.
§ 165(a)(4) of the CAA stipulates that no large air pollutant-emitting plant can be built unless it is fitted with the best available control technology. Furthermore, when EPA finds that a state is not complying with a CAA requirement governing the construction of a pollutant source, it has the authority to issue an order prohibiting construction, impose an administrative penalty, or file a civil action for injunctive relief under § 113(a)(5) of the CAA. § 167 of the CAA authorizes EPA to take any necessary action, including issuing an order or pursuing injunctive relief, to prevent the construction of a significant pollutant-emitting plant that does not comply with the CAA’s pollutant criteria.
