Delta Construction Co. v. EPA
United States Court of Appeals for the District of Columbia Circuit
783 F.3d 1291 (2015)
The Environmental Protection Agency (EPA) (defendant) promulgated regulations of greenhouse-gas emissions and fuel-efficiency standards (the regulations) pursuant to the Clean Air Act. Fuel-efficiency standards were also regulated by the National Highway Traffic Safety Administration independently of the EPA. The EPA’s regulations were challenged by two sets of plaintiffs. A group of businesses, associations, and individuals (collectively, the California petitioners) (plaintiffs) argued that the EPA failed to comply with statutory requirements when it promulgated the regulations and claimed that the regulations increased the price of vehicles. Separately, Plant Oil Powered Diesel (POP Diesel) (plaintiff), a company that altered diesel engines to run on vegetable oil, challenged the regulations as arbitrary and capricious and claimed that the regulations would make POP Diesel’s business economically infeasible by encouraging the use of gasoline through their fuel-efficiency improvement standards and their failure to provide incentives for the use of vegetable-oil fuel. The EPA moved to dismiss both cases, arguing that the plaintiffs lacked standing.
