In a decision released this morning, the DC Circuit rejected a challenge to the introduction of E15, a gasoline blended with 15 percent ethanol, under an EPA waiver grant. Currently, the national gasoline supply consists largely of E10, a 10 percent ethanol/gasoline blend. With fuel manufacturers confronting mandatory annual increases of renewable fuels under the Renewable Fuel Standard (RFS), Growth Energy, a trade association representing the ethanol industry, had sought an EPA waiver for a new 15 percent ethanol/gasoline blend. The EPA provided partial waivers (1 and 2), under the Clean Air Act for the E15 blend, restricting the fuel’s use to light duty motor vehicles and engines from model-year 2001 and newer. Three sets of industry groups representing engine manufacturers, food producers and petroleum suppliers then sued, challenging the EPA’s waivers.
In a 2-1 decision, the court declined to make a decision on the merits, finding that the petitioners lacked standing to bring the action. In a strongly worded dissent, Circuit Judge Brett Kavanaugh disagreed. Kavanaugh then addressed the merits of the case, finding they were “not close.” He concluded that in granting the E15 partial waiver the “EPA ran roughshod over the relevant statutory limits.”
Where We Go From Here
The decision preserves flexibility for implementing the RFS renewable fuels mandates – for now. However, the lack of a decision on the merits means the EPA waiver process remains vulnerable to judicial challenge. In the meantime, the debate over corn-based ethanol fuel mandates may be shifting to Congress, as predictions for historically low corn crop yields continue to accumulate.
