The EPA is delaying its official decision on approving E15 for 2001-2006 model year vehicles until early 2011. The Agency is also being sued by the American Petroleum Institute and nine food and farm groups; again because the EPA is running afoul of the Clean Air Act. In response to that lawsuit, EPA Deputy Press Secretary Betsaida Alcantara told Green Car Advisor a while back:
[The] decision was based on strict adherence to the Clean Air Act and was grounded firmly in science. The agency relied on rigorous testing that the Energy Department did on 19 car models, in consultation with automakers and fuel suppliers. This decision is sound, and the agency is confident that it will withstand legal challenge.
