A bill barring the introduction of E15 into the marketplace has been introduced by Representative Jim Sensenbrenner. If passed, the bill would amend the Clean Air Act to prohibit the EPA from granting a waiver for any fuel or additive that would reduce fuel efficiency or contribute to engine damage.

Sensenbrenner expressed concern that E15 could damage engines and reduce fuel efficiency. The bill claims that the U.S. DOE’s testing was limited in scope and did not consider evidence showing possible negative effects of the fuel on certain engines.    “Consumers need to be able to trust fuel at the pump,” he said.

The Renewable Fuels Association dismissed the congressman’s claims about the safety of E15, claiming that Sensenbrenner’s suggestion that E15 is unsafe is wrong. In a statement, the group said that the EPA has put the fuel through significant testing, and has crafted a label and misfueling plan to ensure that consumers are properly and legally using increased levels of ethanol.

In October, the senator introduced another bill that would require independent scientific analysis to be conducted on the implications of E15 in vehicles, marine, and small engines.
