Legislation sponsored by Rep. James Sensenbrenner (R-WI) could delay getting 15% ethanol blended fuel in the marketplace by requiring even more testing by the Environmental Protection Agency.

The bill out of the Science, Space, and Technology Committee’s Energy and Environment Subcommittee has the backing of numerous anti-ethanol organizations, including the including petroleum, livestock, environmental and food industry groups. It would require EPA to contract with the National Academy of Sciences to study the effects of E15 on vehicles and engines. “The EPA’s decision to rush introduction of E15 into the marketplace raised a red flag, and stakeholders are speaking out before it’s too late,” Sensenbrenner said.

Growth Energy CEO Tom Buis notes that E15 has been tested more than any other fuel in history. “This is a waste of time and a waste of taxpayer dollars,” Buis said. “No fuel blend has undergone the level of scrutiny E15 has – and passed the tests like E15 did. They’ve been looking at E15 for more than three years.”

The Green Jobs Waiver for E15 was accompanied with more independently-gathered data, science and research in its support than any of the other 11 Clean Air Act waivers previously approved by the U.S. EPA. The agency approved the use of E15 in vehicles newer than 2001 more than a year ago, but it has yet to reach the consumer marketplace.
