On April 11, the House Science, Space, and Technology Committee approved a bill that would prevent the Environmental Protection Agency (EPA) from issuing 15 percent ethanol (E15) waivers and would repeal any current waivers until the National Academy of Sciences performs an 18 month study on the effects of E15 on vehicles and fuel economy. The legislation specifies that the Academy must present the findings to the House Science, Space, and Technology Committee and the Senate Environment and Public Works Committee before the EPA can start approving the fuel again. These waivers approve E15 for vehicles made in model year 2001 and beyond. The bill, H.R. 875, was introduced by Rep. Jim Sensenbrenner (R-WI) and was approved by a vote of 18-17.
