On February 14, Senator Roger Wicker (R-MS) introduced, S. 344, a bill to prohibit the EPA from approving the introduction of gasoline that contains greater than 10 per cent ethanol. The bill has three co-sponsors. The key to the Wicker bill is that it would nullify any EPA granted waiver to mitigate mis-fueling.

On February 27, James Sensenbrenner (R-WI) introduced H.R. 875 to provide for a comprehensive assessment of the scientific and technical research on the implications of the use of mid-level ethanol blends. The Sensenbrenner bill takes a different approach to the problems caused by mid-levels of ethanol blends. However, both bills would nullify EPA granted waivers. H.R. 857 also prohibits the EPA from issuing new waivers until the results of the additional research are complete. In addition, H.R 875 specifically includes testing of the effect of ethanol on marine engines and fuel systems and the potential of mis-fueling at various points in the distribution and supply chains. The bill provides $900,000 to pay for the testing to be taken out of already appropriated research funds.

MRAA supports both S. 344 and H.R. 875. It is expected the House Environment Subcommittee will mark up the Sensenbrenner bill in early summer with floor action in the House possible in the fall.
