(Reuters) – U.S. senators reintroduced a bipartisan bill on Tuesday that would allow nationwide sales of gasoline with a higher blend of ethanol year-round, as a second heavy-weight oil trade group appeared ready to back the idea.

Republican Senator Deb Fischer from Nebraska and Democratic Senator Amy Klobuchar from Minnesota – both major corn-producing states – argue that the expanded sales of E15, or fuel containing 15% ethanol, would decrease gasoline prices and reduce U.S. dependence on foreign oil. Year-round sales of E15 have been long sought by the biofuel industry and corn farmers, who would benefit from the increased market.

AFPM said that while the bill needed work, a legislative approach was less disruptive than creating patchwork requirements for new fuel blends.
