The Iowa Republican is likely to support Wheeler's nomination for EPA administrator when the full Senate takes a vote, expected in the coming weeks, Pro Energy's Eric Wolff reports.

Grassley has pressured the agency to scale back economic hardship waivers that allowed dozens of small refineries to duck Renewable Fuel Standard mandates to blend biofuels with gasoline and diesel, or to buy credits instead.

After a recent conversation with Wheeler, Grassley said the nominee seemed to be "trying to accomplish what we want, but with no certainty" in terms of biofuel waivers.

Vote timing: Environment and Public Works Chairman John Barrasso (R-Wyo.) said Wheeler likely won't receive a Senate floor vote until the end of February, at the earliest, Pro Energy's Anthony Adragna reports.
