A major Trump administration action to expand the availability of higher blends of biofuels suffered a significant legal setback Friday that could lead to a fresh moratorium on summertime sales of 15% ethanol blends.

Sen. Chuck Grassley, R-Iowa, says the Environmental Protection Agency is no longer considering a controversial provision that would have made exported ethanol and biodiesel eligible for the credits used to measure compliance with the federal blending mandate.

The House Energy and Commerce environment subcommittee on Friday examined the potential impacts a transition to higher octane fuels could have on refiners, biofuel producers, automakers and consumers.

President Donald Trump delivered welcome news to supporters of the Renewable Fuel Standard on Thursday, confirming that the administration is seriously considering a waiver for year-round E15 sales.

WASHINGTON, June 14, 2017 – A hearing of the Senate Environment and Public Works Committee left backers of a bill that would expand sale of higher ethanol blends encouraged, but the legislation has an uncertain future.

WASHINGTON, Mar. 16, 2017 - In order to extend the Reid vapor pressure (RVP) waiver to ethanol blends above 10 percent, senators Deb Fischer, R-Neb., Joe Donnelly, D-Ind., and Chuck Grassley, R-Iowa, have introduced the Consumer and Fuel Retailer Choice Act.
