Two sources said the Trump administration could approve expanded biofuel
blending waivers for U.S. refineries as soon as Monday to blunt rising gasoline
prices. The EPA is expected to grant waivers to a batch of small refineries
covering more than 1.8 billion renewable fuel credits (RINs), filings include
Marathon Petroleum (MPC.N) and Chevron (CVX.N). That would be roughly double the
volume the agency initially planned to issue this year. Agricultural-state
lawmakers pushed the White House not to exceed earlier waiver levels; farmers
warn waivers would cut crop demand, and officials remain divided on whether the
expansion would materially lower pump prices. Under pressure from farm-state
allies, the EPA is also considering reopening the 2027 biofuel mandate and
adding about 500 million (or possibly more) RINs to offset harm to farmers.
