House Passes Year-Round Ethanol Bill as Senate Path Remains Unclear
House approves year-round E15 ethanol sales as gas prices hit $4.55 per gallon, but Senate passage remains uncertain.
RALEIGH, NORTH CAROLINA — The U.S. House of Representatives has passed legislation allowing year-round sales of E15 gasoline blends containing 15% ethanol, but the measure faces an uncertain path in the Senate where supporters need 60 votes to advance.
The legislation would lift current federal regulations that restrict E15 sales from June 1 to September 15 due to air quality concerns. Proponents argue year-round availability would provide consumers with a less expensive fuel alternative, boost energy supplies, and benefit agricultural interests.
“I don’t know if it can get 60, to be honest with you,” Senate Environment and Public Works Committee Chair Shelley Moore Capito, a Republican from West Virginia, said in an interview.
Gas Price Surge Drives Support
The push for expanded E15 availability has gained momentum as gasoline prices have soared due to ongoing turmoil from the war in Iran. AAA reported that the national average for regular gasoline reached $4.55 per gallon on May 22, 2026, up from $3.20 a year earlier.
The steep price increase has directed some lawmakers’ attention toward alternative fuels like ethanol as potential relief for consumers facing higher costs at the pump.
Senate Leadership Weighs Options
Senate Majority Leader John Thune offered cautious optimism about the bill’s prospects when speaking with reporters. “We’re looking at ways to move it,” Thune said. “We have people here who represent states that also have refineries, and that’s a factor in this conversation.”
The debate highlights competing interests within Congress, with lawmakers from corn-growing states supporting expanded ethanol use while representatives from oil-producing and refining states express reservations about the legislation.
Environmental advocates have also raised concerns about year-round E15 sales, creating what observers describe as an unusual alliance with oil industry interests opposing the measure.
Congressional Timeline
The Senate is expected to take up the issue when Congress returns from its Memorial Day recess in June. The White House has signaled its support for the legislation, but the measure’s success largely depends on whether supporters can secure the 60 Senate votes needed to overcome potential procedural hurdles.
Current federal regulations classify E15 as contributing to air quality problems during summer months, when higher temperatures and increased sunlight can worsen smog formation. The restriction has limited the fuel blend’s availability during peak driving season.
Supporters argue that lifting the seasonal ban would provide immediate relief to consumers facing record-high gas prices while supporting domestic agricultural production and reducing dependence on foreign oil imports.
