On March 25, 2026, the Trump administration issued an emergency EPA waiver, temporarily lifting the summer restrictions on E15 gasoline sales to address soaring fuel prices. Due to the Iran conflict leading to the closure of the Strait of Hormuz, approximately 20% of global oil supplies have been disrupted, causing gasoline prices to surge, with the national average price reaching $3.98 per gallon. EPA Administrator Lee Zeldin stated that the emergency EPA waiver aims to prevent fuel supply disruptions, while Agriculture Secretary Brooke Rolings said that the move would lower retail gasoline prices. Although the measure received bipartisan support, lawmakers like Senator Deb Fischer pointed out that it is not a long-term solution.
