Background on the Issue

The US government, under President Trump’s administration, has issued an emergency exemption allowing the sale of a gasoline blend with higher ethanol content for the Northern Hemisphere summer season across the country. This move aims to supplement fuel supply during peak driving season and reduce costs.

Beneficiaries of the Decision

This decision is expected to benefit biofuel producers and corn farmers, as it will expand the market for their products. Both industries have been advocating for nationwide sale of E15, a blend containing 15% ethanol, throughout the year.

Government’s Stance on Restrictions

Currently, the government restricts the sale of gasoline E15 during summer months due to environmental concerns about smog. The biofuels industry claims these concerns are unfounded.

Exemption Details

The emergency exemption, effective May 1st, was issued by the Environmental Protection Agency (EPA) and is expected to be extended until it’s no longer deemed necessary. In recent years, the EPA has granted similar exemptions for summer seasons.

Industry Reaction

Geoff Cooper, President of the Renewable Fuels Association, praised the swift action by President Trump and EPA Administrator Lee Zeldin to address potential fuel shortages and help control gasoline prices this summer amid global energy market turbulence.

EPA’s Decision on State Regulations

The EPA stated it was waiving provisions that would have otherwise required gasoline E10 sold in Illinois, Iowa, Minnesota, Missouri, Nebraska, South Dakota, and Wisconsin to meet a stricter standard than conventional gasoline in other parts of the country.
