      Typically, during the summer, the U.S. government restricts fuel sales to a specific blend that evaporates less to reduce pollution. However, the ongoing conflict in Iran has disrupted fuel prices throughout the year. In response, the Environmental Protection Agency and Department of Energy have issued an emergency waiver allowing the sale of E10 gas with a higher evaporation rating starting September 1, two weeks earlier than its usual introduction to consumer supply.

      For much of 2026, the EPA has permitted the sale of gasoline containing up to 15% ethanol, even during the typically banned hottest months. This decision is based on the idea that reducing fuel can help lower pump prices. However, higher ethanol content and increased Reid Vapor Pressure (RVP) values—which indicate evaporation or volatility—can worsen ground-level ozone during high temperatures, leading to cardiovascular and respiratory health risks. This is why such blends are typically reserved for fall and winter.

      As previously discussed, increasing ethanol in gasoline can also lead to issues for older vehicles not designed for it. Even vehicles meant for such blends will likely experience a minor decrease in fuel efficiency, as ethanol contains less energy than pure gasoline.

      In its announcement, the EPA mentioned it has waived “state level controls in Texas, Arizona, and California that extend beyond September 15, 2026, for the maximum allowed period of 20 days,” and will continue to renew these waivers as deemed necessary. The department also criticized “blue-state politicians in New York and California” for not adopting these standards, which increases prices for their residents. Notably, both states contain some of the largest cities in the nation, where millions of residents are more severely affected by diminished air quality compared to those in more rural areas.
