The Ethanol for America Act of 2025 requires the Environmental Protection Agency (EPA) to finalize a proposed rule concerning E15 fuel dispenser labeling and underground storage tank compatibility within 90 days of enactment. This legislation aims to standardize regulations for ethanol-blended fuels. Specifically, the Administrator must finalize the first co-proposal for E15 labeling. For underground storage tank compatibility with fuel blends up to 15 percent ethanol, the bill mandates that existing underground storage tank systems are deemed compliant, even without specific documentation. It also considers steel and fiberglass underground storage tanks manufactured after July 2005 and all fiberglass reinforced plastic piping as compatible with E15. Furthermore, owners can demonstrate compatibility for individual components like gaskets or seals without replacing the entire system. To ensure future flexibility, any newly installed or replaced components of underground storage tank systems must be compatible with fuel blends containing up to 100 percent ethanol, regardless of the fuel currently stored.
