Rule Summary

On January 15, 2021, EPA proposed changes to E15 fuel dispenser labeling requirements. E15 is a gasoline-ethanol blend that contains up to 15 percent ethanol and is currently available at over 1,800 retail stations.

EPA is also proposing to modify underground storage tank (UST) regulations to accommodate the safe storage of E15 and higher gasoline-ethanol blends at retail stations’ existing tank systems.
