This bill tells the Environmental Protection Agency (EPA) to quickly finish its 2021 rule on E15 fuel pump labels and on whether underground fuel tanks can safely store fuel with up to 15% ethanol. The EPA must finalize the rule within 90 days and use the “first co-proposal” for E15 pump labeling from that 2021 plan. It also sets clear rules so more existing fuel tanks can be used with up to 15% ethanol without extra paperwork or full system upgrades. For the future, any new or replaced parts must be able to handle up to 100% ethanol after the rule takes effect.

Key points

• Who is affected: EPA; gas stations and other owners/operators of underground storage tanks that hold motor fuel for on-road vehicles.
• What changes:
  • EPA must finalize its E15 labeling rule using the first co-proposal from 2021.
  • Existing underground tank systems are treated as compliant for up to 15% ethanol, even if owners can’t find old installation or compatibility papers.
  • Steel and fiberglass tanks made after July 2005, and all fiberglass reinforced plastic piping, are considered compatible with up to 15% ethanol.
  • If owners can show certain parts (like gaskets or seals) work with up to 15% ethanol, they don’t have to replace other equipment to make the whole system compliant.
  • Any tanks or parts installed or replaced after the rule takes effect must be compatible with up to 100% ethanol, including items like pipe sealants.
• When: The EPA must finish the rule within 90 days of the law taking effect; the future-proofing requirement applies to equipment installed or replaced after the rule’s effective date .
