This bill proposes to amend the Clean Air Act to expand the scope of the renewable fuel program. Specifically, it seeks to include fuel for ocean-going vessels as an additional category for which renewable fuel credits may be generated, aligning it with existing provisions for home heating oil and jet fuel. The amendment would take effect in the first calendar year following the bill's enactment. Furthermore, it mandates that the Administrator of the Environmental Protection Agency (EPA) promulgate necessary regulations to implement these changes within 365 days. The EPA Administrator is also required to submit a report to Congress on the implementation and regulations within 365 days after the final regulations are issued.
