This bill proposes to amend the Clean Air Act to broaden the definition of renewable fuel, specifically by including fuel for ocean-going vessels . This inclusion would allow for the generation of credits under the existing renewable fuel program, thereby extending renewable energy incentives to the maritime sector. The amendment modifies Section 211(o)(1)(A) of the Clean Air Act, adding fuel for ocean-going vessels to the list of fuels for which renewable credits can be generated. This change is designed to take effect starting the second calendar year following the bill's enactment. To ensure proper implementation, the bill mandates that the Administrator of the Environmental Protection Agency (EPA) issue all necessary regulations within one year of enactment. Additionally, the EPA Administrator is required to submit a comprehensive report to Congress within one year of promulgating these final regulations, detailing the amendment's implementation and the associated rules.
