Nationwide Consumer and Fuel Retailer Choice Act of 2023

This bill amends the Clean Air Act to adjust fuel standards and support small refineries. It changes how the EPA grants waivers for fuel additives (allowing fuels similar to certified vehicles or meeting specific waiver conditions) and modifies Reid Vapor Pressure limits from "10 percent" to "10 to 15 percent" for certain fuels. Small refineries that retired credits for 2016-2018 compliance years and had pending or denied petitions by December 2022 can now have those credits returned or applied to future compliance. The bill directly affects fuel retailers, ethanol producers, and small refineries by altering compliance rules and credit eligibility under the renewable fuel program.
