Consumer and Fuel Retailer Choice Act of 2023

This bill amends the Clean Air Act to modify how the EPA handles waivers for ethanol in gasoline, specifically regarding "Reid Vapor Pressure" (a measure of fuel evaporation). It simplifies the process for fuel retailers to introduce certain ethanol blends into commerce by allowing them to meet vapor pressure standards through existing vehicle certification or approved waivers, rather than requiring new EPA approval for each blend. The key change removes barriers for retailers selling ethanol blends that comply with existing vehicle standards or approved waivers, directly affecting fuel manufacturers and retailers who must meet EPA fuel regulations. This is a technical regulatory adjustment focused on streamlining compliance, not creating new consumer benefits or programs.
