6. Description of content:  Proposed rule - EPA is proposing to correct an error in EPA's 
regulations for test procedures used in the Corporate Average Fuel Economy (CAFE) 
program  finalized in a 2012 rulemaking. EPA established the procedures under the general 
provisions of Energy Policy and Conservation Act (EPCA) which authorize EPA to establish 
test and calculation procedures for CAFE. The correction clarifies the method for how  flex-
fuel vehicles are accounted for in manufacturer fuel economy calculations in model years 
2020 and later. This correction allows the program to be implemented as originally 
intended in the 2012 rule. This proposed action is not expected to result in a ny significant 
changes in regulatory burdens or costs. In the "Rules and Regulations" section of this 
Federal Register, we are taking direct final action without a prior proposed rule. If we 
receive no adverse comment, we will not take further action on th is proposed rule.
