SUPPLEMENTARY INFORMATION: In the 

Final Rules Section of this Federal 

Register, EPA is approving the State’s 

implementation plan revision as a direct 

final rule without prior proposal 

because the Agency views this as a 

noncontroversial submittal and 

anticipates no adverse comments. A 

detailed rationale for the approval is set 

forth in the direct final rule. If no 

adverse comments are received in 

response to this rule, no further activity 

is contemplated. If EPA receives adverse 

comments, the direct final rule will be 

withdrawn and all public comments 

received will be addressed in a 

subsequent final rule based on this 

proposed rule. EPA will not institute a 

second comment period on this 

document. Any parties interested in 

commenting on this document should 

do so at this time. 

Dated: August 4, 2017.

Request for Comment on 

Reconsideration of the Final 

Determination of the Mid-Term 

Evaluation of Greenhouse Gas 

Emissions Standards for Model Year 

2022–2025 Light-Duty Vehicles; 

Request for Comment on Model Year 

2021 Greenhouse Gas Emissions 

Standards 

AGENCY: National Highway Traffic 

Safety Administration (NHTSA), 

Department of Transportation (DOT), 

Environmental Protection Agency 

(EPA). 

ACTION: Request for comment. 

SUMMARY: In a March 22, 2017, Federal 

Register document, the Environmental 

Protection Agency (EPA) announced its 

intention to reconsider the Final 

Determination of the Mid-term 

Evaluation of greenhouse gas emissions 

standards for model year 2022–2025 

light-duty vehicles and to coordinate its 

reconsideration with the parallel 

rulemaking process to be undertaken by 

the Department of Transportation’s 

National Highway Traffic Safety 

Administration (NHTSA) regarding 

Corporate Average Fuel Economy 

(CAFE) standards for cars and light 

trucks for the same model years. In this 

document, EPA is announcing that it is 

reconsidering whether the light-duty 

vehicle greenhouse gas standards 

previously established for model years 

2022–2025 are appropriate under 

section 202(a) of the Clean Air Act and 

invites stakeholders to submit any 

comments, data, and information they 

believe are relevant to the 

Administrator’s reconsideration of the 

January 2017 Mid-term Evaluation Final 

Determination and in particular, 

highlight any new information. As part 

of a 2012 joint final rulemaking by the 

EPA and NHTSA, the Mid-term 

Evaluation process was codified in EPA 

regulation for greenhouse gas emission 

standards for model years 2017–2025 

light-duty vehicles, which requires EPA 

to determine no later than April 1, 2018,
