{"abstract":"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, whether the standards for model years 2022-2025 are appropriate.\\1\\ In accord with this schedule, as noted in the March 22, 2017, document and this document, EPA intends to make a Final Determination regarding the appropriateness of the model year 2022-2025 standards no later than April 1, 2018. In this document, EPA is also requesting comment on the separate question of whether the light-duty vehicle greenhouse gas standards established for model year 2021 remain appropriate, regardless of the agency's decision on the MTE. ---------------------------------------------------------------------------","action":"Request for comment.","agencies":[{"raw_name":"DEPARTMENT OF TRANSPORTATION","name":"Transportation Department","id":492,"url":"https://www.federalregister.gov/agencies/transportation-department","json_url":"https://www.federalregister.gov/api/v1/agencies/492","parent_id":null,"slug":"transportation-department"},{"raw_name":"National Highway Traffic Safety Administration","name":"National Highway Traffic Safety Administration","id":345,"url":"https://www.federalregister.gov/agencies/national-highway-traffic-safety-administration","json_url":"https://www.federalregister.gov/api/v1/agencies/345","parent_id":492,"slug":"national-highway-traffic-safety-administration"},{"raw_name":"ENVIRONMENTAL PROTECTION AGENCY","name":"Environmental Protection Agency","id":145,"url":"https://www.federalregister.gov/agencies/environmental-protection-agency","json_url":"https://www.federalregister.gov/api/v1/agencies/145","parent_id":null,"slug":"environmental-protection-agency"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2017/08/21/2017-17419.html","cfr_references":[{"chapter":null,"citation_url":null,"part":86,"title":40},{"chapter":null,"citation_url":null,"part":523,"title":49},{"chapter":null,"citation_url":null,"part":531,"title":49},{"chapter":null,"citation_url":null,"part":533,"title":49},{"chapter":null,"citation_url":null,"part":536,"title":49},{"chapter":null,"citation_url":null,"part":537,"title":49}],"citation":"82 FR 39551","comment_url":null,"comments_close_on":"2017-10-05","correction_of":null,"corrections":[],"dates":"Comments must be received on or before October 5, 2017.
