Alliance of Automobile Manufacturers v. EPA

–

On February 21, 2017, the Alliance of Automobile Manufacturers (AAM) submitted a letter to EPA Administrator G. Scott Pruitt requesting that EPA withdraw the Final Determination on the Appropriateness of the Model Year 2022-2025 Light-Duty Vehicle Greenhouse Gas Emissions Standards under the Midterm Evaluation. EPA issued the final determination a week before President Obama left office. AAM asked that EPA resume the Midterm Evaluation of the standards to rectify procedural and substantive defects, including failure to provide opportunity for meaningful notice and comment and failure to harmonize the greenhouse gas standards with the National Highway Traffic Safety Administration fuel economy standards. AAM also asserted that the final determination was “riddled with indefensible assumptions, inadequate analysis, and a failure to engage with contrary evidence” and that EPA had not received certain “highly relevant” studies and data because they were still pending.
