On August 2, 2018, the U.S. Environmental Protection Agency (EPA) and the National Highway Traffic Safety Administration (NHTSA) issued a notice of proposed rulemaking (NPRM), the Safer Affordable Fuel-Efficient (SAFE) Vehicles Rule for Model Years 2021–2026 Passenger Cars and Light Trucks (SAFE Vehicles Rule), relating to the national automobile fuel economy and greenhouse gas (GHG) emissions standards set by EPA for cars and light-duty trucks.
The proposed SAFE Vehicles Rule is the expected next step in the Trump Administration’s efforts to reevaluate fuel economy and emissions standards set by the Obama Administration. In 2012, the Obama Administration set GHG and fuel economy standards for passenger cars and light-duty trucks for model years 2017 to 2025, but EPA and NHTSA committed in that rulemaking to “a comprehensive midterm evaluation and agency decision-making process for the MYs 2022–2025 standards.” This “midterm evaluation” was to be completed by April 1, 2018.
On December 6, 2016, the Obama EPA published a “proposed determination,” finding that the standards set in the October 2012 rule should remain in place, and on January 12, 2017, the agency issued a final determination to that effect. In March 2017, the Trump EPA announced its intention to reconsider that final determination. And in April 2018, the agency formally withdrew the Obama Administration’s January 2017 final determination and announced that it would initiate a notice and comment rulemaking to evaluate the appropriate standards for MYs 2022–2025.
The SAFE Vehicles Rule is the first step in the rulemaking process to evaluate the appropriate future GHG emissions and fuel economy standards for light-duty vehicles. The proposed rulemaking includes several important developments of interest for the automotive industry:
The SAFE Vehicles Rule will be published in the Federal Register in the coming weeks, and will be open for public comment for a period of 60 days after publication. In addition, EPA and NHTSA will hold three public hearings on the rule in Washington, DC, Detroit, MI, and Los Angeles, CA. The dates for these hearings will be announced in a forthcoming notice in the Federal Register.
If the agencies’ preferred proposals are adopted and the rule becomes final, it is virtually certain that the revised standards and the withdrawal of California’s waiver authority will be challenged in court by California and other states, and by the environmental community.
 The official version of the SAFE Vehicles Rule will be published in the Federal Register in the coming weeks. Until it is published, the proposed rule is available at https://www.epa.gov/sites/production/files/2018-08/documents/safe-my-2021-2026-cafe-ld-ghg-nhtsa-epa-nprm-2018-08-02.pdf.
