The Safer Affordable Fuel-Efficient 'SAFE' Vehicles Rule

Sept. 19, 2019: NHTSA and EPA establish One National Program for fuel economy regulation

"The Safer Affordable Fuel-Efficient (SAFE) Vehicles Rule Part One: One National Program" takes the first step toward finalizing the agencies' August 2018 proposal by announcing EPA's decision to withdraw California's waiver of preemption under Section 209 of the Clean Air Act, and finalizing NHTSA's regulatory text relating to preemption under 49 U.S.C. 32191. The agencies anticipate issuing a final rule on standards in the near future.

Sept. 21, 2018:  U.S. DOT and EPA extend comment period for SAFE Vehicles proposal

To ensure that Clean Air Act requirements are met and to provide maximum lead time for automakers, U.S. DOT and EPA are extending the comment period for the SAFE Vehicles proposal to October 26, 2018.  DOT is also extending the comment period for its Draft Environmental Impact Statement to October 26, 2018.  Comments may still be submitted to the proposal via the link below.

Aug. 2, 2018: U.S. DOT and EPA propose SAFE Vehicles Rule

The Safer Affordable Fuel-Efficient (SAFE) Vehicles Rule would amend existing Corporate Average Fuel Economy (CAFE) and tailpipe carbon dioxide emissions standards for passenger cars and light trucks and establish new standards covering model years 2021 through 2026. The proposal would retain the model year 2020 standards for both programs through model year 2026. If adopted, the proposed rule’s preferred alternative would save more than $500 billion in societal costs and reduce highway fatalities by 12,700 lives (over the lifetimes of vehicles through MY 2029).

NHTSA and EPA are seeking comment on this proposal, the analysis on which it is based, and a wide variety of alternative options for 60 days following official publication in the Federal Register. The agencies will hold three public hearings in Fresno, Calif.; in Dearborn, Mich.; and in Pittsburgh, Penn.; for members of the public who wish to comment in person. Dates and locations of the hearings are available in the link below.
