National Highway Traffic Safety Administration Finalizes Next Set of Corporate Average Fuel Economy Standards

On Friday, June 7, 2024, the U.S. Department of Transportation National Highway Traffic Safety Administration (NHTSA) finalized its corporate average fuel economy (CAFE) standards for model years (MY) 2027 through 2032 passenger cars and light-duty trucks. The standards will push automakers to increase fleetwide fuel economy by approximately 2% each year, which is less aggressive than the 4% increase for light-duty trucks considered in NHTSA’s July 2023 proposed rule. Taken together, NHTSA predicts that the fleetwide average fuel economy across the industry will reach 50.4 miles per gallon by 2031, while increased upfront vehicle costs would offset lifetime fuel savings over time.

NHTSA Adopts Rule Requiring Automatic Emergency Braking on Light Vehicles

On May 9, 2024, the National Highway Traffic Safety Administration (NHTSA) published a final rule adopting a Federal Motor Vehicle Safety Standard (FMVSS) that requires automatic emergency braking (AEB) systems in U.S. light vehicles and trucks by September 2029. The rule is required under the Bipartisan Infrastructure Law of 2021 (BIL), in which Congress directed NHTSA to establish FMVSS requirements for AEB systems as well as three other Level 2 advanced driver assistance systems (ADAS): lane departure warnings, lane-keeping assist, and forward collision warnings (FCW).

U.S. EPA Proposes Revisions to Project Emissions Accounting Under New Source Review

The U.S. Environmental Protection Agency (EPA) is proposing revisions to the New Source Review (NSR) permitting program that would make it more difficult to net out of NSR requirements by changing how to calculate the net emissions resulting from a facility modification. EPA also proposes to define the term “project” more narrowly to prevent sources from aggregating changes to net out of major NSR requirements. The proposal would revise reforms adopted only four years earlier during the Trump administration that had provided additional flexibility to sources making changes to their operations.

On Wednesday, May 1, the White House Council on Environmental Quality (CEQ) published Phase 2 of its National Environmental Policy Act (NEPA) rulemaking, concluding the Biden-Harris administration’s multiyear effort to “simplify and modernize” the federal environmental review process. CEQ’s Phase 2 rulemaking is broader and more comprehensive than Phase 1 — which primarily restored three narrow elements of the NEPA regulations to their pre-2020 form — and incorporates amendments as directed by Congress under the Fiscal Responsibility Act (FRA) and BUILDER Act of 2023, including page and time limits for environmental assessments (EA) and environmental impact statements (EIS).  (more…)
