This bill cancels an EPA waiver granted in January 2025 that let California enforce its "Omnibus" Low NOx Regulation, a stricter emissions standard for heavy-duty trucks and engines. Using the Congressional Review Act, Congress overturned the EPA's decision, so the waiver and California's rule no longer have legal effect.
Truck and engine manufacturers, trucking companies, and residents of California and other states that follow California's vehicle emissions standards are mainly affected.
Without the waiver, California cannot enforce its stricter NOx limits, so manufacturers face no requirement to meet them there, potentially resulting in higher air pollution levels than expected under the cleaner-engine rule.
