H.J. Res. 87 (Public Law 119-15) is a congressional disapproval resolution that prevents an Environmental Protection Agency (EPA) rule from taking effect. The rule, submitted by the EPA on April 6, 2023 (88 Fed. Reg. 20688), related to California’s authority to enforce stricter vehicle emission standards, including for heavy-duty trucks, zero-emission airport shuttles, and advanced clean truck requirements. By disapproving this rule, Congress blocks California from implementing these specific pollution controls under its existing waiver authority. This directly affects California’s ability to regulate motor vehicle emissions independently, as the rule would have allowed the state to enforce its own standards beyond federal requirements.

H.J.Res. 88 disapproves an Environmental Protection Agency (EPA) rule that would have allowed California to enforce its "Advanced Clean Cars II" vehicle emission standards. This rule, submitted by the EPA on January 6, 2025, sought to grant California a waiver to override federal preemption for its stricter vehicle pollution controls. The resolution, passed by Congress and signed into law on June 12, 2025, formally nullifies the EPA rule, preventing California from implementing its Advanced Clean Cars II program under this specific waiver. The bill directly affects California's ability to set its own vehicle emission standards for passenger cars and light trucks.

HJRES 89 is a congressional disapproval resolution that blocks an Environmental Protection Agency (EPA) rule concerning California's vehicle and engine pollution standards. The resolution specifically targets the EPA's "Omnibus Low NOX Regulation" and waiver of preemption, which would have allowed California to enforce stricter emissions rules. By disapproving this rule under Chapter 8 of Title 5 U.S. Code, Congress has nullified the EPA's action, meaning the regulation will have no legal effect. This directly affects the EPA's authority to approve California's state-level pollution control standards for motor vehicles.
