Summary

Nullifies an EPA rule that approved California’s heavy‑duty vehicle emission standards and several related measures (advanced clean trucks, zero‑emission airport shuttles, warranty/maintenance provisions, and powertrain certification). It declares that the specified EPA rule has no force or effect, preventing the agency’s regulatory action from taking effect if the resolution becomes law. The measure directly removes the legal effect of a single EPA regulatory action; it does not create new regulatory requirements or funding, but it would change the federal regulatory landscape for vehicle and engine emissions, state waiver decisions, manufacturers, fleets, and other stakeholders that planned for or relied on that EPA decision.

Key Points

• Repeals an EPA final rule concerning California heavy‑duty vehicle and engine standards and related zero‑emission programs.
• Declares that the named EPA rule “shall have no force or effect,” nullifying the agency action if the resolution becomes law.
• Covers multiple program elements: advanced clean trucks, zero‑emission airport shuttles, zero‑emission powertrain certification, and warranty/maintenance provisions.
• Does not create replacement standards, funding, or new federal regulatory requirements—only removes the legal effect of the existing EPA rule.
• Likely to affect automakers, engine and component suppliers, fleet operators, airports, and states that adopt California standards by removing the federal rule basis they were anticipating.
• May increase regulatory and market uncertainty for manufacturers and buyers planning for zero‑emission heavy‑duty vehicles and associated infrastructure.
• Could prompt legal challenges or follow‑on rulemaking by EPA or legislative/regulatory responses by states and industry.
• Implementation depends on enactment; nullification halts the specific EPA action but does not itself resolve related policy or emissions goals.
