Bottom line

This joint resolution aims to block California's stricter heavy-duty vehicle emission standards by nullifying the EPA's approval of the state's waiver, thereby preventing a patchwork of state-specific regulations and potentially reducing compliance burdens on the trucking industry.

What it actually does

This joint resolution seeks to disapprove and nullify a rule submitted by the Environmental Protection Agency (EPA) on April 6, 2023. The EPA rule in question granted California a waiver of preemption under the Clean Air Act, allowing the state to implement its own stricter emission standards for heavy-duty vehicles, including the Advanced Clean Trucks program and related warranty and certification provisions. If enacted, S.J. Res. 46 would prevent these California standards from taking effect by rendering the EPA's approval of the waiver null and void.

Proponents argue

Supporters argue that the EPA rule grants California undue authority to set de facto national standards, creating a burdensome and inconsistent regulatory environment for the interstate trucking industry and vehicle manufacturers. They contend that disapproving the rule would ensure regulatory consistency across states, reduce compliance costs for businesses, and prevent potential increases in consumer prices or supply chain disruptions. Furthermore, proponents may argue it reasserts congressional authority over agency rulemaking.

Opponents contend

Opponents contend that disapproving this rule undermines California's long-standing authority under the Clean Air Act to address its unique and severe air quality challenges, as well as the ability of other states to adopt these more protective standards. They argue that nullifying the rule would hinder efforts to reduce harmful air pollution, worsen public health outcomes, and slow the transition to cleaner, zero-emission transportation technologies necessary to combat climate change.

The bill is exceptionally short and clear, requiring minimal time to read and understand its core intent.

Disapproval of EPA Rule on California Heavy-Duty Vehicle Emission Standards

prominently featuredstraightforward

This provision explicitly states that Congress disapproves of the Environmental Protection Agency's rule, published on April 6, 2023, concerning California's heavy-duty vehicle and engine emission control standards. These standards include the Advanced Clean Trucks program, heavy-duty vehicle and engine emission warranty and maintenance provisions, zero-emission airport shuttle requirements, and zero-emission powertrain certification. As a direct consequence of this disapproval, the EPA rule would have no legal force or effect, meaning California's waiver to implement these stricter standards would be nullified.

Supporters argue

Supporters argue that this provision is necessary to prevent a fragmented regulatory landscape that burdens interstate commerce and increases costs for the trucking industry. They believe a single national standard is more efficient and that California's rule represents an overreach that could negatively impact the economy.

Critics contend

Opponents contend that this provision strips California of its critical authority under the Clean Air Act to protect its residents from harmful pollution and innovate in clean transportation. They argue it would set back efforts to improve air quality and address climate change, especially in communities disproportionately affected by vehicle emissions.

Tradeoffs

This provision highlights the tension between promoting national regulatory uniformity for industry and allowing states to set more stringent environmental standards to address local concerns. It also balances the economic costs of compliance for businesses against the public health and environmental benefits of reduced emissions.
