FR 2020-28020

The Environmental Protection Agency (EPA) has finalized and approved a rule aimed at reducing the emissions of oxides of nitrogen (NOX) from on-road heavy-duty vehicles in the South Coast Air Quality Management District in California. This rule will take effect on February 16, 2021, and forms part of the California State Implementation Plan (SIP). The plan is named the South Coast Incentive Measure and relies on commitments made by the California Air Resources Board (CARB) to achieve specific reductions in NOX emissions.

General Summary

The document lays out a comprehensive plan for lowering air pollution by focusing on emissions from heavy-duty vehicles. The goal is to improve air quality, in line with the requirements set out by the Clean Air Act (CAA). The revision includes certain binding commitments on CARB, such as achieving a specified reduction in emissions, ensuring compliance with guidelines, and submitting annual reports about the progress. The rule also allows enforcement actions by both citizens and the EPA if the stipulated goals are not met.

Significant Issues and Concerns

One notable issue with the document itself is its complexity. It’s replete with legal and regulatory jargon, which could make it difficult for the general public to fully understand. While the intentions behind the rule are clear, the specifics of how these aims will be achieved are mired in technical details and guidelines. For instance, the reliance on the "2017 Carl Moyer Guidelines" could pose an accessibility issue, as it may not be easily obtainable or interpretable by non-experts.

Moreover, the rule has detailed responses to public comments, particularly those by Earthjustice, which highlight concerns about enforceability and the specific means of achieving the goals. However, these responses themselves are dense and could benefit from more straightforward clarity to reassure stakeholders about how these regulatory commitments will be enforced.

Broad Public Impact

For the general public, especially those living in areas affected by air pollution from heavy-duty vehicles, this rule stands to bring about improvements in air quality. By setting enforceable targets for emission reductions, the rule aims to create a cleaner environment, which could have health benefits for people exposed to high levels of air pollutants.

In terms of public participation, the rule outlines the ability for citizens to engage through enforcement actions if CARB fails to meet its commitments. This inclusion of a legal pathway for the public to ensure compliance underscores the participatory role citizens can have in environmental regulation.

Impact on Specific Stakeholders

Positive Impacts:

• Environmental Organizations: Groups focused on air quality improvement and environmental health could see this as a win, as it sets enforceable targets and maintains accountability for emissions reductions.

• Residents in Affected Areas: Communities in areas with heavy air pollution may experience improved health outcomes and quality of life as air quality improves over time.

Negative Impacts:

• Transport and Industrial Stakeholders: Entities tied to on-road heavy-duty vehicles might bear the brunt of implementing new technologies or practices to meet these requirements. Compliance could entail significant costs or operational changes.

• Regulatory and Legal Professionals: The complexity of the document implies a significant workload for those involved in ensuring compliance, interpreting the rule’s requirements, and addressing any enforcement or legal challenges.

In conclusion, while the rule aims to make strides toward reducing pollution and improving public health, its success will largely depend on clear communication and effective enforcement of the commitments outlined. The technical and legal intricacy of the document demands careful interpretation both by regulated entities and those in positions of oversight.
