The EPA wants to say yes to South Carolina's plan to update how they trade pollution credits for certain gases that can travel to other states. These updates help keep the air cleaner, and the plan follows all the rules without adding new ones.
Summary AI
The Environmental Protection Agency (EPA) is proposing to approve a State Implementation Plan (SIP) revision from South Carolina's Department of Health and Environmental Control. This revision updates the state's participation in the Cross-State Air Pollution Rule (CSAPR) emissions trading programs for nitrogen oxides (NOX) and sulfur dioxide (SO2). These programs are designed to help reduce air pollution that affects other states. The EPA believes the proposed changes align with federal requirements and do not impose new obligations beyond what state law already specifies.
Abstract
The Environmental Protection Agency (EPA) is proposing to approve a State Implementation Plan (SIP) revision submitted through the South Carolina Department of Health and Environmental Control (SC DHEC) on September 26, 2023, regarding updates to the State's Cross- State Air Pollution Rule (CSAPR) emissions trading programs. The SIP revision incorporates by reference (IBRs) certain amendments EPA has made to the regulations for the Federal CSAPR trading programs for annual emissions of nitrogen oxides (NO<INF>X</INF>) and sulfur dioxide (SO<INF>2</INF>) for large electric generating units (EGUs). EPA created these Federal trading programs in 2011 as market-based mechanisms for South Carolina and certain other States to address their obligations to downwind States under the Clean Air Act (CAA or Act)'s good neighbor provision with respect to the national ambient air quality standards (NAAQS) for fine particulate matter (PM<INF>2.5</INF>). EPA is proposing to approve South Carolina's September 26, 2023, SIP revision because it is consistent with EPA's good neighbor CSAPR trading programs and the CAA.

The Environmental Protection Agency (EPA) is taking steps to approve updates to South Carolina’s participation in a federal air pollution program known as the Cross-State Air Pollution Rule (CSAPR). This action is meant to align South Carolina's regulations with recent federal changes and ensure the state continues to address air quality standards in neighboring states effectively.
Overview
This proposed rule by the EPA aims to revise South Carolina’s participation in the CSAPR emissions trading programs. These programs regulate the emissions of nitrogen oxides (NOX) and sulfur dioxide (SO2) from large electrical generating units. The goal is to manage air pollutants that travel across state lines and contribute to poor air quality in neighboring areas. The document outlines adjustments to align state rules with federal updates made in 2021 and 2022.
Issues and Concerns
One of the notable challenges within the document is its complexity and technical language, which might be dense for readers not familiar with legal or environmental jargon. While it addresses the incorporation of federal rule changes, it might not provide sufficient detail on the intended environmental or public health benefits. Additionally, the document does not thoroughly explore the financial implications or the potential costs to implement these changes at the state level.
Moreover, while it mentions environmental justice, the document does not delve deeply into how these regulatory changes will specifically affect communities historically impacted by air pollution. There is also no detailed explanation of the expected impact on local air quality, or how this might address public concerns.
Impacts on the Public and Stakeholders
For the general public, these updates might not lead to immediate or noticeable changes. However, the long-term benefits could include improved air quality and a reduction in health issues linked to air pollution, such as asthma or other respiratory conditions. By aligning with federal standards, South Carolina aims to maintain clean air practices that contribute to healthier living conditions.
Specific stakeholders, such as operators of large power plants, might face consequences regarding compliance with these more recent federal adjustments. The document lacks a detailed discussion on how these facilities, which were aligned with the 2016 regulations, will transition to the updated rules. This could involve administrative adjustments and potential costs associated with adapting to the updated regulations.
Conclusion
In summary, while the EPA’s proposal to approve South Carolina’s revised air pollution regulations is a technically sound steps towards maintaining regional air quality, it could benefit from clearer communication about financial, environmental, and societal impacts. Addressing these areas more comprehensively might aid in public understanding and ensure stakeholders are adequately prepared for compliance. Without this, there remains a risk of confusion and insufficient engagement with the stakeholders directly affected by these changes.
Issues
• The document does not mention any specific financial or budgetary implications of the proposed rule, but additional details on implementation costs and impacts on state resources may be lacking.
• The technical language and legal references throughout the document could be dense and difficult for laypersons to understand, particularly the detailed explanations of amendments and regulatory citations.
• There is no detailed analysis of potential environmental justice concerns, although it notes that such considerations are not required for this action. Clarifying whether affected communities were consulted might enhance transparency.
• The document could benefit from additional clarity on the specific changes in emissions trading protocols and their expected impact on South Carolina's air quality in plain language.
• The document's repeated references to historical changes and updates to regulatory language could potentially lead to confusion without a clear, summarized timeline of changes.
• Potential implications for entities that previously adhered to the 2016 regulations are not thoroughly discussed in terms of compliance burdens or adjustments required under the updated rules.
