Introduction

The Environmental Protection Agency (EPA) has recently released preliminary calculations for the allocations of emission allowances under the Cross-State Air Pollution Rule (CSAPR) trading programs, specifically concerning the new unit set-asides (NUSAs) for the 2025 control periods. This announcement, while seemingly targeted at power plants and industrial facilities, carries potential ramifications for Community Development Block Grant Disaster Recovery (CDBG-DR) projects, particularly those involving infrastructure development, housing rehabilitation, and economic revitalization in affected areas.

CSAPR is a critical regulatory framework designed to reduce interstate air pollution transport and ensure downwind states attain and maintain National Ambient Air Quality Standards (NAAQS). The NUSAs are portions of allowances specifically designated for new or modified units, providing them with compliance flexibility under the CSAPR programs. Understanding the allocation of these allowances is crucial for assessing the environmental impact of CDBG-DR funded projects and ensuring their long-term sustainability.

Understanding the CSAPR and NUSA Framework

CSAPR addresses the problem of air pollution crossing state lines, focusing on pollutants like sulfur dioxide (SO2) and nitrogen oxides (NOx), which contribute to the formation of particulate matter and ozone. These pollutants can have significant health impacts, particularly on vulnerable populations, and can also damage ecosystems and infrastructure. CDBG-DR projects, often located in areas disproportionately affected by environmental hazards, must be designed and implemented in a manner that minimizes further environmental degradation.

The NUSAs are intended to accommodate new sources of emissions while maintaining overall emission reduction goals. The EPA’s preliminary calculations for the 2025 control periods provide critical data on the availability of these allowances. This data allows project developers and environmental regulators to evaluate the potential emissions associated with new or modified facilities supported by CDBG-DR funds. It’s important to note that these are preliminary calculations, and the EPA is accepting objections regarding the identification of eligible units and the allocation amounts before finalizing them.

Potential Implications for CDBG-DR Projects

CDBG-DR projects can be affected by CSAPR regulations in several ways:

• Infrastructure Development: New power plants, industrial facilities, or transportation infrastructure projects funded through CDBG-DR may be subject to CSAPR emission limitations. Understanding the availability of NUSA allowances is crucial for determining the feasibility and environmental compliance of these projects.
• Housing Rehabilitation: While less direct, housing rehabilitation projects that involve significant energy consumption (e.g., heating and cooling systems) can indirectly impact regional emissions. Promoting energy efficiency and renewable energy sources in these projects can help reduce overall demand for electricity generated by sources subject to CSAPR.
• Economic Revitalization: Attracting new businesses or expanding existing ones in disaster-affected areas is a key goal of CDBG-DR. If these businesses involve industrial processes with significant emissions, they will need to comply with CSAPR regulations. Access to NUSA allowances can be a factor in their location decisions.

Furthermore, CDBG-DR grantees must consider the environmental justice implications of their projects. Ensuring that projects do not disproportionately burden already vulnerable communities with additional air pollution is paramount. This requires careful consideration of cumulative impacts and the implementation of mitigation measures to minimize emissions.

Recommendations for CDBG-DR Grantees

To effectively address the potential impacts of CSAPR on CDBG-DR projects, grantees should:

• Review the EPA’s preliminary NUSA allocation data: Familiarize themselves with the allocation amounts for their region and assess the potential impact on proposed projects. The EPA’s website provides access to the relevant spreadsheets and documentation.
• Conduct thorough environmental assessments: Ensure that all CDBG-DR funded projects undergo comprehensive environmental reviews that consider potential air quality impacts and compliance with CSAPR regulations.
• Promote energy efficiency and renewable energy: Prioritize projects that reduce energy consumption and promote the use of renewable energy sources, thereby minimizing the demand for electricity generated by sources subject to CSAPR.
• Engage with stakeholders: Consult with local communities, environmental groups, and regulatory agencies to ensure that projects are designed and implemented in a manner that minimizes environmental impacts and promotes environmental justice.
• Consider submitting objections: If there are concerns regarding the identification of eligible units or the allocation amounts in the EPA’s preliminary calculations, consider submitting timely objections to the EPA for consideration.

Conclusion

The EPA’s announcement of preliminary CSAPR allowance allocations for the 2025 control periods is a timely reminder of the interconnectedness of environmental regulations and disaster recovery efforts. CDBG-DR grantees must proactively consider the implications of CSAPR for their projects and implement strategies to minimize environmental impacts and promote sustainable development. By doing so, they can ensure that disaster recovery efforts contribute to a cleaner, healthier, and more resilient future for affected communities.
