H.R. 4214: Clean Air and Building Infrastructure Improvement Act

The Clean Air and Building Infrastructure Improvement Act is a legislative proposal focusing on the management of air quality regulations and permitting processes. The bill introduces amendments to the Clean Air Act that would affect how national ambient air quality standards are implemented in the United States.

Key Provisions

The main aspects of the bill include:

• Concurrent Regulation Publication: The bill mandates that when the Environmental Protection Agency (EPA) establishes or revises national ambient air quality standards (NAAQS), it must also publish regulations and guidance to help states and permit applicants understand how to implement these standards at the same time.
• Impact on Preconstruction Permits: For new construction projects or modifications, the new standards will not apply until the EPA publishes the necessary implementing regulations. If the EPA does not publish these regulations concurrently with the new standard, the standard will not affect the review of related preconstruction permit applications until this guidance is available.
• Preconstruction Permit Application Rules: Specific guidelines are outlined for how certain preconstruction permit applications related to the 2024 Primary Annual Particulate Matter_2.5 Standard will be managed. If a determination about an application is made before the area's designation according to the standard, it may not need to comply with the new standard.
• Obligations for Applicants: Despite these changes, applicants for preconstruction permits are still required to utilize the best available control technology and meet the lowest achievable emission rate standards as outlined in the existing law. Furthermore, state or local authorities retain the ability to impose stricter emissions requirements if they choose.

Definitions

The bill also provides definitions for key terms such as:

• Best Available Control Technology: The technology that provides the highest degree of emission reduction that has been demonstrated to be available.
• Lowest Achievable Emission Rate: The lowest rate of emissions that can be achieved through the application of technology that has been demonstrated in practice.
• Preconstruction Permit: A permit required for the construction or modification of a stationary source as stipulated under the Clean Air Act.
• National Ambient Air Quality Standard: National air quality standards established by the EPA to protect public health and the environment.

Implementation Timeline

The bill emphasizes the timely issuance of regulations and guidance to support the preconstruction permitting process, ensuring a clearer pathway for stakeholders when national standards are revised or established.
