What is the aim of CAA Subchapter I, Part C §7470-79?

The aim of the Clean Air Act (CAA) Subchapter I, Part C, specifically sections 7470-79, is to prevent significant deterioration of air quality. This legislation establishes a framework aimed at protecting air quality in areas that meet the National Ambient Air Quality Standards (NAAQS), ensuring that air pollution does not worsen in these already clean areas.

By setting these guidelines, the regulation seeks to maintain air quality levels while allowing for economic growth and development. It emphasizes the importance of balancing industrial activities and urban development with the need to safeguard public health and the environment from air pollution.

The other choices, while related to environmental protection in some capacity, do not directly connect to the specific goals and provisions established in these sections of the CAA. For example, vehicle emission testing and alternative fuels are important initiatives but fall under different parts of the regulations. Carbon trading systems also have their framework, but are not covered by this specific part which focuses more on air quality maintenance rather than economic mechanisms for pollution reduction.
