What is mandated by CAA §7403 regarding the prevention and control of air pollution?

The correct answer pertains to the creation of a research and development program, which is indeed mandated by the Clean Air Act (CAA) §7403. This section focuses on the need for comprehensive research and development initiatives aimed at identifying effective methods and technologies for preventing and controlling air pollution. Through this approach, the CAA encourages innovation and exploration of new techniques that can lead to more effective air quality management, ultimately guiding emissions standards and regulatory measures.

The emphasis on research and development aligns with the broader goals of the CAA to improve air quality through scientific understanding and technological advancement, thereby addressing pollution sources more effectively. The act recognizes that improving air quality is not solely about imposing regulations but also requires investment in knowledge and technological solutions that can help achieve sustainable outcomes.
