1. Abstract
The US Congress is currently debating a bill very important to transportation and air quality. Lawmakers have been presented with an opportunity to protect public health and reject recent efforts to weaken the Clean Air Act. The $318-billion Senate transportation bill would increase federal funding for transportation programs intended to improve air quality. To reject the bill would mean that people living in urban areas with higher vehicle emission levels would experience much poorer air quality. Furthermore, the Environmental Protection Agency’s (EPA) latest pollution data indicates that many of these areas are already out of compliance with the new federal “eight hour ozone standard”. The EPA concluded that car and truck emissions are the largest source of smog forming pollutants in these areas and are the major cause of non-compliance.
2. Background
Air quality is a matter of growing concern. The increasing individual awareness of the seriousness of air pollution has been reflected publicly in a series of legislative and administrative actions designed to guide public agencies in the formation of tools for achieving satisfactory standards of air quality.
The air quality maintenance task undertaken by the EPA in 1975 was designed to ensure that the National Ambient Air Quality Standards are maintained. The program was designed to consider the impact of future of growth and development on air quality and to develop control strategies to ensure that air quality will not deteriorate from the standards.
