Collaboration between policy-makers and the scientific community can have a continued positive impact on air quality in the U.S. This collaboration has been the primary cause for the improvements observed in air quality over the past few decades.
U.S. Environmental Protection Agency (EPA) programs, such as the New Source Performance Standards (NSPS), New Source Review, and Maximum Achievable Control Technology standards, have all had a significant impact on improving air quality by lowering the ambient concentrations of NOX, VOC, CO, SOX, and PM.
