Question

Quizplus · Accepted Answer

The federal government has the legal authority to enforce the national ambient air quality standards (NAAQS) if the state authorities fail to do so. The Clean Air Act empowers the EPA to establish and enforce the NAAQS, which all the states must comply with. States can choose to adopt standards that are more stringent than the NAAQS, but they cannot have weaker standards. The NAAQS are health-based standards that aim to safeguard the public from the harmful effects of air pollution. The standards cover air pollutants that are hazardous to human health and the environment, including particulate matter, ozone, nitrogen dioxide, sulfur dioxide, carbon monoxide, and lead. The NAAQS have primary and secondary standards. The primary standards provide human health protection while the secondary standards protect public welfare, including crops, forests, animals, and buildings, from adverse effects caused by air pollution.
