National Ambient Air Quality Standards

National Ambient Air Quality Standards (NAAQS) are regulations established by the U.S. Environmental Protection Agency (EPA) to protect public health and the environment from harmful air pollutants. These standards set acceptable levels of specific pollutants, such as ozone, particulate matter, and carbon monoxide, in the air. Local governments monitor air quality and implement measures to ensure that pollution levels stay within these established limits. By doing so, NAAQS help reduce health risks, promote cleaner air, and support overall well-being in communities.
