National Ambient Air Quality Standards (NAAQS)

National Ambient Air Quality Standards (NAAQS) are regulatory limits established by the Environmental Protection Agency (EPA) to protect public health and the environment from harmful air pollutants. These standards set acceptable levels for six common pollutants, including ground-level ozone and particulate matter. The NAAQS guide air quality management efforts at the federal, state, and local levels, ensuring that the air we breathe meets safety criteria. Regular assessments are made to adapt the standards based on scientific research and health data, thereby promoting cleaner air and safeguarding communities' health.
