Air Quality Standards

Air Quality Standards

Air quality standards are established to protect even the most sensitive individuals in our communities. These standards indicate the maximum amount of a pollutant that can be present in outdoor air without harm to the public's health. Both the California Air Resources Board (ARB) and the U.S. Environmental Protection Agency (USEPA) are authorized to set ambient air quality standards.
