BACKGROUND.

EPA’s Office of Air and Radiation and Office of Research and Development requested the Clean Air Scientific Advisory Committee to provide advice and review of the environmental assessments and the policy assessment (previously called the “Staff Paper”) supporting the review and possible revision of the primary (health-based) and secondary (welfare-based) standards for the national ambient air quality standards for ozone. Under the Clean Air Act, EPA is required to carry out a periodic review and revision, as appropriate, of the air quality criteria and the primary and secondary standards for six criteria air pollutants, which include ozone. Primary standards set limits to protect public health, including the health of "sensitive" populations such as asthmatics, children, and the elderly. Secondary standards set limits to protect public welfare, including protection against visibility impairment, damage to animals, crops, vegetation, and buildings.
