EPA’s Office of Air and Radiation has requested CASAC advice on a draft EPA planning document entitled "Review of the National Ambient Air Quality Standards for Lead: Risk and Exposure Assessment Planning Document.."

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 lead. 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 decreased visibility, damage to animals, crops, vegetation, and buildings.
