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. EPA is currently reviewing the Lead National Ambient Air Quality Standards (NAAQS). 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. EPA has requested that CASAC provide consultative advice on Volume 3 of the Lead IRP. This volume discusses key considerations related to planning decisions on quantitative exposure and risk analyses that may be warranted for the review.
