Integrated Plan for Lead NAAQS Review - Integrated Science Assessment


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. An early step in EPA’s process for reviewing the NAAQS is to develop a plan for reviewing the science associated with the primary and secondary NAAQS. EPA has requested that CASAC provide consultative advice on EPA’s planning document for the Integrated Science Assessment for Lead, being developed as part of the review of the NAAQS for lead.
