EPA’s Office of Research and Development has requested CASAC peer review of a draft document, "Integrated Science Assessment for Oxides of Nitrogen - Health Criteria (August 2007), intended to provide a synthesis and evaluation of science relevent for revising the primary (health-based) standards for the national ambient air quality standards for oxides of nitrogen. The CASAC plans to review two drafts of the Agency's 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 oxides of nitrogen. Primary standards set limits to protect public health, including the health of "sensitive" populations such as asthmatics, children, and the elderly.
