Draft Plan for Development of the Integrated Science Assessment for Nitrgen Oxides Health Criteria
EPA is releasing the Draft Plan for Development of the Integrated Science Assessment for Nitrogen Oxides - Health Criteria as announced in a May 3, 2013 Federal Register Notice. Comments must be received on or before May 31, 2013.
On June 11,2013, EPA will host a workshop to review these materials. [Federal Register Notice May 10, 2013]
EPA has announced a draft development plan for the next Integrated Science Assessment (ISA) for the health effects of nitrogen oxides (NOX) which will serve as the scientific basis for review of the primary (health-based) National Ambient Air Quality Standard for nitrogen dioxide. The ISA is intended to provide a comprehensive assessment of the current scientific literature pertaining to known and anticipated effects on public health associated with the NOX in the ambient air. The Preamble that has been included in previous ISAs is provided here as a resource for review of the ISA development plan, since it describes the general processes for ISA development.
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 nitrogen oxides. Primary standards set limits to protect public health, including the health of "sensitive" populations such as asthmatics, children, and the elderly.
