EPA’s National Center for Environmental Assessment has requested consultation in developing a plan for the development of the Integrated Science Assessment for Nitrogen Oxides – Health Criteria, which will serve as the scientific basis for review of the primary (health-based) standards for the national ambient air quality standards for nitrogen oxides.
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.
|EPA released the Integrated Science Assessment for Oxides of Nitrogen – Health Criteria (Final Report)
|EPA held a workshop entitled "Kickoff Workshop to Inform EPA's Review of the Primary NO2 NAAQS'" co-organized by EPA/ORD/NCEA and the EPA/OAQPS Staff to help with the development of future products on this subject matter. The workshop was held February 29 - March 1, 2012, in Research Triangle Park, North Carolina. [Federal Register Notice Feb 10, 2012]
|EPA released the draft development plan for the next Integrated Science Assessment (ISA) for the health effects of nitrogen oxides (NOx). [Federal Register Notice May 3, 2013]
|EPA's Science Advisory Board's CASAC held a June 2013 consultation by the Oxides of Nitrogen Review Panel on the Draft Plan for the Development of the Integrated Science Assessment for Oxides of Nitrogen. [Federal Register Notice May 10, 2013]
