BACKGROUND.

On September 16, 2009, the EPA Administrator announced her decision to reconsider the March 12, 2008 primary and secondary Ozone National Ambient Air Quality Standards (NAAQS) to ensure they are scientifically sound and protective of public health and the environment. Pursuant to this decision, EPA proposed on January 6, 2009 to set different primary and secondary standards than those set in 2008 to provide requisite protection of public health and welfare, respectively (75 FR 2938 - 3052).

In response to a request from EPA's Office of Air and Radiation, the CASAC Ozone Review Panel for the Reconsideration of the 2008 NAAQS will provide advice on the strengths and limitations of the scientific evidence and technical information for EPA’s reconsideration of the 2008 Ozone NAAQS. This advice will supplement advice on this topic provided in a letter dated February 29, 2010 (EPA-CASAC 10-007).
