BACKGROUND.

Section 109(d)(1) of the CAA requires that the Agency periodically review and revise, as appropriate, the air quality criteria and the National Ambient Air Quality Standards (NAAQS) for the six “criteria” air pollutants, including ozone. From 2005 – 2008, a CASAC Ozone Review Panel conducted scientific reviews of EPA’s scientific assessments of the health and welfare effects of Ozone and other Photochemical Oxidants.

On September 16, 2009, the EPA Administrator announced a decision to reconsider the March 12, 2008 primary and secondary Ozone NAAQS to ensure they are scientifically sound and protective of public health and the environment. Pursuant to this decision, EPA has 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.

EPA’s Office of Air and Radiation has requested the 2005 – 2008 CASAC Ozone Review Panel to provide comments and advice on the January 2009 proposed Ozone standards.
