Title: Air Quality Designations and Classifications for the 2008 Ozone National Ambient Air Quality Standards
Abstract: This action will would establish the air quality designations for all areas of the United States under the revised 2008 ozone NAAQS. Designations of attainment, nonattainment, or unclassifiable are based upon air quality monitoring data and other relevant information pertaining to the air quality in the affected area, including whether an area contributes to a violation of the standard in a nearby area. The schedule and process for designations is contained in CAA section 107. Under the schedule, States and tribes are to submit their designation recommendations no later than 1 year from promulgation of the revised NAAQS. EPA is required to notify States and tribes of any modifications that EPA intends to make to their recommendations no later than 120 days prior to promulgation of the designations. EPA must make the designations no later than 2 years from the March 12, 2008, promulgation of the revised NAAQS. However, EPA may extend that date by up to 1 year if EPA has insufficient information. On January 6, 2010, EPA issued a proposal to reconsider the 2008 ozone NAAQS and instead set more protective NAAQS. If EPA promulgates new NAAQS as a result of the reconsideration, the requirement to designate areas for the replaced 2008 NAAQS would no longer apply. Because of the uncertainty created by the reconsideration of the 2008 ozone NAAQS, on January 6, 2010, EPA announced it extended the designations deadline by 1 year, until March 12, 2011.
