Determination of Attainment of the 2008 Ozone National Ambient Air Quality Standards; Eastern San Luis Obispo, California

摘要

The Environmental Protection Agency (EPA) is proposing to determine that the San Luis Obispo County (Eastern San Luis Obispo) ozone nonattainment area (NAA) has attained the 2008 ozone National Ambient Air Quality Standards (NAAQS or "standards") by the applicable attainment date of July 20, 2016. This determination is based on complete, quality-assured and certified data for the 3-year period preceding that attainment date. If the determination is finalized, the Eastern San Luis Obispo NAA will not be reclassified to a higher ozone classification.
