Abstract
The Environmental Protection Agency (EPA) is taking final action to determine that the Jefferson County nonattainment area, in Missouri, has attained the 2010 1-hour primary Sulfur Dioxide (SO<INF>2</INF>) National Ambient Air Quality Standard (NAAQS) per the EPA's Clean Data Policy. This determination of attainment is based upon complete, quality assured, and certified ambient air monitoring data from the 2014-2016 monitoring period, associated dispersion modeling, and supplemental emissions inventory information, which demonstrate that the Jefferson County area attained the 2010 1-hour primary SO<INF>2</INF> NAAQS.
