The Environmental Protection Agency (EPA) is proposing to determine that the Anderson and Freestone Counties and the Titus County nonattainment areas, in Texas, have 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. The primary sources of SO<INF>2</INF> emissions in these counties have permanently shut down and as a result air quality in these areas is now meeting the NAAQS for SO<INF>2</INF>. This proposed determination is supported by monitoring data from within or near to the nonattainment areas, emissions data and an evaluation of previous modeling.
The agency’s own summary, as published.
