Determination of Attainment by the Attainment Date for the 2010 1-Hour Primary Sulfur Dioxide National Ambient Air Quality Standard; Texas; Freestone-Anderson and Titus Counties

Pursuant to the Federal Clean Air Act (CAA or the Act), the Environmental Protection Agency (EPA) is finalizing our determination that the sulfur dioxide (SO<INF>2</INF>) nonattainment area (NAA) in Freestone and Anderson Counties and the SO<INF>2</INF> NAA in Titus County have each attained the 2010 1-hour primary SO<INF>2</INF> national ambient air quality standard (NAAQS) by the applicable attainment date of January 12, 2022. This determination is based on primary source shutdowns, available ambient air quality monitoring data from the 2019-2021 monitoring period, relevant modeling analysis, and additional emissions inventory information. This final action will address the EPA's obligation under CAA section 179(c) to determine whether the Freestone-Anderson and Titus SO<INF>2</INF> NAAs attained the 2010 1-hour primary SO<INF>2</INF> NAAQS by the statutory attainment date of January 12, 2022, for each area.
