Abstract

The Environmental Protection Agency (EPA) is redesignating the Lancaster County, Nebraska and Milam County, Texas unclassifiable areas initially designated during the EPA's Round 2 air quality designations for the 2010 1-Hour Sulfur Dioxide (SO<INF>2</INF>) Primary National Ambient Air Quality Standard (NAAQS). Specifically, the EPA now has sufficient information to determine that these unclassifiable areas in Nebraska and Texas are attaining the 2010 1-hour SO<INF>2</INF> primary NAAQS. Therefore, the EPA is redesignating these areas to attainment/ unclassifiable for the 2010 1-hour SO<INF>2</INF> primary NAAQS. The EPA is also approving these states' requests to redesignate the areas.
