The Environmental Protection Agency (EPA) is proposing to redesignate certain unclassifiable areas 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 believes that it now has sufficient information to determine that certain unclassifiable areas in Missouri, Nebraska, Ohio, and Texas are attaining the 2010 1-hour SO<INF>2</INF> primary NAAQS, and, therefore, is proposing to redesignate these areas to attainment/unclassifiable for the 2010 1-hour SO<INF>2</INF> primary NAAQS.
The agency’s own summary, as published.
