This determination is based on quality-assured and certified monitoring data for the 2007- 2009 monitoring period. Based on this data, EPA previously determined on May 23, 2011, that the area attained the 1997 standards, and EPA suspended certain planning requirements for the area based on that determination. EPA is now finding that the St. Louis area attained the 1997 annual PM<INF>2.5</INF> NAAQS by its applicable attainment date. EPA is finalizing this action because it is consistent with the CAA and its implementing regulations. | 2012-06-27 | 2012 | 6 | https://www.federalregister.gov/documents/2012/06/27/2012-15573/approval-and-promulgation-of-implementation-plans-and-designations-of-areas-for-air-quality-planning | https://www.govinfo.gov/content/pkg/FR-2012-06-27/pdf/2012-15573.pdf | Environmental Protection Agency | 145 | EPA is determining, pursuant to the Clean Air Act (CAA), that the bi-state St. Louis, Missouri-Illinois, fine particulate (PM<INF>2.5</INF>) nonattainment area (hereafter referred to as "the St. Louis area" or "the area") has attained the 1997 annual... |
