| 2012-12230 | Approval and Promulgation of Air Quality Implementation Plans; Maryland; Baltimore Nonattainment Area Determinations of Attainment of the 1997 Annual Fine Particulate Standard | Rule | EPA is taking action to finalize two separate and independent determinations regarding the fine particulate matter (PM<INF>2.5</INF>) nonattainment area of Baltimore (hereafter referred to as the "Baltimore Area" or "Area"). First, EPA is determining that the Baltimore Area has attained the 1997 annual PM<INF>2.5</INF> National Ambient Air Quality Standard (NAAQS) under the Clean Air Act (CAA). This determination is based upon complete, quality-assured, and certified ambient air monitoring data for the 2008-2010 monitoring period showing that the Area has monitored attainment of the 1997 annual PM<INF>2.5</INF> NAAQS, and data available to date for 2011 in EPA's Air Quality System (AQS) database showing that the Area continues to attain. Under EPA's PM<INF>2.5</INF> implementation regulations, this final determination suspends obligation of the Area to submit an attainment demonstration and associated reasonably available control measures and reasonably available control technologies (RACM/RACT), a reasonable further progress (RFP) plan, contingency measures, and other planning State Implementation Plan (SIP) revisions related to the attainment of the standard for so long as the Area continues to attain the 1997 annual PM<INF>2.5</INF> NAAQS. EPA is also determining, based on complete quality-assured and certified monitoring data for the 2007- 2009 monitoring period, that the Area attained the 1997 annual PM<INF>2.5</INF> NAAQS by its applicable attainment date of April 5, 2010. In addition, EPA is withdrawing its July 31, 2009 (74 FR 38161) proposed determination of attainment for the Baltimore Area, because more recent monitoring data has become available. EPA is finalizing a determination of attainment for the Baltimore Area, in accordance with the requirements of the (CAA). | 2012-05-22 | 2012 | 5 | https://www.federalregister.gov/documents/2012/05/22/2012-12230/approval-and-promulgation-of-air-quality-implementation-plans-maryland-baltimore-nonattainment-area | https://www.govinfo.gov/content/pkg/FR-2012-05-22/pdf/2012-12230.pdf | Environmental Protection Agency | 145 | EPA is taking action to finalize two separate and independent determinations regarding the fine particulate matter (PM<INF>2.5</INF>) nonattainment area of Baltimore (hereafter referred to as the "Baltimore Area" or "Area").
