| E9-18393 | Approval and Promulgation of Air Quality Implementation Plans; West Virginia; Determination of Clean Data for the 1997 Fine Particulate Matter Standard | Proposed Rule | EPA is proposing to determine that the West Virginia portions of three nonattainment areas for the 1997 fine particulate (PM<INF>2.5</INF>) National Ambient Air Quality Standard (NAAQS) have clean data for the 1997 PM<INF>2.5</INF> NAAQS. These are Berkeley County, part of the Hagerstown-Martinsburg MD-WV nonattainment area; Wood County, part of the Parkersburg-Marietta WV-OH nonattainment area; and Marshall County and Ohio County, part of the Wheeling WV-OH nonattainment area, hereinafter referred to in this notice as the West Virginia portions of the Hagerstown-Martinsburg, Parkersburg-Marietta, and Wheeling PM<INF>2.5</INF> nonattainment areas. This proposed determination is based upon quality assured, quality controlled, and certified ambient air monitoring data that show that these areas have monitored attainment of the 1997 PM<INF>2.5</INF> NAAQS based on 2006- 2008 data. In addition, quality controlled and quality assured monitoring data for 2009 that are available in the EPA Air Quality System (AQS) database, but not yet certified, show these areas continue to have clean data for the 1997 PM<INF>2.5</INF> NAAQS. If this proposed determination is made final, the requirements for these areas to submit an attainment demonstration, associated reasonably available measures, a reasonable further progress plan, contingency measures, and other planning State Implementation Plans (SIPs) related to attainment of the standard shall be suspended for so long as the area continues to meet the 1997 PM<INF>2.5</INF> NAAQS. | 2009-07-31 | 2009 | 7 | https://www.federalregister.gov/documents/2009/07/31/E9-18393/approval-and-promulgation-of-air-quality-implementation-plans-west-virginia-determination-of-clean | https://www.govinfo.gov/content/pkg/FR-2009-07-31/pdf/E9-18393.pdf | Environmental Protection Agency | 145 | EPA is proposing to determine that the West Virginia portions of three nonattainment areas for the 1997 fine particulate (PM<INF>2.5</INF>) National Ambient Air Quality Standard (NAAQS) have clean data for the 1997 PM<INF>2.5</INF> NAAQS.
