Abstract
EPA is making a final determination regarding the Harrisburg- Lebanon-Carlisle-York, Allentown, Johnstown, and Lancaster nonattainment areas (hereafter referred to as ``Areas'') for the 24- hour 2006 fine particulate matter (PM<INF>2.5</INF>) national ambient air quality standard (NAAQS). EPA is determining that the Areas have clean data for the 24-hour 2006 PM<INF>2.5</INF> NAAQS. These determinations are based upon complete, quality-assured, quality- controlled, and certified ambient air monitoring data showing that these Areas have monitored attainment of the 24-hour 2006 PM<INF>2.5</INF> NAAQS based on the 2008-2010 data in EPA's Air Quality System (AQS) database. EPA's determinations relieve these Areas from the requirements to submit an attainment demonstration, associated reasonably available control measures, a reasonable further progress plan, contingency measures, and other planning State Implementation Plans (SIPs) related to attainment of the standard for so long as these Areas continue to meet the 24-hour 2006 PM<INF>2.5</INF> NAAQS.
