A request for public hearing, in accordance with 40 CFR 51.102, and the public comment period were noticed in the local ne wspapers on Friday, October 30, 2009. The public comment period was open from October 30, 2009 , through December 7, 2009, with a tentative hearing scheduled for Monday, December 7, 2009. No request for public hearing was received and the hearing was cancelled. A hearing can cellation notice was posted on the North Carolina Division of Air Quality (NCDAQ) website on Wednesday, December 2, 2009. The public comment period elicited comments from the USEPA.

Background

The Hickory and Triad areas North Carolina, located in Catawba, Davidson, and Guilford counties, was designated nonattainment for the annual PM 2.5 National Ambient Air Quality Standard (NAAQS) on January 5, 2005 (70 Federal Register 944) and became effective on April 1, 2005. The nonattainment designation was an action taken by the USEPA under Section 107(d) of the Clean Air Act (CAA). The CAA requires that some area be designated as
nonattainment if a monitor is found to be in violation of the NAAQS. The USEPA took designation action in 2005 based on the ambient data from 2001- 2003. At that time, the design values for the Hickory and Triad nonattainment areas were 15.6 μg/m 3 and 15.9 μg/m 3

, respectively.

All violating monitors we re attaining the annual PM 2.5 standard with the inclusion of the 2008 ambient data. The 2006-2008 design values for th e Hickory and Triad nonattainment areas are 14.2 μg/m 3 and 14.5 μg/m 3 , respectively. Both areas continue to attain the daily PM 2.5 standard. Therefore, the Hickory and Triad PM 2.5 nonattainment areas are in attainment of the annual

PM 2.5 NAAQS and eligible to be consider ed for redesignation to attainment.
