## Introduction

The air quality modeling results for the 12-kilomete r (km) grid modeling domain are presented in this appendix for the attainment demonstration for both the Hickory and the Greensboro-WinstonSalem-High Point (referred to as the Triad area) annual fine part iculate matter (PM25) nonattainment areas. These modeling results are displayed as 24-hour average plots of reconstructed PM25 for both the 2002 baseline year and the 2009 a ttainment year.

A subset of days from 2002 is presented in th is appendix, though all days from 2002 are used in developing the relative reduction fact or (RRF) and subsequently the fu ture design value (DVF). For model performance evaluation, the USEPA’s “Guidan ce on the Use of Models and Other Analysis for Demonstrating Attainment Goals for Ozone , PM25, and Regional Haze” suggests looking at days with an daily average PM25 concentrati on greater than 65 micr ograms per meter cubed ( μ g/m^3). However, neither the Hickory nor th e Triad PM25 nonattainment area has any observed values greater than or equal to 65 μ g/m^3. This lead the North Carolina Division of Air Quality chose to use a cut off of 30 μ g/m^3 at any of the monitoring sites in either nonattainment area, as an initial method to select days for examination in the model performance eval uation and in the results section.

To ensure at least four days from each quarter we re presented, PM25 values form each quarter were ranked, and the four days with the highest average daily values in each quarter were also chosen. This selection process identified 28 days for presentation in this appendix, and examination in the model performance evaluation (Appe ndix J). The selected days are presented in Table 1 below.

Each of the following 28 pages presents a single mode ling day. The first or top plot on each page is the daily average PM25 plot for the 2002 baseline year. The sec ond or bottom plot is the daily average PM25 plot for the 2009 attainment year. The comparison of the of the attainment year plot to the baseline year plot determines the rela tive reduction for each of the RRF days in this attainment modeling exercise.

A table is presented immediately be low the plots to further detail the change in number of grid cells between ranges approximating the AQI color code s for the daily PM25 standard from 2002 to 2009. The grid cell counts are only cal culated for a domain mask that represents the Hickory and Triad nonattainment areas. A statewide view of this doma in mask is presented in Figure 1, with a closer view presented in Figure 2.

Finally, a table is included at th e bottom of each page that lists the observed monitor values from that particular day. Gray cells i ndicate days in which the sites had no observed value. Observations can be missing due to the sampling frequency of the si te (every day versus every third day) or the monitor was off line for repairs.Modeling Results 2 The Hickory And Greensboro-Winston Salem-High Point, NC PM2.5 Appendix K North Carolina Attainment Demonstration August 21, 2009 Table 1: Days selected for model evaluation a nd the observed value at each of the monitoring
