INTRODUCTION

The air quality modeling results for the 12-kilome ter (km) grid modeling domain are presented in this appendix for the attainment demonstration for the Charlotte-Gastonia-Rock Hill, NC-SC 8-hour ozon e nonattainment area (referred to as the Metrolina ar ea). These modeling results are displayed as daily maximum 8-hour ozone plots for both the 2002 baseli ne year and the 2009 attainment year. Only the modeling days that were used in determining the rel ative reduction factors (RRFs) at any of the Metrol ina area ozone monitors are presented here. The color scale used for these plots are based on the Air Qua lity Index (AQI) where orange and red colorations indica te modeled exceedances of the 8-hour ozone National Ambient Air Quality Standard.

Each of the following pages presents a single mode ling day. The first or top plot on each page is th e daily maximum 8-hour ozone plot for the 2002 baseli ne year. The second or bottom plot is the daily maximum 8-hour ozone plot for the 2009 attainment y ear. The comparison of the of the attainment year plot to the baseline year plot determines the relative r eduction for each of the RRF days in this attainmen t modeling exercise.

A table is presented immediately below the plots t o further detail the change in number of grid cells between the respective AQI color codes from 2002 to 2009. The grid cell counts are only calculated fo r a domain mask that represents the Metrolina nonattain ment area. This domain mask is presented in Figure 1 below.

Finally, a table is included at the bottom of each page to list the monitors that use that particular day in their respective RRF calculation. A summary of all RRF days is supplied at the end of the appendix in Table 33.
