INTRODUCTION 

 The air quality modeling results for the 12-kilometer (km) grid modeling domain are presented in 

this appendix for the attainment demonstration for the Charlotte-Gastonia-Rock Hill, NC-SC 8-hour ozone 

nonattainment area (referred to as the Metrolina area). These modeling results are displayed as daily

maximum 8-hour ozone plots for both the 2002 baseline year and the 2009 attainment year. Only the 

modeling days that were used in determining the relative reduction factors (RRFs) at any of the Metrolina 

area ozone monitors are presented here. The color scale used for these plots are based on the Air Quality 

Index (AQI) where orange and red colorations indicate modeled exceedances of the 8-hour ozone National

Ambient Air Quality Standard. 

 Each of the following pages presents a single modeling day. The first or top plot on each page is the 

daily maximum 8-hour ozone plot for the 2002 baseline year. The second or bottom plot is the daily 

maximum 8-hour ozone plot for the 2009 attainment year. The comparison of the of the attainment year plot 

to the baseline year plot determines the relative reduction for each of the RRF days in this attainment 

modeling exercise. 

 A table is presented immediately below the plots to 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 for a 

domain mask that represents the Metrolina nonattainment 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.
