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 31 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.
