1 INTRODUCTION 

This document is a supplement to the June 15, 2007 attainment demonstration State Implementation 

Plan (SIP) submittal (re-submitted on November 12, 2009) which addresses the additional weight of 

evidence information requested by the United States Environmental Protection Agency (USEPA). 

The USEPA has requested supplemental information since the Metrolina nonattainment area did not 

have a three-year design value below the 1997 8-hour ozone standard for the three-year period 

including the 2009 data, yet did have clean data for 2009, i.e., the fourth highest values at all of the 

monitors were below the 1997 8-hour ozone standard. The NCDAQ utilized 2011 modeling to 

support the June 2007 attainment demonstration SIP and to provide weight of evidence that the area 

will attain the standard with a one year extension of the attainment date to June 15, 2011. The 

NCDAQ applied the attainment test as outlined in the USEPA’s Guidance on the Use of Models 

and Other Analyses for Demonstrating Attainment of Air Quality Goals for Ozone, PM2.5 and 

Regional Haze, (referred to as Attainment Guidance) to the 2011 modeling results. 

This appendix includes the modeling results from the 2011 modeling supporting Metrolina 

attainment of the 8-hour ozone standard by June 15, 2011. Model attainment test results and 

additional modeling analysis is included. Attached to the appendix is a detailed display of the 2011 

modeling results comparable to Appendix K of the June 2007 attainment demonstration. 

2 MODELED ATTAINMENT TEST 

The modeled attainment test is the practice of using an air quality model to simulate baseline (i.e., 

current) and future air quality. For the 8-hour ozone NAAQS, the baseline and future model 

estimates are used in a “relative” rather than “absolute” sense. Specifically, the ratio of the air 

quality model’s future to baseline predictions is calculated at each ozone monitoring site. These 

monitoring site-specific ratios are called relative response factors (RRF). Future ozone design 

values (DVF) are then estimated at each monitor by multiplying the monitor-specific baseline ozone 

design value (DVB) by the modeled relative response factor for each monitor. If the resulting 

predicted site-specific DVFs are < 82 parts per billion (ppb), a clear demonstration of predicted 

attainment is shown. If the predicted DVFs are > 82 ppb and < 87 ppb, then a weight of evidence 

demonstration must be submitted that supports a demonstration of attainment. For DVFs > 87ppb, 

the Attainment Guidance states that more qualitative results are less likely to support a conclusion 

differing from the outcome of the modeled attainment test. Equation 2-1 presents the modeled 

attainment test, applied at monitoring site “x” as described in Section 4.0 of the Attainment 

Guidance. 

 (DVF) = (RRF) x (DVB) Equation 2-1 

Where (DVB) = the baseline design value monitored at site "x", ppb 

 = the average (of the three) design value periods which include the baseline 

inventory year (i.e. the average of the 2000-2002, 2001-2003, and 2002-2004 

design values periods for the 2002 baseline inventory year). 
Modeling Results 2 

Supplement to the Attainment Demonstration for the Appendix D 

Charlotte-Gastonia-Rock Hill, NC-SC 8-Hour Ozone Nonattainment Area April 5, 2010 

 (RRF) = the ratio of the future 8-hour daily maximum concentration predicted "nearby" a 

monitor (averaged over each day of the episode) to the current 8-hour daily 

maximum concentration predicted "nearby" the monitor (averaged over each day 

of the episode). 

 (DVF) = the estimated future design value, ppb. 

It is important to consider an array of cells “nearby” a monitor rather than focusing on the 

individual cell containing the monitor. This allows for variations in the model performance where 

the peak ozone may not occur in the grid cell that contains the monitor but rather nearby the 

monitor. Table 2-1 provides the USEPA's recommendations for defining “nearby” cells for grid 

systems having cells of various sizes. Since the modeling was performed using a 12-kilometer grid 

resolution, the size of the array for “nearby” cells was 3 x 3. 

Table 2-1 USEPA’s Recommendation for Defining “Nearby” Cells 

Size of Cell 

(km) 

Size of the Array of 

“Nearby” Cells 

<5 7 x 7 

>5-8 5 x 5 

>8-15 3 x 3 

>15 1 x 1 

The RRF is calculated by taking the ratio of the mean future year modeling 8-hour ozone daily 

maximum to the mean baseline year modeling 8-hour ozone daily maximum “near” the monitor. 

(Equations 2-2). 

RRF = mean future yr. 8-hr daily max “near” monitor “x” Equation 2-2 

 mean baseline yr. 8-hr daily max “near” monitor “x” 

Section 14.1.1 of USEPA’s Attainment Guidance outlines the process for determining which days 

are used in the RRF calculation. The day selection process starts by identifying all the days in the 

baseline modeling that has a modeled daily maximum 8-hour average ozone equal to or greater than 

85 ppb. If there are 10 or more days greater than 85 ppb, then 85 ppb is used as the cutoff with 

those days used in the RRF calculation. If there are fewer than 10 days with a modeled daily 

maximum 8-hour average ozone equal to or greater than 85 ppb, then the threshold is reduced by 1 

ppb until there are at least 10 days identified for use. If there are fewer than 10 days with a modeled 

daily maximum 8-hour average ozone equal to or greater than 70 ppb, then all days at 70 ppb and 

higher are used in the RRF calculation and consideration of modeling another episode should be 

explored. 

The DVB, for purposes of the modeled attainment test, is defined in the Attainment Guidance by 

one of four methods: 

1. The design value period (i.e. the average 4th highest value for the 3-year period used to 

designate an area “nonattainment”, for this nonattainment designation, the period from 2001 

to 2003) 
Modeling Results 3 

Supplement to the Attainment Demonstration for the Appendix D 

Charlotte-Gastonia-Rock Hill, NC-SC 8-Hour Ozone Nonattainment Area April 5, 2010 

2. The average 4th highest value for the 3-year period straddling the baseline inventory year 

(e.g., the 2001-2003 design value period for the 2002 baseline inventory year) 

3. The highest of the three design value periods which include the baseline inventory year (e.g., 

the 2000-2002, 2001-2003, 2002-2004 design value periods for a 2002 baseline inventory 

year) 

4. The average of the three design value periods which straddle the baseline inventory year 

(e.g., the average of the 2000-2002, 2001-2003, and 2002-2004 design value periods for a 

2002 baseline inventory year) 

The USEPA recommends the fourth method (average of the three design value periods straddling 

the baseline year), which is the DVB shown in Table 2-2 at each ozone monitoring site in the 

Metrolina region. 

Table 2-2 also lists the modeling results for 2011 by monitor in the Metrolina area. In the tables, 

the first column is the monitoring site, then the county of the monitoring site’s location, followed by 

the DVB used for the attainment test. The next series of columns are the number of days used in the 

calculation, the ozone level threshold needed to reach at least 10 days for RRF, the calculated RRF, 

and finally the resulting DVF for the 2011.

As can be seen in the table above, all monitors in the Metrolina area have predicted design values 

below the standard. These results support NCDAQ’s assertion that the air quality is expected to 

continue to improve as the NOx emissions continue to decline from the point and mobile sources. 

These results provide additional weight of evidence that the area will attain the 1997 8-hour ozone 

standard by June 15, 2011. 

3 ADDITIONAL AIR QUALITY MODELING ANALYSIS 

In Section 7.0 of the Attainment Guidance, various aspects of air quality models, modeled 

performance, and uncertainties associated with the length of modeled episodes and limited 

observational datasets are described. A series of three additional air quality modeling outputs or 

metrics is recommended to provide assurance the modeled demonstration indicates attainment. 
Modeling Results 4 

Supplement to the Attainment Demonstration for the Appendix D 

Charlotte-Gastonia-Rock Hill, NC-SC 8-Hour Ozone Nonattainment Area April 5, 2010 

These metrics look at the relative change between the baseline and future years modeling and help 

to demonstrate how widespread the improvement in air quality is expected to be in the future. 

Although the final guidance did not recommend percentage cut points that corresponds to 

supportive weight of evidence, an earlier draft version of the Attainment Guidance recommends that 

the metrics should be at least 80% or higher. 

As described in Section 7.1 of the Attainment Guidance, the modeling data for the area displayed in 

Figure 3-1 from the 2002 and 2011 modeling were applied to the following metrics: 

1. Relative change in surface grid-hours greater than 84 ppb. This metric is termed 

Persistence-Hour and is defined as the number of grid-cells in a given region with 

predicted hourly 8-hour ozone concentrations greater than 84 ppb. The relative change in 

Persistence-Hour is presented as a percent reduction computed for the modeling period 

May through September from the baseline year case to the future year case. 

2. Relative change in the number of grid cells with predicted 8-hour daily maxima greater 

than 84 ppb. This metric is termed Persistence-Daily metric and is similar to 

Persistence-Hr, but uses the modeled daily maximum 8-hour ozone concentrations 

greater than 84 ppb instead of the hourly 8-hour ozone concentrations. The relative 

change in Persistence-Daily is also presented as a percent reduction computed for the 

modeling period May through September from the baseline year case to the future year 

case. 

3. Relative change in the sum of hourly predictions greater than 84 ppb. This metric is 

termed Severity-Hour and is defined as the sum of all grid-cells with predicted hourly 8-

hour ozone concentrations greater than 84 ppb. Given the definition of Persistence, this 

Severity could be considered as a weighted form of the Persistence metric. The relative 

change in Severity is also presented as a percent reduction computed for the modeling 

period May through September from the baseline year case to the future year case. 

In addition to the three recommended metrics, two additional metrics were computed to create a 

comprehensive corroborative analysis. The two additional metrics are: 

4. Relative change in the sum of the predicted 8-hour daily maxima greater than 84 ppb. 

Severity-Daily metric is similar to Severity-Hour, but uses the modeled daily maximum 

8-hour ozone concentrations greater than 84 ppb instead of the hourly 8-hour ozone 

concentrations. The relative change in Severity-Daily is also presented as a percent 

reduction computed for the modeling period May through September from the baseline 

year case to the future year case. 

5. Air Quality Index (AQI) counts. The AQI Counts metric is a count of the number of 

grid-cells with predicted maximum 8-hour ozone concentrations sorted within each of 

the Code Green, Yellow, Orange and Red categories, as defined by the USEPA's AQI 

Index. As with the persistence and severity metrics, the AQI counts metric can be 

applied to both hourly and daily maximum 8-hour ozone concentrations. AQI Counts 

are presented as percentages of the total number of grid-cells within the study region.

The metrics described above were applied to the modeling results for just of the nonattainment area. 

Below is the region for which this modeling data was extracted for the 2002 baseline and the 2011 

modeling runs. 

Figure 3-1 Area for which the air quality metrics were applied. 

The results from each of the five air quality modeling metric calculations demonstrated significant 

reductions of greater than 90% in the 2011 future year air quality modeling for days that modeled 

above the NAAQS in the Metrolina nonattainment area. Each metric demonstrated substantial 

reductions for 2011. It is important to note that the relative reductions in all metrics well surpassed 

the draft version of the Attainment Guidance recommendation of 80% for these particular 

calculations. 

Figure 3-2 presents the relative reductions calculated in the first four metrics described above. The 

left 2 bars are the Persistence-Hour and Persistence-Daily reductions, and the right 2 bars are the 

Severity-Hour and Severity-Daily reductions. The 2011 modeling results demonstrate a 97.4% 

reduction in persistence of hourly maximum ozone and 95.9% reduction in persistence of daily 

maximum ozone. The severity reductions for 2011 are equally on a similar scale of 97.5% and 

96.1% reduction for hourly and daily maximum ozone, respectively.

Equating the 95.9% relative reduction in the daily maximum ozone persistence to AQI counts, 

Figure 3-3 demonstrates a drop from 317 grids cells in the Code Orange and Red levels in 2002 

baseline modeling to only 13 grid cells in 2011 future modeling. Additionally, the number of grid 

cells Code Yellow and greater is reduced by 65.0% from 3,503 grid cells in 2002 to 1,227 grid cells 

in 2011.

reduction from 23,336 to 5874. This is a 74.8% reduction from 2002 to 2011.

The tremendous improvements in air quality from the 2002 baseline modeling to the 2011 modeling 

can further be illustrated by looking at just the percentage of occurrence of the Code Yellow and 

Orange grid cells throughout the Metrolina area. Figures 3-5 and 3-6 present these metrics for 2011 

in terms of the daily and hourly percentage of occurrence, respectively.

Finally, all of the AQI grid cell counts used throughout this section and displayed in Figures 3-3 

through 3-6 are summarized below. Table 3-1 contains all of the grid cell counts for both the 

Hourly and Daily AQI count analyses for the 2002 and 2011 modeling. 

Table 3-1 Total number of grid cells for the AQI Categories 2002 vs 2011. 

The air quality modeling metric analyses for the Metrolina nonattainment area demonstrates relative 

reductions well beyond the recommended 80% mark that is considered appropriate for concluding 

that a proposed strategy would meet the 8-hour ozone NAAQS. 

The NCDAQ believes that the supplemental analysis provided in this section is further evidence 

that the Metrolina nonattainment area will attain the 8-hour ozone NAAQS by June 15, 2011.

Introduction 

The 2011 air quality modeling results for the 12-kilometer (km) grid modeling domain are 

presented below for the Supplement to the June 15, 2007 submitted North Carolina 8-Hour Ozone 

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 a 

series of daily maximum 8-hour ozone plots for the 2011 modeling. Only the 34 modeling days that 

were used in determining the relative response factors (RRFs) at any of the Metrolina area ozone 

monitors are presented here. The 2002 modeling plots can found Appendix K of the referenced 

June 15, 2007 attainment demonstration. 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. 

A table is presented to further detail the change in number of grid cells between the respective AQI 

color codes from 2002 to 2011. 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. 

Figure 1 Metrolina Nonattainment Area Domain Mask 

A second table is included below each modeling day to list the monitors that use that particular day 

in their respective RRF calculation for 2011. The comparison of the of the 2011 modeling plots to 

the respective 2002 modeling plots determines the relative response for each of the RRF days. 

After all 34 modeling days are presented, a series of RRF summary tables are included. Table 36 

summarizes the days used in the monitor specific RRF calculation for the 2011 modeling. This 

summary table redisplays the information already presented in the second table found after each of 
2011 Modeling Results 2 

Supplement to the Attainment Demonstration for the Appendix D.1 

Charlotte-Gastonia-Rock Hill, NC-SC 8-Hour Ozone Nonattainment Area April 5, 2010 

the modeling day plot pages for convenience. The 2011 based daily RRF calculations are 

summarized in Table 37and use the day specific maximum 8-hour ozone concentration modeled 

near each ozone monitor from the 2002 modeling (Table 38) and the 2011 modeling (Table 39). 

It should be noted that a minor alteration in the spatial distribution of the emissions inventory in the 

2011 air quality modeling required a rerun of the air quality model for the 2002 baseline year to 

appropriately calculate the 2011 based RRFs without introducing any modeling bias due to the 

minor emissions inventory spatial distribution alteration. These differences were so minor that the 

second or revised set of 2002 modeling day plots was not included in this attachment as the spatial 

pattern and magnitude of ozone concentrations were generally indistinguishable to the 2002 plots 

already displayed throughout the referenced Appendix K.
