### EXECUTIVE SUMMARY

Air quality modeling of the ch anges in stack emissions and parameters to support the permitting of a Dry FGD (DFGD) System and the installation of Low NOx Burners and an Overfire Air System (LNB/OFA) at th e Southwestern Electric Power Company’s Flint Creek Plant near Gentr y, Arkansas was conducted. This work was done using the current versions of the USEPA prefe rred model AERMOD and its meteorologic preprocessor AERMET and terrain preprocessor AERMAP. The modeling exercise was performed in accordance with the modeling protocol and USEPA Guidelines.

The summary results of this modeling are s hown in Table ES-1. This table shows the parameter, peak modeled value, and Signi ficant Impact Level (SIL). The National Ambient Air Quality Standard (NAAQS) colu mn is shown for purposes of the lead modeling analysis since there is no SIL for lea d. From this table we see that all of the peak changes in ambient concentrations due to the installation of the DFGD and LNB/OFA systems at Flint Creek are below th e SIL values and considered insignificant changes under USEPA Modeling Guidance. Therefore, this m odeling demonstration shows that there will be no adverse ambient impacts from the changes in stack emissions and parameters attributable to the installa tion of the DFGD and LNB/OFA systems at the modeled emission rates.

### INTRODUCTION

In order to comply with the requirements of the Federal and State Best Available Retrofit Technology (BART) Rules, Southwestern Electric Power Company (SWEPCO) has elected to install a Dry FGD (DFGD) system and new Low NO x Burners with Overfire Air on its Flint Creek Plant located near Gent ry, Arkansas. This document reports the air quality modeling analyses conducted on the stack emissions from the plant.

The results of this modeling analysis indicate that the impacts from the stack emissions due to changes in the stack characteristics and emissions changes attributable to the DFGD and LNB/OFA installation do not re sult in significant increases in ambient impacts from the plant.



### STACK PARAMETERS, EMISSION S, AND FACILITY LAYOUT

Emissions and stack data used in this mode ling are shown in Table 1. The current design calls for reuse of the existing stack; theref ore the stack coordina tes will not change between the existing and scrubbed cases. The existing full load exit velocity and temperature is based on the 2008 Part 75 Fl ow RATA performed on November 11, 2008. This was the only load tested during this RATA . The flow for the existing low load case is based on a temperature adjusted design flow from the low load Dry FGD (DFGD) Case. The full and low load DFGD Cases ar e based on design information from the technology supplier available at the time of protocol development. The mid load cases for both the existing and DFGD cases are interp olated as being half way between the full and low load cases.

SO 2 emissions for the existing cases are ba sed on the NSPS limit of 1.2 lb/MMBtu and the control cases are based on the presumptive BART SO 2 limit of 0.15 lb/MMBTU for the FGD cases. NO x emissions are similarly developed using the NSPS limit of 0.7 lb/MMBtu for the existing cases and the presumptive BART NO x limit of 0.23 lb/MMBtu for the control cases. Presumptive BART was selected for the SO 2 and NO x emissions in the control case since permitting has not begun at the time of the modeling and any limit ultimately issued would be no higher than the modeled values. This adds conservatism to the estimated ambient impacts of the post change case should lower emission limits ultimately be imposed through the permitting process.

CO is anticipated to increase as a result of the installation of the new Low NOx Burner/ Overfire Air (LNB/OFA) System from the cu rrent full load permit limit of 822.3 lb/hr or 0.13 lb/MMBtu to 0.15 lb/MMBtu or 948.6 lb/hr. It is not anticipated that the installation of the DFGD system will result in the change of emissions for any other permitted pollutant. The total particulate emissions , are based on a 0.123 lb/MMBtu emission rate which includes the primary particulate lim it of 0.1 lb/MMBtu plus and allowance of 0.023 lb/MMBtu for condensible particulates, and lead which will be modeled based on aFlint Creek Dry FGD Installation Modeling Report January 27, 2010 2 full load emission limit of 0.082 lb/hr for both cas es. These values will then be scaled to develop the lower load emission estimates shown in Table 1.

In order to properly determine if downwash w ill be used in any of the calculations on the main stack the USEPA Building Profile Input Program (BPIP) was used. The plot plan showing the plant and the known locations for the major equipment in the DFGD System is shown in Figure 1. The equipment shown inside the bubble to the southeast of the electrostatic precipitator was not entered into BPIP since that equipment has not been designed at the time of this exercise and th e exact locations of the equipment and its dimensions are not available. Based on the BPIP analysis, the Good Engineering Practice Stack Height (GEP Stack Height ) is 513 feet, which is less than the actual stack height of 540 feet. The GEP Stack Height shown in Ta ble 1 reflects the BPIP determined height and not the actual stack height.

Since the modeled stack height is at or above the calculated GEP Stack Height, it is not necessary to include building profile information in this case. However, the windFlint Creek Dry FGD Installation Modeling Report January 27, 2010 3 direction specific building dimensions were included in the modeli ng input files in the interest of completeness. The BPIP files used are included as part of the files supplied on the DVD in Appendix ___.

### TERRAIN AND RECEPTOR GRID

The data used in developing the receptor grid was obtained from the USGS Seamless Server referenced to the NAD 83 datum. Th e retrieved data was from the 1 arc second database, having a 30 meter resolution wh ich is suitable for this study.

The receptor grid was developed using AERM AP version 09040. The overall receptor grid runs from a southwest corner of 313000 easting by 3963400 northing in UTM Zone 15 to a northeast extent of 413000 easting by 4063400 northing. This overall grid contains an interior zone of 100 mete r receptors extending from 358000 easting by 4008400 northing to 368100 easting by 4018500 for a total of 10,400 receptors. The 100 meter grid is then surrounded by a 250 me ter grid extending out approximately 10 additional kilometers with an extent of 348000 easting by 39 98400 northing to 378250 easting by 4028650 northing generating 13203 recep tors with a spacing of 250 meters. Finally the overall grid is filled out with a co arse grid of 1 kilometer spacing resulting in an additional 9240 receptors with a spacing of 1 kilometer. The total number of receptorsFlint Creek Dry FGD Installation Modeling Report January 27, 2010 4 being modeled is 32847. Figure 2 shows the confi guration of this grid with the interior zone in a dark yellow representing the 100 me ter grid, the green zone representing the 250 meter receptors, and the blue zone repres enting the 1 kilometer receptors. The plant is denoted by the red dot roughly in the center of the 100 meter receptor grid zone. At the time the receptor network was designed, inform ation relating to the exact location of the plant fence line was not available, so the rem oval of receptors inside of the fenced portion of the SWEPCO property was not done. Theref ore all receptors were considered in the analysis of the modeling results.

An aerial phot ograph of the plant site is overlain on the terrain representation in the 100 meter receptor grid area and demonstrates that the stack location has been properly aligne d in the modeling grid since ot her notable feat ures in the photograph show good alignment with the terra in when the stack is placed at the indicated coordinates.

### METEOROLOGIC DATA SELECTED

The surface meteorologic data selected for this study was taken from the Automatic Surface Observation Station (ASOS) at the Northwest Arkansas Regional Airport near Bentonville, Arkansas. This data was se lected based on a review of the surface characteristics of the Flint Creek Plant site and the area surrounding the meteorologic instruments at the airport. Additional surf ace sites reviewed, but not deemed sufficiently representative of the Flint Creek Plant site due to excess urbanization near the meteorologic monitoring stations included Ft . Smith, Arkansas, Tulsa, Oklahoma, and Springfield, Missouri.

Following the selection of the Bentonville si te as the preferred source of surface meteorologic data, data covering the peri od January 1, 2003 at 0000 UTC to January 31 2009 at 2300 UTC was obtained in archived 3505 format from National Climatological Data Center (NCDC). This dataset typically reported three data lines per hour for the Bentonville ASOS site. This data was then examined to determine its completeness. This examination revealed that the da ta from 2003 through 2005 and 2007 through 2008 was sufficiently complete to be used. However, the data for the year 2006 was rejected due to a gap in the data set from 050 0 UTC on March 13 to 1635 UTC on July 19. Therefore, the five years of meteorologi c data used in this study are 2003, 2004, 2005, 2007, and 2008.

Upper Air data was obtained for the same years as the surface data from the NOAA/ERSL Radiosonde Database 1 for the Springfield, Missouri radiosonde site. This site was selected as being climatologically representative of the Flint Creek Plant site and is sufficiently complete to allow processing of the selected years of surface data.

The data was ultimately processed into m odel ready form using AERMET version 06341. The surface parameters used in the Stage 3 processing of AERMET were developed for the Bentonville surface site using the AERS URFACE preprocessor over a 1 kilometer radius divided into eight 45 degree sectors. Due to format issues with the NCDC archived 3505 data and the inability of AERM ET to accept this specific version of the 3505 format, an additional step was taken prior to the exercising of AERMET. This step used a program developed by Russell Lee 2 and made freely available on his web site to convert the archived 3505 format data into SAMSON format da ta, select a single value to represent the hour in those hour s where more than one value exists, and to convert the alpha descriptors for cloud cover into nume rical values that AERMET can handle. The conversion process for the alpha cloud cover descriptors is documented by Lee in a 2003 paper “Using the New ISHD Format Meteorol ogical Data in the Lakes Environmental RAMMET View and AERMET View” 3 . Following checking, the data from this process

The upper air data required no supplemental processing for use in the AERMET processor.



### MODELING RESULTS

AERMOD version 09292 was used for the modeling exercise. A combined simulation was run for each year for SO 2 , NO x , and PM due to the similarity in needed output. Lead emissions were simulated separately due to the need to obtain monthly averages by receptor, and CO was simulated separately due to the need to obtain 1 hour and 8 hour

averages.

For all pollutants except lead, results were out put for the requisite averaging times shown in Table 2 for the differences between the ba se case and the control case as well as the concentrations for the control case. Plot f iles of the peak differences and of the high second high values for the appr opriate averaging times.

Lead results were output for the control case on ly since there is no anticipated change in the emission rate and the only variable to be evaluated was the control case against the new standard. Monthly data was output into an analysis file by receptor by month and evaluated using a set of three Ex cel files. The analysis of th e Lead data is described in more detail in the following section descri bing the results of the lead simulations.

The following sections discuss the results for each pollutant individua lly. The red values in the respective tables denote the critical regulatory values for each pollutant and averaging time. Unless denoted by a letter follo wing the value, all values in the tables in the following sections are based on full load operating conditions. Where some values were obtained from cases other than full load, the load case for a given year is denoted by the use of F for full load, M for mid-load, and L for low load operating conditions.Flint Creek Dry FGD Installation Modeling Report January 27, 2010 8 SO 2

Ambient SO 2 concentrations modeled with the in stallation of the DFGD System showed a slight increase in the three and 24 hour c oncentrations over the existing case and no change to a decrease for the annual case. Th e peak changes are noted in red in Table 3. For the annual case, there were no receptors modeled that increased and the peak decrease was -3.74  g/m 3 observed in modeled year 2007. Table 3 shows the maximum annual change as 0.00  g/m 3 as the algorithm used in AERMOD reports the peak increase in concentration and not the peak decrease in those cases where all receptors show no change or a decrease in concentra tions. In all cases, the maximum modeled changes are below the SIL levels shown for SO 2 in Table 2; therefor e, no further detailed modeling evaluations of SO 2 are necessary under the modeling protocol or USEPA guidelines for conducting air quality analyses.

Table 3 also reports the peak High Second High modeled value for each year for the control case. These values demonstrate that the installation of the DFGD system will not cause a violation of the SO 2 standard as it exists at the tim e of this study. Further data generated in this study with respect to one hour concentrations suggests that the installation of DFGD on Flint Creek should allow it to meet USEPA’s proposal to revise the SO 2 standard into a 1-hour form. This conc lusion is based on the examination of the control case 1-hour Carbon Monoxide data, whic h was generated using an emission rate identical to the modeled SO 2 emission rate for the control case.

Figures 5, 7, and 9 show concentration change s with respect to the existing case across the entire domain for the annual, 3-hour, and 24-hour cases respectively. These figures show that the maximum change in concentration occurs cl ose in to the plant and the changes decrease in magnitude with distance. The changes noted at edge of the modeling domain are less than 1  g/m 3 in all cases. Since the maximum changes occur close in to the plant, Figures 6, 8, and 10 were generated to examine the spatial characteristics of the peak changes.

Figures 6, 8, and 10 overlay the 100 meter grid concentrations onto a photograph of the plant area that shows SWEPCO ow ned property. In all nearly all cases the peak values occur off SWEPCO property and in thos e cases where the receptor is on SWEPCO property, the location is not fenced off in a way that precludes public entrance. Therefore, the reported concentrations occu r in ambient air as defined by USEPA.Flint Creek Dry FGD Installation Modeling Report January 27, 2010 9 Table 3.

NO 2

Like SO 2 , Nitrogen Oxides will also be reduced as part of the overall project. In addition to the addition of the DFGD system, the boi ler is being retrofi tted with a modern LNB/OFA System. At a minimum, this syst em will achieve the presumptive BART limit for NO x identified in 40 CFR 51 Appendix Y of 0.23 lb/MMB that was used in the modeling analysis.

The modeling of this pollutant was conducted as total NO x and not as NO 2 . Under the provisions of the USEPA Guideline on Air Qual ity Modeling, it is permissible to adjust the reported NO 2 concentrations by a factor of 0.75, the national average NO 2 to NO x ratio 4 . Since the SIL for NO 2 is met without using the NO 2 to NO x ratio, this adjustment has not been applied to th e results shown in Table 4.

The current guidance for performi ng air quality analyses for NO 2 require only examining annual impacts. In this case the critical pa rameter for comparison to the SIL is the annual

For the analysis of the work planned for the Flint Creek Plant, there is no modeled increase in annual NO 2 concentration due to the project and the maximum decrease at tributable to the project is -1.38  g/m 3

. On January 25, 2010, the USEPA Assistant Admini strator for Air signed revisions to the National Ambient Air Quality Standard for NO 2 . This revision retains the annual standard analyzed above and adds a 1-hour standard at a level of 188  g/m 3 (100 ppb) based on the three year average of the 98 th percentile value. At this time USEPA has not issued and guidance on how to analyze this new standard as part of the permitting process. In order to obtain a preliminary examination of what if any impact this new standard will have on this project, an ex amination of the 1-hour results from CO was again undertaken. When the HSH data for the 1-hour CO modeling was adjusted to reflect the 0.23 lb/MMBtu em ission rate used in the NO x modeling, the ad justed peak 1- hour HSH value becomes 98.5  g/m 3 and the highest 3 year average value of these 1- hour high second high values is 84.35  g/m 3 . These values, calculated using the high second high values instead of the 8 th high value indicated by the 98 th percentile value in the new standard, are approxi mately half of the newly promulgated standard, which indicates that the proposed project should be protective of the 1-hour NO x ambient standard. These estimated values assume all of the emitted NO x is NO 2 and do not reflect the adjustment f actor described above.

Carbon Monoxide (CO) is likely the only true Prevention of Significant Deterioration (PSD) pollutant in this analysis due to the installation of the LNB/OFA equipment as part of this project. The consideration of th e actual increase in a nnual emissions that may create the need for a full PSD analysis a nd a Best Available C ontrol Technology (BACT) analysis will be discussed in the permit application portion of this submittal. The air quality modeling analysis porti on of the application assumes that the CO hourly emission rate will increase by 126.3 lb /hr at full load.

Table 5 shows the difference in ambient concen trations due to the in crease of 126.3 lb/hr. All values shown in Table 5 were generated by the full load case as that case resulted in the maximum increases in ambient concentratio ns from the three cases examined. All of these values are below the SIL, therefore, under USEPA modeling guidelines the CO impacts are considered insignificant a nd further analysis is not required.

Figures 13 and 14 show the 1 hour difference patterns for the year 2008, the year containing the peak 1-hour change. Figure 13 shows the pattern of 1 hour changes over the entire 50 kilometer modeling domain and Fi gure 14 shows the detail of the fine grid overlaid on a photo of the plant si te. The peak change is locat ed to the west of the plant across the lake off of SWEPCO property.

Figures 15 and 16 show the 8 hour difference patterns for the year 2004, which had the peak 8 hour change. Figure 15 shows the pa ttern of 8 hour change s over the entire 50 kilometer modeling domain and Figure 16 shows the detail of the fine grid overlaid on a photo of the plant site. The peak 8 hour change is located to the north east of the plant off of SWEPCO property.

Particulate matter of all sizes is the only stac k emitted pollutant with an SIL that is not expected to experience a change in emission levels attributable to the project. As modeled, the particulate emission rate assumes that the primary particulate emissions are all PM10 and a small allowance over the primar y particulate emission limit is added to account for condensible particulat e that will form from gaseous constituents in the flue gas to allow a reasonable estimation of the overall impact from the particulate stack emissions.

In examining the results in Table 6, both th e 24-hour and annual peak differences are below the SIL values. The critical differences are highlighted in red in Table 6 and all of the values shown occurred dur ing the full load operating cas es. Locationally, the peaks are to northeast of the stack outside of the fe nced portion of the Flin t Creek Plant site and generally off of SWEPCO property as shown in Figures 16, 18, and 20 below. Therefore, particulate matter will not need a detaile d analysis under USEPA modeling guidance.

Lead

Unlike the preceding pollutants evaluated, lead does not have an SIL. As described in the protocol the evaluation of the 2008 revision to the lead ambient standard was performed using an Excel spreadsheet in the following fashion:

As described in the protocol, the initial evaluation for complian ce with the 2008 revision to the lead ambient standard used the follo wing technique. Three month rolling averages of peak monthly averages were genera ted starting with March 2003 and continuing forward to the December 2005 three month averag e. Due to the missing data issue with 2006, three month averages will be picked up again with the March 2007 value and continued through the December 2008 three month average. When this technique was used, the peak 3 month period occurred during June, July and August 2008, which generated an overall average of 0.000187  g/m 3 calculated without regard to the receptors from which each monthly average originated. This value is several orders of magnitude less than the ambient standard which is 0.15  g/m 3 on a rolling 3 month

average.

Since the data was loaded into a spreadsheet by receptor, it was not difficult to extend the analysis to a receptor by receptor basis. The result of this analysis was that the peak rolling 3 month average was 0.000177  g/m 3 during the period of June, July, and August 2008. This value occurred at two adjacent receptors located at 363800 and 363900Flint Creek Dry FGD Installation Modeling Report January 27, 2010 23 easting by 4014600 northing in both cases. These receptors are to the northeast of the plant off of SWEPCO property. This value is again several orders of magnitude lower than the revised ambient standard.

Taken together, both of these analyses demons trate that the changes in stack parameters at Flint Creek will not result in an ambient l ead concentration attributable to Flint Creek Plant that would cause or contribute to a violation of the NAAQS for lead.



### CONCLUSION

Based on the results of this modeling exerci se, all stack based pollutants demonstrate changes in ambient concentra tions that are less than the Significant Impact Levels identified in Table 2 or in the case of lea d, orders of magnitude less than the ambient standard. The modeling study also examined the newly promulgated 1-hour NAAQS for NO 2 using available 1-hour high second high data . This examination demonstrated that using values far above the 98 th percentile values specified in the new 1-hour NAAQS for NO 2 resulted in modeled concentrations far below the level of the new standard. Ambient impacts from lead emissions at Flin t Creek were also examined using the proper form of the recently promulgated lead standa rd. These results indicated that the peak modeled impacts from stack emissions of lead were orders of magnitude less than the level of the new standard.

Therefore, from an air quality impact pers pective permitting the installation of a DFGD system and an LNB/OFA System at Flint Cree k Plant will result in insignificant changes in ambient impacts attributable to the stack emissions.Flint Creek Dry FGD Installation Modeling Report January 27, 2010 24
