# I 1. EXECUTIVE SUMMARY 

# I 1.1 BACKGROUND 

# I OnJuly 1, 1999, the U.S. Environmental Protection Agency (EPA) published the final Regional Haze 

# I Rule (RHR). The objective ofthe RHR is to improve visibility in 156 specific areas across the United States, known as Class I areas. The Clean Air Act defines Class I areas as certain national parks (over 6,000 acres), wilderness areas (over 5,000 acres), national memorial parks (over 5,000 acres), and international parks that were in existence on August 7, 1977. 

# I OnJuly 6, 2005, the EPA published amendments to its 1999 RHR, often called the BARTrule, which included guidance for making source-specific BestAvailable Retrofit Technology (BART) determinations. The BARTrule defines BART-eligible sources as sources thatmeet the following 

# I criteria: (1) 

### Have potential emissions ofat least 250 tons per year ofa visibility-impairing pollutant, 

# I (2) Were "inexistence"between August 7, 1962 and August 7, 1977, and (3) Are listed as one ofthe 26 listed source categories in the guidance. 

# I A BART-eligible source is not automatically subject to BART. Rather, BART-eligible sources are subject-to-BART ifthe sources are "reasonably anticipated to cause or contribute to visibility impairment in any federal mandatory Class I area." EPA has determined that sources are reasonably 

# I anticipated to cause or contribute to visibility impairment ifthe visibility impacts from a source are greaterthan 0.5 deciviews (dv) when compared against a natural background. 

# I Air quality modeling is the tool that is used to determine a source's visibility impacts. States have the authority to exempt certain BART-eligible sources from installing BARTcontrols ifthe results ofthe dispersion modeling demonstrate that the source cannot reasonably be anticipatedto cause or 

# I contribute to visibility impairment in a Class I area. Further, states also have the authority to define the modeling procedures for conducting modeling related to makingBART determinations. 

# I To promote consistency between states in the development ofBARTmodeling protocols and to harmonize the approaches between adjacent RPOs, CENRAP developed BARTModeling Guidelines 

# I (December 15,2005). The intent ofthe guidelines is to assist CENRAP states and source operators in the development ofstatewide and source-specific modeling protocols. 

## 1.2 OBJECTIVE 

# I The objective ofthis document is to provide a report summarizing the model results and the modeling 

# I methods and procedures that were followedby Trinity when conductingrefined modeling for Oklahoma Gas & Electric's (OG&E) Horseshoe Lake Generating Station near Harrah, OK.

I 1.3 LOCATION OF SOURCES AND RELEVANT CLASS

## I AREAS 

# I I OG&E's Horseshoe Lake station is located due north ofHarrah, OK, and is a PSD major source of emissions. The facilityis an electricity generating station and operates mUltiple natural-gas fired utility boilers. OG&E has identified the sources listed in Appendix A at the Horseshoe Lake station as sources that meet the three criteria for being BART-eligible sources. These sources include: 

# I

.. HL7, 2,379 MMBtu/hr Boiler, Babcock&Wilcox

.. HL8, 3,960 MMBtulhr Boiler, Combustion Engineering 

# I A detailed summary ofBART-eligibility is included in Section 4.1. Figure 1-1 provides a plot ofthe location ofthe Horseshoe Lake station in relation to its neighboring Class I areas. 

# I As required in CENRAP's BART Modeling Guidelines, Class I 

### areas within 300 km 

### ofthe plant were included in this screening analysis. The following Table contains the four surrounding Class I 

# I areas and the distances they are from the Horseshoe Lake station. As seen below, the Wichita Mountains NWR and Caney Creek Wilderness fall within this radius. 

# I Class I Area Name Distance from source (km) 1 

### Caney Creek Wilderness 300 Hercules-Glades Wilderness 398 

# I Upper Buffalo Wilderness 337 Wichita Mountains National Wildlife Refuge 157 

# I 1.4 MODEL RESULTS Model results from the refined analysis are included in Section 6. The tables in Section 6 indicate 

# I 

# I thatthe 98th 

### percentile visibility impairment values are below the 0.5 dv threshold described in CENRAP's BARTModeling Guidelines 

### (December 15,2005). These results indicate that the Horseshoe Lake Station is eligible for a waiver from BART requirements.

### The main components ofthe CALPUFF modeling system are CALMET, CALPUFF, and CALPOST. CALMET is the meteorological model that generates hourly three-dimensional meteorological fields such as wind and temperature. CALPUFF simulates the non-steady state transport, dispersion, and chemical transformation ofair pollutants emitted from a source in "puffs". CALPUFF calculates hourly concentrations ofvisibility affecting pollutants at each specified receptor in a modeling domain. CALPOST is the post-processor for CALPUFF that computes visibility impacts from a source based on the visibility affecting pollutant concentrations that were outputby CALPUFF. 

## 2.1 MODEL VERSIONS 

### Earth Tech, Inc. is the primary developer ofthe CALPUFF modeling system and all related programs. The versions ofthe CALPUFF·modeling system programs that Trinity used for OG&E's modeling are listed in Table 2-1. Table 2-1 also compares the program versions that Trinity used with the program versions recommended by CENRAP. Note that some ofthe program versions are not the same as the program versions recommendedby CENRAP. Certain programs are being utilized in order to avoid data compatibility issues withprevious versions ofthe CALPUFF system. Trinity used the following software version numbers listed below. Model selection was primarily drivenby a desire to utilize the mostrecent release ofCALMET. CALPUFF and CALPOST executable versions were then selected as appropriate for compatibility.

2.2 MODELING DOMAIN 

# I I Trinity utilized a modeling domain that extends at least 50 km in all directions beyond the Horseshoe Lake Station and each its surrounding Class I areas. Note that while UpperBuffalo and HerculesGlades are included in the domain, these Class I 

### areas are more than 300 km from the Horseshoe Lake Station. The map projection for the modeling domain is Lambert Conformal Conic (LCC) and the coordinate system will be North AmericanDatum 1927 (NAD27), which is an LCC projection. 

# I The meteorological grid spacing is 3 km. 

# I The southwest comer ofthe modeling domain is Latitude 34.00oN, Longitude 100.5°W which was assigned as the 0, 0 reference point for the domain. The northeast comer ofthe modeling domain is approximately Latitude 37.25°N, Longitude 92°W. At a grid spacing of3 km, the number ofX grid cells is 256 and the number ofY grid cells will be 155.

# I spacing intervals of3 km were selected to resolve terrain features within the domain. Table 2-2 summarizes the vertical grid structure selected for both analyses. The cell face height ofeach cell indicates its vertical extent. The vertical domain is also composed ofterrain-following grid cells, the number and size ofwhich are chosen so as to constrain the boundary layer in which dispersion and chemical transformations take place.

# I 3. CALMET 

# I Trinity conducted a three-year CALMET analysis incorporating both mesoscale model and observationmeteorological datatogenerate threeyears ofCALMET outputs to be used as inputs to 

# I CALPUFF. The CALMETmodel requires the input ofgeophysical data, meteorological data, and model parameter settings. The CALMET modeling procedures that Trinity is proposingtouse generally follow the recommendations in CENRAP's protocol. It

### should be noted that Trinity used 

# I surface and precipitation databut notupper air observations in this CALMET analysis. As a result, some ofCENRAP'srecommendations may not apply. 

# I 3.1 GEOPHYSICAL DATA 

# I CALMET requires geophysical datato characterize the terrain and land use parameters that potentially affect dispersion. Terrain features affect flows and create turbulence in the atmosphere and are potentially subjected to higher concentrations ofelevated puffs. Different land uses exhibit 

# I variable characteristics such as surface roughness, albedo, Bowen ratio, and leaf-area index that also effectturbulence and dispersion. 

### 3.1.1 TERRAINDATA 

# I Trinity used terrain data obtained from the United States Geological Survey (USGS) in 1­ degree (1 :250,000 scale or approximately 90 meter resolution) digital format. A list ofthe USGS terrain files thatwere used is provided in Appendix

# • I 3.2 METEOROLOGICAL DATA 

# I CALMETwas used to assimilate data for 2001,2002, and 2003 using mesoscale model output and 

# I National Weather Service (NWS) surface station observations, upper air station observations, and precipitation station observations to develop the meteorological field. 

### 3.2.1 MESOSCALEMODELDATA 

# I Hourly mesoscale datawas used to supplement the hourly surface, upper air, and 

# I precipitation observation data. The mesoscale datawas used to define the initial guess field forthe CALMET simulations. Trinity used the following 5th 

### generation mesoscale model meteorological data (orMM5 data):

• 2001 MM5 data (12 

### kIn resolution), 

# I • 2002 MM5 data (36 

### kIn resolution), and • 2003 MM5 data (36

### kIn resolution) 

# I 3.2.2 SURFACE DATA 

### The use ofmUltiple stations for meteorological observations in CALMET/CALPUFF provides a substantial enhancement overthe steady-state treatment ofobservations from a 

# I single meteorological station. Parameters affecting turbulent dispersion that are observed hourly at surface stations include wind speed and direction, temperature, cloud cover and ceiling, relative humidity, and precipitationtype. Surface data were extracted from among 

# I the surface stations listed in AppendixB and are illustrated in Figure 3-3. These sources were selected from the available data inventory to optimize spatial coverage and representation ofthe domain. Raw observations from these stations were obtained from 

# I the National Climatic DataCenter (NCDC), quality assured and were merged usingthe SMERGE pre-processor to create a single assimilated data file ofsurface observations for each year analyzed.

4. CALPUFF 

# I 

# I Trinity conducted a three-year CALPUFF analysis. The CALPUFF model requires the input of meteorological data output by CALMET, source emissions data, receptor data, ozone and ammonia data, and model parameter settings. 

# I 4.1 BART-ELIGIBLE SOURCES 

# I As an electricity generating station, the HorseshoeLake station is considered BART-eligible. In 

# I order to determine what specific units constitute the "BART-eligible" source, the construction dates ofthe each ofthe plant's units mustbe examined. A summary ofthose units that were "in existence" between the IS-yearBART window (August 7, 1962-August 7, 1977) is provided below.

4.4 BACKGROUND OZONE

# I value representative ofan area or hourly ozone datafrom one ormore ozone monitoring stations. CENRAPrecommends either developing background ozone estimates from ambientmonitors located within the particulardomain beingmodeled or developing background ozone estimates from 

# I CENRAP's mostrecent CMAQ or CAMx simulation for the 

### 2002 base year. Trinity used a very conservative value of

### 40 ppb (as recommended in CENRAPprotocol Appendix) in lieu ofthe CENRAPrecommendation. 

# I 4.5 BACKGROUNDAMMONIA 

# I Background ammonia concentrations are required tomodel the formation ofammonium sulfates and ammonium nitrates. CENRAPrecommends developing background ammoniaestimates from CENRAP's mostrecentCMAQorCAMx simulation for the 

### 2002 baseyear. Since 

### CMAQ/CAMx 

# I modeled and observed monthly averaged ammoniaconcentrations exhibit wide spatial variability, CENRAPrecommends obtaining separate monthly-averaged ammonia concentrations from CMAQ orCAMx for the CENRAP north, central and southmodeling domains, respectively. These would 

# I thenbe used as input to CALPUFF, Since the datafrom CENRAP's CMAQ and CAMx simulations is notreadily available, Trinity used a conservative monthly background concentration of

# I Trinity conducted a three-year CALPOST analysis to determine the change in light extinction caused by OG&E's BART-eligible sources when compared to a natural background. The CALPOST model requires the input ofconcentration data outputby CALPUFF

. 

# I 5.1 LIGHT EXTINCTIONALGORITHM 

# I Trinity utilized EPA's currently approved algorithm for reconstructing light extinction (as opposed to the new equation for reconstructing light extinction recommended by the IMPROVE Steering Committee). The light extinction equation is provided below. 

# I = 3*f(RH)*[(NH4)2S04]

# I The algorithm was used to calculate the daily light extinction attributable to the Horseshoe Lake Station's BART-eligible sources and light extinction attributable to a natural background. The 

# I change in deciviews based on the source and background light extinctions was evaluated using the equation below.
