1 Introduction

The technical support tasks in Work Assignment (WA) 5-12 under EPA Contract Number EP-D07-102 are aimed in part at assisting the EPA Region 9 (Pacific Southwest) Air Division in 

developing Federal Implementation Plans (FIPs) to establish air quality programs for Arizona 

pursuant to Clean Air Act (CAA) Section 169A and Regional Haze Rule (RHR) Section 40CFR 

51.308.

The technical analysis for Arizona’s Regional Haze FIP is focused on performing a Best Available Retrofit Technology (BART) analysis and a reasonable progress analysis for potential 

sources. 

The CALMET-CALPUFF-CALPOST modeling system will be used to assess the visibility 

impact of the dispersed pollutant plumes. The purpose of this protocol is to describe the types 

and sources of data to be used in the modeling for this WA, with particular emphasis on the 

sources of emissions data used and the justification for choosing those data sources. In preparing 

this protocol, extensive use has been made of the modeling protocol provided in Appendix A, 

which was followed in previous analyses performed for the Western Regional Partnership 

(WRAP) of BART-eligible sources in Arizona. Exceptions to procedures and recommendations 

made in that protocol are noted as required throughout the main body of this document. Further, 

this protocol reflects our initial approach to modeling, which could be subject to revision as 

regards additional emission scenarios needed, based upon the findings of the initial analyses. 

2 Model Versions

The WA requires the use of the following EPA-approved versions of the modeling components:

(a) CALMET version 5.8, level 070623

(b) CALPUFF version 5.8, level 070623

(c) CALPOST version 6.221

To employ the more recent options to calculate visibility (IMPROVE Method 8) specified in the 

WA, the CALPOST version used is later than that of the dispersion model. Also note that at the 

start of this project the specified CALPOST version was not available for download as it had 

been superseded by a later version, 6.292. However, v6.292 encapsulates and is compatible with 

the features of v6.221, and is the version being used in this WA. 

3 CALPUFF Modeling

All input settings for the CALPUFF modeling follow the values given in the WRAP Protocol for 

BART Exemption Screening (WRAP, 2006) as required by the WA with the exceptions per EPA 

guidance noted in this section. These default input settings are provided in Table 3-3 of WRAP 

(2006).

UNC-EMAQ (5-12)-008.v3 2 July 16, 2012

3.1 Meteorological Data

CALMET is the meteorological model used to provide meteorological inputs for the CALPUFF 

modeling. This WA uses readily available CALMET output provided by the EPA from a

previous modeling effort by ENSR Corporation, the contractor responsible for BART analysis of 

the Salt River Project (SRP)—Navajo Generating Station (NGS) Units 1-3 near Page, AZ 

(ENSR, 2009). Thus the analyses to be performed using this protocol are for the same modeling 

period (2001-2003) and modeling domain that was used in this previous CALPUFF analysis. The 

modeling domain is shown as the area within the blue boundary in Figure 1 (ENSR, 2009); the 

WRAP Arizona BART modeling domain is indicated as the area within the red boundary. For 

reference, the major Class I Areas in Arizona and the six BART sources that are being modeled 

in this WA are also shown in Figure 2. 

The meteorological data for each year of CALPUFF modeling are input hourly, with one input 

file per month modeled, i.e., the value of NMETDAT is non-zero. The options to be selected for 

CALPUFF v5.8 are as follows:

METRUN = 0

IRLG = 24 * NDAYS, where NDAYS is the total number of days of meteorological data 

input

The end date and time for the run should be specified in similar format to the beginning date and 

time.

N.B.: METRUN = 1 will not work in this code version for multiple meteorological input files; 

the beginning date and time, end date and time, and number of hours of meteorological data 

input must be specified.

3.2 Ozone Data

Background ozone levels in parts per billion (ppb) are input to CALPUFF as annual files, and 

have been provided as part of the data downloaded from previous modeling for NGS.

3.3 Ammonia Inputs

Ammonia will be held at a background value of 1 ppb for all months of the model run per EPA 

guidance.

3.4 Modeled and Emitted Species

The choice of modeled and emitted species used for the BART analysis will follow the guidance 

of the WRAP BART modeling protocol (given in Appendix A). Emissions are input for the 

following species: SO2, NOx, and particulate matter (PM); PM is speciated into ammonium 

sulfate, ammonium nitrate, elemental carbon, organic mass, soil, and coarse mass if the types of 

data available allow that speciation. The National Park Service (NPS) provides PM speciation 

profiles in spreadsheets and charts on the following website for speciation of PM emitted by 

several types of combustion units: http://www.nature.nps.gov/air/Permits/ect/index.cfm. If the 

unit being modeled is not identifiable in these spreadsheets, a minimum speciation of PM 

emissions from the facilities into fine and coarse PM (labeled PMF and PMC) will be attempted 

using the AP-42 emission factor data for the type of boiler used in the source modeled. The 

guidance on all the emission inputs to be used for the sources modeled in the WA tasks covered 

by this protocol (Tasks 6, 7, and 8) is provided by EPA in the document given in Appendix B. 

3.5 Discrete Receptor Data

NPS has compiled inputs for CALPUFF modeling of receptors discretized on a 4-km grid for 

each Class I Area and provided the data on their website, along with the software for downloading the data converted from the native latitude-longitude coordinate system to the Lambert 

Conformal Conic grid in which the dispersion modeling tasks for this WA will be performed. 

The discrete receptor data and conversion program are downloadable from www.nature.nps.gov/ 

air/maps/receptors/index.cfm.

4 CALPOST Inputs

Inputs to the CALPOST postprocessor are set according to the guidance of the WRAP BART 

protocol, Section 3.1.3. The following sections provide specifics of how CALPUFF output will 

be processed to calculate the visibility impacts of the selected BART-eligible sources at the 

relevant CIAs for this WA. They include details on the calculation of the natural background 

concentrations of speciated PM for two different definitions of natural conditions, and two 

visibility calculation methods. 

4.1 Postprocessing of CALPUFF Output

Visibility analysis is required for selecting 98th-percentile visibility days, indicated by the 8th-

highest deciview from the annual runs of CALPUFF, as well as the 22nd-highest deciview from 

all three years of model output. CALPOST will be used to calculate the first metric by postprocessing CALPUFF concentration output for each year individually from 2001 through 2003. 

For calculating the second metric, there is no automation available for concatenating the three 

annual ozone files to be used as input to CALPUFF, so a continuous run from 2001 through 2003 

is not possible. Therefore, to select the 22nd-highest deciview day using all three years’ worth of 

output, first the yearly concentration files from CALPUFF should be concatenated using the

APPEND tool distributed with the CALPUFF model, and then CALPOST should be used to 

postprocess the concatenated file to select the 22nd-highest deciview day.

UNC-EMAQ (5-12)-008.v3 6 July 16, 2012

4.2 Natural Visibility Conditions

CALPOST v6.221 includes several methods of calculating natural background visibility. This 

WA requires use of the IMPROVE Method 6, which considers the visibility impacts of PM 

species aggregated over the whole particle size range, and the IMPROVE Method 8 (submode

5), which considers the different visibility impacts of small and large particles, in order to 

compare the results. The input requirements for the two methods are different, and detailed in the 

following sections. 

4.2.1 IMPROVE Method 6

Using Method 6, there are three ways to calculate the natural background visibility based on 

(a) annual average natural conditions, (b) 20% best visibility days, and (c) 20% worst visibility 

days. The WRAP BART analysis for the Western region used all three methods according to the 

WRAP BART protocol. However, the requirements of the WA call for only the first two 

methods, which are described in the following subsections.

4.2.1.1 Annual Average Background Concentrations

To calculate the annual average background extinction, the annual average concentrations for 

SO4, NO3, EC, OC, Soil (labeled PMF in CALPOST), and Coarse Mass (labeled PMC in 

CALPOST) are derived using two types of information from tables given in Guidance for 

Estimating Natural Visibility Conditions under the Regional Haze Rule (EPA, 2003): the dry 

constituent concentrations for the average Western aerosol provided in Table 2-1of this 

document (“Average Natural Levels of Aerosol Components”); and the monthly f(RH) tabulated 

for each CIA, provided in Table A-3, averaged over the year. The annual average f(RH) for each 

CIA is input into the IMPROVE equation along with the dry constituent concentrations:

βext =3 × f(RH) × [Ammonium Sulfate] + 3 × f(RH) × [Ammonium Nitrate] 

+ 0.6 × [Coarse Mass] + 4 × [Organic Carbon] + 1 × [Soil] (1)

+ 10 × [Elemental Carbon] + βray

where 

βext = extinction coefficient (Mm-1)

multiplier preceding f(RH) = extinction efficiency for species named within the brackets

f(RH) = relative humidity adjustment (annual average; unitless)

βray = Rayleigh extinction coefficient (= 10 Mm-1)

[species] = average dry constituent concentration of species named within the brackets for a 

Western aerosol, from EPA (2003), Table 2-1. 

4.2.1.2 Background Concentrations for 20% Best Visibility Days 

To derive the background concentrations of the individual components of PM from the 

extinction coefficient, we would follow the procedure described in the draft CALPUFF BART 

modeling protocol for Montana (MDEQ, 2006; available at

http://www.epa.gov/region8/air/pdf/MontanaBARTProtocol0906.pdf). Values for extinction 
EMAQ LOE (EPA Contract EP-D-07-102) WA 5-12: Task 5 Modeling Protocol for AZ BART Analyses

UNC-EMAQ (5-12)-008.v3 7 July 16, 2012

(Mm-1) for the 20% best visibility days for each CIA are available in Appendix B of EPA (2003), 

following the prescription of Ames and Malm (2002). This approach estimates the 10th-percentile 

haze index (HI) in deciviews (dv), corresponding to the mean of the 20% best visibility values 

(denoted HIb20%), from the annual average haze index, HIann-av, as follows:

HIb20% = HIann-av – 1.28 × sd (2)

where sd, the standard deviation of the HI distribution, has a recommended value of 2 dv for the 

West. From the value of HIb20% derived using Equation (2), the corresponding extinction 

coefficient for the 20% best visibility days, βext-b20%, can be calculated as

βext-b20% = 10 exp (HIb20%/10) (3)

The Montana BART modeling protocol modifies the IMPROVE Equation (1) (Section 4.2.1.1) 

for the 20% best visibility days extinction coefficient by introducing a scaling factor, X, for all 

the PM constituents:

βext-b20% = 3 × f(RH) × [Ammonium Sulfate] × X

+ 3 × f(RH) × [Ammonium Nitrate] × X (4)

+ 0.6 × [Coarse Mass] × X + 4 × [Organic Carbon] × X

+ 1 × [Soil] × X + 10 × [Elemental Carbon] × X + βray

To derive X, βext-b20% can be obtained using Equations 2 and 3, or it can be calculated from the 

HIb20% values tabulated in Appendix B of EPA (2003) for each CIA. The value for X can then be 

determined from Equation 4 and applied to each of the PM constituent annual average background concentrations at each CIA to obtain the corresponding background concentrations on the 

20% best visibility days. The average Western aerosol constituent background concentrations 

needed to estimate the reference extinction (Mm-1) are provided in Table 1 below for the CIAs of 

interest for the Arizona sources being modeled in this WA, along with the extinction efficiency 

by constituent taken from EPA (2003). For each Arizona CIA affected by the BART-eligible 

sources in Arizona, Table 2 gives its annual f(RH) and its extinction coefficients for reference 

conditions and for 20% best visibility conditions as calculated using Equations 2 and 3 above. 

Table 3 shows the background PM concentrations calculated using the Table 2 values of βext-b20%

for the same CIAs. A complete list of the 156 CIAs in North America along with their 

background extinctions and concentrations for the 20% best visibility days calculated using the 

above method is provided in Appendix C of this protocol for reference.

4.2.2 IMPROVE Method 8

Under IMPROVE Method 8 (submode 5), the extinction coefficient, βext, is calculated as 

follows:

βext = 2.2 × fS(RH) × [Small Sulfate] + 4.8 × fL(RH) × [Large Sulfate] 

+ 2.4 × fS(RH) × [Small Nitrate] + 5.1 × fL(RH) × [Large Nitrate] 

+ 2.8 × [Small Organic Mass] + 6.1 × [Large Organic Mass] 

+ 10 × [Elemental Carbon] + 1 × [Fine Soil] + 0.6 × [Coarse Mass] 

+ 1.7 × fSS(RH) × [Sea Salt] + βRay (site specific) 

+ 0.33 × [NO2 (ppb)] {or as: 0.1755 × [NO2 (μg/m3)]}

where the subscripts S, L, and SS represent small particles, large particles, and sea salt,

respectively, and a site-specific value of βRay replaces the constant value of 10 Mm-1in Eq. 1.

All inputs needed for calculating βext for each CIA using the method above are provided in the 

FLAG-2010 report (FLM, 2010) and are given in Appendix D of this protocol. Figure 5 of that

report provides the relationship to be used between total background concentrations of sulfate,

nitrate, and organic mass and their corresponding concentrations in the small and large size 

fractions to calculate the size-specific inputs for these species in CALPOST. Total PM 

constituent concentrations and Rayleigh scattering coefficients for the 20% best visibility days 

and annual average natural conditions for each CIA are provided in FLM (2010) Tables 5 and 6,

respectively, while the monthly f(RH) adjustment factors for large- and small-mode sulfate, 

nitrate, and sea salt can be found in Tables 7 through 9 of that report. These inputs are used in 

CALPOST to calculate the extinction coefficient, βext.

1 BART Sources and Their Emissions Inputs

There are a total of 3 facilities that will be analyzed through CALPUFF visibility modeling as 

part of the Tasks 8 WA as follows:

Task 8: Perform a full five-factor BART analysis for NOx controls with emissions inputs as 

follows:

(a) Apache Generating Station (AEPCO), Units 1-3 (controls evaluated for 2 & 3): All units 

will use ADEQ BART limits on emission factors for SO2 and PM, multiplied by the maximum 

daily-average heat inputs (BTU/hr) from CAMD/CEMS (2008-2010) to calculate the respective 

emission rates for these pollutants. Unit 1 (not eligible for BART) will use the ADEQ BART 

limits also on NOx, multiplied by the maximum daily-average heat input (BTU/hr) from 

CAMD/CEMS (2008-2010) to calculate the NOx emission rate. PM Speciation for this unit 

should use NPS spreadsheet data for “Gas-Fired Combustion Turbine Example” (see 

http://www.nature.nps.gov/air/Permits/ect/docs/gasCT/EdRevConsensusGasCTexample.xls). For 

Units 2 and 3, the NOx baseline values will be taken as the CAMD/CEMS (2008-2010) 

maximum daily-average NOx emission rates. The stack parameters provided by the facility 

(Table B-2) should be used in place of the WRAP stack parameters, due to erroneous WRAP 

modeling inputs for exit velocity and exit temperature. PM speciation should use the NPS 

spreadsheet data for “PC Dry Bottom FGD and ESP Example” (see 

http://www.nature.nps.gov/air/Permits/ect/docs/coalBoiler/2006FinalDryBottomPC_FGD_ESPp

mSpeciationProfile.xls). Heating value, and percent coal ash and sulfur content needed as inputs 

to the spreadsheet are provided in Table B-1.

(b) Cholla Power Plant, Units 1-4: Unit 1 is not BART-eligible, and will use actual maximum 

daily average emissions from CAMD/CEMS (2008-2010) for SO2 and NOx for all runs. For PM, 

this unit has a baghouse similar to the BART-eligible units 2-4, and thus the ADEQ BART limit 

of 0.015 lb/mmBTU should be used for the PM emission factor; this should be multiplied by the 

maximum daily-average heat input (BTU/hr) from CAMD/CEMS (2008-2010) to calculate the 

filterable PM emission rate. Speciation of PM emissions should be done using the NPS 

spreadsheets for “PC Dry Bottom FF and FGD Example” (see 

http://www.nature.nps.gov/air/Permits/ect/docs/coalBoiler/2006FinalDryBottomPC_FGD_FFpm

SpeciationProfile.xls). For Units 2-4, the NOx baseline values will be the actual CAMD/CEMS 

(2008-2010) maximum daily-average NOx emission rates; SO2 and PM emissions should be 

based on ADEQ BART limits on emission factors multiplied by the maximum daily-average 

heat inputs (BTU/hr) from CAMD/CEMS (2008-2010). Speciation of PM for Units 2 and 3 

should be as in Unit 1, but for Unit 4 it should use NPS spreadsheet data for “PC Dry Bottom 

Wet Scrubber Example” (see 

http://www.nature.nps.gov/air/Permits/ect/docs/coalBoiler/2006FinalDryBottomPCScrubberPmS

peciationProfile.xls). Heating value, and percent coal ash and sulfur content needed as inputs to 

the spreadsheets are provided in Table B-1. Updated stack parameters provided by the facility 

(Table B-2) should be used.

(c) SRP Coronado Units 1 and 2 (controls evaluated for 1): 2008 will be the highest emission 

year for this plant. ENSR/AECOM, the contractor who previously performed the BART analysis 

on this plant, also had different stack parameters before and after NOx burner installation. The 
EMAQ LOE (EPA Contract EP-D-07-102) WA 5-12: Task 5 Modeling Protocol for AZ BART Analyses

UNC-EMAQ (5-12)-008.v3 July 16, 2012

parameters appropriate to the plant conditions in 2008 should be used. Unit 1 will use ADEQ 

BART limits on emission factors for SO2 and PM, multiplied by the maximum daily-average 

heat input (BTU/hr) from CAMD/CEMS (2008-2010) to calculate the respective emission rates 

for these pollutants. For Unit 1, the NOx baseline value will be the CAMD/CEMS 2008

maximum daily-average NOx emission rate. Unit 2 is also eligible for BART, but a Consent 

Decree (CD) applies to it, thus the emissions will held at the following values: 0.08 lb/mmBTU 

for SO2 and NOx, and 0.03 lb/mmBTU for filterable PM, multiplied by the maximum dailyaverage heat input (BTU/hr) from CAMD/CEMS 2008 to calculate the respective emission rates. 

ENSR calculated PM speciation for this plant, and these data should be used to speciate the PM 

emissions above.
