I 	 1.0 INTRODUCTION 

Terra International (Oklahoma), Inc. (Terra) operates a nitric acid, ammonia, urea I ammonium nitrate (UAN), and. methanol production facility (Facility) located in 

Woodward, Oklahoma. The Facility is currently authorized to operate under Permit No. I 98-299-TV (Permit), which was issued by the Oklahoma Department of Environmental 

Quality (ODEQ) on February 26, 2002. I 

The United States Environmental Protection Agency (EPA) issued the Regional Haze I 	 Regulations initially in 1999 to improve visual air quality in national parks and 

wilderness areas (Class I areas) across the country. The regulation sp~cifically 

I 

·1 requires states to establish goals for improving visibility in Class I areas and to develop 

long-term strategies for reducing emissions of certain air pollutants. The EPA 

I 

published final amendments to the 1999 Regional Haze Rule on July 6, 2005 which 

includes final guidance for Best Available Retrofit Technology (BART) determinations in 

I 

Appendix Y of the Federal Register (70 FR 39104-39172). Under the Regional Haze 

Rule, states have the authority to exempt cert~in BART-eligible sources based on 

I 

dispersion modeling demonstrating that the source cannot reasonably be anticipated to 

cause or contribute to visibility impairment in a Class I area. 

I Oklahoma Administrative Code (OAO) 252:100-8, Part 11 addresses BART eligible 

I 

sources that may reasonably be anticipated to cause or contribute to visibility 

impairment in any mandatory federal Class I area. The Air Quality Council (AQC) 

I 

approved OAC 252:100-8, Part 11 for permanent rulemaking on April 19, 2006. The 

Environmental Quality Board (EQB) approved Part 11 as both a permanent and 

emergency rule on August 22, 2006. The rule was signed by the Governor as

emergency on October 8, 2006. Part 11 of OAC 252:100-8 is expected to become I permanently effective on June 15, 2007. 

I 

I 

I Terra is submitting this Class I Area Visibility Modeling Analysis and BART Waiver 

Application (Application) to request and obtain a waiver from the ODEQ in accordance I with OAC 252:100-8-73(c)(3), which states a BART determination is not required "if the 

owner operator of the BART-eligible source demonstrates by modeling, in accordance 

with a protocol approved by the Director, that a source does not emit any air pollutant 

which may reasonably be anticipated to cause or contribute to visibility impairment in 

I 

any Class I Federal area." In addition, OAC 252:100-75(c), requires that any BART 

waiver applications be submitted by December 1, 2006. 

I At the request of Terra, The Benham Companies, LLC (Benham), has performed an 

I 


Class I Area visibility modeling analysis to document that the source does not emit any 


air pollutant which may reasonable be anticipated to cause or contribute to visibility 


I 


impairment in any mandatory Class I Federal area. This modeling analysis was 


performed based on guidance found in the Central Regional Air Planning Association 


I 


(CENRAP) BART Modeling Guidelines (December 2005) (CENRAP Guidance) and 


from guidance obtained from the ODEQ.

OAC 252:100-8-71 includes definitions used to identify a BART-eligible source. In 

addition, OAC 252:100-8-72 incorporates Appendix Y of 40 CFR 51, Guidelines for I BART Determinations under the Regional Haze Rule, by reference. The ODEQ defines 

sources that are potentially BART-eligible as existing stationary sources of air pollutants 

from one of 26 identified source categories, including any reconstructed source, which 

was not in operation prior to August 7, 1962, and was in existence on August 7, 1977, 

I 

and has the potential to emit (PTE) 250 tons per year (T/yr) or more of any air visibilityimpairing pollutants.

I 

The BART guidelines under Appendix Y of 40 CFR 51 include a step-by-step analysis 

for determining if a source may be considered to be BART-eligible. The four steps are 

as follows: 

I 

I 

> Step 1: 

> Step 2: 

> Step 3: 

I 

Identify the emission units in the BART categories 

Identify the start-updates of those emission units 

Compare the potential emissions from the units identified in steps 1 

and 2 to the 250 T/yr threshold 

> Step 4: Identify the emission units and pollutants that constitute the BARTI eligible source 

I A brief summary of each of these steps is provided in Sections 2.3.1 through 2.3.4. A 

summary of the BART-eligible sources at the Facility is included in Table 2-1. 

I 

2.3.1 Step 1 : Identify Emission Units in the BART Categories 

I The BART categories include major stationary sources as identified on the list of 26 

source categories as included in OAC 252:100-8-71. The Standard Industrial 

I Classification (SIC) Code for the Facility is 2873. The Facility is included on the list 

under three specific source categories: "nitric acid plants", "chemical process plants", 

I and "fossil-fuel boilers of more than 250 million British Thermal Units per hour 

(MMBtu/hr) heat input." 

I 

2.3.2 Step 2: Identify the Start-up Dates of the Emission Units I Emission units identified in Step 1 are BART-eligible if they were "in existence" on 

August 7, 1977 but we~e not "in operation" before August 7, 1962. Under OAC I 252:100-8-71, the term "in existence" is identified as meaning "that.the owner or 

operator has obtained all necessary preconstruction approvals or permits required by I the Department and EPA and either has: (A) begun, or caused to begin, a continuous 

program of physical construction of the facility; or (B) entered into binding agreements I

I or contractual obligations which cannot be cancelled or modified without substantial 

I 

loss to the owner or operator to undertake a program of construction of the facility to be 

completed in a reasonable time." The term "in operation" is defined as "engaged in 

activity related to the primary design function of the source." 

I 

I 

The BART guidelines require facilities to also take into consideration so~rces which 

were in operation before August 7, 1962 and were "reconstructed" during the August 7, 

I 

1962 to August 7, 1977 timeframe. A source is considered reconstructed "if the fixed 

capital cost of the new component exceeds 50 percent of the fixed capital cost of a 

I 

comparable entirely new source." The current BART regulations do not provide 

exemptions for sources that were "modified" after August 7, 1977. 

I Terra operates units that were "in existence" prior to August 7, 1977 and were not "in 

operation" prior to August 7, 1962. In addition, the units identified have not been 

I "reconstructed" after August 7, 1977. 

I 2.3.3 Step 3: Compare the Potential Emissions to the 250 T/yr Cutoff 

The purpose of this step is to determine whether the total emissions represent a current 

I PTE that is greater than 250 T/yr of any single visibility-impairing pollutant. The BART 

guidelines address emissions of sulfur dioxides (S02). nitrogen oxides (NOx), and 

I particulate matter (pM) as visibility-impairing pollutants. PM with an aerodynamic 

diameter less than 10 microns (PM10) is used as an indicator in this step. States have 

I the option to also include volatile organic compounds (VOC) and ammonia as visibilityimpairing pollutants. The Facility has the potential to emit VOC and ammonia; however, 

I ammonia and VOC emissions were not included in accordance with OAC 252:100-8-73. 

I As presented in Table 2-1, the PTE for NOx from the sources identified is greater than 

250 T/yr. I

2.3.4 Step 4: Identify the Emissions Units and Pollutants That Constitute the 

I 

I BART-eligible Source 

A source is considered BART-eligible if the emissions from the list of emissions units at 

I 

a stationary source exceed a PTE of 250 T/yr for any visibility-impairing pollutant. The 

guidelines indicate that if a source has a PTE greater than 250 T/yr for one visibilityI 

impairing pollutant (i.e. NOx), then the source is subject to a BART review for all 

visibility-impairing pollutants (Le. NOx, S02, and PM). 

I 2.4 Affected Class I Areas 

I 

A Class I area is an area of the country with special national or regional value from a 

natural, scenic, recreational, or historic perspective. These Class I areas are afforded 

special protection to minimize the impacts of sources on their air quality. In accordance 

I with the CENRAP modeling guidance, all Class I areas located within a 300 kilometer 

(km) radius of the Facility are required to be evaluated for visibility. 

I 

This modeling analysis evaluated visibility impacts at the Wichita Mountains National 

I Wildlife Refuge (WMNWR), located approximately 194 km or approximately 120 miles 

to the southeast of the Facility. There are no other Class I areas located within a 300 

I km radius of the Facility. 

I 	 A map of the Facility's location in relation to each Class I area located within a 300 km 

from the Facility's center is provided in Figure 2-2.

November 2006 


I 3.0 AIR QUALITY MODEL AND MODELING INPUT DATA 

3.1 Model Selection 

I According to the Regional Haze Rule's BART modeling guidance, a source can use the 

I 

California Puff (CALPUFF) model to predict the visibility impacts from a single source at 

a Class I area. 

I Benham used the CALPUFF screening approach consistent with the procedures 

outlined in the CENRAP Guidance.. The CALPUFF screening methodology uses a 

I standard set of default meteorological, air quality, and dispersion conditions that are 

consistent with the Interagency Workgroup on Air Quality Modeling (lWAQM), Phase 2 

I recommendations for long-range transport guidance (December 1998) and Federal 

Land Managers' Air Quality Related Values Workgroup (FLAG) Phase 1 

I recommendations (December 2000). The CALPUFF screening approach provides a 

conservative analysis to predict the source's visibility impact at a Class I area. 

I 

Based on guidance obtained from ODEQ, the version of the CALPUFF model used in 

I this analysis is the CALPUFF VISTAS Recommended Version for BART Modeling 

(VISTAS Version 5). Benham utilized the BEEST Professional CALPUFF Version 2.33 

I (BEEST Pro' CALPUFF) program, which has incorporated the CALPUFF VISTAS 

Version 5 modeling system. In addition, the BEEST Pro CALPUFF program includes a I 	 CENRAP screening feature that has incorporated the. CALPUFF screening 

recommendations and defaults. I 

There are three (3) main components of the CALPUFF modeling system: I ~ Meteorological Data Modeling (CALMET); I ~ Dispersion Modeling (CALPUFF); and, 


I 
 ~ Post Processing (CALPOST).

,I The remainder of this section provides a description of the modeling inputs and general 

modeling approach. 

I 3.2 Domain Configurations and Receptors 

I 

I For the CALPUFF screening approach,. model-ready meteorological data sets have 

been developed by CENRAP for three (3) CENRAP sub-regional domains. The data 

sets cover three (3) contiguous years (2001, 2002, and 2003) and are resolved to a six 

I 

(6) km horizontal resolution grid. Due to the location of the Facility and the location of 

the Class I area in consideration, the CALPUFF screening modeling for the Facility was 

I 

conducted using the CENRAP south six (6) km grid for years 2001, 2002, and 2003. 

The extent of the CENRAP south sub-regional domain is shown in Figure 3-1. 

I Based on CENRAP guidance, the computational domain used in the modeling analysis 

I 

includes all Class I areas located within 300 km from the Facility, As described 

previously in Section 2.4, the WMNWR is located approximately 194 km from the 

Facility. The computational domain was determined based on the distance from the 

I Facility to the nearest receptor in the Class I area. A buffer of 50 km in each cardinal 

direction was then added to the modeling domain. There are no other Class I areas 

I located within 300 km of the Facility. The extent of the computational domain is shown 

in Figure 3-2. 

I 

Receptors are locations where model results are calculated and provided in the 

I CALPUFF output files. Receptor locations and elevations were derived from the 

National Park Service (NPS) Class I area receptor database. The discrete receptors 

'I were necessary for calculating visibility impacts in WMNWR.

I 3.3 Source Parameters and Emissions Input 

I 

I 

3.3.1 Stack Parameters 

The stack parameters required for modeling the BART-eligible units at the Facility are 

I 

stack height from ground, stack diameter, exit gas flow rate, exit gas temperature, base 

elevation above sea level, and location coordinates of the stack. A summary of the 

modeled stack parameters is included in Table 3-1. 

I 

I 

3.3.2 Modeled Emission Rates 

According to the BART guidance, emission rates applied in the BART analysis should 

be based on the 24-hour average actual emission rate from normal operations from the 
 I, highest emitting day of the year. The highest emitting day of the year is determined 


based on data from a 3-5 year period. In addition, days where startup, shutdown, or 


I malfunctions occurred should be excluded unless these activities are regular, frequent 


occurrences. Based on the guidelines, identification of the maximum 24-hour actual 


I emission rates should be made for the most recent years according to the following 


prioritization:


I' 


);> Continuous Emissions Monitoring (CEM) data; 

I );> Facility emissions tests; 

);> Emissions factors; 

I );> Permit limits; or lastly, 

);> Potential to emit. 

I 

The species that should be modeled in the screening analysis include S02. NOx and 

I PM1o. According to OAC 252:100-B-73(c)(1) and (2), if a source has the potential to 

'emit less than de minimis quantities (i.e. 40 T/yr of S02 and NOx or less than 15 T/yr of 

I PM1Q) a BART determination is not required.

I To be conservative. the permitted emission rates for each source were input into the 

I 

model instead of actual emission rates. The permitted facility-wide S02 emission rates 

are below the de minimis level (Le. less than 40 T/yr) and are not subject to BART 

I 

review; therefore, S02 emissions from the BART-eligible sources at the Facility were 

excluded from the modeling analysis. 

I The plant flares were modeled assuming continuous operation of the flare pilot gas.

Emissions resulting from start-ups, shutdowns, or upsets from the flares were excluded 

from the model based on the CENRAP modeling guidelines. 

I 3.3.3 Speciation and PM Size Distribution 

I 

Particle size parameters were used in the CALPUFF input file for dry deposition of 

particles. There are default values for "aerosol" species (Le., sulfate (S04), nitrate 

(N03). and PM2.5). The default value for each of these species is 0.48 micrometer (IJm) 

I geometric mass mean diameter and 2.0 IJm geometric standard deviation. 

I The PM emissions from each source are required to be separated by size category, if 

such data is known or available. The size categories employed in this modeling 

I analysis consisted of coarse PM (PMC) and fine PM (PMF). PMC includes particles 

with an aerodynamic diameter between 10 to 2.5 micrometers and PMF includes 

particles with an aerodynamic diameter less than 2.5 micrometers. I , 

I The majority of the BART-eligible sources at the Facility are natural gas-fired 

combustion units. AP-42 Section 1.4 indicates that all PM is assumed to be less than 

I 1.0 micrometer in diameter. Therefore, all PM from the natural gas fired sources was 

assigned to the PMF category or was assumed to be PM2.5. 

I 

For the ammonium nitrate neutralizer, PM emissions were categorized based on 

I information found in EPA's PM calculator program. PM calculator estimates that 83% 

of the total PM from the neutralizer is less than 2.5 micrometers. Therefore, 83% of the I

total PM emissions were assigned to the PMF category (i.e. PM2.5) and the remainder I (i.e. 17%) was assigned to the PMC category (i.e. PM10). 

I A summary of the modeled emission rates are provided in Table 3-2. 

I 3.3.4 Building Downwash Analysis 

I The modeling conducted for BART applications ,is focused on long range transport 

I 

instead of localized impacts. Including the effects of downwash in the BART screening 

analysis is not necessary due to the distance' from the Facility in relation to the 

I 

WMNWR. However, the CENRAP guidance suggests that building downwash should 

be included for each BART screening application without taking into consideration the 

distance of the Facility from the Class I areas. 

I 

The Building Profile Input Program Prime (BPIP-Prime, Version 95086) was used to 

I determine directionally-dependent aerodynamic do~nwash structure dimensions (Le. 

heights and projected widths) for each emission point modeled, as a function of the 

I layout of the structures' and emission points. The automated algorithm used for this 

analysis was the BEE BPIP-Prime software. The BPIP-Prime algorithm generates 

I directionally-dependent vertical and horizontal structure dimensions for each emission 

point, for each 10-degree directional segment. The structure dimensions are then 

I imported into the CALPUFF model on an emission point-specific basis. 

I 3.3.5 Meteorological Data Modeling (CALMET) 

As previously indicated, the 2001-2003 CENRAP-developed CALMET dataset was 

I applied in the BART screening analysis. Since no observational data were used in the 

CALMET outputs developed by CENRAP, the prognostic meteorological dataset from 

I MM5 was not supplemented with surface or upper air observations during the CALMET 

processing. The use of observations is thought to counterbalance smoothing that may I occur when using the coarse grid scale of the MM5 data. Thus, CENRAP considers

I this screening modeling to be conservative and does not require the use of 

observational data. 

I 

I 

Modeling was performed for each of the annual datasets. For year 2003, only 8,736 

hours (Le. 364 days) were input into the model since the dataset only includes 12 hours 

on December 31,2003. A total of 8,760 hours was modeled for years 2001 arid 2002. 

I 

I 

3.4 Dispersion Modeling (CALPUFF) 

The CALMET output is used as input into the CALPUFF model. The CALPUFF model 

I 

simulates the effects of the meteorological conditions in the transport and dispersion of 

pollutants from an individual source. The CENRAP provided default options were used 

I 

in the CALPUFF model. The CALPUFF model also has a puff-splitting option that splits 

puffs that become large over greater transport distances. Based on CENRAP 

guidance, the puff-splitting option was not u'sed in the screening analysis. 

I 

Appendix A includes a summary of the CALPUFF settings used in the screening 

I analysis. 

I 3.4.1 Ozone and Ammonia Concentrations 

Ozone (03) and ammonia (NH3) were input into CALPUFF as monthly background 

I values. Background ozone and ammonia concentrations are assumed to be temporally 

and spatially invariant and were fixed at 40 and 3 parts per billion (ppb), respectively, 

I across the entire domain for each month (January thru December). The values used 

for background ozone and ammonia concentrations in CALPUFF are consistent with 

I CENRAP guidelines. 

I 3.4.2 CALPUFF Outputs 

The CALPUFF modeling results are displayed in units of micrograms per cubic meter 

I (l.Jg/m\ To determine visibility impacts from the Facility on the WMNWR, the

Terra International (Oklahoma), Inc. 

I Woodward Plant 

November 2006 

I CALPUFF model results must be post processed using the POSTWTIL and CALPOST 

features. 

I 3.5 Post Processing (CALPOST) 

I Post processing involves processing the CALPUFF model results with the POSTUTIL 

I 

and CALPOST to determine visibility conditions. POSTUTIL takes the concentration 

file output from CALPUFF and recalculates the nitric acid and nitrate partition based on 

I 

total available sulfate and ammonia. CALPOST uses the concentration file processed 

through POSTUTIL, along with relative humidity data, to perform visibility calculations. 

I A summary of the detailed settings used for POSTUTIL are provided in Appendix B. 

I 

The ammonia limiting method (ALM) in CALPUFF repartitions the nitric acid and nitrate 

on a receptor-by-receptor and hour-by-hour basis to account for the CALPUFF model's 

over prediction due to overlapping puffs. The CENRAP guidance suggests that this 

I correction should be used by setting MNITRATE = 1 in POSTUTIL to perform 

repartitioning of nitric acid and ammonia. For this screening application, repartitioning 

I of nitric acid and ammonia was not performed, which results' in a more conservative 

approach for determining visibility impacts. 

I 

A summary of the detailed settings used for CALPOST are provided in Appendix C with 

I additional details for specific parameters provided in the following sections. 

I 3.5.1 Light Extinction Coefficient 

Perceived visibility in deciviews (dv) is derived from the light extinction coefficient. The 

I CALPOST program has several methods for computing light extinction. CENRAP 

guidance re.commends that Method 6 be used to estimate light extinction. Method 6 

I computes light extinction from speciated particulate matter with monthly Class I areaspecific relative humidity adjustment factors. Relative humidity is a factor in calculating I light extinction since sulfate and nitrate aerosols, which absorb. moisture from the air, 

have greater extinction efficiencies with greater relative humidity.

I 

The relative humidity correction factors (f(RH)) for the WMNWR was obtained from 

EPA's "Guidance for Estimating Natural Visibility Conditions under the Regional Haze 

I 

Rule" dated September 2003. The values are provided in Table A-3 of the EPA 

"Guidance for Estimating Natural Visibility Conditions Under the Regional Haze Rule" 

I 

dated September 2003. For reference, a copy of the f(RH) values from the 2003 EPA 

document are provided in Appendix D. 

I 3.5.2 Visibility Impacts 

I 

The visibility change related to background is calculated using' the modeled and 

established natural visibility conditions. For the BART screening analysis, daily visibility 

is expressed as a change in dv (delta dv) compared to natural visibility conditions. 

I 

The natural conditions for a Class I area is based on whether the Class I area is located 

I in the eastern or western part of the United States. The data is provided in EPA's 

"Guidance for Estimating Natural Visibility Conditions under the Regional Haze Rule" 

I dated September 2003. The WMNWR is located in the eastern part of the United 

States. The annual average natural levels of aerosol components at the WMNWR are 

I summarized in Appendix C. 

I The EPA BART guidelines allow the use of the 98th percentile impact for determining if 

a source has the potential to cause or contribute to regional haze in a Class I area. The 

I 98th CENRAP guidance deviates from the use of the percentile. As discussed 

previously, the model ready CALMET datasets were processed without using the 

I surface and upper air meteorological observations (Le. "No-Obs") in the wind field 

interpolation. Since the use of "No-Obs" may lead to less conservative calculations as 

I compared to the use of CALMET with observations, EPA has recommended to 

CENRAP that the maximum visibility impact be used for the CALPUFF screening I analysis. Therefore, the maximum impact was used for determining if the Facility has 

the potential to cause or contribute to visibility impairment in the Class I area. I

I 4.0 MODELING RESULTS 

I 

The CALPOST processor computes the daily (24-hour) maximum change in (delta) 

deciviews at the Class I area from the modeled sources. A summary of the daily 

maximum delta deciview for each year is provided in Table 4-1. 

I 

A summary of the modeling results is as follows: 

I 

I 

> Number of receptors within each Class I area with impacts> 0.5 dv = 0 

> Number of days at all, receptors within each Class I area with impacts> 0.5 dv = 0 

> Largest delta deciview =0.405 

I 

As indicated in the results provided in Table 4-1, the daily maximum change in 

I deciviews is below the threshold of 0.5; therefore,the Facility is not expected to cause 

or contribute to visibility impairment in the WMNWR. In addition, the CALPUFF 

I screening modeling approach recommended by CENRAP and utilized for this 

application includes a high degree of conservatism compared with the refined 

I CALPUFF methodology. 

I In accordance with OAC. 252:100-B-73(c), Terra is eligible to obtain a waiver for the 

Facility from ODEQ that a BART determination is not required and further refined I modeling is not warranted. 

I Electronic copies of the modeling files on DVD-ROM are provided in Appendix E.
