shall be performed in accordance with the following:
A. Sample Location: The emission point shall be designed to conform to the requirements
of 40 CFR 60, Appendix A, Method 1, or other EPA-approved testing methods
acceptable to the Director. Occupational Safety and Health Administration (OSHA) approvable access shall be provided to the test location
B. Volumetric Flow Rate: 40 CFR 60, Appendix A, Method 2, or other EPA-approved testing methods acceptable to the Director
C. NOx: 40 CFR 60 Appendix A, Method 7E, or other EPA-approved testing methods acceptable to the Director
D. CO: 40 CFR 60 Appendix A, Method 10, 10B, or other EPA-approved testing methods acceptable to the Director
E. Calculations: To determine mass emission rates (lb/hr, etc.), the pollutant concentration as determined by the appropriate methods above shall be multiplied by the volumetric
flow rate and any necessary conversion factors to give the results in the specified units of
the emission limitation. A stack test protocol shall be provided at least 30 days prior to the test. A pretest conference shall be held if directed by the Director
F. The production rate during all compliance testing shall be no less than 90% of the maximum production rate achieved in the previous three (3) years. If the desired
production rate is not achieved at the time of the test, the maximum production rate shall
be 110% of the tested achieved rate, but not more than the maximum allowable production rate. This new allowable maximum production rate shall remain in effect
until successfully tested at a higher rate. The owner/operator shall request a higher
production rate when necessary. Testing at no less than 90% of the higher rate shall be
conducted. A new maximum production rate (110% of the new rate) will then be allowed
if the test is successful. This process may be repeated until the maximum allowable
production rate is achieved
G. Stack testing on each internal combustion engine shall be performed once every 8,760
hours of operation of that engine, but no less frequently than once every three (3) years,
whichever condition is met first.

SUBJECT: Modeling Analysis Review for the Notice of Intent for Springville City Corporation –
Whitehead Power Plant, Utah County, Utah
_____________________________________________________________________________________
This is not a Major Prevention of Significant Deterioration (PSD) Source.
I. OBJECTIVE
Springville City Corporation (Applicant) is seeking an approval order for their Whitehead Power
Plant located in Utah County, Utah.
This report, prepared by the Staff of the New Source Review Section (NSR), contains a review of
the air quality impact analysis (AQIA) including the information, data, assumptions and modeling
results used to determine if the facility will be in compliance with applicable State and Federal
concentration standards.
II. APPLICABLE RULE(S)
Utah Air Quality Rules:
R307-401-6 Condition for Issuing an Approval Order
R307-410-3 Use of Dispersion Models
R307-410-4 Modeling of Criteria Pollutants in Attainment Areas
III. MODELING METHODOLOGY
A. Applicability
Emissions from the facility include PM10, NOx, CO, SO2, and HAPs. This modeling is part of a modified approval order. The emission rates for NOx triggered the requirement to model under
R307-410. Modeling was performed by the Applicant.

B. Assumptions
1. Topography/Terrain
The Plant is at an elevation 4530 feet with terrain features that have an affect on
concentration predictions.
a. Zone: 12
b. Approximate Location:
UTM (NAD83): 447,400 meters East
4,447,250 meters North
2. Urban or Rural Area Designation
After a review of the appropriate 7.5 minute quadrangles, it was concluded the area is “rural” for air modeling purposes.
3. Ambient Air
It was determined the Plant boundary used in the AQIA meets the State’s definition of
ambient air.
4. Building Downwash
The source was modeled with the AERMOD model. All structures at the plant were used in
the model to account for their influence on downwash.
5. Meteorology
Five (5) years of off-site surface and upper air data were used in the analysis consisting of
the following:
Surface – Salt Lake Airport, UT NWS: 2016-2020
Upper Air – Salt Lake Airport, UT NWS: 2016-2020
6. Background
The background concentrations were based on concentrations measured in Spanish Fork,
Utah.
7. Receptor and Terrain Elevations
The modeling domain used by the Applicant consisted of receptors including property
boundary receptors. This area of the state contains mountainous terrain and the modeling
domain has simple and complex terrain features in the near and far fields. Therefore,
receptor points representing actual terrain elevations from the area were used in the
analysis.
DAQE- MN108190010-24

8. Model and Options
The State-accepted AERMOD model was used to predict air pollutant concentrations under
a simple/complex terrain/wake effect situation. In quantifying concentrations, the
regulatory default option was selected.

Reference: Updated Dispersion Modeling for AO Modification – Springville Power Corporation
Mr. Humphreys:
Stantec Consulting Services, Inc. (Stantec) is submitting a proposed modification/revision to the current Approval Order (AO) , DAQE-AN108190009-24, issued May 8th, 2024, on behalf of Springville Power Corporation (Springville). The current AO includes permit condition II.B.2.e, which limits the start-up hours for the Caterpillar engines from 8:00-11:00 AM daily. This condition was included because of the initial 1-hr NO2 dispersion modeling incorporated that restricted. However, Stantec has reassessed and conducted new modeling in support of removal the condition. All permitted emissions are unchanged.
The updated modeling is consistent with the analysis conducted for the current AO in terms of stack parameters, background values and meteorological data. The only modification was to eliminate the start-up time hours. Rather, the new analysis assumes that start-up could occur at any time throughout the year. Thus, the start-up emission rate is applied continuously.
Stantec and Springville are also providing a new Form 2 with signature. No other information is included in this submittal. Should UDAQ require anything further, please let us know. Any associated fees will be paid upon receipt of an invoice from UDAQ.

1.0 PURPOSE
This air quality modeling report documents a minor change to the previous to the current
Approval Order, DAQE-AN108190009-24, issued May 8th, 2024. The current Approval Order allows
the Springville Power Corporation (Springville) facility to comprise two Enterprise natural
gas/diesel engines (K1&K2), five Caterpillar G3520H engines (K3-K7) and a 6 MMBtu/hr natural
gas boiler. There are no emissions or physical changes to the August 2023 modeling files. The
only modifications are the elimination of the start-up timing restriction. This updated modeling
report demonstrates compliance with the 1-hr NO2 National Ambient Air Quality Standard with
the removal of permit condition II.B.2.e.
All pertinent, updated modeling-related files are provided in electronic format. This includes
AERMAP terrain information, BPIP downwash files, NED data and meteorological/background
data.
1.1 PROCESS DESCRIPTION
Springville Power currently consists of two nameplate 7.0 megawatt (MW) Enterprise engines (will
not exceed 5.5 MW when operating); five 2,403 kW 4-stroke lean burn natural gas engines and
one 6.0 MMBtu/hr boiler. Each of the Caterpillar engines will be equipped with an oxidation
catalyst and selective catalytic reduction (SCR). The 6.0 MMBtu/hr boiler remains unchanged.
A nearby facility, Pacific pipeline, was included in the modeling analysis at the request of the
Utah Division of Air Quality (UDAQ). This was included from 2017 UDAQ modeling conducted at
the facility and has been applied without modification. Lastly, Springville owns the property to
the south of 700 North. The property boundary has been adjusted to the incorporate those
parcels. In accordance with the Utah County assessor, three parcels are owned by Springville
that comprise approximately 13.23 acres. These parcels are now excluded from ambient air (700
North remains part of ambient air). This is consistent with the 2023 modeling. For details, refer to
Appendix B of the 2023 Notice of Intent.

2.0 MODEL DESCRIPTION/JUSTIFICATION
AERMOD is one of the most frequently used regulatory dispersion models in the United States
since it replaced ISCST3. Based on EPA guidance, AERMOD (version 23132) is the most
appropriate of the EPA-approved models, given the site’s physical characteristics and the
facility emission sources. AERMOD was applied as recommended in EPA’s Guideline on Air
Quality Models and consistent with guidance in UDAQ’s Modeling Guidelines. The BPIP Prime
building downwash algorithm was applied for the facility.
Terrain data were processed consistent with the approved model protocol and EPA guidance
for AERMAP. The United States Geological Survey (USGS) National Viewer was used to obtain
appropriate National Elevation Dataset (NED) data to establish proper elevations. Five years of
meteorological data from the Spanish Fork Airport (2004-2008) was provided by UDAQ for this
analysis. The model receptor network and model domain remain consistent with the 2023
modeling.

3.0 EMISSION AND SOURCE DATA
The maximum annual hour usage was estimated to establish the potential emissions. Table 1
illustrates the projected NOX emission rates for all engines. All engine emission rates listed in Table
1 are based on 2021 performance test results for the Enterprise engines and manufacturer
information for the Caterpillar engines. The Enterprise engines have the capacity of running on
diesel fuel 1% of the time during typical operations. The NOx factors are from test data and
account for the 1% diesel. As stated above the worst-case average test results plus a safety
factor were 1.485 g/kw-hr. The maximum horsepower assumed for both Enterprise engines is

All Caterpillar engine emissions are derived from specification data from the manufacturer. The
CAT G3520H units are 3,422 hp each at the site elevation. Each engine is specified to emit 1
g/hp-hr for NOx, but the SCR controls all NOx by 93% or a factor of 0.07 g/hp-hr. However, due to
a potential SCR startup time of 7 minutes, potential emission rates vary. The hourly emission rate

4.0 RECEPTOR NETWORK
The facility is located in a rural area in Springville, Utah within Utah County. Consistent with
UDAQ Air Dispersion Modeling Guidance, the ambient air boundary used in this analysis is the
owned property boundary, which also serves as the Public Access Boundary (PAB). Springville
owns the area south of 700 North and can control access. Receptors along the PAB were
spaced at 25 meter increments. The PAB represents the limit of access by the public to the
project site. The receptor grid was established as follows:
• Receptors spaced at 25 meters along the PAB;
• Receptors spaced at 25 meters for the first 100 meters past the PAB;
• Receptors spaced at a density of one per 50 meters from 100 meters out to 350 meters
past the PAB;
• Receptors spaced at 100 meters from 350 out to 850 meters past the PAB;
• Receptors spaced at 250 meters from 850 out to 1,850 meters past the PAB;
• Receptors spaced at 500 meters from 1.85 kilometers out to 4.35 kilometers past the PAB;
and
• Receptors spaced at 1 kilometer from 4.35 kilometers out to 7.35 kilometers past the PAB.
5.0 ELEVATION DATA
All source base and receptor elevations were calculated from USGS NED data obtained via the
National Map Viewer website using the Bee-Line BEEST preprocessing system. A 1/3 arc second
NED file was used in the analysis input and output files from AERMAP and will be included
submitted with the report.

Land use Classification

7.0 LAND USE CLASSIFICATION
AERMOD includes rural and urban algorithm options. These options affect the wind speed
profile, dispersion rates, and mixing-height formula used in calculating ground-level pollutant
concentrations. A protocol was developed by USEPA to classify an area as either rural or urban
for dispersion modeling purposes. The classification is based on average heat flux, land use, or
population density within a three-km radius from the plant site. Of these techniques, the USEPA
has specified that land use is the most definitive criterion (USEPA, 1987). The urban/rural
classification scheme based on land use is as follows:
The land use within the total area, A0, circumscribed by a 3-km circle about the source, is
classified using the meteorological land use typing scheme proposed by Auer (1978).
The classification scheme requires that more than 50% of the area, A0, be from the
following land use types in order to be considered urban for dispersion modeling
purposes: heavy industrial (I1); light-moderate industrial (I2); commercial (C1); single-
family compact residential (R2); and multi-family compact residential (R3). Otherwise, the
use of rural dispersion coefficients is appropriate.
The Springville facility is located in a light industrial area, at Springville, Utah surrounded by
residential areas to the south and east. To the north is light industrial and agriculture land to the
west. Site and map reconnaissance showed that the area A0 within a 3-km radius of the source is
likely at or slightly above the 50% urban land use criteria necessary for use of urban dispersion
coefficients. Thus, they were applied in the dispersion modeling. The estimated 2023 population2
of Springville of 35,471 was implemented. Default roughness was assumed.

8.0 BACKGROUND CONCENTRATIONS
NO2
Starting in 2018, NO2 and ozone monitors were placed in Spanish Fork (AQS Site ID 49-049-5010).
The AERMOD Wizard tool associated with the BEEST software was used to obtain three years of
NO2 and ozone data from the monitor. The years are 2019-2021. 2022 was not selected because
the tool doesn’t have the full year available for download. The data was then processed with the
tool to establish the appropriate 1-hr background values for both NO2 and ozone. The ozone data
completeness by quarter was 98.86% or greater for each of the three years (NO2 was 98.90%).
The 1st high values were determined for the temporal array flag of MHRDOW7 (month hour of day,
seven days per week). This was selected to allow for the most representative values throughout
the evaluation period. This is fairly consistent with the 2017 UDAQ modeling that used hourly files.
AERMOD input SO format files are provided as are text files. Note the NO2 file had missing data on
Friday hour 5 and Sunday hour 5 for all months. Similarly, the ozone file had missing data for
Saturday hour 5 for all months, but December. The average of the preceding and following
concentrations was applied for the missing data.
The ozone limiting method was applied as part of this analysis, again to remain consistent with
2017 modeling. Note that this approach is unchanged from the 2023 modeling.
NO2 In-Stack Ratio
Lastly, a representative NO2/NOx in-stack ratio of 0.1 for each Enterprise engine and the boiler
was applied to remain consistent with the 2017 UDAQ modeling. The 0.1 is also a reasonable
value for natural gas combustion on average per the EPA In-stack Ratio database3.
Lastly, an average of three Caterpillar G3520 engines as referenced in the EPA In-stack Ratio
database was applied for the G3520H units. This number is 0.1625 from previously tested units by
the Oklahoma DEQ.

9.0 RESULTS
The following sections outline the methods used to complete an ambient air impact analysis as a
result of the proposed Springville project.
9.1 APPLICABLE LIMITS
The air quality impact limits applicable to this analysis are the National Ambient Air Quality
Standards (NAAQS). NO2 uses the design value that is the 98th percentile averaged over three
years. That equates to a design value that is the 8th high over a five year period.
9.2 IMPACT
The tables shown below demonstrate that there is no exceedance of the 1-hr NO2 NAAQS
standards due to the proposed operation of the facility.
