SOURCE INFORMATION
General Description
Sunroc Corporation (Sunroc), located in the Fort Pierce area in St. George, Washington County, operates
aggregate, concrete batching, and hot mix asphalt operations at its Fort Pierce Pit. Aggregate is harvested
via drilling and blasting of the rock formations and then fed into crushers and screens. Aggregates cycle
through the crushers and screens to achieve appropriate sizing and are stored on location before being
trucked off site or to the asphalt plant or concrete batch plant. The asphalt plant mixes aggregate, asphalt
oil, lime, and fly ash to produce hot mix asphalt. The concrete batch plant mixes cement, fly ash, and
aggregate to create ready-mix concrete. The manufactured asphalt and concrete are trucked to customers.
Sunroc uses bulldozers, front-end loaders, aggregate haul trucks, hot mix asphalt trucks, and concrete
delivery trucks in its production process.

The plant produces up to 600,000 tons of aggregate materials, 405,000 tons of hot mix asphalt product,
and 225,000 cubic yards of concrete per year.

SOURCE INFORMATION
General Description
Sunroc Corporation (Sunroc), located in the Fort Pierce area in St. George, Washington County, operates
aggregate, concrete batching, and hot mix asphalt operations at its Fort Pierce Pit. Aggregate is harvested
via drilling and blasting of the rock formations and then fed into crushers and screens. Aggregates cycle
through the crushers and screens to achieve appropriate sizing and are stored on location before being
trucked off site or to the asphalt plant or concrete batch plant. The asphalt plant mixes aggregate, asphalt
oil, lime, and fly ash to produce hot mix asphalt. The concrete batch plant mixes cement, fly ash, and
aggregate to create ready-mix concrete. The manufactured asphalt and concrete are trucked to customers.
Sunroc uses bulldozers, front-end loaders, aggregate haul trucks, hot mix asphalt trucks, and concrete
delivery trucks in its production process.

The plant produces up to 600,000 tons of aggregate materials, 405,000 tons of hot mix asphalt product,
and 225,000 cubic yards of concrete per year.

NOTICE

A Notice of Intent for the following project submitted in accordance with R307-401-1, Utah
Administrative Code (UAC), has been received for consideration by the Director:

Company Name: Sunroc Corporation
Location: Sunroc Corporation - Fort Pierce Pit – 1825 E 3850 S, St. George, UT
Project Description: Sunroc Corporation (Sunroc), located in the Fort Pierce area in St. George,
Washington County, operates aggregate, concrete batching, and hot mix asphalt
operations at its Fort Pierce Pit. Aggregate is harvested via drilling and blasting
of the rock formations and then fed into crushers and screens. Aggregates cycle
through the crushers and screens to achieve appropriate sizing and are stored on
location before being trucked off site or to the asphalt plant or concrete batch
plant. The asphalt plant mixes aggregate, asphalt oil, lime, and fly ash to produce
hot mix asphalt. The concrete batch plant mixes cement, fly ash, and aggregate
to create ready-mix concrete. The manufactured asphalt and concrete are trucked
to customers. Sunroc uses bulldozers, front-end loaders, aggregate haul trucks,
hot mix asphalt trucks, and concrete delivery trucks in its production process.

Sunroc has requested a modification to the Fort Pierce Facility Approval Order.
Sunroc has proposed to decrease processed aggregate production by 60,000 tons
per year (tpy) for a total of 600,000 tpy, and to increase hot mix asphalt (HMA)
production by 105,000 tpy, for a total of 405,000 tpy.

The completed engineering evaluation and air quality impact analysis showed the proposed project meets
the requirements of federal air quality regulations and the State air quality rules. The Director intends to
issue an Approval Order pending a 30-day public comment period. The project proposal, estimate of the
effect on local air quality and draft Approval Order are available for public inspection and comment at the
Utah Division of Air Quality, 195 North 1950 West, Salt Lake City, UT 84116. Written comments
received by the Division at this same address on or before April 10, 2024 will be considered in making
the final decision on the approval/disapproval of the proposed project. Email comments will also be
accepted at [e-mail]. If anyone so requests to the Director in writing within 15 days of
publication of this notice, a hearing will be held in accordance with
R307-401-7, UAC.

Under Section 19-1-301.5, a person who wishes to challenge a Permit Order may only raise an issue or
argument during an adjudicatory proceeding that was raised during the public comment period and was
supported with sufficient information or documentation to enable the Director to fully consider the
substance and significance of the issue.

SUBJECT: Modeling Analysis Review for the Notice of Intent for Sunroc Corporation –
Ft. Pierce Facility, Washington County, Utah.
____________________________________________________________________________________________
This is not a Major Prevention of Significant Deterioration (PSD) Source.

I. OBJECTIVE
Sunroc Corporation (Sunroc) is seeking an approval order for their Ft. Pierce Pit located near
St. George, Utah. Sunroc has requested a modification to the Fort Pierce Facility Approval
Order. Sunroc has proposed to decrease processed aggregate production by 60,000 tons per
year (tpy) for a total of 600,000 tpy, and to increase hot mix asphalt (HMA) production by
105,000 tpy, for a total of 405,000 tpy.

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.

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 formaldehyde triggered the
requirement to model under R307-410-5. Modeling was performed by the UDAQ.

B. Assumptions

1. Topography/Terrain

The Plant is at an elevation 2642 feet with terrain features that have no effect on
concentration predictions.

a. Zone: 12

b. Approximate Location:

UTM (NAD83): 273518 meters East
4102692 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

Four (4) years of off-site surface and upper air data were used in the analysis
consisting of the following:

Surface – St. George, UT UDAQ: 2004-2007
Upper Air – Desert Rock, NV NWS: 2004-2007

DAQE-MN125160009-23
Page 3
6. Background

No background concentrations were used in the model.

7. Receptor and Terrain Elevations

The modeling domain used 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.

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.

9. Air Pollutant Emission Rates

Emission Factor Source: Control of Fugitive Dust Sources (EPA-450/3-88-008) dated September, 1988 for wind emissions from continuously active storage piles: 2b. Per AP-42
Section 13.2.4 (Aggregate Handling and Storage Piles) dated November, 2006, the particle size multiplier, k, used for calculating PM10 and PM2.5 emission factors are as follows:
Total Suspended Particulate Emission Factor (E, lb/acre/day) = 1.7 x (s/1.5) x ((365-p)/235) x (f/15) s =
material silt content (%) = 6.9
f = % of time the unobstructed wind speed exceeds 12 mph at the pile height = 2.45
p = days per year with at least 0.01 inches of precipitation = 33.6

RE: Sunroc Corporation Fort Pierce Facility – Request to Modify Approval Order DAQE-
AN125160008-21

Mr. Humpherys,

Sunroc Corporation (SRC) operates the Fort Pierce facility located at 1825 East 3850 South in St.
George, UT. The facility performs aggregate mining, aggregate processing, concrete batching, and hot
mix asphalt production at the site and operates under Approval Order (AO) DAQE-AN125160008-21
(Facility Figure in Appendix B).

SRC proposes a minor modification to the AO as detailed in this application. The proposed
modifications consist of the following:

• Decrease the aggregate material production from 660,000 Tons Per Year (tpy), to 600,000 tpy
• Increase the hot mix asphalt plant production from 300,000 tpy to 400,000 tpy
o No change to the hourly maximum rating of 500 ton/hr is proposed

The proposed modification will result in a sitewide Potential to Emit decrease in PM10, Nitrogen Oxides,
Sulfur Dioxide, Carbon Monoxide and VOCs. The modification will result in a slight increase in annual
HAPs and PM2.5. Detailed emission calculations are provided in Appendix C of the application. Hourly
emissions of HAPs are not increasing as a result of this modification so no modeling was triggered.

Best Available Control Technologies (BACT) were evaluated for the hot mix asphalt plant to ensure
economically feasible and available controls are in place for the facility. These analyses are presented
in Appendix D of the application.

If you have any questions regarding this submittal or need additional information, please feel free to
contact me at [phone] or [e-mail].

Sincerely,

Kamren Garfield

6. Non-fugitive sources (point sources) include transfer of cement and cement supplement, weigh hopper loading and truck mix loading, the
emissions from which are controlled by a bin vent.
1. Uncontrolled Emission Factor source for TCBP-1 through TCBP-6: AP-42 5th Ed., Final Section 11.12 updated June 2006, Table 11.12-2.
Controlled Emission Factors for these sources/ activites are not provided in AP-42 Section 11.12
2. Controlled Emission Factor source: AP-42 5th Ed., Final Section 11.12 updated June 2006, Table 11.12-2. Emissions are controlled by baghouse/bin vent.
3. Because a controlled emission factor is not provided in Table 11.12-2 for this activity, a control factor, which assumes 75% control from bin vent was applied to the
uncontrolled emission factor. Uncontrolled Emission Factor source: AP-42 5th Ed., Final Section 11.12 updated June 2006, Table 11.12-2.
4. Emission Factor source: AP-42 5th Ed., Final Section 11.12 updated June 2006. Truck Mix loading operations PM2.5 emission factors are based on the
PM10 emission factor in Table 11.12-2 and k parameters from Table 11.12-3. Emission factors are calculated as follows: EF for PM2.5 in lb/ton = EF for PM10
in lb/ton x (kPM2.5/kPM10) = 0.016 x 0.048 / 0.32 = 0.0024 lb/ton for PM2.5.
5. Fugitive sources include aggregate and sand transfer operations

ATTACHMENT D: BACT ANALYSES

Appendix C – BACT Analyses

BACT for Hot Mix Asphalt Plant Dryer
The dryer drum and burner operations are the main source of pollution at the hot mix asphalt
plant. Combustion emissions from the dryer include products of complete and incomplete
combustion. Products of complete combustion include oxides of nitrogen (NOx) and, if sulfur is
present in the fuel, sulfur dioxide (SO2) and other substances such as carbon dioxide (CO2)
and water. Products of incomplete combustion include carbon monoxide (CO), volatile organic
compounds (VOCs) and other organic particulate matter. The drum dryer at the Fort Pierce
facility is fired on natural gas.

C.1 BACT for VOC, CO, SO2, and HAPs
For the drum dryer, two control technologies were identified for reduction of criteria combustion
and HAP emissions. These include: (1) work practice requirements of good combustion
practice; and (2) use of low sulfur gaseous fuels.
Incomplete combustion emissions result from improper air and fuel mixtures, such as poor
mixing of fuel and air, inadequate fuel air residence time and temperature, and quenching of the
burner flame. Thus, NOx, VOC, CO, and HAP emissions will be reduced by ensuring good
combustion practices are utilized which include periodic dryer burner tune-up and proper burner
maintenance to increase the efficiency of the burners and operation of the dryer burner in
accordance with manufacturer specifications. In addition, natural gas is a low sulfur fuel which is
utilized on-sit. Thus, BACT for minimizing dryer drum VOC, CO, SO2 and HAP emissions is
good combustion practices and use of pipeline grade natural gas.

C.2 BACT for PM10/PM2.5
Emissions from the asphalt plant dryer also include PM10/PM2.5 from the aggregate and a
small amount from fuel combustion. Several add-on technologies were identified for reduction
on PM10 and PM2.5 and include: (1) Cyclones; (2) Multiple cyclones; (3) Settling chambers; (4)
Fabric filter baghouses; (5) Wet gas venturi scrubbers, and (6) good combustion practices.
Venturi wet gas scrubber and fabric filter baghouses are most efficient in reducing PM10/PM2.5
emissions with control efficiencies ranging from 90 - 99.5%. Multiple cyclones have a control
efficiency of approximately 90%, and cyclones have a control efficiency from 50 to 75%. Settling
chambers are least efficient with a control efficiency of less than 50%.
For the asphalt plant dryer at Fort Pierce, PM10/PM2.5 emissions will be controlled using a
fabric filter baghouse with a control efficiency of 98% or greater. In addition, SRC will maintain
the baghouse in good working order and will monitor bag filter pressure drop as required in the
AO. The baghouse represents BACT for PM10/PM2.5 emissions from the HMA plant dryer

C.3 BACT for NOx
NOx is controlled through burner design, use of quality fuels, and properly maintaining the
burner.
After searching several types of burners available, it was determined the lowest emitting burner
of adequate size on the market is certified to 40 ppm NOx, which equates to 0.012 lbs NOx/ton
of production (corrected to 3% O2)
The Fort Pierce asphalt plant currently uses a Hauck Eco Star II burner. Hauck has since been
acquired by Honeywell, and efforts to obtain NOx certification documentation from Honeywell
have not yielded any useful information regarding emissions. While likely an overestimation, AP-
42 emission factors were used to determine NOx emissions in the economic analysis due to
lack of better information.

Based on the high cost per ton of pollutant reduction of an ultra-low NOx unit, SRC has
determined BACT as good combustion practices with the current plant burner, while firing on
pipeline grade natural gas.
