paver, 120,000 tons of concrete blocks, and 627,000 tons of pre-packaged cement, concrete, and mortar/stucco materials, per rolling 12-month period. NSR Classification: Minor Modification at Minor Source Source Classification Located in Northern Wasatch Front O3 NAA, Salt Lake City UT PM2.5 NAA Davis County Airs Source Size: B
Applicable Federal Standards NA
Project Proposal Modification to AO DAQE-AN143660002-21 to Increase Production and Add a Wet Processing Line
Project Description Amcor has requested to make the following changes: 1. To increase dry ingredient throughput at the paver and block plants. The paver plant throughput will increase from 275,000 to 300,000 tpy; the block plant throughput will increase
from 101,500 to 120,000 tpy. 2. To add a new wet processing line in the bagging plant. The site-wide emissions will be updated to reflect these changes. EMISSION IMPACT ANALYSIS All criteria pollutant emission increases are below the modeling thresholds contained in R307-410-4. All HAP emission increases are below their respective threshold values in R307-410-5. Therefore, no modeling is required from this source. The DAQ modeling staff conducted in-house modeling on 24-hr PM10. The predicted total PM10 concentrations are less than the NAAQS. Therefore, no new requirements were added to the ER.

Review of BACT for New/Modified Emission Units 1. BACT review regarding new equipment and processes The new wet processing line The material going through the wet processing line is already wet. The conveyor that transports the wet material will be covered and will be limited to 7% opacity at the transfer points. The
Minor NSR Section considers the wet material, the cover, and the opacity limit as BACT. Production increases at the paver and block plants Production increases would cause emissions to increase. The total particulate emissions increases are estimated at less than 0.03 tpy. The control measures under II.B.4 and II.B.5 in the current AO
would be still adequate to control such small emissions increases. Therefore, The Minor NSR Section considers the current conditions and requirements in the AO as BACT. [Last updated August 14, 2024]

DATE: November 26, 2024

SUBJECT: Modeling Analysis Review for the Notice of Intent for Amcor Masonry Products –
Masonry Products Plant, Davis County, Utah
_____________________________________________________________________________________
This is not a Major Prevention of Significant Deterioration (PSD) Source.
I. OBJECTIVE
Amcor Masonry Products (Amcor) is seeking an approval order for their Masonry Products Plant
located in Davis County, Utah. Amcor is a facility consisting of a concrete paver plant, a concrete
block plant, and a pre-packaged cement bagging plant. Operations include silo loading, material
drying, mixing, and packaging materials. The plants will produce up to 300,000 tons of concrete
paver, 120,000 tons of concrete blocks, and 627,000 tons of pre-packaged cement, concrete, and
mortar/stucco materials, per rolling 12-month period.

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. Modeling was performed by the UDAQ.

B. Assumptions

1. Topography/Terrain

The Plant is at an elevation 4221 feet with terrain features that have no affect on
concentration predictions.

a. Zone: 12
b. Approximate Location:
UTM (NAD83): 421668 meters East
4520954 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: 2017-2021
Upper Air – Salt Lake Airport, UT NWS: 2017-2021

6. Background
The background concentrations were based on concentrations measured at the UDAQ
Technical Center.

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.
DAQE- MN143660003-24

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.

NORTH SALT LAKE, UTAH
FACILITY ID: 14366
Approval Order: DAQE-AN143660002-21
Kleinfelder Project No. 20233875.001A

Dear Mr. Humphreys:
On behalf of Oldcastle Amcor Masonry Products Concrete Masonry Products Manufacturing
Plant (Amcor), Kleinfelder, Inc. is submitting this air Approval Order (AO) amendment application
to the Utah Department of Environmental Quality (UDEQ) Division of Air Quality (DAQ) for the co-
located cement bagging, concrete block, and paver facilities located at 333 South Redwood Road,
North Salt Lake, Utah. Attachments to this letter include process flow diagrams, approval order
application forms, emission calculations, and supporting documentation. The following provides
background information, the process description, and emission summary.
BACKGROUND AND PROJECT DESCRIPTIONS
The facility is currently covered under existing AO DAQE-AN143660002-21. The facility consists
of a concrete block plant (Besser Plant), concrete paver plant (Masa Plant), and a pre-packaged
cement bagging plant. Operations performed at the facility include silo loading, material drying,
mixing, and packaging material. Process flow diagrams for each plant are included in Attachment
A.
The facility plans to make the following changes as part of this AO modification application:
- Increase dry ingredient throughput at the block and paver plants.
- Addition of a wet processing line in the bagging plant
- Addition of three additional silos and removal of one existing silo
Each change is discussed in more detail in the subsequent sections.
20233875.001A | CLT23O161015 Page 2 of 5 November 21, 2023

INCREASED THROUGHOUTS
The facility plans to increase dry ingredient throughputs at the block and paver plants as described
below.
- Increase throughput at paver plant from 275,000 tons/year (tpy) to 300,000 tpy
- Increase throughput at block plant from 101,500 tpy to 120,000 tpy
Limited actual emission calculations have been updated to reflect these increased throughputs.
Emissions of all criteria pollutants remain below major thresholds. In addition, emissions
increases of criteria pollutants associated with increased throughputs are below modeling
thresholds contained in R307-410-4.
There are no changes to throughputs to the curing chamber (II.A.14) or dryer (II.A.17), therefore
there are no increases in hazardous air pollutant (HAP) emissions associated with his application.
Emissions are discussed in subsequent sections and are also presented in Attachment C.
NEW WET PROCESSING LINE
An additional wet processing line in the bagging plant was inadvertently left out of the initial
approval order application. This line has a throughput of 1,000 tpy of dry material. The conveyor
to this line is outdoors and is not enclosed. Emissions from this line have been added to the
bagging plant and are presented in the emissions calculations in Attachment C.

SILO MODIFICATIONS
Amcor plans to install 3 additional silos at their facility as well as remove one existing silo. See
below for a list of silos associated with each plant. Silos listed in bold are new and silos that are
crossed out have been removed.
II.A.5: Paver Facility Silos

o Two (2) Lime/Cement Silos
Control: Baghouses
o Four (4) Various Aggregate Storage Silos
Control: Bin Vents (Powered)
The portable tanker silo is a Retesa Model CT-7622 with a capacity of 30,670 gallons. The silo
emissions will be routed to the bin vent of an existing lime or cement silo. The silo may move
throughout the facility, depending on storage needs.
The two new silos in the bagging plant are DSS 350-barrel 1400CF silos that are being moved
from another Amcor facility. The silos will be equipped with Air Max 150 Dust Collectors. Silo and
dust collector spec sheets are located in Attachment D.
Due to changing storage needs, the facility requests the flexibility to store various materials in
their existing and new silos including cement, fly ash, and natural pozzolan and lime without
submitting an AO modification. Overall emissions from the facility will not change based on
storage changes within individual silos since the silo capacities and control devices will not
change.

[4] Emissions from point sources
[5] PM2.5 is 29.4% of PM10 based on Ch 11 in AP-42 and Appendix B-2 for concrete batch plants
BEST AVAILABLE CONTROL TECHNOLOGY (BACT) ANALYSIS
Silos
New silos will be equipped baghouses to control emissions. The baghouses have >99% removal
efficiencies for particulate matter and are considered BACT.
The new portable silo will have its emissions routed to a passive fabric filter bin vent on an existing
silo at the facility. The bin vent removes 99% of particulate matter emissions and is considered
BACT.
Transfer Conveyors
Particulate emissions occur due to conveyor transport operations. The new conveyor in the wet
processing line is not enclosed nor does it have water sprays since the material is already wet.
The conveyor must maintain an opacity of 7%.
REGULATORY APPLICABILITY
State Rules
R307-312 Aggregate Processing Operations for PM2.5 Nonattainment Areas
Rule 307-312 limits concrete batch plants to 7% opacity. The use of proper dust collection and
control, transfer procedures, and paved haul roads will ensure the facility operations remain below
this limit.

R307-410-4 Modeling of Criteria Pollutant Impacts in Attainment Areas
Emissions from the facility remain below modeling thresholds under R307-410-4 as noted in
Attachment C.
