Dear Ms. Zapp:

Re: Request for Evaluation of Compliance with Rule R307-401-9, UAC: Small Source Exemption
Project Fee Code: N159540002

On January 3, 2025, the Division of Air Quality (DAQ) received your request for a small source
exemption for EDSCO Fasteners, LLC’s Fastener Manufacturing Plant. The source is located at 3562
North 600 West, Units 8-13 in Spanish Fork, Utah County. The DAQ has determined the small source
exemption applies to the source, as long as the equipment and associated processes operate as specified in
the registration request. Specifically, the source shall cut no more than 8,320 tons of low carbon steel
annually in the plasma cutter and shall use no more than 1,000 pounds of abrasive blasting media per
hour.

The small source exemption does not exempt a source from complying with other applicable federal,
state, and local regulations and the current Utah Administrative Code. Based on the emissions that you
submitted to the DAQ with your registration request, EDSCO Fasteners, LLC’s Fastener Manufacturing
Plant is not required to obtain an approval order under R307-401. If you change your operation such that
there is an increase in emissions, we recommend that you notify us, as an approval order may be required.

As authorized by the Utah Legislature, the fee for issuing this small source exemption is a one-time filing
fee in addition to the actual time spent by the review engineer and all other staff on the project. Payment
should be sent to the DAQ upon receipt of the invoice.

Subject: Evaluation of Small Source Exemption for a Zinc Galvanizing Process at
EDSCO Fasteners, LLC

Dear Ms. Zapp:
Yorke Engineering, LLC (Yorke) is pleased to provide Commercial Metals Company (CMC) with
this small source exemption evaluation for the anchor bolt and fastener manufacturing process at
EDSCO Fasteners, LLC (EDSCO).
BACKGROUND
In July 2018, EDSCO submitted a Small Source Exemption Registration to Utah’s Department of
Environmental Quality Division of Air Quality (DAQ) to confirm exemption from requiring an air
permit for their anchor bolt and fastener manufacturing process in Spanish Fork, Utah. Since 2018,
CMC has acquired EDSCO and requested that Yorke perform an evaluation of the previously
submitted exemption registration. This study includes a review of the previous evaluation,
including a description of the equipment and a summary of the relevant Utah rules and regulations
with respect to equipment permitting.
Equipment Description
EDSCO is a manufacturer and distributor of anchor bolts and fasteners for large steel structures.
Raw materials are received by the facility, where they are processed with hand-held machines to
create anchor bolts and fasteners. The bolts and fasteners are then processed through abrasive
blasting cabinets and dipped into a galvanizing kettle for a zinc coating. Zinc alloy ingots of at
least 99.995% zinc are melted in the galvanizing kettle heated by two 0.75 million British thermal
units (MMBtu) per hour burners fueled by natural gas. The kettle’s capacity is 3,600 pounds and
processes an average of 43,713 pounds per year of zinc. Plasma arc cutting stations are located at
the site to cut raw materials as well as other material for maintenance-related purposes.
SMALL SOURCE EXEMPTION REGISTRATION SUMMARY
This section includes a listing of the DAQ’s Small Source Exemption Registration requirements
that are potentially applicable to the metal processing, abrasive blasting, and zinc galvanizing
equipment.
Rule 307-401-9 – Small Source Exemption
Rule 307-401 identifies operations that emit small quantities of air contaminants that may be
exempted from requiring an approval order.
Ms. Ashley Zapp
May 22, 2024
Page 2 of 5

Rule 307-401-9 provides the requirements for a small source exemption from the application and
permitting for new installations and modifications to existing installations throughout the State of
Utah. Small stationary sources are exempt from the requirement to obtain an approval order
through the requirements of Rule 307-401-5 through 8, including Notice of Intent, Review Period,
and Public Notice, if the following conditions are met:
 Rule 307-401-9(1)(a): The small stationary source’s emissions are less than 5 tons per year
per criteria air pollutant [sulfur dioxide (SO2), carbon monoxide (CO), nitrogen oxides
(NOx), particulate matter less than 10 microns in size (PM10), ozone (O3), or volatile organic
compounds (VOCs)];
 Rule 307-401-9(1)(b): The small stationary source’s emissions are less than 500 pounds per
year of any hazardous air pollutant (HAP) and less than 2,000 pounds per year of any
combination of HAPs; and
 Rule 307-401-9(1)(c): The small stationary source’s emissions are less than 500 pounds per
year of any air pollutant not listed in Rule 307-401-9(1)(a) or Rule 307-401-9(1)(b) above
and less than 2,000 pounds per year of any combination of air pollutants not listed above.
The following section presents the emission calculations from EDSCO used to determine
compliance with Rules 307-401-9(1)(a-c).
EMISSION CALCULATIONS
Rule 307-401-9(1)(a) limits the quantity of criteria pollutant emissions emitted from any small
stationary source, and Rule 307-401-9(1)(b) limits the quantity of HAP emissions emitted from
any small stationary source. Rule 307-401-9(1)(c) limits the quantity of air pollutants not included
in Rule 307-401-9(1)(a) or Rule 307-401-9(1)(b). Emissions of criteria pollutants must be less
than 5 tons per year. HAPs and non-HAP toxic air contaminants are limited to 500 pounds per
year per pollutant and less than 2,000 pounds per year of combined pollutants (HAPs and non-
HAPs, compared separately). Criteria pollutants, HAPs, and non-HAP toxics are emitted from
EDSCO as a byproduct of the metal cutting, abrasive blasting, natural gas combustion, and the hot
dip galvanizing process. Methods for calculating emissions from EDSCO are reviewed below.
Metal Cutting
EDSCO receives various raw materials, which are processed through six cutting stations
prior to processing. In 2018, emissions from metal cutting were calculated using AP-42
Section 12.5.1 emission factors for billet cutting torches. Upon review, the facility
confirmed that plasma arc cutters are used to cut all material at the facility. Emissions are
calculated for the plasma cutters as described below.
PM10 is emitted from the plasma cutting operations. Emissions were calculated using
emission factors from the 1994 Swedish Institute of Production Engineering Research1.
Since the cutting occurs over a water table, the semidry emission factor was used which
assumes 99.5% of the material cut remains in the table, and the remaining 0.5% is emitted
as fumes. An estimated 5% of the total material is removed during cutting. The emission

calculations assume that all raw materials are processed in the plasma cutters and are
assumed to not contain any stainless steel. Metal HAPs emissions were calculated
assuming a general metals speciation profile for mild steel. Emission calculations for the
plasma cutters are shown in Attachment 4.
Abrasive Blasting
The abrasive blasting process occurs in two small, enclosed blast cabinets, after raw
materials are cut and processed into anchor bolts and fasteners, in preparation for the hot
dip galvanizing process. In 2018, PM10 emissions from abrasive blasting were calculated
using AP-42 Section 13.2.6 emission factors for abrasive blasting operations. More
detailed emissions can be calculated with more specific information on each abrasive
blasting station, including the blasting nozzle diameter, outlet pressure, blower rating, and
dust collection control efficiency. However, the AP-42 emission factors are widely
accepted and are representative of the operations. In this review, PM10 emissions were
calculated the same as in 2018. Metal HAPs emissions were calculated using the metals
speciation of AMASTEEL, the blast media used by the abrasive machines. Emission
calculations for the abrasive blasting stations are shown in Attachment 4.
Galvanizing Kettle – Burners
Bolts and fastener products are dipped into the hot galvanizing kettle for a zinc coating.
The galvanizing kettle is equipped with two burners for melting the zinc ingots. In 2018,
criteria pollutant emissions including NOx, SOx, CO, PM10, and VOCs from galvanizing
kettle combustion were calculated using AP-42 emission factors for natural gas
combustion. Additionally, the burners reviewed in 2018 were two burners rated at 0.5
MMBtu/hr. While the emission factors are representative of the galvanizing kettle burners,
each of the burners currently at the facility is rated at a maximum heat input capacity of
0.75 MMBtu per hour. Criteria pollutant emissions in this analysis are calculated using the
new burner ratings. Speciated HAPs and non-HAP toxics were calculated based on the
speciation profile for natural gas combustion in AP-42 Section 1.4, Table 1.4-3. Emission
calculations for the combustion in the galvanizing kettles are shown in Attachment 4.
Galvanizing Kettle – Hot Dip Galvanizing
The galvanizing kettle process of dipping bolts and fasteners into the galvanizing kettle of
melted zinc ingots produces PM10 emissions. In 2018, PM10 emissions were calculated
using an emission factor from the EPA’s Emissions from Hot-Dip Galvanizing Process2
based on pounds of PM10 per ton of galvanized product. Although the emission factor
used is representative of the process, the facility confirmed that the maximum annual
production of galvanized product is not tracked. Since the annual purchase of zinc is
tracked by the facility, this analysis uses an emission factor from the same source document
in terms of pounds of PM10 per ton of zinc used. Metal HAPs emissions were calculated
assuming the speciation profile for Zinc Special High Grade. Emission calculations for the
galvanizing process are shown in Attachment 4.
Criteria pollutant emissions from the facility are expected to be below the Rule 307-401-9(1)(a)
limits of 5 tons per year per criteria air pollutant for CO, NOx, ROG, SOx, and PM10. All HAP

emissions from the facility are expected to be below the Rule 307-401-9(1)(b) limits of 500 pounds
per year per HAP and 2,000 lbs. per year of combined HAPs. Table 1 below provides a summary

experiencing respiratory distress

4.2 Most important symptoms and effects, both acute and delayed
Acute: None known
Delayed: No delayed symptoms or effects expected

4.3 Indication of any immediate medical attention and special treatment needed
None known

5 FIRE-FIGHTING MEASURES
5.1 Extinguishing Media – Substance will NOT burn.
Substance will melt to molten phase during a sustained fire and will re-solidify when
cooled (melting point 786F/420C). If sustained fire is hot enough substance will boil
(boiling point 1665F/907C) and emit zinc vapor, which converts to zinc oxide (ZnO)
with O2 in ambient air (ZnO is a white powder, see ZnO SDS for more information).
There is no hazard with substance contacting water. However if substance is in fine form
(i.e. powder or dust), water will cause rapid substance degradation to more natural
stable state which is zinc oxide, and this process generates heat and H gas by-product.
For this reason, if substance is on fire, do not use water and water will cause this
degradation process and worsen the fire situation.

Suitable Extinguishing Media Use metal extinguishing media (Class D), CO2, Smother
with sand or dirt
Unsuitable Extinguishing
media
WATER

5.2 Special hazards arising from the substance or mixture
Hazards from the substance Water contaminated with this material must be
contained and prevented from being discharged to

Re: Request for Evaluation of Compliance with Rule R307-401-9, UAC: Small Source Exemption
Project Fee Code: N15954-0001
On August 10, 2018, the Division of Air Quality (DAQ) received your request for a small source
exemption for EDSCO Fasteners LLC - Fastener Manufacturing Plant. The source is located at 1350
Calpac Avenue, Spanish Fork, Utah County. DAQ has determined the small source exemption applies to
the source as long as the equipment and associated processes operate as specified in the registration
request.
The small source exemption does not exempt a source from complying with other applicable federal,
state, and local regulations and the current Utah Administrative Code. Based on the emissions you
submitted to DAQ with your registration request, EDSCO Fasteners LLC Fastener Manufacturing Plant
is not required to obtain an approval order under R307-401. If you change your operation such that there
is an increase in emissions, we recommend you notify us, as an approval order may be required.
As authorized by the Utah Legislature, the fee for issuing this small source exemption is a one-time filing
fee in addition to the actual time spent by the review engineer and all other staff on the project. Payment
should be sent to DAQ upon receipt of the invoice.

ATTACHMENT-PROCESS DESCRIPTION
EDSCO Fasteners, LLC -Spanish Fork, UT (EDSCO) is a manufacturer of anchor bolts and fasteners for
large steel structures. The facility engages in cutting, sawing, welding of metals and is currently intends
to install a zinc galvanizing process at the site, which involves natural gas burners and zinc galvanizing
kettle. The facility is seeking to register these operations in accordance with UAC R307-401-9: Small
Source Exemption Registration.
PROCESS
Facility receives various raw materials via trucks and stored in designated area. The materials are
processed to hand-held machines to manufacture anchor bolts and fasteners for use in large steel
structures. The bolts and fasteners are then processed through small enclosed blast cabinets with dust
collectors. The bolts and fasteners are then processed to dip in galvanizing kettle. The galvanizing kettle
uses atleast 99 .995% zinc ingots. The bolts and fasteners are dipped into hot galvanizing kettle for zinc
coating. The maximum rated capacity of the kettle is 3,600 pounds. The kettle is equipped with two
burners for melting zinc ingots. Each of the burners is rated at the capacity of 0.50 MM BTU/hr and uses
natural gas as fuel. The zinc galvanized products are then packed and stored/shipped.
The facility is seeking small source exemption registration since the actual emissions are 1) less than 5
tpy of each of the following pollutants: sulfur dioxide (502), carbon monoxide (CO), nitrogen oxides
(NOx), particulate matter (PMlO), ozone (03), or volatile organic compounds (VOCs) and 2) less than
500 pounds per year of single HAP and less than 2000 pounds per year of any air combination of HAPs
and less than 500 pounds per year of any air contaminant not listed in (1)( or (2) above and less than
2000 pounds per year of any combination of air contaminants not listed in (1) or (2) above.

2. SUMMARY, CO NCLUSIONS, AND RECOMME NDATIONS
A comprehensive literature search was performed to locate and
identify all sources· of information on emissions from hot-dip galvanizing
proces .ses. O~servat ions of current galvanizing practices, procedures,
and equipment were made in a total of five plant visits -two in
the Los Angeles area and three in the Chicago area. To detennine
accurate emissions of particulates from current galvanizing operations,
the PES staff perfonned three separate source tests, us ing EPA Method
5, on one galvanizing plant in the Los Angeles area.
Particulate emission data from a total of seventeen source tests on
hot-dip galvanizing plants were considered relevant in developing an
emission factor for galvanizing kettles. Fourteen of the source tests
measured both kettle emissions and emissions from control devices; the
control devices tested were mainly water scrubbers and baghouses. There
was no significant differe.nce between the kettle and control device
emissions.
An averaged emission factor based on galvanized product process
wefght was calculated, considering both kettle and control device
emfssfons as one data base:
Em1ss1on factor = 0.26 kg/metric ton ·ga 1van1zed product (a=0.28)
<fcf.'s2 lb/short ton galvanfze-ct-prcidu~)
. ·-________ · --------
or, assuming 8% zfnc by weight in the galvanized product.
Emission factor • 3.3 leg/metric ton of zinc used (c,.• 3.5)
~~6 lb/short ~fnc · used)
It 1s recomnended that an emission factor 1n terms of process weight
be defined per weight of galvanized product, since only this quantity is
nonnally measured by galvanfzfng ·plants.

Dear Mike,
State of Utah Mail -Small Source Exemption (SSE) request
Enqiang He <[e-mail]>
Fri, Aug 17, 2018 at 6:43 PM
The Utah Division of Air Quality has received your SSE request
for your facility at 1350 Calpac Avenue, Spanish Fork, UT 84660.
I was assigned to review your application.
Emission thresholds that qualify a facility to be a small source
should include all emission points in a source. In your case, we
also would like to see any emissions from operations such as
cutting, sawing, blasting, and welding processes.
·Please provide these emissions ASAP but no later than two
I
weeks from today. Let me know if you have any questions.
Thanks.
