Project Description
Amazon Services has requested an update to Approval Order DAQE-AN159810001-19 with the
following changes:
1- Updates to existing apparel printing hazardous air pollutant (HAP) and volatile organic compound
(VOC) emission rates, according to maximum stack test results from stack testing conducted at a similar
Amazon facility on December 17, 2020.
2- Removal of twenty (20) existing sublimation printers (Equipment ID# II.A.4 in AO
DAQE-AN159810001-19) and replace with six (6) direct-to-film (DTF) apparel printers.
Emissions from the existing twenty (20) sublimation printers were estimated to be 4.70 tpy of VOCs and
0.86 tpy of HAPs. Replacing the sublimation printers with six (6) new direct-to-film (DTF) printers
results in 3.95 tpy of VOCs and 0.19 tpy of HAPs (a reduction of 0.75 tpy of VOCs and 0.67 tpy of
HAPs).
Additionally, the annual VOC and HAPs emissions were updated using the new stack testing emission
factors and updated production rates. The side-wide reduction in VOCs and HAPs is 5.82 tpy of 0.88 tpy,
respectively. This project meets the requirements of UAC R307-401-12 Reduction in Air Pollutants and
does not require a public comment period.

REVIEWER COMMENTS
1. Comment regarding Source Emission Estimates and UAC R307-401-12 Applicability:
Amazon re-evaluated its PTE based on updated hours of operation and production throughputs.
Emissions from the printers and printer solvent cleanup are generated through the evaporation of
VOCs and HAPs from the inks. Replacing the existing sublimation printers with new DTF printers
results in a net decrease in VOCs and total HAPs. Therefore, this project qualifies as a Reduction in
Air Pollutants under UAC R307-401-12.
The 2019 AO specified a PTE of 3.86 tpy of glycol ethers and 0.72 tpy of triethylene glycol.
Amazon has indicated that no triethylene glycol and a maximum of 0.96 tpy of glycol ethers will be
emitted as a result of the printer replacement and operational changes. Condition II.B.1.c of the 2019
AO has been updated to reflect the new values.
The 2019 AO did not include HAPs emissions from the natural gas-fired boilers. The PTE has been
updated to include the 0.03 tpy of generic HAPs emitted from the boilers. This does not represent an
increase in actual HAPs emissions as the boiler operations are not changing.
Apparel Printing
VOC emissions from the 24 digital apparel printers are based on maximum stack test results from
stack testing conducted at a similar facility (Amazon DFW5) on December 17, 2020. The VOC
emission rate is 1.41 lb/hr. HAPs emissions are based on VOC Emissions and the maximum weight
percent of HAP in the inks and are equivalent to 0.18 lb/hr. The maximum VOC and HAP weight
content of the inks used during the stack test and used at the Salt Lake City Facility in the digital
apparel printing applications are 42.80% and 12.40%, respectively.
Bases on the stack testing, a maximum of 95% of the VOC and HAPs emissions are captured and
routed to the natural gas-fired dryers to be combusted. 5% of the VOC ad HAPs emissions are
fugitive from handling.
VOC and HAPs emissions from the DTF apparel printers are based on the ink SDS sheets and
manufacturer data. The source estimated emissions from the inks using mass-balance and assumed
the highest VOC and/or HAP content associated with each ink for a conservative estimate.
Apparel Printing Solvent Cleaning
VOCs are emitted from the cleanup solvent for the 24 digital apparel printers. The consumption rate
of solvent is 1,440 gals, annually. The solvent has a density of 8.43 lb/gal and a VOC content of
2.0% by weight. The solvent contains no HAPs.
VOCs are also emitted from the cleanup solvent for the 6 new DTF apparel printers. The
consumption rate of solvent is 230 gals, annually. The solvent has a density of 8.35 lb/gal and a
VOC content of 6.0% by weight. The solvent contains no HAPs.

Non-Apparel Printing
VOC and HAPs emissions from the 12 UV printers and new DTF printers are based on the ink SDS
sheets and manufacturer data. The source estimated emissions from the inks using mass-balance and
assumed the highest VOC and/or HAP content associated with each ink for a conservative estimate.
Non-Apparel Printing Solvent Cleaning
The UV printers are cleaned using solvent. The consumption rate of solvent is 12 gals, annually. The
solvent has a density of 8.45 lb/gal and a VOC content of 100% by weight. The solvent contains no
HAPs.
8 Natural Gas-Fired Dryers
The eight (8) apparel dryers' emissions were estimated with AP-42 Section 1.4 (Natural Gas
Combustion). [Last updated September 20, 2024]
2. Comment regarding NSPS and MACT Applicability:
This plant has no applicability to 40 CFR 60 (NSPS) or 40 CFR 63 (MACT) standards.
Subparts that might apply are NSPS Subparts QQ and FFF and MACT Subparts KK and OOOO.
NSPS Subpart QQ (Standards of Performance for the Graphic Arts Industry: Publication
Rotogravure Printing) does not apply due to the printing process not taking place on a gravure
cylinder.
NSPS Subpart FFF (Standards of Performance for Flexible Vinyl and Urethane Coating and
Printing) does not apply due there being to no coating the materials with vinyl or urethane.
MACT Subpart KK (National Emission Standards for the Printing and Publishing Industry) do not
apply as this is a minor source of HAP emissions and also that there isn't any rotogravure or
flexographic processes taking place.
MACT Subpart OOOO (National Emission Standards for Hazardous Air Pollutants: Printing,
Coating, and Dyeing of Fabrics and Other Textiles) does not apply as the operation does not coat t-
shirts or apparel with elastomers, polymers, or prepolymer materials. [Last updated September 4,
2024]
3. Comment regarding Title V Applicability:
Title V of the 1990 Clean Air Act (Title V) applies to the following:
1. Any major source
2. Any source subject to a standard, limitation, or other requirement under Section 111 of the Act,
Standards of Performance for New Stationary Sources;
3. Any source subject to a standard or other requirement under Section 112 of the Act, Hazardous
Air Pollutants.
4. Any Title IV affected source.
This facility is not a major source and is not a Title IV source. The facility is not subject to 40 CFR
60 (NSPS), 40 CFR 61 (NESHAP), or 40 CFR 63 (MACT) regulations. There are no other reasons
why this source would be required to obtain a part 70 permit; therefore, Title V does not apply to this
facility.

4. Comment regarding Utah Administrative Code Rules:
UAC R307-351 (Graphic Arts)
Condition II.B.1.b of the 2019 AO states that "The owner/operator shall not exceed the VOC content
limits established by R307-351 for any inks".
In a 2020 Full Compliance Evaluation of the site (See memorandum DAQC-1470-20) indicated that
R307-351 did not apply to the source and that condition II.B.1.b. should be removed.
UAC R307-351 (Graphic Arts) applies to graphic arts printing operations located in Box Elder,
Cache, Davis, Salt Lake, Utah, Tooele and Weber counties. Per R307-351-4, "graphic arts printing"
means the application of words and images using the offset lithographic, letterpress, rotogravure, or
flexographic printing process. Digital printing is not included in the definition of graphic arts
printing in this rule. Therefore, UAC R307-351 does not apply to the source and condition II.B.1.b
has been removed.
UAC R307-304 (Solvents Cleaning)
R307-304 applies to solvent cleaning operations within Box Elder, Cache, Davis, Salt Lake, Tooele,
Utah or Weber counties to an owner or operator using 55 gallons or more a year of VOC containing
solvent products, minus exempt materials, for solvent cleaning operations. Per the NOI application,
Amazon will use up to 1,440 gallons annually of solvent for the digital apparel printing operations,
12 gallons annually for the cellphone ring stand operations, and 230 gallons annually for the DTF
apparel printing operations.
R307-304-5 establishes VOC content limits for solvent production. Amazon shall be subject to these
limits.
UAC R307-325 (Environmental Quality, Air Quality (R307-325)
R307-325 applies to all sources located in any nonattainment or maintenance area for ozone. The
source is located in an ozone nonattainment area. This rule applies to the source. [Last updated

Amazon.com Services, Inc. (Amazon) operates a digital printing facility in Salt Lake City, UT.
Production at the site includes apparel and other merchandise printing. The description that
follows includes both existing and proposed equipment and operations.
Existing Apparel Printing Operations
This digital printing operation consists of 24 digital printers and eight (8) natural gas fired dryers.
Blank apparel units (e.g. shirts, aprons, etc.) are manually inserted one at a time into one of the
digital printers. Each printer can accommodate two apparel units simultaneously and up to 60
apparel units per hour. Annual production will be limited to 12,614,400 apparel units per year.
A fixation agent or solution is applied to a unit on a maximum print area of 15” x 18” before inks
are applied. Immediately following the application of the fixation agent or solution, ink is applied
according to order specifications. Upon completion of the printing cycle, the apparel units are
manually transferred one at a time to a dryer. The printers and dryers are sources of Volatile
Organic Compound (VOC) emissions that include Hazardous Air Pollutants (HAP).
Emissions testing during operations at a similar facility has confirmed that no more than 5% of the
potential emissions from the apparel printing operations are fugitive in nature and the remaining
95% will be routed to natural gas fired dryers. Information regarding this emissions testing can be
provided upon request.

Proposed Direct-to-Film (DTF) Apparel Printing
The proposed DTF apparel printing operations consist of six M&R Quatro printers. The printers
are self-contained systems each consisting of a wide format roll-fed inkjet printer, a thermoplastic
polyurethane (TPU) powder applicator, a high-efficiency infra-red dryer, and an electric heat press.
Each printer is capable of printing up to 60 units per hour.
The DTF process begins with the creation of a digital design. Once the design is finalized, it is
printed onto PET film with a digital inkjet printer using cyan, magenta, yellow, black, and white
pigmented aqueous inkjet inks. After printing is complete, and while the ink is still wet, the transfer
is prepared by applying a layer of TPU powder to the print area. Immediately after the TPU powder
has been applied, the final construction of film, ink, and TPU powder is prepared for the transfer
process by running it through the high-efficiency infra-red drying system to cure the ink, and to
fuse the TPU powder to achieve a strong bond between the ink and the fabric, ensuring a durable
and long-lasting print. After printing onto the PET film is complete, the film enters the high-
efficiency infra-red drying system to cure the ink. A garment is placed on a heat press and prepped
for the film transfer. The film transfer is then laid on top of the garment in the correct alignment.
The heat press is used to apply both heat and pressure and causes the design to transfer from the
film onto the fabric. The film remains intact throughout the process.
Materials used in the DTF apparel printing operations include polyethylene terephthalate (PET)
film, TPU powder, and water-based inks. No emissions are expected from the PET film or the TPU
powder based on the process description above (i.e., the PET film remains intact throughout the
process; the TPU powder is consumed in the process). Therefore, the DTF apparel printing
operations are a source of VOC and HAP emissions and are represented as building fugitives. It is
conservatively assumed that 100% of the VOC and HAP constituents in the inks are emitted.
The following table includes the proposed ink usage rates for the DTF apparel printing operations.

Cell Phone Ring Stands
This digital printing operation consists of 12 UV printers. Up to 27 Blank cell phone ring stand
units are placed in pre-cut plastic sheets referred to as jigs. The jigs are manually inserted into one
of the 12 UV printers one at a time. Each printer can accommodate up to 5 jigs per hour. Ink is
dried and cured within the printers using UV LED lamps. The printers are a source of VOC
emissions. Annual production will be limited to 14,191,200 cell phone ring stand units per year.

Best Available Control Technology Review
Apparel Printing
Pollutant Control Analysis - Type Analysis - Determination
Carbon Adsorption System (CAS)Technical Feasibility
CAS has been included in this review because CASs are used
to control VOC emissions. However, a CAS is typically
employed to control vapors from single component VOCs or
simple mixtures. The inks employed for the proposed printing
operations have a VOC speciation that varies significantly from
one color to the next. Additionally, the fixation agent used for
apparel printing contains formic acid which will corrode the
carbon material in the CAS resulting in both ineffective VOC
capture as well as the generation of an additional solid waste
stream at the faciltiy due to the need to frequently replace the
carbon material.
Therefore, Amazon.com Services, LLC (Amazon) asserts that a
CAS is not a technically feasible control technology to be
employed in this situation and should not be considered BACT
for digital printing operations. Review of the various impacts of
employing this control is not warranted.
Flare Technical Feasibility
Flares have been included in this review because flares are
used to control VOC emissions. However, flares are not
typically employed for the purpose of controlling emissions from
printing operations specifically due to the lack of combustibility
of ink vapors. The nature of the flare design and the lack of
combustibility of the ink vapor stream means that unnecessarily
large amounts of natural gas would be required in order to
achieve acceptable ink vapor destruction.
Therefore, Amazon asserts that a flare is not a technically
feasible control technology to be employed in this situation and
should not be considered BACT for digital printing operations.
Review of the various impacts of employing this control is not
warranted.
Low-VOC Inks Technical Feasibility
Low-VOC inks have been included in this review because low-
VOC inks are used to reduce VOC emissions. Printing
operations will use low-VOC inks, however, apparel printing
operations proposed for this site will employ digital ink jet
printers that require proprietary inks from the manufacturer.
These inks may contain as much as 53.1% VOC, depending on
the ink color. A non-proprietary low-VOC ink option is not
available for the proposed apparel operations.
Therefore, Amazon asserts that low-VOC inks are not a
technically feasible control technology to be employed in this
situation and should not be considered BACT for digital printing
operations (apparel only). Review of the various impacts of
employing this control is not warranted.
Technical Feasibility
Water-based inks have been included in this review because
water-based inks are used to reduce VOC emissions. Printing
operations will use water-based inks and the proprietary inks for
apparel printing will contain a minimum of 31.5% water,
depending on the ink color.
Therefore, Amazon asserts that water-based inks are
technically feasible control technology and further impacts will
be evaluated for determining BACT applicability.Energy Impacts There are no energy impacts for this control.
Environmental Impacts
The proprietary, water-based inks require that a solvent be
used within the printers to keep the system unclogged. The use
of this solvent results in liquid waste that requires proper
disposal.
Economic Impacts
Economic impacts are not applicable as the inks to be used are
proprietary to the type of printer and must be sourced from the
manufacturer.

Technical Feasibility
RTO/RCOs have been included in this review because
RTO/RCOs are used to reduce VOC emissions. Unlike flares,
RTO/RCOs are designed to effectively destroy VOC vapors
that are not inherently combustible.
Therefore, Amazon asserts that RTO/RCOs are technically
feasible control technology and further impacts will be
evaluated for determining BACT applicability.
Energy Impacts
An RTO/RCO would require natural gas as fuel and electricity
for any attached monitoring systems and electronics. Assuming
that an RTO with a 5 MMBtu/hr burner and 95% control
efficiency is installed, approximately 43 MMscf/yr of natural gas
would be required. This would equate to approximately 1.55
MMscf natural gas burned for each ton of VOC reduced.
Considering that the proposed apparel printing operations and
other activities at the site are classified as a minor source of
VOCs, Amazon asserts that the additional energy expenditures
to control the proposed amount of VOCs is excessive and
unnecessary.
Environmental Impacts
Natural gas combustion would result in additional NOx
emissions, which is an ozone precursor, as well as additional
emissions of particulate matter. Given the nonattainment status
of the area for PM2.5, avoiding unnecessarily adding to PM
emissions is appropriate.
Considering that the proposed apparel printing operations and
other activities at the site are classified as a minor source of
VOCs, Amazon asserts that the additional environmental
impacts to control the proposed amount of VOCs is excessive
and unnecessary.
Economic Impacts
$217,773.20 / ton
This is both the average cost-effectiveness and incremental
cost-effectiveness because there are no additional costs
associated with the next technically feasible control option
(water-based inks).
Other Considerations
Investment Feasibility Issue - The manufacturer of the inks is
actively working to reduce VOC and HAP content in the inks.
Each new series of inks has been effective in making this
reduction. The latest update was successful in completely
eliminating HAPs from both the yellow and red inks.

other activities at the site are classified as a minor source of
VOCs and given that the manufacturer's successful efforts to

Low-NOx Burners Technical Feasibility
Low-NOx burners have been included in this review because
low-NOx burners are used to reduce NOx emissions from
natural gas combustion. However, the dryers proposed to be
used at the site have a burner rating of 0.4 MMBtu/hr and are
expected to emit a combined total of 1.37 tons of NOx per year.
The low burner rating and resulting insignificant emissions
makes retrofitting the dryers unnecessary.
Therefore, Amazon asserts that low-NO x burners are not a
technically feasible control technology to be employed in this
situation and should not be considered BACT for digital printing
operations. Review of the various impacts of employing this
control is not warranted.
Sweet Natural Gas Technical Feasibility
Sweet natural gas has been included in this review because
sweet natural gas is used to reduce emissions from combustion
sources. The apparel dryers are designed to burn natural gas.
Amazon asserts that sweet natural gas is technically feasible
control technology and, considering that the dryers are already
designed to accept that fuel, review of the various impacts of
using sweet natural gas is not warranted.
Sweet natural gas is BACT for the dryers proposed for
apparel printing operations.

simple mixtures. The inks employed for the proposed printing
operations have a VOC speciation that varies significantly from
one color to the next. Finally, emissions from non-apparel
printing are insignificant at no more than 0.2 tpy for a single
printer per year.
Therefore, Amazon asserts that a CAS is not a technically
Flare Technical Feasibility
Flares have been included in this review because flares are
used to control VOC emissions. However, flares are not
typically employed for the purpose of controlling emissions from
printing operations specifically due to the lack of combustibility
of ink vapors. The nature of the flare design and the lack of
combustibility of the ink vapor stream means that unnecessarily
large amounts of natural gas would be required in order to
achieve acceptable ink vapor destruction. Finally, emissions
from non-apparel printing are insignificant at no more than 0.2
tpy for a single printer per year.
Therefore, Amazon asserts that a flare is not a technically
Water-Based Inks Technical Feasibility
Water-based inks have been included in this review because
water-based inks are used to reduce VOC emissions. Printing
operations will use water-based inks, however, non-apparel
printing operations proposed for this site will employ digital ink
jet printers that require proprietary inks from the manufacturer.
These inks are not water-based.
Therefore, Amazon asserts that water-based inks are not a
technically feasible control technology to be employed in this
situation and should not be considered BACT for digital printing
operations (non-apparel only). Review of the various impacts
of employing this control is not warranted.

Technical Feasibility
Low-VOC inks have been included in this review because they
are used to reduce VOC emissions. Printing operations will use
low-VOC inks and the proprietary inks for non-apparel printing
will contain a maximum of 27.6% VOC.
Therefore, Amazon asserts that low-VOC inks are technically
feasible control technology and further impacts will be
evaluated for determining BACT applicability.
Energy Impacts There are no energy impacts for this control.
Environmental Impacts
The proprietary, low-VOC inks used in one of the two non-
apparel production lines require that a solvent be used within
the printers to keep the system unclogged. The use of this
solvent results in liquid waste that requires proper disposal.
Economic Impacts
Economic impacts are not applicable as the inks to be used are
proprietary to the type of printer and must be sourced from the
manufacturer.

Control Feasibility Conclusion Low-VOC inks equate to BACT for this operation and will be
employed.
Regenerative Thermal Oxidizer (RTO) or Regenerative Catalytic Oxidizer (RCO)Technical Feasibility
RTO/RCOs have been included in this review because
RTO/RCOs are used to reduce VOC emissions. Unlike flares,
RTO/RCOs are designed to effectively destroy VOC vapors
that are not inherently combustible. However, emissions from
non-apparel printing are insignificant at no more than 0.2 tpy for
a single unit per year. Additionally, no dryers or stacks are
associated with non-apparel printing operations. Using an
RTO/RCO would require Amazon to install forced air ventilation
systems to capture insignificant amounts of VOCs.
Therefore, Amazon asserts that RTO/RCOs not a technically
feasible control technology to be employed in this situation and
should not be considered BACT for non-apparel digital printing
operations. Review of the various impacts of employing this
control is not warranted.
Low-VOC inks are BACT for the proposed non-apparel
printing operations.

Health Effects Review
Air dispersion modeling for Hazardous Air Pollutants (HAP) was not performed in this permit application as the proposed HAP emissions are below the calculated emissions threshold for each pollutant. The
emissions threshold was calculated using the methodology outlined in R307-410-5 (C).
R307-410-5 Table 2 Emissions Threshold Factor for stack emissions was selected for Vertically-Unrestricted Emission Release Points for the acute category with a distance to property boundary of 50 meters
or less.
R307-410-5 Table 2 Emissions Threshold Factor for fugitive emissions was selected for Vertically-Resticted and Fugitive Emission Release Points for the acute category with a distance to property boundary
of 50 meters or less.
Air dispersion modeling for National Ambient Air Quality Standards was not performed in this permit application as the proposed emissions for criteria pollutants was below the ton per year threshold listed it
