B. Assumptions

1. Topography/Terrain

The Plant is at an elevation 5115 feet with terrain features that have an affect on
concentration predictions.

a. Zone: 12
b. Approximate Location:
UTM (NAD83): 410705 meters East
4491561 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 Herriman, 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- MN162210001-24
Page 3
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

Aligned is currently proposing to construct a new data center in West Jordan, Utah. Phase 1 of this data
center is proposed to include one hundred eighty-two (182) 3 megawatt (MW) generators and ten (10) 1
MW office or house generators. In conjunction with this modeling report, Aligned is submitting an NOI air
permit application to UDAQ to obtain an approval order (AO) for the proposed construction.

This modeling protocol and report outline the methodology that Aligned has used in conducting air
dispersion modeling. It describes the results that demonstrate compliance with the NAAQS for one (1)-hour
and annual nitrogen dioxide (NO2) standard. Dispersion modeling has been conducted in accordance with
R307-410-3 and 40 Code of Federal Regulations (CFR) Part 51, Appendix W Guideline on Air Quality Models.
1.2 Project Scope
Aligned’s proposed West Jordan data center consists of a total of one hundred ninety-two (192) emergency
generators. Due to global supply chain and procurement issues surrounding emergency generators, Aligned
is proposing two possible engine types that will be dictated by engine availability at the time of purchase.
Air dispersion modeling has been performed for each of the proposed engine types to demonstrate that the
“worst” impacting scenario will not cause or contribute to the NAAQS. The two proposed engine types are:
CAT C175-16 and CAT 3516E.

Equipment included in the 1-hour and annual NO2 modeling analysis of the proposed West Jordan Facility
are as follows:
Primary Engine Option
► One hundred eighty-two (182) 3.1 MW CAT 175-16 diesel-fired emergency generator engines; and
► Ten (10) 1 MW CAT C32 house diesel-fired emergency generator engines.
Alternate Engine Option
► One hundred eighty-two (182) 3 MW CAT 3516E diesel-fired emergency generator engines; and
► Ten (10) 1 MW CAT C32 house diesel-fired emergency generator engines.
1.3 Plant Layout
The facility location is shown in Figure 1-1, below.

2. AIR DISPERSION MODELING DESCRIPTION
This section describes the air quality dispersion modeling analysis performed to estimate the ambient air
impacts of Aligned’s operation of the Facility. All modeling results were compared to the NO2 NAAQS for the
1-hour and annual averaging period. The objective of the NAAQS analysis is to demonstrate, through air
quality dispersion modeling, that emissions from the Facility do not cause or contribute to an exceedance of
the 1-hour/annual NO2 NAAQS. Six (6) nearby offsite area sources were included at the direction of UDAQ.
Dispersion Modeling was conducted in accordance with R307-410-3 and 40 CFR Part 51, Appendix W
Guideline on Air Quality Models.
2.1 Model Selection
Near-field dispersion modeling was performed using the latest version of the AERMOD modeling system,
version 23132, which is an EPA approved, steady-state Gaussian mathematical plume model. AERMOD is
composed of three (3) modular components: AERMAP, the terrain preprocessor that characterizes the
terrain and generates source and receptor elevations and surrounding hill height scales; AERMET, the
meteorological preprocessor that processes raw surface and upper air meteorological observations for use
by AERMOD; and AERMOD, the control module and modeling processor.
2.2 Meteorological Data
Meteorological data used in the dispersion modeling analysis was processed and provided by UDAQ.1 Data
consists of five (5) individual years (2016 through 2020) of National Weather Service (NWS) surface data
collected at the Salt Lake City Airport that were then concatenated into a five (5)-year file. Concurrent upper
air observations used in AERMET were obtained from the Salt Lake City Airport.
2.3 Terrain Elevations
Terrain elevations for the Facility’s sources, receptors and buildings were determined using National
Elevation Dataset (NED), the primary elevation data product of the United States Geologic Survey (USGS).2
NED data are distributed in geographic coordinates in units of decimal degrees, and in conformance with the
North American Datum of 1983 (NAD 83). The NED used for this analysis is at a resolution of 1/3 arc-
second (about 10 meter) grid spacing. Elevations were converted from the NED grid spacing to the air
dispersion model receptor spacing using the AERMOD preprocessor, AERMAP version 18081. All data
obtained from the NED files was checked for completeness and spot-checked for accuracy.
2.4 Receptors
A modeling domain was developed for the near-field analyses to encompass the location of the maximum
modeled concentration from Aligned’s sources. Discrete receptor locations in AERMOD were based on UTM
coordinates in the NAD83 datum, Zone 12N. An initial modeling grid extending a minimum of 10.0
kilometers from the Facility center was established. The receptor grid was developed to ensure that
maximum pollutant concentrations were captured by the model. The Facility boundary is based on the
existing Facility boundary.
The model receptors consisted of boundary receptors and gridded receptors with the following spacing:

► The ambient air boundary was placed at the Facility property line and consists of discrete receptors
placed at 25-meter intervals.
► The fine grid contains 100-meter spaced receptors extending to at least 1,000 meters from the center of
the Facility.
► The medium grid contains 500-meter spaced receptors extending to at least 5,000 meters from the
center of the Facility.
► The coarse grid contains 1,000-meter spaced receptors extending to at least 10 kilometers from the
center of the Facility.
► Additional receptors were placed on the roads immediately north and south of the facility at 25-meter
intervals.

Figure 2-1 and Figure 2-2 below show the ambient air boundary receptors (shown in purple below) and
gridded off-site receptors (yellow). Figure 2-2 does not show the full extent of the coarse-grid receptors, but
shows their spacing.

2.5 UTM Coordinate System
In all modeling analyses, input and output data files, the locations of emission sources, structures, and
receptors were represented in the Universal Transverse Mercator (UTM) coordinate system and based on
NAD83. In this grid, the world is divided into 60 north-south zones, each covering a strip 6° wide in
longitude. The general area of the site is located in UTM Zone 12N. In each UTM zone, coordinates are
measured north and east in meters. The northing values are measured continuously from zero at the
equator, in a northerly direction. A central meridian through the middle of each 6° zone is assigned an
easting value of 500,000 meters. Grid values to the east of this central meridian, as in the case of the site,
are greater than 500,000 meters.
2.6 Building Downwash
Emission sources were evaluated in terms of their proximity to nearby structures. The following structures
were included for the Building Profile Input Program (BPIP), which predicts the effects of building
downwash:

► Five (5) data center buildings;
► One hundred and ninety-two (192) engine enclosures; and
► One hundred and eighty-two (182) uninterrupted power supply (UPS) housings.

3.NO2 SOURCE PARAMETERS AND EMISSION RATES
3.1 NO2 Point Source Parameters and Emission Rates
All diesel-fired emergency generator engines were modeled as uncapped point sources. Each generator
engine is equipped with several high efficiency control technologies. All point sources require release
height, stack temperature, stack velocity, and stack diameter. This section explains the methodology to
obtain the modelling parameters required for point sources. All inputs for stack source parameters can be
seen in Appendix A of this modeling analysis.
3.1.1 Combustion Equipment Modeling Parameters and Emission Rates
The modeled point sources of NO2 at the Facility consist of the equipment and their release parameters as

3.1.2 Combustion Equipment Operating Parameters
Outside of emergency situations, the diesel-fired emergency generator engines will only operate for testing
and maintenance purposes. Aligned has evaluated various operating scenarios in which operating and
maintenance may be conducted on the diesel-fired generators. Aligned has determined groupings of diesel-
fired generator engines to be operated concurrently for operating and maintenance purposes. Table 3-2
outlines these groupings. The groups were applied to both the primary and alternate engine option
scenarios described in Section 1.2. Operating scenarios are reflected in the corresponding modeling files
submitted with this report.

4. NO2 MODELING ANALYSIS
The NO2 modeling analysis predicts ambient concentrations of NO2 due to emissions from the Facility. The
modeling output includes tabulated modeling results as compared to the NO2 1-hour and Annual NAAQS.
4.1 NO2 Special Processing
The majority of the emissions of NOX from air emission sources are in the form of nitric oxide (NO), whereas
EPA has established a NAAQS for NO2. EPA’s “Guideline on Air Quality Models” describes a three-tiered
screening approach to calculating NO2 concentrations based on dispersion model predictions of NOX
concentrations.

The three tiers, arranged in order from simplest to most refined, are:

• Tier 1 – Assume full conversion of NO to NO2, so that the NOX predicted by AERMOD is 100% NO2.
• Tier 2 – Ambient Ratio Method (ARM), where model predicted NOX concentrations are multiplied by a
NO2/NOX ambient ratio, derived from ambient monitoring data.
• Tier 3 – More detailed methods that account for the plume dispersion and chemistry may be considered
on a case-by-case basis, including the Ozone Limiting Method (OLM) and the Plume Volume Molar Ratio
Method (PVMRM).

For the NAAQS modeling of the Facility, a Tier 3 methodology utilizing OLM was used for the assessment of
NO2 impacts.
4.2 Background NO2 Concentrations
Background concentrations for NO2 for this modeling analysis were given by UDAQ from their Herriman
Monitoring station.4 The background data consists of design values calculated from data monitored from
2019-2021. The value used in the modeling analysis is the three-year average, high-third-high (H3H) of
seasonal 1-hour NO2 background. The background concentrations for NO2 are presented in Table 4-1 below.

4.4 Modeled NO2 Concentration
The resulting concentrations of 1-hour and annual NO2 from this air dispersion modeling analysis were
compared against the NO2 1-hour and annual NAAQS to demonstrate that emissions from the Facility do not
cause or contribute to an exceedance of the NO2 1-hour and annual NAAQS. The primary NAAQS is the
maximum concentration ceiling, measured in terms of total concentration of a pollutant in the atmosphere,
which is defined as the “level of air quality which the U.S. EPA judges are necessary, with an adequate
margin of safety, to protect the public health.”6 The 1-hour NO2 NAAQS requires the 8th highest
concentration over the five (5) modeled years to be compared to the standard. The annual NO2 NAAQS
requires that the 1st highest high concentration over the five (5) modeled years be compared to the
standard. The modeled concentration was added to the background concentrations for comparison to the
NAAQS. This calculation was completed based on results from the AERMOD modeling system.
4.5 NO2 NAAQS Analysis Results
A NAAQS analysis considers the impact from the sources at the Facility, nearby sources, and background
concentrations to yield a total concentration which is then compared to the NAAQS which, for 1-hour and 8-

hour NO2, is 188 and 100 µg/m3, respectively. Tables A-1 and A-2 in Appendix A present the model-
predicted concentrations from the Facility, nearby sources, and background concentrations for both the
primary and alternate engine options, according to the operating scenarios given in Section 3.1.2. These
concentrations are compared to the 1-hour and annual NO2 NAAQS.
In addition to this report, Aligned is providing the AERMOD Input and Output files for UDAQ’s review. These
will be submitted separately.
4.6 NO2 Mitsubishi Method Analysis Results
For the 1-hour NO2 modeling, the “Mitsubishi Method” was employed to demonstrate compliance at on-
property receptors for the following nearby facilities, located to the north, east, and south of the Facility:7
►ORACLE;
►SME;
►Novva;
►eBay;
►TJL; and
►DANONE.
Specifically, for one nearby facility at a time, Aligned’s data center and the other nearby facilities were
modeled to obtain total concentrations at receptors located on the property of the nearby facility in
question. For these models, the sources from the facility in question were turned off within the model (i.e.,
for this subset of receptors, a separate model was executed with all regional sources, excluding the sources
from the nearby facility in question). This process was completed for each modeling scenario and source
group listed in Section 3.1.2 of this report. The maximum modeled concentrations for both the primary and
alternate engine options, excluding all of each individual nearby facilities’ on-site receptors are provided in
Table A-1 and A-2 respectively. The maximum modeled concentrations including each nearby facilities’ on-
site receptors are provided in Table A-3 for reference.

EXECUTIVE SUMMARY
Aligned Data Centers (Aligned) is a company that specializes in the engineering, building, and operation of
data centers throughout the United States. Aligned is currently proposing to construct a new data center in West Jordan, Utah.

Aligned is submitting this Notice of Intent (NOI) air permit application to the Utah Division of Air Quality
(UDAQ) to obtain an air quality permit for their proposed West Jordan data center. The West Jordan data center will have emissions from one hundred ninety-two (192) emergency generators and one hundred
ninety-two (192) associated fuel storage tanks. These units will contribute to emissions of criteria pollutants,
namely particulate matter (PM) with an aerodynamic diameter of 10 microns or less (PM10), PM with an aerodynamic diameter of 2.5 or less (PM2.5), oxides of nitrogen (NOX), sulfur dioxide (SO2), carbon
monoxide (CO), and volatile organic compounds (VOCs). Hazardous air pollutant (HAP) and greenhouse gas
(GHG) emissions will also be generated. The proposed emergency generators’ operations are slated for periodic testing and maintenance not to exceed 100 hours per year under ordinary operating scenarios. If
local power is interrupted, the emergency engines will power the proposed West Jordan data center such
that there is no interruption in services to Aligned Data Center’s customers. Further description of this project has been included in Section 3 of this document. The maximum potential to emit (PTE) for the
proposed West Jordan data center is 0.81 tons per year (tpy) of PM10, 0.81 tpy of PM2.5, 24.34 tpy of NOx,
14.25 tpy of CO, 0.06 tpy of SO2, 0.71 tpy of VOCs, 0.16 tpy of total HAPs, and 5799.51 tpy of GHGs.

The facility is located within an area of Salt Lake County that is classified as in attainment for all pollutants
with exception to the following: (1) PM2.5 for which it is classified as a serious nonattainment area of the
National Ambient Air Quality Standards (NAAQS); (2) for the 2015 Ozone Standard, which is designated as
moderate nonattainment; and (3) a marginal nonattainment area of SO2. The PM10 nonattainment area was
redesignated as in attainment by the Environment Protection Agency (EPA) effective as of March 27, 2020.
The facility will be subject to New Source Performance Standards (NSPS) 40 Code of Federal Regulations
(CFR) 60 Subpart A (General Provisions), NSPS 40 CFR 60 Subpart IIII (Standards of Performance for
Stationary Compression Ignition Internal Combustion Engines), NSPS 63 Subpart A (General Provisions), and
NSPS 63 Subpart ZZZZ (National Emissions Standards for Hazardous Air Pollutants [NESHAP] for Stationary
Reciprocating Internal Combustion Engines).
This NOI air permit application has been developed pursuant to Utah Administrative Code (UAC) R307-401-5
and Utah’s application guidance, and includes, but is not limited to:

► NOI Air Permit Application Forms and Fees;
► Process Description;
► PTE Calculations;
► Best Available Control Technology (BACT) Analysis;
► Applicable Requirements; and
► Emission Impact Analysis.

DESCRIPTION OF PROJECT AND PROCESS
3.1 Description of Project
This proposed Aligned data center, located West Jordan, Utah, will house servers for Aligned’s clients. Air
emissions from the facility will result from the operation of emergency generators and storage tanks.

As standard with data centers that meet the requirements for Management and Operations Approved Sites,
Aligned’s West Jordan data center has been designed to have available backup power with N+1 capacity
providing at least 72-hour power outage protection. Additionally, this certification requires that West Jordan data
center maintains no more than 1.6 hours of downtime per year.
3.2 Description of Process
Aligned’s proposed West Jordan data center consists of a total of one hundred ninety-two (192) emergency
generators and one hundred ninety-two (192) associated diesel storage tanks to provide fuel for the generators
(the Project). Due to global supply chain and procurement issues surrounding emergency generators, Aligned is
proposing two (2) possible operation scenarios that will be dictated by engine availability at the time of purchase. Associated emissions for each scenario have been included in Appendix B of this document. Air dispersion
modeling has been performed on each of the proposed operation scenarios in order to demonstrate that the
“worst” impacting scenario will not cause or contribute to the NAAQS. Further information has been included in the modeling report packaged with this submittal.

Primary Operation Scenario
 One hundred eighty-two (182) Cat Model C175-16, 3,100 kW emergency generators;
» Each emergency generator is EPA Tier 2 certified and will utilize SCR control to reduce
emissions of NOx to Tier 4 standards;
» Each emergency generator will utilize only diesel fuel; and
» Each emergency generator will have an associated diesel tank for fuel storage.
 Ten (10) Cat C32 1,000 kW house emergency generators;
» Each emergency generator is EPA Tier 2 certified and will utilize SCR control to reduce
emissions of NOx to Tier 4 equivalent standards;
» Each emergency generator will utilize only diesel fuel; and
» Each emergency generator will have an associated diesel tank for fuel storage.

Alternate Operation Scenario
 One hundred eighty-two (182) Cat Model C3516E, 3,000 kW emergency generators;
» Each emergency generator is EPA Tier 2 certified and will utilize SCR control to reduce
emissions of NOx to Tier 4 standards;
» Each emergency generator will utilize only diesel fuel; and
» Each emergency generator will be associated with a diesel tank for fuel storage.
 Ten (10) Cat C32 1,000 kW house emergency generators;
» Each emergency generator is EPA Tier 2 certified and will utilize SCR control to reduce
emissions of NOx to Tier 4 equivalent standards;
» Each emergency generator will utilize only diesel fuel; and
» Each emergency generator will have an associated diesel tank for fuel storage.

The normal operation of Aligned’s emergency engines will be for periodic testing and maintenance only for a
maximum of 100 hours per calendar year.1 If local power is interrupted, the emergency engines will power the
West Jordan data center such that there is no interruption in services to Aligned’s customers; however, this
usage of the emergency engines is not considered “normal operation” as it only occurs in the event of an emergency event (e.g., a power outage). As such, the intended “normal” operation of periodic testing and
exercising events should be the basis of the calculation of the Project’s PTE.

EMISSIONS RELATED INFORMATION
This section details the methodology used to calculate controlled and uncontrolled emissions for criteria pollutants, greenhouse gases, and HAPs associated with each new unit and its associated fugitives as
regulated by R307-401-5(2)(b). Detailed emission calculation tables are included in Appendix B. Additionally,
a comparison to major source thresholds is conducted.
4.1 Diesel-Fired Emergency Generators
Emission calculations were performed for each of the proposed diesel-fired emergency generators with a
proposed cap on annual fuel usage of 511,945 gallons/year for testing and maintenance. Calculations for the criteria pollutants are based on the annual fuel usage at the maximum power output of each engine.
Each of the one hundred ninety-two (192) engines is EPA Tier 2 rated and will be installed with selective
catalytic reduction (SCR) add-on units. This will effectively alter the emissions output of each generator to be equivalent to EPA’s Tier 4-final standard for a generator set.2 PM, PM10, PM2.5, VOC, and CO PTE
emissions are calculated by multiplying the emission factors per manufacturer specification sheets by the
power output, annual fuel usage, and appropriate conversion factors, then dividing by the fuel consumption
per manufacturer specification sheets. Emission factors for PM10 and PM2.5 are conservatively assumed to be
equivalent to the emission factors for PM. PM10, PM2.5, VOC, and CO annual emission rates are calculated
using the following equation:
Annual Emission Rate (tpy)=Emission Factor �gramshp-hr�× Power Output [hp] Fuel Consumption�galhr�
× Conversion �0.0022 lbsgram�× Conversion �1 ton2,000 Ibs�× Annual Fuel Usage �galyr�

NOx emissions are calculated by multiplying the emission factors by the power output, annual fuel usage, emission reduction efficiency, and appropriate conversion factors. Emission factors were taken from
manufacturer specification sheets and emission reduction efficiency was taken from control technology
specifications. NOx annual emission rate is calculated using the following equation: Annual Emission Rate (tpy)=Emission Factor �gramshp-hr�× Power Output [hp] Fuel Consumption�galhr� ×
(1 −Control Efficiency)(%)× Annual Fuel Usage �galyr� × Conversion �0.0022 lbsgram�× Conversion �1 ton2,000 Ibs�

Annual and monthly testing of the one hundred ninety-two (192) diesel-fired emergency generators will be
conducted under varying loads. The modeling report included with this submittal will dictate the number of
engines that can be tested at a time. For the purposes of PTE calculations, the highest emissions from the various loads have been counted toward the site-wide PTE value. Therefore, the emissions calculations in

2 40 CFR 1039.101(b)

Aligned Data Centers (WJU) PropCo, LCC / NOI Air Permit Application Trinity Consultants 4-2
Appendix B show multiple loads, such that UDAQ may verify that the highest possible emissions rates have
been accounted for in the site-wide PTE value.
The engines at the West Jordan data center will be using ultra-low sulfur diesel (ULSD) fuel. The emission
factor for SO2 is based on a fuel sulfur content of 0.0015% for ultra-low sulfur diesel fuel, as defined under
40 CFR 80, Subpart I, Section 80.510(c)(1). The SO2 emission factor from AP-42 Section 3.4, Table 3.4-1
(10/96) is used in the emission calculations and accounts for the fuel sulfur content. SO2 annual emissions
are calculated using the following equation.
SO2 Annual Emission Rate (tpy)=Emission Factor �lbhp-hr�× Power Output [hp]Fuel Consumption �galhr�× Conversion �1 ton2,000 Ibs�
× Annual Fuel Usage �galyr�

GHG pollutants expected to be emitted from the emergency generators include carbon dioxide (CO2),
methane (CH4), and nitrous oxide (N2O). Standard emission factors for CO2, CH4, and N2O are provided in
40 CFR Part 98, Subpart C, Table C-1, and Table C-2. The global warming potential for each relevant
pollutant is obtained from 40 CFR Part 98, Subpart A, Table A-1. Calculations for GHG pollutants are based
on the emission factor for each GHG pollutant, relevant global warming potential, annual fuel usage, and
relevant conversion factors.
Carbon Dioxide Equivalent (CO2e) Annual Emission Rate �tonsyr�=�Emission Factor CO2 �lbgal�+Emission Factor CH4 �lbgal�× GWP CH4+Emission Factor N2O �lbgal�× GWP N2O�×Annual Fuel Usage �galyr�× �1 ton2000 lb�

HAP emissions are determined using the maximum heat input and annual fuel usage. Emission factors for
HAPs are obtained from AP-42, Section 3.4, Tables 3.4-3 and 3.4-4. To be conservative, HAP emissions are
calculated for all speciated organic compounds and polycyclic aromatic hydrocarbons (PAH), provided in AP-
42, Section 3.4, Tables 3.4-3 and 3.4-4.
Manufacturer specification sheets for the emergency generators can be found in Appendix C.
4.2 Storage Tanks
The Project includes one hundred ninety-two (192) belly tanks associated with each corresponding diesel
engine. Each generator set has a belly tank situated underneath each engine. Emissions for each tank were
calculated per AP-42, Section 7.1 (Organic Liquid Storage Tanks). Specifically, equations contained in
Section 7.1.3.1 (Total Losses from Fixed Roof Tanks) are utilized.

Emission from the belly tanks include VOCs and HAPs and are dependent on fuel throughput, which is
equivalent to the proposed site wide fuel limit of the generators. A safety factor of two (2) was applied to
the emissions, resulting in a conservative estimate of tank emissions.

Aligned Data Centers (WJU) PropCo, LCC / NOI Air Permit Application Trinity Consultants 4-3
VOC Emissions
Emissions for each belly tank were calculated per AP-42, Section 5.2: Transportation and Marketing of
Petroleum Liquids. Specifically, equations contained in Section 5.2.2.1.1 (Loading Losses) are utilized.
LL �lb103gal�=12.46 SPMT �1 −eff100�(SF)
LL = loading loss S = saturation factor for “splash loading: dedicated normal service” (Table 5.2-1)
P = true vapor pressure of diesel (Table 7.1-2)
M = molecular weight of gasoline vapors (Table 7.1-2) T = temperature of diesel
eff = overall reduction efficiency
SF = safety factor of two (2)
The loading loss was then multiplied by the belly tank diesel throughput in the following equation:
VOC Annual Emission Rate (tpy)=LL �lb103gal�× Diesel Usage�galyr�× Conversion �103 gal1,000 gal�× Conversion �1 ton2,000 lbs�
HAP Emissions
HAP emissions from the belly tank were based on vapor weight percents of diesel fuel from TankESP. The weight percents were multiplied by the VOC loading loss as seen in the following equation:
HAP Annual Emission Rate (tpy)=VOC Annual Emission Rate (tpy)× HAP wt %

BEST AVAILABLE CONTROL TECHNOLOGY (BACT) ANALYSIS
In the State of Utah, under R307-401-5(2)(d), Notice of Intent, every facility, operation, or process that
proposes any activity that would emit an air contaminant into the air, must consider best available control technology (BACT) for a proposed new source or modification.3 The below BACT analysis addresses all units
installed, or otherwise addressed in this NOI air permit application.
5.1 Emergency Diesel-Fired Engines – BACT Analysis
5.1.1 PM2.5, NOx, SO2 and VOC Emergency Diesel-Fired Engines Step 1 – Identify All Control Technologies
The following sources were reviewed to identify available control technologies: 1. EPA’s RBLC Database for Diesel Generators (process type 17.110 Large Internal Combustion Engines
[>500 Hp] – Fuel Oil);4 2. EPA’s Air Pollution Technology Fact Sheets; and 3. South Coast Air Quality Management District Example Permits.
Available control technologies for diesel-fired emergency engines include the following:
• Limited Hours of Operation;
• Good Combustion Practices;
• Use of a Tier Certified Engine;
• Engine Design;
• Diesel Particulate Filter;
• Ultra-Low Sulfur Fuel;
• Diesel Oxidation Catalyst (DOC);
• Exhaust Gas Recirculation (EGR); and
• Selective Catalyst Reduction (SCR).
5.1.2 PM2.5, NOx, SO2 and VOC Emergency Diesel-Fired Engines Step 2 –
Eliminate Technically Infeasible Options
Limited Hours of Operation
One of the apparent opportunities to control the emissions of all pollutants released from emergency
engines is to limit the hours of operation for the equipment. Due to the designation of the proposed
equipment as emergency equipment, only 100 hours of operation for maintenance and testing are permitted
per NSPS Subpart IIII.5
Good Combustion Practices
Good combustion practices refer to the operation of engines at high combustion efficiency, which reduces
the products of incomplete combustion. The emergency engines proposed for this project are designed to

4 Database accessed October 1, 2021. 5 40 CFR 60.4211(f)(2)

Aligned Data Centers (WJU) PropCo, LCC / NOI Air Permit Application Trinity Consultants 5-2
achieve maximum combustion efficiency. The manufacturer has provided operation and maintenance
manuals that detail the required methods to achieve the highest levels of combustion efficiency.
Use of an Appropriate Tier Certified Engines
EPA noted that non-road engines were a significant source of emissions and began adopting emission
standards for these emission units in 1994. Today, engines are required to meet certain emission limits, or
tier ratings, based on the size and model year. Emission standards for these engines have progressively
become more stringent over time and are an indicator of good combustion design. Aligned proposes to
install engines with an EPA Tier rating available at the time of purchase. The engines purchased for the
Facility are EPA Tier 2 rated. However, with the addition of an SCR add-on unit, the proposed EPA Tier 2
rated engines meet the standards of that rated as EPA Tier 4-final. This will be discussed more in depth in
the following sections.
Diesel Particulate Filters
This technology is placed in the exhaust pathway to prevent the release of particulate and may be coated
with a catalyst to further capture hydrocarbon emissions.

According to EPA’s Response to Public Comments on Notice of Reconsideration of NESHAP for RICE and
NSPS for Stationary ICE, “Diesel particulate filters are also proven, commercially available technology for
retrofit applications to stationary engines…and are capable of reducing diesel PM by 90 percent or more.”6
Additionally, the California Air Resources Board (CARB) was able to determine that this technology was
technically feasible for emergency and prime engines through obtaining several vendor quotes. 7 However,
EPA remained concerned with the installation of a catalyzed particulate filter, citing technical issues,
including the fact that many older engines are not electronically controlled, that PM emissions are often too
high for efficient operation, and, in some cases, engine exhaust temperatures are not high enough for filter
substrate regeneration.8

While a catalytic diesel particulate filter is not considered to be technically feasible, consideration of a simple
particulate filter will be evaluated.
Ultra-Low Sulfur Diesel
ULSD contains less than 0.0015% sulfur by weight. The reduced sulfur content reduces the potential for SO2
emissions. Additionally, the low sulfur content results in a lower potential for aggregation of sulfur-
containing compounds and thus reduces PM2.5 emissions. Aligned will use ULSD fuel for the proposed diesel-
fired emergency engines on-site.

Diesel Oxidation Catalyst
DOC utilizes a catalyst such as platinum or palladium to oxidize the engine’s exhaust, which includes
hydrocarbons (HC), (e.g., VOC), to CO2 and water. Use of a DOC can result in approximately 90% reduction
in HC/VOC emissions.9 In addition to controlling HC/VOC, a DOC also has the potential to reduce PM
emissions by 30% (based on the concentration of soluble organics) and CO emissions by 50% if low sulfur
diesel fuel is used.10 The use of a DOC reduces the effective power output of RICE and results in a solid
waste stream. However, for the purposes of identifying technical feasibility, no formal consideration of these
adverse energy and environmental impacts is presented. A DOC is considered technically infeasible due to
the reduction in power.

Exhaust Gas Recirculation

NOX reduction can be achieved through recirculating exhaust into the engine. EPA tests have demonstrated
NOX reduction up to 50% if the engine timing is retarded, but test results are accompanied by an increase in particulates11. Computer based control schemes can assist in NOX reduction with associated timing
retardation, but EGR can also result in heat rejection, reduced power density and lower fuel economy. As a
result, EGR is technically infeasible.
Selective Catalytic Reduction
SCR systems introduce a liquid reducing agent such as ammonia or urea into the flue gas stream prior to a
catalyst. The catalyst reduces the temperature needed to initiate the reaction between the reducing agent
and NOX to form nitrogen and water.

For SCR systems to function effectively, exhaust temperatures must be high enough (200°C to 500°C) to
enable catalyst activation. Since the proposed generators operate above these temperatures, SCR is
feasible.

5.1.3 PM2.5, NOX, SO2 and VOC Emergency Diesel-Fired Engines Step 3 – Rank Remaining Control Technologies by Control Effectiveness
Effective control technologies for diesel engines include limited hours of operation, good combustion
practices, use of tier-certified engines, use of high efficiency engines, use of diesel particulate filters, use of
DOC, and combustion of ULSD. All control technologies considered effective are currently implemented for
the proposed emergency engines with the exception of diesel particulate filters and DOCs. Both technologies
result in significant emission reductions and are further evaluated to determine the economic feasibility of
implementation in Step 4. NOX emission reductions are achieved through SCR add-on units, which meet
EPA’s Tier 4-final rating.

5.1.4 PM2.5, NOX, SO2 and VOC Emergency Diesel-Fired Engines Step 4 –
Evaluate Most-Effective Controls and Document Results
When reviewing the implementation and costs associated with installing DOC controls for an emergency-use
or intermittent-use engine, Aligned found that “[b]ecause these engines are typically used only a few
number of hours per year…[s]uch engines rarely if ever use the [diesel oxidation catalyst] type of emission
controls.”12 Additionally, in its 2010 Maximum Achievable Control Technology (MACT)/ Generally Available
Control Technology (GACT) evaluation for engines, EPA concluded for emergency engines: “Because these
engines are typically used only a few number of hours per year [(27 hours per year per NFPA codes)], the
costs of emission control are not warranted when compared to the emission reductions that would be
achieved.”13 Based on EPA’s assessment and the fact that the RBLC contains no records of DOC installation
on emergency-use or non-road engines, installation of a DOC unit is eliminated from consideration as BACT.

EPA gathered cost estimates for installing a diesel particulate filter when reviewing NESHAP ZZZZ and NSPS
IIII and JJJJ, and determined the costs to be excessive.14 EPA determined that the cost per ton of PM
reduced from engines between 300 and 600 HP was close to $260,000 and more than $700,000 for engines
above 750 HP when installed at the time of manufacturing.15 EPA concluded that the installation of a diesel
particulate filter was only required for the operation of non-emergency engines as documented in NESHAP
Subpart ZZZZ; therefore, this technology is not further considered.16
PM2.5, NOx, SO2 and VOC Emergency Diesel-Fired Engines Step 5 – Select
BACT
The diesel-fired emergency engines proposed for the Facility are well designed, efficient, reliable, and will
be operated using good combustion practices. The diesel-fired engines installed after the implementation of
the EPA’s Tier system meet the required Tier rating in 40 CFR 89 based on available inventory at the time of
purchase. The selected engines use SCR to meet Tier 4-final standards. Additionally, the emergency engines
will be operated and maintained in accordance with good combustion practices and combust only ULSD. The
hours of operation are restricted to 100 hours per year under non-emergency circumstances for
maintenance and testing in accordance with 40 CFR 60, Subpart IIII. As a result, the diesel-fired emergency
engines are considered to meet BACT.

5.1 Diesel Tanks – BACT Analysis
Aligned is proposing to permit one hundred ninety-two (192) diesel tanks that will have a total annual
throughput equivalent to the fuel usage limit of 511,945 gallons. The combined potential to emit from the
diesel tanks is 1.38E-02 tpy of VOCs and 9.20E-03 tpy of total HAPs.
Diesel Tanks VOCs & Volatile HAPs - Steps 1-5

Emissions from fixed-roof storage tanks result from displacement of headspace vapor during filling
operations (working losses) and from diurnal temperature and heating variations (breathing losses). While a variety of technologies may be considered, due to the size and minimal throughput anticipated for the
proposed tanks, VOC emissions from the tanks are minimal, as demonstrated in the emission calculations.
Each belly tank stands at a shallow 30 inches high, meaning that splashing will be minimized during filling operations, as the distance that the fuel falls from the feed to the surface of the fuel oil in each tank is
minimal. Per AP-42 5.2, Transportation and Marketing of Petroleum Liquids, higher levels of turbulence
during splash loading results in increased amounts of vapor generation and loss. Because of the shallow nature of the belly tanks, turbulence during filling operations will be minimized, thus reducing emissions,
especially compared to standard horizontal fixed-roof or vertical fixed-roof tanks.
Because of these various considerations – namely, low throughput, shallow depth, reduced splashing, and
the involatile nature of No. 2 fuel oil – emissions from these belly tanks are minimal, and BACT is considered
the use of best management and operational practices.

EMISSION IMPACT ANALYSIS
Appendix Table B-1 compares criteria pollutant maximum proposed emissions to applicable modeling
thresholds contained in R307-403-4 through 7, and R307-410-4. Due to the uncertainty with the emergency generators that will be used, the units with the highest emissions rates are used for this analysis to
represent the worst-case scenario when it comes to emissions.
Although modeling limits have not been surpassed, an air dispersion modeling analysis that demonstrates
the impacts of the site-wide criteria pollutant emissions from the proposed changes has been prepared and
will be presented to UDAQ with this submittal in a separate document.

Aligned Data Centers (WJU) PropCo, LCC / NOI Air Permit Application Trinity Consultants 7-1
NONATTAINMENT/MAINTENANCE AREAS - OFFSETTING
7.1 Offset Applicability
PM2.5 Offsets
PM2.5 offsets are required for sources located in serious nonattainment areas that are a major source of
PM2.5 (i.e., 70 tpy of direct PM2.5 or individual PM2.5 precursors) or have a major modification of an existing
source with an emissions increase greater than 10 tpy of direct PM2.5, 40 tpy of sulfur dioxide, 40 tpy of
nitrogen oxides, or 40 tpy of VOC. 17 The proposed project does not exceed major-source thresholds for
PM2.5 or any of its precursors (as shown in Appendix Table B-1); therefore, PM2.5 offsets are not required for
the West Jordan data center.
PM10 Offsets
PM10 offsets requirements are described in UAC R307-421-2. They apply to new or modified sources that are
located in, or impact, Salt Lake County or Utah County and increase SO2 or NOX by 25 tpy or more. 18 The
proposed data center is located in Salt Lake County but is proposing emissions of SO2 and NOX below the 25
tpy limit. The West Jordan data center is therefore not subject to the PM10 offset requirements of R307-421.
Ozone Offsets
Ozone offsets requirements recorded in UAC R307-420-3(2) and VOC offsets are applicable to significant
sources located within or impacting an ozone nonattainment area of the NAAQS. In summary, significant
sources located in Davis County or Salt Lake County shall offset the proposed increase in VOC emissions by
a ratio of 1.2:1 before the Director may issue an approval order to construct, modify, or relocate under
R307-401.

Furthermore, "significant" means, for the purposes of determining what is a significant emission increase or a
significant net emission increase and therefore a major modification, a rate of emissions that would equal or
exceed any of the following rates: 19
(1) for volatile organic compounds, 25 tons per year,
(2) for nitrogen oxides, 40 tons per year.

The proposed PTE of the West Jordan data center presented in Appendix B is less than 25 tpy of VOCs and
less than 40 tpy of nitrogen oxides, rendering ozone offsets inapplicable to the plant.

1. The subject rule is or could be applicable to the Aligned data center; however, this rule is not specific to operational
compliance requirements and is therefore not discussed in this NOI air permit application. 2. At the time of submission of this NOI air permit application, this rule does not apply.
UAC R307-101 General Requirements
Chapter 19-2 and the rules adopted by the Air Quality Board constitute the basis for control of air pollution
sources in the state. These rules apply and will be enforced throughout the state and are recommended for
adoption in local jurisdictions where environmental specialists are available to cooperate in implementing rule
requirements.

NAAQS, NSPS, National Prevention of Significant Deterioration of Air Quality (PSD) standards, and the NESHAP
apply throughout the nation and are legally enforceable in Utah.

Aligned will comply and conform to the definitions, terms, abbreviations, and references used in the R307-
101 and 40 CFR.
UAC R307-107 General Requirements: Breakdowns
Aligned will report breakdowns at the Facility within 24 hours via telephone, electronic mail, fax, or other
similar method and provide detailed written description within 14 days of the onset of the incident to UDAQ.

Aligned Data Centers (WJU) PropCo, LCC / NOI Air Permit Application Trinity Consultants 8-5
Breakdown reports will include all reporting details outlined in R307-107-2, including, but not limited to, the
cause and nature of the event, estimated quantity of emissions, and time of emissions.
UAC R307-150 Emission Inventories
For every third year, Aligned will report its emissions inventory in accordance with R307-150-6. The
emissions inventory shall include all criteria pollutants, including filterable and condensable PM, hazardous
air pollutants not exempted in R307-150-8 and chargeable pollutants in accordance with R307-150-6.
UAC R307-201 Emission Standards: General Emission Standards
All rules applicable to Aligned are incorporated by reference from 40 CFR Part 60. Applicability and
requirements for these rules are outlined in Section 8.2 of this submittal.
UAC R307-203 Emission Standards: Sulfur Content of Fuels
Sulfur emissions shall be no more than 0.85 pounds sulfur per million gross BTU heat input for any oil. The
following specifications for each purchase of fuel oil are recorded: weight percent sulfur, gross heating value
(Btu per unit volume), and density. These parameters shall be determined in accordance with the methods
of the American Society for Testing and Materials (ASTM). Records of fuel sulfur content shall be kept for all
periods when the plant is in operation and shall be made available to the Director upon request and shall include a period of two years ending with the date of the request.
Aligned will record the following specifications for each purchase of fuel oil in the event that it will be used:
weight percent sulfur, gross heating value (Btu per unit volume), and density. In doing so, Aligned will meet the emission standards for sulfur content of fuel as described in R307-203)(1)(a).
UAC R307-305 Nonattainment and Maintenance Areas for PM10: Emission
Standards
Emissions from diesel engines, except locomotives, shall be of a shade or density no darker than 20%
opacity, except for starting motion no farther than 100 yards or for stationary operation not exceeding three
minutes in any hour. Visible emissions shall be measured using EPA Method 9.
Visible emissions exceeding the opacity standards for short time periods as the result of initial warm-up,
soot blowing, cleaning of grates, building of boiler fires, cooling, etc., caused by start-up or shutdown of a facility, installation or operation, or unavoidable combustion irregularities which do not exceed three minutes
in length are not to be deemed in violation provided that the director finds that adequate control technology
has been applied. The owner or operator shall minimize visible and non-visible emissions during start-up or shutdown of a facility, installation, or operation through the use of adequate control technology and proper
procedures.
UAC R307-325 Ozone Nonattainment and Maintenance Areas: General
Requirements
The Facility is located in the Northern Wasatch Front Ozone Nonattainment area and produces VOCs as part of its operations. This rule is therefore applicable. Aligned will ensure that VOCs are not spilled, discarded,
stored in open containers, or handled in any other manner that would result in greater evaporation of VOCs
than would have if reasonably available control technology (RACT) had been applied.

Aligned Data Centers (WJU) PropCo, LCC / NOI Air Permit Application Trinity Consultants 8-6
UAC R307-410-8 Permits: Permit New and Modified Sources – Approval
Order
(1) The director will issue an AO if all conditions and regulations have been met.
(a) The degree of pollution control for emissions, to include fugitive emissions and fugitive dust, is at least best available control technology. When determining best available control technology for a
new or modified source in an ozone nonattainment or maintenance area that will emit VOCs or NOX,
best available control technology shall be at least as stringent as any Control Technique Guidance document that has been published by EPA that is applicable to the source.
(b) The proposed installation will meet the applicable requirements of:
(i) R307-403, Permits: New and Modified Sources in Nonattainment Areas and Maintenance

provisions of R307 or the State Implementation Plan.

BACT provisions specified in UAC R307-401 have been applied through control equipment installed and
monitoring conditions.

The Facility will comply with all applicable requirements detailed above.
UAC R307-414 Permits: Fees for Approval Orders
Fees associated with the submission of this NOI air permit application are addressed in Section 2 of this
submittal.
8.2 Federal Rules: National Emission Standards for Hazardous Air
Pollutants
The NESHAP federal regulations found in Title 40 Part 61 and 63 of the CFR are emission standards for
HAPs. NESHAP are applicable to both major sources of HAPs (facilities that exceed the major source
thresholds of 10 tpy of a single HAP and 25 tpy of any combination of HAPs from stationary sources) as well as non-major sources (termed “minor sources”). NESHAP applies to sources in specifically regulated
industrial source classifications (Clean Air Act Section 112(d)) or on a case-by-case basis (Clean Air Act
Section 112(g)) for facilities not regulated as a specific industrial source type.
The Facility is a minor source under the NSR program. As such, this document only addresses regulatory
applicability for area sources and does not include standards for major sources.

Aligned Data Centers (WJU) PropCo, LCC / NOI Air Permit Application Trinity Consultants 8-7
Subpart A – General Provisions
NESHAP Subpart A, General Provisions, contains national emissions standards for HAPs defined in Section
112(b) of the Clean Air Act. All affected sources, which are subject to another NESHAP are subject to the
general provisions of NESHAP Subpart A, unless specifically excluded by the source specific NEHSAP.
Subpart A requires initial notification, performance testing, recordkeeping, and monitoring, provides
reference methods, and mandates general control device requirements for all other subparts. The following
sections detailing each subpart requirements also include requirements that are referenced to Subpart A.

8.2.2 Subpart ZZZZ – Stationary Reciprocating Internal Combustion Engines
NESHAP Subpart ZZZZ, National Emission Standards for Hazardous Air Pollutants for Stationary
Reciprocating Internal Combustion Engines, applies to stationary reciprocating internal combustion engines
(RICE) at major and area sources of HAPs. Per 40 CFR 63.6590(a)(2)(iii), a stationary RICE at an area
source of HAPs is new if construction commenced after June 12, 2006. Thus, the proposed engines are
considered a new stationary RICE under NESHAP Subpart ZZZZ. Per 40 CFR 63.6590(c) and 40 CFR
63.6590(c)(1), new stationary RICE located at an area source of HAP may show compliance with NESHAP
ZZZZ by being in compliance with NSPS IIII.20 The Facility is not a major source of HAPs, as total HAP
emissions amount to less than 10 tons per year for an individual HAP and less than 25 tons per year of total
HAPs. By maintaining compliance with NSPS IIII, Aligned can demonstrate compliance with NESHAP ZZZZ.
8.3 Federal Rules: New Source Performance Standards
NSPS requires new, modified, or reconstructed sources to control emissions to the level achievable by the
best demonstrated technology as specified in the applicable provisions. Moreover, any source subject to
NSPS is also subject to the general provisions of NSPS Subpart A, except as noted. The following section details the applicability of NSPS regulations to the West Jordan data center operations.
Subpart A – General Provisions
All affected sources subject to source-specific NSPS are subject to the general provisions of NSPS Subpart A
unless specifically excluded by the source-specific NSPS. Subpart A requires initial notification, performance
testing, recordkeeping, and monitoring, provides reference methods, and mandates general control device
requirements for all other subparts.
NSPS Subpart IIII – Standards of Performance for Stationary Compression
Ignition Internal Combustion Engines
NSPS Subpart IIII, Standards of Performance for Stationary Compression Ignition Internal Combustion
Engines, establishes requirements for stationary compression ignition internal combustion engines for which construction, modification, or reconstruction commenced after July 11, 2005.

The provisions of this subpart are applicable to owners and operators of compression ignition internal combustion engines which commenced construction after July 11, 2005, and they were manufactured after
April 1, 2006. The construction date is the date the engine was intended to be ordered by the owner or
operator. The engines powering the proposed generators listed in Section 3.2 were constructed or are intended to be constructed after the specified construction dates. NSPS IIII is applicable to these engines.

20 NESHAP Subpart 40 CFR 63.6675

Aligned Data Centers (WJU) PropCo, LCC / NOI Air Permit Application Trinity Consultants 8-8
Emission Limitation
Emergency stationary CI ICE with a displacement of < 10 liters per cylinder that are not fire pump engines
must comply with the emission standards for new nonroad CI engines in §60.4202(a), for all pollutants, for
the same model year and maximum engine power for their 2007 model year and later emergency stationary
CI ICE.21 These limitations must be met for the life of the engine.22
Fuel Requirements
Owners and operators of stationary CI ICE subject to this subpart with a displacement of less than 30 liters
per cylinder that use diesel fuel must use diesel fuel that meets the requirements of 40 CFR 80.510(b) for
nonroad diesel fuel, except that any existing diesel fuel purchased (or otherwise obtained) prior to October
1, 2010, may be used until depleted.23
The requirements of 40 CFR 80.510(b) are as follows: 1) 15 ppm sulfur, and
2) minimum cetane index of 40 or maximum aromatic content of 35 volume percent.
Monitoring Requirements
Each CI ICE that does not meet the standards applicable to non-emergency engines, must install a non-
resettable hour meter prior to startup of the engine.24 Each CI ICE equipped with a diesel particulate filter
to comply with the emission standards in §60.4204, the diesel particulate filter must be installed with a
backpressure monitor that notifies the owner or operator when the high backpressure limit of the engine is
approached.25
Compliance Requirements
• Operate, maintain, install, and configure the stationary CI internal combustion engine and
control device according to the manufacturer's emission-related written instructions;26
• Change only those emission-related settings that are permitted by the manufacturer; 27
• Meet the requirements of 40 CFR 89, 94, and/or 1068;28
• Stationary CI internal combustion engine must comply with the emission standards specified in
§60.4204(b) or §60.4205(b).29
Emergency Engine30
The engine may be operated for 100 hours per calendar year for maintenance checks, readiness testing,
periods where there is a deviation of voltage or frequency of 5 percent or greater below standard voltage or
frequency, and/or up to 50 hours per calendar year in non-emergency situations. There is no limit for
emergency usage of the engine in emergency situations.

Aligned Data Centers (WJU) PropCo, LCC / NOI Air Permit Application Trinity Consultants 8-9
Recordkeeping31
Using the non-resettable hour meter, a record of the engine's emergency operation must be kept. The
records must contain the time of operation and the reason the engine was in operation.
Aligned also retains records to indicate that the engine is certified to the emission standards required for the
appropriate manufacture year and size.32
NSPS Subpart Kb – Storage Tanks
NSPS, Subpart Kb, Standards of Performance for Volatile Organic Liquid Storage Vessels, regulates storage vessels with a design capacity greater than or equal to 75 cubic meters (m3) that store volatile organic
liquids.33 The standards are effective for all facilities for which construction, reconstruction, or modification
commenced after July 23, 1984. Storage vessels with a capacity greater than or equal to 151 cubic meters (m3) storing a liquid with a maximum true vapor pressure, excluding water, less than 3.5 kilopascals (kPa)
or with a capacity greater than or equal to 75 m3 but less than 151 m3 storing a liquid with a maximum true
vapor pressure less than 15.0 kPa are exempt from the requirements of this rule.34 Tanks that are subject to this rule must be equipped with sealing systems or closed vent systems and are subject to recordkeeping
and reporting requirements.35
All proposed storage tanks at the Facility are less than 75 m3 in volume. NSPS Subpart Kb is therefore not
applicable to the facility.
