SOURCE INFORMATION
General Description
Tesoro Logistics Operations LLC (TLO) operates a Remote Tank Farm (RTF) and Truck Loading Rack
(TLR). The TLR is located on property adjacent to and south of the Tesoro Refinery, but is fenced and
monitored so that authorized access is controlled independently from the refinery. The RTF is located
approximately 1 mile northwest of the Tesoro Refinery.

The TLR is a fuel-loading facility for distribution of products produced by the Tesoro Salt Lake City
Refinery. The facility includes five truck transport load spots, each capable of delivering gasoline, jet
fuel, and distillate products to tank trucks. Ethanol and other additives are blended in line with refined
products during transfer to trucks. Runoff from the loading bays is routed through a catch basin and then
to the oil-water separator (OWS). Oil separated from the runoff is routed from the OWS to the refinery's
slop oil system, and the water phase is routed to the refinery's oily water sewer. A crude oil unloading
facility is also operated at the TLR. Crude oil is unloaded from tank trucks and transferred directly to the
refinery; there is no storage of crude oil at the TLR.

The RTF receives crude oil via pipeline, which is stored in storage tanks before being sent to the Tesoro
Refinery crude unit. The RTF also has bidirectional pipelines from the refinery and storage tanks, which
are used to supplement gasoline and diesel storage capacity at the Tesoro Refinery. In addition, gasoline
and diesel products are distributed to transportation pipelines from the RTF.

Project Description
TLO submitted an NOI for the approval of a denatured ethanol storage tank. The tank (Tank 509) is
currently an out-of-service tank located at the Salt Lake City TLR. TLO is a subsidiary of Marathon
Petroleum Corporation (Marathon). This project does not involve Tesoro Refining & Marketing Company
LLC's Salt Lake City Refinery, which is also a fully owned subsidiary of Marathon. Tank 509 will be
retrofitted with an internal floating roof to control emissions from denatured ethanol storage. TLO has
evaluated the project impacts to other portions of the terminal and refinery, and has determined that no
other emission units are affected by the project. This project will not result in additional gasoline products
being loaded at TLR. As the total expected emission increase from the project is approximately 1 tpy of
VOC, this is a minor modification.

SUMMARY OF EMISSIONS

The emissions listed below are an estimate of the total potential emissions from the source. Some
rounding of emissions is possible.

SOURCE DESCRIPTION General Description
Tesoro Logistics Operations LLC (TLO) operates a Remote Tank Farm (RTF) and Truck Loading Rack (TLR). The TLR is located on property adjacent to and south of the Tesoro Refinery, but is fenced and monitored so that authorized access is controlled independent from
the refinery. The RTF is located approximately 1 mile northwest of the Tesoro Refinery. The TLR is a fuel-loading facility for distribution of products produced by the Tesoro Salt Lake
City Refinery. The facility includes five truck transport load spots each capable of delivering gasoline, jet fuel, and distillate products to tank trucks. Ethanol and other additives are blended in line with refined products during transfer to trucks. Runoff from the loading bays is routed
through a catch basin and then to the oil-water separator (OWS). Oil separated from the runoff is routed from the OWS to the refinery's slop oil system, and the water phase is routed to the refinery's oily water sewer. A crude oil unloading facility is also operated at the TLR. Crude oil is
unloaded from tank trucks and transferred directly to the refinery - there is no storage of crude oil at the TLR. The RTF receives crude oil via pipeline, which is stored in storage tanks before being sent to the Tesoro Refinery crude unit. The RTF also has bidirectional pipelines from the refinery and storage tanks which are used to supplement gasoline and diesel storage capacity at the Tesoro Refinery. In addition, gasoline and diesel products are distributed to transportation pipelines from the RTF.

Modification to Approval Order DAQE-AN156590009-23 For the Refurbishing of Tank 509 Project Description
TLO submitted an NOI for the approval of a denatured ethanol storage tank. The tank (Tank 509) is currently an out of service tank located at the Salt Lake City Truck Loading Rack (TLR). TLO is a subsidiary of Marathon Petroleum Corporation (Marathon). This project does not involve Tesoro Refining & Marketing Company LLC's Salt Lake City Refinery, which is also a fully owned subsidiary of Marathon. Tank 509 will be retrofitted with an internal floating roof to control emissions from denatured ethanol storage. TLO has evaluated the Project impacts to other portions of the terminal and refinery, and has determined that no other emission units are affected by the Project. This project will not result in additional gasoline products being loaded at TLR.
As the total expected emission increase from the project is approximately 1 tpy of VOC, this is a minor modification. EMISSION IMPACT ANALYSIS The total increase in emissions from this project is 1.01 tpy of VOC. This value does not trigger modeling under R307-410-4. Although ethanol is not considered a HAP, it is assumed that denatured ethanol contains 5% gasoline. Therefore, a small amount of HAP emissions exist - although this total is less than 0.002 tpy (approximately 4 lbs per year of BTEX and related species). The expected emissions do not qualify for an in-depth analysis under R307-410-5. Therefore, no modeling is required. [Last updated August 14, 2024]

Review of BACT for New/Modified Emission Units 1. BACT review regarding BACT for VOCs from Tank 509 and fugitive emissions from
components in VOC service There are two potential sources of VOC emissions from this project: Tank 509 and new components in VOC service (specifically the piping and connectors associated with the tank). The
tank will be outfitted with an internal floating roof, which meets the requirements under both NSPS Subpart Kb and MACT Subpart CC. Thermal oxidation (TO) was evaluated for control of the VOC emissions from the tank. This option was determined to be economically infeasible given
the small amount of VOCs being controlled and the significant amount of natural gas required to meet the minimum temperature requirements of the TO. For control of fugitive VOCs from the miscellaneous components in VOC service, TLO has suggested that these components be subject to the enhance leak detection and repair (LDAR)
requirements of NSPS Subpart GGGa, which are already required at the facility. No other control option for reducing fugitive VOC emissions from this type of equipment/operation has been shown more effective.
The NSR section agrees that the use of enhanced LDAR and the addition of an internal floating roof represent BACT for this project. [Last updated August 14, 2024]

REVIEWER COMMENTS

1. Comment regarding Federal Subparts: NSPS: The physical changes performed as part of the project affect storage tanks by refurbishing and
retrofitting Tank 509. Additionally, new fugitive components in VOC service will be installed. Applicability of these changes to 40 CFR 60 Subparts Kb, Kc, and GGGa are discussed below in additional detail. Regulatory coverage for other NSPS subparts currently applicable to the facility are
as follows: 40 CFR 60 Subparts A, XX and QQQ. These are listed in Section III of the AO and will not change as a result of this project. Subpart Kb: The refurbished Tank 509 will experience an increase in the maximum hourly emission rate as a result of storing materials of a higher vapor pressure than current operations. Thus, this
project qualifies as a modification under 40 CFR 60 Subpart A. Tank 509 is subject to Subpart Kb. Subpart Kc: Subpart Kc is a proposed rule regulating volatile organic liquid storage vessels. If the proposed rule is finalized as currently proposed, Tank 509 will undergo a "modification" when refurbished for service and become subject to Subpart Kc in lieu of Subpart Kb. The tank would then
meet the specifications of Subpart Kc and be subject to the corresponding monitoring, recordkeeping, and reporting requirements. Subpart GGGa: Subpart GGGa regulates equipment leaks from the group of all the equipment in VOC service within a process unit that are constructed, reconstructed, or modified after November 7, 2006 at a petroleum refinery. TLO is already subject to 40 CFR 60 Subpart GGGa for equipment leaks. New and replaced components added as part of the Project are subject to Subpart GGGa. NESHAP/MACT: NESHAP standards from 40 CFR 61 and 40 CFR 63 are incorporated by reference into the UDAQ rules. TLO is currently subject to 40 CFR 63 Subpart CC for "National Emission Standards for
Hazardous Air Pollutants from Petroleum Refineries" because the TLO facility is considered part of the same stationary source as the refinery. Storage vessels and equipment leaks are regulated as emission points under this subpart, so the new tank and components associated with this project will be subject to Subpart CC. TLO will continue to comply with the emission standards and other requirements of this rule. TLO will comply with Subpart CC for the tanks by either (1) complying with NSPS Subpart Kb if not subject to NSPS Subpart Kc, or (2) complying directly with the requirements of Subpart CC, which incorporates requirements under Subpart WW. No new requirements will be triggered as a result of this Project.
Regulatory coverage for other subparts currently applicable to the facility (40 CFR 61 Subparts A, M, and FF and 40 CFR 63 Subpart EEEE as listed in Section III of the AO) will not change as a
result of this project [Last updated August 14, 2024]

Engineer Review N156590010: Tesoro Logistics Operations LLC - Truck Loading Rack and Remote Tank Farm August 21, 2024 Page 12
2. Comment regarding Emission calculations: Emission for this project were calculated using a combination of refinery specific information
(throughput, tank refills and cleaning operations), emission factors from AP-42, and using the Protocol for Equipment Leak Estimates. UDAQ has reviewed the assumptions and calculations submitted by TLO and concurs with the results. [Last updated July 18, 2024]

1 Introduction
This Notice of Intent (NOI) package is submitted for approval of the proposed ethanol tank project at the
Tesoro Logistics Operations LLC (TLO) Salt Lake City Truck Loading Rack (TLR) (hereinafter referred to
as the “Project”). The TLR currently operates under Approval Order (AO) DAQE-AN156590009-23 and
Title V operating permit 3500008002, which are affected by this Project. TLO is a subsidiary of Marathon
Petroleum Corporation (Marathon). This project does not involve Tesoro Refining & Marketing Company
LLC’s Salt Lake City Refinery, which is also a fully owned subsidiary of Marathon.
This Project involves adding storage capacity at the facility by refurbishing Tank 509 for denatured
ethanol storage. Tank 509 is currently out of service and not listed in the AO or Title V operating permit.
Utah administrative code Rule R307-401-3(a) requires submittal of an NOI to “construct a new installation
which will or might reasonably be expected to become a source or an indirect source of air pollution.”
Rule R307-401-3(b) requires submittal of an NOI to “make modifications or relocate an existing
installation which will or might reasonably be expected to increase the amount or change the effect of, or
the character of, air contaminants discharged, so that such installation may be expected to become a
source or indirect source of air pollution.”
Rule R307-401-5 requires that the NOI must contain specific information related to the process, nature of
emissions, control device(s), and regulatory applicability and compliance. This NOI includes a project
description, an emissions summary, and a description of regulatory applicability and demonstration of
compliance to address these requirements.
This NOI is organized as follows:
• Section 2.0 contains a project description,
• Section 3.0 contains the emissions summary,
• Section 4.0 contains a description of regulatory applicability and compliance demonstration,
• Section 5.0 contains a summary of the NOI requirements,
• Attachment A contains a site diagram,
• Attachment B contains the Project emission calculations,
• Attachment C contains control cost evaluation calculations,
• Attachment D contains the UDAQ permitting forms.

2 Project Description
This section includes a general description of the facility and details of the proposed Project.
2.1 General Facility Information
The TLR is located at 475 West 900 North, Salt Lake City, Utah. The TLR is located in a nonattainment
area for SO2, PM2.5 (including precursors SO2, NOx, VOC, and NH3), and ozone (including precursors SO2
and NOx).1 The area is also a designated maintenance area for PM10 and CO.1 Attachment A includes a
figure that shows the location of the facility in Salt Lake City.
2.2 Project Description
This Project involves adding denatured ethanol storage capacity at the facility by refurbishing Tank 509.
Denatured ethanol is purchased and then blended with gasoline product loaded at TLR. Additional
storage capacity is needed to manage materials during an upcoming mandatory inspection of the existing
ethanol storage tank in 2026. Additional storage capacity will also reduce TLO’s reliance on third-party
shipping and storage facilities. Tank 509 has a storage capacity of 20,000 bbl and is currently out of
service. The out of service tank was inherited by TLO as part of the original property acquisition and has
not been operated by TLO since the time of purchase. Tank 509 will be retrofitted with an internal floating
roof to control emissions from denatured ethanol storage.
Facility diagrams showing the location of the equipment are included in Attachment A.
2.3 Affected Emission Units
The project affects the following emission units:
• Tank 509 will be refurbished and re-commissioned for denatured ethanol service.
• New fugitive components in VOC service to support the construction.
2.4 Emission Units Not Affected by Project
TLO has evaluated the Project impacts to other portions of the terminal and refinery, and has determined
that no other emission units are affected by the Project. This project will not result in additional gasoline
product loaded at TLR.
2.5 Project Schedule
The estimated start of construction is January 1, 2025, pending permit approval. Operations are expected
to commence in June 2025, assuming permit approval by the estimated date for start of construction.

1 Nonattainment statuses determined based on review of USEPA’s Nonattainment and Maintenance Area Dashboard as of April 18, 2024. Available as of this date at: https://awsedap.epa.gov/public/extensions/specs-area-dashboard/index.html

3 NSR Applicability Analysis
Permits are required for new or modified sources that will or might reasonably be expected to increase
the amount or change the effect of air contaminants discharged under R307-401. With this Project, an
emissions increase will occur; therefore, an Approval Order is required under R307-401.
Utah rules implement the New Source Review (NSR) permitting program for major sources and major
modifications. TLO is currently a major source as defined in Utah Rule R307-100. Pollutant-specific
emission calculations must also be completed to determine whether a major modification will occur under
R307-403 for nonattainment and maintenance areas and under R307-405 for attainment areas. This
project involves only VOC emissions increases, which is regulated under R307-403. TLO has completed
an applicability analysis to determine if this Project is a major modification.
For R307-403, a major modification is defined under R307-101-2 as “any physical change in or change in
the method of operation of a major source that would result in a significant net emissions increase of any
pollutant…”. The net emissions increase is quantified as “the amount by which the sum of the following
exceeds zero: (1) any increase in actual emissions from a particular physical change or change in method
of operation at a source…”.
3.1 Major NSR Applicability
An NSR applicability analysis has been conducted for the Project to determine if a “significant emissions
increase” and a “significant net emissions increase” of a “regulated NSR pollutant” will occur, making it a
“major modification” under NSR regulations.2
An increase is significant if it exceeds the annual ton per year (tpy) thresholds known as the significant
emission rates, which are listed in Table 3-1 for only those regulated NSR pollutants that are emitted in
quantifiable amounts from emission units affected by this project.
Table 3-1. NSR Significant Emission Rates
Pollutant[1] Significant Emission Rate (tpy)
Volatile Organic Compounds (VOC) 40 [2]
[1] Only those NSR pollutants that are emitted in quantifiable amounts from emission units affected by this project are shown in the table. [2] The NSR significant emission rate is assessed based on emissions of volatile organic compounds (VOC) as a precursor to ozone and PM2.5.
The project emissions increase is calculated as the sum of emissions increases from the new emissions
units that are impacted by this project. If the project emissions increase for a regulated NSR pollutant is
less than the significant emission rate, NSR is not required for that pollutant.

2 40 CFR 52.21(a)(2)(iv)(a) or 51.165(a)(1)(v)

3.1.1 New and Existing Emissions Units: Actual-to-Potential Test
The actual-to-potential applicability test is described as the following:3
“Actual-to-potential test for projects that only involve construction of a new emissions unit(s). A
significant emissions increase of a regulated NSR pollutant is projected to occur if the sum of the difference between the potential to emit (as defined in paragraph (a)(1)(iii) of this section) from each
new emissions unit following completion of the project and the baseline actual emissions (as defined in paragraph (a)(1)(xxxv)(C) of this section) of these units before the project equals or exceeds the
significant amount for that pollutant (as defined in paragraph (a)(1)(x) of this section).”
The terms “new emissions unit,” “baseline actual emissions” (BAE), and “potential to emit” as used in this
paragraph have specific meanings ascribed by the applicable rules. A “new emissions unit” is any part of
a stationary source that emits any regulated NSR pollutant and is or will be newly constructed and has
existed for less than two years from the date the unit first began operating. The BAE for a new emissions
unit is zero prior to initial operation and is equal to the unit's potential to emit for the first two years of
operation.
“Potential to emit” is defined as:
“… [t]he maximum capacity of a stationary source to emit a pollutant under its physical and
operational design. Any physical or operational limitation on the capacity of the source to emit a
pollutant, including air pollution control equipment and restrictions on hours of operation or on the
type or amount of material combusted, stored, or processed, shall be treated as part of its design
if the limitation or the effect it would have on emissions is federally enforceable…”
The PTE for an emissions unit yet to be constructed is generally calculated as the product of its hourly
maximum throughput or heat input capacity and an uncontrolled emission factor, which may be found in
EPA guidance (e.g., AP-42), a manufacturer performance guarantee, existing regulatory standards (e.g.,
NSPS ), or other information sources. Enforceable emission limitations on the capacity of the source to
emit a pollutant (e.g., air pollution control equipment, restriction on hours of operation) may be taken to
reduce the unit’s PTE.
3.2 Affected Emissions Units
3.2.1 Storage Tank 509
Potential emissions were estimated using emissions calculation methodology consistent with AP-42
Chapter 7.1 for organic liquid storage tanks. This includes routine operations and a planned landing and
degassing event associated with internal inspections. Attachment B contains detailed emission
calculations which summarize the potential emissions of Tank 509.
3.2.2 Fugitive Components
The Project will involve construction of new fugitive components in VOC service. Potential emissions of
leaks from these components were estimated using the EPA’s Protocol for Equipment Leak Emission

3 40 CFR 51.165(a)(2)(ii)(D)

5

Estimates for equipment leak emissions. Attachment B contains detailed emission calculations which
summarize the potential emissions of the fugitive components associated with this Project.
3.3 Project Emissions Increase Summary
Table 3-2 presents a summary of the Project emissions increase. The Project VOC emissions increase
are less than their respective NSR significant emission rates, therefore the Project does not trigger NSR
for VOCs.
Table 3-2. Tank Project Emissions Increases (tpy)
Emission Unit VOC
Tank 509 0.31
New and Replaced Components 0.70
Project Emissions Increase 1.01
NSR Significant Emission Rate (SER) 40
Is Project Emissions Increase > SER? No

3.4 “Reasonable Possibility” Requirements
On December 21, 2007, the US EPA promulgated updates to the federal PSD rules at 40 CFR
52.21(r)(6)(vi) that defines when an owner/operator of a major source is required to conduct
recordkeeping and reporting when using the baseline-actual-to-projected-actual emissions increase
calculation methodology. TLO has not used this methodology for this Project; therefore, the requirements
do not apply.

4 Regulatory Applicability and Compliance Demonstration
TLO has completed an applicability review of all Federal and State air quality regulations as part of the air
permit application process. Table 4-1 provides a summary of the major air quality programs that were
reviewed for the Project. Each regulation which requires explanation is described in the following

4.1 Rule R307-110. General Requirements: State Implementation
Plan
The PM2.5 State Implementation Plan (SIP), as most recently amended by the Utah Air Quality Board on
December 4, 2019, is incorporated by reference and made part of Utah rules pursuant to R307-110-10.
TLO will comply with requirements located in Sections IX.H.11.g.vi for control of tank degassing
emissions if the stored material has a true vapor pressure equal or greater than 1.52 psia at the time of
degassing. TLO has assumed the requirements apply..
Section IX.H.11.g.i of the PM2.5 SIP contains requirements for petroleum refineries; however, the tanks
involved with this project are not subject to requirements under the SIP.
4.2 R307-210: Stationary Sources
New Source Performance Standards (NSPS) are incorporated by reference into the UDAQ rules. There is
no new construction of any NSPS affected facilities. TLO reviewed whether the Project will result in a
“modification” or “reconstruction” for any NSPS affected facilities, and thus result in applicability of that
NSPS. The NSPS regulation, at 40 CFR §60.14(a), defines a modification as a physical or operational
change to the affected facility that is not specifically exempted and that results in an increase in the
emissions rate to the atmosphere of any pollutant to which a standard applies. An increase in production
rate, if that increase can be accomplished without a capital expenditure on that facility, is not considered a
modification per §60.14(e)(2). “Increase in emissions rate” is defined pursuant to §60.14(b) as an
increase in the maximum hourly emission rate of an applicable pollutant from the affected facility. A
reconstruction occurs when the fixed capital cost of the Project is 50 percent or greater than the current
replacement cost of the affected facility.

8

The physical changes performed as part of the Project affect storage tanks by refurbishing and retrofitting
Tank 509. Additionally, new fugitive components in VOC service will be installed. Applicability of these
changes to 40 CFR 60 Subparts Kb, Kc, and GGGa are discussed below in additional detail.
Regulatory coverage for other NSPS subparts currently applicable to the facility are as follows: 40 CFR
60 Subparts A, Db, J, Ja, K, Ka, GG, GGG, NNN, and QQQ. These are listed in Section III of the AO and
will not change as a result of this Project.
4.2.1 Subpart Kb: Standards of Performance for Volatile Organic Liquid
Storage Vessels (Including Petroleum Liquid Storage Vessels) for
Which Construction, Reconstruction, or Modification Commenced
After July 23, 1984
The refurbished Tank 509 will experience an increase in the maximum hourly emission rate as a result of
storing materials of a higher vapor pressure than current operations. Therefore, a “modification” will occur
and Tank 509 will be subject to NSPS Subpart Kb for Volatile Organic Liquid Storage Vessels. The tank
will be retrofitted with an internal floating roof which meets the specifications listed in 40 CFR
60.112b(a)(1), and TLO will be subject to the corresponding monitoring, recordkeeping, and reporting
requirements.
4.2.2 Subpart Kc: Standards of Performance for Volatile Organic Liquid
Storage Vessels (Including Petroleum Liquid Storage Vessels) for
Which Construction, Reconstruction, or Modification Commenced
After [THE DATE OF PUBLICATION OF THE PROPOSED RULE IN
THE FEDERAL REGISTER]
Subpart Kc is a proposed rule regulating volatile organic liquid storage vessels. If the proposed rule is
finalized as currently proposed, Tank 509 will undergo a “modification” when refurbished for service and
become subject to Subpart Kc in lieu of Subpart Kb. The tank would then meet the specifications of
Subpart Kc and be subject to the corresponding monitoring, recordkeeping, and reporting requirements.
4.2.3 Subpart GGGa: Standards of Performance for Equipment Leaks of
VOC in Petroleum Refineries for Which Construction,
Reconstruction, or Modification Commenced After November 7,
2006
Subpart GGGa regulates equipment leaks from the group of all the equipment in VOC service within a
process unit that are constructed, reconstructed, or modified after November 7, 2006 at a petroleum
refinery. TLO is already subject to 40 CFR 60 Subpart GGGa for equipment leaks. New and replaced
components added as part of the Project are subject to Subpart GGGa.
4.3 R307-214: National Emission Standards for Hazardous Air
Pollutants
NESHAP standards from 40 CFR 61 and 40 CFR 63 are incorporated by reference into the UDAQ rules.
TLO is currently subject to 40 CFR 63 Subpart CC for “National Emission Standards for Hazardous Air

9

Pollutants from Petroleum Refineries” because the TLO facility is considered part of the same stationary
source as the refinery. Storage vessels and equipment leaks are regulated as emission points under this
subpart, so the new tank and components associated with this project will be subject to Subpart CC. TLO
will continue to comply with the emission standards and other requirements of this rule. TLO will comply
with Subpart CC for the tanks by either (1) complying with NSPS Subpart Kb if not subject to NSPS
Subpart Kc, or (2) complying directly with the requirements of Subpart CC, which incorporates
requirements under Subpart WW. No new requirements will be triggered as a result of this Project.
Regulatory coverage for other subparts currently applicable to the facility (40 CFR 61 Subparts A, M, and
FF and 40 CFR 63 Subparts UUU, EEEE, and DDDDD as listed in Section III of the AO) will not change
as a result of this Project
4.4 R307-326: Ozone Nonattainment and Maintenance Areas:
Control of Hydrocarbon Emissions in Petroleum Refineries
Rule R307-326-9 contains requirements for leaks from petroleum refinery equipment. The TLO facility is
considered part of the same stationary source as the refinery. Although tank valves are exempt from
monitoring requirements per R307-326-9(4)(a), components on the tanks will be subject to the repair,
recordkeeping, and reporting requirements of the rule. Following the Project, TLO will continue to comply
with the requirements of this rule for existing tanks involved in the Project as well as for the new or
refurbished tank.
4.5 R307-327: Ozone Nonattainment and Maintenance Areas:
Petroleum Liquid Storage
Rule R307-327 contains requirements for storage vessels in ozone nonattainment or maintenance areas.
TLO has assumed that the maximum true vapor pressure of denatured ethanol may exceed 1.52 psia and
that Tank 509 will be subject to this rule. Tank 509 will have an internal floating roof which will comply
with R307-327-4(1).
4.6 R307-401: Permit: New and Modified Sources
Rule R307-401-3(a) requires submittal of an NOI to “construct a new installation which will or might
reasonably be expected to become a source or an indirect source of air pollution.” Since the Project
involves a new installation of a source of air pollution, an NOI must be submitted. Rule R307-401-5
requires submittal of an NOI, which must contain specific information related to the process, nature of
emissions, control device(s), and regulatory applicability and compliance. Refer to Section 5.0 for a
summary of compliance with the NOI requirements.
4.6.1 State BACT
R307-401-5(d) permits the issuance of an approval order if it is determined that the pollution control for
emissions is at least best available control technology (BACT). A BACT review is required for new
emission units and existing emission units where there is a physical modification and an increase in
emissions.
TLO will install an internal floating roof with secondary seals on Tank 509 to reduce VOC emissions.
Internal floating roofs with secondary seals are the top available control option for storage tanks in
ethanol service. Additionally, TLO will control degassing emissions.

10

An alternative control approach for the tank would be installing a closed vent system to a thermal oxidizer
(TO). TLO considered this control option; however, this method is likely not a viable option since large
amounts of natural gas would be consumed to generate the heat required to meet minimum temperature
requirements in the TO. The natural gas usage would add significant costs to operations while
simultaneously increasing greenhouse gas emissions for minimal reductions in potential VOC emissions.
TLO performed a high-level cost evaluation of TO control for Tank 509 and determined the cost
effectiveness to be in excess of $400,000 per ton of VOC controlled, which is not economically feasible.
Details of the cost evaluation are included in Attachment C. This cost evaluation is solely for the
installation and operation of the TO itself. A TO would also require the installation of a closed vent
system, which would involve additional piping, blowers, detonation arrestors, equipment supports, utility
infrastructure, and pressure sensing and control devices. All of these items would further decrease the
cost effectiveness of this control option.
Fugitive components will meet BACT by meeting NSPS GGGa.
4.7 R307-403: Nonattainment and Maintenance Areas
R307-403 applies to major new sources or major modifications to be located in a nonattainment area.
The TLR is located in a nonattainment area for PM2.5 (including precursors SO2, NOx, and VOC), PM10
(including precursors SO2 and NOx), and SO2. The proposed Project is neither a new major source nor a
major modification as defined in R307-101-2 since the actual emissions increase of PM2.5, PM10, and SO2
is zero, which is less than the significant emission rate (SER) threshold for each applicable pollutant.
Emission offsets are required if the combined allowable emission increase of PM10, SO2, and NOx
exceeds 25 tons per year per R307-403-5. Since the combined allowable emission increase from the
Project is zero tons per year of these pollutants, no emission offsets are required.
4.8 R307-405: Permits: Major Sources in Attainment or Unclassified
Areas (PSD)
This project is not a major modification and is not subject to the PSD program as described in Section
3.3. TLO has demonstrated compliance with all applicable requirements with the submission of this NOI.
Therefore the requirements of R307-405 are not applicable to this proposed project.
4.9 R307-406: Visibility
R307-406 addresses adverse impacts on visibility from proposed new major sources or a major
modification. This project is not a new major source or a major modification; therefore, the requirements
of R307-406 are not applicable to this proposed project.
4.10 R307-410: Permits: Emissions Impact Analysis
R307-410 establishes the procedures and requirements for evaluating the emissions impact of new or
modified sources. Pursuant to R307-410-4, dispersion modeling is required for increases in the total
controlled emission rate of attainment pollutants (NOx and CO) in an amount greater or equal to values
given in Table 1 of the rule. For these pollutants, the thresholds given in Table 1 are equal to the SERs.
Dispersion modeling is not required since there is not an increase in emissions of NOx or CO.

11

4.10.1 R307-410-5: Ambient Air Impacts for Hazardous Air Pollutants
The requirements of R307-410-5 do not apply to installations which are subject to or are scheduled to be
subject to an emission standard promulgated under 42 USC 7412 at the time the NOI is submitted. As
described in Section 4.3, the tanks and new components are all subject to standards under 40 CFR 63
Subparts CC. The requirements of R307-410-5 do not apply to the project.
Potential HAP emission increases are associated with the tanks involved with this project. Table 4-2
presents a summary of potential HAP emission increases. Refer to Attachment B for detailed HAP
emission calculations.
Table 4-2. Project Potential HAP Emissions Increase Summary
HAP Project Potential Emissions Increase (lb/yr)
Benzene 0.48
Ethylbenzene 0.05
Hexane 0.85
Iso-octane (2,2,4 trimethylpentane) 0.42
Isopropyl benzene 5.29E-03
Toluene 0.69
Xylenes 0.26
Total 2.76

4.11 R307-420: Permits: Ozone Offset Requirements in Davis and
Salt Lake Counties
Emission offsets are required for any new major source or major modification of VOC or NOx. R307-420-2
defines a significant emission increase at a level of 25 tpy VOC rather than 40 tpy VOC. The Project is
neither a new major source nor a major modification for VOC (considering the lower threshold) or NOx;
therefore, offsets are not required.
4.12 R307-421: Permits: PM10 Offset Requirements in Salt Lake
County and Utah County
Emission offsets are required if the combined allowable emission increase of SO2 and NOx exceeds 25
tons per year. The combined allowable emission increase of these pollutants from the Project is 0 tons
per year. Therefore, no emission offsets are required.

12
