Project Description
HAFB has requested a modification to AO DAQE-AN112840026-17 to add one diesel-fired generator
engine. The addition of the diesel-fired generator engine will not increase the PTE emissions since the
HAFB, UTTR has a diesel consumption limit of 225,000 gallons per calendar year, and the fuel
consumption limit is not increasing. The HAFB, UTTR AO will be updated from the 2017 format.

Process Description
HAFB, UTTR is located in Box Elder and Tooele Counties, about 70 miles west of Salt Lake City. UTTR
encompasses approximately 11,000,000 acres of designated Military Operating Airspace (MOA) and
approximately 1,000,000 acres of land area. Approximately 1,000,000 acres of land are divided into two
noncontiguous ranges, the UTTR North Range and the UTTR South Range, each with several areas
appropriated for munitions storage, testing, and training. The UTTR North Range includes the TTU, the
Missile Test Area, the Oasis and Eagle maintenance facilities, numerous target and test areas, and the
Helicopter Air/Ground (HAG) bomb training area. The Bovine Mountain and Trout Creek remote radar
sites support North and South Range activities. The TTU provides open OB/OD services to all branches
of the armed services. Bomb and gunnery training areas on both the North Range and the South Range are
also used by all branches of the armed services. The UTTR South Range, abutting Dugway Proving
Grounds, is used primarily for test and training, such as inert and live bomb drop activities. HAFB, UTTR
is a major source of PM10, PM2.5, NOX, and HAP emissions. HAFB, UTTR is subject to 40 CFR 60

Review of BACT for New/Modified Emission Units 1. BACT review regarding Diesel Emergency Generators
Diesel-fired Generator HAFB conducted a BACT analysis for the use of a diesel-fired generator with the following control technologies: good combustion practices, Use of Low-Sulfur Fuel, 40 CFR Part 60 Subpart
IIII, 40 CFR Part 63 Subpart ZZZZ, Selective Catalyst Reduction (SCR), Good Combustion Practices: Include official documentation and training in operating and maintenance procedure, including procedures for startup, shutdown and malfunction; routine inspection and preventative maintenance procedures; equipment overhaul and include recordkeeping of operating logs and maintenance records. Good combustion practices reduce emissions of all criteria pollutants. Use of Low-Sulfur Diesel (0.05%): Reduces SOx emissions and shall be considered BACT for all generator engines. 40 CFR Part 60 Subpart IIII 'Standards of Performance for Stationary Compression Ignition Internal Combustion Engines' requires owners and operators of non-emergency and emergency affected engines to comply with emission standards (Tier standards) based on engine model year, maximum engine power, engine displacement and use (emergency, non-emergency). The Tier standards are emission limits for PM, CO and NMHC + NOx or NOx and NMHC. The subpart
requires proper operation and maintenance, in accordance with the manufacturer, to ensure affected emission units achieve the applicable Tier standards over the entire life of the engine. The subpart requires affected emission units with a displacement of less than 30 liters per cylinder to
comply with fuel sulfur limitations (except that any existing diesel fuel purchased or otherwise obtained prior to October 1, 2010 may be used until depleted): (1) fuel sulfur content no greater than 15 ppm (0.0015 percent) by weight and (2) a minimum cetane index of 40 or a maximum
aromatic content of 35 volume percent. 40 CFR Part 63 Subpart ZZZZ 'National Emission Standards for Hazardous Air Pollutants for Stationary Reciprocating Internal Combustion Engines' requires owners and operators of non-emergency and emergency affected engines to at all times operate and maintain any affected
source in a manner consistent with safety and good air pollution control practices for minimizing emissions. The subpart requires compliance with operating limitations for existing (commenced construction or reconstruction before June 12, 2006) non-emergency affected emission units rated
less than 100 HP which includes requirements for: (1) changing oil and air filter, inspection / replacement of air cleaner and inspection / replacement of hoses and belts and (2) minimizing time spent at idle and minimizing engine's start up time.
Selective Catalyst Reduction (SCR): Is a combination of engineered components designed to reduce the amount of NOx in a turbine or engine exhaust stream. A form of ammonia is injected in front of a catalyst to reduce the NOx. Nitrogen oxides are formed when the oxygen and nitrogen in the air react with each other during combustion. High temperatures and excess oxygen (more
than is needed to burn the fuel) favor the formation of nitrogen oxides. SCR systems are installed to reduce NOx levels in the exhaust gas stream from the engine. SCR systems have the capability of reducing both NO and NO2 in the gas stream by injecting an ammonia reagent ahead of the
catalyst. In addition to NOx control, SCR systems with an oxidation catalyst can also reduce CO emissions. All of the technologies listed above for control of emissions from diesel generators are technically

Engineer Review N112840030: Hill Air Force Base- Utah Test and Training Range April 30, 2025 Page 7
feasible.
Additionally, the generator will be turbocharged air-to-air aftercooled and will be equipped with a diesel particulate filter and an aftertreatment system. The primary function of the aftertreatment system is to reduce the undesirable exhaust emissions. Through this process, NOX reacts with diesel exhaust fluid across catalysts within the clean emission module and gets converted into nitrogen and water before releasing them into the atmosphere. The clean emission module includes diesel oxidation catalyst and selective catalytic reduction.
BACT for the diesel-fired generator is good operating practices, use of low-sulfur diesel fuel, and compliance with applicable NSPS IIII requirements, compliance with applicable NESHAP ZZZZ requirements, the use of clean emissions module and a 20% opacity limit. [Last updated April 24, 2025]

PERMIT HISTORY When issued, the approval order shall supersede (if a modification) or will be based on the
following documents: Supersedes DAQE-AN112840026-17 dated May 24, 2017
Is Derived From Notice of Intent dated February 26, 2025 Incorporates Additional Information dated April 24, 2025
REVIEWER COMMENTS 1. Comment regarding Emission Estimates: HAFB, UTTR has an existing diesel consumption limit in the AO. HAFB is not requesting to increase the diesel consumption limit for the new engine, so the PTE emissions are not increasing with the addition of the generator engine. [Last updated April 24, 2025] 2. Comment regarding Project Type: HAFB, UTTR requested to add a generator engine with the capacity over 600 hp (778 hp) but not to increase the diesel consumption limit. There are no increases in PTE's since the diesel consumption limit is not increasing. This permit change adding the generator engine is being conducted a minor modification to a major source. [Last updated April 24, 2025]
3. Comment regarding Major Source Classification: HAFB, UTTR is classified as major source for PM10 (241.25 TPY), PM2.5 (241.25 TPY), NOx
(111.27 TPY), and HAP emissions (315.46 TPY combined HAPs and over 10 TPY for two single HAPs). HAFB, UTTR has not separated fugitive emissions from point source emissions, so all emissions are considered point source. CO2e emissions have not been considered until now. The
CO2e emissions are not considered new emissions since they have been assumed to be there but not taken into consideration until now. [Last updated April 24, 2025] 4. Comment regarding MRR's: The monitoring, recordkeeping and reporting requirements are contained in the Title V permit and since both permits (AO and Title V) are required for the source to operate they were removed from the AO. [Last updated April 24, 2025] 5. Comment regarding Additional Information: Additional information was submitted by HAFB for the CO2e emissions. These emissions have never been accounted for until now. The emissions have been assumed to be there and not considered new. [Last updated April 24, 2025]

Hill Air Force Base (HAFB), Utah Test and Training Range (UTTR) is located in Box Elder and Tooele
Counties, about 70 miles west of Salt Lake City. UTTR encompasses approximately 11,000,000 acres of
designated Military Operating Airspace (MOA) and approximately 1,000,000 acres of land area.
Approximately 1,000,000 acres of land is divided into two noncontiguous ranges, the UTTR North Range and
the UTTR South Range, each with several areas appropriated for munitions storage, testing and training. The
UTTR North Range includes the Thermal Treatment Unit (TTU), the Missile Test Area, the Oasis and Eagle
maintenance facilities, numerous target and test areas, and the Helicopter Air/Ground (HAG) bomb training
area. The Bovine Mountain and Trout Creek remote radar sites support North and South Range activities. The
TTU provides open burn/open detonation (OB/OD) services to all branches of the armed services. Bomb and
gunnery training areas on both the North Range and the South Range are also used by all branches of the armed
services. The UTTR South Range, abutting Dugway Proving Ground, is used primarily for test and training
such as inert and live bomb drop activities. HAFB UTTR is a major source of PM10, PM2.5, NOx and HAP
emissions. HAFB UTTR is subject to 40 CFR 60 Subpart A-General Provisions, 40 CFR 60 Subpart IIII-
Standards of Performance for Stationary Compression Ignition Internal Combustion Engines, 40 CFR 62

Code R307-101 and R307-415 (Rules), and 40 Code of Federal Regulations (CFR), except as otherwise
defined in this permit. Unless noted otherwise, references cited in the permit conditions refer to the Rules.

Where a permit condition in Section I, General Provisions, partially recites or summarizes an applicable
rule, the full text of the applicable portion of the rule shall govern interpretations of the requirements of the
rule. In the case of a conflict between the Rules and the permit terms and conditions of Section II, Special
Provisions, the permit terms and conditions of Section II shall govern except as noted in Provision I.M,
Permit Shield.

I.A Federal Enforcement.

All terms and conditions in this permit, including those provisions designed to limit the
potential to emit, are enforceable by the EPA and citizens under the Clean Air Act of 1990
(CAA) except those terms and conditions that are specifically designated as "State

I.B Permitted Activity(ies).

Except as provided in R307-415-7b(1), the permittee may not operate except in compliance
with this permit. (See also Provision I.E, Application Shield)

I.C Duty to Comply.

I.C.1 The permittee must comply with all conditions of the operating permit. Any permit
noncompliance constitutes a violation of the Air Conservation Act and is grounds for any of
the following: enforcement action; permit termination; revocation and reissuance;
modification; or denial of a permit renewal application. (R307-415-6a(6)(a))

I.C.2 It shall not be a defense for a permittee in an enforcement action that it would have been
necessary to halt or reduce the permitted activity in order to maintain compliance with the
conditions of this permit. (R307-415-6a(6)(b))

I.C.3 The permittee shall furnish to the Director, within a reasonable time, any information that
the Director may request in writing to determine whether cause exists for modifying,
revoking and reissuing, or terminating this permit or to determine compliance with this
permit. Upon request, the permittee shall also furnish to the Director copies of records
required to be kept by this permit or, for information claimed to be confidential, the
permittee may furnish such records directly to the EPA along with a claim of
confidentiality. (R307-415-6a(6)(e))

I.C.4 This permit may be modified, revoked, reopened, and reissued, or terminated for cause.
The filing of a request by the permittee for a permit modification, revocation and
reissuance, or termination, or of a notification of planned changes or anticipated
noncompliance shall not stay any permit condition, except as provided under R307-415-
7f(1) for minor permit modifications. (R307-415-6a(6)(c))

I.D Permit Expiration and Renewal.
Project OPP0112840014 Page 7 Title V Operating Permit #300036005

"Enforceable Dates and Timelines" at the front of this permit. An application may be
submitted early for any reason. (R307-415-5a(1)(c))

I.D.3 An application for renewal submitted after the due date listed in I.D.2 above shall be
accepted for processing, but shall not be considered a timely application and shall not
relieve the permittee of any enforcement actions resulting from submitting a late
application. (R307-415-5a(5))

I.D.4 Permit expiration terminates the permittee's right to operate unless a timely and complete
renewal application is submitted consistent with R307-415-7b (see also Provision I.E,
Application Shield) and R307-415-5a(1)(c) (see also Provision I.D.2). (R307-415-7c(2))

I.E Application Shield.

If the permittee submits a timely and complete application for renewal, the permittee's
failure to have an operating permit will not be a violation of R307-415, until the Director
takes final action on the permit renewal application. In such case, the terms and conditions
of this permit shall remain in force until permit renewal or denial. This protection shall
cease to apply if, subsequent to the completeness determination required pursuant to R307-
415-7a(3), and as required by R307-415-5a(2), the applicant fails to submit by the deadline
specified in writing by the Director any additional information identified as being needed to
process the application. (R307-415-7b(2))

I.N.1 An "emergency" is any situation arising from sudden and reasonably unforeseeable events
beyond the control of the source, including acts of God, which situation requires immediate
corrective action to restore normal operation, and that causes the source to exceed a
technology-based emission limitation under this permit, due to unavoidable increases in
emissions attributable to the emergency. An emergency shall not include noncompliance to
the extent caused by improperly designed equipment, lack of preventive maintenance,
careless or improper operation, or operator error. (R307-415-6g(1))

requirements in this permit. (R307-415-6g(3)(c))

I.N.2.d The permittee submitted notice of the emergency to the Director within two
working days of the time when emission limitations were exceeded due to the
emergency. This notice must contain a description of the emergency, any steps
taken to mitigate emissions, and corrective actions taken. This notice fulfills the
requirement of Provision I.S.2.c below. (R307-415-6g(3)(d))

I.N.3 In any enforcement proceeding, the permittee seeking to establish the occurrence of an
emergency has the burden of proof. (R307-415-6g(4))

I.N.4 This emergency provision is in addition to any emergency or upset provision contained in
any other section of this permit. (R307-415-6g(5))

This operating permit incorporates all applicable requirements contained in the following documents:

Incorporates DAQE-AN112840026-17 dated May 24, 2017

1. Comment on an item originating in 40 CFR 63 Subpart ZZZZ regarding Permitted Source
Applicability of 40 CFR 63 Subpart ZZZZ: The permittee shall meet the requirements of
40 CFR 63, Subpart ZZZZ by meeting the requirements of 40 CFR 60, Subpart IIII in
accordance with 40 CFR 63.6590(c) for new or reconstructed compression ignition
engines less than or equal to 500 Hp.

According to 40 CFR 63.6590(a)(1)-(3), for major sources of HAP emissions:
New or reconstructed RICE are RICE with a site rating of more than 500 brake hp for
which construction or reconstruction is commenced on or after December 19, 2002, or
RICE with a site rating of less than or equal to 500 brake hp for which construction or
reconstruction is commenced on or after June 12, 2006. Existing RICE are RICE with a
site rating of more than 500 brake hp for which construction or reconstruction is
commenced before December 19, 2002, or RICE with a site rating of less than or equal to
500 brake hp for which construction or reconstruction is commenced before June 12, 2006.

The permittee has reevaluated the definition of limited use stationary RICE in 40 CFR 63
Subpart ZZZZ and has not identified any affected emission units onsite that meet the
definition.

Per 40 CFR 63.6590(b)(3), existing emergency stationary RICE with a site rating of more
than 500 brake HP located at a major source of HAP emissions that do not operate or are
not contractually obligated to be available for more than 15 hours per calendar year for the
purposes specified in 40 CFR 63.6640(f)(2)(ii) and (iii) do not have to meet the
requirements of 40 CFR 63 Subpart A and Subpart ZZZZ, including initial notification
requirements.

The permittee has reviewed the ICE units throughout the base and determined they will not
be used for emergency demand response and/or voltage deviation purposes. For this
reason, language originating in 40 CFR 63.6640(f)(2)(ii)-(iii) has not been included in the
permit.
[7/1/2009] [Last updated January 10, 2022]

2. Comment on an item originating in 40 CFR Part 64 regarding Permitted Source
Compliance Assurance Monitoring (CAM): CAM applicability has been evaluated. There
are no CAM requirements in this permit. [7/7/2010] [Last updated January 10, 2022]

3. Comment on an item originating in R307-205 regarding Permitted Source
Fugitive emissions: The referenced rule limits opacity from fugitive emissions to no
greater than 40% opacity from sources constructed before April 25, 1971 and no greater
than 20% opacity from sources constructed after April 25, 1971. UAC R307-101-2
defines "fugitive emissions" as "emissions from an installation or facility which are neither
passed through an air cleaning device nor vented through a stack or could not reasonably
pass through a stack, chimney, vent, or other functionally equivalent opening." Because
OB/OD, missile testing, testing and training, and range maintenance are not considered
installations, fugitive emissions from these operations are not considered "fugitive
Project OPP0112840014 Page 52 Title V Operating Permit #300036005

emissions" as defined in UAC R307-101-2. Therefore, the 20% opacity limit does not
apply to those operations. [1/28/2003] [Last updated January 10, 2022]

4. Comment on an item originating in DAQE-AN0143430001-11 regarding Permitted Source
JLENS equipment operating at the UTTR: On February 4, 2010 and March 4, 2010, Hill
AFB UTTR submitted seven-day flexibility notifications, pursuant to Conditions II.B.1.e
and II.B.4.d in the permit issued 7/30/2009, respectively, to install and operate new
internal combustion engines for emergency power and new aboveground storage tanks at
Diddle Knoll at the UTTR. This equipment is operated by the Department of the Army's
Joint Land Attack Cruise Missile Defense Elevated Netted Sensory System (JLENS)
group. JLENS activities, while located at the UTTR, are not under Hill AFB's control and
Hill AFB has no operational involvement. As a result, Approval Order DAQE-
AN0143430001-11 was issued by UDAQ on March 14, 2011 for the Department of the
Army, and covers the JLENS equipment. The seven-day flexibility notifications are no
longer applicable to the JLENS equipment because the JLENS engines and tanks have
been included in the Army Approval Order, DAQE-AN0143430001-11. [4/14/2011] [Last
updated January 10, 2022]

5. Comment on an item originating in 40 CFR 63 Subpart ZZZZ regarding Permitted Source
Mobile Source Excluded from Title V: The HAFB UTTR Title V permit only applies to
stationary sources. As defined in 40 CFR 63 Subpart ZZZZ, "A stationary RICE is any
internal combustion engine which uses reciprocating motion to convert heat energy into
mechanical work and which is not mobile. Stationary RICE differ from mobile RICE in
that a stationary RICE is not a non-road engine as defined at 40 CFR 1068.30, and is not
used to propel a motor vehicle or a vehicle used solely for competition." 40 CFR 1068.30
specifies that portable engines that remain at a location for more than 12 consecutive
months would also be included under the definition of stationary RICE. Based on this
definition, aerospace ground equipment (AGE) and generators used in field training
exercises would not be considered stationary and are not subject to the Title V permit.
[7/1/2009] [Last updated January 10, 2022]

6. Comment on an item originating in renewal permit issued 12/7/2005 regarding Permitted Source
Definition of "Prompt": "Prompt," as defined in Provision I.S.2.c, has been changed to 21
days. The primary reason for the change is because the military chain of command is
extensive. For any documents going to the UDAQ or EPA, a large number of people in
the chain of command must review and agree before the documents can be sent forward to
the Responsible Official for final signature. A 21-day definition of prompt has proven to
be an effective time frame for all of the required parties to review all submitted documents.
[8/15/2005] [Last updated January 10, 2022]

7. Comment on an item originating in R307-201-3 regarding Permitted Source
The following paragraph is no longer strictly relevant as noted under clarification.
However, it remains in the permit for historical reference.

Visible emissions: Visible emissions shall be no greater than 40% opacity from
installations constructed before April 25, 1971 and no greater than 20% opacity from
installations constructed after April 25, 1971. The source chooses to voluntarily accept a
20% opacity limit. Therefore, the most stringent limit of 20% opacity will be used for
source wide visible emissions. However, the 20% opacity limit will not apply to open
burn/open detonation of propellant, missiles and munitions, or missile testing, because
these operations are not considered an installation. [1/28/2003]

Clarification: The source-wide 20 percent opacity limit referred to above was removed in
the operating permit issued 2/10/2003. The only point sources subject to the opacity limit
Project OPP0112840014 Page 53 Title V Operating Permit #300036005

are the internal combustion engines, which have a unit-specific opacity limit in condition
II.B.4.b. The source-wide 20 percent opacity limit was removed in DAQE-
AN0112840021-10 for the same reason. [6/30/2009] [Last updated January 10, 2022]

8. Comment on an item originating in R307-221, 40 CFR 60 Subparts Cc and WWW, 40 CFR 62
Subpart OOO and 40 CFR 63 Subpart AAAA regarding #16: Oasis Landfill
40 CFR 60 Subpart Cc: Subpart Cc contains the requirements for state plan approval for
MSW landfills where construction, reconstruction, or modification was commenced before
May 30, 1991. Per R307-221, the requirements contained in the rule meet the requirements
in 40 CFR 60.30c through 60.36c of Subpart Cc and also meet the requirements in the state
plan for MSW landfills incorporated by reference in R307-220-2. Although the landfill
was previously subject to R307-221, it is now subject to 40 CFR 62 Subpart OOO which
implements the new federal plan for 40 CFR 60 Subpart Cf.

40 CFR 60 Subpart WWW: Per 40 CFR 60.750, the subpart applies to MSW landfills that
commenced construction, reconstruction, or modification on or after May 30, 1991, but
before July 18, 2014. The MSW landfill opened in 1978 with the design capacity of 70,000
short tons (63,503 megagrams (Mg)), which is well below the threshold design capacity of
2,755,750 tons (2.5 million Mg) contained in the subpart. Since the landfill does not meet
the date criteria for applicability, it is not subject to NSPS Subpart WWW.

40 CFR 63 Subpart AAAA: Per 40 CFR 63.1935, the subpart applies to MSW landfills
that accepted waste since 11/8/1987 and that are collocated with a major HAP source.
Landfill #16 meets that criteria and is existing, per 40 CFR 63.1940(c). It does not include
a bioreactor. The preamble for the final rule on page 2230 and 2231 of the 1/16/2003
federal register notice states:
"If a landfill is subject to the final rule because it is collocated with a major source and
the landfill has a design capacity less than 2.5 million Mg or 2.5 million m3, the
landfill must comply with the applicable EG/NSPS requirements (i.e., it must submit a
design capacity report). The landfill would not be subject to additional control and
reporting requirements under the NESHAP." (page 2230)
"Small landfills that are collocated with major source facilities are subject to the final
rule. The final rule requires them to comply with the EG/NSPS. If the design capacity
of the collocated landfills is less than 2.5 million Mg or 2.5 million m3, the landfills
comply by submitting a design capacity report as required by the EG/NSPS. The final
rule language has been revised to clarify that the final rule applies to these landfills but
does not extend the additional final rule requirements and EG/NSPS collection and
control requirements to landfills that do not meet the control device applicability
thresholds of the EG/NSPS." (page 2231)
Submittal of an initial design capacity report is the only applicable requirement from the
subpart. The permittee submitted the initial design capacity report on 9/14/2021.
Therefore, no requirements from subpart AAAA have been included in the permit.

40 CFR 62 Subpart OOO: Per 40 CFR 62.16711, the subpart applies to MSW landfills that
commenced construction, reconstruction, or modification on or before July 17, 2014, that
have accepted waste since 11/8/87, and that are not regulated by an EPA-approved state
plan implementing 40 CFR 60 Subpart Cf. The Oasis landfill meets that criteria. However
the subpart only requires an initial design capacity report for landfills with capacities less
than 2.5 million megagrams by mass or 2.5 million cubic meters by volume. The
permittee submitted the initial design capacity report required by 40 CFR 62.16714(d) on
8/30/2021. Only the requirements for an amended design capacity report have been
included in the permit should landfill capacity increase in the future.

9. Comment on an item originating in this permit regarding #6: Internal Combustion Sources
Consolidated emission unit: The emission unit description for #6: Internal Combustion
Sources has been modified to include all internal combustion sources. Emission units #6A
and 6B in the operating permit issued 7/30/2009 were deleted in the permit to avoid
redundancy. [3/24/2011] [Last updated January 10, 2022]

10. Comment on an item originating in 40 CFR 60 Subpart IIII regarding NSPS-CI-ICE: NSPS
Compression Ignition Internal Combustion Engines (CI ICE)
40 CFR 60 Subpart IIII definitions: 40 CFR 60 Subpart IIII defines emergency stationary
internal combustion engine as any stationary reciprocating internal combustion engine that
meets all of the criteria in paragraphs (1) through (3). All emergency stationary ICE must
comply with the requirements specified in 40 CFR 60.4211(f) in order to be considered
emergency stationary ICE. If the engine does not comply with the requirements specified
in 40 CFR 60.4211(f), then it is not considered to be an emergency stationary ICE under
40 CFR 60 Subpart IIII.
(1) The stationary ICE is operated to provide electrical power or mechanical work during
an emergency situation. Examples include stationary ICE used to produce power for
critical networks or equipment (including power supplied to portions of a facility)
when electric power from the local utility (or the normal power source, if the facility
runs on its own power production) is interrupted, or stationary ICE used to pump
water in the case of fire or flood, etc.
(2) The stationary ICE is operated under limited circumstances for situations not included
in paragraph (1), as specified in 40 CFR 60.4211(f).
(3) The stationary ICE operates as part of a financial arrangement with another entity in
situations not included in paragraph (1) only as allowed in 40 CFR 60.4211(f)(2)(ii)
or (iii) and 40 CFR 60.4211(f)(3)(i).

Certified emissions life means the period during which the engine is designed to properly
function in terms of reliability and fuel consumption, without being remanufactured,
specified as a number of hours of operation or calendar years, whichever comes first. The
values for certified emissions life for stationary CI ICE with a displacement of less than 10
liters per cylinder are given in 40 CFR 1039.101(g). The values for certified emissions life
for stationary CI ICE with a displacement of greater than or equal to 10 liters per cylinder
and less than 30 liters per cylinder are given in 40 CFR 1042.101(e).

Model Year means the calendar year in which an engine is manufactured (see 'date of
manufacture'), except as follows: (1) Model year means the annual new model production
period of the engine manufacturer in which an engine is manufactured (see 'date of
manufacture'), if the annual new model production period is different than the calendar
year and includes January 1 of the calendar year for which the model year is named. It may
not begin before January 2 of the previous calendar year and it must end by December 31
of the named calendar year. (2) For an engine that is converted to a stationary engine after
being placed into service as a nonroad or other nonstationary engine, model year means the
calendar year or new model production period in which the engine was manufactured (see
'date of manufacture').

Date of manufacture means one of the following things:
(1) For freshly manufactured engines and modified engines, date of manufacture means
the date the engine is originally produced.
(2) For reconstructed engines, date of manufacture means the date the engine was
originally produced, except as specified in paragraph (3) of this definition.
(3) Reconstructed engines are assigned a new date of manufacture if the fixed capital cost
of the new and refurbished components exceeds 75 percent of the fixed capital cost of
a comparable entirely new facility. An engine that is produced from a previously used
Project OPP0112840014 Page 55 Title V Operating Permit #300036005

engine block does not retain the date of manufacture of the engine in which the
engine block was previously used if the engine is produced using all new components
except for the engine block. In these cases, the date of manufacture is the date of
reconstruction or the date the new engine is produced.

Freshly manufactured engine means an engine that has not been placed into service. An
engine becomes freshly manufactured when it is originally produced.

Installed means the engine is placed and secured at the location where it is intended to be
operated.

None of the CI ICE engines at Hill UTTR have a displacement greater than 30 liters per
cylinder, there are no fire pump engines, and there will be no non-emergency engines
greater than 500 Hp. There are no pre-2007 engines, emergency or non-emergency, with a
displacement greater than or equal to 10 liters per cylinder and less than 30 liters per
cylinder that are affected units under 40 CFR 60 Subpart IIII.

The permittee has reviewed the ICE units throughout the base and determined they will not
be used for emergency demand response and/or voltage deviation purposes. For this
reason, language originating in 40 CFR 60.4211(f)(2)(ii)-(iii) has not been included in the
permit.

Tad –

The informaon you have requested is provided below:

In reviewing the existing UTTR permit I notice that fugitives have not been separated from point sources (PM10, PM2.5 and NOx). It is not a
requirement, I am just wondering if you wanted to separate out the fugitives from the point sources at this point in time. Please leave as is and we canaddress in a future permit modificaon, if needed.

I was wondering if you have a quick and easy CO2e emissions number. It has not been included in the existing permit and would get flagged if I
tried to pass it through management without.
Generators:
CO2: 2,543 tpy
N2O: 1.90E-02 tpy
CH4: 0.12 tpy
UTTR total (from most recent TVOP renewal applicaon):
CO2: 5,330 metric tpy

Attention: NSR
P.O. Box 144820
Salt Lake City Utah 84114-4820

Dear Director

Hill Air Force Base (AFB) is submitting this notice of intent (NOI) for the addition of
one diesel-fired generator. A redline of approval order (AO) DAQE-AN112840026-17, for the
Utah Test and Training Range (UTTR), with the requested changes in this NOI is included as
Attachment 1. The new generator will have the following specifications:

Equipment type: Compression ignition internal combustion engine
Manufacturer: Caterpillar
Model: C18
Fuel: Diesel
Engine rating: 528 kW
Model year: 2024
Tier rating: 4

The new generator will be subject to the 225,000-gallon annual fuel limit for diesel-fired
generators. Potential to emit (PTE) emissions for diesel-fired generators are based on the annual
fuel limit. Since there is not a request to increase the annual diesel fuel limit, the addition of the
new generator will not result in a change to the PTE emissions for diesel-fired generators.
The changes proposed in this NOI do not result in a major modification. Therefore, the
requirements of Utah Administrative Code R307-403, R307-405, R307-406 and R307-420 do
not apply. Criteria pollutant modeling is not required because there are no emission increases. A
screening analysis for hazardous air pollutants is not required as there are no emission increases.

The engine is subject to New Source Performance Standards 40 CFR 60 Subpart IIII,
‘Standards of Performance for Stationary Compression Ignition Internal Combustion Engines’
and is also affected sources under National Emission Standards for Hazardous Air Pollutants 40
CFR 60 Subpart ZZZZ, ‘Stationary Reciprocating Internal Combustion Engines, but there are no
applicable emission limits. The unit will comply with all applicable requirements of the Hill
AFB UTTR Title V Operating Permit (TVOP) Conditions II.B.4.b, II.B.4.c, II.B.7 and II.B.9.
Best available control technology (BACT) for internal combustion engines is provided in TVOP

Conditions II.B.4.b, II.B.4.c, II.B.7 and II.B.9 and a BACT determination is included as
Attachment 2.

Hill AFB requests the enhanced new source review process for this AO so the UTTR
TVOP can be modified administratively. If you have any questions or would like to discuss this
issue further, my point of contact is Dr. Erik Dettenmaier 75 CEG/CEIEA, at [phone] or
[e-mail].

Abstract
Hill Air Force Base (Hill) has requested to modify their current AO DAQE-AN1128400265-175 to update language and add one diesel-fired generator equipment. Hill performs Open Detonation (OD) and Open Burning (OB) operations at the Thermal Treatment Unit located at Hill's Utah Test and Training Range (UTTR). Hill has requested to update monitoring and recordkeeping requirements to make the UTTR permit language consistent with the language for the Main Base permits. Hill has also requested to add two (2) diesel-fired emergency generators. The additional two generators will be operated under the existing diesel fuel permit limit. By operating under an existing limit only actual emissions will go up, and potential emissions will be unchanged.
The UTTR site is located in the areas of Box Elder and Tooele Counties that are in attainment of the
NAAQS for all pollutants. The UTTR site is a major HAP source, a Title V major source subject to 40 CFR 60, Subpart A and IIII and 40 CFR 63 Subpart A and ZZZZ. Title V of the 1990 CAA applies to this source. This is an enhanced AO and the Title V operating permit will be administratively amended. The UTTR site wide emissions will remain as follows (TPY): PM10 =241.25, PM2.5 (PM2.5 is a subset of PM10) = 241.25, SOX= 4.47, NOX = 111.27, CO = 39.87, VOC = 14.75 and HAPs = 315.46.
This air quality AO authorizes the project with the following conditions and failure to comply with any of the conditions may constitute a violation of this order. This AO is issued to, and applies to the following:
Name of Permittee:
Hill Air Force Base 75 CEG/CEIE 7290 Weiner Street Hill Air Force Base, UT 84056-5003

If a propellant or a munition that is not a Hazardous Class 1.1, 1.3 or 1.4 is to be detonated or burned, prior approval must be obtained from the Director.
Reporting:
Records required for this permit condition shall be submitted to UDAQ by February 28 of each year for the preceding year. [R307-401]
II.B.2.b Hill shall use the most current sound focusing mitigation plan (SFMP) for all detonations greater than or equal to 10,000 lbs NEW at the TTU area. The SFMP shall be dated March 29, 2012 or later. The plan shall outline the procedures that will be used for each detonation that will minimize the effects of over pressure on large populations of people located in Tooele, Grantsville, and Wasatch Front Cities. The plan shall contain specific criteria that will be used to decide whether or not to detonate. If the plan proves inadequate to predict adverse focus conditions in areas off of UTTR property, i.e., there are complaints of excessive focusing of noise, the detonation operation may, at the request of the Director, be restricted or suspended until the incident(s) can be fully investigated by Hill and potential corrective actions identified.
Corrective actions may include reduction of limits and/or adjustments to operational
procedures, focusing criteria or sound modeling algorithms. In addition, the SFMP may be
modified. Hill shall make the results of investigations into excessive sound events and all
corrective actions available to the Director within 15 business days of the completion of an

the state of Utah that is within 70 miles of the TTU, Hill shall submit a plan outlining the
procedures that they will follow during the emergency episode. The plan shall identify what
control/production measures Hill shall implement when an emergency episode is declared by the Executive Director of the Department of Environmental Quality that is within 50 miles of the TTU. Specific emission reduction measures shall be outlined in the plan for three levels (Alert, Warning, Emergency). The emergency plan shall be approved by the Director. The Alert Level actions to be taken should be curtailment of all unnecessary activities causing air pollution. The other two levels of actions should be a progressive curtailment of production and activities causing pollution, to the point of a complete shutdown of operation. [R307-401]
II.B.3 OB/OD
II.B.3.a Hill is not allowed the open burning of any waste containing beryllium or other highly toxic materials except when meteorological conditions are such that the resulting products of combustion will traverse over unoccupied areas only. A description and evaluation of the quantities of highly toxic material to be emitted to the atmosphere must be submitted to the Director prior to each burning.
Reporting:
Records required for this permit condition shall be submitted to UDAQ by February 28 of each year for the preceding year. [R307-401]

Attachment 2: BACT Determination
To evaluate the appropriate best available control technology (BACT) for the proposed
diesel-fired engine, the Environmental Protection Agency (EPA)’s Reasonably Available Control
Technology (RACT)-BACT-Lowest Achievable Emission Rate (LAER) Clearinghouse (RBLC)
was reviewed. The RBCL provides listings of emission control determinations made by state
and local air pollution control agencies as well as the regional EPA offices and includes control
technologies and/or work practices that may be suitable for each process type code. In addition
to the RBLC, other sources including control equipment vendors, published literature and
previous Utah Division of Air Quality BACT determinations for diesel-fired generators were
reviewed. The following is a list of control technologies identified.
1) EPA’s RBLC was reviewed to determine EPA BACT decisions for diesel-fired internal
combustion compression ignition engines with size ratings near the new engine rating of
528 kW (process type code 17.110). These BACT determinations are summarized in the
following table.
RBCL
ID
Unit Size
(kW) NOX Control Determination
LA-0364 410 kW
Compliance with the limitations imposed by 40 CFR 63 Subpart IIII
and operating the engine in accordance with the engine manufacturer's
instructions and/or written procedures designed to maximize
combustion efficiency and minimize fuel usage
IN-0371 500 kW Good combustion practices and compliance with NSPS 40 CFR 60
Subpart IIII
LA-0394 500 kW Good combustion practices and compliance with NSPS 40 CFR 60
Subpart IIII
KY-0110 522 kW Good combustion and operating practices plan
KY-0115 522 kW Good combustion and operating practices plan
MN-0095 576 kW Emergency classification, hourly restriction, ultra-low sulfur diesel
fuel, good combustion practices, and NSPS compliance
LA-0390 686 kW Good combustion and operating practices plan
IN-0371 1,000 kW Good combustion practices and meeting NSPS Subpart IIII
requirements

2) Good Combustion Practices: Includes official documentation and training in operating
and maintenance procedure, including procedures for startup, shutdown and malfunction;
routine inspection and preventative maintenance procedures; equipment overhaul and
include recordkeeping of operating logs and maintenance records. Good combustion
practices reduce emissions of all criteria pollutants.

3) Use of Low-Sulfur Fuel (0.05%): Use of low-sulfur diesel fuel reduces SOX emissions
and is considered BACT for diesel-fired engines.

4) 40 CFR Part 60 Subpart IIII 'Standards of Performance for Stationary Compression
Ignition Internal Combustion Engines' requires owners and operators of non-emergency
Attachment 2: BACT Determination
and emergency affected engines to comply with emission standards (Tier standards)
based on engine model year, maximum engine power, engine displacement and use
(emergency, non-emergency). The Tier standards are emission limits for PM, CO and
NMHC + NOx or NOx and NMHC. The subpart requires proper operation and
maintenance, in accordance with the manufacturer, to ensure affected emission units
achieve the applicable Tier standards over the entire life of the engine. The subpart
requires affected emission units with a displacement of less than 30 liters per cylinder to
comply with fuel sulfur limitations: (1) fuel sulfur content no greater than 15 ppm
(0.0015 percent) by weight and (2) a minimum cetane index of 40 or a maximum
aromatic content of 35 volume percent.

5) Limited Hours of Operation: 40 CFR Part 60 Subpart IIII 'Standards of Performance for
Stationary Compression Ignition Internal Combustion Engines' limits the operation for
readiness (maintenance and testing) to 100 hours annually for generators. Limiting the
hours of operation for the equipment limits emissions of all pollutants released from the
generator.

6) 40 CFR Part 63 Subpart ZZZZ 'National Emission Standards for Hazardous Air
Pollutants for Stationary Reciprocating Internal Combustion Engines' requires owners
and operators of non-emergency and emergency affected engines to at all times operate
and maintain any affected source in a manner consistent with safety and good air
pollution control practices for minimizing emissions.

7) Selective Catalyst Reduction (SCR): Is a combination of engineered components
designed to reduce the amount of NOx in a turbine or engine exhaust stream. A form of
ammonia is injected in front of a catalyst to reduce the NOx. Nitrogen oxides are formed
when the oxygen and nitrogen in the air react with each other during combustion. High
temperatures and excess oxygen (more than is needed to burn the fuel) favor the
formation of nitrogen oxides. SCR systems are installed to reduce NOx levels in the
exhaust gas stream from the engine. SCR systems have the capability of reducing both
NO and NO2 in the gas stream by injecting an ammonia reagent ahead of the catalyst. In
addition to NOx control, SCR systems with an oxidation catalyst can also reduce CO
emissions.
For SCR systems to function effectively, exhaust temperatures must be high enough (200°C to 500°C) to enable catalyst activation. SCR control efficiencies are relatively low during the first 20 to 30 minutes after engine start up, especially during maintenance and testing. There are also complications controlling the excess ammonia (ammonia slip) from SCR use. SCR is anticipated to have relatively low combustion efficiency during
maintenance and testing.
Attachment 2: BACT Determination
All of the technologies listed above for control of emissions from diesel-fired generators are
technically feasible. Based on the review of control technologies considered BACT for diesel-
fired engines, Hill AFB has determined the following meets BACT requirements:
• Good combustion, maintenance and operating practices
• Use of low-sulfur diesel fuel
• Compliance with applicable NSPS IIII requirements
o Use of a tier certified engine
o Limit on hours of operation for maintenance and testing operations
• Compliance with applicable NESHAP ZZZZ requirements
Additionally, the generator will be turbocharged air-to-air aftercooled and will be equipped
with a diesel particulate filter and an aftertreatment system. The primary function of the
aftertreatment system is to reduce the undesirable exhaust emissions. Through this process, NOX
reacts with diesel exhaust fluid across catalysts within the clean emission module (CEM) and
gets converted into nitrogen and water before releasing them into the atmosphere. The CEM
includes diesel oxidation catalyst and selective catalytic reduction.
