General Description
This AO is issued to Whitaker Construction for the purpose of operating a portable source that belongs to
the nonmetallic mineral processing industry, including aggregate, concrete, and hot mix asphalt plants.
The plants subject to this AO shall be temporarily operated for a period of not more than 180 working
days at any location. A relocation shall not exceed 365 consecutive days at any location in the State of
Utah.

Prior to commencement of operation at a location, the owner/operator shall submit a Notice of Temporary
Relocation to the Director and obtain a Temporary Relocation Approval Letter. If the owner/operator
operates at a location in compliance with the AO, the Notice of Temporary Relocation, and the
Temporary Relocation Approval Letter, dispersion modeling results have determined that there will be no
adverse impacts on air quality at the nearest residence or commercial establishment.

Compliance with the opacity limits and operating practices contained in the conditions of the AO shall be
considered an application of BACT. The emission control measures required in the conditions of this AO
shall apply to all of the locations at which the source approved by this AO operates. The source may be
required to adopt additional measures for controlling emissions to address location-specific concerns.

This AO limits the source to emissions that are below the major source threshold, making it a "Synthetic
Minor" source.

General Description
This AO is issued to Whitaker Construction Company, Inc. (Whitaker Construction) for the purpose of
operating a portable source that belongs to the nonmetallic mineral processing industry, including
aggregate, concrete, and hot mix asphalt plants. The plants subject to this AO shall be temporarily
operated for a period of not more than 180 working days at any location. A relocation shall not exceed
365 consecutive days at any location in the State of Utah.

Prior to commencement of operation at a location, the owner/operator shall submit a Notice of Temporary
Relocation to the Director and obtain a Temporary Relocation Approval Letter. If the owner/operator
operates at a location in compliance with the AO, the Notice of Temporary Relocation, and the
Temporary Relocation Approval Letter, dispersion modeling results have determined that there will be no
adverse impacts on air quality at the nearest residence or commercial establishment.

Compliance with the opacity limits and operating practices contained in the conditions of the AO shall be
considered an application of BACT. The emission control measures required in the conditions of this AO
shall apply to all of the locations at which the source approved by this AO operates. The source may be
required to adopt additional measures for controlling emissions to address location-specific concerns.

This AO limits the source to emissions that are below the major source threshold, making it a "Synthetic
Minor" source.

EMISSION IMPACT ANALYSIS DAQ modeled a generic aggregate site to determine the appropriate operating conditions for this AO. Ambient
air quality impacts are smaller in the daytime hours than in the nighttime hours. To minimize impacts, the times of operation were limited. Sources will be allowed to operate from 6:00 am to 10:00 pm. A permit condition is included in this AO to reflect the time restriction of operation. More stringent times of operation
may be included in different areas of the State. If a source wants to operate outside these times, the source must submit modeling with the temporary relocation letter to demonstrate that the NAAQS are met. [Last updated August 23, 2024]

The process equipment for this portable source includes the following: A. Aggregate Equipment (Crushers, Screens, Conveyors)
B. Concrete Batch Plants C. Hot Mix Asphalt Plants D. Stationary Diesel-Fired Engines
A. Aggregate Equipment (Crushers, Screens, Conveyor Transfer Points)
The following opacity limitations shall not be exceeded for the following aggregate equipment: Crushers - 12% Screens - 7% Conveyor Transfer Points - 7%
Feeders - 7% Stackers - 7% Water sprays will control the emissions from crushers, screens, conveyors, feeders, and stackers.
Sprays will operate as needed to comply with the above opacity limits. B. Concrete Batch Plants
Fabric filters will control the emissions from concrete batch plants, the batching operations, and
associated silos. The fabric filters will reduce visible emissions to 7% opacity or less. Any boiler/water heater used will use natural gas and/or propane as fuel. Any boiler/water heater shall be limited to 10% opacity.
C. Hot Mix Asphalt Plants
The hot mix asphalt plants may use propane, natural gas, fuel oil, on-specification used oil or any combination of these fuels as fuel. A baghouse will control the emissions from the drum mixer. The baghouse will reduce visible emissions to 10% opacity or less. In addition, the baghouse will reduce the concentration of PM10 in the exhaust to 0.024 grains per dscf or less. To ensure the baghouse is operating correctly, the baghouse pressure drop shall be between 3 and 7 inches of water column. The pressure gauge shall measure the pressure drop in 1-inch water column increments or less. D. Stationary Diesel-Fired Engines The NSR Section recommends the following as BACT for stationary diesel engines: 1. Proper engine tuning and maintenance
2. Visible emissions shall be 20% opacity or less 3. Sulfur content of fuel shall be 15 ppm or less 4. Compliance with the applicable federal standards contained in

REVIEWER COMMENTS

1. Comment regarding Modification to DAQE-AN014318002-11: Whitaker Construction has requested a modification to Approval Order (AO) DAQE-AN0143180002-11. DAQE-AN0143180002-11 was an outdated portable AO which had conditions
requiring specific equipment, storage pile size, etc. The source has requested that DAQE-AN0143180002-11 be modified to the current generic portable AO format. [Last updated September 6, 2024]
2. Comment regarding NSPS and MACT Applicability: This equipment is subject to 40 CFR 63 (MACT) Subpart ZZZZ and 40 CFR 60 (NSPS) Subparts IIII, I, and OOO. 40 CFR 60 Subpart IIII applies to" owner and operators of stationary CI ICE that commence construction after July 11, 2005". This source operates a stationary CI ICE manufactured after 2005. Therefore, Subpart IIII applies to this source.
40 CFR 63 Subpart ZZZZ applies to owners and operators of a RICE at any area source of HAP
emissions. Because this source operates a RICE at a site(s) that are considered area sources, Subpart ZZZZ applies to this source. 40 CFR 60 Subpart I applies to sources who operate hot mix asphalt facilities constructed after June 11, 1973. If this source operates a hot mix asphalt facility using this portable AO, NSPS Subpart I will apply to this source.
40 CFR 60 Subpart OOO applies to each crusher, screening operation, and belt conveyor in fixed or
portable nonmetallic mineral processing plant manufactured after August 31 1983. If this source shall decide to operate any of this equipment using this portable AO, Subpart OOO will apply to this source. [Last updated August 23, 2024]

5. Comment regarding Reporting: R307-401-17 requires that "records of the working days at each site, consecutive days at each site, and actual production rate shall be submitted to the director at the end of each 180 calendar days." The owner/operator must submit this information to be in compliance with R307-401-17.
[Last updated August 23, 2024] 6. Comment regarding Hot Mix Asphalt Plant Condensable PM Emissions:
Condensable PM emissions shall not be used for compliance demonstration during stack testing; however, condensable PM emissions shall be used for inventory purposes. There are several reasons condensable PM emissions will not be used for compliance demonstration.
A. NSPS Subpart I does not limit condensable PM emissions. DAQ is unaware of any other regulation that limits PM emissions, including condensable PM emissions, from hot mix asphalt plants. Since federal regulations only limit filterable PM emissions, only filterable PM emissions will be used for compliance demonstration.
B. The control device used to control PM emissions from a hot mix asphalt plant is a baghouse. A baghouse is unable to control condensable PM emissions from a hot mix asphalt plant. One of the
purposes of a stack test is to ensure the control device is operating correctly. Since the baghouse can only control filterable PM emissions, only filterable PM emissions will be used for compliance

Engineer Review N143180003: Whitaker Construction Company, Inc.- Portable Aggregate and Concrete Equipment September 6, 2024 Page 19
demonstration. C. The majority of uncontrolled emissions from a hot mix asphalt plant is filterable emissions. Based on AP-42, an uncontrolled 400 tph hot mix asphalt plant will emit 11,200 pounds of filterable PM per hour and 7.8 pounds of condensable PM per hour. The amount of uncontrolled filterable PM emissions is over 1,400 times higher than the condensable PM emissions. Since the uncontrolled filterable PM emissions are so high, only filterable PM emissions will be tested for compliance demonstration. D. Condensable PM emissions can vary depending on the fuel being combusted, the burner, the
material being fed into the hot mix asphalt plant, and other factors. It is inappropriate to put a single limit in a permit that could apply to different locations, different plants, different materials, and different fuels. Due to the high variability of these factors, condensable emissions will not be used for compliance demonstration for this portable source. Due to the reasons above, condensable PM emissions will not be tested for compliance demonstration; however, condensable PM emissions will be used for inventory purposes. The Director may require an emissions inventory at any time according to R307-150-1(4). Because this
source is a Title V area source, this source is required to pay Title V fees according to R307-415-9. Both filterable and condensable PM emissions are considered chargeable pollutants; therefore, the owner/operator must test for condensable PM emissions for inventory purposes. [Last updated August 23, 2024] 7. Comment regarding Definition of Stationary Engines: The definition of stationary internal combustion engine in NSPS Subpart IIII (40 CFR 60.4219) is as follows: Stationary internal combustion engine means any internal combustion engine, except combustion turbines, that converts heat energy into mechanical work and is not mobile. Stationary ICE differ from mobile ICE in that a stationary internal combustion engine is not a nonroad engine as defined
at 40 CFR 1068.30 (excluding paragraph (2)(ii) of that definition), and is not used to propel a motor vehicle, aircraft, or a vehicle used solely for competition. Stationary ICE include reciprocating ICE, rotary ICE, and other ICE, except combustion turbines.
The definition of nonroad engine in 40 CFR 1068.30 is as follows: Nonroad engine means: (1) Except as discussed in paragraph (2) of this definition, a nonroad engine is an internal combustion engine that meets any of the following criteria: (i) It is (or will be) used in or on a piece of equipment that is self-propelled or serves a dual purpose by both propelling itself and performing another function (such as garden tractors, off-highway
mobile cranes and bulldozers). (ii) It is (or will be) used in or on a piece of equipment that is intended to be propelled while performing its function (such as lawnmowers and string trimmers). (iii) By itself or in or on a piece of equipment, it is portable or transportable, meaning designed to be and capable of being carried or moved from one location to another. Indicia of transportability include, but are not limited to, wheels, skids, carrying handles, dolly, trailer, or platform.
(2) An internal combustion engine is not a nonroad engine if it meets any of the following criteria:

Engineer Review N143180003: Whitaker Construction Company, Inc.- Portable Aggregate and Concrete Equipment September 6, 2024 Page 20
(i) The engine is used to propel a motor vehicle, an aircraft, or equipment used solely for competition. (ii) The engine is regulated under 40 CFR part 60, (or otherwise regulated by a federal New Source Performance Standard promulgated under section 111 of the Clean Air Act (42 U.S.C. 7411)). Note that this criterion does not apply for engines meeting any of the criteria of paragraph (1) of this
definition that are voluntarily certified under 40 CFR part 60. (iii) The engine otherwise included in paragraph (1)(iii) of this definition remains or will remain at a location for more than 12 consecutive months or a shorter period of time for an engine located at a seasonal source. A location is any single site at a building, structure, facility, or installation. For any
engine (or engines) that replaces an engine at a location and that is intended to perform the same or similar function as the engine replaced, include the time period of both engines in calculating the consecutive time period. An engine located at a seasonal source is an engine that remains at a
seasonal source during the full annual operating period of the seasonal source. A seasonal source is a stationary source that remains in a single location on a permanent basis (i.e., at least two years) and that operates at that single location approximately three months (or more) each year. See §1068.31
for provisions that apply if the engine is removed from the location. [Last updated August 23, 2024] 8. Comment regarding Definition of Stationary Engines (Cont'd): 40 CFR 1068.31 has the following requirements: (b) A stationary engine becomes a new nonroad engine if- (1) It is used in an application that meets the criteria specified in paragraphs (1)(i) or (ii) in the definition of "nonroad engine" in §1068.30. (2) It meets the criteria specified in paragraph (1)(iii) of the definition of "nonroad engine" in §1068.30 and is moved so that it fails to meet (or no longer meets) the criteria specified in paragraph
(2)(iii) in the definition of "nonroad engine" in §1068.30. (c) A stationary engine does not become a new nonroad engine if it is moved but continues to meet the criteria specified in paragraph (2)(iii) in the definition of "nonroad engine" in §1068.30 in its new location. For example, a transportable engine that is used in a single specific location for 18 months
and is later moved to a second specific location where it will remain for at least 12 months is considered to be a stationary engine in both locations. Note that for stationary engines that are neither portable nor transportable in actual use, the residence-time restrictions in the definition of
"nonroad engine" generally do not apply. (e) A nonroad engine ceases to be a nonroad engine and becomes a new stationary engine if-
(1) At any time, it meets the criteria specified in paragraph (2)(iii) in the definition of "nonroad
engine" in §1068.30. For example, a portable generator engine ceases to be a nonroad engine if it is used or will be used in a single specific location for 12 months or longer. If we determine that an engine will be or has been used in a single specific location for 12 months or longer, it ceased to be a
nonroad engine when it was placed in that location. (2) It is otherwise regulated by a federal New Source Performance Standard promulgated under section 111 of the Clean Air Act (42 U.S.C. 7411). [Last updated August 23, 2024]

Thank you for your assistance in the emissions permitting process as Whitaker Construction prepares to move forward
with the DFCM project to expand the Bear Lake Marina. Attached are the completed forms 15b and 15c. Will you get
these to the appropriate people at DAQ? Also, please advise on next steps.

Whitaker Construction already has a portable AO, so you'll need to modify that AO.

Hi Shane,
After searching DAQ records, it was determined that Whitaker Construction already has a portable Approval Order (AO)
with the DAQ that was issued in 2011. I have attached the portable AO for your reference.
The 2011 AO states in condition II.B.1.b that "Equipment listed in this AO can be replaced by other equipment of equal or
lesser production capacity having the same function as the existing equipment with written notification to the Director, and
adherence to the DAQ 'Replacement in Kind'." The equipment you have listed in Form 15b is all of lesser or equal
rating/production capacity as the equipment in the 2011 AO. So, with your concurrence, I can replace some of the old
equipment with the new equipment you are planning to use for the project in the permit.
This replacement would be classified as an Administrative Amendment and would not need to go through the 30-day
public comment period. Once the Amendment is approved you would be able to submit a temporary relocation for the
Bear Lake Marina project using this updated portable AO. Taking this approach will save you time and money, but you
would be required to meet the remaining requirements in the 2011 AO -- this includes not exceeding 2,880 hours of total
operation, a maximum storage pile size of 1.5 acres, and a maximum disturbed ground size of 5.0 acres.
Please take a look at the attached document and make sure that your project is able to meet the outlined requirements. If
you are able to meet the requirements, please confirm that you want to move forward with updating your existing 2011
portable AO.
Let me know if you have any questions.
Thanks,
Dungan

Shane,
If you don't feel comfortable staying under the 5 acres of disturbed ground then I can't do the 'replacement in kind'
equipment change I outlined in the previous email. I can modify the entire 2011 portable AO to the current generic format
which gives you a lot more flexibility (and keeps you from having two portable AOs). However, this will be classified as a
permit modification and will go through the 30-day public comment period.
Let me know how you would like me to proceed and I will move this along as quickly as I can.
Thanks,
Dungan

Thanks for confirming. There are a several contacts listed throughout forms 15b and 15c, so I wanted to confirm who the
primary Approval Order (AO) contact and billing contact should be. The primary AO contact will have their name on the
portable AO and receive the approved permit. The billing contact will receive the invoice for this project.
Please advise who the AO contact and billing contact to should be. If their contact information has not been previously

Good morning Rhett,
Attached is the draft portable Approval Order for you to review. Please look over the attached document and let me know
if you have any questions or concerns. I have left in the standard hot-mix asphalt sections to allow for future flexibility. If
Whitaker Construction never does any hot-mix asphalt projects, conditions II.B.9 - II.B.11.b.4 won't ever apply-- but by
leaving them in you have the ability to do these projects without needing to modify your Approval Order.
If everything looks good, please sign the cover page and return it to me. Once I have your concurrence, I will get the
project processed and it will enter the 30-day public comment period.
Thanks,
Dungan
