Project Description
Whitaker has requested a modification to its AO DAQE-AN132830006-20, dated January 24, 2020, to
increase operating hours to 6:00 AM to 12:00 AM from November 1st through March 31st and to
increase storage pile size from three (3) to nine (9) acres.

Whitaker does not propose to raise its annual production; therefore, there will be no emission changes
from the aggregate processing operations except for the increase in the storage pile size. Emission
increases due to the increase in the storage pile size are estimated, and the site-wide emissions are
updated.

SOURCE DESCRIPTION General Description
Whitaker Construction Company, Inc. (Whitaker) operates the Plymouth Aggregate Plant in Box Elder County. The equipment onsite includes crushers, screens, conveyors, feeders, and mobile equipment such as loaders, haul trucks, and water trucks. Line power is used to operate the
equipment on site. Whitaker produces up to 550,000 tons of aggregate material per year. NSR Classification: Minor Modification at Minor Source Source Classification Located in Salt Lake City UT PM2.5 NAA Box Elder County Airs Source Size: B Applicable Federal Standards

Project Proposal Modification to AO DAQE-AN132830006-20 to Increase Hours of Operation and Storage Pile
Size Project Description Whitaker has requested a modification to its AO DAQE-AN132830006-20, dated January 24, 2020, to increase operating hours to 6:00 AM to 12:00 AM from November 1 through March 31 and to increase storage pile size from 3 to 9 acres.
Whitaker does not propose to raise its annual production; therefore, there will be no emission changes from the aggregate processing operations except for the increase in the storage pile size. Emission increases due to the increase in the storage pile size are estimated and the site-wide emissions are updated. EMISSION IMPACT ANALYSIS The source's PM10 and PM2.5 emission increases are below the threshold for modeling in UAC Code R307-410-4. The source has not proposed any HAP emission increases. However, the source has requested to increase their winter (November through March) hours of operation from 6:00 am to 6:00 pm to 6:00 am to 12:00 am. The original winter operation limit was implemented due to emission impact analysis. The DAQ conducted 24-hour PM10 analysis. The results indicate the highest PM10 impact would be 92.6% of the NAAQS levels.
Based off the results of emission impact analysis, the source shall not operate the aggregate plant or any hauling activities from 12:00 am to 6:00 am from November through March. See Modeling Memorandum DAQE-MN132830007-24, dated November 13, 2024, for additional details [Last updated November 27, 2024]

Engineer Review N132830007: Whitaker Construction Company, Inc. - Plymouth Aggregate Plant November 27, 2024 Page 4
Review of BACT for New/Modified Emission Units 1. BACT review regarding Storage Pile Size
Whitaker has requested to increase storage pile size from 3 acres to 9 acres. Storage piles produce PM10 and PM2.5 emissions. Possible control options for particulate emissions from storage piles include: full enclosures, partial enclosures, and water sprays. Because of the large acreage of
storage piles spread across the property, full and partial enclosures are not considered economically feasible. BACT for storage piles is the use of water sprays to maintain visible opacity below 20%. [Last updated October 25, 2024] 2. BACT review regarding Operation Hours The emissions from all other operations will remain the same. Whitaker does not propose any change to its equipment or its annual production. Therefore, BACT is not required for the change of operating hours. [Last updated November 27, 2024]

PERMIT HISTORY When issued, the approval order shall supersede (if a modification) or will be based on the
following documents: Supersedes DAQE-AN132830006-20 dated January 24, 2020
Is Derived From NOI dated October 21, 2024 Incorporates Additional Information dated October 31, 2024
REVIEWER COMMENTS 1. Comment regarding Emission Increases: Storage pile emissions increases are calculated using AP-42 Appendix B.2 Tables B.2-2 & B.2-3 and AP-42 Fourth Edition Table 8.19.1-1. The original three (3) acres of storage piles are calculated to produce 1.17 tons per year (TPY) of PM10 and 0.61 TPY of PM2.5. The updated nine (9) acres of storage piles are calculated to produce 3.52 TPY of PM10 and 1.82 TPY of PM2.5. The increase of six (6) acres of storage piles will increase PM10 emissions by 2.35 TPY and PM2.5 emissions by 1.22 TPY. The previous Approval Order (AO) did not include any recordkeeping or reporting requirements for storage pile size. These requirements have been added to the AO. [Last updated November 4, 2024]
2. Comment regarding Federal Subpart Applicability: NSPS 40 CFR Part 60 Subpart OOO (Standards of Performance for Nonmetallic Mineral Processing Plants) applies to select equipment at nonmetallic mineral processing plants that commenced construction, modification, or reconstruction after August 31, 1983. The screens, crushers, and transfer/drop points (conveyors, stackers, feed bins) at this facility are subject to 40 CFR Part 60 Subpart OOO. [Last updated October 25, 2024]
3. Comment regarding Title V Applicability: Title V of the 1990 Clean Air Act (Title V) applies to the following:
1. Any major source 2. Any source subject to a standard, limitation, or other requirement under Section 111 of the Act, Standards of Performance for New Stationary Sources; 3. Any source subject to a standard or other requirement under Section 112 of the Act, Hazardous Air Pollutants. 4. Any Title IV affected source. This facility is not a major source and is not a Title IV source. This facility is subject to 40 CFR 60 (NSPS Subpart OOO) regulations that do not specifically exempt it from Title V. Therefore, Title V applies to this facility as an area source. [Last updated October 25, 2024]

SUBJECT: Modeling Analysis Review for the Notice of Intent for Whitaker Construction Company
– Plymouth Aggregate Plant, Box Elder County, Utah
_____________________________________________________________________________________
This is not a Major Prevention of Significant Deterioration (PSD) Source.
I. OBJECTIVE
Whitaker Construction Company (Applicant) is seeking an approval order for their Plymouth
Aggregate Plant located in Box Elder County, Utah.

This report, prepared by the Staff of the New Source Review Section (NSR), contains a review of
the air quality impact analysis (AQIA) including the information, data, assumptions and modeling
results used to determine if the facility will be in compliance with applicable State and Federal
concentration standards.

II. APPLICABLE RULE(S)
Utah Air Quality Rules:

R307-401-6 Condition for Issuing an Approval Order
R307-410-3 Use of Dispersion Models
R307-410-4 Modeling of Criteria Pollutants in Attainment Areas
III. MODELING METHODOLOGY

A. Applicability

Emissions from the facility include PM10, NOx, CO, SO2, and HAPs. This modeling is part of a modified approval order. The emission rates for PM10 triggered the requirement to model
under R307-410. Modeling was performed by the Applicant.

B. Assumptions

1. Topography/Terrain

The Plant is at an elevation 4600 feet with terrain features that have an affect on
concentration predictions.

a. Zone: 12
b. Approximate Location:
UTM (NAD83): 403219 meters East
4638685 meters North
2. Urban or Rural Area Designation
After a review of the appropriate 7.5 minute quadrangles, it was concluded the area is “rural” for air modeling purposes.
3. Ambient Air
It was determined the Plant boundary used in the AQIA meets the State’s definition of
ambient air.
4. Building Downwash
The source was modeled with the AERMOD model. All structures at the plant were used in the model to account for their influence on downwash.
5. Meteorology

Five (5) years of off-site surface and upper air data were used in the analysis consisting of
the following:
Surface – Nucor Steel: 2008
Upper Air – Salt Lake Airport NWS: 2008

6. Background

The background concentrations were based on concentrations measured in Ogden, Utah.
7. Receptor and Terrain Elevations

The modeling domain used by the Applicant consisted of receptors including property
boundary receptors. This area of the state contains mountainous terrain and the modeling
domain has simple and complex terrain features in the near and far fields. Therefore,
receptor points representing actual terrain elevations from the area were used in the
analysis.

DAQE- MN132830007-24

8. Model and Options

The State-accepted AERMOD model was used to predict air pollutant concentrations under
a simple/complex terrain/wake effect situation. In quantifying concentrations, the
regulatory default option was selected.

Hi Scott,
The Utah Division of Air Quality (DAQ) is currently reviewing the modeling files for this project, thanks for sending those
over so quickly.
The only minor concern I have with the NOI is the emission calculations for storage piles. I compared the calculations in
the NOI with the DAQ storage pile spreadsheet and there are some slight differences. The NOI states that watering is
50% control per DAQ and PM2.5 emission factor is 7.5% of PM10 per DAQ. Can you tell me where you are getting this
information?
I am thinking these calculations might be outdated and have not used either of these factors during my time with the DAQ.
The control efficiency for watering we currently use for storage piles is 66% for PM10 and 40% for PM2.5 (AP-42
Appendix B.2 Table B.2-2 and Table B.2-3). The calculation for the PM2.5 emission factor is also a bit more involved than
7.5% of the PM10 factor.
I have attached the DAQ's storage pile spreadsheet. I think the easiest way to move forward is to confirm that the source
is adding 6 acres of storage piles and use the attached spreadsheet for those calculations. Let me know what you think.
Thanks,
Dungan

Hi Dungan,
I have updated the emission calculaons (aached) based on the UDAQ storage pile calculaon sheet for
your convenience. As you will see in the aached spreadsheet, the projected PM10 emissions are lower
using the UDAQ provided spreadsheet and PM2.5 emissions are slightly higher. Since modeling was
performed for PM10 only, the emission rates used in the modeling are more conservave than are reflected
in the aached spreadsheet. The emission factors Trinity used in the NOI for storage piles have been
accepted by the UDAQ for several recent projects. As I recall, the control factors were provided around
2014-2015 by UDAQ engineers who have subsequently rered or have le the agency.
As a side note, I noced that in the UDAQ's spreadsheet, the emission factors referenced are from AP-42
Fourth Edion which is a version of AP-42 from the mid 1980's. The current version of AP-42, which is the
Fih Edion, came out in the mid 1990's and is the most recent version of AP-42. Trinity typically uses the
latest emission factors and emission guidance that are available when esmang facility emissions.
If you have further quesons, don't hesitate to contact me.

Hi Linda,
Thanks for sending this over. I agree with what you are saying about the more conservative emission rates-- this update
shouldn't cause any modeling issues.

The DAQ has elected to use the AP-42 4th edition emission factors for storage piles to simplify the calculation process for
sources. The 5th edition splits storage pile emissions into drop operation emissions and wind erosion emissions. The drop
operation emissions are calculated using particle size, wind speed, and material moisture content. The wind erosion
emissions are calculated using total exposed surface area (requires storage pile height), wind speed, friction velocity for
erodible material. If you would like to calculate storage pile emissions using 5th edition guidance you are welcome to.
Please see AP-42 sections 13.2.4 and 13.2.5 for reference.
I am going to proceed using the attached calculations. However, if you plan to use the 5th edition of AP-42 and
recalculate, please let me know.
Thanks,
Dungan

Hi Shane,
I wanted to ask you about the current disturbed ground recordkeeping/reporting conditions in your existing permit.
Approval Order DAQE-AN132830006-20 states that disturbed areas shall not exceed 100 acres and that the owner
operator shall not exceed 500 'disturbance-acres' per 12-month. A 'disturbance-acre' is determined by multiplying the
disturbed area by the number of disturbances each day. This is outdated language and requires you to keep daily records
of 'disturbance-acres'.
Current language would limit the total acreage of disturbed ground, but wouldn't require keeping daily records of
disturbances or disturbance-acres. Since I am adjusting the storage pile limit, I wanted to see if you had an interest in
updating the disturbed ground limits to better reflect your facilities current conditions. I've attached a screenshot of the
language for your reference. Let me know what you think.
Thanks,
Dungan

Shane,
If you want to increase the disturbed ground acreage instead of just trying to update the permitting language, you will
need to work with your consultants and update the NOI for this project. Increasing the storage pile size will increase PM10
& PM2.5 emissions and I think the modeling analysis will need to be updated. Let me know if you intend to proceed in this
way.
Thanks,

Hi Shane,
After reviewing the emissions generated for 100 acres of disturbed area and speaking with my manager, I won't be able to
remove the disturbance acres recordkeeping from the permit without further permit modification. Using our current
emission calculation methodology, 100 acres of storage piles would produce ~19 tons per year (TPY) of PM10 and ~3
TPY of PM2.5. This is a fair bit more than what the Plymouth Pit is currently permitted to emit site-wide. We don't
calculate emissions using disturbance-acres anymore, but I am guessing that this limited PM emissions from disturbed
ground back when the permit was originally issued. Since removing the disturbance-acres recordkeeping would lead to a
net increase in PM, you would have to redo emission estimates (and modeling) to account for the 100 acres of disturbed
ground calculated with current methodology.
I am going to recommend that you don't attempt to remove the disturbance-acres language and recordkeeping from the
permit because several more tons of PM10 and PM2.5 would be added to the site totals and I think you could have
trouble meeting the NAAQS with modeling analysis. I apologize for any confusion this has caused.
The DAQ modeling group has completed their modeling analysis and agrees that winter time operation can be extended
to 6:00AM to 12:00AM as requested. I will move forward with this project unless you have any other questions or
requests.
Thanks,
Dungan

2.0 SOURCE DESCRIPTION
The following sections describe the operations and emission sources at the Whitaker Plymouth Pit.
2.1 Aggregate Operations

According to DAQE-AN132830006-20, Whitaker Construction Company operates an aggregate processing
facility called the Plymouth Pit located at 20965 Old Hwy. 13 in Box Elder County. The equipment on site
includes crushers, screens, conveyors, feeders, and mobile equipment such as loaders, haul trucks, and water
trucks. Line power is used to operate the equipment on site. Whitaker Construction Company produces
aggregate materials not to exceed 550,000 tons per rolling 12-month period.
2.2 Storage Piles and Mining Area

Storage piles associated with aggregate operations currently occupy 3 acres. In this NOI, Whitaker is
requesting to increase the size of the storage pile area to 9 acres. Water is applied to the piles to control
fugitive particulate matter (PM) emissions.
2.3 Unpaved and Paved Haul Roads

The haul roads at Plymouth Pit are unpaved and do not exceed 0.25 miles in length. The paved haul road
section is 0.12 miles. The total haul road length, including paved and unpaved haul roads does not exceed
0.37 miles. The paved haul roads are vacuumed swept and flushed with water, as needed, to maintain the
opacity limit listed in DAQE-AN132830006-20. The loader operational areas do not exceed 0.05 miles in length.

2.4 Schedule

Aggregate operations are currently performed from 6:00 AM to 6:00 PM from November 1 through March 31.
Operations from April 1 through October 31 are not restricted. For this NOI, the modified operating hours
proposed to be 06:00 to 24:00 for November 1 through March 31.

Whitaker Construction Company / Notice of Intent Plymouth, Utah Trinity Consultants 3-1
3.0 AIR EMISSIONS
Operations at the Whitaker Plymouth Pit generate criteria pollutant emissions in the form of PM10 and PM2.5
(particulate matter with aerodynamic diameters less than or equal to 10 micrometers and 2.5 micrometers
respectively). Current Potential to Emit (PTE) emission estimates, obtained from DAQE-AN132830006-20, are
presented in Table 3-1. The proposed increase in PM emissions from the requested change in storage pile
area size as well as the post change projected facility-wide PTE emissions are also presented in Table 3-1.
PTE emission calculations are presented in Appendix A. These emission estimates are based on EPA guidance
as published in Compilation of Air Pollution Emission Factors, Volume I: Stationary Point and Area Sources or
AP-42, fuel type, material throughput, and operating hours.

3.1 Aggregate Operations

Fugitive emissions for aggregate operations are generally controlled by residual moisture content or by water
sprays as necessary for feeders, conveyor drop points, screens, and crushers. Haul vehicle traffic on unpaved
roads and front-end loader operation areas are controlled by wet suppression. Dozing, feeding, stockpiling,
and load-out of materials generally rely on residual moisture content for fugitive emission control and watering
of stockpiles to control particulate emissions.

Hourly PM10 and PM2.5 emissions for feeders, conveyors, drop points, screens, and crushers were derived from
AP-42, Section 11.19, Crushed Stone Processing and Pulverized Mineral Processing, August 2004, Table
11.19.2-2 and an annual throughput of 550,000 TPY. Crushing emissions were based on the throughput of
550,000 TPY and 250 TPH for two crushers. PM10/PM2.5 emissions from the aggregate operations will be
controlled through wet suppression.

PM10/PM2.5 emissions from storage piles were based on AP-42, Section 11.9, Western Surface Coal Mining,
Table 11.9-4 and 9 acres. Per the Utah Division of Air Quality (UDAQ), a 50% control factor was applied
through wet suppression. Exposed area emissions were also based on AP-42, Section 11.9, Western Surface
Coal Mining, and 10 acres. A PM2.5/PM10 ratio of 0.15, based on the Midwest Research Institute’s Background
Document for Revisions to Fine Fraction Ratios Used for AP-42 Fugitive Emission Factors, prepared for the
WRAP, was applied to determine PM2.5 emissions. Fugitive emissions from conveyor operations are based on
Table 11.19.2-2 and a throughput of 550,000 TPY. Fugitive emissions from dozer operations are based AP-
42, Section 11.9, Western Surface Coal Mining.

Whitaker Construction Company / Notice of Intent Plymouth, Utah Trinity Consultants 3-2
3.2 Unpaved Roads

PM10 and PM2.5 unpaved road emissions from aggregate production were based AP-42, Section 13.2.2,
Unpaved Roads and an 85% control efficiency through frequent watering and chemical suppressants per
UDAQ’s January 12, 2015 memo, Emission Factors for Paved and Unpaved Haul Roads. Emissions were
projected based on the plant road layouts, vehicle weights, hauling capacity, and increased aggregate plant
throughput.
3.3 Paved Roads

PM10 and PM2.5 paved road emissions were based AP-42, Section 13.2.2, Unpaved Roads and a 90% control
efficiency through frequent vacuum sweeping and watering of pavement as per UDAQ’s January 12, 2015
memo, Emission Factors for Paved and Unpaved Haul Roads. Emissions were projected based on the plant
road layouts, vehicle weights, and hauling capacity.

Whitaker Construction Company / Notice of Intent Plymouth, Utah Trinity Consultants 4-3
4.0 BEST AVAILABLE CONTROL TECHNOLOGY
Per Utah Air Rules R307-400, best available control technology (BACT) is defined as an emissions limitation
(including a visible emissions standard) based on the maximum degree of reduction for each air contaminant
which would be emitted from any proposed stationary source or modification which the director, on a case-
by-case basis, taking into account energy, environmental, and economic impacts and other costs, determines
is achievable for such source or modification through application of production processes or available methods,
systems, and techniques, including fuel cleaning or treatment or innovative fuel combustion techniques for
control of such pollutant. BACT analyses for the emissions from the proposed equipment at the Plymouth Pit
are discussed in the following sections.

4.1 BACT for Storage Piles

Fugitive particulate (PM10/PM2.5) emissions will be emitted from the outdoor storage piles from material loading
and unloading as well as wind.
4.7.1 BACT for PM10/PM2.5
Three control options were identified for controlling PM10 and PM2.5 emissions from storage piles. They are:

► water sprays
► full enclosure
► partial enclosure

Full enclosure of piles, the most effective control option, is typically used at coal processing plants where the
coal needs to be kept dry. These enclosures are usually for piles smaller than what is typically at aggregate
operations. The Plymouth site will have up to 9 acres of storage piles throughout the property. It is practically
not feasible at aggregate, sand, or gravel operations to enclose the piles due to cost and the dynamic nature
and the location change of mining operations.

Partial enclosures are easier to implement but are still costly and to maintain a required opacity limit, water
sprays are still needed. In very windy areas, barriers can be installed to reduce the impact of wind on storage
piles.

Water systems are designed to spray storage piles. These systems are relatively inexpensive and can be
modified to maintain the UDAQ required opacity limit. The DAQ assumes a 50% control efficiency of fugitive
emissions when water sprays are utilized to maintain an opacity limit. This control technology is commonly
implemented on storage piles.

Thus, Whitaker will maintain water systems to reduce PM10 and PM2.5 emissions from aggregate, gravel, or
sand storage piles. The use of these water spray systems is considered BACT.

5.1 R307-101 General Requirements

Chapter 19‐2 and the rules adopted by the Air Quality Board constitute the basis for control of air pollution
sources in the state. These rules apply and will be enforced throughout the state and are recommended for
adoption in local jurisdictions where environmental specialists are available to cooperate in implementing rule
requirements.

National Ambient Air Quality Standards (NAAQS), National Standards of Performance for New Stationary
Sources (NSPS), National Prevention of Significant Deterioration of Air Quality (PSD) standards, and the
National Emission Standards for Hazardous Air Pollutants (NESHAPS) apply throughout the nation and are
legally enforceable in Utah.

5.2 R307-102 General Requirements: Broadly Applicable Requirements

Emission of air contaminants in sufficient quantities to cause air pollution as defined in R307-101-2 is
prohibited. The State statute provides for penalties up to $50,000/day for violation of State statutes,
regulations, rules or standards. In addition, the owner or operator of any stationary air pollutant source in
Utah shall furnish to the director the periodic reports required under Section 19-2-104(1)(c) and any other
information as the director may deem necessary to determine whether the source is in compliance with Utah
and Federal regulations and standards. The information thus obtained will be correlated with applicable
emission standards or limitations and will be available to the public during normal business hours at the

5.3 R307-107 General Requirements: Breakdowns

The breakdown provisions of R307-107 will apply to the Plymouth Pit operations. The owner or operator of a
source shall report breakdowns to the director within 24 hours of the incident via telephone, electronic mail,
fax, or other similar method. A detailed written description of the circumstance including a corrective program
directed at preventing future such incidents, shall be submitted within 14 days of the onset of the incident.

The breakdown incident report shall include the cause and nature of the event, estimated quantity of emissions
(total and excess), time of emissions and any relevant evidence, including, but not limited to, evidence that:

a) There was an equipment malfunction beyond the reasonable control of the owner or operator,
b) The excess emissions could not have been avoided by better operation, maintenance or improved
design of the malfunctioning component,
c) To the maximum extent practicable, the source maintained and operated the air pollution control
equipment and process equipment in a manner consistent with good practice for minimizing emissions,
including minimizing any bypass emissions,
d) Any necessary repairs were made as quickly as practicable, using off-shift labor and overtime as
needed and as possible,
e) All practicable steps were taken to minimize the potential impact of the excess emissions on ambient
air quality, and
f) The excess emissions are not part of a recurring pattern that may have been caused by inadequate
operation or maintenance, or inadequate design of the malfunctioning component.

The burden of proof is on the owner or operator of the source to provide sufficient information to demonstrate
the elements listed above.

5.4 R307-110 General Requirements: State Implementation Plan

To meet the requirements of the Federal Clean Air Act, the Utah State Implementation Plan (SIP) must be
incorporated by reference into the rules. Copies of the SIP are available on the division’s website.

5.5 R307-130 General Penalty Policy

This policy provides guidance to the director of the Air Quality Board in negotiating with air pollution sources
penalties for consent agreements to resolve non-compliance situations. It is designed to be used to determine
a reasonable and appropriate penalty for the violations based on the nature and extent of the violations,
consideration of the economic benefit to the sources of non-compliance, and adjustments for specific
circumstances.

Whitaker Construction Company / Notice of Intent Plymouth, Utah Trinity Consultants 5-6
Violations are grouped in four general categories based on the potential for harm and the nature and extent
of the violations. Penalty ranges for each category are as follows.

(1) Category A. $7,000 - $10,000 per day;
(2) Category B. $2,000 - $7,000 per day;
(3) Category C. Up to $2,000 per day; and
(4) Category D. Up to $299.

The amount of the penalty within each category may be adjusted and/or suspended in part based upon the
following factors:

1) Good faith efforts to comply or lack of good faith. Good faith considers the openness in dealing with the
violations, promptness in correction of problems, and the degree of cooperation with the State to include
accessibility to information and the amount of State effort necessary to bring the source into compliance.
2) Degree of willfulness and/or negligence. In assessing willfulness and/or negligence, factors to be
considered include how much control the violator had over and the foreseeability of the events constituting
the violation, whether the violator made or could have made reasonable efforts to prevent the violation,
and whether the violator knew of the legal requirements which were violated.
3) History of compliance or non-compliance. History of non-compliance includes consideration of previous
violations and the resource costs to the State of past and current enforcement actions.
4) Economic benefit of non-compliance. The amount of economic benefit to the source of non-compliance
would be added to any penalty amount determined under this policy.
5) Inability to pay. An adjustment downward may be made, or a delayed payment schedule may be used
based on a documented inability of the source to pay.

5.6 R307-150 Emission Inventories

The purpose of Rule R307-150 is:

a. to establish by rule the time frame, pollutants, and information that sources must include in inventory
submittals; and
b. to establish consistent reporting requirements for stationary sources in Utah to determine whether sulfur
dioxide emissions remain below the sulfur dioxide milestones established in the State Implementation Plan
for Regional Haze, section XX.E.1.a, incorporated by reference in Section R307-110-28.

The requirements of Rule R307-150 replace any annual inventory reporting requirements in approval orders
or operating permits issued prior to December 4, 2003. Emission inventories shall be submitted on or before
April 15 of each year following the calendar year for which an inventory is required. The inventory shall be
submitted in a format specified by the Division of Air Quality following consultation with each source. The
executive secretary may require at any time a full or partial year inventory upon reasonable notice to affected
sources when it is determined that the inventory is necessary to develop a state implementation plan, to
assess whether there is a threat to public health or safety or the environment, or to determine whether the
source is in compliance with Title R307.

Whitaker Construction Company / Notice of Intent Plymouth, Utah Trinity Consultants 5-7
Each owner or operator of a stationary source subject to this rule shall maintain a copy of the emission
inventory submitted to the Division of Air Quality and records indicating how the information submitted in the
inventory was determined, including any calculations, data, measurements, and estimates used. The records
under Section R307-150-4 shall be kept for ten years. Other records shall be kept for a period of at least five
years from the due date of each inventory. The owner or operator of the stationary source shall make these
records available for inspection by any representative of the Division of Air Quality during normal business
hours.

5.7 R307-201 Emission Standards: General Emission Standards

R307-210 establishes emission standards for all areas of the state except for sources listed in Section IX, Part
H of the state implementation plan or located in a PM10 nonattainment or maintenance area.

1) Visible emissions from installations constructed on or before April 25, 1971, except diesel engines,
shall be of a shade or density no darker than 40% opacity, except as otherwise provided in these
rules.
2) Visible emissions from installations constructed after April 25, 1971, except diesel engines shall be of
a shade or density no darker than 20% opacity, except as otherwise provided in these rules.
3) Visible emissions for all incinerators, no matter when constructed, shall be of shade or density no
darker than 20% opacity.
4) No owner or operator of a gasoline powered engine or vehicle shall allow, cause or permit visible
emissions.
5) Emissions from diesel engines, except locomotives, manufactured after January 1, 1973, shall be of a
shade or density no darker than 20% opacity, except for starting motion no farther than 100 yards or
for stationary operation not exceeding three minutes in any hour.
6) Emissions from diesel engines manufactured before January 1, 1973, shall be of a shade or density
no darker than 40% opacity, except for starting motion no farther than 100 yards or for stationary
operation not exceeding three minutes in any hour.
7) Visible emissions exceeding the opacity standards for short time periods as the result of initial warm-
up, soot blowing, cleaning of grates, building of boiler fires, cooling, etc., caused by start-up or
shutdown of a facility, installation or operation, or unavoidable combustion irregularities which do not
exceed three minutes in length (unavoidable combustion irregularities which exceed three minutes in
length must be handled in accordance with R307-107), shall not be deemed in violation provided that
the director finds that adequate control technology has been applied. The owner or operator shall
minimize visible and non-visible emissions during startup or shutdown of a facility, installation, or
operation through the use of adequate control technology and proper procedures.
8) Compliance Method. Emissions shall be brought into compliance with these requirements by reduction
of the total weight of pollutants discharged per unit of time rather than by dilution of emissions with
clean air.
9) Opacity Observation. Opacity observations of emissions from stationary sources shall be conducted in
accordance with EPA Method 9. Opacity observers of mobile sources and intermittent sources shall
use procedures similar to Method 9, but the requirement for observations to be made at 15 second
intervals over a 6-minute period shall not apply.

establishment pursuant to the requirements of R307-401-8, or issue an order prohibiting the proposed
construction, installation, modification, relocation or establishment if it is deemed that any part of the proposal
is inadequate to meet the applicable requirements of R307.

5.13 R307-410 Permits Emissions Impact Analysis

This rule establishes the procedures and requirements for evaluating the emissions impact of new or modified
sources that require an approval order under R307-401 to ensure that the source will not interfere with the
attainment or maintenance of any NAAQS. The rule also establishes the procedures and requirements for
evaluating the emissions impact of hazardous air pollutants. The rule also establishes the procedures for
establishing an emission rate based on the good engineering practice stack height as required by 40 CFR
51.118.

All estimates of ambient concentrations derived in meeting the requirements of R307 shall be based on
appropriate air quality models, data bases, and other requirements specified in 40 CFR Part 51, Appendix W,
Guideline on Air Quality Models, which is hereby incorporated by reference. Where an air quality model
specified in the Guideline on Air Quality Models or other EPA approved guidance documents is inappropriate,
the director may authorize the modification of the model or substitution of another model. In meeting the
requirements of federal law, any modification or substitution will be made only with the written approval of
the Administrator, EPA.

Prior to receiving an approval order under R307-401, a new source in an attainment area with a total controlled
emission rate per pollutant greater than or equal to amounts specified in Table 1, or a modification to an
existing source located in an attainment area which increases the total controlled emission rate per pollutant
of the source in an amount greater than or equal to those specified in Table 1, shall conduct air quality
modeling, as identified in R307-410-3, to estimate the impact of the new or modified source on air quality
unless previously performed air quality modeling for the source indicates that the addition of the proposed
emissions increase would not violate a National Ambient Air Quality Standard, as determined by the Director.

• sulfur dioxide - 40 tons per year
• oxides of nitrogen - 40 tons per year
• PM10 - fugitive emissions 5 tons per year and fugitive dust
• PM10 - non-fugitive emissions 15 tons per year or non-fugitive dust
• carbon monoxide - 100 tons per year
• lead - 0.6 tons per year

The ambient air impact from emissions of hazardous air pollutants is also to be reviewed based on the
guidance in R307-410-5.

6.0 DISPERSION MODELING
In support of Whitaker’s Plymouth Pit, this air quality modeling analysis was conducted in accordance with
Utah Title R307-410. The following sections describe the methods used and results of the dispersion modeling
to demonstrate compliance with applicable State of Utah Regulation.

6.1 Dispersion Modeling Applicability

Per Utah Title R307-410, a new or modified source located in an attainment area which increases the total
controlled emission rate per pollutant of the source above the modeling threshold, as listed in Table 6-1, is
required to conduct an air quality modeling analysis. As shown in Table 6-1, by rule, dispersion modeling is
not required for this permit application. However, aggregate and operations are currently being conducted at
the site under Approval Order DAQE-AN13830006-20. As part of the previous Approval Order, UDAQ
conducted an air quality impact analysis using EPA’s AERMOD system and established that the facility is
capable of operating from 6:00 AM to 6:00 PM for November 1 through March 31 with operational hours from
April 1 through October 31 not being restricted.

Whitaker is seeking to modify the plant operations schedule to increase the operational hours from November
1 through March 31 to 06:00 AM to 12:00 AM. Dispersion modeling was performed with the proposed changes
to demonstrate compliance with the National Ambient Air Quality Standards (NAAQS). This section outlines
the changes to the operation schedule being requested and presents the results of the air quality analysis
Table 6-1 Dispersion Modeling Thresholds and Controlled Emission Increases
Pollutant Modeling Threshold (tons/year)
Controlled Emissions Increase (tons/year)
Modeling Required (Y/N)
PM10 15/5a 3.45 N
PM2.5 10 0.26 N
a15 tons per year for non-fugitive emissions, 5 tons per year for fugitive emissions.

Utah Administrative Code (UAC) R307-410-5 presents emission threshold values (ETVs) as a HAP-specific
threshold to determine if dispersion modeling will be required. The ETV is the product of the threshold limit
values (TLVs) listed in the American Conference of Governmental Industrial Hygienists (ACGIH) “Threshold
Limit Values for Chemical Substances and Physical Agents” handbook and an emission threshold factor
(defined in Table 2 of R307-410-5) which is based on the type of release point (vertically restricted or vertically
unrestricted) and the distance to ambient air. Net emissions found to be greater than the ETV are required to
conduct a dispersion modeling analysis to be compared to applicable toxic screening levels (TSLs). No HAPS
modeling was required for the Plymouth Pit.

6.2 Near-Field Dispersion Modeling Setup

Near-field dispersion modeling was conducted using the latest version of the AERMOD modeling system
(Version 23132). With the exception of the change in operating schedule, the increased storage pile acreage,
and background concentrations included in the model, all model input data (meteorological data, source
parameters, and receptor grid) were retained in the model setup provided by UDAQ. Source parameters are
provided in Appendix B.

Whitaker Construction Company / Notice of Intent Plymouth, Utah Trinity Consultants 6-2

Meteorological data used in the analysis were provided by UDAQ and consisted of surface data collected by
Nucor in Plymouth and upper air data collected by the National Weather Service in Salt Lake City for 2008.
Surface measurements were collected by Nucor using a 50-meter-tall tower operated under US EPA quality
assurance and quality control procedures. Consistent with 40 CFR Part 51 Appendix W, Guideline on Air Quality
Models, turbulence data for the meteorological tower were used in lieu of the surface friction velocity
correction algorithm (ADJ_U*).

Background concentrations for PM10 were obtained from the Harrisville monitor located in Weber County,
Utah. To represent seasonal variability, monthly PM10 background concentrations were determined using
monitoring data collected by UDAQ from 2021 through 2023.

The maximum concentration from each year was removed from the background concentration to meet the
form of the PM10 standard. The monthly values are added to the model input file and AERMOD adds the
corresponding background concentration to the model-predicted concentration. Table 6-2 presents the
monthly maximum concentrations by year and the monthly background concentration added to the model
input file.

6.3 Near-Field Dispersion Modeling Results for PM10
Near-field dispersion modeling was conducted for the criteria pollutant PM10 using AERMOD input data
provided by UDAQ and the proposed operating schedule. Model-predicted concentration results and a
comparison to the NAAQS is provided in Table 6-3. Background concentrations, which include pollutant
concentrations due to natural sources, nearby sources other than the one(s) currently under consideration,
and unidentified sources, were added to model-predicted concentrations by the model. The NAAQS modeling
summary results are found in Appendix C. Figure 6-1 presents an isopleth plot for the NAAQS analysis.

In accordance with UAC R307-410-4, modeling previously performed by UDAQ was refined to demonstrate
that the increase in stockpile size and the proposed operations schedule would not violate the NAAQS. The
updated modeling demonstrated that these changes remain protective of the 24-hour PM10 NAAQS.

Dungan,

We had some help drafting this NOI modification for our Plymouth Pit. May I send this through you or is there a preferred
location to submit the request?

Thanks,

Hi Shane,
Thanks for sending this NOI over, I have forwarded this project to my manager. I'm guessing the project will be assigned
to me, but if it is assigned to a different engineer they will be in contact with you shortly.
Thanks,
Dungan

Hi Alan,

up the project in TEMPO when you get the chance?
Thanks,
