435-770-4319, [e-mail]

OPERATING STATUS: Operating normally.

PROCESS DESCRIPTION: Recycled asphalt plant. Raw aggregate material is trucked to the
site, bottom-dropped to a feeder, and conveyed to the piles
according to size. Aggregate is dumped into a feed bin by front
end loader. The aggregate is screened and mixed with lime and
fed into the dryer (first drum). The first drum dries and mixes the
lime and aggregate. The outside drum is used to add recycle
material to the virgin asphalt and to mix the final asphalt
product. The asphalt is conveyed to storage silos for gravity drop
to delivery trucks. The company typically uses some recycled
aggregate material. Crushed recycled asphalt is brought into the
yard by truck and is dumped to a pile. An impact crusher, cone
crusher, and screen are located on site to crush and size the raw
recycle material. The sized recycled material is dumped into a
bin and metered into the second drum for mixing with virgin
product. Emissions from the asphalt plant are controlled by a
baghouse. There are water sprays on the pug mill that slurries
lime prior to mixing with damp aggregate. An on-site water
truck is used for dust control.

INTRODUCTION

Test Purpose

This test was conducted to determine compliance with the particulate matter (PM) emission
limits of the facility’s Approval Order (AO), Number DAQE-AN122720011-20, dated
December 16, 2020. Emissions are expressed in terms of grains per dry standard cubic foot
(gr/dscf) and pounds per hour (lb/hr) where applicable.

Test Location and Type of Process

The Astec 400 tph drum asphalt plant was located at 1550 West 1900 West, West Haven, Utah.
Sand, gravel, recycled, asphalt and oil are mixed and dried in a natural gas fired drum. The
exhaust gas passes through a baghouse. A facility schematic is shown as Figure 1 found in
Appendix D.

Test Dates

Two test runs were completed August 30, 2021, and the last test run was completed August 31,
2021.

Pollutants Tested and Methods Applied

These tests were a gravimetric determination of PM particulate in accordance with EPA Methods
5 and 202. The reasons for using Method 5 rather than Method 201A are twofold: 1) even
though the stack gas is not saturated with water droplets, the relatively high moisture content of
the stack exhaust leads to a low Method 201A sample rate, and 2) previous testing at the facility
have shown that the Method 5 results were well under the PM emission limits.

Condensable particulate matter (PM) was sampled as the back-half of the method 5 sample train.

Test Participants

Deviations From EPA Methods

None.

Quality Assurance

Testing procedures and sample recovery techniques were according to those outlined in the
Federal Register and the Quality Assurance Handbook for Air Pollution Measurement Systems.

Condensable particulate matter results are found on table IV in Appendix A.

Process Data

The process was operated according to standard procedures. All pertinent process data was
available for recording by agency personnel. Aggregate, recycled asphalt, asphalt tar feed rate,
and the baghouse differential pressure drop were recorded on production sheets found in
Appendix D.

Allowable Emissions

The allowable of PM emissions for this source are 0.030 gr/dscf and 5.55 lb/hr while running
virgin or RAP material.

The allowable of PM10 and PM 2.5 emissions for this source are 0.024 gr/dscf and 5.55 lb/hr while
running virgin or RAP material.

Description of Collected Samples

The front washes were clear in appearance. There was a small amount of visible tan colored
particulate on the test filters.

SAMPLING AND ANALYTICAL PROCEDURES

Sampling Port Location

Port location is depicted in Figure 1. The inside dimensions of the rectangular stack were 33.0
by 49.0 inches. Six, three-inch diameter ports were available for testing. These ports were
located 5.71 equivalent diameters (225 inches) downstream from the last disturbance and 3.70
equivalent diameters (146 inches) upstream from the next disturbance.

Sampling Point Location

Table III shows the distance of each sampling point from the inside wall according to EPA
Method 1. Each point was marked with a wrapping of glass tape. These points were determined
by measuring the distance from the inside wall and adding the reference (port) measurement.
TABLE III Sampling Point Location
Sample Point Distance (inches) from Inside Wall
1 7.63
2 15.88
3 24.13
4 32.38

Sampling Train Description

To determine the actual emission rates for this stack, 40 CFR 60, Appendix A, Method 5, and 40
CFR 51, Appendix M, Method 202 were followed.

All sampling trains were made of Teflon, stainless steel and glass to prevent interference of the
sampled gas. The stack analyzer used to conduct Methods 5 and 202 was constructed to meet the
specifications outlined in the CFR. The temperature sensors were K-type thermocouples.
Heater, vacuum and pitot line connections were designed to be interchangeable with all units
used by the tester. Stainless steel probe liners were used for each test run. Figure 2 in Appendix
E is a sketch of the Method 5/202 sampling train. Sample boxes were prepared for testing by
following the prescribed procedure outlined in Methods 5 and 202.

7
Sampling and Analytical Procedures

All sampling and analytical test procedures employed were as specified in 40 CFR 60 Appendix
A, Method 5 and 40 CFR 51, Appendix M, Method and 202.

Quality Assurance

All equipment set-up, sampling procedures, sample recovery and equipment calibrations were
carried out according to the procedures specified in 40 CFR 60 Appendix A, Method 5and 40
CFR 51, Appendix M, Method 202 and the Quality Assurance Handbook for Air Pollution
Measurement Systems.

COMPLIANCE EMISSION TESTING PROTOCOL
GRANITE CONSTRUCTION COMPANY
ASTEC 400 DRUM ASPHALT PLANT BAGHOUSE EXHAUST
WEST HAVEN FACILITY

Project Organization and Responsibility

The following personnel and the testing contractor are presently anticipated to be involved in the
testing program. The Utah Department of Environmental Quality (UDEQ) may have their own
personnel to observe all phases including the process.

Company Contacts
Granite Construction Company Mark Greenwood [phone]
1000 North Warm Springs Road
Salt Lake City, UT 84116

Test Contractor:
TETCO Dean Kitchen [phone]
391 East 620 South
American Fork, UT 84003

Facility Location

The facility is located at 1550 South 1900 West, West Haven, Utah. The source to be tested is the
Astec 400 tph drum asphalt plant baghouse exhaust.

Test Purpose and Methods Applied

This test will be conducted to determine compliance with the PM emission limit for the asphalt
plant baghouse exhaust as established in the facility=s Utah Department of Environmental Quality,
Division of Air Quality Approval Order DAQE-AN122720011-20, dated December 16, 2020.

Testing procedures will include accumulating process and production data as well as testing for
PM particulate matter emissions using EPA Methods 5 and 202. Condensable particulate matter
(CPM) will not be used for compliance demonstration but shall be used for inventory purposes.

Test Date and Time

It is planned to complete all testing August 16-17, 2021. It is anticipated that the test crew will
arrive, set up the test equipment, and begin testing on the 16th and continue August 17th as needed.

Operational Data and Instrumentation

Copies of all operational and instrumentation data will be made available to agency personnel.
Production will be monitored and recorded by Granite Construction personnel. Asphalt
production, pressure drop, and percent recycle will be recorded during the test.

Access to Sample Site

The sample site is accessed by man-lift.

Potential Hazards

Estimates of Test Parameters

Stack flow TBD
Moisture TBD
Stack Temperature TBD

Test Procedures

PM Measurements

The following are the procedures that TETCO will follow for the Method 5/202 compliance tests:

1. The dimensions of the rectangular stack are 33.0 by 49.0 inches. Six sample ports are
located 225 inches (5.71 diameters) downstream and 146 inches (3.70 diameters) upstream
from any flow disturbance. It is planned to sample 5 sample points per port, or a total of
thirty sample points.

2. EPA Method 2 will be used to determine the gas stream velocity. The type "S" pitot tubes

3
will be used with a Cp factor of 0.84. Dual inclined/vertical manometers with graduations
in .01 of an inch of water will be used. If the measured pressure differential is below 0.05
inches of water a more sensitive manometer will be used with graduation marks of 0.005
inches of water. Direction of gas flow will be checked for gas cyclonics prior to testing.

3. EPA Method 3 will be used to determine the gas stream dry molecular weight. A sample
will be collected in a gas bag and will be analyzed by Orsat at the test=s conclusion. The
gas sample will be taken immediately following the console critical orifice.

4. EPA Method 4 will be used to determine the gas stream moisture content.

5. EPA Method 5 will be used to measure the particulate matter emission rate. The
minimum run duration will be 60 minutes, and the minimum sample volume will be 31.8
dry standard cubic feet.

6. The glass fiber filters that will be used meet the specifications required of the method.

7. The probe liners will be stainless steel.

8. EPA Method 202 will be used to measure condensable emissions in the back-half
catch.

9. The barometric pressure will be measured with a barometer which is periodically checked
against a mercury barometer. The barometer will be checked prior to testing to assure an
accurate barometric pressure.

10. Current calibration data is submitted with this protocol. Nozzle calibration which will be
done at the test site. Nozzle calibration will be included on the first page of each set of run
sheets for each respective test run. Any calibration that is not current will be re-calibrated
prior to the test dates.

11. Any necessary preparation and clean-up by the contractor will be performed in the
contractor's sampling trailer or a clean area on Granite Construction Company=s property.
The laboratory work and analysis will be done by the contractor as soon as possible after
the test project at 391East 620 South, American Fork, Utah.

Quality Assurance

All testing and analysis in these tests will be conducted according to Methods 5 and 202 and
appropriate sections of the EPA Quality Assurance Handbook for Air Pollution Measurement
Systems Volume III.

Reporting

Reporting will be prepared by the testing contractor according to EPA Quality Assurance
Guidelines. Complete copies of raw data, calculations and summary of test will be included in the
test report. All process and production data will be recorded and retained for inspection and
copying by UDEQ. The reports will be submitted to UDEQ within 30 days following completion
of the test.

(MP model has polycarbonate cover).Accuracy: 2% of full scale (±3% on -0, -100PA, -125PA, -10MM and ±4% on -00, -60PA, -6MM), throughout range at70°F (21.1°C); High accuracy version: ±1% on full scale(±1.5% on -0, -100PA, -125PA, -10MM and ±2% on -00, -60PA, -6MM).Pressure Limits: -20˝ Hg to 15 psig.† (-0.677 bar to 1.034bar); MP option: 35 psig (2.41 bar), HP option: 80 psig (5.52bar).Enclosure Rating:IP67.Overpressure: Relief plug opens at approximately 25 psig(1.72 bar), standard gages only. The blowout plug is not usedon models above 180 inches of water pressure, medium orhigh pressure models, or on gages which require an elastomerother than silicone for the diaphragm.Temperature Limits: 20 to 140°F (-6.67 to 60°C). *Lowtemperature models available as special option.Size: 4˝ (101.6 mm) diameter dial face.Mounting Orientation: Diaphragm in vertical position.Consult factory for other position orientations.Process Connections: 1/8˝ female NPT duplicate high andlow pressure taps - one pair side and one pair back.Weight: 1 lb 2 oz (510 g), MP & HP 2 lb 2 oz (963 g).Agency Approvals:RoHS.†For applications with high cycle rate within gage total pressure rating,next higher rating is recommended. See Medium and High pressureoptions.Note:May be used with hydrogen when ordering Buna-N diaphragm.Pressure must be less than 35 psi.
STANDARD GAGE ACCESSORIES: Two 1/8˝ NPT plugs forduplicate pressure taps, two 1/8˝ pipe thread to rubber tubingadapters and three flush mounting adapters with screws.
MP AND HP GAGE ACCESSORIES:Mounting ring and snapring retainer substituted for 3 adaptors, 1/4” compression fittingsreplace 1/8” pipe thread to rubber tubing adaptors.
OVERPRESSURE PROTECTION:Standard Magnehelic®Differential Pressure Gages are rated for a maximumpressure of 15 psig and should not be used where that limitcould be exceeded. Models employ a rubber plug on the rearwhich functions as a relief valve by unseating and venting thegage interior when over pressure reaches approximately 25psig (excludes MP and HP models). To provide a free path forpressure relief, there are four spacer pads which maintain .023˝clearance when gage is surface mounted. Do not obstruct thegap created by these pads.
*The blowout plug is not used on models above 180 inches of water pressure, medium or high pressure models, or on gages which require an elastomer other than silicone for the diaphragm.

PIPE MOUNTINGTo mount gage on 1-1/4” - 2” pipe, order optional A-610 pipemounting kit.
TO zERO GAGE AFTER INSTALLATIONSet the indicating pointer exactly on the zero mark, using theexternal zero adjust screw on the cover at the bottom. Note thatthe zero check or adjustment can only be made with the highand low pressure taps both open to atmosphere.
OPERATIONPositive Pressure: Connect tubing from source of pressure toeither of the two high pressure ports. Plug the port not used.Vent one or both low pressure ports to atmosphere.Negative Pressure:Connect tubing from source of vacuum ornegative pressure to either of the two low pressure ports. Plugthe port not used. Vent one or both high pressure ports toatmosphere. Differential Pressure:Connect tubing from the greater of twopressure sources to either high pressure port and the lower toeither low pressure port. Plug both unused ports.When one side of the gage is vented in dirty, dusty atmosphere,we suggest an A-331 Filter Vent Plug be installed in the openport to keep inside of gage clean.
A.For portable use of temporary installation use 1/8” pipethread to rubber tubing adapter and connect to source ofpressure with flexible rubber or vinyl tubing.B.For permanent installation, 1/4” O.D., or larger, copper oraluminum tubing is recommended.
MAINTENANCENo lubrication or periodic servicing is required. Keep caseexterior and cover clean. Occasionally disconnect pressurelines to vent both sides of gage to atmosphere and re-zero.Optional vent valves should be used in permanent installations.The Series 2000 is not field serviceable and should be returnedif repair is needed (field repair should not be attempted and mayvoid warranty). Be sure to include a brief description of theproblem plus any relevant application notes. Contact customerservice to receive a return goods authorization number beforeshipping.
WARNINGAttempted field repair may void your warranty. Recalibration orrepair by the user is not recommended.
TROUBLE SHOOTING TIPSGage won’t indicate or is sluggish.1. Duplicate pressure port not plugged.2. Diaphragm ruptured due to overpressure.3. Fittings or sensing lines blocked, pinched, or leaking.4. Cover loose or “O”ring damaged, missing.5. Pressure sensor, (static tips, Pitot tube, etc.) improperly located.6. Ambient temperature too low. For operation below 20°F (-7°C), order gage with low temperature, (LT) option.
INSTALLATIONSelect a location free from excessive vibration and where theambient temperature will not exceed 140°F (60°C). Also, avoiddirect sunlight which accelerates discoloration of the clearplastic cover. Sensing lines may be run any necessary distance.Long tubing lengths will not affect accuracy but will increaseresponse time slightly. Do not restrict lines. If pulsatingpressures or vibration cause excessive pointer oscillation,consult the factory for ways to provide additional damping. All standard Magnehelic®Differential Pressure Gages arecalibrated with the diaphragm vertical and should be used inthat position for maximum accuracy. If gages are to be used inother than vertical position, this should be specified on theorder. Many higher range gages will perform within tolerance inother positions with only rezeroing. Low range models of 0.5”w.c. plus 0.25” w.c. and metric equivalents must be used in thevertical position only.
SURFACE MOUNTING

(El tapón de goma no es usado en los modelos sobre 180 pulgadas de presión de agua, modelos de presión media o alta, o en instrumentos que requierenun elastizado en cualquier otro material que no sea silicona para el diafragma.) Accesorios: Tapones 1/8” NPT para las conexionesduplicadas, dos adaptadores de rosca 1/8” NPT a tubo degoma; y tres adaptadores para montaje al ras y tornillos.
Accesorios para Los Modelos MP y HP:El anillo de montajey el retensor del anillo de presión son substituidos por 3adaptadores, accesorios de compresión de 1/4” remplazan alos adaptadores de rosca 1/8” a tubo de goma.
Protección Para Sobrepresión: Los ManómetrosDiferenciales Magnehelic Estándar están clasificados para unapresión máxima de 15 psi y no se deberían de usar donde ellímite puede excederse. Los modelos emplean un tapón degoma en el trasero que funciona como una válvula de aliviodesmontándose y ventilando el interior del instrumento cuandola sobrepresión alcanza aproximadamente 25 psig. (Losmodelos MP y HP son excluidos) Para proveer un camino librepara el alivio de presión, el instrumento viene con rodilleras quemantienen un espacio de .023” cuando el instrumento esmontado en superficie. No bloque el espacio creado por estasrodilleras.

InstalacíonSeleccione un lugar libe de exceso de vibraciones, y donde latemperatura ambiente no supere los 60°C. Evite luz solardirecta, para evitar decoloración de la cubierta plástica. Lasconexiones de proceso pueden tener cualquier longitud sinafectar la exactitud, pero pueden extender el tiempo derespuesta del instrumento. Si hay pulsación de presión ovibración, consulte a fábrica sobre medios de amortiguación. Los MAGNEHELIC han sido calibrados con el diafragmavertical, y deben ser usados en esas condiciones. Para otrasposiciones, se debe especificar en la orden de provisión. Losde rango elevado pueden ser usados en diversas posiciones,pero se debe reajustar el cero. Los modelos de la serie 2000-00 y equivalentes métricos deben ser usados soloverticalmente.
Montaje en Superficie
Perfore tres orificios separados 120° sobre una circunferenciade 105 mm de diám. y sostenga el instrumento con tres tornillos6-32 de long. apropiada.
Montaje alineado
Perfore un circulo de 115 mm de diám. en el panel, y sostengael instrumento mediante los.
Para instalar el bisel de acero inoxidable
Haga una apertura de 4-9/16 pulgadas en el panel. Inserte elmedidor y asegure con los herrajes de montaje provistos.
Montaje Sobre PipaPara montar el instrumento sobre pipas de 32 a 50 mm dediám., ordene el adaptador opcional A-610.
Puesta a Cero Después de InstalarDeje las conexiones de presión abiertas a atmósfera y ajuste acero desde tornillo del panel frontal.
OperacionPresión Positiva:Conecte la tubería desde la fuente depresión a cualquiera de las dos conexiones de alta presión(HIGH), bloqueando la no usada; Las conexiones de baja(LOW) presión pueden dejarse uno o los dos abiertos a laatmósfera.Presión Negativa: Repita el procedimiento anterior, conectadoen este caso las conexiones de baja presión (LOW). Deje lasotras conexiones abiertas.Presión diferencial:Conecte el tubo correspondiente a lapresión más positiva al cualquiera de los conectores de altapresión (HIGH) bloqueando el no usado, y la más baja presióno presión negativa (vacío) al conector de baja presión (LOW).Puede usarse cualquier conector de cada par, dejando siempreuno bloqueado. Si se deja una conexión abierta a la atmósfera,se recomienda el uso de un filtro tipo A-331 en el lugarcorrespondiente para mantener limpio el interior delinstrumento. Para uso portable, o instalación temporaria, usoadapta dores para rosca de tubo de 1/89 a tubo flexible, yconecte a proceso mediante una tubería de goma, oequivalente. Para instalación permanente, se recomienda eluso de tubo de cobre o aluminio de por lo menos 1/4“ de diám.exterior.
No se requiere mantenimiento específico alguno, ni lubricación.Periódicamente, desconecte el instrumento, ventee la presiónacumulada, y reajuste el cero. Para instalaciones permanentes,se debe usar un juego de válvulas de montaje permanentepara el venteo.El instrumento de Serie 2000 no puede ser re parado en elcampo y debería de ser regresado si reparos son necesarios(Reparos en el campo no deben de ser intentados y puedencancelar la garantía.).
