INTRODUCTION
Test Purpose
The purpose of the test was to fulfill the testing requirements of the facility Approval Order, AO
Number DAQE-AN0412002-04, which requires testing the B Wheat Cleaning Baghouse for PM10
particulate once every 5 years. Results are calculated in terms of grains per dry standard cubic
foot (gr/dscf) and pounds per hour (lb/hr).
Test Location and Type of Process
The Grain Craft facility is located at 220 West 30th Street, Ogden, Utah. The source tested is a
Micro Pulsaire MP160-8 baghouse used for the removal of particulate from the airstream
originating from the B Wheat Cleaning House.
A stack schematic representation is given as Figure 1 in Appendix D.
Test Dates
All three test runs were conducted on March 30 2021.
Pollutants Tested
The tests were a gravimetric determination of PM10 particulate in accordance with EPA Method
201A. Condensible particulate matter (CPM) was not tested as per the test protocol.
Test Participants
State None
Facility Tanner Elliot Tim Becker
TETCO Mike McNamara Reed Kitchen Xaun Dang

EPA Methods Applied
EPA Method 201A was used for each of the tests.
For safety reasons and as per the test protocol, the sample probe was not heated.
Principal of EPA Method 201A
A gas sample is extracted at a constant flow rate through an in-stack sizing device, which separates
particulate matter (PM) greater than PM10 from particulate matter less than PM10. Variations
from sampling conditions are maintained within well defined limits. The particulate mass is
determined gravimetrically after removal of uncombined water.
A schematic of the sampling train is given as Figure 2 in Appendix E.
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.

Production and Process Data
The process was operated according to standard procedures. All process data was made
available to state agency personnel. Baghouse pressure drop readings (p) are found on the
individual field run sheets. See production sheets in Appendix D.
Allowable Emissions
The allowable PM10 particulate matter concentration limit for the B Wheat Cleaning Baghouse is
0.016 gr/dscf as per the facility AO.
Discussion of Errors
None.
Description of Collected Samples
The filters and washes contained no noticeable particulate.

Cyclone Cut-Rate and Isokinetics
The Federal Register specifies that tests for PM10 using EPA Method 201A shall not exceed ± 1u
of the 10u cut-rate, the isokinetics must remain within ± 20% of 100%, and no more than 8% (one
out of twelve) of the measured flow rates (∆P's) shall exceed the calculated P minimum or ∆P
maximum. Table II shows the cut-rate and isokinetics for the EPA Method 201A test conducted
on the Baghouse.

SOURCE OPERATION
Sampling Port Location
Port location is depicted in Figure 1. The inside stack diameter was 28 inches. Two, six-inch
diameter ports were located 2.6 diameters downstream (73.5 inches) from the last disturbance and
0.7 diameters upstream (20 inches) from the next disturbance. Port diameters were six inches.
Sampling Point Location
Table III shows the distance of each sampling point from the inside wall. Each point was marked
with a glass tape wrapping and numbered. These points were determined by measuring the
distance from the inside wall and adding the reference (port) measurement.

Sampling Train Description
To determine the actual emission rates for these stacks 40 CFR 60 Appendix A Methods 1-4, and
40 CFR 51 Appendix M Method 201A were followed.
The sampling train was made of inert materials, (i.e., Teflon, stainless steel, glass, etc.) to prevent
sampled gas and particulate interference.
The stack analyzer used to conduct Methods 1-4 and 201A 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. The probe liner was of 316 stainless steel. A sampling train sketch is found as
Figure 2 in Appendix E.
6
Sample boxes were prepared for testing by following the prescribed procedure outlined in Method
201A.
Sampling and Analytical Procedures
All test procedures employed were as specified in 40 CFR 60 Appendix A and 40 CFR 51
Appendix M.
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, 40 CFR 51 Appendix
M, and the Quality Assurance Handbook for Air Pollution Measurement Systems.

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, Division of Air Quality
(DAQ) and EPA may have their own personnel to observe all phases including the process.

Facility Location and Description
This test will be conducted to determine the PM10 emissions from the Grain Craft’s “B”- Wheat
Cleaning Baghouse, specifically identified as the Micro Pulsaire MP 160-8 Baghouse, located in
Ogden, Utah.
Test Objective
This test is being conducted to comply with the requirements of the facility’s Approval Order.
This permit requires testing for PM10 emissions from the “B”-Wheat Cleaning Baghouse exhaust
every five years. Testing procedures will include accumulating process and production data as
well as testing for particulate matter emissions using EPA Method 201A.
Previous testing has been done on this source. Stack temperatures varied from 70 to 80 F and
are a factor of weather and season and not process oriented. Integrated gas samples have
demonstrated that the gas is ambient air. With these considerations and as per EPA Method 202
section 1.2(a) it is proposed that testing for condensable particulate matter be omitted.
Testing will consist of three test runs.
Test Schedule
It is planned to complete this testing project March 29-30, 2021. The testing crew will mobilize
the morning of March 29th and begin testing that afternoon if time permits. Testing will
continue March 30th as needed. If necessary, a pretest meeting may be scheduled by EPA,
DAQ, or Grain Craft.
Site Access
The test site is on the building roof which is accessed via OSHA approved stairs and ladders.
Process Data
All operational and instrumentation data will be made available to DAQ personnel. The facility
will run at normal conditions.
Test Procedures EPA Methods 201A
The following specific items will be followed for EPA Method 201A:
1. The stack inside diameter as measured is 28 inches. There are two ports available for
testing. A total of 12 points will be sampled, six per port. Minimum target sampling time
will be 60 minutes; however, stack flow will determine the dwell time at each point and
actual test time. A source schematic drawing is included in Appendix A.
2. Probe/PM10 cyclone blockage effects have been calculated. The cross sectional area of the
PM10 cyclone is 14.5 square inches. The cross sectional area of the B Wheat Cleaning
Baghouse exhaust is 615.8 square inches. The blockage effect is 2.42 percent. Because the
blockage effect is less than 3 percent, no probe blockage factor is needed.
3. EPA Method 2 will be used to determine gas stream velocity. Calibration data for the type
“S” pitot tubes are included with this protocol. Dual inclined/vertical manometers with
graduations in 0.01 inches of water will be used. Previous testing on this baghouse has
shown that the cyclonic flow is less than 20 degrees; however, the absence of cyclonic flow
will be confirmed prior to the test.
4. The exhaust gas is ambient air. TETCO will use a dry molecular weight of 28.84 lb/lbmole
(20.9 % O2, 79.1 % N2) in all calculations.
5. A barometer will be used to measure the barometric pressure. It is periodically checked
against a mercury barometer. Prior to testing it will be checked to assure an accurate
barometric pressure.
3
6. If Method 202 is not required on this source, the probe liners may be stainless steel, Teflon or
borosilicate glass.
7. Because this is a grain elevator the probe will not be heated in accordance with established
EPA guidelines in 40 CFR 60, Subpart DD.
8. Preparation and clean-up by the contractor will be performed in the contractor's testing
trailer. Laboratory work and analysis will be performed by the testing contractor as soon as
possible after all tests have been completed.
9. If plant maintenance or operating problems arise during the test, the test may be stopped.
This determination will be made by Grain Craft representatives or operating personnel in
consultation with agency representatives.
10. Current calibration data is submitted in Appendix A of this protocol. Any equipment
calibration that fall past due prior to the test date will be recalibrated prior to use. Nozzle
calibration will be included on the run sheet for each respective test run. Any calibrations not
included with this protocol, such as new or additional equipment, will be made available to
DAQ representatives upon request.
11. Verbal results will be reported to Tim Becker of Grain Craft. The written report will follow
within 30 days following the completion of the test.

METHOD 5 DRY GAS METER CALIBRATION USING CRITICAL ORIFICES
1) Select three critical orifices to calibrate the dry gas meter which bracket the expected operating range.
2) Record barometric pressure before and after calibration procedure.
3) Run at tested vacuum (from Orifice Calibration Report), for a period of time
necessary to achieve a minimum total volume of 5 cubic feet.
4) Record data and information in the GREEN cells, YELLOW cells are calculated.
