INTRODUCTION
Test Purpose and Location
This test was conducted to determine the PM10 particulate matter emissions from the exhaust of
the Central Dust Collection Scrubber, which was in compliance with Approval Order DAQE – AN0107220016-16, dated March 23, 2016. PM10 emissions were measured using EPA Method 5 instead of EPA Method 201A because EPA Method 201A is not possible on a source with entrained water droplets. Emissions are calculated in grains per dry standard cubic foot and
pounds per hour.
Cargill Salt’s Grantsville plant is located approximately one-half mile west of the Rowley Junction (Exit 77) on I-80, in Tooele County, Utah. The facility produces salt and salt products.
Test Dates The crew mobilized and set up equipment December 11, 2023; no testing was conducted on this date. Three Method 5 test runs were conducted on December 12, 2023.
Pollutants Tested and Methods Applied Particulate matter was measured in accordance with 40 CFR 60, Appendix A, Method 5.
Test Participants Cargill Salt Jackson Nash Samuel Graham
TETCO Dean Kitchen Reed Kitchen Xuan Dang
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.

Percent Isokinetic Sampling
Each of the tests used for compliance were isokinetic within the ±10% criterion specified in the
Federal Register. Isokinetic values for each test run are presented in Table II. Table II. Percent Isokinetics

SAMPLING AND ANALYTICAL PROCEDURES
Sampling Port Location
The Central Dust Collection Scrubber stack inside diameter was 36 inches. The ports were located 2.0 diameters (72.0 inches) upstream from the next disturbance and 7.2 diameters (258 inches) downstream from the last disturbance. There were two, 4-inch diameter ports available for testing.
Sampling Point Location Table III shows the distance of each sampling point from the inside wall. Each point was
marked and identified with glass tape wrapping and numbered. 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 from Inside Wall (inches)
1 4.58 2 8.26 3 13.66
4 28.34
5 33.74 6 37.42
Sampling Train Description
The sampling train was made of inert materials, (i.e., Teflon, stainless steel, glass, etc.) according to 40 CFR 60, Appendix A, Method 5, to prevent sampled gas and particulate interference. The stack analyzer used to conduct Method 5 was constructed to meet the specifications outlined in the CFR. The temperature sensors are 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. Sampling and Analytical Procedures
All test procedures employed were as specified in 40 CFR 60 Appendix A, Method 5.

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 and the Quality Assurance
Handbook for Air Pollution Measurement Systems.

COMPLIANCE EMISSION TESTING PROTOCOL FOR PM10, AND CONDENSABLE PARTICULATE MATTER
CARGILL INCORPORATED, SALT DIVISION, GRANTSVILLE, UTAH CENTRAL DUST COLLECTION SYSTEM SCRUBBER
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. Company Contacts Cargill Incorporated, Salt Division Carmen Ontiveros 661 586-1240 15100 West Rowley Road Grantsville, Utah 84029
TETCO Dean Kitchen 801-492-9106 391 East 620 South American Fork, Utah 84003
Facility and Location Cargill Incorporated, Salt Division is located approximately 40 miles west of Salt Lake City, Utah on the north side of I-80 at Exit 77 along Rowley Road. The facility produces salt and salt
products. The source to be tested is the Central Dust Collection System Scrubber exhaust. Test Objective
The test objective is to comply with the facility’s approval order number DAQE- AN0107220016-16 dated March 23, 2016. Testing procedures on the Central Dust Collection System Scrubber will include accumulating process and production data as well as testing for PM10 particulate matter emissions using EPA
Method 5 with all captured matter counted as PM10. Previous stack flow and temperature measurements on the Central Dust Collection System have demonstrated stack temperatures are below 85 °F. Stack temperatures are a factor of the season and weather and not process oriented. An integrated gas sample has also demonstrated that the
gas is ambient air. With these considerations and as per EPA Method 202 section 1.2(a), it is
proposed that condensable particulate matter testing is not completed on this source.

Test Schedule
It is planned to complete this testing project the week of December 11, 2023.
Site Access
The testing site is accessed by man-basket.
Potential Hazards Moving Equipment - yes
Hot Equipment - No Chemical - No Other - Yes Elevated Work, Noise Process Data All operational and instrumentation data will be made available to DAQ personnel. The facility will run at normal conditions.
Quality Assurance All testing and analysis in these tests will be conducted according to 40 CFR 60 Appendix A, Methods 1-5.
Reporting Reporting will be prepared by the testing contractor according to EPA Quality Assurance
Guidelines. A complete copy of raw data and test calculations summary will be included in the reports. All process and production data will be recorded by Cargill Incorporated, Salt Division personnel for inspection by DAQ and EPA, if requested. Test Procedures Particulate matter testing will be conducted on the Central Dust Collection Scrubber stack according to EPA Method 5. The reason for using EPA Method 5 instead of Method 201A for PM10 is because there are water droplets in the stack exhaust. Specific procedures are as follows:
1. The sample locations and the number of sample points will comply with the requirements
3
of EPA Method 1.
The Central Dust Collection system (Venturi Cyclonic SEP scrubber-dry cyclone)
exhaust has an inside diameter of 36 inches. The ports are located 72 inches (2.0 diameters) upstream from the next disturbance and 258 inches (7.17 diameters) downstream from the last disturbance. There are two, 4-inch ports available for testing.
2. EPA Method 2 will be used to determine the gas stream velocity. Type “S” pitot tubes
will be used with a Cp factor of 0.84. Dual inclined/vertical manometers with graduations of 0.01 inches of water will be used. If the flows are below .25 inches of water a more sensitive manometer will be used. The graduation marks on it are .005 inches of water. Direction of gas flow will be checked for cyclonic flow prior to testing. Previous testing has demonstrated that the cyclonic gas flow has averaged over 20 degrees. Due to this
condition straightening vanes have been installed. 3. Test run time will be at least 60 minutes for the Method 5 tests. Sample volume will be a minimum of 30 dscf.
4. TETCO will use a dry molecular weight of 28.84 lb/lbmol (20.9 percent O2, 79.1 percent N2) in all calculations. 5. EPA Method 4 will be followed to determine the gas stream moisture content.
6. Probe liners will be 316 stainless-steel for all Method 5 tests. 7. The glass fiber filters used will meet the requirements of EPA Method 5. 8. 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. 9. All current calibration data is submitted with this protocol, except 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.
10. Any necessary preparation and clean-up by the contractor will be performed in the
contractor's sampling trailer or a clean area on Cargill’s property. The laboratory and analysis work will be done by the contractor as soon as possible after the test project at 391 East 620 South, American Fork, Utah.
11. Verbal results will be reported to David Gibby of Cargill Incorporated, Salt Division.
The written report will follow within 30 days following the completion of the test. If maintenance or operating problems arise during the test, the test may be stopped. This
determination will be made by Cargill Incorporated, Salt Division representatives and operating personnel in consultation with DAQ representatives.
