Project Organization and Responsibility
The following personnel and the testing contractor are presently anticipated to be involved in the
testing program. The Utah Division of Air Quality (DAQ) may have their own personnel to
observe all phases including the process.

Test Contractor:

Dean Kitchen 801- 492-9106
Facility Location and Description
NDSD operates a water treatment plant in Syracuse, Utah. The process includes collecting
digester gas which is prepared as a fuel gas for onsite engines.
Test Objective
This test is being conducted to comply with the testing requirements of the Waukesha 7100GL,
923 kW engine. The engine is to be tested at least once every 5 years for NOx and CO emissions.
The results shall be reported in terms of pounds per hour (lb/hr) and grams per brake horse-
power-hour (g/bHp-hr). Testing is to be conducted according to the principals of EPA Methods
1-4, 7E, and 10.
Test Schedule
It is planned to complete all testing May 6-7, 2024. The test crew will set up the testing
equipment May 6th and then begin testing if time and production permits. If needed, testing may
be conducted on May 7th. The testing crew will take preliminary velocity and cyclonic flow
measurements prior to beginning the stack test. If desired a pretest meeting may be scheduled by
DAQ or NDSD.
Operational Data and Instrumentation
The engine will operate normally during the test project. All pertinent process data will be made
available to DAQ personnel.
Test Procedures
Three test runs will be completed on the exhaust stack. Stack testing will be EPA Methods 1-4,
7E, and 10 as specified in 40 CFR 60, Appendix A. One Method 4 test run may span up to three
Method 7E and 10 test runs. Specific procedures are as follows:
EPA Methods 1-4
1.The stack inside diameter is 13 inches. Sample ports are located 160 inches downstream
and approximately 104 inches upstream from any flow disturbance. It is planned to
sample four sample points per port (eight total points). The number of sample points is
based upon Method 1 for a nonparticulate traverse.
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 necessary a more sensitive manometer with
graduations of 0.005 may be used. The absence of cyclonic flow will be verified prior to
beginning the test.
3.EPA Method 3A will be used to measure the CO2 and O2 concentrations to determine the
gas stream dry molecular weight. These samples will be taken with the NOx and CO
sampling train. Method 3 maybe used as a backup for Method 3A.
4.EPA Method 4 will be followed to determine the gas stream moisture content. Test run
time and sample flow rate will be sufficient to sample at least 21 dscf. One Method 4
may span up to three Method 7E and 10 test runs.
5.Probe liners will be 316 stainless steel.
6.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.
7.Calibration data is submitted with this protocol. Any calibration that is not current will
be re-calibrated prior to the test dates.
8.Any necessary preparation and clean-up by the contractor will be performed in the
contractor's sampling trailer or a clean area on NDSD property.
9.Verbal results will be reported to NDSD on site. The written reports will submitted
within 30 days following completion of the tests.
Gaseous Analyzer Measurements
Gaseous analyzers will be used to measure the CO2/O2, NOx and CO concentrations levels
according to EPA Methods 3A, 7E, and 10 respectfully. The gaseous analyzer measurements
will be taken simultaneously with EPA Methods 1-4. EPA Protocol 1 gases will be used as a
standard for all analyzers. Bias checks, calibration drift, zero drift and calibration error will
follow the specified guidelines of EPA Method 7E.
The gas analyzer sampling train will consist of the following: an in-stack glass fiber filter,
heated stainless steel probe, Teflon heated sampling line to the water removal system, water
removal system, Teflon transport lines, gas manifold, and out of stack Teflon filter after the gas
manifold but prior to analyzer. The sampling train is built such that the sampled gas only comes
in contact with inert materials, i.e., Teflon, stainless steel, and glass.
A data logger will be used to provide a recorded gas concentration measurements that will be
averaged on a minute basis.
A stratification check will be performed to determine the number and location of the gaseous
analyzer sample points.

Quality Assurance
All testing and analysis in these compliance tests will be conducted according to Methods 1-4,

Measurement Systems Volume III.
Reporting
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
DAQ.

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.
