INTRODUCTION

Test Purpose

This testing project was conducted to determine the NOx and CO emissions from the Waukesha
923 kW Lean Burn Engine located at the North Davis Sewer District (NDSD) facility. Emissions
are expressed in terms of pounds per hour (lb/hr) and grams per brake horsepower hour (g/bhp-hr).

Test Location, Type of Process

NDSD operates a water treatment facility located at 4252 West 2200 South, Syracuse, Utah. Part
of the water treatment includes collecting digester gas which is prepared for use as a fuel for
engines at the facility. Figure 1 in Appendix D is a schematic of the engine's exhaust stack.

Test Dates

All testing was completed September 11, 2024. A fourth test run was completed because the
second Method 4 test run sample volume was only 17.512 dry standard cubic feet (dscf), which
was less than the 21 dscf required by Method 4.

Pollutants Tested and Methods Applied

The tests were a determination of NOx and CO emissions in accordance with EPA Methods 4, 7E,
and 10. One Method 4 test run was completed for each Method 7E and 10 test run as directed by
Kyle Greenburg of the Utah Department of Environmental Quality, Division of Air Quality
(UDAQ).

Process Data

The process was operated according to standard procedures. Engine power output was recorded
on the Method 4 Field Data Sheet during each individual run. A summary of the production data
is also found in Appendix D.

Gas Analyzer Performance Criteria

The NOx and CO gas analyzers met all bias and calibration checks criteria as specified in the
Federal Register. The Method 3A gas analyzers met all bias and calibration checks criteria. The
results of all checks are on the gas analyzer field data sheet in Appendix B.

SAMPLING AND ANALYSIS PROCEDURES

Sampling Port Location

The stack diameter was 13 inches. Sample ports were located 12.31 diameters (160 inches)
downstream from the last disturbance and approximately 8.0 diameters (104 inches) upstream
from the nest disturbance. Two, four-inch diameter ports were available for testing.

Sampling Point Location

Table II shows the sampling point distance from the inside wall according to EPA Method 1.
Each point is marked and identified with a glass tape wrapping and numbered. These points are
determined by measuring the distance from the inside wall and adding the reference (port)
measurement.

A stratification check was conducted according to Method 7E, section 8.1 using three sample
points. The results of the stratification check show that all sample points were within 5 percent of
the mean and the stacks were considered unstratified. One sample point was used for the
remainder of the Methods 7E and 10 testing.

Sampling Train Description

To determine the actual emission rates for these stacks 40 CFR 60, Appendix A, EPA Methods 4,
7E, and 10 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 Method 4 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 Method 4 sampling train sketch is found as Figure 2 in Appendix E.

6

The sample box was prepared for testing following the prescribed procedure outlined in Method 4.

The NOx analyzer was an Horiba Model CLA-510SS Chemiluminescence unit. The analyzer
span was 0-234 ppm. EPA Protocol 1 gases were used as the span and mid-range for the NOx
analyzer during all tests; their respective concentrations were 234 and 126 ppm. Dry nitrogen
was used as the zero gas for the analyzer.

The CO analyzer was a Horiba, Model VIA 510 NDIR. The analyzer span was 0-920 ppm. EPA
Protocol 1 gases were used as the span and mid-range for the CO analyzer during all tests. Their
respective concentrations were 920 and 481 ppm. Dry nitrogen was used as the zero gas for the
analyzer.

The CO2/O2 analyzer was a CAI Model ZRE, dual gas unit. The NDIR CO2 analyzer span was
20.41 % with calibration gases of 20.41% and 9.75% CO2. The electrochemical cell O2 analyzer
span was 20.73 % with calibration gases of 20.73% and 9.77 % O2. EPA Protocol 1 gases were
used as the span and mid-range for both analyzers. Dry nitrogen was used as the zero gas for the
analyzer.

The gaseous analyzer sampling train was constructed with a stainless steel sampling probe about 2
feet long. The heated sample line between the sampling probe and gas conditioner was Teflon.
The sample conditioner utilized permeation tubes to dry the sample gas. Purge air to the tubes
whisks away any collected water vapor. Sample lines from the gas conditioner to the analyzer
were Teflon. A sampling train sketch appears as Figure 3 in Appendix E.

Sampling and Analytical Procedures

All sampling and analytical test procedures employed were as specified in 40 CFR 60 Appendix A,
Methods 4, 7E, and 10.

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.

Fill a Tedlar bag approximately half full with either ambient air, pure oxygen, or an oxygen standard gas with at
least 19.5 percent by volume oxygen content. Fill the remainder of the bag with mid-level NO in nitrogen
calibration gas...
Immediately attach the bag to the inlet of the NOx analyzer (or external converter if used)… Measure the NOx
concentration for a period of 30 minutes. If the NOx concentration drops more than 2 percent absolute from the
peak value observed, then the NO2 converter has failed to meet the criteria of this test. Take corrective action.
The highest NOx value observed is considered to be NOxPeak. The final NOx value observed is considered to be
NOxFinal.

Engine #3 Lean Burn Engine
Date:Wednesday, 28 August, 2024 9:55:00 AM
Kyle,

It looks like we will be testing the NDSD Waukesha on the 11th of Sept.
In preparation for that, I had a question about calculating the NOx and CO g/bhp-hr values. 
Can we use the engine’s efficiency rating to calculate the engine bhp from the recorded
engine power output?  In the past we have always used the engine power output in kW andused that as the bhp in the denominator of the equation.  This is conservative and over
calculates the engine emissions because the actual engine bhp would be greater than the
recorded power output of the engine.

I believe using the engine efficiency would be a better approximation of the actual engine
bhp.  If that will not work, is there another, simple way to get the engine bhp?

Thanks,
Dean Kitchen

Thanks Myron,

I also looked into the required time length for the three runs.  I know in the past that
shorter runs were allowed, but I have been diving into state rules, the Approval Order,
and 40 CFR Part 63 Subpart ZZZZ and it looks like to be compliant with the state rules,
three 1-hour runs will be required for this internal combustion engine.  A new pretest
protocol will not need to be resubmitted since the run times are not defined in theprotocol, so that protocol will work again for when the test is rescheduled. I believe the initial mistake in allowing the runs to be less than a hour was mistakenwith the run lengths allowed for turbines in 40 CFR Part 60 SubpartKKKK https://www.ecfr.gov/current/title-40/part-60/subpart-KKKK#p-60.4400(b)  But
since all these Cogens are Internal Combustion engines, 1-hour runs are required to
be in compliance with the state and any future EPA audits as well. 

Sorry for the less than ideal news, but it'll ensure that everything is in compliance,

Hi Myron,

I just wanted to follow up for tomorrow. Paul Bushman and Connor Kijowski will not
be able to make it for tomorrow, but I'll still be observing.  If everything is still on
schedule, I am Planning on being onsite around 7:15am and will stick around
probably for 2 of the stack test runs.  My work cell # is 385-306-6533 in case anyone
needs to get a hold of me in the AM tomorrow.

Thanks for your help in getting this set up,

Davis Sewer District’s Cogeneration Engine #3 Lean Burn Engine

Mr. Bachman and Mr. Dean:
 The DAQ would like to observe the upcoming stack teston the North Davis Sewer District’s Cogeneration Engine#3 Lean Burn Engine that is scheduled to be conductedon May 6-7.
 For the inspectors there will be myself, Paul Bushmanand Connor Kijowski. Really the purpose of this
observation is to get Connor (new to inspecting stack
tests) familiar with the observation process.  Dean I'll
confirm with you late next week on timing, but ideally we
would like to be there to observe the initial calibration and
leak checks and then if everything is going smoothly I'd
imagine we'll probably leave after run 2.

Myron please let me know if this scheduling will work and
if you could let me know what the required PPE is for the
site.

Thanks for your help in getting this set up,
Kyle Greenberg

COMPLIANCE EMISSION TESTING PROTOCOL
FOR NOx AND CO EMISSIONS AT
NORTH DAVIS SEWER DISTRICT (NDSD)
SYRACUSE, UTAH
Waukesha 923 kW Lean Burn Engine
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.
Company
NDSD
4252 West 2200 South
Syracuse, UT 84075
Contacts
Myron Bachman [phone]
Test Contractor:
TETCO
391 East 620 South
American Fork, UT 84003
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.
Potential Hazards
Moving Equipment No
Hot Equipment Yes
Chemical Chlorine on site
Other Biological. Wash hands frequently and eat only in
designated areas.
Quality Assurance
All testing and analysis in these compliance tests will be conducted according to Methods 1-4,
7E, 10, and appropriate sections of the EPA Quality Assurance Handbook for Air Pollution
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.
