1 SUMMARY OF RESULTS
1.1 INTRODUCTION
Kleinfelder, lnc. (Kleinfelder) conducted Tier 2 landfillgas (LFG) testing at Wasatch lntegrated Waste
Management District's (Wasatch) Davis Landfill (Landfill), located in Layton, Utah, on July 29,2024.
Testing was conducted to evaluate the concentration of non-methane organic compounds (Cr.rr,,roc)
contained in the LFG generated at the Landfill. At the time of this report, WIWMD's current
Title V operating permit (#1100033004) indicates that Subpart XXX is applicable to the facility.
Therefore, this report will refer to Subpart XXX for Cr'rrr,roc monitoring and testing requirements to show
compliance with the updated permit conditions.
The Crur,,roc was obtained using Tier 2 testing methods, as provided in 40 CFR 52, Subpart XXX, Standards
of Performance for Municipal Solid Woste Londfills, and Appendix A, Reference Method 25C,
Determination of NMOC in MSW Landfill Gases. Tier 2 testing is required by
Condition 11.8.2.a.1 of Wasatch's Title V operating permit. A Tier 2 Test Protocol was submitted to Utah
Division of Air Quality (UDAQ on June 27 ,2024. Via letter DAQC-548-24 dated July 2,2024, UDAQ
confirmed approval of the Test Protocol. A copy of the submitted protocol (and UDAQ's confirmation
correspondence) is included as Appendix A.
Testing was arranged and coordinated by Mr. Jesse Simonsen and Mr. Preston Lee of Wasatch. Testing
was conducted in accordance with Subpart XXX and Methods 25C and 3C, and the LFG sampling
procedures are detailed in Section 2.2. Mr. Paul Morris from UDAQ was present during testing

T,2 RESULTS
Three samples were withdrawn from the active landfill gas collection system (LGCS) located upstream of
the flare station. Samples were analyzed by Air Technology Laboratories in accordance with EPA Method
25C and 3C analytical procedures. Sample results yielded the following average Cxy66 v0lue as carbon,
reported as parts per million by volume (ppmv):
o Total sample average Cr.rrraoc ?s carbon = 936.7 ppmv.
The average Clrrraoc ?s carbon was divided by 5, as specified in Condition 11.B.2.a.1 of the Title V permit, to
yield the Crur,.roc ds parts per million by volume (ppmv) as hexane, yielding the following:
r Total sample average Cr.rrrzroc its hexane = 156.1 ppmv.
The site-specific Cr,rrvoc value of 156.1 ppmv may be used by the Landfill for calculation of the annual
NMOC emissions from the Landfill, in accordance with Condition 11.8.2.a.1 of the litle V permit.
Analytical results of Tier 2 testing at the Landfill are summarized in Table L. Summa@ canister data and
the laboratory analytical report are provided in Appendix B. The LFG sampling procedures used are

2 TESTING PROGRAM
2,1, OVERVIEW
Sampling and analysis were conducted in accordance with the Title V permit, NSPS Subpart XXX and Test
Methods 25C and 3C.
The Landfill is comprised of two cells termed the "unlined cell" and the "lined cell." Although not
required by Subpart XXX regulations, the Landfill began operating an active LGCS within the unlined cell
in December 2001. The system has been designed to collect LFG from both the unlined cell and areas
within the lined cellthat contain waste which is at least two years old. The LGCS (in the unlined and
lined cells) consists of 90 LFG wellheads connected to a header pipe that routes the LFG to a flare for
combustion and a pipeline for off-site utilization. Therefore, sample gas collection from (a sampling port
located on) the existing LGCS header pipe upstream of the gas-moving equipment meets the sampling
requirements as allowed by the Title V permit Condition 11.B.2.a.1. The collected LFG is routed via a
header pipe to a flare for combustion.
The gas sampling procedures are presented in Section 2.2.The sampling event was completed on
July 29,2024, at the Landfill.
2,2 LANDFILL GAS SAMPLING PROCEDURES
LFG samples were collected by withdrawing gas directly from the existing LGCS main header pipe,
upstream of the gas-moving equipment. Prior to sample collection, the connective tubing, and a
minimum of two sampling train volumes of gas were purged using a Envision LFG analyzer . LFG was field
screened using the analyzer to measure the concentrations of oxygen, nitrogen, and carbon dioxide.
When the oxygen content was below 5 percent and/or the nitrogen content of the LFG was below 20
percent, the sample was considered representative of the LFG.

&eatn*tt Right stu*
Following the purge and field-screening process, a three-way valve attached to a sampling train was
opened, allowing LFG to flow into the evacuated six-liter Summa@ canister. Sampling rates were
adjusted using needle valve control and monitored using a rotameter incorporated into the sampling
train. Approximately three to four liters of LFG were drawn into each of the four canisters, as measured
by tracking the time and flow rate.
Each canister was leak-checked by the laboratory prior to initial shipment to Kleinfelder. Prior to sample
collection, the initialvacuum pressure in each canisterwas measured and recorded (as inches of
mercury) on the field data sheets. Final vacuum pressures were recorded for each canister following
sample collection.
Canisters were shipped under chain-of-custody to Air Technology Laboratories. Canisters were shipped
under negative pressure to provide a check of the canister integrity upon receipt by the laboratory. A
total of three canisters containing samples were submitted for analysis in accordance with Subpart XXX.
A fourth canister (to be used as a backup in case one of the other three leaked or did not meet quality
assurance parameters) was not needed; therefore, it was not analyzed. The Summa canister field
tracking log is provided in Appendix B.
2,3 LABORATORY ANALYTICAL PROCEDURES
Upon receipt at the laboratory, the vacuum in each canister was measured to check for leakage during
shipment. No leakage was reported from the four sample canisters. Vacuum measurements by the
laboratory are maintained by the laboratory and are only reported if problems are encountered with the
canisters. Canisters were analyzed by Method 25C for Crur,aoc as carbon. NMOC concentrations were
reported as ppmv as carbon. The Cunroc as carbon concentrations were divided by 6 to provide Cpy66 ?s
hexane, as specified by Condition 11.B.2.a.1 of the Title V permit and NSPS Subpart XXX.

As required by Method 25C, samples were also analyzed by Method 3C for nitrogen and oxygen, as a
percentage of the total sample. The nitrogen threshold of 20 percent was not exceeded in any of the
samples, and the corresponding five percent oxygen threshold was also not exceeded. Based on the
oxygen concentration below five percent, ambient air intrusion did not appear to be present, and the
sample was considered representative of the LFG. The nitrogen and oxygen content of each of the
composite samples are summarized in Table 1 and are also provided in Appendix B.

3.1 DATA COLLECTION
A Summa Canister Sampling Log was completed in the field to track canister usage and sampling activity.
Samples were field screened with the LFG analyzer to verify the LFG content prior to sample collection.
Canister leak-check records were maintained to verify the integrity of the Summa canisters throughout
the shipment procedures. The Summa Canister Sampling Log and Field Form is included in Appendix B.
General ambient weather conditions were also recorded on the form during the testing.
3.2 SUMMA CANISTERS
Vacuum pressures of the Summa canisters were recorded prior to and following sample collection, as
well as upon receipt by the laboratory prior to performing sample analysis in order to verify integrity of
the samples. lnitial, final, and laboratory-receipt canister pressures (recorded in inches of mercury [Hg])
were recorded by Kleinfelder and Air Technology Laboratories and are provided on Table 2. All
four canisters were received at the laboratory under negative pressure. Although four canisters were
shipped to the laboratory under chain-of-custody documentation, only three canisters were analyzed, as
previously discussed.

Based on the data in Table 2, no leaks occurred during sample shipment. Higher laboratory receipt
pressures as compared to pressures recorded by Kleinfelder before shipment are due to differences in
altitude and corresponding atmospheric pressures between Layton, Utah (4,500 feet above sea level),
and Air Technology Laboratories located in City of Industry, California (150 feet above sea level). Field
data, including gas screening results and Summa@ canister controlforms, are provided in Appendix B.
3.3 METHOD 25C
Method 25C requires a daily calibration of the gas chromatograph (GC), as well as a daily calibration
blank. These procedures were completed by the laboratory, as required. Sample analysis data is
provided in Appendix A.
3.3.L Method 3C
Method 3C is referenced by Method 25C as the required method by which to analyze fixed gases of
nitrogen and oxygen as a percentage of the total sample. Method 3C requirements are the same as
those for Method 25C, including a daily GC calibration and a daily calibration blank. The Method 3C
calibration requirements were completed by Air Technology Laboratories, as detailed in the analytical
report in Appendix B.

INTRODUCTION
The Davis Landfill(Landfill), located at1997 East 3500 North in Layton, Utah, is an active Class I
municipal solid waste (MSW) landfill that is owned and managed by Wasatch lntegrated
Waste Management District (Wasatch). The Landfill covers approximately 359 acres, has a design
capacity of approximately 13.8 million cubic yards, and has an active landfill gas collection system
(LGCS).
Wasatch has contracted Kleinfelder, lnc. (Kleinfelder) to provide Tier 2 emissions testing services at the
Landfill. The facility operates under Title V Operating Permit (#1100033003), issued by Utah Division of
Air Quality (UDAa).The testing will be conducted to assess the site-specific concentration of non-
methane organic compounds (NMOC) within landfill gas (LFG) generated at the Landfill. The results of
this testing will be used to estimate the annual NMOC emission rate from the Landfill, as required by the
Landfill's Title V Operating Permit and federal New Source Performance Standards (NSPS) 40 CFR Part
60, Subpart XXX, "Stondords of Performonce for Municipol Solid Woste Londfills That Commenced
Construction, Reconstruction, or Modificotion After luly L7, 20L4." Sampling and analysis will be
conducted according to 40 CFR Part 60 Appendix A, Methods 25C and 3C.
Testing for NMOC was previously completed on October 4, 2023, under a test protocol (dated August
28,2023), approved by UDAQvia DAQC-960-23, dated September 13,2023. Wasatch submitted the
N MOC test report to UDAQ on December 5,2023. Due to concerns about representativeness of the
landfill gas that was tested on October 4,2023, Wasatch proposes to retest for NMOC and is presenting
this testing protocol to that effect.

TEST PROGRAM
2,I WASTE AGE AND SAMPLING LOCATION
The Davis Landfillis comprised of two cells termed the "unlined cell" and the "lined cell." Although not
required by Subpart XXX regulations, the Landfill began operating an active LGCS within the unlined cell
in December 200L. The system has been designed to collect LFG from both the unlined cell and areas
within the lined cell that contain waste which is at least two years old. The LGCS (in the unlined and
lined cells) consists of 90 LFG wellheads connected to a header pipe that routes the LFG to a flare for
combustion and a pipeline for off-site utilization. Therefore, sample gas collection from (a sampling port
located on) the existing LGCS header pipe upstream of the gas-moving equipment meets the sampling
requirements as allowed by Subpart XXX, 60.764(a)(3). See Appendix A for a site map showing the
sampling location.
The methane, nitrogen, oxygen, and carbon dioxide content of the gas will be screened using a portable
landfill gas analyzer prior to sampling to ensure that samples will meet the quality control (QC) criteria
of EPA Method 25C.
Gas samples will be collected in four, six-liter Summa'canisters. Filled canisters will be shipped to
Air Technology Laboratories under chain-of-custody for analysis by EPA Methods 25C/3C.lf canisters
pass laboratory and Test Method quality assurance/quality control (QA/QC), the results of the analyses
will be used for calculation of the site-specific Cruvroc.
2.2 EPA METHOD 25C
Sample collection and analysis for estimation of NMOC in LFG will be conducted in accordance with EPA
Method 25C. Sample gas will be withdrawn from the main LGCS header via a stainless-steel flow control
manifold containing a fine-flow controller, a flow-indicating rotameter, and a three-way purge/sample
valve. The Summao canister will be attached to the sampling train behind the purge/sample valve. Prior
to sampling, the calibrated landfillgas analyzerthat is connected to the purge side of the three-way
valve will be used to draw LFG through the sampling port and tubing. A minimum of two sample tubing
volumes of LFG will be purged through the sampling train prior to collection of the samples. Prior to, and
after each sampling, the tubing, and portion of the flow control manifold will be purged with helium,
which is an inert, non-reactive gas. A sampling schematic is provided in Appendix B.

&tttl*" 'ts'btu*t
The landfill gas analyzer will be used to assess if the nitrogen content of the LFG is below 20 percent; if
nitrogen content remains above 20 percent, an alternative QC requirement of oxygen content less than
5 percent is allowed by EPA Method 25C.
An LFG sample, approximately four liters in volume, will be withdrawn from the sampling port located
on the LGCS header at the rate of approximately 0.50 liters per minute through the sampling train into a
six-liter Summa'evacuated canister. The canisters are preloaded by the laboratory with approximately
one liter of helium, which combined with the effect of the Landfill altitude, reduces the effective
canister volume to approximately four liters. A total of four canisters will be filled with LFG during the
sampling event. The sampling train will be purged with helium between each sample to prevent
cross-contamination between samples.
Summao canisters are cleaned, polished, and leak-checked prior to shipment from the laboratory.
Vacuum readings will be recorded prior to and immediately after each sample, and again prior to
shipment back to the laboratory. Upon laboratory receipt, the vacuum readings in the canisters will be
recorded to assess whether leaks have occurred during shipment. This procedure is discussed further in
Section 3.3 of this Test Protocol.
Filled sample canisters will be shipped to Air Technology Laboratories under chain-of-custody. Three of
the sample canisters will be analyzed, as required by Method 25C, and the fourth (backup) sample
canister will be held in abeyance by the laboratory and only analyzed if one of the initial three canisters
fails laboratory or Method QC parameters.
Each sample will be analyzed for NMOC in triplicate, as required by the Method, with the resulting
average representing the average Crurr,1oc of the sample. The Crr'aoc is reported as carbon. Analytical
results will be divided by six and reported as hexane for calculation of NMOC emissions from the landfill
facility as stipulated by $60.764 a(3).
2,3 EPA METHOD 3C
EPA Method 3C will be used primarily to evaluate the percent nitrogen and oxygen in each sample. The
presence of excess nitrogen or oxygen in a sample indicates infiltration of ambient air into the gas
sample. EPA Method 25C stipulates that the nitrogen content must be less than 20 percent for the
sample to be acceptable. Because prior testing has indicated that LFG may contain in-situ nitrogen levels
above 20 percent, EPA allows an alternative requirement of less than 5 percent oxygen if nitrogen
exceeds the 20 percent threshold. Preliminary nitrogen and oxygen screening will be performed using

QUALITY ASSU RANCE/qUALITY CONTROL
3.1 CALIBRATION
The landfill gas analyzer will be calibrated daily for methane and oxygen. Documentation of the
calibration will be recorded and maintained by Kleinfelder and made available upon request.
3.2 DATA COLLECTION
Field data sheets will be maintained throughout the sampling event. The following information will be
recorded for each sample:
Sample identification number,
Sample location,
Pre- and post-sample canister pressure checks,
Canister serial number, and
Sampling start and end times.
Samples collected will be handled under general chain of custody requirements, in accordance with
standard environmental sampling protocol.
3.3 SUMMA CANISTERS
Summao canisters will be certified clean, in accordance with the patented Summa@ process, prior to
shipment by Air Technology Laboratories. Documentation of canister cleanliness and regular canister
blank test audits are kept on file by the laboratory. Canisters are shipped under approximately
-30 inches of mercury (Hg)vacuum (effectively -18 to -21 inches Hg at the Landfill's altitude).
The canister vacuum will be recorded prior to and immediately after sampling. Upon laboratory receipt,
the laboratory personnel will record vacuum readings in the canisters to check that no leaks have
occurred during shipment. Sample containers must maintain a negative pressure, orvacuum,
throughout the sampling and analysis procedure for sample integrity verification. We will attempt to
ship the canisters back to the laboratory on the sampling day. lf canisters are shipped the same day as
the sampling, then the sampling pressure recorded at the end of sampling will be considered sufficient
for the recorded pre-shipment pressure. lf canisters are held for more than one day after sampling, the

canister vacuum will be recorded again prior to return shipment to the laboratory. Appropriate data
sheets showing recorded canister pressures will be included with the test report. Each canister has a
unique serial number, which will be recorded on the appropriate sampling form, as well as on the
cha in-of-custody.
3.4 LABORATORYANALYSIS
Method 25C and Method 3C each have QA/QC requirements pertaining to gas chromatograph operation
and calibration. The selected analytical laboratory will adhere to QA/QC requirements, as specified by
the methods. Relevant QA/QC data will be included in the test report.
3.5 BACKUP SAMPLE
An LFG sample will be collected in one extra Summao canister and kept in reserue in case a replacement
canister is needed. The backup canister will also be shipped under chain-of-custody but will be held in
abeyance without analysis by the laboratory. lf one or more of the original three sample canisters fails
QC parameters due to intrusion of ambient air (i.e., nitrogen greater than 20Yo or oxygen greater than
5%), then the backup canister will be considered as a replacement for analysis.

Qcgr = annual methane generation in the year of the calculation (m3 /year)
i = 1-year time increment
n = (year of the calculation) - (initial year of waste acceptance)
j = 0.1-year time increment
k = methane qeneration rale (year-1 \
Lo = potential methane generation capacity (m'tMg)
Mi = rnsSs of waste accepted in the ith yeat (Mg)
tij = age of the jrh section of waste mass M, accepted in the ith year
(decimal years, e.9., 3.2 years)
LandcEM is based on a firsl-order decomposition rate equation for quantifying emissions from the decomposition of landfilled waste in
municipal solid waste (MSW) landfills. The software provides a relatively simple approach to estimating landfill gas emissions. Model defaults
are based on empirical data from U.S. landfills. Field test data can also be used in place of model defaults when available. Further guidance on
EPA test methods, Clean Air Act (CAA) regulations, and other guidance regarding landfill gas emissions and control technology requirements
can be found at http ://www.epa. gov/ttnatwO 1 /landfi ll/landfl pg. htm l.
LandGEM is considered a screening tool - the better the input data, the better the estimates. Often, there are limitations with the available
data regarding waste quantity and composition, variation in design and operating practices over time, and changes occurring over time that
impact the emissions potential. Changes to landfill operation, such as operating under wet conditions through leachate recirculation or other
liquid additions, will result in generating more gas al a faster rate. Defaults forestimating emissions forthis type of operation are being
developed to include in LandGEM along with defaults for convential landfills (no leachate or liquid additions) for developing emission
inventories and determining CAA applicability. Refer to the Web site identified above for future updates.
