Subject: Review of Tier II NMOC test report and annual NMOC Emissions
Estimate report dated January 29, 2024, and February 13, 2024.

On January 30, 2024, and February 13, 2024, the Utah Division of Air Quality (DAQ) received a Tier II
test report and 5-year NMOC amended Emissions Estimate for landfill gas emissions testing conducted at
the Bountiful City Landfill located in West Bountiful, Davis County, Utah. Testing was performed on
November 30 through December 1, 2023, to determine compliance with Title V operating permit
condition II.B.1.a, II.B.1.a.1(c), 40 CFR 60 Subpart WWW, Sections 60.750-60.759, and 40CFR Part 62,
Subpart OOO for NMOC emissions. Test samples were collected from 32 sites 5-15 feet below the
landfill cover using a hydraulic, direct push drilling platform. Samples were extracted from each of the 32
sampling probes and composited into eight Summa canisters. The sites were in landfill areas that have
contained waste for two years or longer. Bountiful City Landfill is an active Class I MSW landfill. The
landfill emissions testing report and annual NMOC emissions estimate appear to use the specified
formulas and testing methods as outlined in the Tier II testing requirements in the above regulations. The
DAQ test report evaluation is as follows:

The concentrations of nitrogen and oxygen in the gas stream appear to be acceptable. RM 25C was used
to determine NMOC emissions. Annual emissions were currently reported to be 4.704 Mg for the
calendar year 2023. Calculations used EPA LandGEM version 3.02, the test result for NMOC
concentration of 98 ppmv as Hexane and an estimated waste acceptance rate of 100,000 Mg/year for the
next five years (2023-2027) with the following tabulated results.

NMOC 5.194 Mg/year 2027 34/50 Mg/year*

All samples had either O2 <5% and/or N2 <20% or an N2/O2 ratio >3.71 for landfills receiving < 20 inches
of annual precipitation.

*Subpart OOO 3-year and Subpart WWW 5-year limits that activate installation of a control device

DEVIATIONS: No deviations were noted.

CONCLUSION: The estimated NMOC emissions are projected to be below 50 Mg/year
(Subpart WWW's threshold) and below 34 Mg/year (Subpart OOO's
threshold) for the years 2023 through 2027. Actual waste acceptance
over the next five years is not expected to exceed 100,000 Mg/year, as
stated in their report. Based on the results, Bountiful City Landfill plans
to repeat the Tier II testing in calendar year 2028, and another five-year
estimate of NMOC emissions report will be generated.

The NMOC emissions factor appears to be acceptable. Testing appears to
have been in compliance with the applicable test methods and QC
requirements at the time of testing. Projected emissions are less than the
34/50 Mg/year triggers.

RECOMMENDATION: The test result for NMOC of 98 ppmv as Hexane appears to be
acceptable.

HPV: No.

Dear Mr. Bird:
According to the Utah Administrative Code and Bountiful City's Title V Operating Permit the city
has chosen determine the site-specific non-methane organic carbon (NMOC) emission rate using
the Tier ll process. The mass NMOC emission rate has been determined to be substantially less
than 50 Mg per year and much less than the pending threshold of 34 Mg per year, therefore the
site-specific NMOC emission rate is being re-tested every five years. The city contracted with
Hansen Allen & Luce Engineers to prepare a test protocol and perform the sampling and testing.
The Sampling Workplan for Tier ll Landfill Gas Testing was submitted to the Division of Air Quality.
The workplan was reviewed and found acceptable by the Division as explained in a letter dated
November L6,2023. The sampling was performed at the facility November 30 - December 1,
2023 according to EPA Methods 25C and 3C. During the sampling, the facility was operating under
normal operating conditions and in accordance with requirements of the city's Title V Operating
Permit.
The site-specific NMOC concentration found through this Tier ll sampling and testing event is 98
ppmv as hexane. This value for NMOC concentration will be used for estimating emissions from
the facility. A complete report of the Tier ll testing results is attached. A certification by a
responsible official is also included.

Bountiful Sanitary Landfi ll Tier ll Test Report
CHAPTER 1 . INTRODUCTION
!NTRODUCTION
Bountiful City selected Hansen, Allen, & Luce, lnc. (HAL) to conduct the Tier ll landfill gas testing
services for the Bountiful Sanitary Landfill. Under the New Source Performance Standards
(NSPS) federal regulations (40 CFR Part 60, Subpart W1/VW), the Bountiful Sanitary Landfill is
currently required to test and estimate the non-methane organic compound (NMOC) rate every
five years. The results of this Tier ll landfill gas test will be used by Bountiful City Engineering to
calculate the annual NMOC emissions rate to determine if the threshold emission rate for installing
a landfill gas collection and control system is triggered.
HAL completed the Tier ll landfill gas testing on December 1,2023 and received preliminary
analytical results on December 22, 2023. Chapter 2 contains descriptions of the field activities
and Chapter 3 contains analytical and quality control results for this testing event.
LANDFILL DESCRIPTION
The Bountiful Sanitary Landfill is a Class I landfill operating under a Title V Operating Permit
(#1100113004 dated February 27,2019) located at 1300 West Page Lane in West Bountiful,
Utah. The Landfill has been in operation for 37 years, having first accepted waste in 1987 and
becoming permitted in 2000. The historic and active landfill area is about 100 acres. About 40
acres (16 hectares) of the landfill contains waste of age greater than two years. About 59 acres
of the historic landfill contains primarily ash from historic open burning of waste, which is mostly
located in the South Cell. This material has been tested and shown to produce no methane, so
NMOC rate testing is not appropriate in this portion of the landfill (40 CFR 60.754(aX3)). The
Bountiful Sanitary Landfill and the portions which are not methane-producing are shown in Figure
1.
Bountiful Sanitary Landfill 1-1 Tier ll Test Report
CHAPTER 2 - FIELD ACTIVITIES
SAMPLING LOCATIONS
32 locations within the area of the landfill containing waste for 2 or more years were sampled for
the Tier ll Testing. Sample locations were laid out in a grid pattern over a current contour map of
the landfill. Actual collection points were occasionally adjusted by field representatives to
compensate for poor access, low quality gas, or safety concerns, as necessary. These locations
are shown in Figure 1.
SAMPLING PROCEDURES
Samples were collected according to EPA methods 25C and 3C. HAL utilized a hydraulic, direct-
push drilling platform to place landfill gas sampling probes to depths of 5-15 feet below the existing
ground level. The probes were sealed against ambient air intrusion into the sampling space. The
landfill gas samples were collected through a post-run tubing system.
A hollow steel drive rod with a sampli4g head was advanced to the desired depth by direct-push
methods, the expendable drive point was ejected, and the probe was retracted approximately six
to twelve inches to create an airtight headspace . ATe-inch polyethylene tube was inserted through
the hollow steel drive rod and connected to the sampling head with an airtight threaded fitting.
The pre-screening was performed by using a Landtec GEM5000 portable landfill gas analyzer.
The landfill gas analyzer was be connected to the %-inch polyethylene tubing via a stainless-steel
flow control manifold having a pressure gauge, fine adjustment needle valve, rotameter, and
three'way purge/sample valve. The landfill gas analyzer drew a minimum of two sampling tubing
volumes prior to screening and sampling. lf the screened gas contents were below 20 percent
nitrogen or below 5 percent oxygen, then a landfill gas sample could be collected. Where these
field quality controlcriteria were not met, the probe was removed and reinstalled in a new location
before re-screening. All collected samples collected in the field met the pre-screening parameter
requirements listed in methods 25C and 3C.
After field quality control criteria were met, the probe was attached to an evacuated Summa@
canister and sampling train. The sampling train was purged with helium prior to sample collection
as a precaution against cross-canister contamination. The vacuum measurement of the Summa@
canister was recorded. A measured volume of soil gas was drawn into the canister at a rate of
approximately 0.5 liters per minute or less. Flow into the canister was regulated with a needle
valve and the flow rate was monitored using a calibrated rotameter. Atthe completion of sampling,
the vacuum measurement was recorded again.
Sample gas from four discrete sampling locations was composited into a single Summa@ canister
such that 32 discrete sample locations were composited into 8 separate Summa@ canisters.
Before shipping, the final vacuum of the Summa@ canisters were recorded. The samples were
shipped to Air Technology Laboratories, lnc. (ATL) located in City of lndustry, CA under chain of
custody documentation.
Bountiful Sanitary Landfill 2-1 Tier ll Test Report
CHAPTER 3 - ANALYTICAL RESULTS
ANALYTICAL PROCEDURES
HAL measured and recorded the vacuum readings of the Summa@ canisters upon receipt. The
vacuum results are shown in Table 1. No Summa canister was found to lose more than 3 inches
of mercury from the initial laboratory labeled pressure. Based on the elevation difference between
the lab location and sample location, these results assure that no atmospheric intrusion to any of
the received Summa@ canisters occurred during transit. The laboratory pressure measurements
were not available at the time of report production. HAL assumes that there were no issues noted
by the laboratory. lf additional information becomes available that changes this assumption, the
data will be provided under separate cover.

Each Summa@ canister was analyzed by ATL by EPA Methods 25C and 3C for NMOC, nitrogen,
and oxygen contents in triplicate. These methods require the nitrogen content to be less than 20
percent, or alternatively the oxygen content to be less than 5 percent. The quality control results
are shown in Table 2. The average of the triplicate analytical runs are shown. All Summa@
canisters except BSL-2 were found to meet the quality control criteria of <20o/o nitrogen or <5o/o
oxygen. The sample locations comprising BSL-2 often suffered from refusaldue to gas rejection.
However, this sample met the quality control criteria of a nitrogen to oxygen ratio of greater than
3.71 for landfills with 3-year average rainfalls equal to or less than 20 inches. The nearest station
with >90% available precipitation data, BOUNTIFUL 0.8 SE, UT US, had a 3-year (2020-2022)
average rainfall of 18.4 inches.

CHAPTER 2 - TESTING PROTOGOL
GENERAL SAMPLING PROCEDURES NARRATIVE
HAL will utilize a hydraulic, direct-push drilling platform to place landfill gas sampling probes to
depths of 10-20 feet below the existing ground level. The probes will be sealed against ambient
air intrusion into the sampling space.
Each soil gas probe will be purged of two sampling tubing volumes and screened using a portable
landfill gas analyzer. Specifically, gas from each probe location will be screened for methane,
carbon dioxide, oxygen, and nitrogen content. The quality control criteria of EPA Method 25Cl3C
requires oxygen content in gas samples analyzed by the laboratory to be less than 5 percent or
nitrogen to be less than 20 percent. These criteria are used by the laboratory to verify that ambient
air was not drawn into the landfill gas sample and that gas was sampled from an appropriate
location. HAL will apply these same criteria in the field to maximize the potential for laboratory
quality control requirements to be met. lf these field quality control criteria are not met, then the
probe will be removed and reinstalled in a new location where a viable sample can be collected.
After purging and pre-screening the probe, the probe will be attached to an evacuated Summa@
canister and sampling train. The sampling train will be purged with helium prior to sample
collection as a precaution against cross-canister contamination. A measured volume of soil gas
will then be drawn into the canister at a rate of approximately 0.5 liters per minute or less. Flow
into the canister will be regulated with a needle valve and the flow rate will be monitored using a
calibrated rotameter.
Sample gas from four discrete sampling locations will be composited into one Summa@ canister
and submitted as one composite sample to the Laboratory, i.e. 32 discrete sample locations will
be composited into 8 separate Summa@ canisters. The last two sampling locations will be
composited into one Summa@ canister for a total of 34 geoprobe locations composited into 9
Summa@ cannisters.
After samples have been collected the probe will be removed, and the hole will be backfilled with
bentonite chips.
SAMPLING LOCATIONS
Subpart requires two sample locations per hectare (up to 50 total sample locations) and
that sample locations must be located where waste is at least two years old. Based on the
information provided by Bountiful City Engineering, the landfill currently has approximately 42
acres (17 hectares) of area with waste of age greater than two years. Therefore, 34 locations
within this area of the landfill will be sampled for the Tier ll Testing.
According to Bountiful City Engineering, approximately 2.8 hectares in this area is covered with
stockpiled soil. ln the area stockpiled with soil, sample probes will be installed to depths up to 20
feet below landfill surface cover. Sample probes in the remaining sampling area (14.2 hectares)
will be installed to depths up to 10 feet below landfill cover surface. Sample locations will be laid
out in a grid pattern over a current contour map of the landfill and will be marked in the field using
survey lathe and flagging tape. Actual collection points may be adjusted by field representatives
to compensate for poor access, low quality gas, or safety concerns, as necessary.
Bountiful Sanitary Landfill 2-1 Tier ll Testing Protocol
METHOD 25G
EPA Method 25C provides the methods for use in sample collection and analysis of landfill gas.
The landfill gas samples will be collected through a post-run tubing system, as shown in the
Appendix A attachment. A hollow steeldrive rod with a sampling head is advanced to the desired
depth by direct-push methods, the expendable drive point is ejected, and the probe is pulled up
approximately six to twelve inches to create an airtight headspace. ATo-inch polyethylene tube is
inserted through the hollow steel drive rod and connected to the sampling head with an airtight
threaded fitting. Gas can then be sampled from the tubing and pre-screened to ensure minimal
intrusion of ambient air.
The pre-screening will be performed by using a Landtec GEM5000 portable landfill gas analyzer.
The landfill gas analyzer will be connected to the la-inch polyethylene tubing via a stainless-steel
flow control manifold having a pressure gauge, fine adjustment needle valve, rotameter, and
three-way purge/sample valve. The landfill gas analyzer will be on the purge side of the manifold
to draw a minimum of two sampling tubing volumes priorto screening and sampling. The screened
gas contents must be below 20 percent; however, if nitrogen below 20 percent cannot be obtained
a sample may still be collected if oxygen content of less than 5 percent is observed under the
alternative QC requirement of EPA Method 25C.
After purging and pre-screening the probe, the probe will be attached to an evacuated Summa@
canister and sampling train. The sampling train will be purged with helium prior to sample
collection as a precaution against cross-canister contamination. A measured volume of soil gas
will then be drawn into the canister at a rate of approximately 0.5 liters per minute or less. Flow
into the canister will be regulated with a needle valve and the flow rate will be monitored using a
calibrated rotameter.
Summa@ canisters have a volume of six liters at sea level: however, the effective canister volume
at the elevation of the Landfill is reduced to approximately five liters. In addition, the canisters will
be preloaded by the laboratory with one liter of helium, which reduces the effective volume of the
canister to approximately four liters. Helium is added to reduce the potential explosivity hazard of
the methane containing canisters: this eliminates costly hazardous shipment procedures that
would otherwise be required. Nine Summa@ cannisters will be used to composite samples from
34 sample locations. To complete the sample collection at the elevation of the Landfill
(approximately 4,250 feet msl) while adjusting for the available Summa@ canister volume impacts
of altitude, sample gas from 4 discrete sampling locations will be composited into one Summa@
canister and submitted as one composite sample to the Laboratory, i.e. 32 discrete sample
locations will be composited into 8 separate Summa@ canisters. The last two sampling locations
will be composited into one Summa@ canister for a total of 9 landfill gas samples.
The leak-check protocol for the Summa@ canisters is to record the vacuum just prior and
immediately after sampling at each location, and to record a final vacuum just prior to shipping
the Summa@ canisters back to the laboratory. The laboratory will measure the vacuum readings
upon receipt and compare the readings to the pre-shipment readings to ensure the absence of
leaks.
Each Summa@ canister will be analyzed by the laboratory for NMOC in triplicate. The average
result will be the estimate of the average NMOC concentration (as carbon) of the landfill gas. The
NMOC concentration (as carbon) will be divided by six as required in Subpart \ A AlV regulations
to be reported as hexane.
Bountiful Sanitary Landfill 2-2 Tier ll Testing Protocol
EPA METHOD 3C
EPA Method 3C is used to measure the of nitrogen and orygen in the Summa@
canister composite samples. The nitrogen must be less than 20 percent to meet EPA
Method 25C requirements. lf the nitrogen is above 20 percent, EPA Method 25C allows
an alternative requirement of less than five oxygen. The field screening of the landfill gas
by the landfill gas analyzerwill assist in ng that acceptable landfill gas samples are collected

CHAPTER 3 - QUALITY ASSURANCE AND QUALITY
CONTROL
GALIBRATION
The landfill gas analyzer will be calibrated every sampling day for methane and oxygen. The
calibration results will be shown in the test report.
SUMMA CANISTERS
Summa canisters are certified clean before shipment due to their reusable nature. The laboratory
documents cannister cleanliness and conducts regular blank test audits of the process. The
canisters are shipped under approximately -30 inches of mercury (Hg) vacuum, which
corresponds to about -25 to -26.5 inches Hg at the Bountiful Sanitary Landfill altitude.
Upon receipt of the canisters and just prior to sampling, the vacuum in the cannisters will be
checked and recorded to ensure the absence of leaks in transit. The cannister vacuum will be
checked and recorded again after each sample collection, and just prior to shipping back to the
laboratory. The laboratory will check the vacuum upon receipt and compare the readings to the
pre-shipment readings to ensure the absence of leaks in transit.
The Summa canisters will be shipped on the same day of sampling if possible, or the next
morning. lf the Summa canisters are shipped the next morning, the vacuums will be rechecked
and re-recorded prior to shipping.
All data will be recorded on field data sheets with the cannister serial number and on the chain-
of-custody form.
FIELD DATA
The following data will be recorded at each sample location: The boring number or the boring
location (if it was necessary to move the boring to an unnamed position), the landfill gas screening
results, the Summa canister vacuum readings just before and just after sample collection, the
Summa canister serial number, and the sampling start and end times. The ambient air
temperature and general weather conditions will be noted throughout each sampling day. The
collected samples will be handled according to best practice general sampling and chain of
custody procedures and specific laboratory instructions (if any).
LABORATORY ANALYSIS
The Quality Assurance and Quality Control (OA/OC) procedures of EPA Methods 25C and 3C
will be observed by the laboratory for instrument operation, calibration, and calibration verification.
The QfuQC data will be included in the test report.
BACKUP SUMMA CANISTERS
The laboratory will ship one extra Summa canister required for this Tier ll test. lf a cannister is
found to have a leak during the pre-sampling vacuum check, one replacement cannister will be
used.

Post Run Tubing (PRT) Systern allows the
user to collect soil vapor samples quickly
and easily at the desired sampling depth
WITHOUT the time-consuming complications
associated with rod leakage and contami-
nation. O-ring connections enable the PRT
system to deliver a vacuum-tight seal that
prevents sample contamination from UP
hole, and assures that the sample is taken
from the desired depth at the BOTTOM of the
hole. The resulting time savings translates
into a higher productivity rate for you and
your client.

Nors: This method does not include all of the specifications (e.g., equipment and supplies) and
procedures (e.g., sampling and analytical) essential to its performance. Some material is
incorporated by reference from other methods in this part. Therefore, to obtain reliable results,
persons using this method should also have a thorough knowledge of EPA Method 25.
1.0 Scope and Application
LI Analytes.
Analyte AS No.
),lonmethane organic compounds (NMOC)t{o CAS number assigned.
1.2 Applicability. This method is applicable to the sampling and measurement of NMOC as
carbon in landfill gases (LFG).
1.3 Data Quality Objectives. Adherence to the requirements of this method will enhance the
quality of the data obtained from air pollutant sampling methods.
2.0 Summary of Method
2.1 A sample probe that has been perforated at one end is driven or augured to a depth of 0.9 m
(3 ft) below the bottom of the landfill cover. A sample of the landfill gas is extracted with an
evacuated cylinder. The NMOC content of the gas is determined by injecting a portion of the gas
into a gas chromatographic column to separate the NMOC from carbon monoxide (CO), carbon
dioxide (COz), and methane (CH+); the NMOC are oxidized to COz, reduced to CH+, and
measured by a flame ionization detector (FID). In this manner, the variable response of the FID
associated with different types of organics is eliminated.
j.0 Definitions [ReservedJ
4. 0 Interfe re nc e s I Re s erve d]
5.0 Safety
5.1 Since this method is complex, only experienced personnel should perform this test. LFG
contains methane, therefore explosive mixtures may exist on or near the landfill. It is advisable
Method 25C os/30/2023
to take appropriate safety precautions when testing landfills, such as refraining from smoking
and installing explosion-proof equipment.
6.0 Equipment and Supplies
6.1 Sample Probe. Stainless steel, with the bottom third perforated. Teflon probe liners and
sampling lines are also allowed. Non-perforated probes are allowed as long as they are
withdrawn to create a gap equivalent to having the bottom third perforated. The sample probe
must be capped at the bottom and must have a threaded cap with a sampling attachment at the
top. The sample probe must be long enough to go through and extend no less than 0.9 m (3 ft)
below the landfill cover. If the sample probe is to be driven into the landfill, the bottom cap
should be designed to facilitate driving the probe into the landfill.
6.2 Sampling Train.
6.2.1 Rotameter with Flow ControlValve. Capable of measuring a sample flow rate of 100 +10
ml/min. The control valve must be made of stainless steel.
6.2.2 Sampling Valve. Stainless steel.
6.2.3 Pressure Gauge. U-tube mercury manometer, or equivalent, capable of measuring pressure
to within I mm Hg (0.5 in HzO) in the range of 0 to I,100 mm Hg (0 to 590 in HzO).
6.2.4 Sample Tank. Stainless steel or aluminum cylinder, equipped with a stainless steel sample
tank valve.
6.3 Vacuum Pump. Capable of evacuating to an absolute pressure of 10 mm Hg (5.4 in HzO).
6.4 Purging Pump. Portable, explosion proof, and suitable for sampling NMOC.
6.5 Pilot Probe Procedure. The following are needed only if the tester chooses to use the
procedure described in section 8.2.1.
6.5.1 Pilot Probe. Tubing of sufficient strength to withstand being driven into the landfill by a
post driver and an outside diameter of at least 6 mm (0.25 in.) smaller than the sample probe.
The pilot probe shall be capped on both ends and long enough to go through the landfill cover
and extend no less than 0.9 m (3 ft) into the landfill.
6.5.2 Post Driver and Compressor. Capable of driving the pilot probe and the sampling probe
into the landfill. The Kitty Hawk portable post driver has been found to be acceptable.
6.6 Auger Procedure. The following are needed only if the tester chooses to use the procedure
described in section 8.2.2.
6.6.1 Auger. Capable of drilling through the landfill cover and to a depth of no less than 0.9 m (3
ft) into the landfill.
Method 25C
6.6.2Pea Gravel.
6.6.3 Bentonite.
6.7 NMOC Analyzer, Barometer, Thermometer,

7.1 NMOC Analysis. Same as in Method 25, section7.2.
7.2 Calibration. Same as in Method 25, section7.4, except omit section 7.4.3.
8.0 Sample Collection, Preservation, Storage, and Transport
8.1 Sample Tank Evacuation and Leak-Check. Conduct the sample tank evacuation and leak-
check either in the laboratory or the field. Connect the pressure gauge and sampling valve to the
sample tank. Evacuate the sample tank to 10 mm Hg (5.a in HzO) absolute pressure or less.
Close the sampling valve, and allow the tank to sit for 30 minutes. The tank is acceptable if no
change more than *2 mm is noted. Include the results of the leak-check in the test report.
8.2 Sample Probe Installation. The tester may use the procedure in section 8.2.1 or 8.2.2.
8.2.1 Pilot Probe Procedure. Use the post driver to drive the pilot probe at least 0.9 m (3 ft)
below the landfill cover. Altemative procedures to drive the probe into the landfill may be used
subject to the approval of the Administrator's designated representative.
8.2.1.1 Remove the pilot probe and drive the sample probe into the hole left by the pilot probe.
The sample probe shall extend at least 0.9 m (3 ft) below the landfill cover and shall protrude
about 0.3 m (l ft) above the landfill cover. Seal around the sampling probe with bentonite and
cap the sampling probe with the sampling probe cap.
8.2.2 Auger Procedure. Use an auger to drill a hole to at least 0.9 m (3 ft) below the landfill
cover. Place the sample probe in the hole and backfill with pea gravel to a level 0.6 m (2 ft) from
the surface. The sample probe shall protrude at least 0.3 m (1 ft) above the landfill cover. Seal
the remaining area around the probe with bentonite. Allow 24 hours for the landfill gases to
equilibrate inside the augured probe before sampling.
8.2.3 Driven Probes. Closed-point probes may be driven directly into the landfill in a single
step. This method may not require backfilling if the probe is adequately sealed by its insertion.
Unperforated probes that are inserted in this manner and withdrawn at a distance from a
detachable tip to create an open space are also acceptable.
8.3 Sample Train Assembly. Just before assembling the sample train, measure the sample tank
vacuum using the pressure gauge. Record the vacuum, the ambient temperature, and the
Method 25C osl30l2023
barometric pressure at this time. Assemble the sampling probe purging system as shown in
Figure 25C-1.
8.4 Sampling Procedure. Open the sampling valve and use the purge pump and the flow control
valve to evacuate at least two sample probe volumes from the system at a flow rate of 500
ml/min or less. Close the sampling valve and replace the purge pump with the sample tank
apparatus as shown in Figure 25C-2. Open the sampling valve and the sample tank valve and,
using the flow control valve, sample at a flow rate of 500 ml/min or less until either a constant
flow rate can no longer be maintained because of reduced sample tank vacuum or the appropriate
composite volume is attained. Disconnect the sampling tank apparatus and pressurize the sample
cylinder to approximately 1,060 mm Hg (567 in. HzO) absolute pressure with helium, and record
the final pressure. Alternatively, the sample tank may be pressurized in the lab.
8.4.1 The following restrictions apply to compositing samples from different probe sites into a
single cylinder: (1) Individual composite samples per cylinder must be of equal volume; this
must be verified by recording the flow rate, sampling time, vacuum readings, or other
appropriate volume measuring data, (2) individual composite samples must have a minimum
volume of 1 liter unless data is provided showing smaller volumes can be accurately measured,
and (3) composite samples must not be collected using the final cylinder vacuum as it diminishes
to ambient pressure.
8.4.2 Use Method 3C to determine the percent Nz and Oz in each cylinder. The presence of Nz
and Oz indicates either infiltration of ambient air into the landfill gas sample or an inappropriate
testing site has been chosen where anaerobic decomposition has not begun. The landfill gas
sample is acceptable if the concentration ofNz is less than 20 percent. Alternatively, the oxygen
content of each cylinder must be less than 5 percent. Landfills with 3-year average annual
rainfalls equal to or less than 20 inches annual rainfalls samples are acceptable when the N2 to
02 concentration ratio is greater than3.7l.
9.0 Quality Control

Method 25C 0s/3012023
Notp: Maintain a record of performance of each item.
10.1 Initial NMOC Analyzer Performance Test. Same as in Method 25, section 10.1, except omit
the linearity checks for COz standards.
10.2 NMOC Analyzer Daily Calibration.
10.2.1NMOC Response Factors. Same as in Method 25, section 10.2.2.
10.3 Sample Tank Volume. The volume of the gas sampling tanks must be determined.
Determine the tank volumes by weighing them empty and then filled with deionized water;
weigh to the nearest 5 g, and record the results. Alternatively, measure the volume of water used
to fill them to the nearest 5 ml.
I 1.0 Analytical Procedures
I 1.1 The oxidation, reduction, and measurement of NMOC's is similar to Method 25. Before
putting the NMOC analyzer into routine operation, conduct an initial performance test. Start the
analyzer, and perform all the necessary functions in order to put the analyzer into proper working
order. Conduct the performance test according to the procedures established in section 10.1.
Once the performance test has been successfully completed and the NMOC calibration response
factor has been determined, proceed with sample analysis as follows:
I 1.1.1 Daily Operations and Calibration Checks. Before and immediately after the analysis of
each set of samples or on a daily basis (whichever occurs first), conduct a calibration test
according to the procedures established in section 10.2. If the criteria of the daily calibration test
cannot be met, repeat the NMOC analyzer performance test (Section l0.l) before proceeding.
ll.l.2 Operating Conditions. Same as in Method 25, section ll.2.l.
I l.l .3 Analysis of Sample Tank. Purge the sample loop with sample, and then inject the sample.
Under the specified operating conditions, the COz in the sample will elute in approximately 100
seconds. As soon as the detector response returns to baseline following the COz peak, switch the
carrier gas flow to backflush, and raise the column oven temperature to 195 'C (383 oF) as
rapidly as possible. A rate of 30 "C/min (54 'F/min) has been shown to be adequate. Record the
value obtained for any measured NMOC. Return the column oven temperature to 85 oC (185 "F)
in preparation for the next analysis. Analyze each sample in triplicate, and report the average as
Ctr.
I 1.2 Audit Sample Analysis. When the method is used to analyze samples to demonstrate
compliance with a source emission regulation, an audit sample, if available, must be analyzed.
I2.0 Data Analysis and Calculations

Title 40, Protection of Environment,
MBTTToo 3C-DTTnRMINATIoN oF CARBoN DIoxTon, METHANE, NTTROCBN, AND OXYGEN
Fnou Sr.c,rroNaRY SoURCES
1. Applicability and Principle
1.1 Applicability. This method applies to the analysis of carbon dioxide (COz), methane (CH+),
nitrogen (Nz), and oxygen (Oz) in samples from municipal solid waste landfills and other sources
when specified in an applicable subpart.
1.2 Principle. A portion of the sample is injected into a gas chromatograph (GC) and the COz,
CH+, Nz, and Oz concentrations are determined by using a thermal conductivity detector (TCD)
and integrator.
2. Range and Sensitivity
2.1 Range. The range of this method depends upon the concentration of samples. The analytical
range of TCD's is generally between approximately 10 ppmv and the upper percent range.
2.2 Sensitivity. The sensitivity limit for a compound is defined as the minimum detectable
concentration of that compound, or the concentration that produces a signal-to-noise ratio of
three to one. For COz, CHq, Nz, and Oz, the sensitivity limit is in the low ppmv range.
3. Interferences
Since the TCD exhibits universal response and detects all gas components except the carrier,
interferences may occur. Choosing the appropriate GC or shifting the retention times by
changing the column flow rate may help to eliminate resolution interferences.
To assure consistent detector response, helium is used to prepare calibration gases. Frequent
exposure to samples or carrier gas containing oxygen may gradually destroy filaments.
4. Apparatus
4.1 Gas Chromatograph. GC having at least the following components:
4.1 .1 Separation Column. Appropriate column(s) to resolve COz, CH+, Nz, Oz, and other gas
components that may be present in the sample.
4.1.2 Sample Loop. Teflon or stainless steel tubing of the appropriate diameter.
Method 3C 8/2/2017
Norp: Mention of trade names or specific products does not constitute endorsement or
recommendation by the U. S. Environmental Protection Agency.
4.1.3 Conditioning System. To maintain the column and sample loop at constant temperature.
4. 1.4 Thermal Conductivity Detector.
4.2 Recorder. Recorder with linear strip chart. Electronic integrator (optional) is recommended.
4.3 Teflon Tubing. Diameter and length determined by connection requirements of cylinder
regulators and the GC.
4.4 Regulators. To control gas cylinder pressures and flow rates.
4.5 Adsorption Tubes. Applicable traps to remove any Oz from the carrier gas.
5. Reagents
5.1 Calibration and Linearity Gases. Standard cylinder gas mixtures for each compound of
interest with at least three concentration levels spanning the range of suspected sample
concentrations. The calibration gases shall be prepared in helium.
5.2 Carrier Gas. Helium, high-purity.
6. Analysis
6.1 Sample Collection. Use the sample collection procedures described in Methods 3 or 25C to
collect a sample of landfill gas (LFG).
6.2 Preparation of GC. Before putting the GC analyzer into routine operation, optimize the
operational conditions according to the manufacturer's specifications to provide good resolution
and minimum analysis time. Establish the appropriate carrier gas flow and set the detector
sample and reference cell flow rates at exactly the same levels. Adjust the column and detector
temperatures to the recommended levels. Allow sufficient time for temperature stabilization.
This may typically require I hour for each change in temperature.
6.3 Analyzer Linearity Check and Calibration. Perform this test before sample analysis.
6.3.1 Using the gas mixtures in section 5.1, verify the detector linearity over the range of
suspected sample concentrations with at least three concentrations per compound of interest.
This initial check may also serve as the initial instrument calibration.
6.3.2 You may extend the use of the analyzer calibration by performing a single-point calibration
verification. Calibration verifications shall be performed by triplicate injections of a single-point
standard gas. The concentration of the single-point calibration must either be at the midpoint of
Method 3c 812120L7
the calibration curve or at approximately the source emission concentration measured during
operation of the analyzer.
6.3.3 Triplicate injections must agree within 5 percent of their mean, and the average calibration
verification point must agree within l0 percent of the initial calibration response factor. If these
calibration verification criteria are not met, the initial calibration described in section 6.3.1, using
at Ieast three concentrations, must be repeated before analysis of samples can continue.
6.3.4 For each instrument calibration, record the carrier and detector flow rates, detector filament
and block temperatures, attenuation factor, injection time, chart speed, sample loop volume, and
component concentrations.
6.3.5 Plot a linear regression of the standard concentrations versus area values to obtain the
response factor of each compound. Alternatively, response factors of uncorrected component
concentrations (wet basis) may be generated using instrumental integration.
Nots: Peak height may be used instead of peak area throughout this method.
6.4 Sample Analysis. Purge the sample loop with sample, and allow to come to atmospheric
pressure before each injection. Analyze each sample in duplicate, and calculate the average
sample area (A). The results are acceptable when the peak areas for two consecutive injections
agree within 5 percent of their average. If they do not agree, run additional samples until
consistent area data are obtained. Determine the tank sample concentrations according to section
7.2.
7. Calculations
Carry out calculations retaining at least one extra decimal figure beyond that of the acquired
data. Round off results only after the final calculation.
7.1 Nomenclature.
B*: Moisture content in the sample, fraction.
Cuz : Measured Nz concentration (by Method 3C), fraction.
CN2co'.: Measured Nz concentration corrected only for dilution, fraction.
Ct: Calculated NMOC concentration, ppmv C equivalent.
Ctm : Measured NMOC concentration, ppmv C equivalent.
Pu: Barometric pressure, mm Hg.
Pt: Gas sample tank pressure after sampling, but before pressurizing, mm Hg absolute.
Ptr: Final gas sample tank pressure after pressurizing, mm Hg absolute.
Pti: Gas sample tank pressure after evacuation, mm Hg absolute.
Method 3C 812120L7
P*: Vapor pressure of HzO (from Table 25C-l), mm Hg.
r : Total number of analyzer injections of sample tank during analysis (where j : injection
number, 1...r).
R: Mean calibration response factor for specific sample component, area./ppm.
Tt = Sample tank temperature at completion of sampling, oK.
Tr : Sample tank temperature before sampling, oK.
Ttr: Sample tank temperature after pressurizing, oK.
7.2 Concentration of Sample Components. Calculate C for each compound using Equations 3C-1
and3C-2. Use the temperature and barometric pressure at the sampling site to calculate Bw. If
the sample was diluted with helium using the procedures in Method 25C, use Equation 3C-3 to
calculate the concentration.

DIVISION OF AIR QUALTN:
SUBJECT:2023-2027 REVISED NMOC EMISSION RATE RPT - 5 YEAR ESTIMATE
BOUNTIFUL SANITARY LANDFILL
Dear Sir or Madam:
According to the Utah Administrative Code and Bountiful City's Title V Operating Permit I have
completed and enclosed a revised five-year estimate of the Non-Methane Organic Compounds
(NMOC) Emission Rate Report for 2023-2Q27 for the BountifulSanitary Landfill. A previous five-
year estimate was submitted to the Division of Air Quality on March 26,20L9. Each previous
report has shown the NMOC Emission Rate to be less than 34 Mg/year. Thus, according to the
city's Title V Operating Permit the city is eligible to submit an estimate of the NMOC emission rate
for a five year period in lieu of annual NMOC reports. The report again shows the NMOC emission
rate to be much less than 50 Mg/year, and much less than the pending threshold of 34 Mg/yr.
The report is completed on a form provided by the Utah Division of Air Quality. The data,
calculations, spreadsheets, and computer model outputs which were used to calculate the
required information are attached. The landfill NMOC emissions were calculated using the Landfill
Gas Emissions Model "LandcEM". We used arid climate defaults with user-specified NMOC
concentration.
The NMOC concentration data was determined for the Bountiful Sanitary Landfill from site specific
landfill gas collection and testing (Tier ll) in compliance with EPA Method 25C and EPA Method 3C.
This sampling and testing was completed in December 2023. A summary of the Tier ll testing
results is attached.

LandGEM is based on a firstorder 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:/Aamw.epa.gov/ttnahr/O1/landfi ll/landfl pg.html.
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 at a faster rate. Defaults for estimating emissions for this 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.

CHAPTER 1 . INTRODUCTION
INTRODUCTION
Bountiful City selected Hansen, Allen, & Luce, lnc. (HAL) to conduct the Tier ll landfill gas testing
services for the Bountiful Sanitary Landfill. Under the New Source Performance Standards
(NSPS) federal regulations (40 CFR Part 60, Subpart the Bountiful Sanitary Landfill is
currently required to test and estimate the non-methane organic compound (NMOC) rate every
five years. The results of this Tier ll landfill gas test will be used by Bountiful City Engineering to
calculate the annual NMOC emissions rate to determine if the threshold emission rate for installing
a landfill gas collection and control system is triggered.
HAL completed the Tier ll landfill gas testing on December 1,2023 and received preliminary
analytical results on December 22, 2023. Chapter 2 contains descriptions of the field activities
and Chapter 3 contains analytical and quality control results for this testing event.
LANDFILL DESCRIPTION
The Bountiful Sanitary Landfill is a Class I landfill operating under a Title V Operating Permit
(#1100113004 dated February 27,2019) located at 1300 West Page Lane in West Bountiful,
Utah. The Landfill has been in operation for 37 years, having first accepted waste in 1987 and
becoming permitted in 2000. The historic and active landfill area is about 100 acres. About 40
acres ('t6 hectares) of the landfill containswaste of age greaterthan two years. About 59 acres
of the historic landfill contains primarily ash from historic open burning of waste, which is mostly
located in the South Cell. This material has been tested and shown to produce no methane, so
NMOC rate testing is not appropriate in this portion of the landfill (40 CFR 60.754(aX3)). The
Bountiful Sanitary Landfill and the portions which are not methane-producing are shown in Figure
1.
Bountiful Sanitary Landfill 1-1 Tier ll Test Report
CHAPTER 2 - FIELD ACTIVITIES
SAMPLING LOCATIONS
32 locations within the area of the landfill containing waste for 2 or more years were sampled for
the Tier ll Testing. Sample locations were laid out in a grid pattern over a current contour map of
the landfill. Actual collection points were occasionally adjusted by field representatives to
compensate for poor access, low quality gas, or safety concerns, as necessary. These locations
are shown in Figure 1.
SAMPLING PROCEDURES
Samples were collected according to EPA methods 25C and 3C. HAL utilized a hydraulic, direct-
push drilling platform to place landfill gas sampling probes to depths of 5-15 feet below the existing
ground level. The probes were sealed against ambient air intrusion into the sampling space. The
landfill gas samples were collected through a post-run tubing system.
A hollow steel drive rod with a sampling head was advanced to the desired depth by directpush
methods, the expendable drive point was ejected, and the probe was retracted approximately six
to twelve inches to create an airtight headspace . A/+-inch polyethylene tube was inserted through
the hollow steel drive rod and connected to the sampling head with an airtight threaded fitting.
The pre-screening was performed by using a Landtec GEM5000 portable landfill gas analyzer.
The landfill gas analyzer was be connected to the le-inch polyethylene tubing via a stainless-steel
flow control manifold having a pressure gauge, fine adjustment needle valve, rotameter, and
three.way purge/sample valve. The landfill gas analyzer drew a minimum of two sampling tubing
volumes prior to screening and sampling. !f the screened gas contents were below 20 percent
nitrogen or below 5 percent oxygen, then a landfill gas sample could be collected. Where these
field quality controlcriteria were not met, the probe was removed and reinstalled in a new location
before re-screening. All collected samples collected in the field met the pre-screening parameter
requirements listed in methods 25C and 3C.
After field quality control criteria were met, the probe was attached to an evacuated Summa@
canister and sampling train. The sampling train was purged with helium prior to sample collection
as a precaution against cross-canister contamination. The vacuum measurement of the Summa@
canister was recorded. A measured volume of soil gas was drawn into the canister at a rate of
approximately 0.5 liters per minute or less. Flow into the canister was regulated with a needle
valve and the flow rate was monitored using a calibrated rotameter. At the completion of sampling,
the vacuum measurement was recorded again.
Sample gas from four discrete sampling locations was composited into a single Summa@ canister
such that 32 discrete sample locations were composited into 8 separate Summa@ canisters.
Before shipping, the final vacuum of the Summa@ canisters were recorded. The samples were
shipped to Air Technology Laboratories, lnc. (ATL) located in City of lndustry, CA under chain of
custody documentation.
Bountiful Sanitary Landfi ll 2-1 Tier ll Test Report
CHAPTER 3 - ANALYTICAL RESULTS
ANALYTICAL PROGEDURES
HAL measured and recorded the vacuum readings of the Summa@ canisters upon receipt. The
vacuum results are shown in Table 1. No Summa canister was found to lose more than 3 inches
of mercury from the initial laboratory labeled pressure. Based on the elevation difference between
the lab location and sample location, these results assure that no atmospheric intrusion to any of
the received Summa@ canisters occurred during transit. The laboratory pressure measurements
were not available at the time of report production. HAL assumes that there were no issues noted
by the laboratory. lf additional information becomes available that changes this assumption, the
data will be provided under separate cover.

V Measurements in lnches of Merc
Each Summa@ canister was analyzed by ATL by EPA Methods 25C and 3C for NMOC, nitrogen,
and oxygen contents in triplicate. These methods require the nitrogen content to be less than 20
percent, or alternatively the oxygen content to be less than 5 percent. The quality control results
are shown in Table 2. The average of the triplicate analytical runs are shown. All Summa@
canisters except BSL-2 were found to meet the quali$ control criteria of <20%o nitrogen or <5o/o
oxygen. The sample locations comprising BSL-2 often suffered from refusaldue to gas rejection.
However, this sample met the quality control criteria of a nitrogen to oxygen ratio of greater than
3.71 for landfills with 3-year average rainfalls equal to or less than 20 inches. The nearest station
with >90% available precipitation data, BOUNTIFUL 0.8 SE, UT US, had a 3-year (2020-2022)
average rainfall of 18.4 inches.

CHAPTER 2 - TESTING PROTOCOL
GENERAL SAMPLING PROCEDURES NARRATIVE
HAL will utilize a hydraulic, direct-push drilling platform to place landfill gas sampling probes to
depths of 10-20 feet below the existing ground level. The probes will be sealed against ambient
air intrusion into the sampling space.
Each soil gas probe will be purged of two sampling tubing volumes and screened using a portable
landfill gas analyzer. Specifically, gas from each probe location will be screened for methane,
carbon dioxide, oxygen, and nitrogen content. The quality controlcriteria of EPA Method 25Cl3C
requires oxygen content in gas samples analyzed by the laboratory to be less than 5 percent or
nitrogen to be less than 20 percent. These criteria are used by the laboratory to verify that ambient
air was not drawn into the landfill gas sample and that gas was sampled from an appropriate
location. HAL will apply these same criteria in the field to maximize the potential for laboratory
quality control requirements to be met. lf these field quality control criteria are not met, then the
probe will be removed and reinstalled in a new location where a viable sample can be collected.
After purging and pre-screening the probe, the probe will be attached to an evacuated Summa@
canister and sampling train. The sampling train will be purged with helium prior to sample
collection as a precaution against cross-canister contamination. A measured volume of soil gas
will then be drawn into the canister at a rate of approximately 0.5 liters per minute or less. Flow
into the canister will be regulated with a needle valve and the flow rate will be monitored using a
calibrated rotameter.
Sample gas from four discrete sampling locations will be composited into one Summa@ canister
and submitted as one composite sample to the Laboratory, i.e.32 discrete sample locations will
be composited into 8 separate Summa@ canisters. The last two sampling locations will be
composited into one Summa@ canister for a total of 34 geoprobe locations composited into 9
Summa@ cannisters.
After samples have been collected the probe will be removed, and the hole will be backfilled with
bentonite chips.
SAMPLING LOCATIONS
Subpart V1A AlV requires two sample locations per hectare (up to 50 total sample locations) and
that sample locations must be located where waste is at least two years old. Based on the
information provided by Bountiful City Engineering, the landfill currently has approximately 42
acres (17 hectares) of area with waste of age greater than two years. Therefore, 34 locations
within this area of the landfill will be sampled for the Tier ll Testing.
According to Bountiful City Engineering, approximately 2.8 hectares in this area is covered with
stockpiled soil. ln the area stockpiled with soil, sample probes will be installed to depths up to 20
feet below landfill surface cover. Sample probes in the remaining sampling area (14.2 hectares)
will be installed to depths up to 10 feet below landfill cover surface. Sample locations will be laid
out in a grid pattern over a current contour map of the landfill and will be marked in the field using
survey lathe and flagging tape. Actual collection points may be adjusted by field representatives
to compensate for poor access, low quality gas, or safety concerns, as necessary.
Bountiful Sanitary Landfi ll 2-1 Tier ll Testing Protocol
METHOD 25C
EPA Method 25C provides the methods for use in sample collection and analysis of landfill gas.
The landfill gas samples will be collected through a post-run tubing system, as shown in the
Appendix A attachment. A hollow steel drive rod with a sampling head is advanced to the desired
depth by direct-push methods, the expendable drive point is ejected, and the probe is pulled up
approximately six to twelve inches to create an airtight headspace . Ala-inch polyethylene tube is
inserted through the hollow steel drive rod and connected to the sampling head with an airtight
threaded fitting. Gas can then be sampled from the tubing and pre-screened to ensure minimal
intrusion of ambient air.
The pre-screening will be performed by using a Landtec GEM5000 portable landfill gas analyzer.
The landfill gas analyzer will be connected to the Yo-inch polyethylene tubing via a stainless-steel
flow control manifold having a pressure gauge, fine adjustment needle valve, rotameter, and
three-way purge/sample valve. The landfill gas analyzer will be on the purge side of the manifold
to draw a minimum of two sampling tubing volumes priorto screening and sampling. The screened
gas contents must be below 20 percent; however, if nitrogen below 20 percent cannot be obtained
a sample may still be collected if oxygen content of less than 5 percent is observed under the
alternative QC requirement of EPA Method 25C.
After purging and pre-screening the probe, the probe will be attached to an evacuated Summa@
canister and sampling train. The sampling train will be purged with helium prior to sample
collection as a precaution against cross-canister contamination. A measured volume of soil gas
will then be drawn into the canister at a rate of approximately 0.5 liters per minute or less. Flow
into the canister will be regulated with a needle valve and the flow rate will be monitored using a
calibrated rotameter.
Summa@ canisters have a volume of six liters at sea level: however, the effective canister volume
at the elevation of the Landfill is reduced to approximately five liters. ln addition, the canisters will
be preloaded by the laboratory with one liter of helium, which reduces the effective volume of the
canister to approximately four liters. Helium is added to reduce the potential explosivity hazard of
the methane containing canisters: this eliminates costly hazardous shipment procedures that
would otherurise be required. Nine Summa@ cannisters will be used to composite samples from
34 sample locations. To complete the sample collection at the elevation of the Landfill
(approximately 4,250 feet msl) while adjusting for the available Summa@ canister volume impacts
of altitude, sample gas from 4 discrete sampling locations will be composited into one Summa@
canister and submitted as one composite sample to the Laboratory, i.e. 32 discrete sample
locations will be composited into 8 separate Summa@ canisters. The last two sampling locations
will be composited into one Summa@ canister for a total of 9 landfill gas samples.
The leak-check protocol for the Summa@ canisters is to record the vacuum just prior and
immediately after sampling at each location, and to record a final vacuum just prior to shipping
the Summa@ canisters back to the laboratory. The laboratory will measure the vacuum readings
upon receipt and compare the readings to the pre-shipment readings to ensure the absence of
leaks.
Each Summa@ canister will be analyzed by the laboratory for NMOC in triplicate. The average
result will be the estimate of the average NMOC concentration (as carbon) of the landfill gas. The
NMOC concentration (as carbon) will be divided by six as required in Subpart regulations
to be reported as hexane.
Bountiful Sanitary Landfi ll 2-2 Tier ll Testing Protocol
EPA METHOD 3C
EPA Method 3C is used to measure the of nitrogen and orygen in the Summa@
canister composite samples. The content must be less than 20 percent to meet EPA
Method 25C requirements. lf the nitrogen is above 20 percent, EPA Method 25C allows
an altemative requirement of less than
by the landfill gas analyzer will assist in
orygen. The field screening of the landfill gas

CHAPTER 3 - QUALITY ASSURANCE AND QUALITY
CONTROL
CAL!BRAT!ON
The landfill gas analyzer will be calibrated every sampling day for methane and oxygen. The
calibration results will be shown in the test report.
SUMMA CANISTERS
Summa canisters are certified clean before shipment due to their reusable nature. The laboratory
documents cannister cleanliness and conducts regular blank test audits of the process. The
canisters are shipped under approximately -30 inches of mercury (Hg) vacuum, which
corresponds to about -25to -26.5 inches Hg at the Bountiful Sanitary Landfill altitude.
Upon receipt of the canisters and just prior to sampling, the vacuum in the cannisters will be
checked and recorded to ensure the absence of leaks in transit. The cannister vacuum will be
checked and recorded again after each sample collection, and just prior to shipping back to the
laboratory. The laboratory will check the vacuum upon receipt and compare the readings to the
pre-shipment readings to ensure the absence of leaks in transit.
The Summa canisters will be shipped on the same day of sampling if possible, or the next
morning. lf the Summa canisters are shipped the next morning, the vacuums will be rechecked
and re.recorded prior to shipping.
All data will be recorded on field data sheets with the cannister serial number and on the chain-
of-custody form.
FIELD DATA
The following data will be recorded at each sample location: The boring number or the boring
location (if it was necessary to move the boring to an unnamed position), the landfill gas screening
results, the Summa canister vacuum readings just before and just after sample collection, the
Summa canister serial number, and the sampling start and end times. The ambient air
temperature and general weather conditions will be noted throughout each sampling day. The
collected samples will be handled according to best practice general sampling and chain of
custody procedures and specific laboratory instructions (if any).
LABORATORY ANALYSIS
The Quality Assurance and Quality Control (OA/OC) procedures of EPA Methods 25C and 3C
will be observed by the laboratory for instrument operation, calibration, and calibration verification.
The QA/QC data will be included in the test report.
BACKUP SUMMA CANISTERS
The laboratory will ship one extra Summa canister required for this Tier ll test. lf a cannister is
found to have a leak during the pre-sampling vacuum check, one replacement cannister will be
used.

Bountiful Sanitary Landfill F-2 Tier ll Testing Protocol
Direct push machines were inrtrally des gned specifrcally for soil gas sampling. Our flrst set of tools were manufactured to extract
vapor samples. Before Geoprobet'tools and equipment w'ere available, most soil gas sampling was done by manualiy advancing
NPT pipe into the ground surface usrng a slam bar, often followed by us ng a bumper-style lack to remove the NPT pipe
We then developed a simpie, quick, cost-effective methoc for conducting soil gas sampling - Post Run fubing (PRT) Systems and
SoilVapor lmplants. The PRT method decreased labor costs, time requ rements, and decontamination fluids generated for sample
collection.

Notp: This method does not include all of the specifications (e.g., equipment and supplies) and
procedures (e.g., sampling and analytical) essential to its performance. Some material is
incorporated by reference from other methods in this part. Therefore, to obtain reliable results,
persons using this method should also have a thorough knowledge of EPA Method 25.
1.0 Scope and Application
l.l Analytes.
A,nalyte CAS No.
\onmethane orsanic comDounds INMOC)\o CAS number assigned.
1.2 Applicability. This method is applicable to the sampling and measurement of NMOC as
carbon in landfill gases (LFG).
1.3 Data Quality Objectives. Adherence to the requirements of this method will enhance the
quality of the data obtained from air pollutant sampling methods.
2.0 Summary of Method
2.1 A sample probe that has been perforated at one end is driven or augured to a depth of 0.9 m
(3 ft) below the bottom of the landfill cover. A sample of the landfill gas is extracted with an
evacuated cylinder. The NMOC content of the gas is determined by injecting a portion of the gas
into a gas chromatographic column to separate the NMOC from carbon monoxide (CO), carbon
dioxide (COz), and methane (CH+); the NMOC are oxidized to COz, reduced to CH+, and
measured by a flame ionization detector (FID). In this manner, the variable response of the FID
associated with different types of organics is eliminated.
3.0 Definitions [ReservedJ
4. 0 Interferenc es I ReservedJ
5.0 Safety
5.1 Since this method is complex, only experienced personnel should perform this test. LFG
contains methane, therefore explosive mixtures may exist on or near the landfill. It is advisable
Method 25C osl30l2023
to take appropriate safety precautions when testing landfills, such as refraining from smoking
and installing explosion-proof equipment.
6.0 Equipment and Supplies
6.1 Sample Probe. Stainless steel, with the bottom third perforated. Teflon probe liners and
sampling lines are also allowed. Non-perforated probes are allowed as long as they are
withdrawn to create a gap equivalent to having the bottom third perforated. The sample probe
must be capped at the bottom and must have a threaded cap with a sampling affachment at the
top. The sample probe must be long enough to go through and extend no less than 0.9 m (3 ft)
below the landfill cover. If the sample probe is to be driven into the landfill, the bottom cap
should be designed to facilitate driving the probe into the landfill.
6.2 Sampling Train.
6.2.1 Rotameter with Flow Control Valve. Capable of measuring a sample flow rate of 100 +10
ml/min. The control valve must be made of stainless steel.
6.2.2 Sampling Valve. Stainless steel.
6.2.3 Pressure Gauge. U-tube mercury manometer, or equivalent, capable of measuring pressure
to within 1 mm Hg (0.5 in HzO) in the range of 0 to 1,100 mm Hg (0 to 590 in HzO).
6.2.4 Sample Tank. Stainless steel or aluminum cylinder, equipped with a stainless steel sample
tank valve.
6.3 Vacuum Pump. Capable of evacuating to an absolute pressure of 10 mm Hg (5.a in HzO).
6.4 Purging Pump. Portable, explosion proof, and suitable for sampling NMOC.
6.5 Pilot Probe Procedure. The following are needed only if the tester chooses to use the
procedure described in section 8.2.1.
6.5.1 Pilot Probe. Tubing of sufficient strength to withstand being driven into the landfill by a
post driver and an outside diameter of at least 6 mm (0.25 in.) smaller than the sample probe.
The pilot probe shall be capped on both ends and long enough to go through the landfill cover
and extend no less than 0.9 m (3 ft) into the landfill.
6.5.2 Post Driver and Compressor. Capable of driving the pilot probe and the sampling probe
into the landfill. The Kitty Hawk portable post driver has been found to be acceptable.
6.6 Auger Procedure. The following are needed only if the tester chooses to use the procedure
described in section 8.2.2.
6.6.1 Auger. Capable of drilling through the landfill cover and to a depth of no less than 0.9 m (3
ft) into the landfill.
Method 25C
6.6.2Pea Gravel.
6.6.3 Bentonite.
6.7 NMOC Analyzer, Barometer, Thermometer, and
6.33, and 6.2.10, respectively, of Method 25.
7.0 Reagents and Standards
0s/3012023
Syringes. Same as in sections 6.3.1,6.3.2,
7.1 NMOC Analysis. Same as in Method 25, section7.2.
7.2 Calibration. Same as in Method 25, section 7.4, except omit section 7.4.3.
8.0 Sample Collection, Preservation, Storage, and Transport
8.1 Sample Tank Evacuation and Leak-Check. Conduct the sample tank evacuation and leak-
check either in the laboratory or the field. Connect the pressure gauge and sampling valve to the
sample tank. Evacuate the sample tank to l0 mm Hg (5.a in HzO) absolute pressure or less.
Close the sampling valve, and allow the tank to sit for 30 minutes. The tank is acceptable if no
change more than t2 mm is noted. Include the results of the leak-check in the test report.
8.2 Sample Probe Installation. The tester may use the procedure in section 8.2.1 or 8.2.2.
8.2.1 Pilot Probe Procedure. Use the post driver to drive the pilot probe at least 0.9 m (3 ft)
below the landfill cover. Alternative procedures to drive the probe into the landfill may be used
subject to the approval of the Administrator's designated representative.
8.2.1 .l Remove the pilot probe and drive the sample probe into the hole left by the pilot probe.
The sample probe shall extend at least 0.9 m (3 ft) below the landfill cover and shall protrude
about 0.3 m (l ft) above the landfill cover. Seal around the sampling probe with bentonite and
cap the sampling probe with the sampling probe cap.
8.2.2 Auger Procedure. Use an auger to drill a hole to at least 0.9 m (3 ft) below the landfill
cover. Place the sample probe in the hole and backfill with pea gravel to a level 0.6 m (2 ft) from
the surface. The sample probe shall protrude at least 0.3 m (l ft) above the landfill cover. Seal
the remaining area around the probe with bentonite. Allow 24 hours for the landfill gases to
equilibrate inside the augured probe before sampling.
8.2.3 Driven Probes. Closed-point probes may be driven directly into the landfill in a single
step. This method may not require backfilling if the probe is adequately sealed by its insertion.
Unperforated probes that are inserted in this manner and withdrawn at a distance from a
detachable tip to create an open space are also acceptable.
8.3 Sample Train Assembly. Just before assembling the sample train, measure the sample tank
vacuum using the pressure gauge. Record the vacuum, the ambient temperature, and the
Method 25C osl30l2023
barometric pressure at this time. Assemble the sampling probe purging system as shown in
Figure 25C-1.
8.4 Sampling Procedure. Open the sampling valve and use the purge pump and the flow control
valve to evacuate at least two sample probe volumes from the system at a flow rate of 500
ml/min or less. Close the sampling valve and replace the purge pump with the sample tank
apparatus as shown in Figure 25C-2. Open the sampling valve and the sample tank valve and,
using the flow control valve, sample at a flow rate of 500 ml/min or less until either a constant
flow rate can no longer be maintained because of reduced sample tank vacuum or the appropriate
composite volume is attained. Disconnect the sampling tank apparatus and pressurize the sample
cylinder to approximately 1,060 mm Hg (567 in. HzO) absolute pressure with helium, and record
the final pressure. Alternatively, the sample tank may be pressurized in the lab.
8.4.1 The following restrictions apply to compositing samples from different probe sites into a
single cylinder: (l) Individual composite samples per cylinder must be of equal volume; this
must be verified by recording the flow rate, sampling time, vacuum readings, or other
appropriate volume measuring data, (2) individual composite samples must have a minimum
volume of I liter unless data is provided showing smaller volumes can be accurately measured,
and (3) composite samples must not be collected using the final cylinder vacuum as it diminishes
to ambient pressure.
8.4.2 Use Method 3C to determine the percent Nz and Oz in each cylinder. The presence of Nz
and Oz indicates either infiltration of ambient air into the landfill gas sample or an inappropriate
testing site has been chosen where anaerobic decomposition has not begun. The landfill gas
sample is acceptable if the concentration of Nz is less than 20 percent. Alternatively, the oxygen
content of each cylinder must be less than 5 percent. Landfills with 3-year average annual
rainfalls equal to or less than20 inches annual rainfalls samples are acceptable when the N2 to
02 concentration ratio is greater than3.7l.
9.0 Quality Control
9.1 Miscellaneous Quality Control Measures.

t.4.2 If the 3-year average annual rainfall is greater than20
inches, verify that landfill gas sample contains less than 20
percent Nz or 5 percent Oz. Landfills with 3- year average
annual rainfalls equal to or less than 20 inches annual
rainfalls samples are acceptable when the Nz to Oz
concentration ratio is greater than 3.71.

I 0.0 Calibration and Standordizotion
Method 25C 0sl30l2023
Norp: Maintain a record of performance of each item.
10.1 Initial NMOC Analyzer Performance Test. Same as in Method 25, section 10.1, except omit
the linearity checks for COz standards.
10.2 NMOC Analyzer Daily Calibration.
10.2.1NMOC Response Factors. Same as in Method 25, section 10.2.2.
10.3 Sample Tank Volume. The volume of the gas sampling tanks must be determined.
Determine the tank volumes by weighing them empty and then filled with deionized water;
weigh to the nearest 5 g, and record the results. Alternatively, measure the volume of water used
to fill them to the nearest 5 ml.
I 1.0 Anolytical Procedures
1 l.l The oxidation, reduction, and measurement of NMOC's is similar to Method 25. Before
putting the NMOC analyzer into routine operation, conduct an initial performance test. Start the
analyzer, and perform all the necessary functions in order to put the analyzer into proper working
order. Conduct the performance test according to the procedures established in section 10.1.
Once the performance test has been successfully completed and the NMOC calibration response
factor has been determined, proceed with sample analysis as follows:
I I .l .l Daily Operations and Calibration Checks. Before and immediately after the analysis of
each set of samples or on a daily basis (whichever occurs first), conduct a calibration test
according to the procedures established in section 10.2. If the criteria of the daily calibration test
cannot be met, repeat the NMOC analyzer performance test (Section l0.l ) before proceeding.
ll.l.2 Operating Conditions. Same as in Method 25, section ll.2.l.
I I .1.3 Analysis of Sample Tank. Purge the sample loop with sample, and then inject the sample.
Under the specified operating conditions, the COz in the sample will elute in approximately 100
seconds. As soon as the detector response returns to baseline following the COz peak, switch the
carrier gas flow to backflush, and raise the column oven temperature to 195 "C (383 oF) as
rapidly as possible. A rate of 30 'Clmin (54 'F/min) has been shown to be adequate. Record the
value obtained for any measured NMOC. Retum the column oven temperature to 85 oC (185 'F)
in preparation for the next analysis. Analyze each sample in triplicate, and report the average as
Ct..
I 1.2 Audit Sample Analysis. When the method is used to analyze samples to demonstrate
compliance with a source emission regulation, an audit sample, if available, must be analyzed.
I2.0 Data Analysis and Calculations
Norp: All equations are written using absolute pressure; absolute pressures are determined by
adding the measured barometric pressure to the measured gauge or manometer pressure.

1. Applicability and Principle
l.l Applicability. This method applies to the analysis of carbon dioxide (COz), methane (CH+),
nitrogen (Nz), and oxygen (Oz) in samples from municipal solid waste landfills and other sources
when specified in an applicable subpart.
1.2 Principle. A portion of the sample is injected into a gas chromatograph (GC) and the COz,
CH+, Nz, and Oz concentrations are determined by using a thermal conductivity detector (TCD)
and integrator.
2. Range and Sensitivity
2.1 Range. The range of this method depends upon the concentration of samples. The analytical
range of TCD's is generally between approximately 10 ppmv and the upper percent range.
2.2 Sensitivity. The sensitivity limit for a compound is defined as the minimum detectable
concentration of that compound, or the concentration that produces a signal-to-noise ratio of
three to one. For COz, CH+, N2, and Oz, the sensitivity limit is in the low ppmv range.
3. Interferences
Since the TCD exhibits universal response and detects all gas components except the carrier,
interferences may occur. Choosing the appropriate GC or shifting the retention times by
changing the column flow rate may help to eliminate resolution interferences.
To assure consistent detector response, helium is used to prepare calibration gases. Frequent
exposure to samples or carrier gas containing oxygen may gradually destroy filaments.
4. Apparatus
4.1 Gas Chromatograph. GC having at least the following components:
4.1.1 Separation Column. Appropriate column(s) to resolve COz, CH+, Nz, Oz, and other gas
components that may be present in the sample.
4.1.2 Sample Loop. Teflon or stainless steel tubing of the appropriate diameter.
Method 3C 812120L7
Nore: Mention of trade names or specific products does not constitute endorsement or
recommendation by the U. S. Environmental Protection Agency.
4.1.3 Conditioning System. To maintain the column and sample loop at constant temperature.
4. 1.4 Thermal Conductivity Detector.
4.2 Recorder. Recorder with linear strip chart. Electronic integrator (optional) is recommended.
4.3 Teflon Tubing. Diameter and length determined by connection requirements of cylinder
regulators and the GC.
4.4 Regulators. To control gas cylinder pressures and flow rates.
4.5 Adsorption Tubes. Applicable traps to remove any Oz from the carrier gas.
5. Reagents
5.1 Calibration and Linearity Gases. Standard cylinder gas mixtures for each compound of
interest with at least three concentration levels spanning the range of suspected sample
concentrations. The calibration gases shall be prepared in helium.
5.2 Carrier Gas. Helium, high-purity.
6. Analysis
6.1 Sample Collection. Use the sample collection procedures described in Methods 3 or 25C to
collect a sample of landfill gas (LFG).
6.2Preparation of GC. Before putting the GC analyzer into routine operation, optimize the
operational conditions according to the manufacfurer's specifications to provide good resolution
and minimum analysis time. Establish the appropriate carrier gas flow and set the detector
sample and reference cell flow rates at exactly the same levels. Adjust the column and detector
temperatures to the recommended levels. Allow sufficient time for temperature stabilization.
This may typically require I hour for each change in temperature.
6.3 Analyzer Linearity Check and Calibration. Perform this test before sample analysis.
6.3.1 Using the gas mixtures in section 5.1, verify the detector linearity over the range of
suspected sample concentrations with at least three concentrations per compound of interest.
This initial check may also serye as the initial instrument calibration.
6.3.2You may extend the use of the analyzer calibration by performing a single-point calibration
verification. Calibration verifications shall be performed by triplicate injections of a single-point
standard gas. The concentration of the single-point calibration must either be at the midpoint of
Method 3C 81212017
the calibration curve or at approximately the source emission concentration measured during
operation of the analyzer.
6.3.3 Triplicate injections must agree within 5 percent of their mean, and the average calibration
verification point must agree within I 0 percent of the initial calibration response factor. If these
calibration verification criteria are not met, the initial calibration described in section 6.3.1, using
at least three concentrations, must be repeated before analysis of samples can continue.
6.3.4 For each instrument calibration, record the carrier and detector flow rates, detector filament
and block temperatures, attenuation factor, injection time, chart speed, sample loop volume, and
component concentrations.
6.3.5 Plot a linear regression of the standard concentrations versus area values to obtain the
response factor of each compound. Alternatively, response factors of uncorrected component
concentrations (wet basis) may be generated using instrumental integration.
Nots: Peak height may be used instead of peak area throughout this method.
6.4 Sample Analysis. Purge the sample loop with sample, and allow to come to atmospheric
pressure before each injection. Analyze each sample in duplicate, and calculate the average
sample area (A). The results are acceptable when the peak areas for two consecutive injections
agree within 5 percent of their average. If they do not agree, run additional samples until
consistent area data are obtained. Determine the tank sample concentrations according to section
7.2.
7. Calculations
Carry out calculations retaining at least one extra decimal figure beyond that of the acquired
data. Round off results only after the final calculation.
