Subject: Review of Tier 2 NMOC test report and annual NMOC Emissions
Estimate report dated November 16, 2023

On November 17, 2023, the Utah Division of Air Quality (DAQ) received a tier 2 test report and NMOC
emissions estimate for landfill gas emissions testing of the Logan City Landfill located in Logan City,
Cache County, Utah. Testing was performed on September 14-15 and September 22, 2023, to determine
compliance with Title V operating permit condition II.B.2.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 25 sites 10-20 feet below the landfill cover using subsurface sampling probes, which were
composited into nine summa canisters. The sites were in landfill areas that have contained waste for
longer than two years. Logan City Landfill is an active class I MSW landfill. The landfill emissions
testing report appears to use the specified formulas and testing methods as outlined in the tier 2 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 5.84 mega-grams for the
calendar year 2023. Calculations used EPA LandGEM version 3.02 and the test results for NMOC
concentration of 99.3 ppmv as hexane and an estimated waste acceptance growth rate of 4 percent
annually for the next five years (2023-2027), was input to the LandGEM model and used to estimate
NMOC emissions for the next five years.

DEVIATIONS: None noted.

CONCLUSION: As reported 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 the annual
growth rate of 4 percent, as assumed in this report. If waste acceptance
rates exceed a 4 percent annual increase for any of the next five years,
Logan City Landfill personnel will either revise this five-year estimate,
or revert back to an annual reporting, as allowed by Condition
11.B.2.a.3(a) of the operating permit. Based on the results listed in Table
1 of the report, NMOC testing will be repeated in 2028, and another
five-year estimate of NMOC emissions report will be generated in the
year 2028 for the period of 2028 through 2032.

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. The nitrogen content of the samples
was <20%, and the oxygen content was <5%. Projected emissions are
less than the 34/50 Mg/year trigger.

RECOMMENDATION: The test result for NMOC of 99.3 ppmv as hexane appears to be
acceptable.

HPV: No.

EXECUTIVE SUMMARY
The City of Logan Landfill (City) has developed this report regarding Tier 2 landfill gas testing and a
five-year estimate for non-methane organic compound (NMOC) emissions at the Logan Landfill
(Landfill), as required by Federal New Source Performance Standards (NSPS) for Municipal Solid Waste
Landfills (40 CFR Part 60, Subpart WWW, Sections 560.750 through 560.759 and equivalent 40 CFR
Part 62, Subpart OOO) and their Title V Operating Permit number 500103004. This report contains
resultsof the Landfillgastestingconducted inSeptember2023, and NMOCemissionsestimatesforthe
five-year period beginningJanuary 1, 2023, and ending December 31,,2027.|f the estimated NMOC
emission rate is less than 34 megagrams (Mg) per year in each of the next five consecutive years, the
owner or operator of the landfill may submit an estimate of the NMOC emission rate for the next
five-year period in lieu of reporting annually.
Kleinfelder lnc. (Kleinfelder) conducted landfill gas testing at the Landfill on September 13-22,2023.
Testing was conducted to assess the site-specific value for the concentration of non-methane organic
compounds (Crurvroc) contained in the landfill gas, in accordance Condition 11.8.2.a.1-(c) of the Operating
Permit. Testing involved collecting landfill gas from 25 locations from below the Landfill cover using
subsurface sampling probes, which were composited into nine Summa@ canisters. Sample collection and
analyses conformed to the approved methods described in the Test Protocol (Kleinfelder Document
No. S1C23R156796), approved for this project by the Utah Division of Air Quality (UDAQ), dated
August 7,2023.
United States Environmental Protection Agency (EPA) Landfill Gas Emissions Model (LandGEM)
Version 3.02 was used to estimate future NMOC emissions. The landfill gas NMOC laboratory analytical
result of 99.3 parts per million by volume (ppmv), and a conservative estimated waste acceptance
growth rate of 4 percent annually for the next five years (2023-20271, was input to the LandGEM model
and used to estimate NMOC emissions for the next five years. Projected NMOC emissions estimates
from the model run are provided in Table 1.

2 INTRODUCTION
2.I SOURCE DESCRIPTION
The Logan Landfill is an active Class I municipal solid waste (MSW) landfill that is owned and managed by
the City of Logan. The Landfill area containing waste that has been in place for two or more years
consists of approximately 30 acres (12.L hectares) of land in Cache Valley, Utah. For this project,
sampling will be performed across the portions of the Landfill that contain waste over two years of age,
which meets the sampling requirements of Condition 11.8.2.a.1(c) of the Operating Permit.
A site map of the facility is provided as Figure 1.
2,2 TESTING OVERVIEW
Kleinfelder conducted landfill gas testing at the Landfill on September 14 through September 22,2023.
Testing was conducted to assess the site-specific value forthe Crur,,roc contained in the landfill gas in
accordance with federal and UDAQ rules. Site-specific Cr.rrvroc was calculated using Tier 2 testing
provisions as provided in Condition 11.8.2.a.1(c) of the Operating Permit. Sampling conformed to
techniques and approved methods described in the Test Protocol approved for this project by UDAQ in
correspondence dated September 15,2023. The text ofthe approved Test Protocol is provided as a
reference in Appendix A.
2.3 REGULATORY OVERVIEW
Testing was conducted to assess the site-specific value forthe Cr,rn,1oc contained in the landfillgas. The
Crurraoc v?lu€ was used to estimate annual NMOC emission rates using EPA's LandGEM model. lf the
estimated NMOC emission rate is less than 34 Mg per year in each of the next five consecutive years,
the owner or operator of the landfill may submit an estimate of the NMOC emission rate for the next
five-year period in lieu of reporting annually. This report contains NMOC emissions estimates for the
five-year period beginningJanuary L,2023, and ending December 31,2027. Historicalwaste in place,
along with projected waste in place for 2023 through 2027 were used to estimate projected future
NMOC emissions. A full description of NMOC emissions estimation procedures is discussed in Section 4
of this report.

2.4 TEST MODIFICATIONS
Backup samples were collected in two canisters (LLFD-I and LLFD-2). Landfill gas probe locations and
depths were adjusted to prevent ambient air intrusion into the samples and based on conditions
observed at the Landfill. The depth of each of the probes was located within waste that had been in
place for at least two years.

3 TIER 2 IANDFIIL GAS TESTING
3.1 OVERVIEW
Sampling and analysis were conducted in accordance with Condition 11.B.2.a.1(c) of the Operating
Permit, and the approved Test Protocol. Field sampling activities were completed within three days at
the Landfill. A representative of UDAQ was not present during testing procedures.
3.2 LANDFILL GAS SAMPLING PROCEDURES
Landfill gas samples were collected by withdrawing gas from below the cover of the Landfill using
subsurface sampling probes. Sampling probes were hydraulically pushed into the solid waste using a
mobile direct push drill rig. A total of 25 probes were advanced (at least one meter below the cover
material) within the waste that was at least two years old to depths of approximately 10 to 20 feet
below the Landfill surface. Approximate probe locations are identified on the Site Map provided as
Figure 1.
Polyethylene tubing was attached to the sampling probe tip for extraction of landfill gas at each probe
location. The sample locations were screened for nitrogen, oxygen, carbon dioxide, and methane
content in landfill gas using a Landtec' GEM5000 portable gas analyzer. lf screening indicated that
nitrogen and oxygen were detected at concentrations exceeding 20 percent and/or 5 percent,
respectively, the probe location was abandoned, and another location was selected nearby. This
field-screening procedure was conducted to ensure that landfill gas was comprised in the samples and
reduce potential intrusion of ambient air from the Landfill surface that could dilute the gas samples.
Prior to sample collection, each canister was given an initial vacuum check and the initial vacuum
measurements were recorded on the field data sheets in inches of mercury (Section 3.1, Table 3).
Following the successful screening of a sampling location and purging the sampling train, a three-way
valve was opened, allowing landfill gas to flow into an evacuated six-liter Summa@ canister attached to
the sampling train. Sampling rates were adjusted by a needle valve and monitored using a rotameter
incorporated into the sampling train. Approximately one liter each of gas volume from three separate
sample locations was composited into each canister, except for samples LLF-7 and LLF-9, that each
contained samples from two locations instead of three. Tracking time and flow rate, sample volumes
from each location were approximately equal as they were composited into the canisters. Following

completion of the sample collection at each probe location, the sampling train was purged with helium
to avoid cross-contamination. Probe tubing was discarded after use at each probe location. Field data,
including gas screening results and Summa canister control forms, are provided in Appendix B.
Final vacuum measurements were recorded for each canister following sample collection at each
location. Canisters were not completely filled with landfill gas but were left under a slight vacuum as a
quality control mechanism to be able to assess if leakage had occurred during shipment to the analytical
laboratory. Each canisterwas verified as received under negative pressure by the laboratory and were
considered as valid for analysis. Canistervacuum is discussed furtherin Section 3 of this report.
A total of 25 samples of landfill gas were composited into nine Summa@ canisters. Landfill gas samples
were collected in two additional backup canisters and assigned sample lDs LLFD-1 and LLFD-2. Nitrogen
and oxygen concentrations from sample canisters LLF-7 and LLF-8 did not meet the required quality
control parameters, therefore results from backup canisters LLFD-1 and LLFD-2 were used instead of
LLFD-7 and LLFD-8.
3.3 LABORATORYANALYTICAL PROCEDURES
11 total (9 primary and 2 backup) Summa@ canisters were shipped to Air Technology Laboratories under
chain-of-custody documentation. The samples were analyzed by EPA Reference Method 25C, which
specifies sample analysis through gas chromatography using a flame ionization detector (GC/FlD). The
concentrations of NMOC are reported as total ppmv carbon and then divided by six to provide a
reported ppmv concentration as hexane, as specified by Condition 11.B.2.a.1(c) of the Operating Permit.
These results are presented in Table 2 in Section 2.4 of this report.
Method 25C requires that samples be analyzed by EPA Reference Method 3C for calculation of nitrogen
and oxygen as a percentage of the total sample (U.S. EPA, 2OL7). The criteria for acceptance as specified
in Section 4.4 of Method25C, is less than 20 percent nitrogen. The EPA has since recognized that landfill
gas may contain greater than 20 percent nitrogen if waste is in the initial stages of decomposition.
Therefore, EPA allows the measurement of oxygen content as an alternative to nitrogen, with
concentrations below 5 percent oxygen being deemed valid samples even if nitrogen exceeds 20 percent
in the same sample (U.S. EPA, 2017). Nitrogen and oxygen concentrations from canisters LLF-7 and LLF-8
were not acceptable and therefore the backup samples were used. Method 25C and 3C analytical data
are provided in Appendix C.

3,4 LABORATORY ANALYTICAL RESULTS
The landfill gas samples were analyzed by Air Technology Laboratories in accordance with EPA
Method 25C. Sample results yielded the following average Cr,rrvroc value as carbon, reported in ppmv:
o Total sample average Cr,rrvroc irS carbon = 596 ppmv.
The average Cr'rrr,1oc ds carbon is divided by six and reported as hexane, as specified by
Condition 11.8.2.a.1(c) of the Operating Permit:
o Total sample average Cxyq6 ?s hexane = 99.3 ppmv.
The site-specific Cr.rnoc value of 99.3 ppmv will be used by the Landfill for annual calculation of NMOC
emissions from the Landfill as specified by Conditions 11.8.2.a.1(a) and (c) of the Operating Permit. This
Cr'rn,loc vdlu€ may be used for five years, after which another Tier 2 test must be performed in accordance
with Condition 11.8.2,a.1(c)(3) of the Operating Permit. Analytical results of Tier 2 testing at the Landfill
are summarized in Table 2.

* = Canisters are shipped from the laboratory containing one liter of helium in order to render the return
shipment of landfill gas samples as non-hazardous. lnitiai pressures would normally reflect higher numbers if
helium was not used.
Vacuum data presented in Table 3 suggests no leaks occurred during shipment. Higher laboratory
receipt vacuums were reported, as compared to final pressures recorded by Kleinfelder before shipment
from the field. This is due to differences in altitude and corresponding atmospheric pressures between
the Landfill elevation (approximately 5,080 feet above sea level) and the elevation at Air Technology
Laboratories (approximately 150 feet above sea level).

5.2 PROJECTED WASTE IN PLACE
Future waste acceptance rates (2023 through 2027) have been estimated using a conservative annual
rate increase of4 percent. The average annual waste acceptance rate from the most recent ten-year
period of 2OLLthrough 202!is 2.4 percent. Therefore, the assumed future annual growth rate of
4 percent is considered conservative. The projected waste acceptance rates for 2023 through 2027 are
included in Table 5.

5.3 DESCRIPTION OF LANDGEM MODEL
The U.S. EPA's LandGEM Version 3.03 was used to estimate NMOC emissions. LandGEM is based on a
first-order decomposition rate equation for quantifying emissions from the decomposition of landfilled
waste in MSW landfills. The LandGEM software was obtained from EPA's website (EPA, 2O2O).
Variables used in the LandGEM model are as follows:
o k = methane generation rate constant, per year. The methane generation rate used for this
report was 0.02 per year, which is the Clean Air Act (CAA) Arid Area default. The Landfill is
considered an arid area landfill because it is located in a region that receives less than 25 inches
of rainfall per year, as defined in Condition 11.B.2.a.1(a) of the Operating Permit.
. Lo= methane generation potential in cubic meters per megagram (m3/Mg) solid waste. The
default value of L7O m3/Mgwas used for this model, as provided in Condition 11.8.2.a.1(a) of the
Operating Permit.
o Cuuoc= Concentration of NMOC in ppmv as hexane. The value of Cuuoc reported in Section 2.4 is
99.3 ppmv as hexane.
o Methane Content value of 50 percent.

6 SUMMARY
Landfill gas testing from 25 sampling probe locations across the Landfill resulted in a Cr,rr,l1oc value of
99.3 ppmv. Testing and sample analysis was conducted in accordance with the Test Protocol, and
Condition 11.8.2.a.1(c) of the Operating Permit. This site-specific value was used by the Landfill for
calculation of Landfill NMOC emissions.
NMOC emission estimates, based upon a conservative annual waste acceptance growth rate of
4 percent for the period from 2023 through 2027 , do not exceed 34 Mg/year for any of the five years. ln
accordance with Condition 11.8.2.a.3(a) of the Operating Permit, if the actual waste acceptance rate
exceeds the estimated waste acceptance rate in any year reported in this estimate, a revised five-year
estimate will be submitted to the administrator, or the Landfill may revert to the submittal of annual
NMOC emission reports.
Tier 2 landfillgas testing will be repeated in2027. Based on the estimated2O2T NMOC emission
estimate, another five-year estimate of NMOC emissions is anticipated to be generated for the five-year
period beginning January L,2027; however, the reporting period will be evaluated at that time based on
the relevant data.

1 INTRODUCTION
The City of Logan (City) has contracted Kleinfelder, lnc. (Kleinfelder) to provide Tier 2 emissions testing
services at the Logan Landfill ("Landfill"), located at 153 North 1400 West in Logan, Cache County, Utah.
The facility operates under Title V Operating Permit (#500103004). The testing will be conducted to
assess the site-specific concentration of non-methane organic compounds (Crur,roc) within landfill gas
generated at the Landfill. The results of this testing will be used to estimate the annual NMOC emission
rate from the Landfill and to assess the need for a landfill gas collection and control system (LGCS), as
required by the Landfill's Title V Operating Permit and federal New Source Performance Standards
(NSPS)for MunicipalSolid Waste Landfills (40 CFR Parl62, Subpart OOO). Sampling and analysis will be
conducted according to 40 CFR Part 60 Appendix A, Methods 25C and 3C.
T.L SOURCE DESCRIPTION
The Logan Landfill is an active Class I municipal solid waste (MSW) landfill that is owned and managed by
the City of Logan. The Landfill area containing waste that has been in place for two or more years
consists of approximately 30 acres (12.1. hectares) of land in Cache Valley, Utah. For this project,
sampling will be performed across the portions of the Landfill that contain waste over two years of age,
which meets the sampling requirements of Subpart OOO.
A Site location map of the facility is provided as Figure 1.

2 TESTPROGRAM
2.L GENERAL PROCEDURE
The Cr.rrvocwill be assessed through analysis of landfillgas samples collected from temporary borings
advanced across the Landfill. Borings will be advanced to an approximate depth of 15 to 25 feet below
the landfill cover across the landfill area where waste has been in place for two-plus years, in
accordance with Environmental Protection Agency (EPA) Method25C. Figure 2 presents the proposed
approximate landfill gas sampling locations. A 2.5-inch diameter direct-push drill rig will be used to
advance the borings and obtain the samples. The methane, nitrogen, oxygen, and carbon dioxide
content of the gas will be screened using a portable landfill gas analyzer (Landtec" GEM5000 or
equivalent) prior to sampling to screen the samples for the quality control (QC) criteria referenced in
EPA Method 25C. The NMOC samples will be collected into the sampling containers through the
post-run tubing (PRT) system connected to the direct-push drill rig (described in Section 2,3).
Landfill gas samples, approximately one-liter in volume, will be collected from each sample location at a
rate not to exceed 0.5 liters per minute, measured through a rotameter, into a six-liter Summao
evacuated canister (note that at the Site altitude, approximately 5,100 feet above sea level, the effective
canister volume will be reduced to approximately five liters).
Results of laboratory analyses will be used for estimation of the Site-specific Cr.rrvoc.
2.2 SAMPLING LOCATIONS
Tier 2 sampling, under Subpart OOO, requires sample collection from at least two boring locations per
hectare of landfill surface that has waste in place (WlP) over two years of age. lf the landfill area to be
tested is largerthan 25 hectares, a maximum of 50 sample boring locations are required. The Landfill
currently has approximately 12.1 hectares of potentially gas producing MSW. Twenty-five locations will
be sampled from WIP greater than two years at depths ranging from approximately 1-5 to 25 feet below
the landfill surface. Deeper borings may be required to reach eligible waste and prevent ambient air
intrusion. Depth of the borings will be based on the landfill gas screening results at the time of the
testing.

Sample boring locations will be arranged to represent an even distribution of sample locations over a
current map of the Landfill area where waste has been in place for two years or more. Sample locations
will be marked in the field prior to sampling using survey lathe and flagging tape. Sample probe locations
may be adjusted within the flagged area if field gas screening results do not meet the quality control
criteria for Method 25C, if the probe is rejected by debris in the landfill, if insufficient gas is available for
sampling, or if subsurface landfillgas collection infrastructure is present in the boring location. The
sample probe locations may also be adjusted due to unsafe conditions, such as site inaccessibility, active
landfilling operations, and/ or steep terrain profiles on the side slopes. Typically, air infiltration through
temporary slope sidewall cover may contain landfill gas that may not pass the QC requirements of
Method 25C. Forthese reasons, proposed sampling locations will be concentrated on the relatively
flatter accessible portions of the Landfill. Approximate landfill gas probe locations are provided on
Figure 2.
2,3 MODIFIED METHOD 25C
Sample collection and analysis used to assess the Curvoc in the landfill gas will be conducted in
accordance with EPA Method 25C, with the following modifications noted in this section.
Landfill gas samples will be collected through the PRT system as illustrated in Method 25C. A schematic
of the Method 25C sampling system is provided as Figure 3. The PRT system consists of a hollow steel
drive rod and sampling head equipped with an expendable drive point to assist with placement by
direct-push methods, When the probe has reached the desired depth, the drive rod is pulled up
approximately six to twelve inches to create a small headspace, leaving the end of the probe open for
sample collection. A%-inch polyethylene tube is then inserted through the center of the drive rod and
connected to the sampling head by an airtight threaded fitting. Gas is then withdrawn though the
tubing. A schematic of the post-run tubing system is provided with this Protocol in Appendix A. The
post-run tubing system will be placed using the direct-push type drilling rig.
The %-inch polyethylene sample tubing will be connected to a stainless-steel flow control manifold
containing a fine-flow controller, a flow-indicating rotameter, and a three-way purge/sample valve. The
Summa' canister will be attached to the sampling train behind the purge/sample valve. Prior to
sampling, the landfill gas analyzer (Landtec@ GEM5000 portable landfill gas analyzer or equivalent) that
is connected to the purge side of the three-way valve will be used to draw LFG through the probe and
tubing. A minimum of two sample tubing volumes of LFG purged through the sampling train prior to
collection of the samples. The landfill gas analyzer will be used to assess if the nitrogen content of the

landfill gas 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.
A minimum one-liter landfill gas sample from each location will be drawn through the sampling train and
into a six-liter Summa' canister at a sampling rate not to exceed approximately 0.50 liters per minute.
lndividual samples from three sampling locations will be composited into one canister, as allowed by
Subpart OOO. Landfill gas may contain explosive levels of methane; therefore, the canisters are shipped
from the laboratory containing approximately one liter of helium. This is done to inert the final sample
to avoid hazardous shipment procedures when returning samples to the laboratory. Combined with the
reduced effective volume of the canister due to the Landfill altitude and a need to ship the canister
under a slight negative pressure, a maximum of three sample locations will be composited into each
canister. The sampling train will be purged with helium between each boring and canister to prevent
cross-contamination between sam ples.
Summa' canisters are cleaned, polished, and leak-checked prior to shipment from the laboratory.
Vacuum readings will be recorded prior to and immediately after sampling at each location, 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 3.2 of this Test Protocol.
Samples from the 25 probe locations will be collected in a totalof nine Summa'canisters, Each of the
nine composite-sample canisters will be analyzed for NMOC in triplicate as required by Method 25C. The
analytical results from the canisters will be averaged to estimate the average Cr.rvroc (as carbon) of the
landfill gas. The Cruuoc as carbon (reported by Method 25C) will be divided by six and reported as hexane
for calculation of NMOC emissions from the landfill facility, as specified in Subpart OOO regulations.
2.4 METHOD 3C
EPA Method 3C will be used primarily to evaluate the percentage of nitrogen and oxygen in each
composite 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 many landfills 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 in the field using the landfill gas analyzer to minimize the potential for sample
rejection due to excessive nitrogen or oxygen content.

3.1 CALIBRATIONS
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 SUMMA. CANISTERS
Summa' 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
-L8 to -21 inches Hg at the Landfill altitude).
The canister vacuum will be recorded prior to and immediately after sampling at each probe location.
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, or
vacuum, 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 upon laboratory receipt 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 chain-of-custody.

3.3 DATA COLLECTION
Field data sheets will be maintained throughout the sampling event. At each sample location the
following data will be recorded:
o Probe (boring) identification number,
. Probe location, if relocated due to conditions specified in Section 2.2,
. Landfill gas parameters during the purge process,
o Pre-and post-sample canister pressure measurements,
o Canister serial number, and
o Sampling start and end times.
Additionally, the following data will be recorded on the field data sheets:
o Ambient temperature ('F), and
o General weather conditions.
Samples collected will be handled under general chain of custody requirements, in accordance with
standard environmental sampling protocol.
3,4 LABORATORYANALYSIS
Method 25C and Method 3C each have Quality Assurance/Quality Control (aA/aC) requirements
pertaining to gas chromatograph operation and calibration. The selected analytical laboratory will
adhere to QA/QC requirements, as specified by the methods. Relevant AA/aC data will be included in
the test report.
3.5 BACKUP SAMPLES
Two extra Summa" canister will be kept in reserve in case a replacement canister is needed. An
additional landfill gas sample will be collected from every fifth sampling probe location and composited
into the extra canisters, creating two backup samples from the 25 sampling locations which will be
representative of the gas samples composited into the other canisters. The backup canisters 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 nine sample canisters fails quality control parameters due to intrusion of
ambient air (i.e., nitrogen greater than 2OoA or orygen greater than 5%), then the backup canister(s) will
be submitted as a replacement for analysis.
