Dear Mr. Fitzgerald:
Your f icility recently conducted source testing on 22 September 2009 to determine the concentration and flow rate of
non-methane organic compounds(NMOC) iron the landfill. A written test protocol was submitted in August will) a
tentative(late in October of 2009. III bold in this same box(2.9), it states"DAQ Regional Supervisor must be notified
at least 15 days prior to the actual test date(s)". Note this is also required by North Carolina regulation NCAC2D
.2602(d)-this 15 day advance notification to this Office is to allow observation of the test. fit phone conversations
this week with you and Mr.Kitrt Shaner, it appears that ill the rush to test this notification was overlooked However,
a key element of our inspection during source testing is the recording of the operating parameters under which the test
was conducted. This information is used to evaluate the source test data as well as to assist in determining future
compliance.
Please provide this office, prior to 3 November 2009,the following information related to the testing:
1. the NMOC Flow rate and landfill pressure readings(strip charts and/01 any other onsite ololutoring data
collected for the landfill equipment) For21,22,and 23 September 2009;and
2, according to the test report submitted, there was a 4°i(backup)sample collected during the testing. Please
provide the results of the analysis for NMOC concentration that was conducted on this 4u'(backup)sample.
The Division strongly recommends that you carefully examine your current permit and request explanation front this
Office as necessary. If you have any questions regarding this matter,please call Mitchell Revels, Robert Ilayden, or
tine at(910)433-3300.
Sincerely.- )

Dear Mr. Vozzo,
On behalf of Chambers Development of North Carolina and the Anson Waste Management
Facility(AWMF), SCS Engineers,PC (SCS)is pleased to submit the requested additional
information related to the above referenced project. In a letter dated October 23,2009, the
Fayetteville Regional Office of the Division of Air Quality requested additional information
pertaining to the site-specific NMOC testing conducted at the site by SCS Engineers. In general,
the October 23,2009 letter requested(1) flare operational data and(2) laboratory analysis from
the 4'h sample of landfill gas collected during the NMOC test.
Following receipt of the October 23, 2009 letter, SCS contacted the Fayetteville office to clarify
what system data was being requested. In a discussion with Mr. Robert Haydon at the
Fayetteville Regional Office, it was determined that the attached flare data from the data logger
would be sufficient to satisfy the October 23rd request. The attached system information was
taken from the flare's data logger and includes the landfill gas flow and temperatures at the flare
during the NMOC sampling. The flow and temperature data at the flare are recorded every four
minutes by the data logger. Additionally,daily flow and temperatures are shown for
approximately a week before and after the test.
The fourth sample of landfill gas was never tested by the laboratory. The 4 h sample was taken
as a backup incase an air leak occurred in one of the primary samples that would nullify the data.
For this Tier II NMOC test,the three samples were representative landfill gas samples that met
the requirements specified in the testing protocol so the backup gas sample was never tested.
This was communicated to Mr. Hayden of the Fayetteville Regional office and it was discussed
that testing the 4th sample was not necessary.

SCS and the landfill apologize for not notifying the Fayetteville office 15 days prior to the
NMOC testing at the site. We hope this additional information answers any questions you have
with the NMOC test. If you have any additional questions or need more information,please feel
fiee to call either of the undersigned at(704) 504-3107.
Very trulyyours,

INTRODUCTION
On March 12, 1996, the Environmental Protection Agency(EPA) promulgated the New
Source Performance Standards (NSPS) and Emissions Guidelines (EG)for new and
existing landfills under Section III (b) of the Clean Air Act(CAA). The basis for this
legislation is EPA's determination that municipal solid waste (MSW) landfills contribute
' significant amounts of air pollution that is potentially detrimental to public health. The
NSPS are intended to control non-methane organic compound(NMOC) and
methanogenic emissions from MSW landfills. NMOCs include volatile organic
compounds (VOCs), hazardous air pollutants (HAPs), and odorous compounds. The
NSPS applies to landfills having a design capacity greater than 2.5 million Megagrams
(Mg) (or 2.75 million tons) that were permitted, modified, or reconstructed after May 30,
1991.
Chambers Development of North Carolina, Inc. owns and operates the Anson Waste
Management Facility (Landfill). The landfill also operates a"voluntary" landfill gas
(LEG) collection and control system (GCCS) located on the site. The collected landfill
gas is destroyed in an onsite utility flare. The landfill is regulated under the NSPS based
upon having a design capacity exceeding 2.5 million Mg.
Section 60.757(c)(1) states that if the Tier 1 analysis results in NMOC emissions greater
than 50 Mg per year(a Tier 1 test was previously performed at the Landfill by SCS
Engineers on May 15, 2009, the landfill failed the Tier 1 test), therefore, a site-specific
Ter 2 NMOC emissions rate report must be completed. The results of the Tier 2 test will
yield a site-specific NMOC concentration for the LEG at the Landfill. This site-specific
NMOC concentration can be used to more accurately estimate the annual NMOC
emissions fi-om this facility and determine this facility's applicability to the NSPS.
The site-specific Tier 2 test was performed on September 22, 2009 and the results found
the LFG NMOC concentration to be 569 ppm as hexane, which resulted in a maximum
predicted annual emission rate of 61.9 Mg for the year 2014 (using the test results,
emissions are predicted over a five year period from the test(late). Tier 2 test results are
valid for a period of five years.
This report was prepared by SCS Engineers, PC (SCS) on behalf of the Anson Waste
Management Facility to quantify the NMOC emissions for compliance with the NSPS, 40
CFR Part 60, Subpart WWW, by presenting a Tier 2 sampling, analysis, and revised
NMOC emissions estimate. This report includes sections describing the field sampling
procedures and activitics, the results of the laboratory analysis, estimates of current and
projected annual NMOC emissions, and overall conclusions.

TIER 2 NMOC SAMPLING
SCS performed site-specific(Tier 2)NMOC field sampling at the Anson Waste
Management Facility on September 22,2009 in accordance with procedures outlined in
the NSPS and SOS's sampling protocol. The North Carolina Department of Environment
and Natural Resources (NCDENR) approved the methodology of the sampling protocol
prior to the field sampling(Appendix B). Copies of the SCS sampling protocol and
significant correspondence are included in Appendix A.
Field Sampling Procedures
SCS conducted Tier 2 sampling in accordance with the NSPS requirements, EPA Method
25C and EPA Method 3C. This NMOC Emission Rate Report was also prepared in
accordance with the above mentioned emission guideline requirements. Tier 2 samples
were collected from a sampling port on the GCCS that is located upstream of the
generators, flare,blower, and skid-mounted condensate knock-out pot such that the gas
samples collected will be representative of LEG from the landfill mass. Samples will be
drawn from the main header by vacuum into six-litter, stainless steel "SUMMA"
canisters. The SUMMA canisters were supplied by AtmAA, Inc. laboratories and
certified to be clean and under vacuum. The sampling train included sampling tubing,
flow control valve, flow measurement gauge, and a two-way valve directing the sample
either into the sampling canister or to field instrumentation.
Three samples of LEG were collected and a fourth sample was collected as abackup.
Tier 2 Field Sampling Activities
The Tier 2 NMOC field samples were collected at the landfill on September 22,2009.
Present during the sampling activities was J Morgan of SCS. Prior to sampling, SCS
personnel verified with Landfill personnel that the active LEG collection system was
operating normally and all applicable wells and collectors had applied vacuum at the time
of the Tier 2 test. Pursuant to the above referenced sampling procedure, four
representative LEG samples were obtained from the main header upstream from the
existing blower and condensate knockout. The sampling location is shown on a figure in
Appendix C.
All four LEG samples were obtained from the same sample port on the main header and
in an identical manner. Field equipment used during the sampling activities included a
LandTec R GEM-2000 Infrared Gas Analyzer, an EPA Method 25 C approved sampling
valve train with an attached digital pressure gauge, and three 6-liter stainless steel
SUMMA sample canisters. In accordance with EPA Method 25 C, the sampling
apparatus was connected to the header sample port, checked for leaks, and then purged of
ambient air using the GEM 2000 unit.
Once LEG readings within the limitations allowed by EPA Method 25C were verified by
use of the GEM 500, approximately three liters of LEG was collected, at a rate of 250

ml/min, in each SUMMA canister. SCS performed a leak check during the sampling by
closing the sample train valve and allowing the SUMMA canister to apply vacuum to the
sample train alone. During all runs the leak test indicated no leaks in the sample train.
An individual SUMMA canister was used for each of the four LEG samples.
SCS shipped the four LEG sample SUMMA canisters via Federal Express to AtmAA
Laboratory of Calabasas, California, for subsequent analysis in accordance with EPA
Method 3C and 25C. Appendix D contains the Tier 2 sampling logs and AtmAA chain
of custody form.
TIER 2 NMOC LABORATORY ANALYSIS
A laboratory analysis of the LEG samples was performed by AtmAA using EPA Methods
25C and 3C. Measured NMOC concentrations from the SUMMA canisters were
corrected for moisture,nitrogen, and pressurization of the canister. SCS provided AtmAA
with the field conditions (temperature and barometric pressure) at the time of LEG
sampling to achieve an accurate calculation of the NMOC concentration. AtmAA
performed these calculations and equipment calibrations as documented in Appendix E.
The laboratory results (shown in Table 1) were close in range, which, statistically, leads
to a high probability that the three samples reflect the actual NMOC content of the LEG.
The average NMOC concentration of the three samples is 3,416 ppmv (reported as
carbon).
Since the EPA Landfill Gas Emissions Model (LandGEM) requires the input of the
NMOC concentration in terms of hexane, the laboratory NMOC concentration was
converted to hexane by dividing by six. This resulted in an average NMOC concentration
of 569 ppmv as hexane. This site-specific NMOC concentration is used in evaluating the
revised NMOC emissions.

TIER 2 NMOC EMISSION ESTIMATES
The Tier 2 NMOC emissions estimates for the Landfill were performed using SCS's
spreadsheet version of the EPA LandGEM Model. The model inputs established in
Section 60.754(a)(1), the average NMOC concentration, and the refuse fill history of the
facility were used to perform the Tier 2 model and are as follows:
e Methane Generation Potential (Lo)— 170.0 m3/Mg. (Default value cited by NSPS)
e Methane Generation Rate Constant(lc)—0.05/year. (Default value cited by NSPS)
e NMOC Concentration— 569 ppmv as hexane. (Field sampling value)
e Refuse Filling History—SCS used tonnage records provided by the Landfill. Future
annual waste volumes were also supplied by the Landfill. The fill history is shown
in the LandGEM model output in Appendix F.
According to the EPA LandGEM Model, the 2009 NMOC emission rate for the Landfill
is 43.9 Mg/year(or 48.3 tons/year). The maximum annual NMOC emission rate
predicted over the next five-year period will be 61.95 Mg/year(or 68.2 tons/year) in the
year 2014. A copy of the Tier 11 model output is included in Appendix F. The results of
the model are summarized below in Table 2.

SUMMARY
The 2011 NMOC emissions estimate is above 50 Mg/year, therefore, one of the
following options must now be implemented:
Conduct Tier 3 methane generation rate sampling and analysis as provided in 40
CFR 60.754(a)(4) in hopes of lowering the methane generation rate constant(k);
or
Submit a NSPS GCCS Design Plan prepared by a professional engineer within
one year of the emissions exceedance date in accordance with 40 CFR
60.752(b)(2)(i), namely September 4, 2012. Installation of the GCCS must be
completed within 18 months after the submittal of the Design Plan (February 4,
2014).
It should be noted that Tier 3 testing can be a costly process that often does not produce
the desired results (i.e., significantly lower the site's NMOC concentration). For these
reasons, SCS does not recommend a Tier 3 test for the Anson Waste Management
Facility.

Dear Mr.Vozzo,
On behalf of Waste Connections of the Carolinas and the Anson Waste Management Facility (AWMF)
SCS Engineers(SCS)is pleased to submit a testing protocol for Tier 2 sampling at the AWMF. The
AWMF is regulated according to the U.S.Environmental Protection Agency's(EPA's)New Source
Performance Standards(NSPS)for Municipal Solid Waste Landfills.
Per the NSPS regulations, SCS prepared a Tier 1 NMOC Rate Report for the Facility using US EPA's
LANDGEM Landfill Gas Emission Model(v3.02)and Tier 1 NSPS default values. The calculations
indicate that the Facility will generate over 300 Mg per year of NMOC emissions in year 2009 with
increasing amounts every year thereafter. This rate is greater than the regulatory NMOC emission
threshold of 50 Mg per year,as defined in 40 CFR 60.752(b)(1)(ii)(A), Per 40 CFR 60,754(a)(2)(ii),the
Facility should perform a Tier 2 NMOC emission test to obtain site-specific NMOC data. The Tier 2 test
shall be performed upon the NCDENR approval of the testing protocol,and the final Tier 2 NMOC
Report will be submitted to the NCDENR.
Accordingly, SCS has developed a sampling program to determine the site-specific NMOC concentration
in the LFG at the landfill. SCS proposes to collect three composite LFG samples from the existing
landfill gas collection and control system. A complete discussion of the proposed sampling program is
included as Attachment A for your review and approval.

II. TEST OBJECTIVES
The objective of this site-specific test is to quantify the non-methane organic compound
(NMOC)emissions for compliance with 40 CFR Part 60 Subpart W W W, Standards of
Performance for Municipal Solid Waste Landfills. Per 40 CFR 60.754(a)(2)(ii), the Facility
should perform a Tier 2 NMOC emission test to obtain site-specific NMOC data. The Tier 2 test
shall be performed upon the NCDENR approval of the testing protocol. The results of the Tier 2
test will yield an updated site-specific,NMOC concentration in the landfill gas(LFG) at the
Landfill. This NMOC concentration will then be input into a model to estimate the NMOC
generation at the Landfill.
Ill. PROCESS DESCRIPTION
SCS Engineers (SCS)has developed a sampling program to establish the site-specific NMOC
concentration in LFG for the NSPS Tier 2 NMOC emission rate calculations.
Existing LFG Collection and Flaring System
The Landfill's currently constructed footprint is approximately 40 acres. The Landfill has an
active LFG collection and control system(GCCS)which consists of 15 vertical extraction wells,
several LFG condensate sumps,header and lateral piping, and a 2,500 scfm Zink utility flare. A
site map is provided as Attachment B. The utility flare is permitted by NCDENR and the Air
Quality Permit number for the site is 098351100.
Al
i

The vertical extraction wells are connected via laterals to one main header that conveys the
withdrawn LFG through the blower to the flare. All header and lateral piping is SDR 17 HDPE
pipe installed below grade.
LFG is collected and transported via the laterals to the LFG flare skid. The LFG flare skid
contains blowers, condensate removal equipment, and various control valves and monitoring
devices.
IV. SAMPLING AND ANALYTICAL PROCEDURES
The sampling and analytical procedures are presented below.
`filer 2 Sampling Protocol
SCS will conduct Tier 2 sampling and prepare an NMOC Emission Rate Report in accordance
with the NSPS requirements, EPA Method 25C and EPA Method 3C. Tier 2 samples will be
collected from a sampling port on the GCCS that is located upstream of the flare,blower, and
skid-mounted condensate knock-out pot such that the gas samples collected will be
representative of LFG from the landfill mass. Samples will be drawn from the main header by
vacuum into six-liter,stainless steel, "SUMMA"canisters. The SUMMA canisters will be
supplied by the testing lab and certified to be clean and under vacuum. The sampling train will
include sampling tubing, a flow control valve, a flow measurement gauge, and a two-way valve
which directs the sample either into the sampling canister or to another device(i.e., field
instrumentation).
LFG quality will be measured and recorded using a LandTec GEM 2000 infrared gas analyzer
prior to collecting each LFG sample. The purpose of this measurement is to purge the volume of
gas inside the sampling train, and verify that there are no leaks in the sampling train and that
oxygen and nitrogen concentrations in the LFG are less than 5 percent and 20 percent,
respectively.
SCS will conduct a leak check on each SUMMA canister using a dial manometer upon receipt
from its laboratory to ensure proper vacuum. A second canister leak check will be performed on
each SUMMA just prior to sampling,using the digital manometer on the sampling train. SCS
will use the GEM-2000 instrument to sample the LFG prior to sampling to ensure no leaks in the
sample train. A final leak check will be performed during sampling to check for leaks in the
sample train. This check involves closing the inlet valve from the LFG header and monitoring
the digital manometer for two minutes. If the negative pressure continues to fall, SCS will know
that the sampling train has a leak. These checks will be recorded in the sampling forms and
provided to SCDHEC in the final report. A copy of SCS'S sampling form is included as
Attachment D.
A total of three sequential LFG samples will be collected for laboratory analysis. A fourth
sample will be collected as a backup sample immediately after the primary samples and will be
analyzed only if primary samples are damaged through shipping or laboratory procedures. Per
i
A-2

1
Method 25C,the maximum sampling rate will be 500 ml/min. SCS will verify that the sampling
rate is below 500 ml/minute by using a digital manometer to check sample canister pressure.
SCS will check the canister pressure prior to and immediately after sampling, and then compare
the amount of canister vacuum used with the sampling time. SCS will also use a rotameter,
which is a flow measurement device,to check the flow rate during sampling. Approximately
five liters of composite sample will be obtained per SUMMA canister for a total of 15 liters of
sample. It is estimated that the sampling duration will be approximately 10 minutes per canister,
for a total of 30 minutes of sampling for three sample canisters.
According to SCS's laboratory subcontractor,EPA Method 25C samples taken in stainless steel
SUMMA canisters have a"shelf-life"of 30 days. SCS intends to ship the samples in DOT-
approved boxes to our laboratory via overnight courier within one day of sampling. Should the
canisters require storage overnight prior to shipment, they will be stored in a cool location, away
from heat sources.
At the laboratory,the samples will be stored and analyzed within the guidelines of Method 25C
(total NMOC analysis)and Method 3C (nitrogen/oxygen analysis). The laboratory typically
begins analysis within five days of receipt of samples. The laboratory will observe the
following standards:
® The lab will use the minimum detection limits specified by EPA Method 25C.
® The lab will use guidelines found in EPA Method 25C for range of recoveries and data
interpretation.
The lab and SCS will use the methods for the various blanks required by EPA Method
25C. Method blanks are run at a minimum of 1 per batch of 20 samples or every 24
hours, whichever is more frequent. All target analytes are required to be below the
practical qualification limit(PQL).
® The lab will follow all calibration frequencies,ranges, and acceptable limits listed in
EPA Method 25C. This consists of an initial calibration of at least 4 points per range
(0.0010 to 1.0%, 0.50 to 100%). Percent RSD for each compound must be less than 20
percent. This calibration is performed initially and as required if continuing calibration
fails. Continuing calibration is a single midpoint performed at the beginning and end of
each analytical batch with each batch not to exceed 20 samples or 24 hours. Criteria
are+or—20%difference for each compound of interest.
Rationale for Using LFG Data from Existing LFG Collection System
Section 60.754(b)(2) of the NSPS specifies that the NMOC concentration be analyzed by
sampling from a common header pipe for purposes of determining when the system can be
removed(i.e. NMOC< 50 Mg/yr). Therefore, the regulation allows landfills to sample from the
collection system when appropriate for determining NMOC concentrations. In addition, Section
60.752(b)(2)(i)(B)allows for alternatives to any part of the regulation, including test methods
(e.g., sample the flare inlet in lieu of multiple, shallow sampling probes within the refuse). The
A-3

purpose of this allowance is to accommodate practical alternatives to meet the objectives of the
Rule.
The existing LFG collection system collects approximately 180 standard cubic feet per minute
(sefin)of gas from throughout the Landfill using the extraction wells and collectors described
above and with elements installed in the leachate collection system. SCS believes that collecting
the Tier 2 samples from the main LFG header,upstream of the skid condensate knockout pot,
will provide representative LFG samples.
This approach to Tier 2 testing was approved by NCDENR for the White Street Landfill in
Greensboro,NC. Also, numerous EPA Regions at a number of other landfills across the country.
Copies of the approval letters are enclosed in Attachment E.
V. SAFETY CONSIDERATIONS
LPG contains methane and therefore is potentially explosive. SCS personnel are experienced
with landfill operations, LFG collection systems, and the proper sampling and handling of LFG.
Standard safety precautions include refraining from smoking or creating sparks near the test site
and using explosion-proof equipment. SCS will follow safety precautions outlined in EPA
Method 25C.
No special safety equipment is required for the test. However, all testing personnel will wear
clothing appropriate for a landfill environment such as steel-toed boots and long pants. Hard
hats, ear protection,and eye protection are not specifically required by the Landfill at the testing
site;however, all testing personnel will have such equipment available to use, as needed based
on field conditions.
VI. SAMPLING LOCATIONS
A site plan is provided in Attachment B. This plan shows the layout of the Landfill, LFG wells,
piping, and blower flare location. Attachment C provides a representative schematic of a typical
utility flare skid to indicate where sampling will occur in relation to condensate removal and
vacuum equipment.
VII. QA/QC MEASURES
SCS will follow the QA/QC requirements of the EPA Quality Assurance Handbook,Volume 3.
SCS will also follow chain-of-custody requirements of its courier(Federal Express) and its
laboratory subcontractor(ATL). A sample chain of custody form from the testing laboratory is
included with this submittal as Attachment F. This form will be completed by SCS personnel
and shipped with the samples to the lab. A copy of this form and the full results and back-up
documentation from the lab will be included in the final report to SCDHEC.

Dear Mr.Thomasson:
The emissions test protocol for the subject landfill gas collection system has been reviewed. Testing will
quantify the NMOC emissions for compliance with 40 CFR 60 Subpart W W W,Standards of Performance
for Municipal Solid Waste Landfills. The table below lists the pollutants and test methods:
Target Pollutant Proposed Test Method
Carbon Dioxide and USEPA Method 3C:Determination of Carbon Dioxide,Methane,Nitrogen,and Oxygen from

Protocol for Tier 2 Emissions Testing for Non-methane Organic Compounds of the Municipal
Solid Waste Landfill Submitted by SES Engineers, PC
Proposed Test Date: October 2009
Dear Mr. Fitzgerald:
The North Carolina Division of Air Quality (DAQ) has reviewed the protocol submittal form (PSF)
regarding emissions testing for non-methane organic compounds (NMOC) from the landfill. The
proposed testing is acceptable as discussed below.
The source is a municipal solid waste landfill with a footprint of approximately 40 acres. A landfill gas
collection and control system, consisting of 15 vertical extraction wells, lateral piping, and a 2,500
standard cubic feet per minute (scfm) flare, is currently installed on Cells 1A and 1 B. Note this system
does not control emissions from all areas where there is currently waste in place(Cells 1A through 1D).
The testing will be performed in order to demonstrate compliance with 40 CFR Part 60, Subpart WWW
Standards of Performance for Municipal Solid Waste Landfills. The regulation requires landfills with
annual emissions of NMOC greater than 50 mega grams per year(Mg/yr) to install and operate a landfill
gas collection and control system. Subpart WWW allows the landfill to estimate annual NMOC emissions
using waste in place data and/or to conduct emissions testing to develop site-specific emission rates.
Anson County Waste Management calculated Tier 1 annual NMOC emissions for the subject source
using actual waste data and default parameters specified by t1SEPA. The annual emissions of NMOC
were estimated to be 300 Mg/yr.
Anson County Waste Management now proposes Tier 2 NMOC emissions testing of the landfill to obtain
a site-specific emission rate. Testing will only be conducted on Cells 1A and 113, which is the portion of
the landfill with the gas collection and control system. The waste in these cells is older than the cells not
being tested and therefore is expected to have greater NMOC emissions. The emissions rate from Cells
i
1A and 1B will be used to calculate annual emissions for the entire landfill.

Nitrogen, and Oxygen from Stationary Sources
Non-Methane Organic US EPA Method 25C Determination of Nonmethane Organic Compounds
Compound (NMOC) " (NMOC)in Landfill Gases
Three samples will be collected from a sampling port located at the common header of the gas collection
system. The test location is prior to the blowers and condensate removal equipment. The samples will
be drawn into 6-liter certified 'SUMMA" canisters. A fourth sample will be collected as a backup sample
and only analyzed if a primary sample is damaged.
The maximum permitted gas flow rate of the gas collection system is 300 scfm. The proposed flow rate
during the test is 185 scfm, which is 62% of the maximum. The proposed rate is less than the requirement
to conduct emissions testing at 90% or greater of the maximum process rate. Anson County Waste
Management shall be responsible for ensuring, within the limits of practicality, that the gas collection
system is operated at or near the maximum normal flow rate. The final test report should include the
actual flow rate during the emission tests.
In conclusion, the sampling protocol is approved. Approval of the protocol does not exempt the tester
from the minimum requirements of the test methods. Any deviations from the methods remain subject to
approval by DAQ. If you have any questions regarding the results of this review, please contact me at
[phone] or at paula.hemmer(d)ncmail.net. '

Paula M. Hemmer
