SECTION 2 UNCOLLECTED LANDFILL GAS FUGITIVES
LANDFILL GAS FUGITIVE EMISSIONS
This section addresses the generation of landfill gas(LFG), non-methane organic compounds
(NMOCs),volatile organic compounds(VOCs)and hazardous air pollutants(HAPs),methane,
and carbon dioxide and their fugitive emissions via passive LFG releases.
LFG generation from the landfill operation was calculated using SCS Engineers' version of the
U.S. EPA Landfill Gas Emissions Model(LandGEM). A description of the model parameters is
provided below and the model output is attached.
LandGEM uses a first-order decay equation to predict landfill gas generation based on the
amount and age of the waste in place. The formula is presented in 40 CFR Part 60.754(a)(1)(i).
The parameters La and k used in the LandGEM are the values published in EPA's Compilation
of Air Pollutant Emission Factors(AP-42), Volume I, Section 2.4(revised November 1998).
The methane generation potential, L,,, for the MSW landfill cells was set equal to 100 cubic
meters(m3) of methane (CH4)per megagram(Mg) of waste. The methane generation rate
constant,k,was 0.04 yr i and the concentration of NMOC in LFG was set to 595 parts per
million by volume(ppmv)as hexane. AP-42 recommends these values of Lo and k for
municipal solid waste(MSW) landfills that are located in geographical regions that receive
average or above average annual precipitation, such as Aulander,North Carolina.
To calculate landfill emissions, the refuse filling history was input to the LandGEM. Note that
this model estimates emissions based on the amount of waste in place at the beginning of each
year. Waste in place at the beginning of 2011 was approximately 6.75 million Mg, or 7.44
million tons. The LandGEM estimated that the methane generation rate for 2011 is
approximately 20.57 million cubic meters, or approximately 726.1 million cubic feet. Assuming
that the methane content in the LFG is 50 percent, the volume of LFG generated in 2011 is
estimated to be 2,764 cubic feet per minute(ft3/min).
LandGEM input and output are provided on page 1 of the spreadsheets found at the end of this
permit.
Non-Methane Organic Compound (NMOC) Emissions
NMOC generation from the Landfill was calculated using LandGEM. Model parameters were
similar to the values noted above. LandGEM estimated that the NMOC generation rate for 2011
is 87.75 Mg, or 96.72 tons(See page 2 of the spreadsheets provided in the detailed calculations
attachment). The Landfill operates a gas collection and control system(GCCS)to capture LFG
and route it to a control flare. Seventy five percent of the LFG is assumed to be captured;
therefore,twenty five percent of the NMOC generated is assumed to have been emitted as
fugitive. Thus,the fugitive NMOC emission rate for 2011 is 24.18 tons.

East Carolina Environmental Landfill
Volatile Organic Compound (VOC) Emissions
In determining the VOC emissions from the landfill, VOC generation is assumed to be 39
percent of the NMOC generation. This assumption is based on information contained in AP-42
Section 2.4(revised November 1998)Table 2.4-2.
VOC emissions were based on the historical tonnages and model parameters noted above. The
LFG and NMOC generation rates were extracted from the LandGEM output and represent the
emissions from the Landfill during 2011. The VOC generation rates were calculated by
converting the NMOC generation rates (shown in the LandGEM output)from Mg/yr to tons/yr,
and then multiplying by 0.39(i.e., VOC is considered as 39 percent of NMOC). The VOC
generation rate for 2011 is 37.72 tons/yr. The fugitive VOC emission rate is determined is the
same manner as the fugitive emissions rate for NMOC reflecting the operation of the GCCS
during the period. The fugitive VOC emission rate for 2011 is 9.43 tons, as shown in Table 2
below.
Table 2. Air Pollutant Generation and Emission Rates
NMOC NMOC • • VOC Fugitive Fugitive
Year Generation Generation Emissions Generation, Emissions' Emissions
2011 87.75 96.72 24.18 37.72 �9.43 0.96
Notes:
VOC generation is assumed to be 39 percent of NMOC generation.
Hazardous Air Pollutant (HAP) Emissions
The estimation of HAP emissions from the Landfill is based on equations(3)and(4)of AP-42
Section 2.4. Those equations are presented below. The first step is to estimate the generation
rate of each pollutant in cubic meters per year(m3/yr). Next,the volumetric generation rate
estimate is converted to a mass generation rate(ton/yr).

Of the 188 chemical compounds identified as HAPs under Section 112 of the Clean Air Act, 28
of these compounds are listed in AP-42 Table 2.4-1 and 2.4-2. Site-specific data from testing
performed by Research Triangle Park Laboratories was used to determine the concentration of
these compounds. This report is dated May, 5,2005 and was submitted as part or the
Compliance Demonstration Report dated June 3,2005. These site specific concentrations are
shown on page 4 of the spreadsheets in the detailed emissions attachment. Annual emissions of
the remaining HAP compounds(i.e.,those not included in the AP-42 tables)are assumed to be
negligible. The HAP fugitive rate for 2011 was calculated to be 0.04 tons. Total HAP and TAP
fugitive emissions for 2011 are 0.96 tons.
SECTION 3 LANDFILL GAS FLARE
Flare Emissions
The landfill operates one flare, with a design capacity of 3,000 scfin, as a landfill gas control
device. The emission factors and annual emissions associated with the flare(permitted as CD-
Flare 1) are summarized in Table 3.

Detailed emission calculations are provided in the attachment.
Diesel Storage Tank (IES-06)
CY2011 emissions were calculated using EPA's Tank software. According to the program
0.00218 tons per year of VOCs were emitted. NMOC emissions are conservatively estimated to
be equal to VOC emissions.
Diesel Engines for Miscellaneous landfill Support (IES-04)
Emissions from the Landfill's diesel engines for miscellaneous support are"carried forward"as
allowed in the Division's AERO reporting and are therefore identical to the previous reporting
period. As reported in for CY2010, emissions are provided in Table 5:

Welding Operations ( IES-05)
The Landfill's permit also includes an insignificant activity listing for"Welding Operations"
with the emission source ID ES-05. Emissions from the Landfill's welding operations are
"carried forward"as allowed in the Division's AERO reporting and are therefore identical to the
previous reporting period. As reported in 2010, emissions of Manganese total 101 pounds.
Solar Flares (IES-08)
Three (3)solar flares were used during this period(noted here as ES-08). To estimate emissions,
flow was conservatively assumed to be 60 scfin per each flare(total of 180 scfm) for 8 hours per
day during the entire 365 day period. Based on emission rate data from a solar flare
manufacturer, Landfill Services, emissions were estimated as shown in Table 6:

OBJECTIVE:Calculate flare emissions based on LFG consumption
LFG Consumption: 979,346,976 scf/yr(CY11)
Heat Content: 500 Btu/scf
Calculated MMBTU: 489,673 MMBtu/yr(CY10)
A PPROACH:Use manufacturer data and AP42 equations and emission factors
SOLUTION:
(I)NOx Emissions
NOx emission factor= 0.068 lb/MMBtu (AP42,Table 13.5-1)
LFG consumed= 489,673 MMBtu/yr
Hours of operation= 8,760 hr/year
CMNOx=(0.068 lb/MMBtu)•(489,673 MMBtu/yr)= 33,297.8 Ib/ r NOz
CMNOx= (33,297.8 lb/yr)/(8,760 fir/yr)— 3.80 1b/hr NOz
CMNOx= (33,297.8 lb/yr)/(2,000 hr/yr)— 16.65 tn/ r NOx
(2)CO Emissions
CO emission factor= 0.37 lb/MMBtu (AP42,Table 13.5-1)
LFG consumed= 489,673 MMBtu/yr
Hours of operation= 8,760 fir/year
CMCO=(0.370 lb/MMBtu)'(489,673 MMBtu/yr)— 181,179.2 1b/ r CO
CMCO= (181,179.2 Ib/yr)/(8,760 hr/yr)= 20.68 lb/hr CO
CMCO= (181,179.2 Ib/yr)/(2,000 hr/yr)= 90.59 tn/ r CO
(3)PNt Emissions
PM emission factor= 17 Ib/l06 W CHq (AP42,Section 2.4,Table 2.4-5)
LFG consumed= 489,673 MMBtu/yr
Hours of operation= 8,760 hr/yr
HHV of natural gas= 1,020 Btu/ft3 (AP42,Section 3.2)
Equivalent amount of CH4 consumed—(489,673 MMBtu/yr)/(1,020 MMBtu/l06 ft3)= 480.07 x 106 ft'CH4
CMPM=(17 lb/million ft3 CH4).(480.07 million ft3 C114)= 8,161.2 Ib/ r PM
CMPM=(8,161.2 lb/yr)/(8,760 hr/yr)= 0.93 Ib/hr PM
CMPM= (8,161.2 Ib/yr)/(2,000 hr/yr)= 4.08 tn/ r PM

(4)NMOC Emissions
-Use the default concentration of NMOC(as hexane)from AP42 Table 2.4-2. The default NMOC concentration is 595 ppmv.
-Use Equations(3),(4),&(5)of AP-42,Section 2.4 to determine NMOC emissions.
Molecular weight of hexane= 86.18 g/gmol
LFG consumed= 489,673 MMBtu/yr
Hours of operation= 8,760 hr/yr
HHV of landfill gas= 500 Btu/ft'
Amount of landfill gas consumed=(489,673 MMBtu/yr)/(500 MMBtu/million ft3)= 979.35 x106 ft3 LFG
Eqn(3)
QNMOC=(979.35 x 10*113)*(m3/35.3198 ft)*(595 ppmv/106)= 16,498 m'/yr
Eqn(4)
UMNMOC=(16,498 m3)*[(86.18 g/gmol* I atm)/(8.205E-5 m3-atm/gmol-K*1,000 g/kg*(273+25 K))]_
UMNMOC= 58,149.6 kg
Eqn(5)
CMNMOC=[58,149.6 kg*(I -NCO /100)]+58,I49.6 kg*(NCOL/100)*0 -N(,B/100)]
NCOL=100%since talc is based on actual flow rate to the flare and not an assumed collection rate.
NCNT=99.2% Assume that the flare is capable of reducing NMOCs 99.2%by weight(AP42 Table 2.4-3).
CMNMOC=58,149.6 kg*(I -100/100)]+58,149.6 kg*(100/100)*(1-99.2/100)]= 465.20 kg
CMNMOC=(465.20 kg)*(2.2lb/kg) = 11,023.4 Ib/yr NMOC
CMNMOC=(1,023.4 lb/yr)/(8,760 hr/yr) = 0.12 Ib/hr NMOC
CMNMOC=(1,023.4 lb/yr)/(2,000 lb/tn)= U.SI tn/yr NMOC
(5)VOC Emissions
- Use Note"c"from Table 2.4-2. The default VOC content at non-co-disposal sites is 39%of NMOC by weight(235 ppmv as hexane).
CMva=1,023.4 lb/yr NMOC*0.39= 399.14 lb/yr VOC
CMva=0.12 Ib/hr NMOC*0.39= 0.05 lb/hr VOC
CMva=0.51 tn/yr NMOC*0.39= 0.20 tn/yr VOC f

Eqn(7)
CMso2=1,212 kg S*(NCOU100)*2.0"(98%conversion efficiency of S to S02)
Ncoc=100%since cale is based on actual flow rate to the flare and not an assumed collection rate.
CMso2=1212.48 kg S*(100/100)*2.0"0.98= 2,376A5 kg/yr

-HAPs are calculated in a manner consistent with NMOCs,except that the concentration and molecular weight of the individual HAPs
are substituted into the equations. See Table 3 for a summary of flare HAP emissions.

-Use Equations(3),(4),&(10)from AP-42 Section 2.4 to determine HCl emissions.
HCl concentration= 42.0 ppmv (AP-42,Page 2.4-9)
Molecular weight of chlorine(Cl)= 35.453 g/gmol
HHV of landfill gas= 500 Btu/ft'
LFG consumed= 489,673 MMBtu/yr
Hours of operation= 8,760 hr/yr
Amount of landfill gas consumed=(489,673 MMBtu/yr)/(500 MMBtu/MM 113)= 979.35 x106 ft3 LFG
Eqn(3)
QS= (979.35 x MM 0)*(m3/35.3198 ft3)*(42.0 ppmv C1110^6)= 1,164.59 m3 CI
Eqn(4)
UMCI=(1,164.58 m3)*[(35.453 g/gmol* 1 atm)/(8.205E-5 m3-atm/gmol-K* 1,000 g/kg*(273+25 K))]_
UMci= 1,688.6 kg Cl
Eqn(10)
CMHCI=1,688.6 kg Cl* (NCOU100)* 1.03*(NCNT/100)
NCoL=100%since calc is based on actual flow rate to the flare and not an assumed collection rate.
NcNT=100%Assume the flare is capable of converting 100%of the Cl to HCI.
CMHCI=1,688.6 kg CI*(100/100)*1.03*(100/100)= 1,739.3 kg/yr HCl
CMHC1=(1,739.3 kg)*(2.2 lb/kg) = 3,826.4 Ib/ r HCI
CMHCI=(3,826.4 lb/yr)/(8,760 hr/yr)= 0.44 Ib/hr HCI
CMHCI=(3,826.4 Ib/yr)/(2,000 Ib/tn)= 1.91 to r HCI
