The emissions inventory presented herein is the basis for the emissions values reported in the DAQ Air Emissions Reporting Online (AERO)system and CY2018 Inventory Certification, as provided in Appendix A. The emission sources identified were based on discussions and correspondence with Landfill staff, SCS Engineers' (SCS) knowledge of the site, a review of existing permit, compliance reports, and other information provided by the Landfill staff. Facility-wide emissions at the Landfill were provided in Table 1 below. Facility-wide emissions including speciated HAPs were provided in the detailed emission calculations in Appendix B. Emissions for each source were further detailed in the remaining sections of this report. This document is submitted in conjunction with the online reporting using AERO system.

Emissions from Welding Operations and Diesel Engines are"carried forward"from the prior reporting year as allowed by the DEQ,DAQ AERO reporting system 2.0 UNCOLLECTED 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 its fugitive emissions. East Carolina Environmental Landfill www.scsengineers.com 2018 Emissions Inventory Page 1 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 Lo and k used in the LanclGEM 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, Lo, 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-' 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 2018 was approximately 10.36 million Mg, or 11.42 million tons. The LandGEM estimated that the methane generation rate for CY2018 was approximately 28.39 million cubic meters, or approximately 1.003 billion cubic feet. Assuming that the methane content in the LFG is 50 percent, the volume of LFG generated in CY2018 was estimated to be 3,815 cubic feet per minute (ft3/min). LandGEM input and output are provided on page 1 of the spreadsheets included with this submittal as Appendix B. 2.1 NON-METHANE ORGANIC COMPOUND (NMOC) EMISSIONS NMOC generation from the Landfill was calculated using LanclGEM. Model parameters were similar to the values noted above. LanclGEM estimated that the NMOC generation rate for CY2018 is 121.10 Mg, or 133.49 tons (See page 2 of the spreadsheets provided in the Appendix B). The Landfill operates a gas collection and control system (GCCS)to capture LFG and route it to control flares. Seventy-five percent of the LFG is assumed to be captured; therefore, 25 percent of the NMOC generated is assumed to have been emitted as fugitive. Thus,the fugitive NMOC emission rate for calendar year 2018 is estimated to be 33.37 tons. 2.2 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 g and NMOC generation rates were extracted from the LanclGEM output and represent the emissions from the Landfill during CY2018. 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 CY2018 is 52.06 tons/yr. The fugitive VOC emission rate is determined in 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 CY2018 is 13.02 tons, as shown in Table 2 below. East Carolina Environmental Landfill www.scsenaineers.com 2018 Emissions Inventory Page 2 Table 2.

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). 3 Q M = 2.0xQ CP P yr Cho lob where: Qp = Pollutant generation rate (m3/yr) Qcha = Methane generation rate (m3/yr)from the LandGEM Cp = Pollutant concentration in LFG (ppmv) 2.0 = Multiplication factor(assumes LFG is 50 percent methane, and the balance is carbon dioxide, nitrogen, oxygen and other trace gases) MP (tons/yr) = QP ((MWP(g/gmol))(1 atm)) ton C (8.205x10-5 r m3 —atm r1000g1 (273+TK 1907.185 kg] � gmol—K/I JI\ kg J � where: Mp = Pollutant mass generation rate MWp = Molecular weight of pollutant(g/gmole) T = Temperature of LFG (OC) (Standard temp of 25 degrees Celsius) 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. Since site-specific data was not available, default concentration values from the Waste Industry Air Coalition Report dated January 2001 were used, as shown on page 4 of the spreadsheets in the detailed emission calculations (Appendix B). 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 CY2018 was calculated to be 4.01 tons. East Carolina Environmental Landfill www.scsenaineers.com 2018 Emissions Inventory Page 3 3.0 LANDFILL GAS FLARE EMISSIONS The landfill operates two flares as a landfill gas control devices, each with a design capacity of 3,000 scfm. The emission factors and annual emissions associated with each flare, designated as CD- Flarel and CD-Flare2, are summarized in Table 3 below. Table 3.

These estimates assume a 75%LFG collection efficiency for the active landfill gas collection system. Control efficiency obtained from AP-42,Table 2.4-5. 5 S02 emissions are calculated per AP-42,Section 2.4.4;H2S Concentration from WIAC-2001(as noted on detailed calculation sheets). East Carolina Environmental Landfill www.scsengineers.com 2018 Emissions Inventory Page 4 4.0 INSIGNIFICANT ACTIVITIES 4.1 DIESEL ENGINES FOR MISCELLANEOUS SUPPORT (IES-04) The Landfill's permit includes an insignificant activity listing for "Diesel Engines for Miscellaneous Landfill Support" with the emission source ID IES-04. Emissions from this source were "carried forward" as allowed in the Division's AERO reporting system, and are therefore represented as reported in the previous reporting period. 4.2 WELDING OPERATIONS (IES-05) The Landfill's permit also includes an insignificant activity listing for "Welding Operations" with the emission source ID IES-05. Emissions from the Landfill's welding operations were "carried forward" as allowed in the Division's AERO reporting system and are therefore identical to the previous reporting period. As reported in previous years, emissions of manganese remained at 101 pounds for calendar year 2018. This is reported as HAPs/TAPS of 5.05E-02 tons per year for the welding operations. 4.3 DIESEL STORAGE TANK (IES-06) The Landfill's permit includes an insignificant activity with description as "Diesel Storage Tank" (IES- 06). Diesel fuel tank was used at the site during CY2018. The emissions from the diesel storage tank were estimated for CY2018 using the U.S. EPA's TANKS 4.0.9d software. NMOC emissions were conservatively estimated to be equal to VOC emissions for diesel tank as shown in Table 1. VOC emissions from diesel storage tank were provided in Table 4 below and emission calculation sheet was included in Appendix B. Table 4.

Total HAP volatilization and NMOC emissions are conservatively estimated to equal VOC emissions. 4.4 LEACHATE STORAGE TANKS (IES-07) The Landfill operates two (2) leachate storage tanks, with emission source ID IES-07 on the insignificant activities list in the permit. These tanks are used to store collected leachate and condensate from the Landfill prior to disposal at an offsite wastewater treatment system. The throughput of leachate in calendar year 2018 was as shown below. For purposes of this air emissions inventory,throughput was allotted equally to both leachate storage tanks. NMOC emissions were conservatively estimated to be equal to VOC emissions for leachate tanks as shown in Table 5. Estimated VOCs emissions were provided in Table 5 below and detailed emission calculations were included in Appendix B.
