1.0 INTRODUCTION On behalf of our client, North Country Environmental Services, Inc. (NCES), Sanborn, Head & Associates, Inc. (Sanborn Head) prepared this Temporary Permit / Title V Air Permit Application (Application) for the NCES landfill located in Bethlehem, New Hampshire. This Application is intended to serve as the basis for a Temporary Permit and a Title V Permit for the facility. NCES’ Solid Waste Landfill Permit for Stage IV allows NCES to construct and operate capacity to dispose of solid waste that together with Stages I, II, and III of the landfill exceed a design capacity of 2.5 million megagrams of solid waste, the size threshold of applicability under the New Source Performance Standards (NSPS) for Municipal Solid Waste (MSW) landfills contained in 40 Code of Federal Regulations (CFR) Part 60, Subpart WWW. Exceeding the size threshold subjects NCES to reporting requirements under the NSPS, including an initial design capacity report, Non-Methane Organic Compound (NMOC) emission rate reporting, and the requirement to obtain a Title V Operating Permit. NMOC emissions have been demonstrated to be less than the 50 megagrams per year NSPS emission threshold, therefore, NCES is not currently subject to the collection, control, monitoring, and additional reporting requirements of the NSPS. In accordance with Chapter Env-A 1700, Permit Application Forms, of the New Hampshire Code of Administrative Rules (NHCAR), the following information is applicable to the NCES facility and is included herein: • Form ARD-1 in Appendix A; includes facility identification, location, and emission

information; • Forms ARD-2 in Appendix A; includes identification, location, and emission information

for the existing Baker flare operating at the NCES landfill and the proposed Parnel Biogas flare;

• Form ARD-3 in Appendix A; includes information related to fugitive emissions of landfill gas (LFG);

• A citation and description of state and federal air pollution control regulations and permit conditions (See Tables 10-12);

• A description of the facility’s compliance status (See Tables 10-12); and • A list of all equipment and devices located at the source classified as insignificant

sources (See Section 4.3). 2.0 FACILITY INFORMATION 2.1 Site Information

581 Trudeau Road Bethlehem, New Hampshire (See Figure 1, Locus Plan)

2.2 Facility / Application Description

The landfill is located on a 105.15-acre aggregation of land in Bethlehem, New Hampshire. The site is bordered on the west by Trudeau Road, on the north by Muchmore Road, and on the east and south by privately-owned and publicly-ownded forestlands. Prior to NCES’ ownership of the Site, lined and unlined landfills had been operated on the property. NCES purchased the site and placed the contents of the unlined landfill in the lined facility as a condition of developing an expansion to the lined landfill. Once the waste was removed from the unlined landfill, only the lined facility existed at this Site. We understand that waste was initially received in the lined landfill in 1987, and the facility continues to accept waste. The current landfill units (four lined cells; Stages I, II, III, and IV) occupy approximately 36 acres (see Figure 1). Stages I, II, III, and part of the permitted footprint for Stage IV have been constructed and municipal solid waste (MSW) has been placed in each of these landfill units. Stages I through III occupy approximately 31 acres.


An active gas collection system consisting of a network of vertical extraction wells and horizontal gas collection trenches has been installed in the NCES Landfill. In addition, LFG is also collected from several leachate collection pipes and tanks. Centrifugal blowers are used to extract gas from the landfill and deliver the gas to the existing Baker utility flare (existing flare), which is permitted under Temporary Permit TP-0078, dated March 28, 2012. The rated capacity of the existing flare is 52.5 million British thermal units per hour (MMBtu/hr), which is equivalent to combusting 1,750 standard cubic feet per minute (scfm) of LFG at 50 percent (%) methane. Upon approval of this Application, NCES intends to install a second utility flare, manufactured by Parnel Biogas, Inc. (proposed flare). The rated capacity of the proposed flare is 2,850 scfm at 50% methane, which equates to a heat input rating of 85.5 MMBtu/hr. The proposed flare will provide redundant capacity for combustion control of the LFG collected from the active gas collection system. NCES intends to operate the existing flare and the proposed flare both simultaneously and individually. NCES proposes to limit the total heat input of LFG delivered to the combustion devices (existing and proposed flares) to 1,000,000 MMBtu/year (which is equivalent to approximately 114 MMBtu/hr). Upon permit issuance, in order to demonstrate compliance with this operating limit, on a semi-annual basis NCES will estimate the volume of total LFG combusted by the two flares and based on LFG composition data collected at the flare during monthly wellfield monitoring events, estimate the annualized total heat input to the combustion devices. Parnel Biogas, Inc. flare specifications are included as Appendix B. Specifications for the existing flare were previously provided to NHDES. 3.0 LANDFILL GAS GENERATION ESTIMATES To assess a range of potential LFG generation rates, Sanborn Head used the U.S. Environmental Protection Agency’s (USEPA’s) Landfill Gas Emissions Model, Version 3.02 (LandGEM) with historical and projected waste acceptance data and varying input parameters. The analysis evaluated the sensitivity of estimated LFG generation rates to changes in the LandGEM input constants: methane generation rate, k, and methane generation potential, Lo. Eleven sets of LandGEM modeling results were generated based on eleven sets of model parameters (i.e., k and Lo). The eleven sets of model parameters were based on AP-42 defaults, published studies, and site-specific LandGEM calibrations performed previously by Sanborn Head.


Sanborn Head converted LandGEM’s LFG generation rates to LFG collection rates based on the current area weighted average collection efficiency of 86.5% through landfill closure and 95% after closure when the landfill will be entirely capped.1

Based on the actual average LFG collection rates during 2001 through 2011 and the various modeled LFG collection rates, Sanborn Head chose a site-specific methane generation potential for the waste of L0=130 m3/Mg. During 2013, NCES intends to begin leachate recirculation, which typically results in increased LFG generation rates. Therefore, for LFG generation modeling with no leachate recirculation (prior to 2013), the site-specific value for the methane generation rate constant estimated by Sanborn Head was used: k=0.07 yr-1. However, for gas generation modeling with leachate recirculation beginning in 2013, we used the following values for k:

a. k=0.16 yr-1, from the USEPA's September 2006 Report on the Outer Loop Landfill in Louisville, Kentucky; and

b. k=0.3 yr-1, from the USEPA's June 2005 Report on Wet Landfills.

Ultimately, the maximum LFG collection rate (2,507 scfm) was estimated using the median value for gas generation rates predicted by LandGEM using the leachate recirculation methane generation rate values for k for waste placed between 2013 and 2018 and 95% collection efficiency. The projections indicate that the LFG collection rate will peak in the year 2018; the year that the currently permitted landfill is estimated to be filled to capacity. Appendix C includes waste acceptance data used as input to the LandGEM model (Table C-1), LandGEM model results (annual LFG generation rates) (Table C-2), and annual LFG collection rates (Table C-3). 4.0 AIR POLLUTANT EMISSIONS The NHDES classifies air emission sources for various categories by source types and emission thresholds. At the NCES landfill, there are three categories of emission sources as defined by the NHDES. These sources include: air pollutant sources, insignificant sources, and exempt sources. Utility flares are recognized in the NSPS as devices capable of destroying methane and NMOCs during combustion of LFG. The LFG collection and control system flares operate to capture, combust and destroy methane, NMOCs, and reduced sulfur compounds (the Primary Pollutants) in LFG. LFG combustion by the flares will decrease actual emissions of Primary Pollutants from the landfill that would otherwise be emitted in an uncontrolled manner (i.e., fugitively) to the atmosphere. The flares are designed to destroy 98% of the NMOCs and methane in the LFG, as well as to destroy potentially odorous reduced sulfur compounds in the gas.

1 Based on AP-42 guidance, we have assumed that the collection efficiency for the active, intermediate cover, and capped areas of the landfill are 75%, 85%, and 95%(respectively) of the total landfill gas generated.


In addition to acting as a pollution control device for the Primary Pollutants, the flares are also potential sources of Secondary Pollutants. The combustion of LFG in a utility flare results in the emission of air pollutants that are either created by secondary reactions during the combustion process (NOx and sulfur oxides [SOx

]), or are the products of incomplete combustion (CO) (together, the Secondary Pollutants).

The emissions of SOx will depend on the amount of total reduced sulfur (TRS) in the LFG, because most of the TRS will be converted to SOx

. The emissions of the other Secondary Pollutants will depend on the conditions encountered during combustion.

As referenced on Form ARD-1 (Appendix A), Table 1 is a summary of the estimated actual emissions during 2011 from the existing flare (Table 4), fugitive LFG (Table 5), and vehicles / roadways (Table 6) at the NCES landfill. The actual estimated emission rates from the existing flare (Table 4) are based on the average measured flow rate to the flare during 2011, corrected to 50% methane. The actual estimated fugitive emission rates (Table 5) are based on the average measured LFG flow rate to the flare during 2011 and a current area weighted average collection efficiency of 86.5%.2

Therefore, it is assumed that 13.5% of the generated LFG escapes fugitively.

Table 2 is a summary of potential emissions from the existing flare (Table 7), proposed flare (Table 8), fugitive LFG (Table 9), and vehicles / roadways (Table 6). The potential emissions estimate presented in Table 2 is based on the existing and proposed flares operating at their rated capacities and fugitive LFG emissions based on the maximum amount of LFG predicted to be generated by LandGEM (2,639 scfm) and a collection efficiency of 86.5% at full build-out of the landfill shortly before the landfill is capped. Table 3 is a summary of emissions from the existing flare and proposed flare based on the proposed operating limit of 1,000,000 MMBtu/yr (or 114 MMBtu/hr) of heat input to the two flares. 4.1 Emission Factors / LFG Constituent Concentrations

In accordance with the NSPS, Sanborn Head performed sampling to determine the NMOC concentration in LFG at the NCES landfill on May 14, 2009. NMOC sampling and analysis were conducted in general accordance with Tier 2 procedures outlined in the MSW landfill NSPS. The average Tier 2 test results for NMOCs, as hexane3

was 187 parts per million (ppm). We estimated VOC emissions by using a VOC concentration in LFG of approximately 73 ppm, which corresponds to 39% (based on AP-42 guidance) of the NMOC concentration measured during May 2009. Thes values were used to estimate NMOC and VOC flare and fugitive emissions in the attached tables.

Emission factors used to calculate CO, PM, and NOx

2 See footnote no. 1.

, emissions from the flares were based on AP-42 or specifications provided by the flare manufacturer(s).

3 As indicated in Part 60.754 (a)(3) of the MSW NSPS, “The landfill owner or operator must divide the NMOC concentration from Method 25 or 25C of Appendix A of this part by six to convert from CNMOC as carbon to CNMOC as hexane.” Therefore, we divided the NMOC concentration in the laboratory report by six.


The estimate of actual SOx emissions from the existing flare (Tables 1 and 4) is based on the average TRS concentration in LFG from samples collected four times throughout 2011, and submitted to Atmospheric Analysis & Consulting, Inc. (AAC) of Ventura, California for analysis of TRS and natural gas parameters using American Society of Testing and Materials (ASTM) Method D-5504 and D-1945, respectively. The estimate of actual hydrogen sulfide (H2S) emissions from the existing flare and fugitive LFG (Tables 1, 4, and 5) is based on the average H2

S concentration in LFG from the same samples.

The estimate of potential SOx emissions from the existing and proposed flares (Tables 2, 3, 7, and 8) is based on a conservative (high) estimate of TRS concentrations in the future (1,500 ppm at 50% methane); based on an analysis of historic TRS sampling results at the site. The estimate of potential fugitive H2S emissions (Tables 2 and 9) is also based on a conservative (high) estimate of H2

S concentration (1,500 ppm at 50% methane).

With the exception of H2

S, the source of all Hazardous Air Pollutant (HAP) and Regulated Toxic Air Pollutant (RTAP) concentration data is AP-42.

4.2 Roadway / Vehicle Emissions

Particulate matter (PM) is a generic term for a broad class of chemically and physically diverse substances that exist as discrete particles (liquid droplets or solids) over a wide range of sizes. PM10 is particulate matter with an aerodynamic diameter of 10.0 microns or less. Particulate emissions occur whenever vehicles travel over paved or unpaved surfaces such as roads or parking lots. Particulate emissions from roads are due to direct emissions from vehicles in the form of exhaust, brake and tire wear, and re-suspension of loose material on the road surface. In general terms, re-suspended particulate emissions from paved roads originate from, and result in the depletion of, the loose material present on the surface (i.e., the surface loading). In turn, the surface loading is continuously replenished by other sources. At landfill sites, surface loading occurs directly on unpaved roads and is replenished by track out from unpaved roads and staging areas. The amount of PM10 generated by vehicle exhaust, tire and brake wear, and road dust at the landfill was estimated assuming a waste acceptance rate of 540-tons per day (tpd) in NCES’ June 2004 Title V Operating Permit Application using the USEPA’s MOBILE6.2 model following the methodology described in the User’s Guide to MOBILE6.1 (8/03). Similarly, road-related emissions of PM10 were estimated in the 2004 Application using Sections 13.2.1-Paved Roads (12/03) and 13.2.2-Unpaved Roads (12/03) of AP-42. At that time, it was estimated that 12.8 tpy of PM10 would be emitted from vehicles and roadways, assuming a waste acceptance rate of 540 tons/day. For the purposes of this Application, we used the same emissions estimate for vehicles and roadways based on the following assumptions:

• The unpaved road and haul road distances at the Facility have not changed significantly;


• The 2004 PM10 vehicles and roadways emissions estimate was conservative (high) because we did not take into account any mitigation (e.g., road sweeping, water application or other measures to keep the road dust down);

• The number of employee vehicles / trips has not changed significantly; and • The 2004 estimate was based on a waste acceptance scenario of approximately 540

tons/day which is conservative (high) based on current waste acceptance data.4

Actual and potential roadway/vehicle emissions (Tables 6) are estimated to be equivalent. Roadway/vehicle emissions are proportional to the number of vehicles and the vehicle-miles traveled at the Site and NCES is proposing to maintain the current waste acceptance rate (and thus generally consistent vehicle traffic until the landfill is closed). 4.3 Insignificant Sources

Insignificant activities at the NCES facility that meet the criteria set forth in the New Hampshire Code of Administrative Rules, Section Env-609.04 include:

• A space heater located in the facility’s maintenance garage which combusts No. 2 fuel oil and waste oil;

• An emergency generator which combusts diesel fuel; • A space heater in the scale house which combusts kerosene; and • A flare propane-fired pilot gas system.

There are also various tanks located at the NCES facility including:

• A 500-gallon above ground storage tank (AST) used to store waste oil and No. 2 fuel oil located in the maintenance garage;

• A 1,200-gallon mobile tanker truck stores diesel fuel to refuel landfill equipment; • A 275-gallon AST used to store motor oil located in the maintenance garage; • A 275-gallon AST used to store hydraulic oil located in the maintenance garage; • A 275-gallon AST used to store kerosene located adjacent to the scale house; and • A 50-gallon pressurized tank used to store propane gas located near the existing

flare. Emissions from insignificant activities listed above were quantified in the January 2008 Title V Operating Permit Application and are not repeated herein. It should also be noted that a portable crusher may be used on-Site during construction projects. However, NCES does not own a crusher, nor does one routinely reside on-Site. Portable crusher emissions estimates are not included in this Application.

4 Future waste acceptance projections are 140,000 tons of waste per year which equates to approximately

540 tons/day. Therefore, the 2004 PM10 vehicles and roadways emissions estimate is suitable to use for both actual and potential emissions in this Application.


4.4 Exempt Sources

The operations at NCES include activities that are considered exempt activities under Env-A 609.03(c), which include, but are not limited to:

• Office activities; • Interior, exterior, and architectural maintenance activities on the buildings and

grounds; • Maintenance of landfill equipment and hauling company vehicles; • Maintenance of landfill gas recovery facilities; • The use of consumer products for maintenance and other activities; and • The use of mobile or portable equipment, which may be owned by NCES or outside

contractors, including: portable space heaters; portable generators; construction equipment; and mobile or portable equipment to mix, pump, grind, crush, and compact refuse and other materials.

4.5 Greenhouse Gas Emissions

The USEPA signed a final rule on July 1, 2011 that defers for a three-year period the application of the Prevention of Significant Deterioration (PSD) and Title V permitting requirements to biogenic CO2 emissions from bioenergy and other biogenic stationary sources, including CO2 generated in landfills and CO2 from combustion of LFG (i.e., the total amount of CO2 emissions presented in the attached tables). Based on the USEPA's deferral, the greenhouse gas (GHG) emissions estimates presented in the attached tables should exclude CO2. We have presented GHG emissions in units of CO2 equivalents both including and excluding these biogenic CO2

emissions.

Step 2 of the GHG Tailoring Rule (relevant to permitting actions between July 1, 2011 and June 30, 2013) requires that:

• Title V air emissions sources revising or renewing their permits address GHGs and; • Sources that emit or have the potential to emit GHGs at or above 100,000 tpy carbon

dioxide equivalents (CO2eq) and 100 tpy GHGs on a mass basis (excluding biogenic CO2

as described above) be subject to additional GHG permitting requirements.

As such, the facility is required only to address GHGs. For example, addressing GHG emissions includes citation and description of any applicable requirements for GHGs, information pertaining to any associated monitoring and other compliance activities, and any other information considered necessary to determine the applicability of requirements for GHGs. Therefore, GHG emissions estimates have been included in the attached tables for informational purposes only. It is our understanding that GHG emissions estimates will not be used at this time to add additional requirements to NCES’ Temporary Permit or Title V Operating Permit. The GHG emission estimates include flare combustion by-product GHG emissions and flare non-combustion GHG emissions. It should be noted that the LFG collection system at NCES landfill is considered comprehensive and therefore, any LFG


escaping collection cannot reasonably be collected (therefore considered fugitive). Because the existing Title V and PSD permitting programs do not count fugitive emissions when evaluating if a facility is a major source, we intentionally did not include fugitive LFG emissions in the GHG emissions estimates in the attached tables. 5.0 APPLICABLE REQUIREMENTS 5.1 New Hampshire and Federal Regulations

Tables 10 and 11, respectively, list New Hampshire and Federal air pollution control regulations that we evaluated to determine NCES’ compliance status. These tables also include determinations as to whether the regulations are applicable to the NCES facility, compliance status of the NCES facility with respect to the regulations, and the compliance schedule for those aspects of facility operations that require further action. 5.2 Permits

The existing flare is currently permitted under Temporary Permit TP-0078 issued on March 28, 2012. The NCES facility does not have a Title V Air Pollution Control Permit. Table 12 lists the conditions included in the existing Temporary Permit and summarizes the compliance status of each device with respect to the permit conditions. 6.0 AIR POLLUTANT DISPERSION MODELING Air pollutant dispersion modeling will be performed in support of this Application and submitted to NHDES in approximately September 2012. 7.0 COMPLIANCE PLAN Tables 10, 11, and 12 list the compliance status with respect to applicable air regulations and the existing air permit for the NCES facility. We understand that NCES is committed to operate the NCES landfill in compliance with applicable NHDES and Federal regulations. As required by Temporary Permit TP-0078, the facility maintains compliance with Revision No. 2 of the Landfill Gas Collection System, Enhanced Monitoring Protocol and Standard Operating Procedures (EMP/SOP), dated February 1, 2012 and approved by NHDES on March 22, 2012. The EMP/SOP includes procedures and practices followed by NCES and agreed upon by NHDES which allow for best practices in LFG collection and control including sampling procedures and methodologies for testing of LFG composition. NHDES Form ARD-1, in Appendix A, includes the signature of an authorized representative of NCES which signifies his certification of information accuracy contained within this Application.

Mass Flow Delivered to Flares

Baker and Parnel Flare Proposed Permitted Emissions

Notes: 1. RTAPs listed in the US EPA's Compilation of Pollutant Emission Factors (AP-42), Section 2.4, MSW Landfills (dated 11/98), Table 2.4-1 and Table 2.4-2, have been included in emissions estimate. Benzene and toluene data is listed in AP-42 Table

2.4-2. 2. The PM emission factor is from AP-42 Table 2.4-5. The CO and NO2 emission factors for the two flares are the same, based on AP-42 Table 13.5-1 and information provided by Parnel Biogas, Inc. 3. PM, CO, NOx, and SOx are considered combustion by-products of the flare and are not generally present in landfill gas (LFG). 4. NMOC concentration data obtained from Tier 2 sampling conducted on May 14, 2009 by Sanborn, Head & Associates, Inc. VOC concentration is estimated to be 39% of NMOC concentration based on AP-42, Section 2.4, MSW Landfills, Table 2.4-2. 5. The hydrogen sulfide concentration of 1,500 ppm is based on a conservative (high) estimate of Total Reduced Sulfur (TRS) concentrations in the future; based on an analysis of historic TRS sampling results at the site. 6. It is assumed that LFG with 50% methane has a heating value of 500 Btu/ft3. 7. The total LFG heat input to the combustion devices (Baker flare and Parnel flare) is proposed to be limited to 1,000,000 MMBtu/year or approximately 114 MMBtu/hr (which equates to a total LFG collection rate of approximately 3,805 scfm at

50% methane). It should be noted that the estimated total maximum future LFG delivered to both flares is 2,507 cfm at 50% methane (based on the U.S. Environmental Protection Agency's LandGEM Model and a collection effiency of 95%). 8. Carbon dioxide (CO2) is generated in the landfill, and is also generated in the process of methane combustion. The CO2 concentration in landfill gas used in the greenhouse gas emissions estimate (45 percent) is an approximation based on typical

concentrations in landfill gas. 9. According to USEPA, the global warming potential (GWP) of a ton of methane is 21 times greater than a ton of CO2; therefore, a ton of methane is equal to 21 tons of carbon dioxide equivalents (CO2eq). 10. USEPA signed a final rule on July 1, 2011 that defers for a period of three years the application of the Prevention of Significant Deterioration (PSD) and Title V permitting requirements to biogenic CO2 emissions from bioenergy and other biogenic

stationary sources, including CO2 generated in landfills and CO2 from combustion of LFG (i.e., the total amount of CO2 emissions presented here). Based on the USEPA's deferral, the GHG emissions estimate presented here should exclude CO2. We have presented GHG emissions in units of CO2 equivalents both including and excluding these biogenic CO2 emissions.

listed in AP-42 Table 2.4-2. 2. The PM emission factor for the open flare is from AP-42 Table 2.4-5. The CO and NO2 emission factors for the open flare are from AP-42 Table 13.5-1. 3. PM, CO, NOx, and SOx are considered combustion by-products of the flare and are not generally present in landfill gas (LFG). 4.

VOC concentration is estimated to be 39% of NMOC concentration based on AP-42, Section 2.4, MSW

Landfills, Table 2.4-2. 5. The hydrogen sulfide concentration is based upon site-specific data provided by Sanborn Head and Associates, Inc. Landfill gas (LFG) samples for Total Reduced Sulfur (TRS) analysis were collected by Sanborn, Head &

Associates, Inc. (Sanborn Head) four times throughout 2011, and submitted to Atmospheric Analysis & Consulting, Inc. (AAC) of Ventura, California for analysis of TRS and natural gas parameters using American Society of Testing and Materials (ASTM) Method D-5504 and D-1945, respectively.

6. It is assumed that LFG with 50% methane has a heating value of 500 Btu/ft3 7. The average LFG flow rate to the flare is based on monthly flare flow data during 2011 (1,378 scfm; which has been corrected to 50 percent methane based on the methane content of the LFG at the flares measured on the

corresponding days). 8. Carbon dioxide (CO2) is generated in the landfill, and is also generated in the process of methane combustion. The CO2 concentration in landfill gas used in the greenhouse gas emissions estimate (45 percent) is an

approximation based on typical concentrations in landfill gas. 9. According to USEPA, the global warming potential (GWP) of a ton of methane is 21 times greater than a ton of CO2; therefore, a ton of methane is equal to 21 tons of carbon dioxide equivalents (CO2eq). 10.

Based on the USEPA's deferral, the GHG emissions estimate presented here should exclude CO2. We have presented GHG emissions in units of CO2 equivalents both including and excluding these biogenic CO2 emissions.

Notes: 1. RTAPs listed in the US EPA's Compilation of Pollutant Emission Factors (AP-42), Section 2.4, MSW Landfills (dated 11/98), Table 2.4-1 and Table 2.4-2, have

been included in emissions estimate. Benzene and toluene data is listed in AP-42 Table 2.4-2. 2. NMOC concentration data obtained from Tier 2 sampling conducted on May 14, 2009 by Sanborn, Head & Associates, Inc. VOC concentration is estimated to be

39% of NMOC concentration based on AP-42, Section 2.4, MSW Landfills, Table 2.4-2. 3. The hydrogen sulfide concentration is based upon site-specific data provided by Sanborn Head and Associates, Inc. Landfill gas (LFG) samples for Total

Reduced Sulfur (TRS) analysis were collected by Sanborn, Head & Associates, Inc. (Sanborn Head) four times throughout 2011, and submitted to Atmospheric Analysis & Consulting, Inc. (AAC) of Ventura, California for analysis of TRS and natural gas parameters using American Society of Testing and Materials (ASTM) Method D-5504 and D-1945, respectively.

4. It is assumed that LFG with 50% methane has a heating value of 500 Btu/ft3. 5. The approximate LFG generation rate is based on the measured LFG flow rate to the flare during 2011 and a current area weighted average collection

efficiency of 86.5%. It is assumed that the approximate LFG fugitive emissions is the difference between the LFG generation rate and LFG flow rate to the flares.

Notes: 1. RTAPs listed in the US EPA's Compilation of Pollutant Emission Factors (AP-42), Section 2.4, MSW Landfills (dated 11/98), Table 2.4-1 and Table 2.4-2, have been included in emissions estimate. Benzene and toluene data is listed in AP-42

Table 2.4-2. 2. The PM emission factor for the open flare is from AP-42 Table 2.4-5. The CO and NO2 emission factors for the open flare are from AP-42 Table 13.5-1. 3. PM, CO, NOx, and SOx are considered combustion by-products of the flare and are not generally present in landfill gas (LFG). 4. NMOC concentration data obtained from Tier 2 sampling conducted on May 14, 2009 by Sanborn, Head & Associates, Inc. VOC concentration is estimated to be 39% of NMOC concentration based on AP-42, Section 2.4, MSW Landfills, Table

2.4-2. 5. The hydrogen sulfide concentration of 1,500 ppm is based on a conservative (high) estimate of Total Reduced Sulfur (TRS) concentrations in the future; based on an analysis of historic TRS sampling results at the site. 6. It is assumed that LFG with 50% methane has a heating value of 500 Btu/ft3. 7. The maximum LFG flow rate to the open flare is 1,750 cfm, based on a maximum rated heat capacity of 52.5 MMBtu/hr. 8. Carbon dioxide (CO2) is generated in the landfill, and is also generated in the process of methane combustion. The CO2 concentration in landfill gas used in the greenhouse gas emissions estimate (45 percent) is an approximation based on

typical concentrations in landfill gas. 9. According to USEPA, the global warming potential (GWP) of a ton of methane is 21 times greater than a ton of CO2; therefore, a ton of methane is equal to 21 tons of carbon dioxide equivalents (CO2eq). 10. USEPA signed a final rule on July 1, 2011 that defers for a period of three years the application of the Prevention of Significant Deterioration (PSD) and Title V permitting requirements to biogenic CO2 emissions from bioenergy and other

biogenic stationary sources, including CO2 generated in landfills and CO2 from combustion of LFG (i.e., the total amount of CO2 emissions presented here). Based on the USEPA's deferral, the GHG emissions estimate presented here should exclude CO2. We have presented GHG emissions in units of CO2 equivalents both including and excluding these biogenic CO2 emissions.

effiency of 95% when the entire landfill is capped). 6. For the purposes of estimating the potential fugitive LFG emissions, this table uses the maximum amount of LFG predicted to be generated (2,639 scfm) (based on

LandGEM modeling) and the estimated area weighted average capture efficiency shortly before the landfill is capped at full buildout (86.5% collection efficiency).

Notes: 1. Megagrams (Mg) = tons x 0.907185

2. Annual waste acceptance rate data for 1976 through 1995 is from a July 2, 1996 letter from Sanborn Head to NHDES regarding landfill gas emissions

modeling. This data was originally provided by NCES.

3. Annual waste acceptance data for 1996 through 2011 are from annual reports prepared by NCES for NHDES.

4. An unlined landfill was operated at the site from 1976 to 1987. The content of the unlined landfill was subsequently placed in the lined landfill. To estimate current and future landfill gas generation rates for the relocated unlined landfill waste, the relocated waste was input to the model as if it had been received in the lined landfill during the same year it was received in the unlined landfill.

5. Year of landfill closure is based on the total remaining permitted capacity of Stages I, II, III, and IV (974,735 tons as of 1/1/11, provided to Sanborn Head by Joe Gay on September 29, 2011) and an assumed future waste acceptance rate of 140,000 short tons per year until the landfill is closed.

Generation Rate Summary

Notes: 1. Landfill gas (LFG) generation rates were estimated with the USEPA's "Landfill Gas Emissions Model (LandGEM), Version 3.02," using historical and

projected waste acceptance, and the site-specific methane generation potential of the waste estimated by Sanborn Head: L 0=130 m3/Mg. For gas generation modeling with no leachate recirculation, the site-specific value for the methane generation rate constant estimate d by Sanborn Head was used: k=0.07 yr-1.

2. For gas generation modeling with leachate recirculation beginning in 2013, we used the following values for k: a. k=0.16 yr-1, from the USEPA's September 2006 Report on the Outer Loop Landfill in Louisville, Kentucky; and b. k=0.3 yr-1, from the USEPA's June 2005 Report on Wet Landfills.

PURPOSE: The purpose of these sample calculations is to present the methods used to estimate emission rates for the North Country Environmental Services, Inc (NCES) Landfill. GIVEN:

Methane (CH4) Concentration = 50% by volume LFG Heat Content at 50% CH4 = 500 Btu/scf (higher heating value [HHV]) Molar Volume of Gas = 24.45 liters per mole at standard conditions (298 K, 760 mmHg) TRS concentration = 1,089 ppmv (based on site-specific sampling during 2011)

LFG Flow Rate to the Baker Flare during 2011 at 50% CH4 = 1,378 scfm

CALCULATION: Combustion by-product emissions (CO, NOx, SO2, and PM):

1. Sulfur dioxide (SO2) emissions are based on LFG flow rate and the concentration of total reduced sulfur (TRS), which is 1,089 ppmv (based on site-specific sampling) for the Baker flare. SO2 for the Baker flare at the current actual flow (1,378 scfm) is used as an example.

NMOCs, VOCs, HAPs, and RTAPs Emissions – constituents of LFG, reduced via flare combustion (98% destruction efficiency): Non methane organic compounds (NMOCs), volatile organic compounds (VOCs), hazardous air pollutants (HAPs), and regulated toxic air pollutant (RTAPs) emissions are based on concentrations of compounds in LFG.

http://www.sanbornhead.com/�




From the list of HAPs / RTAPs in LFG (from AP-42), hexane is used as an example for estimating emission rates. The concentration for hexane from AP-42 is 6.57 ppmv (i.e., 6.57 moles of hexane per million moles of LFG). The estimated hexane emission rate from the Baker flare (assume 98% control efficiency) for the current actual flow (1,378 scfm) =

NMOCs, VOCs, HAPs, and RTAPs – Fugitive Emissions:

Total LFG Generated = LFG Collected + Fugitive LFG The approximate LFG generation rate is based on the measured LFG flow rate to the flare during 2011 and a current area weighted average collection efficiency estimated to be 86.5 percent. Assuming that 1,398 scfm was collected at an approximate 86.5 percent collection efficiency, then 1,593 scfm of LFG would be generated in the landfill and 215 scfm would be emitted fugitively. Hexane is used as an example. The Estimated Hexane Fugitive Emission Rate =

Greenhouse Gas Emissions:

Greenhouse Gas (GHG) emissions are from methane (CH4) and carbon dioxide (CO2) generated in the landfill. Methane is converted to CO2 during combustion. LFG generated in the landfill is typically 50% CH4 and 45% CO2

. GHG emissions are calculated for the actual current flow of 1,378 scfm.
