2. Based on assumption that 50% of landfill gas is methane

4. Emissions calculated as follows:

PM/PM10/PM2.5 (lb/hr) = Emission Factor (lb/106 dscf methane) * Methane Gas Rate (ft 3/min) * 60 min/hr * 1/1,000,000

NOx/CO/CO2/CH4/N2O (lb/hr) = Emission Factor (lb/MMBtu) * Flare Heat Rating (MMBtu/hr)

CO2e (lb/hr) = CO2 (lb/hr) + CH4 (lb/hr) * 25 + N2O (lb/hr) * 298

SO2/NMOC/VOC/Total HAPs (lb/hr) = (Emissions (tons/yr) * 2,000 lb/ton) / Annual Operation (hr/yr)


Emissions (tons/yr) = Emissions (lb/hr) * Annual Operation (hr/yr) * 1 ton/2,000 lb

NMOC (tons/yr) = Emissions from Balefill (tons/yr) + Emissions from Landfill (tons/yr)

Emissions from Balefill (tons/yr) = 4.85 tons/yr * Collection Efficiency (0.80) * (1 - Control Efficiency (0.98))

Emissions from Landfill (tons/yr) = 5.28 tons/yr * Collection Efficiency (0.70) * (1 - Control Efficiency (0.98))

VOC/Total HAPs emissions calculated using same methodology as NMOC. Values for calculations are as follows:

Balefill VOC = 6.72 tons/yr

Landfill VOC = 7.31 tons/yr

Balefill HAPs = 4.45 tons/yr

Landfill HAPs = 4.85 tons/yr

SO2 emissions calculated based on AP-42, Chapter 2.4 (Nov. 1998), Equations 3, 4, and 7. Input parameters for equations are as follows:

Balefill QCH4 = 4.62E+06 m3/yr

Landfill QCH4 = 5.03E+06 m3/yr

Balefill/Landfill CP = 46.9 ppmv

Balefill/Landfill MWP = 32 g/gmol

Temperature = 298 K


Emissions (tonnes/yr) = Emissions (tons/yr) * 0.907 tonne/ton

First-Order Decomposition Rate Equation:

Where,QCH4 = annual methane generation in the year of the calculation (m 3 /year )i = 1-year time increment Mi = mass of waste accepted in the ith year (Mg ) n = (year of the calculation) - (initial year of waste acceptance)j = 0.1-year time incrementk = methane generation rate (year -1 )Lo = potential methane generation capacity (m 3 /Mg )

About LandGEM:

Friday, September 15, 2017

LandGEM is based on a first-order decomposition rate equation for quantifying emissions from the decomposition of landfilled waste in municipal solid waste (MSW) landfills. The software provides a relatively simple approach to estimating landfill gas emissions. Model defaults are based on empirical data from U.S. landfills. Field test data can also be used in place of model defaults when available. Further guidance on EPA test methods, Clean Air Act (CAA) regulations, and other guidance regarding landfill gas emissions and control technology requirements can be found at http://www.epa.gov/ttnatw01/landfill/landflpg.html.

Description/Comments:

tij = age of the jth section of waste mass Mi accepted in the ith year (decimal years , e.g., 3.2 years)

LandGEM is considered a screening tool — the better the input data, the better the estimates. Often, there are limitations with the available data regarding waste quantity and composition, variation in design and operating practices over time, and changes occurring over time that impact the emissions potential. Changes to landfill operation, such as operating under wet conditions through leachate recirculation or other liquid additions, will result in generating more gas at a faster rate. Defaults for estimating emissions for this type of operation are being developed to include in LandGEM along with defaults for convential landfills (no leachate or liquid additions) for developing emission inventories and determining CAA applicability. Refer to the Web site identified above for future updates.

About LandGEM:

Friday, September 15, 2017

LandGEM is based on a first-order decomposition rate equation for quantifying emissions from the decomposition of landfilled waste in municipal solid waste (MSW) landfills. The software provides a relatively simple approach to estimating landfill gas emissions. Model defaults are based on empirical data from U.S. landfills. Field test data can also be used in place of model defaults when available. Further guidance on EPA test methods, Clean Air Act (CAA) regulations, and other guidance regarding landfill gas emissions and control technology requirements can be found at http://www.epa.gov/ttnatw01/landfill/landflpg.html.

Description/Comments:

tij = age of the jth section of waste mass Mi accepted in the ith year (decimal years , e.g., 3.2 years)

LandGEM is considered a screening tool — the better the input data, the better the estimates. Often, there are limitations with the available data regarding waste quantity and composition, variation in design and operating practices over time, and changes occurring over time that impact the emissions potential. Changes to landfill operation, such as operating under wet conditions through leachate recirculation or other liquid additions, will result in generating more gas at a faster rate. Defaults for estimating emissions for this type of operation are being developed to include in LandGEM along with defaults for convential landfills (no leachate or liquid additions) for developing emission inventories and determining CAA applicability. Refer to the Web site identified above for future updates.

Landfill disposal of municipal solid waste represents one of the largest anthropogenic global 41

methane emission sources1, and recent policy approaches have targeted significant reductions of 42

these emissions to combat climate change in the U.S.2 The efficacy of active gas collection 43

systems in the U.S. was examined by analyzing performance data, including fire occurrence, 44

from more than 850 landfills. A generalized linear model showed that the operating status of a 45

landfill – open and actively receiving waste or closed – was the most significant predictor of 46

collection system performance. Gas collection systems at closed landfills were statistically 47

significantly more efficient (p<0.001) and on average 17 percentage points more efficient than 48

those at open landfills, but open landfills were found to represent 91 percent of all landfill 49

methane emissions. These results demonstrate the clear need to target open landfills to achieve 50

significant near-term methane emission reductions. This observation is underscored by landfill 51

disposal rates in the U.S. significantly exceeding previously-reported national estimates, with 52

this study reporting 262 million tonnes in year 2012 compared to 122 million tonnes in 2012 as 53

estimated by the U.S. Environmental Protection Agency3. 54

The decomposition of municipal waste in landfills is recognized as one of the largest sources 55

of global anthropogenic methane emissions1. Landfills represent the third-largest anthropogenic 56

source of methane in the U.S., comprising approximately 18% of domestic emissions4. As such, 57

the capture and combustion of landfill methane has been identified as a critical and viable near-58

term strategy for greenhouse gas (GHG) reductions associated with the waste sector5 in light of 59

the cost and complexity of implementing wide-scale recycling and waste reduction efforts5. This 60

is a particularly relevant strategy in lower and lower-middle income developing nations where 61

waste generation is expected to increase 185% and 158%, respectively, over current rates by 62

20256. 63

3

Although the U.S. and many E.U. nations have required active landfill gas (LFG) capture for 64

more than a decade7,8, extensive data demonstrating the efficacy of these systems are limited. To 65

fill this important gap, a new dataset with more than 1,200 municipal solid waste landfills, both 66

open and closed, resulting from recently-promulgated U.S. Greenhouse Gas Reporting Rule9, 10 67

was analyzed. The GHG reporting program requires municipal landfills that emit more than 68

25,000 tonnes of carbon dioxide equivalents to electronically report a substantial amount of 69

operating data to the U.S. Environmental Protection Agency (U.S. EPA) annually, including: 70

measured waste acceptance rates, locational data, projected disposal lifetime, and operational 71

data for active gas collection systems (e.g., total operational hours, collected methane content)11, 72

if present. In addition, the GHG reporting rule sets out uniform procedures stipulating how sites 73

must collect, validate, and report these data. 74

Our analysis of this dataset revealed that the total amount of municipal waste disposed in the 75

U.S. was 262 million tonnes in 2012, 115% greater than the U.S. EPA disposal estimate for year 76

2012 (122 million tonnes) which used a materials flow analysis (top-down) approach3 and 77

exceeds the World Bank’s projected municipal waste generation rate for the U.S. in 20256 of 256 78

million tonnes by about 4% (Figure 1). Previously-published survey estimates suggested that the 79

U.S. EPA disposal estimate was low12, but the facility-level nature of our estimate combined 80

with the embedded quality assurance checks makes our estimate the most accurate for the U.S. to 81

date. Since our estimate captures disposal at facilities subject to the GHG Reporting Rule, the 82

quantities in Figure 1 are likely underestimates since smaller landfills are not required to report. 83

We estimated that an additional 10 million to 36 million tonnes of waste were disposed of in 84

2011 (see Supplementary Information). The differences in our estimate from the published top-85

4

down estimates likely stem from errors introduced in top-down methods associated with 86

assumptions regarding waste generation factors for different economic indicators. 87

Together, this larger disposal quantity, which also showed an average disposal rate increase 88

of 0.3% per annum (see Supplementary Information), along with our estimated trend of 89

increasing landfill disposal capacity – an annual increase of 2.7 years from 2010 – 2013 was 90

added in the U.S., and a median of 34 years of available disposal capacity at each landfill (n=413 91

sites) provides a strong near-term indication of continued heavy reliance on landfills as a 92

municipal waste management method in the U.S. Thus, based on the growth in disposal rates and 93

indications of continued reliance on landfilling as a waste management method, capturing LFG 94

generated and reducing these emissions must be a target to meet stated reduction goals in the 95

waste sector. 96

LFG collection system efficiency, which generally reflects the amount of LFG collected 97

relative to the amount generated, was computed within the U.S. EPA GHG reporting program 98

data set based on facility-provided information on the areal coverage of LFG collection 99

infrastructure and the type of cover material (e.g., thin soil layer, thicker clay layer, or synthetic 100

membrane). This methodology was adopted by the U.S. EPA during the development of the 101

GHG Reporting Rule to reflect best available data on efficiency of LFG collection systems 102

measured at several operating landfills13, 14. Although this approach may not provide the 103

accuracy of direct site measurements15, it is useful for understanding the degree of LFG 104

collection system infrastructure deployment at a large population of sites spanning multiple site 105

sizes and climates. 106

A generalized linear model was developed to examine the factors contributing to differences 107

between LFG collection efficiency at each site (see SI for more discussion of the model) and the 108

5

most critical differentiating factor was whether the landfill was open or closed. A comparison of 109

the gas collection efficiency for open and closed landfills shows the efficiency at closed landfills 110

is 17 percentage points greater than open landfills (Figure 2). Year-by-year comparisons 111

revealed statistically significantly greater LFG collection efficiency at closed landfills for all four 112

reporting years analyzed (p < 0.001). The LFG collection efficiencies at open sites were found 113

to be independent of waste acceptance rate (see Figure SI-7), suggesting that challenges to 114

collecting LFG exist at all open landfills, not just larger (or smaller) ones. The disparity in 115

efficiencies between open and closed sites reflects the fact that open landfills have areas that lack 116

a low-permeability barrier layer, which is often installed when the landfill reaches its capacity 117

and is reflected in efficiency parameters selected by each site when reporting data to the U.S. 118

EPA. 119

The gas collection efficiency at landfills that recirculate leachate, which is the practice of 120

deliberately adding liquids to the waste to accelerate waste decomposition as a potentially more 121

sustainable method of landfilling16, indicates that landfills that do not recirculate leachate have a 122

statistically significantly greater (p<0.05) LFG collection efficiency of 4%. This suggests that 123

the deployment of LFG collection infrastructure at sites recirculating liquid is limited relative to 124

those sites not recirculating liquids. 125

In light of the disparity in LFG collection efficiency observed between open and closed 126

landfills, the methane emissions from open and closed sites were analyzed to identify whether 127

similar trends existed. Methane emissions are computed based on a combination of measured 128

data and modeled data at each site. This analysis showed that 91.0% ±0.5% of all methane 129

emissions by mass are from open landfills based on data from 2010 through 2013. The 130

measured methane content of collected gas at closed and open landfills was also compared. The 131

6

results showed that the methane content collected at open landfills was richer (48.5%) compared 132

to that collected at closed landfills (41.1%), with an average difference of 6.2% ±1.1% and year-133

by-year comparisons showed statistically significantly greater methane content at open landfills 134

in each of the four years analyzed (p < 0.001). 135

This comparison shows that the collected methane content is greater at open landfills but the 136

efficiency of gas collection systems is substantially less at open landfills. These results, coupled 137

with the disposal amounts and growth trends, further demonstrate that near-term efforts to reduce 138

methane emissions must focus on implementing improved technologies and collection 139

approaches at open landfills. 140

A challenge to improving gas collection at landfills is the potential for aggressive gas 141

collection practices to contribute to the formation or sustenance of fires or pyrolysis-like 142

reactions limiting the effectiveness of gas collection and potentially releasing other harmful 143

compounds into the atmosphere17, 18, 19. This is of particular concern at open landfills since final 144

capping systems, which are normally installed when a landfill closes, are typically not present18, 145

20, 21, 22, 23. Fires and heat-generating reactions are often initiated or exacerbated through the 146

introduction of air into the waste mass, creating exothermic decomposition reactions and 147

potentially explosive conditions21. 148

Recently, large-scale, multi-year subsurface exothermic events have occurred at landfills in 149

the U.S., and the introduction of air from gas collection systems has been identified as a 150

contributor24, which has also been observed in the literature as a contributing factor21, 22, 23. 151

Although mechanisms of landfill exothermic events or fires have been explored in the literature, 152

an accounting of the frequency of fires in the U.S. along with their presence at sites with gas 153

collection has not been explored. Based on fire incident reporting data for municipal landfills in 154

7

the U.S. from the Federal Emergency Management Agency9, approximately 839 unique landfill 155

fire incidents were estimated to occur in the U.S. annually from 2004-2010, and more than 25% 156

of these incidents were repeated incidents at the same site (Figure 3). Details regarding the 157

precise cause and magnitude of each fire were not available, but the number of fires occurring 158

annually and the frequency of occurrence at a given site supports observations that landfill fires 159

are difficult to fully extinguish21. 160

To examine the occurrence of fires at landfill sites with gas collection systems, locational 161

information from each site in the fire incident data set were matched to landfills that are subject 162

to the Greenhouse Gas Reporting Rule. Out of 869 landfills with an active gas collection system 163

in 2010, 402 or 46% had at least one fire incident between 2004 and 2010 (Figure 4). Of those 164

sites, 151 had more than one reported fire incident during this 7-year span. These results suggest 165

that fires are about as likely to occur at sites with gas collection as those without, and about 17% 166

of the sites with gas collection experienced multiple incidents. Although a causal relationship 167

based on these data cannot be inferred, the data shows that the common occurrence of fires at 168

landfills necessitates planning for these conditions when contemplating new approaches to 169

enhance LFG collection, regardless of whether a site is initiating LFG collection or already has 170

an established LFG collection system. 171

The significant under-prediction of waste disposal quantities when comparing the new U.S. 172

disposal figure with the U.S. EPA’s previous figure and the World Bank estimate underscores 173

the limitations of top-down waste generation estimates and could suggest that similar estimates 174

in other developed and developing nations are low25. A high reliance on landfilling has been 175

observed in the E.U. and in developing nations, similar to the U.S. In 2010, the majority of E.U. 176

countries landfilled more than 50 percent of the generated municipal waste, despite long-177

8

standing policies to divert waste from landfills such as the 1999 Landfill Directive and the 2008 178

Waste Framework Directive26. The World Bank projects that the generation rate of municipal 179

waste will increase in nearly all parts of the world, with the largest increases occurring in low 180

income countries, which are expected to double waste generation rates over 2010 levels by the 181

year 20256. The collective, consistent global trend towards steady or perhaps increasing rates of 182

landfilling clearly demonstrate that the waste sector warrants additional scrutiny to identify GHG 183

emission reduction opportunities at landfills. 184

Improving the collection of LFG at open landfills must be a target for policy makers, 185

researchers, and practitioners to achieve near-term GHG emission reductions in the waste sector. 186

New approaches to enhance LFG collection must acknowledge the common occurrence of 187

landfill fires, which were found to occur about as equally likely at landfills with gas collection as 188

those without based on seven years of fire incident data in the U.S. Given that U.S. landfills 189

have required access control for many years27, the issue of fires could be of greater concern in 190

nations that may lack such rules, since illicit dumping of burning or smoldering materials is also 191

a common cause of landfill fires21. 192

Technological approaches to allow for LFG collection earlier in a landfill’s life, combined 193

with regulatory balancing to maximize LFG capture from open landfills while avoiding 194

unintended consequences related to the formation of or contribution to fires, represents an 195

approach that demands further consideration. Bottom-up design of integrated gas collection 196

systems with traditional liquid collection systems at landfills and the use of temporary, low-197

permeability covers show promise as technological approaches to mitigate methane emissions 198

from open landfills28. While efforts to promote sustainable waste and materials management 199

approaches such as waste reduction, composting, and recycling in developed and developing 200

9

nations must be bolstered, the trends clearly show landfilling as a major component of waste 201

management for the coming decades. Thus, as the municipal waste generation rates continues to 202

grow, policy approaches in developed and developing nations must provide flexibility to allow 203

for innovative implementation of new technologies to enable the greatest level of methane 204

reductions from landfills. 205

Methods 258

US EPA Greenhouse Gas Reporting Data 259

Multiple queries were made through the U.S. EPA’s Greenhouse Gas Reporting Tool website 260

(http://www.epa.gov/enviro/facts/ghg/customized.html) to source the municipal waste disposal 261

quantity, LFG emissions, and LFG collection system performance data and metadata for 262

reporting years 2010, 2011, 2012, and 2013. Every reporting landfill has a unique identification 263

number, so data from the multiple queries were concatenated to develop a complete disposal and 264

emissions profile for every open and closed landfill subject to the reporting rule. The total 265

annual disposal quantity was calculated by summing the individually-reported disposal quantities 266

for every site in each reporting year. A generalized linear model was developed to identify 267

significant predictors of LFG collection efficiency, including site operating status (open and 268

http://www.epa.gov/enviro/facts/ghg/customized.html

13

actively receiving waste or closed), total methane generation, surface area containing waste, total 269

landfill disposal capacity, number of gas collection wells installed, and measured methane 270

concentration. Landfill operating status (open or closed) was found to be a significant (p<0.05) 271

predictor with limited residuals and no interaction with the variables that comprise the 272

calculation of LFG collection efficiency. LFG collection efficiencies were analyzed by first 273

grouping open and closed landfills separately. The mean and 95% confidence interval of the 274

mean collection efficiency were calculated in GraphPad Prism 6 (La Jolla, CA, USA). Statistical 275

significance of LFG collection efficiency differences comparing open and closed landfills was 276

calculated using two-sample t-tests in Minitab statistical software (State College, PA, USA). In 277

similar fashion, the significance of recirculating leachate at landfills on LFG collection 278

efficiency was examined by conducting two-sample t-tests comparing sites that do and do not 279

recirculate leachate frequently. 280

Methane emissions were calculated based on a combination of data measured at each facility 281

and modeled data – details of the equations used to determine methane emissions are presented 282

in the SI. Briefly, the emissions are computed based on the amount of methane generated 283

modeled), the quantity of LFG collected (measured), the methane content of collected gas 284

(measured), and the LFG collection efficiency (described previously). Although some 285

uncertainty can be introduced when modeling LFG generation, the GHG Reporting Rule permits 286

each facility to tailor LFG generation estimates based on the specific nature of the waste 287

materials disposed, if known, which results in greater model accuracy29. 288

U.S. National Fire Incident Reporting System, Reported Fire Incidents at Municipal Landfills 289

U.S. fire incident data were extracted from electronic databases provided by the National Fire 290

Incident Reporting System (NFIRS), which reflects approximately 75% of all fire incidents in 291

14

the U.S. and represents fires electronically reported by fire departments across the U.S. Separate 292

databases were provided to us by NFIRS for each year from 2004 through 2010. These data 293

were compared to data from the U.S. EPA’s Greenhouse Gas Reporting Data for year 2010. 294

Incidents specific to landfill fires were extracted from each year of the NFIRS data by isolating 295

by incident type for “sanitary landfills” (Code 152 in the database). Duplicate entries reflecting 296

cases where more than one fire department responded to the same fire incident (corresponding to 297

a “help code” of 3 or 4 in the database) were removed. Annual fire frequency analysis was 298

conducted in Microsoft Excel by creating a counting function for all fire incidents occurring in 299

the same city. Identified repeat fire incidents at a single site were further analyzed and incidents 300

within the same city that occurred at a different address but at a location greater than 5 miles 301

apart (as analyzed using Google Maps Engine) were treated as separate fire incidents. Landfills 302

with reported fire incidents were matched with landfills in the U.S. EPA Greenhouse Gas 303

Reporting database by matching the name and city (where available) of the site in each 304

respective database. In limited cases, sites of the same name had mismatching cities, in which 305

case the reported cities were mapped and those located within 5 miles of one another were 306

considered to be the same site. 307

Additional analyses and corresponding methods related to the Greenhouse Gas Reporting 308

dataset and the NFIRS database are provided in the Supplementary Information. 309
