EPA's Local Government Climate and Energy
Strategy Series
The Local Government Climate and Energy Strategy Series provides a comprehensive, straightforward overview of green-
house gas (GHG) emissions reduction strategies for local governments. Topics include energy efficiency, transportation,
community planning and design, solid waste and materials management, and renewable energy. City, county, territorial,
tribal, and regional government staff, and elected officials can use these guides to plan, implement, and evaluate their
climate change mitigation and energy projects.
Each guide provides an overview of project benefits, policy mechanisms, investments, key stakeholders, and other imple-
mentation considerations. Examples and case studies highlighting achievable results from programs implemented in
communities across the United States are incorporated throughout the guides.
While each guide stands on its own, the entire series contains many interrelated strategies that can be combined to create
comprehensive, cost-effective programs that generate multiple benefits. For example, efforts to improve energy efficiency
can be combined with transportation and community planning programs to reduce GHG emissions, decrease energy and
transportation costs, improve air quality and public health, and enhance quality of life.

EXECUTIVE SUMMARY
Developing and Implementing
Renewable Energy Programs
A growing number of local governments are turning
to renewable energy as a strategy to reduce GHGs,
improve air quality and energy security, boost the local
economy, and pave the way to a sustainable energy
future. Renewable energy resources—such as solar,
wind, biomass, hydropower, and landfill gas—reduce
GHG emissions by replacing fossil fuels. Renewables
also reduce emissions of conventional air pollutants,
such as sulfur dioxide, that result from fossil fuel
combustion. In addition, renewable energy can create
jobs and open new markets for the local economy, and
can be used as a hedge against price fluctuations of
fossil fuels. Local governments using renewable energy
can demonstrate leadership, helping to spur additional
renewable energy investments in their region.
Local governments can promote renewable energy
by using it to help meet their own energy needs in
municipal operations, and by encouraging its use by
local residents and businesses. The renewable energy
guides in this series present three strategies that local
governments can use to gain the benefits of renewables:
purchasing green power (see the guide on green power
procurement), generating energy from renewable
sources on-site (see the guide to on-site renewable
energy generation), and generating renewable energy
from landfill gas.
Use of Landfill Gas as a
Renewable Energy Resource
This guide describes how local governments and
communities can achieve energy, environmental,
health, and economic benefits by using landfill gas
(LFG) recovered from municipal solid waste landfills
as a source of renewable energy. As solid waste decom-
poses in landfills, a gas is emitted that is approximately
50 percent methane (CH4) and 50 percent carbon
dioxide (CO2), both of which are GHGs (U.S. EPA,
201 la). LFG energy technologies capture CH4 to
prevent it from being emitted to the atmosphere, and
can reduce landfill CH4 emissions by between 60 and
90 percent (depending on project design and effective-
ness) (U.S. EPA, 201 la). This guide describes technolo-
gies and strategies for recovering and using LFG as
an energy resource. It is designed to be used by local
governments, regulatory and planning agencies, devel-
opers, contractors, project partners, energy service
companies, and end users, including business and
industrial customers who work with project owners.
Readers of the guide should come away with an
understanding of options to recover and use LFG from
landfills, a clear idea of the steps and considerations
involved in developing and implementing LFG energy
projects, and an awareness of expected costs and
financing opportunities.
RELATED STRATEGIES IN THIS SERIES
1 Renewable Energy: Green Power Procurement
Green power is a subset of renewable energy that is
produced with no GHG emissions, typically from solar,
wind, geothermal, biogas, biomass, or low-impact small
hydroelectric sources. EPA recognizes LFG as a green
power source, and many local governments are purchas-
ing LFG energy products from private landfill or LFG
energy project owners and selling them to commercial
and residential customers to increase the use of renew-
able energy and reduce GHG emissions.
1 Renewable Energy: On-Site Renewable Energy
Generation
Local governments can implement on-site renewable
energy generation by installing wind turbines, solar
panels, and other renewable energy generating tech-
nologies, including LFG. Installing LFG equipment at
municipal facilities—and providing incentives to local
businesses and residents to do the same—can also be
an effective way to demonstrate a local governments
commitment to meeting community GHG emission
reduction goals.
1 Energy Efficiency: Combined Heat and Power
Combined heat and power (CHP), also known as cogen-
eration, refers to the simultaneous production of electric-
ity and thermal energy from a single fuel source. LFG can
be a fuel source for CHP systems, either on-site or piped
to nearby industrial or commercial users to provide a
second revenue stream for the project.

Relationships to Other Guides
in the Series
Local governments can use other guides in this series
to develop robust climate and energy programs that
incorporate complementary strategies. For example,
local governments can combine efforts to use LFG
energy with green power procurement, on-site
renewable energy generation, and use of LFG in
combined heat and power to achieve additional
economic, environmental, and social benefits associ-
ated with the use of renewable energy, energy efficiency
measures, and reduced GHG emissions.
See the box on page v for more information about
these complementary strategies. Additional connec-
tions to related strategies are highlighted in the guide.

Landfill Gas Energy
1. OVERVIEW
Many local governments across the United States are
achieving energy, environmental, health, and economic
benefits by utilizing technologies that capture methane
(CH4) from municipal solid waste (MSW) landfills,
preventing it from being emitted to the atmosphere,
and using it to produce various forms of energy,
including electricity, boiler fuel, steam, alternate
vehicle fuel, and pipeline quality gas (U.S. EPA, 201 la).
Landfill gas (LFG) energy projects employ proven tech-
nologies to capture LFG, a product of solid waste
decomposition in landfills that contains approximately
50 percent CH4 and 50 percent carbon dioxide (CO2),
both of which are greenhouse gases (GHGs).1 With a
heating value of about 500 British thermal units (Btu)
per standard cubic foot (scf), LFG is a good source
of energy.
METHANE FROM MSW LANDFILLS
CH4 is a hydrocarbon and the primary component of
natural gas. It is also a potent GHG with a global warming
potential more than 20 times that of CO2. MSW landfills
are the third-largest source of man-made CH4 emissions
in the United States, accounting for about 17 percent of
the country's CH4 emissions in 2009. Despite its potency
as a GHG, CH4 has a relatively short atmospheric lifetime
of 9-14 years, meaning projects that capture CH4 from
landfills offer a significant opportunity to mitigate
atmospheric concentrations of CH4 in the near-term.
Source: U.S. EPA, 2011a.
EPA estimates that as of July 2011, approximately 560
LFG energy projects were operational in the United
States. These projects generate approximately 1,730
megawatts (MW) of electricity per year and deliver 310
million cubic feet (ft3) per day of LFG to direct-use
applications. An additional 510 landfills present attrac-
tive opportunities for project development. If
1 LFG contains approximately 50% CH4 and 50% CO2. Small amounts of
non-methane organic compounds (NMOCs) and trace amounts of inorganic
compounds comprise less than 1% of the mix (U.S. EPA, 2011a). CO2 that
is emitted from LFG energy projects is not considered to contribute to global
climate change because the carbon was contained in recently living biomass
and would have been emitted through the natural decomposition process.
developed, these landfills have the potential to generate
an additional 1,170 MW of electric power or 590
million ft3 per day of LFG (U.S. EPA, 201 Ib). Counts of
these operational and potential LFG energy projects by
state are illustrated in Figure 1 on page 2.
EPA'S LANDFILL METHANE OUTREACH PROGRAM
The EPA Landfill Methane Outreach Program (LMOP) is
a voluntary assistance program that helps reduce GHGs
from landfills by encouraging the recovery and use of
LFG as a renewable energy resource. Launched by EPA
in 1994, LMOP forms partnerships with communities,
local governments, utilities, power marketers, states,
project developers, and nonprofit organizations
to overcome barriers to project development. For
additional information, please visit the LMOP Web site:
http://www.epa.gov/lmop/.

Most MSW landfills are owned either by local govern-
ments or the private sector. Similarly, the LFG energy
projects installed at local government-owned landfills
can be owned and operated by the local government or
a private developer hired by the local government—
both entities are referred to as "LFG energy project
owners" in this guide.
ENERGY FROM LFG AS A GREEN POWER SOURCE
Because of its superior environmental profile compared
to conventional energy, EPA recognizes LFG as a green
power source. For more information on green power,
see EPA's Green Power Procurement guide in the Local
Government Climate and Energy Strategy Series. For
more information on generating renewable energy at
local government facilities, see the guide on On-site
Renewable Energy Generation.

This guide highlights the local government and
community benefits of LFG energy projects at local
government-owned landfills. It provides informa-
tion on how local governments have planned and
implemented LFG energy projects to utilize CH4,
offers information on sources of funding, and presents
case studies. Additional examples and information
resources are presented in Section 10 on page 20,
Additional Examples and Information Resources.
2. BENEFITS OF LANDFILL
GAS ENERGY
Capturing LFG and using it as an energy resource can
produce significant energy, environmental, economic,
and other benefits. Specifically, using LFG helps local
governments to:
Reduce emissions of GHGs. MSW landfills are the
third-largest human-generated source of CH4 emis-
sions in the United States, releasing an estimated 27.5
million metric tons of carbon equivalent (MMTCE) in
2009 alone (U.S. EPA, 201 la). An LFG energy project
can reduce CH4 emissions from a landfill by between
60 and 90 percent, depending on project design and
effectiveness (U.S. EPA, 201 la). The annual CH4
(landfill methane) and CO2 (avoided fossil fuel usage)
emission reductions of a typical 3-MW electricity
generation project using LFG is about 34,700 metric
tons of carbon equivalent per year, the environmental
equivalent of the CO emissions from nearly 296,000
barrels of oil consumed. The annual CH4 and CO2
emission reductions of a typical direct-use LFG energy
project using 1,000 scf per minute (scfm)2 of LFG is
2 Scfm is a volumetric measurement that indicates how many ft3 of LFG pass
a stationary point in 1 minute under standard conditions.

-------
nearly 32,300 metric tons of carbon equivalent per
year, the environmental equivalent of the CO2 emis-
sions from more than 13.3 million gallons of gasoline
consumed (U.S. EPA, 201 lc).3
>\ The Lanchester Landfill LFG energy project in
JQ] f Narvon, Pennsylvania, is a 3,800 scfm project
IHl] that has annual avoided CO2 emissions of
12,900 metric tons of carbon equivalents, due to the
offset of fossil fuel usage. This reduction is equivalent
to the carbon sequestered annually by 10,100 acres of
pine or fir forests or the annual greenhouse emissions
from 9,060 passenger vehicles (U.S. EPA, 2007f).
Denton, Texas, took advantage of LFG to
10] f improve its local air quality. In 2004 and 2005,
I—I air quality testing in Denton County reflected
higher than acceptable levels of ozone concentra-
tions. To reduce vehicle pollution from its fleet, the
city established a public/private partnership to
construct and operate a biodiesel production facility
fueled by CH4 gas from the city's landfill. For three
years, the plant used the landfill CH4 as a fuel source
for biodiesel production. As a result, the city reduced
its emissions of criteria air pollutants and met federal
air quality standards by using alternative fuels for a
portion of its fleet. The city began utilizing the LFG
to generate electricity in 2008 (U.S. EPA, 2006; U.S.
Conference of Mayors, 2007).
IMPLICATIONS FOR THE ENVIRONMENT
In addition to providing a continuous source of
energy and improving local air quality, using LFG can
significantly reduce GHG emissions. Since its inception,
LMOP has helped 520 LFG energy projects in the United
States reduce landfill CH4 emissions and avoid CO2
emissions by a combined 44 million metric tons of
carbon equivalent (MMTCE). In 2010, reductions from all
operational LFG energy projects were equivalent to:
• Carbon sequestered annually by 20.7 million acres
of pine or fir forests; or
• Annual GHG emissions from 18.5 million passenger
vehicles.
Source: U.S. EPA, 2011d.
3 Combusting captured CH4 to generate electricity produces two byproducts:
water and CO2. The CO2 that is emitted from LFG energy projects is not
considered to contribute to global climate change because the carbon was
contained in recently living biomass and would have been emitted through the
natural decomposition process.
Generate additional revenue. Local governments can
earn revenue from selling LFG directly to end users or
into the pipeline, or from selling electricity generated
from LFG to the grid. Depending on who owns the
rights to the LFG and other factors, a local govern-
ment might also generate revenue by selling renewable
energy certificates (RECs), trading GHG emissions
offsets, and providing other incentives.
An LFG energy project at Catawba County's
Blackburn Landfill in Newton, North
Carolina, is expected to earn nearly $7
million over the project's lifetime and will allow
the county to keep its tipping fee constant for the
next 10 years (U.S. EPA, 2005a).
JACKSON COUNTY GREEN ENERGY PARK
Jackson County, North Carolina, has developed a Green
Energy Park that includes three professional blacksmith
studios and a series of greenhouses, and provides artisans
with free LFG to fuel kilns and other studio equipment. In
addition to achieving energy and environmental benefits,
the project supports local businesses and is expected to
add more than 20 jobs to the local economy when fully
operational.
Source: Jackson County, 2008.
Increase economic benefits through job creation
and market development. LFG energy project devel-
opment can greatly benefit the local economy. For
example, a typical 3-MW LFG electricity generation
project can create more than 20 jobs within the state
and local economies during its construction phase
(U.S. EPA, 2010a). LFG energy projects, which involve
engineers, construction firms, equipment vendors, util-
ities, and end users, also sustain certain jobs for each
year the project operates. In addition, some materials
and services are obtained from state and local econo-
mies. In some cases, new businesses (e.g., brick and
ceramics plants, greenhouses, and craft studios) have
located near a landfill to use the LFG for their work.
Demonstrate environmental leadership. Using LFG, a
green power source (see text box on page 1), can be
an effective way for local governments to demonstrate
environmental leadership and enhance community
awareness of the benefits of clean energy development.
2. BENEFITS
Energy Efficiency in Local Government Operations | Local Government Climate and Energy Strategy Series
-------
The EnergyXchange project in Burnsville,
North Carolina, demonstrates community-
level environmental stewardship. The project
was initiated with an LFG collection system at the
nearby Yancey-Mitchell Landfill. This action galva-
nized a community partner, Blue Ridge Resource
Conservation & Development Council, to organize
a Landfill Methane Task Force, which included
more than 140 people from 40 agencies and orga-
nizations. The Task Force determined the end
users for the LFG and identified operating part-
ners and resources crucial to the project.
EnergyXchange has become one of the nation's
model LFG energy recovery projects and is used
internationally as an example of a successful small
LFG energy project (EnergyXchange, 2010). The
environmental impact of the Yancey-Mitchell
County Landfill Reuse Project is equivalent to the
carbon sequestered annually by 950 acres of pine
or fir forests or the annual greenhouse gas emis-
sions from 850 passenger vehicles (U.S. EPA,
201 Ic).
Reduce environmental compliance costs. Current
EPA regulations under the Clean Air Act (CAA)
require landfills with capacities greater than 2.5 million
megagrams (Mg) of MSW and NMOC emissions of 50
Mg per year to capture and combust LFG to prevent
NMOCs from contributing to smog formation and
threatening air quality. LFG energy projects offer the
opportunity to reduce the costs associated with regula-
tory compliance by turning pollution into a valuable
renewable energy resource (U.S. EPA, 201 la).
In 1990, Glendale, California, was
confronted with the challenge of complying
with increasingly stringent environmental
regulations governing the operation of power
plants and landfills. The city reviewed its options,
and implemented an LFG energy project to deliver
LFG to a local generating station and use it as a
base fuel along with natural gas or fuel oil. The
composition of LFG offered the opportunity to
further reduce emissions of nitrogen oxides (NOX)
during electric power generation. The city was able
to simultaneously comply with the regulations,
generate tangible environmental benefits, and
lower costs for the consumer (Power Engineering,
1995).
Improve air quality. Collecting LFG to produce energy
improves the air quality of the surrounding commu-
nity by reducing emissions of criteria pollutants and
hazardous air pollutants (HAPs) and minimizing land-
fill odors. Capturing and utilizing LFG directly avoids
emissions of NMOCs, components of untreated LFG
that can contribute to smog formation. In addition,
using LFG can indirectly avoid emissions of several
criteria pollutants, including sulfur dioxide (SO2, a
major contributor to acid rain), particulate matter (a
respiratory health concern), NOX, and trace HAPs that
would result from using fossil fuels in conventional
energy generation (U.S. EPA, 201 la).4 CH4 captured
from landfills can be used as an alternative fuel that
burns cleaner than traditional fuels.
Conserve land. LFG energy projects can enhance
solid waste decomposition, increase landfill capacity,
and mitigate the need to build new landfills or expand
existing ones.
LaGrange, Georgia, has achieved gains of 15
to 30 percent in landfill capacity as a result of
an LFG energy project initiated in 2001
(SGPB, 2008).
Riverview, Michigan, developed an LFG
energy project on a 212-acre landfill owned
by the city. The LFG is used to create elec-
tricity with two gas turbines. The local utility
purchases the electricity under a 25-year power
purchase agreement. Benefits to the community
from the closed landfill include its use as a winter-
time skiing and recreation area and a future golf
practice facility (U.S. EPA, 2007g).
Create other benefits. By linking communities with
innovative ways to deal with their LFG, LFG energy
projects offer increased environmental protection,
better waste management, and responsible commu-
nity planning, all of which are top priorities for local
governments (US. EPA, 201 la).
4 LFG electricity generation systems, like all electricity generation combus-
tion systems, generate some emissions ofNOy a criteria pollutant that can
contribute to local ozone and smog formation. Depending on the LFG energy
project, the NOX emission reductions from the power plant may not completely
offset the NOX emitted from the LFG electricity project (U.S. EPA, 2011a).
2. BENEFITS

-------
>\ The CommunityTIES Project is an LFG
iQjr development initiative that works with a
I—I cluster of counties in North Carolina to facil-
itate the development of community-based LFG
energy projects which generate local economic
development. The statewide project is managed by
the Appalachian State University Energy Center
with funding from the GoldenLEAF Foundation,
the North Carolina State Energy Office, and the Z.
Smith Reynolds Foundation (CommunityTIES
Project, 2008).
LFG collection can also improve safety by reducing
explosion hazards from gas accumulation in structures
on or near the landfill (U.S. EPA, 201 la).
3. LANDFILL GAS ENERGY
TECHNOLOGIES
A number of factors, including the availability of an
energy market, project costs, potential revenue sources,
and other technical considerations, can determine
which technologies are most appropriate for a partic-
ular LFG energy project. Technologies for converting
LFG into energy include:
Electricity generation. Approximately 70 percent of
the LFG energy projects currently in operation in the
United States are used to generate electricity, for on-site
use and/or to sell to the grid (U.S. EPA, 201 la). (For
more information on using on-site renewable energy
generation systems, see EPAs On-Site Renewable
Energy Generation guide in the Local Government
Climate and Energy Strategy Series.) Electricity from
LFG can be generated using a variety of technologies,
including internal combustion engines, gas turbines,
and microturbines, with 85 percent of LFG electricity
generation projects using internal combustion engines
or turbines.5 One million tons of landfilled MSW can
produce an electricity generation capacity of 0.8 MW
(U.S. EPA, 2009c).
5 Microturbine technology is sometimes used at smaller landfills and in
highly specialized applications. Less common LFG electricity generation
technologies include boiler/steam turbine applications in which LFG is
combusted in a large boiler to generate steam, which is then used by the
turbine to generate electricity; and combined cycle operations that combine
a gas turbine, which combusts the LFG, and a steam turbine, which uses
steam generated from the gas turbine's exhaust to create additional electricity
(U.S. EPA 2009d).
The Lancaster County Solid Waste Authority,
in Pennsylvania, generates 3,200 kilowatts
I—I (kW) of electricity through a partnership
with a local energy company, PPL Energy Services.
The electricity is produced from two LFG-fired
generators. For two years, boilers captured waste
heat to provide steam to the nearby Turkey Hill
Dairy, a well known maker of ice cream and dairy
products (U.S. EPA, 2007e).
Direct use of LFG. Direct use of LFG, which involves
transmitting the medium-Btu gas via pipeline to be
combusted by an end user, accounts for approximately
30 percent of all LFG energy projects in the United
States (U.S. EPA, 201 la). LFG can be used by end users
to fuel boilers, dryers, kilns, greenhouses, and other
thermal applications. Current industries using LFG
include automobile manufacturing, chemical produc-
tion, food processing, pharmaceutical, cement and
brick manufacturing, wastewater treatment, consumer
electronics and products, and prisons and hospitals
(U.S. EPA, 2009c). One million metric tons of land-
filled MSW can produce between 8,000 and 10,000
pounds of steam per hour when LFG is used to fuel
a boiler (U.S. EPA, 2009d). The economics of an LFG
energy project improve the closer the landfill is to the
end user. The piping distance from a landfill to its LFG
end user is typically less than 10 miles, although piping
LFG up to 20 miles can be economically feasible,
depending on the amount of gas recovered at the land-
fill and the energy load of the end-use equipment (U.S.
DOE, Undated).
Combined heat and power. One specific type of LFG
use is as a fuel source for combined heat and power
(CHP) or cogeneration systems that generate both elec-
tricity and thermal energy. CHP systems can achieve
substantially higher efficiencies than separate heat and
power systems that do not use the waste heat produced
in electricity generation. Thermal energy cogenerated
by LFG energy projects can be used for on-site heating,
cooling, and/or process needs, or piped to nearby
industrial or commercial users to provide a second
revenue stream for the project (U.S. EPA, 2009d).
CHP is often a better economic option for end users
located near the landfill or for projects where the
end user requires both electricity and waste heat. For
more information on CHP, see EPAs Combined Heat
and Power guide in the Local Government Climate and
Energy Strategy Series.

In Antioch, Illinois, the local high school is
purchasing electricity and by-product heat
from a nearby privately owned LFG energy
cogeneration project that uses 12 30-kW microtur-
bines. Purchasing electricity and heat generated at
the landfill saves the school nearly $100,000 annu-
ally in energy costs (RMT, 2008).
ADDITIONAL RESOURCES ON CHP APPLICATIONS
For additional information on CHP, see EPA's Combined
Heat and Power guide in the Local Government Climate
and Energy Strategy Series and EPA's Combined Heat and
Power Partnership at http://www.epa.gov/chp.
Alternate fuels. Production of alternate fuels from
LFG is an emerging area and can involve several tech-
nologies, including:
>• Pipeline fuel. Municipalities can deliver LFG to
the natural gas pipeline system as both a high- and
medium-Btu fuel. Upgrading LFG to produce
high-Btu gas involves separating CH4 from the
CO2 component of LFG. The separated CH4 can
be sold to natural gas suppliers or used in applica-
tions requiring high-Btu fuel. Although expensive,
newly developing technologies are reducing the
cost of these types of projects, which are ideally
suited for larger landfills located near natural gas
pipelines.
/S. In King County, Washington, the county
is working with a project developer to
produce pipeline quality natural gas
from the LFG captured at the Cedar Hills
Regional Landfill. The county expects to
receive $1.3 million annually through a
contract with a natural gas provider. Other
benefits include an estimated annual avoid-
ance of CO2 emissions equivalent to the
annual GHG emissions from 17,500 passenger
vehicles (U.S. EPA, 201 Ic), and reduced GHG
emissions of approximately 60 percent (King
County, 2007; 2008).
Vehicle fuel. LFG can also be converted to vehicle
fuel. Vehicle fuel applications involve using LFG
to produce compressed natural gas (CNG), lique-
fied natural gas (LNG), or methanol. This process
involves removing CO2 and other trace impurities
from LFG to produce a high-grade fuel that is at
least 90 percent CH4. Currently, CNG and LNG
vehicles comprise a very small portion of automo-
biles in the United States, so there is not a signifi-
cant demand for these vehicle fuels. However, with
growing interest in alternative fuels, demand is
expected to increase.
Waste Management, Inc. uses LFG from
its Altamont Landfill in Livermore,
California, to create LNG for use in
garbage trucks (U.S. EPA, 2010b).
DENTON, TEXAS-BIOFUEL PROCESSING
LFG captured from the Denton, Texas, landfill was piped
to a local biodiesel facility for three years where it was
combusted to heat renewable feedstock to produce B20
biodiesel (20 percent biodiesel, 80 percent diesel) fuel
for the city's vehicle fleet. The project was expected to
reduce the fleet's emissions of criteria pollutants by 12
tons annually.

4. KEY PARTICIPANTS
A number of participants can play a key role in plan-
ning, designing, and implementing an LFG energy
project, including:
Local government officials and staff. Local officials
often begin the process of implementing LFG energy
projects. The mayor or county executive can play a
key role in increasing public awareness of the benefits
of LFG energy. Including LFG goals in a mayor's or
county executive's priorities can lead to increased
funding for LFG energy potential studies and/or proj-
ects. In other cases, LFG energy projects are often initi-
ated by city and county councils and/or staff. Securing
support from city or county council members can be
important for ensuring that LFG initiatives receive the
resources necessary to produce results.

includes nearly 200 extraction system wells that are
used to collect LFG. The captured gas is used to
generate 6 MW of electricity, enough for about 5,000
homes. The gas is also sent to the nearby Noman Cole
Wastewater Treatment Plant, where it is used as a
medium-Btu fuel in the sludge combustion process
(MWCG, 2006; Fairfax County, 2007).
Developers. While some local governments choose to
self-develop LFG energy projects, many hire outside
developers to finance, construct, own, and/or operate
these projects. Developers are typically private compa-
nies that specialize in the various stages of building,
owning, and operating LFG energy projects. In many
instances, the local government retains ownership of
the landfill while the developer assumes ownership of
the LFG energy project.6
Regulatory and planning agencies. LFG energy
project owners prepare applications for zoning or land
use permits, air permits, and conditional use permits.
LFG energy project owners typically involve state
environmental regulatory/permitting agencies, state
energy agencies, and state public utility commissions
early in the project planning process to ensure that all
parties understand applicable environmental and land
use requirements. In addition to state regulatory agen-
cies, project owners often consult with county board
members, local solid waste planning boards, and local
zoning and planning departments. These partners are
mainly involved during the permitting process of the
facility. Project owners need to provide information
showing that the project will meet emissions limits
and other requirements, and will need to demonstrate
compliance once the project becomes operational.7
Financial partners. LFG energy project owners
sometimes work with financial partners (e.g., tax credi-
tors, bankers, and accountants) that provide financial
assistance, prepare tax credit documentation, and
track project finances. Tax creditors can assist LFG
energy project owners in applying for federal, state,
or local renewable energy tax credits. Bankers can
6 This guide uses the term "LFG energy project owner" to refer to either the
local government or the developer it hires to construct and operate an LFG
energy project.
7 Each state has different regulations and procedures for compliance and
regulations. Some of these regulations can be found at: http://www.dsireusa.org.
help LFG energy project owners fund the LFG energy
project, and accountants assist by tracking finances and
revenues for the LFG energy project owner.
Professional partners. LFG energy project owners
often obtain legal, marketing, or technical services for
an LFG energy project from a range of professional
partners. For example, consulting engineers provide
technical services and can assist in designing and
constructing the project and keeping the project in
regulatory compliance. Lawyers draw up and review
contracts for multiple purposes, including protecting
the LFG energy project owner from liability and
establishing agreements between local governments
and developers, end users, and other consultants or
contractors. Lawyers might also review legal aspects
of tax credits and project structures. Communications
specialists or public information personnel can assist
in fostering interaction with local residents, publicizing
the environmental benefits of the LFG energy project,
and preparing educational materials.
Contractors. LFG energy project owners typically
employ a variety of contractors to implement specific
activities during the project planning, design, and
implementation phases. Key types of contractors
include:
Construction contractors building the facility;
Generator manufacturers providing project
owners with manufacturing data on generator
equipment to help them determine which type
of generator best fits the design and operating
requirements of the LFG energy project;
Generation plant operators operating and main-
taining the facility, and providing energy output
data, testing data, and maintenance information to
the project owner;
LFG treatment system manufacturers providing
LFG energy project owners with design and
product specification assistance and working with
the project owners, consultants, and end users to
design, supply, and assemble the proper equipment
to treat the LFG;

Testing laboratories working with LFG energy
project owners to ensure that energy genera-
tion equipment does not emit higher levels than
allowed by regulations and air permits; and
Wellfield operators helping to ensure that the
landfill is in compliance with local air permitting
regulations, operating and maintaining the gas
extraction wellfield, and making tuning adjust-
ments necessary to collect the LFG.
Energy service companies. LFG energy project
owners sometimes work with energy service compa-
nies (ESCOs) that provide a comprehensive package of
products and services to install, operate, and maintain
LFG energy projects.
Little Rock, Arkansas, worked with an ESCO
to construct an LFG energy project at the
city's landfill. As part of the services package,
the ESCO monitors and maintains the project and
its pipelines. In addition, the ESCO helped the city
reach an agreement with a local company to have a
portion of the collected LFG piped to that
company for use in a production facility (Little
Rock, 2007).
End users. LFG energy project owners often sell
the energy generated by LFG energy projects to end
users, including business and industrial customers,
for direct use in boilers, heaters, kilns, furnaces, and
other combustion equipment at their facilities. Project
owners also sell electricity generated on-site by the
LFG energy project to end users. Some end users can
use LFG to produce their own electricity, as a feedstock
for a chemical process, or for other purposes. In some
instances, LFG energy project owners work with
potential end users when developing projects to tailor
the project to meet the end user's energy needs.
For the previously mentioned project in
Little Rock, Arkansas, the city entered into
an agreement with a local business to capture
LFG from the city landfill and pipe it for direct use
at the company's production facility. The city bene-
fits from the LFG sale revenues, while the business
benefits from below-market rate gas prices (Little
Rock, 2007).
Utilities. LFG energy project owners sometimes sell
LFG, or the electricity it generates, to local utilities.
Whether investor-owned or municipally owned, local
utilities can use electricity generated from LFG energy
projects to meet renewable portfolio standards that
mandate specific percentages of renewable energy in a
utility's supply.
In Denver, Colorado, the local government is
partnering with the private corporation that
manages the city-owned landfills to develop
a 3.2-MW electricity generation plant that will
supply electricity to the local utility (Denver,
2007).
Community partners. When LFG energy project
owners apply for permits, community members
express questions, concerns, or opposition to the
proposed facility during a public comment period.
Depending on the public comment results, permits
are issued, modified, or rejected. Local governments
often work with landfill neighbors, local businesses,
and environmental and community organizations to
address any community concerns early in the project
development stage. Local governments can work
with the community to design a project that complies
with community zoning and other ordinances, and
provides environmental and economic benefits to the
surrounding community.
The CommunityTIES Project emphasizes the
importance of community groups in project
development. While CommunityTIES
provides technical, financial, and other support for
local projects, the single most important success
factor for its partner counties is building a team of
local stakeholders to drive projects from conceptu-
alization to end use operations. The
CommunityTIES Project does not develop LFG
energy projects so much as it develops the capa-
bilities in local communities to develop their own
projects. (CommunityTIES Project, 2008).

5. FOUNDATIONS FOR
PROJECT DEVELOPMENT
Mechanisms that local governments have used to
initiate LFG energy projects in their communities and
promote the use of LFG as a renewable energy resource
include:
Executive or city council initiatives. Mayors, county
executives, and city councils have been influential in
initiating and promoting LFG energy projects in their
communities, helping to sustain community support
for LFG energy projects and ensure that projects
receive sufficient funding.
The city council of Albuquerque, New
1 ffl f Mexico, established a renewable energy
I—I initiative that included LFG energy as a
priority. One of the city's recent projects consists
of a 70-kW microturbine that captures the LFG
and produces electricity (Albuquerque, 2008).
Renewable portfolio standards (RPS). A number of
local governments have adopted an RPS that requires
municipally owned electric utilities to use a certain
percentage of renewable energy in their overall energy
supply.
The city council of Burbank, California,
established an RPS requiring the Burbank
Water and Power utility to use 20 percent
renewable power by 2017. One component of the
utility's strategy for meeting this goal is to use LFG
captured at the local landfill, where two microtur-
bine systems have been installed, with a total
capacity of 550 kW (Burbank, 2006).
Commitments to purchase LFG from private
landfill owners. A number of local governments are
purchasing LFG energy products from private landfill
or LFG energy project owners. Some municipally
owned utilities are purchasing green power from
private landfill owners and selling it to commercial and
residential customers.
In 2007, the city council in Anaheim,
California, approved purchase agreements
with two private LFG energy project owners
to obtain 30 MW of LFG-based electricity capacity
for its municipally owned utility, which has estab-
lished a goal of increasing the amount of green
power in its portfolio to 14 percent by 2010
(Anaheim, 2007).
For more information on purchasing green power
products, see EPA's Green Power Procurement guide
in the Local Government Climate and Energy Strategy
Series.
6. STRATEGIES FOR
EFFECTIVE PROJECT
IMPLEMENTATION
Local governments can consider a number of
approaches to help them overcome barriers to imple-
menting LFG energy projects, including:
Evaluate site candidacy. The first consideration for
an LFG energy project owner is to determine whether
the landfill is a candidate for LFG recovery. In general,
strong candidate landfills should contain at least 1
million tons of waste, have an average depth of 50
feet or more, and be open or have closed within the
last five years (these are general guidelines to which
there are exceptions). After this initial screening, the
project owner determines LFG recovery rates. EPA's
Landfill Gas Emissions Model (LandGEM) can provide
a more detailed analysis of LFG generation potential
(available at: http://www.epa.gov/ttn/catc/products.
html#software). The LFG energy project owner can
also engage an engineering consulting firm to conduct
a desktop feasibility study to assist with this task. In
addition, LFG energy project owners can consider the
distance between the landfill and anticipated end users.
The piping distance from a landfill to a potential LFG
end user is typically less than 10 miles, although piping
LFG up to 20 miles can be economically feasible,
depending on the amount of gas recovered at the land-
fill and the energy load of the end-use equipment (U.S.
DOE, Undated).
Weigh the options of different technologies.
As mentioned in Section 3, Landfill Gas Energy
Technologies, there are a number of different ways
to convert LFG into energy. The best option for a
5. FOUNDATIONS-6. STRATEGIES
Energy Efficiency in Local Government Operations | Local Government Climate and Energy Strategy Series
-------
particular landfill will depend on a variety of factors,
including the availability of a market for energy,
project costs, existence of a nearby end user, potential
revenue sources, and other technical considerations.
In general, the simplest and most cost-effective option
is to sell medium-Btu gas to a nearby customer for
direct use—this requires minimal processing and is
tied to retail gas rates rather than utility buy-back rates.
Power production and sale to a nearby utility can also
be a cost-effective option if utility electricity buy-back
rates are attractive. Other options, such as upgrading
LFG to a high-Btu product for injection into a natural
gas pipeline, entail higher capital and treatment costs
and may only be cost-effective for those landfills with
substantial recoverable gas.
Consider whether to engage a partner. Some local
governments have the expertise, resources, and desire
to lead the project development effort on their own.
However, in many cases, choosing the right develop-
ment partner can greatly improve the likelihood of a
project's success. From a local government's perspec-
tive, there are three ways to structure the development
and ownership of an LFG energy project:
Develop the project internally, where the local
government manages the development effort and
maintains ownership control of the project;
Team with a project developer who develops and
builds the project;
Team with a partner, where the local government
works with an equipment vendor, an engineering/
procurement/construction (EPC)firm, an indus-
trial company, or a fuel company to develop the
project and share the risks and financial returns.
At the St. John's LFG energy project in
Portland, Oregon, public and private entities
worked together to pipe LFG from St. John's
Landfill to a nearby lime plant for use as a primary
fuel source for three lime kilns. Metro, a Portland
regional planning authority, worked with Portland
Landfill Gas Joint Venture Partners, which
included a cement company and an investment
banking firm, to develop the project (U.S. EPA,
2007h).
In Pennsylvania, the Clinton County Solid
Waste Authority searched for a way to
control the gas generated by the Wayne
Township Landfill. Wayne Township teamed with
a neighboring steel company to develop an LFG
energy project and share both risks and financial
returns. Through this partnership project, the
Authority provides 970 scfm of LFG to the steel
company to use as fuel in their furnace to reclaim
railroad steel. This project has been a new source
of revenue for the Authority and enabled the steel
company to save on fuel costs (U.S. EPA, 2007i).
Retain or sell RECs. RECs (also known as green
tags, green energy certificates, or tradable renew-
able certificates) represent the environmental and
other non-power attributes of electricity generated
from renewable resources. They provide information
about the generation resource (e.g., LFG), when the
megawatt-hour (MWh) was generated, and the loca-
tion of the generator. It is important to note though,
that while some states define RECs to include the
environmental and climate benefits associated with the
CH4 destruction, others do not. In the latter case, the
environmental benefit is captured separately and can
be sold as a carbon offset.
When renewable energy is generated, the RECs may
be separated from the physical electricity and sold as
a distinct product. The REC buyer gains the contrac-
tual rights to make an environmental marketing claim
and the physical electricity—that is sold separately—
becomes "attributeless" or "null power" (i.e., environ-
mentally equivalent to the regional power mix). In
making a REC claim, the buyer permanently "retires"
the REC and it can no longer be sold.
There are two types of markets for RECs: compli-
ance markets created by state-mandated RPS for
retail electricity sales and a voluntary market driven
by residential and business demand for zero emis-
sion electricity from renewable resources. Local
governments can target the following purchasers of
RECs from LFG energy projects: (1) electric service
providers, for compliance with state RPS or to supply
retail green power programs; (2) non-utility whole-
salers and retailers, including REC marketers and REC
brokers; and (3) retail customers (WRI, 2003; U.S. EPA,
2004).

6. STRATEGIES
Energy Efficiency in Local Government Operations | Local Government Climate and Energy Strategy Series
-------
In 2008 in Massachusetts, the state RPS
required electric retailers to acquire RECs
I—I from qualified renewable energy generation
projects (including LFG energy projects) to cover
3.5 percent of their 2008 sales. These RECs were
sold to the retailers through the New England
Power Pool General Information System
(NEPOOL CIS) for more than 4
-------
organizations. It is important to engage these part-
ners early in the project development phase. LFG
energy project owners can work with the community
to address any concerns and to select a project that
complies with community zoning and other ordinances
and has environmental and economic benefits to the
surrounding community.
Understand the community's role in permitting and
compliance issues. Unless there is significant opposi-
tion to an LFG energy project, community partners
are mainly involved in the permitting process. When
such as air and zoning permits, community members can
provide comments during the public comment period.
For a detailed example on how to engage the community,
see Section 9, Case Studies: Yancey and Mitchell Counties,
North Carolina—EnergyXchange Renewable Energy
Center on page 19.
The text box below provides a basic overview for local
governments and other entities interested in developing
an LFG energy project.
STEPS FOR DEVELOPING LFG ENERGY PROJECTS
1. Estimate LFG recovery potential. Strong candidates for LFG energy projects include landfills that: contain at least 1 million tons of
MSW, have a depth of 50 feet or more, and are open or recently closed (U.S. EPA, 2009a). In addition, the site should receive more than
25 inches of precipitation annually (U.S. EPA, 2009a). EPA's LandGEM can provide a more detailed analysis of LFG generation potential
(available at http://www.epa.gov/ttn/catc/products.htmlffsoftware).
2. Evaluate project economics. Local governments can evaluate the economic potential for converting LFG by using EPA's LFGcost-
Web tool to help with preliminary economic evaluation, which includes public financing inputs (available to LMOP Partners at
http://www.epa.gov/lmop/publications-tools/index.htmlffthree).
3. Establish project structure. Local governments can work with a developer or other partners. If a local government decides to
work with partners, the terms of the partnership should be formalized in a contract that specifies which partner will own the gas
rights and the rights to potential emissions reductions, and outlines partner responsibilities for design, installation, and operation and
maintenance (O&M).
4. Assess financing options. Local governments can consider a number of financing options, including private equity financing, project
finance, municipal bond financing, direct municipal funding, lease financing, and public debt financing through institutional or public
stock offerings. For more information, see Section 7 Costs and Financing Opportunities on page 13.
5. Negotiate energy sales contract. Local governments can enter into contracts to sell LFG to end users. Negotiating sales contracts
involves preparing a draft offer, determining utility or end user need for power or gas demand, developing project design and pricing,
preparing and presenting a bid package, reviewing contract terms and conditions, and signing the contract.
6. Secure permits and approvals. The permitting process for an LFG energy project may require six to 18 months (or longer), depending
on the project's location and recovery technology. LFG energy projects must comply with federal regulations relating to LFG
emissions controls and control of air emissions from the energy conversion equipment. LMOP's State Resources page provides links to
information regarding state specific regulations and permits. See: http://www.epa.gov/lmop/publications-tools/state-resources.html.
7. Contract for engineering, procurement, construction, and O&M. Construction and operation of LFG energy projects are often best
managed by firms with proven experience. Contractors can conduct engineering designs, site preparation, plant construction, and
start-up testing.
8. Install project and start up commercial operation. The final phase of implementation is to start commercial operations and engage
the community in educational outreach programs.

7 COSTS AND FINANCING
OPPORTUNITIES
This section provides information on the costs of eval-
uating, constructing, and installing LFG energy proj-
ects at local government-owned landfills and describes
financing opportunities for addressing these costs.
Costs
In general, each LFG energy project involves project
evaluation, purchase and installation of equipment
(capital costs), and the expense of operating and main-
taining the project (O&M costs). This section describes
the costs involved in project evaluation, collection
system and flaring, electricity generation, direct LFG
use, and other LFG uses.
LFG ENERGY PROJECT COSTS
LMOP has developed LFGcost-Web, a tool to help with
preliminary project economic evaluation. It is available
at: http://www.epa.gov/lmop/publications-tools/index.

Project evaluation costs. The initial cost involved in
implementing an LFG energy project involves
conducting a feasibility study to determine project
potential. A typical desktop feasibility study involves
gas recovery modeling, pro forma financial analysis,
site visits, and an evaluation of end-use options.
Engineering consulting firms can perform these
studies, with costs ranging from $10,000 to $15,000 per
study. A more detailed study involving further gas
analysis (including tests for CH4, hydrogen sulfide, or
siloxanes) may cost an additional $10,000.
1 Collection system and flaring costs. Gas collection
and flaring system equipment gathers LFG to be
combusted for electricity generation or to be distrib-
uted for direct use, and provides a way to destroy the
gas when the project is not operating. If a collection
and flare system already exists, it can be treated as
a "sunk cost,"9 and the project cost only needs to
consider necessary modifications to the system. The
typical LFG collection and flare system costs approxi-
mately $24,000 per acre for installed capital costs, with
annual O&M costs of approximately $4,100 per acre
(U.S. EPA, 2009b).
CONSIDERATIONS FOR COLLECTION SYSTEM AND
FLARING COSTS
Collection system and flaring costs can vary depending
on design variables. Key factors that influence costs
include:
• For gas collection wells or collectors: depth of the
waste and spacing of wells or collectors.
• For gas piping: gas volume and length of piping.
• For the condensate knockout drum: volume of the
drum.
• For the blower: blower size.
• For the flare: flare type (enclosed or open, ground
or elevated) and size.

Electricity generation project costs. The most
common technologies for converting LFG into
electricity include internal combustion engines, gas
turbines, microturbines, and small engines. Each
technology is generally suited to a particular range in
project capacity. Internal combustion engines, the most
commonly used engines in LFG electricity generation
projects, tend to be used for projects in the 800-kW to
3-MW capacity range, while gas turbines are typically
used for projects that have capacities of 3 MW or more
(U.S. EPA, 2009b). Microturbines and small internal
engines are best suited for small projects in the 250-kW
to 1 -MW range or for projects with unique power
needs (U.S. EPA, 2009b). Table 1 illustrates typical
capital and O&M costs for different electricity project
options.
9 Sunk costs are defined as costs that have been incurred and that cannot be
recovered to any significant degree.

Direct-use project costs. For direct-use LFG energy
projects, costs vary depending on the end-user's require-
ments, but typically include expenses for the following
components: gas compression and treatment systems to
condition gas for end-user equipment, pipelines to trans-
port LFG to the end user, and condensate management
systems for removing condensate along the pipeline.
Typical costs for gas compression and treatment are
about $960 per scfm with O&M costs of $90 per scfm.
For gas pipeline and condensate management systems,
the typical capital costs are about $330,000 per mile with
negligible O&M costs (U.S. EPA, 2009b).
End users may need to modify their equipment to
make it suitable for combusting LFG, but these costs
are usually borne by the end user and are site-specific.
However, modification costs are typically offset by cost
savings as a result of purchasing energy at below-market
rates.10
Other project type costs. In addition to electricity
generation and direct-use projects, there are other less
common project options including CHP applications,
leachate evaporation, vehicle fuel, and upgrade to high-
Btu gas for sale to natural gas distribution companies.
These technologies are not as universally applicable
as the more traditional LFG energy projects; however,
depending on the specific situation, they can be very
cost-effective.
10 LMOP provides a boiler retrofit fact sheet to help end users understand the
types of modifications required to use LFG in a boiler (see http://www.epa.gov/
Imop/documents/pdfs/boilers.pdf).
PLANNING FOR LFG ENERGY PROJECT SUCCESS
In successful projects, local governments keep detailed
records, are conservative about the energy potential
from the landfill, review all pro forma statements, and
assist the procurement process in anyway possible,
to build public support and ensure sound and efficient
financial transactions. These steps minimize permitting
delays and enhance public support, which help increase
the attractiveness of the project to investors.
Source: U.S. EPA, 2009b.
Financing
A combination of different financing options may be
the best approach for funding an LFG energy project.
Financing options available to LFG energy project
owners include:
Municipal bond financing. For municipally owned
landfills or end users, the issuance of tax deferred
bonds can be used to finance LFG energy projects. This
is the most cost-effective method of financing a project
since the interest rate is often 1 or 2 percent below
commercial debt interest rates and can often be struc-
tured for long repayment periods (U.S. EPA, 2009b).
Direct municipal funding. Often the lowest-cost
financing available, direct municipal funding uses
the local government operating budget to fund the
LFG energy project, eliminating the need for outside
financing or obtaining partners and delays caused from
their project evaluation needs. However, municipalities
may not have sufficient budgets to finance a project.
14
7. COSTS & FINANCING OPPORTUNITIES

-------
Additionally, public approval may be required for LFG
energy projects, which can increase the time required
to complete a project.
Fargo, North Dakota, financed an LFG
collection and flare system to reduce odors
from landfill operations. A neighboring
company that processes oilseed recognized the
energy potential and approached the city about
using LFG in their boilers. The city and the oilseed
processor split the cost of the 1.5-mile pipeline,
and the oilseed processor financed the installation
of dual-fuel burners and the new control system.
The city will recover its capital expense through
the sale of LFG (U.S. EPA, 2007b).
Private equity financing. This financing approach
involves an investor who is willing to fund all or a
portion of the project in return for a share of project
ownership. Potential investors include developers,
equipment vendors, gas suppliers, industrial compa-
nies, and often investment banks. For small projects
without access to municipal bonds, private equity
financing can be one of the better means of obtaining
financing. This option typically has lower transaction
costs and usually enables a local government to move
faster on financing than with other options. However,
private equity financing can be more expensive than
other financing options. In addition, investors may
expect to receive benefits from providing funding, such
as service contracts or equipment sales, as well as a
portion of the cash flow.
EPA'S LANDFILL METHANE OUTREACH PROGRAM
FUNDING RESOURCES
LMOP has developed a comprehensive funding guide
that provides information about a broad range of types
of funding options available for LFG energy projects.
The guide provides examples of successful funding
approaches that can be replicated around the country to
promote LFG energy. The types of funding covered in the
guide include grants, loans, tax credits and exemptions,
and production incentives. Information about state RPSs
that include LFG as an eligible resource is also provided.
For further information, see http://www.epa.gov/lmop/
publications-tools/funding-guide/index.html.

Project finance. With this approach, often used for
private power projects, lenders look to a project's
projected revenues rather than the assets of the
developer to ensure payment. The developer retains
ownership control of the project while still obtaining
financing. Typically, the best sources for obtaining
project financing are from small investment capital
companies, banks, law firms, or an energy investment
fund. The main disadvantages of project finance are
high transaction costs and the lender s high minimum
investment threshold.
Lease financing. For this approach, the project owner
leases all or part of the LFG energy project assets.
This arrangement usually allows the transfer of tax
benefits or credits to an entity that can best make use
of them. Lease arrangements can allow for the user to
purchase the assets or extend the lease upon comple-
tion of the lease. The benefit of lease financing is that
it frees up the project owner s capital funds, while
allowing the owner to maintain control of the project.
Disadvantages include complex accounting and
liability issues, and the loss of tax benefits to the project
owner.
Renewable energy trust funds. Some local govern-
ments have been awarded grants to fund LFG energy
projects through renewable energy trust funds admin-
istered by nonprofit organizations, state agencies, or
other sources. The Renewable Energy Trust in
Massachusetts is funded by a public benefits fund and
administered by the Massachusetts Technology
Collaborative.
The Renewable Energy Trust provided the
town of Barnstable, Massachusetts, with a
$20,000 grant to evaluate the feasibility of
powering a new town facility with LFG captured
from the town's landfill (MTC, 2005).
DATABASE OF STATE INCENTIVES FOR RENEWABLE
ENERGY
The Database of State Incentives for Renewables &
Efficiency (DSIRE) is another resource for funding and
other incentives for LFG energy projects. For more
information, see http://www.dsireusa.org/.

7. COSTS & FINANCING OPPORTUNITIES

-------
Loans. Local governments can obtain low-interest
loans from federal or state agencies to finance LFG
energy projects.
LaGrange, Georgia, used a $1 million low-
interest loan from the Georgia
Environmental Facilities Authority, under
the agency's Solid Waste Loan Program, to
upgrade its landfill management equipment and to
install a gas collection facility at the landfill (U.S.
EPA, 2008a).
Property and sales tax exemptions. Exempting LFG
energy projects from state taxes is another powerful
incentive to encourage new projects. Some states have
exempted equipment that generates energy from LFG
from state sales and use taxes or from state property
taxes.
Maryland's Clean Energy Incentive Tax
Credit is an example of a program to provide
tax credits to facilities that produce energy
from biomass (including LFG). Qualifying facili-
ties can claim a credit on their state income taxes
(MEA.2012).
8. FEDERAL, STATE,
AND OTHER PROGRAM
RESOURCES
A number of federal, state, and other programs can
offer technical assistance and information resources to
local governments.
Federal Programs
Global Methane Initiative. The Global Methane

9. CASE STUDIES
The following case studies describe two comprehensive
LFG utilization projects initiated by local govern-
ments. Each case study describes how the program was
started, key program activities, and program benefits.
DeKalb County, Georgia—
Seminole Road MSW Landfill
The DeKalb County Sanitation Division is capturing
LFG from the Seminole Road Landfill to generate elec-
tricity and address environmental challenges. Initiated
in 2006, this self-developed project became one of the
first suppliers of green power for the local utility's new
green energy program.
PROGRAM INITIATION
The county commissioners asked DeKalb County of-
ficials to develop a 3.2-MW LFG energy facility, meet
all regulatory requirements, and make it a showcase for
LFG utilization. Additionally, the officials were asked to
complete the project on an accelerated schedule with-
out a third-party developer. Solid waste officials re-
sponded to this challenge, met all criteria, and com-
pleted the project on schedule. Due to an innovative
design, build, and operate procurement approach, the
project was completed seven months after county com-
missioners approved construction (U.S. EPA, 2007c).
Profile: DeKalb County, Georgia
Area: 270 square miles
Population: 750,000
Structure: DeKalb County is governed by seven
elected county commissioners who set policies
and appropriate funding, and an elected chief
executive officer who administers day-to-day
county operations. Management of the Seminole
Road Landfill falls under the auspices of the
County Sanitation Division in the Department of
Public Works.
Program Scope: The Sanitation Division manages
a 3.2-MW LFG electricity generation system
at the Seminole Road Landfill, which contains
approximately 10 million tons of MSW. This
system provides the local utility with more than
22 million kWh of green power annually.
Program Creation: County commissioners
directed the Sanitation Division to request
proposals.
Program Results: The LFG energy project
produces approximately 22.5 million kWh
annually. Environmental benefit of emission
reductions equates to the annual GHG emissions
from 2,800 passenger vehicles.

-------
PROGRAM FEATURES
The LFG energy project at Seminole Road Landfill was
self-developed without the assistance of a third-party
developer and with seamless interface with the existing
flare system and wellfield infrastructure. The project
uses two reciprocating engines with a combined capac-
ity of 3.2 MW to produce electricity from a stream of
captured LFG that reaches approximately 1,100 scfm.
Additional captured LFG is combusted in a flare. The
stream of LFG is produced by approximately 10 million
tons of MSW that have been collected since 1977.
The project includes a contract with a local utility
through which the utility purchases green power pro-
duced from the captured LFG (22.5 million kWh annu-
ally for 10 years). The revenues from the green power
sales will enable the county to recover the $5 million
cost of the system in less than five years. The project
raised $1.9 million in revenue between November 2007
and July 2008.
The showcase energy facility emphasizes education and
offers tours about LFG utilization. The facility offers a
screen where visitors can view real-time performance
of the electricity generators, and displays a full circle
mural that follows trash from its collection to the
landfill to LFG generation, capture, and ultimately to
providing electricity to the same residents and busi-
nesses from which the trash was collected (U.S. EPA,
2007c; 2007d).
PROGRAM RESULTS
In addition to providing a source of green power for
the community (i.e., enough to power 2,000 homes
annually), the program is expected to achieve annual
avoided emissions reductions of approximately 4,000
metric tons of carbon equivalent. Annual emission
reductions are equivalent to the annual GHG emissions
from 2,800 passenger vehicles or CO2 emissions from
34,200 barrels of oil consumed (U.S. EPA, 2007c).

Yancey and Mitchell Counties,
North Carolina—EnergyXchange
Renewable Energy Center
The EnergyXchange is a community-based organiza-
tion in North Carolina that is currently utilizing LFG
to provide energy to on-site glass blowing furnaces, a
pottery kiln, and a greenhouse dedicated to preserving
rare and native flora. The project is unique because it
utilizes LFG from a landfill much smaller than what is
typically considered to be commercially viable.
PROGRAM INITIATION
The project at EnergyXchange was initiated when an
LFG collection system was activated at the nearby
Yancey-Mitchell Landfill. This action galvanized a
community partner, Blue Ridge Resource Conservation
& Development Council, to organize a Landfill
Methane Task Force including more than 140 people
from 40 agencies and organizations. The Task Force
determined the end uses for the LFG, identified oper-
ating partners, engaged local communities in the
project, and identified resources crucial to project
development (U.S. EPA, 2005b).
Profile: Yancey and Mitchell Counties,
North Carolina
Area: Yancey County—313 square miles; Mitchell
County—222 square miles
Population: Yancey County-18,000; Mitchell
County-16,000
Structure: Each county is governed by a board of
elected commissioners. In both counties, these
boards select a county manager to direct day-to-
day operations.
Program Scope: The EnergyXchange Renewable
Energy Center was first developed adjacent to the
Yancey-Mitchell Landfill.
Program Creation: An LFG collection system
developed at the Yancey-Mitchell Landfill led to the
creation of a task force to evaluate opportunities to
use the captured LFG. The EnergyXchange project
was initiated in 1999.
Program Results: Artisans at the EnergyXchange
facilities have saved more than $1 million in
energy costs compared to purchasing energy from
conventional sources. The environmental benefits
of the project are equivalent to the annual GHG
emissions from 800 passenger vehicles.

PROGRAM FEATURES
The EnergyXchange complex, which includes two
craft studios, four greenhouses, three cold frames, a
public gallery, and a visitor center, is located adjacent
to a six-acre landfill and draws on the energy of a 37.5
scfm LFG flow. Water heated by LFG provides heat for
a greenhouse where students learn how to propagate
critical components of local ecosystems. Glass blowers
fine tune their craft over flames fueled by LFG, and
potters fire their wares in an oversized kiln, also fueled
by LFG. In the visitor's center, citizens learn how LFG
energy projects save money and help the environment.
The project showcases community collaboration: in
addition to the Blue Ridge Resource Conservation
& Development Council, other partners include
HandMade in America and Mayland Community
College (EnergyXchange, 2011).
PROGRAM RESULTS
The efforts of EnergyXchange have demonstrated that
LFG energy projects at small landfills can be beneficial
and have shown the power of community partnerships.
The savings to the artisans thus far exceeds $1 million
compared to what they would have paid for traditional
fuel sources. Artisans pay a nominal studio fee to
receive an ample gas supply that is expected to power
them for 15 years (U.S. EPA, 2005b).
The project's environmental benefits include annual
GHG reductions of 1,200 metric tons of carbon
equivalent, which is equal to the carbon sequestered
annually by 900 acres of pine or fir forests, the annual
GHG emissions of 800 passenger vehicles, or the CO2
emissions from 10,300 barrels of oil consumed. Annual
energy savings equate to heating 130 homes (U.S. EPA,
2005b).

the economic feasibility of an LFG enregy project and is available to LMOP
Partners and Endorsers.
LFG Energy Benefits Calculator. This LMOP tool can be used to estimate GHG
emission reductions from LFG energy projects.
Landfill Gas Emissions Model. This model helps estimate emissions rates from
MSW landfills and can be used to estimate total LFG and CH4 generation from a
project.
LMOP Interactive Conversion Tool. This tool can be used to convert LFG-related
statistics (e.g., cubic feet per minute to standard cubic feet per day), and to
estimate LFG energy potential from an MSW landfill.
