1 INTRODUCTION
The Municipality of Anchorage (MOA) has retained EMCON/OWT, Inc. to perform an
economic evaluation of its landfill gas (LFG) beneficial use options. The evaluation is
based on the anticipated LFG recovery rates and considers the cost of design, equipment
procurement, equipment installation, revenue streams, potential government subsidies,
and operations and maintenance (O&M) for the proposed facilities.
This LFG beneficial use study was supported in part by funding from the US Department
of Energy Regional Program Grant No. DE-FG51-02R0211317. This funding does not
constitute any endorsement by the US Department of Energy of the results of the study.
The LFG beneficial use options evaluated for this study are described below. Due to the
poor financial performance of the electrical generation option, two scenarios were
generated. The first electrical generation scenario included costs to construct and
maintain the LFG collection system; the second scenario did not. All of the subsequent
beneficial use options included costs to construct and maintain the LFG collection
system. The Anchorage Regional Landfill is required by Federal New Source
Performance Standards to install and operate such a system.
Due to the difficulty in assessing the value of intangible items such as positive public
relations for the Municipality as a result of using LFG as a beneficial use, these items are
not included in this economic evaluation. The Municipality may want to consider the
value of such intangible items in its final decision to proceed or not proceed with a
project.
1.1 Option 1 – Electricity Generation
Option 1 involves electrical generation with a series of internal combustion engines that
are designed to ignite LFG. Electricity generated by the engines may be sold to a local
utility at its avoided cost rates.
1.2 Option 2 –Transmission of LFG to Enstar Natural Gas
Pipeline
Option 2 includes compression and transmission of LFG into a high-pressure natural gas
pipeline, which runs adjacent to the landfill (990 feet way). Enstar Natural Gas Company
owns the natural gas pipeline. For this option we have reviewed the clean-up
requirements and required operating pressure of the pipeline.
Section 1 – Introduction
1-2
1.3 Option 3 – Transmission of LFG to Eagle River School
Option 3 includes compression of LFG in a low-pressure pipeline and then transmitted
approximately 0.6 miles to the Eagle River School campus for use in its boilers. The
Eagle River School boilers would be modified to allow burning of dual fuels (LFG and
natural gas).
1.4 Option 4 – Transmission of LFG to National Guard
Facilities
Option 4 includes compression of LFG in a low-pressure pipeline and then transmitted
approximately 2.7 miles to the National Guard facilities for use in its boilers. National
Guard boilers would be modified to allow burning of dual fuels (LFG and natural gas).
1.5 Option 5 – Transmission of LFG to Fort Richardson
Facilities
Option 5 includes compression of LFG in a low-pressure pipeline and then transmitted
approximately 5.1 miles to Ft. Richardson for use in its boilers. Ft. Richardson boilers
would be modified to allow burning of dual fuels (LFG and natural gas).
1.6 Option 6 – Transmission of LFG to Existing Municipal Light
& Power (ML&P) Plant (George M. Sullivan No. 2).
Option 6 includes compression of LFG in a low-pressure pipeline and then transmitted
approximately 6.75 miles for use in ML&P’s closest operating electrical plant equipment.
ML&P equipment would be modified to allow burning of dual fuels (LFG and natural
gas).
1.7 Option 7 – Transmission of LFG to Proposed Municipal
Light & Power (ML&P) at Fossil Creek.
Option 7 includes compression of LFG in a low-pressure pipeline and then transmitted
approximately 2.1 miles to the proposed Fossil Creek facility for use in its electrical
generation equipment. ML&P equipment would be modified to allow burning of dual
fuels (LFG and natural gas).
Section 1 – Introduction

1.8 Option 8 – Treatment of Liquid Generated or Collected at
the Anchorage Landfill
Option 8 includes the utilization of LFG to treat liquids generated or collected at the
Anchorage Regional Landfill. These liquids include leachate generated at the landfill and
glycol collected and disposed of by the Municipality. Due to unfavorable preliminary
financial estimates, less detailed discussions of these options are contained in subsequent
sections of this report. .

2 ESTIMATED LANDFILL GAS GENERATION
EMCON/OWT used its proprietary LFG generation model to estimate the quantity of
LFG that will be generated at the Anchorage Regional Landfill.
2.1 Model Input
The LFG model is based on waste inflow, waste composition, waste moisture, and the
potential for air intrusion. The input for the LFG model was determined based on site-
specific data provided by Anchorage Regional Landfill. Assumptions were made based
on EMCON/OWT’s knowledge of the landfill and nationwide studies of municipal solid
waste. The input for the LFG generation model is provided in Appendix 1.
2.2 Model Output
The LFG generation model output is also provided in Appendix 1. The annual utilizable
quantity of LFG (as shown in the LFG generation model output) was used over the 10-
year project life in the economic evaluation. The model output indicates that the average
quantity of LFG generated over the 10-year project life is approximately 1,383 scfm
(Year 1: 1,101 scfm and Year 10: 1,632 scfm). This utilizable quantity of LFG represents
the quantity of LFG expected to be delivered to the blower/flare facility by the LFG
collection and control system over the 10-year project life.
All LFG flow rates quoted above are the expected generation rate. The actual quantity of
LFG that may be available for beneficial use may be slightly less than the reported
generation rates. This reduction of LFG collected versus generated is known as the
“collection efficiency.” Collection efficiency is determined based on LFG well spacing,
cover type, cover maintenance, percent of sideslopes allowing air intrusion, and
maintenance of the LFG collection system. Typical collection efficiencies reported for
geomembrane lined and capped sites are 90 to 95%. Typical collection efficiencies
reported for capped soil and poorly operated LFG collection systems is 60 to 65%. Based
on our review of the plans for LFG collection system design and MOA staff members’
extensive knowledge of LFG design, construction, operations, and their high standards
for each of these disciplines, EMCON/OWT feels a collection efficiency of 75% is very
achievable. Therefore, the model output indicates that the average quantity of collectable
LFG over the 10-year project life is approximately 1,037 scfm (Year No.1: 826 scfm and
Year No. 10: 1,224 scfm).

3 LANDFILL GAS CHARACTERIZATION AND UTILIZATION
3.1 Landfill Gas Characterization and Utilization for Electrical
Generation Equipment
LFG contains many contaminants that have detrimental effects on LFGTE collection,
processing, and distribution equipment. The control of these contaminants can create
secondary air compliance issues related LFGTE plant emissions.
Beside the corrosive properties of LFG caused by contaminants (e.g., hydrogen sulfide,
formation of carbonic acid, etc.,), siloxanes are probably the most troublesome
contaminate for electrical generation equipment. Siloxane testing is now becoming well
known as a primary maintenance and engine performance problem. Siloxane levels can
range from low part per billion by volume (ppbv) levels to several hundred part per
million by volume (ppmv). The reduction of siloxanes to silica dioxide is inevitable as
the gas is burned to produce power and heat.
Siloxanes can cause significant operational problems on LFG utilization projects (e.g.,
microturbines, internal combustion engines, fuel cells, large-scale turbines, catalyst
systems, etc.). The impact of the silica deposition and abrasion is different at every
landfill, but can have a significant maintenance cost impact on equipment.
Most LFGTE projects use internal combustion (IC) engines to generate electricity. The
silica dioxide can reduce head life; plate out and cause bypass of valves, score cylinders
and liners; shorten life of spark plugs; cause increased oil changes; reduce the online
power production time and profit; poison catalyst; produce incomplete combustion
products; and lower engine and/or turbine efficiency.
Having knowledge of all these, EMCON/OWT had the LFG tested for its basic fuel,
volatile organic compounds (VOCs), siloxane, and sulfur components. The results of this
testing are briefly discussed below. The complete laboratory analysis and a possible
“clean-up” process are contained in Appendix 2.
Upon review of data from the samples, it appears this site may be a suitable candidate for
power generation using standard internal combustion (IC) engine technology. Currently,
only the removal of siloxanes should be considered to extend the operational life, reduce
the operational costs, and improve the uptime of the anticipated power generation.
Further testing is recommended after collection wells are installed to check the blend of
fuel components along with VOC and siloxanes.
Section 3 – Landfill Gas Characterization and Utilization

3.2 Landfill Gas Utilization for Boilers
The effects of burning the methane gas recovered from a landfill can be divided into the
following four main categories:
• Effects on boiler efficiency,
• Effect on maximum boiler output capacity or production,
• Effects due to individual compounds in LFG stream, and
• Design changes needed to accommodate using LFG.
3.2.1 Effects on Boiler Efficiency
Typically LFG is introduced into burners that were designed for natural gas having an
energy content of 980 to 1,020 Btu/dscf (dry standard cubic foot). LFG has an energy
content typically of 400 to 600 Btu/dscf. It can be shown by calculation that converting a
boiler from natural gas to LFG will reduce the boiler efficiency by approximately 1%.
This theoretical drop in efficiency is partially offset by a decreased exhaust gas
temperature due to the increased radiative heat transfer coefficient of the combustion
gases due to the increased levels of CO2 in the fuel gas. It should be noted that this
decrease in efficiency is less than the change to other fuels (i.e. changing from #2 fuel oil
to natural gas is a reduction of over 3% in efficiency).
3.2.2 Effect on Maximum Boiler Output Capacity or Production
Because of the lower heating value per cubic foot of LFG, a higher volume of fuel
introduction to the burner is required for equal heat input. Typically twice as many cubic
feet of LFG must be fed as natural gas to get the same Btu input to the burner. The net
effect of this is to increase the total volume of exhaust gas in the stack. This is an
increase of roughly 10% volume flow of gas in the stack. On a boiler where the
combustion air fan is exactly sized for the burner rated input this would have the net
effect of reducing the maximum energy input by 10% when firing LFG. However,
properly sized burners typically have combustion air fans, which are oversized by 20% or
more to account for variations in stack design and installation. In addition, boilers
normally operate at 75% or less of capacity and 100% capacity are only used during
warm-up from light off and this decrease in capacity is usually not detectable in
operation. It should be noted that during the typical boiler tuning the boiler maximum
firing rate is reduced to 85% to 90% of name plate capacity in order to achieve optimal
firing at the lower firing rates. Because the fuel component of both LFG and natural gas
is methane the amount of combustion air required to burn 1 MMBtu of methane gas is
equal to the amount required to burn 1 MCF of natural gas (natural gas is measured in
Section 3 – Landfill Gas Characterization and Utilization
3-3
MCF or thousand cubic feet which at 1,000 Btu/cf by specification gives 1 MCF = 1
MMBtu) so that there is no net increase in combustion air required when changing fuels
for equal heat input.
3.2.3 Effects Due to Individual Compounds in LFG Stream
The major components of LFG are methane (CH4), carbon dioxide (CO2), nitrogen (N2),
oxygen (O2) and other trace components primarily water vapor (H2O), non-methane
organic compounds (NMOCs), hydrogen sulfide (H2S), and siloxane (SiOx).
Methane is the primary energy component of LFG and is consumed during the
combustion process. The combustion process is carefully regulated and is required to be
controlled in such a manner that combustion products such as carbon monoxide (CO),
nitrous oxides (NOx), and unburned hydrocarbons (CH4 and NMOC) are minimized.
A major environmental benefit of burning LFG is that methane when released into the
atmosphere is 21 times more effective at heat retention that carbon dioxide or in other
words burning the methane contained in LFG has a net effect of reducing the total amount
of greenhouse gases released from a landfill by a factor of 20. It is recognized by the US
EPA that for each 1 MMBtu of LFG that is burned and not released from the landfill there
is a net reduction of 1 ton of equivalent CO2 released into the atmosphere. In a typical
large project this reduction will be in the hundreds of thousands of tons of CO2
reductions per year.
The carbon dioxide and nitrogen in the gas stream are inert and have no effect on the
combustion process other than to:
(i) cool the theoretical flame temperature thereby decreasing efficiency as
described above, and;
(ii) increase the total volume of exhaust gases, which must be removed by the
combustion air fan thereby decreasing maximum input as described above.
(2) It is important to note that the nitrogen in the fuel gas stream is not the same as
what is commonly referred to as fuel born nitrogen, which is typically found in
both liquid and solid fuels in the form of nitrates. In those cases the fuel bound
nitrogen will add to the total NOx production of the boiler. Because the nitrogen
in the fuel stream is non-reactive as well as the carbon dioxide they both act to
reduce the flame temperature, which has the net effect of reducing the amount of
prompt NOx formed in the combustion process. Burner manufacturers such as
COEN document a total NOx reduction of up to 30% when burning LFG versus
natural gas. This reduction is due to the cooler flame temperatures in the
combustion zone, which has the same effect as flue gas recirculation (FGR)
without the performance and maintenance penalties associated with FGR.
Section 3 – Landfill Gas Characterization and Utilization
3-4
(3) Because of the nature of gas recovery at a landfill there is always trace amounts of
water vapor present (from 0.3% to 3% by volume) in the fuel gas stream. While
the water has no effect on combustion and is negligible when compared to the
approximately 15% water vapor present in the exhaust gas due to the combustion
of the hydrogen component of the methane contained in the LFG there is no net
effect on the boiler proper. However, care must be taken to prevent water
accumulation in the gas delivery piping and gas train especially when this piping
is located out of doors in cold environments.
(4) In the gas stream from a typical landfill there are varying amounts of NMOCs,
which can vary from as little as 100 ppmv to over 2,000 ppmv. Since all the
species that may be found in LFG are hydrocarbons they are nearly completely
destroyed in the combustion process. There are no significant detrimental effects
due to the presence of NMOCs in the LFG stream.
(5) Hydrogen sulfide (H2S) is another trace compound, which is typically found in
LFG and is a poisonous gas at elevated concentrations. Typical levels of H2S in
methane gas streams are close to 10 ppmv, which is high enough to be detectable
by its distinct sour (rotten egg) odor. Typical natural gas has up to 3 ppmv of H2S,
which puts both fuels on roughly equal footing as to the potential for harm. H2S is
converted to SO2 during the combustion process.
(6) Siloxane often is found in LFG and can vary from a few parts per billion to many
parts per million. Siloxane is a gas that contains bound silicon. Upon reaching
typical combustion temperatures it is converted into silicon dioxide, which forms
a very light non-toxic dust that typically passes through the boiler. In most
applications small accumulations of this dust are removed annually and disposed
of. The only problems noted with this dust are on boilers with serrated fin or tight
spaced fin economizers, which act as particulate filters and can become plugged
with the silica dust. The silica dust does not adhere to most surfaces and is
removed by light brushing or air pressure. Economizers with wide fin spacing
(i.e. less than 3 fins per inch) typically do not plug with the silica dust.
3.2.4 Design changes needed to accommodate using LFG
In most situations LFG will be introduced to a boiler that already exists. The following
are design changes or modifications that should be examined. Not all of these will be
required on any given installation and it is possible that very minimal modifications will
be required. When new equipment is purchased to burn LFG, the manufacturer will be
responsible for the required design to adequately burn LFG. It should be noted that the
following assume that the LFG is being used in a existing gaseous fuel (typically natural
gas) fired boiler or process burner, in cases where the burner is used with liquid or solid
Section 3 – Landfill Gas Characterization and Utilization
3-5
fuels then the manufacturer of the burner should be contacted for specific
recommendations.
(1) Because of the increased volume of fuel required to match energy input,
LFG is normally introduced into an existing burner through a separate gas
train with separate modulating gas control valve. Typically, if the same
burner ring is to be used then the feed pressure of the gas to the ring is
increased a factor of 1.5 to 4 times that of natural gas.
(2) Since the energy content of LFG can vary by as much as 20%, an oxygen
trim system should be considered for larger (over 10 MMBtu/hr input)
burners and boilers. In these larger installations the increase in efficiency
due to oxygen trim will normally pay for itself in less than a year due to
increased boiler efficiency.
(3) Installations where there is less LFG available than the maximum required
input of the boiler, a co-fire system can be employed. Co-fire systems
have oxygen trim and will allow for maximum consumption of LFG while
allowing for the boiler to reach full fire when needed.
(4) In installation where continuity of service is desired, minimal control
modifications can be made so that loss of LFG availability will cause an
automatic transfer to natural gas or other back up fuel.
(5) In some burners (particularly larger or liquid fueled burners), a new gas-
firing ring will need to be added specifically for LFG.
(6) On newer installations, many manufacturers have experience with burning
LFG due to its similarity to sewage treatment plant digester gas. Most
boiler manufacturers have an existing design for digester gas. Digester gas
differs from LFG only in its much higher concentration of H2S.
(7) Typically the pilot will continue to be fired with natural gas. In
installations where LFG is the only fuel a propane pilot is normally used.
The preceding is intended as guides to use in evaluating the potential use of LFG as a fuel
and not as specific design recommendations. At this time, no “clean up” for the boiler
fuel application is being considered. A qualified engineer should be employed on any
project to insure the safe and successful use of LFG as an alternative fuel.

4 POTENTIAL LFGTE PROJECT SUBSIDIES
As part of this study EMCON/OWT researched the availability of governmental subsidies
that exist to help offset the cost of LFGTE system development. A list of the potential
subsidies that were researched is provided below.
4.1 Federal Renewable Energy Tax Credits
Federal Renewable Energy Tax Credits, also known as “Section 29 tax credits,” are not
available at this time. In the past, tax credits were available for projects that used landfill
gas as a fuel. Credits that were beneficial to tax payers were valued at $1.00. Landfill
gas equivalent to 1 million Btus was one credit. For comparison purposes, the past
program (expiring) values the credit at $1.059 per million Btu. Federal legislation will be
necessary for this program to become available again. Whether or not such legislation
passes in 2004 is speculative at best given the political situation and the upcoming
presidential election.
The 108th Congress debated energy bill legislation without success. Whether or not an
energy bill passes in 2004 is debatable and what the bill will contain is, again,
speculative. The bill that was progressing in 2003 valued landfill gas as a tax credit; the
suggested value was $3 per barrel of oil equivalent. This made the tax credit associated
with landfill gas used in an energy project at $0.50 per million Btu. The bill also limited
the amount of LFG that can be used to create a tax credit to only 200,000 ft cubed per
day.
4.2 Renewable Energy Production Incentive (REPI)
REPI funds are available to help subsidize LFGTE development costs for entities that are
not typically eligible for tax credits (e.g., public agencies such as the Municipality of
Anchorage). Since its inception, REPI funds have designated LFG as a second tier
renewable energy. Renewable energy sources, such as wind power, are given a higher
priority when distributing funds. Second tier energy sources receive funds only after the
available funds are distributed to higher tier renewable energy sources. While LFG
projects have received REPI funds in the past, EMCON/OWT has not included this
subsidy in the financial pro forma contained in subsequent sections. If the MOA does
develop the LFGTE project using internal funds, annual REPI applications should be
submitted.
Section 3 – Potential LFGTE Project Subsidies

4.3 Discussion of Potential Valuable Landfill Gas Attributes
This brief discussion is included to demonstrate that the attributes associated with landfill
gas can be a valuable asset to the owner. Any activity associated with a landfill and its
landfill gas should be undertaken with this knowledge. Any decisions should take into
account the current situation as it relates to the attributes discussed below. The situation
may change in the near future due to local, regional, national, and international politics.
4.3.1 Valuable Attributes of Landfill Gas
Landfill gas is a valuable commodity due to its source, municipal solid waste, and its
main constituent, methane. LFG is recognized as a renewable energy by the US DOE,
USEPA, most state energy programs, and the international bodies working to control
global warming. Electricity produced from LFG or beneficial use of the LFG can be a
source of credit that can have many values. While the areas for credit or value are still
developing across the United States and around the world, the following discussion will
assist the Municipality of Anchorage in understanding the value of these attributes and
will suggest approaches for how to proceed.
4.3.2 Renewable Energy Credits
A Renewable Energy Credit (REC) is an attribute that is given to landfill gas by those
states that have legislated renewable portfolio standards (RPS). Generally, electricity
produced by LFG is considered to have an ancillary REC attribute due to the avoided use
of fossil fuel. For each megawatt of electricity produced from LFG, one REC unit is
produced. States that have legislated a RPS generally allow RECs from LFG projects to
be used to attain compliance with the mandated portfolio standard. A portfolio standard
generally requires a pre-established percentage of energy produced from renewable
sources be sold by the power suppliers.
Electricity suppliers attain compliance with the mandated RPS through free-market
purchase of RECs from generators, who are sometimes referred to as Qualified Facilities.
RECs have been purchased for $4.50 to $40.00 per REC in Massachusetts, New Jersey,
and most recently Connecticut. Recent discussions (January 2004) with environmental
REC brokers reveal a weak market for RECs in areas not required to utilize them, such as
Alaska. The price suggested was $1.00 per REC for these “weak” areas.
RECs may be sold and “wheeled” to other states from non-RPS states1.2. These “deals”
are not lucrative at this time, with potential prices in the range of $1 to $2 per REC. This

Section 3 – Potential LFGTE Project Subsidies
4-3
is due to the voluntary market in states with no requirement to supply RECs in their
electricity portfolios. Buyers may be difficult to identify. According to one broker, the
market is probably oversold. It does show, however, that a national market is emerging.
4.4 Greenhouse Gas Credit Values
While there are few regulatory drivers in the United States for a greenhouse gas (GHG)
credit market, there is a great deal of activity at the state level to develop mandatory
carbon dioxide reduction programs. There are few regulatory requirements for utilities,
industries, and businesses to reduce their GHG emissions; therefore, there is currently
little incentive to purchase GHG offsets.
Some trades of CO2E (calculated on a CO2 equivalent basis) have taken place despite the
negative situation relative to required CO2 reductions. Companies will occasionally need
CO2E offsets. Oregon and Massachusetts have requirements for new energy producers to
offset some or all of their CO2 emissions. LFG has played a role in at least one of these
situations in the Commonwealth of Massachusetts. The Energy Facility Siting Council
(of Massachusetts) required Mirant Energy to pay $300,000 for CO2E credits for
reconstruction of a power plant.
Greenhouse gas credits are the attributes assigned by climate change programs to the
reductions in GHG emissions that are above the required levels, if any. Projects
undertaken to reduce GHG gasses qualify as GHG credits. They are generally referred to
as carbon dioxide equivalents or CO2E. The issue of whether or not the landfill is
required to control the landfill gas is very important to the creation of credits. Landfills
that are required to reduce the LFG may not have any credits available due to the
additionally3 requirement.
Discussions regarding GHG or climate change are occurring across this country. Most
state programs, such as those found in Oregon, Massachusetts, California, Connecticut,
and New Hampshire, see the need for a federal program with widespread inter-sector
trading of CO2E. This bodes well for existing and future LFG-to-energy projects. The
project owner should have the mechanisms in place to properly track and document the
LFG used and credits generated. The US Department of Energy (DOE) 1605B program
is an excellent way to start this process. The program is currently being improved to
ensure better information and that CO2E credits are registered. The revisions will be in
place within the year. DOE’s program requires gas measurement, gas generation
documentation, and equipment calibration. Regular data collection from the project

3 Additionally: Kyoto protocol and other protocols such as the World Resource Institute and World
Business Council for Sustainable Development will not allow credits from projects.
Section 3 – Potential LFGTE Project Subsidies

should be collected and maintained. As the data is filed with DOE, the credits will be
available for others to view and perhaps acquire.
At a recent SWANA LFG conference in San Antonio, Texas, Carl Bartone, a World Bank
Environmental Consultant, described his work in developing LFG to Energy projects in
Central and South America. He also described the value of the CO2E that will be the
commodity traded in the GHG arena. Bartone reports that the cost of producing a CO2E
is in the range of $3 to $4 per TCO2E from the Prototype Carbon Fund (PCF) data. He
also reports that in a 2002 report, the PCF has suggested that the marginal cost of
compliance with CO2 reductions is on the order of $15 per TCO2E. The consensus of
experts around the world is that LFG is a valuable commodity to be tracked and
documented in order to obtain the value of the credits as programs develop.
4.5 Trading Brokers
There are many traders that can handle the sale or transfer of LFG energy project
attributes. Evolution Markets, Cantor-Fitzgerald, and Natsource are among them. As the
project develops, the brokers should be made aware of the project details and schedule.
They may be able to place sales or commitments in advance with additional revenue for
the project. EMCON/OWT can prepare the introductions and information necessary for
the brokers to understand the project. Additional information on their services may be
found at the following web sites:

The following assumptions have been made for the purpose of comparing each of the
beneficial use options:
• The project pro forma period of 10 years (2006-2015) is commonly used for
landfill gas to energy financial feasibility analysis. As analysis periods go to 15
years or longer, there is greater uncertainty inherent in making financial
predictions that far into the future. Also, Internal Revenue Service depreciation
tables allowed owners to use 10-year depreciation for tax purposes and this further
supported 10 years as an industry practice. It must be noted that the equipment,
with proper maintenances, may be fully operable for longer periods. The pro
formas include the depreciation methods and lives as outlined in GASB 34
(government accounting standards). The Summary page of each pro forma
includes the basic MUSA and depreciation assumptions and the 10-year total
MUSA contribution.
• An annual inflation rate of 2 percent
• Financial pro formas were developed at a breakeven or slight positive cash flow,
as MOA wishes to encourage the beneficial use of LFG generated at its landfill.
• Since the Municipal Utility Service Assessment that applies to Enterprise Fund
entities (such as the landfill), the pro formas incorporate the asset net book value
based millage rate (16 mils) and the revenue based 1.25% contribution.
• Two scenarios were analyzed for electrical generation. One of the scenarios
excludes costs to design, permit, construct, operate, and maintain the LFG
collection system, and the other includes these costs. All subsequent options
include the costs to design, permit, construct, operate, and maintain the LFG
collection system.
• Project financing, permitting, and construction will occur during 2005. Actual
beneficial use revenues will begin on January 1, 2006.
Production, capital, revenue, and O&M cost assumptions are provided for each of these
options in the following sections.
Section 4 – Economic Analysis
5-2
5.2 Option 1 – Electricity Generation
To determine the economic feasibility of an electrical generation plant at the Anchorage
Regional Landfill, the number of engines that could be brought on-line at the site is first
determined. For this facility we recommend using Caterpillar engine/generator sets,
primarily because the landfill operations already use a significant amount of CAT
equipment and also because CAT engines have a good history of performance with LFG.
Based on the requirements of CAT G3516LE engines, a total of three engines could
initially be brought into service for electrical generation. Three engines require
approximately 918 scfm of LFG at a 50% methane concentration and will generate a
gross 804 kW each. An additional generator can be brought on-line for every 306 scfm of
LFG extracted. The decision to bring more generators on-line can be made at a later date.
Capital and O&M costs for the engines are based on the utilization of three engines to
produce electricity. As shown in the financial pro-forma statement for this option (see
Appendix 3), the electricity sold by three CAT G3516LE engines is 195,070-megawatt
hours from 2006 to 2015 assuming 95% on-line and 3% plant loads are used by the plant.
It is assumed that the electricity generated will be sold to a local utility.
Utility deregulation is not currently available in Alaska; therefore, power must be sold to
local utilities. If enacted, deregulation will allow retail wheeling of your power on local
utility distribution lines. This allows you to sign up customers (through a licensed power
broker) and sell power to them instead of the customers purchasing the power from local
utilities. The idea of wheeling is to provide power to a customer at a lower cost than the
utilities, but at a higher rate than they would receive if you had an avoided cost contract.
The power lines directly adjacent to the Anchorage Regional Landfill are owned by
Matanuska Electric Association (MEA). However, MEA is contractually obligated to
buy all of its power from Chugach Electric until 2014. Currently, MEA purchases power
at a rate of 5.9 cents per kWh (average avoided cost of electrical generation and
transmission). Based on recent discussions with Chugach Power (Peter Poray), they have
verbally quoted an average electrical generation avoided cost of 4.2-cents per kWh.
However, Chugach is only willing to sign new power purchase agreements (PPA) in the
3-cent per kWh range. The avoided cost provided above may vary over the next several
years, thereby affecting the economic analysis.
Since power cannot be sold directly to MEA, power must be wheeled to Chugach using
MEA power lines. Wheeling charges for the pro formas contained in Appendix 3 assume
a wheeling rate of $0.005/kWh and an interconnection cost of $250,000.
With three CAT generators operating at 95% availability and 3% plant loads,
approximately 20.07 million kWh will be available for sale each year. During the years
2006 through 2008 it is expected that gas availability will result in slightly lower
production rates of 17.1 to 19.2 million kWh until the landfill’s gas recovery rate is
Section 4 – Economic Analysis
5-3
sufficient for full loading of the engine. As directed by MOA staff, we have developed
our pro formas on a breakeven basis. The breakeven point for the scenario that includes
GCCS construction and operations is 5.47 cents per kWh. The breakeven point for the
scenario excluding GCCS construction and operations is 4.81 cents per kWh.
In order for the MOA to sell wholesale or retail power it will need licensing as a qualified
facility (QF) by the Federal Energy Regulatory Commission (FERC). QF applications are
typically prepared for all LFG-to-Energy projects. Having QF status forces the local
utility to purchase excessive power generated but not sold to a retail customer at avoided
rates.
5.2.1 Option 1A – Electrical Generation Using Engine Generator Sets
Including Costs of Gas Collection System Installation and Annual O&M
Expenses
1. LFG VOLUMES – The project consists of three CAT Triton Powerpacks with
CAT 3516LE engines. Fuel requirements are 306 scfm (50% methane content)
per engine. Initial recoverable gas is estimated at 826 scfm, which will result in
slightly reduced kWh output; however, by 2009 the engines will have sufficient
fuel for full load operation. Future gas recovery estimates indicate that additional
engine generator sets could be added, however, our pro forma is based on three
units throughout the project life.
2. REVENUES – Based on the projected power generation, 195.07 million kWhs
could be sold over the next 10 years. To break even or produce a slight positive
cash flow (including wellfield construction and O&M costs) will require a power
sales rate of 5.47 cent per kWh, escalated 1% per year. At this rate, the
anticipated revenue for the ten-year period will be $11,176,000.
3. CAPITAL COSTS – The capital cost to construct the wellfield, generation
equipment, gas processing equipment and, interconnect with utility transmission
grid will be approximately $4,109,000.
4. O&M COSTS – The O&M costs inclusive of the wellfield, generation
equipment, gas processing, and interconnect, as well as general and administrative
costs, are projected to be $6,327,000 over the 10-year project life.
5. SUMMARY – Over the 10-year project life, the expected revenues at a sale price
of 5.47 cents per kWh will be $11,176,000. Over the same time period, the
projected expenses, including cost of ownership, will be $10,860,000.
Section 4 – Economic Analysis
5-4
5.2.2 Option 1A – Electrical Generation Using Engine Generator Sets
Excluding Costs of Gas Collection System Installation and Annual O&M
Expenses
1. LFG VOLUMES – No change.
2. REVENUES – Based on the projected power generation, 195.07 million kWhs
could be sold over the next 10 years. To break even or produce a slight positive
cash flow (including wellfield construction and O&M costs) will require a power
sales rate of 4.81 cent per kWh, escalated 1% per year. At this rate, the
anticipated revenue for the ten-year period will be $9,827,000.
3. CAPITAL COSTS – The capital cost to construct the wellfield, generation
equipment, gas processing equipment, and interconnect with utility transmission
grid will be approximately $3,207,000.
4. O&M COSTS – The O&M costs inclusive of the wellfield, generation
equipment, gas processing, and interconnect, as well as general and administrative
costs, are projected to be $6,048,000 over the 10-year project life.
5. SUMMARY – Over the 10-year project life, the expected revenues at a sale price
of 4.81 cents per kWh will be $9,827,000. Over the same time period, the
projected expenses, including cost of ownership, will be $9,584,000.
5.3 Option 2 – Transmission of LFG to Enstar Natural Gas
Pipeline
An Enstar Natural Gas Company pipeline exists approximately 990 feet east of the
proposed blower and flare station location. A topographic map is provided in Appendix 4
that displays the pipe routing and tie-in location for this option. A cross-section of this
pipe routing is also contained in the same appendix.
Based on discussions with Mr. Andrew D. White of Enstar, this natural gas pipeline
operates at a maximum of 900-psig pressure. Mr. White also indicated that it is Enstar’s
policy to only accept gas into its system that has a heating value of approximately 1,000
Btu’s per cubic foot. Since raw LFG typically has a heating value of 400 to 550 Btu/cf,
cleaning up the MOA LFG to remove carbon dioxide and air will be required.
A financial pro forma was calculated using industry-accepted figures (see Appendix 5).
For this scenario, it was assumed that this end user could utilize all generated LFG.
Results of this estimate indicate the following:
Section 4 – Economic Analysis
5-5
1. LFG VOLUMES – For the year 2006, the projected flow of LFG recovered is
826 scfm or 209,000 mmBtus. After clean up of the gas, only 160,000 mmBtus
(77% conversion to saleable Btu’s) will be available for injection into the
pipeline.
2. REVENUES – Based on the projected flows per year, assuming a 95% utilization
factor and 77% conversion to saleable Btu’s, 2,009,000 mmBtus could be
recovered and processed for sale over the next 10 years. To break even or
produce a slight positive cash flow (including wellfield construction and O&M
costs) will require a sales price of $4.32 per mmBtu, escalated 2% per year. At
this price, the anticipated revenue for the ten-year period will be $9,571,094.
3. CAPITAL COSTS – The capital cost to construct the wellfield, pipeline (990
feet), purchase compressors, and cleanup equipment will be approximately
$2,995,000.
4. O&M COSTS – The O&M costs inclusive of the wellfield, pipeline, compressor,
cleanup equipment, and electrical, as well as general and administrative costs, are
projected to be $5,605,654 over the 10-year project life.
5. SUMMARY – Over the 10-year project life, the expected revenues at a sale price
of $4.32 will be $9,571,094. Over the same time period, the projected expenses,
including cost of ownership, will be $8,935,635.
Further evaluation of this beneficial use option appears to be unnecessary. The primary
reasons this option is not economically feasible are as follows:
1 Enstar requires “clean up” of the LFG. This adds significant capital and O&M
costs.
2. The existing Enstar line is operated at a maximum of 900-psig pressure.
Compression of gas to 900 psig adds significant capital and takes a significant
amount of electric power.
5.4 Option 3 - Transmission of LFG to Eagle River School
An economic analysis was performed to determine the feasibility of constructing a
pipeline to the Eagle River School and transporting LFG to the site for use in its boilers.
The proposed boiler specifications for Eagle River School are provided in Appendix 6. A
topographic map is provided in Appendix 7 that displays the pipe routing and tie-in
location for this option. A cross-section of this pipe routing is also contained in the same
appendix. Initial discussions with the School District were very encouraging, and they
are open to the idea of utilizing LFG. However, after further analysis, the school would
only utilize a small portion of the available LFG.
Section 4 – Economic Analysis
5-6
A detailed economic analysis for this scenario was calculated using industry-accepted
figures (see Appendix 8). Results of this financial pro forma indicate the following:
1. LFG VOLUMES – Based on the past consumption of LFG at a similar existing
school in the area, Eagle River School is anticipated to require an estimated flow
of 105 scfm at 50% methane.
2. REVENUES – Based on the projected demand per year, 265,420 mmBtus could
be sold over the next 10 years. To break even or produce a slight positive cash
flow (including wellfield construction and O&M costs) will require a sales price
of $18.87 per mmBtu, escalated 2% per year. At this price, the anticipated
revenue for the ten-year period will be $5,484,108.
3. CAPITAL COSTS – The capital cost to construct the wellfield, pipeline (2.0797
miles), purchase compressors, and end user upgrades will be approximately
$2,186,000.
4. O&M COSTS – The O&M costs inclusive of the wellfield, pipeline, and
compressor, and electrical as well as general and administrative costs, are
projected to be $2,653,798 over the 10-year project life.
5. SUMMARY – Over the 10-year project life, the expected revenues at a sales
price of $18.87 will be $5,484,108. Over the same time period, the projected
expenses, including cost of ownership, will be $5,085,151.
Further evaluation of this beneficial use option appears to be unnecessary. The primary
reasons this option is not economically feasible are as follows:
1. Eagle Valley School gas demand is too low and is not consistent throughout the
year. Most of the demand is during the winter months. This condition does not
generate enough cash to offset capital and O&M costs.
2. The length of the pipeline is too long to justify the small amount of gas demanded.
This adds significant capital costs
5.5 Option 4 – Transmission of LFG to National Guard
An economic analysis was performed to determine the feasibility of constructing a
pipeline to the National Guard facilities and transporting LFG to the site for use in its
boilers. A topographic map is provided in Appendix 9 that displays the pipe routing
and tie-in location for this option. A cross-section of this pipe routing is also
contained in the same appendix. Initial discussions with the National Guard were
very encouraging, and they are open to the idea of utilizing LFG. Natural gas
consumption, equipment make and model numbers, etc., provided by the National
Section 4 – Economic Analysis
5-7
Guard revealed that only a few pieces of equipment are suitable for conversion to
utilize LFG (i.e., four Weil-McLain Boilers that use Gordon Piatt Burners). Because
of this, the demand for LFG during warmer months of the year is substantially below
the LFG production rate. A detailed economic analysis for this scenario was
calculated using industry-accepted figures (see Appendix 10). For this scenario, it was
assumed only a portion of the generated LFG could be utilized by the National Guard.
Results of this financial pro forma indicate the following:
1. LFG VOLUMES – For the year 2006, the projected flow of LFG recovered is
826 scfm. However, the National Guard Armory's seasonal gas demand is such
that the Armory annual usage of LFG would be approximately 650 scfm.
2. REVENUES – Based on the projected flows per year assuming a 95% utilization
factor, 1,643,000 mmBtus could be recovered for sale over the next 10 years. To
break even or produce a slight positive cash flow (including wellfield construction
and O&M costs) will required a sales price of $3.45 per mmBtu, escalated 2% per
year. At this price, the anticipated revenue for the ten-year period will be
$6,198,000.
3. CAPITAL COSTS – The capital cost to construct the wellfield, pipeline (2.734
miles), purchase compressors, and end user upgrades will be approximately
$2,492,000.
4. O&M COSTS – The O&M costs inclusive of the wellfield, pipeline, and
compressor, and electrical as well as general and administrative costs, are
projected to be $2,969,000 over the 10-year project life.
5. SUMMARY – Over the 10-year project life, the expected revenues at a sales
price of $3.45 will be $6,198,000. Over the same time period, the projected
expenses, including cost of ownership, will be $5,742,000.
5.6 Option 5 – Transmission of LFG to Fort Richardson
An economic analysis was performed to determine the feasibility of constructing a
pipeline to Fort Richardson and transporting LFG to the site for use in its boilers. A
topographic map is provided in Appendix 11 that displays the pipe routing and tie-in
location for this option. A cross-section of this pipe routing is also contained in the same
appendix.
Initial discussions with Ft. Richardson were very encouraging, and they are open to the
idea of utilizing LFG. The natural gas demand for Ft. Richardson vastly exceeds the
generation rate of LFG from the Anchorage Regional Landfill. A listing of the over 500
natural gas burning pieces of equipment (shown in Appendix 11) was provided by Ft.
Section 4 – Economic Analysis
5-8
Richardson staff (Debra S. Breindel). Of these nearly 500 pieces of equipment, 4 large
Cleave-Brooks boilers appear to be best suited for conversion to operate on LFG.
Cleaver-Brooks boilers have a good history of being converted to LFG use, and the ones
at Ft. Richardson are located in one single location (Building No. 726). This single high
gas demand location is ideal for LFG utilization and eliminates the need for elaborate and
costly gas delivery infrastructure.
A detailed economic analysis for this scenario was calculated using industry-accepted
figures (see Appendix 13). For this scenario, it was assumed that this end user could
utilize all the generated LFG. Results of this financial pro forma indicate the following:
1. LFG VOLUMES – For the year 2006, the projected flow of LFG recovered is
826 scfm. It is assumed that Fort Richardson Building #726 would use all
available gas.
2. REVENUES – Based on the projected flows per year, assuming a 95% utilization
factor, 2,620,000 mmBtus could be recovered for sale over the next 10 years. To
break even or produce a slight positive cash flow (including wellfield construction
and O&M costs) will require a sales price of $2.72 per mmBtu, escalated 2% per
year. At this price, the anticipated revenue for the ten-year period will be
$7,861,211.
3. CAPITAL COSTS – The capital cost to construct the wellfield, pipeline (5.1454
miles), purchase compressors, and end user upgrades will be approximately
$3,256,000.
4. O&M COSTS – The O&M costs inclusive of the wellfield, pipeline, and
compressor, and electrical as well as general and administrative costs, are
projected to be $3,564,149 over the 10-year project life.
5. SUMMARY – Over the 10-year project life, the expected revenues at a sales
price of $2.72 will be $7,861,211. Over the same time period, the projected
expenses, including cost of ownership, will be $7,189,410.
5.7 Option 6 – Transmission of LFG to Existing ML&P Facility
(George M. Sullivan Power Plant No. 2)
An economic analysis was performed to determine the feasibility of constructing a
pipeline to the nearest existing ML&P facility and transporting LFG to the site for use in
its natural gas burning equipment (boilers, gas turbines, etc.). A topographic map is
provided in Appendix 14 that displays the pipe routing and tie-in location for this option.
A cross-section of this pipe routing is also contained in the same appendix. Initial
discussions with ML&P were encouraging, and they are open to the idea of utilizing LFG.
Section 4 – Economic Analysis
5-9
However, after further analysis, the nearest plant was determined to be over six miles
away.
It is preferred that a low-pressure piece of equipment be utilized for the LFG delivered to
this power plant. Preliminary discussions with ML&P staff indicated that a low-pressure
end use could most likely be identified. If a low-pressure piece of equipment is not
available and a high-pressure application is required to be utilized, the cost of
pressurization will substantially increase capital expenditures. For this option, it was
assumed a low pressure could be identified.
A detailed economic analysis for this scenario was calculated using industry-accepted
figures (see Appendix 15). For this scenario, it was assumed that this end user could
utilize all the generated LFG. Results of this financial pro forma indicate the following:
1. LFG VOLUMES – For the year 2006, the projected flow of LFG recovered is
826 scfm. It is assumed that the George M. Sullivan Power Plant would use all
available gas.
2. REVENUES – Based on the projected flows per year, assuming a 95% utilization
factor, 2,620,000 mmBtus could be recovered for sale over the next 10 years. To
break even or produce a slight positive cash flow (including wellfield construction
and O&M costs) will require a sales price of $2.86 per mmBtu, escalated 2% per
year. At this price, the anticipated revenue for the ten-year period will be
$8,256,531.
3. CAPITAL COSTS – The capital cost to construct the wellfield, pipeline (6
miles), purchase compressors, and end user upgrades will be approximately
$3,527,000.
4. O&M COSTS – The O&M costs inclusive of the wellfield, pipeline, and
compressor, and electrical as well as general and administrative costs, are
projected to be $3,598,169 over the 10-year project life.
5. SUMMARY – Over the 10-year project life, the expected revenues at a sales
price of $2.86 will be $8,256,531. Over the same time period, the projected
expenses, including cost of ownership, will be $7,522,934.
5.8 Option 7 – Transmission of LFG to Proposed ML&P Facility
(Fossil Creek Power Plant)
An economic analysis was performed to determine the feasibility of constructing a
pipeline to a ML&P proposed facility at Fossil Creek and transporting LFG to the site for
use in its electrical generating equipment. A topographic map is provided in Appendix
Section 4 – Economic Analysis
5-10
16 that displays the pipe routing and tie-in location for this option. A cross-section of this
pipe routing is also contained in this same appendix. Initial discussions were held with
ML&P, and they are very open to the idea of utilizing LFG because they could
incorporate LFG use into their design. Again, it was assumed a low-pressure application
could be identified for the proposed power plant. If a low-pressure piece of equipment is
not available and a high-pressure application is required to be utilized, the cost of
pressurization will substantially increase capital expenditures.
A detailed economic analysis for this scenario was calculated using industry-accepted
figures (see Appendix 17). For this scenario, it was assumed that this end user could
utilize all the generated LFG. Results of this financial pro forma indicate the following:
1. LFG VOLUMES – For the year 2006, the projected flow of LFG recovered is
826 scfm. It is assumed that the proposed Fossil Creek Power Plant would use all
available gas.
2. REVENUES – Based on the projected flows per year, assuming a 95% utilization
factor, 2,620,000 mmBtus could be recovered for sale over the next 10 years. To
break even or produce a slight positive cash flow (including wellfield construction
and O&M costs) will require a sales price of $2.14 per mmBtu, escalated 2% per
year. At this price, the anticipated revenue for the ten-year period would be
$6,194,794.
3. CAPITAL COSTS – The capital cost to construct the wellfield, pipeline (2.0797
miles), purchase compressors, and end user upgrades will be approximately
$2,285,000.
4. O&M COSTS – The O&M costs inclusive of the wellfield, pipeline, and
compressor, and electrical as well as general and administrative costs, are
projected to be $3,165,628 over the 10-year project life.
5. SUMMARY – Over the 10-year project life, the expected revenues at a sales
price of $2.14 will be $. Over the same time period, the projected expenses,
including cost of ownership, will be $5,713,379.
5.9 Option 8- Treatment of Liquid Generated or Collected at the
Anchorage Regional Landfill
5.9.1 Leachate Evaporation Using LFG
Leachate generated by the landfill is currently accumulated by a collection system and
transported to an off-site wastewater treatment plant owned and operated by the
Section 4 – Economic Analysis
5-11
Municipality of Anchorage. Leachate evaporation utilizing LFG has been conducted as
part of this study to enable the Municipality to compare the evaporation costs to its
current disposal costs.
Option 8 involves disposing of leachate by the proposed flare facility to incorporate
EMCON/OWT’s patented Leachate Evaporator (E-Vap). The E-Vap evaporates leachate
and the off vapors are destroyed in an enclosed flare, thus eliminating the need for
complex treatment of leachate.
Prior to performing a detailed economic analysis of this option, a rough estimate was
calculated using industry-accepted figures. The results of this rough estimate determined
the following:
1. On average, the leachate collection system at the Anchorage Regional Landfill has
collected approximately 7,000,000 gallons per year since 1990.Pending
implementation of design changes currently under consideration (including
complete recirculation) may significantly reduce this volume.
2. Collection, transport, and disposal costs are limited to transportation and are in the
range of 2 to 3 cents per gallon.
3. Typical costs for treatment of collected leachate by our patented E-Vap
technology are higher than 3 cents per gallon.
Based on current leachate collection rates, a 20,000-gpd-leachate evaporator would be
needed. Recent pro forma for this size unit (with a flare) indicated a disposal cost of
approximately 6.8 cents per gallon. Again, the landfill is currently hauling leachate to the
city sewage treatment plant for a cost of less than 3 cents for trucking and no cost from
the treatment plant. Therefore, further evaluation of this beneficial use option appears to
be unnecessary.
5.9.2 Glycol Recycling Using LFG
At the request of the MOA, EMCON/OWT has briefly reviewed the feasibility of
utilizing LFG to recycle glycol collected at the landfill. The option of recycling glycol
utilizing LFG has been included as a part of this study so the Municipality can compare
the recycling costs to its current disposal costs.
Prior to performing a detailed economic analysis of this option, a rough estimate was
calculated using industry-accepted figures. The results of this rough estimate determined
the following:
1. On an annual basis, the Municipality receives $8,400 for the collection and
disposal of 12,000 gallons of glycol ($0.70 per gallon) from its customers.
Section 4 – Economic Analysis
5-12
2. The Municipality’s annual disposal costs for the 12,000 gallons are $35,000.
3. Engineering design, permitting, equipment procurement, construction, startup and
commissioning a fully developed project cost for a glycol distillation system and
heating device will be greater than $300,000.
4. O&M costs of 5% of capital investment will be approximately $15,000 per year
5. 6000 gpy of glycol could be recovered and sold at a price of $2.50 per gallon,
generating an annul income of only $15,000.
6. The payback period for the $300,000 investment exceeds generally accepted
accounting practices.
An initial pro forma was developed for the potential glycol scenario and is contained in
Appendix 18. This pro forma indicated that at a $4.50 per gallon resale price, the
required breakeven quantity is 14,700 gallons per year. Because of processing
constraints, this equates to collecting nearly 30,000 gallons of waste glycol per year.
Again, the MOA currently collects approximately 12,000 gallons per year. Additionally,
MOA is concerned about competing with other private entities for other sources of waste
glycol. Therefore, further evaluation of this beneficial use option appears to be
unnecessary.
6-1
6 SUMMARY OF FINDINGS
A summary of the findings for each of the options presented in Section 5 is provided
below:
• LFG modeling indicates that sufficient recoverable quantities of LFG are present
to support 2.4 MW electricity generation (Option No. 1). The electricity
produced can be sold to several different local utilities, including Municipal Light
& Power.
Negotiation of an electric sales agreement with the a local utility is necessary
under this option. These negotiations are quite often a long and difficult process
and are typically more difficult with the absence of a local or state renewable
energy portfolio standard.
The most lucrative electric sale potential appears to be with MEA (currently
buying power at from Chugach at 5.9 cent per kW) At this rate, a LFGTE project
would breakeven (LFG collection/flaring costs included in pro forma: 5.84 cents
per kW) or be profitable (LFG collection/flaring costs included in pro forma: 4.81
cents per kW). Because MEA is obligated to purchase all their power from
Chugach Electric until 2014, a special exemption will be required. It is anticipated
that renewable energy requirement will soon be requested by the federal
government at local military bases. If this requirement is requested the probability
of obtaining this exemption or a direct sale to another utility or the federal
government is drastically increase.
• The capital and O&M to operate a high Btu LFG plant and inject the LFG into
Enstar’s nearby pipeline (Option No. 2) is not economically feasible.
• The capital and O&M to operate a LFG pipeline to the Municipality of Anchorage
Eagle Valley School (Option No. 3) is not economically feasible.
• The sale of medium Btu LFG to the National Guard (Option No. 4) may be
economically feasible, but there appears to be more lucrative options available
(see Option Nos. 5, 6 and 7).
• Sale of a medium Btu LFG to ML&P, Ft. Richardson (Option No. 5), appears to
economically feasible and provides just slightly better financial results than the
sale of LFG to George M. Sullivan Power Plant No. 2 (Option No. 6) The boiler
identified for conversion are new pieces of equipment and are planned for long
term use on the base. However, Fort Richardson has been included on previous
6-2
base realignment and closure (BRAC) lists and therefore could present
considerable financial risk if closed. In addition, negotiating a gas sales agreement
with the Federal government and the equipment operator (i.e., Honeywell) may be
more troublesome than other options.
• Sale of medium Btu LFG to ML& P’s George M. Sullivan Power Plant No. 2
(Option No. 6) appears to be economically feasible. Only the sale of LFG to the
proposed Fossil Creek Facility (Option No.7) substantially outperforms this
option. Since this plant already exists and is owned by the MOA, this option may
present the least amount of risk.
• Sale of medium Btu LFG to ML& P’s proposed Fossil Creek Facility (Option No.
7) appears to be economically feasible. This option appears to be the most
economically feasible, but does present the risk of delayed construction or even
never being built.
• Option 8, utilizing LFG to treat on-site liquid (leachate and glycol) is not
economically feasible.

The services described in this report were performed consistent with generally accepted
professional consulting principles and practices. No other warranty, expressed or
implied, is made. These services were performed consistent with our agreement with the
Municipality of Anchorage. This report is solely for the use and information of
Anchorage Regional Landfill unless otherwise noted. Any reliance on this report by a
third party is at such party's sole risk.’
Opinions and recommendations contained in this report apply to conditions existing when
services were performed and are intended only for the client, purposes, locations, time
frames, and project parameters indicated. We are not responsible for the impacts of any
changes in environmental standards, practices, or regulations subsequent to performance
of services. We do not warrant the accuracy of information supplied by others, nor the
use of segregated portions of this report.
The LFG generation modeling techniques used by EMCON/OWT and the LFG industry
are, by definition, hypothetical, and can only be used as a very general tool for producing
a range of estimates to aid in determining the direction of further investigations. Actual
LFG generation and collection rates are dependent on many variables, including: refuse
composition, moisture, pH, cover soil permeability, well spacing, continuing fill rates,
etc.. Typically these parameters are not well defined at the time of modeling and/or differ
somewhat from those actually experienced during future site operation.
The LFG generation modeling provided herein was performed with today’s current
standards of practice and no warranty or representation, expressed or implied, is made, as
to the actual LFG production that will occur in the future. Opinions and
recommendations contained in this report are based on the information available and
certain assumptions that were deemed reasonable when our services were performed. We
are not responsible for the impacts of any changes in information, site operations or
methods that may change in the future.

Workorder# 0311168A
One 1 Liter Tedlar Bag sample was received on November 11, 2003. The laboratory performed analysis via
modified EPA Method TO-14A using GC/MS in the full scan mode. The method involves concentrating up
to 0.5 liters of air. The concentrated aliquot is then flash vaporized and swept through a water management
system to remove water vapor. Following dehumidification, the sample passes directly into the GC/MS for
analysis. See the data sheets for the reporting limits for each compound.
Method modifications taken to run these samples include:

Workorder# 0311168B
One 1 Liter Tedlar Bag sample was received on November 11, 2003. The laboratory performed the analysis of
sulfur compounds via ASTM D-5504 using GC/SCD. The method involves direct injection of the air sample into
the GC via a fixed 1.0 mL sampling loop. See the data sheets for the reporting limits for each compound.
The chain of custody information for sample 301B did not match the entry on the sample tag. The discrepancy
was noted in the Login email and the information on the chain of custody was used to process and report the
sample.
Sample 301B was received past the recommended hold time of 24 hours. The discrepancy was noted in the
Login email and the analysis proceeded.
Receiving Notes
Ethyl Methyl Sulfide and n-Butyl Mercaptan coelute with 3-Methyl Thiophene. The corresponding peak is
reported as 3-Methyl Thiophene.

Applied Filter Technology
Workorder# 0311168C
One 1 Liter Tedlar Bag sample was received on November 11, 2003. The laboratory performed analysis via
modified ASTM Method D-1945 for Methane and fixed gases in natural gas using GC/FID or GC/TCD.
The method involves direct injection of up to 1.0 mL of sample. See the data sheets for the reporting limits for
each compound.
Method modifications taken to run these samples include:
Requirement ATL ModificationsASTM D-1945
Sum of total sample
components
Sum of original values
should not differ from
100.0% by more than
1.0%.
Sum of original values may range between 75-125%.
Sample analysis Equilibrate samples to
20-50° F. above source
temperature at field
sampling
No heating of samples is performed.
Sample calculation Response factor is
calculated using peak
height for C5 and
lighter compounds.
Peak areas are used for all target analytes to quantitate
concentrations.
Standard preparation Prepared by blending
pure standards
Purchased blend certified to ± 5% accuracy or better
Normalization Mathematically
normalize results to
equal 100%.
Unnormalized results are reported unless otherwise
specified.
Receiving Notes
The chain of custody information for sample 301B did not match the entry on the sample tag. The
discrepancy was noted in the Login email and the information on the chain of custody was used to process
and report the sample.
The presence of Carbon Monoxide may have been masked by the Methane peak in sample 301B.
Propane and Propylene co-elute. Peak is quantitated as propane.
Analytical Notes
Six qualifiers may have been used on the data analysis sheets and indicate as follows:
J - Estimated value.
E - Exceeds instrument calibration range.
S - Saturated peak.
Q - Exceeds quality control limits.
U - Compound analyzed for but not detected above the detection limit.

LABORATORY NARRATIVE
Siloxanes
Applied Filter Technology
Workorder# 0311168D
Two Vial samples were received on November 11, 2003. The laboratory performed analysis for siloxanes by
GC/MS. A sample volume of 1.0 uL was injected directly onto the GC column. Initial results are in ug/mL. The
units are converted to total micrograms (ug) by multiplying the result (ug/mL) by the total volume (mL) contained
in the impinger. See the data sheets for the reporting limits for each compound.
A Temperature Blank was not included with the shipment. Temperature was measured on a representative
sample and was not within 4 +/- 2 degrees C. Coolant in the form of blue ice was present. The client was
notified via the login fax/email and the analysis proceeded.
Receiving Notes
A front and back impinger was received for each sample. Each impinger was analyzed separately. The results
for each analyte were then additively combined and reported as a single concentration. The reported surrogate
recovery is derived from the front impinger analysis only.
Analytical Notes
Six qualifiers may have been used on the data analysis sheets and indicate as follows:
B - Compound present in laboratory blank greater than reporting limit.
J - Estimated Value.
E - Exceeds instrument calibration range.
S - Saturated peak.
Q - Exceeds quality control limits.
M - Reported value may be biased due to apparent matrix interferences.
File extensions may have been used on the data analysis sheets and indicates
as follows:
a-File was requantified
b-File was quantified by a second column and detector
r1-File was requantified for the purpose of reissue
