  Landfill Gas Projects in Tennessee


Throughout the country, the number of landfill gas energy projects is growing. Recovering methane gas
at solid waste landfills provides significant environmental and economic benefits by eliminating methane
emissions while capturing the gas's energy value. The methane captured from landfills can be transformed
into a cost-effective fuel source for generating electricity and heat, firing boilers, or even powering vehicles.

Permits, incentive programs, and policies for landfill gas energy project development vary greatly from
state to state. To guide landfill gas  energy project developers through the state permitting process and  to
help them to take advantage of state incentive programs, the U.S. Environmental  Protection Agency's
(EPA's) Landfill Methane Outreach  Program (LMOP) has worked with      agencies to develop  individual
primers for states participating in the State Partner Program. By presenting the  latest information on federal
and state regulations and incentives affecting landfill gas energy projects in this primer, LMOP and
Tennessee      officials hope to facilitate development of many of the landfills listed in Table C on      5.

To develop this primer, the     of Tennessee identified all the permits and funding programs that could
apply to landfill gas energy projects developed in Tennessee. It should be noted, however, that the regula-
tions, agencies, and policies described are subject to change. Changes are likely  to occur whenever a
state legislature meets or when the federal government imposes new directions on      and local  govern-
ments. Landfill gas energy project developers should verify and continuously monitor the status of laws and
rules that might affect their plans or the operations of their projects.

This primer is designed to help realize the potential of landfill gas recovery in the state of Tennessee. It
provides information for developers of landfill gas energy projects, as well as all other  participants in such
       •  Landfill owners/operators            • Community officials

       •  Utility companies                   • State regulators

       «  Independent power producers        « Engineers

       «  Utility regulators                    « Equipment vendors

If you are interested in taking advantage of the economic and environmental opportunities in landfill
gas energy recovery in Tennessee, you will need to know the regulatory requirements  that apply.
You will also need to  know what economic incentives are available to help make these projects more
economically viable.
                                    A Primer on Developing Tennessee's Landfill Gas Utilization Potential

To address these needs, this primer covers the following topics:
        *   Federal Regulations and Permits. This section provides information on federal regulations that
           may pertain to landfill  gas energy projects, including solid waste, air quality, and water quality

        •   State Regulations and Permits. This section provides information on state permits that apply to
           landfill gas recovery projects in Tennessee.

        *   Local Regulations and Permits.  Local permit approval will often be needed for landfill gas
           energy projects.

        •   Federal Incentive Programs. This section  presents information on federal incentives that may
           apply to landfill gas energy  projects.

        •   State Incentive Programs. This section presents information about environmental infrastructure
           financing opportunities in the      of Tennessee.

        *   Electricity Restructuring. This section discusses how renewable  energy provisions in
           electricity restructuring regulations might apply to  landfill gas energy projects.

        •   Voluntary Reporting of Greenhouse Gases. This section discusses a program allowing
           organizations to gain recognition for environmental achievements related to greenhouse
           gas emissions.

In order to promote the use of landfill gas as an energy source, EPA has established the Landfill Methane
Outreach Program (LMOP). The goals  of LMOP are to reduce methane emissions from landfills by:
        •   Encouraging environmentally and economically beneficial landfill gas energy development

        •   Removing barriers to developing landfill gas energy projects

To achieve these goals, EPA establishes alliances with four key constituencies:
        •   State environmental and energy agencies

        •   Energy users/providers (including investor-owned, municipal, and other public  power utilities;
           cooperatives; direct end users; and power marketers)

        •   Industry (including developers, engineers, and equipment vendors)

        •   Community partners (municipal  and small private  landfill owners and operators; cities, counties,
           and other local governments; and community groups)

EPA establishes these alliances through a Memorandum of Understanding (MOD). By signing the MOU,
each Partner acknowledges a shared commitment to  promoting landfill gas  energy recovery at solid waste
landfills, recognizes that the widespread use of landfill gas  as an energy resource will reduce methane and
other air emissions, and commits  to certain activities that enhance the development of this resource.

As of May 2003, more than 340 landfill methane recovery projects were operating in the United States.
EPA estimates that up to 500 landfills across the United States could install  economically viable landfill gas
energy projects.
       Landfill Gas Projects in Tennessee


The Tennessee State LMOP task force has been formed to review state regulations and policies to explore
opportunities for overcoming barriers to landfill gas energy projects. The overall purpose of the state task
force is to encourage information sharing and increased coordination among interested parties on landfill
gas energy project development in Tennessee.

The Tennessee State LMOP task force is comprised of the following members:

 Part 1:  Regulations and Permits
The following section discusses federal regulations that may pertain to landfill gas energy projects,
Landfill gas energy projects can be subject to solid waste, air quality, and water quality regulations. The
federal regulations are presented in general terms because individual state/local governments generally
develop their own regulations for carrying out the federal mandates. Specific requirements may therefore
differ among states. Project developers should contact relevant federal agencies and, in some cases,
state agencies for more detailed information and applications. The discussion of each key federal
regulation/permit contains three components:
        •  Importance of the regulation/permit to landfill gas energy  project developers

        •  Applicability to landfill  gas energy projects

        •  Description of each regulation/permit

1.1            Air Act

The Clean Air Act regulates emissions of pollutants to ensure that air quality meets specified health and
welfare standards. The CAA contains three provisions that may affect landfill gas energy projects: (1) New
Source Performance Standards (NSPS) and Emission Guidelines; (2) National  Emission Standards for
Hazardous Air Pollutants (NESHAP); and (3) New Source Review (NSR). Project developers who are  plan-
ning to construct a new landfill  gas energy system or who plan to modify a landfill operation to incorporate
a landfill gas energy system must obtain a Permit to Construct (PTC) permit from the responsible regulato-
ry agency if emissions from the project       the major facility emission thresholds. The PTC permit
specifies the NSPS and NSR requirements that the project must meet (Chapter 1200-3-9). Landfill energy
plants that are part of major sources must also obtain Title V Operating Permits that consolidate the vari-
ous air regulatory and reporting requirements into a single operating  permit. The general requirements of
NSPS, NESHAP, NSR, and Title V for landfill gas energy projects are discussed below.


Importance    Landfill gas energy projects can be part of a compliance strategy to meet EPA's new
               emissions  standards for landfill  gas.

Applicability   Landfills meeting certain design capacity, age, and emissions criteria are required to col-
               lect landfill gas and to either flare it or use  it for energy.

Description    EPA final regulations under the  CAA amendments require large landfills to collect and con-
               trol landfill  gas. Specifically, landfills that are designed to be at least 2.5 million
               megagrams (Mg) and 2.5 million cubic meters in size and have estimated emissions of
               non-methane organic compounds (NMOC) of at least 50 Mg/year must reduce their emis-
               sions of landfill gas. The regulations identify NMOC as a surrogate for landfill gas.
               Therefore,  the emission reductions required in the rules are specified as reductions of
       Landfill Gas Projects in Tennessee

               NMOC. Landfills can use flares or energy recovery projects to meet the emission reduc-
               tion requirements,

               Landfill gas emissions were targeted in these rules because of the potential negative
               impact on human health and the environment from the volatile organic compounds
               contained in the gas.  In addition, the contribution of landfill gas to local smog formation,
               local odors, and the potential for explosions or landfill fires were included in the
               decision-making process.

               For landfills that commenced construction before May 30, 1991, and received waste after
               November 8, 1987  ("existing landfills"), the Emission Guidelines  (40 CFR Part 60 Subpart
               Cc) apply. For landfills that commenced construction, reconstruction, or modification on or
               after May 30, 1991  ("new landfills"), the       (40 CFR Part 60  Subpart WWW) apply.
               The collection and control requirements of each of these standards are the same; only the
               start of the compliance clock differs.

               The final regulations were published in the Federal Register on March 12, 1996, but clari-
               fying amendments have been made since. The regulations (as revised) can be found  in
               the Code of Federal Regulations at 40 CFR Part 60, Subparts Cc and WWW. Additional
               amendments were  proposed on May 23, 2002 (67 FR 36476), but were not final as of
               December 2002.

               Landfill gas collection systems and either gas treatment or control  achieving 98 percent
               NMOC destruction  or 20 ppmv outlet NMOC concentration are required for existing and
               new landfills that meet both of the following criteria:
                 (1) Capacity - maximum design capacity greater than or equal to 2.5 million Mg (about
                     2.75 million tons) and 2.5 million cubic meters.

                 (2) Emissions - annual NMOC emission rate is greater than 50 Mg (about 55 tons).
                     Landfills below the capacity and emissions thresholds have reporting requirements
                     to demonstrate their capacity and/or emission levels,  but are not required to apply


Importance    Landfill gas energy projects can be part of a compliance strategy to meet EPA's new
               emissions standards for landfill gas.

Applicability   Landfills meeting certain design capacity,  age, and emissions criteria are  required to
               collect landfill gas and to either flare it or use it for energy.

Description    The final municipal  solid waste landfills NESHAP was published in the Federal Register
               on January 16, 2003 (68 FR 2227). It affects the same landfills and has the same control
               requirements as the NSPS and Emission  Guidelines. As with the NSPS, the emission
               reduction requirements of the rule are  specified as NMOC. Landfills with design  capacities
               of at least 2.5 million Mg and 2.5 million cubic meters and that have estimated annual
               NMOC emission rates of at least 50 Mg/year are required to collect and treat or control
               landfill gas emissions. These control requirements are the same as the NSPS and
               Emission Guidelines with one exception: large landfills (i.e., those that exceed the
               2.5 million Mg and cubic meters threshold) that operate part or all of the landfill as a
               bioreactor must install collection and control systems for the bioreactor earlier than would
               be required by the NSPS, even if total estimated emissions do not yet exceed 50 Mg/year.
                                    A Primer on Developing Tennessee's Landfill Gas Utilization Potential

               The control systems may also be removed earlier from bioreactors, Bioreactors generate
               landfill gas more quickly than conventional landfills, but also generate the gas for a shorter
               period of time.

               The NESHAP also contains additional record keeping and reporting requirements com-
               pared to the NSPS. Landfills that are required to collect and control landfill gas must
               develop a start-up, shutdown,  and malfunction (SSM) plan and report SSM events. The
               NESHAP also requires semiannual compliance reporting, instead of the annual reporting
               required by the  NSPS. The NESHAP defines types of deviations from the standards that
               must be reported in the semiannual reports, for example, periods when monitored control
               device operating parameters are outside of specified ranges.

Importance    New landfill gas projects may be required to obtain construction permits under New
               Source Review (NSR). Depending on the     in which the project is located, obtaining
               these permits may be the most critical aspect of project approval.

Applicability   The combustion of landfill gas results in emissions of carbon monoxide, oxides of nitro-
               gen, and PM-10. Requirements vary for control of these emissions depending on local air
               quality. The relevant standards for a particular area will be discussed in Section 2 of Part
               1, Overview of State Regulations and Permits. Applicability of these standards to landfill
               gas projects will depend on the level of emissions resulting from the technology used in
               the project and  the project's location (i.e., attainment or nonattainment area).

Description    CAA regulations require  new stationary sources and modifications to existing sources of
               certain air emissions to undergo NSR before they begin construction. The purpose of
               these regulations is to ensure  that sources meet the applicable air quality standards for
               the area in which they are located. Because these regulations are complex,  a landfill
               owner or operator may want to consult  an attorney or expert familiar with NSR for more
               information about permit requirements.

               The existing CAA regulations for attainment and maintenance of ambient air quality
               standards regulate six criteria  pollutants: ozone,  nitrogen dioxide (NO2), carbon monoxide
               (CO), particulate matter (PM-10), sulfur dioxide (SO2), and lead. The CAA authorizes the
               EPA to set both health and public welfare-based national ambient air quality standards
               (NAAQS) for each criteria pollutant. Areas that meet the NAAQS for a particular air
               pollutant are classified as being in "attainment" for that pollutant and those that do not are
               in "nonattainment." Because each     is required to develop an air quality implementa-
               tion plan (called a       Implementation Plan or SIP) to attain and maintain compliance
               with the NAAQS in each Air Quality Control Region within the state, specific permit
               requirements will vary by state. (See 40 CFR 51.160-51.166 for more information.)

               The location and     of the landfill gas energy project will dictate what kind  of construc-
               tion and operating permits are required. If the landfill is located in an     that is in
               attainment for a particular pollutant, the landfill gas energy project may have to undergo
               Prevention of Significant Deterioration permitting. Nonattainment Area permitting is
               required for those landfills that are located in       that do  not meet the NAAQS for a
               particular air pollutant. Furthermore, the level of emissions from the project determines
               whether the  project must undergo major NSR or minor NSR. The requirements of major
       Landfill Gas Projects in Tennessee

               NSR permitting are greater than those for minor NSR. The following provides more detail
               on new source permits:


Prevention of Significant Deterioration (PSD) review is used in attainment areas to determine whether a
new or modified emissions source will cause significant deterioration of local air quality. Tennessee
Department of Air Pollution Control (APC) can assist landfill gas energy project developers in determining
whether a proposed project requires PSD approval. Applicants must determine PSD applicability for each
individual pollutant.

For each pollutant for which the new or modified source is considered major (i.e., exceeds specified
emission thresholds), the PSD major NSR permitting process requires that the applicants determine the
maximum degree of reduction achievable through the application of available control technologies.
Specifically, major sources may have to undergo any or all of the following four PSD steps:
        *  Best Available Control Technology (BACT) analysis

        *  Monitoring of local air quality

        *  Source impact analysis/modeling

        *  Additional impact  analysis/modeling (i.e., impact on vegetation, visibility, and Class I areas)

(See 40 CFR Part 52.21 for more information on PSD.)

Minor sources and minor modifications are exempt from this process, but these sources must still obtain
construction  and operating air permits. See Chapter 1200-3-9 for more information.

A source located in an area that has been designated nonattainment for one or more of the six criteria pol-
lutants may be subject to the  nonattainment for such pollutant. Ozone is the most pervasive nonattainment
pollutant and the one most likely to affect landfill gas energy projects. Because NOx and VOC emissions
contribute to ozone formation, the emission thresholds that trigger major NSR and the control requirements
are more stringent in ozone nonattainment      than in attainment areas. Therefore,  NOx permitting has
been an issue for some landfill energy projects.

A proposed new emissions source or modification of an existing source located in a nonattainment
must undergo nonattainment  major NSR if the new source or the modification is classified as major (i.e., if
the new or modified source exceeds specified emissions thresholds). To obtain a nonattainment NSR per-
mit for criteria pollutants, a project must meet two requirements:
        •  It must use technology that achieves the Lowest Achievable Emissions Rate (LAER) for the
          nonattainment pollutant.

        *  It must arrange for an emissions reduction at an existing combustion source that offsets the
          emissions from the new project at specific ratios.

Potential Exemptions

EPA furnished a guidance document to      and regional  permitting authorities that provides an exemption
from major NSR permitting requirements for landfill projects that qualify as "pollution control projects." An
existing landfill that plans to install a landfill gas energy recovery project may qualify as a pollution control
project as long as it reduces non-methane organic compounds (NMOC) at the site. Under the guidance,
                                    A Primer on Developing Tennessee's Landfill Gas Utilization Potential

the permitting authority may exempt the project from major NSR, provided it meets all other requirements
under the CAA and the state, including minor source requirements. In nonattainment areas, offsets will still
be required, but need not exceed a 1:1 ratio. States have discretion to exercise the increased flexibility
allowed by the guidance on a case-by-case basis.


Importance    Many landfill gas energy projects must obtain operating permits that satisfy Title V of the
               1990 CAA Amendments.

Applicability   Any landfill or landfill gas energy plant that is a major source,  as defined by the Title V
               regulation (40 CFR Part 70), must obtain an operating permit.

Description    Title V of the CAA requires that all major sources obtain new federally enforceable operat-
               ing permits. The purpose of the permit is to consolidate all air emission limits, monitoring,
               record keeping, and reporting requirements that apply to the source in a single permit.
               Each major source must submit an application for an operating permit that meets guide-
               lines spelled out in individual      Title V programs. The operating permit describes the
               emission limits and operating  conditions that a facility must satisfy and specifies the
               reporting requirements that a  facility must meet to show compliance with the applicable air
               pollution regulations (e.g., NSPS, NESHAP, NSR). A Title V operating permit must be
               renewed every five years.

1.2                                                                               D

Importance    Before a landfill gas energy project can be developed, all Resource Conservation and
               Recovery Act (RCRA) Subtitle D requirements (i.e., requirements for non-hazardous
               waste management)  must be  satisfied.

Applicability   Methane is explosive in certain concentrations and poses a hazard if it migrates beyond
               the landfill facility boundary. Landfill gas collection systems must meet RCRA Subtitle D
               standards for gas control.

Description    Since October 1979,  federal regulations promulgated under Subtitle D of RCRA have
               required controls on the migration of landfill gas.  In 1991, EPA promulgated landfill design
               and performance standards. The newer standards apply to municipal solid waste landfills
               that were active  on or after October 9, 1993. Specifically, the standards  require monitoring
               of landfill gas and establish performance standards for combustible gas migration control.
               Monitoring requirements must be met at landfills  not only during their operation, but also
               for a period of 30 years after closure.

               Landfills affected by RCRA Subtitle D are required to control gas by establishing  a pro-
               gram to periodically check for methane emissions and prevent offsite migration. Landfill
               owners and operators must ensure that the concentration of methane gas does not
                     Twenty-five percent of the lower explosive  limit for methane  in facilities' structures

                     The lower explosive limit for methane at the facility boundary

               Permitted limits on methane levels reflect the fact that methane is  explosive within the
               range of 5 to  15  percent concentration in air. If methane emissions exceed permitted
               limits, corrective action (i.e., installation of a landfill gas collection system) must be taken.
Landfill Gas Projects in Tennessee

               Subtitle D may provide an impetus for some landfills to install energy recovery projects in
                     where a gas collection system is required for compliance. (See 40 CFR Part 258
               for more information.)
Importance    Landfill gas energy projects may need to obtain NPDES permits for discharging waste-
               water that is generated during the energy recovery process.

Applicability   Landfill gas condensate forms when water and other vapors condense due to temperature
               and pressure changes within the collection system. This wastewater must be removed
               from the collection system. In addition, landfill gas energy projects may generate waste-
               water from system maintenance and cooling tower blow down.

Description    NPDES permits regulate discharges of pollutants to surface waters. The authority to issue
               these permits is delegated to      governments by EPA. The permits, which typically last
               five years, limit the quantity and concentration of pollutants that may be discharged. To
               ensure compliance with the limits, permits require  wastewater treatment or impose other
               operation conditions. The state water offices or EPA regional office can provide further
               information on these permits.

               The permits are required for three categories of sources and can be issued as individual
               or general permits. A landfill gas energy project would be included in the "wastewater
               discharges to surface water from industrial facilities" category and would require an
               individual permit. An individual permit application for wastewater discharges typically
               requires information on:
                     Water supply volumes

                     Storm water treatment

                     Water utilization

                     Plant operation

                     Wastewater flow

                     Materials and chemicals used

                     Characteristics and disposal methods


                     Planned improvements

Importance     Landfill gas energy projects may need Clean Water Act (CWA) Section 401  certification for
                constructing pipelines that cross streams or wetlands.

Applicability    Landfill gas recovery collection pipes or distribution pipes from the landfill to a nearby
                gas user may cross streams or wetlands. When construction or operation of such pipes
                causes any discharge of dredge into streams or wetlands, the project may require
                Section 401 certification.

Description     If the construction or operation of facilities results in any discharge into streams or wet-
                lands, such construction is regulated under Section 401. This requirement may affect the
                construction of landfill gas energy project facilities or pipelines to transport landfill gas.

                The applicant must obtain a water quality certification from the state in which the dis-
                charge will originate. The certification should then be sent to the U.S. Army  Corps of
                Engineers. The certification indicates that such discharge will comply with the applicable
                provisions of Sections 301, 302, 303, 306,  and 307 of the  CWA.


The  following are brief descriptions of how other federal permits could apply to landfill gas energy
project development:
        •   IRCRA Subtitle C could apply to a landfill gas  energy project if it produces hazardous waste.
           While some landfill gas energy projects can return condensate to the landfill, many dispose
           of it through the public sewage system after some form of onsite treatment. In a few cases, the
           condensate may contain high enough concentrations of heavy metals and organic chemicals
           for it to be  classified as a hazardous waste, thus triggering federal Subtitle C regulation.

        *   The Historic Preservation Act of 1966 or the Endangered Species Act could apply if power lines
           or gas pipelines associated with a project infringe upon a historic site or an area that provides
           habitat for  endangered species.

        •   Requirements of the Uniform Relocation Assistance and Real Property Acquisitions Act of 1970,
           as  amended (Uniform Act), will apply to landfill gas energy projects, if federal funds are used for
           any part of project design, right of way acquisition, or construction. The Federal Highway
           Administration is the lead agency for issues concerning the Uniform Act.

Application Review  When construction permit or Title V permit applications are submitted, TDAPC
Process             reviews them for completeness. TDAPC makes a completeness determination
                     within 60 days of the receipt of a Title V permit application and within 30 days  of the
                     receipt of a construction permit application. The applicant is notified in writing of
                     adequacy or any deficiencies.

                     Air Quality Construction Permit
                     • Upon receipt of a construction permit application, a public notice is published in a
                       newspaper  of local circulation in the proximity of the applicant. A construction
                       permit for a minor source  must be issued within 115 days after receipt of a
                       complete application.
                     • Major source (PSD) draft construction permits go through a public review process
                       where the public, affected states, and EPA's comments are solicited. A public
                       hearing is held if significant interest is displayed. After considering public
                       comments and a final supervisory review, a final decision is made, and the permit
                       is issued or denied. For PSD major sources, the permit is to be issued within six
                       months after receipt  of a complete application.
                     « Construction permits are issued for the  period of time required to complete
                       construction and to meet any startup conditions identified in the permit, which is
                       approximately one year.

                      limitation on its permit that would render it a conditional major or synthetic minor
                      source. Minor source fees are based on  the sum of the allowable and/or actual
                      emissions of all regulated pollutants at the  source. An annual emission fee is
                      not charged for carbon monoxide. All annual emission fees are due by the first
                      day of the month in which the fee is due (based upon  the county in which the

                     A new facility cannot begin construction without submitting Parts I and II and
                     receiving an effective permit.

Application          Permit applications are evaluated by inspecting the facility and checking its
Process             consistency with Parts I  and II to determine whether performance and design
                     standards have been met.
Review Process
After the Part I application is received and reviewed for completeness, a preliminary
public notice is issued. The state archeologist reviews the site for the existence of
burial grounds. The Part II items then are submitted to the Division and are
reviewed by a committee. When all documents and approvals have been met, a
second  public notice of intent to issue a permit is issued. Public response to this
second  notice may generate another public notice to hold a public hearing.  If
requested, the Division may give notice of a public hearing concurrently with the
second  public notice of intent to issue a permit. After review of the public comments,
a final public notice with the permit decision is issued.

The application normally is processed in at least 270 days. The entire permit
process may take from 16 to 32 months, depending on the type of facility, public
interest, public hearings, revisions, appeals, and site preparation. Landfill permits
are valid for the life of the facility, as permitted, as long as it complies with
regulations and annual maintenance fees are paid.

The mission of the TRA is to promote the public interest by balancing the interests of utility consumers and
providers while facilitating the transition to a more competitive environment.

Established in 1996, TRA was created to  meet the challenge of the changing telecommunications and
utility environment. TRA is charged with the responsibility of setting the      and service standards of
privately owned telephone, natural gas, electric, and water utilities.

Depending on the use of the final product, it may be necessary for the project developer to obtain
a Certificate of Convenience and Necessity (CCN) from the TRA. Certain other gas pipeline safety
regulations may also apply. Therefore, it is recommended that the project developer contact the TRA
before a methane gas operation is instituted to determine if a CCN  is necessary. If necessary, a CCN
application is made by filing a Petition with the TRA and paying a $25 fee.

The TRA will make a review of the CCN  Petition and may require additional information from the project
developer as well as a public hearing. A formal decision on the CCN application will  be reached in a public
meeting of the TRA Directors.

There is no set rule,  regulation,  or statute concerning the length of the review period for an energy-related
CCN. However, the TRA strives to process such applications in an expeditious manner.


Annual inspection and supervision fees are required from all  utilities under the jurisdiction  of the TRA. The
minimum fee is $100.

Within the framework of federal and state regulation, local governments may have some jurisdiction over
landfill gas energy development in certain cases. Typically, local permits address issues that affect the
surrounding  community. These permits generally fall under the categories of construction, environment
and health, land use, and water quality/use. It should be noted, however, that some local standards and
regulations are stricter than state or federal regulations.

          to                                 of

The following six steps  will assist landfill gas energy project developers to achieve successful local permits

   Step 1.    Determine which local authorities have jurisdiction over the project on the project site(s).

   Step 2.    Contact the  local, city, and/or county planning and public works departments to obtain
              information about applicable permits and to discuss your plans. Meeting with agency staff
              to  discuss the landfill gas energy project and required permits often helps to expedite the
              permitting process.

   Step 3.    Obtain essential information regarding each  permit,  including:
                      •  What information is required

                      •  The permitting process that should be followed

                      •  Timeframes (including submittal, hearing, and decision dates)

   Step 4.    Obtain copies of the regulations to compare and verify what is required in the permit
              applications. If they differ, contact the appropriate permitting agency.

   Step 5.    Submit a complete application. Incomplete applications typically result in processing delays.

   Step 6.    Attend meetings or hearing(s) where the application will be discussed to respond to any
              questions that are raised. Failure to do so could result in delays.

 Part 2:  Incentive  Programs
There are three federal incentive programs that may apply to landfill gas energy projects: the Renewable
Energy Production Incentive (REPI), Qualifying Facilities (QF) certification, and Section 29 Tax Credit. Each
program is described below.


The Renewable Energy Production Incentive (REPI), mandated under the Energy Policy Act of 1992, may
provide a cash subsidy of up to  1.5 cents per kilowatt-hour to owners  and operators of qualified renewable
energy sources, such as landfills, that began operation between October 1993 and  September 2003.
Public sector entities may qualify to earn a cash subsidy based on a tier system. Tier 1 facilities (solar,
wind, geothermal, or closed-loop biomass) receive full payments or pro-rata payments if funds are too
minimal to match  all requests. Any remaining funds fall to Tier 2, which includes landfill gas facilities.
If there are insufficient funds to cover Tier 2 applicants, a pro-rata system is implemented. The U.S.
Department of Energy (DOE) will make incentive payments for 10 fiscal years, beginning with the fiscal
year in which application for payment for electricity generated by the facility is first made and the facility
is determined by DOE to  be eligible for receipt of an incentive payment. The period for payment under
this program ends in fiscal year  2013. REPI payments are subject to adjustment because Congress
appropriates REPI payments each year.

Landfill gas energy projects that generate electricity will benefit from the Qualifying Facilities (QF)
certification, which is granted through the Federal Energy Regulatory Commission (FERC). The following
information describes the benefits of QF status and the steps for applying for such status.

The Public Utility Regulatory Policies Act (PURPA), one of five parts of the National Energy Act of 1978,
was designed to promote conservation of energy and energy security by removing barriers to the develop-
ment of cogeneration facilities and facilities that employ waste or renewable fuels. Such facilities are called
Qualifying Facilities or QFs. Under PURPA, utilities are required to purchase electricity from QFs at each
utility's avoided cost of generating power. PURPA provides that a small power production facility, such as a
landfill gas energy project that       FERC standards, can become a QF.

In order to apply for QF status, applicants must prepare either: (1) a Notice of Self-Certification, which
asserts compliance with the FERC's technical and ownership criteria;  or (2) an Application for Commission
Certification of Qualifying Status, which requires a  draft Federal Register notice and provides actual FERC
approval of QF status. In either case, the applicant must also file Form 565, which is a list of questions
                                   A Primer on Developing Tennessee's Landfill Gas Utilization Potential

about the project, and must pay any filing fees associated with certifications, exemptions, and other activi-
ties. FERC will provide the QF "Info Packet," which describes the necessary steps, requirements, and
background information. After submittal of the initial application, further justifications and submittal of infor-
mation may be required.

1.3               29

Developers of landfill gas energy projects who sell landfill gas to an unrelated third party may qualify for a
tax credit under Section 29 of the  Internal Revenue Service (IRS) tax code. In order to take advantage of
the credits, project developers may bring in an outside party when developing power projects. The Section
29 tax credit was established in 1979 to encourage development of unconventional gas resources, such
as landfill gas. Section 29  tax credits are available through 2007 to landfill gas projects that had binding
contracts in place by December 31, 1996 and were placed in service by June 30, 1998. The credit has
been extended several times by the U.S. Congress. Currently, it is discontinued.

Tennessee Valley Authority (TVA) and local public power companies, working with input from the
environmental community, have created a program called Green Power Switch® to  produce electricity
from cleaner, greener sources and incorporate the electricity into the Tennessee Valley's power mix. The
program was started for two main reasons:

       1.  TVA's mission to improve quality of life while minimizing the negative environmental impact
          of business.

       2.  The customer wanted an environmental energy alternative.

Green Power Switch® began on Earth Day 2000 and is expanding to consumers throughout the Tennessee
Valley as more resources for generating renewable power become available.

In the start-up       of Green Power Switch®, methane gas from landfills will provide the largest source
of cleaner energy. At present, TVA has two sources of methane gas:  the Middle Point Landfill near
Murfreesboro, Tennessee, and the City of Memphis Wastewater Treatment Plant, which produces a
methane by-product that is co-fired at TVA's Allen Fossil Plant.

The Renewable Portfolio Standard (RPS) is a plan to generate more clean power from sustainable and
secure energy sources. The      of Tennessee does not presently have a state-implemented Renewable
Portfolio Standard (RPS). The      has closely followed a national RPS that will require utility companies
to use alternative energy sources to  generate electricity by setting a goal of at least 20 percent of the
overall power mix to come from clean and sustainable sources by 2020.

Electricity restructuring refers to the introduction of competition into both the wholesale and retail electricity
markets. Until now, electric utilities operated as monopolies authorized by federal and      regulatory
authorities as the sole provider of electric service to consumers within a specific service territory. Under
restructuring, utilities will lose these monopolies, enabling other energy providers to compete for their
customers. With retail  choice, independent power producers are allowed to sell energy directly to retail
customers utilizing  both the transmission grid in the region and the distribution system of the local electric
utility. The desired result is more energy options for consumers, lower energy prices, and greater use of
renewable energy sources.

Efforts to restructure the electric utility industry began in 1978 with passage of the Public Utilities
Regulatory Policies Act (PURPA), which required utilities to buy a portion of their power from
unregulated power generators in an effort to encourage the development of smaller generating
facilities, new technologies, and renewable energy sources. The National Energy Policy Act of 1992
(EPACT) expanded on PURPA, allowing  more types of unregulated companies to generate and  sell
electricity, effectively creating a competitive wholesale market for electric power.

Restructuring at the retail level has been a hot issue in many states since the passage of EPACT, which
delegated to states the authority to introduce competition among electric utilities within  their borders. As of
January 2002, 18       and the District of Columbia have either enacted enabling legislation or issued a
regulatory order to implement retail access. Retail        in these jurisdictions is either currently available
to all or some customers or will soon be available. Six states have either passed legislation or issued
regulatory orders to delay implementing retail access. Twenty-six states, including Tennessee, have not
enacted enabling legislation to restructure the electric power industry or implement retail access. After
being first to enact  retail choice, California has suspended direct retail access.

The Voluntary Reporting of Greenhouse Gases Program, created by Congress under Section 1605(b) of
the Energy Policy Act of 1992, provides an opportunity for any company, organization, or individual to
establish a public record of their greenhouse gas emissions, reductions, or sequestration achievements in
a national database. The data submitted to the program is made publicly available via CD-ROM and the
Internet, Those who report to 1605(b) can gain recognition for environmental stewardship, demonstrate
support for voluntary approach toward achieving environmental policy goals, support information exchange,
and inform the public debate about greenhouse gas emissions.
