This glossary is compilation of terms and definitions used throughout this guidance document.

Access management - Policies, design criteria, and facilities that minimize the number of
driveways and intersecting roads accessing a main thoroughfare; includes parallel service roads,
shared driveways, median barriers, and curb cut limitations.

Active solar technology -Used to convert solar energy into usable light, heat, cause air-
movement for ventilation or cooling, or store heat for future use. Active solar uses electrical or
mechanical equipment, such as pumps and fans, to increase the usable heat in a system.

Air barriers - Systems of materials used to control airflow in building enclosures.

Biodiesel - A domestically produced, clean-burning, renewable substitute for petroleum diesel.
Biodiesel is  a liquid fuel made up  of fatty acid alkyl esters, fatty acid methyl esters (FAME), or

different from fossil fuels, which are derived from long dead biological material. Various plants
and plant-derived materials are also used for biofuel manufacturing.

Biomass - A renewable energy source that refers to living and recently dead biological material
that can be used as fuel or for industrial production. In  this context, biomass refers to plant
matter grown or used to generate electricity or produce (for example: trash such as dead trees and
branches, yard clippings and wood chips), and it also includes plant or animal matter used for
production of fibers,  chemicals or heat. Biomass may also include biodegradable wastes that can
be burnt as fuel.

fuels, power, and value-added chemicals from biomass.

Brownfields - Real property, the expansion, redevelopment, or reuse of which may be
complicated by the presence or potential presence of a  hazardous substance, pollutant, or
contaminant.

Building commissioning - A project management practice that formalizes review of all project
expectations for facilities and their systems during planning, design, construction, and occupancy
phases.  It is an umbrella process that seeks to improve energy efficiency and indoor air quality
by uncovering deficiencies in design or installation using peer review, inspection and functional
performance testing,  and by delivering preventive maintenance plans, tailored operating
manuals, and training procedures.

Building envelope - Consists of all exterior components of a building.

1.1 Purpose and Intent of This Reference

Energy efficiency—obtaining identical services or
output with less energy input—offers one of the lowest
cost means of reducing U.S. energy bills, preventing
pollution and addressing climate change. As one of the
largest energy consumers in the United States, the
federal government has taken on the responsibility to lead by example by promoting energy
efficiency. By more fully integrating energy efficiency considerations throughout the actions,
decisions and operations of the federal government, the U.S. could not only make substantial

This reference document provides background information on federal energy efficiency
legislation, policies, guidance and programs, as well as current energy efficiency technologies,
standards, and products. These programs and documents have very specific requirements. For
this reason, federal agencies are well aware of energy efficiency requirements for their actions
and activities. 309 Reviewers should identify whether they are addressed in EISs. It is
understood that rather than repeating a lengthy discussion on these requirements, the EISs will
most likely incorporate them by reference by citing the appropriate document.  Many times these
documents are made available via a link to a web site in the EIS. In most cases, this should
suffice.

This reference is intended for reviewers within the U.S. Environmental Protection Agency (EPA)
who review and comment on National Environmental Policy Act (NEPA) documents, in
accordance with EPA's responsibilities for environmental review under §309 of the Clean Air
Act (CAA).

The goal of the reference is to provide information to assist EPA reviewers  to:

1.   Prepare scoping comments on environmental impact statements (EISs) that address energy
     efficiency;
2.   Consider energy efficiency issues most appropriate to a specific type of federal action
     presented in an EIS;
3.   Support the development of EPA's comments under CAA §309.

                                                       Process
The National Environmental Policy Act (NEPA) was
signed into law on January 1, 1970. NEPA, as
amended (42 U.S.C. 4321 et seq.), requires all federal
agencies to, among other things, assess the
environmental impacts of major federal actions
significantly affecting the quality of the human
environment (e.g., issuing permits, spending federal
money, or taking actions on federal lands). When an
agency concludes that a proposed major federal
action has the potential for causing significant           ^                              '
environmental impacts, it is required to prepare a detailed statement, known as an environmental
impact statement (EIS). The purpose of the EIS is to inform the federal decision makers and the
public of the environmental impacts of the project and reasonable alternatives which would
avoid or minimize adverse impacts or enhance the quality of the human environment.  In part,
NEPA states that all federal agencies shall "utilize a systematic, interdisciplinary approach which
will insure the integrated use of the natural and social sciences and the environmental design arts
in planning and in decision-making which may have an impact on man's environment" (42
U.S.C. 4332).

2.2 CEQ Regulations Implementing NEPA, 40 CFR Part 1500

The President's Council on Environmental Quality's (CEQ's) NEPA-implementing regulations,
at 40 CFR Parts 1500 - 1508, establish minimum general procedures that assure NEPA
compliance. These CEQ regulations establish a multistage process that describes how an agency
is to analyze and describe any significant environmental impacts that could result from carrying
out a proposed major federal action.

NEPA and the CEQ regulations require that, when a federal agency proposes legislation or
another major federal action significantly affecting the quality of the human environment, the
agency must prepare a  detailed statement of the environmental effects  and obtain comments from
any other federal agency having jurisdiction by law or special expertise with respect to any
environmental impact involved (42 USC 4332(C); 40 CFR 1503.1). In accordance with the CEQ
regulations, each federal agency has developed its own NEPA rules and/or agency procedures.

2.3 CEQ Guidance Regarding NEPA Regulations

Since NEPA was enacted, CEQ has issued many guidance documents to assist federal agencies
in complying with the CEQ regulations for implementing the Act, preparing high-quality NEPA
documents, and improving the NEPA process.
                                       2-1                  EPA Publication No. 315-R-09-001

                                            Energy Efficiency Reference for Environmental Reviewers
One of the most widely referenced CEQ guidance documents is the 1981 memorandum to
federal agencies, Forty Most Asked Questions Concerning CEQ's National Environmental Policy
Act Regulations (CEQ 1981). This guidance provided clarification on topics including the range
of alternatives, implementing actions that are the subject of an ongoing NEPA review, public
involvement, cooperating agencies, and contents of specific EIS sections, among others.

Other CEQ guidance includes the following documents that are widely applicable or that may be
particularly relevant to reviewing EISs for energy efficiency projects:

•  A Citizen's Guide to the NEPA: Having Your Voice Heard (CEQ 2007a)
•  Reporting NEPA Status and Progress for Recovery Act Activities and Projects, April 3, 2009
    (CEQ 2009)
•  Aligning National Environmental Policy Act Processes with Environmental Management
   Systems: A Guide for NEPA and EMS Practitioners, April 2007 (CEQ 2007b)
•   Guidance on the Consideration of Past Actions in Cumulative Effects Analysis, June 24, 2005
    (CEQ 2005)
•  EnvironmentalJustice: Guidance Under the National Environmental Policy Act, December
    10, 1997 (CEQ 1997a)
•   Considering Cumulative Effects Under the National Environmental Policy Act, January 1997
    (CEQ 1997c)
•  Pollution Prevention and the  National Environmental Policy Act, January 12,  1993 (CEQ
    1993)
•   Guidance Regarding NEPA Regulations, 1983 (CEQ 1983).

2.4 Section 309 of the Clean Air Act

Section 309 of the Clean Air Act, as amended in 1970 (42 U.S.C. 7609),  directs EPA to review
and comment in writing on the environmental impacts of, among other things, "newly authorized
federal projects for construction and any major federal action (other than a project for
construction) of a federal agency to which 42 USC 4332(C). . . applies"  and to make those
reviews available to the public. If EPA determines that any such action is environmentally
unsatisfactory, the action will be  referred to CEQ.

Section 309 confers upon EPA review responsibilities for proposed major federal  actions. The
EPA Administrator has delegated to the Office of Federal Activities (OFA) the authority to
review and comment on EISs that are multi-regional in scope and regulations proposed by other
federal agencies for which there are national policy implications. The Administrator has
delegated to the ten EPA Regional Administrators the authority to review and comment on
region-specific EISs. EPA has developed a set of criteria for rating draft EISs. The rating system
provides a consistent method for  evaluating Draft EISs (EPA 2002). In the event EPA
determines that:
    1)  the agency's action involves adverse environmental impacts that are  of sufficient
       magnitude that EPA believes the proposed action should not proceed as proposed;
   2)  the draft EIS has been rated environmentally unsatisfactory;
    3)  the final EIS continues to be environmentally unsatisfactory;
   4)  and every effort has been  made to resolve the environmental issues at the agency level;
                                        2-2                  EPA Publication No. 315-R-09-001

-------
                                                                               March 2010
                                            Energy Efficiency Reference for Environmental Reviewers
EPA will determine whether the action is unsatisfactory from the standpoint of public health,
welfare, or environmental quality, and, if so, refer the Final EIS to CEQ.

EPA (OFA and regional offices) reviews approximately 500 EISs and about 2,000 other actions
each year. OFA also develops guidance materials, provides NEPA and §309 training courses,
and promotes coordination between EPA offices and other federal agencies.

2.5 Energy Efficiency and the NEPA Process

Section 309 of the Clean Air Act directs the EPA to review and comment on major federal
actions significantly affecting the quality of the human environment undertaken by other federal
agencies, and to make the results of those reviews available to the public. In its Section 309 role,
EPA ensures that federal agencies give due consideration to environmental factors and resource
issues in their individual decision-making processes. EPA conducts Section 309 reviews
consistent with its Policy and Procedures for the Review of Federal Actions Impacting the
Environment (EPA 1984) and the 2007 update (EPA 2007).

While NEPA does not specifically address the subject, the promotion of energy efficiency is
inherent in the overall goals of the statute which define the environmental stewardship policy of
the nation and include the concepts of:

•  Responsibility for the future: Fulfill the responsibilities of each generation as trustee of the
   environment for succeeding generations.
•  Societal prosperity: Achieve a balance between population and resource use which will
   permit high standards of living and a wide sharing of life's amenities.
•  Sustainable practices: Enhance the quality of renewable resources and approach the
   maximum attainable recycling of depletable resources.

Under the CEQ regulations for implementing NEPA,  consideration of energy efficiency is
specifically required. Under Section 1502.16 (e) regarding the requirements for analyzing and
documenting environmental consequences, agencies are required to discuss "energy
requirements and conservation potential of various alternatives and mitigation measures."
Section 1502.16(f) requires agencies to consider the "natural or depletable resource requirements
and conservation potential of various alternatives and mitigation measures." Energy efficiency
and conservation concepts may also be interpreted as  a necessary consideration in addressing the
relationship between  short-term uses of man's environment and the maintenance and
enhancement of long-term productivity, and any irreversible or irretrievable commitments of
resources as required by the CEQ regulations (Section 1502.16).

Several executive orders and policies have been promulgated over the years that require or
promote the consideration of energy efficiency in federal actions, including the following:

•  Executive Order 13423, Strengthening Federal Environmental, Energy and Transportation
   Management (EOF 2007)
•  Executive Order 13221, Energy Efficient Standby Power Devices (EOF 2001 a)
                                         2-3                   EPA Publication No. 315-R-09-001

                                             Energy Efficiency Reference for Environmental Reviewers
•  Executive Order 13211, Actions Concerning Regulations That Significantly Affect Energy
   Supply, Distribution, or Use (EOF 200 Ib).

These executive orders are discussed in detail in Chapter 3 of this document.

The reviewer should keep in mind that questions and suggestions regarding energy efficiency
should be governed by tests of reasonableness and practicality. The earlier in the NEPA process
(e.g., during scoping) that suggestions are made and considered, the greater the likelihood of
incorporating energy efficiency in project design.  This reference is provided to help the reviewer
recognize energy impacts and considerations that  may be included in the NEPA process.  The
best time to include questions or suggestions regarding energy efficiency is during the scoping
stage or, where EPA is a cooperating agency, during the preparation of the DEIS. The intent of
this document is to increase awareness and understanding of federal programs and information
regarding energy efficiency.

This section provides background information on
the laws, regulations, Presidential directives, and
guidance relating to energy efficiency. This is not
intended to be a comprehensive compilation of
such documents; rather it is intended to assist the
reviewer by providing background information. It
is important to note that EPA does not have
jurisdiction or authority to enforce these laws,
regulations and directives.

3.1 Energy Policy Act of 2005

The purpose of the Energy Policy Act of 2005
(P.L.  109-58), the first major piece of federal
energy legislation since 1992, is to "ensure jobs
for our future with secure, affordable, and reliable
energy." The Act contains provisions to promote
energy efficiency and conservation, encourage
alternative and renewable energy sources, reduce
dependence on foreign sources of energy, increase
domestic production, modernize the electricity
grid, and encourage the expansion of nuclear
energy.

Title I, Energy Efficiency, of the 18-title act
addresses energy efficiency as it relates to Federal
Programs (Subtitle A), Energy Assistance and
State Programs (Subtitle B), Energy Efficient
Products (Subtitle C), and Public Housing
(Subtitle D). Of particular relevance to NEPA
document review, Title I, Subtitle A, Federal
Programs, amends the National Energy
Conservation Policy Act (NECPA) of 1978 by
adding:
3.1 Energy Policy Act of 2005
3.2 National Energy Conservation
   Policy Act of 1978
3.3 Criteria for Excluding Buildings

                                             Energy Efficiency Reference for Environmental Reviewers
•  A requirement for agencies to monitor their electricity use in all federal buildings by October
   1, 2012, using advanced meters or devices that provide data at least daily and that measure
   consumption of electricity at least hourly.
•  A requirement that, whenever an agency procures an energy-consuming product, they must
   purchase an ENERGY STAR or Federal Energy Management Program (FEMP)-designated
   product, unless such products would not be cost-effective (including consideration of energy
   savings) or not reasonably available. DOE published a final rule on March 13, 2009, stating
   that ENERGY STAR and FEMP-designated products may be assumed to be life cycle cost-
   effective, and identifying the applicability of NECPA Section 553 requirements related to
   energy efficiency to specific procurement actions (74 Federal Register 10830-10835, March
   13, 2009, to be codified as 10 CFR 436.40-436.43).
•  Extension of the energy savings performance contracts provision in NECPA Section 801
   through 2016.
•  Voluntary agreements between industrial energy users and federal agencies to reduce energy
   intensity (defined as "the primary energy consumed for each unit of physical output in an
   industrial process" (42 USC 15811).
•  A requirement for DOE to establish a university-led Advanced Building Efficiency Testbed
   program to develop, test and demonstrate advanced engineering systems, components and
   materials to enable innovations in building technologies, for which funds were appropriated
   for fiscal years 2006-2008.
•  Requirements for achieving greater use of recovered mineral component in cement or
   concrete projects.
•  Requirements that DOE establish regulations revising federal building energy performance
   standards that require that new federal buildings (1) are designed to achieve energy
   consumption levels that are at least 30 percent below levels established by the American
   Society of Heating, Refrigeration, and Air-conditioning Engineers (ASHRAE) Standard or
   the International Energy Conservation Code standards, (2) incorporate sustainable design
   principles; and (3) apply water conservation technologies if water is used to achieve energy
   efficiency.
•  Increasing the length of daylight  savings time.
•  In managing public lands, incorporating the use of energy efficient technologies in public and
   administrative buildings,  and using energy-efficient motor vehicles  to the extent practicable.

In Title II, Renewable Energy, Section 203 sets federal government renewable energy
consumption requirements, and prioritizes renewables  that are produced on-site or on federal or
Indian lands. Section 204 promotes the establishment of a photovoltaic  energy
commercialization program in federal buildings, including the installation of 20,000 solar energy
systems in federal buildings by 2010.

In addition to its goals for federal programs, the Energy Policy Act includes three major energy
efficiency provisions: (1) new minimum energy efficiency standards  for specific residential and
commercial products (Title 1, Subtitle C, Energy Efficient Products); (2) research into energy

3.2 National Energy Conservation Policy Act of 1978

The purpose of the National Energy Conservation Policy Act of 1978 (NECPA) is "to provide
for the regulation of interstate commerce, to reduce the growth in demand for energy in the
United States, and to conserve nonrenewable energy resources produced in this Nation and
elsewhere, without inhibiting beneficial economic growth" (42 USC 820l(b)). On their website,
DOE states that NECPA "serves as the underlying authority for federal energy management
goals and requirements. . . NECPA is the foundation of most current energy requirements" (DOE
2009).

The NEPCA energy management requirements (Subchapter III, "Federal Energy Initiative," Part
B, "Federal Energy Management," 42 USC 8251-8262k) are particularly relevant to NEPA
analyses of agency actions. This part promotes the conservation and the efficient use of energy
and water, and the use of renewable energy sources by the federal government (42 USC 8252).
As currently amended, it provides for:

•  Annual reductions in energy use at federal agency buildings (including industrial and
   laboratory facilities) through fiscal year 2015, with DOE to complete a review of the
   government's performance in response to this requirement by the end of 2014 and
   recommend additional measures for fiscal years  2016 through 2025. Installation of energy
   and water conservation measures in federally owned buildings.
•  Metering energy use in federal buildings.
•  Establishing and using life cycle cost methods and procedures.
•  Authorizing agencies to offer and receive incentives for energy efficiency improvements.
•  Implementing energy management programs in federal agencies, including
   intergovernmental energy management planning and coordination, energy management
   training, energy audit teams, energy cost accounting and management, procurement and
   identification of energy efficient products, provisions specific to the Postal Service, and
   government contract incentives.

3.3 Criteria for Excluding Buildings from the Energy Performance Requirements
of Section 543 of the National Energy Conservation Policy Act, as Amended by
the Energy Policy Act of 2005

Under Section 543 of NECPA, 42 USCA § 8353 federal agencies are required to demonstrate an
annual reduction in energy usage. A building may be excluded from this requirement for one
fiscal year if it meets all of the following criteria (DOE 2006a):

1.    Impracticability due to energy intensiveness or national security function.
2.    Completed energy management reports.
3.    Compliance with all energy efficiency requirements.
4.    Implementation of all cost-effective energy projects in the building.

Federal agencies are required to submit to DOE their aggregate annual costs for each fuel type
consumed in its excluded buildings as well as the aggregate gross square footage of the excluded
buildings. The full text of these criteria is available in paragraph (c) at:
http ://wwwl. eere. energy. gov/femp/pdfs/exclusion_criteria.pdf.

3.4 Energy Independence and Security Act of 2007

The Energy Independence and Security Act of 2007 (EISA) (P.L. 110-140) builds ontheEnergy
Policy Act of 2005 in creating a comprehensive energy strategy for the 21st century.  EISA
promotes accelerated research and development of alternative energy resources, primarily
focusing on solar, geothermal, and marine energy technologies, along with carbon sequestration.
In addition to providing research funding, the Act directs DOE to conduct studies on integration
of alternative energy technologies into regional electric transmission grids, to offer grant
programs for alternative energy workforce training, and to initiate and fund demonstration
programs for alternative energy technologies.

The Act raises corporate average fuel economy (CAFE) standards to 35 miles per gallon (mpg)
by model year 2020. Prior to EISA, Congress had not raised the CAFE standard for passenger
cars since 1975.

EISA 2007 also revises the Renewable Fuel Standard (RFS) for transportation fuels, originally
created under the Energy Policy Act of 2005. The Act seeks to increase the supply of biofuel by
requiring fuel producers to use in the fuel mix a progressively increasing amount of biofuel,
culminating in at least 36 billion gallons of biofuel by 2022. This includes 15 billion gallons of
conventional biofuel such as corn ethanol, as well as 21 billion gallons of advanced biofuels.
Within advanced biofuels, new volume standards are created for cellulosic biofuel, biomass-
based diesel, and other advanced biofuel.  EISA also includes new definitions and criteria for
both renewable fuels and the feedstocks used to produce them, including new lifecycle
greenhouse gas (GHG) emission thresholds for each type of renewable fuel mandated by the Act.
EISA requires a 50% reduction in lifecycle GHG emissions for fuels to be classified as biomass-
based diesel or advanced biofuel, and a 60% reduction in order to be classified as cellulosic
biofuel.   EISA also provides some limited flexibility for EPA to adjust these GHG percentage
thresholds downward by up to 10 percent under certain circumstances.  EPA issued a proposed
                                          3-4                EPA Publication No. 315-R-09-001

rule on May 19, 2009 to implement these changes to the RFS program, and is now working on a
final rule.  Additional details can be found at:
http://www.epa.gov/otaq/renewablefuels/index.htm

The Act also authorizes EPA to define low GHG-emitting light-duty vehicles and medium-duty
passenger vehicles and prohibits federal agencies from acquiring light-duty vehicles and
medium-duty passenger vehicles that are not low GHG-emitting vehicles.

EISA sets the first federal mandatory efficiency standards for lighting and residential and
commercial appliance equipment, including 200 percent greater efficiency from light bulbs by
2020. The array of products and appliances for which energy efficiency standards are established
in the Act includes dishwashers, dehumidifiers, residential boilers, electric motors, incandescent
lamps, external power supplies, and walk-in coolers and freezers. EISA also directs DOE to
conduct new rulemakings on residential refrigerators and clothes washers, and on the standby
power use of currently regulated appliances, and to revise all standards and test procedures on a
regular basis.

The Act also establishes requirements for federal agency efficiency and renewable energy use.
Key provisions include:

•  All general purpose lighting in federal buildings must use ENERGY STAR or FEMP-
   designated products by 2013.
•  All new federal buildings must be "carbon neutral" by 2030.
•  New and renovated federal buildings must reduce fossil fuel use by 55 percent from 2003
   levels by 2010, and 80 percent by 2020.
•  The U.S. General Services Administration (GSA) will establish an Office of High-
   Performance Green Buildings to promote green building technology implementation in
   federal buildings.

The Act also permanently authorizes Energy Savings Performance Contracts, an innovative
financing tool for upgrading the energy efficiency of federal buildings. EISA authorizes DOE to
implement a new program, the Commercial Buildings Initiative, to be designed with input from
an industry consortium. This program will combine research, development, and deployment
activities designed to achieve the goal of making all new commercial buildings "zero energy" by
the year 2030.  Zero energy means that, on a net basis, the facility produces as much energy as it
uses.

3.5 Housing and Community Development Act of 1974

The purpose of the Housing and Community Development Act, as amended, is development of
viable urban communities, by providing decent housing  and a suitable living environment and
expanding economic opportunities, principally for persons of low and moderate income (42 USC
                                          3-5                EPA Publication No. 315-R-09-001

3.6 Federal Acquisition Regulation

Title 48 of the CFR contains the Federal Acquisition Regulation (FAR), which codifies uniform
policies and procedures for federal agency acquisitions. FAR Subparts 23.200 through 23.206
prescribe procedures for acquiring products and services that are energy- and water-efficient and
products that use renewable energy technology. To meet FAR requirements, the GSA offers
products designated as energy efficient under the EPA ENERGY STAR program, U.S.
Department of Energy (DOE) FEMP, and the Green Electronics Council's Electronic Product
Environmental Assessment Tool (EPEAT).

The FAR is contained in CFR Title 48, which is available at

3.7 Federal Energy Management and Planning Programs, 10 CFR Part 436

10 CFR Part 436 "sets forth the rules for Federal energy management and planning programs to
reduce Federal energy consumption and to promote life cycle cost effective investments in
building energy systems, building water systems and energy and water conservation measures
for Federal buildings." 10 CFR 436.1.

Subpart A of the regulation "establishes a methodology and procedures for estimating and
comparing the life cycle costs of Federal buildings, for determining the life cycle cost
effectiveness of energy conservation measures and water conservation measures, and for rank
ordering life cycle cost effective measures in order to design a new Federal building or to retrofit
an existing federal building. It also establishes the method by which efficiency shall be
considered when entering into or renewing leases of federal building space" (10 CFR 436.10).

Subpart B  "provide[s] procedures and  methods which apply to Federal agencies with regard to
the award  and administration of energy savings performance contracts awarded on or before
September 30, 2003." 10 CFR 436.30.

Subpart C  "provides guidance to promote the procurement of energy efficient products by
Federal agencies and promote procurement practices which facilitate the procurement of energy
efficient products" 10 CFR 436.40.

Subpart F, Guidelines for General Operations Plans, "provide[s] guidelines for use by Federal
agencies in their development of overall 10-year energy management plans to establish energy
conservation goals, to reduce the rate of energy consumption, to promote the efficient use of

sudden disruption in the supply of oil-based fuels, natural gas or electricity. The plan is intended
to provide the cornerstone for a program to conserve energy in the general operations of an
agency" (10 CFR 436.100). Each federal agency must submit its plan or revision of a plan to
DOE. DOE is authorized to review federal agency energy management plans and to evaluate the
sufficiency of such plans. 10 CFR 436.107.

3.8 Executive Order 13423, Strengthening Federal Environmental, Energy, and
Transportation Management

Executive Order (EO) 13423, Strengthening Federal Environmental, Energy and Transportation
Management (EOF 2007), consolidates and strengthens prior energy-efficiency related executive
orders by establishing new and updated goals, practices, and reporting requirements for
performance and accountability. Federal agency goals listed in EO 13423 include:

•  Improve energy efficiency and reduce greenhouse gas emissions by 3 percent annually by the
   end of fiscal year 2015 or by 30 percent by the end of fiscal year 2015 (using 2003 as the
   baseline). At least half of the statutorily-required renewable energy must come from new
   renewable sources, which are defined as sources of renewable energy placed into service
   after January 1, 1999. (Note: The federal government improved energy efficiency 29.6
   percent between 1985 and 2005. The energy efficiency goal outlined in the EO seeks to
   achieve in 8 years (2007 to 2015) the same level of improvement that federal agencies
   achieved in the preceding 20 years, and is 50 percent more stringent than the goal in the
   Energy Policy Act of 2005 (OFEE 2009)).
•  Beginning in fiscal year 2008, reduce water consumption relative to the fiscal year 2007
   baseline by two percent annually through the end of fiscal year 2015. (Note: Prior executive
   orders related to energy efficiency did not include a water consumption goal).
•  Procure green products and services (that is, environmentally sensitive, energy efficient,
   water efficient, and recycled content, reduce use of toxic and hazardous chemicals and
   materials).  (Note: EO 13423 requires agencies to integrate four existing disparate purchasing
   requirements into an integrated federal purchasing effort that applies to all types of
   acquisitions of goods and services. Federal purchasing of energy efficient, recycled content,
   bio-based, and environmentally preferable products should increase as a  result).
•  Construct or renovate buildings in accordance with the Guiding Principles for Federal
   Leadership in High Performance and Sustainable Buildings set forth in the Federal
   Leadership in High Performance and Sustainable Buildings Memorandum of Understanding
   (MOU) (2006) (http://www.wbdg.org/pdfs/sustainable  mou.pdf).
•  If the agency operates a fleet of at least 20 motor vehicles, increase purchase of plug-in
   hybrid electric vehicles when commercially available at a cost reasonably comparable,
   reduce the fleet's total petroleum consumption by 2 percent annually through the end of
   fiscal year 2015, and increase the use of alternative non-petroleum-based fuels by 10 percent
   annually. (Note: The Energy Policy Act of 2005 also set a renewable energy goal but did not
   require that any percentage come from new sources).
                                          3-7                EPA Publication No. 315-R-09-001

                                            Energy Efficiency Reference for Environmental Reviewers
•  Ensure at least 95 percent of all purchased electronic products are Electronic Product
   Environmental Assessment Tool (EPEAT)-registered; enable the ENERGY STAR feature on
   all agency computers and monitors; establish and implement policies to extend the useful life
   of agency electronic equipment; and use environmentally sound practices with regard to the
   disposition of electronic equipment that has reached the end of its useful life. (Note: This
   goal impacts approximately $60 billion that the federal government spends annually on
   information technology-related purchases (OFEE 2009)).

In addition, the EO directs each agency head to:
•  Designate a senior civilian officer to be responsible for EO implementation.
•  Establish programs for environmental management training, environmental compliance
   review and audit, and leadership awards to recognize outstanding environmental
   performance.
•  Implement  environmental management systems (EMSs) within the agency to address
   environmental aspects of internal agency operations and activities, including energy and
   transportation functions. Use EMSs to establish agency objectives and targets for EO
   implementation and measure performance. (Note: As a result of this directive, it is projected
   that by approximately 2010, there will be at least 2,500 federal operations that implement
   EMSs, up from about 1,000 today (OFEE 2009)).
•  Establishes an Office of the Federal Environmental Executive to assist in implementation of
   the EO.

EO 13423 revoked several previous EOs, as follows:

•  EO 13101,  Greening the Government through Waste Prevention, Recycling, and Federal
   Acquisition.
•  EO 13123,  Greening the Government through Efficient Energy Management.
•  EO 13134,  Developing and Promoting Biobased Products and Bioenergy.
•  EO 13148,  Greening the Government through Leadership in Environmental Management.
•  EO 13149,  Greening the Government through Federal Fleet and Transportation Efficiency.

Because EO 13423 revokes the previous  EOs, 309 Reviewers should reference EO 13423 when
offering energy efficiency recommendations on related topics.  The full text of this EO can be
accessed at http://edocket.access.gpo.gov/2007/pdf/07-374.pdf

3.9 Executive Order 13221, Energy Efficient Standby Power Devices

The EO requires that a federal agency, each time "it purchases commercially available, off-the-
shelf products that use  external standby power devices, or that contain an internal standby power
function, shall purchase products that use no more than one watt in their  standby power
consuming  mode" (EOF 200la). If such products are unavailable, agencies are to purchase
products with the lowest standby power wattage while in their standby power consuming mode.
DOE, in consultation with the Department of Defense and the GSA, was directed to compile an
annual list of products subject to these requirements.

3.10 Executive Order 13211, Actions Concerning Regulations That Significantly
Affect Energy Supply, Distribution, or Use

When undertaking "significant energy action," (that is, an action by an agency normally
published in the Federal Register that promulgates or is expected to lead to the promulgation of a
final rule or regulation that (1) is a significant regulatory action under EO 12866 and is likely to
have a significant adverse effect on the supply, distribution or use of energy; or (2) is designated
by the Administrator of the Office of Information and Regulatory Affairs (OIRA) within the
Office of Management and Budget, as a significant regulatory action), an agency must prepare,
to the extent permitted by law, a Statement of Energy  Effects.  The Statement consists of a
detailed statement relating to (1) any adverse effects of the regulatory action on energy supply,
distribution, or use; and (2) reasonable alternatives to the action and the expected effects of such
alternatives on energy supply,  distribution and use (EOF 200Ib). The Statement is to be
submitted to the Administrator of OIRA and published in each related proposed rulemaking and
in any resulting final rule.

3.11 Guidance for Electric Metering in Federal Buildings
Section  103 of the Energy Policy Act of 2005  amended section 543 of the National Energy
Conservation Policy Act (see section 3.3), 42 USC 8253, and requires agencies to measure
electricity use in all federal buildings by October 1, 2012, using advanced meters or devices that
provide  data at least daily and that measure at least hourly consumption of electricity. Guidelines
for implementing this requirement, developed by DOE (2006b), clarified that the requirement
applies only to electric metering and that it applies to all electric metering at all federal buildings
based on cost-effectiveness and practicability. DOE required agencies to submit implementation
plans by August 3, 2006, and to begin reporting annually on their progress beginning with FY
2007. The statute requires agencies to install meters, to the maximum extent practicable, by
October 1, 2012. The guidance defines "Advanced Metering," describes the uses of metered
data, identifies metering approaches and technologies, discusses how to determine cost-
effectiveness of metering, presents methods for prioritizing buildings for metering applications,
discusses methods of financing metering equipment, provides a template for an agency metering
plan, and discusses performance measures and special considerations.

A summary of voluntary energy efficiency (and climate
change) related federal and state programs are provided on
EPA's website:
http://yosemite.epa.gov/gw/StatePolicyActions.nsf/VolProg?OpenView&count=1000. More
than 150 programs are listed.

4.1 Federal Energy Management Program

The DOE Office of Energy Efficiency and Renewable Energy (EERE) manages the Federal
Energy Management Program (FEMP),  one often EERE programs dedicated to supporting
efficient and renewable energy technologies. FEMP concentrates the federal government's
influence as the largest energy consumer in the U.S. to promote energy efficiency and the use of
renewable energy resources at federal sites. The program has also published guidance for
agencies, with several documents available under each of the following topics; see DOE (2009a):

•   General Guidance for Facilities
•   Advanced Metering
•   Energy-Efficient Products
•   Fleet Management
•   Sustainable Building Design and Operation
•   Water Efficiency
•   Renewable Energy Technologies

The program's services are broadly divided into project transaction services, applied technology
services, and decision support services,  as described below. The following information on
program details  is consolidated from the FEMP web site (DOE 2006a).

FEMP Project Transaction Services

FEMP supports  federal agencies through coordinating financing assistance for energy efficiency
and renewable energy projects. Alternative financing tools include:

•   Energy Savings Performance Contracts (ESPCs) ESPCs allow federal agencies to
    accomplish energy savings projects without up-front capital costs and without special
    Congressional appropriations.  An ESPC is a partnership between a federal agency and an
                                          4-1                 EPA Publication No. 315-R-09-001

-------
                                                                            March 2010
                                         Energy Efficiency Reference for Environmental Reviewers
   energy service company (ESCO). The ESCO conducts a comprehensive energy audit for the
   federal facility and identifies improvements to save energy. In consultation with the agency,
   the ESCO designs and constructs a project that meets the agency's needs and arranges the
   necessary financing. The ESCO guarantees that the improvements will generate energy cost
   savings sufficient to pay for the project over the term of the contract. After the contract ends,
   all additional cost savings accrue to the agency. Contract terms up to 25 years are allowed.

•  Utility Energy Services Contracts (UESCs) Federal agencies can enter into utility energy
   service contracts (UESCs) to implement energy improvements at their facilities. With a
   UESC, the utility typically arranges financing to cover the capital costs of the project. Then
   the utility is repaid over the contract term from the cost savings generated by the energy
   efficiency measures. Agencies can implement energy improvements with no initial capital
   investment, the net cost to the agency is minimal, and the agency saves time and resources by
   using the one-stop shopping provided by the utility. The Energy Policy Act of 1992
   authorizes and encourages federal agencies to participate in utility energy  efficiency
   programs offered by utilities and by other program administrators (such as state agencies).
   These programs range from equipment rebates (that is, utility incentives) to delivery of a
   complete turnkey project.

•  Energy Efficiency and Demand Response Programs Most states have energy incentive
   programs that help offset energy  costs while promoting energy efficiency and renewable
   energy technologies. These programs include:

       o  Energy Efficiency and Renewable Energy Programs:
              •  Public  purpose programs administered by utilities, state agencies, or other
                 third parties and paid for by utility ratepayers, typically through a non-
                 bypassable system benefits charge that is instituted  as part of restructuring
                 legislation or rules. The term  "non-bypassable" means that full responsibility
                 for a distribution fee cannot be bypassed by a customer switching fuels.  A
                 system benefits charge is designed to fund certain "public benefits" that are
                 placed  at risk in a more competitive industry. These benefits include
                 assistance for low-income consumers, renewable energy research and
                 development, and energy efficiency.
              •  Utility  programs administered by the local utility and paid for by utility
                 ratepayers through their bundled rates.
              •  Programs sponsored by state agencies that are designed to promote energy
                 efficiency and renewable energy and that are usually funded out of general tax
                 revenues.
       o  Demand Response/Load Management Programs, which are programs that provide
          incentives to curtail demand during peak energy usage periods in response to system
          reliability or market conditions.

FEMP researches these programs on a state-by-state basis to help agencies meet their energy
management goals. FEMP has compiled data on the energy efficiency and renewable energy
funds and demand response programs available in each of the 50 states and the District of
Columbia; see DOE (2009b).
                                           4-2                 EPA Publication No. 315-R-09-001

                                         Energy Efficiency Reference for Environmental Reviewers
With assistance from FEMP, the federal government's commitment to improving agency energy
efficiency has accelerated and grown in recent years. ESPCs under development are now in
excess of $1 billion dollars for the first time in the program's history. The current value of the
project pipeline is over three times the size that it was in February 2007, and continues to grow.

FEMP Applied Technology Services

FEMP lends considerable research and market experience to help federal agencies deploy
technology projects, including:

•  High-Performance Building Design, Operation, and Maintenance FEMP helps agencies
   create and implement sustainable design, operation, and maintenance practices that
   incorporate energy efficiency, renewable energy, and water conservation technologies. These
   practices span new construction, renovation, and commissioning projects. FEMP services in
   this area include energy audits, operations and maintenance assessments, laboratory design
   protocols, new technology reports, advanced metering, and guidance for purchasing energy-
   efficient products and renewable energy technologies. One program example is FEMP's
   Laboratories for the 21st Century (Labs21) partnership with the EPA, which reduces federal
   laboratory energy use by $18 million annually.

•  Renewable Energy Technology Deployment FEMP assists federal agencies in developing
   and implementing solar, wind, biomass, and geothermal energy sources to meet energy
   management regulations and goals.

•  Energy-Efficient Product Procurement FEMP provides energy efficiency requirements,
   guidance, and cost calculators that help agencies offset energy consumption costs through
   energy-efficient product implementation. Federal buyers are required by the Energy Policy
   Act of 2005 to purchase products that are ENERGY STAR®-qualified or FEMP-designated
   for energy efficiency and low standby power. These products are in the upper 25% of energy
   efficiency in their class.

•  Managing Energy-Efficient/Alternative Fuel Vehicles FEMP provides  guidance and
   assistance on implementing and managing energy-efficient and  alternative-fuel vehicle fleets.
   This includes helping federal agencies meet new fleet management mandates, such as recent
   requirements for agencies to reduce petroleum consumption by 2% per year through fiscal
   year (FY) 2015 relative to a FY 2005 baseline and to increase alternative fuel use by 10% per
   year relative to the previous year. EISA 2007 (Section 141) defined low GHG-emitting
   vehicles as AFVs for the purposes of compliance with federal mandates.

FEMP Decision Support Services

FEMP assists federal agencies with guidance, outreach, and training programs that include:

•  Energy Legislation and Regulation Compliance EO 13423 established energy efficiency
   goals for federal agencies, including a 30% reduction in energy  intensity,  a significant
                                          4-3                EPA Publication No. 315-R-09-001

                                         Energy Efficiency Reference for Environmental Reviewers
   increase in the use of new renewable energy resources, and a 16% reduction in water
   consumption by fiscal year 2015.  The Energy Independence and Security Act of 2007
   codified much of EO 13423 into statute (see Section 3.4). FEMP analyzes federal legislation
   to help agencies comply with energy management requirements. This assistance is delivered
   through interagency coordination, guidance documents, facility reporting requirements, and
   fleet reporting requirements.

•  Education and Training on Energy Efficiency and Renewable Energy Federal agencies
   learn to implement energy-saving strategies, gain recognition for outstanding achievements,
   and keep current on the government's progress in meeting energy management goals through
   FEMP training, services, and outreach activities. FEMP education, training, and outreach
   programs include online news, ongoing training and events, awards, and  outreach.

FEMP at DOE Facilities: Transformational Energy Action  Management (TEAM)

At its own facilities, DOE uses the TEAM  Initiative, which seeks to attain the following specific
goals (DOE 2009c):

   1. Reduce energy consumption by 30% and water consumption by  16% in all DOE
      facilities.
   2. Acquire at least 7.5% of all energy  from renewable sources.
   3. Build alternative fueling stations on all sites by 2008, and replace all  conventional fuel
      vehicles in the DOE fleet with alternative fuel vehicles by 2010.
   4. Attain a Leadership in Energy and Environmental Design (LEED®) Gold standard on all
      new buildings and on all buildings that go through major renovations.
   5. Attain a LEED® Gold standard on 15%  of all current buildings by the end of fiscal year
      2015.
   6. Give preference to bio-based, environmentally-friendly sources of energy and water,
      while reducing the use of hazardous and toxic chemicals and managing the production of
      waste.
   7. Develop best-practice models for the use of third-party financing for  energy saving
      projects.
   8. Improve the energy efficiency of all data centers by 10% by 2011.

From 1978 through FY 2007, DOE used the Departmental Energy Management Program
(DEMP) to help rank retrofit projects, provide financial and technical  support, offer counsel for
leveraging appropriated funds with private sector financing, and ensure  compliance with
executive orders and legislation (DOE 2006b). As  of FY 2008,  energy management at DOE was
integrated with the FEMP.

4.2 EPA Programs

Combined Heat and Power Partnership

Combined heat and power (CHP) is a proven technology that utilizes indigenous heat in
buildings to generate electricity and heat either sequentially or simultaneously. In a single,
                                          4-4                EPA Publication No. 315-R-09-001

                                          Energy Efficiency Reference for Environmental Reviewers
integrated system, CHP utilizes one fuel source (such as natural gas, biomass, biogas, coal, waste
heat or oil) to produce both electricity and heat, thereby saving the energy that would have been
necessary to produce them separately. While a CHP system consists of a number of individual
components (such as heat engine, generator, heat recovery, and electrical interconnection), the
type of heat engine equipment that drives the overall system, known as the prime mover,
typically identifies the type of CHP system. Prime movers can include reciprocating engines,
combustion or gas turbines, steam turbines, micro-turbines, and fuel cells. They are capable of
burning numerous fuel types.

       Utilizing CHP for at least a portion of the electric load avoids off-site power generation
and the resultant significant losses realized from the production, transmission and distribution of
traditional power sources. CHP provides reliable power that increases production, delivery and
usage efficiencies.  Because electric generation in the US contributes significantly to the
emissions of air pollutants and GHG (responsible for 41% of the energy-related CO2 emissions),
heightened focus has been placed on improving fuel conversion efficiencies and reducing these
emissions (EIA 2009).  CHP provides a unique opportunity to dramatically impact these
efficiencies (up to 80% efficiencies when compared to separate heat and electricity production).

       The CHP Partnership (CHPP) was established in 2001  to promote the potential energy,
environmental and economic benefits of shifting traditional centralized, electric-only generation
to more distributed generation of both electricity  and heat.  CHPP is a voluntary program aimed
at heightening the awareness of the environmental, economic,  and energy benefits associated
with the various applications of this technology.  This awareness is raised by a cadre of outreach
and analytical  activities including:

•  Project Assistance including on-line qualification tools that assist facility owners/operators to
   assess the potential for CHP at their site (CHP Emissions Calculator), up-to-date lists of state
   and federal incentives for CHP, as well as information on state policies and favorable utility
   rates for CHP projects;
•  Technical Assistance— Level One Feasibility  Studies determine preliminary  technical and
   economic compatibility such as system sizing based on anticipated thermal  and electric
   loads, and  estimated turnkey costs associated with the system including equipment,
   construction, utility interconnection, implementation, as well as operation and maintenance
   costs;
•  Technical Assistance— Level Two Feasibility Studies is an Investment Grade Feasibility
   Study that  produces detailed and verifiable analyses to determine technical and economic
   viability, replacing assumptions made in Level One analyses with actual electrical,
   mechanical and structural data as well as project economic analyses including utility rate
   analyses, life-cycle costs analyses, and operation and maintenance pricing estimates. These
   analyses produce verified data to identify optimal CHP system configuration and sizing,
   appropriate thermal applications and economic operating strategies;
•  Market Analyses to assess potential  for CHP in a variety of market sectors and applications;
•  Education  and Outreach via website (www.epa.gov/chp), webinars, conferences and
   meetings, fact sheets and other documentation, as well as partnership meetings; and
                                           4-5                 EPA Publication No. 315-R-09-001

•  Public Recognition via the ENERGY STAR CHP Awards provided to CHPP Partners who
   have achieved exemplary reductions in energy usage and emissions utilizing CHP
   technology.

Partners represent a cross-section of the industry including CHP manufacturers, developers, end-
users, as well as non-profit and local government entities. For further information, visit:
www.epa.gov/chp (EPA 2008a).

Green Power Partnership

Green power is electricity produced from a subset of renewable resources, such as solar, wind,
geothermal, biomass, and low-impact hydropower (EPA 2009a). EPA's Green Power
Partnership is a voluntary program that supports the organizational procurement of green power
by offering expert advice, technical support, tools, and resources. The program can help an
organization lower the transaction costs of buying green power, reduce its carbon footprint,  and
communicate its leadership to key stakeholders. To join, an organization must submit a
Partnership Agreement and complete a qualifying green power purchase within six months of
joining the program.  After joining, the organization is required to report their green power
purchase information on a yearly basis to EPA. For more information, visit
www. epa. gov/greenpower.

ENERGY STAR

ENERGY STAR (EPA 2009b) is a joint EPA/DOE program designed to identify and promote
energy-efficient products, including office equipment, major appliances, lighting, home
electronics, new homes, and commercial and industrial buildings. Together with the
complementary DOE-managed FEMP energy-efficient product designation, ENERGY  STAR
guides federal agencies in procuring energy-efficient products and services (see Section 5.1,
Appliances and Equipment).

EPA also uses the ENERGY STAR program to support programs that improve energy use at
water utilities. Water efficiency and energy efficiency are closely linked, as water requires a
significant amount of energy input for treatment, pumping, heating, and process uses (EPA
2009c).

SmartWay Transport Partnership

The SmartWay Transport Partnership is an EPA program designed to reduce GHG emissions and
promote low carbon use and efficiency in the freight transportation system.  SmartWay provides
metrics to identify more efficient transportation choices by mode and by individual
transportation provider.  EPA also uses the SmartWay program to reduce CC>2, NOx, and PM
emissions from the transportation system. EPA also identifies the cleanest, most efficient
passenger vehicles and heavy commercial tractor-trailers, with its SmartWay designation (EPA
2009f).

National Action Plan for Energy Efficiency

Since 2005, EPA and DOE have sponsored the National Action Plan for Energy Efficiency. The
Action Plan's Leadership Group of more than 60 leading gas and electric utilities, state utility
regulators and energy offices, energy users, environmental groups, and others released five
consensus policy recommendations in 2005. The five key policy recommendations of the Action
Plan include recognizing energy efficiency as  a high-priority energy resource,  committing to the
implementation of cost-effective energy over the long-term, communicating efficiency benefits
and opportunities, providing sufficient and stable program funding, and modifying ratemaking
policies to align utility and customer incentives with investments in energy efficiency (EPA
2009d). Over 120 organizations have endorsed these recommendations and made commitments
to energy efficiency through the Action Plan.

National Action Plan Vision for 2025: A Framework for Change

The Plan was updated in 2008 with the National Action Plan Vision for 2025:  A Framework for
Change (EPA 2008b), which outlined ten specific implementation goals to achieve the major
recommendations in the original action plan, as follows:

   1.  Establish cost-effective energy efficiency as a high-priority resource.
   2.  Develop processes to align utility  and other program administrator incentives such that
       efficiency and supply resources are on a level playing field.
   3.  Establish cost-effectiveness tests.
   4.  Establish evaluation, measurement, and verification mechanisms.
   5.  Establish effective energy efficiency delivery mechanisms.
   6.  Develop state policies to ensure robust energy efficiency practices.
   7.  Align customer pricing and incentives  to encourage investment in energy efficiency.
   8.  Establish state of the art billing systems.
   9.  Implement state of the art efficiency information sharing and delivery systems.
   10. Implement advanced technologies.

The Action Plan offers a comprenhensive suite of best practices-based guides, papers and tools.
In addition, EPA and DOE offer technical assistance to states working to advance the Action
Plan Vision.

GSA Energy Division

The GSA Energy Division offers information and programs to reduce federal utility costs and
increase energy efficiency (GSA 2009b). The Center provides:

•    Web-based access to energy use data, to policy information, and to programs and contacts
     for purchasing utilities/energy and energy-related services.
•    The Public  Utilities program, which develops contracting vehicles for agencies to procure
     utility services at the lowest cost.
•    The Natural Gas Acquisition program, a new program to provide federal facilities with
     natural gas  supply and supply management.
•    The Energy and Water Management program, which is responsible for the utility use and
     cost data in all GSA buildings nationwide.

More information on GSA's energy contract information and guidebooks can be found at their
website: www.gsa.gov/energy.

Office of Federal High-Performance Green Buildings

In 2008, GSA established an Office of Federal  High-Performance Green Buildings to coordinate
green building information and activities within the federal government (GSA 2008). The office
works in conjunction with DOE, which has a similar responsibility for commercial buildings.
The duties of the office, as outlined in EISA 2007, are to establish a Federal Green Building
Advisory Committee; identify and develop technical standards for high-performance green
buildings; establish green practices for operations and maintenance of facilities; provide
information and disseminate research results; identify practices and tools to achieve high-
performance green buildings through budgeting and contracting; identify opportunities to
demonstrate innovative technologies and concepts; and, identify incentives to encourage high-

4.4 Energy Audits/Surveys

As noted in Section 4.3, contractor-provided energy audit/survey services are available to federal
agencies through a GSA multiple award schedule. The goal of an energy audit is usually to
identify opportunities to conserve energy without affecting the building or system's intended
function and desired status. GSA states that "Energy audits may range from cursory to
comprehensive. At a minimum, audits shall include data collection, data analysis, benchmarking
with tools such as Energy Star, and written recommendations of suggested upgrades of electrical
and mechanical infrastructure, including their impact on energy consumption and pollution"
(GSA 2009c).

There are many resources and no standard protocols for energy audits. An example protocol for
industrial facilities was published by Bonneville Power Administration, whose Industrial Audit
Guidebook (BPA 2004) for performing walk-through energy audits. For homeowners, both DOE
and EPA provide information on do-it-yourself and professional energy audits on their websites
(DOE 2009d, EPA 2009e).

4.5 American Recovery and Reinvestment Act (ARRA) programs

The 2009 American Recovery and Reinvestment Act (ARRA) provides substantial funding to
improve energy efficiency at federal government facilities and within vehicle fleets, as well as
research into energy efficiency technologies and improvements to the nation's energy
transmission, distribution and production systems.  Much of the funding provided in the
legislation will be distributed through existing federal programs. For example, 20% of EPA's
Clean Water and Drinking Water State Revolving Fund (SRF) grants will be spent on energy
efficiency and other green projects.  SRF grants provide low-cost financing to communities for
the construction, repair, and rehabilitation of drinking water systems and wastewater collection
and treatment facilities. SRF programs conduct an environmental review process with
similarities to the NEPA process. More information on the program can be found at:
http://www.epa.gov/safewater/dwsrf/index.html.

5.1.a Summary

Appliance and equipment purchases can be a
significant source of energy savings for federal
agencies. Purchases of appliance and equipment are
guided by several pieces of federal legislation.
EPAct 2005 amended NECPA by requiring federal
agencies to procure ENERGY STAR-qualified or
FEMP-designated products, unless the head of the agency determines in writing that a statutory
exception applies, or the product is  for combat or combat-related missions. NECPA was further
amended by EISA 2007 to clarify that the procurement requirement applies to the procurement
of a product in a category covered by  the ENERGY STAR program or the FEMP program (see
Chapter 3).

ENERGY STAR is a joint EPA/DOE program designed to identify and promote energy-efficient
products, including office equipment, major appliances, lighting, home electronics, new homes,
and commercial and industrial buildings. FEMP is a complementary DOE program that provides
an energy-efficient product designation. Products designated under ENERGY STAR and FEMP
are in the upper 25% of energy efficiency in their class.

Further, each federal agency is required to incorporate into the specifications of all  procurements
involving energy-consuming products and systems, and into the factors for evaluation of offers
received for such procurements, criteria for energy efficiency that is consistent with the criteria
used for rating ENERGY STAR qualified products and for rating FEMP designated products.

FAR Subpart 23.2 prescribes procedures for acquiring products and services that are energy- and
water-efficient and use renewable energy technology. To meet FAR requirements, the GSA
offers products designated as energy efficient under ENERGY STAR, FEMP and the Green
Electronics Council's Electronic Product Environmental Assessment Tool (EPEAT).  These
three major programs guide federal  government procurement  of energy-efficient products and
services.

EPAct 2005 required a DOE rulemaking to set standards for nine additional product categories
(Table 5-2). In April 2009, DOE published a final rule to promote federal procurement of
energy-efficient products. The final rule establishes guidelines for federal agencies in procuring
ENERGY STAR qualified and FEMP-designated products:
http://edocket.access.gpo.gov/2009/E9-5459.htm.

The guidelines apply to general specifications, project specifications, and construction,
renovation and service contracts that involve the procurement of covered products. Agencies
should consider this requirement to apply to:
     Design, design/build, renovation, retrofit and services contracts;
     Facility maintenance and operations contracts;
     Energy savings performance contracts and utility energy service contracts; and
     If applicable, lease agreements for buildings or equipment, including build-to-lease
     contracts, such as those used to implement the Military Housing Privatization Initiative.

Agencies are also encouraged to use ENERGY STAR and FEMP designated products in new
service contracts and other existing service contracts as they are recompeted and should, to the
extent possible, incorporate such requirements and preferences into existing contracts as they are
modified or extended through the exercise of contract options.

A list of product categories, which contain ENERGY STAR qualified and FEMP designed
products, is located at: http://www.eere.energy.gov/femp/pdfs/eep_productfactsheet.pdf(F£MP
Energy-Efficient, Water Conserving & Low Standby Power Product Types Product Fact Sheet).
To identify actual products that are ENERGY STAR rated, potential purchasers can go to the
ENERGY STAR website: http://www.energystar.gov/products. Currently, there is no companion
list of FEMP designated products, but the FEMP specifications for energy efficiency products
are located at: http://www.eere.energy.gov/femp/procurement/eep requirements.html. Life-
cycle cost calculators for many  of the ENERGY STAR qualified and FEMP designated products
can be accessed at: http://www.eere.energy.gov/femp/procurement/eep eccalculators.html (DOE
2009).

EO 13514 (2009) establishes the goal that 95 percent of new contract actions including task and
delivery orders, for products and services with the exception of acquisition of weapon systems,
will be ENERGY STAR, FEMP,  and/or EPEAT certified (as well as water-efficient, biobased,
non-ozone depleting, contain recycled content, or are non-toxic or less toxic alternatives), where
such products and services meet agency performance requirements. The EO also directs federal
agencies to: 1) establish and implement policies to enable power management, duplex printing,
and other energy-efficient or environmentally preferable features on all eligible agency
electronic products, 2) employ environmentally sound practices with respect to the agency's
disposition of all agency excess or surplus electronic products,  and 3) implement best
management practices for energy-efficient management of servers and Federal data centers.

EO 13221 requires that federal  agencies purchase products with low standby power (see Chapter
3). Standby power is electricity used by appliances and equipment while they are switched off or
not performing their primary function. Most products with an external power supply, remote
control, continuous display (including an LED), or charges batteries will draw power
continuously. Standby mode is different than "sleep" mode. All ENERGY STAR labeled
computers, monitors, copiers, printers, and fax machines will switch into a low-power "sleep"
mode after a specified  period of non-use. When needed, these devices return automatically to the
active mode (displaying an image, copying, receiving a fax etc.) after a brief delay. Standby
mode is different because the user—not the machine itself—has switched off the device and
must manually turn it back on.  Power use in the standby mode is usually much lower than in the
sleep mode.

EO 13221 directs agencies, when feasible and cost effective, to purchase products that use 1 watt
of power or less during standby mode. Both ENERGY STAR and FEMP have specifications for
products that meet this standby  power guideline (FEMP 2002).

The  1997 Federal ENERGY STAR Buildings Program Partnership Memorandum of
Understanding between DOE, EPA, and DoD requires the military to survey energy-efficient
building upgrades, and implement them to the maximum extent practicable using the full range

5.1.b Related Federal Partnership Programs

ENERGY STAR

EPA introduced the ENERGY STAR program in 1992 as a way to reduce greenhouse gas
emissions through greater energy efficiency. Today, in partnership with DOE, the ENERGY
STAR program defines energy efficiency standards for a variety of products and services, and
qualifies specific products as meeting the ENERGY STAR standards (DOE 2009e). EPA
oversees the ENERGY STAR Program and manages ENERGY STAR efforts to make existing
homes, new homes and commercial and industrial buildings more energy efficient. The goals of
the program are to provide businesses and consumers with objective information and tools to
make informed decisions about equipment purchases; and to assist in reducing business
investment risks for implementing energy efficiency projects. The program also provides a
market-based mechanism to reduce greenhouse gas emissions.

One of the best known energy efficiency federal programs,  ENERGY STAR labeling is
recognized by more than 75% of the American public. Figure 5-1  shows the expected emissions
reductions from the ENERGY STAR program through 2012.

The program was first introduced as a voluntary labeling program designed to identify and
promote energy-efficient computers to reduce greenhouse gas emissions. The ENERGY STAR
label has since been expanded to cover more than 60 product categories, including appliances,
office equipment, lighting, heating and cooling equipment, home electronics, and new homes and

commercial and industrial buildings (DOE 2009e).  Together with the complementary DOE
Federal Energy Management Program (FEMP) energy-efficient product designation, ENERGY
STAR guides federal government procurement of energy-efficient products and services.

ENERGY STAR products can be found on the ENERGY STAR website:
http ://www. energystar. gov.  EPA routinely monitors the use of the label on products in the
market place to ensure that it is used to identify only qualified products. EPA also selectively
tests products to ensure that products said to qualify for the label do indeed qualify.  The
performance specifications for ENERGY STAR are updated as market conditions change.

EPA's ENERGY STAR Portfolio Manager is a national energy performance rating  system for
buildings. It functions as an interactive energy management tool that can be used to track and
assess energy and water consumption.  The types of buildings eligible to receive a rating include:

•  Bank/Financial Institutions            •   Municipal Wastewater Treatment Plants
•  Courthouses                          •   Offices
•  Hospitals (acute care and children's)    •   Residence Halls/Dormitories
•  Hotels                               •   Retail Stores
•  K-12 Schools                         •   Supermarkets
•  Medical Offices                      •   Warehouses (refrigerated and non-refrigerated)

Statistically representative models are used to compare each building against buildings with
similar characteristics from a national survey conducted by DOE's Energy Information
Administration (EIA). This national survey, known as the Commercial Building Energy
Consumption Survey (CBECS), is conducted every four years, and gathers data on building
characteristics and energy use from thousands of buildings across the United States. A rating of
75 indicates that the building performs better than 75% of all similar buildings nationwide.
Buildings rating 75 or greater may qualify for the ENERGY STAR label. This rating can be
used in key market transactions such as the assessment of a building's asset value or the lease
price of building space.

For those buildings that are not eligible to receive a rating, EPA has created  a list of reference
energy performance targets (EPA 2009b). These are based on average energy use calculated
across different types of buildings. These energy performance targets are not normalized for
climate nor adjusted for activities which may affect energy use. All targets are expressed in
energy use intensity and are derived from the Commercial Buildings Energy Consumption
Survey.

EPA also uses the ENERGY STAR program to support programs that improve energy use at
water utilities. Water efficiency and energy efficiency are closely linked, as water requires a
significant amount of energy input for treatment, pumping, heating and process uses. ENERGY
STAR recently added wastewater and drinking water treatment facilities to the suite of facilities
addressed under its Portfolio Manager. The Portfolio Manager can help a utility to set targets for
investment priorities, verify efficiency improvements, and calculate its carbon footprint.

ENERGY STAR also offers tools and information for residential homeowners and new home
builders.  Residential homeowners can get assistance in performing a home energy audit, and
retrofitting their property for greater energy efficiency. The Home Performance with Energy
Star Program offers a comprehensive, whole-house approach to improving energy efficiency,
ventilation, Indoor Air Quality and comfort at home
(http://www.energystar.gov/index.cfm7cHiome improvement.hm improvement hpwes).
New home builders can have properties qualified with the ENERGY STAR label. ENERGY
STAR labeled new homes are at least 15% more energy efficient than homes built to the 2004
International Residential Code (IRC), and include additional energy-saving features that
typically make them 20-30% more efficient than standard homes. Approximately 12% of U.S.
new housing starts in 2007 were qualified as ENERGY STAR homes (EPA 2008). The U.S.
Army Corps of Engineers (USAGE) builds all new Army homes as ENERGY STAR properties.
EPA also supports HUD in its integration of ENERGY STAR into home energy programs and
other affordable housing efforts (EPA 2003).

Electronic Product Environmental Assessment Tool (EPEAT)

The Electronic Product Environmental Assessment Tool (EPEAT) is a system that evaluates
electronic products (mainly computers and computer products) based on 51 environmental
criteria related to the reduction/elimination of environmentally sensitive materials, materials
selection, design for and management of product end of life, product longevity/life cycle
extension, energy conservation, corporate performance and packaging.  There are 23 required
criteria and 28 optional criteria. To qualify for registration as an EPEAT product, the product
must conform to all the required criteria.  Table 5-3 lists the titles of each of the 51 criteria.
Detailed summaries of the each of the criteria can be found  at:
http://www.epeat.net/Docs/Summarv%20of%20EPEAT%20Criteria.pdf.

EPEAT evaluates electronic products according to three tiers of environmental performance -
Bronze, Silver and Gold.  To be EPEAT registered at the Bronze level, products must meet all the
51 required criteria. Products may then achieve a silver or gold level EPEAT rating by meeting
all required criteria plus at least 50% or 75%, respectively, of the optional criteria that apply to
the product type being registered.

EPEAT is managed and operated by staff from the Green Electronics Council (GEC). The GEC
is part of the 501(c)(3) non-profit International Sustainable Development Foundation. The
EPEAT system was originally developed in a two-year multi-stakeholder process that was
facilitated by the Zero Waste Alliance on a EPA grant. The criteria listed in EPEAT are
contained in environmental performance standard IEEE 1680.  IEEE is an international
organization (originally an acronym for Institute of Electrical  and Electronics Engineers, Inc.)
that provides technical and professional information. IEEE 1680 includes a criterion (4.5.1.1)
that requires that every EPEAT registered product meet the  current version of the applicable
ENERGY STAR standard.

The EPEAT Registry web site: http://www.epeat.net/ lists products in conformance with EPEAT
criteria. On the website, purchasers can use the EPEAT database to search for EPEAT registered
products and review product-specific information, and can use the Electronics Environmental

DOE's FEMP helps federal purchasers identify products in the top 25   percentile of efficiency
for their class and that use minimal standby power in accordance with EO 13221.  The FEMP
designation is useful for products that have yet to be assigned an ENERGY STAR certification.
The FEMP also provides model language for specifying efficient products in capital projects and
service contracts, and gives buyers advice on procurement decisions. FEMP publishes a series of
Purchasing Specifications  for Energy-Efficient Products:
www.eere.energy.gov/femp/procurement/. For each product, FEMP identifies the efficiency
levels needed to meet the requirements for procurement of energy-efficient products. Whenever
there is a significant change in the market, FEMP revises the energy efficiency levels to a
market-leading threshold and updates the specifications. To assist federal buyers in identifying
qualifying products, the FEMP Procurement Web site provides links to lists of models that meet
the required efficiency levels. These lists identify efficient models by brand name and model
number (EPA 2009a).

                                         Energy Efficiency Reference for Environmental Reviewers
Over the past two decades, Congress, in various energy efficiency related legislation, set the
initial federal energy efficiency standards for many major appliances and established schedules
for DOE to review and revise these standards (DOE 2009a). The Appliance and Commercial
Equipment Standards Program (Equipment Standards and Analysis), which operates within the
Building Technologies Program (see Table 5-3), maintains and updates these standards and the
testing procedures for  appliances and equipment referenced in federal legislation.  DOE is
required to upgrade standards to the maximum level of energy efficiency that is technically
feasible and economically justified.

The program carries out activities in three areas: 1) maintaining federal mandatory energy
conservation standards to achieve national consistency; 2) outlining test procedures that
manufacturers must use to certify that their appliances meet the standards (test procedures are
typically maintained by industry associations and incorporated by reference into DOE rules); and
3) labeling commercial equipment, a shared responsibility with the Federal Trade Commission
(FTC).

EPA Sector Notebooks

The Sector Notebook series is a unique set of profiles containing information for specific
industries  and governments. Unlike other resource materials, which are organized  by air, water,
and land pollutants, the Notebooks provide a holistic approach by integrating processes,
applicable regulations  and other relevant environmental information. There are 33  Industry
Sector Notebooks and  3 Government Series that provide government officials with information
they need to comply with the environmental regulations that apply to their activities. Many of
them may provide useful information for the NEPA reviewer.  More information about the
Sector Notebooks can  be found in  the Sector Notebook Factsheet located at:
http://www.epa.gov/compliance/resources/publications/assistance/sectors/notebooks/sector-
notebooks-factsheet.pdf. The notebooks can be accessed at:
http://www.epa.gov/compliance/resources/publications/assistance/sectors/notebooks/.

State Energy Program

The DOE  State Energy Program (SEP) funds states to carry out their own energy efficiency and
renewable energy programs. The states can tailor projects to meet individual needs, economic
conditions, climate, and renewable resources. DOE technical assistance helps states develop
projects and accelerate the adoption of energy efficiency technologies.  DOE investment in SEP
is augmented by funding from state and local governments and the private sector.  SEP also
directs funding from EERE technology programs to the states for specific projects to advance the
adoption of emerging energy technologies (DOE 2009c).

Rural Energy for America Program

The Rural Energy for America (REAP) program was created through the 2008 Farm Bill, and
provides financial assistance to agricultural producers and rural small businesses to purchase
renewable energy systems or make energy efficiency improvements (e.g., replacing equipment

5.1.c Review Considerations

309 Reviewers should identify whether energy efficiency requirements are addressed in EISs.  It
is understood that rather than repeating a lengthy discussion on these requirements, the EISs will
most likely incorporate them by reference by citing the appropriate document. Many times these
documents are made available via a link to a web site in the EIS. In  most cases, this should
suffice.

Reviewers should look for whether discussions that address federal agency actions related to
general specifications, project specifications, and construction, renovation and service contracts
that involve the procurement of energy-consuming products and systems are in compliance with
EPAct 2005, EISA 2007, EO 13423, EO 13514 and EO 13221:

•    EPAct 2005 requires that, whenever an agency procures an energy-consuming product,
     they must purchase an ENERGY STAR or Federal Energy Management Program (FEMP)-
     designated product, unless it would not be cost-effective (including consideration of energy
     savings) or is not reasonably available.
•    EISA 2007 sets federal mandatory efficiency standards for lighting and residential and
     commercial appliance equipment, including dishwashers, dehumidifiers, residential boilers,
     electric  motors, incandescent lamps, external power supplies, walk-in coolers and freezers,
     residential refrigerators and clothes washers.
•    EO 13423 states that at least 95 percent of all purchased electronic products must meet
     EPEAT standards; facilitates ENERGY STAR features on 100 percent of computers and
     monitors; and requires that 100 percent of electronic products must be  reused, donated,
     sold, or recycled using environmentally sound management practices.
•    EO 13514 sets the goal that 95 percent of new federal agency contract  actions including
     task and delivery orders, for products and services with the exception of acquisition of
     weapon systems, will be ENERGY STAR, FEMP, and/or EPEAT certified.
•    EO 13221 requires that a federal agency, each time "it purchases commercially available,
     off-the-shelf products that use external standby power devices, or that contain an internal
     standby power function, shall purchase products that use no more than one watt in their
     standby power consuming mode."  If unavailable, products with the lowest standby power
     wattage while in their standby power consuming mode shall  be purchased.

If a product to be purchased is not covered by an ENERGY STAR or FEMP rating, agencies
could seek to purchase products in the top 25% of efficiency for their class to maximize energy
efficiency.  Military installations should be in compliance with the Federal ENERGY STAR
Buildings Program Partnership MOU (http://www.wbdg.org/ccb/DOD/UDG/fedstar.pdf).

5.2 Facility Siting

5.2.a Summary

Separating land uses, spreading development out, and providing little or no public transportation
or safe walking and biking routes foster greater reliance on motor vehicles. As development
grows more dispersed, employees and residents must drive further to reach their destinations,
leading to more and longer vehicle trips and greater energy expenditures. Smart Growth is an
effort to create development that minimizes air and water pollution, encourage brownfields
clean-up and reuse, and preserve natural lands. The EPA Smart Growth Network developed a
set often basic principles to describe smart growth:
•    Create a range of housing opportunities and choices.
•    Create walkable neighborhoods.
•    Foster distinctive, attractive communities with a strong sense of place.
•    Preserve open space, farmland, natural beauty, and critical environmental areas.
•    Strengthen and direct development towards existing communities.
•    Provide a variety of transportation choices.
•    Make development decisions predictable, fair, and cost effective.

     2009).

Brownfields are real property, the expansion, redevelopment, or reuse of which may be
complicated by the presence or potential presence of a hazardous substance, pollutant, or
contaminant. Cleaning up and reinvesting in these properties takes development pressures off of
undeveloped, open land, and both improves and protects the environment. EPA provides
information on brownfield redevelopment at: http://www.epa.gov/brownfields/index.html.

Transit oriented development, closely related to smart growth, is creation of compact, walkable
communities centered around high quality train systems, and collector support transit systems
including trolleys, streetcars, light rail, and buses. Pedestrian/bicycle access and the use of mass
transportation have multiplier impacts on energy efficiency. Pedestrian/mass transit trips not
only conserve energy by reducing automobile use, but also reduce the heat island effect. The
heat island effect occurs when an area (i.e., city or industrial site) has consistently higher
temperatures than surrounding areas because of a greater retention of heat by buildings, concrete,
and asphalt. The heat island effect is worsened by additional paving for highway capacity
expansion, local  facility access streets and large parking lots. The greater the heat island effect,
the more energy must be expended on cooling.  In addition, increasing automobile capacity
through highway expansion or new alignment is itself a significant energy expenditure. EPA's
Smart Growth website provides information on transit oriented development:

nationally accepted benchmark for the design, construction and operation of high performance
green buildings (see Section 5.4 for more information on LEED®).  The LEED  for
Neighborhood Development Rating System integrates the principles of smart growth, urbanism
and green building into the first national system for neighborhood design. LEED® certification
provides independent, third-party verification that a development's location and design meet
accepted high levels of environmentally responsible, sustainable development. LEED® for
Neighborhood Development is a collaboration among USGBC, the Congress for the New
Urbanism and the Natural Resources Defense Council.  The pilot program began in the summer
of 2007.

In order to reduce the impacts of urban sprawl, or unplanned, uncontrolled spreading of urban
development into areas outside of the metropolitan region, and create more livable communities,
LEED® for Neighborhood Development communities are:

•    Locations that are closer to existing town and city center;
•    Areas with good transit access;
•    Infill sites;
•    Previously developed sites; and/or
•    Sites adjacent to existing development (USGBC 2009)

The LEED  Green Building Rating System for New Construction and Major Renovations
(http://www.usgbc.org/ShowFile.aspx?DocumentID=1095) provides guidance on site selection,
brownfield redevelopment, community connectivity and transportation access. The rating
system covers six major topics:

•    Sustainable Sites
•    Water Efficiency
•    Energy and Atmosphere
•    Materials and Resources
•    Indoor Environmental Quality
•    Innovation and Design Process

Credits are received in each of the various areas.  For example, sites would receive a credit as
sustainable in the area of development density for constructing or renovating a building on a
previously developed site and in a community with a minimum density of 60,000 square feet per
acre net.  Net density is calculated by dividing the total number of dwelling units existing in a
community by the net area in acres.

In evaluating potential facility sites, distance to transmission lines and/or other energy sources
should be considered.  It may be possible to construct renewable energy projects at certain
facility sites that have existing transmission capacity nearby, particularly brownfields, abandoned
mines, federal  Superfund sites, non-Federal Superfund sites, or other disturbed areas where
previous energy use occurred and infrastructure may already exist.  The EPA initiative, RE-
Powering America's Lands - Siting Renewable Energy on Current and Formerly Contaminated
Land and Mine Sites, contains a database of disturbed sites
(http://epa.gov/renewableenergyland/index.htm),  including the renewable energy potential of

these sites. In addition, EPA's Renewable Energy Interactive Mapping Tool
(http://epa.gov/renewableenergyland/mapping tool. htm) makes it possible to view EPA's
information about siting renewable energy on contaminated land and mining sites, alongside
other information contained in Google Earth. It enables the user to search by renewable energy
type or by contaminated land type. In addition to the site's location, it also provides:  site name
and identification information; EPA Region and program managing the site; a link to the site's
cleanup status information; and specific acreage and renewable energy resource information.

After the site is selected, the form and orientation of the building should be considered for
natural energy efficient design. Climatic factors, including solar radiation and wind, impact the
optimal location of the facility on the site. Specific needs will vary depending on the region of
the U.S., but the basic concerns are to maximize shading and ventilation during the cooling
season and to maximize solar radiation and minimize wind exposure during the heating season.
The building orientation can be adjusted according the position of the sun or prevailing winds,
while the building form can be designed to incorporate overhangs or other horizontal or vertical
shading elements (LDNR 2009).

See Section 5.4 Buildings.

5.2.c Review Considerations

309 Reviewers should identify whether  energy efficiency requirements are addressed in EISs. It
is understood that rather than repeating a lengthy discussion on these requirements, the EISs will
most likely incorporate them by reference by citing the appropriate document. Many times these
documents are made available via a link to a web site in the EIS. In most cases, this should
suffice.

Reviewers may recommend that potential facility sites be evaluated on according to smart
growth principles, such as whether a site contains a mix of land uses, a walkable neighborhood,
fosters a sense of place, and preserves open space by directing development toward existing
communities. The site selection process should encourage community and  stakeholder
collaboration in development decisions.

Reviewers may want to become familiar with the LEED for Neighborhood Development Rating
System  and the LEED  for New Construction and Major Renovations Rating System, during
their review of a federal facility's site selection. Both rating systems provide checklists of
criteria that include energy efficiency concerns. Reviewers  may want to recommend that a
facility achieve LEED® certification (see Section 5.4, Buildings).

Reviewers should consider whether the  alternatives analysis has included the consideration of
brownfield and/or infill development sites, where feasible and practicable.  In addition to other
environmental benefits, both brownfield and infill development may  be in closer proximity to
existing transportation infrastructure than undeveloped land, and will therefore reduce
transportation energy use when the site becomes operational. The adaptive reuse of existing

structures (e.g., historic school buildings) should be considered to reduce the energy used to
create and transport new building materials, and demolish/dispose of old structures.  309
Reviewer suggestions related to historic properties should be consistent with the requirements of
the National Historic Preservation Act (NHPA), Section 106.

When evaluating potential facility sites, reviewers should consider whether the alternatives
analysis has included the consideration of sites with existing transmission capacity nearby,
including disturbed sites where previous energy use occurred and infrastructure may already
exist.

For each site considered, the alternatives analysis should discuss the availability of and distance
to public transportation for employees.  Full consideration should be given to sites with bus, rail
and pedestrian routes within a 1/2 mile radius.  Sites that have pedestrian/bicycle access will
conserve energy, e.g., school buildings located within the community will reduce the need for
buses. For industrial facilities, the distance to waste  disposal should be considered.

The alternatives should include a discussion of how the facility orientation on the  site, from a
geothermal, wind, solar heat and shading perspective, will maximize and minimize heat gain,
according to seasonal and regional needs.

5.3 Construction

5.3.a Summary

Green construction seeks to minimize the impacts of construction activities on the environment.
This is achieved through using the principles of sustainable design and materials selection,
recycling and reuse, and energy efficiency (EPA 2009). The EPA report, Potential for Reducing
Greenhouse Gas Emissions in the Construction Sector, describes opportunities for incorporating
green construction principles, and improving energy efficiency in construction (EPA 2009b).
Opportunities for improving energy efficiency include:

•    Fuel efficiency/Equipment idling
•    Electricity use
•    Equipment maintenance
•    Equipment selection
•    Materials recycling

To achieve improvements in fuel efficiency, contractors can make changes ranging from
reducing equipment idling time and improving maintenance to replacing or repowering
equipment. Unnecessary idling occurs when trucks wait for extended periods of time to load or
unload, or when equipment that is not being used is left on, such as to maintain heating or
cooling for driver comfort.  Reduced idling reduces fuel consumption. Regulations restricting
idling were in place in almost half the states as of July 2008.  These regulations vary by state,
county, or city, but typically restrict idling to 3-10 minutes and do not distinguish between
gasoline or diesel vehicles.  Most of these regulations are relatively new and many have
associated information campaigns to increase awareness (EPA 2009b).

Two examples of maintenance activities that can improve energy efficiency are:

•    Forklift maintenance:  A recent study of forklift maintenance estimated that 50% of forklifts
     were not properly maintained, each of which could be wasting more than 400 gallons of
     propane annually.

•    Improperly inflated tires and poor wheel alignment, which can adversely affect fuel
     efficiency of small trucks by  3-4%. Under-inflated tires increase the tires' rolling
     resistance, and increased rolling resistance requires more fuel to move the vehicle (EPA
     2009b).

Identifying the proper equipment for a task can also provide fuel savings.  Truck engines too
large for an application burn more fuel by adding unnecessary weight. Longer term fuel saving
solutions involve replacing older, less fuel efficient equipment with newer models. Through
advances in engine technology, reduced equipment weight, and even some hybrid  technologies,
equipment manufacturers are offering more fuel efficient new equipment (EPA 2009b).

Reducing delivery vehicle trips to the construction site also results in lower fuel consumption.
For large projects, creating a consolidated location for materials  delivery may reduce  energy use.


                                          5-18                EPA Publication No. 315-R-09-001

                                         Energy Efficiency Reference for Environmental Reviewers
Switching transportation methods may also reduce fuel consumption.  EPA's Freight Logistics
and Energy Tracking (FLEET) Performance Model can help quantify the fuel use of various
shipment methods. Buying locally produced lumber and other materials can reduce fuel use in
transporting materials (EPA 2009b).

To improve energy efficiency, construction plans should include preserving existing vegetative
growth and replanting trees that must be removed with native species. This will reduce the heat
island effect (see Section 5.4, Buildings).

Wastes from new construction, renovation, and demolition projects generate about 25% of the
total U.S. solid waste volume (EPA 2009b). Debris can contain asphalt, concrete, wood, dry
wall gypsum, shingles, plastics, glass, and other materials. Data on reuse rates are very uncertain.
Rough estimates are that only about 15% of building construction and demolition debris (C&D)
is recycled, whereas up to 80% of roadway C&D (asphalt and concrete primarily) is
recycled/reused. However, states vary widely in terms of roadway C&D reuse rates. When
materials are reused or recycled, energy use is avoided. In  addition, virgin resources are
conserved and virgin mining impacts are  avoided.

Debris can be difficult to segregate into reusable components. Processing is often necessary, but
less often with roadway debris. Recycled asphalt pavement (RAP) is usually derived from the
demolition of degraded roadways and parking lots. This material can often be processed and
reused in new pavement. Both original asphalt binder and aggregate can be recycled. When just
the top pavement course layer of asphalt is removed for reclamation it is called "mining." When
both the pavement and base courses are reclaimed and reused in place, it is referred to as "full
depth reclamation." Construction materials such as cardboard, metal, glass gypsum board and
acoustical ceiling tile can be easily recycled. Some opportunities for materials recycling or reuse
in construction supplies are cited in Table 5-4.

Construction projects should not only recycle materials, but make use of recycled materials as
well.  Post-consumer material is defined as waste material generated by households or by
commercial, industrial and institutional facilities in their role as end-users of the product, which
can no longer be used for its intended purpose.

Pre-consumer material is defined as material diverted from the waste stream during the
manufacturing process (USGBC 2009). Examples of materials with high pre-consumer and
post-consumer content include: structural steel and decking, aluminum roof and wall panels,
acoustical ceiling tile, certain carpeting goods, gypsum board and some ceramic tiles.

Scrap tires are another material that can be reused in construction projects. 300 million scrap
tires are disposed in the U.S. every year. Reuse saves the embodied energy and impacts of tires
and reduces the need for petroleum. It also saves dramatically on landfill space. Scrap tires can
be reprocessed into chips or granules (crumbs), which can be used as:

•  Rubberized Chip Seal - A thin top-coat sealant composed of binder and a relatively fine
   aggregate to rehabilitate a worn asphalt road.
•  Rubberized Asphalt Concrete - A new asphalt layer on top of a worn pavement surface
   placed to rehabilitate a worn road.
•  Rubberized Asphalt Concrete - New asphalt road construction.
•  "Open-Graded" Rubberized Asphalt - A different type of asphalt similar to pervious concrete
   that promotes stormwater drainage to the side of the roadway and provides non-skid
   properties.
•  Tire Derived Aggregrate - Structural  fill in embankments, behind retaining and sound walls,
   in trenches; soil stabilization, including roadway collapse repair; and as vibration abatement
   along train tracks or near roadways.

Benefits of recycled tire materials can include increased strength, quieter roadway surfaces,
vibration control, and increased water penetration control.

EPA offers several software tools that provide information on the recycled content of common
construction materials:

     EPA Recycled Content Tool (ReCon):
     http://www.epa.gov/climatechange/wycd/waste/calculators/ReCon home.html.
•    EPA Waste Reduction Model  (WaRM):
     http://epa.gov/climatechange/wycd/waste/calculators/Warm home.html.
•    National Institute for Standards and Technology (NIST) Building for Environmental and
     Economic Sustainability (BEES): http://www.bfrl.nist.gov/oae/software/bees/.

While these tools were designed to compare greenhouse gas impacts and overall environmental
performance,  they are useful for determining energy efficiency as well. They attempt to provide
full life-cycle estimates of the  material (acquisition, manufacture, transportation, installation,
use, and waste management).

The LEED® Green Building Rating System for New Construction and Major Renovations
(http://www.usgbc.org/ShowFile.aspx?DocumentID=1095) contains energy efficiency related
criteria for new construction (see Section 5.4 for more information on LEED ). To score one
point under the LEED® system, projects must meet the following requirements.  Additional
points are awarded for exceeding these requirements:

•    Recycle and/or salvage at least 50% of non-hazardous construction and demolition debris.
     Develop and implement a construction waste management plan that, at a minimum,
     identifies the materials to be diverted from disposal and whether the materials will be
     sorted on-site or co-mingled. Excavated soil and land-clearing debris do not contribute to
     this credit.

•    Use salvaged, refurbished or reused materials such that the sum of these materials
     constitutes at least 5%, based on cost, of the total value of materials on the project.

•    Use materials with recycled content such that the sum of post-consumer recycled content
     plus one-half of the pre-consumer content constitutes at least 10% (based on cost) of the
     total value of the materials in the project.  Recycled content shall be defined in accordance
     with ISO 14021—Environmental labels and declarations—Self-declared environmental
     claims (Type II environmental labeling). Reutilization of materials such as rework, regrind
     or scrap generated in a process and capable of being reclaimed within the same process that
     generated it is excluded.

•    Use building materials or products that have been extracted, harvested or recovered, as well
     as manufactured, within 500 miles of the project site for a minimum of 10% (based on cost)
     of the total materials value. If only a fraction of a product or material is
     extracted/harvested/recovered and manufactured locally, then only that percentage (by
     weight) shall contribute to the regional value.

•    Use rapidly renewable building materials and products (made from plants that are typically
     harvested within a ten-year cycle or shorter) for 2.5% of the total value of all building
     materials and products used in the project, based on cost (USGBC 2009).

5.3.b Related Federal Partnership Programs

Clean Construction USA

Clean Construction USA, part of the National Clean Diesel Campaign (NCDC), is an EPA
program designed to promote the reduction of diesel emissions from construction equipment and
vehicles. Many of the strategies for emissions reduction also improve energy efficiency.
Information can be found at: http://www.epa.gov/otaq/diesel/construction/index.htm.

See Section 5.4, Buildings, for additional construction-related programs.

5.3.c Review Considerations

309 Reviewers should identify whether energy efficiency requirements are addressed in EISs. It
is understood that rather than repeating a lengthy discussion on these requirements, the EISs will
most likely incorporate them by reference by citing the appropriate document. Many times these
documents are made available via a link to a web site in the EIS.  In most cases, this should
suffice.

To minimize/mitigate the energy impact of construction activities, Reviewers should encourage
federal agencies to adhere to energy efficient practices described above, including: 1) reducing
idling by training drivers to turn off equipment and providing fuel-efficient auxiliary power for
the heat or air conditioning; 2) using fuel efficient and size appropriate equipment that is
properly maintained; and 3) minimizing delivery vehicle trips.

Reviewers may want to recommend that projects be certified using LEED  for New
Construction and Major Renovations.  Regardless of whether projects are LEED® certified,
construction plans should document waste reduction efforts, including using recycling
construction materials with significant post-consumer content, salvaged, refurbished or reused
materials, rapidly renewable materials, and locally produced or on-site materials (e.g., lumber)
when feasible. Reviewers may want to recommend using one of the recycled content software
tools described above for material selection.

5.4 Buildings

5.4.a Summary

In the United States, the best performing buildings use 75 percent less energy than the worst
performing buildings. This difference cannot be accounted for by particular technologies,
climate, building size, or building age (EPA 2003). The opportunity exists to significantly
improve building energy efficiency by retrofitting existing buildings, and incorporating energy
efficient design into new construction.

The Federal government owns approximately 445,000 buildings with total floor space of over
3.0 billion square feet, in addition to leasing an additional 57,000 buildings comprising 374
million square feet of floor space (DOE 2006). These include a large variety of building types,
including offices, retail shops, hospitals, schools, housing, warehouse/storage, airports, highway
rest stops, visitor centers, border inspection facilities.

Federal Leadership in High Performance and Sustainable Buildings Memorandum of
Understanding

In January 2006, 19 federal agencies signed a Memorandum of Understanding (MOU) to commit
to federal leadership in the design, construction, and operation of high-performance and
sustainable buildings. The MOU directs agencies completing new construction to reduce the
energy cost budget by 30% compared to the baseline building performance rating per the
American Society of Heating, Refrigerating and Air-Conditioning Engineers, Inc., (ASHRAE)
and the Illuminating Engineering Society of North America (IESNA) Standard 90.1-2004,
Energy Standard for Buildings Except Low-Rise Residential. For major renovations, agencies
should reduce the energy cost budget by 20 percent below pre-renovations 2003 baseline. The
five guiding principles of the MOU address:

•    Employing integrated design;
•    Optimizing energy performance;
•    Protecting and conserving water;
•    Enhancing indoor environmental quality; and
•    Reducing the environmental impact of materials.

The MOU can be found at: http://www.energystar.gov/ia/business/Guiding Principles.pdf

EO 13423 made permanent the elements of the MOU, and as directed in the EO, the Interagency
Sustainability Working Group developed technical guidance in December 2008 to assist agencies
in meeting the EO goals and statutory requirements. The guidance (High Performance and
Sustainable Buildings Guidance} can be found at: http://www.wbdg.org/pdfs/hpsb_guidance.pdf
and frequently asked questions based on the comment resolution summary of the draft guidance
can be found  at: http://www.wbdg.org/pdfs/hpsb_guidance_comment_sum.pdf

The Buildings and Thermal  Systems Center at the National Renewable Energy Laboratory
provides another information source on high performance buildings.

Greening Federal Facilities: An Energy, Environmental, and Economic Resource Guide for
Federal Facility Managers and Designers (Second Edition)

DOE, in partnership with DoD, GSA, EPA and other federal agencies, authored a comprehensive
resource guide designed to increase energy and resource efficiency, cut waste, and improve the
performance of Federal buildings and facilities. The guide is intended primarily for Federal
facility managers, and is available at: http://www.nrel.gov/docs/fy01osti/29267.pdf.

Federal Building Codes and Standards

DOE works in partnership with the International Code Council (ICC), the American Society of
Heating, Refrigerating and Air-Conditioning Engineers, Inc. (ASHRAE), the Illuminating
Engineering Society of North America,  and other code user groups to develop stringent and
easy-to-understand building energy codes (see Building Energy Codes program, Section 5.4.b).

Federal building codes and standards apply to buildings constructed or used by any Federal
agency that is not legally  subject to state or local building codes.  Different federal codes exist
for low rise residential buildings built before and after January 3, 2007, and for commercial and
multi-family high rise buildings.

The current Federal code  for low-rise residential building energy efficiency for which design for
construction began on or  after January 3, 2007 can be obtained in the Code of Federal
Regulations in Title 10, Part 435, subpart A, sections 435.1 through 435.8
(http://www.gpoaccess.gov/cfr/retrieve.html).  The new rule requires that new Federal residential
low-rise (3 stories or less  above grade) buildings achieve an energy consumption level of at least
30% below those set by the 2004 International Energy Conservation Code (IECC), if cost
effective. The Federal agencies procuring new housing  are responsible for complying with this
code, including determining levels of energy efficiency that can be achieved cost effectively
(DOE 2009i).

The Federal code for energy efficiency in low-rise residential buildings for which design for
construction began before January 3, 2007 can be obtained at the same link as for the new rule
above but in sections 435.300 through 435.306 (Subpart C).  The requirements in the old Federal
residential code are determined on a project-specific basis using software called COSTS APR
(Conservation Optimization Standard for Savings in Federal Residences). Federal staff must run
COSTS APR to generate a project-specific point system that accounts for factors such as local
fuel costs, climate, and construction costs for energy efficiency measures. The point system is
completed by the building designer and  contains options for energy efficiency measures such as
insulation levels. The designer selects energy efficiency measures and obtains the points for
                                           5-26                EPA Publication No. 315-R-09-001

these selections. The more points, the more energy efficient the design. A sufficient number of
points must be obtained to achieve compliance with the code (DOE 2009i).

The current Federal code for energy efficiency in new commercial and multi-family high-rise
residential buildings (10 CFR Part 434), can be obtained at:
http://www.access.gpo.gov/nara/cfr/waisidx  05/1 Ocfr434  05.html. This code was issued on
January 1, 2002, and is based on ASHRAE/IES Standard 90.1-1989, and all addenda. It became
effective on October 8, 2001. Software to assist in complying with the envelope and lighting
portions of the Federal code can be downloaded at:
http://www.energycodes.gov/federal/exist fedcom.stm. Overall, the lighting requirements in the
new Federal code are more stringent than those in Standard 90.1-1989.

To implement the envelope requirements  for the new Federal commercial building code,
individual Alternate Component Package (ACP) tables
(http://www.energycodes.gov/federal/acp_tables.stm) have been developed for 234 different
locations around the United States and abroad. The tables are given in terms of both shading
coefficient (SCx) and solar heat gain coefficient (SHGC) and inch-pound (IP) and System
International (SI) units.

DOE also provides software through its Building Energy Code program to help  practitioners
ensure code compliance for residential and commercial buildings: http://www.energycodes.gov/.

Building Energy Efficiency Rating Systems

Leadership in Energy and Environmental Design (LEEDR)

The GSA supports the use of the USGBC LEED® Green Building Rating System, a third-party
certification program for the design, construction and operation of high performance green
buildings. Within LEED®, there are rating systems for:

•    New Construction
•    Existing Buildings: Operations and Maintenance
•    Commercial Interiors
•    Core and Shell
•    Laboratories
•    Schools
•    Retail
•    Healthcare
•    Homes
•    Neighborhood Development (pilot)

LEED  offers four levels  of certification: Certified, Silver, Gold and Platinum.  LEED  Version
2.2 was replaced with Version 3.0 in April 2009.  Version  3.0 improved on earlier versions by
aligning credit weighting and scoring between the different LEED  rating systems, and basing
scoring on a 100-point scale. With revised credit weightings, LEED® now awards more points
for strategies that will have greater positive impacts on energy efficiency and CO2 reductions.

                                         Energy Efficiency Reference for Environmental Reviewers
The new version also awards points to projects for addressing regional environmental issues
(e.g., in urban Florida, decreased reliance on fossil fuels, reuse of existing building stock,
decreased reliance on insufficient municipal wastewater plants, and utilization of abundant local
sunshine). These regional issues were identified through USGBC's regional councils, chapters
and affiliates (USGBC 2009).

Notably, some Federal agencies have established specific energy efficiency and building
performance goals (in LEED®) for applicable projects (see Table 5-5).

The EPA ENERGY STAR program also offers a certification for buildings. It functions as an
interactive energy management tool that can be used to track and assess energy and water
consumption (see Section 5.1, Appliances and Equipment).  While buildings can be dual certified
using both LEED® and ENERGY STAR, the LEED® system references ENERGY STAR
requirements within its rating criteria.

The Green Building Initiative's Green Globes program is another popular third party rating and
review system for sustainable design practice that contains energy efficiency related criteria. The
Green Globes rating system uses a 1000 point base total scoring system and has four levels of
certification with a 4 Globes rating being the highest level of certification.  The Green Globes
system, which originated in Great Britain, is not as widely used in the United States as LEED  .

Whole Building Design

The whole building design concept departs from the typical construction approach by forming
the entire building stakeholder community into a team at the beginning of a project. The team
examines project objectives, building materials, systems, and assemblies from various
perspectives, and improves the final building product by integrating the components into a more
energy efficient system.  Lessons learned are compiled in reports and reference documents to be
used by other members of the construction industry (Prowler and Vierra 2008).

The Whole Building Design Guide (WBDG) is a web-based portal providing government and
industry practitioners with information on building-related guidance, criteria and technology
from a 'whole buildings'  perspective. The WBDG web site is offered by the National Institute of
Building Sciences (NIBS) through funding support from the Department of Defense, Naval
Facilities Engineering Command (NAVFAC) Engineering Innovation and Criteria Office,
USAGE, U.S. Air Force, GSA, Department of Veterans Affairs, National Aeronautics and Space
Administration (NASA), and DOE, and the assistance of the Sustainable Buildings Industry
Council (SBIC).

The Whole Building Design Guide website (http://www.wbdg.org/design/buildingtypes.php)
provides extensive information on improving environmental performance for all building types.
Design guidance is available by building type or use,  including:

•    Ammunition & Explosive Magazines
•    Archives
•    Aviation
•    Community Services
•    Educational Facilities
•    Federal Courthouse
•    Health Care Facilities
•    Land Port of Entry

Design Guidelines for Specific Building Types

EnergySmart, part of the DOE Building Technologies Program (see Section 5.3) offers design
guidelines specifically to improve energy efficiency at schools (AdvancedEnergy Design Guide
for K-12 School Buildings,
http://wwwl.eere.energy.gov/buildings/energysmartschools/design.html) and hospitals
(Advanced Energy Design Guide for Hospitals,
http://wwwl.eere.energy.gov/buildings/energysmarthospitals/).  The ASHRAE-sponsored
Energy Design Guides provide information for improving energy at K-12 School Buildings,
Small Retail Buildings, Small Office Buildings, and Small Warehouses and Self-Storage
Buildings. The guides are available at: http://www.ashrae.org/publications/page/1604.

Building Commissioning

Building commissioning is a project management practice that formalizes review of all project
expectations for facilities and their systems during planning, design,  construction, and occupancy
phases. It is an umbrella process that seeks to improve energy efficiency and indoor air quality
by uncovering deficiencies in design or installation using peer review, inspection and functional
performance testing, and by delivering preventive maintenance plans, tailored operating
manuals, and training procedures. ASHRAE defines commissioning  as ".. .the process of
ensuring that systems are designed, installed, functionally tested, and capable of being operated
and maintained to perform in conformity with the design intent... Commissioning begins with
planning and includes design, construction, start-up, acceptance and training, and can be applied
throughout the life of the building (WBDG 2008)."

Building commissioning is commonly used for major building systems, including electrical
power and controls, HVAC, and building lighting and controls (and potentially for building
envelopes). Recent case studies conducted in private sector facilities have shown that the
building commissioning process can improve new building energy performance by 8% to 30%.

Currently, no building code requirements exist at a national level for building commissioning.
However, GSA, NAVFAC, and the USAGE have adopted formal requirements for
commissioning of their construction projects.  Fundamental building commissioning is also a
prerequisite for obtaining certification using LEED® or Green Globes rating systems.  LEED®
and Green Globes require a comprehensive fundamental commissioning plan to cover the major
building energy systems that must be developed by someone outside the design team prior to
construction.  A follow-up report must be filed after construction and prior to building  occupancy
noting corrective  measures required. Many new facilities, such as clean rooms and data rooms
with unique design challenges, are utilizing the commissioning process to achieve higher energy
efficiency and indoor air quality (WBDG 2008).

The Whole Building Design guide recommends that projects employing the building
commissioning process follow the procedure outlined in ASFIRAE Guideline 0 - 2005
                                           5-30                EPA Publication No. 315-R-09-001

commission any building system. DOE also provides a resource guide, Continuous
Commissioning Guidebook for Federal Energy Managers (2002), available at:

Life cycle costing

When selecting materials and components for buildings, designers can employ life cycle costing
to maximize energy efficiency. The National Institute for Standards and Technology (NIST)
Building for Environmental and Economic Sustainability (BEES) model
(http://www.bfrl.nist.gov/oae/software/bees/) uses the life-cycle assessment approach specified
in the ISO 14040 series of standards to measure the environmental performance of building
products. All stages in the life of a product are analyzed: raw material acquisition, manufacture,
transportation, installation, use, and recycling and waste management. Environmental and
economic performance are combined into an overall performance measure.  BEES has been
supported in part by the U.S. EPA Environmentally Preferable Purchasing (EPP) Program. The
EPP program is charged with carrying out EO 13423 (See Chapter 3).

Building Envelope

The building envelope consists of all exterior components of a building. The building envelope
concept seeks to improve the energy efficiency and thermal performance  of materials for
windows, doors, walls, roof and foundation materials, including how they work together as a
system. To improve energy efficiency,  building designers/managers can control heat loss and
solar gain through windows and doors, provide better insulation and air barrier design. Air
barriers are systems of materials used to control airflow in building enclosures. They typically
completely enclose the air within a building. The physical properties which distinguish air
barriers from other materials are the ability to resist air flow and air pressure (Lstiburek 2004).
The National Institute for Standards and Technology provides recommendations to maximize the
energy efficiency of air barriers (http://www.nist.gov/index.html).

The International Energy Conservation Code (IECC) and ASHRAE 90.1  provide guidance on
energy efficient insulation levels, and door and window R values. Both of these codes govern
minimum building envelope standards for commercial buildings.  The  IECC also covers window
glazing sizes, configuration, and using  glass with the proper attributes for optimum solar heat
gain coefficients (SHGC) suitable for the climate region. Building siting  and window
placements can be tested and optimized by utilizing computerized energy modeling programs
that input building orientation, building envelope thermal insulation values, heating and cooling
energy loads, lighting and power loads for three or more seasons.

Indoor Air Quality

One potential risk associated with implementation of green building standards and energy
efficiency measures is unintended indoor air quality impacts. For  example, if buildings are sealed
tightly, ventilation rates are reduced and re-circulated air is used,  indoor pollutants coming from
                                          5-31                EPA Publication No. 315-R-09-001

                                          Energy Efficiency Reference for Environmental Reviewers
building materials, furnishings, and occupant activities may be retained. Reduced drying of
buildings can also result, which promotes moisture accumulation and mold growth problems.
Green building and energy conservation strategies can avoid these problems through proper
design. EPA's Indoor airPLUS is a comprehensive program that promotes professional best
practices for minimizing IAQ problems (http://www.epa.gov/indoorairplus/). Specific indoor air
quality measures for energy efficiency programs can include: a) radon testing and mitigation; b)
whole-building and local exhaust ventilation systems per ASHRAE Standard 62.2; c)
mold/moisture control measures; d) combustion safety and house pressure diagnostics; and e)
integrated pest management.

Lighting

Energy consumption for all lighting in the United States is estimated to be about 22%  of the total
electricity generated  in the country. More than half of the  energy is consumed in the commercial
sector, where lighting coincides with peak electrical demand and contributes to a building's
internal heat generation, increasing air-conditioning load.
The conversion of electricity into useful light is one of the least efficient energy conversion
processes in buildings today. Lighting accounts for 35-45% of an office building's energy use,
and is a significant energy user in all  types of buildings. Advanced lighting technologies can
significantly improve the energy efficiency of lighting and reduce building energy consumption
and costs (DOE 2009k).

High  efficiency lighting alternatives exist for new construction and for retrofitting existing
lighting systems. The California Energy Commission offers the following recommendations for
increasing the energy efficiency of lighting systems:

•     Advanced fluorescent lighting:  In most interior spaces, facilities can replace or upgrade
      existing fixtures to include high-efficiency fluorescent lamps, electronic ballasts, custom
      designed reflectors, and appropriate lenses or louvers.

•     High-intensity discharge lighting: In outdoor applications and in warehouses and indoor
      areas with ceilings over 15 feet, facilities can replace highly inefficient incandescent or
      mercury vapor lamps with metal halide and high-pressure sodium lamps. High-intensity
      discharge lamps generate high lighting output, use a fraction  of the energy required for
      incandescent or mercury vapor  equivalents, and have substantially longer lamp life than
      incandescents.

•     Lighting controls: Simple controls can eliminate unnecessary lighting in the many facility
      areas that do not require continuous lighting. Occupancy sensors detect the presence  of
      personnel within an area and turn lights on and off accordingly. Time switches that turn
      lighting systems on and off are  useful for outdoor signs, security lighting, and corridors.
      Dimming systems take advantage of daylight to further reduce  energy use and costs.
      Photocell controls provide easy, effective on/off switching of outdoor lighting. In addition,
      photocells can be combined with time switch controls for areas that don't require lighting
      all night.
                                           5-32                EPA Publication No. 315-R-09-001

                                          Energy Efficiency Reference for Environmental Reviewers
•    Maintenance: A program of regular cleaning, replacement, and maintenance of lamps and
     luminaries can significantly save energy. A typical lamp, as it reaches 80% of its useful
     life, produces 15-35% less light due to lamp degradation. Dust, dirt, and other materials on
     lamps, reflectors, and lenses can decrease lighting output by 30% or more. Photocells used
     to activate outdoor lights should also be cleaned regularly (CEC 2009).

The DOE Lighting Development and Research program provides information on high efficiency
lighting. Mandatory federal building codes require high efficiency lighting and lighting controls
in new construction. In addition, LEED® criteria include designing buildings with occupant
controls for lighting, (e.g., task lighting).

To maximize daylight in the building interior, building designers can select office systems
furniture with 54 inch panels or less that will allow natural daylight from the exterior walls to
permeate into the building core and reduce artificial light during daylight hours. Designing light
shelves and light colored or reflective surfaces near the building perimeter will also bounce the
light further into the building space. The WBDG contains specifications for office systems
furniture (including recycled material content):
http://www.wbdg.org/design/greenspec msl.php?s=125900.

Heating, Ventilation, and Air Conditioning (HVAC)

Underfloor HVAC Systems Traditional air conditioning uses overhead variable air volume
(VAV), which supplies air through metal ductwork to boxes in the ceiling.  The VAV boxes
respond to  space thermostats to provide cooling. Air is generally returned to the mechanical
room through the space above the ceiling. This traditional system has two inefficiencies.  First,
because the air  supply and return are located in the ceiling, some amount of air short cycles, or
returns without having  done any cooling work in the room.  Second is the high cost for
renovations after the building is occupied. With the cooling system located in the ceiling and
constructed from sheet metal, renovations routinely require the energy intensive removal of
ceiling systems and installation of new ductwork (Spinazzola 2005).

Underfloor HVAC systems supply air through floor air devices that are either manually adjusted
or controlled automatically by thermostats. Air is generally returned through the ceiling.
Underfloor HVAC is more efficient (no short cycling  of air), provides more effective ventilation
by introducing supply at the floor and returning it at the ceiling, and results in easier and less
energy intensive renovations (Spinazzola 2005).

Integrated Energy Systems (IES) Integrated systems bring together gas-fired and electrically
driven equipment to provide heating, cooling, dehumidification, and electrical service to
commercial and public buildings. The three principal configurations are (1) hybrid chiller plants
incorporating gas-fired and electrically driven chillers, (2) desiccant dehumidifiers using waste
heat from combustion of natural gas to regenerate the  desiccant,  and (3) combined heating,
cooling, and power systems (cogeneration) that include on-site electrical power generation with
heating and cooling space conditioning and/or potable hot water production. System energy
efficiency is increased significantly in these applications when waste heat from one component
of the integrated system is used by a second component (e.g., waste heat from power generation

used to provide hot water for laundry facilities or for space heating, heat from engine-driven
chiller used to regenerate desiccant in desiccant dehumidifier) (ORNL 2000).

Combined heat and power (CHP), also known as cogeneration, is the simultaneous production of
electricity and heat from a single fuel source, such as natural gas, biomass, biogas, coal, waste
heat, or oil.  CHP is an IBS that can be modified depending upon the needs of the energy end
user. CHP requires less fuel to produce a given energy output, and avoids transmission and
distribution losses that occur when electricity travels over power lines. CHP can greatly increase
the facility's operational efficiency and decrease energy costs (EPA 2009a). On average, CHP
facilities improve energy efficiency by up to 80% when compared to both heat and electricity
generation. This dramatic energy savings potential significantly reduces carbon dioxide
emissions as well as decreases operating costs and improves economic viability (See Chapter 4
for additional information on EPA's CHP Partnership).

Thermally activated technologies (TAT) are another IES which would typically be designed for
smaller office buildings where packaged rather than custom designed units are better utilized.
These technologies vary depending on the system used and are still being tested for commercial
use (TAT: Integrated Energy Systems Brief.,
http://www.eere.energy.gov/de/pdfs/thermally_activated_ies_tech_brief.pdf). Current TAT
designs may supplement up to 40% of power needs for a particular facility under optimum
conditions.

Researchers at Oak Ridge National Laboratory (ORNL) evaluated various IES technologies, as
well  as efficiency concepts, based on actual performance testing from the ORNL IES Laboratory
in a research paper: Evaluation of Difference Efficiency Concepts of an Integrated Energy
System., http://www.ornl.gov/~webworks/cppr/y2001 /pres/121706.pdf. The paper concludes that
standard guidelines for efficiency calculations are needed for IES manufacturers and end users.
At a  minimum,  manufacturers and users should indicate and/or be aware of the basis for
efficiency calculations.

Other technologies that are less power dependent and re-emerging due to their energy efficiency
include absorption chillers and desiccant humidifiers. Absorption chillers provide cooling by
using a heat source (instead of mechanical energy) and converting the source into cooling.
Detailed information on absorption chillers can be found at:
http://www.newbuildings.org/downloads/guidelines/AbsorptionChillerGuideline.pdf

Desiccant dehumidifiers rely on absorption media to provide evaporative cooling and
dehumidification. Both absorption chillers and desiccant humidifiers are used occasionally when
indoor air quality issues are a major concern and both use less power than their conventional
counterparts.

Passive Cooling.

The term "heat island" describes built up areas that are hotter than nearby rural areas. The annual
mean air temperature of a city with 1 million people or more can be 1.8-5.4°F (1-3°C) warmer
than its surroundings. In the evening, the difference can be as high as 22°F (12°C). Heat islands
can affect communities by increasing summertime peak energy demand, air conditioning costs,
air pollution and greenhouse gas emissions, heat-related illness and mortality, and water quality
(EPA 2009b). More information is available at: http://www.epa.gov/heatisland.

The heat island effect can be reduced using four main strategies:  1) increasing tree and
vegetative cover, 2) using cool pavements, 3) installing green roofs (also called "rooftop
gardens" or "eco-roofs"), and 4) installing cool—mainly reflective—roofs.

Using shading devices or tall native trees around the parking and other paved areas, as well as
using paving materials with a higher Solar Reflectance Index (SRI) (typically with an SRI at 30
and above) will reduce the heat island effect and subsequent need for additional energy use to
cool the facility.  Open grid paving is another technique that allows grass or plants to help reduce
the heat island effect. More information on cool pavements can be found at:
http://www.epa.gov/heatisland/mitigation/pavements.htm.

A green roof, or rooftop garden, is a vegetative layer grown on a rooftop. Green roofs provide
shade and remove heat from the air through evapotranspiration, reducing temperatures of the
roof surface and the surrounding air. On hot summer days, the surface temperature of a green
roof can be cooler than the air temperature, whereas the surface of a conventional rooftop can be
up to 90°F (50°C) warmer.

Green roofs can be installed on a wide range  of buildings, from industrial facilities to private
residences. They can be  as simple as a 2-inch covering of hardy groundcover or as complex as a
fully accessible park complete  with trees (EPA  2009). More information can be found at:
http: //www. epa.gov/heati si and/miti gati on/greenroofs. htm.

Energy-efficient cool roofing systems can reduce roof temperatures significantly during the
summer, and thus reduce the energy requirements for air conditioning. A Cool Roofing Materials
Database was compiled by the  Berkeley Laboratory's Heat Island Project to assist with the
selection of roofing materials which reflect, or otherwise  reject, the sun's radiant energy, before it
penetrates into the interior of the building.  More information can be found at:
http://eetd.lbl.gov/CoolRoof/ and http://www.epa.gov/heatisland/mitigation/coolroofs.htm.

Stormwater management

EISA 2007, Title IV, Subtitle C, Sec. 438,  states, "The sponsor of any development or
redevelopment project involving a federal facility with a footprint that exceeds 5,000 square feet
shall use site planning, design,  construction, and maintenance strategies for the property to
maintain or restore, to the maximum extent technically feasible, the predevelopment hydrology
of the property with regard to the temperature, rate,  volume,  and  duration of flow."  This
                                           5-35                 EPA Publication No. 315-R-09-001

                                         Energy Efficiency Reference for Environmental Reviewers
provision requires federal sites to achieve/maintain the predevelopment hydrology to the
"maximum extent technically feasible."

To reduce the amount of energy required to construct and maintain stormwater management
infrastructure, projects can manage water onsite by the use of site developed wetlands and
"bioswales," vegetated buffers that slow water runoff and encourage infiltration. To comply
with EISA 2007, projects larger than 5,000 square feet must retain a site's natural hydrology, but
smaller projects can improve efficiency by adopting this goal as well. Porous paving and
permeable pavements can also be used for paving where light traffic and automotive vehicles are
the main use vehicles. Infiltration can be encouraged on the building itself through the
construction of green roofs, vegetated planters and tree boxes.  These and other approaches to
infiltrate, evapotranspire, capture and reuse stormwater to maintain or restore natural hydrologies
are collectively known as green  infrastructure. Specific site practices can be found at:
http://cfpub.epa.gov/npdes/home.cfm?program id=298 and in the EPA publication: Using Smart
Growth Techniques as Stormwater Best Management Practices
(http://www.epa.gov/smartgrowth/pdf/sg stormwater  BMP.pdf).

Water Efficiency

EO 13514 sets goals for federal  agencies to improve water use efficiency and management by:
   •   reducing potable water consumption intensity by 2 percent annually through fiscal year
       2020, or 26 percent by the end of fiscal year 2020, relative to a baseline of the agency's
       water consumption in fiscal year 2007, by implementing water management strategies
       including water-efficient and low-flow fixtures and efficient cooling towers;
   •   reducing agency industrial, landscaping, and agricultural water consumption by 2  percent
       annually or 20 percent by the end of fiscal year 2020 relative to a baseline of the agency's
       industrial, landscaping, and agricultural water consumption in fiscal year 2010;
   •   consistent with State law, identifying, promoting, and implementing water reuse
       strategies that reduce potable water consumption; and
   •   implementing and achieving the objectives identified in the stormwater management
       guidance referenced in section 14 of this order.

A variety of water saving strategies exist for new construction and existing buildings.  A major
source of water savings for most building projects is the design of water efficient landscaping.
Xeriscaping is landscaping where supplemental irrigation is not required. It includes the
reduction of lawn grass and planting of hardy native plant species.

Pressure management, or reducing excessive pressures in the distribution system, can save a
significant quantity of water. Reducing water pressure can decrease leakage, amount of flow
through open faucets,  and stresses on pipes and joints which may result in leaks. Lower water
pressure may also decrease system deterioration, reducing the need for repairs and extending the
life of existing facilities. Furthermore, lower pressures can help reduce wear on end-use fixtures
and appliances. More information can be found in the EPA Water Conservation Plan
Guidelines, Appendix A: http://www.epa.gov/watersense/docs/app a508.pdf.

Water recycling is reusing treated wastewater for beneficial purposes such as agricultural and
landscape irrigation, industrial processes, toilet flushing, and replenishing a ground water basin
(referred to as ground water recharge).  Examples of water recycling opportunities include:

    •   Harvesting rainwater from the building roof (in appropriate climates) for use as graywater
       in flushing toilets or to provide on site watering for landscaping.
    •   Using washing machine graywater for landscape irrigation.
    •   Installing toilets that have handwashing basin above toilet tank so used water flushes
       toilet.

The EPA Region 9 website provides further detail on water recycling opportunities
(http://www.epa. gov/region09/water/recycling/) and the EPA Office of Water published the 2004
report, Guidelines on Water Reuse (www.epa. gov/ord/NRMRL/pubs/625r04108/625r04108.pdf)
(EPA 2004).

Other strategies to improve water efficiency include:
    •   Establish a monitoring system and maintenance program to replace leaking pipes as they
       deteriorate.
    •   Install hot water on demand heaters to reduce potable water waste while waiting  for hot
       water.
    •   Install solar hot water heaters.

WaterSense, a partnership program sponsored by EPA, identifies and labels high efficiency
water-related products for consumers (http://www.epa.gov/WaterSense). The installation of high
efficiency "Water Sense" labeled plumbing fixtures, including automatic or self-closing  faucets
reduces water use and wastewater volumes for all types of buildings. Examples of high
efficiency plumbing fixtures include: dual flush toilets, composting toilets, waterless or pint flush
urinals and gray water collected and filtered from sink and shower drains to flush toilets.
Currently there are multiple efficient plumbing fixtures available that have reduced volumes
below the 1.6 gal per flush mandated in the Energy Policy Act of 1995.

The WaterSense program also provides technical assistance for different groups of water
consumers, including:
    •   Guidelines and strategies for communities to implement water conservation plans
       (http://www.epa.gov/watersense/pubs/guide.htm).
    •   Water Use Audits that provide water systems and their customers with information about
       how water is used and how usage might be reduced through specific conservation
       strategies (http://www.epa.gov/watersense/docs/app_a508.pdf).
    •   Assistance to utilities  with new technologies for leak detection equipment and water loss
       control (http://www.epa.gov/WaterSense/docs/utilityconservation 508.pdf).
    •   Assistance to utilities  with designing rebate programs for customers to replace  older
       fixtures  (http://www.epa.gov/watersense/docs/app_a508.pdf).
    •   Assistance to utilities  with designing water standards and regulations that maximize
       conservation (http://www.epa.gov/watersense/docs/app_a508.pdf).

DOE's Office of Energy Efficiency and Renewable Energy sponsored research that resulted in a
technical report, Consumptive Water Use for U.S. Power Production
(http://www.nrel.gov/docs/fy04osti/33905.pdf). The 309 reviewer may use this report as a
reference to federal agencies for determining water efficiency in building cooling systems.  The
report focuses on water consumption at power plants to provide the data needed to make accurate
comparisons between water uses of building cooling systems. While it does not answer the
question of which system consumes more water, it does provide the metric for determining the
amount of water used at the power plant when the amount of energy consumed at the site is
known. If used, the reviewer should be clear that a thorough understanding of local conditions is
necessary to properly interpret the data in the report.

The 2009 GovEnergy presentation, "EPA - A Leader in Water Conservation," details EPA's
internal strategies for reducing water use at their own facilities
(http://www.govenergy.com/pdfs/presentations/Water-Session05/Water-Session05-
Johnson_Sieber.pdf) (Green et al. 2009). The presentation provides ideas that may be useful for
other federal facilities in reducing water consumption.
5.4.b Related Federal Partnership Programs

Building Technologies Program

The DOE Building Technologies program, supported by DOE national laboratories, was
established to improve the efficiency of buildings and the equipment, components, and systems
within them through partnerships with the private sector, state and local governments, and
universities (DOE 2009e). The Building Technologies Program's strategic goal is to create
technologies and design approaches that lead to marketable zero energy homes by 2020 and zero
energy commercial buildings by 2025. A net-zero energy building is a residential or commercial
building with greatly reduced energy needs due to efficiency gains of greater than 60% to 70%
compared to conventional practice, with the balance of energy needs supplied by renewable
technologies.

The Building Technologies Program has three main focuses: researching building designs,
materials and construction techniques; applying them to residential and commercial buildings;
and helping to develop ways to encourage implementation of these improvements.  The primary
research involves partnerships with industry to examine "whole building design" and "building


                                          5-38                EPA Publication No. 315-R-09-001

envelope" concepts. The building envelope concept is part of whole building design, and
involves focused research into materials and thermal performance for windows, doors, walls,
roof and foundation materials, including how they work together as a system. Research focuses
on controlling heat loss and solar gain through windows and doors, insulation materials research,
or moisture control technologies. This section of the Building Technologies program is also
developing test methodologies to measure material properties.  The program uses program
outreach, cooperative industry projects, and contributions to standards-setting organizations to
transfer technical information and expertise to the building materials industry, industry
associations, and federal/state agencies (DOE 2009d).

The Building Technologies Program applies these whole building and building envelope
concepts through two programs: "Building America" program for residential applications, and
the "High Performance Buildings" program (Commercial Buildings Integration) for commercial
applications (see following Energy Star section).

The Building Technologies Program website:
, provides information and resources on the
program.  The program operates a database: http://eere.buildinggreen.com/, which collects data
on various factors that affect a building's performance (e.g., energy, materials, and land use)
from buildings around the world, ranging from homes and commercial interiors to large
buildings, campuses and neighborhoods (DOE 2009f).

Several other websites and reference materials provide useful information regarding whole
building design.  The Whole Building Design Guide website: 
is a portal run by the National Institute of Building Sciences and provides government and
industry practitioners with current building-related guidance, criteria and technology from a
whole building design perspective.  The Whole-Building and Community Integration Group

Residential building construction techniques are refined in this program, and are then published
in a six-volume set of Best Practices Handbooks (DOE 2009b). The first five volumes are
divided by climate zones and the sixth volume focuses on solar thermal and photovoltaic systems
for all climates. Each volume contains information and instructions in separate sections written
for seven specific stakeholders: homeowners, managers, marketers, site planners and developers,
designers, site supervisors, and trades and crafts.

High Performance Commercial Buildings Program

The High Performance Commercial Buildings Program  directly applies whole building design
research for commercial buildings (DOE 2009J).  The program  consists of government and
industry research partnerships and information dissemination. Government/industry partnerships
include the Retailer Energy Alliance, Commercial Real Estate Energy Alliance, and the
Institutional Energy Alliance (DOE 2009g).  The technologies promoted within the program
have the potential to result in substantial energy savings as commercial buildings constitute 17%
of U.S. energy use.

The High Performance Buildings program disseminates information from its website, which
takes the form of energy simulation software:

Building Energy Codes

Building energy codes directly impact energy efficiency by setting the lowest acceptable
building practice.  To be effective, they are supported through education, implementation, and
enforcement. The Building Energy Codes program is an information resource on national model
energy codes. The program works with government agencies, state and local jurisdictions,
national code organizations, and industry to promote stronger building energy codes and help
states adopt, implement, and enforce those codes (DOE  2009c). The program also develops and
promulgates Federal energy codes for government residential and commercial buildings.

Lighting Research and Development Program

The Lighting Research and Development Program, which operates within the DOE Building
Technologies Program, conducts and collaborates on research on energy efficient lighting
technologies and practices. The program focuses mainly on two areas: spectrally enhanced
lighting (SEL) and solid-state lighting (SSL). SEL is a simple strategy that uses existing
products and technology to reduce energy use in commercial buildings. The concept behind SEL
is that a significant amount of energy can be saved by using lamps that have less light output, but
higher correlated color temperature (CCT). Lamps with higher CCT appear brighter than those
with lower CCT, so the actual light output of higher CCT lamps can be decreased, while
maintaining equivalent perceived brightness and visual acuity. Unlike other energy efficiency
strategies, SEL is not a technology — it's a different way to quantify light that can be used with
any type of lighting design to improve energy performance. Energy savings are achieved by
using high performance and high CCT lamps coupled with lower ballast factor, extra efficient
electronic ballasts (DOE 20091).

SSL utilizes light-emitting diodes (LEDs), organic light-emitting diodes (OLED), or polymer
light-emitting diodes (PLED) as sources of illumination rather than electrical filaments, plasma
(used in arc lamps such as fluorescent lamps), or gas.  The term "solid state" refers to the fact
that light in an LED is emitted from a solid object—a block of semiconductor—rather than from
a vacuum or gas tube,  as is the case in traditional incandescent light bulbs and fluorescent lamps.

The program's SSL research  aims to accelerate market introduction of high efficiency,  high-
performance SSL products. DOE's plan features two concurrent, interactive pathways. Core
technology research is conducted primarily by academia, national laboratories, and research
institutions. Product development is conducted primarily by industry on commercially viable
materials, devices, or systems. DOE and its  SSL partners have developed a multi-year R&D
plan to ensure that DOE is funding the appropriate R&D topics. The R&D roadmap is updated
annually with input from industry partners and workshop attendees, and guides the development
of annual SSL R&D solicitations.

DOE supports various  programs to encourage the latest SSL technology to successfully enter the
market,  one of which is the Commercially Available LED Product Evaluation  and Reporting
(CALIPER) program. CALIPER supports testing of a wide array of SSL products available for
general illumination. DOE allows its test results to be distributed in the public interest for
noncommercial, educational purposes. Over 120 products have been tested through the
CALIPER program to  date (DOE 2009m). Test reports and benchmark reports comparing LED
products to conventional technology are available at the program website:

5.4.c Review Considerations

309 Reviewers should identify whether energy efficiency requirements are addressed in EISs. It
is understood that rather than repeating a lengthy discussion on these requirements, the EISs will
most likely incorporate them by reference by citing the appropriate document. Many times these
documents are made available via a link to a web site in the EIS. In most cases, this should
suffice.

Reviewers should assess federal actions related to buildings and where appropriate encourage
compliance with requirements of the Energy Policy Act of 2005 and EO  13423-Strengthening
Federal Environmental, Energy, and Transportation Management.  The Act requires annual two
percent reductions in energy use at federal  agency buildings (including industrial and laboratory
facilities) through 2015, with DOE to complete a review of the government's performance in
response to this requirement by the end of 2014 and recommend additional measures for 2016
through 2025. Agencies must apply water conservation technologies if water is used to achieve
energy efficiency. EO 13423 strengthens this requirement by 50% to compel the reduction of
greenhouse gas emissions by three percent annually by 2015 or by 30 percent by the end of 2015
(using 2003 as the baseline).  EO 13423 also requires an annual two percent reduction in water

energy and water consumption reduction, and new facilities should include a plan for meeting

the federal requirements.  Facilities may be exempt from the energy reduction requirements if
they meet all of the following requirements:

•    Impracticability due to energy intensiveness or national security function;
•    Completed energy management reports;
•    Compliance with all energy efficiency requirements; and
•    Implementation of all cost-effective energy projects in the building.

The Energy Policy Act of 2005 also requires federal agencies to monitor electricity use in all
federal buildings by 2012, using advanced meters or devices that provide data at least daily.
DOE's Guidance for Electric Metering in Federal Buildings required implementation plans by
August 2006, and the meters must be installed, to the extent practicable, by October 1, 2012.
Reviewers should determine whether federal actions that involve existing buildings and new
construction have sufficiently addressed the electricity metering requirements of EPAct 2005 and
any implementing guidance.

Reviewers should determine whether any actions involving new construction meet EPAct 2005
requirements. This includes the requirement for new federal buildings to be designed 30 percent
below ASHRAE or International Energy Code standards and to incorporate sustainable design
principles. Reviewers could cite Greening Federal Facilities and the Federal Green
Construction Guide for Specifiers, among other resource guides, for sustainable and energy
efficient design.  EO 13423  additionally requires that buildings be constructed or renovated in
accordance with  the Guiding Principles for Federal Leadership in High Performance and
Sustainable Buildings set forth in the Federal Leadership in High Performance and Sustainable
Buildings MOU.

Reviewers should, where appropriate, encourage compliance with requirements of EO 13514.
The EO sets goals for federal agencies, including:
   •   managing existing building systems to reduce the consumption of energy, water, and
       materials, and identifying alternatives to renovation that reduce  existing assets' deferred
       maintenance costs;
   •   when adding assets to the agency's real property inventory, identifying opportunities to
       consolidate and  dispose of existing assets, optimize the performance of the agency's real-
       property portfolio, and reduce associated environmental impacts; and
   •   ensuring that rehabilitation of federally owned historic buildings utilizes best practices
       and technologies in retrofitting to promote long-term viability of the buildings.

Reviewers may want to recommend that buildings achieve LEED® and/or ENERGY STAR
certification. Both rating systems provide checklists of criteria that include energy efficiency
concerns. New federal construction should document the use of building commissioning (a
prerequisite for LEED® certification) and may want to frame the design and construction process
using the whole building design concept. Reviewers may want to recommend that projects make
use of specific building type energy and environmental design guidance offered by WBDG and
ASHRAE. More information on ASHRAE's initiatives to encourage energy efficiency in
existing buildings can be found in the 2009 GovEnergy presentation, "Sustaining our Future by
Rebuilding our Past: ASHRAE's Sustainability Goals: The Path Towards Net Zero Energy

Buildings" (http://www.govenergy.com/pdfs/presentations/Sustainability-
Session05/Sustainability-Session05-Holness.pdf) (Holness 2009).

Federal buildings should comply with all federal building energy codes.  Reviewers can suggest
the use of DOE Building Energy Codes software to determine compliance. Building envelope
(windows, doors, walls, roof and foundation materials) design should follow IECC and
ASHRAE 90.1 to maximize energy efficiency through appropriate insulation levels, window
glazing and optimized configuration.

Advanced HVAC technology, including Integrated Energy Systems should be considered for
new construction and retrofitting existing buildings.  Buildings should also employ passive
cooling methods, including tree and vegetative cover, cool pavements, and green or cool roofs.

10 CFR Part 436, Subpart A of Federal Energy Management and Planning Programs promotes
the use of and establishes a methodology and procedures for life cycle costing.  Reviewers may
want to recommend the NIST BEES model, which uses the life-cycle assessment approach to
measure the environmental performance of building products.

The Energy Independence and Security Act of 2007 requires all general purpose lighting in
federal buildings must use ENERGY STAR or FEMP-designated products by 2013.  In addition,
Reviewers can recommend the use of advanced fluorescent lighting, high intensity discharge
lighting, and LEDs where appropriate, and recommend occupancy sensors, time switches,
dimming systems and regular maintenance to retain lighting output over the life of the product.
Buildings should be designed to maximize interior daylighting.

Reviewers should, where appropriate, encourage compliance with the water efficiency-related
requirements of EO 13514. Reviewers can recommend that buildings develop a plan to manage
stormwater onsite, potentially recycle graywater for use within the building, use EPA
WaterSense labeled plumbing fixtures and xeriscape to reduce water use for landscaping. For
new multi-building facilities, Reviewers can recommend that the design minimize the energy
required for water supply by:
   •   Locating  areas that will receive water close and downhill to the sources of water and
       reclaimed water.
   •   Identify the end users of potable water and locate them near potable water sources.
   •   Locate wastewater treatment facilities near users of potable water.
   •   Locate sites to receive recycled wastewater near the wastewater treatment plant.
   •   Lay out pipes first, before the facilities, to eliminate the number of turns and bends
       required because these increase the need for energy and pumping.
   •   Increase the size of pipes and select pipe material to reduce the amount of friction which
       will reduce energy and pumping.
   •   Install solar hot water heaters.

Reviewers may recommend that indoor air quality be considered when implementing energy
efficiency measures. Additional potential indoor air quality-related safety measures include: a)
radon testing and mitigation; b) whole-building and local exhaust ventilation systems (ASHRAE

5.5 Federally Assisted Housing

5.5.a Summary

As early as 1974, the Housing and Community Development Act cited energy efficiency as a
specific objective in the development of affordable housing. Today, the U.S. Department of
Housing and Urban Development's (HUD) Office of Environment and Energy oversees HUD
energy initiatives and policies.  The 2002 HUD Energy Action Plan outlines HUD energy
initiatives, including promotion of ENERGY STAR products, improved monitoring of energy
efficiency in public and assisted housing, weatherization and other programs to improve
residential energy efficiency, internal training and technical assistance, and strengthening of
incentive programs for ESPCs (http://www.hud.gov/energv/energyactionplan.pdf). An ESPC is
an agreement with a utility company which, after performing an energy audit, provides financing
for recommended energy efficiency measures, oversees the installation of these measures, and
provides long-term services  such as monitoring of energy use, training of maintenance staff, and
energy education of residents (see Section  4.1).

The HUD Energy Action Plan also calls for increasing partnership efforts with EPA and DOE to
develop programs such as the CHP Screening Tool (which evaluates combined cooling, heating
and power in multi-family housing). The 2006 HUD report to Congress, Promoting Energy
Efficiency at HUD in a Time of Change, summarizes HUD's continuing efforts to implement the
Energy Action Plan  (http://www.huduser.org/publications/destech/energvefficiencv.html).

HUD would prepare EISs for projects that  meet the following criteria (24 CFR 58.37):

•    The project would provide a site or sites for, or result in the construction of, hospitals or
     nursing homes containing a total of 2,500 or more beds.
•    The project would remove, demolish, convert or substantially rehabilitate 2,500 or more
     existing housing units  (but not including rehabilitation projects categorically excluded
     under § 58.35), or would result in the construction or installation of 2,500 or more housing
     units, or would provide sites for 2,500 or more housing units.
•    The project would provide enough additional water and sewer capacity to support 2,500 or
     more additional housing units. The project does not have to be  specifically  intended for
     residential use nor does it have to be  totally new construction. If the project is designed to
     provide upgraded service to existing  development as well as to serve new development,
     only that portion of the increased capacity which is intended to serve new development
     should be counted.

5.5.b Related Federal Partnership Programs

Weatherization Assistance Program

The Weatherization  Assistance Program (WAP), managed by the DOE Weatherization and
Intergovernmental Program  (WIP), assists  low-income families to permanently reduce their
energy bills by making their homes more energy efficient.  The WIP awards annual grants to
state weatherization programs and works in partnership with states and more than 900 local


                                          5-50                EPA Publication No. 315-R-09-001

                                                                            March 2010
                                         Energy Efficiency Reference for Environmental Reviewers
agencies to provide weatherization services.  DOE provides approximately 40% of
weatherization funding, while states, the U. S. Department of Health and Human Services Low-
Income Home Energy Assistance Program, and utilities contribute the remaining funds.

During the last 30 years, the Weatherization Assistance Program has provided weatherization
services to more than 5.6 million low-income families.  On average, weatherization reduces
heating bills by 32% and overall energy bills by $358 per year at 2008 prices. Cost-effective
measures to increase energy efficiency are tailored to the specific home and climate. Reducing
spending on energy bills can have positive secondary effects on low-income communities by
freeing up funds for other pressing needs (DOE 2009).  Weatherization not only helps low-
income families save money, but it also lowers energy consumption as a whole.

The program is supported by the Weatherization Assistance Program Technical Assistance
Center website, http://www.waptac.org/, run by the Oak Ridge National Laboratory. This site
provides weatherization  practitioners and other energy conservation professionals with program-
related information.  The Center offers the Weatherization Assistant software, an energy audit
software tool developed  for the WAP, containing the National Energy Audit Tool for site-built
single-family houses and the Manufactured Home Energy Audit for mobile homes.

The WIP program has begun providing grants under the Energy Efficiency and Conservation
Block Grant (EECBG) Program, funded for the first time under the American Recovery and
Reinvestment Act of 2009. This Program, authorized in Title V, Subtitle E of EISA 2007,
provides funds to units of local and state government, Indian tribes, and territories  to develop and
implement projects to improve energy efficiency and reduce energy use and fossil  fuel emissions
in their communities. More information can be found at: http://www.eecbg.energy.gov/.

EPA Sector Notebooks

The Sector Notebook series is a unique set of profiles containing information for specific
industries and governments. Unlike other resource materials, which are organized by air,  water,
and land pollutants, the Notebooks provide a holistic approach by integrating processes,
applicable regulations and other relevant environmental information. There are 33  Industry
Sector Notebooks and 3  Government Series that provide government officials with information
they need to comply with the environmental regulations that apply to their activities. Many of
them may provide useful information for the NEPA reviewer.  More information about the
Sector Notebooks can be found in the Sector Notebook Factsheet located at:
http://www.epa.gov/compliance/resources/publications/assistance/sectors/notebooks/sector-
notebooks-factsheet.pdf.  The notebooks can be accessed at:
http://www.epa.gov/compliance/resources/publications/assistance/sectors/notebooks/.

5.5.c Review Considerations

309 Reviewers should identify whether energy efficiency requirements are addressed in EISs.  It
is understood that rather than repeating a lengthy discussion on these requirements, the EISs  will
most likely incorporate them by reference by citing the  appropriate document.  Many times these
                                          5-51                 EPA Publication No. 315-R-09-001

                                                                            March 2010
                                         Energy Efficiency Reference for Environmental Reviewers
documents are made available via a link to a web site in the EIS. In most cases, this should
suffice.

Many of HUD's programs that support energy efficiency, such as subsidizing utility expenses in
assisted housing or energy assistance for low-income households, are not likely to be the subject
of assessment in EISs reviewed by EPA. However, community redevelopment and similar
projects are often partially or fully funded by HUD, requiring NEPA compliance. EPA has
reviewed EISs for eight projects proposed, or proposed to be funded, by HUD that met these
criteria in the period January 2004 through March 2009. On one of these EISs (LMDC 2004),
energy efficiency-related comments by EPA and other commenters included requests for
clarification, revision, additional contingency planning, or mitigation related to the following
issues, which serve as a useful checklist for reviewing future EISs:

•    Water use in fountains and planning for drought emergencies.
•    Total demand on the electrical supply grid.
•    Means to reduce power use burdens on environmental justice communities.
•    Potential to add onsite energy generation.
•    Water conservation.
•    Commitment to sustainable design guidelines.
•    Stormwater capture and reuse.
•    Use of electric-powered construction equipment.

In addition to these issues, EPA reviewers may request that HUD EISs consider reporting the
results of a screening assessment as to the feasibility of incorporating cogeneration (CHP) into
the project (EPA 2008). Promoting CHP in public or assisted housing is one of the action items
in HUD's Energy Action Plan (HUD 2003).

The increase in the per facility allocation available under the new ARRA funding allows for
additional treatments beyond the traditional weatherization program energy efficiency measures.
The convergence of available monies with the emergence of new micro CHP technologies, could
proffer additional opportunities to improve economic, energy and environmental benefits. This
opportunity is particularly acute in the multifamily sector, which serves a significant portion of
public or assisted housing.

The following elements that would support the attainment of energy conservation could be
considered by HUD for incorporation into its proposed actions and alternatives, particularly the

5.6 Military Installations

5.6.a Summary

The U.S. Department of Defense (DoD), including the military branches of the U.S. Army
(Army), U.S. Navy (Navy), U.S. Marine Corps (Marines) and U.S. Air Force (Air Force),
occupy and operate more than 5,400 sites comprising over 316,200 individual buildings and
229,400 other structures in the U.S. and abroad (valued at more than $455 billion dollars). These
facilities cover approximately 29.8 million acres, with more than 98% located within the United
States and its territories (DoD 2008). The DoD operates from over 2.2 million square feet of
building space. Buildings and facilities account for approximately 25% of total DoD energy use.

In FY 2008, the DoD spent $3.95 billion on facility energy, and an additional $16 billion on fuel
for non-fleet and fleet vehicles, including automotive gasoline, LPG-propane, aviation gasoline,
jet fuel, diesel-distillate, and other Navy-specific fuel. Accordingly, the DoD is the largest single
energy consumer in the country, representing approximately 78% of the entire energy consumed
by the federal government  (DoD 2009a). Within DoD, the Air Force is the largest energy
consumer, accounting for 64% of total DoD energy use with aviation fuel the major component.
The Navy/Marines and Army account for 19% and 17%, respectively, of DoD energy
consumption.

The term 'military installation' means a base, camp, post, station, shipyard, center, homeport
facility, or any other activity under the jurisdiction of a department, agency, or other instrument
of the Department of Defense, including a leased facility (GlobalSecurity.Org 2005). The term
military installation does not include facilities used primarily for civil works, rivers and harbor
projects,  or flood control projects (i.e. those activities commonly under the management of the
U.S. Army Corps of Engineers).

Conserving energy and investing in energy reduction measures makes good business sense and
allows limited resources to be applied to readiness and modernization. The DoD has already
reduced its installation energy consumption significantly; by FY 2005 the DoD achieved a
reduction in energy consumption by 28.3 percent as compared to a FY 1985 baseline. The
Energy Policy Act of 2005 changed the baseline to FY 2003. DoD achieved a 10.1% reduction in
goal facilities energy intensity for FY 2007. Despite this  success, the DoD must make greater
strides in energy efficiency and consumption reduction in order to meet the vision of providing
reliable and  cost effective utility services to the warfighter. Dramatic fluctuations in the cost of
energy significantly impact already constrained operating budgets, providing even greater
incentives to conserve and  seek ways to lower energy consumption. These  include investments in
cost-effective renewable energy sources, energy efficient construction designs, and aggregating
bargaining power among regions and services to procure the most favorable energy contracts
(DoD 2009b).

U.S. Army

The U.S. Army is comprised of almost 1.3 million personnel, including active, guard, reserve
and civilian  employees, at over 2,200 locations worldwide. The Army operates from over

143,000 buildings covering 955 million square feet, and is also responsible for 71,315 other
structures. The Army manages approximately 52% of DoD lands, over 15.4 million acres (DoD
2008).

Energy consumption in Army facilities consists of approximately 1/3 electrical energy, with the
remainder being thermal energy supplied primarily by natural gas and increasingly less fuel oil
(Figure 5-2).

Energy Strategy

The U.S. Army developed the "Army Energy Security Implementation Strategy" to address
energy use and efficiency efforts across the Army enterprise. This document presents the Army's
overall energy security vision, mission, and goals, with direction on the development of
objectives and metrics to gauge progress toward such goals. The Army's energy security mission
is to make energy a consideration in all Army activities in an effort to reduce demand, increase
efficiency, seek alternative sources, and create a culture of energy accountability, while
sustaining or enhancing operational capabilities.

Army Energy Security Implementation Strategy

Surety, Survivability, Supply, Sufficiency, Sustainability - these are the core characteristics
defining the energy security necessary for the full range of Army missions. Energy security for
the Army means preventing loss of access to power and fuel sources (surety), ensuring resilience
in energy systems (survivability), accessing alternative and renewable energy sources available
on installations (supply), providing adequate power for critical missions (sufficiency), and
promoting support for the Army's mission, its community, and the environment (sustainability).

The strategy outlines the five Strategic Energy Security Goals to improve the Army's overall
energy security posture and assure access to critical power across the full spectrum of Army
missions:

    •   Reduced Energy Consumption: Reduce the amounts of power and fuel consumed by the
       Army at home and in theatre.  This goal will assist in minimizing the  logistical fuel tail in
       tactical situations by improving fuel inventory management and focusing installation
       consumption on critical functions.
    •   Increased Energy Efficiency Across Platforms and Facilities: Raise the energy efficiency
       for generation, distribution, storage and end-use of electricity and fuel for system
       platforms, facilities, units and individual  Soldiers and Civilians. This goal also relates to
       the productivity of a system based on energy requirements and supports the ability to
       make informed trade-offs in development, engineering and deployment of weapon
       systems.
    •   Increased Use of Renewable / Alternative Energy:  Raise the share of
       renewable/alternative resources for power and fuel use, which can provide a decreased
       dependence upon conventional fuel sources. This goal also supports national goals
       related to renewable/alternative energy.
    •   Assured Access to Sufficient Energy Supplies: Improve and maintain the Army's access
       to sufficient power and fuel supplies when and where needed. Energy is a critical
       resource in conducting Army missions.  Vulnerabilities to external disruption of power
       and fuel sources should be minimized and the potential for industry partnerships to
       enhance energy security and generate net revenues for the Army should be considered.
    •   Reduced Adverse Impacts on the Environment: Reduce harmful emissions and discharges
       from energy and fuel use. Conduct energy security activities in a manner consistent with
       Army environmental and sustainability policies.

Army Energy and Water Campaign Plan for Installations

As a major component of the U.S. Army's energy posture, the "Army Energy and Water
Campaign Plan for Installations"  specifically addresses energy efficiency and water use at Army
installations.  The goal of this plan is to assist the Army in  providing safe, secure, reliable,
environmentally compliant, and cost-effective energy and  water services to soldiers, families,
civilians, and contractors on Army installations.  The plan sets the general direction for Army
installations with five major initiatives:

    •   Eliminate energy waste in existing facilities.

U.S. Navy/U.S. Marine Corps

For FY2005, the Navy and Marine Corps were supported by a combined personnel group of
approximately 860,000, with about 544,000 active personnel, 123,000 reserve personnel, and
193,000 civilian employees. These services collectively manage over 91,000 buildings
comprising over 600 million square feet and 88,700 other structures. The services manage over
4.5 million acres of land.

U.S. Marine Corps Energy Strategy

The Marine Corps Facilities Energy and Water Management Program authored the energy
strategy campaign plan, "Ten x 10: Top 10 Things To Do by 2010 to Reduce USMC Energy
Risks." The plan focuses on three long-term energy goals:

   •  Reduce energy intensity 30% by 2015 relative to 2003 baseline.
   •  Reduce water consumption intensity 16% by 2015 relative to 2007 baseline.
   •  Increase the percentage of renewable electrical energy consumed to 25% by FY 2025.

The plan also lists ten strategies for achieiving these long term goals:

   •  Create an organizational structure that maintains a command committed to the efficient
      use of energy and water resources.
   •  Provide management and resources for the execution of facilities energy and water
      management programs.
   •  Use an integrated approach to optimize energy performance to meet Federal building

Department of the Navy Energy Strategy

While the Navy does not currently have a specific energy management or energy efficiency
strategy for installation management, a number of policies and instructions relate specifically to
energy-related considerations in the renovation and construction of Navy facilities.

The operational impacts of a volatile energy market resulted in the Chief of Naval Operations
(CNO) establishing Task Force Energy (TFE) to transform the disparate and decentralized Navy
energy programs through top-down commitment and centralized governance, and emphasizing a
need for further energy efficiency as a strategic imperative in the CNO 2009 guidance.

The TFE is developing a Navy Energy  Strategy to formulate an overarching governance to
reduce demand, increase alternative/renewable power generation, and provide secure energy for
critical infrastructure and operations. It establishes the shore and tactical community pillars with
functional platforms to optimize energy security, investments and policy/doctrine.  Upon full
implementation, the Navy strategy will: enable a culture where energy is valued as a strategic
resource; be a leader in environmental stewardship; make energy an operational advantage; and
minimize the impacts of energy market volatility.

Department of the Navy Environmental Strategy

The Department of the Navy Environmental Strategy empowers every sailor, marine and civilian
employee to take a proactive role in protecting the environment, helping the Navy to meet
mission requirements, protect and enhance the environment, build equity with internal and
external stakeholders, manage and reduce costs, and enhance the commitment to environmental
stewardship. A goal of the strategy related to energy efficiency states "Personnel shall
incorporate pollution prevention principles, adopt a "green procurement" philosophy, and
employ technology to meet DoD environmental  stewardship objectives  where efficiency and
economics warrant with an overall objective of reducing the department's environmental
footprint. Energy efficiency, use of alternative energy sources including sustainable energy
sources, and energy conservation initiatives shall be considered in every acquisition program
consistent with warfighting requirements."

Secretary of the Navy Instruction 4100.9A, Department of the Navy Shore Energy
Management,  October 2001

U.S. Air Force

The U.S. Air Force operates throughout the world at 84 major and 82 minor installations, on over
9.8 million acres. The service is supported by an estimated 700,000 employees, including active
military, civilian, guard and reserve personnel.  The Air Force operates from 81,900 buildings
covering 655 million square feet. The service is also responsible for over 56,000 structures.

The Air Force is the largest energy consumer in the federal government. Aviation is the largest
energy user, accounting for 81% of the total energy consumption of the Air Force. Facilities and
installations account for approximately 15%  of energy use, with vehicles and other ground
equipment consuming about 4%. In FY 2007, the Air Force spent over $7 billion in energy costs
(Figure 5-3).

Energy Strategy

To address energy sustainability concerns, the Air Force has developed a strategic vision to
provide leadership in utilizing new energy options that include secure and reliable energy
alternatives and increased energy-use efficiency. The three major strategies are:

   •   Reduce demand: The Air Force is committed to increasing energy efficiency and
       awareness of the need to reduce energy consumption. This has led to a more than 16%
       reduction in facility energy usage in FY 2008 compared to FY 2003, equating to a

                                          Energy Efficiency Reference for Environmental Reviewers
       savings of 6 trillion BTUs and $90 million in savings —making the Air Force one of the
       biggest energy savers in the country.
    •   Increase supply: The Air Force is committed to research, testing, and certifying new
       technologies, as well as renewable and sustainable resources in order to create new
       domestic sources of supply. This includes leveraging advances in renewable energy
       sources such as geo-thermal, wind, biomass and solar power and alternative synthetic
       fuels derived from coal, natural gas, and biomass.
    •   Culture change: The Air Force is seeking to increase awareness of energy concerns,
       creating a culture where personnel make energy a consideration in every action and
       decision. By focusing on leadership efforts, training, curricula, and communication, the
       Air Force is building the foundation for a culture that will continuously reduce energy
       consumption. This strategy seeks to create a cultural change similar to previous
       awareness and behavioral changes created by safety and environmental programs.

In concert with these broad strategies, the Air Force has identified the following major statutory
and policy goals to achieve a more secure and reliable energy portfolio:

    •   Reduce facility energy intensity 3% annually.
    •   Reduce base water use 2% annually.
    •   Increase use of renewable energy at annual targets, culminating in 25% goal by 2025.
    •   Reduce ground vehicle fossil fuel use 2%  annually.
    •   Increase alternative fuel use 10% annually.
    •   Obtain 50% of domestic aviation fuel blend from "green sources" by 2016.

Air Force Installations and Infrastructure

In order to implement the components and meet the goals of the Air Force energy strategy,
installation programs and actions are focused in four major areas: improving current
infrastructure; improving future infrastructure; expanding use of renewable energy; and
managing costs.

Improving Current Infrastructure

Efforts in this area focus on increasing energy efficiency in current facilities, vehicles, and
equipment, and actively conserving water through actions such as improving building envelope
thermal resistance; installing energy efficient lighting; recommissioning building systems;
maximizing space utilization; rightsizing vehicle fleet;  and replacing inefficient system
machinery with high-efficiency components.

Some of the major actions to improve current infrastructure include:

    •   Develop policy/guidance  for considering life-cycle costs for purchases of replacement
       machinery and parts related to energy and water consumption.
    •   Develop a strategic consolidation and demolition plan that considers requirements, utility
       savings, and financial savings targeted toward facilities with poor energy performance.

                                         Energy Efficiency Reference for Environmental Reviewers
    •   Increase use of water meters to document use and expand use of water distribution
       system leak detection and repair.
    •   Actively seek to improve overall fleet average miles per gallon while achieving 2%
       annual reduction in fossil fuel consumption.
    •   Increase awareness and consideration of low-speed vehicles for replacing medium-to-
       heavy duty vehicles, such as utility pickup trucks, vans and maintenance vehicles.
    •   Continue testing hydrogen vehicles and infrastructure at select installations.

Improve Future Infrastructure

Air Force actions for better future infrastructure involve improving processes and applying
sustainable energy-efficiency standards to accelerate the delivery of high-performance buildings,
alternative-fuel vehicles, and supporting infrastructure.

Some of the major actions to improve future infrastructure include:

    •   Starting in FY 2009, ensure that 100% of new construction is capable of achieving
       LEED® Silver certification,  5% is certified LEED® Silver, and 10% is certified LEED®
       Silver in FY 2010 and beyond.
    •   Develop metrics and measurement capabilities to track energy performance.
    •   Convert 30% of fleet to low-speed vehicles.
    •   Procure/construct/sustain alternate fuel stations, including installation of at least 1
       renewable fuel pump at each refueling center handling more than  100,000 gallons of fuel
       annually (Department of the Air Force 2008).

Expand Renewables

By promoting the development of renewable and alternative energy of use in facilities and
ground vehicles and equipment, the Air Force seeks to have 25% of base energy consumption in
FY 2025 be derived from on-base renewable generation. These efforts will increase energy
supply, decrease stress on the national electrical grid, and provide security benefits to ensure the
sustainability of military operations.

Some of the major actions to expand the use of renewable energy include:

    •   Construct on-base renewable energy production to achieve 1% of total Air Force
       consumption by FY 2012.
    •   Expand testing and deployment of hydrogen vehicles and fuel infrastructure where cost-
       effective.

Manage Costs

As the major energy user in the DoD, measures to reduce Air Force costs through utility terms,
service and contract are of utmost importance. Cost planning, negotiation and litigation of utility
rates, accounting management, timely bill payment,  and cost-avoidance education are each
important components of the Air Force cost management strategy.

                                         Energy Efficiency Reference for Environmental Reviewers
Some of the major actions to address energy cost efficiency include:

    •   Perform utility acquisition evaluations at 10 bases annually to determine the best rate
       schedule and most favorable contract terms.
    •   Develop and implement a utility contract training program.
    •   Partner with DoD to advertise current rebates, incentives and credits for utilities and
       renewable energy to maximize use on Air Force installations.

Air Force Aviation

Efforts to improve the energy efficiency of Air Force aviation operations involve actions to meet
the three major energy strategy components of reducing demand, increasing supply and changing
culture.

Reducing Demand

To reduce demand, Air Force efforts are concentrated on improving aircraft design and
operations. Optimized aerodynamic research into new aircraft wing and body configurations seek
to reduce drag and associated fuel demand. The use of lighter and stronger alloy and composite
materials in aircraft construction can reduce structural weight and improve fuel efficiency.
Advancements in propulsion and engine technologies can result in improvements in the amount
of thrust derived from each gallon of fuel, thereby improving fuel economy. Improvements in
mission and route planning can reduce unnecessary flight time and fuel use. Increased use of
flight simulators for training programs directly reduces fuel consumption while reducing the
stress and maintenance fleet costs. Finally, the Air Force is seeking to maximize the use of
advanced avionics and stealth unmanned aerial systems to accomplish missions with greater
success at reduced energy consumption.

Increasing Supply

This component is mainly focused on developing implementation of alternative fuel sources.
Currently, the Air Force has certified its entire B-52 fleet to operate on a 50/50 blend  of synthetic
fuel and JP-8 aviation fuel. This synthetic fuel is derived from coal, natural gas or biomass
feedstocks. Testing with other Air Force aircraft is underway to evaluate the performance of this
blend for wider use. This synthetic blend burns cleaner than conventional petroleum products
and produces fewer particulates and no sulfur dioxide.

5.6.c Review Considerations

309 Reviewers should identify whether energy efficiency requirements are addressed in EISs.  It
is understood that rather than repeating a lengthy discussion on these requirements, the EISs will

                                         Energy Efficiency Reference for Environmental Reviewers
most likely incorporate them by reference by citing the appropriate document.  Many times these
documents are made available via a link to a web site in the EIS.  In most cases, this should
suffice.

In reviewing DoD and service installation projects, Section 309 reviewers should consider
highlighting energy efficiency commitments and project components against applicable DoD and
service policies and guidance.

As installations routinely involve a variety of buildings and equipment, reviewers should consult
other sections of this reference document specific to the components of the proposed action.
Specific considerations to determine compliance with EPAct 2005 and EO 13423 include:

   •   Confirming applicable LEED design and certification.
   •   Evaluation of results of energy audits, as applicable.
   •   Review of alternative fuel vehicle commitments.  A good source of information is the
       annual AFV reports produced by each service found at:
       https://www.denix.osd.mil/portal/page/portal/denix/environment/AFV.
   •   Commitments to use of alternative and/or renewable sources of energy either generated
       on-site or procured from an outside energy provider.
   •   For an assessment of compliance with applicable building standards, reviewers should
       consult the DoD Unified Facilities Criteria program at
       http://www.wbdg.org/references/pa DoD.php.

Under EISA 2007,  agencies must identify all "covered facilities" that constitute at least 75% of
the agency's facility energy use. A covered facility may be defined as "a group of facilities at a
single location or multiple locations managed as an integrated operation." Section 431 of EISA
requires that total energy use in federal buildings, relative to the 2005 level, be reduced 30% by
2015. DoD has identified "covered facilities" relative to EISA. Projects involving these facilities
should receive additional scrutiny in terms of documentation of energy reduction and efficiency
components. A list of EISA facilities is provided in the DoD Annual Energy Report at
http://www.acq.osd.mil/ie/energv/energymgmt  report/main.shtml.

5.7 Laboratories

5.7.a Summary

Laboratories can be defined as buildings that contain areas where isolated operations are
performed with hazardous/toxic or precious/delicate materials. This isolation is accomplished
through the air balance/pressure relationship to adjacent areas. The pressure relationship is either
negative for hazardous isolation for handling hazardous/toxic operations, or positive for
protective isolation for handling precious/ delicate operations. Characteristics of the laboratory
environment that are coupled tightly with energy use include ventilation rates, temperature
requirements, humidity requirements, filtration efficiency, and fume hoods (LBNL 1996).

Cleanrooms are specially constructed enclosed areas that are environmentally controlled with
respect to airborne particulates, temperature, humidity, air flow patterns, air motion, and lighting.
They are sealed facilities with specialized air handling and filtration systems designed to
minimize static electricity or the concentrations of particles and other contaminants that may
interfere with scientific research, manufacturing, medical  operations and other activities. (LBNL
1996).

Laboratories are sophisticated and complex environments that are designed to meet the special
demands of experimental study, testing, and analysis and to provide safe environments for
workers. This double mission means that laboratories must provide levels of safety, space
conditioning, and indoor air quality not usually maintained in conventional office buildings. To
this end, designs of research laboratories typically use far more energy and water per square foot
than an office building (EPA 2009a). A study by Lawrence Berkeley National Laboratory
(LBNL) noted that energy intensities are four to five times higher than those found in ordinary
buildings in California. In the case of cleanrooms, intensities are 10-100 times higher,
depending on the cleanliness classification (LBNL 1996).

Laboratories intended for research and those intended for production differ from an energy
standpoint. Research laboratories (especially those located in university settings) have very
irregular operating patterns, seasonally as well as diurnally. Because of this, the diversity of
loads is of critical importance in design of HVAC systems. Energy management strategies based
on control (of lighting, ventilation, etc.) offer particular promise in research laboratories where
occupancy varies or the need for certain processes is sporadic (LBNL 1996).

Production laboratories, on the other hand, tend to be used very intensively. As a result, loads are
relatively level. Around-the-clock operation is not uncommon, especially for cleanrooms where
the importance of maintaining high-quality  environmental conditions means that the ventilation
is turned off only when absolutely necessary (even if there is a pause in the production  process).
Interruptions of production for the sake of energy-management interventions are far less
acceptable in a (commercial) production laboratory where downtime is extremely costly. Lastly,
in production laboratories energy costs are very small in proportion to the value of production,
while in research laboratories they  can represent a relatively high share of total costs (LBNL
1996).

                                          Energy Efficiency Reference for Environmental Reviewers
DOE's National Laboratories and other facilities represent major laboratory-type facilities in
many parts of the country, and represent the full range of laboratory functions. Energy data for
the National Laboratories is compiled by DOE, and is reported annually according to FEMP
requirements.

Recognition of load diversity is a key factor in energy-efficient laboratory design. Each
laboratory facility will be operated in a unique manner commonly referred to as the "Profile of
Use." Laboratory designers/operators must determine the potential variation of energy loads on
hourly, daily, annual, and life-cycle bases and take steps to minimize these loads. The main
energy loads that need to be minimized are:

•    Thermal (sensible), e.g., heating and cooling;
•    Latent, e.g., humidification or de-humidification;
     Air movement, e.g., fans and motors/drives;
     Circulation, e.g., pumps and motors/drives; and
•    Miscellaneous support and peripheral equipment.

LBNL offers a list of barriers to energy efficient design. Barriers include:

•    Using standard design practices that are based on  old technologies or inaccurate
     assumptions.
     Conservative facility building culture, short supply of designers who are familiar  with
     energy-efficiency concerns in laboratory facilities, and a risk of legal consequences if the
     laboratory's operation does not meet design specifications/design basis documents.
.    Emphasizing initial cost of systems, instead of life-cycle costing.
     Lack of benchmarking of energy costs.
     Size limitations for code requirements that may adversely affect environmental
     conditioning system designs.
•    Inadequate space may be available for energy-efficient equipment. Currently, the  architect
     often designs the facility and then tells the engineers  how much space they have. Early
     cooperation between the design team members is  necessary to devise optimum
     configurations.
.    Performance envelope specifications may limit possibilities for energy efficiency. When
     the performance envelope, i.e.  operating range of the facility,  can be expanded—for
     example, increasing the allowable relative humidity—lower initial costs and operational
     energy costs may result.

LBNL authored^ Design Guide for Energy-Efficient Research Laboratories
(http://ateam.lbl.gov/Design-Guide/). which uses a comprehensive systems design  approach to
improving energy efficiency.  The guide emphasizes  "right sizing," choosing the most efficient
and cost effective combinations of equipment and equipment sizes as well as managing the
laboratory load, to reduce energy consumption and operating costs. The guide also recommends
building commissioning (see Section 5.4, Buildings) to maximize efficiency.
                                          5-70                EPA Publication No. 315-R-09-001

                                         Energy Efficiency Reference for Environmental Reviewers
The guide also recommends:

     An energy monitoring and control system (EMCS) that incorporates direct digital control
     (DDC).
•    Variable Frequency Drives (VFD). The VFD's lower air velocity reduces pressure loss and
     increases operating efficiency of a heat recovery device. When the laboratory is
     unoccupied, the air flow rate could be reduced by 50%, decreasing the energy consumption
     of the entire air handling system to less than 25% of that required for a conventional
     system.
     Modularized Plant Devices. Conditioning equipment can be designed in modules that can
     operate singly or together to meet part or full loads. Modules include multiple boilers and
     chillers that can have their operation staged to meet the load. Devices whose operation can
     be modulated include: variable air volume (VAV) supply and fume hood exhaust systems
     and variable frequency drives (VFDs) on fans and pumps.
     Segregating Tasks with Mini-Environments. Laboratory temperature and humidity design
     conditions are typically specified to satisfy both process and human comfort needs.
     Segregating critical  areas with narrow environmental tolerances from other non-critical
     areas saves energy. One method is to subdivide systems and zones into mini-environments.
     Indirect-Direct Evaporative Cooling. The higher the allowable humidity, the greater the
     energy savings. As the allowable humidity range increases, the use  of energy-efficient
     indirect-direct evaporative cooling becomes more appropriate. Laboratories in warmer
     climates benefit from raising the allowable relative humidity; laboratories in colder
     climates benefit most from lower minimum relative humidity specifications, as well as a
     wider range.
.    Efficient Lighting. Lighting  should be designed to incorporate both dedicated task
     illumination and general ambient lighting. High-efficiency lighting components, such as
     fluorescent lamps and solid state lighting, should be used. Lighting energy consumption
     can also be reduced by control systems that turn off lights based on occupancy or adjusts
     lighting in response to available natural light. In some laboratories,  a remote lighting
     system provides the benefit of isolating a large portion of the lighting system from the
     laboratory space.
.    Efficient Duct Systems.  Small ductwork in laboratories is often routed circuitously,
     resulting in significant energy waste. The design of an energy-efficient air distribution
     system should be an iterative process which incorporates life-cycle  cost. A key to saving
     energy is to reduce the friction loss of the air distribution system by using large-diameter,
     round ductwork,  efficient fittings, lower coil and filter face velocities, and energy-efficient
     noise attenuators.
     Heat Recovery Ventilation. Energy recovery systems typically incorporate heat exchange
     equipment to reduce energy costs by extracting heat from the facility's exhaust air stream
     before it is vented outside. Energy recovery from the laboratory's exhaust should be
     considered when significant portions of operating hours are at ambient temperature of 50°F
     (10°C) and below. Another recoverable energy source is provided by chiller/DX
     condensers. Water cooled condensers can be piped to reject waste back into the lab's
     HVAC  system to provide reheat capacity, to augment run-around coil systems, and to dry
     regenerative heat wheels. The four major energy recovery systems include run-around coil
     systems, regenerative heat wheels, heat pipes, and fixed-plate exchangers.

•    Economizer Cooling.  Laboratories, research facilities, clean rooms, and hospitals require
     large amounts of outside make-up air. These facilities can only benefit from economizers
     when the facility does not require 100 percent outside make-up air. Exhaust air from the
     facility may be added into this outside make-up air stream with an economizer to save
     energy. Inadequate mixing of the make-up air stream and the exhaust (return) air will
     defeat the function of economizer. Consequently, errors made by the mixed-air temperature
     sensor can increase annual energy consumption by as much as 30 to 50 percent. To
     maximize the savings from economizer system, proper blending and sensing of the air
     streams must occur.
•    Demand-controlled ventilation.  During periods of non-occupancy or low level of process
     activity in research laboratory or cleanroom facilities,  recirculation ventilation rates can be
     reduced. Sensors can monitor and control ventilation rates, meeting occupant safety and
     process requirements and minimizing energy consumption. A great amount of "free"
     cooling can be realized by using a demand-controlled ventilation scheme the takes
     advantage of cooler evening temperatures.

Another reference for  laboratories is the 2002 Los Alamos National Laboratory Sustainable
Design Guide
(http://appsl.eere. energy. gov/buildings/publications/pdfs/commercial_initiative/sustainable_guid
e chl.pdf), which focuses on issues and design processes for energy efficient buildings at
LANL, and how these processes can be used for other laboratories.

5.7.b Related Federal Partnership Programs

Labs21

Laboratories for the 21st Century (Labs21) is a voluntary partnership program co-sponsored by
EPA and DOE to improve the environmental performance of U.S. laboratories. It is open to all
U.S. public and private sector laboratories, and provides training and technical assistance,
including the Design Guide for Energy Efficient Research Labs, Best Practice Guides and
Technical Bulletins on design, construction, and operation of specific energy efficiency and
sustainable technologies for laboratories. The primary guiding principle of the Labs21
approach is that improving the energy efficiency and environmental performance requires
examining the entire facility from a whole building perspective.

The program also offers a web-based  Energy Benchmarking Tool (http://labs21 .lbl.gov/)  that
allows laboratory owners to compare  the performance of their laboratories to similar facilities
and help identify potential energy cost savings opportunities.

The Labs21  Design Intent Tool (http://www.labs21century.gov/toolkit/intent tool.htm) is a
database that records design decisions that impact a lab's energy efficiency. Designers can plan,
monitor, and verify that a facility's design intent is being met during each stage of the design
process. Additionally,  the tool gives commissioning agents, facility operators, and future
renovators an understanding of how the building,  and its subsystems, were, and are, intended to
operate. Thus, tracking and benchmarking energy efficiency performance is  enhanced.

                                          Energy Efficiency Reference for Environmental Reviewers
The Labs21 Design Process Manual
(http ://www.labs21 century, gov/toolkit/process  manual .htm) is a web-based tool that provides
step-by-step guidance of the design process for a high-performance laboratory, leveraging all of
the other Labs21 tools. Highlights include a checklist of action items for each stage of the
building design and delivery process, with links to relevant Labs21 tools, and a quick-reference
list of sustainable design strategies, with links to Labs21 EPC credits, Best Practice Guides,
Design Guide, and case studies.

The Labs21 Environmental Performance Criteria (EPC) is a rating system specifically designed
for laboratory facilities. It builds on the LEED® Green Building Rating System.  The EPC was
produced by a series of working groups that included architects, engineers, facility managers,
and health and safety professionals.  The EPC has been recently updated to version 2.2 and is
available at: http://www.labs21century.gov/toolkit/epc.htm.

EPA Sector Notebooks

The Sector Notebook series is a unique set of profiles containing information for specific
industries and governments. Unlike other resource materials, which are organized by air, water,
and land pollutants, the Notebooks provide a  holistic approach by integrating processes,
applicable regulations and other relevant environmental information. There are 33 Industry
Sector Notebooks and 3  Government Series that provide government officials with information
they need to comply with the environmental regulations that apply to their activities. Many of
them may provide useful information for the NEPA reviewer. More information about the
Sector Notebooks can be found in the Sector Notebook Factsheet located at:
http://www.epa.gov/compliance/resources/publications/assistance/sectors/notebooks/sector-
notebooks-factsheet.pdf.  The notebooks can be accessed at:
http://www.epa.gov/compliance/resources/publications/assistance/sectors/notebooks/.

5.7.c Review Considerations

309 Reviewers should identify whether energy  efficiency requirements are addressed  in EISs.  It
is understood that rather than repeating a lengthy discussion on these requirements, the EISs will
most likely incorporate them by reference by  citing the appropriate document. Many  times these
documents  are made available via a link to a web site in the EIS. In most cases,  this should
suffice.

See Section 5.4, Buildings for Review Considerations for new construction and retrofitting of
federal buildings.

The first step for reviewers will be to understand the purpose of the proposed laboratory or
proposed changes to an existing laboratory. Reviewers should be aware of the different energy
needs/issues related to research and production laboratories.  Research laboratories will need to
account for irregular operating patterns in planning to minimize energy use, while production
laboratories will have an intensive, and more  constant energy load.

                                         Energy Efficiency Reference for Environmental Reviewers
Reviewers may want to suggest that laboratories achieve certification under LEED® for
Laboratories, and/or complete the checklist for the related Labs21 Environmental Performance
Criteria (EPC) rating system.

Reviewers should review the LBNL list of barriers to energy efficiency at laboratories listed
above, and identify any barriers present in the proposed project.  The LBNL Labs 21 Design
Guide for Energy-Efficient Research Laboratories (http://ateam.lbl.gov/Design-Guide/)(as well
as Best Practice Guides and Technical Bulletins) offer comprehensive, specific recommendations
for reviewing proposed projects from an energy efficiency standpoint.

The Labs21 federal partnership program also offers a number of tools that Reviewers can
recommend, including the Energy Benchmarking Tool,  Design Intent Tool, and Design Process
Manual.

5.8 Industrial Facilities

5.8.a Summary

Industry is a large and diverse energy-consuming sector in the United States. As of 2007,
industry was responsible for more than one-fifth of U.S. energy consumption (see Figure 1-2)
(EIA 2007, DOE 2003). Approximately 8 percent of this energy is lost during power generation
and transmission before electricity arrives at industrial plants. Natural gas, petroleum products,
and electricity comprise the major energy sources used to heat and power U.S. factories, farms,
mining, and construction operations. In addition to heat and power, industry uses fossil fuels as
feedstock to produce industrial materials and products such as chemicals and plastics (DOE
2003).

Unlike other sectors, energy use in industry is often determined by the specific industrial process
in use. These inherent variations inhibit a "one-size-fits-all" approach to energy efficiency.
However, some important energy applications are common across industry. As a result,
industrial energy efficiency opportunities exist in both process-specific and crosscutting energy
systems (DOE 2003).

As part of its Industrial Technologies Program (see 5.8.b Related Federal  Partnership Programs),
DOE creates energy footprints that map the flow of energy supply, demand, and losses in U.S.
manufacturing industries. Identifying the sources and end uses of energy helps to pinpoint areas
of energy-saving opportunities, and provides a baseline to calculate the benefits of improving
energy efficiency.  Each footprint represents an average picture  of energy use for each industry
and illustrates:

    •  The portion of energy that is purchased from  utilities, generated onsite, and transported to
       the local grid.
    •  Where and how energy is used within a typical plant.
    •  Where energy is lost due to inefficiencies, both inside and outside the plant.

Energy losses shown on the footprints indicate immediate opportunities to improve efficiency
and lower energy consumption by implementing best energy management practices, improved
energy systems, and new technology (DOE 2009m).  Figures 5-4 through 5-6 show the energy
footprints in three levels of detail for the manufacturing sector as a whole. Footprints are also
available for specific industries at:
http://wwwl.eere.energy.gov/industry/program  areas/footprints.html.

Many industrial waste products can be recycled. When materials are reused or recycled, energy
use is avoided.  In addition, virgin resources are conserved and virgin mining impacts are
avoided.  Table 5-6 lists secondary use markets for common industrial waste products.

Within manufacturing, 8 of the 21 major U.S. industries (including mining) account for more
than 85% of all energy use.  These industries also tend to be energy-intensive, using large
amounts of energy per dollar of product output. Energy intensity is the single most important
indicator of energy efficiency in industry. The DOE Policy Office determined that more
efficient manufacturing delivered the largest component of total U.S. energy savings from 1970
to 1988 (Figure 5-7) (DOE 2003).

A brief overview of the eight major energy intensive U.S. industries follows, with links to
current industry-specific energy efficiency research and development.

Aluminum
The aluminum industry is responsible for approximately 2.8 percent of the total manufacturing
energy consumed in the United States and 1.6 percent of all U.S. electricity consumption.
Energy-intensive operations consist of the primary aluminum production from ore, secondary
aluminum production from scrap, shape casting, rolling, and extrusion (DOE 2005a). The
melting and thermal operations used in primary and secondary metal production provide large
opportunities for energy efficiency improvement.  More information on the aluminum
industry's energy efficiency vision, roadmap, and current energy efficiency research and
development projects can be found at: http://wwwl.eere.energv.gov/industry/aluminum/.

Chemicals

The U.S. chemical industry is the largest in the world. It converts raw materials (oil, natural
gas, air, water, metals, and minerals) into more than 70,000 different products. Chemicals are
used to make a wide variety of consumer goods, as well as thousands of inputs to agriculture,
manufacturing, construction, and  service industries. Major industrial customers include rubber
and plastic products, textiles, apparel,  petroleum refining, pulp and paper, and primary metals
(EIA 2009a).

While the U.S. chemical industry has significantly reduced energy consumption in the past
several decades, it still consumes  close to 25 percent of all manufacturing energy use (EIA
2009a). The chemicals industry is energy intensive because processes involve a series of
                                           5-83

reactions, followed by the separation of the desired product. Currently, most industrial
chemical reactions have low conversion and selectivities - and thus low product output. Higher
quantities of product require more reactions, which makes processes very energy- and capital-
intensive. Current R&D strategy in the chemical industry focuses heavily on improving
reaction conversion and selectivities, and investigating ways to improve the efficiency of
separation processes.

In 1996, chemical industry leaders articulated a long-term vision for the industry in the
Technology Vision 2020—The U.S. Chemical Industry.  This vision, along with the DOE
Industrial Technologies Program (ITP) roadmap, is used to guide energy efficiency research
(DOE 2009c). More information can be found at:
http ://wwwl. eere. energy, gov/industry/chemicals/index. html.

Forest Products

In the forest products industry, transforming whole trees into lumber and wood products or into
pulp and paper products requires physical and chemical processes that are often highly energy-
intensive. Pulp and paper mills account for the largest share of energy use in the industry,
mainly due to the amount of energy required to evaporate the large quantities of water used to
form the pulp slurry and the paper web. Although the industry self-generated close to 40% of
its energy needs by 1998, it is still the third largest user of fossil energy in the U.S.
manufacturing sector (DOE 2009g).

The forest products industry roadmap states that the industry will use emerging technologies,
such as biotechnology and nanotechnology, as well as advances in manufacturing process
technologies improve efficiency. The industry has focused research efforts into converting
existing mills into "biorefmeries" that are energy self-sufficient and produce biomass-derived
products—including traditional wood and paper products, wholesale electricity, fuels, and
chemicals—using manufacturing by-products, forest residues, and/or agriculture residues as
feedstock (DOE 2006).  More information on energy efficiency research and development in
the forest products industry can be found at:
http://wwwl.eere.energv.gov/industry/forest/index.html.

Glassmaking

Glass products are used in food and beverage packaging, lighting, communications,
transportation, and building construction. The four sectors of the glass industry - container, flat,
specialty, and fiberglass - produce over 20 million tons of glass annually. Glassmaking is a
relatively energy-intensive industry, primarily due to the large amount of energy required to melt
and refine glass. ITP is currently sponsoring cost-shared research and development of alternative
methods for melting and refining glass. In addition, some air emissions from glassmaking
processes are hazardous or toxic and must be controlled through energy-intensive incineration.

In January 1996, the glass industry published Glass: A Clear Vision for a Bright Future, which
articulated the industry's future vision, and in 2002 the industry and ITP published the Glass

Metal Casting

More than 90 percent of all manufactured goods and capital equipment use metal castings as
engineered components or rely on castings for their manufacture. The metal casting industry
produces both simple and complex components of numerous varieties. In addition to producing
components of larger products, foundries may also do machining, assembling, and coating of
the castings. As of 2009, there were nearly 3,000 metal casting foundries operating in all 50
states (EIA 2009b).  Major end-use applications for castings include power generation
equipment, defense systems and machinery, motor vehicles, transportation equipment, oil field
machinery, pipelines, industrial machinery, construction materials, and other products (DOE
2005c).

The basic metal casting process consists of pouring or injecting molten metal  into a mold or die
containing a cavity of the desired shape. The most commonly used method for small- and
medium-sized castings is green sand molding, accounting for approximately 60  percent of
castings produced. Other methods include die casting, shell molding, permanent molding,
investment casting, lost foam casting, and squeeze casting (DOE 2005c). The major energy-
consuming processes in the metal casting industry include melting of metal, coremaking,
moldmaking, heat treatment, and post-cast activities (DOE 2009J).

DOE and the metal casting industry have grouped energy efficiency research into three
categories:

      Advanced Melting: Research that establishes new melting practices, and/or new design
      methodologies to significantly improve the energy efficiency of melting and save costs for
      metal casters. Research in this area will improve melt efficiency, reduce metal transfer heat
      loss, reduce scrap/revert, and improve mold yield.

.     Innovative Casting: Research that advances energy-efficient casting processes and practices
      that will increase yield and reduce scrap. Research in this area is developing accurate
      simulation tools, the  ability to produce thin-wall, high-performance castings, real-time
      sensors and controls, improvements in rapid prototyping, and expanding the knowledge
      base of various material properties and performances.

      R&D Integration and System Analysis: Integration of applicable ITP technologies for
      improving energy efficiency and reducing emissions in metal  casting practices. This
      includes other ITP portfolios and ITP's Best Practices program for energy demand
      management (DOE 2005c).

industry, can be found at: http://wwwl.eere.energv.gov/industry/metalcasting/index.html.

Mining

Materials mined in the U.S. mining industry include:

•    Coal: defined as a combustible rock containing more than 50 percent by weight and more
     than 70 percent by value of carbon materials, including inherent moisture.

•    Metals: defined as opaque lustrous elemental substances that are good conductors of heat
     and electricity. Metals are also malleable and ductile, have high melting and boiling points,
     and tend to form positive ions and chemical compounds.

•    Industrial Minerals: defined as rocks and minerals not produced as sources of metals.
     Industrial minerals include stone, sand and gravel (DOE 2005d).

Surface and underground mining are the two extraction methods used by the mining industry.
The method selected depends on a variety of factors, including the nature and location of the
deposit, as well as the size, depth and grade of the minerals. Both surface and underground
mining are used widely in the extraction of coal. Most of the  industrial minerals in the United
States are  extracted by surface mining.

Energy-intensive processes in the mining industry include materials handling, ore crushing and
separation, processing, and extraction.  Energy requirements  include electricity for ventilation
systems, water pumping, and crushing and grinding  operations. Diesel fuel is used for hauling
and other transportation needs.

Several analytical studies provide the basis for energy efficiency research and development
decision making in the mining industry's partnership with DOE, including the 1999
Crosscutting Technologies Roadmap, the 2000 Mineral Processing Technologies Roadmap,
and the 2002 Exploration and Mining Technologies  Roadmap.  In addition, the DOE Industry
of the Future vision, Energy and Environmental Profile, Bandwidth and Energy Footprint
studies have focused R&D efforts.  These studies were developed using both government and
industry data and information, and are available at the DOE website:
http://wwwl.eere.energy.gov/industry/mining/index.html.

In 2003, a mining industry energy  analysis was completed in partnership with DOE. This
analysis demonstrated that the largest opportunities for energy savings in mining were materials
handling, beneficiation and processing, and extraction. Diesel technologies consumed the
highest amount of energy in materials handling, accounting for 87 percent of the energy used.
Comminution activities - or crushing and grinding - were the largest energy consumers in
beneficiation and processing, accounting for 75 percent of the energy used. Finally, pumping
consumed the most energy in extraction, accounting for 41 percent. Although materials
handling, and beneficiation and processing consume the largest amount of energy,
improvements in extraction could reduce downstream  materials handling and processing,
reducing energy needs (DOE 2005d). More information on the energy analysis can be found at:

Petroleum Refining

Petroleum refining is the largest industrial user of energy in the United States. It is both the
country's single largest source of energy products, supplying 39% of total U.S. energy demand
and 97% of transportation fuels, and the largest industrial consumer, representing about 7.5
percent of total U.S. energy consumption (DOE 20091). The U.S. uses two times more
petroleum than either coal or natural gas and four times more than nuclear power or renewable
energy sources.

Before petroleum can be used, it is sent to a refinery where it is physically, thermally, and
chemically separated into fractions and then converted into finished products. About 90 percent
of these products are fuels such as gasoline, aviation fuels, distillate and residual oil, liquefied
petroleum gas (LPG), coke, and kerosene. Refineries also produce non-fuel products, including
petrochemicals, asphalt, road oil, lubricants, solvents, and wax. Petrochemicals (ethylene,
propylene, benzene, and others) are shipped to chemical plants, where they are used to
manufacture chemicals and plastics (EIA 2009c). The United States has nearly 150 refineries
that can process anywhere between 5,000 and 500,000 barrels of oil per day.

Although the industry relies heavily on refining process by-products as energy sources, energy
expenditures  still represent a significant portion of manufacturing costs for petroleum refiners.
The DOE Petroleum Refining Industries of the Future program is currently not funding any
active projects and has no solicitations planned for the near future. ITP funding has been
redirected to areas that are less inclined to attract private investment without federal leadership.
However, as a former participant in the program, the U.S. petroleum refining industry set a
vision and roadmap to define its R&D priorities, and developed a portfolio of energy efficiency
related projects.  Currently, the  petroleum refining industry is pursuing its own R&D portfolio.
Many of the collaborative R&D projects completed through its Industry of the Future
partnership continue to yield benefits to the industry. In addition, many of the publications, tip
sheets, software tools, and other resources developed through the partnership are in active use at
U.S. refineries (DOE 20091).  More information can be found at:
http ://wwwl. eere. energy. gov/industry/petroleum_refming/index. html.

Steel

The steel industry accounts for 2-3% of total U.S. energy consumption. Steel is produced via
two different routes, both of which are energy-intensive: using blast furnaces or electric arc
furnaces. Integrated or blast furnace facilities are ore-based, and electric arc furnace facilities
are primarily scrap-based. Ohio, Indiana, Pennsylvania, Illinois, and Michigan have the highest
concentration of steel industry facilities (EIA 2009d).  About half of steel industry facilities
currently conduct energy-management activities (DOE 2009n).

The U.S. iron and steel industry relies heavily on coal and natural gas for fuel. In  1998 the
industry used approximately 7% of all U.S. manufacturing energy use and 2% of domestic
energy use. The industry has made significant improvements in energy efficiency, reducing
energy use per unit of output by over 45% since 1975.  Additionally, steel is now the most
recycled material in North America, with an overall recycling rate of 67% (DOE 2009n).

                                          Energy Efficiency Reference for Environmental Reviewers
The steel industry has created a vision and roadmap for energy efficiency research and
development, in partnership with DOE. Technologies that improve the efficiency of furnaces
and other process heating systems have significant potential to reduce overall steel industry
energy use.  The three major R&D focus areas are:

•    Cokeless Ironmaking
•    Next Generation Steelmaking
•    Advanced Process Development

related publications, can be found at: http://wwwl.eere.energv.gov/industry/steel/index.html.

5.8.b Related Federal Partnership Programs

Industrial Technologies Program (ITP)

The DOE Industrial Technologies Program (ITP) supports public/private partnerships to
improve industrial energy efficiency and environmental performance. The program has four
major elements:  Energy Intensive Industries R&D, Crosscutting Technologies R&D, Best
Practices, and Industrial Assessment Centers.

Energy Intensive Industries

Energy Intensive Industries supports research partnerships to reduce energy consumption for
the country's most energy-intensive industries: aluminum, chemicals, forest products, glass,
metal casting, mining, petroleum refining, and steel.  These industries participate in the DOE
Industries of the Future process, which helps an entire industry articulate its long-term goals
and publish them in a unified vision for the future. To achieve that vision, industry leaders
jointly define detailed R&D agendas known as roadmaps. Roadmaps are used to identify
opportunities for industry collaboration and to guide Federal R&D spending.  ITP relies on
roadmap-defmed priorities to target cost-shared solicitations and guide development of an R&D
portfolio that yields results in the near-, mid-, and long-term.

As part of the Energy Intensive Industries area, ITP regularly conducts energy analyses for each
of the eight Industries of the Future to identify energy savings opportunities. These analyses
include Energy and Environmental Profiles, as well as Energy Footprints, for each industry.
Energy Footprints map the flow of energy supply, demand, and losses in U.S. manufacturing
industries. Identifying the sources and end uses of energy helps to pinpoint areas of energy-
saving opportunities, and provides a baseline to calculate the benefits of improving energy
efficiency. Although actual energy use in a plant will vary, each footprint represents an average
picture  of energy use for each industry and illustrates:

•    The portion of energy that is purchased from utilities, generated onsite, and transported to
     the local grid.
     Where and how energy is used within a typical plant.

•    Where energy is lost due to inefficiencies, both inside and outside the plant.  Energy losses
     shown on the footprints indicate immediate opportunities to improve efficiency and lower
     energy consumption by implementing best energy management practices, improved energy
     systems, and new technology. Links to the energy analyses pages for each industry are:

Crosscutting Technologies

 IIP conducts R&D to improve efficiency of technologies that are common to many industrial
processes and can benefit multiple industries. Because of the widespread application of these
crosscutting systems, even small improvements in their efficiency can yield large energy savings.
In addition to research, ITP provides cost-shared funding for related projects identified as
priorities by specific industries. DOE is currently conducting research on the following
crosscutting technologies:

Combustion.  U.S. industries rely on combustion systems for heat and steam generation.
Combustion systems account for nearly three-quarters of all energy used in U.S. manufacturing.
Combustion components and systems offer opportunities for significant energy and emissions
savings in almost every industry (Figure 5-8) (DOE 2009d).

Manufacturers and users of burners, boilers, furnaces, and other process heating equipment
partnered with DOE to create a vision and roadmap for improving the energy efficiency of
combustion technology, and many subsequent demonstration projects have achieved substantial
energy savings. More information on these projects can be found at:
http ://wwwl. eere. energy. gov/industry/combusti on/index.html.

Distributed Energy

Combined Heat and Power (CHP) involves the sequential process of producing and utilizing
electricity and thermal energy from a single fuel. CHP is widely recognized to  save energy and
costs, while reducing carbon dioxide and other pollutants. CHP is a realistic, near-term option for
large energy efficiency improvements and significant CC>2 reductions.

While CHP is a well-established practice in large industrial processes with sizable electricity  and
thermal loads, DOE analyses indicate a largely untapped potential exists for applications less
than 50 megawatts in electrical demand. Increased CHP deployment could help contribute to  a
25% reduction in U.S. industrial energy intensity by 2017 and an  18% reduction in U.S. carbon
intensity by 2012 (DOE 2009e).

CHP technology uses several distinct names (e.g., cogeneration, Combined Cooling, Heating and
Power (CCHP), Building Combined Heat and Power (BCHP), Distributed Energy Resources
(DER),  and Integrated Energy Systems (IES)). CHP and cogeneration are basically the same
thing, although cogeneration has been identified with district heating and large utility owned
power plants or industrial power production and plant operation. CHP is generally a smaller
scale, privately owned operation. CCHP stresses that combined cooling, heating, and power
production  occur, whereas combined heating and power in CHP may or may not use the
recovered heat for cooling purposes. BCHP is just CHP applied to a building as opposed to a
district heating system or industrial process. DER is distributed energy resources, the use of
small  generating facilities distributed close to the consumers either with or without heat
recovery. IES is an integrated energy system that recovers waste heat from on-site or near-site
power generation to provide hot water, steam, heating, cooling, or dehumidifying air for
buildings (DOE 2009e).

DOE provides support for conducting CHP market assessments, including market analyses of
CHP potential in supermarkets, restaurants, health care facilities, industrial sites, hotels and
motels,  and new commercial and institutional buildings and facilities used for infrastructure
resiliency.  Many of these assessments have led to the installation of CHP components and
systems in hospitals, schools, university campuses, commercial and industrial sites, and at
military installations, wastewater treatment facilities, office buildings, and farms.

The Oak Ridge National Laboratory 2008 report on CHP, Combined Heat and Power: Effective
Energy  Solutions for a Sustainable Future, summarizes the latest technological advances. The
report and more information on CHP can be found at:

This crosscutting research area focuses on the four top energy consuming technology platforms:
industrial reactions and separation, high-temperature processing, waste heat minimization and
recovery, and sustainable manufacturing. Figure 5-9 shows the four technology platforms and

Focus areas for industrial reactions and separations include advanced water removal, gas
separations, hybrid distillation, and energy-intensive conversions. High-temperature processing
focuses on the development of new materials, material processing, and process monitoring
technologies that increase energy efficiency during high-temperature processing. Waste heat
minimization and recovery reduces fuel demands of steam boilers and furnaces by utilizing
waste heat recovery. Sustainable manufacturing advances materials and technologies to improve
yields per unit energy cost for multiple elements of the manufacturing chain.  More information

Fuel and Feedstock Flexibility

U.S. industry is principally dependent on natural gas as a single major source of fuel or
feedstock. ITP's Fuel and Feedstock Flexibility subprogram focuses on various methods to
reduce natural gas use in industrial applications, including research to develop fuel flexible
hardware, and demonstration of fuel flexible technologies. IIP aims to accelerate the market
adoption of emerging technology options for industry, such as the utilization of gasified fuels,
landfill gas, and electro-technologies (DOE 2009h). More information can be found at:
http://wwwl.eere.energy.gov/industry/fuelflexibility/index.html.

Industrial Materials for the Future

New and advanced materials are key crosscutting technologies necessary for efficiency
improvements in processes using furnaces, boilers, gasifiers, steam systems, recuperators and
heat exchangers. This IIP activity conducts R&D to develop and test new advanced industrial
materials and material processing methods.

Material properties play a central role in determining the operating parameters and efficiencies of
almost all industrial processes. However, materials also cause many planned and unplanned
process interruptions in which productivity and energy are lost, and safety is compromised.
Operating efficiency  is also lost as materials corrode, wear, foul or otherwise degrade. Improved
materials that perform better under corrosive, high-temperature and high-pressure conditions will
enable new technologies to save more energy. In addition, longer lifetime saves the energy and
raw materials needed to produce and install replacement materials (DOE 2005b).  Detailed
information on technological developments in industrial materials can be found at:
http ://wwwl. eere. energy, gov/industry/imf/index. html.

Nanomanufacturing

Nanotechnology is the purposeful engineering of matter at the nano-scale, which ranges from 1
to 100 nanometers. A typical human hair is around 80,000 nanometers wide (DOE 2008).
Nanomanufacturing is the cost-competitive, large-scale production of uniform nanomaterials and
the integration of these nanomaterials in intermediate and finished products while maintaining
their unique properties. Nanotechnology can improve the energy efficiency and specificity of
chemical reactions, thereby increasing productivity. It can produce new and improved materials
(e.g., lighter, stronger, harder, more ductile, and high-temperature resistant) that provide superior
life-cycle benefits.  Initial R&D efforts are focusing on:

     Nanocoatings and thin-films for heat, wear, corrosion, and scratch resistance;
•    Nanocatalysts for applications in chemical, petroleum, pulp and paper, and energy
     production;
     Membranes and sorbents for more energy-efficient industrial separations; and
     Nanocomposites for industrial and automotive applications (DOE 2009k).

Sensors and automation

Sensor and automation technologies are vital, yet often unseen, components of virtually every
industrial process. Acting as part of a plant's "nervous system," these technologies - along with

Best Practices

The Best Practices program area implements and disseminates best practices in energy
management.  The program provides technical assistance to help industries identify energy
savings opportunities in manufacturing plants. Best Practices offers a range of software tools
and databases for plant  self-assessment of steam, compressed air, motor, and process heating
systems. The Quick Energy Profiler is an  online software tool that helps industrial plant
personnel quickly diagnose how energy is being used at their plant and find the largest
opportunities to save energy and money.  The Integrated Tool Suite is another software tool to
help plants find the best opportunities to reduce energy use in major energy-consuming systems
(DOE 2009b). Other software tools offered by Best Practices include:

Industrial Assessment Centers

The Industrial Assessment Centers program enables eligible small and medium-sized
manufacturers to have comprehensive industrial assessments performed at no cost to the
manufacturer. These assessments examine an industrial plant's site, its facilities, services and
manufacturing operations to identify energy efficiency improvements, waste minimization and
pollution prevention, and productivity improvement. Assessments are performed by local teams
of engineering faculty and students from the centers, which are located at 26 universities around
the country (DOE 2009i). More information can be found at:
http ://wwwl. eere. energy, gov/industry/bestpractices/iacs.html.

EPA Sector Notebooks

The Sector Notebook series is a unique set of profiles containing information for specific
industries and governments. Unlike other resource materials, which are organized by air, water,
and land pollutants, the Notebooks provide a holistic approach by integrating processes,
applicable regulations and other relevant environmental information. There are 33 Industry
Sector Notebooks and 3 Government Series that provide government officials with information
they need to comply with the environmental regulations that apply to their activities. Many of
them may provide useful information for the NEPA reviewer.  More information about the
Sector Notebooks can be found in the  Sector Notebook Factsheet located at:
http://www.epa.gov/compliance/resources/publications/assistance/sectors/notebooks/sector-
notebooks-factsheet.pdf. The notebooks can be accessed at:

5.8.c Review Considerations

309 Reviewers should identify whether energy efficiency requirements are addressed in EISs.  It
is understood that rather than repeating a lengthy discussion on these requirements, the EISs will
most likely incorporate them by  reference by citing the appropriate document. Many times these
documents are made available via a link to a web site in the EIS. In most cases, this should
suffice.

For federal actions related to industrial facilities, Reviewers  should encourage federal agencies to
comply with Energy Policy Act of 2005 and E.O. 13423-Strengthening Federal Environmental,
Energy, and Transportation Management as appropriate. The Act requires annual two percent
reductions in energy use at federal agency buildings (including industrial and laboratory
facilities) through 2015, with DOE to complete a review of the government's performance in
response to this requirement by the end of 2014 and recommend additional measures for 2016
through 2025. E.O.  13423 strengthens this requirement by 50% to compel the reduction of
greenhouse gas  emissions by three percent annually by 2015 or by 30 percent by the end of 2015
(using 2003 as the baseline).  Existing facilities should provide documentation of their annual
energy reduction, and new facilities should include a plan for meeting the federal requirement.

The Act also promotes the use of voluntary agreements between industrial energy users and
federal agencies to reduce energy intensity (defined as  "the primary energy consumed for each


                                          5-94                EPA Publication No. 315-R-09-001

                                          Energy Efficiency Reference for Environmental Reviewers
unit of physical output in an industrial process" (P.L. 109-58, Sec. 106(a)). The agreements are
to have as a goal the reduction of energy intensity by at least 2.5 percent each year from 2007
through 2016. Existing and new facilities should consider entering a voluntary agreement to
reduce energy efficiency, which includes eligibility for grants and technical assistance.

For new industrial facilities, energy efficient facility siting, construction, and building design
should be documented within the EIS. These topics are covered in Sections 5.2, 5.3 and 5.4,
including federal energy efficiency requirements for buildings. Section 5.4 also discusses energy
efficiency associated with water use, often a substantial factor in an industrial facility's energy
use. Section  5.9, Federal Vehicle Fleets, may also have relevant information for industrial
facilities that transport raw materials into, and dispose of waste outside the facility. Minimizing
transportation energy use is another significant factor in an industrial facility's overall energy
use.

For operation of industrial facilities, opportunities exist to reduce energy use in both process-
specific operations and cross-cutting energy systems. As discussed above, DOE provides
extensive information on improving energy efficiency for the eight most energy-intensive U.S.
industries: aluminum, chemicals, forest products, glass, metal casting, mining, petroleum
refining, and  steel. Many of the technological advances in the links provided above are market
ready and/or  already in use. Reviewers should encourage facilities to incorporate industry-
specific advanced technology as feasible and practicable.

In addition, the DOE ITP has identified combustion, distributed energy, energy intensive
processes, fuel and feedstock flexibility, industrial materials of the future,  nanomanufacturing,
sensors and automation as cross-cutting technologies that improve energy  efficiency across
industries.  Reviewers may want to ask whether the industrial facility has utilized appropriate
ITP software tools described above to identify energy savings opportunities.

Reviewers may want to become familiar with the Bonneville Power Administration's Industrial
Audit Guidebook: http://www.bpa.gOv/energy/n/Projects/industrial/pdf/audit guide.pdf  The
guidebook was created for performing walk through energy audits of industrial facilities.  Its
purpose is to  introduce the user, both technical and non-technical, to common opportunities that
may be found in an industrial facility to reduce electrical energy consumption. Topics include:

     Lighting Systems                            •   Material Handling Systems
     Motors, Belts and Drives                     •   Hydraulic Systems
     Fans and Pumps                             •   Injection Molding or Extrusion
     Compressed  Air systems                     •   Veneer Dryers
     Steam Systems                              •   Kiln Drying
     Refrigeration Systems                       •   Energy Management

Each topic has a series of questions about the efficiency level of the specific system, as well as
general notes and useful tips on each topic.

5.9 Federal Vehicle Fleets

5.9.a Summary

The federal vehicle fleet consists of more than 650,000 vehicles, approximately 20 percent of
which are alternative fuel vehicles (AFVs) (FEMP 2009). Technological advances in
transportation equipment, vehicle design, and alternative fuels offer significant energy efficiency
improvements that can be applied to federal vehicle fleets.

Vehicles are categorized and regulated based on weight. Federal agencies acquire light-duty
vehicles, medium-duty vehicles and heavy-duty vehicles.  Typically medium-duty vehicles are a
subset of heavy-duty vehicles. Federal agencies are subject to vehicle acquisition requirements
that define the light-duty vehicles and medium-duty passenger vehicles they can acquire, and
fuel use requirements.

EPAct 1992, as amended by EISA, requires that federal agencies acquire low GHG-emitting
light-duty and medium duty passenger vehicles and alternative fuel vehicles as 75% of their
light-duty vehicle acquisitions. The requirement to purchase only low GHG-emitting vehicles
applies to all vehicle acquisitions. The AFV requirement applies to fleets. The Energy Policy
Act of 2005 requires that AFVs only be operated with alternative fuel. Agencies must receive a
fuel waiver from DOE to operate an AFV with gasoline. Executive Order 13423 and section 142
of EPAct 1992 require that federal agencies increase their alternative fuel consumption 10%
from the previous year, reduce their petroleum consumption 2% per year, and acquire plug-in
hybrid electric vehicles when commercially available. Section 246 of EISA, requires that federal
agencies install  renewable fuel  pumps at all fleet refueling centers.

Under EISA 2007 section 141,  EPA is required to provide guidance to federal  fleets for the
acquisition of low GHG-emitting vehicles.  EPA's definition of a low GHG-emitting vehicle is
technology and  fuel neutral. All vehicles are weighted equally.  EPA believes the acquisition of
low GHG-emitting vehicles will expedite achievement of an agency's petroleum consumption
reduction requirement and reduce an agency's GHG emissions.

EO 13514 establishes a percentage reduction target for agency-wide reductions of GHG
emissions in absolute terms by  fiscal year 2020.  In establishing the target, each agency shall
consider reducing the use of fossil fuels by:
    •   using low greenhouse gas emitting vehicles including alternative fuel vehicles;
    •   optimizing the number of vehicles in the agency fleet; and
    •   reducing, if the agency operates a fleet of at least 20 motor vehicles, the agency fleet's
       total consumption of petroleum products by a minimum of 2 percent annually through the
       end of fiscal year 2020, relative to a baseline of fiscal year  2005.

In fiscal year 2005, U.S.  government spent approximately $708.2 million for gasoline, $377.2
million for diesel fuel, and $0.6 million for propane to operate governmental surface vehicles.
Utilizing advanced fuel and vehicle technology to gradually improve the  energy efficiency of
federal fleets can reduce energy consumption and costs for fuels.

                                         Energy Efficiency Reference for Environmental Reviewers
Light duty vehicles (passenger cars, sport utility vehicles, vans and pick-up trucks with a gross
vehicle weight of less than 8,500 pounds) consume approximately 40% of all U.S. oil
consumption. These same vehicles account for approximately 20% of total U.S. emissions of
carbon dioxide (US EPA 2008).

Since 1975, nationwide fuel efficiency has seen four basic trends: a rapid increase from 1975
through the early 1980s as a reaction to the oil shortages of the 1970s; a slower increase until
reaching peak fuel efficiency in 1987; a gradual decline from  1987 to 2004 (the year in which the
U.S. had the lowest fuel economy standard since 1980), and a steady increase beginning in 2005
(US EPA 2008).

For model year 2008, passenger cars are projected to average 24.1 mpg and light trucks are
estimated to average 18.1  mpg - representing a fleet wide light-duty fuel economy adjusted
average of 20.8 mpg. Since 2004, light truck fuel economy has increased 1.4 mpg, while car fuel
economy has increased by 1.0 mpg. Overall fuel efficiency has increased approximately 1.8%
since 2004, from 19.3 mpg to 20.8 mpg. Changes in vehicle weight and advanced transmission
and engine design, along with increases in use of front-wheel drive, variable valve timing and
cylinder deactivation, have all contributed to a general increase in fuel  efficiency since 2004 (US
EPA 2008).

Fleet-wide fuel  economy standards are required under the Energy Policy Act of 1975.  The
National Highway Traffic Safety Administration (NHTSA), in cooperation with EPA,
promulgates such standards and implements the Corporate Average Fuel Economy (CAFE)
program. CAFE is the sales weighted average fuel economy, expressed in miles per gallon
(mpg), of a manufacturer's fleet of passenger cars or light trucks with a gross vehicle weight
rating (GVWR) of 8,500 Ibs. or less, manufactured for sale in the United States, for any given
model year. A passenger car CAFE standard of 27.5 mpg has been in effect since model year
1990. Light-duty truck CAFE standards have recently evolved from a standard of 21.0 mpg for
model year 2005, to 21.6 mpg for model year 2006, to 22.2 mpg for model year 2007, and to
22.5 mpg for model year 2008 (US EPA 2008).

EPA and DOT are working together on light-duty vehicle GHG/fuel economy standards that will
increase average fuel economy and establish, for the first time, a GHG-emission standard for
passenger vehicles. Under EISA 2007, a CAFE goal has been set of 35 mpg for 2020 - a fuel
economy increase of 40%. To reach this goal, manufacture of fuel-efficient vehicles will need to
increase substantially.

Alternative Fuels

Biodiesel

Biodiesel is a clean-burning, renewable substitute for petroleum diesel. Biodiesel is a liquid fuel
made up of fatty acid alkyl esters, fatty  acid methyl esters (FAME), or long-chain mono alkyl
esters. It is produced from renewable sources such as new and used vegetable oils and animal
fats and is a cleaner-burning replacement for petroleum-based diesel fuel. It is nontoxic and
biodegradable. Biodiesel can be produced domestically and used in conventional diesel engines,


                                         5-100               EPA Publication No. 315-R-09-001

                                          Energy Efficiency Reference for Environmental Reviewers
directly substituting for or extending supplies of traditional petroleum diesel. It also has an
excellent energy balance: biodiesel contains 3.2 times the amount of energy it takes to produce it
(DOE 2009a). Compared with using petroleum diesel, using biodiesel in a conventional diesel
engine substantially reduces emissions of unburned hydrocarbons (HC), carbon monoxide (CO),
sulfates, polycyclic aromatic hydrocarbons, nitrated polycyclic aromatic hydrocarbons, and
particulate matter (PM). The reductions increase as the amount of biodiesel blended into diesel
fuel increases. Using biodiesel also reduces greenhouse gas emissions because carbon dioxide
released from biodiesel combustion is offset by the carbon dioxide sequestered while growing
the soybeans or other feedstock. Biodiesel is  nontoxic, so it causes far less damage than
petroleum diesel if spilled or otherwise released to the environment. It is also safer than
petroleum diesel because it is less combustible (DOE 2009a).  There are uncertainties over the
average effect the use of biodiesel has on NOx emissions. Some studies have shown  an increase
in NOx emissions with biodiesel use, but insufficient data exists for a definite conclusion (NREL
2005).

Biodiesel production in the U.S. has risen dramatically since 2001 (Table 5-6). Concurrently, the
number of biodiesel fueling stations has risen from 16 in year 2001 to approximately  645 in
2008. As a direct replacement for conventional petroleum based diesel, biodiesel has  the
potential to have a dramatic impact on a reduction in the  dependency on foreign oil sources, as
well as some environmental benefits (DOE 2009a).

Electricity

Electricity can be used to power electric and plug-in hybrid electric vehicles (EVs). EVs store
electricity in an energy storage device, such as a battery. The electricity powers the vehicle's
wheels via an electric motor. The only emissions that can be attributed to electricity as a vehicle
fuel are those generated in the electricity production process. Home recharging of EVs is as
simple as plugging them into an electric outlet. Electricity fueling costs for electric vehicles are
reasonable compared to gasoline, especially if consumers take advantage of off-peak rates.
However, electricity costs vary across the U.S. depending on location, type of generation, and
time of use.  Additionally, EVs have limited energy storage capacity, which must be replenished
by plugging into an electrical source (DOE 2009b).

Use of electricity as a transportation fuel has some environmental and operation drawbacks.
While electric vehicles themselves may not produce carbon-based emissions, increased electric
generation and its inherent emissions would be needed to supply the fuel. Electric batteries used
to store energy in a vehicle must be manufactured and will ultimately need to be disposed, and
these batteries often contain high levels of toxic materials which poses a disposal issue. When a
federal agency is acquiring electric vehicles, it should consider two key factors: the Ev's rate of
energy consumption, typically measured in kWh/mi, and the emissions from the generation of
the electricity that is used to charge the Ev's batteries.

Use of electricity as a transportation fuel has increased from approximately 1 million gasoline
gallon equivalents  in 1997 to about 5.1 million gasoline gallon equivalents, with a peak usage of
7.3 million gasoline gallon equivalents in 2002. Electric fueling stations have increased from 188
in 1995 to around 430 today. While this is a reduction in available stations since the early 2000s,
much of this reduction is due to an increase in travel range from technological advancements in
battery performance (DOE 2009b).

Ethcmol

Ethanol, also known as ethyl alcohol, grain alcohol, is a clear, colorless liquid that can be
produced from various plant materials, which collectively are called "biomass." Today, nearly
half of U.S. gasoline contains ethanol in a low-level blend to oxygenate the fuel and reduce air
pollution. E85, which is typically 83% ethanol, is increasingly becoming available and is an
alternative fuel that can be used in "flexible fuel" vehicles. Studies have estimated that ethanol
and other biofuels could replace 30% or more of U.S. gasoline demand by 2030. Biomass for
ethanol production can be generated from starch and sugar based plants (such as corn or sugar
cane) or from cellulosic feedstocks which include certain types of grass or woody plants or crop
or wood residues. Ethanol is derived from feedstocks primarily via fermentation. Cellulosic
feedstocks are also increasingly being converted to ethanol using heat and chemicals in a process
called thermochemical conversion. Today, most ethanol in the U.S. is derived from corn grain,
which has experienced increased production and substantial use in ethanol over the last several
years (DOE 2009c).

Ethanol is a high-octane fuel, which increases  engine performance. Low-level blends of ethanol,
such as E10 (10% ethanol, 90% gasoline), generally have a higher octane rating than unleaded
gasoline. Low-octane gasoline can be blended with 10% ethanol to attain the standard 87 octane
requirement. Ethanol is the main component in E85, a high-level blend of 83% ethanol and
gasoline. Ethanol is a renewable, largely domestic transportation fuel which helps reduce
imported oil dependence and greenhouse gas emissions. The carbon dioxide released when
ethanol is burned is balanced by the carbon dioxide captured when the crops are grown to make
ethanol. According to Argonne National Laboratory, on a life-cycle analysis basis, corn-based
ethanol production and use reduces greenhouse gas emissions (GHGs) by up to 52% compared to
gasoline production and use (DOE 2009c).

Ethanol use and  availability has increased significantly since around 2004 (Table 5-7 and 5-8).
Domestic consumption of ethanol has increased 445% between 1997 and 2007. In 1997, E85

ethanol fuel was available at 71 fueling stations in the U.S. mostly confined to the midwest. In
2008, E85 fuel was available at 1,644 stations across the country (DOE 2009c).

  Notes:
  [1] Negative numbers indicate decrease, assumed to be zero for years where values not given.
  2007 numbers are preliminary.
  Ethanol consumption values are close to, but sometimes less than the EIA aggregates of
  ethanol used in blends + ethanol used in E85.

Environmental issues with ethanol center around several potential problems. First, pure ethanol
has less energy by volume, about 34% less energy, than conventional gasoline, meaning that
overall more ethanol is needed than conventional gasoline. Secondly, increased use of cropland
to support ethanol production would increase water consumption for irrigation, decrease land
available for food stocks and potentially raise food production costs worldwide. Finally,
increased ethanol production has resulted in increased conversion of rainforest to agriculture.
Therefore, much effort and research is being devoted to use of cellulosic feedstocks (DOE
2009c).

Hydrogen

The interest in hydrogen as an alternative transportation fuel stems from its clean-burning
qualities, its potential for domestic production,  and the fuel cell vehicle's potential for high
efficiency (two to three times more efficient than gasoline vehicles). Currently, steam reforming
of methane (natural gas) accounts for about 95% of the hydrogen produced in the United States.
Hydrogen can be produced domestically from resources such as natural gas, coal, solar energy,
wind, biomass, and nuclear energy, with the potential for near-zero greenhouse gas emissions.
Because the transportation sector accounts for about one third of U.S. carbon dioxide emissions,
which contribute to climate change, using these sources to produce hydrogen for transportation
can slash greenhouse gas emissions. Once produced, hydrogen generates power without exhaust
emissions in fuel cells. It holds promise for economic growth in both the stationary and
transportation energy sectors (DOE 2009d).

Utilization of hydrogen in alternative fuel vehicles has increased from essentially zero to 41,000
gasoline gallon equivalents in 2006 (DOE 2009d). According to the National Hydrogen
Association, hydrogen fuel is currently available at 61 fuel stations in the U.S., with
approximately 45% of those sites in California  (NHA 2009). A national network of 284
hydrogen refueling stations is proposed to be in place by 2018 when hydrogen vehicles are
projected to be commercially  available in the U.S. in substantial numbers (NREL 2006).

Natural Gas

Natural gas is a domestically available, inherently clean-burning fuel, mostly extracted from gas
and oil wells. Natural gas has a high octane rating and excellent properties for spark-ignited
internal combustion engines. It is non-toxic, non-corrosive, and non-carcinogenic. It generally
presents a reduced threat to soil, surface water,  or groundwater in comparison to traditional fuel
sources, although methane emissions from gas drilling have been associated with contaminated
groundwater, drinking water and methane releases inside buildings and homes. Natural gas
accounts for approximately one quarter of the energy used in the United States. Of this, about
one third goes to residential and commercial uses, one third to industrial uses, and one third to
                                          5-104                EPA Publication No. 315-R-09-001

                                                                             March 2010
                                          Energy Efficiency Reference for Environmental Reviewers
electric power production. Only about one tenth of one percent is currently used for
transportation fuel (DOE 2009e).

Natural gas vehicle and infrastructure development can facilitate the transition to hydrogen-fuel
cell technology. With the highest hydrogen-to-carbon ratio of any energy source, natural gas is
an efficient source of hydrogen—in fact, it is the number one source of commercial hydrogen
used in the United States. The vast U.S. network of natural gas transmission lines offers the
potential for convenient transportation of natural gas to future refueling stations that reform
hydrogen from the gas (DOE 2009e).

Natural gas, as either compressed natural gas (CNG) or liquefied natural gas (LNG) is the second
most utilized alternative fuel today, behind only liquefied petroleum gas (LPG). Together, CNG
and LNG have increased in utilization by 1,000 %, from  17,575,000 gasoline gallon equivalents
in 1992 to 195,485,000 gasoline gallon equivalents in 2006.  CNG is the most popular form of
natural gas fuel, available at over 750 fueling stations across the country (DOE 2009e).
Historically, LNG has been less utilized in the United States; between 1% and 3% of U.S.
demand for natural gas was met by LNG from 2004-2009. However, U.S. LNG import capacity
is expanding and is expected to be more than six times greater in 2009 than it was at the
beginning of the decade.  Growth in LNG imports remains uneven, due to a high sensitivity to
the volatile prices of the natural gas market (EIA 2009).

Propane

Propane, or liquefied petroleum gas (LPG), is the most prevalent alternative transportation fuel
in use today.  Propane is produced as a by-product of natural  gas processing and crude oil
refining and accounts for about 2% of the energy used in the United States. Propane vehicle
technology is well established, and propane fueling stations are widely distributed with more
than 2,000 locations  in the U.S. Propane has one of the highest energy densities of all alternative
fuels, so propane vehicles go farther on a tank of fuel in comparison to gasoline vehicles. It is
also an exceptionally safe fuel, as propane tanks are 20 times more puncture resistant than
gasoline tanks, and propane has the lowest flammability range of all alternative fuels. LPG's
generally have cleaner combustion properties. Propane engines can be calibrated to chose
between pollutants, making the engine additionally useful in achieving pollution-reduction
targets. A rich calibration reduces NOX at the expense of increasing CO and non-methane
hydrocarbons and a lean calibration does just the opposite (DOE 2009f).

Ultra-low sulfur diesel

Ultra-low sulfur diesel (ULSD) is classified as diesel fuel containing 15 parts per million (ppm)
or less in sulfur content. Most highway diesel fuel meets this requirement and it is mandated for
all diesel sold in the U.S. by 2010. Previously, typical highway diesel fuel contained up to 500
ppm of sulfur. Use of ULSD in light-heavy duty vehicles enables the use of catalytic converters
and paniculate traps  routinely used in gasoline vehicles. These components help to reduce
emissions of nitrogen oxides (NOX) and particulate matter (PM), issues which were particularly
troublesome with previous diesel engine applications using standard diesel fuel. Additionally,
since diesel engines are typically 20-40% more efficient than comparable gasoline engines,
                                          5-105                EPA Publication No. 315-R-09-001

                                          Energy Efficiency Reference for Environmental Reviewers
increased use of ULSD (especially sources produced from non-petroleum and renewable
resources) will reduce dependence on foreign petroleum sources and may reduce emission of
greenhouse gases (DOE 2009g).

Passenger Vehicles

For all types of passenger vehicles, energy efficiency can be improved through proper
maintenance.  Improperly inflated tires and poor wheel alignment adversely affect fuel
efficiency.  Under-inflated tires increase the tires' rolling resistance, and increased rolling
resistance requires more fuel to move the vehicle.

As the U.S. moves toward the increased use of alternative fuels, vehicle applications continue to
mature. Since 1995, alternative fuel vehicles (not counting hybrid vehicles) in use in the U.S
have increased from 246,855 to 634,559 in year 2006. In fiscal year 2008, federal agencies
acquired 27,925 alternative fuel vehicles. Greater than 99% of these acquisitions were flexible
fuel vehicles capable of operating with E85.  Electric/battery powered vehicles use the energy
stored in a battery (or series of batteries) for vehicle propulsion, resulting in vehicles with fast
acceleration but limited distance before recharge. Combustion-based and electrochemical
hydrogen vehicles are emerging along with compressed natural gas; both becoming viable fuel
energy alternatives. Vehicle technology is quickly emerging, and will be highly impacted by
consumer preferences, costs, and the availability of support infrastructure.

Electric

In an  electric vehicle (EV), a battery or other energy storage device is used to store the electricity
that powers the motor. EV batteries must be replenished by plugging in the vehicle to a power
source. Some electric vehicles have onboard chargers; others plug into a charger located outside
the vehicle. Both types, however, use electricity that comes from the power grid. Although
electricity production may contribute to air pollution, EVs are considered zero-emission vehicles
because their motors produce no exhaust or emissions. No purely electric vehicles are currently
available from the major automotive manufactures (DOE 2009h).

Natural Gas

Dedicated natural gas vehicles (NGVs) are designed to run only on natural gas; some NGVs
have two separate fueling systems that enable the vehicle to use either natural gas or a
conventional fuel (gasoline or diesel). In general, dedicated NGVs demonstrate better
performance and have lower emissions than bi-fuel vehicles because their engines are optimized
to run on natural gas. In addition, the vehicle does not have to carry two types of fuel, thereby
increasing cargo capacity and reducing weight. For model year 2008, the only commercially
available natural gas light-duty vehicle is the Honda Civic GX. Prior to model year 2006, CNG
technology vehicles were also commercially available from GM and Ford, mainly large trucks
and vans (DOE 2009i).

Propane

Today, most propane vehicles are conversions from gasoline vehicles. Dedicated propane
vehicles are designed to run only on propane; bi-fuel propane vehicles have two separate fueling
systems that enable the vehicle to use either propane or gasoline. No light-duty propane vehicles
are currently for sale in the U.S. Conversions are more popular in medium and heavy-duty
vehicle applications, especially for school buses (DOE 2009J).

Flex Fuel

Flexible fuel vehicles (FFVs) are capable of operating on gasoline, E85 , or a mixture of both.
Flexible fuel vehicles contain one fueling system, which is made up of ethanol compatible
components and is set to accommodate the higher oxygen content of E85. Other than fueling
capability and ethanol compatible components, FFVs are similar to their conventional gasoline
counterparts. Their power, acceleration, payload, and cruise speed are comparable whether
running on ethanol or gasoline. The only noticeable difference: fuel economy is lower when
FFVs run on ethanol. Flex fuel vehicles are available from each of the major automotive
producers, but the technology is mostly used in larger passenger automobiles,  SUVs and pick-up
trucks (DOE 2009k).

Hybrid

Hybrid electric vehicles (HEVs) typically combine the internal combustion engine of a
conventional vehicle with the battery and electric motor of an electric vehicle. The combination
offers low emissions, with the power, range, and convenient fueling of conventional (gasoline
and diesel) vehicles. Hybrid electric vehicles have the potential to be  two to three times more
fuel-efficient than conventional vehicles. For model year 2009, there  are 28 vehicle types
available for sale which utilize hybrid technology. By model year 2010, there are plans for at
least two commercially available plug-in hybrid vehicles  - the Chevrolet Volt and the Toyota
Prius - which have the potential to provide even greater fuel efficiency than current hybrid
vehicles (DOE 20091).

International surveys have shown that battery electric cars can meet the mobility needs of many
urban households, but they usually do not meet consumer expectations.  There is a growing focus
on the role electric vehicles can play in sustainable transportation. There is a Hybrid and Electric
Vehicles Implementing Agreement (HEVIA) which outlines the following objectives:

•    provide governments, local authorities, large users and industries with objective
     information on electric and hybrid vehicles and their effects on energy efficiency and the
     environment;
•    collaborate on pre-competitive research projects and related topics and to investigate the
     need for further research in promising areas; and
•    collaborate with other transport-related Implementing Agreements and to collaborate with
     specific groups or committees with an interest in transportation, vehicles, and fuels (IEA
     2009).

Fuel Cell

Fuel cell vehicles use a completely different propulsion system than conventional vehicles,
which can be two to three times more efficient. Unlike conventional vehicles, they produce no
harmful exhaust emissions—their only emission is water. Fuel cell vehicles are fueled with
hydrogen, which is considered an alternative fuel under the Energy Policy Act of 1992. Like
electric vehicles, fuel cell vehicles use electricity to power motors located near the vehicle's
wheels. In contrast to electric vehicles, fuel cell vehicles produce their primary electricity using a
fuel cell. The fuel cell is powered by filling the fuel tank with hydrogen. Fuel cell vehicles can be
fueled with pure hydrogen gas stored directly on the vehicle or extracted from a secondary
fuel—such as methanol, ethanol, or natural gas—that carries hydrogen. These secondary fuels
must first be converted into hydrogen gas by an onboard device called a reformer. Fuel cell
vehicles fueled with pure hydrogen emit no pollutants, only water and heat. Vehicles that use
secondary fuels and a reformer produce only small amounts of air pollutants.

No fuel cell vehicles are commercially available to consumers today.  They generally are only
available in limited numbers to select organizations with access to hydrogen refueling stations.
(DOE 2009m). Fuel cell vehicles will be listed in the DOE Alternative Fuels and Advanced
Vehicles Data Center (AFDC) Vehicle Make and Model Search when they become
commercially available (http://www.afdc.energy.gov/afdc/progs/vehicles  search.php).

Light Duty Ultra-low Sulfur Diesel

Light-duty diesel vehicles (passenger cars, light trucks and SUVs) are already available in the
U.S. with demand expected to double over the next 10 years. Vehicles using ULSD must meet
the same CAFE standards as gasoline-powered vehicles, but generally are more fuel efficient and
less polluting. Passenger car models from Audi, BMW, Mercedes-Benz and Volkswagen are
currently available, as are truck and SUV models from BMW, Chevrolet, Dodge, Ford, GMC,
Jeep,  and Mercedes Benz (DOE 2009n).

Other Vehicles

There are a variety of strategies that EPA is promoting which addresses the sectors of freight,
construction,  agriculture, ports, and school buses vehicles. The programs include switching to
cleaner fuels, retrofitting, repairing, re-powering, replacing equipment, and reducing idling. EPA
has promoted these changes by fostering partnerships, supporting innovative technologies, and
providing grants to accelerate clean diesel technologies.

Low-speed Vehicles

The National  Highway Traffic Safety Administration (NHTSA) defines a low-speed vehicle
(LSV) as ".. .a 4-wheeled motor vehicle, other than a truck, whose speed attainable in 1.6 km (1
mile) is more than 32 kilometers per hour (20 miles per hour) and not more than 40 kilometers
per hour (25 miles per hour) on a paved level surface.
                                          5-108               EPA Publication No. 315-R-09-001

                                                                             March 2010
                                          Energy Efficiency Reference for Environmental Reviewers
LSVs (low speed vehicles) are alternative means of transportation that drastically reduce the
amount of petroleum used by a conventional vehicle fleet. LSVs are suitable on roads with speed
limits of less than 35 mph, which makes them an excellent application for on-site use. LSVs are
prohibited for use on federal highways and their use may also be restricted by state and local
laws.

Low-speed vehicles are commonly utility or recreational vehicles and typically powered by
electric, gasoline or propane. Examples include airport baggage vehicles, small passenger
vehicles, golf carts, and small utility trucks. These vehicles are increasingly becoming more
important components of federal fleets, in response to fleet rightsizing requirements of EO
13423, energy savings, and the flexibility these vehicles provide. With an annual requirement of
a 2 percent reduction in petroleum fuel use for federal agencies, the impact of expanded use of
low speed vehicles is a key strategic component for compliance.

As an example, the Air Force has completed an assessment of plug-in electric pick-up trucks.
These vehicles were compared to the performance of a conventional pick-up truck and evaluated
for doing various types of work. Advantages of using a plug-in electric vehicle truck include:

•    Excellent for tasks that require short, moderately light load hauling.
•    Serve well as personnel taxi vehicles and enable access to tight, closed-in areas.
•    Batteries prove to hold their charge for an adequate time before needing to be recharged.

Disadvantages include:

•    Not multi-passenger pick-ups.
•    Limited off-road use.
•    Does not accommodate heavy loads.
•    Not suitable for 24 hour continual use due to battery recharging.

Medium -to-Heavy-duty Trucks

Medium-duty diesel vehicles serve a wide array of applications. With gross vehicle weight
ratings (GVWR) of about 8,500 to 26,000 pounds, they include everything from large pick-up
trucks and SUVs, to small school and transit buses, to cargo vans and "short-haul" trucks.  They
are the backbone of many fleets and consume  large quantities of fuel because of intensive  use.

Heavy-duty diesel vehicles include long-haul trucks, large buses, and other vehicles that are
heavier than 26,000 Ib GVWR.

Currently as much as 80% of U.S. goods by value of shipment are transported by trucks;
therefore, it is critical to improve truck transport energy efficiency in the movement of goods and
for services. Within the U.S. transportation sector, truck energy use has been increasing at a
faster rate than that of automobiles. Since 1973, all of the increase in highway transportation fuel
use has been due to trucks, mainly because of their extensive use in trade and commerce. Heavy
truck fuel efficiency is influenced by several factors, including basic vehicle design, zone of
operation, driver technique, and weather factors. Engine power losses and road losses

94% of the energy used to sustain vehicle speed at 65 mph (DOE 2006).

Truck design and performance

The 21st Century Partnership Truck Partnership is a collaborative effort of the DOE, DOT, DoD,
EPA and fifteen industrial partners supporting the development and implementation of
commercially viable technologies to reduce dependence on imported oil and improve air quality.
Through this program, the federal government and the trucking industry are working together to
develop prototype production heavy-duty trucks and buses with improved fuel efficiency,
reduced emissions, enhanced safety and performance, and lower operating costs. More
information can be found in The 21st Century Truck Partnership Roadmap and Technical White
Papers (http://wwwl.eere.energy.gov/vehiclesandfuels/pdfs/program/21 ctp_roadmap_2007.pdf).

Focus areas of research and testing include:

•    Diesel engine efficiency.
•    Advanced cylinder combustion, emission recirculation, and emission after-treatment.
•    Non-petroleum based diesel fuels.
•    Lightweight materials with required strength and stability.
•    Advanced heavy duty hybrid propulsion systems.
•    Aerodynamic improvements.
•    Auxiliary power management using electric, fuel cells, and waste heat recovery.
•    Input into idle reduction technologies and policies.
•    Advances in vehicle safety using video, improved crashworthiness, and improved braking,
     stability, and collision-avoidance technologies.

Another area of research into truck design is the potential use of hydraulic transmissions for
heavy-duty highway trucks. Hydraulic transmissions are routinely used for low-speed, heavy
duty applications such as off-road earth moving equipment, but have not been used for highway
use applications. New technology development allows the use of SuperDrive hydraulic
transmissions for highway use which uncouple the transmission from engine  speed and then use
an electronic control module to seek the lowest engine rpm for needed torque. Use of this
technology is anticipated to result in a 20-25% increase in fuel economy for heavy-duty trucks
and a 50-55% efficiency increase for light-to-medium duty vehicles. More information can be
found in An Innovative Approach to Improved Fuel Economy in Heavy-Duty  Trucks, Project
Fact Sheet (http://www.e3energy.org/fleming.pdf).

EPA established the National Clean Diesel Campaign (NCDC) to promote diesel emission
reduction strategies. NCDC includes regulatory programs to address new diesel engines as well
as voluntary programs.

NCDC regulatory programs for new diesel engines include the following:

•    2007 Heavy-Duty Highway Engine Rule: This rule will cut harmful pollutants from
     highway engines by more than 90 percent, resulting in an annual reduction of 2.6 million
     tons of NOX and 110,000 tons of PM when fully implemented.
•    The Clean Air Non-road Diesel Rule: This rule will cut emissions from new construction
     and agricultural and industrial engines by more than 90 percent.

Anti-idling measures

Historically, most idling activity occurs at truck stops, rail yards, and with government fleet
vehicles. Efforts to reduce idling have many benefits including:

•    Reduction in the emission of harmful air pollutants.
•    Reductions in fuel consumption, decreased maintenance costs,  and longer engine life which
     results in cost savings.
•    Reductions in noise levels.
•    Decreased dependency on fuel import.

Idling longer than ten seconds uses more fuel and produces more CO2 compared to restarting the
engine. Unnecessary idling wastes money and fuel and produces greenhouse gases that
contribute to climate change.

The GSA's Federal Acquisition Service offers the following facts and tips to help reduce fuel
consumption and idling.

•    Idling an engine for more than 30 seconds uses 2/10 of a gallon of fuel.
•    Idling a diesel engine does not warm it up.
•    A diesel  engine retains more heat longer when it is shut off instead of idling.
•    Driving the vehicle is the only way to properly warm it up.
•    Idling will cause a diesel to go into regeneration more frequently.
•    Implementing and enforcing anti-idling policies can cut your fuel consumption by 8% or
     more.
•    Frequently restarting of your engine increases wear by $10 per year.
•    Anti-Idle timers have been standard on GSA buses since 2006.
•    Diesel engines with High Horsepower improve fuel economy.
•    Automated manual transmissions can improve fuel economy by 19%.
•    Alternative lighting saves fuel, reduces down time, and improves safety.

Unnecessary idling occurs when trucks wait for extended periods of time to load or unload, or
when equipment that is not being used is left on. Long haul truck drivers idle their engines
during their rest periods to provide heat or air conditioning for the  sleeper compartment, keep the
engine warm during cold weather, and to maintain adequate battery voltage while using electrical
appliances such as a microwave oven or television set. Other reasons cited by truck drivers for
idling include  safety (i.e., keeping the windows closed, thereby needing cooling or heating) and
habit (i.e., protecting the engine by not turning it off). The EPA report, Study of Exhaust

Emissions from Idling Heavy-Duty Diesel Trucks and Commercially Available Idle-Reducing
Devices provides more information: http://www.epa.gov/otaq/retrofit/documents/r02025.pdf.

Reduced idling reduces fuel consumption. Regulations restricting idling were in place in almost
half the states as of July 2008. These regulations vary by state, county, or city, but typically
restrict idling to 3-10 minutes and do not distinguish between gasoline or diesel  vehicles. Most
of these regulations are relatively new and many have associated information campaigns to
increase awareness.

In May 2001, President Bush issued the National Energy Policy directing EPA and DOT to work
with the trucking industry to establish a program to reduce emissions and fuel consumption from
long-haul trucks. Responding to this directive, EPA initiated a comprehensive program aimed at
reducing idling. This includes organizing workshops, issuing grants, implementing
demonstration projects, and most importantly, closely examining idling fuel consumption and
exhaust emissions. The EPA SmartWay program (see Section 5.9.b) published a model "state
idling law" and EPA issued guidance on how states can incorporate projects to reduce long-
duration truck and locomotive idling into their air quality plans.

Several types of technologies exist that will effectively reduce long-duration idling. EPA
maintains a list of idle reduction technologies that can be accessed at the following website:
http://www.epa.gov/otaq/retrofit/.

Over the past seven years, EPA has evaluated idle reduction technologies as part of grants,
cooperative agreements, emissions testing, engineering analysis, modeling, and  external peer
reviewed reports. More information can be found at:  http://epa.gov/diesel/idle-ncdc.htm. To
date, EPA has verified the following idle reduction technology categories:

•    Electrified Parking Spaces (truck stop electrification)
•    Shore Connection Systems and Alternative Maritime Power
•    Auxiliary Power Units and Generator Sets
•    Fuel Operated Heaters
•    Battery Air Conditioning  Systems
•    Thermal Storage Systems
EPA, in collaboration with FHWA, developed the DrayFLEET model and four supporting case
studies, to assess truck emissions, and various technical and management options for reducing
emissions and fuel consumption from truck drayage activity
(http://www.epa.gov/otaq/smartway/transport/partner-resources/resources-drayage.htm). To
reduce truck queuing at terminal gates and associated vehicle emissions, operations tactics such
as gate time expansion and gate appointment systems can be used  (A Glance at Clean Freight
Strategies: Terminal Appointment Systems for Drayage,
http://www.epa.gov/smartway/transport/documents/drayage/420f06005.pdf). Gate time
expansion allows trucks to access port and freight facilities for a longer period of the day (up to
24 hour access) to reduce peak hour demand. The use of computerized inventorying, automated
gate controls and security devices, and other intelligent freight handling methods provides

efficient freight handling with reduced personnel needs. Gate appointment systems rely on
improved logistics whereby carriers are provided numerous reserved time slots during gate hours
when they can be assured of being handled efficiently. Both of these options allow the peak truck
demand periods at terminals to be spread out over longer periods and help reduce air quality
concerns due to less truck idle time.

Boats and Vessels

Green Vessel Design

Green vessel design is a growing area of interest in the marine sector, driven by rising fuel
prices. In addition to environmental benefits, maximizing the application of recycled and
renewable materials and minimizing discharges to water can help to increase efficiency. Duel-
fuel engines, which can use either diesel or liquefied natural gas, have been common on large
vessels for many years and are now being increasingly used in other higher speed vessels (DHS
2008). More information can be found in Green Vessel Design: Environmental Best Practices,
http://www.uscg.mi1/proceedings/articles/7 _King.%20Payne.%20Roberts.%20Villiott_Green%2
OVessel%20Design.pdf.

An area of interest in vessel design is the development of new materials which are lightweight
but provide the stability needed for use in marine environments. Advances in fiberglass
technology is a promising area which may have many applications for ship design and
manufacturing (DOE Glass Project Fact Sheet: Low Energy Alternative to Commerical Silica-
based Glass Fibershttp ://wwwl .eere. energy, gov/inventions/pdfs/mosci .pdf).

Vessel Building and Repair

Improvements in energy efficiency related to ship building and ship repair are mainly focused on
implementation of energy efficient compressed air systems, HVAC systems, lighting and motors
(EPA 2007).

Marine Remanufacture Program

EPA has adopted  a new emission control program for marine diesel engines that includes
emission standards for certain engines already in operation. The program is called the Marine
Remanufacture Program. Marine diesel engines are significant contributors to ambient levels of
ozone and particulate matter (PM) pollution in our nation's ports and along our rivers and
coastal waterways. EPA's latest emission standards for new engines will result in substantial
reductions of nitrogen oxides (NOx) and PM emissions from marine vessels. More information
can be found at EPA's website for frequently asked questions about the program:
http://www.epa.gov/OMS/regs/nonroad/marine/ci/420f09003.htm.

Engines built before the new-engine standards take effect, however, will continue operating
with higher emissions for a long time. The service life of many marine engines can be 30 years
or more. The Marine Remanufacture Program will provide early air quality benefits by reducing
                                          5-113                EPA Publication No. 315-R-09-001

                                         Energy Efficiency Reference for Environmental Reviewers
PM emissions from this legacy fleet sooner than would be the case through the normal turnover
of the fleet to vessels with new engines.

A marine diesel engine is covered by the Marine Remanufacture Program if it meets all of the
following criteria:

•    It is a commercial marine diesel engine.
•    It was manufactured between 1973 and the last Tier 2 model year.
•    It has power at or above 600 kilowatts (kW).
•    It has a displacement of less than 30 liters per cylinder.
•    It is installed on a vessel that is flagged or registered in the United States.

EPA is promoting a remanufacture system, commonly referred to as a "remanufacture kit,"
which  is a process for making an engine meet certain emission criteria - in this case, a 25 percent
reduction in PM emissions. The kit consists of instructions, specifications, limitations and/or
engine components. In  most cases,  a kit is expected to consist of "better" versions of parts
normally replaced or rebuilt and should not adversely affect engine reliability, durability, or
power.

Clean Ports USA

Clean Ports USA is an incentive-based, innovative program designed to reduce emissions from
existing diesel engines  and non-road equipment at ports. The program is for ports and fleet
owners who voluntarily engage in emission reduction strategies, including improvements in
cargo handling equipment, trucks, vessels, and other support machinery. The  focus of the
program is promoting the implementation of clean fuels; retrofit, repair and rebuild of existing
equipment; changes to and replacement of equipment to utilize more efficient and less
petroleum-based power sources; and operational strategies. Operational strategies include truck
idling measures and improved management of intermodal containers. More information can be
found at EPA's Clean Ports USA website: http://www.epa.gov/otaq/diesel/ports/basicinfo.htm.

Passenger Buses

Bus technology has, for several years, used compressed natural gas and liquefied natural gas to
power  large  passenger vehicles. Transit agencies,  schools, airports,  and large  parks are a few of
the users who have implemented the use of alternative fuel buses in the U.S. Today, all plug-in
electric hybrids and all  electric buses are commercially available and are beginning to be put into
use.

Fuel Cell Bus Benefits

The benefits of fuel cell buses includes being more efficient, clean,  quiet, low emissions, less
maintenance, and they reduce dependence on imported oil. Transit buses are good candidates for
fuel cell technology for the following reasons:

•    Their weight and  volume constraints are compatible for fuel cells.

                                          Energy Efficiency Reference for Environmental Reviewers
•    Central fueling stations minimize fuel logistic issues, which would apply to a bus system.
•    Fuel cell power requires no operational concessions.
•    Buses provide immediate environmental benefits to urban air quality if they reduce their
     emissions.
•    They allow the public an opportunity to learn, first-hand, about fuel cell technology.

Generation I and Generation II Fuel Cell Buses have been developed with plans for Generation
III fuel cell buses that will provide quick first start capabilities. The Generation III bus will be a
non-hybrid fuel cell power system that will operate on methanol, and it will be built upon a 40-ft
low floor bus platform for Americans with Disabilities Act (ADA) compliance, and have a low
curb weight.

Plug-In Hybrid-Electric School Buses

Another example of a bus using alternative energies is being followed in North Carolina's Wake
and Mecklenburg County school system, which is piloting plug-in hybrid electric school buses.
They cost two to three times more than a regular bus yet are expected to pay for themselves
through fuel efficiency within six years. They  are expected to reduce fuel consumption by 40-
50% and reduce emissions by 90%. More information can be found at the DOE website:
http ://apps 1 .eere.energy. gov/state_energy_program/proj ect_brief_detail. cfm/pb_id=l 23 0.

Electric Drive Lightweight Buses

Advances in electric battery technology and use of state of the art steel materials have been used
to develop a commercially-adaptable all electric bus. While originally designed using battery
technology, the vehicle could be alerted to eventually utilize a plug-in hybrid system using a
small diesel generator. More information can be found at the DOE website:
http://wwwl.eere.energy.gov/vehiclesandfuels/pdfs/success/lightweight buses.pdf

Hydrogen Buses

The state of Florida established a "hydrogen highway" for hydrogen powered buses. The Florida
Department of Environmental Protection (DEP) launched a "H2 Florida" statewide initiative to
accelerate the commercialization of hydrogen technologies and stimulate consumer interest.

Clean School Bus USA

The goals of Clean School Bus USA are to reduce children's exposure to diesel exhaust and the
amount of air pollution created by diesel school buses. Clean School Bus USA brings together
partners from business, education, transportation, and  public-health organizations to work
towards the following goals:

•    Encouraging policies and practices to eliminate unnecessary public school bus idling.

Locomotives

During normal railroad operations, locomotives sometimes must wait for freight cars to be
switched and/or picked up, for  another train to clear track on which the locomotive is to proceed,
or for mechanical service. Historically, locomotives have been left idling while they are waiting.
In some cases, there are practical or safety reasons why locomotives need to be left idling. In
other cases, locomotive operators might simply idle the engines  due to custom, habit, or
misunderstandings about diesel engines (EPA 2008b).

The reasons why current locomotives may need to be left idling  can be technological or related
to worker and passenger needs. First, diesel engines can be difficult to start in extremely cold
temperatures, especially larger  diesel engines such as those used in locomotives. Also,
locomotive engines are typically designed to use water without antifreeze because water is more
efficient at cooling the engine.  However, the water can freeze in cold weather and crack the
engine block. As a result, shutting locomotives off in cold weather has historically been avoided
as much as possible (EPA 2008b).

Locomotive engines may also need to idle in order to maintain critical functions such as  air
pressure for the braking and starting systems and battery charge. Maintaining air pressure for
braking is especially important since it can directly affect safety. Finally, in some  cases,
locomotives will idle to supply air-conditioning or heat to its crew and/or passengers, in part  to
comply with regulations and contractual requirements related to working conditions for the crew
(EPA 2008b).

EPA's regulatory efforts to reduce emissions from idling locomotives focus on requiring the
application of automatic idle reduction technologies to the locomotives themselves rather than
directly regulating when railroads may allow locomotives to idle. EPA issued emission
standards for locomotives in 1998, and updated these standards with a 2008 rulemaking. The
2008 rulemaking requires technology that reduces the amount of time a locomotive spends idling
(as well as applying tighter emission standards to new locomotives generally).  EPA is requiring
that all newly manufactured and nearly all remanufactured locomotives be equipped with idle
reduction technology that will automatically shut locomotives down if they are left idling
unnecessarily (EPA 2008b).

Several other technological developments that improve locomotive energy efficiency are
summarized below.

Gen Set Locomotives

A Gen Set Locomotive has three separate smaller engines instead of the one large engine found
in a conventional locomotive. The three smaller engines can provide horsepower on demand,
which is the ability to tailor horsepower output to the train weight and the territory the train will
travel over. A Gen Set Locomotive is 25 percent more fuel efficient than a conventional
locomotive.

Advanced Fuel Saving Control System for Freight Locomotives

General Electric is now commercializing the first planned advanced control system called
"Consist Manager". The device can be installed new or retrofit on GE Dash9 and AC-4400 class
locomotives. Two Class 1 US railroads are in the process of field evaluation.  The product can
achieve fuel savings of 1-2%. The product also lends itself to quiet operation of a lead unit at
part power operation.

Energy Efficient Coal Mining Locomotives

Battery vehicles have been introduced in coal mining locomotives to help overcome mobility
limitations of tethered vehicles. A fuel cell vehicle provides mobility and energy capacity of a
diesel unit and provides environmental benefits of electric vehicles.

Shore power plug-in unit

Plug-in units are relatively inexpensive and heat and circulate water and oil.  They have an
optional battery charger. Minimal equipment is required and they are ideal for commuter trains.
They can also be used for yard units.  A locomotive must be at an equipped location. There are
no local impacts. They are quiet and pollution-free.

Hybrid switching locomotives

Hybrid locomotives are in the demonstration stage.  They can replace a 2000 hp switcher.  They
use 125 hp diesel and 60,000 Ib of sealed Pb-acid batteries.  Small diesel charges batteries and it
runs when the switcher is in use.  The batteries are expected to last 10-15 years, yet the lifetime
is unproved at this point in time.  A hybrid switcher costs much more than add-ons.

Aircraft

Aircraft design

Blended wing design is an alternative airframe design which incorporates features from both a
traditional fuselage and wing design and flying wing design. This design provides improved lift
and weight savings, resulting in better fuel utilization. NASA  and the Air Force are currently
developing and testing prototype planes for potential future application in military and
commercial aviation. More information can be found at the NASA website:

Alternative propulsion planes

In April of 2008, Boeing completed the world's first manned flight using hydrogen fuel cells.
Similar fuel  cell technology potentially could power small manned and unmanned air vehicles.
Over the longer term, solid oxide fuel cells could be applied to secondary power-generating
systems, such as auxiliary power units for large commercial airplanes. Small, single-person
planes have  also been developed using electric battery and solar power. As with fuel cells, it is
unlikely that these technologies would have major impact on commercial aviation, but could
serve as auxiliary power sources in the future.

Biofuels

The Air Force has certified, or is in the process of certifying, much of its fleet to operate on a
50/50 blend  of synthetic fuel (derived from coal and biomass feedstocks) and JP-8 aviation fuel.
Commercial airlines are experimenting with synthetics, but they are currently unproven and not
available in adequate quantity to support commercial operations.

Transport and assisting equipment

The following are various assisting transportation equipment and devices that have been noted
through research, which can assist with creating more energy efficient transport.

•    Electric Aircraft PushBack Tractor (EAPT) - a propulsion  and energy management system
     for a battery-powered, electric aircraft pushback tractor.
•    Electric Aircraft Cargo Conveyor (EACC) - a battery-powered, self propelled belt
     conveyor for handling baggage and cargo at aircraft bulk cargo holds.
•    Limiting use of escalators and elevators - Limiting use times and not running escalators,
     elevators and moving walks when volumes are low.
•    Tractors and Trailers - EPA has certified SmartWay tractors and trailers. These tractors
     and trailers are outfitted with equipment that significantly reduces fuel use and emissions.
     There are  criteria for carriers to earn the privilege to label their vehicles with the SmartWay
     brand.
•    Monitoring GPS Devices - Onboard wireless location and performance monitoring GPS
     devices can help reduce idling and fuel costs.  The device identifies if the vehicle is
     consuming fuel as efficiently and cleanly as possible and identifies engines requiring
     maintenance.
•    Cabin video/audio Monitoring Devices - A cabin video/audio monitoring devices records
     and identifies when a vehicle exceeds a specific level.  They help identify and limit
     aggressive behavior.

energy efficiency upgrades, as well as the deployment of idle reduction technology, low-rolling
resistance tires, fairings (products to reduce aerodynamic drag) and other strategies.

The partnership currently includes over 2,200 participating transportation providers that supply
efficiency and emissions performance data to EPA through SmartWay emission models. EPA
uses individual company emissions and efficiency data to identify more efficient transportation
providers to purchasers of freight services. SmartWay assesses the freight practices of shipping
and logistics companies, based in part upon the environmental performance of the freight carriers
they use, to determine if these shippers can earn the SmartWay mark. SmartWay Partners -
carriers and shippers — with low greenhouse gas and high efficiencies are recognized with the
use of the SmartWay logo, an established mark of clean transportation.

Although initially targeted for commercial fleets, government agencies employing any freight
transportation services can utilize SmartWay to determine their freight related CC>2, NOX, and
PM emissions and energy use for both inventories and efficiencies. Using SmartWay will allow
Federal agencies to track and improve their freight transportation energy efficiency over time,
and will contribute toward providing market pressure on the industry to improve its efficiency.

Federal green purchasing programs have included a provision that federal agencies should seek
out freight providers that belong to the SmartWay partnership, which is focused on reducing
greenhouse gas and other emissions from goods movement including delivery of products to and
from federal buildings.  Federal fleets can also join SmartWay.

To assist trucking companies in reducing their emissions  and improving efficiency,  SmartWay
has identified a group of fuel saving technologies and has bundled them into a package known as
an "Upgrade Kit". They are highly fuel-efficient technologies with emission control devices to
reduce fuel consumption, idling, and emissions of greenhouse gases. Companies should
experience a full payback within one to three years. More information can be found at:

Vehicle Technologies Program

The DOE Vehicle Technologies Program
(http://wwwl.eere.energy.gov/vehiclesandfuels/index.html) works with industry to develop and
deploy advanced transportation technologies that can improve vehicle fuel efficiency and
increase the use of alternative fuels. The program has two major components:

FreedomCAR and Fuel Partnership.  These subprograms seek to develop emission- and
petroleum-free cars and light trucks and the infrastructure to support them. The Partnership
focuses on the research needed to develop the necessary technologies, such as fuel cells and
advanced hybrid propulsion systems.

21st Century Truck Partnership. This  program is a large public-private R&D partnership with
multiple federal partners including EPA, DOT, Commerce and DOE, along with several federal
laboratories, and private industry. The program addresses the research needs of commercial
vehicles (trucks and buses) with the aim to reduce pollution and dependence on fossil fuels.  The
technical goals of the program include developing more efficient engine systems and heavy-duty
hybrids, reducing parasitic losses that use up fuel (e.g., aerodynamic drag resistance, rolling
resistance, drivetrain losses, and auxiliary load losses), reducing idle time and improving safety.

The Vehicle Technologies Program also supports implementation programs that help to
transition alternative fuels and vehicles into the marketplace through its Clean Cities
subprogram.

Clean Cities Program

The DOE Clean Cities program (http://www 1.eere.energy.gov/cleancities/) is a government-
industry partnership designed to reduce petroleum consumption in the transportation sector by
advancing the use of alternative fuels and vehicles, idle reduction technologies, hybrid electric
vehicles, fuel blends, and fuel economy measures.  Clean Cities has a network of 90  or more
volunteer coalitions, which develop public-private partnerships to promote petroleum reduction.
Clean Cities provides equipment manufacturers, trade associations and other federal  agencies
with access to strategies and resources, and DOE incentives to fund petroleum reduction
projects.

Clean Cities sponsors the Alternative Fuels and Advanced Vehicles Data Center (AFDC), which
provides online technical data about fuels, vehicles, fueling station and truck-stop electrification
locations, infrastructure development, state and federal incentives and laws, technical and
outreach. AFDC tools include the Petroleum Reduction Planning Tool
(https://www.afdc.energy.gov/afdc/prep/index.php), which calculates petroleum reductions by
choosing one or a combination of the following methods:

•     Alternative Fuels                           •     Vehicle Miles Traveled Reduction
•     Hybrid Electric Vehicles                    •     Truck Stop Electrification
•     Biodiesel Blends                            •     Idling Time Reduction
•     Fuel Economy                             •     Onboard Idle Reduction

Hydrogen, Fuel Cells & Infrastructure Technologies Program

The DOE Hydrogen, Fuel Cells & Infrastructure Technologies Program
(http://wwwl.eere.energy.gov/hydrogenandfuelcells/about.html) works in partnership with
industry, academia, and national laboratories to research hydrogen production, delivery, and
storage technologies, as well as fuel cell technologies for transportation, distributed stationary
power, and portable power applications. The program focuses on addressing safety issues and
facilitating the development of model codes and standards, as well as demonstrating hydrogen
and fuel cell technology in real-world conditions.

Delivery technology for hydrogen infrastructure is currently available commercially, and  several
U.S. companies deliver bulk hydrogen. Some infrastructure is already in place because hydrogen
has long been used in industrial applications, but is not sufficient to support widespread
consumer use. There are very few hydrogen filling stations, and a limited number of hydrogen
pipelines throughout the country. The program promotes the construction of more filling  stations
and seeks other methods for hydrogen distribution, such as converting to hybrid natural
gas/hydrogen pipelines and using trucks, railcars, ships and barges (DOE 2009).

On-board hydrogen storage for transportation applications continues to be one of the most
technically challenging barriers to the widespread commercialization of hydrogen-fueled
vehicles. Although hydrogen has nearly three times the energy content of gasoline by weight, it
has four times less energy content by volume.  The program's research and development is
working on compression technologies to make widespread commercial hydrogen use more
feasible (DOE 2009).

Fuel cell research and development is aimed at reducing fuel cell system cost and size and
improving the performance and durability of fuel cell systems for transportation and for small
stationary and portable applications. Most of this research focuses on advancing polymer
electrolyte membrane (PEM) fuel cell systems.

EPA Sector Notebooks

The Sector Notebook series is a unique set of profiles containing information for specific
industries and governments. Unlike other resource materials, which are organized by air, water,
and land pollutants, the Notebooks provide a holistic approach by integrating processes,
applicable regulations and other relevant environmental information. There are 33 Industry
Sector Notebooks and 3 Government  Series that provide government officials with information
they need to comply with the environmental regulations that apply to their activities. Many of
them may provide useful information for the NEPA reviewer. More information about the
Sector Notebooks can be found in the Sector Notebook Factsheet located at:
http://www.epa.gov/compliance/resources/publications/assistance/sectors/notebooks/sector-

5.9.c Review considerations

309 Reviewers should identify whether energy efficiency requirements are addressed in EISs.  It
is understood that rather than repeating a lengthy discussion on these requirements, the EISs will
most likely incorporate them by reference by citing the appropriate document. Many times these
documents are made available via a link to a web site in the EIS.  In most cases, this should
suffice.

309 Reviewers should encourage agencies with federal actions involving federal vehicle fleets to
incorporate federal policies that include petroleum reduction and energy efficiency.  The Energy
Policy Act of 1992 (EPAct 1992), as amended by EISA, prohibits federal agencies from
acquiring light-duty vehicles and medium-duty passenger vehicles that are not low GHG-
emitting vehicles with exceptions, and further requires that 75% of all covered light-duty
vehicles acquired for Federal fleets must be AFVs  (where the fleets have 20 or more vehicles,
are capable of being centrally fueled, and are operated in a metropolitan statistical area with a
population of more than 250,000 based on the 1980 census).  In FY 2005, 58% of Federal vehicle
purchases  were considered exempt from EPAct 1992 requirements. Exemptions were granted
for fleet size, geographic location and use for emergency, law enforcement and national defense.

EPAct 1992 also set a goal of using replacement fuels to displace at least 30 percent of the
projected consumption of motor fuel in the United States annually by the year 2010. The Energy
Conservation Reauthorization Act of 1998 (P.L.  105-388) (ECRA) amended EPAct 1992 to
allow one  AFV acquisition credit for every 450 gallons of pure biodiesel fuel consumed in
vehicles over 8,500 pounds gross vehicle weight rating. "Biodiesel credits" may fulfill up  to 50
percent of an agency's EPAct 1992 requirements. The head of each Federal agency must also
prepare and submit a report to Congress outlining the agency's AFV acquisitions and future
plans by February 15th each year.

E.O. 13149, Greening the Government through Federal Fleet and Transportation Efficiency,
amended EPAct 1992 to direct Federal agencies  operating a fleet of 20 or more vehicles within
the United States to reduce their annual petroleum  consumption by at least 20 percent by the end
of FY 2006 (compared to FY 1999 levels) by using alternative fuels in AFVs more than 50
percent of the time, improving the average fuel economy of new light-duty petroleum-fueled
vehicle acquisitions by one mpg by FY 2002, and 3 mpg by FY 2006, and using other fleet
efficiency measures. E.O. 13149 was supplanted in 2007 by E.O. 13423, which requires Federal
agencies to decrease their fleets' petroleum consumption by two percent annually  and increase
non-petroleum consumption by 10 percent annually by 2015, using FY 2005 as a baseline.
Every federal agency is required to develop and implement a plan to meet this requirement.
Also, by 2010 each agency is to install at least one renewable fuel pump at each federal fleet
fueling center. Agencies must purchase plug-in hybrids when they are commercially available at
a reasonable cost.

EO 13514 expands the requirements of EO 13423 to establish a percentage reduction target for
agency-wide reductions of GHG emissions in absolute terms by fiscal year 2020.  In establishing
the target,  each agency shall consider reducing the use of fossil fuels by:
   •  using low greenhouse gas emitting vehicles including alternative fuel vehicles;
                                         5-122

                                         Energy Efficiency Reference for Environmental Reviewers
   •   optimizing the number of vehicles in the agency fleet; and
   •   reducing, if the agency operates a fleet of at least 20 motor vehicles, the agency fleet's
       total consumption of petroleum products by a minimum of 2 percent annually through the
       end of fiscal year 2020, relative to a baseline of fiscal year 2005.

Section 701 of EPACT 2005 amends EPAct 1992 to require Federal agencies to use alternative
fuels in fleet dual-fuel vehicles (flexible or bi-fuel) if the fuel is available within five miles or 15
minutes and does not cost more than gasoline on a per-gallon basis (FEMP 2008).

EISA 2007 created new and enhanced conservation requirements for federal vehicle fleets. The
Act raises corporate average fuel economy (CAFE) standards to 35 miles per gallon (mpg) by
2020. EISA also sets a renewable fuels standard for gasoline. The Act seeks to increase the
supply of biofuel by requiring fuel producers to use in the fuel mix a progressively increasing
amount of biofuel, culminating in at least 36 billion gallons of biofuel by 2022. EISA
differentiates between "conventional biofuel" (corn-based ethanol) and "advanced biofuel."
Advanced biofuel is renewable fuel, other than corn-based ethanol, with lifecycle greenhouse gas
emissions that are at least 50 percent less than greenhouse gas  emissions produced by gasoline or
diesel. Beginning in 2016, a progressively increasing portion of renewable fuels must be
advanced biofuels,  such as cellulosic ethanol. Under EISA, EPA is required to revise its
regulations to ensure that transportation fuel sold in or imported into the U.S. contains at least the
applicable quantity of renewable fuels.

Section 2862 of the National Defense Authorization Act of 2008 amends EPAct92 by expanding
the definition of a qualifying AFV for Federal fleets. Newly defined alternative fueled vehicles
include the following four types of vehicles:

•    a new qualified fuel cell motor vehicle (as defined in section 30B(b)(3) of the Internal
     Revenue Code of 1986);
•    a new advanced lean burn technology motor vehicle (as defined in section 30B(c)(3) of that
     Code);
•    a new qualified hybrid motor vehicle (as defined in section 30B(d)(3) of that Code);  and
•    any other type of vehicle that the Administrator of EPA demonstrates to the Secretary of
     Energy would achieve a significant reduction in petroleum consumption.

Section 30.B  of the Internal Revenue Service (IRS) Code (U.S. Code Title 26, Subtitle A,
Chapter 1, Subchapter A, Part IV,  Subpart B, Section 30.B) provides definitions of new qualified
fuel cell motor vehicle, new advanced lean burn technology motor vehicle and new qualified
hybrid motor vehicle.  (DOE 2008f). In a December 21, 2008  letter to DOE, EPA demonstrated
that operating a low GHG-emitting vehicle, as defined by EPA, would achieve a significant
reduction in petroleum consumption consistent with NDAA2008 section 2862 qualifying low
GHG-emitting vehicles as AFVs.

To help record progress in meeting the federal legislative requirements, the Office of
Management and Budget issues "Transportation Scorecards" for Federal agencies to document
status and progress for each agency in the areas of energy, transportation, and environment.

Through its Federal Acquisition Service and Federal Vehicle Standards program, GSA offers
services for fleet managers looking to improve energy efficiency.  GSA's website
(http://www.gsa.gov/Portal/gsa/ep/program View.do?pageTvpeId=17110&ooid=8060&programP
age=%2Fep%2Fprogram%2FgsaDocument.jsp&programId=15263&channelId=-24545) contains
Alternative Fuel Vehicles and Biodiesel Product Guides & Manuals that have pricing and
technical information to assist managers in selecting efficient vehicles and fuels.

EPA provides the Green Vehicle Guide, an interactive tool to compare the environmental
performance of vehicles (http://www.epa.gov/greenvehicles/Index.do). The tool also includes an
EISA 141 low GHG federal fleet calculator. The EPA/DOE fuel economy website,
http://www.fueleconomy.gov/ provides a tool for fleets to use for comparing the fuel economy of
various vehicles including hybrids, AFVs, and conventional vehicles.  FEMP and GSA also offer
the Federal Automotive Statistical Tool (FAST), a Web-based tracking tool that allows agencies
to input fleet data for many data collection requirements
(http://www.gsa. gov/Portal/gsa/ep/contentView. do?contentTvpe=GS A B ASIC&contentId=23 3 0
2&noc=T).

FEMP assists federal agencies with implementing the vehicle fleet mandates. A few strategies
and resources discussed in the Winter 2009 FEMP Focus newsletter include:

Acquire the right number and type of AFVs in the correct location. Placing AFVs where
alternative fuel is not available will not reduce petroleum consumption, and may make it more
difficult to reduce agencies' petroleum use if the AFV uses petroleum and gets fewer miles per
gallon than the non-AFV equivalent. Acquisition of AFVs should be part of an integrated plan
for petroleum reduction that takes advantage of available alternative fuel infrastructure, and uses
other types of vehicles where alternative fuel infrastructure is not available. In geographical areas
where there is alternative fuel  available, AFVs should be acquired, and fleet managers  should
ensure alternative fuel is used  in those AFVs to the greatest extent practicable. If a subfleet has
access to alternative fuel, an agency might consider composing the entire fleet of AFVs.

Biodiesel. Using biodiesel in diesel vehicles is another important option for fleets that have
limited access to alternative fuels for light-duty vehicles. Agencies can use B20 (a mixture of 20
percent biodiesel and 80 percent diesel fuel) to meet up to half of their AFV acquisition
requirements.

Develop an alternative fuel infrastructure. Public refueling stations are often willing to install
E85 pumps at no cost in areas  with high concentrations of Federal vehicles.  A publicly
accessible list of Federal fleet  E85-fueled AFVs without access to E85 is  available at:
www.afdc.energy.gov/afdc/data/fleets.html.

Update agency-specific polices and procedures. Agencies must develop and encourage policies
that ensure AFVs use alternative fuel to the greatest extent possible. Agencies may consider fleet

site visits or internal audits.  Some agencies have instituted a key card system that allows E85-
fueled vehicles to only refuel with E85 when refueling on site at an agency (FEMP 2009b).

5.10 Transportation Facilities

5.10.a Summary

A complete transportation system includes a variety of modes that seamlessly transport goods
and people. As a system, each mode is used to its maximum advantage and beneficial choices are
made with respect to the best movement of people and goods. Transportation mode choices
should maximize energy efficiency and effectiveness and form the core of a complete
transportation system.  This system may include (but is not limited to) the following modes:

•    Aviation
•    Highway
     Rail
•    Water-based transportation
•    Public transit
•    Bicycle/Pedestrian

Modal choice

Modal choice is the ability for one mode of transportation to be selected over another given the
preferences and requirements of the commuter or goods.  Mode choices are viable transportation
alternatives between the same origin and destination.  Differences in energy efficiency between
various transportation modes should be a consideration when planners are designing, maintaining
and upgrading transportation facilities.

The SmartWay Transport Partnership has tools and information to assist shippers and carriers
better understand the environmental and fuel consumption impacts of different modal choices
and other operational strategies for freight goods movement (www.epa.gov/smartway).

Intermodal Connectivity

The various modes are only one measure of a complete transportation system. A more important
measure is how the modes interact and ultimately perform with regard to the movement of
people and goods. Each mode has unique considerations that must be addressed to ensure a
seamless transfer of goods and people between modes.

When transportation improvements are contemplated, the following are design considerations for
each mode:

Highway

Highways typically form the spine, or backbone, of any community's transportation system.
Highways can provide both the accessibility of a local street to a specific destination, to the
mobility provided by an interstate highway. From a freight perspective, shippers and receivers
who use highway modes of transportation rely on the just-in-time delivery and door-to-door
convenience that motor carrier modes can offer.

                                         Energy Efficiency Reference for Environmental Reviewers
There are a number of design considerations to be made when evaluating the energy efficiency
of a proposed highway or improvements to an existing facility, including the ones bulleted
below:

•    High Occupant Vehicle (HOV) lanes - HOV lanes are dedicated to vehicles containing
     two or more passengers. Implementation of HOV can increase the overall throughput and
     efficiency of the highway facility by incentivizing carpooling and ridesharing.
•    High Occupant Toll (HOT) lanes - This is a form of road pricing where drivers of single-
     occupant vehicles must pay a toll for use of lanes  or roadways that have been designated
     for use of high occupancy vehicles. While HOT lanes may not reduce overall demand, they
     do affect the redistribution of demand, allowing for the roadway to operate more
     efficiently.
•    Truck-only lanes - These lanes improve the operating efficiency of the roadway by
     removing slower-moving vehicles such as trucks from the mixed-flow of the overall
     vehicle stream.  This contributes to the stabilization of traffic flow, and reduces congestion.
•    Design speeds - A roadway may be  designed for a higher speed, but posted at a lower one
     to improve fuel efficiency as well as  safety.
•    Grades - Grade considerations are particularly important for trucks, as lower gradients
     result in improved operation and greater fuel efficiency.
•    Energy efficient lighting-Older style mercury vapor lamps are inefficient. Converting
     from mercury vapor lamps to more efficient options, such as metal halide,  can reduce
     energy consumption.
•    Upgrades to LED signals - LED signals (light emitting diode) can provide electricity
     savings of up to 90 percent over incandescent lamps and can last up to six times longer.
     While somewhat expensive to install, the energy cost savings can quickly eclipse the costs
     of installation. LED signals improve signal visibility and safety while reducing energy
     costs. They also produce more light per watt than the traditional incandescent bulb.
•    Signal interconnection and coordination -Interconnection and coordination can allow a
     platoon of traffic to "pulse" through  a corridor, producing a short term reduction in
     congestion and  decreasing the fuel use caused by wasted "green time," or unnecessary
     idling of vehicles.
•    Transit-friendly features (bus pulloffs, signal pre-emption, etc.) - these features should
     be considered during the design of a  roadway. Accommodating larger transit vehicles can
     remove them from the cartway. Signal pre-emption also reduces wasted green time and
     unnecessary vehicle idling.
•    Smart Toll Collection - For toll facilities, advances in technology now make it possible to
     collect tolls more efficiently than through traditional toll booths. A variety of electronic
     systems and devices such as transponders and "Smart Cards" make the collection of tolls
     technically feasible and more efficient.

Parking Facilities

Every vehicular trip begins and ends in a parking place. Some studies have  suggested that there
are four parking  spaces for every car in the U.S. (Shoup 2005). Municipal zoning ordinances
typically establish off-street parking requirements to accommodate the busiest of shopping days,


                                          5-132               EPA Publication No. 315-R-09-001

                                                                             March 2010
                                          Energy Efficiency Reference for Environmental Reviewers
leaving an overcapacity of parking spaces throughout the rest of the year. This contributes to the
urban heat island effect, among other undesirable conditions. A secondary issue involves the cost
of parking itself. With the exception on urban on-street parking and parking structures, a
majority of parking facilities are either free or underpriced. This incentivizes single occupant
vehicle travel and its resultant energy use. On-street parking that is underpriced also contributes
to a process known as "cruising," where motorists searching for parking must mix with other
traffic, creating congestion and delay.  Constructing an appropriate inventory of parking spaces,
coupled with proper pricing, would encourage the use of more efficient modes of transportation,
such as bicycle/pedestrian, or public transportation.

Public Transportation

Transit can help communities operate more energy efficiently by reducing the need for single
occupancy vehicle roadway and parking investments. Transit can operate most effectively when
it is operated with complementary facilities such as the ones bulleted below:

•    Transit Oriented Development (TOD) - Orienting development or higher density,
     mixed-use developments around key transit nodes and activity centers can help make
     transit operate more efficiently. Pedestrian/bicycle access and the use of public
     transportation have  multiplier impacts on energy efficiency. Pedestrian/public
     transportation trips not only conserve energy by reducing automobile use, but also reduce
     the heat island effect. Higher development densities, complementary land uses, and
     pedestrian-oriented  design all help to promote transit. EPA's Smart Growth website
     provides information on transit oriented development:
     http://www.epa.gov/smartgrowth/index.htm.
•    Park and Ride facilities - These complementary facilities can expand the  catchment area
     of a transit operator. Park and rides should be located at areas within a defined travel shed
     (between major origins and activity centers) and should include parking for both vehicles
     and bicycles.
•    Bus Rapid Transit (BRT) and/or Bus-only lanes - This service attempts  to match the
     service quality  of passenger rail while still realizing the fuel efficiency savings of bus
     transit. Since it is segregated from other roadway lanes, it provides a higher level of
     operating efficiency, even though additional right-of-way may initially need to be acquired
     for its construction.
•    Bike racks on  buses - The availability of bicycle racks on buses also expands the potential
     service area of the transit operator and can lessen demand for other, less energy efficient
     forms of transportation such as the single occupant vehicle.

Passenger Rail

Passenger rail  service can relieve congestion (and reduce fuel consumption) at a fraction of the
cost of building extra highway capacity. The availability of other intermodal facilities and
services such as park and ride lots and provisions for bicycles on trains can increase the capture
rate of passenger rail. Passenger rail stations should be located within the center of the
community where they can be easily accessed by multiple modes (i.e., bicycle, pedestrian, inter-
and intra-city bus, etc.) and provide easy access to destinations such as employment,


                                           5-133                EPA Publication No. 315-R-09-001

                                          Energy Efficiency Reference for Environmental Reviewers
entertainment, and shopping.  Transit oriented development around stations makes rail more
accessible as an energy efficient mode of travel.
Rail Freight

Rail freight has been an important element of the U.S. transportation system for over 150 years.
Because they are not as flexible as highway/motor carrier modes, freight railroads have
historically been dominated by lower value bulk shipments with flexible shipment timetables
(e.g., coal), . and have been most effective in delivering goods in excess of 300 miles. With
major growth occurring in intermodal shipping, and advent of double stack trains, rail now has
increased ability to facilitate the movement of relatively high value materials, including materials
shipped in ocean containers, trailers, and automobile rail car carriers. Inbound containers are
often higher value finished products (e.g., retail goods for Wal-Mart.)  In addition, short line rail
roads can serve as feeders for larger rail lines in moving freight to distribution centers.

Rail freight should be evaluated as an energy-efficient means of transporting goods, depending
on the type (value) of product being shipped, and the distance involved. A typical rail car can
remove as many as four trucks from the highway. Removing trucks from state highways and
local roadways around ports and congested communities heightens rail freight's environmental
benefits. A few methods to consider in planning for the effectiveness of rail freight modes
include:

•    Train make-up/block management - More than any  other train type, intermodal trains
     suffer from their equipment design and loading pattern. Large gaps between the cars
     directly affect the aerodynamic drag of the train. Matching intermodal loads with cars of an
     appropriate length reduces the gap length between loads and improves air flow. Filling
     empty slots with empty containers or trailers also reduces  aerodynamic resistance and
     improves energy efficiency, despite the additional weight penalty and rolling resistance.
     Depending on particular train configuration, train resistance can be lowered by as much as
     27 percent and fuel  savings by 1 gal/mi per train (TRB 2005). These techniques can be
     applied to manifest trains (trains which carry almost any kind of freight) as well.
•    Electrification of lines - Electrification has a significant initial cost, but can provide long-
     term energy savings over diesel engines, particularly on high-volume lines.
•    Double stack container accommodation - Moving freight via double-stacked rail freight
     containers can significantly reduce the amount of locomotive power needed to move the
     same freight under more conventional methods. The application and accommodation of
     double-stack rail facilities (e.g., raising bridges and lowering tunnels, etc.) has a significant
     initial cost, but can improve the fuel efficiency of the rail freight operator.
•    Sealed corridors - One of the most significant concerns for railroads involves right of way
     crossings. Grade separation at crossings or elimination of crossings improves train speeds,
     and saves energy by precluding vehicles idling at crossings.
•    Lighter vehicles - Use of composites and other materials that would reduce car weight and
     efforts to reduce friction/rolling resistance would require less energy and improve overall
     system performance.
                                          5-134                EPA Publication No. 315-R-09-001

                                         Energy Efficiency Reference for Environmental Reviewers
•    Improve rail logistics - Adding rail capacity (e.g., double-tracking, etc.) can improve train
     scheduling and tracking and lessen dwell times in rail sidings. It also reduces total hours of
     service (and energy consumption) by increasing throughput.
•    Train yards and facilities - energy efficiency review may be undertaken at train yards and
     facilities, many of which have been in operation for decades. Recommendations on
     insulation, HVAC, lighting, etc. and the resultant energy savings should be examined. See
     Section 5.4 for recommendations on improving energy efficiency for buildings and
     lighting. Reduction of truck and locomotive idling can also improve energy efficiency at
     rail facilities (see Section 5.9.b Federal Vehicle Fleets for a discussion of idle reduction
     strategies).

Airports

Airports transport both people and freight. In the case of the former, the Federal Aviation
Administration (FAA) reports that passenger traffic has tripled since 1970 and is expected to
double again by 2025. In the case of the latter, aviation is used to transport a mix of high and low
value products. The schedule flexibility of air travel permits time sensitive product delivery, an
increasingly important aspect for manufacturers seeking to optimize the efficiency of their
supply chains. However, airports can also be voracious energy consumers, and the opportunity
exists for substantial energy efficiency improvements.

The Clean Airport Partnership (CAP), a U.S. non-profit corporation, works to  improve
environmental quality and energy efficiency at airports. Recently, CAP's primary focus has been
implementation of the Green Airport Initiative (GAI), which is a comprehensive, streamlined
approach for helping airports shrink their environmental footprint while creating a blueprint for
sustainable development. The GAI was designed and implemented with financial support from
DOE, EPA, the Rockefeller Foundation, and the U.S. Congress.  More information on the GAI
can be found  at: http://www.cleanairports.com/.

Airport systems that are among the largest electricity consumers include:

•      Lighting systems
•      Heating, ventilation, and air conditioning
•      Motors and machine drives
•      Office equipment like computers, copiers, and printers
•      Tenant facilities like concessionaire kitchens (Sea-Tac 2007)

Many of the strategies listed in Section 5.4 Buildings, can be applied to airports. In addition the
airport building(s) itself, there are a variety of ways in which airport operations can improve
energy efficiency, such as those outlined below:

•    Intermodal Approaches - Provide intermodal connections for employees and travelers to
     access the airport while using other modes, such as public transportation, passenger rail or
     ride-sharing. Employees can be provided with transit vouchers or similar benefit to
     encourage commuting by these energy-saving modes.
                                          5-135                EPA Publication No. 315-R-09-001

                                          Energy Efficiency Reference for Environmental Reviewers
•    Signing - an effective signing program can help travelers find available parking and airline
     check-in facilities more quickly, thus reducing the amount of time and fuel visitors spend in
     re-circulating through airport facilities.
•    Congestion pricing - Charging commercial vehicles for each time they enter the airport
     can promote energy conservation by discouraging needless travel and reducing the total
     number of trips made. These systems can reduce shuttle trips by 25-40% (Sea-Tac 2007).
•    Reduced vehicle idling - Airports can mandate the length of time that authority vehicles
     idle, thus saving on energy costs. Some airports such as the Port of Seattle have constructed
     cell phone lots to discourage drivers who are awaiting passengers from re-circulating
     through the  airport or from idling their vehicles on adjacent access roads.
•    Pay on Foot Parking - Pay-on-Foot parking speeds egress from parking garages (and
     reduces idling) by enabling motorists to pay their fees in the  terminal and to submit their
     receipt through an automated system upon exiting.
•    Escalators - Most escalators consume full power constantly. Turn off escalators when not
     in use and retrofit escalators with energy efficiency kits (e.g., Ecostart, which allocates
     power "in direct proportion to the required workload, eliminating wasted energy") (Sea-
     Tac 2007).
•    Rental facilities - Airports can locate all rental car facilities at one location.  This reduces
     number of shuttle buses that operate to move passengers between terminals and the rental
     car facility.

Energy efficiency strategies that can be applied to aircraft and ground support equipment can be
found in Section 5.9, Federal Vehicle Fleets.

Water-based transportation

The emergence of containerization over the past 50-60 years has allowed for the transport  of
virtually any type of consumer product. Water-based transportation specializes in containerized,
bulk and breakbulk cargo and can carry commodities over long distances. With water-based
transportation, goods must be transferred unless a shipper or receiver is located along a
waterway. This makes the efficiency of intermodal transfer to highway and rail vitally important
for energy efficiency.  Some considerations for improving the energy efficiency of water ports
include:

•    Draft Depth - In taking advantage of economies of scale, vessel size has been continually
     increasing through the years for improved cost effectiveness and overall energy efficiency.
     As such, adequate channel depth and wider locks are needed to accommodate larger  vessels
     and facilitate efficient movement between terminals. Vessels that cannot be accommodated
     at smaller ports must offload a portion or all of their cargo to other modes of transportation
     in shipping to a final destination. The land bridge portion of the intermodal move  may
     often be more energy intensive than water-based transport. Where possible, increasing
     channel depth and lock width to accommodate larger vessels can facilitate increases  in
     efficiency.

•    Port facilities - water ports that have rail freight sidings with direct access to terminals and
     docks minimize the amount of drayage involved in moving cargo from the ship to its final
     destination.

Considerations for congestion mitigation

The broad area of congestion mitigation can be important to the efficient use of energy on the
highway system. Efforts to reduce congestion and improve traffic flow can reduce fuel
consumption for all transportation modes at least in the short term.  Long-term  strategies for
improving energy efficiency may require a more comprehensive evaluation of the transportation
system.The range of possible mitigation strategies should be applied to address specific corridor
needs.  These potential strategies generally fall into three categories:

1.    Additional capacity
2.    Operational improvements
3.    Demand management

FHWA has identified numerous mitigation techniques associated with each category. In reality,
the most successful approach may be to implement a combination of appropriate strategies from
all three categories.

A situation-appropriate selection of FHWA's suggested mitigation techniques can be
implemented through consideration of this framework for responding to congestion and
identifying potential solutions. While it is appropriate to segregate improvements by Capacity
Enhancement, Operational Improvements and Demand Management, it may be also be
beneficial to segregate Modal Options into their own classification.

Capacity Enhancements can include new roadways and roadway widening for additional single-
occupancy vehicle lanes (SOV), but may also include minor geometric enhancements and the
elimination of bottlenecks. Large-scale capacity enhancements are typically the last measures
transportation professionals consider, because they are often the most expensive and can have
adverse environmental impacts, such as environmental and right-of-way impacts. Large-scale
capacity enhancements can also have the effect of inducing additional travel, which may result in
the roadway becoming congested again in the future; however, strategic capacity enhancements
can alleviate existing congestion and may accommodate some future growth if properly
considered. Capacity enhancements that can be considered include:

•    New SOV Facilities - new roadways, interchanges, or ramps that increase single-
     occupancy vehicle lane-mileage on the transportation network.
•    Lane Additions - new travel lanes on an existing roadway designed to increase the capacity
     of the facility; does not including turning lanes, acceleration/deceleration lanes, climbing
     lanes, or specialized lanes for use by modes other than single-occupancy vehicles.
•    Elimination of Bottlenecks - removal of a physical constriction which delays travel, such
     as widening an underpass, providing lane continuity (i.e. replacing a two-lane bridge that
     connects pieces of four-lane roadway), or eliminating a sight barrier. FHWA's publication,
     Traffic Bottlenecks: A Primer Focus on Low-Cost Operational Improvements
     (http://ops.fhwa.dot.gov/publications/bnprimer/index.htm) provides low-cost strategies for
     the elimination of bottlenecks.
•    Intersection/Geometric Improvements - addition or reconfiguration of turning lanes, lane
     widening, realignment of intersecting streets, improved acceleration or deceleration lanes at
     interchange ramps.

Operational Improvements are geared toward improving the "supply side" of the transportation
system. These efforts are intended to enhance the operation of the transportation system and
make it as efficient as possible. Operational improvements include things such as intersection
upgrades, access management, reversible lanes, traffic signal  improvements, and Intelligent
Transportation Systems.

Operations represent technologies and institutional arrangements that allow transportation
systems to operate more closely to their maximum design intent. Operational improvement
include:

•    Traffic Signal Improvements - signal hardware upgrades, signal software upgrades,  signal
     timing, multi-jurisdictional signal coordination, or (in conjunction with intersection
     improvements) channelization of turning movements.
•    One-way Streets/Circulation Adjustments - establishing, or removing, pairs of one-way
     streets in place of a standard two-way street.

                                         Energy Efficiency Reference for Environmental Reviewers
•    Incident Management Systems - technology and programs for detecting crashes, disabled
     vehicles, or other incidents that impede travel and resolving or removing the obstructions.
•    Intelligent Transportation Systems (ITS) - the use of technology (Closed Circuit Television
     (CCTV), Dynamic Message Sign (DMS), Highway Advisory Radio (HAR), etc.) to
     improve traffic flow with respect to incident management and traveler information. The use
     of technology must include supporting operations and maintenance of that technology.
•    Institutional Programs and Procedures - establishing institutional relationships to address
     congestion, especially non-recurring congestion. These relationships may include special
     events management, incident management and traveler information as well as traffic signal
     operations. The partnerships can be used to develop inter-agency procedures to address
     certain congestion issues.
•    Special Events Management - establishing coordinated management of special events.

Demand Management programs attempt to address congestion at the root of the problem by
reducing the number of vehicles on the road. These initiatives work to modify driver behavior by
encouraging people to make fewer single-occupancy trips, travel in off-peak hours when
possible, and support land use policies that reduce the demand for automobile transportation.
Examples include:

•    Growth Management - public policies to manage the location and nature of development in
     a way that optimizes transportation efficiency. These include "Smart Growth" initiatives.
•    Access Management - policies, design criteria, and facilities that minimize the number of
     driveways and intersecting roads accessing a main thoroughfare; includes parallel service
     roads, shared driveways, median barriers, and curb cut limitations. While many consider
     access management an operational improvement, the policies associated with them lend
     themselves to demand reduction on arterials and some collectors.
•    Transit-Oriented Development (TOD) Policies - public policies that encourage
     concentrated development adjacent to transit stops or stations and easy access to these
     transit facilities.
•    Employer-Based Programs - encouraging telecommuting, flexible or staggered work
     schedules, company-run carpool/vanpool programs, promotion of transit usage, and
     parking management at the job site.
•    Public Relations & Education for TDM - education and publicity that discourages single-
     occupancy vehicle travel during peak hours and provides information on alternate modes of
     travel and ways to minimize travel.
•    Public Relations & Education for Transportation-Supportive Development - educational
     programs for policy makers and the general public about the impact of development
     decisions on transportation systems in order to promote informed decision-making.

Modal Options include techniques to give people transportation choices beyond just driving
alone in their cars. These include initiatives to encourage carpooling, vanpooling, transit, bicycle
and pedestrian modes of travel.

•    Improved Transit Service - new routes and/or expanded schedules, but not including new
     facilities. Where possible, coordination should take place such that planning and transit
     activities are coordinated to support existing and future service needs.

                                          Energy Efficiency Reference for Environmental Reviewers
•    Transit Capital Improvements - new transit facilities such as busways, dedicated bus lanes,
     and bus pull-off to increase transit accessibility and usage.
•    Park-n-Ride & Other Intermodal Facilities - outlying parking lots that encourage transit
     use, carpooling and vanpooling or other facilities that facilitate transfer from one mode of
     travel to another.
•    Rideshare Programs - programs to facilitate carpooling and vanpooling.
•    Pedestrian Facilities & Information - sidewalks, crosswalks, paths, pedestrian signals,
     pedestrian bridges, maps and signage to promote walking as a viable mode of
     transportation.
•    Bicycle Facilities & Information - bike lanes, paths, signals, lockers, maps and signage to
     promote bicycling as a viable mode of transportation.

During the preliminary screening process, congestion strategies can be subjectively evaluated for
suitability and potential benefit. The rating of suitability and potential benefit can result in a
matrix that helps determine which strategies should be high, medium and low priorities. The
preliminary  screening provides some context as to the range and magnitude of possible
mitigation techniques. Ultimately, it is likely that additional detailed evaluation may be required.

In July 2009, the Urban Land Institute published the report, Moving Cooler: An Analysis of
Transportation Strategies for Reducing Greenhouse Gas Emissions.  The report was prepared for
a steering committee that included FHWA, FT A and EPA. A broad variety of transportation
strategies are evaluated.  Strategies relevant to improving energy efficiency included:

•    Travel Activity—Reducing the number of miles traveled by transportation vehicles, or
     shifting those miles to more efficient modes of transportation.
•    Vehicle and System Operations—Improving the efficiency of the transportation network so
     that a larger share of vehicle operations occur in favorable conditions, with respect to speed
     and smoothness of traffic flow, resulting in more fuel efficient vehicle operations.

The report advocates for an integrated multi-strategy approach, and emphasizes that measures
that reinforce efficient driving — either through regulation (speed limit reductions) or education
(eco-driving) are especially effective. Integrated land use strategies and transit capital
investments, such as urban transit expansion and intercity and high-speed rail, were also found to
reduce fuel consumption.  More information can be found at: http://movingcooler.info/.

5.10.c Review Considerations

309 Reviewers should identify whether energy efficiency requirements are addressed in EISs. It
is understood that rather than repeating a lengthy discussion on these requirements, the EISs will
most likely incorporate them by reference by citing the appropriate document. Many times these
documents are made available via a link to a web site in the EIS.  In most cases, this should
suffice.

When considering energy efficiency within transportation facility related EISs, 309 Reviewers
will need to consider the individual purpose and need for each project. The purpose and need
should clearly state the transportation needs that exist, and the alternatives analysis should
thoroughly document the reasons for the  selected modal choice.

In terms of operation, proposed capacity  improvements projects should document the changes in
energy use or efficiency. Capacity improvements could have differing impacts on proposed
energy use depending upon the mode and the nature of the planning improvements. An EIS
should also quantitatively document the congestion mitigation benefits of the proposed action,
via analysis such as changes in delay, level of service, vehicle miles traveled, vehicles hours
traveled, travel time savings, etc. To fully appreciate the benefits of congestion mitigation, EIS
reviewers could suggest that the agency relate congestion mitigation to energy savings via
improved travel efficiency, reduction of idling, etc.

The construction of new transportation facilities, or upgrades of existing facilities, should
consider the energy efficiency of construction methods and materials. Mitigation commitments
documented in the EIS should include efforts to improve energy efficiency of construction. See
Section 5.4, Buildings, for recommendations  on reducing energy use in construction. For
highway construction, reviewers can consult the EPA Green Highways Partnership website
http://www.greenhighways.org/index.cfm for additional recommendations on applicable energy
efficiency strategies (click on Resources  for green  highways technologies and case studies). For
other suggestions on construction techniques, the Low Impact Development Center
http://www.lowimpactdevelopment.org/ provides innovative approaches to "green" construction
techniques.

5.11 Other Operations

5.11.a Summary

Energy efficiency can be evaluated as an issue in EISs for other operations, including research
and development (R&D) programs, operation of uranium enrichment facilities and power plants,
nuclear power plants, dredging, development of water and wastewater infrastructure, mining and
other resource extraction projects, and electricity transmission and distribution.

5.11.b Related Federal Partnership Programs

Federal agencies, particularly DOE and EPA, offer a range of programs to support energy
efficiency improvements. They include the following:

•    Energy Conservation and Renewable Energy Reserve (CRER): As an incentive to conserve
     energy and to use renewable energy resources (such as biomass, solar, geothermal, or
     wind), the Energy Reserve (58 FR 3618-3701) was established as part of the Acid Rain
     Program. CRER has a pool  of 300,000 air emission allowances. Utilities that meet
     standards by implementing  demand-side conservation measures or by using renewable
     energy resources will be awarded the allowances by the CRER. These allowances can be
     banked for future use as part of a compliance plan or sold.

•    Coalbed Methane Outreach Program (CMOP): CMOP is an EPA program with the goal of
     reducing methane emissions from coal mining. CMOP promotes the profitable recovery
     and use of coal mine methane, a greenhouse gas (EPA 2009a).

•    The Coal Combustion Products Partnership (C2P2): The C2P2 program is a cooperative
     effort between EPA and the American Coal Ash Association (ACAA), Utility Solid Waste
     Activities Group (USWAG), DOE, FHWA, the Electric Power Research Institute (EPRI),
     USDA Agricultural Research Service (ARS) to promote the beneficial use of coal
     combustion products (CCPs) (EPA 2009f).

•    Landfill Methane Outreach  Program (LMOP): LMOP is an EPA program to promote use of
     landfill gas as a renewable,  green energy source. Landfill gas (mainly carbon dioxide and
     methane) is the natural by-product of the decomposition of solid waste in landfills. Landfill
     gas energy projects also provide the benefit of preventing emissions of methane (a
     powerful greenhouse gas) (EPA 2009b).

•    AgStar:  This joint effort of EPA, USDA, and DOE "encourages the use  of methane
     recovery (biogas) technologies at the confined animal feeding operations that manage
     manure as liquids or slurries. These technologies reduce methane emissions while
     achieving other environmental benefits" (EPA 2009c).

•    Methane to Markets Partnership: An international  initiative that advances cost-effective,
     near-term methane recovery and use as a clean energy  source. The Partnership acts as a
                                         5-145               EPA Publication No. 315-R-09-001

     mechanism to bring together interested parties from governments and the private sector to
     facilitate methane project development and implementation around the world (EPA 2009d).

•    Natural Gas Star: EPA partners with oil and natural gas companies to adopt proven, cost-
     effective technologies and practices that improve operational efficiency and reduce
     methane emissions (EPA 2009e).

•    National Industrial Competitiveness Through Efficiency: Energy, Environment and
     Economics (NICE3): DOE's Office of Industrial Technology's NICE3 program "provides
     grants to state and private sector partnerships to demonstrate emerging, energy efficient
     technologies that will benefit the Industries of the Future. The program provides up to
     $525,000 (50% cost sharing is required) for the first commercial demonstration of
     innovative industrial technologies that reduce energy consumption, waste generation, and
     operating costs. Applications must be submitted by an authorized state agency with an
     appropriate industrial partner" (DOE 2001).

•    Power Marketing Administrations: DOE's Power Marketing Administrations market and
     deliver through transmission systems the power produced at federal water projects in
     excess of project needs in such a manner as to encourage its most widespread use at the
     lowest possible rates to consumers consistent with sound business principles. The four
     regional Power Marketing Administrations are Western Area, Bonneville, Southeastern,
     and Southern (DOE 2009a).

•    EPA Sector Notebooks: The Sector Notebook series is a unique set of profiles containing
     information for specific industries and governments. Unlike other resource materials,
     which are organized by air, water, and land pollutants, the Notebooks provide a holistic
     approach by integrating processes, applicable regulations and other relevant environmental
     information. There are 33 Industry Sector Notebooks and 3 Government Series that provide
     government officials with information they need to comply with the environmental
     regulations that apply to their activities. Many of them may provide useful information for
     the NEPA reviewer. More information about the Sector Notebooks can be found in the
     Sector Notebook Factsheet located at:
     http://www.epa.gov/compliance/resources/publications/assistance/sectors/notebooks/sector

Research and Development Programs

The possibilities for introducing energy efficiency into R&D programs range as wide as the
subjects of the R&D activities themselves. Many review considerations identified in other
sections of this document could be relevant, depending on the details of the proposed action,
including the following:

•    Procurement of appliances and equipment (Section 5.1)
•    Facility siting (Section 5.2)
•    Construction and buildings (Sections 5.3 and 5.4)
•    Laboratories (Section 5.7)

Other activities that could present opportunities for energy efficiency include water conservation
measures in agricultural R&D projects, and teleconferencing, videoconferencing, online
reporting, and use of electronic data in management activities for large research programs.

Uranium Enrichment Facilities

Nuclear reactor fuel requires a higher concentration of the uranium-23 5 (U235) isotope than
exists in natural uranium ore. Normally, the amount of U235 is enriched from 0.7% of the
uranium mass to about 5%. Gaseous diffusion is the only process currently used in the U.S. to
enrich uranium for use as nuclear reactor fuel (NRC 2008). Gaseous diffusion involves heating
the solid form of uranium fluoride (UFe) that was received by the facility until its gaseous form
                                  9^4      9^ S                                     9^R
is reached. In gaseous form, lighter U   and U   atoms are separated from the heavier U
though diffusion barriers. The resulting UFe gas,  enriched with the U235 isotope, is condensed
into a liquid, solidified, and transported to a fuel fabrication facility where it can be
manufactured into reactor fuel (NRC 2007).

NRC has issued licenses for facilities to enrich uranium in the U.S. via gas centrifuge
processing, and two such facilities are currently under construction (NRC 2008). In this
process, centrifugal force generated in a rotating cylinder containing UFe gas separates the
lighter from the heavier uranium isotopes. A series (or "cascade") of centrifuges repeatedly
spins the products of the previous step, resulting in a progressively greater concentration of U235
(NRC 2008).

Laser enrichment is another technology that can be used to enrich uranium for use as nuclear
fuel, but it is a more difficult process, though more efficient. This technology is still in
development, and it may be available in the future in the U.S. (NRC 2008).

The NRC is a regulatory agency and does not build or operate uranium enrichment facilities.
The NRC issues  licenses for these facilities. The NRC's regulatory authority under the Atomic
Energy Act does not extend to the energy efficiency of the facility. The NRC's implementing
regulations for NEPA are found in 10 CFR Part 51. If a license from NRC is requested to build a
new uranium enrichment facility, an appropriate NEPA assessment would be prepared, including
an EIS subject to EPA review and comment. Since the industrial processes described above have
high energy demands, both the construction and operation of the facility would present numerous

opportunities to incorporate energy efficiency principles into the proposed action. Many review
considerations identified in other sections of this document could be relevant, including the
following:

•    Procurement of appliances and equipment (Section 5.1)
•    Facility siting (Section 5.2)
•    Construction and buildings (Sections 5.3 and 5.4)
•    Laboratories (Section 5.7)
•    Industrial facilities (Section 5.8)

Power Plants

Thousands of generators in the U.S. produce electrical power for public consumption using
sources that include coal, petroleum, natural gas, other gases, nuclear, conventional
hydroelectric, wind, solar thermal and photovoltaic, wood and wood-derived fuels, geothermal,
other biomass, pumped storage, and other sources (such as batteries, chemicals, hydrogen, pitch,
purchased steam, sulfur, tire-derived fuels, and miscellaneous technologies). New sources are
added frequently, while others are retired. EISs may be prepared when a federal agency is
involved in funding or licensing a power plant.

Many review considerations identified in other sections of this document could be relevant,
depending  on the details of the proposed action, including the following:

•    Procurement of appliances and equipment (Section 5.1)
•    Facility siting (Section 5.2)
•    Construction and buildings (Sections 5.3 and 5.4)
•    Laboratories (Section 5.7)
•    Industrial facilities (Section 5.8)

In addition, power plant and supporting operations design presents many opportunities to
conserve water resources and increase energy efficiency. Cooling  systems for thermal
(conventional and nuclear) power plants, in particular, can have large water requirements,
amenable to implementation of water conservation measures. EPA reviewers identify language
indicating that water consumption has been quantified, and whether inclusion of conservation
measures has been considered.

For coal powered plants, the beneficial reuse of fly-ash and other coal combustion products can
improve energy efficiency. See 5.11 .b for information on the EPA/DOE/USDA Coal
Combustion Products  Partnership.

Several states also require that the energy resource planning used to determine the need for a new
power plant fully integrate cost-effective energy efficiency. By integrating energy efficiency
resources, the need for a power plant may be deferred.

Nuclear Power Plants

The NRC is a regulatory agency and does not build or operate nuclear power plants.  The NRC
issues permits and licenses for these facilities.  The NRC's regulatory authority under the Atomic
Energy Act does not extend to the energy efficiency of the facility. The Nuclear Regulatory
Commission (NRC) has specific guidance (NUREG-1555, http://www.nrc.gov/reading-rm/doc-
collections/nuregs/staff/srl555/srl555.pdf) for its staff regarding energy reviews for EISs.
NUREG-1555 contains environmental standard review plans comprised of a series of
instructions developed for NRC staff to use when conducting environmental reviews of
applications related to nuclear power plants. The efficiency, conservation and demand side
management discussed in the ESRP refers to the service area to which the applicant will be
supplying electricity. It does not refer to the efficiency of the nuclear power plant or the
buildings associated with the nuclear power plant.

Chapter 8, Need for Power, Sections 8.2.1- "Power and Energy Requirements" and 8.2.2-
"Factors Affecting Growth of Demand" specifically addresses energy efficiency. They direct the
staff to analyze and evaluate the historic (15 years preceding the date of the application) and
projected (3rd year of commercial operation of proposed units) electricity consumption and
peakload demands in the relevant service  area  or market. In performing the review, NRC may
rely on the analysis in the applicant's environmental report and/or State or regional authorities'
or Independent System Operators' analyses concerning the need for power and energy supply
alternatives after ensuring that the analysis of the need for power and alternatives is reasonable
and meets high quality standards. Many of the applicants for a license for a nuclear power plant
are regulated utilities and as  such their State public service commission may have required the
utility to implement conservation, efficiency measures and demand side management. The NRC
considers these measures in its analysis of the "need for  power" in the EIS.

According to this guidance, a qualitative assessment as to the effectiveness of energy efficiency
improvements in the last several years given industry restructuring, price changes, recession, and
weather should be included.  Successful efforts undertaken within the relevant region to promote
energy efficiency on the part of customers and with respect to internal use of power transmission
and distribution efficiency and demand side management should also be included.

The guidance states that the EIS should include the following:
    1.  public disclosure of the applicant's forecasts of peakload and electrical energy demand
       and
    2.  presentation of the staffs evaluation regarding the  completeness and adequacy of these
       forecasts.

Chapter 9, "Alternatives to the Proposed Action", Section  9.2.1 "Alternatives Not Requiring
New Generating Capacity" also includes a brief discussion on  energy efficiency. The discussion
is in terms of an analysis of conservation as  an alternative to construction of the proposed plant.
This discussion indicates that the EIS should include the bases  for rejecting or accepting the
alternative and supporting data such as:
    1.  the amount of (or lack of) excess generating capacity available for purchase,

   2.  the plants within the regional system, if any, available for reactivation or extended
       service life and their operating costs and availability factors, and
   3.  the effects of conservation on reducing the need for electrical generating capacity.

Dredging

Options for improving the energy efficiency of dredging are not well-documented. One option
that was identified, however, is to reduce the water content of the dredged material, which
reduces the amount of dredge waste. This reduces the amount of energy needed to process
dredged material, improving the energy efficiency of the dredge removal process (Black Sea
Coast Association 2001).

Equipment choices,  such as newer dredge pump designs, can also improve the energy efficiency
of dredging.

Water and Wastewater Infrastructure

Energy efficiency and water conservation can be increased by improvements in several aspects
of water and wastewater systems (Alliance to Save Energy (2007),  as follows:

•    Pumps: efficient pumps of the right size (trim impellers  when pumps already in place are
     too large), variable speed drives, maintenance, re-wind pump motors when insufficient
     funds to replace them.
•    Leaks: detect and repair, manage network pressure, measure minimum night flow to gauge
     leakiness of system.
•    System automation.
•    Metering and monitoring: process for regular system monitoring, water meters,
     performance metrics, monitor the pump system (such as valves, flow, pressure, rotating
     speed, energy used, volume pumped, and velocity in the main headers).

EPA (2008a) stated that the water sector's energy efficiency can be supported by the Agency by
"promoting benchmarking by utilities so that they better understand how their actions yield
results; promoting use of energy efficient products/practices; and evaluating the life cycle energy
costs associated with proposed projects so that alternatives can be appropriately considered."
Examples include:

•    Designing and implementing an environmental management system (EMS).  An EMS is a
     set of processes and practices that enable an organization to reduce its environmental
     impacts and increase its operating efficiency. More information can be found on the EPA
     website: http://www.epa.gov/ems/.
•    Use of the ENERGY STAR Portfolio Manager tool to track and assess energy and water
     consumption; this tool includes drinking water and wastewater treatment facilities in its
     suite of facilities.
•    Performing an energy audit. Information and examples  can be found at the EPA Region 9
     website: http://www.epa.gov/region09/waterinfrastructure/audit.html.  Links to energy

                                         Energy Efficiency Reference for Environmental Reviewers
     efficient technologies for water and wastewater infrastructure can be found at:
     http://www.epa.gov/region09/waterinfrastructure/technology.html.
•    Use of CHP systems in waste water treatment facilities that have anaerobic digesters.
     Biogas flow from these digesters can be used in a CHP system as "free" fuel to generate
     reliable electricity and power for the facility (EPA 2008b).
•    Use of alternative energy sources for utility operations, including solar cells, fuel cells, and
     wind turbines.
•    Use of EPA technical assistance in asset management
     (http://www.epa.gov/OWM/assetmanage/index.htm).  Asset management can be defined as
     managing infrastructure capital assets to minimize the total cost of owning and operating
     them, while delivering the service levels customer's desire.  It is successfully practiced in
     urban centers and large and small sewer collection systems to improve operational,
     environmental, and financial performance (includes such measures as modified flow and
     energy demand programs and software).

For new facilities and upgrades to existing facilities, design concepts to improve energy
efficiency include:
    •   Lay out the pipes first within the treatment facility so water is moved the shortest and
       most direct distances with the least amount of turns and bends.
    •   Reduce friction by using large diameter pipe.
    •   Remove solids at the beginning of treatment to reduce the need for extra energy to move
       the solids within the facility.
    •   Incorporate a drying process with the solids removal process to reduce extra energy
       needed to move the extra moisture content in the solids.
    •   Increase residence time for additional treatment instead of adding more aeration.
    •   Reduce hydraulic  head to reduce pumping capacity.
    •   Codigest biosolids and biowaste to reduce the volume of sludge trucked to a landfill.
    •   Consider using a high-density diffuser as opposed to an aeration system, which uses more
       energy.  The energy savings from the diffuser can offset the greater capital cost within 3
       to 5 years.
    •   Use more efficient single stage blowers that save power and require less space, saving
       building and operating costs.
    •   Use variable speed pumps and motors to match capacity with variable demand.
    •   Do not use materials that corrode and keep materials and structures such as ceilings,
       roofs, and walls away from treatment processes that emit vapors that are corrosive.
    •   Design system in multiple units that can be added or deleted to expand or contract
       treatment facility without the need to replace an entire component.
    •   Reduce the amount of chemicals required to treat and maintain treatment facilities by
       using biological or physical processes.
    •   Design systems and equipment so less items are needed, so there are fewer replacement
       parts.
    •   Design systems to reduce building height and amount of covers to save on materials,
       lighting, heating.

In 2008, EPA (2008c) published Ensuring a Sustainable Future: An Energy Management
Guidebook for Wastewater and Water Utilities. The introduction states that "If drinking water
and wastewater systems  reduce energy use by just 10% through cost-effective investments,
collectively they could save approximately $400 million and 5 billion kWh annually." This 113-
page guide offers tools, links, technology suggestions, and management strategies to assist
utilities at all points on the energy efficiency spectrum make improvements, using a "Plan-Do-
Check-Act"  approach that is cross-referenced to other programs including ENERGY STAR,
asset management, ISO 14001  environmental management systems, and the American National
Standards Institute's Management System for Energy. The guide sets out the steps that a facility
would take to understand their energy use and set reduction goals,  take actions, and make
progress on achieving energy reduction targets.

The Water Environment Research Foundation is coordinating a project funded by the Global
Water Research Coalition to develop "Energy Efficiency in the Water Industry: A Compendium
of Tools, Best Practices and Case Studies." When complete (projected for spring 2010), this
document should serve as a useful tool for EPA Section 309 reviewers of EISs for water and
wastewater infrastructure projects. Updates can be found at www.werf.org/operations.

Mining and Other Resource Extraction Projects

The Southwest Energy Efficiency Project (2003) identified a comprehensive set of possibilities
for improving energy efficiency in the mining sector, as follows:

•    Improving exploration techniques: minimize exploratory digging and drilling by deploying
     non-invasive technologies such as remote sensing and ground-based technologies;
     advanced techniques for assaying mineral content at exploratory sites to prioritize follow-
     up.
•    Raising the efficiency of the drilling, excavation, extraction,  and ventilation processes:
     using efficient and correctly sized  excavation motors and pumps; using insulated pipes  and
     pumps and fan/coil heat exchangers located in the mine itself for ventilation ("[t]he closed
     loop used to pipe chilled water takes advantage of gravity to  move water into and out of the
     mine, and water can contain 55 times more energy per unit of volume than can air.  In
     addition, it is simpler and more efficient to insulate pipe than ducts.")
•    Ore processing: use of correctly sized and properly maintained motors, along with
     adjustable speed drives for applications with varying load requirements; for smelting, use
     oxygen-fueled burners rather than  air-fueled burners to reduce energy use and emissions.

                                          5-152               EPA Publication No. 315-R-09-001

                                          Energy Efficiency Reference for Environmental Reviewers
DOE (2007) published case studies from the mining industry that demonstrate the savings
associated with improvements in mining, some of which are included in the list above:

•    mining fan system optimization;
•    retrofitting smelting applications from air-fuel to oxy-fuel burners;
•    modernizing an electrolysis system; and
•    optimizing pump systems.

EPA reviewers can look for inclusion of technologies such as these in the alternatives evaluated
in anEIS.

Electricity Transmission and Distribution

"The electric grid delivers electricity from points of generation to consumers, and the electricity
delivery network functions via two primary systems: the transmission system and the distribution
system. The transmission system delivers electricity from power plants to distribution
substations, while the distribution system delivers electricity from distribution substations to
consumers.  The grid also encompasses myriads of local area networks that use distributed
energy resources to serve local loads and/or to meet specific application requirements for remote
power, village or district power, premium power, and critical loads protection (DOE 2009b)."

Given the state of our electricity grid, EPA is likely to review EISs addressing the expansion
and/or modernization of our electricity grid over the coming years. Grid expansions are
expected to extend electricity transmission to new generators, particularly in the case of
renewable resources, such as wind, which are available in areas currently not served or
connected to the transmission grid.  Increases in electricity demand, particularly during  peak
hours of the day, is likely to lead to expansions in our transmission and distribution systems.
Demand-side options, including energy efficiency and demand response programs, may defer the
need for such expansions to load growth.

Title XIII of the Energy Independence and Security Act of 2007 (EISA) states, "It is the policy
of the United States to support the modernization of the Nation's electricity transmission and
distribution system to maintain a reliable and secure electricity infrastructure that can meet future
demand growth and to achieve each of the following, which together characterize a Smart Grid.

           1.  Increased use of digital information and controls technology to improve
              reliability, security, and efficiency of the electric grid;
           2.  Dynamic optimization of grid operations and resources,  with full cyber-security;
           3.  Deployment and integration of distributed resources and generation, including
              renewable resources;
           4.  Development and incorporation of demand response, demand-side resources, and
              energy efficiency resources;
           5.  Deployment of "smart" technologies (real-time, automated, interactive
              technologies that optimize the physical operation of appliances and consumer

              distribution automation;
          6.  Integration of "smart" appliances and consumer devices;
          7.  Deployment and integration of advanced electricity storage and peak-shaving
              technologies, including plug-in electric and hybrid electric vehicles, and thermal
              storage air conditioning;
          8.  Provision to consumers of timely information and control options;
          9.  Development of standards for communication and interoperability of appliances
              and equipment connected to the electric grid, including the infrastructure serving
              the grid; and
          10. Identification and lowering of unreasonable or unnecessary barriers to adoption of
              smart grid technologies, practices, and services."

EISA established the Federal Smart Grid Task Force
(http://www.oe.energy.gov/smartgrid_taskforce.htm) to coordinate smart grid activities across
the Federal Government. Task Force activities include coordinating security issues and
advancing interoperability  standards so that technologies across the grid can better communicate
with one another. The Task Force has also commissioned a report on understanding the potential
CC>2 benefits from smart gird technologies. It includes experts from several Federal agencies,
including DOE (Office of Electricity Delivery and Energy Reliability and Office of Energy
Efficiency and Renewable  Energy), FERC, Department of Commerce (DOC), EPA, Department
of Homeland Security (DHS), Department of Agriculture (USD A), Federal Communications
Commission (FCC), and DoD.

The DOE OE office has the lead role on federal efforts to modernize the electricity grid.  This
includes both the federal Smart Grid Task Force and a national Electricity Advisory Committee.
DOE also sponsors research and development on smart grid technologies, as well as grid
modernization strategy tools for industry and broad educational offerings for states, customers
and others.  The American Recovery and Reinvestment Act of 2009 (ARRA) provided
approximately $4.5B to smart grid investment projects and regional demonstration projects.
DOE is responsible for awarding these funds and reporting on the results. Based on DOE's
selections announced on October 27, 2009, ARRA smart grid investment grant program funding
is being considered in the following categories: advanced metering infrastructure, customer
systems, electricity distribution systems, electric transmission systems, equipment
manufacturers, and integrated and/or cross cutting systems.

At the federal level, FERC has authority over electricity rates and terms and conditions of
transmission and wholesale sales in interstate commerce.  FERC also has responsibility for
approving and enforcing mandatory reliability standards for the bulk power system and adopting
smart grid interoperability  standards for the interstate transmission of electric power
(http://www.ferc.gov/industries/electric/indus-act/smart-grid.asp).  It is important to highlight
that FERC has jurisdiction over hydropower projects but has no authority over the construction
or maintenance of power generating plants and has significant limited jurisdiction over
transmission line siting, electricity distribution systems, and retail sales.  The responsibility over
the construction and maintenance of power generating plants and transmission lines primarily
resides with the state Public Utility Commissions (PUC).  State PUCs also have authority over


                                         5-154                EPA Publication No. 315-R-09-001

electricity distribution systems and the rates paid and services received by retail customers.
Links to all the PUCs are located at http://www.naruc.org/.

Under EISA, the National Institute of Standards and Technology (NIST), (a non-regulatory
federal agency within DOC) has responsibility to coordinate development of interoperability
standards and protocols for a smart grid (http://www.nist.gov/smartgrid/). Interoperability
standards will help generators, transmission, distribution, consumer products, and buildings
communications to facilitate a desired action. For example, "smart" appliances and products
may tell consumers how much power they are using and at what cost, providing additional
information and feedback to help lower their power consumption and energy bills. In addition,
smart grid technologies may help the electricity system manage large penetration (higher than
20%) of renewable generation that provides varying levels of power throughout the day (DOE
2009c).

Efforts are also underway to engage states, consumers, environmental groups and others in the
deployment of the smart grid. For example, DOE  and EPA facilitate a Smart Grid Stakeholder
Group, which released a Perspective for Utilities and Others Implementing Smart Grids
document in September 2009. This document was developed to provide general guiding
principles for utilities and other smart grid project  developers as they begin to plan and
implement upgrades to their metering infrastructures, transmission and distribution networks.  It
is located at http://www.epa.gov/cleanenergy/documents/stakeholder roundtable sept09.pdf
Key findings include but are not limited to:

    •   More information on smart grid demonstrations and deployments is needed, particularly
       from the perspectives of utility regulators, consumers and those with expertise about the
       environmental impacts or benefits.
    •   Technology investment is important, but thorough evaluations and possibly the adoption
       of additional policies are needed to ensure that the potential environmental and consumer
       benefits from smart grid investments exceed the costs.
    •   Pioneers of smart grid deployments need to learn from each other and help to inform
       further technology and policy development.

309 Reviewers may be interested in a particular section of this report, "Smart Grid and Its Link
to The Environment."  It discusses both the environmental benefits and potential
disadvantages/concerns that may be affiliated with the smart grid. This stakeholder dialogue
revealed the following potential environmental benefits from a smart grid:

    1.  Reduced integration costs for variable renewable technologies and plug-in electric
       vehicles
    2.  Greater use of clean distributed general on  options by all consumers (such as solar
       rooftops)
    3.  Enhanced load control capabilities that can provide sustainable energy efficiency savings
       for utilities and therefore help to avoid new generation
    4.  Reduction in energy losses across the transmission and distribution grids

                                                                            March 2010
                                         Energy Efficiency Reference for Environmental Reviewers
Environmental participants' concerns about a smart grid included whether smart grid
technologies would enable greater use of diesel back-up generators or encourage a shift of
energy usage from peak load periods during the day to greater reliance on base load fossil plants
and their effect on total emissions. Further, smart grid technologies themselves use electricity
(computing, network equipment, sensors) and contribute to data center load. For these reasons,
in order to address this issue an EIS may include a utility's holistic approach to meeting emission
reduction goals that may rely on clean demand response (such as load curtailment), increased
deployment of various renewables, smart grid technologies that are themselves energy efficient,
data center energy efficiency efforts, and other measures.

The following are other issues that were highlighted in the report that 309 Reviewers may
consider while reviewing an EIS that addresses a smart grid:

    1.  What are the anticipated environmental benefits of the smart grid deployment and how
       will these be measured, including enabling greater penetration of renewable generation
       and peak and total energy use reductions.
   2.  Are any risks being shifted from the utility to customers, or within customer classes? In
       particular, will additional risks be transferred to environmental justice communities?
   3.  If upgrades are intended to reduce peak load, how much load will be avoided over what
       period? Are these savings being captured in energy and air planning?
   4.  How much consumer interaction is required?  Will  all customers, including
       environmental justice communities, have access to benefits?
          a.   Will customers have access to their energy use, price and bill information? What
              will be done with this information to help make it actionable for consumers to
              reduce their total energy use?
          b.  Will customers be required to purchase a new technology or service (such as grid-
              connected appliances, a home area network, or energy management system) in
              order to reduce their total energy bills? How will that purchase be incented
              through rates and other programs to address the additional market barriers?
          c.   Will all customers have access to the enabling technology? For example, will
              Internet connections be required in homes to obtain information feedback? Will
              information also be available to customers in low or no tech formats?
          d.  Has the utility performed any customer research to fully understand what different
              customers want and will respond to? How does this vary by different customer
              segments (i.e. low-income residential, commercial buildings with existing energy
              management systems, etc).
          e.   What is being done to ensure the utilities' smart grid technologies will be
              interoperable with available  technologies within homes and buildings?
   5.  Has the utility considered the broad environmental impacts as well as benefits from smart
       grid deployment? For instance, data storage associated with smart grid technology will
       undoubtedly increase.  Data storage centers are huge energy users. Has the utility
       evaluated the broad spectrum of savings offset by the potential increases of electric use
       from its smart grid additions?
   6.  Will building managers have access to consumption data and information to better
       manage energy use by ensuring that installed equipment are maintained and operating as
       designed to meet forecasted loads and to allow for changes in operational requirements?


                                          5-156               EPA Publication No. 315-R-09-001

                                          Energy Efficiency Reference for Environmental Reviewers
Another challenge is the integration of renewable energy into the existing grid where there is the
tendency of large-scale renewable energy facilities to be located far from population centers;
additional expense is required for property acquisition, transmission lines and road construction.
To overcome this challenge, one solution is to construct renewable energy projects on
brownfields, abandoned mines, federal Superfund sites, non-federal  Superfund sites, or other
disturbed areas. Many of these locations have transmission capacity on-site and/or may be closer
to population centers.  Another alternative which limits the need for new transmission is the
possibility of locating  solar facilities near substations, where only short-interconnections are
needed.

Smart Grid technology deployments may increase energy efficiency by reducing line losses and
controlling voltage levels on the electricity system and supporting greater energy efficiency and
clean distributed generation in homes, buildings and industry. The technologies alone will not
provide the end-use energy efficiency benefits directly. EPA reviewers may also look to
resources of the National Action Plan for Energy Efficiency (Section 4.2) for information on
policy and program  options to support achieving energy efficiency savings.  As smart grid
deployments are still under development, EPA reviewers can request that smart grid projects
share information on the energy savings realized through the investment.  This can help better
inform EPA on the efficiency opportunity for future reviews.

EPA reviewers may also consider whether federal actions related directly (siting of new
transmission lines and power plants) or programmatically to electricity transmission and
distribution have considered technologies and policies, including those considered Smart Grid,
that could help increase energy efficiency benefits from the investment. In the case of new long-
distance transmission lines, EPA reviewers may consider not only the line, but potential for
environmental effects  from the power generator that will now be generating power due to the
line.

Many review considerations identified in other sections of this document could be relevant,
depending on the details of the proposed action, including the following:

•    Procurement of appliances and equipment (Section 5.1)
•    Construction and buildings (Sections 5.3 and 5.4)
•    Laboratories (Section 5.7)
•    Industrial facilities (Section 5.8)

In a related matter, EPA entered into a Memorandum of Understanding (MOU) with the
Department of the Interior (DOI), USD A, DOC, DoD, DOE, the Advisory Council on Historic
Preservation,  CEQ, and FERC.  Its intent is to expedite the siting and construction of qualified
electric transmission infrastructure in the United States.  It also improves coordination among
project applicants, federal agencies, and states and tribes that are involved in the siting and
permitting process.  The MOU assigns the lead agency for NEPA and other  environmental
reviews.  It is located at:

Renewable energy and energy efficiency technologies are
closely related in that both seek to increase energy
sustainability and reduce pollution caused by energy use.
This chapter presents information on current and
developing renewable energy technologies and federal
renewable energy programs.  Section 309 reviewers can
use the information provided in this chapter to make
informed recommendations to federal agencies for
incorporating renewable energy technology in the actions,
decisions and operations of the Federal government (see      x	•
Section 5.11 Other Operations, for information on the related topic of electricity transmission
and distribution).

The figure below shows U.S. energy consumption by production type. In 2007, renewable
energy supplied about 7% of the nation's energy needs.  Hydroelectric and biomass together
provide 89% of the U.S. renewable energy supply.

As of 2007, the majority of renewable energy consumption (51%) was for the production of
electricity. Most of the remaining 49% of renewable energy consumed was biomass for industrial
applications (principally paper-making) by plants producing only heat and steam. Biomass is
also used for transportation fuels (ethanol) and to provide residential and commercial space
heating.

Several federal agencies have conducted comprehensive assessments evaluating the potential for
increased renewable energy development.  These reports can aid federal and military decision
makers in prioritizing activities that will increase the federal government's use of renewable
energy technologies. Reports include:

Renewable Energy Council. DSIRE tracks energy efficiency financial incentives and rules,
regulations and policies established by the federal government, state governments, larger local
governments and larger electric utilities.

The DOE EERE has renewable energy research and development partnership programs and
conducts research related to these renewable energies with the Solar Energy Technologies
Program, the Wind and Hydropower Technologies Program, the Geothermal Technologies
Program, and the Biomass Program. Information in the following sections is adapted from DOE

6.1 Solar Power

Solar power involves collecting energy from sunlight and converting it into heat, electricity or
supplemental lighting.  Solar technologies are broadly characterized as either passive or active
depending on the way they capture, convert and distribute sunlight.  Active solar techniques use
technology such as photovoltaic panels, pumps, and fans to convert sunlight into useful outputs.
Passive solar techniques include selecting materials with favorable thermal properties, designing
spaces that naturally circulate air, and referencing the position of a building to the sun.

Passive Solar Design
Passive solar design is the technology of
heating, cooling, and lighting a building
naturally with sunlight rather than with
mechanical systems. Basic design
principles are large south-facing windows
with proper overhangs, as well as tile,
brick, or other thermal mass material used
in flooring or walls to store the sun's heat
during the day and release it back into the
building at night or when the temperature
drops. Passive solar can also use energy
efficient materials, improved insulation,
airtight construction, natural landscaping,
and proper building orientation to take
advantage of the sun, shade, and wind.
Passive solar designs can include natural
ventilation for cooling (DOE 2009c).

Solar Water Heating

Solar water-heating systems use
collectors, generally mounted on a south-
facing roof, to heat either water or
nontoxic antifreeze that is circulated from
the collector to the water  storage tanks.
The heated water is then stored in a water
tank similar to one used in a conventional
gas or electric water-heating system.

Collectors heat water either "passively" or
"actively." Passive  solar water-heating
systems use natural convection or water
pressure to circulate water through a solar
collector to a storage tank. They have no
electric components that could break, a
Hybrid Solar Lighting Illuminates Energy
Savings for Government Facilities
http://wwwl.eere.energy.gov/femp/pdfs/tf hybridso
lar.pdf
Electric lighting is the greatest consumer of
electricity in U.S. commercial buildings and
generating this electricity by conventional power
plants is the building sector's most significant cause
of air pollution. Hybrid solar lighting provides a
new means of reducing energy consumption in
federal buildings while delivering benefits
associated with natural lighting.  The technology
could be particularly useful in the Sunbelt where
cooling is a significant source of energy use.

Hybrid solar lighting contributes to meeting the
requirements set by EPAct 2005 for federal
renewable energy consumption The technology was
originally developed for fluorescent lighting
applications but has been enhanced to work with
incandescent accent-lighting sources, such as the
parabolic aluminized reflector (PAR) lamps
commonly used in retail spaces. Commercial
building owners—specifically retailers—use the
low-efficiency PAR lamps because of their desirable
optical properties and positive impact on sales. Yet
the use of this inefficient lighting results in some
retailers' spending 55-70% of their energy budgets
on lighting and lighting-related energy costs.

Solar lighting can significantly reduce artificial
lighting requirements and energy costs in many
commercial and industrial buildings and in
institutional facilities Future R&D is aimed at
enhancing the performance and reliability of the
technology as well as extending the application of
the system to work with newly emerging solid-state
lighting sources.

feature that generally makes them more reliable, easier to maintain, and possibly longer lasting
than active systems. An active system uses an electric pump to circulate water or nontoxic
antifreeze through the system. Active systems are usually more expensive than passive systems,
but they are also more efficient. Active systems are easier to retrofit than passive systems
because their storage tanks do not need to be installed above or close to the collectors. In
addition, the moving water in the system will not freeze in cold climates. However, because
these systems use electricity, they will not function in a power outage. For this reason, many
active systems are now combined with a small solar-electric panel to power the pump.

The amount of hot water a solar water heater produces depends on the type and size of the
system, the amount of sun available at the site, proper installation, and the tilt angle and
orientation of the collectors (DOE 2009c).

Photovoltaics and Thin Film Technology
Photovoltaics are silicon-based devices that convert light into electricity. These devices are
grouped together into photovoltaic modules and either used to provide power for individual
structures or for large-scale grid-connected power generation. The larger photovoltaic
installations, called solar farms, can encompass numerous acres and many interconnected
photovoltaic modules. Because of this modularity, PV systems can be designed to meet any
electrical requirement, no matter
how large or how small. Thin-
film, a more recent development
in PV technology, uses
microscopically thin layers of
material deposited  onto a metal,
ceramic, semiconductor or
plastic base. Thin films of
photovoltaic material using
silicon, cadmium telluride and
other elements are used to make
solar panels and solar roof
shingles.

Concentrated Solar Power
Concentrated solar power is a solar thermal technique that uses reflective surfaces from
dish/engine systems, parabolic troughs, and central power towers that focus or concentrate the
sun's heat energy. This concentrated solar energy then drives a generator to produce electricity.
Concentrated solar power systems are divided into concentrated solar thermal and concentrated
photovoltaics. Concentrated solar power systems use lenses or mirrors and tracking systems to
focus a large area of sunlight into a small beam. The concentrated light is then used as heat or as
a heat source for a conventional power plant. Concentrated photovoltaics is a term used when
sunlight is concentrated onto photovoltaic surfaces for the purpose of direct electrical power
production. Compared to conventional flat panel solar cells, concentrated photovoltaics are
advantageous because the solar collector is less expensive than an equivalent area of solar cells.

The DOE Report to Congress, Concentrating Solar Power Commercial Application Study:
Reducing Water Consumption of Concentrating Solar Power Electricity Generation
(http://wwwl.eere.energy.gov/solar/pdfs/csp_water_study.pdf discusses potential methods to
reduce water consumption associated with concentrated solar power. The DOE fact sheet,
Concentrated Solar Power (http://wwwl.eere.energy.gov/solar/pdfs/43685.pdf), and Solar
Energy Technologies Program website provide more information on concentrated solar power.

Other solar heating technologies make use of low-temperature solar collectors that absorb the
sun's heat energy, allowing that heat to be used directly for water or space heating in residential,
commercial, and industrial buildings.  Solar lighting technologies rely on roof-mounted solar
concentrators to collect sunlight; this is then distributed through optical fibers to special lighting
fixtures in the building's interior that combine natural light with electric light to illuminate
interior spaces.

Distributed Generation

Solar power increases the potential for distributed energy generation. Distributed generation is
the production of energy  close to where it will be used, and power capacity usually ranges from 1
kilowatt to 5 megawatts (MW).  In contrast, central generation ranges from  10 to 1,000 MW and
supplies power to locations much farther away through transmission lines. Electric utilities often
tap into solar electricity for distributed applications, such as near substations or at the end of
overloaded distribution lines, to avoid or defer costly upgrades of transmission lines (DOE
2009d). Several reports published in February 2008 by NREL and DOE's EERE discuss the
mechanics and  challenges of distributed generation, including:

Solar energy capacity has more than doubled between
2000 and 2007, but still represents a very small part of
U.S. electricity generation (DOE 2009).  The DOE
EERE Solar Energy Technologies Program focuses on
developing cost-effective solar-energy technologies
that have the greatest potential for incorporation into
the market place. Along  with technology research and
development, the program works to remove non-
technical market barriers  (e.g., updating codes and

standards that are not applicable to new technologies, and improving interconnection agreements
among utilities and consumers). The program works with the National Renewable Energy
Laboratory, Sandia National Laboratories, Oak Ridge National Laboratory, and Brookhaven
National Laboratory to perform research support program management.  These laboratories are
organized into two virtual labs, the National Center for Photovoltaics (NCPV) and the SunLab
(for Concentrating Solar Power research).

There are four subprograms in the Solar Energy Technologies Program:  Photovoltaics,
Concentrating Solar Power, Systems Integration and Market Transformation. The Photovoltaics
subprogram funds PV technologies that have potential for significant advances in solar energy
efficiency.  The Concentrating Solar Power subprogram pursues research and development
activities in concentrating solar power to lower technology and manufacturing costs, increase
conversion efficiencies, and improve the reliability of components and systems.  The Systems
Integration subprogram focuses on reducing the regulatory, technical, and economic barriers to
integrate solar electricity into the electric grid. The Market Transformation subprogram works
with external partners to address non-R&D issues that are barriers to the widespread adoption of
solar technologies. Through this subprogram the DOE provides financial and technical
assistance,  information, and training related to solar technology.  The program also presents case
studies (e.g., http://www 1.eere.energy.gov/solar/cs_ca_substation.html) of successful solar
power implementation. More information on the program can be found at:
http ://wwwl. eere. energy, gov/solar/.
6.2 Wind Power

Wind power is the conversion of wind energy into a useful form, such as electricity, using wind
machines and turbines. Wind machines can be large individual structures with a small number of
sizable blades, or numerous smaller structures with many relatively tiny blades.  Specially-
designed blades are constructed to capture as much
wind as possible; this turns a drive shaft connected to a
turbine, generating electricity.  Modern wind turbines
fall into two basic groups: the horizontal-axis and the
vertical-axis design (DOE 2009e).
Larger turbines are grouped together into wind farms,
which provide bulk power to the electrical grid.
Utility-scale turbines range in size from 100 kilowatts
to as large as several megawatts. Single small turbines,
below 100 kilowatts, are used for homes,
telecommunications dishes, or water pumping. Utility
companies increasingly buy back surplus electricity
produced by small domestic turbines. Wind energy is
one of the lowest-priced renewable energy
technologies available today, costing between 4 and 6
cents per kilowatt-hour (DOE 2009e).

Electricity generated from wind power can be highly variable at several different timescales:
from hour to hour, daily, and seasonally. Annual variation also exists, but is not as significant.
Because instantaneous electrical generation and consumption must remain in balance to maintain
grid stability, this variability can present substantial challenges to incorporating large amounts of
wind power into a grid system. In particular geographic regions, peak wind speeds may not
coincide with peak demand for electrical power.  In California and  Texas, for example, hot days
in summer may have low wind speed and high electrical demand due to air conditioning.

Proper selection of a wind turbine site is critical to economic development of wind power. Aside
from the availability of wind itself, other factors  include the availability of transmission lines,
value of energy to be produced, cost of land acquisition, land use considerations, and
environmental impact of construction and operations. Although wind power plants have fewer
impacts on the environment compared to conventional power plants, impacts include noise
produced by the rotor blades, aesthetic (visual) impacts, and danger to migratory birds from the
spinning blades. Many potential sites for wind farms are far from  demand centers, requiring
substantially more money to construct new transmission lines and  substations.

                                  Development
Offshore winds tend to
flow at higher speeds
than onshore winds, thus
allowing turbines at
offshore locations to
produce more electricity.
Because the potential
energy produced from
the wind is directly
proportional to the cube
of the wind speed,
increased wind  speeds of
only a few miles per
hour can produce a
significantly larger
amount of electricity.
Much of this potential
energy is near major
population (and energy
load) centers where energy costs are high and land-based wind development opportunities are
limited (MMS 2009).  For this reason, interest in wind project located off the U.S. coast is
increasing.

In offshore facilities, undersea collection cables connect multiple turbines in the wind facility
and transport the electricity from them to a transformer where the combined electricity is
converted to a high voltage for transmission via undersea cables to a substation. There the
electricity is connected to the onshore electricity grid (MMS 2009).

Offshore turbines have technical needs not required of onshore turbines due to the more
demanding climatic environmental exposure offshore. U.S. waters are generally deeper than
those on the European coast where offshore wind projects are more common, and will require
new technology. Off-shore locations also have higher construction costs, but may offset these
costs with higher annual power generation, thereby reducing the cost of energy produced. The
National Renewable Energy Laboratory (NREL) published two recent reports on offshore wind
power potential, Future for Offshore Wind Energy in the United States in June 2004
(http://www.nrel.gov/docs/fy04osti/36313.pdf) and an April 2009 Outer Continental Shelf report
(http://www.doi.gov/ocs/).  The October 2007 MMS OCS Alternative Energy and
Alternate Use Programmatic EIS also contains information on offshore wind  energy
development (http://ocsenergy.anl.gov/guide/wind/index.cfm).

With a current annual growth rate of 30% to 40%, the nation's wind energy capacity increased
from 2,500 MW in 1996 to more than 21,000 MW at the end of 2008. However, wind energy
still comprises less than 2% of U.S. energy generation (DOE 2009e).

6.3 Geothermal Power

Geothermal power comes from energy generated by heat stored in the earth.  Geothermal energy
is available 24 hours a day, 365 days a year. Geothermal power plants have average availabilities
of 90% or higher, compared to about 75% for coal plants. In the U.S., most geothermal
reservoirs are located in the western states, Alaska, and Hawaii. Geothermal resources range
from shallow ground to hot water and rock several miles below the Earth's surface, and even
further down to the extremely hot molten rock called magma (DOE 2009b). Wells over a mile
deep can be drilled into underground reservoirs to tap steam and very hot water that can be
brought to the surface for use in a variety of applications. Geothermal systems are recognized as
one of the most efficient heating and cooling systems available. Geothermal technologies
include collecting energy through heat pumps, hot dry rock processes, and direct heating.
In most areas, the upper 10 feet of Earth's
surface maintains a nearly constant
temperature between 50 and 60°F. A
geothermal heat pump system consists of
pipes buried in the shallow ground near a
building. In winter, heat from the relatively
warmer ground is collected in the pipes and
brought into building, while in summer hot
air from the building is pulled out into the
relatively cooler ground. Heat removed
during the summer can be used as no-cost
energy to heat water (DOE 2009b).

The initial cost of installing a geothermal
heat pump system can be  two to three times
that of a conventional heating system in
most residential applications, new
construction or existing buildings. There are
four basic types of heat pump  systems. Three

of these—horizontal, vertical, and pond/lake—are closed-loop systems. The fourth type of
system is the open-loop option. Which one of these is best depends on the climate, soil
conditions, available land, and local installation costs at the site.

More information on heat pump systems can be found at:
http://www.energysavers.gov/vour home/space  heating  cooling/index.cfm/mvtopic=12650.

Hot dry rock technology is a type of geothermal power production that uses the very high
temperatures found in rocks a few kilometers below the surface. By pumping high pressure water
down a borehole, the water travels through fractures in the rock and absorbs heat energy and is
subsequently forced out of a second borehole as very hot water. This water is then used to run a
turbine and generate electricity. The cooled water is injected back into the ground to heat up
again in a closed loop. Higher permeability of the rock is important, as it allows for the greater
energy production. Although natural fractures may provide adequate flow rates, systems can be
enhanced through hydraulic stimulation which involves pumping cold water with acid additives
into the rock to open the fractures.  Three types of geothermal power plants are operating today:

•    Dry steam plants, which directly use geothermal steam to turn turbines;

•    Flash steam plants, which pull deep, high-pressure hot water into lower-pressure tanks and
     use the resulting flashed steam to drive turbines; and

•    Binary-cycle plants, which pass moderately hot geothermal water by a secondary fluid with
     a much lower boiling point than water. This causes  the secondary fluid to flash to vapor,
     which then drives the turbines (DOE 2009b).

In direct geothermal heating, hot water near Earth's surface is piped directly into facilities and
used to heat buildings, grow plants in greenhouses, aquaculture, crop drying and a variety of
other tasks. Some cities pipe the hot water under roads and sidewalks to melt snow. District
heating applications use networks of piped hot water to heat buildings in whole communities
(DOE 2009b). Direct-use systems typically include three components:

•    A production facility — usually a well — to bring the hot water to the surface;
     A mechanical system — piping, heat
     exchanger, controls — to deliver the heat to
     the space or process; and
     A disposal system — injection well or storage
     pond — to receive the cooled geothermal
     fluid.

research on enhanced geothermal systems (EGS), which are engineered reservoirs created to
produce energy from geothermal resources that are otherwise not economical due to lack of
water and/or permeability. EGS technology has the potential for accessing the Earth's vast
resources of heat located at depth.  The program provides technical information on geothermal
heat, including geothermal resource maps (http://wwwl.eere.energy.gov/geothermal/maps.html),

(http://wwwl.eere.energv.gov/geothermal/publications.html) and software programs that model

6.4 Biomass

Biomass power is solar energy stored in organic matter. Sources of biomass energy include
agricultural and forestry residues, manure, municipal solid wastes, industrial wastes, and
terrestrial and aquatic crops grown solely for energy purposes. Biomass can be grown from
numerous types of plants, including miscanthus, switchgrass, hemp, corn, poplar, willow,
sorghum, sugarcane, and a variety of tree species, ranging from eucalyptus to oil palm (DOE
2009a).

                                                                               Distribution
Biomass resources are
used to generate
electricity and power,
and to produce liquid
transportation fuels, such
as ethanol and biodiesel.
There are generally two
ways to release  the
energy stored in biomass:
burning and
fermentation. Biomass
can be burned as a direct
heat source, or to heat
water and create steam to
power turbines which
generate electricity. Burning biomass to produce energy can circumvent waste management
problems by removing it from the waste stream. Burning biomass does generate carbon dioxide
and paniculate matter. However, biomass energy recycles carbon dioxide during the plant
photosynthesis process (DOE 2009a).

Biomass can also be fermented and made into liquid fuels, which are easily transportable. Many
car manufacturers are now producing flexible-fuel vehicles, which can safely run on blends of
ethanol, biodiesel and gasoline. Biologically produced alcohols, most commonly ethanol, and
less commonly  propanol and butanol, are produced by the action of microorganisms and
enzymes through the fermentation of sugars or starches or cellulose.  The distillation process
requires significant energy input for heat, which often comes from the burning of natural gas, as

                                         Energy Efficiency Reference for Environmental Reviewers
well as tremendous amounts of water. The burning of biomass itself can be used to increase
biomass sustainability (and reduce lifecycle CC>2 emissions), albeit with the accompanying
carbon dioxide and paniculate matter.

The burning and fermentation processes create co-products that can be used for other purposes,
such as ash for use in construction material, and dried distiller grains, corn gluten feed, corn oil
and other ingredients that can be used in plastics and chemicals. The generation and use of these
co-products help offset some of the energy-intensive nature of producing energy from biomass
(DOE 2009a).

EISA 2007 revises the Renewable Fuel Standard (RFS) for transportation fuels, originally
created under the Energy Policy Act of 2005. The Act seeks to increase the supply of biofuel by
requiring fuel producers  to use in the fuel mix a progressively increasing amount of biofuel,
culminating in at least 36 billion gallons of biofuel by 2022. Within these total volumes, new
volume standards are also created for cellulosic biofuel, biomass-based diesel, and other
advanced biofuel. EISA also includes new definitions and criteria for both renewable fuels and
the feedstocks used to produce them, including new lifecycle greenhouse gas (GHG) emission
thresholds for renewable fuels. EISA requires a 50% reduction in lifecycle GHG emissions for
fuels to be classified as biomass-based diesel or advanced biofuel, and a 60%  reduction in order
to be classified as cellulosic biofuel. EISA also  provides some limited flexibility for EPA to
adjust these GHG percentage thresholds downward by up to 10 percent under certain
circumstances. EPA issued a proposed rule on May 19, 2009 to implement these changes to the
RFS program, and is now working on a final rule. Additional details can be found at:
http://www.epa.gov/otaq/renewablefuels/index.htm

Biomass Program

The DOE Biomass Program partners with industry, academia and the national laboratories to
conduct research, development and demonstration projects on biomass feedstocks and
conversion technologies.  Two major focuses of the  program are ensuring that cellulosic ethanol
is cost competitive by 2012, and developing infrastructure and opportunities to bring biobased
fuels and products to market. Figure 6-1  shows projected U.S. biofuel sources.

The NREL has developed (with EPA Region 6 funding) a new biomass assessment tool.  While
it does not take the place of an on-the-ground detailed assessment, it can serve as an initial
screening tool to identify and evaluate sites for potential sources of biomass. It is a mapping
application that allows users to explore the potential of biomass-to-power conversions at
different locations and scales. It also allows for visualization and analysis of biomass resources
on a local basis. This tool is located at: http://rpm.nrel.gov/biopower/biopower/launch.

The 309 Reviewer should be aware that unlike oil and gas, the U.S. does not have a biomass fuel
commodity market.  For this reason, each biomass project would have to locate and/or acquire its
own supply of quality fuel.

6.5 Hydropower

Hydropower is derived from the force or energy of moving water. Today, the largest use of
hydropower is for the creation of hydroelectricity, currently the leading renewable energy source
used by electric utilities to generate electric power. Conventional hydropower is a key
component of the U.S. energy portfolio, representing approximately 7% of total U.S. electricity
generation and between 71-75% of U.S. renewable energy electricity generation (DOE 2009f,
EIA 2009b). There are significant opportunities to increase the nation's incremental
hydroelectric generation, to quantify and maximize the ancillary benefits to the U.S. electric grid,
and to improve the environmental performance of the U.S. hydroelectric industry.

There are three types of hydropower facilities: impoundment, diversion, and pumped storage.
The most common type of hydroelectric power plant is an impoundment facility.  An
impoundment facility, typically a large hydropower system, uses a dam to store river water in a
reservoir. Water released from the reservoir flows through a turbine, spinning it, which in turn
activates a generator to produce electricity. The water may be released either to meet changing
electricity needs or to maintain a constant reservoir level (DOE 2009e). There are not many
locations in the United States where dam installation is currently feasible, as many of the best
locations have already been acquired and built upon. In addition, the potential environmental
impacts to riverine systems associated with dam installation render many projects infeasible.

In a diversion hydroelectric facility, sometimes called run-of-river, a portion of a river is
channeled through a canal or penstock. A diversion facility may not require the use of a dam.
When the demand for electricity is low, a pumped storage facility stores energy by pumping
water from a lower reservoir to an upper reservoir. During periods of high electrical demand, the
water is released back to the lower reservoir to generate electricity.

Generating electricity using water has several advantages, including: 1) low cost, 2) little air
pollution compared with fossil fuel plants, and 3) limited thermal pollution compared with
nuclear plants. Like other energy sources, the use of water for generation also has limitations,
including environmental impacts caused by damming rivers and streams (EIA 2009c). Current
DOE research focuses on reducing the environmental impacts of hydropower facilities through
improved design of turbines in existing facilities.

Hydrokinetic Technologies

DOE research also focuses on new marine and hydrokinetic technologies - technologies capable
of generating electricity from waves, tidal, ocean, and river currents, and ocean thermal
energy/temperature gradients. Tidal power converts the energy of tides into electricity. Because
tides are caused by the forces related to the gravitational interaction with the moon, the sun and
the Earth's rotation, tidal power is predictable and practically  inexhaustible.  Tidal power can be
classified into two main types: kinetic and potential.  Tidal stream systems  make use of the
kinetic energy of moving water to power turbines, in a similar way to windmills that use moving
air. Some tidal stream systems use propellers or aerofoils, while others involve placing obstacles
in rivers in order to cause the formation of vortices which can then be tapped for energy. The
higher density of water means that a single generator can provide significant power at low tidal
flow velocities when compared to wind velocities.

Potential energy can be tapped by barrages (structures built across rivers and estuaries to manage
water) by taking advantage of the difference in water height between high and low tides.
Turbines installed in the barrage wall generate power as water flows in and  out of the estuary
basin, bay, or river.

Wave power is the transport of energy by ocean surface waves.  Waves are generated by wind
passing over the sea, and there is an energy transfer from the wind to the most energetic waves.
Devices can be used to take advantage of the wave swells: the rising and falling of the waves
can move a buoy-like structure, creating mechanical energy which is converted into electricity
and transmitted to shore over a submerged transmission line.  Other wave power devices consist
of a single piston pump attached to the sea floor, with a float tethered to the piston. Waves cause
the float to rise and fall, generating pressurized water, which is piped to an onshore facility to
drive hydraulic generators or run reverse osmosis desalination.

The U.S. market for marine and hydrokinetic energy is still in the early stages of development,
with a few technologies ready for demonstration or deployment. These technologies can be
deployed near densely populated load centers as well as for remote power applications.

Renewable Energy Development on the Outer Continental Shelf

In May 2009, the Federal Energy Regulatory Commission (FERC) and the U.S. Department of
Interior, Minerals Management Service (MMS) signed a Memorandum of Understanding (MOU)
regarding renewable energy development activities on the Outer Continental Shelf, including
hydrokinetic sources such as wave, tidal and ocean current. According the MOU:

    •   "MMS has exclusive jurisdiction with regard to the production, transportation or
       transmission of energy from non-hydrokinetic renewable energy projects including wind
       and solar. MMS also has jurisdiction to issue leases, easements and rights-of-way
       regarding Outer Continental Shelf lands for hydrokinetic projects. MMS will conduct any
       necessary environmental reviews, including those under the National Environmental
       Policy Act, related to those actions.
    •   FERC has exclusive jurisdiction to issue licenses and exemptions from licensing for the
       construction and operation of hydrokinetic projects on the Outer Continental Shelf and
       will conduct any necessary analyses, including those under the National Environmental
       Policy Act related to those actions. FERC's licensing process will involve relevant federal
       land and resource agencies including DOI.
    •   FERC will not issue a license or exemption for an Outer Continental  Shelf hydrokinetic
       project until the applicant first obtained a lease, easement or right-of-way from MMS for
       the site. FERC will not issue preliminary permits for hydrokinetic projects on the Outer
       Continental Shelf. In all leases, easements and rights-of-way for hydrokinetic projects,
       MMS will require that construction and operation cannot begin without a license or
       exemption from FERC, except when FERC notifies MMS that a license or exemption is
       not required (FERC 2009)."

The MOU also states that, "at its discretion, FERC may choose to become a  cooperating agency
with MMS in the latter's preparation of an environmental document for the lease, easement and
right-of-way for any Outer Continental  Shelf hydrokinetic project. Likewise, MMS may choose
to be a cooperating agency with FERC in the preparation of FERC's environmental documents
for the license or exemption of any Outer Continental Shelf hydrokinetic project (FERC 2009)."

The agencies also will coordinate to ensure that any licenses or exemptions issued by FERC and
all operations regulated by FERC, with respect to a lease, easement or right-of-way, are
consistent with the provisions of the Outer Continental Shelf Lands Act, the  Federal Power Act
and other applicable laws (FERC 2009). A copy of the MOU can be accessed at:

Wind and Hydropower Technologies Program

The mission of DOE's Wind and Hydropower Technologies Program is to conduct research and
development that will improve the technical, societal, and environmental benefits of hydropower
and provide cost-competitive technologies that enable the development of new and incremental
hydropower capacity.  Three of DOE's National Laboratories with experience in hydropower
issues provide technical support to the Program: Idaho National Laboratory (INL), Oak Ridge
                                          6-17                EPA Publication No. 315-R-09-001

National Laboratory (ORNL), and Pacific Northwest National Laboratory (PNNL). The lead
laboratory for engineering and program management support is INL. ORNL is the lead
laboratory for environmental and computational support. PNNL is involved in biological testing
and technology development studies, taking advantage of their experience with fish and test
facilities. A combination of industry, universities, and federal facilities conduct research
activities for the Hydropower Program. More information can be found at:
http://wwwl.eere.energy.gov/windandhydro/about.html and http://hydropower.id.doe.gov/.

In 2008, DOE, through the Water Power Program (a subprogram within DOE's Wind and
Hydropower Technologies Program), initiated advanced water power activities to research, test,
and develop innovative technologies capable of generating renewable, environmentally
responsible, and cost-effective electricity from water. These include marine and hydrokinetic
technologies, a new suite of renewable technologies that harness the energy from untapped wave,
tidal, current and ocean thermal resources.

The Water Program's activities with marine and hydrokinetic technologies include:

   •   Research and development funding for components and devices to optimize these
       technologies and help industry reduce costs and technical risks. In 2008, the program
       initiated the development of two new National Marine Renewable Energy Centers, and
       began technology characterization efforts that included the development of a marine and
       hydrokinetic technology and project database (http://www.eere.energy.gov/windand
       hydro/hydrokinetic/default.aspx),  which includes a technology glossary.
   •   Higher-resolution resource assessments to quantify and validate estimates of extractable
       energy quantity by location. Results from assessments will improve the quality of device
       and component testing by providing fundamental resource characteristic data and fill
       essential information gaps needed to reduce technical and project  risk  for  the investment
       community.
   •   Environmental effects studies to better assess potential impacts that hinder technology
       deployment, to aid the regulatory  process, and to reduce project development costs.

In addition, the Water Power Program works to develop technologies and processes to improve
the efficiency,  flexibility,  and environmental performance of hydroelectric generation. The
Water Power Program's activities with conventional hydropower include:

   •   Assessing the current state of the U.S. hydroelectric infrastructure and identifying
       opportunities for increased and more valuable generation. This includes increasing
       incremental generation through efficiency and capacity gain at existing power stations,
       placement of power stations at existing non-powered dams and in constructed waterways
       such as canals, and supporting the development of the small hydropower industry.
   •   Developing and deploying technologies, including pumped storage, that increase stability
       and operational flexibility of the U.S. electric grid and support the integration of variable
       renewable energy resources.
   •   Addressing environmental impacts through the development of new technologies and
       methods to improve environmental performance, which will mitigate such impacts as fish
       passage, water quality in reservoirs and downstream from dams, and altered flow regimes

       to Congress on the Environmental Effects of Marine and Hydrokinetic Energy Projects in
       December 2008, with the final report scheduled for publication in 2009. The report,
       prepared pursuant to EISA 2007, describes options to mitigate and prevent adverse
       environmental impacts from marine and hydrokinetic energy technologies
       (http://www.lawofrenewableenergv.com/2008/12/articles/renewable/doe-issues-draft-

6.6 Benefits and Limitations

There are substantial benefits to pursuing renewable energy technologies:  a relatively unlimited
supply, with little greenhouse gas or particulate matter generation. Renewable energy would also
help reduce the nation's dependence on foreign oil, protect against rising utility rates, reduce
operating costs, and provide jobs.  There are some technical, economic, operational, and regional
concerns regarding renewable energy, which are summarized in Table 6-3.
