Environmental Impacts of Airport Operations,
Maintenance, and Expansion
Funding authorization for Federal Aviation Administration (FAA) programs set
forth in the Vision 100 — Century of Aviation Reauthorization Act (P.L. 108-176,
hereinafter referred to as “Vision 100”) expired at the end of FY2007. During the
current reauthorization process, methods to address the environmental impacts
associated with airport operations and expansion are being debated. This issue is
important to various stakeholders, particularly those whose health, property values,
and quality of life may be affected by such impacts. The concerns of community
members and local, state, and tribal agencies regarding environmental impacts have
led to the delay and cancellation of some airport expansion projects.
To address these concerns, airports may be required to implement projects that
would minimize the environmental impacts of their operations. Some of these
projects qualify for federal funding. For example, in its FY2008 budget, the FAA
requested $354 million to meet its “Environmental Stewardship” goals. Projects
funded under this category address the environmental impacts of airports, primarily
to abate airport noise (e.g., soundproofing homes or purchasing noise barriers).
Among other uses, funds may be spent on projects to minimize water quality impacts
(e.g., funding projects that would control the discharge of deicing chemicals) and to
reduce airport-controllable air emissions (e.g., purchasing alternative fuel vehicles
to replace the airport’s ground services equipment). Funds also are authorized for
researching new aircraft technology that would reduce noise and air emissions.
The anticipated growth in air travel has heightened the significance and
complexity of some environmental regulatory issues. Also, several new requirements
are expected to affect airport operations (in terms of procedural changes and potential
investment in infrastructure). The most significant issues include changes to
Environmental Protection Agency (EPA) standards applicable to deicing operations
and oil spill prevention procedures, as well as state and local agency directives to
monitor and control air pollution, particularly toxic air pollutants.
The FAA has proposed legislation to reauthorize FAA funding (H.R. 1356 and
S. 1076, the Next Generation Air Transportation System Financing Reform Act of

2007, introduced by request). On May 3, 2007, the Senate reported its own bill (S.

1300, the Aviation Investment and Modernization Act of 2007). On September 20,

2007, the House passed its version (H.R. 2881, the FAA Reauthorization Act of

2007). The bills include provisions that would fund environment-related research;

fund grant programs to mitigate environmental impacts; fund grant programs to help
airports with environmental regulatory compliance; and amend existing noise
To better understand the need for funding for environment-related airport
projects, this report provides an overview of noise, water quality, and air quality
issues associated with airport operations. Also discussed are the environmental
review requirements of the National Environmental Policy Act of 1969 (NEPA) and
the environmental provisions in proposed legislation to reauthorize FAA programs.

Environmental Impacts of
Airport Operations, Maintenance,
and Expansion
The operation of an airport involves many activities that can affect the
environment. In addition to potential impacts to local air and water quality, aircraft
noise levels may affect property values or the quality of life of residents in nearby
communities. Certain activities or projects to address airport environmental impacts
may qualify for federal funding.1 For example, in its FY2008 budget, the Federal
Aviation Administration (FAA) requested $354 million to meet the agency’s
“Environmental Stewardship” goals.2 Among other uses, those funds may be spent
on projects to abate airport noise impacts (e.g., soundproofing of residential homes,
purchases of noise barriers and monitors, and relocation of persons or businesses);
to minimize water quality impacts (e.g., funding of projects that would control the
discharge of deicing chemicals); and to reduce airport-controllable air emissions
(e.g., purchases of alternative fuel vehicles). Funds also are authorized for research
into new aircraft technology that would reduce noise and air emissions.
Funding authorization for FAA programs set forth in Vision 100 — Century of
Aviation Reauthorization Act (P.L. 108-176, hereinafter referred to as “Vision 100”)
expired at the end of FY2007. On February 14, 2007, the FAA’s reauthorization
proposal, entitled the Next Generation Air Transportation System Financing Reform
Act of 2007 (H.R. 1356 and S. 1076, hereinafter referred to as “the FAA proposal”),
was introduced by request. Subsequently, reauthorization proposals have been passed
by the House (H.R. 2881, the FAA Reauthorization Act of 2007) and reported by the
Senate (S. 1300; S.Rept. 110-144, the Aviation Investment and Modernization Act
of 2007).3 Each bill includes environment-related provisions that would fund
projects intended to minimize environmental impacts or help airports comply with
regulatory obligations; fund research, such as new technology that would produce
quieter, more fuel-efficient aircraft; and amend existing environmental regulatory

capital development. For information about federal funding available to airports, see CRS

RL33920, Federal Aviation Administration Reauthorization: An Overview of Selected
Provisions in Proposed Legislation, coordinated by Bart Elias.

To illustrate why airports may need these funds and how they could potentially
utilize them, this report provides an overview of the main environmental impacts
associated with airport operations: noise, water quality, and air quality. Also
discussed are the environmental review requirements of the National Environmental
Policy Act of 1969 (NEPA, 42 U.S.C. §§ 4321-4347) and an overview of
environmental provisions in proposed legislation to reauthorize FAA programs.
This report does not discuss the national or international environmental impacts
of aviation in general. Therefore, a discussion of the aviation industry’s potential
contribution to global warming is not discussed. However, information about this
issue is included in the “For Additional Information” section below.
Overview of Airport Environmental Issues
In the next 15 years, air travel is projected to grow significantly.4 As a result,
airport development and expansion projects will likely become increasingly
important. A potential challenge to the completion of these projects is community
concern regarding airport environmental impacts. Airport operations involve a range
of activities that affect the environment, including
!the operation of aircraft;
!the operation of airport and passenger vehicles, and airport ground
service equipment (GSE);
!cleaning and maintenance of aircraft, GSE, and motor vehicles;
!deicing and anti-icing of aircraft and airfields;
!fueling and fuel storage of aircraft and vehicles;
!airport facility operations and maintenance; and
! construction.
The environmental impacts of these activities may intensify if an airport is
undergoing expansion. In some cases, before a state or local agency will allow an
airport to move forward with an expansion project, the airport authority must agree
to implement certain environmental mitigation projects. Community concern
regarding environmental impacts has caused projects to be delayed or cancelled.
All airports, regardless of size or location, are regulated to some degree under
local, state, tribal, or federal environmental requirements. Many of the
environmental regulatory requirements applicable to noise, water, and air quality
have been in effect for years — airport managers are accustomed to their compliance
requirements. However, the anticipated growth in air travel has heightened the
significance and complexity of some environmental regulatory issues. Also, several
new requirements are expected to result in potentially significant changes to airport
operations (in terms of procedural changes and potential investment in
infrastructure). The most significant issues include

Addressing Growth in Air Traffic, by Bart Elias.

!continuing community concern about noise,
!changes to Environmental Protection Agency (EPA) regulations
applicable to aircraft and airfield deicing operations,
!changes to EPA regulations applicable to oil spill prevention
planning, and
!state and local agency directives to monitor and control air pollution,
particularly toxic air pollutants.
Each of these issues is discussed below within the context of requirements applicable
to noise, water quality, and air quality issues. Primarily, the issues discussed in this
report involve activities that are unique to airport operations (e.g., deicing and aircraft
noise). Environmental compliance requirements commonly applicable to all
industrial operations (e.g., waste management, pesticide use, chemical use reporting)
are not discussed in this report.5
Noise Issues
Aviation noise may have a negative impact on the quality of life and property
values of members of a surrounding community. (Direct health impacts of noise are
more difficult to determine.) Although the percentage of people affected by aircraft
noise has been significantly reduced during the past 35 years by advancements in
aircraft technology and noise abatement efforts,6 aircraft noise is often the principal
focus for community groups and larger non-governmental organizations that oppose
runway expansion.
Despite improvements, noise continues to be a significant problem because
!the amount of air traffic is growing,
!the number of airliners and corporate jets is increasing, and
!airline traffic and noise is concentrated at a small number of airports
that are also likely to be among the largest airports.7
An airport may use various approaches to address airport noise issues. Selected
approaches, and challenges to implementing them, are summarized in Table 1. Each
approach is potentially eligible for federal funding.

sources, including For Greener Skies: Reducing Environmental Impacts of Aviation (National
Academy of Sciences [NAS], National Research Council, Committee on Aeronautics Research and
Technology for Environmental Compatibility, 2002).

Ultimately, decisions regarding mitigation measures and operational changes are
made by the airport authority in accordance with requirements of the state or local
government; land use restrictions can be suggested by the airport authority, but are
implemented entirely at the discretion of local government.8 The federal role is
primarily to fund those efforts, establish aircraft noise limits,9 and fund research.10
Interested stakeholders have debated for a long time how funding dollars should
be allocated. Airports are likely to prefer funding short-term operational and
mitigation strategies to address immediate needs. Others argue that an increased
proportion of federal funding should be directed toward research. For example,
according to the NAS, the National Aeronautical and Space Administration (NASA)
has set technically feasible noise reduction goals, but the level of funding for its
research programs is too low to achieve the current goals on schedule or to remove
noise as an impediment to the growth of aviation.11

Noise Through Policy and Technology” section of CRS Report RL33698,

Congress, coordinated by Bart Elias and CRS Report RS20531, Noise Abatement and
Control: The Federal Role, by David Bearden.
Water Quality Issues
Airport operations include many activities likely to result in the discharge of
pollutants to adjacent water bodies. Those activities include aircraft and airfield
deicing and anti-icing,12 fuel storage and refueling, aircraft and vehicle cleaning and
maintenance, and construction. These activities are regulated under provisions of
the Clean Water Act (CWA).

8 For examples of methods used by airports to address noise issues, see the FAA’s “Noise
Exposure and Land Use Information” Web page, provided pursuant to requirements
specified under Vision 100: [http://www.faa.gov/airports_airtraffic/airports/environmental/
airport_noise/noise_exposure_ma ps/].
9 The Airport Noise and Capacity Act of 1990 (ANCA; P.L. 101-508) required the phaseout
of certain older, louder aircraft. In 2005, the FAA established more stringent aircraft noise
standards applicable to all new airplane types designed on or after January 1, 2006 (it does
not require a phaseout of existing aircraft). See Federal Aviation Administration, “Stage 4
Aircraft Noise Standards; Final Rule,” Federal Register, 70(127), 38741-38750, July 5,


10 Research and development is primarily carried out by the National Aeronautical and
Space Administration (NASA). The FAA focuses on assessing noise compatibility, aircraft
certification, and regulatory issues, although some development of aircraft noise modeling
and assessment tools occurs within the FAA.

12 Deicing involves the removal of frost, snow, or ice from aircraft surfaces or from paved
areas, including runways, taxiways, and gate areas. Anti-icing refers to the prevention of
the accumulation of frost, snow, or ice on these same surfaces.

The CWA prohibits any “point source” (a discrete conveyance such as a
drainage ditch, pipe, or other outfall) from discharging pollutants into waters of the
United States. The primary mechanism for controlling pollutant discharges is
through the administration of the National Pollutant Discharge Elimination System
(NPDES) permit program, which is implemented, in most cases, by individual
states.13 The NPDES permit program regulates discharges of stormwater14 and
wastewater. Due to the nature of their outdoor operations and because airports are
included in one of the industrial categories regulated under the NPDES stormwater
permitting program (under the Standard Industrial Classification code
“Transportation by Air”), all airports are required to have a stormwater permit.15
Airports that discharge other wastewater, such as from equipment maintenance and
cleaning operations, require an additional NPDES wastewater permit.
Discharges associated with stormwater often pose the greatest challenge to
airport managers, because airports may be spread out over a wide surface area, with
a majority of operations exposed to the elements. For example, the Dallas Forth
Worth International Airport encompasses 18,000 square acres and has 62 stormwater
outfalls. Controlling or monitoring every outfall is difficult.
The primary method for controlling stormwater discharges is the
implementation of best management practices (BMPs) that prevent or minimize the
discharge of pollutants into a water body (e.g., construction of a stormwater retention
pond to prevent stormwater drainage directly into receiving waters). BMPs
appropriate for one airport are not necessarily appropriate for another. Factors that
may affect permit requirements (i.e., appropriate BMPs), include
!the local climate (dry versus rainy/wet, cold versus warm);
!the type or size of adjacent water bodies — pollutants are diluted
depending on the size of the water body receiving the discharge
(e.g., a creek or stream versus a river or ocean);
!the water quality of adjacent water bodies — local permitting
authorities consider existing pollutant levels when controlling airport
discharges; and
!airport size.
To comply with the Clean Water Act, most airport operators are particularly
concerned about managing deicing chemicals and preventing oil spills.

13 For more information about the NPDES Permit Program , see EPA’s Web page “NPDES
Permit Program Basics”: [http://cfpub.epa.gov/npdes/home.cfm?program_id=45].
14 Stormwater discharges are generated by runoff from land and impervious areas such as
paved streets, parking lots, and building rooftops during rainfall and snow events. By
running over contaminated surfaces, stormwater becomes polluted. Most stormwater
discharges are considered point sources and require coverage by an NPDES permit.
15 For more information, see EPA’s “Stormwater Program” Web page: [http://cfpub.epa.gov/
npdes/home.cfm?program_id=6], and CRS Report 97-290, Stormwater Permits: Status of
EPA’s Regulatory Program, by Claudia Copeland.

Deicing and Anti-icing Activities. With regard to water quality compliance
issues, the management of deicing and anti-icing chemicals poses the greatest
challenge to many airport operators. The deicing and anti-icing of aircraft and
airfield surfaces is required by the FAA to ensure the safety of passengers. However,
when performed without discharge controls in place, airport deicing operations can
result in environmental impacts.16
Discharges from deicing operations have the potential to cause fish kills, algae
blooms, and contamination to surface or ground waters. In addition to potential
aquatic life and human health impacts from the toxicity of deicing and anti-icing
chemicals, the biodegradation of propylene glycol or ethylene glycol (i.e., the base
chemical of deicing fluid) in surface waters (e.g., lakes, rivers) can greatly affect17
water quality, including significant reduction in dissolved oxygen levels.
Studies have also shown toxicological effects of deicer solutions that cannot be
attributed to either propylene glycol or ethylene glycol.18 This has led to concern that19
these effects are attributable to unknown, proprietary additives. The environmental
route and impact of these additives is not yet understood.
Typically, airlines are responsible for aircraft deicing and anti-icing operations,
and airports are responsible for the deicing and anti-icing of airfield pavement. The
airport is ultimately responsible for managing the resulting wastewater. This
responsibility is typically outlined in the airport’s stormwater permit.
As discussed above, significant differences exist among airport NPDES permits.
For example, a local permitting authority may impose specific requirements, such as
restrictions as to where deicing operations may occur, a requirement to use deicing
collection units to vacuum deicing fluid prior to entering the storm water system, or
requirements to use monitoring equipment to ensure compliance with the permit.
Other permits may simply allow the airport to discharge deicing fluids directly into
an adjacent water body.
According to the EPA, the disparity in airport permitting requirements has led
the agency to consider implementing national standards in the form of effluent

16 The EPA estimates that airports discharge approximately 21 million gallons of aircraft
deicing fluids each year. See EPA, Office of Water, “Preliminary Data Summary: Airport
Deicing Operations,” August 2000, available at [http://www.epa.gov/waterscience/guide/

limitation guidelines (ELGs) for airport deicing and anti-icing operations.20 ELGs
are national regulations for controlling wastewater discharges to surface waters.
ELGs are technology-based and specific to an industry. ELGs applicable to airport
deicing would be designed to provide uniform guidance for NPDES permit writers
across the country, thereby establishing a baseline standard for all airports.21
In 2004, the EPA began to develop ELGs for airport deicing operations. Initial
estimates from the EPA indicate that treatment technology and pollution prevention
practices could potentially reduce deicing discharges from the current level of 21
million gallons a year to 4 million gallons a year.22
As stated previously, many airports have strict permit provisions that specify the
management of deicing chemicals. Others have few controls. Those with few
controls may be required to make capital improvements to comply with new
permitting requirements. At this stage, cost estimates for the aviation industry as a
whole are not available.
The EPA is currently collecting survey data from airports and air carriers and
conducting detailed sampling programs. The current work will be used to identify
the best available technology that is economically achievable for treatment and
discharge of spent deicing liquids. The EPA currently plans to publish a proposed
rule in December 2007 and to take final action by September 2009.
Fuel Storage. Because airports need to store fuel onsite to refuel aircraft and
airport ground service equipment, most airports are required to develop a Spill
Prevention, Control, and Countermeasure (SPCC) plan.23 These requirements are
designed to ensure that facilities that store oil have planned for and taken measures
to prevent environmental damage resulting from oil spills. An SPCC plan is required
to include
!operating procedures intended to prevent oil spills, such as
procedures to inspect tanks and associated piping for leaks;
!control measures installed to prevent a spill from reaching navigable
waters, such as the construction of a dike, containment curb, or pit
around a tank or tank farm; and
!countermeasures to contain, clean up, and mitigate the effects of an
oil spill that reaches navigable waters, such as the presence of a spill
clean-up kit with sorbent booms or wipes.

20 See the EPA’s Web page “Airport Deicing Effluent Guidelines,” at [http://www.epa.gov/
21 Currently, there are no ELGs applicable to the air transportation industry.
22 EPA, “Preliminary Data Summary” (see footnote 15), p. 1-4.
23 SPCC planning requirements, at 40 C.F.R. 112 (referred to as the SPCC Rule), are
authorized under the Oil Pollution Act of 1990, an amendment to § 311 of the Clean Water

As listed above, one of the primary control measures required under the SPCC
requirements is the use of a secondary containment system for oil storage containers.
Such a system must be large enough to temporarily hold the entire contents of the
largest oil tank in the oil storage area, in the event of a breach in the system.24 For
example, if a tank farm had four 12,000-gallon tanks and two 5,000-gallon tanks, and
was the storage location for 10 mobile refueling trucks with 500-gallon tanks, the
tank farm would be required to have secondary containment sufficient to hold the
contents of the largest tank — 12,000 gallons.
When the EPA proposed new SPCC requirements in 2002, airport operators and
the EPA disagreed about the secondary containment requirements applicable to
mobile airport refueling trucks.25 In particular, airport operators argued that it was
impractical to require mobile refuelers to provide secondary containment equal to the
size of the tank because, during refueling operations, they would be expected to move
to various areas of the airfield that could not be fitted with secondary containment
To address these concerns, the EPA amended the SPCC Rule to exempt mobile
refuelers from specifically sized containment requirements.26 However, mobile
refuelers remained subject to the general secondary containment requirements of the
SPCC Rule (e.g., periodic testing of the container and piping).27
The EPA has extended the compliance date applicable to mobile refuelers (and
for other new SPCC requirements) to October 31, 2009. This pending regulation
may require airport operators to install necessary secondary containment mechanisms
to comply with the regulation, in addition to meeting other SPCC requirements
applicable to that facility.
Air Quality Issues
Airport emissions affecting local air quality come from both mobile and
stationary sources, including the following:
! Aircraft.
!Motor vehicles (e.g., cars and buses for airport operations, and
passenger, employee, and rental agency vehicles).

24 Required under 40 C.F.R. 112.8.
25 Airport mobile refuelers are vehicles that have a bulk storage container on board or towed
by the vehicle, designed or used solely to store and transport fuel for transfer into or from
an aircraft, ground service equipment, or other oil storage container.
26 Final Rule, 71 Federal Register 77266-77293, December 26, 2006. For additional
information on new and existing SPCC requirements, see the EPA’s “SPCC Rule” Web
page: [http://www.epa.gov/emergencies/content/spcc/index.htm].
27 Regulations regarding general secondary containment requirements are listed under 40
C.F.R. §112.7(c)-(d). Also see “SPCC Rule Amendments: Streamlined Requirements for
Mobile Refuelers,” December 2006, at [http://www.epa.gov/emergencies/content/spcc/
factsheet_mobile_refuelers_dec06.htm] .

!Ground service equipment (GSE) (e.g., aircraft tugs, baggage and
belt loaders, generators, lawn mowers, snow plows, loaders, tractors,
air-conditioning units, and cargo moving equipment).
!Stationary sources (e.g., boilers, space heaters, emergency
generators, incinerators, fire training facilities, aircraft engine testing
facilities, painting operations, and solvent degreasers).28
Airport operations may produce various regulated pollutants, including volatile
organic compounds (VOCs), carbon monoxide (CO), particulate matter (PM), lead,
sulphur oxides (SOx), and nitrogen oxides (NOx), known collectively as “criteria”
pollutants. They also may produce a complex array of toxic or hazardous air
pollutants (HAPs).29
Emissions of Criteria Pollutants. The Clean Air Act (CAA) directs the
EPA to regulate emissions of air pollutants. Under the CAA, the EPA is authorized
to establish emission standards,30 based on certain health and environmental criteria,31
for NOx (the primary pollutant associated with aircraft emissions), ozone, CO,
SOx, lead, and particulates. The National Ambient Air Quality Standards (NAAQS),
subsequently established by the EPA, specify allowable concentrations and exposure
limits for each of these criteria pollutants. A geographic area that meets the standard
is considered to be in “attainment” for a particular NAAQS; areas that do not meet
a standard are in “nonattainment.”32 A “maintenance” area is one that was previously
in nonattainment but is currently attaining the NAAQS subject to a maintenance
plan. 33
The CAA requires states to develop a State Implementation Plan (SIP) to34
demonstrate how they will implement, maintain, and enforce the NAAQS.
According to the Government Accountability Office (GAO), the aviation industry as

must undertake to monitor and control them, see “Air Quality Procedures for Civilian
Airports & Air Force Bases”: [http://www.faa.gov/regulations_policies/policy_guidance/

29 For information regarding air pollutant emissions from commercial aviation, see EPA’s
“Aircraft” Web page: [http://www.epa.gov/oms/aviation.htm].
30 See EPA’s “Regulatory Announcement: New Emission Standards for New Commercial
Aircraft Engines,” available at [http://www.epa.gov/oms/regs/nonroad/aviation/420f05015.
31 Ozone is not directly emitted from vehicles or aircraft but is formed by the reaction of
nitrogen oxides (NOx), volatile organic compounds (VOCs), and sunlight.
32 For information on areas currently designated as being in nonattainment, see the EPA’s
“Green Book Nonattainment Areas for Criteria Pollutants”: [http://www.epa.gov/oar/

a whole makes a limited contribution to all criteria pollutant emissions nationwide.35
However, individual airports (particularly large airports in urban areas) may
contribute significantly to local criteria pollutant levels. If an airport is located in a
nonattainment or maintenance area, it may be required to change its infrastructure or
operations to conform with provisions of the SIP, particularly if the airport is
undergoing an expansion that requires approval from a state or local agency.
Because aircraft emissions are a significant source of emissions at an airport,
and largely outside the control of the airport, emission reductions will likely have to
be made in operations or processes that the airport does control. For example, the
airport ground vehicles may be changed to alternative fuel vehicles, some GSE may
be converted to electrified systems, or older boilers and chillers may be replaced with
more energy-efficient systems.
Vision 100 included several provisions intended to reduce airport ground
emissions at commercial service airports located in air quality nonattainment and
maintenance areas.36 The FAA is implementing the Vision 100 airport emission
provisions in a single program called the Voluntary Airport Low Emission program
(VALE).37 The VALE program allows airport sponsors to use Airport Improvement
Program (AIP) and the Passenger Facility Charges (PFCs) to finance low-emission
vehicles, refueling and recharging stations, gate electrification, and other air quality
improvements. Participation in the VALE program is voluntary for airport sponsors
and state air quality agencies.
Emissions of Toxic Air Pollutants. Increasingly, airports and the FAA are
asked by various agencies and communities surrounding airports to analyze the
health impacts of aircraft and other airport-related sources of air toxics, also known
as hazardous air pollutants (HAPs). This information is needed primarily when
conducting an environmental review pursuant to National Environmental Policy Act
(NEPA; see discussion below) and at the request of local or state agencies.
Ten HAPs comprise the majority reported to occur in aircraft and/or GSE
exhaust: lead (also a criteria pollutant), formaldehyde, 1,3-butadiene, acetaldehyde,
xylene, benzene, toluene, naphthalene, acrolein, and propionaldehyde.38 Unlike

Environmental Reviews Under NEPA
If an airport project receives federal funding or requires some federal decision
(e.g., permit or approval), an environmental review of that project is required before
it can move forward. The term “environmental review” is used broadly, but usually
refers to the requirement that a federal agency review or consider the environmental
impacts of its actions pursuant to the National Environmental Policy Act of 1969
(NEPA; 42 U.S.C. § 4321 et seq).40 A review under NEPA results in one of the
!Preparation of an environmental assessment (EA) if the significance
of environmental impacts is uncertain, followed by the issuance of
a Finding of No Significant Impact (FONSI) if the impacts are not
found to be significant.
!Preparation of an Environmental Impact Statement (EIS) if it is
certain that a project’s environmental impacts are significant.
!A determination that a project is categorically excluded from the
requirement to prepare an EIS or an EA, if it has no significant
environmental impact.
As the proponent of the airport project or improvement, the airport authority is
responsible for identifying all environmental issues that must be addressed in the
NEPA documentation. Part of that effort includes analyzing all reasonable
alternatives that would meet a project’s purpose and need.
For projects requiring an EIS, the FAA documents the final project decision by
issuing a public Record of Decision (ROD). In addition to documenting the final
decision, the ROD documents any mitigation efforts that the airport operator is
required to implement as a condition for moving the project forward. The mitigation
actions may be stipulated be provisions of local, state, tribal or federal41

Research Needs and Analysis,” description of current research project, available at

40 For more information about NEPA, see CRS Report RL33152, The National
Environmental Policy Act: Background and Implementation, by Linda Luther.
41 NEPA Records of Decisions are available at [http://www.faa.gov/airports_airtraffic/
airports/environmental/records_decision/]. For an example of mitigation requirements, see
the ROD for Logan International Airport, p. 16, August 2, 2002.

Although the ROD may specify mitigation measures, mitigation is not required
under NEPA. NEPA specifies a process that the agency must complete to analyze
a project’s environmental impacts, but it does not dictate the outcome. That is,
NEPA does not require an airport to chose the project alternative with the least
environmental impacts. However, within the context of the NEPA process, the
environmental review may identify environmental compliance requirements that
would dictate a certain outcome (e.g., it may identify Clean Water Act requirements
that specify that the least environmentally harmful alternative be selected). Further,
the ROD may specify mitigation measures that an airport authority agreed to
implement as a condition of gaining local agency or community acceptance of a
project — not necessarily a measure required by local, state, tribal, or federal law.
To streamline the NEPA process, Vision 100 directed the FAA to develop an
“expedited, coordinated environmental review process” applicable to the aviation
project review process for airport capacity enhancement projects at congested
airports, aviation safety projects, and aviation security projects. The coordinated
process provides that any environmental review, analysis, opinion, permit, license,
or approval issued or made by a federal agency or airport sponsor for such a project
must be completed within a time period established by the Secretary of
Transportation, in cooperation with the agencies that participate in the process. The
coordinated process may be delineated in a memorandum of understanding between
the Secretary and the heads of other federal and state agencies who participate in the
process. Further, the act authorizes the FAA to define the scope and content of a
project’s EIS and requires all participating agencies to be bound by the purpose and
need and project alternatives analysis determined by the Secretary of Transportation.
On April 28, 2006, FAA issued Order 5050.4B, National Environmental Policy
Act (NEPA) Implementing Instructions for Airport Actions.42 The order delineates
the agency’s new NEPA policies and procedures, including the streamlining
requirements specified in Vision 100.
Environmental Provisions in
FAA Funding Proposals
To address issues associated with air quality, water quality, and community
noise impacts, and to assist airport operators with complying with local, state, and
federal requirements related to those impacts, the FAA proposal and the bills under
consideration in the Senate (S. 1300) and passed in the House (H.R. 2881) include
similar proposals that would
!provide funding for research into technology or processes that would
reduce noise, air emissions, water quality impacts, and energy use;
!provide grants for programs or projects intended to mitigate or
minimize regulated environmental impacts; and

42 Available at [http://www.faa.gov/airports_airtraffic/airports/resources/publications/orders/
envi ronmental_5050_4/].

!provide grants or specify regulatory procedures to assist airports in
complying with environmental requirements.
S. 1300 and H.R. 2881 also include provisions that would establish certain
requirements to reduce noise.
H.R. 2881 includes two unique provisions. The first (§ 509) would require FAA,
to the maximum extent possible, implement “sustainable practices” in the
construction and major renovation of air traffic control facilities in order to reduce
energy use and improve environmental performance at those facilities. Finally, each
proposal includes provisions seeking to modify the Air Tour Management Program,
a program designed to regulate commercial air tours over national park units
primarily in an effort to mitigate noise and other adverse impacts. These provisions
seek to narrow the scope of this program to park service units where noise or other
adverse impacts from air tours have been identified or could become a more
substantial issue. The second (§ 512) specifies the sense of the Congress with respect
to the European Union (EU) directive extending the EU’s emission trading proposal
to international civil aviation. The bill specifies that, by not working through the
International Civil Aviation Organization in a consensus-based fashion, the EU
directive is inconsistent with the Convention on International Civil Aviation, and that
it is antithetical to building international cooperation to address greenhouse gas
emissions from aircraft.
Research Funding
FAA Proposal. Section 601 would permanently authorize the Airport
Cooperative Research Program (ACRP).43 Under § 601, the FAA proposes to
increase funding from $10 million to $15 million for FY2008-FY2010 (specified
under § 102). Five million dollars per year of the ACRP funds would be set aside for
research activities related to the airport environment, including reductions in noise
and air emissions and addressing water quality issues.
The FAA proposal would also create a consortium to research aircraft
technologies that would produce lower energy, air emissions, and noise. The FAA
proposal (§ 606, “Research Consortium for Lower Energy , Emissions, and Noise
Technology Partnership”) would create the consortium by requiring FAA to work
with the existing Partnership for Air Transportation Noise and Emissions Reduction44
(PARTNER) to develop Continuous Low Energy, Emissions and Noise (CLEEN)
engine and airframe technology. The proposal would establish the following
performance objectives for the consortium:

43 The ACRP was authorized as a four-year pilot program under Vision 100 (49 U.S.C.
44511(f)). Funds for the program are authorized under the Airport and Airway Trust Fund
Authorizations, under the Airport Planning and Development and Noise Compatibility
Planning and Programs.
44 PARTNER is an aviation cooperative research organization sponsored by FAA, NASA,
and Transport Canada, operating out of the Massachusetts Institute of Technology.

!a 25% increase in aircraft fuel efficiency, compared to 1997
subsonic jet aircraft technology;
!a 50% reduction in nitrogen oxide emissions associated with aircraft
landings and takeoffs, relative to the International Civil Aviation
Organization standard adopted in 2004;
!a 10 decibel (dB) reduction, compared to 1997 subsonic jet aircraft
!a feasability determination regarding the use of alternative fuels in
aircraft systems; and
!a determination regarding the ability to retrofit or re-engine aircraft
to use new engine technologies.
Under the FAA proposal, funding would be authorized under the Next Generation
Air Transportation System program at “sums as necessary to carry out [the
program] .”
Senate Proposal. Provisions regarding the ACRP (§ 601) are essentially
identical to the FAA proposal, except that S. 1300 would also include $15 million in
funding for FY2011 (§ 601(b)). The bill also includes a proposal similar to FAA’s
that would create a research consortium (§ 602, “Reduction of Noise, Emissions, and
Energy Consumption from Civilian Aircraft”). Funding for the research consortium
would be made available from the Airport and Airway Trust Fund Authorizations for45
research and development. The bill directs the Administrator to designate an
institution as a “Consortium for Aviation Noise, Emissions, and Energy Technology
Research” to conduct research with NASA and other relevant industries. The
performance objectives the consortium is directed to accomplish are the same as
those in the FAA proposal.
Unique to S. 1300 is a provision regarding clean coal fuel technology. Section
603 would require the Department of Transportation to establish a research grant
program to develop synthetic jet fuel from clean coal. (However, the bill does not
provide a definition of “clean coal.”) Funds would be authorized from the Airport
and Airway Trust Fund. Section 603 would also require the FAA Administrator to
designate an institution as a “Center of Excellence for Coal-to-Jet Research.”
House Proposal. Under § 104 (“Research, Engineering, and Development”),
H.R. 2881 would amend the Airport and Airway Trust Fund Authorizations for
research and development for FY2008 through FY2011 by authorizing a total of
approximately $125 million for “environment and energy” projects and $20 million
for ACRP “environment” projects (as in the Senate and FAA proposals, H.R. 2881
would permanently authorize the ACRP (§ 907)).
H.R. 2881 includes a provision (§ 505, “CLEEN Research, Development, and
Implementation Partnership”) that is similar to the FAA proposal that would create
a consortium to develop Continuous Low Energy, Emissions, and Noise (CLEEN)
engine and airframe technology. H.R. 2881 does not specify that the FAA must work
with PARTNER to achieve the established performance goals. However, the goals

45 49 U.S.C. § 48102(a).

are the same as those specified in the FAA proposal and S. 1300. H.R. 2881
specifies that from FY2008 through FY2011, not more than $111 million may be
appropriated from the Airport and Airway Trust Fund Authorizations for this
H.R. 2881 also specifies certain environmental-related responsibilities of the
Next Generation Air Transportation System Joint Planning and Development Office.
Included is a directive to establish specific quantitative goals for, among other
factors, the environmental impacts of each phase of Next Generation Air
Transportation System. Those goals are required to take into account noise pollution
reduction concerns of affected communities to the greatest extent practicable in
establishing the environmental goals (§ 202).
Under Title IX, “Federal Aviation Research and Development,” H.R. 2881
includes the following additional environmentally related research and development
requirements (except where noted, the bill does not specifically authorize funds for
this research):
!Interagency research initiative on the impact of aviation on the
climate (§ 903) — directs the FAA Administrator, in coordination
with NASA and the U.S. Global Climate Change Science Program,
to establish a research initiative to assess the impact of aviation on
climate and to evaluate approaches to mitigate that impact.
!Research program on space weather and aviation (§ 910) —
would require the FAA Administrator, in coordination with the
National Science Foundation (NSF), NASA, and National Oceanic
and Atmospheric Administration (NOAA), to initiate a research
program on the impacts of space weather to aviation. To conduct this
research, the Administrator may use grants or cooperative
agreements. Further, the bill would authorize $1 million to be
appropriated for each of FY2008 through FY2011.
!Aviation gas research and development program (§ 911) —
would require the FAA to study technologies that would allow the
use of unleaded gasoline in piston-engine aircraft (currently, piston-
engine aircraft — mostly general aviation aircraft — use leaded
gasoline). The bill would authorize $750,000 to be appropriated for
each of FY2008 through FY2010.
!Research reviews and assessments (§ 912) — would require FAA
to contract with the National Research Council (NRC) to assess the
adequacy of FAA’s energy- and environment-related research
programs, and the impact of space weather on aviation.
!Research program on alternative jet fuel technology for civil
aircraft (§ 914) — this section is similar to the proposal in S. 1300
(§ 603) that would support coal research, except that the House
proposal would also require research into the development of
alternative fuels from additional sources, including natural gas,
biomass, ethanol, butanol, and hydrogen. Funds for the program
would be authorized from the Airport and Airway Trust Fund.

Mitigation Grants
FAA Proposal. Section 604 would provide grants for up to six environmental
mitigation demonstration pilot projects. Eligible projects would include those that
would reduce or mitigate aviation impacts on noise, air quality, or water quality in
the vicinity of the airport. The federal share of the projects would be 50% of the
project costs, up to $2.5 million, and would be apportioned under the AIP.
Senate Proposal. Section 215 of S. 1300 includes provisions that are
essentially identical to the FAA proposal providing grants for environmental
mitigation pilot programs.
House Proposal. Section 507 of H.R. 2881 includes provisions that are
essentially identical to the FAA proposal and those in S. 1300 providing grants for
environmental mitigation pilot programs.
Grants and Procedural Changes
to Assist with Environmental Compliance
The FAA proposal and provisions in S. 1300 include almost identical proposals
that would amend the state block program, address methods of implementing and/or
expediting requirements of the National Environmental Protection Act (NEPA), and
amend certain noise compatibility program requirements.
FAA Proposal. Section 602 would amend the state block grant program46 by
specifying that federal environmental requirements would apply to the program.
Both proposals also specify that any federal agency that must grant any approval (i.e.,
permit or license) to a state must consult with that state during the approval process.
Further, the federal agency would be required to use any state-prepared
environmental analysis associated with that approval.
Sections 603 and 605 address methods of implementing and/or expediting47
requirements of the National Environmental Protection Act (NEPA) and airport
noise compatibility planning requirements (Title 14 Code of Federal Regulations
(CFR), Part 150, commonly referred to as Part 150 requirements). Section 603
would amend current requirements that allow FAA to accept funds from an airport
sponsor to hire additional staff or obtain the services of consultants to expedite the
processing, review, and completion of environmental activities associated with an

46 49 U.S.C. § 47128.
47 Among other provisions, NEPA requires airport operators to consider the environmental
impact of any proposed action that may require federal funding or approvals. It also requires
them to look at all reasonable alternatives to meet a given project’s purpose and need, before
final decisions are made. For more information, see FAA’s “NEPA Implementing
Instructions for Airport Projects,” Order 5050.4B, April 2006, at [http://www.faa.gov/
airports_airtraffic/airports/resources/publications/orders/envi ronmental_5050_4/].

airport development project.48 The proposal would allow FAA to accept funds to hire
additional staff to: conduct “special environmental studies” related to a federally
funded airport project; conduct studies or reviews to support noise compatibility
measures approved under the Part 150 requirements; or implement environmental
mitigation efforts specified in a project’s final decision and delineated at the
completion of the NEPA process.
Section 605 would amend the existing noise compatibility program
requirements49 to allow grants to airport operators to assist them with meeting
environmental review requirements applicable to proposals to implement flight
procedures. Further, the proposal would allow a project sponsor to provide FAA
with funds to hire additional staff as necessary to expedite completion of the
environmental review necessary to implement flight procedures.
Senate Proposal. Section 210 of S. 1300 is essentially identical to § 602 of
FAA’s proposal regarding the state block grant program. Unique to S. 1300 is a
provision that would establish a pilot program for up to three states that do not
already participate in the block grant program.
Sections 211 and 212 of S. 1300 are essentially identical to §§ 603 and 605 of
FAA’s proposal regarding methods of implementing and/or expediting requirements
of NEPA.
House Proposal. Section 502 of H.R. 2881 is essentially identical to the
FAA proposal and S. 1300 (except for pilot program proposal in S. 1300) regarding
the state block grant program.
Sections 503 and 504 of H.R. 2881 are similar to the FAA proposal and S. 1300
provisions regarding methods of implementing and/or expediting NEPA
Unique to H.R. 2881 is a requirement to fund an “aircraft departure queue
management pilot program” (§ 508) at five public-use airports. The programs would
be required to develop and test new air traffic flow management technologies to
better manage the flow of aircraft on the ground and reduce ground holds and idling
times for aircraft to decrease emissions and increase fuel savings.
Also unique to H.R. 2881 is a directive to review the current regulatory
responsibilities of FAA and EPA with regard to establishing engine noise and
emission standards (§ 510). The review would be required to consider, among other
factors, the degree to which those standards could be evaluated and addressed in an
integrated manner.

Requirements to Address Noise Issues
In 1990, Congress mandated a phase out of non-Stage 3 aircraft over 75,000
pounds by December 31, 1999.50 This has allowed Stage 1 and Stage 2 aircraft under

75,000 pounds, primarily corporate and private-use aircraft, to continue to operate.

In 2006, such aircraft represented a relatively small number of all operational turbojet
aircraft under 75,000 pounds (approximately 1,330 or 13%). However, at some
airports, particularly smaller commercial and general aviation airports, their use
makes a disproportionate contribution to noise exposure contours. For example, the
Massachusetts Port Authority (Massport) reported that at the L.G. Hanscom Field in
Bedford, MA, non-Stage 3 aircraft accounted for less than 1% of the airport’s annual
traffic in 2005, yet were responsible for 23% of the noise energy produced by civil
aircraft.51 Also, some airport operators have reported that between 50% and 80% of
noise complaints lodged with the airport have been related to non-Stage 3 aircraft.52
As a result, several airports have sought to ban or restrict access to such aircraft.
Those efforts have generally been prohibited by FAA.
Senate Proposal. Section 711 of S. 1300 would address this issue by
prohibiting the operation of aircraft under 75,000 pounds, with certain exceptions,
unless it complies with Stage 3 noise levels. The prohibition would take effect five
years after the bill’s enactment.
Section 714 of the bill proposes the creation of an exploratory program for the
redevelopment of property purchased with noise mitigation funds or passenger
facility charge funds, to encourage airport-compatible land uses. The trial program
would involve up to four airport operators that have submitted a noise compatibility
program to FAA. Provisions in this section would also amend the list of allowable53
noise compatibility measures to include land use planning that will prevent the
introduction of additional incompatible land uses.
Section 214 of the bill would expand passenger facility fee eligibility for noise
compatibility projects at Los Angeles International Airport (LAX). The section
specifies that the funds may be used for a project for the Lennox School District,

50 Airport Noise and Capacity Act of 1990 (P.L. 101-508).

adjacent to LAX, pursuant to a settlement agreement reached between the airport and
the school district in February 2005.54
House Proposal. Like the Senate bill (§ 711), § 506 of H.R. 2881 would
prohibit the operation of aircraft under 75,000 pounds, unless it complies with Stage
3 noise levels. The prohibition would take effect, with generally the same exceptions
specified in S. 1300, after January 1, 2013.
Also, § 513 of H.R. 2881 specifies the sense of the House that the Port
Authority of New York and New Jersey should undertake an airport noise55
compatibility planning study — with particular attention given to the impact of
noise on affected neighborhoods, including homes, businesses, and places of worship
surrounding LaGuardia Airport and JFK Airport.
