Surface Transportation Reauthorization Legislation:
SAFETEA (S. 1072) and TEA-LU (H.R. 3550)
Summary
This report discusses significant legislative provisions regarding environmental
issues in House- and Senate-passed bills that would reauthorize federal highway,
highway safety, and transit programs for FY2004-FY2009. The Senate bill (S. 1072),
the Safe, Accountable, Flexible, and Efficient Transportation Equity Act of 2003
(SAFETEA), passed on February 12, 2004. The House passed its bill (H.R. 3550),
the Transportation Equity Act: A Legacy for Users (TEA-LU), on April 2, 2004. The
bills have now moved to conference.
During the reauthorization process, certain environmental issues have garnered
significant attention from both Members of Congress and interested stakeholders
(e.g., state transportation agencies, transportation construction organizations, and
environmental groups). This attention is due to both the impact that surface
transportation projects can have on the environment and the impact that compliance
with environmental requirements can have on project delivery.
Compliance issues related to the Clean Air Act (42 U.S.C. § 7401 et seq.) and
the National Environmental Policy Act (NEPA, 42 U.S.C. § 4321 et seq.), in
particular, have generated strong debate during the reauthorization process. For
many surface transportation projects, compliance with certain elements of each law
is required before federal funding can be obligated. A significant number of
environmental provisions in both the House and Senate bills either specify
procedures or authorize funding to facilitate compliance with one or both of these
laws.
In addition to provisions related to the Clean Air Act and NEPA, both the House
and Senate bills include provisions that would authorize funding for projects or
activities associated with environmental impacts from transportation-related projects.
Potential environmental impacts may require federal funding to mitigate or minimize
those impacts, to reduce pollution, or to ensure compliance with an applicable
environmental law or regulation. For example, provisions in the Senate bill would
set aside funds to mitigate stormwater discharge damage from highway projects.
Legislation authorizing surface transportation programs for FY1998-FY2003,
the Transportation Equity Act for the 21st Century (TEA-21, P.L. 105-178), expired
on September 30, 2003. In accordance with a series of extension bills, all existing
surface transportation programs continue to operate according to provisions of TEA-
21 while Congress considers reauthorization proposals. The most recent extension
(H.R. 5183) extended funding for surface transportation programs through May 31,
2005. This report will be updated.

Environmental Provisions in Surface
Transportation Reauthorization Legislation:
SAFETEA (S. 1072) and
TEA-LU (H.R. 3550)
Introduction
This report discusses significant legislative provisions regarding environmental
issues in House- and Senate-passed bills that reauthorize surface transportation
programs for FY2004-FY2009. These programs involve federal highway, highway
safety, and transit programs undertaken by the U.S. Department of Transportation’s
(DOT’s) Federal Highway Administration (FHWA) and Federal Transit
Administration (FTA). The Senate bill (S. 1072), the Safe, Accountable, Flexible,
and Efficient Transportation Equity Act of 2003 (SAFETEA), passed on February 12,
2004. The House passed its bill (H.R. 3550), the Transportation Equity Act: A
Legacy for Users (TEA-LU), on April 2, 2004. The bills are currently in conference.
During the reauthorization process, certain environmental issues have garnered
significant attention from both Members of Congress and interested stakeholders
(e.g., state transportation agencies, transportation construction organizations, and
environmental groups). This attention is due to both the impact that surface
transportation projects can have on the environment and the impact that compliance
with environmental requirements can have on project delivery.
Both the House and Senate bills include many provisions that relate to the
environment. Generally, the provisions do one of the following: authorize funding
to eliminate, control, mitigate, or minimize regulated environmental impacts
associated with a surface transportation program or project; or specify procedures
required to be undertaken to comply with certain environmental requirements. In
particular, both bills include provisions that would change the procedures DOT
would be required to follow to comply with the Clean Air Act and NEPA.
Authorization legislation for FY1998-FY2003, the Transportation Equity Act
for the 21st Century (TEA-21, P.L. 105-178), expired on September 30, 2003. In
accordance with a series of extension bills, all existing surface transportation
programs continue to operate according to provisions of TEA-21 while Congress
considers reauthorization proposals. The most recent extension, the Surface
Transportation Extension Act of 2004, Part V (H.R. 5183), extended funding for
surface transportation programs through May 31, 2005.
This report focuses primarily on provisions of H.R. 3550 and S. 1072
concerning environmental requirements that may affect federal funding or surface
transportation project delivery. Specifically, this report addresses proposed legislative
CRS-2
provisions related to compliance with the Clean Air Act and NEPA. Also included
is an overview of selected environmental provisions and issues that have gained
attention from environmental and transportation stakeholders. For a more detailed
background discussion of these and other key issues for reauthorization, see CRS
Report RL32057, Highway and Transit Program Reauthorization: An Analysis of
Environmental Protection Issues. For more information on the provisions of both the
House and Senate bills, see CRS Report RL32226, Highway and Transit Program
Reauthorization Legislation in the 2nd Session, 108th Congress.
Clean Air Act Issues and Provisions
One of the more obvious environmental impacts related to transportation is its
generation of air pollution, in particular “smog” and “soot.” Smog (ground-level
ozone) is not directly emitted from vehicles, but is formed by the reaction of nitrogen
oxides (NOx) and volatile organic compounds (VOCs), both of which are emitted
from vehicles in the presence of sunlight. Soot (particulate matter or PM) can be
generated from a variety of sources including the combustion of petroleum. If the
concentrations of soot and smog in the air, in addition to other pollutants, exceed
certain levels, they can have adverse effects on human health and the environment.
The Clean Air Act directs the Environmental Protection Agency (EPA) to
regulate emissions of air pollutants. Of relevance to transportation is EPA’s authority
to establish emission standards, based on certain health and environmental criteria,
for ozone, carbon monoxide (CO), NOx, and PM.1 The National Ambient Air
Quality Standards (NAAQS), subsequently established by EPA, specify allowable
concentrations and exposure limits for each “criteria pollutant.” A geographic area
that meets or exceeds the standard is considered to be in “attainment” for a particular
NAAQS; areas that do not meet a standard are in “nonattainment.”2 A “maintenance”
area is one that was previously in nonattainment, but is currently attaining the
NAAQS subject to a maintenance plan.3
The NAAQS for particulates, CO, NOx, and short-term (one-hour)
concentrations of ozone have been in effect since the 1970s. However, a more
stringent standard for ozone (an 8-hour concentration) and new standards for fine
1 Regulated particulates are either “coarse” (between 2.5 and 10 micrometers in diameter,
known as PM ) or “fine” (less than 2.5 micrometers, known as PM ). PM from
10
2.5
10
transportation sources may come from brake and tire wear, pavement wear, and other
vehicle degenerative processes. PM are emitted from combustion sources, such as diesel
2.5
engines. Fine particulates penetrate deeper into the lungs and remain lodged there, rather
than being exhaled, causing negative impacts on health. Also included on the list of criteria
pollutants are lead and sulfur dioxide. Transportation-related sources are not significant
sources of either of these pollutants.
2 For information on areas currently designated as in nonattainment, see EPA’s “Green
Book Nonattainment Areas for Criteria Pollutants,” available at [http://www.epa.gov/oar/
oaqps/greenbk/index.html].
3 For a more extended discussion of issues regarding NAAQS, see CRS Report RL30853,
Clean Air Act: A Summary of the Act and Its Major Requirements.
CRS-3
particulates (PM ) go into effect this year. In April 2004, part or all of 474 counties
2.5
were designated as in nonattainment for the new ozone standard. In June 2004, EPA
announced that part or all of 244 counties were in nonattainment for PM . This is
2.5
a preliminary determination. EPA intends to make its final determination by
December 31, 2004.4
The Clean Air Act requires states to develop a State Implementation Plan (SIP)
to demonstrate how they will implement, maintain, and enforce the NAAQS.5 The
SIP must include enforceable emission limitations and other control measures, as
well as schedules and timetables for compliance with NAAQS, if applicable.
Deadlines for compliance vary, depending on the severity of the pollution, but
generally a nonattainment area must demonstrate that it is making annual emission
reductions sufficient to reach attainment by the applicable deadline. If necessary, the
SIP must also include a “motor vehicle emissions budget.” This budget establishes
a goal the state must meet with regard to emissions from mobile sources such as cars,
trucks, and buses. States submit initial SIPs and subsequent revisions to EPA for
approval.
The attainment of NAAQS and the development of SIPs are relevant to surface
transportation issues for a variety of reasons. For example, transportation agencies
must consider SIP goals in developing long- and short-term transportation plans.
Also, whether or not federal funds will be made available for a surface transportation
project, or possibly the level of those funds, may depend upon the degree of
nonattainment in a given area.6
Conformity with Transportation Planning
State and metropolitan transportation planners are required under the Clean Air
Act to ensure that long-range transportation plans and short-range Transportation
Improvement Programs (TIPs) are in conformity with emission budgets established
in a SIP. Conformity is a way to ensure that federal funding and approval are given
only to transportation projects that are consistent with a state’s air quality goals.7
Specifically, Section 176(c) of the Clean Air Act requires that planned transportation
projects will not:
! Cause new air quality violations;
! Worsen existing NAAQS violations; or
! Delay attainment of relevant NAAQS.
4 For more information, see CRS Report RL32345, Implementation of EPA’s 8-Hour Ozone
Standard; and CRS Report RL32431, Particulate Matter (PM2.5): National Ambient Air
Quality Standards (NAAQS) Implementation.
5 42 U.S.C. § 7410.
6 Such areas are classified according to the extent to which pollution levels exceed the
standards; designations include marginal, moderate, serious, severe, and extreme.
7 For more information, see guidance from FHWA: Transportation Conformity: A Basic
Guide for State and Local Officials, June 19, 2000, available online at [http://www.
fhwa.dot.gov/environment/conformity/con_bas.htm].
CRS-4
Transportation plans look at a 20-year planning horizon and specify the long-
term goals for a metropolitan area’s transportation system. Before a new
transportation plan can be approved or a new project can receive federal funding, a
regional emissions analysis must demonstrate that the emissions projected in the plan
conform to the emissions budget established by the SIP. A new conformity
demonstration must be made for a transportation plan at least every three years.
A TIP identifies major highway and transit projects to be funded in the short
term (within the next three years) either in a metropolitan area (if that area is a
nonattainment or maintenance area) or on a statewide basis. Metropolitan TIPs must
be updated at least every two years, statewide TIPS at least every three years. TIPs
may also need to be updated when a new project is added. In practice, many large
urban areas obtain a new conformity determination for their TIPs on an annual basis.
Highway and transit projects cannot receive federal funds unless they are part of a
conforming TIP.8
While conformity has been required for more than a decade, its impact is
expected to grow in the next few years as a result of several factors, including the
new NAAQS for ozone and fine particulates; and the increase in emissions from
sport utility vehicles (SUVs) and other “light trucks.”9 These and other factors could
contribute to numerous metropolitan areas facing a temporary suspension of highway
and transit funds unless they impose sharp reductions in vehicle, industrial, or other
emissions. In a recent survey, the General Accounting Office (GAO) found that, over
the past six years, only five metropolitan areas have had to change transportation
plans in order to resolve a conformity lapse; but about one-third of local
transportation planners surveyed expected to have difficulty demonstrating
conformity in the future.10
The CMAQ Program
In the year following the Clean Air Act Amendments of 1990, the Intermodal
Surface Transportation Efficiency Act of 1991 (ISTEA)11 directed the Secretary of
DOT to establish and implement a Congestion Mitigation and Air Quality
Improvement (CMAQ) program. ISTEA authorized a total of $6.0 billion in funding
for surface transportation and other related projects that contribute to air quality
8 For a more extended discussion of the issues regarding conformity, see CRS Report
RL32106, Transportation Conformity Under the Clean Air Act: In Need of Reform?
9 SUVs, minivans, and pickup trucks, vehicles classified as “light trucks,” are regulated
less stringently than passenger cars. Their potential to impact air quality standards is tied
to the fact that sales of such vehicles represent a significant proportion of new vehicle sales
and that they potentially release greater levels of criteria pollutants than other passenger
cars. For more information, see CRS Report RS20298, Sport Utility Vehicles, Mini-Vans,
and Light Trucks: An Overview of Fuel Economy and Emissions Standards.

CRS-5
improvements and congestion mitigation. Under TEA-21, a total of $8.1 billion was
authorized for the program for FY1998-FY2003. DOT apportions CMAQ funds
according to weighting factors based on the severity of air pollution (i.e., the degree
on nonattainment for a given criteria pollutant) and the population in that area.
CMAQ funds are available to a wide range of government and nonprofit
organizations, as well as private entities contributing to public/private partnerships.
Decisions regarding which projects or programs to fund are generally made through
the appropriate metropolitan and/or statewide transportation planning organizations,
and involve the state or local air quality agency. Also, FHWA or FTA field offices
are required to coordinate the project selection process with EPA.
Projects and programs eligible for CMAQ funds must come from a conforming
transportation plan and TIP. According to guidance from DOT, such projects must
also be expected to result in “tangible reductions” in carbon monoxide, ozone
precursor emissions, or PM .12 CMAQ funds cannot be used for projects that will
10
result in new highway capacity. Specific types of projects eligible for CMAQ funds
include, but are not limited to:
! Transportation control measures;
! Inspection and maintenance programs for auto emission controls;
! Extreme low-temperature cold start programs;
! The purchase of publicly owned, alternative fuel vehicles;
! Traffic flow improvements;
! Transit and public transportation programs;
! Pedestrian and bicycle facilities and programs;
! Travel demand management strategies;
! Outreach and rideshare programs; and
! Fare/fee subsidy programs.13
According to FHWA, the most effective CMAQ-funded projects tend to be large
in scope and to directly affect vehicle emissions, such as inspection and maintenance
programs.
Legislative Provisions Regarding Air Issues
As provisions in the transportation reauthorization legislation are debated,
several air quality-related issues are being addressed by both Members of Congress
and interested stakeholders. This section discusses and compares general categories
of provisions in the House or Senate bill that relate, either directly or indirectly, to
attainment of the NAAQS.
12 DOT provides guidance to the FHWA and FTA regarding CMAQ program
implementation. For the most recent program eligibility criteria, see “Guidance on the
Congestion Mitigation and Air Quality Improvement (CMAQ) Program Under the
Transportation Equity Act of the 21st Century (TEA-21),” issued April 1999, available
online at [http://www.fhwa.dot.gov/environment/cmaq99gm.htm].

Changes to Conformity Demonstration Requirements. Both the
House and Senate bills would amend to Section 176 of the Clean Air Act regarding
how and when conformity demonstrations are made. Two issues of particular
concern to some Members of Congress are (1) the differences between the SIP, TIP,
and long-range transportation planning cycles; and (2) the absence of exemptions for
certain types of projects, including those that could improve air quality. A summary
of legislative provisions regarding conformity is provided in Table 1.

CMAQ Funding Authorization. Both the House and Senate bills would
retain the basic structure of the CMAQ program specified under TEA-21 and
increase its funding overall, compared to current levels ($8.1 billion for FY1998-
FY2003). The Senate bill would authorize a total of $13.4 billion over the
authorization period (FY2004-FY2009). The House bill would authorize a total of
$9.4 billion over the same period.
Provisions in both bills would expand eligibility for projects funded under the
CMAQ program. Each bill specifies funding eligibility in one of two ways. First,
new classes of projects may be proposed for addition to the CMAQ program by
amendment of 23 U.S.C. 149(b). Second, Congress may provide clarification for
projects for which funding may already be eligible, but for which there has been
some confusion among the regulated community regarding eligibility. Following is
a summary of projects in both groups:
CRS-8
! Transportation Systems Management and Operations — Both the
House and Senate bills would expand the scope of CMAQ funding
available for transportation systems management and operations.
The House bill includes a list of eligible activities, such as arterial,
freeway, work zone, and emergency management; electronic toll
collection; automated enforcement; traffic operations measures to
improve capacity; and traffic signal coordination. [S. 1072 §1701;
H.R. 3550 §1202]
! Advanced Truck Stop Electrification Systems — The House bill
would allow CMAQ funds to be used for systems that could help
reduce emissions from heavy-duty transport vehicles that are
frequently left idling overnight or for extended periods. Specifically,
funds could be made available for advanced truck stop electrification
systems that would provide electrical power for heating, air
conditioning, electronic, and communications equipment onboard
the vehicle. No similar provision is included in the Senate bill.
However, confusion regarding current eligibility for funding such
projects is discussed in the Senate’s SAFETEA Report of the
Committee on Environment and Public Works Report for S. 1072.
In the report, the Committee states that such systems qualify for
CMAQ funding under current law, and directs DOT and EPA to
issue guidance to all appropriate federal, state, and local agencies
regarding this issue. [S. 1072, S.Rept. 108-222, discussion of §1612;
H.R. 3550 §1828]
! Bicycle Transportation and Pedestrian Walkways — The Senate bill
would allow the use of Surface Transportation Program (STP) and
CMAQ funds for non-construction pedestrian and bicycle safety
projects. The bill reauthorizes $500,000 in annual funding for a
national, nonprofit pedestrian and bicycle safety clearinghouse. [S.
1072 §1607]
! Purchase of Alternative Fuels — The Senate bill would make
eligible for CMAQ funding projects or programs for the purchase of
alternative fuel or biodiesel. [S. 1072 §1612(a)]
! Emergency Communication Equipment — The Senate bill would
make eligible for CMAQ funding projects or programs involving the
purchase of “integrated, interoperable emergency communications
equipment.” [S. 1072 §1612(a)]
The Senate bill also would change the way the CMAQ program is implemented
through provisions that:
! Expand CMAQ eligibility to include areas in nonattainment for the
new PM and 8-hour ozone standards. [§1611]
2.5
! Clarify that CMAQ-type projects are eligible for CMAQ funds in
states with no nonattainment or maintenance areas. [§1612(b)]
! Require states to ensure that subrecipients of CMAQ funds have
emission reduction strategies for their fleets used in construction
projects located in nonattainment or maintenance areas when the
projects are funded with highway funds. [§1612(c)]
CRS-9
! Direct the Secretary of DOT to encourage states and MPOs to
consult with state and local air quality agencies in nonattainment and
maintenance areas on estimated emission reductions from proposed
CMAQ programs and projects. [§1613]
! Direct the Secretary of DOT, in consultation with EPA, to evaluate
and assess a representative sample of CMAQ projects to determine
their impacts on air quality and congestion levels and to ensure the
effective implementation of the program. No direct funding is
provided for the evaluation. [§1614]
Unique to the House bill is a provision that would establish a motor vehicle
congestion relief program (§1201) to be funded under existing federal highway
programs, including CMAQ.14 The program would fund state projects that focus on
relieving motor vehicle traffic congestion in urbanized areas with populations greater
than 200,000. Congestion relief activities for which funding could be authorized
include:
! The construction of additional lanes, improved interchanges, or
improved access to major terminals, or the construction of parallel
roads or truck-only lanes;
! Improvements to systemwide reliability through activities such as
incident management programs, traffic monitoring and surveillance,
and traveler information initiatives; and
! Activities that could maximize the use of existing lanes through such
means as reversible lanes, coordination of traffic signals, or lane
management strategies.
Use of HOV Lanes for Hybrid Vehicles. Because of their energy and
environmental benefits, some states have extended to drivers of hybrid vehicles an
exception from high occupancy vehicle (HOV) lane requirements. Under TEA-21,
states were given the authority to grant HOV exemptions to “Inherently Low
Emission Vehicles” (ILEVs). The ILEV standard requires that a vehicle have no
evaporative emissions, a standard that is not met by any current hybrid. However,
because of the reduced emissions and improved fuel economy of hybrid vehicles,
there is congressional interest in explicitly granting states the right to exempt them
from HOV lane requirements.15
Both the House and Senate bills would continue and expand upon HOV lane
exceptions established under TEA-21. Both bills include provisions that would:
! Allow exceptions for motorcycles and “low emission and highly fuel
efficient” vehicles (the definition of which may include hybrid
vehicles);
14 The program would also be funded from set-asides under the Surface Transportation
Program, National Highway System, and Interstate Maintenance programs.
15 For more information, see the discussion on “Hybrid Vehicles” in CRS Issue Brief
IB10128, Alternative Fuels and Advanced Technology Vehicles: Issues in Congress.
CRS-10
! Require DOT or EPA to establish a process for identifying vehicles
that meet the exception criteria;
! Provide for the discontinuation of these exceptions if the operation
of HOV lanes becomes seriously degraded as a result of lane
exceptions.
Clean Fuels Formula Grant Program. TEA-21 established a clean fuels
formula grant program to assist transit operators in the purchase of low-emission
buses and related equipment, construction of alternative-fuel fueling facilities,
modification of garage facilities to accommodate clean-fuel vehicles, and utilization
of biodiesel fuel.16 Projects in the grants program were to be funded under the Mass
Transit Account of the Highway Trust Fund and with general U.S. Treasury revenues.
Total funding set aside under TEA-21 for this grant program was $1 billion. Funds
were to be apportioned to recipients in urbanized areas designated as nonattainment
or maintenance areas for ozone or carbon monoxide. However, during the
appropriations process, Congress subsequently redirected these funds to a more
general fund for bus purchases not restricted to fuel type. While this grant program
has not been implemented, transit agencies have purchased clean fuel buses at their
discretion.17
Section 3009 of the House bill would amend the grant program to change the
definition of a “clean fuel bus” and how funds may be apportioned. The program
would provide grants to urban areas on a formula basis to purchase clean fuel buses.
The formula is based on the size of the bus fleet weighed against the severity of
nonattainment within the metropolitan region. The House bill would set aside a total
of $525 million under the grants program. The Senate bill does not reauthorize the
grant program. However, there are no provisions in the Senate bill that would restrict
a transit agency from continuing its current practice of using funds from other transit
programs to purchase such buses.
Environmental Review Issues and Provisions
Before final design, property acquisition, or construction on a highway or transit
project can proceed, the FHWA and FTA must comply with all applicable
environmental review requirements, including those of the National Environmental
Policy Act of 1969 (NEPA).18 NEPA requires all federal agencies to consider the
16 42 U.S.C § 5308.
17 For FY2000-FY2002, approximately $1.4 billion was obligated by FTA to assist transit
agencies in the purchase of alternative fuel buses. This amount represented approximately
34% of the federal funding obligated for the purchase of new transit buses for that period.

18 An “environmental review” refers to a requirement to show evidence of formal
consideration, evaluation, or analysis of the impacts of a proposed federal action. Most
often, the use of the term is in reference to the process of complying with NEPA
requirements. However, depending upon the project at issue, an environmental review may

environmental impacts of proposed federal actions. To ensure that environmental
impacts are considered before final decisions are made, NEPA requires the
preparation of an environmental impact statement (EIS) for any federally funded
action that significantly affects the quality of the human environment. Projects for
which it is not initially clear whether impacts will be significant require the
preparation of an environmental assessment (EA). If it is determined at any time
during the assessment that a project’s impacts will be significant, an EIS must be
prepared. Projects that do not individually or cumulatively have a significant social,
economic, or environmental effect, and which DOT has determined from past
experience have no significant impact, are processed as categorical exclusions.
In addition to meeting NEPA requirements, any given transportation project may
require compliance with a wide variety of legal requirements, enforceable by multiple
agencies. For example, impacts of a highway project may trigger compliance with
elements of the Clean Air Act, the Endangered Species Act of 1973 (16 U.S.C.
1536), the National Historic Preservation Act (16 U.S.C. 470), or the Clean Water
Act (33 U.S.C. 1251). FHWA regulations require that compliance with all applicable
environmental laws, executive orders, and other legal requirements be documented
within the appropriate NEPA documentation (a concept referred to as the “NEPA
umbrella”).19
Legislative Provisions Regarding Environmental Reviews
Some Members of Congress have expressed concerns that the environmental
review process, particularly for large, complex surface transportation projects, can
be inefficient, leading to delays in completion of those projects. To address this
concern, TEA-21 included “Environmental Streamlining” provisions. Some
Members of Congress have expressed the need for further legislation to expedite the
environmental review process required of highway and transit projects. In response
to that need, both the Senate and House bills would repeal TEA-21’s streamlining
provisions and institute new procedures intended to expedite the environmental
review process.
Streamlining Environmental Reviews. Section 1511 of the Senate bill
would establish a new “transportation project development process” that could be
implemented at the request of the project sponsor.20 The new process and related
provisions in S. 1072, applicable to highway and transit projects, include the
following:

requirement.

Projects: Analysis of SAFETEA and Recent Legislative Activities.
20 Otherwise, current regulatory requirements that specify “Environmental Impact and
Related Procedures” under 23 C.F.R. 771 will apply.
CRS-12
! A codification of DOT’s traditional role as the lead federal agency
responsible for completion of the environmental review process.
! A statutory delineation of the roles and responsibilities of the lead
agency and cooperating agencies.
! A requirement to establish a “coordination plan” to coordinate
agency and public participation and to develop a schedule for
completion of the environmental review process.
! Provisions for the collaborative development of the project’s
statement of purpose and need and project alternatives as required
under NEPA or any other applicable statute.
! A requirement to follow specified dispute resolution procedures in
the event a cooperating agency identifies “major issues of concern”
regarding the potential environmental or socioeconomic impacts of
a project.
Section 1512 of the Senate bill would authorize states to assume responsibility
for determining whether certain designated activities may be included within the
class of actions currently identified in FHWA regulations as categorical exclusions.
The criteria for making such a determination would be established by the Secretary
of DOT and would apply only to projects designated by the Secretary. Such authority
would be determined through a mutual agreement between the state and the Secretary
and delineated in a memorandum of understanding.
Section 1513 of the Senate bill proposes the establishment of a “surface
transportation project delivery pilot program” that would delegate certain additional
federal environmental review responsibilities to no more than five states, including
Oklahoma. Responsibility could be assumed for environmental reviews required
under NEPA, or any federal law, for one or more highway projects within the state.
The program would be administered in accordance with a written agreement between
the participating state and the Secretary. The Secretary is directed to promulgate
regulations to implement the pilot program within 270 days of enacting the law.
Unless otherwise specified, Section 1515 of the Senate bill directs the Secretary
to promulgate regulations to implement each of the provisions discussed above
within one year of enacting the law.
The House bill includes provisions related to the environmental review process
under Section 6002, “Efficient Environmental Reviews for Project Decisionmaking.”
Like the Senate bill, TEA-LU specifies certain provisions intended to reduce delays
arising from the environmental review process. The House bill’s “project
development procedures” would be applicable to all highway projects, public
transportation capital projects, and multimodal projects that require an EIS and may
be applied to other projects if appropriate. Further, provisions regarding the project
development procedures would:
! Statutorily designate DOT as the lead federal agency and the project
sponsor (if a state or local government) as the joint lead agency for
the environmental review process.
CRS-13
! Allow the joint lead agency to prepare any supporting documents if
the federal lead agency provides guidance and assistance and
approves the documents.
! Require the environmental review process to be initiated by the
project sponsor.
! Require the project’s statement of purpose and need to be defined
and the project alternatives to be determined by the lead agency after
participating agencies and the public have an opportunity for
involvement.
! Establish an extendable 60-day deadline on comments to a draft EIS
and an extendable 30-day deadline on all other comment periods in
the environmental review process.
! Establish a dispute resolution process intended to identify and
resolve issues of concern that could delay completion of the
environmental review process.
! Require a state participating in the environmental review process to
require the participation of all appropriate state agencies.
! Allow project funds to be provided to state and federal agencies to
support activities related to the environmental review process that
would expedite project delivery.
! Establish a 90-day statute of limitation on claims concerning final
agency actions.
TEA-LU does not specifically direct the Secretary to develop or promulgate
regulations to implement the environmental review provisions of the bill.
Revisions to “Section 4(f)” Requirements. Included in the Senate bill
are revisions to “Section 4(f)” provisions of the Department of Transportation Act
of 1966.21 Section 4(f) requirements apply to publicly owned parks and recreation
areas, and wildlife and waterfowl refuges. They also apply to public or privately
owned historic sites of national, state, or local significance. Under current law, any
use of such a resource for a transportation project is prohibited unless there is no
prudent and feasible alternative to do otherwise, and the project includes all possible
planning to minimize harm to the resource.
Both the House (§6003) and Senate (§1514) bills would amend current statutory
provisions related to Section 4(f). The Senate bill would amend the current law to
allow for the use of a Section 4(f) resource if it is determined that such use would
result in “de minimus impacts” to that resource. The House bill includes a similar
provision; however, it would apply only to the use of historic sites. TEA-LU would
allow the use of a historic site if the use is determined, in accordance with provisions
of the National Historic Preservation Act (16 U.S.C. 470f), to have no “adverse
21 Section 4(f) of the DOT Act was originally set forth at 49 U.S.C. § 1653(f) and applies
to all DOT projects. A similar provision, found at 23 U.S.C. § 138, applies specifically to
federal-aid highways. In 1983, as part of a general recodification of the DOT Act, 49 U.S.C.
§ 1653(f) was formally repealed and codified in 49 U.S.C. § 303 with slightly different
language. This provision no longer falls under a “Section 4(f),” but DOT has continued this
reference, given that over the years, the whole body of provisions, policies, and case law has
been collectively referenced as Section 4(f).

effect” on the site. Also, provisions in both the House (§6004) and Senate (§1604)
bills would specifically exempt the Interstate System, segments of which are
approaching 50 years old, from consideration as a historic site pursuant to Section
4(f).
Additional Environmental Issues
Provisions involving the implementation of the Clean Air Act and NEPA have
garnered the most attention and debate during the transportation reauthorization
process. However, some Members of Congress have also expressed concern
regarding a variety of other environment-related issues. In particular, both the House
and Senate bills authorize funding for projects or activities that minimize or mitigate
potential environmental impacts of transportation-related activities. Each bill also
authorizes funding for research that may ultimately prove beneficial to the
environment.
Expansion of Environmental Projects Eligible for Funding
A variety of highway programs, including the Surface Transportation Program
(STP) and the National Highway System (NHS) program, are funded through the
highway trust fund. The STP provides funding that may be used by states and
localities for projects on any federal-aid highway. The NHS program provides
funding to states for improvements to rural and urban roads that are part of the
national highway system, including the Interstate System and designated connections
to major intermodal terminals.
Both the House and Senate bills set aside STP and/or NHS funds for specific
projects. However, the Senate bill would authorize the use of STP and/or NHS funds
for a variety of programs or projects intended to minimize or mitigate environmental
impacts related to surface transportation projects. Following is a list of such projects
or programs for which STP and/or NHS program funds are either required to be spent
or for which such funds may be eligible under S. 1072:
! Habitat and Wetlands Project Mitigation Fund — The Senate bill
would allow a state to deposit into a habitat and wetlands mitigation
fund part of the funds apportioned to it under the STP and NHS
programs. [§1505]
! Environmental Restoration and Pollution Abatement — The Senate
bill would expand eligibility under both the STP and NHS programs
to fund pollution abatement and environmental restoration projects.
To minimize or mitigate the impacts of any transportation project,
S. 1072 would allow environmental restoration and pollution
abatement to be carried out to address water pollution or
environmental degradation caused wholly or partially by a
transportation facility. This would include retrofitting and
construction of storm water treatment systems to meet federal and
state requirements under the Federal Water Pollution Control Act
(33 U.S.C. 1341, 1342). [§1601]
CRS-15
! Control of Invasive Species — The Senate bill would expand
eligibility under both the STP and NHS programs for the control of
invasive species and the establishment of native plant species.
Activities funded under the program would include participation in
statewide inventories of invasive plant species and desirable plant
species; regional native plant habitat conservation and mitigation;
native re-vegetation; and elimination of invasive species to create
fuel breaks for the prevention and control of wildfires. [§1601]
! Highway Stormwater Discharge Mitigation Program — Stormwater
mitigation is currently eligible for STP funding as a Transportation
Enhancement project. The Senate bill would require 2% of a state’s
STP apportionment to be available for mitigation projects to
improve the quality of stormwater discharge from federal-aid
highways. Funding could be provided for projects that reduce
flooding; recharge groundwater; promote natural filters; minimize
stream bank erosion; and improve water quality. The Secretary of
DOT would be required to issue guidance to assist states in carrying
out the program. [§1620]
Funding for Surface Transportation Research Projects
Both the House and Senate bills authorize funding for transportation research
projects out of the highway trust fund. Both bills authorize funding for surface
transportation research related to the environment.
Advanced Vehicle Technologies Research. Authorized under TEA-21,
the Advanced Vehicle Technologies Program (AVP) was intended to research means
of improving energy efficiency while reducing emissions and transportation
dependence on petroleum. Of $250 million authorized for this program under TEA-
21, Congress appropriated a total of $10 million.
The Senate bill would repeal TEA-21’s AVP program and would not replace it.
The House bill (§ 5401) would replace the program with an “Advanced Heavy-Duty
Vehicle Technologies Research Program.” Provisions in the House bill direct the
Secretary of DOT to conduct research, development, demonstration, and testing on
advanced heavy-duty vehicle technologies. The total authorization for the program
would be $34 million. At least 50 percent of program funding would be required to
be provided by non-federal sources.
Surface Transportation Environment and Planning Cooperative
Research Program. Established under TEA-21, the Secretary of DOT was
required to establish a surface transportation-environment cooperative research
program. Included among the program’s research priorities is a requirement to
improve understanding of the factors that contribute to the demand for transportation;
develop indicators of economic, social, and environmental performance of
transportation systems to facilitate analysis of potential alternatives; and study the
relationship between highway density and ecosystem integrity. One component of
the program was the establishment of an Advisory Board to make recommendations
on environmental and energy conservation research, technology, and technology
transfer activities related to surface transportation. Under the program, the Secretary
CRS-16
was authorized to make grants to, and enter into cooperative agreements with, the
National Academy of Sciences to conduct activities relating to transportation-
environmental research. Over TEA-21’s authorization period (FY1998-FY2003),
Congress did not appropriate funds for this program.
Both the House (§5203) and Senate (§2101) bill include provisions that would
reauthorize funding for the program. The House bill would set aside $5 million for
FY2004 and $15 million per year for FY2005-FY2009 from the Surface
Transportation Research funds. The House bill would also allow additional funding
to be sought from public and private sources. The Senate bill would set aside $20
million a year, for the six-year reauthorization period, from Surface Transportation
Research funds. The Senate bill would allow research to address planning and
evaluation models, factors contributing to transportation demand, and transportation
performance indicators to meet environmental requirements and facilitate analysis
of potential alternatives.
