Federal Requirements Concerning Hazardous and Nonhazardous Waste

Projects that include purchase of new right-of-way, excavation, or demolition or modifica­tion of existing structures should be evaluated to determine whether there is any known or potential hazardous waste within the proposed project limits. Where hazardous substances are involved, adequate protection must be provided to employees, workers, and the com­munity prior to, during, and after construction. Typical materials that may constitute haz­ardous waste include pesticides, organic compounds, heavy metals, industrial waste, or other compounds injurious to human health and the environment.

Assessment of the potential presence of hazardous materials is conducted in two stages referred to as phases I and II. Phase I investigations are based on documentary research and visual observation to identify concerns and evaluate the likelihood that hazardous sub­stances have affected the property. Phase II includes the on-site collection of soil or water samples and completion of laboratory analysis to confirm that contamination is present. Phase I generally consists of historical research to evaluate current and past land uses and operations with a focus on what hazardous substances may have been introduced into the soil or water (including groundwater at the site); a search of regulatory records to evaluate whether the site or adjacent properties are listed in files as having violations, recorded haz­ardous substances releases or incidents, or a history of storing, handling, using, transport­ing, or disposing of hazardous substances; physical description of the soil geology and of surface water and groundwater, in order to evaluate the potential for migration of contam­inants from the source to another property; and a site walk to observe the site conditions and operations as well as those of the neighboring properties. Phase II is a specifically designed sampling and analysis program that effectively addresses the concerns raised in the Phase I study. Phase II should be designed to collect sufficient data to establish that a valid concern exists and to indicate what level of remediation may be required to address the concern. The American Society for Testing and Materials (ASTM) has developed a standard for completion of Phase I and Phase II investigations.

Resource Conservation and Recovery Act (RCRA). The Resource Conservation and Recovery Act was enacted in 1974, and amended in 1984, to address growing concerns related to disposal of hazardous and nonhazardous waste. RCRA requires states to develop EPA-approved hazardous waste management plans and encourages options other than landfill disposal for final disposition of hazardous waste. A major objective of RCRA is to conserve and protect environmental resources, including the land resource that is lost to other uses when it is filled with solid waste. RCRA established

• A system for defining hazardous waste

• A method to determine whether hazardous waste has been generated

• Guidelines on how to store, handle, or treat hazardous waste

• Standards for proper disposal of waste

• Methods to track hazardous waste to its ultimate disposition

Resource recovery is an important area mandated by RCRA, and covers several mate­rials used in highway construction, such as recycled glass, scrap tires, and recycled con­struction materials. Some hazardous materials can also be treated and recycled for use in highway construction. RCRA also covers issues of “use constituting disposal” for projects that seek to use embankments or road subbase as disposal areas for hazardous waste, if suit­ability can be demonstrated. Some of the research and demonstration projects in the area of resource recovery that are applicable to highways are discussed later in this chapter.

Toxic Substances Control Act (TSCA). The Toxic Substances Control Act sets the policy for testing suspected toxic substances to evaluate persistence in the environment and their effect on humans (acute toxicity levels and/or carcinogenic effects). TSCA also reg­ulates toxic substances not regulated by RCRA such as asbestos-containing materials (ACM) and polychlorinated biphenyls (PCBs), both of which may be found in existing highway facilities.

Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA).

The Comprehensive Environmental Response, Compensation, and Liability Act was passed in 1980. It established national policy and procedures for identifying and remediat­ing sites that are found to be contaminated with hazardous substances, and identified pro­cedures for containing and removing releases of hazardous substances. CERCLA was amended and expanded by the Superfund Amendments and Reauthorization Act of 1986 (SARA). CERCLA established a hazard ranking system sites. The highest ranked sites have been placed on the National Priorities List (NPL) and are eligible for funding for envi­ronmental cleanup under CERCLA.

CERCLA provides for “joint and several liability,” which means that any party identi­fied as responsible for contamination of a site is considered equally responsible for cleanup costs with all other parties identified, and can be held 100 percent financially responsible in the event that other parties do not pay. Recovering costs from nonpaying parties is then the burden of the paying party and is pursued through the judicial system. Potentially responsible parties (PRPs) may be current or past owners and/or operators of a site where hazardous substances have been released, or persons who arranged for disposal or treat­ment of hazardous substances at the site. In addition, any person who knowingly accepted hazardous substances for transport to the site may be considered a PRP. Liability under CERCLA may also be retroactive to an era when the practices leading to the contamination were accepted industry standards. Petroleum is excluded from CERCLA unless mixed with other hazardous substances, in which case the entire mixture is considered hazardous. Provisions have been established under SARA for an Underground Storage Tank Trust Fund that will address petroleum releases.

A key concept mandated by CERCLA is “cradle-to-grave” responsibility for hazardous substances. Liability for a hazardous substance begins when it is accepted on the site or for­mulated at the site and continues after it is disposed off-site at a legally permitted facility.

CERCLA is important to the highway planning process primarily in the acquisition of right-of-way. Accepting financial liability for contaminated property may affect the finan­cial feasibility of a project. In addition, if significant cleanup must take place before high­way construction can begin, substantial delays to the project may result. The presence of contaminated materials along the alignment of a proposed highway alignment may be a crucial element in determining whether it is viable route. Careful evaluation of the nature and extent of the contamination as well as the cleanup alternatives, costs, schedule, and ongoing liability is warranted on all sites within a planned right-of-way purchase. Title III of SARA established mandatory federal standards for community right-to-know programs, and for reporting toxic chemical release by manufacturers.

Federal Requirement Protecting Water Resources and Sensitive Ecological Resources

Clean Water Act (33 USC §1251 et seq. CWA). The CWA was enacted in 1977 as amend­ments to the Federal Water Pollution Control Act of 1972. Its stated goal is to “restore and maintain the chemical, physical, and biological integrity of the Nation’s waters.” The CWA gave EPA the authority to implement pollution control programs such as setting wastewater standards for industry. The CWA also contained requirements to set water quality standards

for all contaminants in surface waters, and provided funding for the construction of sewage treatment plants under the construction grants program. It also recognized the need for planning to address the critical problems posed by nonpoint source pollution.

One of the mechanisms to achieve the objectives of the CWA is the prohibition of dis­charges, including dredge and fill material, into navigable waters. The CWA made it unlawful for any person to discharge any pollutant from a point source into navigable waters, unless a permit was obtained under its provisions. Sections 402 and 404 of the CWA establish two complementary permit programs through which appropriate federal or state officials may authorize the discharge of pollutants.

Section 402 of the CWA has led to development of the National Pollutant Discharge Elimination System (NPDES) under which permits are issued for the discharge of material that is other than dredge or fill, including storm water runoff from highway facilities into navigable waters.

Under subsections 402(p)(2)(C) and (D) of the CWA, storm water permits are neces­sary for discharges from a municipal separate storm sewer system serving an incorporated or unincorporated area with a population over 100,000. The EPA definition of municipal separate storm sewer is “a conveyance or system of conveyances (including roads with drainage systems, municipal streets, catch basins, curbs, gutters, ditches, manmade chan­nels, or storm drains).” The definition goes on to specify that the system of conveyances may be owned by any of a number of types of municipal governing bodies and specifically includes states, that the conveyances must be specifically designed for the purpose of collecting or conveying storm water, and that they are not to be part of a combined sewer or part of a publicly owned treatment works (POTW).

Section 404 of the CWA has led to the development of a permit program adminis­tered by the USACOE for the deposition of dredged or fill materials into navigable waters. The definition of navigable waters has been contested in several recent Supreme Court decisions that have begun to limit the reach of the CWA permit authority in wet­lands to areas that have a significant nexus with navigable waters. In June 2007, the EPA and USACOE issued agency guidance regarding CWA jurisdiction following two of these recent decisions the consolidated cases Rapanos v. United States and Carabell v. United States [126 S. Ct. 2208 (2006)].

States often have overlapping jurisdiction with the USACOE regarding permitting of actions within navigable waters. State permits related to navigation and wetland encroach­ment are common and need to be taken into account when developing a project. State pro­grams are usually more restrictive, with a more expanded definition of wetland boundaries or a regulated buffer zone. In two states—Michigan and New Jersey—some permitting authority has been ceded to the state, simplifying the process.

The CWA prohibits storm waters from being used to transport or collect wastes and requires that standards for water pollution be established that do not diminish the uses of the water. EPA has the authority to develop a framework of regulation that can be fully del­egated to states once the EPA has approved their regulatory program. The CWA requires states to establish a policy of nondegradation that protects and preserves water (J. T. Dufour, California Environmental Compliance Handbook, California Chamber of Commerce, Sacramento, 1993, pp. 72-74).

In the preamble of the November 1990 amendments to the CWA, EPA explains its deci­sion to include state-owned highways as municipal separate storm sewers. EPA identifies dis­charges from state highways as a significant source of runoff and pollutants and as one of the “issues and concerns of greatest importance to the public” (Federal Register, Part II, Environmental Protection Agency 40 CFR 122, 123, and 124, November 16, 1990, p. 48039).

To avoid the problems associated with multiple permittees for systemwide discharges, the CWA regulations include a method whereby interconnected systems owned and oper­ated by local agencies and state-owned highways in areas of medium to high population may be combined into a single permit. The regulations allow the state transportation agency to be named as a copermittee in a systemwide permit, or to be named in a separate municipal permit. (E. M. Jennings, “Coverage of State Highways under Municipal Storm Water Permits,” Memorandum, Office of Chief Counsel, California State Water Resources Control Board, Sacramento, November 2, 1992, p. 31.)

Storm water systems owned by state highway departments in low-population areas (under 100,000) are not required to be permitted. Appendixes to Part 122 indicate the incor­porated areas and unincorporated counties in the United States with sufficient population to require municipal storm water permits. This information is shown in Table 1.10.

Application requirements for a group permit for discharges from large and medium municipal storm sewers fall into two parts. Also, an annual report must be submitted, as dis­cussed later.

Storm Water Permits for Construction. EPA in 1990 established final regulations for controlling storm water runoff from specific categories of industries and activities (40 CFR 122, 123, and 124). Any discharger of, or person who proposes to discharge, a waste other than to a sewer system, or changes the character of a current discharge, is required to report this activity to the local enforcement agency (Dufour, op. cit., p. 75). Once reported, the agency will evaluate the discharge and may

• Issue waste discharge requirements.

• Waive discharge requirements for insignificant discharges such as well testing or con­struction dewatering (no waiver is permitted if the discharge is to surface waters).

• Prohibit the discharge if sufficiently protective discharge requirements cannot be met by the discharger.

Discharge requirements are issued through an NPDES permit that specifies conditions the discharger must meet. The conditions are based on the established water quality objec­tives and the capacity of the existing storm water drainage system or receiving waters to assimilate the discharge. Discharge limitations are usually expressed as a combination of quantitative and procedural specifications. CWA provides for three types of NPDES per­mits: individual, group, and general. Issuance of waste discharge requirements must be noticed for public comment and approved at a hearing of the local authority (Ibid., p. 74).

The primary industrial category in the regulation relevant to building and maintaining highways is “construction activities.” Construction activities, in this context, include clearing, grading, and excavating that result in the disturbance of 5 acres or more of land that is not part of a larger (nonhighway) construction project. Construction sites were tar­geted because studies showed that the runoff from construction sites has high potential for serious water quality impacts. Sediment runoff from construction sites may be 10 to 20 times that from agricultural lands. Non-point-source pollutants from construction sites include sediment, metals, oil and grease, nitrates, phosphates, and pesticides.

To obtain an NPDES construction permit, a notice of intent must first be filed request­ing permit coverage at least 48 hours before construction begins. The NOI contains the following information:

1. Owner of the site (legal name and address) and contact person’s name, title, and tele­phone number. This entity must have control over construction plans and specifications, the ability to make changes, and day-to-day operational control.

2. Construction site information—whether the construction is part of a larger project or the portion of the site that is impervious both before and after construction activities. Site location must be provided as latitude and longitude. Indicate whether endangered or threatened species or designated critical habitats are present, as well as whether the project is on Indian Country Lands.

3. Scheduled beginning and ending dates of construction.

4. Identification of the receiving body of water, and storm water drainage information including a site map.

5. Type of construction activity: transportation should be indicated if the project is a road­way; utilities should be indicated for the installations of sewer, electric, and telephone systems.

6. Material handling and management practices indicating the type of material to be stored and handled on site and the management practices to be used to control storm water pollution.

7. Regulatory status of the site, including approval status of the erosion or sediment control plan.

8. Signature of the owner of the site certifying that the information is accurate.

Most statewide NPDES permits for general construction activities require the permit holder to develop and implement a storm water pollution prevention plan (SWPPP) using either best available technology economically achievable (BAT), best conventional tech­nology (BCT), or best management practices (BMPs) to control pollutant discharge both during and after construction activities. Once prepared, the SWPPP will be maintained at the construction site by the highway department representative and made available on request by the local enforcement agency. All contractors and subcontractors working at the site are responsible for implementing the SWPPP. The SWPPP will generally include the following components:

1. Location, including a 1/4-mi vicinity map that shows nearby surface water bodies, drainage systems, wells, general topography, and location where storm water from the construction activities will be discharged, including MS4s.

2. A site map that indicates the total site area and total area to be disturbed. This map should indicate the location of the control practices to be implemented, areas where wastes and soils will be stored, drainage patterns for the site both before and after con­struction activity, areas of soil disturbance, areas of surface water, potential soil ero­sion areas, existing and planned paved areas, vehicle storage areas, areas of existing vegetation, and areas of postconstruction controls.

3. A narrative description of the construction site, project, and activities. This should include a description of the fill material and native soils at the construction site and the percentage of site surface area that is impervious both before and after construction activities.

4. A narrative description of toxic material used, treated, or disposed of at the construction site.

5. Identification of potential sources of storm water pollution, and name of receiving water.

6. Proposed controls and best management practices during construction, including description of

• State and local erosion sediment control requirements

• Source control practices intended to minimize contact between the construction equipment and materials and the storm water being discharged

• Erosion and sediment control procedures to be implemented

• Plan to eliminate or reduce discharge of other materials into the storm water

7. Proposed postconstruction waste management and disposal activities and planned controls, including a description of state and local erosion and sediment postclosure control requirements.

8. Estimated runoff coefficient for the site, estimated increase in impervious area follow­ing the construction, nature of fill, soil data, and quality of discharge.

9. List of the contractors and their subcontractors who will be working at the construction site.

10. Employee training.

11. Maintenance, inspection, and repair activities.

Control measures for sediment include grading restrictions, runoff diversion, application of straw bales and filter fabric, revegetation requirements, and retention basins. Control measures for other pollutants include roof drains, infiltration trenches, grassy swales to detain storm water to allow sediments to settle out, oil/grit separa­tors, detention basins, and proper management practices such as the proper applica­tion of fertilizers and pesticides.

Another approach used to implement the NPDES program for state highway agencies is to issue comprehensive permits for all relevant highway construction, maintenance, and operations activities in areas meeting the population requirements outlined in 40 CFR 122.26. The benefit of a comprehensive permit is the management efficiency of adminis­tering the permit from both the regulatory agency and highway department perspectives.

In California, for instance, the California Regional Water Quality Control Board (RWQCB) is responsible for issuing storm water discharge permits. The RWQCB in the San Francisco Bay area has issued a comprehensive NPDES permit for storm water dis­charged directly or through municipal storm drain systems to lakes, water supply reser­voirs, groundwaters, the Pacific Ocean, San Francisco Bay, San Pablo Bay, Suisun Bay, the Sacramento River Delta, or tributary streams or watercourses and contiguous water bodies in the San Francisco Bay region (District 4 and portions of District 10 of the California Department of Transportation, or Caltrans).

Provisions of the permit cover maintenance operations and include requirements to submit plans for maintenance activities that affect storm water discharges and to improve practices that will result in reduction of pollutants in discharges. Road sweeping plans, storm drains, catch basins, inlet and channel maintenance, and vegetation control plans are required. Caltrans must prepare storm water pollution prevention plans for maintenance facilities that cover such activities as vehicle and equipment maintenance, cleaning, fuel­ing practices, and storage and handling of construction materials, fertilizers, pesticides, paints, solvents, and other chemicals.

Under the provisions of the permit, Caltrans must rank construction activities on the basis of their potential impacts on receiving waters from pollutants in storm water dis­charges. Plans must be developed for erosion control, chemical and waste management, and postconstruction permanent features. Training is a key component of these plans.

The permit also encompasses permanent control measures for the management of storm water draining from Caltrans rights-of-way in areas meeting the population criteria. Consideration must be given to high-risk areas where spills may occur and must include a plan to reduce the pollutants discharged into the system over time. This portion of the permit requires Caltrans to develop mechanisms to control illegal dumping, to respond to accidental discharges, and to identify and control procedures for discharge in a category not expressly prohibited by the permit.

The RWQCB included specific provisions to assist in meeting water quality goals. For example, requirements of the permit include specific measures to reduce the mass load of copper in storm water discharges.

Monitoring plans and annual reports are also required in the NPDES permit and are gen­erally consistent with these provisions in standard construction and/or municipal storm water permits.

Sustainable storm water management practices have been evolving over the last 20 years, but it has been only during the last decade that the movement has gained momentum and designers are looking toward best management practice and low impact design solutions to storm water issues. These design concepts use the natural capacity of the environment to detain, filter, and reduce (through evaporation and transpiration) the runoff from a roadway facility. Relying on these natural systems, rather than engineered water conveyance and discharge infrastructure, can

• Reduce regulatory burden and time in gaining approval for the project.

• Improve the function of treatment plant—reduce combine sewer outfills.

• Improve the environment—using design measures to create wetlands and other habitat.

• Gain community buy-in.

• Reduce costs.

Wetlands Involvement (Executive Order 11990). Under Executive Order 11990, the fol­lowing procedures must be followed for any federal action that involves wetlands:

• An opportunity for early public involvement must be provided for actions involving wetlands. For those actions requiring either a FONSI or an EIS, any notices for a public hearing, or an opportunity for a hearing, must indicate if any alternatives are located in wetlands. At any hearing, the location of wetlands must be identified. A newspaper notice inviting written comments must be published prior to issuance of a categorical exclusion.

• Alternatives that would avoid wetlands must be considered, and if avoidance is not possible, measures to minimize harm to wetlands must be included in the action. Documentation of these avoidance requirements must be included in an EA or EIS.

• A wetlands-only-practicable-alternative finding must be prepared for actions requiring a FONSI or an EIS (FHWA Technical Advisory T6640.8A).

Floodplain Involvement (Executive Order 11988). Executive Order 11988 require addi­tional steps in the environmental review process for actions that encroach on floodplains. Specifically, the public must be given the opportunity for early review and comment, and notices must reference potential encroachments on the base floodplain. In addition, floodplain-only-practicable-alternative finding must be prepared for actions involving a significant encroachment (see FHWA Technical Advisory T6640.8A). This finding must be included in the final environmental document.

A floodplain evaluation must be prepared and summarized in the environmental docu­ment in accordance with federal regulation (23 CFR 650, Subpart A). This floodplain eval­uation should contain a project description, including a map of the project showing the base floodplain and all project encroachments, as well as alternatives to encroachment. A dis­cussion should be provided of the practicality of alternatives that would avoid longitudinal or significant encroachments.

The floodplain evaluation should be summarized in the EA or EIS. The portions of the evaluation pertaining to fish and wildlife, vegetation, wetlands, growth inducement, etc., are to be included in the respective sections of the EA or EIS. Summaries involving flood­plains in general, as well as hydraulics and risk, are to be included in a section entitled Floodplains.

Safe Drinking Water Act. The Safe Drinking Water Act (SDWA) was enacted in 1974 to protect the nation’s drinking water supply and protect public health through appropriate water treatment technologies. The SDWA applies to all of the more than 160,000 public water sys­tems in the United States. SDWA establishes maximum contaminant levels (MCLs), or stan­dards for the maximum safe levels of specific constituents in potable water. Important to highway engineers is the provision of SWDA that mandates protection of sources of drinking water. The SDWA requires the protection of drinking water and its sources: rivers, lakes, reservoirs, springs, and groundwater wells. The location of these resources, therefore, becomes an early consideration in the siteing and design phases of a project.

Federal Endangered Species Act. The Federal Endangered Species Act of 1973 (16 USC §§1531-1543) provides a means whereby the ecosystems upon which endangered species and threatened species depend may be conserved. It also provides a program for the con­servation of such endangered and threatened species. Section 7 of the act requires each fed­eral agency, in consultation with the Secretary of the Department of the Interior, to ensure that actions authorized, funded, or carried out by a federal agency do not jeopardize the continued existence of any endangered or threatened species or result in the destruction or adverse modification of habitat of such species unless such agency has been granted an exemption for such action.

For federal highway projects, a request is made to the U. S. Fish and Wildlife Service (FWS) regarding whether any species listed or proposed as endangered are present in the project area. If so, a biological assessment must be completed and reviewed by the FWS. The FWS will make a determination as to the impacts on critical habitat or on the species itself and whether the impacts can be mitigated or avoided. An exemption from the Endangered Species Act must be obtained where a project would result in impacts to endangered species.

The level of involvement with the endangered species process can vary widely from project to project, but will generally involve the following steps:

• Establish an area of potential environmental impact (APEI) and potential for conflict with endangered species.

• Once preliminary alternatives are selected, determine whether a request for a species list from the FWS is required and then request a list, through FHWA, if required.

• Perform and document a biological assessment.

• If there are no species present or there will be no effect, obtain FWS concurrence through FHWA before circulating the draft environmental document under NEPA.

• If the preferred alternative affects species, request conference or consultation with the FWS through FHWA, which must be completed before the final environmental docu­ment under NEPA can be approved.

Rivers and Harbors Act. The Rivers and Harbors Act of 1899 (33 USC 401 et seq. RHA) was enacted to protect navigation and the navigable capacity of the nation’s waters. Two provisions of the act have to potential to significantly affect highway projects proposed in or around U. S. harbors or rivers are

• Section 9 of the RHA, which requires a permit for the construction of bridges or cause­ways across navigable waters of the United States

• Section 10 of the RHA, which requires a permit for various types of work performed in navigable waters, including stream channelization, excavation, and filling

The permit jurisdiction is divided between two agencies. The Section 9 bridge permit is the responsibility of the USGS. Section 10 for construction activities performed in the water is within the jurisdiction of the USACOE. Although often issued together, this permit has independence from a permit issued under Section 404 of the Clean Water Act.

Federal Requirements Protecting Air Quality and Noise

Clean Air Act (42 USC §7401-7626). The 1970 amendments to the Clean Air Act (CAA) provided a comprehensive approach to regulating the nation’s air quality. The CAA addressed both mobile and stationary air pollution sources and required the EPA to set and enforce national ambient air quality standards (NAAQSs). The CAA has been amended several times since 1970. Amendments to the CAA that were adopted in 1990 were particularly extensive and included provisions for stricter mobile source emissions, as well as restrictions on emissions linked to stationary sources including hazardous or toxic pollutants.

EPA has overall authority for the implementation of CAA requirements. Pursuant to the CAA, EPA established primary and secondary NAAQSs for six pollutants: ozone, carbon

monoxide, sulfur dioxide, lead, nitrogen oxides, and particulate matter. The CAA also regulates hazardous air pollutants (HAPs) released by chemical plants, dry cleaners, print­ing plants, and motor vehicles.

States are responsible for meeting CAA objectives by developing state implementation plans (SIPs). SIPs integrate regulations with other measures designed to meet NAAQS and associated CAA requirements. Federal agencies must comply with the approved SIP of the state in which they are operating. Many SIPs include air quality goals that exceed federal requirements and carry their own set of penalties and fines for noncompliance.

Current provisions of CAA relevant to highway engineering are included in Title I (Attainment and Maintenance of NAAQS), Title II (Mobile Sources), and Title VII (Enforcement). Title I addresses air pollution control requirements for “nonattainment areas,” (i. e., those metropolitan areas in the United States that have failed to meet NAAQSs.) Ozone is the most widespread pollutant in nonattainment areas. Therefore, the focus of controls in these areas is on controlling the volatile organic compounds (VOCs) and nitrogen oxides that are precursors to the formation of ozone. Title II regulates tailpipe emissions from motor vehicles and sets emission limitations for carbon monoxide,

hydrocarbon, and nitrogen oxides. Provisions for enforcement under Title VII include fines and terms of imprisonment. Federal violations prosecuted by EPA may result in civil penal­ties of up to $25,000 per day and criminal enforcement if the violator fails to abate on notice [42 USC §7413(b)].

If a SIP is not effective in achieving NAAQSs in a nonattainment area, EPA may pre­pare an implementation plan of its own and/or impose construction bans on stationary sources, or withhold EPA-approved federal funds (such as transportation improvement grants) targeted for the state.

Transportation Conformity. The CAA required EPA to promulgate rules to ensure that federal actions do not impede efforts to attain or maintain compliance with the NAAQS. These rules require that metropolitans and statewide transportation plans conform to CAA requirements. These transportation conformity regulations apply to highways.

The transportation conformity rules published under 40 CFR 93, address this requirement with respect to actions of certain transportation agencies, including funding or approvals, that involve projects in nonattainment and maintenance areas, (i. e., areas that were previously des­ignated as nonattainment but currently in compliance with the NAAQS). The transportation conformity rule established the criteria and procedures by which the FHWA, the FTA and metropolitan planning organizations (MPOs) determine the conformity of federally funded or approved highway and transit plans, programs, and projects to SIPs. Conformity ensures that transportation plans, programs, and projects do not result in new air quality violations, worsen existing violations, or delay timely attainment of the NAAQS.

Noise Control Act (NCA) 42 USC §4901-4918. The Noise Control Act (NCA) was enacted to control noise emitted from human activity. The NCA include two requirements that are relevant to highway engineering: (1) the required developing of state and local pro­grams to control noise, and (2) the required controlling the sources of noise of surface trans­portation and construction activities.

The NCA also created the EPA Office of Noise Abatement and Control (ONAC). ONAC promulgated regulations to implement the NCA (40 CFR 201 through 211). Noise limits for motor vehicles involved in interstate commercial activities are identified in 40 CFR 202. While noise emissions from construction equipment and compressors are regu­lated by 40 CFR 204. Noise limits and measurement procedures for trucks over 10,000 lb and motorcycles are included in 40 CFR 205.

Control of highway noise is currently under the jurisdiction of FHWA. FHWA noise reg­ulations are found in 23 CFR 772 and include the FHWA Noise Abatement Criteria (NAC). The NAC include maximum noise levels for various of land uses from adjacent highways. When highway noise levels approach or exceed the NAC, or when highway noise signifi­cantly increases above existing noise levels, noise abatement measures must be considered. FHWA allows individual states to define “approach” and “significant increase.” Typically, “approach” means within 1 or 2 dB and “significant increases” are typically defined as increases of 10 or 15 dB above existing noise levels.

FEDERAL REQUIREMENTS GOVERNING RESOURCE-SPECIFIC ENVIRONMENTAL ASPECTS

In addition to the federal requirements governing the planning and implementation of high­way projects, a number of federal statutes and regulations have been promulgated to pro­tect the environment. The responsibility and authority associated with these requirements are assigned to a number of federal agencies, or delegated to the states. A listing of key fed­eral environmental requirements is provided in Table 1.8.

Environmental requirements are also included in a number of executive orders issued by the President of the United States that mandate policy on specific issues, including orders concerning the protection of wetlands, floodplains, significant cultural resources, disadvantaged and minority populations, marine resources, and energy supply. Relevant executive orders are included in Table 1.9.

State Environmental Review Legislation

Fifteen states and the District of Columbia and Puerto Rico have enacted environmental policy acts, which, because they are largely modeled on NEPA, are collectively referred to as “Little NEPAs.” A list of these statutes is provided in Table 1.7. Highway projects may be affected by these state-specific environmental requirements, which, in general, follow or expand upon federal objectives and programs. In some instances, the state defers to the NEPA process, while, in others, the state reviews proceed as independent but parallel and coordinated efforts. In addition, increasingly, states are being given powers to implement federal programs, leading to their further involvement in the environmental review of high­way projects. For example, under SAFETEA-LU, Congress provided for a process whereby some states could assume responsibilities for all environmental compliance for highway projects, including NEPA.

The Environmental Impact Assessment Process under NEPA

An outline of the steps in the NEPA process is presented in the following discussion and illustrated in Fig. 1.1.

Determination of the Level of Documentation Needed to Comply with NEPA.

Highway projects are usually initiated by a state or local transportation agency. If it is anticipated that a major federal action is required to implement a project, it must com­ply with NEPA. Conversely, projects that do not require a major federal action do not require review under NEPA. These minor actions include projects that are “categori­cally excluded” from detailed review under NEPA and for which a minimal level of environmental documentation is required. A list of categorical exclusions is provided

in Tables 1.2 and 1.3. The following are examples of actions that would trigger the need to comply with NEPA.

• The proposed use of federal funds for the planning, engineering, or construction of a pro­ject, or for needed right-of-way acquisition

• Modifications to an existing interstate highway

• Modifications to a non-interstate access-controlled highway that affects the right-of-way previously financed with federal funds

TABLE 1.2 Actions Categorically Excluded from Further Review by FHWA

1. Activities that do not involve or lead directly to construction

2. Approval of utility installations along or across a transportation facility

3. Construction of bicycle and pedestrian lanes, paths, and facilities

4. Activities included in the state’s highway safety plan under 23 USC §402

5. Transfer of federal lands pursuant to 23 USC §317 when the subsequent action is not an FHWA action

6. Installation of noise barriers or alterations to existing publicly owned buildings to provide for noise reduction

7. Landscaping

8. Installation of fencing, signs, pavement markings, small passenger shelters, traffic signals, and railroad warning devices where no substantial land acquisition or traffic disruption will occur

9. Emergency repairs under 23 USC §125

16. Program administration, technical assistance activities, and operating assistance to transit authorities to continue existing service or increase service to meet routine changes in demand.

17. Purchase of vehicles by the applicant where the use of these vehicles can be accommodated by existing facilities or by new facilities which themselves are within a categorical exclusion

18. Track and railbed maintenance and improvements when carried out within the existing right – of-way

19. Purchase and installation of operating or maintenance equipment to be located within the tran­sit facility and with no significant impacts off the site

20. Promulgation of rules, regulations, and directives

If a project is subject to NEPA, a determination must then be made regarding the level of analysis and process to be completed to comply with NEPA. The type of environmental documentation that is required must be made in consultation with FHWA, which, in turn, coordinates the review of a proposed action with other involved federal agencies. Based on coordination with FHWA, a project could require one of the three levels of environmental documentation:

• Documentation supporting the project status as a categorical exclusion (CE).

• Projects for which an environmental assessment is required to make a final determination of whether an Environmental Impact Statement is required.

• Projects for which an environmental impact statement is required.

TABLE 1.3 Actions Generally Excluded from Further NEPA Review But Subject

to FHWA Approval

1. Modernization of a highway by resurfacing, restoration, rehabilitation, reconstruction, adding shoulders, or auxiliary lanes

2. Highway safety or traffic operations improvement projects, including the installation of ramp­metering control devices and lighting

3. Bridge rehabilitation, reconstruction, or replacement or the construction of grade separation to replace existing at-grade railroad crossings

4. Transportation corridor fringe parking facilities

5. Construction of new truck weigh stations or rest areas

6. Approvals for disposal of excess right-of-way or for joint or limited use of right-of-way, where the proposed use does not have significant adverse impacts

7. Approvals for changes in access control

8. Construction of new bus storage and maintenance facilities in areas used predominately for indus­trial or transportation purposes where such construction is not inconsistent with existing zoning and located on or near a street with adequate capacity to handle anticipated bus and support vehi­cle traffic

9. Rehabilitation or reconstruction of existing rail and bus buildings and ancillary facilities where only minor amounts of additional land are required and there is not a substantial increase in the number of users

10. Construction of bus-transfer facilities (an open area consisting of passenger shelters, boarding areas, kiosks, and related street improvements) when located in a commercial area or other high-activity center in which there is adequate street capacity for projected bus traffic

11. Construction of rail storage and maintenance facilities in areas used predominatly for industrial or transportation purposes where such construction is not inconsistent with existing zoning and where there is no significant noise impact on the surrounding community

12. Acquisition of land for hardship or protective purposes

Source: Adapted from 23 CFR 771.117(d).

A determination of the extent of environmental documentation is based on a preliminary environmental evaluation of a proposed action to determine whether:

• The proposed action falls within the definitions of projects that are categorically excluded from NEPA review.

• The proposed action has the potential to result in one or more significant environmental impacts.

• Measures are reasonably available that could mitigate potential environmental effects thereby eliminating the potential for significant environmental impacts.

• The project has unusual level of public controversy that may warrant preparation of an EIS.

Categorical Exclusions. CEQ regulations implementing NEPA (40 CFR 1508.4) require that each federal agency identify the types of actions under its purview that would not individually or cumulatively result in significant environmental impacts. These projects, designated as categorical exclusions, are exempt from the need to pre­pare an EA or EIS.

FHWA has identified two sets of projects that may be categorically excluded from detailed review under NEPA. The first group of actions is found in 23 CFR 771.117(c) and

is provided in Table 1.2. These are actions that have been categorically found not to result in significant adverse environmental impacts. The second group of actions is found in 23 CFR 771.117(d) and is provided in Table 1.3. These include actions that have been found generally not to result in significant adverse environmental impacts, but for which FHWA must make a final determination.

When satisfied that the project meets one or more exclusion criteria and that other envi­ronmentally related requirements have been met, FHWA will indicate approval by signing a Categorical Exclusion form. A copy of documentation required to support this determi­nation must be sent to FHWA by the sponsoring agency.

In certain cases, FHWA has reached agreement with sponsoring agencies on the treat­ment of very routine, repetitive projects with little or no environmental impact implica­tions. Such projects may be processed on the basis of a “programmatic” categorical exclusion if certain specified conditions are met. Use of this programmatic process is sub­ject to annual review by FHWA.

Classification of a project as a categorical exclusion does not exclude a project from the requirements of other federal environmentally related processes. These requirements must be met before FHWA will make an exclusion determination. In addition, Congress may, at its discretion, also exempt a specific federal project or program from NEPA through spe­cific legislation.

Environmental Assessments. An EA is conducted for projects that are not categorically excluded and for which it is not clear whether an EIS is required. The primary purpose of an EA is to help FHWA decide whether an EIS is needed. Consequently, an EA should pro­vide the evaluations critical to determining whether a proposed action would result in a significant impact on one or more of the environmental resources considered under NEPA, thereby necessitating a more complete analysis in an EIS. If it is determined that a proposed action does not have the potential to result in one or more significant environmental impacts, then FHWA will issue a Finding of No Significant Impact (FONSI), thereby ter­minating the environmental review process under NEPA. If it is determined that a proposed action has the potential to result in one or more significant impacts, then FHWA has the option to require that an EIS be prepared.

Contents and Format of an EA. The contents of an EA are determined through agency and public scoping, preliminary data gathering, and field investigation. These steps will identify potentially affected resources and the level of analysis that is neces­sary to identify whether an action would have the potential to result in a significant envi­ronmental impact.

The EA should be a concise document, including only the data and technical analyses needed to support decision making, and be focused on determining whether the proposed action would have a significant effect on the environment. It is not necessary to provide detailed assessments of those resources for which significant environmental impacts are very unlikely.

In addition to a cover sheet and table of contents, the following elements should be included in an EA:

• Purpose and need for the proposed action

• Project description and alternatives

• Environmental setting, impacts, and mitigation

• Comments and coordination

• Appendices (as necessary)

• Section 4(f) evaluation (if required)

• EA revisions (if required)

Purpose and Need for the Proposed Action. A succinct description of the purpose and need for the proposed action should be provided at the beginning of the EA. The need for the project should be based on an objective evaluation of current information and future anticipated conditions. This section of the EA should identify the transportation problem(s) or other needs which the proposed action is intended to address (40 CFR 1502.13). The sec­tion should clearly demonstrate that a need exists and should define the need in terms understandable to the general public. The statement of purpose and need will form the basis for identifying of reasonable alternatives and in selecting a preferred alternative.

Consistent with joint FHWA and Federal Transit Administration (FTA) guidance (July 23, 2003 Joint Memorandum from Mary E. Peters, administrator of FHWA and Jennifer L. Dorn, administrator of FTA), the Purpose and Need Statement must be as con­cise and understandable as possible. Although it serves as the cornerstone for the subse­quent identification and evaluation of alternatives, it should not specifically discuss any alternative or range of alternatives, nor should it be so narrowly drafted that it unreasonably points to a single solution, thereby circumventing necessary environmental review before a selection is made. In general, the “need” for an action should be defined as the trans­portation system deficiencies that will be addressed by the action, while the “purpose” for the action should be described as the objectives that will be met to address the deficiencies. Table 1.4 identifies the types of information that could be incorporated into the EA to demonstrate the need for a proposed action.

Project Description and Alternatives. Included in this section of the EA should be a project description written in clear, nontechnical language. It should include the location and geographic limits of the project and its major design features and typical sections; a location map (district, regional, county, or city map depicting state highways, major roads, and well-known features to orient the reader to the project location); a vicinity map

TABLE 1.4 Information to Establish Need for Highway Projects

Project status: Briefly describe the project history including actions taken to date, other agencies and governmental units involved, action spending, schedules, etc.

System linkage: Is the proposed project needed as a “connecting link”? How does the project fit in the transportation system?

Capacity: Is the capacity of an existing facility inadequate for the present and projected traffic? Would the proposed project provide needed additional capacity? What is the level(s) of service for existing and proposed facilities?

Transportation demand: Is the project identified in an adopted statewide or metropolitan transportation plan as needed to meet current or projected demand?

Legislation: Is there a federal, state or local governmental mandate for the action?

Social demands or economic development: Is the project needed to address projected economic development or changes in land use?

Modal interrelationships: Is the proposed project needed to interface with and complement airports, rail and port facilities, or mass transit services?

Safety: Is the proposed project needed to correct an existing or potential safety hazard? Is the

existing accident rate excessively high compared to that of similar facilities in the region or state?

Roadway deficiencies: Is the proposed project needed to correct existing roadway deficiencies (e. g., substandard geometrics, load limits on structures, inadequate cross-section, or high maintenance costs)?

(detailed map showing project limits and adjacent facilities); current status of the project including its relation to regional transportation plans, regional transportation improvement programs, congestion management plans, and the state transportation improvement pro­gram; proposed construction date; funding source(s); and the status of other projects or pro­posals in the area. For projects that include more than one type of improvement, the major design features of each type of improvement should be included.

The description of the project should clearly indicate the independence of the action by

• Identifying and providing the basis for establishing the “logical termini” (project limits) of the action

• Establishing the separate utility of the action from other actions of the agency

• Establishing that the action does not foreclose the opportunity to consider other actions

• Confirming that the action does not irretrievably commit federal funds for closely related projects

Reasonable alternatives to the project should be discussed, including consideration of a no-action option, which is mandated under both CEQ and FHWA regulations. The EA may either discuss (1) the preferred alternative and identify any other alternatives considered or

(2) if a preferred alternative has not been identified during previous planning studies, the alternatives under consideration. The EA does not need to evaluate in detail all reasonable alternatives for the project, and may be prepared for one or more build alternatives.

Project alternatives can be classified into two types: viable, and those studied but no longer under consideration. Viable alternatives should be described in sufficient detail to compare their effectiveness against the proposal in meeting the project purpose and need, and to assess potential impacts and estimate cost. Alternatives no longer under considera­tion should be explained briefly and the reasons provided for their elimination.

Environmental Setting, Impacts, and Mitigation. The EA should include a description of the environmental setting in which the proposed action would be located. The descrip­tion should be succinct and maximize the use of visual displays to reduce the need for extensive narrative. Beyond a general description of contextual background, the discussion should focus on those features that have the greatest potential to be significantly affected by the proposed action.

The EA should discuss any social, economic, and environmental impacts whose sig­nificance is uncertain. The level of analysis should be sufficient to adequately identify the impacts and available measures to mitigate impacts, and to address known and fore­seeable public and agency concerns. Impact areas that do not have a reasonable possibil­ity for individual or cumulative environmental impacts need not be addressed. The reasons for determining why any impacts are not considered to be significant should be provided.

If more than one alternative is involved, the evaluation must identify the impacts asso­ciated with each alternative being evaluated. The EA should identify the technical studies and backup reports used in making the assessment and indicate where they are available. A list of environmental resource categories to be considered in both EAs and EISs is included in Table 1.5.

Feasible measures that reduce or eliminate potential impacts of a proposed action should be identified. Measures may be presented as potential commitments that may be selected for implementation by the lead agency. Alternatively, these measures can be incor­porated as elements of the proposed action, thus avoiding impacts. Measures to mitigate impacts may diminish the intensity of project effects to the point that they would not be considered to be significant, and could make the project eligible for a FONSI.

Based on the results of these evaluations, a determination is made of whether the antic­ipated effects of the project represent a significant environmental impact thereby requiring

the preparation of an EIS. This determination is based on a review of the context and intensity of the impact. Context refers to the setting within which the proposed project is being developed. Intensity refers to the severity of an impact and will vary by resource type.

Factors to consider in determining intensity of an impact include

• The degree to which the action may affect public health or safety.

• The degree to which the effects on the quality of the human environment may result in a significant level of public controversy.

• Whether the action may result in cumulatively significant impacts when added to the effects of other planned and programmed projects and activities separate from the pro­posed action.

• Whether the action has the potential to violate one or more federal, state, or local laws or standards intended to protect the environment.

Factors to be considered in determining the context include

• Unique characteristics of the geographic area such as proximity to public, park lands, prime farmlands, wetlands, wild and scenic rivers, or ecologically critical areas.

• The degree to which the action may adversely affect districts, sites, highways, structures, or objects listed on or eligible for listing on the National Register of Historic Places.

• The degree to which the action may adversely affect threatened or endangered species of their habitat that has been determined to be critical under the Endangered Species Act of 1973.

Comments and Coordination. Determination of the need for an EIS or whether the FHWA can issue a FONSI can only be made after the EA has been made available for agency and public review. This section of the EA should summarize the efforts taken to coordinate with agencies and the public, identify the key issues and pertinent information received through these efforts, and list the agencies and members of the public consulted.

Public involvement is an essential element of the NEPA process, and the proposing agency must take proactive steps to encourage and provide for early and continuing public participation in the decision-making process [40 CFR 1506(a)]. Opportunities for public involvement are provided at several stages during the development of NEPA documents, such as at the publication of the notice of intent (NOI) to prepare an EIS, during the process used to scope the environmental document, and during the process afforded to agencies and the public to review the environmental document.

Opportunity for the public to review and comment on the completed (draft) EA occurs upon publication of a notice of availability of the draft document. Such notice may be pub­lished in local newspapers or other local print media, presented in special newsletters, pro­vided to community and business associations, placed in legal postings, and presented to interested Native American tribes, if appropriate. For an EIS, publication of such notice is also required in the Federal Register. Notices and other public announcements regarding the project should be sent individually to those who have expressed an interest in a spe­cific action.

Early incorporation of public input on project alternatives and issues dealing with social, economic, and environmental impacts helps in deciding whether to prepare an EIS, in determining the scope of the document, and in identifying important or controversial issues to be considered. When impacts involve the relocation of individuals, groups, or institutions, special notification and public participation efforts should be undertaken. Early and ongoing public involvement will assist in gaining consensus on the need for the action and in identifying and screening alternatives.

A public hearing is not mandated to receive comment on an EA but is required for pub­lic review of a draft EIS. The proposing agency must provide for one or more public hear­ings to be held at a convenient time and place for federal actions that require significant amounts of right-of-way acquisition, substantially change the layout or function of con­necting roadways or of the facility being improved, have substantial adverse impact on abutting properties, or otherwise have a significant social, economic, or environmental effect [23 CFR 771.111(h)(2)(iii)].

During public hearings, the public should be provided with information on the pro­ject’s purpose and need and with how the project relates to local and regional planning goals, the major design features of the project, its potential impacts, and the reasonable alternatives under consideration including the no-action alternative. Areas of special interest to the public, such as needed right-of-way acquisition and the proposed displace­ment and relocation of existing uses, should be carefully explained, as should the agen­cy’s procedures and timing for receiving oral and written public comments [23 CFR 771.111(h)(2)(v)]. The public comment period for a draft EIS is at least 45 days. All pub­lic comments received during the public comment period, including during public hear­ings must be documented.

Appendices (if any). Appendices to the EA should include the analytical information that substantiates the principal analyses and findings included in the main body of the document.

Section 4(f) Evaluation (if any). As described in Art. 1.2 of this chapter, a Section 4(f) evaluation may be required if a project would require the use of land from a significant pub­licly owned public park, recreation area, or wildlife and waterfowl refuge, or any signifi­cant historic site. If a Section 4(f) evaluation is required, it may be included as a section within the EA. If included within the EA, a separate “avoidance alternatives evaluation” need not be repeated in the EA. In all cases, the Section 4(f) evaluation must be circulated for review in conformance with 23 CFR 771.135(i) requirements.

EA Revisions. An EA should be revised subsequent to public review to (1) reflect changes in the proposed action, impact assessment, or mitigation measures resulting from comments received on the EA, (2) include any necessary findings, agreements, or determi­nations made as a consequence of the concurrent reviews under Section 4(f) or other reg­ulatory requirements, and (3) include a copy of pertinent substantive comments received on the EA and appropriate responses to the comments.

Finding of No Significant Impact. After review of the EA and any other appropriate information, the FHWA may determine that the proposed action would not result in any significant impacts, and issue a FONSI. The FONSI should briefly present the reasons why the proposed action would not have a significant effect on the human environment or require the preparation of an EIS. The FONSI should document compliance with NEPA and other applicable environmental requirements. If full compliance with all these other requirements is not possible by the time the FONSI is published, the FONSI should docu­ment consultation with the affected agencies to date and describe how and when the other requirements will be met.

There is no requirement to publish a record of decision (ROD) for a FONSI, nor is there a legally mandated requirement to distribute the FONSI. However, the FHWA must send a notice of availability of the FONSI to federal, state, and local government agencies likely to have an interest in the undertaking and the state intergovernmental review con­tacts [23 DFR 771.121(b)]. It is encouraged that agencies that have comments on the EA (or requested to be informed) be advised on the project decision and the disposition of their comments, and be provided a copy of the FONSI.

Environmental Impact Statement. A federal agency must prepare an EIS if it is propos­ing a major federal action that would significantly affect the quality of the human environ­ment (40 CFR §1501.7). The regulatory requirements for an EIS are more extensive than the requirements for an EA. The steps to be followed in preparing an EIS are depicted in Fig. 1.1.

Once the lead agency determines that an action would result in a significant measur­able impact, development of a draft enviornmental impact statement (DEIS) is initiated through a public and agency notification and scoping process focused on early identifi­cation of the major issues of concern and alternatives for study. This process includes confirmation of FHWA as the agency to lead the environmental review process, identifica­tion of cooperating agencies, distribution of a letter of initiation of the environmental process from the sponsoring agency, publication of a notice of intent to prepare an EIS, invitation to agencies to become participating agencies in the environmental review process, and completion of scoping activities. Each of these steps is described in the fol­lowing discussion.

Lead Agency Determination. In accordance with Section 6002 of SAFETEA-LU, DOT is designated as the federal lead agency for the “environmental review process” for any surface transportation project that requires a DOT approval. The environmental review process includes both NEPA and other reviews. The lead agency is responsible for taking actions within its authority to facilitate the resolution of the environmental review process. It also is responsible for preparing the required NEPA document for the

project, or ensuring that one is prepared. Other federal agencies that have jurisdiction by law, or that have special expertise with respect to any environmental issue that should be addressed in the EIS may be a cooperating agency upon request of the lead agency. An agency may also request that the lead agency designate it as a cooperating agency. Each cooperating agency must (1) participate in the NEPA process at the earliest possible time,

(2) participate in the scoping process described below, (3) assume on request of the lead agency responsibility for developing information and preparing environmental analyses including portions of the EIS concerning issues which the cooperating agency has spe­cial expertise, and (4) make staff available to enhance the lead agency’s interdisciplinary capability.

Dissemination of Letter of Initiation. In accordance with Section 6002 of SAFETEA – LU, a project sponsor has the responsibility to notify DOT that the environmental review process for a project “should be initiated.” This notice of initiation, which can take the form of a letter or other form of notice, should identify the type of work, termini, length, and gen­eral location of the project. It should also identify any federal approvals that the project sponsor believes will be necessary, including all anticipated environmental reviews, per­mits, and consistency determinations.

Publication of Notice of Intent. The EIS process begins with the publication of a notice of intent (NOI) stating the agency’s intent to prepare an EIS for the proposed action. The NOI is published in the Federal Register, and provides basic information on the proposed action in preparation for a subsequent “scoping process.” The NOI should include a description of the purpose and need for the proposed action similar to that included in an EA. In addition, it includes a brief description of the proposed action and possible alternatives, and a descrip­tion of the process proposed by the sponsoring agency to identify the scope of the EIS. This should include any proposed scoping meetings and other methods proposed for public involvement in the environmental review process. The NOI should also identify the agency point of contact for the project, who can respond to questions concerning the proposed action and the NEPA process. The NOI should emphasize the lead agency’s commitment to col­laborate with others interested in the proposed action and to describe how it intends to engage interested parties throughout the analysis. The publication of the NOI in the Federal Register can be supplemented by issuing other forms of notice such as announcements on websites, newspapers, newsletters, and other forms of media. The format and content of the notice of intent are included in FHWA Technical Advisory T6640.8A.

Invitation to Participating Agencies. In addition to publication of an NOI, Section 6002 of SAFETEA-LU requires that the lead environmental agency designate as “participating agencies” (a new term created under SAFETEA-LU) all other govern­mental agencies—federal or nonfederal—that may have an interest in the project, and invite them to participate in the environmental review process for the project. Such desig­nation and invitation should occur as early in the environmental review process as is practicable. Any federal agency that is invited to participate in the process must accept the invitation unless that agency notifies the lead agency in writing by the deadline speci­fied in the invitation that (1) it has no jurisdiction or authority over the project, (2) it has no information or expertise relevant to the project, and (3) it does not intend to submit comment on the project.

Section 6002 of SAFETEA-LU further mandates that the lead agency must establish a plan for coordinating public and agency participation in the environmental review process, including for all federal environmental reviews for the project, not just DOT reviews. Optionally, the lead agency may establish a schedule for completion of the environmental review process after consultation with all participating agencies and the state and project sponsor. SAFETEA-LU directs “each federal agency, to the maximum extent practicable,” to (1) carry out all reviews required under other laws concurrently with the review required in NEPA, and (2) formulate and implement mechanisms to enable the agency to ensure the

completion of the environmental review process in a “timely, coordinated, and environ­mentally responsible manner.”

Scoping. “Scoping” is an early and open process for determining the breadth of issues to be addressed in an EIS, the range of alternatives to be considered, and the methods to be applied in evaluating the effects of an action. The objectives of scoping are to

• Invite the participation of affected federal, state, and local agencies, any affected Indian tribe, and other interested persons (including those who might not be in accord with the action on environmental grounds).

• Identify and eliminate from detailed study the issues that are not significant or that have been covered by prior environmental review.

• Allocate assignments for preparation of the EIS among the lead and cooperating agencies.

• Identify other environmental review and consultation requirements so FHWA and cooper­ating agencies may prepare other required analyses and studies concurrently with the EIS.

• Indicate the relationship between the timing of the preparation of environmental analy­ses and the planning and decision-making schedule.

Notification and implementation of scoping is achieved through public agency involve­ment procedures required by 23 CFR 771.111.

Preparation of the Draft Environmental Impact Statement (DEIS). The principal pur­pose of the DEIS is to disclose to the decision makers and the public the probable impacts of reasonable alternative that have the potential to meet the purpose and need of a proposed action. Responsible decisions can be then made after public review and comment based on an assessment of the degree to which competing alternatives meet the need for the action and by balancing their relative environmental, social, and economic impacts.

Preparation of the DEIS should begin at the earliest practical time. A key element should be the early exploration of alternatives and their relative ability to meet the purpose and need for the proposed action. This will assist in identification of reasonable alternatives and allow early coordination with cooperating and responsible agencies.

The DEIS should be concise and include succinct statements, evaluations, and descrip­tions of conclusions. Lengthy, encyclopedic discussions of subject matter diffuse the focus of the document from its analytical purpose. The document should be easily understood by the public and written to emphasize the significant environmental impacts of competing alternatives. Discussions of less significant impacts should be brief, but sufficient to demonstrate that due consideration was given and more detailed study not warranted.

CEQ regulations emphasize brevity and stress the importance of focusing on significant issues and avoiding detailed discussion of less important matters. Normally, EISs should be less than 150 pages, or less than 300 pages if the action is unusual in scope and complexity. Exhibits (charts, tables, maps, and other graphics) are useful in reducing the amount of nar­rative required. Adequacy of a DEIS is measured by its functional usefulness in decision making, not by its size or amount of detail. This is especially applicable in the executive summary of the document, where items relating to alternatives and their impacts and related mitigation can be presented in a matrix format, thereby minimizing the need for narrative.

Contents and Format of the Draft EIS. In accordance with 40 CFR 1502.10 and FHWA Technical Advisory T6640.8A, an EIS should be prepared in accordance with the follow­ing outline unless compelling reasons to do otherwise are given by the proposing agency:

• Cover sheet

• Executive summary

• Title page

• Table of contents

• Purpose and need for the proposed action

• Alternatives

• Affected environment

• Environmental consequences

• Mitigation measures

• List of preparers

• List of who received copies

• Appendixes

• Index

Cover Sheet. The cover sheet should clearly indicate the name of the project, its loca­tion, date of publication of the DEIS, and the responsible sponsoring and environmental lead and cooperating agencies.

Executive Summary. A summary should be given that provides an overview of the entire DEIS and be no greater than 10 to 15 pages in length. The summary should include the following information:

• Briefly describe the proposed project, including the route, termini, type of facility, num­ber of lanes, length, county, city, and state, along with significant appurtenances, as appropriate.

• List other federal actions required for implementation of the project, including required permits. Also describe other major actions proposed by other governmental agencies in the same geographic area as the proposed project.

• Summarize all reasonable alternatives considered.

• Summarize the major environmental impacts of each alternative, both beneficial and adverse.

• Identify proposed measures to reduce or avoid identified impacts.

• Briefly describe any areas of concern (including issues raised by agencies and the public) including any important unresolved issues.

Title Page. The title page should identify the name of the proposed action, and its geographic limits and location, the date of the DEIS, and any relevant report number identified by the sponsoring agency and FHWA. The proposing agency must be clearly identified, including the name, address, and telephone number of a primary contact person. All agencies that serve as cooperating agencies should also be identified. A brief one paragraph abstract should be included, providing a description of the proposed action and its alternatives, a summary of significant impacts, and major mitigation mea­sures. The title page should also identify the date by which comments on the DEIS must be received.

Table of Contents. A table of contents should be included in the document and con­sider all areas of concern identified during the scoping process.

Purpose and Need of the Proposed Action. The DEIS should include a description of the purpose and need for the proposed action. The information provided should be similar to that provided in an EA, as described earlier in this chapter.

Alternatives. The lead agency must “objectively evaluate all reasonable alterna­tives, and for alternatives which were eliminated from detailed study, briefly discuss the

reasons for their having been eliminated” (40 CFR §1502.14). Reasonable alternatives are those that substantially meet the purpose and need for the proposed action, and include those that are practical or feasible from the technical and economic standpoint, rather than simply desirable from the standpoint of the applicant or the public. Agencies are obligated to evaluate all reasonable alternatives or a range of reasonable alternatives in enough detail so that a reader can compare and contrast the environmental effects of the various alternatives.

Both improvement of existing highways and facilities on new locations should be con­sidered, as appropriate to the need for the action. A representative number of reasonable alternatives must be presented and evaluated in detail in the DEIS. For most major projects, there is a potential for a large number of reasonable action alternatives. Only a representa­tive number of the most reasonable approaches, covering the full range of alternatives, should be presented. The number of reasonable alternatives will depend on the project loca­tion and pertinent project issues. Each alternative should be briefly described using maps or other visual aids such as photographs, drawings, or sketches. A clear description should be presented of the concept, major design features, termini, location, and costs for each alternative. More detailed design of some aspects may be necessary for one or more alter­natives to evaluate impacts or mitigation measures, or to address issues raised by other agencies or the public. However, equal consideration must be given to all alternatives. All reasonable alternatives considered should be developed to a comparable level of detail in the draft EIS so that their comparative merits may be evaluated. Where a preferred alter­native has been identified, it should be so indicated. The DEIS should include a statement that the final selection of an alternative will not be made until the impacts of the alterna­tives and public comments on the DEIS have been fully evaluated. Where a preferred alter­native has not been identified, the DEIS should state that all reasonable alternatives are under consideration and that a decision will be made only after the impacts of the alterna­tives and comments on the DEIS have been fully evaluated.

Both CEQ and FHWA regulations implementing NEPA require consideration of a “no-action” alternative. The no-action alternative is the condition that would occur if FHWA did not implement the proposed action, but may be different from the existing con­dition due to implementation of other actions separate from those of the proposed action if the proposed action was not authorized. For highway projects, the no-action alternative would at least include those reasonably foreseeable maintenance and safety actions required to continue operation of the facility under consideration.

Affected Environment. This section of the DEIS describes in concise terms the social, economic, and environmental setting for the alternatives under consideration. The limits of the study area(s) should be based on an assessment of the extent of potential impact for each impact category. Impact categories should include those listed in Table 1.5. Only aspects of the setting relevant to assessing the environmental impacts of proposed alternatives should be discussed in detail, with other descriptions limited to that necessary to provide context.

Environmental Consequences. The major significant impacts of the project should be discussed in detail in the environmental consequences section for each of the categories for which a description of the affected environment is provided. The analysis of impacts should consider all issues raised during the project’s public and agency-scoping process. The analysis must include consideration of the full range of short – and long-term, and direct, indirect, and cumulative effects of the preferred alternative, if any, and of the reasonable alternatives identified in the alternatives section of the DEIS. Effects to be considered include ecological, aesthetic, historic, cultural, economic, social, and public health impacts, whether adverse or beneficial (40 CFR §§1508.7, 1508.8).

Mitigation Measures. This section of the DEIS should specify measures to lessen the adverse environmental impacts of alternatives identified in the environmental consequences

section of the DEIS. For an impact mitigation measures to be considered usable it must be effective, economically feasible and the agency must be capable of and committed to implementing the measure. Under CEQ regulations, mitigation can be achieved by avoid­ing the adverse impact, minimizing the adverse effect by reducing the scope of the project, implementing a program to reduce the impact over time, or compensating for the impact by replacing or providing substitute resources.

List of Preparers. A list should be provided of the names and appropriate qualifica­tions (professional license, academic background, certification, professional working expe­rience, and special expertise) of the persons who were principally responsible for preparing the DEIS or substantial background papers. The list should include any project sponsor, FHWA and consultant personnel who had primary responsibility for preparing or review­ing the DEIS.

DEIS Distribution List. The draft EIS must list the names and addresses of the agen­cies and organizations that were sent copies of the DEIS for review.

Comments and Coordination. The draft EIS should contain pertinent correspondence summarizing public and agency coordination, meetings, and other pertinent information received.

Glossary and Abbreviations. A glossary and list of abbreviations should be included as an aid to those not familiar with the project development process and technical issues being considered in the DEIS.

References and Bibliography. A clear, concise listing of references and biblio­graphical material should be included.

Appendices. Appendices should contain the reports and documents that support the findings of the DEIS. Detailed technical discussions and analyses that substantiate the con­cise statements within the body of the DEIS are most appropriately placed in the appen­dices. Appendices must either be circulated with the draft EIS or be readily available for public review.

Index. An index to the DEIS should be provided to assist the reader in locating topics of interest.

Public Re-view and Comment. Upon completion, the DEIS is made available for pub­lic review and comment. Review of the DEIS should supplement the public outreach activities to date. A notice of availability of the DEIS should be published in the Federal Register and in newspapers of general circulation in the vicinity of the project site. Hard copies of the DEIS should be provided at libraries and other locations in the vicinity of the geographic area that would be potentially affected by the proposed action. Electronic copies of the DEIS and its supporting documentation should also be made available on the website of the sponsoring agency. Provisions should be made for major foreign lan­guage populations in the area, including the publication of notices in the language of major non-English speaking populations in the area, and the provision of translators at any public hearings.

The notice of availability of the DEIS should indicate the date by which public com­ments must be received and the dates, times, and locations of any public hearing(s) on the DEIS. Adequate notice should be provided to any public hearings to allow sufficient time for public examination and assessment of the DEIS. All substantive comments received on the DEIS during the public review period, including all written comments and oral com­ments received at any public hearing on the DEIS, should be documented and summarized. Responses must be prepared to all substantive comments. Responses to nonsubstantive comments and gratuitous remarks on the DEIS are not required.

Final EIS. Upon completion of the public comment period on the DEIS, an analysis is completed of the comments received, necessary revisions are made to the analyses and

conclusions in the DEIS, and a final EIS (FEIS) is prepared. The FEIS must document and include responses to all substantive comments received on the DEIS from public agencies and the public (40 CFR §1502.18). Responses to comments can be made in the form of changes to the text and analyses included in the DEIS, factual corrections, new alterna­tives considered or an explanation of why a comment does not require a response (40 CFR §1503.4). A copy or summary of substantive comments and the responses to them must be included in the FEIS [40 CFR §1503.4(a)]. The contents of an FEIS is provided in Table 1.6.

If not already identified in the DEIS, the FEIS should identify the preferred alternative to be recommended for implementation. The preferred alternative could be one of the rea­sonable alternatives considered in the DEIS or an alternative that is a composite or variant of the reasonable alternatives considered in the DEIS.

If the preferred alternative will involve the use of a resource protected under Section 4(f), a final Section 4(f) evaluation must be prepared and included as a separate section of the FEIS or as a separate document.

When completed, the FHWA will publish the FEIS and EPA will publish a notice of availability of the FEIS in the Federal Register. A minimum of 30 days must pass after publication of the FEIS before FHWA can make a final decision on the proposed action (40 CFR §1504).

Record of Decision. Preparation and publication of a record of decision (ROD) by FHWA is the final step in the EIS process. The ROD documents the decisions made by FHWA for the proposed action, including identification of the preferred alternative, and the measures identified to mitigate any identified adverse impacts of the preferred alternative, including the commitments and plans to enforce and monitor implementation of the mea­sures (40 CFR §1505.2). The ROD also discloses the bases for the agency’s decision, including the reasons for whether to proceed with the proposed action. The ROD must also discuss whether all practical means have been applied to avoid or minimize environmental harm have been adopted, and, if not, why they were not (40 CFR §1505.2). The ROD must be made publicly available by publication in the Federal Register or on the agency web­site, or both.

Environmental Reevaluation and Supplemental EIS. An environmental reevaluation (ER) of the FEIS is prepared when any of the following circumstances occur:

• An acceptable FEIS is not submitted to FHWA within 3 years from the date of circula­tion of the DEIS.

• No major steps have been taken to advance a project (e. g., allocation of a substantial por­tion of right-of-way or construction funding) within 3 years from the date of approval of the FEIS.

• When there have been lengthy periods of inactivity between major steps to advance the project.

The purpose of the reevaluation is to determine whether there has been a substantial change in the social, economic, and environmental effects of the proposed action. This could result from changes in the project itself or from changes in the context under which the project is to be undertaken.

A supplemental EIS should be prepared when there are changes that result in significant impacts not previously disclosed in the original document. An EIS may be supplemented or amended at any time and must be supplemented or amended when (1) changes to the pro­posed project would result in significant environmental impacts that were not disclosed in the EIS or (2) new information or circumstances relevant to environmental concerns and bearing on the proposed project or its impacts would either bring to light or result in sig­nificant environmental impacts not evaluated in the original document. The supplemental EIS need only address those subjects in the original document affected by the changes or new information.

NATIONAL ENVIRONMENTAL POLICY ACT OF 1969 (NEPA)

NEPA is the most important federal environmental legislation to be considered in the plan­ning and development of highway projects. NEPA was enacted by Congress in December 1969 and signed into law by President Nixon on January 1, 1970. It was the first compre­hensive environmental law in the United States and established the country’s national envi­ronmental policies. To implement these policies, NEPA requires federal agencies to assess the environmental effects of its discretionary actions prior to making decisions on such actions. Actions subject to NEPA include such activities as the financing or approving of projects or programs; the adoption of agency regulations and procedures; the permitting of private and public actions; and a broad range of other actions.

As indicated in Section 101 of NEPA, its purpose is “to declare a national policy which will encourage productive and enjoyable harmony between man and his envi­ronment; to promote efforts which will prevent or eliminate damage to the environment and biosphere and stimulate the health and welfare of man; to enrich the understanding of the ecological systems and natural resources important to the Nation; and to estab­lish a Council on Environmental Quality (CEQ)”, within the executive office of the president.

In addition to the agency specific regulations implementing NEPA, DOT and its con­stituent agencies have identified the process and methods to be used to assess environmen­tal impacts under NEPA in a number of orders, technical advisories, and memoranda. These include Order 5610.1C, Procedures for Considering Environmental Impacts (9/18/1979), which established procedures for consideration of environmental impacts in decision making on proposed DOT actions. A draft revision to this order has been consid­ered by DOT (Draft Order 5610.1D, 7/5/2000), but has not been finalized. Further guidance for preparing environmental documents under NEPA is provided in FHWA Technical Advisory T6640.8A, Guidance for Preparing and Processing Environmental and Section 4(f) Documents (10/30/1987), the Federal Aid Policy Guide (FAPG), and a number of FHWA Policy Memoranda (see Table 1.1).

FEDERAL REQUIREMENTS GOVERNING TRANSPORTATION PLANNING AND THE ENVIRONMENT

The following discussion is intended to provide an overview of the principal federal requirements affecting the development and maintenance of highways. These include federal laws, regulations, executive orders, agency advisories, policy memoranda, and guidance documents. Federal laws are enacted legislation that establish a set of rules or principles codified in the United States Code (USC). Federal regulations implement federal laws and are codified in the Code of Federal Regulations (CFR). DOT and Council on Environmental Quality (CEQ) regulations implementing NEPA are codified in 23 CFR Part 771 ( United States Department of Transportation Environmental Impact and Related Procedures), and 40 CFR Parts 1500-1508 (Council on Environmental Quality Regulations Implementing NEPA). Environmental regulations have been promulgated by each federal agency. These include regulations promulgated by DOT, the U. S. Environmental Protection Agency (EPA), the U. S. Department of the Interior (USDOI), the U. S. Army Corps of Engineers (USACOE), and the U. S. Coast Guard (USCG), and can be found in the CFRs of the specific agency having jurisdiction over the environmental issue of concern.

In addition to NEPA and the resource-specific legislation summarized in Art. 1.3 of this chapter, there are a number of DOT requirements that affect the planning and envi­ronmental review of highway projects. These include

• Section 4(f) of the Department of Transportation Act of 1966 (23 USC §303)

• The Intermodal Surface Transportation Act of 1991 (Public Law 102-240)

• The Transportation Equity Act for the 21st Century (Public Law 105-178)

• The Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (Public Law 109-59, “SAFETEA-LU”)

• The National Highway Designation Act of 1995 (Section 29 of USC Title 23)

Provided below are brief descriptions of each of these statutes.

Section 4(f) of the Department of Transportation Act of 1966 (23 USC §303, “Section 4(f)”)- Section 4(f) prohibits the administrator of the Federal Highway Administration (FHWA) from approving the use of land from a significant publicly owned park, recre­ation area, or wildlife and waterfowl refuge, or any significant historic site for transporta­tion purposes unless a determination is made that

• There is no feasible and prudent alternative to the use of land from the property.

• The action includes all possible planning to minimize harm to the property resulting from such use.

In addition, supporting information must demonstrate that there are unique problems or unusual factors involved in the use of alternatives that avoid these properties (“Avoidance Alternatives”) or that the cost, social, economic, and environmental impacts, or community disruption resulting from such alternatives reach extraordinary magnitudes.

Section 6009(a) of SAFETEA-LU made the first substantive revision to Section 4(f) since its enactment in 1966. This section of SAFETEA-LU attempts to simplify the Section 4(f) process for projects that have only de minimis impacts on resources protected by Section 4(f). Under the new provisions, once DOT determines that a transportation use of a Section 4(f) resource results in a de minimis impact, analysis of avoidance alternatives is waived and the Section 4(f) process is deemed complete. Guidance for determining de minimis impacts to Section 4(f) resources was issued by FHWA and DOT on December 13, 2005. Section 6009(c) of SAFETEA-LU requires DOT to conduct a study and issue a report on the implementation of these new Section 4(f) provisions. The initial study and report is to address the first 3 years of its implementation.

Intermodal Surface Transportation Efficiency Act of 1991 (Public Law 102-240, “ISTEA”). ISTEA was almost revolutionary in the breadth of how it looked at surface transportation, and the substantive role it played in regard to metropolitan planning orga­nizations, localities, and states. Covering the period 1992 through 1997, it restructured the Federal Aid Highway Program, and placed the emphasis on maintenance rather than whole­sale expansion of the highway network. In creating the Surface Transportation Program, ISTEA brought a new level of flexibility to the planning and implementation of highway and transit projects.

The Transportation Equity Act for the 21st Century (Public Law 105-178, “TEA-21”).

Enacted on June 9, 1998, TEA-21 authorized the Federal Surface Transportation Program for highways, highway safety, and transit for the 6-year period, 1998-2003, and increased the authorized funding level to $218 billion from $155 million under ISTEA. TEA-21 built upon ISTEA, allowing new initiatives, strengthening safety, and encour­aging flexibility in how to maximize performance of the transportation system.

The Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users of 2005 (Public Law 109-59, “SAFETEA-LU”). SAFETEA-LU built upon both ISTEA and TEA-21 included expanded programs in the areas of safety, equity, innovative financing, congestion relief, mobility and productivity, efficiency, and environmental stewardship. Of particular relevance to the consideration of environmental concerns affect­ing the development and implementation of highway projects, it included a number of changes aimed at streamlining the environmental review process. A new category of “participating agencies” was added to provide state, local, and tribal agencies with a formal role in the environmental review process, required that a schedule be defined for the partici­pation of agencies in the project review process, established a 180-day statute of limitations for lawsuits challenging federal agency approvals, allowed for broader state assumption of responsibilities for categorical exclusions from environmental review, exempted the Interstate System from Section 4(f) and National Historic Preservation Act requirements (although individual segments may receive protection), modified the requirements for determining whether the conformity of local and statewide transportation plans conform to the Federal Clean Air Act, and, as previously discussed, included tightly circumscribed exemptions from “Section 4(f)” requirements.

National Highway System Designation Act of 1995 (Public Law 104-59, Section 109 of Title 23, USC). Following the substantial completion of the Interstate System, the trans­portation focus for many states shifted to congestion management and system preservation

projects that involve existing facilities. Working with community stakeholders to preserve and enhance the human and natural environment is a significant component of these pro­jects. To address the challenges resulting from this new emphasis, many state transporta­tion agencies and professional organizations have implemented a “context-sensitive design” (CSD) approach to project development.

The National Highway System Designation Act (Section 109 of Title 23, USC) was enacted in November 1995. The act indicated that design for new construction, reconstruction, resurfacing, restoration, or rehabilitation of highways on the National Highway System (other than a highway also on the Interstate System) may take into account

• The constructed and natural environment of the area

• The environmental, scenic, aesthetic, historic, community, and preservation impacts of the activity

• Access for other modes of transportation

Five pilot states (Connecticut, Kentucky, Maryland, Minnesota, and Utah) were selected to implement the CSD approach to highway design. Principles for CSD can be found on the FHWA website at www. fhwa. got. gov/csd/principles.

ENVIRONMENTAL ISSUES AFFECTING HIGHWAY PROJECTS

Highway projects have the potential to result in significant social, environmental, and eco­nomic effects and, as a consequence, are the subject of a broad range of environmental reg­ulation. Potential impacts include effects on

• Community cohesion

• Land use

• Minority and disadvantaged populations

• Surface and groundwaters

• Wetlands

• Coastal zone resources

• Navigable waters

• Wild, scenic, and recreational rivers

• Flood plains

• Water quality

• Important ecological resources, including wetlands and threatened and endangered species

• Significant historic and archaeological resources

• Important visual resources

• Public parklands

• Utilities

• Prime agricultural lands

• Air quality

• Noise

• Energy

• Exposure to contaminated and hazardous materials

• Public health

Recent court rulings also suggest the need to consider potential effects on global climate change and related ecological impacts.

The impacts of highway projects may be both temporary (short-term effects that occur during construction of a facility) and permanent (long-term effects resulting from the operation of a facility). Both short – and long-term impacts can be direct, indirect, or cumulative.

• Direct impacts are effects directly caused by an action that occur at the same time and place and result from the direct use of land or resources.

• Indirect impacts are effects indirectly caused by an action and are later in time or farther removed in distance from the location of a facility, but which are still reasonably fore­seeable, including growth inducing effects and other effects related to induced changes in the pattern of land use, population density, or growth rate.

• Cumulative impacts are impacts which result from the incremental impact of an action when added to other past, present, and reasonably foreseeable future actions regardless

of what agency or person undertakes such other actions. Cumulative impacts can result from individually minor but collectively significant actions taking place over a period of time.

All of these effects must be considered in evaluating the environmental impacts of high­way projects.

Environmental concerns play a major role in the planning, design, construction, reha­bilitation, and maintenance of highways. This chapter provides an overview of the major environmental concerns affecting highway projects and includes a summary of the federal environmental statutes, regulations, policies, and guidance material that must be addressed in their development.

Included is a detailed discussion of the requirements of the National Environmental Policy Act of 1969 (NEPA), 42 USC §4321 et seq., the key federal environmental statute affecting the development of highway projects. Provided is a thorough descrip­tion of the process and substance required to prepare environmental documents under NEPA, including environmental assessments (EA) and environmental impact statements (EIS).

This chapter also includes a summary of the U. S. Department of Transportation (DOT) requirements governing the planning and development of highway projects included in the Safe, Accountable, Flexible, Efficient, Transportation Equity Act—A Legacy for Users (Public Law 109-59, “SAFETEA-LU”), and Section 4(f) of the Department of Transportation Act of 1966 (Title 49 USC §1653(f), “Section 4(f)”). Also provided is an overview of the major federal resource-specific environmental legislation and regulations not under the jurisdiction of DOT that highway planners and engineers must address during project development.

The chapter concludes with a thorough discussion of alternative means to remove lead – based paint from steel bridge structure, and the potential use of waste material in the con­struction and maintenance of highways, including the recycling of hazardous wastes within highway projects.
