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.

The myth of the Flood, a reflection of the ancestral threat of floods and inundations?

The Euphrates River, although less capricious than the great rivers of China, is subject to major floods and changes in course. The Flood is a common myth in all of Mesopotamia, existing in several versions. The oldest written version, written in Sumerian and discovered at Nippur, is unfortunately in very poor condition.[12] The most well-known version, the one that very likely inspired the biblical account in Genesis, is part of The Epic of Gilgamesh, a Babylonian account written in the first half of the IInd millennium BC in which the description of the event is situated in the Sumerian city of Shuruppak. Here is an extract:

“That stated time had arrived. In the morning he let loaves of bread shower down, and in the evening a rain of wheat. I watched the appearance of the weather—the weather was frightful to behold! I went into the boat and sealed the entry….

Just as dawn began to glow there arose from the horizon a black cloud. Adad rumbled inside of it, before him went Shullat and Hanish, heralds going over mountain and land. Erragal pulled out the mooring poles, forth went Ninurta and made the dikes overflow. The Anunnaki lifted up the torches, setting the land ablaze with their flare. Stunned shock over Adad’s deeds overtook the heavens, and turned to blackness all that had been light. The… land shattered like

a… pot. All day long the South Wind blew blowing fast, submerging the mountain in water,

overwhelming the people like an attack….

When the seventh day arrived, the storm was pounding, the flood was a war—struggling with itself like a woman writhing (in labor). The sea calmed, fell still, the whirlwind (and) flood stopped up.

I looked around all day long—quiet had set in and all the human beings had turned to clay! The terrain was as flat as a roof.”1J

Initially attracted by the desire to find traces of the great events of the Bible in the soil of Mesopotamia, archaeologists have searched for the ruins of the Sumerian villages in the signatures of the geological strata. Their studies have revealed significant and long-duration flood deposits, but only in some cities, and from different eras: At Ur from between 4500 and 4000 BC and then another episode dating from 2800 to 2600 BC; at Kish from three periods between 2800 and 2600 BC; and at Shuruppak, actually about 2900 BC.[13] [14] This city, which had been quite populous before, never again attained such status. No trace was found in the very ancient city of Eridu, despite its proximity to Ur (see Figure 1.3 or Figure 2.1 of Chapter 2 for the geography of these cities.)

Getting Acquainted with Tools and the Parts of a House

The craft of carpentry has a long and honorable heritage. Ages before we began recording our history, our ancestors were shaping and joining materials to create various types of shelters. Today, we are the fortunate inheritors of centuries of accumulated knowledge, experience, skills, and tools. Although carpentry continues to be transformed by technology (from computer-aided design programs to cordless tools and pneumatic nailers), many basic tools and techniques remain unchanged.

It still takes a human hand wrapped around a hammer handle to build a decent place to live. Like basic carpentry tools, many parts of the house have stayed the same over the years. Technology has improved some of the parts, as well as created new ones. But the house is still the same basic structure it always was. Before you start building a house, it’s essential to learn the com­mon language spoken on construction sites and in home centers, lumberyards, and building-supply stores.

Tool-Buying Tips

When I started working as a carpenter in the late 1940s, almost every task was done with hand tools. I remember spending hours cutting a pile of 2 x4s to length with a crosscut saw. Floors were sheathed with 1x6s, both ends of which had to be cut at 45-degree angles. Cutting all the pieces of a house by hand was a big job, to say the least. In 1950, when I bought my first circular saw, my world as a carpenter changed forever.

BASICSBut what began as a boon (the proliferation of new and better tools) has
over the years also become downright bewildering. These days, the number of

BASICS

tools on the market can make buying tools a difficult task. Each time I walk into a tool center or receive a tool catalog in the mail, I am amazed by the dizzying array of carpentry tools offered for sale. When there are 50 differ­ent models, even buying something as basic as a hammer can be frustrating.

Try before you buy

So what do you look for when buying a tool? Well, it helps to remember that tools are not like stretch socks, where one size fits all. A circular saw, for example, may have the right combina­tion of power and weight but still feel out of balance or awkward when you hold it. A tool that’s not comfortable is like a shoe that is one size too small. It’s never a bargain, regardless of price. A tool that feels good in your hands will most likely be easy and safe to use. So, whenever possible, try before you buy. Visit home centers
and tool dealers that have good selections of tools. Grip the tool to test its balance and feel. If you have small hands, rule out tools that aren’t easy to hold comfortably. Try the controls and adjustments, too. Use this hands-on information to make your selections.

Get advice from the pros

Talk to carpenters, who use tools daily, and ask them for their preferences. Research magazines, such as Fine Homebuilding and the Journal of Light Construction, which evaluate tools. And always buy the best quality you can afford.

Most of us know the experience of wishing we had bought quality rather than a piece of junk. Professional tools cost more initially, but they are more durable, more powerful, and easier and safer to use. Ironically, they make it easier to be a beginner.

Buy tools as you need them

If you’re intending to work professionally as a carpenter, you’ll eventually acquire quite a large collection of tools. If, however, you’re only plan­ning to build one house or work with Habitat as a weekend volunteer, a small kit of essential tools should stand you in good stead. In addi­tion to the basics described on the following pages, you can acquire more specialized tools as you need them, which is the best way to do it anyway. Otherwise, you may wind up with un­necessary tools that clutter your tool belt, your storage bucket, and your life. You can also rent specialized tools if you plan to use them just a few times.

STEP 4 SECURE THE BUILDING PERMITS

It’s not uncommon for builders or owner – builders to view the local building department as enemy turf. Let me suggest that your building experience will be immeasurably more positive, productive, and efficient if you view the build­ing department as a resource and think of the building inspector as someone who can help you. Certainly there are exceptions, as there are in any field, but, by and large, building depart­ments and building inspectors exist to protect prospective homeowners from unscrupulous or incompetent builders and owner-builders from themselves. The building inspector knows the building codes, which have been developed over the years to ensure that safe, durable houses are built. Your building inspector has the same

goals that you do. He or she wants a house that doesn’t leak, isn’t a fire hazard, complies with zoning requirements, and can stand up to every­day use and all but the most severe natural disas­ters. Building inspectors really are on your side.

Taking the plans to a building department to request permits need not be a big affair. I have often submitted basic plans on 11-in. by 14-in. sheets of paper. Plans do need to be drawn to scale, and the most common scale is ‘/4 in. =

1 ft.; this means that 1 in. on a plan equals 4 ft. in the actual house. Using graph paper can help with preliminary designing, but an inexpensive computer-aided design (CAD) program makes professional-looking plans that are simple to draw and easy to change. For a simple house, most building departments need the basic types of drawings shown on pp. 14, 16, and 17:

• Plot or site plan to give an overall view from above, showing the shape and dimensions of the property and the size and location of the building.

• Foundation plan to show the location and size of the concrete footings, walls, and piers that will support the floor frame.

• Floor plan to provide a bird’s-eye view of the size and arrangement of living spaces. The floor plan shows the location and size of doors and windows and often the location of electrical, plumbing, and heating system components (see the symbols explained in the sidebar at right). Even the location, spac­ing, and direction of the roof trusses can be found here.

• Wall sections to show the “guts” of the floors, walls, or ceilings. Think of a wall section drawing as an apple that’s been sliced in half to reveal its core (see the drawing on p. 16). Both section and detail plans (see p. 17) are sometimes drawn at a larger scale to better identify the details that wouldn’t show up as clearly in a smaller scale.

Подпись: READING FLOOR PLANS Building a house requires that you learn more than one new lan-guage. Besides the terminology of building (plates, braces, lined walls, plumb, toenail, and the like), there's also the visual vo-cabulary of lines, symbols, and notations found on building plans. Fortunately, most of these symbols are fairly easy to understand (see the illustration below). It's important to become familiar with building plans so that you can begin to visualize, from a two-dimensional representation, what the house will look like with the walls framed and the fixtures and appliances in place. It's far easier (and less expensive) to make a change at the planning stage than after the walls and rough plumbing are in place.

• Detail plans to provide close-up views of small sections of the house. These are use­ful for providing clarification or additional detail that isn’t shown in the other drawings.

If you can draw it, you can build it

If you’re drawing your own plans, the process— though slow and often frustrating—will give you a clearer understanding of your house than many builders ever have. It can save you from making costly mistakes and will likely contrib­ute to building a better house.

A good way to test your ability to visualize a house design based on plans is to visit some building sites where you can examine both the plans and the actual construction details as the house goes up. If you’ve bought stock plans, they may seem bewildering initially; as you work with them, they’ll become much easier to read and understand. The ability to both draw and read plans gets easier with experience.

STEP 5 GET ORGANIZED TO BUILD

Building a house is a process that consists of a seemingly endless number of steps. Knowing which step follows which—for example, when to call the electrical company to install a tempo­rary power pole, when to call the plumber to install drains and vents in the joist system—is key to organizing tasks and materials so that work isn’t held up. This knowledge comes primarily from experience, but for the first­time builder I’ve listed most of the steps in the process (see pp. 18—23).

When my brothers and I were building houses, we spent many hours planning and organizing so that we always knew what to do next, who would do it, and when and how it would be done. Organizing time and materials is an essential skill for any builder, whether that builder is working with professionals, friends, family, or Habitat volunteers. Staying organized and on top of the situation is
especially important when working with volun­teers and unskilled helpers. Careful planning, good organization, and effective communica­tion will ensure that less-experienced workers are able to contribute meaningfully and feel good about the work they are doing.

Display patience, understanding, and openness

People of all ages and abilities come to Habitat job sites wanting to work. Try to give them work that they can do successfully, so that more than just a house is built. Sometimes it’s easy to get along with your coworkers; at other times, it’s quite challenging. You’ll find this to be true on a Habitat project, on your own construction site, and in every situation in life. We all know what it’s like to work with people who are arrogant, have an attitude, or are unwilling to listen and learn. We also know what’s it’s like to work with people who treat us as equals, listen to us, show patience when we are trying to learn a new skill, and praise our efforts even when we fall short of expecta­tions. Try to be the latter, and have patience with the former.

"111 for Humanity

A guide for the first-time builder

The checklist on the following pages contains most of the major steps involved in building a small house. Naturally, there will always be un­foreseen or site-specific steps, but this list should serve as a fairly thorough guide to building a house, from raw idea to move-in day.

Getting started

• Look for land and determine whether you can build on it.

• Acquire a piece of land.

• Survey your land to confirm the boundaries.

• Buy or draw up plans or acquire plans through Habitat (see Resources on p. 279).

• Obtain permits from the building depart­ment and other departments, if necessary.

Подпись: Preparing the site. STEP 4 SECURE THE BUILDING PERMITSSHARING A VISION

It is important to have a decent place to live. Most of us don’t want to live in a mansion. We only want a clean, safe place where we can live and raise our children. A decent house uplifts our spirits and provides dignity and hope for the future.

It is hard for many people to realize what it’s like to live in a moldy, leaky house with rat holes in the wall and plumbing that’s inadequate or nonexistent. Yet that is the condition of millions of people living around the world today. Poor housing is not just somewhere else. Every city in this country has its share.

Habitat for Humanity has a goal of eliminating poor hous­ing by working with families who need a hand up. There is no magic wand to wave that will produce a new home. Decent housing is built because people like you and me roll up our sleeves, pick up our hammers, and start building. What we may not be able to do alone can be accomplished when we work together. Lots of sweat, a little skill, and a shared vision get the job done.

During this process of working together, we build much more than houses. We meet all kinds of interesting people and develop close friendships as we work side by side, take breaks together, and share stories.

Pavements and Earthworks

1.4.1 Definitions

In today’s world almost all traffic runs on an improved surface and not on the nat­ural soil profile… and most users give such improved surfaces little thought. This improved surface is known as a pavement and may be a simple layer of imported aggregate or the structure that comprises a modern expressway. In fact, all but the very simplest pavements comprise a series of carefully designed layers of imported, selected, construction materials placed on the “subgrade” (Fig. 1.4). The subgrade

Pavements and Earthworks

Fig. 1.4 Indicative highway cross section

may either be the natural soil profile encountered at the site (e. g. when the pave­ment construction is built at the same level as the surrounding ground, or when it is built in a cutting) or it may be a “fill” material that has been imported to create an embankment.

This fill is often subgrade soil from some other location, but might also be a by­product or waste material. Even in a cutting, some material may have been imported to form the subgrade as it can aid drainage – and thus improve the performance of the pavement. Material specifically designed to provide an improved subgrade is known as “capping”. It may either be imported or may be achieved by some improvement technique applied to the natural subgrade in-situ (Fig. 1.4).

It is not only the pavement that needs draining; drainage of embankments and cuttings is also important to give soil-based slope stability and longevity of performance.

Finally, what about “moisture” and “water”? Both terms are used, more or less synonymously in this book. In general the direct term “water” is preferred to the more indirect term “moisture”, although “moisture” is often used to describe water in the unsaturated parts of the sub-surface.

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.

FLOORS AND STAIRS

Squeaky floors may take 2 minutes to repair or 2 days, when the cause is elusive. If you can live with some squeaks, they’re rarely a sign of any­thing serious.

Excessively springy floors suggest subflooring or underlayment that’s not strong enough to span the joists. Additional layers of subflooring or flooring should firm things up.

Deteriorating flooring near an exterior door – sill suggests that rain or snow has soaked the sill and subflooring. You’ll need to replace damaged materials and install an all-weather doorsill.

Widespread cracking in tile floors may result from insufficient adhesive between tile and sub­flooring or an underlayment that’s too thin and thus not rigid enough. Repairing it may mean tearing out the tile and perhaps the underlay – ment before replacing both.

Cracked stair treads may be worn, undersize, or inadequately supported by the carriages

underneath. If the problem is widespread, remove the treads and examine the substructure.

Stairs sloping badly to one side, with cracked walls along the stair suggest a stair carriage that is pulling loose from wall mountings or other framing members. If the underside of the stairs is not accessible, repairing the problem can be complex and costly.

Handrails and newel posts that wobble more than h in. should be resecured. If balusters are missing, it can be costly to have replacements hand-turned to match. As a cost-saving alterna­tive, you might be able to find replacements at a salvage yard.

KITCHENS AND BATHROOMS

If there are stained, springy floors around the base of a toilet, the subfloor and the joists below may be water damaged. The cause of the leak may be simple—just a worn-out wax ring gasket under the toilet. But if damage is significant, you may need to pull up flooring and replace it.

Damaged linoleum or vinyl around cabinets, shower stalls, or tubs often foretells water dam­age below. If there’s an unfinished basement beneath those fixtures, inspect there for damage. Otherwise, look for water damage in finished ceilings below.

If tiled tub enclosures are in poor repair, test the firmness of the substrate behind by pushing with the heel of your hand. If the walls flex, the tile may be installed over ordinary drywall, which deteriorates if it absorbs water. One remedy is tearing out the tile and drywall and installing a cement-based backer board before retiling.

Check tub-wall joints closely. They must be well caulked to forestall leaks.

Подпись: TIPПодпись: To test whether a toilet is securely mounted, bend over the toilet, grab the edges of the bowl (while wearing work gloves) and try to rock it from side to side. If the bowl moves slightly, tighten the toilet nuts at the base—but don't overtighten or you'll crack the porcelain—and then try again. If it still rocks, the subfloor may be spongy and need replacing. 1111 Use your pocketknife to prod for damage under lavatory and kitchen sink cabinets. Rusted – out drainpipes or leaking supply-pipe connec­tions are easily replaced, but extensive water damage can be costly to remedy.

PIPE LIFE AND Water QUALITY

If supply pipes are galvanized steel, their useful life is about 25 years. Copper supply pipes installed before 1990 may contain lead in solder joints, which can leach into drinking water. So before making an offer, get the water tested for lead and other toxins. If the pipes appear to be otherwise in good condition, an in-line filtration system with replaceable filters may be a cost-effective solution to this problem.

If bathrooms or kitchens smell musty or are mildewed, especially at the top of walls, there’s inadequate ventilation. Scrubbing walls and adding vent fans will probably cure the problem, unless the drywall is crumbling (see Chapter 14 for repair information).

IN THE BASEMENT

Safety note: Stay out of basements or crawl spaces if there’s standing water, wet soil, or sub­standard electrical wiring! Metal pipes or duct­work could become energized by a short circuit.

Dampness can be mitigated by gutters and downspouts, as well as a ground surface that slopes away from the house. Musty smells and mild mold can usually be reduced by improving ventilation. Beyond that, fixes get more complex and more expensive.

Wetness is often caused by surface water and may respond to the remedies mentioned in the preceding paragraph. Stronger remedies include sump pumps, perimeter drains, and engineered solutions. For example, water seeping through an uphill foundation wall may need to be intercepted and rerouted by drainpipes or swale drains far­ther uphill. Solutions can become expensive.

The River: menace or blessing?

All of the great early civilizations were born in alluvial valleys – notably the Tigris – Euphrates delta, then the valleys of the Nile, the Indus, and the Yellow River (Figure 1.2). The soil in those valleys is fertile, but must be irrigated and drained, and this requires the establishment of coordinated water management. But there is another con­sideration: populations near the river are exposed to the deadly threat of flooding. Flood protection is therefore another fundamental need, demanding societal organization of significant manpower, and attracting population agglomeration to sites that can readily be protected. All of this implies a certain collective and hierarchical organization.

The River: menace or blessing?

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

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.

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.

Organisation of Book

The book covers both theory and practice and addresses both sub-surface drainage and water quality issues. Chapter 2 deals with basic flow and suction theory and Chapter 4 with heat transfer, which is implicated in driving water movement by phase change mechanisms (freezing, thawing, evaporation). Chapter 6 establishes a basis for discussing environmental aspects, introducing contaminant transport pro­cesses. Chapters 3 and 7 give an overview of the available techniques to monitor water flow, suction pressures and contaminants in water. After this introductory and descriptive section of the book, Chapters 8-11 aim to explain interaction between water in soil and aggregate and the mechanical response of such materials. This explanation covers theory, field behaviour, laboratory testing and theoretical and numerical modelling. The book ends with two chapters that aim to guide readers to improve the environmental condition, to reduce water pressure and to reduce the volume of water in the pavement and adjacent soils. Aspects only of relevance to environmental matters are covered in Chapter 12 while the much longer Chapter 13 describes the many techniques that can be used to manage water in the pavement and near-pavement soils. Often such management has benefits to both the mechanical and environmental performance of the pavement structure and earthworks.
