Document:
The Council on Environmental Quality (CEQ) regulations implementing the National Environmental Policy Act (NEPA) were issued on November 29, 1978. These regulations became effective for, and binding upon, most federal agencies on July 30, 1979, and for all remaining federal agencies on November 30, 1979.
As part of the Council's NEPA oversight responsibilities it solicited through an August 14, 1981, notice in the Federal Register public and agency comments regarding a series of questions that were developed to provide information on the manner in which federal agencies were implementing the CEQ regulations. On July 12, 1982, the Council announced the availability of a document summarizing the comments received from the public and other agencies and also identifying issue areas which the Council intended to review. On August 12, 1982, the Council held a public meeting to address those issues and hear any other comments which the public or other interested agencies might have about the NEPA process. The issues addressed in this guidance were identified during this process.
There are many ways in which agencies can meet their responsibilities under NEPA and the 1978 regulations. The purpose of this document is to provide the Council's guidance on various ways to carry out activities under the regulations.
The Council on Environmental Quality (CEQ) regulations direct federal agencies which have made a decision to prepare an environmental impact statement to engage in a public scoping process. Public hearings or meetings, although often held, are not required; instead the manner in which public input will be sought is left to the discretion of the agency.
The purpose of this process is to determine the scope of the EIS so that preparation of the document can be effectively managed. Scoping is intended to ensure that problems are identified early and properly studied, that issues of little significance do not consume time and effort, that the draft EIS is thorough and balanced, and that delays occasioned by an inadequate draft EIS are avoided. The scoping process should identify the public and agency concerns; clearly define the environmental issues and alternatives to be examined in the EIS including the elimination of nonsignificant issues; identify related issues which originate from separate legislation, regulation, or Executive Order (e.g. historic preservation or endangered species concerns); and identify state and local agency requirements which must be addressed. An effective scoping process can help reduce unnecessary paperwork and time delays in preparing and processing the EIS by clearly identifying all relevant procedural requirements.
In April 1981, the Council issued a "Memorandum for General Counsels, NEPA Liaisons and Participants in Scoping" on the subject of Scoping Guidance. The purpose of this guidance was to give agencies suggestions as to how to more effectively carry out the CEQ scoping requirement. The availability of this document was announced in the Federal Register at 46 FR 25461. It is still available upon request from the CEQ General Counsel's office.
The concept of lead agency (§1508.16) and cooperating agency (§1508.5) can be used effectively to help manage the scoping process and prepare the environmental impact statement. The lead agency should identify the potential cooperating agencies. It is incumbent upon the lead agency to identify any agency which may ultimately be involved in the proposed action, including any subsequent permitting [48 FR 34264]a actions. Once cooperating agencies have been identified they have specific responsibility under the NEPA regulations (40 CFR 1501.6). Among other things cooperating agencies have responsibilities to participate in the scoping process and to help identify issues which are germane to any subsequent action it must take on the proposed action. The ultimate goal of this combined agency effort is to produce an EIS which in addition to fulfilling the basic intent of NEPA, also encompasses to the maximum extent possible all the environmental and public involvement requirements of state and federal laws, Executive Orders, and administrative policies of the involved agencies. Examples of these requirements include the Fish and Wildlife Coordination Act, the Clean Air Act, the Endangered Species Act, the National Historic Preservation Act, the Wild and Scenic Rivers Act, the Farmland Protection Policy Act, Executive Order 11990 (Protection of Wetlands), and Executive Order 11998 (Floodplain Management).
It is emphasized that cooperating agencies have the responsibility and obligation under the CEQ regulations to participate in the scoping process. Early involvement leads to early identification of significant issues, better decisionmaking, and avoidance of possible legal challenges. Agencies with "jurisdiction by law" must accept designation as a cooperating agency if requested (40 CFR 1501.6).
One of the functions of scoping is to identify the public involvement/public hearing procedures of all appropriate state and federal agencies that will ultimately act upon the proposed action. To the maximum extent possible, such procedures should be integrated into the EIS process so that joint public meetings and hearings can be conducted. Conducting joint meetings and hearings eliminates duplication and should significantly reduce the time and cost of processing an EIS and any subsequent approvals. The end result will be a more informed public cognizant of all facets of the proposed action.
It is important that the lead agency establish a process to properly manage scoping. In appropriate situations the lead agency should consider designating a project coordinator and forming an interagency project review team. The project coordinator would be the key person in monitoring time schedules and responding to any problems which may arise in both scoping and preparing the EIS. The project review team would be established early in scoping and maintained throughout the process of preparing the EIS. This review team would include state and local agency representatives. The review team would meet periodically to ensure that the EIS is complete, concise, and prepared in a timely manner.
A project review team has been used effectively on many projects. Some of the more important functions this review team can serve include: (1) A source of information, (2) a coordination mechanism, and (3) a professional review group. As an information source, the review team can identify all federal, state, and local environmental requirements, agency public meeting and hearing procedures, concerned citizen groups, data needs and sources of existing information, and the significant issues and reasonable alternatives for detailed analysis, excluding the non-significant issues. As a coordination mechanism, the team can ensure the rapid distribution of appropriate information or environmental studies, and can reduce the time required for formal consultation on a number of issues (e.g., endangered species or historic preservation). As a professional review group the team can assist in establishing and monitoring a tight time schedule for preparing the EIS by identifying critical points in the process, discussing and recommending solutions to the lead agency as problems arise, advising whether a requested analysis or information item is relevant to the issues under consideration, and providing timely and substantive review comments on any preliminary reports or analyses that may be prepared during the process. The presence of professionals from all scientific disciplines which have a significant role in the proposed action could greatly enhance the value of the team.
The Council recognizes that there may be some problems with the review team concept such as limited agency travel funds and the amount of work necessary to coordinate and prepare for the periodic team meetings. However, the potential benefits of the team concept are significant and the Council encourages agencies to consider utilizing interdisciplinary project review teams to aid in EIS preparation. A regularly scheduled meeting time and location should reduce coordination problems. In some instances, meetings can be arranged so that many projects are discussed at each session. The benefits of the concept are obvious: timely and effective preparation of the EIS, early identification and resolution of any problems which may arise, and elimination, or at least reduction of, the need for additional environmental studies subsequent to the approval of the EIS.
Since the key purpose of scoping is to identify the issues and alternatives for consideration, the scoping process should "end" once the issues and alternatives to be addressed in the EIS have been clearly identified. Normally this would occur during the final stages of preparing the draft EIS and before it is officially circulated for public and agency review.
The Council encourages the lead agency to notify the public of the results of the scoping process to ensure that all issues have been identified. The lead agency should document the results of the scoping process in its administrative record.
The NEPA regulations place a new and significant responsibility on agencies and the public alike during the scoping process to identify all significant issues and reasonable alternatives to be addressed in the EIS. Most significantly, the Council has found that scoping is an extremely valuable aid to better decisionmaking. Thorough scoping may also have the effect of reducing the frequency with which proposed actions are challenged in court on the basis of an inadequate EIS. Through the techniques identified in this guidance, the lead agency will be able to document that an open public involvement process was conducted, that all reasonable alternatives were identified, that significant issues were identified and non-significant issues eliminated, and that the environmental public involvement requirements of all agencies were met, to the extent possible, in a single "one-stop" process.
Section 1507 of the CEQ regulations directs federal agencies when establishing implementing procedures to identify those actions which experience has indicated will not have a significant environmental effect and to categorically exclude them from NEPA review. In our August 1981 request for public comments, we asked the question "Have categorical exclusions been adequately identified and defined?".
The responses the Council received indicated that there was considerable belief that categorical exclusions were not adequately identified and defined. A number of commentators indicated that agencies had not identified all categories of actions that meet the categorical exclusion definition (§1508.4) or that agencies were overly restrictive in their interpretations of categorical exclusions. Concerns were expressed that agencies were requiring [48 FR 34265] too much documentation for projects that were not major federal actions with significant effects and also that agency procedures to add categories of actions to their existing lists of categorical exclusions were too cumbersome.
The National Environmental Policy Act and the CEQ regulations are concerned primarily with those "major federal actions signficantly affecting the quality of the human environment" (42 U.S.C. 4332). Accordingly, agency procedures, resources, and efforts should focus on determining whether the proposed federal action is a major federal action significantly affecting the quality of the human environment. If the answer to this question is yes, an environmental impact statement must be prepared. If there is insufficient information to answer the question, an environmental assessment is needed to assist the agency in determining if the environmental impacts are significant and require an EIS. If the assessment shows that the impacts are not significant, the agency must prepare a finding of no significant impact. Further stages of this federal action may be excluded from requirements to prepare NEPA documents.
The CEQ regulations were issued in 1978 and most agency implementing regulations and procedures were issued shortly thereafter. In recognition of the experience with the NEPA process that agencies have had since the CEQ regulations were issued, the Council believes that it is appropriate for agencies to examine their procedures to insure that the NEPA process utilizes this additional knowledge and experience. Accordingly, the Council strongly encourages agencies to re-examine their environmental procedures and specifically those portions of the procedures where "categorical exclusions" are discussed to determine if revisions are appropriate. The specific issues which the Council is concerned about are (1) the use of detailed lists of specific activities for categorical exclusions, (2) the excessive use of environmental assessments/findings of no significant impact and (3) excessive documentation.
The Council has noted some agencies have developed lists of specific activities which qualify as categorical exclusions. The Council believes that if this approach is applied narrowly it will not provide the agency with sufficient flexibility to make decisions on a project-by-project basis with full consideration to the issues and impacts that are unique to a specific project. The Council encourages the agencies to consider broadly defined criteria which characterize types of actions that, based on the agency's experience, do not cause significant environmental effects. If this technique is adopted, it would be helpful for the agency to offer several examples of activities frequently performed by that agency's personnel which would normally fall in these categories. Agencies also need to consider whether the cumulative effects of several small actions would cause sufficient environmental impact to take the actions out of the categorically excluded class.
The Council also encourages agencies to examine the manner in which they use the environmental assessment process in relation to their process for identifying projects that meet the categorical exclusion definition. A report(1 ) to the Council indicated that some agencies have a very high ratio of findings of no significant impact to environmental assessments each year while producing only a handful of EIS's. Agencies should examine their decisionmaking process to ascertain if some of these actions do not, in fact, fall within the categorical exclusion definition, or, conversely, if they deserve full EIS treatment.
As previously noted, the Council received a number of comments that agencies require an excessive amount of environmental documentation for projects that meet the categorical exclusion definition. The Council believes that sufficient information will usually be available during the course of normal project development to determine the need for an EIS and further that the agency's administrative record will clearly document the basis for its decision. Accordingly, the Council strongly discourages procedures that would require the preparation of additional paperwork to document that an activity has been categorically excluded.
Categorical exclusions promulgated by an agency should be reviewed by the Council at the draft stage. After reviewing comments received during the review period and prior to publication in final form, the Council will determine whether the categorical exclusions are consistent with the NEPA regulations.
During the recent effort undertaken by the Council to review the current NEPA regulations, several participants indicated federal agencies were not utilizing the adoption procedures as authorized by the CEQ regulations. The concept of adoption was incorporated into the Council's NEPA Regulations (40 CFR 1506.3) to reduce duplicative EISs prepared by Federal agencies. The experiences gained during the 1970's revealed situations in which two or more agencies had an action relating to the same project; however, the timing of the actions was different. In the early years of NEPA implementation, agencies independently approached their activities and decisions. This procedure lent itself to two or even three EISs on the same project. In response to this situation the CEQ regulations authorized agencies, in certain instances, to adopt environmental impact statements prepared by other agencies.
In general terms, the regulations recognize three possible situations in which adoption is appropriate. One is where the federal agency participated in the process as a cooperating agency. (40 CFR 1506.3(c)). In this case, the cooperating agency may adopt a final EIS and simply issue its record of decision.(2) However, the cooperating agency must independently review the EIS and determine that its own NEPA procedures have been satisfied.
A second case concerns the federal agency which was not a cooperating agency, but is, nevertheless, undertaking an activity which was the subject of an EIS. (40 CFR 1506.3(b)). This situation would arise because an agency did not anticipate that it would be involved in a project which was the subject of another agency's EIS. In this instance where the proposed action is substantially the same as that action described in the EIS, the agency may adopt the EIS and recirculate (file with EPA and distribute to agencies and the public) it as a final EIS. However, the agency must independently review the EIS to determine that it is current and that its own NEPA procedures have been satisfied. When recirculating the final EIS the agency should provide information which identifies what federal action is involved.
The third situation is one in which the proposed action is not substantially the same as that covered by the EIS. In this case, any agency may adopt an EIS or a portion thereof by circulating the EIS as a draft or as a portion of the agency's draft and preparing a final EIS. (40 CFR 1506.3(a)). Repetitious analysis and time consuming data collection can be easily eliminated utilizing this procedure.
First, when an agency adopts such an analysis it must independently evaluate the information contained therein and take full responsibility for its scope and content.
Second, if the proposed action meets the criteria set out in 40 CFR 1501.4(e)(2), a Finding of No Significant Impact would be published for 30 days of public review before a final determination is made by the agency on whether to prepare an environmental impact statement.
Section 1506.5(c) of the NEPA regulations contains the basic rules for agencies which choose to have an environmental impact statement prepared by a contractor. That section requires the lead or cooperating agency to select the contractor, to furnish guidance and to participate in the preparation of the environmental impact statement. The regulation requires contractors who are employed to prepare an environmental impact statement to sign a disclosure statement stating that they have no financial or other interest in the outcome of the project. The responsible federal official must independently evaluate the statement prior to its approval and take responsibility for its scope and contents.
This provision does not apply when the lead agency is preparing the EIS based on information provided by a private applicant. In this situation, the private applicant can obtain its information from any source. Such sources could include a contractor hired by the private applicant to do environmental, engineering, or other studies necessary to provide sufficient information to the lead agency to prepare an EIS. The agency must independently evaluate the information and is responsible for its accuracy.
The purpose of the disclosure statement requirement is to avoid situations in which the contractor preparing the environmental impact statement has an interest in the outcome of the proposal. Avoidance of this situation should, in the Council's opinion, ensure a better and more defensible statement for the federal agencies. This requirement also serves to assure the public that the analysis in the environmental impact statement has been prepared free of subjective, self-serving research and analysis.
Some persons believe these restrictions are motivated by undue and unwarranted suspicion about the bias of contractors. The Council is aware that many contractors would conduct their studies in a professional and unbiased manner. However, the Council has the responsibility of overseeing the administration of the National Environmental Policy Act in a manner most consistent with the statute's directives and the public's expectations of sound government. The legal responsibilities for carrying out NEPA's objectives rest solely with federal agencies. Thus, if any delegation of work is to occur, it should be arranged to be performed in as objective a manner as possible.
Preparation of environmental impact statements by parties who would suffer financial losses if, for example, a "no action" alternative were selected, could easily lead to a public perception of bias. It is important to maintain the public's faith in the integrity of the EIS process, and avoidance of conflicts in the preparation of environmental impact statements is an important means of achieving this goal.
The Council has discovered that some agencies have been interpreting the conflicts provision in an overly burdensome manner. In some instances, multidisciplinary firms are being excluded from environmental impact statements preparation contracts because of links to a parent company which has design and/or construction capabilities. Some qualified contractors are not bidding on environmental impact statement contracts because of fears that their firm may be excluded from future design or construction contracts. Agencies have also applied the selection and disclosure provisions to project proponents who wish to have their own contractor for providing environmental information. The result of these misunderstandings has been reduced competition in bidding for EIS preparation contracts, unnecessary delays in selecting a contractor and preparing the EIS, and confusion and resentment about the requirement. The Council believes that a better understanding of the scope of §1506.5(c) by agencies, contractors and project proponents will eliminate these problems.
Section 1506.5(c) prohibits a person or entity entering into a contract with a federal agency to prepare an EIS when that party has at that time and during the life of the contract pecuniary or other interests in the outcomes of the proposal. Thus, a firm which has an agreement to prepare an EIS for a construction project cannot, at the same time, have an agreement to perform the construction, nor could it be the owner of the construction site. However, if there are no such separate interests or arrangements, and if the contract for EIS preparation does not contain any incentive clauses or guarantees of any future work on the project, it is doubtful that an inherent conflict of interest will exist. Further, §1506.5(c) does not prevent an applicant from submitting information to an agency. The lead federal agency should evaluate potential conflicts of interest prior to entering into any contract for the preparation of environmental documents.
Numerous comments have been received questioning an agency's obligation, under the National Environmental Policy Act, to evaluate alternatives to a proposed action developed by an applicant for a federal permit or license. This concern arises from a belief that projects conceived and developed by private parties should not be questioned or second-guessed by the government. There has been discussion of developing two standards to determining the range of alternatives to be evaluated: The "traditional" standard for projects which are initiated and developed by a Federal agency, and a second standard of evaluating only those alternatives presented by an applicant for a permit or license.
Neither NEPA nor the CEQ regulations make a distinction between actions initiated by a Federal agency and by applicants. Early NEPA case law, while emphasizing the need for a rigorous examination of alternatives, did [48 FR 34267] not specifically address this issue. In 1981, the Council addressed the question in its document, "Forty Most Asked Questions Concerning CEQ's National Environmental Policy Act Regulations".(5 ) The answer indicated that the emphasis in determining the scope of alternatives should be on what is "reasonable". The Council said that, "Reasonable alternatives include those that are practical or feasible from the technical and economic standpoint and using common sense rather than simply desirable from the standpoint of the applicant."
Since issuance of that guidance, the Council has continued to receive requests for further clarification of this question. Additional interest has been generated by a recent appellate court decision. Roosevelt Campobello International Park Commission v. E.P.A. (6) dealt with EPA's decision of whether to grant a permit under the National Pollutant Discharge Elimination System to a company proposing a refinery and deep-water terminal in Maine. The court discussed both the criteria used by EPA in its selecting of alternative sites to evaluate, and the substantive standard used to evaluate the sites. The court determined that EPA's choice of alternative sites was "focused by the primary objectives of the permit applicant . . ." and that EPA had limited its consideration of sites to only those sites which were considered feasible, given the applicant's stated goals. The court found that EPA's criteria for selection of alternative sites was sufficient to meet its NEPA responsibilities.
This decision is in keeping with the concept that an agency's responsibilities to examine alternative sites has always been "bounded by some notion of feasibility" to avoid NEPA from becoming "an exercise in frivolous boilerplate".(7 ) NEPA has never been interpreted to require examination of purely conjectural possibilities whose implementation is deemed remote and speculative. Rather, the agency's duty is to consider "alternatives as they exist and are likely to exist."(8 ) In the Roosevelt Campobello case, for example, EPA examined three alternative sites and two alternative modifications of the project at the preferred alternative site. Other factors to be developed during the scoping process -- comments received from the public, other government agencies and institutions, and development of the agency's own environmental data -- should certainly be incorporated into the decision of which alternatives to seriously evaluate in the EIS. There is, however, no need to disregard the applicant's purposes and needs and the common sense realities of a given situation in the development of alternatives.
Despite these intentions, the Council perceives that the concept of tiering has caused a certain amount of confusion and uncertainty among individuals involved in the NEPA process. This confusion is by no means universal; indeed, approximately half of those commenting in response to our question about tiering (10 ) indicated that tiering is effective and should be used more frequently. Approximately one-third of the commentators responded that they had no experience with tiering upon which to base their comments. The remaining commentators were critical of tiering. Some commentators believed that tiering added an additional layer of paperwork to the process and encouraged, rather than discouraged, duplication. Some commentators thought that the inclusion of tiering in the CEQ regulations added an extra legal requirement to the NEPA process. Other commentators said that an initial EIS could be prepared when issues were too broad to analyze properly for any meaningful consideration. Some commentators believed that the concept was simply not applicable to the types of projects with which they worked; others were concerned about the need to supplement a tiered EIS. Finally, some who responded to our inquiry questioned the courts' acceptance of tiered EISs.
The Council believes that misunderstanding of tiering and its place in the NEPA process is the cause of much of this criticism. Tiering, of course, is by no means the best way to handle all proposals which are subject to NEPA analysis and documentation. The regulations do not require tiering; rather, they authorize its use when an agency determines it is appropriate. It is an option for an agency to use when the nature of the proposal lends itself to tiered EIS(s).
Tiering does not add an additional legal requirement to the NEPA process. An environmental impact statement is required for proposals for legislation and other major Federal actions significantly affecting the quality of the human environment. In the context of NEPA, "major Federal actions" include adoption of official policy, formal plans, and programs as well as approval of specific projects, such as construction activities in a particular location or approval of permits to an outside applicant. Thus, where a Federal agency adopts a formal plan which will be executed throughout a particular region, and later proposes a specific activity to implement that plan in the same region, both actions need to be analyzed under NEPA to determine whether they are major actions which will significantly affect the environment. If the answer is yes in both cases, both actions will be subject to the EIS requirement, whether tiering is used or not. The agency then has one of two alternatives: Either preparation of two environmental impact statements, with the second repeating much of the analysis and information found in the first environmental impact statement, or tiering the two documents. If tiering is utilized, the site-specific EIS contains a summary of the issues discussed in the first statement and the agency will incorporate by reference discussions from the first statement. Thus, the second, or site-specific statement, would focus primarily on the issues relevant to the specific proposal, and would not duplicate material found in the first EIS. It is difficult to understand, given this scenario, how tiering can be criticized for adding an unnecessary layer to the NEPA process; rather, it is intended to streamline the existing process.
The Council agrees with commentators who stated that there are stages in the development of a proposal for a program, plan or policy when the issues are too broad to lend themselves to meaningful analysis in the framework of an EIS. The CEQ regulations specifically define a "proposal" as existing at, "that stage in the development of an action when an agency subject to [NEPA] has a goal and is actively preparing to make a decision on one or more alternative means of accomplishing the goal and the effects can be meaningfully evaluated." (11) Tiering is not intended to force an agency to prepare an EIS before this stage is reached; rather, it is a technique to be used once meaningful analysis can [48 FR 34268] be performed. An EIS is not required before that stage in the development of a proposal, whether tiering is used or not.
The Council also realizes that tiering is not well suited to all agency programs. Again, this is why tiering has been established as an option for the agency to use, as opposed to a requirement.
A supplemental EIS is required when an agency makes substantial changes in the proposed action relevant to environmental concerns, or when there are signifcant new circumstances or information relevant to environmental concerns bearing on the proposed action, and is optional when an agency otherwise determines to supplement an EIS.(12) The standard for supplementing an EIS is not changed by the use of tiering; there will no doubt be occasions when a supplement is needed, but the use of tiering should reduce the number of those occasions.
Finally, some commentators raised the question of courts' acceptability of tiering. This concern is understandable, given several cases which have reversed agency decisions in regard to a particular programmatic EIS. However, these decisions have never invalidated the concept of tiering, as stated in the CEQ regulations and discussed above. Indeed, the courts recognized the usefulness of the tiering approach in case law before the promulgation of the tiering regulation. Rather, the problems appear when an agency determines not to prepare a site-specific EIS based on the fact that a programmatic EIS was prepared. In this situation, the courts carefully examine the analysis contained in the programmatic EIS. A court may or may not find that the programmatic EIS contains appropriate analysis of impacts and alternatives to meet the adequacy test for the site-specific proposal. A recent decision by the Ninth Circuit Court of Appeals (13) invalidated an attempt by the Forest Service to make a determination regarding wilderness and non-wilderness designations on the basis of a programmatic EIS for this reason. However, it should be stressed that this and other decisions are not a repudiation of the tiering concept. In these instances, in fact, tiering has not been used; rather, the agencies have attempted to rely exclusively on programmatic or "first level" EISs which did not have site-specific information. No court has found that the tiering process as provided for in the CEQ regulations is an improper manner of implementing the NEPA process.
In summary, the Council believes that tiering can be a useful method of reducing paperwork and duplication when used carefully for appropriate types of plans, programs and policies which will later be translated into site-specific projects. Tiering should not be viewed as an additional substantive requirement, but rather a means of accomplishing the NEPA requirements in an efficient manner as possible.
Environmental Law Institute, NEPA In Action Environmental Offices in Nineteen Federal Agencies, A Report To the Council on Environmental Quality, October 1981.
Records of decision must be prepared by each agency responsible for making a decision, and cannot be adopted by another agency.
The Council also received requests for guidance on effective management of the third-party environmental impact statement approach. However, the Council determined that further study regarding the policies behind this technique is warranted, and plans to undertake that task in the future.
There is no bar against the agency considering candidates suggested by the applicant, although the Federal agency must retain its independence. If the applicant is seen as having a major role in the selection of the contractor, contractors may feel the need to please both the agency and the applicant. An applicant's suggestion, if any, to the agency regarding the choice of contractors should be one of many factors involved in the selection process.
