40 CFR 1501: NEPA and Agency Planning
40 CFR 1501.2: Apply NEPA early in the process
Agencies shall integrate the NEPA process with other planning at the earliest possible time to insure that planning and decisions reflect environmental values, to avoid delays later in the process, and to head off potential conflicts. Each agency shall:
(a) Comply with the mandate of section 102(2)(A) to “utilize a systematic, interdisciplinary approach which will insure the integrated use of the natural and social sciences and the environmental design arts in planning and in decisionmaking which may have an impact on man's environment,” as specified by §1507.2.
(b) Identify environmental effects and values in adequate detail so they can be compared to economic and technical analyses. Environmental documents and appropriate analyses shall be circulated and reviewed at the same time as other planning documents.
(c) Study, develop, and describe appropriate alternatives to recommended courses of action in any proposal which involves unresolved conflicts concerning alternative uses of available resources as provided by section 102(2)(E) of the Act.
(d) Provide for cases where actions are planned by private applicants or other non-Federal entities before Federal involvement so that:
(1) Policies or designated staff are available to advise potential applicants of studies or other information foreseeably required for later Federal action.
(2) The Federal agency consults early with appropriate State and local agencies and Indian tribes and with interested private persons and organizations when its own involvement is reasonably foreseeable.
(3) The Federal agency commences its NEPA process at the earliest possible time.
40 CFR 1501.3: When to prepare an environmental assessment
(a) Agencies shall prepare an environmental assessment (§1508.9) when necessary under the procedures adopted by individual agencies to supplement these regulations as described in §1507.3. An assessment is not necessary if the agency has decided to prepare an environmental impact statement.
(b) Agencies may prepare an environmental assessment on any action at any time in order to assist agency planning and decisionmaking.
40 CFR 1501.4: Whether to prepare an environmental impact statement
In determining whether to prepare an environmental impact statement the Federal agency shall:
(a) Determine under its procedures supplementing these regulations (described in §1507.3) whether the proposal is one which:
(1) Normally requires an environmental impact statement, or
(2) Normally does not require either an environmental impact statement or an environmental assessment (categorical exclusion).
(b) If the proposed action is not covered by paragraph (a) of this section, prepare an environmental assessment (§1508.9). The agency shall involve environmental agencies, applicants, and the public, to the extent practicable, in preparing assessments required by §1508.9(a)(1).
(c) Based on the environmental assessment make its determination whether to prepare an environmental impact statement.
(d) Commence the scoping process (§1501.7), if the agency will prepare an environmental impact statement.
(e) Prepare a finding of no significant impact (§1508.13), if the agency determines on the basis of the environmental assessment not to prepare a statement.
(1) The agency shall make the finding of no significant impact available to the affected public as specified in §1506.6.
(2) In certain limited circumstances, which the agency may cover in its procedures under §1507.3, the agency shall make the finding of no significant impact available for public review (including State and areawide clearinghouses) for 30 days before the agency makes its final determination whether to prepare an environmental impact statement and before the action may begin. The circumstances are:
(i) The proposed action is, or is closely similar to, one which normally requires the preparation of an environmental impact statement under the procedures adopted by the agency pursuant to §1507.3, or
(ii) The nature of the proposed action is one without precedent.
40 CFR 1501.6: Cooperating agencies
The purpose of this section is to emphasize agency cooperation early in the NEPA process. Upon request of the lead agency, any other Federal agency which has jurisdiction by law shall be a cooperating agency. In addition any other Federal agency which has special expertise with respect to any environmental issue, which should be addressed in the statement may be a cooperating agency upon request of the lead agency. An agency may request the lead agency to designate it a cooperating agency.
(a) The lead agency shall:
(1) Request the participation of each cooperating agency in the NEPA process at the earliest possible time.
(2) Use the environmental analysis and proposals of cooperating agencies with jurisdiction by law or special expertise, to the maximum extent possible consistent with its responsibility as lead agency.
(3) Meet with a cooperating agency at the latter's request.
(b) Each cooperating agency shall:
(1) Participate in the NEPA process at the earliest possible time.
(2) Participate in the scoping process (described below in §1501.7).
(3) Assume on request of the lead agency responsibility for developing information and preparing environmental analyses including portions of the environmental impact statement concerning which the cooperating agency has special expertise.
(4) Make available staff support at the lead agency's request to enhance the latter's interdisciplinary capability.
(5) Normally use its own funds. The lead agency shall, to the extent available funds permit, fund those major activities or analyses it requests from cooperating agencies. Potential lead agencies shall include such funding requirements in their budget requests.
(c) A cooperating agency may in response to a lead agency's request for assistance in preparing the environmental impact statement (described in paragraph (b)(3), (4), or (5) of this section) reply that other program commitments preclude any involvement or the degree of involvement requested in the action that is the subject of the environmental impact statement. A copy of this reply shall be submitted to the Council.
40 CFR 1501.7: Scoping
There shall be an early and open process for determining the scope of issues to be addressed and for identifying the significant issues related to a proposed action. This process shall be termed scoping. As soon as practicable after its decision to prepare an environmental impact statement and before the scoping process the lead agency shall publish a notice of intent (§1508.22) in the Federal Register except as provided in §1507.3(e).
(a) As part of the scoping process the lead agency shall:
(1) Invite the participation of affected Federal, State, and local agencies, any affected Indian tribe, the proponent of the action, and other interested persons (including those who might not be in accord with the action on environmental grounds), unless there is a limited exception under §1507.3(c). An agency may give notice in accordance with §1506.6.
(2) Determine the scope (§1508.25) and the significant issues to be analyzed in depth in the environmental impact statement.
(3) Identify and eliminate from detailed study the issues which are not significant or which have been covered by prior environmental review (§1506.3), narrowing the discussion of these issues in the statement to a brief presentation of why they will not have a significant effect on the human environment or providing a reference to their coverage elsewhere.
(4) Allocate assignments for preparation of the environmental impact statement among the lead and cooperating agencies, with the lead agency retaining responsibility for the statement.
(5) Indicate any public environmental assessments and other environmental impact statements which are being or will be prepared that are related to but are not part of the scope of the impact statement under consideration.
(6) Identify other environmental review and consultation requirements so the lead and cooperating agencies may prepare other required analyses and studies concurrently with, and integrated with, the environmental impact statement as provided in §1502.25.
(7) Indicate the relationship between the timing of the preparation of environmental analyses and the agency's tentative planning and decisionmaking schedule.
(b) As part of the scoping process the lead agency may:
(1) Set page limits on environmental documents (§1502.7).
(2) Set time limits (§1501.8).
(3) Adopt procedures under §1507.3 to combine its environmental assessment process with its scoping process.
(4) Hold an early scoping meeting or meetings which may be integrated with any other early planning meeting the agency has. Such a scoping meeting will often be appropriate when the impacts of a particular action are confined to specific sites.
(c) An agency shall revise the determinations made under paragraphs (a) and (b) of this section if substantial changes are made later in the proposed action, or if significant new circumstances or information arise which bear on the proposal or its impacts.
