§900.201   Environmental review process.

(a) General. The environmental review process is the investigation of potential environmental impacts to determine the environmental process to be followed and to assist in the preparation of the environmental document.

(b) Early coordination. Applicants will contact the Commission and work with the Approving Official to begin the environmental review process as soon as Denali Commission assistance is projected. Environmental issues shall be identified and considered early in the proposal planning process. A systematic, interdisciplinary approach that includes community involvement and intergovernmental coordination to expand the potential sources of information and identify areas of concern will be used. Environmental permits and other forms of approval, concurrence, or consultation may be required. The planning process shall include permitting and other review processes to ensure that necessary information will be collected and provided to permitting and reviewing agencies in a timely manner.

§900.202   Emergency actions.

(a) General. Emergency circumstances may require immediate actions that preclude following standard NEPA processes. The Council shall limit alternative arrangements to those actions that are necessary to control the immediate impacts of the emergency. In the event of emergency circumstances, the Approving Official should coordinate with the Federal Co-Chair as soon as practicable. Immediate emergency actions necessary to protect the lives and safety of the public or prevent adverse impacts to ecological resources and functions should never be delayed in order to comply with these NEPA procedures. Alternative arrangements for NEPA compliance are permitted for emergency actions pursuant to paragraphs (b) through (d) of this section.

(b) Categorical exclusion (CATEX). When emergency circumstances make it necessary to determine whether an extraordinary circumstance would preclude the use of a CATEX, the Approving Official shall make the determination as soon as practicable. If an extraordinary circumstance exists, the Approving Official shall comply with paragraphs (c) and (d) of this section, as applicable.

(c) Environmental assessment (EA). When emergency circumstances make it necessary to take an action that requires an EA before the EA can be completed, the Approving Official will consult with the Federal Co-Chair to develop alternative arrangements to meet the requirements of these NEPA implementing procedures and CEQ Regulations pertaining to EAs. Alternative arrangements should focus on minimizing adverse environmental impacts of the proposed action and the emergency. To the maximum extent practicable, these alternative arrangements should include the content, interagency coordination, and public notification and involvement that would normally be undertaken for an EA for the action at issue and cannot alter the requirements of the CEQ Regulations at 40 CFR 1508.9(a)(1) and (b). The Federal Co-Chair may grant an alternative arrangement. Any alternative arrangement shall be documented. The Federal Co-Chair will inform CEQ of the alternative arrangements at the earliest opportunity.

(d) Environmental Impact Statement (EIS). Where emergency circumstances make it necessary to take actions with significant environmental impacts without observing other provisions of these NEPA implementing procedures and the CEQ Regulations (see 40 CFR 1506.11) the Federal Co-Chair may consult with CEQ about alternative arrangements for implementation of NEPA. In these situations, the Commission may reduce processing times or, if the emergency situation warrants, abbreviate its preparation and processing of EISs. Any request for alternative arrangements must be submitted by the Federal Co-Chair to CEQ and notice of a potential request should be provided to CEQ at the earliest opportunity. For projects undertaken by an applicant, the Approving Official will inform the Federal Co-Chair about the emergency. The Federal Co-Chair will consult CEQ requesting the alternative arrangements for complying with NEPA.

§900.203   Determination of federal actions.

(a) The Commission shall determine whether any Commission proposal:

(1) Is categorically excluded from preparation of either an EA or an EIS;

(2) Requires preparation of an EA; or

(3) Requires preparation of an EIS.

(b) Notwithstanding any other provision of this part, the Commission may prepare a NEPA document to assist any Commission action at any time in order to further the purposes of NEPA. This NEPA document may be done to analyze the consequences of ongoing Commission activities, to support Commission planning, to assess the need for mitigation, to disclose fully the potential environmental consequences of Commission actions, or for any other reason. Documents prepared under this paragraph shall be prepared in the same manner as Commission documents prepared under this part.

§900.204   Categorical exclusions.

(a) General. A categorical exclusion (CATEX) is defined in 40 CFR 1508.4 as a category of actions which do not individually or cumulatively have a significant effect on the human environment and, for which in the absence of extraordinary circumstances or sensitive resources, neither an EA nor an EIS is required. Actions that meet the conditions in paragraph (b) of this section and are listed in section A of appendix A of this part can be categorically excluded from further analysis and documentation in an EA or EIS. Actions that meet the screening conditions in paragraph (b) of this section and are listed in section B of appendix A require satisfactory completion of a Denali Commission CATEX checklist in order to be categorically excluded from further analysis and documentation in an EA or EIS.

(b) Conditions. The following three conditions must be met for an action to be categorically excluded from further analysis in an EA or EIS.

(1) The action has not been segmented (too narrowly defined or broken down into small parts in order minimize its potential effects and avoid a higher level of NEPA review) and its scope includes the consideration of connected actions and, when evaluating extraordinary circumstances, cumulative impacts.

(2) No extraordinary circumstances described in paragraph (c) of this section exist, unless resolved through other regulatory means.

(3) One categorical exclusion described in either section of appendix A of this part encompasses the proposed action.

(c) Extraordinary circumstances. Any action that normally would be classified as a CATEX but could involve extraordinary circumstances will require appropriate environmental review documented in a Denali Commission CATEX checklist to determine if the CATEX classification is proper or if an EA or EIS should be prepared. Extraordinary circumstances to be considered include those likely to:

(1) Have a reasonable likelihood of significant impacts on public health, public safety, or the environment;

(2) Have effects on the environment that are likely to be highly controversial or involve unresolved conflicts concerning alternative uses of available resources;

(3) Have possible effects on the human environment that are highly uncertain, involve unique or unknown risks, or are scientifically controversial;

(4) Establish a precedent for future action or represent a decision in principle about future actions with potentially significant environmental effects;

(5) Relate to other actions with individually insignificant but cumulatively significant environmental effects;

(6) Have a greater scope or size than is normal for the category of action;

(7) Have the potential to degrade already existing poor environmental conditions or to initiate a degrading influence, activity, or effect in areas not already significantly modified from their natural condition;

(8) Have a disproportionately high and adverse effect on low income or minority populations (see Executive Order 12898);

(9) Limit access to and ceremonial use of Indian sacred sites on federal lands by Indian religious practitioners or adversely affect the physical integrity of such sacred sites (see Executive Order 13007);

(10) Threaten a violation of a federal, tribal, state or local law or requirement imposed for the protection of the environment;

(11) Have a reasonable likelihood of significant impact to subsistence activities; or

(12) Have a reasonable likelihood of significant impacts on environmentally sensitive resources, such as:

(i) Properties listed, or eligible for listing, in the National Register of Historic Places;

(ii) Species listed, or proposed to be listed, on the List of Endangered or Threatened Species, or their habitat; or

(iii) Natural resources and unique geographic characteristics such as historic or cultural resources; park, recreation or refuge lands; wilderness areas; wild or scenic rivers; national natural landmarks; sole or principal drinking water aquifers; prime farmlands; special aquatic sites (defined under Section 404 of the Clean Water Act); floodplains; national monuments; and other ecologically significant or critical areas.

§900.205   Environmental assessment.

(a) An EA is required for all proposals, except those exempt from NEPA or categorically excluded under this part, and those requiring or determined to require an EIS. EAs provide sufficient evidence and analysis to determine whether to prepare an EIS or a finding of no significant impact (FONSI).

(b) In addition, an EA may be prepared on any action at any time in order to assist in planning and decision making, to aid in the Commission's compliance with NEPA when no EIS is necessary, or to facilitate EIS preparation.

(c) EAs shall be prepared in accordance with subpart C of this part and shall contain analyses to support conclusions regarding environmental impacts. If a FONSI is proposed, it shall be prepared in accordance with §900.305.

§900.206   Environmental impact statement.

An EIS is required when the project is determined to have a potentially significant impact on the human environment. EISs shall be prepared in accordance with subpart D of this part.

§900.207   Programmatic environmental reviews.

(a) A programmatic NEPA review is used to assess the environmental impacts of a proposed action that is broad in reach, such as a program, plan, or policy (see 40 CFR 1502.4). Analyses of subsequent actions that fall within the program, plan, or policy may be tiered to the programmatic review, as described in 40 CFR 1502.20 and 1508.28.

(b) Programmatic NEPA reviews may take the form of a programmatic EA or a programmatic EIS.

(c) A programmatic EA shall meet all of the requirements for EAs in subpart C of this part, including those for content and public involvement. In order to adopt a programmatic EA prepared by another agency that did not provide the same public involvement opportunities as the Commission, the Commission shall provide notice of the availability of the programmatic EA and make it available for public comment consistent with §900.303(b) and (c) before adopting it.

(d) A programmatic EIS shall meet all of the requirements for EISs in subpart D of this part and in 40 CFR parts 1500 through 1508.
