When an emergency exists and the Agency determines that it is necessary to take emergency action before preparing a NEPA analysis and any required documentation, the provisions of this section apply.

Urgent response. The Agency and the applicant, as appropriate, may take actions necessary to control the immediate impacts of an emergency (see § 1970.53(e)). Emergency actions include those that are urgently needed to restore services and to mitigate harm to life, property, or important natural or cultural resources. When taking such actions, the Agency and the applicant, when applicable, will take into account the probable environmental consequences of the emergency action and mitigate foreseeable adverse environmental effects to the extent practicable.

CE- and EA-level actions. If the Agency proposes longer-term emergency actions other than those actions described in paragraph (a) of this section, and such actions are not likely to have significant environmental impacts, the Agency will document that determination in a finding for a CE or in a FONSI for an EA prepared in accordance with this part. If the Agency finds that the nature and scope of proposed emergency actions are such that they must be undertaken prior to preparing any NEPA analysis and documentation associated with a CE or EA, the Agency will identify alternative arrangements for compliance with this part with the appropriate agencies.

Alternative arrangements for environmental compliance are limited to actions necessary to control the immediate impacts of the emergency.

Alternative arrangements will, to the extent practicable, attempt to achieve the substantive requirements of this part.

EIS-level actions. If the Agency proposes emergency actions other than those actions described in paragraphs (a) or (b) of this section and such actions are likely to have significant environmental impacts, then the Agency will consult with the CEQ about alternative arrangements in accordance with CEQ regulations at 40 CFR 1506.11 as soon as possible.
