When NASA determines that emergency circumstances exist which make it necessary to take immediate response and/or recovery action(s) before preparing a NEPA analysis, then the following provisions apply:
(a) NASA may undertake immediate emergency response and/or recovery action(s) necessary to protect life, property, or important natural, cultural, or historic resources. When taking such action(s), NASA shall, to the extent practicable, mitigate reasonably foreseeable adverse environmental impacts.
(b) If NASA proposes emergency response and/or recovery actions that will continue beyond those needed to immediately protect life, property, and important natural, cultural, or historic resources, NASA shall determine the appropriate level of NEPA compliance.
(c) If continuation of the emergency actions will reasonably result in significant environmental impacts, NASA shall notify CEQ about alternative arrangements for compliance.
