18 CFR 1318.507: Emergency actions.

(a) TVA may consolidate, modify, or omit provisions of these procedures for actions necessary in an emergency and ensure such changes would substantially comply with the intent of these procedures.

(b) Where emergency circumstances make it necessary to take an action with significant environmental impact without observing the provisions of these regulations, TVA will consult with the CEQ about alternative arrangements for those actions necessary to control the immediate impacts of the emergency.

(c) TVA will document the determination that an emergency exists and describe the responsive action(s) taken at the time the emergency exists. The form and content of that documentation is within TVA's discretion.
