"...each agency shall take all appropriate actions to establish, maintain, and, as necessary, revise an order of succession, or to propose presidential action to establish or revise an order of succession."
"(b) "order of succession" means a list of officials by position who shall act as and perform the functions and duties of the office of the head of the agency in the event that the office-holder has died, resigned, or otherwise become unable to perform the functions and duties of the office. "Order of succession" does not include any order, rule, memorandum, or other document delegating or partially delegating the authority of an office."

"(c) Not later than 30 days from the date of this order, and not later than 7 days from the issuance date of any subsequent final revision to an existing order of succession, each agency described in subsection 4(a) of this order shall provide a copy of its order of succession to the Counsel to the President, the Assistant to the President for Homeland Security and Counterterrorism, and the Director of the Office of Management and Budget."
"(b) Nothing in this order shall be construed to delegate the President's authority under the Federal Vacancies Reform Act of 1998, 5 U.S.C. 3345 et seq., to designate individuals to perform the functions and duties of a vacant office temporarily in an acting capacity."
