((a)) Whenever the President, after investigation, finds that changes in the organization of agencies are necessary to carry out any policy set forth in , he shall prepare a reorganization plan specifying the reorganizations he finds are necessary. Any plan may provide for—
((1)) the transfer of the whole or a part of an agency, or of the whole or a part of the functions thereof, to the jurisdiction and control of another agency;
((2)) the abolition of all or a part of the functions of an agency, except that no enforcement function or statutory program shall be abolished by the plan;
((3)) the consolidation or coordination of the whole or a part of an agency, or of the whole or a part of the functions thereof, with the whole or a part of another agency or the functions thereof;
((4)) the consolidation or coordination of part of an agency or the functions thereof with another part of the same agency or the functions thereof;
((5)) the authorization of an officer to delegate any of his functions; or
((6)) the abolition of the whole or a part of an agency which agency or part does not have, or on the taking effect of the reorganization plan will not have, any functions.
((b)) The President shall have a reorganization plan delivered to both Houses on the same day and to each House while it is in session, except that no more than three plans may be pending before the Congress at one time. In his message transmitting a reorganization plan, the President shall specify with respect to each abolition of a function included in the plan the statutory authority for the exercise of the function. The message shall also estimate any reduction or increase in expenditures (itemized so far as practicable), and describe any improvements in management, delivery of Federal services, execution of the laws, and increases in efficiency of Government operations, which it is expected will be realized as a result of the reorganizations included in the plan. In addition, the President’s message shall include an implementation section which shall (1) describe in detail (A) the actions necessary or planned to complete the reorganization, (B) the anticipated nature and substance of any orders, directives, and other administrative and operational actions which are expected to be required for completing or implementing the reorganization, and (C) any preliminary actions which have been taken in the implementation process, and (2) contain a projected timetable for completion of the implementation process. The President shall also submit such further background or other information as the Congress may require for its consideration of the plan.
((c)) Any time during the period of 60 calendar days of continuous session of Congress after the date on which the plan is transmitted to it, but before any resolution described in section 909 has been ordered reported in either House, the President may make amendments or modifications to the plan, consistent with sections 903–905 of this title, which modifications or revisions shall thereafter be treated as a part of the reorganization plan originally transmitted and shall not affect in any way the time limits otherwise provided for in this chapter. The President may withdraw the plan any time prior to the conclusion of 90 calendar days of continuous session of Congress following the date on which the plan is submitted to Congress.
