42 U.S. Code § 6421 - Procedure for Congressional review of Presidential requests to implement certain authorities
For purposes of this section, the term “energy action” means any matter required to be transmitted, or submitted to the Congress in accordance with the procedures of this section.
The President shall transmit any energy action (bearing an identification number) to both Houses of Congress on the same day. If both Houses are not in session on the day any energy action is received by the appropriate officers of each House, for purposes of this section such energy action shall be deemed to have been transmitted on the first succeeding day on which both Houses are in session.
Under provisions contained in an energy action, a provision of such an action may take effect on a date later than the date on which such action otherwise takes effect pursuant to the provisions of this section.
