The timeline and other applicable procedures for the submission,

A timely nomination may be modified either by a superseding

timely nomination or by an intra-day nomination. A timely

nomination which is superseded by an intra-day nomination shall,

at the conclusion of the day on which the intra-day nomination

was in effect, revert to the quantities, locations, and end date

submitted in the superseded timely nomination. A timely

nomination which is superseded by a timely nomination shall, at

the conclusion of the end date in the superseding timely nomi-

nation, revert to the quantities, locations, and end date

submitted in the superseded timely nomination.
