to maintain the overall operational integrity of all or a portion of

Trailblazer's system. A Critical Time may not be declared on all or a

notify Shippers via DART by 4:00 p.m. Central Time that they should

check DART again at a specified later time to see whether a Critical

Time will be in effect for the next day. Trailblazer must attempt to

give actual notice of a Critical Time via telefax or telephone

(provided a Shipper has given the numbers to Trailblazer as required

in Section 40.1) at least four (4) hours prior to the start of the

day before a Critical Time will be effective as to a Shipper. Such

notice shall specify the anticipated duration of the Critical Time.

A Critical Time will be effective at the start of a day and will

continue until the end of the day and through the end of successive

days until Trailblazer notifies Shippers via DART that there is no

longer a Critical Time.
