Section 18




18.3 Critical Period - "Critical Period" refers to situations where,

in Gulf Crossing's reasonable judgment, general system

flexibility, normally available Day to Day, cannot be afforded to

customers to accommodate minor variations in receipt and delivery

quantities from scheduled levels. During such periods, Gulf

Crossing may temporarily suspend segmentation, pooling, or OBA's

to assist in the management of the pipeline system.


Examples of such operating conditions include but are not limited

to (1) a supply point loses production for an undetermined or

extended period; (2) weather conditions (changes in temperature,

precipitation, and/or wind conditions) are predicted to occur

that will significantly increase or decrease the demand for

system capacity from current nominated levels and which could

reduce operational flexibility or reliability; or (3) the system

is experiencing imbalances that, if left uncorrected, would

threaten the operational integrity of the system or some portion

thereof, or otherwise reduce Gulf Crossing's operational



When Gulf Crossing declares that a Critical Period exists, it

shall post a timely notice on its Internet Web Site followed by

an e-mail unless Customer has designated another preferred format

for notification. Within 24 hours following the termination of a

Critical Period, Gulf Crossing shall post on its Internet Web

Site the reasons why a Critical Period was declared and what

events resulted in the Critical Period being lifted.
