Section 10




10.3 Critical Period - "Critical Period" refers to situations where in

Gulf South's reasonable judgement 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 South may

temporarily suspend pooling, segmentation, 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 hurricane has entered or is approaching the Gulf of

Mexico; (2) a supply point loses production for an undetermined

or extended period; (3) weather conditions (changes in

temperature, precipitation, and/or wind conditions) are predicted

to occur that will significantly increase the demand for system

capacity above current nominated levels and/or projected NNS

demand, and which could reduce operational flexibility or

reliability; or (4) 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

South's operational flexibility.


When Gulf South declares that a Critical Period exists, it shall

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

telephone call to affected Customers' dispatch number unless

Customer has designated another preferred format for

notification. Within 24 hours following the termination of a

Critical Period, Gulf South 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.
