GENERAL TERMS AND CONDITIONS

 

10.2 Interruption and Curtailment Procedures.

 

(a) If, due to any cause whatsoever, Southern Trails does not

have sufficient capacity in all or part of its transmission system on any day

to serve all of its customers, curtailment or interruptions will be instituted

in reverse order of priority of classes specified in this section. However,

once the gas day commences, all firm Shippers on the affected parts of the

transmission system will be curtailed pro rata, regardless of whether gas has

been scheduled at a primary or alternate receipt or delivery point.

 

(b) If curtailment or interruption is required, Southern Trails

and Shipper shall cooperate to the extent possible in making adjustments to

receipts or deliveries to minimize injury to any property or facilities.

 

(c) Nothing in this provision shall limit Southern Trails' right

to curtail or interrupt service on any other reasonable basis (including pro

rata curtailment or interruption within a class of service) in order to ensure

system integrity or to reflect the operational characteristics of Southern

Trails' system.

 

10.3 Notice of Interruption. Southern Trails shall provide Shipper as

much advance notice of interruption as is possible under the circumstances.

Southern Trails will support notification, to be designated by Shipper, and

mutually agreed to, through the following channels: (1) available on

Questline's shipper web reports and/or (2) up to two internet e-mail addresses

provided by Shipper or (3) additional electronic notification specified by

Shipper. Such notice shall state the estimated reduced quantities of gas that

can be transported.

 

10.4 Causes. Southern Trails shall have the right, without liability

to Shipper, to interrupt or curtail the transportation of gas for Shipper for

reasons of force majeure; or when necessary, to test, alter, modify, enlarge

or repair any facility or property comprising a part of, or appurtenant to,

Southern Trails' pipeline system, or any other reasons necessary for safe and

efficient operation of its system. Southern Trails shall endeavor to cause a

minimum of inconvenience to Shipper because of such interruptions.

 

11. USE OF RECEIPT AND DELIVERY POINTS

 

11.1 Designation of Primary Receipt and Delivery Points. Shipper's

primary receipt points must be assigned by the Shipper to corresponding

primary delivery points, subject to available capacity. The total RDC

assigned to Shipper's receipt points must equal the RDC assigned to the

corresponding delivery points. The sum of the receipt point RDC and delivery

point RDC must equal the RDC shown in Shipper's Rate Schedule FT service

agreement.
