3.8 Partial Curtailment or Full Interruption of Scheduled Capacity (Continued)


3.8.1 Allocation of Scheduled Capacity Due to Capacity Limitations (Continued)


Once scheduled, Rate Schedule FT-A, FT-C and FT-GS Shippers with

secondary capacity scheduling rights at a given point shall be

considered to have an equal curtailment allocation priority with Rate

Schedule FT-A, FT-C and FT-GS Shippers with primary capacity scheduling

rights at such point.


3.8.2 Allocation of Scheduled Capacity Due to Loss of Line Pack


If Company experiences an unanticipated loss of line pack due to the

under delivery of gas quantities by Shipper(s) to Company's mainline,



(i) if the deficient source is known, Company will curtail the

corresponding scheduled firm and/or interruptible markets; or


(ii) if the deficient sources are undeterminable, then Company will

localize the smallest affected area, and will curtail scheduled

interruptible service first in reverse scheduling order and then

scheduled firm services will be curtailed pro rata; provided that

verifiable Receipt Point gas quantities will not be subject to a

deficiency of receipts curtailment.


To the extent that information concerning the deficient source is, or

becomes available, Company will provide such information via the System

to all curtailed Shippers.


3.9 Shipper Imbalances


3.9.1 Shipper's Duty to Control Imbalances


A Shipper receiving any transportation service from Company will use,

or will cause any party receiving or delivering Shipper's gas to use

all reasonable efforts to ensure that receipts and deliveries of gas

equal the Scheduled Quantities.


A Shipper receiving service from Company at a Receipt and/or Delivery

Point(s) not covered by an Operational Balancing Agreement shall also

be responsible for controlling, and if necessary, adjusting receipts

and deliveries of gas to maintain a balance between such receipts,

deliveries, and the corresponding Scheduled Quantities.


To the extent a Shipper is out of balance at a point not covered by an

Operational Balancing Agreement, such Shipper will be subject to the

daily and monthly balancing provisions contained in the Rate

Schedule LMS-MA for Delivery Points or Company's Rate Schedule LMS-PA

for Receipt Points. Imbalances at such points will be allocated

pro rata based on Scheduled Quantities.
