6.3 Adjustments to Confirmation Quantities Received by Transporter in

the Event of Supply Underperformance (Continued)


(c) (i) Receipts from Interconnects shall be monitored by

Transporter on a daily basis where real time data is

available. When actual receipts are less than

confirmed quantities and the shortfall in receipts

threatens the integrity of Transporter's system,

Transporter shall notify the Operator and request the

Operator to increase deliveries or reduce confirmed

quantities prospectively.


(ii) In the event an Operator fails to make adjustments,

Transporter shall limit, on a pro rata basis,

prospective confirmed quantities to actual receipts of

supply on the Day in question. Higher confirmations

shall be allowed prospectively only when the Operator

increases quantities of gas into Transporter's system.


6.4 Capacity Allocation in the Event of Force Majeure or Required

Maintenance. If Transporter determines that its available

capacity is reduced due to force majeure or required maintenance,

Transporter shall allocate all available capacity first to all

primary service on a proportionate basis and then to all alternate

service on a proportionate basis. Contract maximum Receipt or

Delivery Point quantities shall be used to determine capacity

allocations, if any, at a primary receipt or primary delivery

point. When there is a constraint along a Flow Path, the contract

Path Quantity at or through the constraint shall be used to

determine primary capacity allocations at or through such



(a) Should multiple simultaneous events occur requiring

Transporter to allocate available capacity, Transporter will

schedule all available capacity by resolving the most

constrained point (defined as the largest difference between

confirmed nominations and operational available capacity)

first. If further allocations are necessary, Transporter

will continue to resolve the most constrained point until all

constraints are resolved.
