4. INTERRUPTION OF SERVICE

-----------------------

 

Firm service under this Rate Schedule shall have the highest scheduling priority of

Northern's storage services. In addition, service under this Rate Schedule shall be

subject to interruption under the terms of the upstream or downstream Firm or

Interruptible Throughput Service Agreement(s). Any limitations imposed by such

Throughput Service Agreements shall have precedence over Shipper's rights to service

herein.

 

In the event that Northern is required to allocate capacity on its system, service

under this Rate Schedule may be constrained by the allocation of capacity to the

applicable Transportation Service Agreement.

 

5. OFFERING OF SERVICE

-------------------

 

Available FDD capacity will be posted on Northern's Internet website. Northern shall

accept requests for service under this Rate Schedule for FDD quantities available. Such

requests must contain information required to initiate service as defined in Section 27,

"Information Required for a Request for Service," of the "GENERAL TERMS AND CONDITIONS" of

this Tariff. Priority for service shall be based on the price and term offered by the

Shipper. For the purposes of allocating capacity, Shippers willing to pay more than the

maximum tariff rate will be considered to be paying the maximum tariff rate. Northern,

upon receiving such requests including all information required to initiate service, shall

notify Shipper of the quantity of FDD capacity available and any inability to provide the

service requested. Any allocations required as a result of receiving matching offers will

be on a pro rata basis.
