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.
