GENERAL TERMS AND CONDITIONS

(Continued)

 

9. PRIORITY, CURTAILMENT AND INTERRUPTION OF SERVICE

 

9.1 Priority. Cushion gas injected by Questar and storage service

required by Questar for its transmission system load balancing and operational

control shall have priority over the classes of service set forth below.

Subsequent to this priority, shippers receiving service in Clay Basin shall be

entitled to injection, storage and withdrawal of gas, subject to availability

of storage capacity and as otherwise provided, in the following order:

 

(a) FSS service.

(b) PAL1 service.

(c) ISS service.

(d) Authorized overrun service.

(e) PAL2 service.

 

Provided, however, that the priority of service for shippers utilizing the

PAL1 compressor shall be determined by Part 4 of this tariff.

 

If, in Questar's judgement, operating conditions such as reservoir

inventory and projected FSS shipper activities indicate that working-gas

capacity utilized by ISS shippers will be required to meet the requirements of

FSS shippers, ISS shippers must withdraw, as directed by Questar, all or a

portion of their working-gas inventory within 30 days of notice. If ISS or

PAL2 shippers are required to withdraw a portion of their working-gas

inventory, the order of withdrawals will be based on the inventory rate paid,

with the ISS shipper paying the lowest rate being required to withdraw its

working gas first. In the event two or more shippers are paying the same

rate, required withdrawals will be pro rata based on working-gas inventory.

 

ISS shippers that have been given notice to withdraw their working gas

may transfer the working gas to an FSS shipper's working-gas account as an

alternative to withdrawal.

 

Except for reasons of force majeure or curtailment, any gas not

withdrawn from storage at the end of the 30 days subsequent to notification

may, at Questar's option, and without undue discrimination, be retained by

and become the property of Questar, without charge, and shall be free and

clear of any adverse claim.
