GENERNAL TERMS AND CONDITIONS

(Continued)

8. PRIORITY AND CURTAILMENT OF PEAKING STORAGE SERVICE

8.1 Priority. A shipper receiving service at Questar's peaking

storage reservoirs shall be entitled to service, subject to the availability

of capacity, in the following order of priority:

(a) Peaking storage service provided to Questar Gas Company

(Questar Gas), Questar's former sale-for-resale customer. At the time peaking

storage service commences under Rate Schedule PKS, Questar Gas shall have

first priority to 100% of the storage capacity at each aquifer storage

reservoir.

(b) Shippers that have executed service agreements with Questar

under Rate Schedule PKS after the effective date of this tariff.

(c) All PAL2 service by rate paid, from highest to lowest.

Where two or more shippers are paying the same rate, available capacity will

be awarded to those shippers paying the same rate in equal amounts up to the

level requested. This procedure will continue until (1) all requests are

filled or (2) all available capacity is utilized.

8.2 Curtailment.

(a) If, due to any cause, Questar does not have sufficient

injection or withdrawal capacity at a particular peaking storage reservoir on

any day to serve all of its shippers, curtailment of storage service at that

reservoir shall be pro rata based on the allocation formula set forth in § 9.2

of this Part 2.

(b) Questar shall provide shipper as much advance notice of any

curtailment as is practicable under the circumstances. Such notice shall

state the reduced quantities of gas that Questar estimates it will be able to

inject or withdraw for shipper and the estimated duration of the curtailment.
