PART 3

GENERAL TERMS AND CONDITIONS

(Continued)

10.5 Injection and Withdrawal of Gas.

(a) Questar may, but shall not be obligated to accept gas for

injection into any storage reservoir nor be required to withdraw gas from any

storage reservoir outside the respective injection and withdrawal periods.

(b) A shipper receiving storage service under Rate Schedule FSS

shall schedule the withdrawal of, or transfer to another storage or park and

loan account, all of its recoverable working gas by the end of the term of its

storage service agreement. At least six months prior to the pending

expiration of an FSS service agreement, Questar will give notice that the

shipper must withdraw or transfer to another storage or park and loan account,

its recoverable working gas prior to expiration of the service agreement.

Regardless of whether a service agreement expires or if shipper chooses

to exercise its right to terminate its service agreement, the following

procedure will be used for any gas remaining under the expired or terminated

service agreement: If an FSS shipper has not removed all gas stored under

its expired or terminated service agreement, Questar will, within three

business days, sell the quantities of gas involved and distribute the

proceeds to the shipper less any administrative costs incurred by Questar.

shall schedule the withdrawal of all of its recoverable working gas by the

end of the term of its storage-service agreement. If an ISS shipper has not

withdrawn all of its working gas prior to the termination of its service

agreement, the shipper, at the date of service agreement termination, may

transfer its working gas to an FSS shipper's working-gas account or, if

sufficient unutilized annual working-gas capacity is available, the shipper

may be given additional time in which to withdraw its working gas, provided

that during such time shipper will pay the maximum ISS inventory rate for all

gas remaining in storage notwithstanding any previously negotiated discounts.

Withdrawals will only be allowed after all firm, interruptible and overrun

requests are met. Questar will not compensate shipper for any benefit

obtained by any other shipper receiving storage service and shall not incur

any other liability whatsoever. If the annual working-gas capacity utilized

by ISS shippers under terminated service agreements is required by FSS

shippers,
