PART 2

GENERNAL TERMS AND CONDITIONS

(Continued)

(b) As soon as practicable following the completion of each

withdrawal period, Questar will determine, according to its normal operating

practices and procedures, the volume of working gas in each peaking storage

reservoir that became non-recoverable during the previous annual storage

cycle. The non-recoverable working gas at each reservoir shall be allocated to

the PAL2 service account and to the account of each shipper that utilized the

reservoir during the previous annual storage cycle based on the ratio of each

accounts' gross working gas in that reservoir during its previous annual

storage cycle to the sum of the gross working gas of all accounts that

utilized that reservoir during the previous annual storage cycle.

Questar shall inform all shippers of the results of the determination. If any

shipper's actual working gas withdrawals from a particular aquifer storage

reservoir are found to exceed the difference between the shipper's gross

working gas and the shipper's allocated share of the non-recoverable working

gas in that reservoir during the previous annual storage cycle, the shipper

shall be solely responsible for reconciling such imbalance with all other

shippers that utilized the reservoir during the previous annual storage cycle.
