deliveries within the ± 5% imbalance tolerance.

 

(b) For the determination of monthly imbalances, shippers'

receipt or delivery volumes at each MAP point shall be allocated according to

the interconnecting operational balancing agreement (OBA) or pre-determined

based on each shipper's scheduled nomination.

 

(c) When adjustments become operationally necessary, adjustments

at each MAP point will be determined according to the OBA or PDA in place at

the time the volumes were received or delivered. Absent an OBA or PDA,

adjustments will be pro rata according to each shipper's daily scheduled

nomination.

 

(d) Questar will make monthly imbalance information available to

all shippers through Questline on or before the 9th business day of each

month following the month during which gas was transported. An imbalance

statement will be tendered to shipper with shipper's monthly bill issued

according to Section 18.1(b) of these General Terms and Conditions.
