12.5 Imbalance Payback Option. Subject to available transportation

and/or storage capacity, operational constraints and approval by Questar, a

shipper during the remainder of the month after notification of its monthly

imbalance, may eliminate its prior month's imbalance through either a physical

payback or take of gas in lieu of or in connection with imbalance trading.

Nominations to reduce the previous Monthly Imbalance must be specifically

designated for that purpose. Questar will consider each shipper's request to

exercise its option under this section and will, on a nondiscriminatory basis,

and subject to prudent operational practices, honor the request.


12.6 Cashout.


All remaining imbalances that exceed the imbalance tolerance at the end

of the month will be subject to the following cashout provisions. However, if

shipper cannot cure an imbalance due to force majeure, Questar will extend the

time period for the shipper to pay back an imbalance for a period equal to the

length of the force majeure event.



(a) Cashout volumes are those volumes that exceed the ±5%

imbalance tolerance at the end of the month following the month the imbalance

occurred less any imbalance trades and specific payback volumes. The cashout

process will reduce the Shippers imbalance to be within the imbalance

tolerance upon payment or credit of the cashout amount.


(b) Shippers' imbalance that exceeds the imbalance tolerance

shall be cashed out at a price calculated by multiplying the portion that

exceeds the imbalance tolerance by the applicable rates as determined below.


(c) Determination of cashout price. Questar will use the "Inside

FERC Gas Market Report" first-of-the-month posting for Questar published for

the first of the month following final determination of the cashout volume to

set an index price. If "Inside FERC Gas Market Report" ceases publication or

to the extent prices are not reported
