GENERAL TERMS AND CONDITIONS

 

day of the current month to remedy any imbalance exceeding the imbalance

tolerance. To remedy an imbalance, Shippers will have the ability to trade

imbalances pursuant to § 15.4 or pay back the imbalance in the current month

pursuant to § 15.5.

 

(iii) At the end of the month in which the imbalance for the

prior month was posted and after all imbalance trades and pay back have been

entered, Shipper will be cashed out, pursuant to § 15.6, for any remaining

imbalance that exceeds the imbalance tolerance.

 

15.4 Imbalance Trading.

 

(a) Shipper will be able to trade imbalances with other Shippers

that have an imbalance that will reduce each Shipper's imbalance.

 

(b) All imbalance trading must be conducted through Questline.

If Shipper desires to trade imbalances on Questline, Shipper must consent to

Southern Trails releasing to others, on Questline, Shipper's monthly imbalance

information.

 

(c) Once Shippers have agreed to trade their imbalances, each

Shipper must notify Southern Trails by completing an imbalance trading notice

on Questline. This notice to Southern Trails will be deemed to be the

Shipper's direction to Southern Trails to make the imbalance trade on the

Shipper's account. If the Shipper's notices coincide, Southern Trails will

adjust Shipper's accounts to reflect the imbalance trade.

 

(d) Shippers are responsible for making whatever arrangements

they deem necessary to finalize and document the imbalance trade among

themselves.

 

(e) Southern Trails shall not be liable for any losses incurred

by a Shipper if a Shipper is unable to complete an imbalance trade once

Shipper has notified Southern Trails of the imbalance trade.

 

15.5 Imbalance Payback Option. Subject to available transportation

capacity, operational constraints and approval by Southern Trails during the

remainder of the month after notification of its monthly imbalance, a Shipper

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.
