11.8 OPERATIONAL BALANCING AGREEMENTS ("OBA")

(a) For the purpose of minimizing operational conflicts

between various pipeline facilities with respect to

the delivery of Gas to and from Pipeline's facilities,

Pipeline may enter into Operational Balancing

Agreements (OBAs) with appropriate parties that

operate natural gas facilities which interconnect with

Pipeline's system (herein called "OBA Party"). Such

OBA shall specify the Gas Custody transfer procedures

to be followed by Pipeline and OBA Party for the

confirmation of scheduled quantities of Gas to be

received by Pipeline at the Point of Receipt or

delivered by Pipeline at the Point of Delivery. Such

OBA will provide that any variance between actual

quantities and scheduled and confirmed quantities at

the point where the OBA is in place for any Gas Day

shall be cashed out or resolved in-kind promptly

pursuant to the terms of the OBA and that such daily

scheduling and monthly balancing variances are the

responsibility of the OBA Party.

To facilitate such determination of variances on a

timely basis, Pipeline and the OBA Party will agree in

the OBA on necessary measurement and accounting

procedures. Pipeline shall post on the LINK® System

those Points of Receipt and Points of Delivery at

which an OBA is in effect.
