affected by the Trade).


(vi) Transporter shall permit Trade arrangements at no

additional cost to the Shippers.


(vii) After completion of all Trade transactions, Transporter

quantities first. Trade quantities shall be applied to

Agreement-level imbalances until the Trade quantities

have been fully allocated.


(f) A Shipper may only apply one of the adjustment procedures to

any individual unit of imbalance (i.e., the same quantity

cannot be scheduled for Trade and imbalance payback, however,

portions of an imbalance may be scheduled for different

adjustment procedures).
