(3) Operational Impact Area


For purposes of this Section 5, two or more

Transportation Service Agreements shall be deemed to be

within the same Operational Impact Area only if the Gas

transported under the Transportation Service Agreements

during the Month was from: (1) Field Zone to Field

Zone; (2) Field Zone to Zone 1A; (3) Field Zone to Zone

1B; (4) Field Zone to Zone 2; (5) Zone 1A to Zone 1A;

(6) Zone 1A to Zone 1B; (7) Zone 1A to Zone 2; (8) Zone

1B to Zone 1B; (9) Zone 1B to Zone 2; or (10) Zone 2 to

Zone 2. Under a Transportation Service Agreement where

Gas is received in different Zones during the Month or

Gas is delivered in different Zones, the Zone to Zone

comparison shall be established using a weighted average

of receipts and deliveries in the Zones.


Nothing contained in this Section 5.2(B) shall require

Trunkline to incur a financial loss as a result of netting

and trading excess receipts and excess deliveries or to

continue such netting and trading if doing so would be

inconsistent with the prudent operation of Trunkline's

pipeline system.

shall be the absolute value of the contract imbalance after

minimizing the imbalance in accordance with Section 5.2(B)

herein divided by actual monthly deliveries. The imbalance

level for a TABS-1 Party or an OBA Party shall be the

absolute value of the monthly contract imbalance divided by

actual monthly deliveries.


(D) Imbalance Due Trunkline


For contract imbalances, after minimization in accordance

with Section 5.2(B) herein, where actual deliveries exceed

actual receipts, less Fuel Reimbursement, Shipper or

party shall pay Trunkline based on the accumulated sum of the

results of the formulas listed below:
