10.1 Imbalance Management and Operating Tolerances


(a) Imbalance. For purposes of this Section, "imbalance" shall

mean the cumulative difference between Receipt Quantities

less Fuel Reimbursement, and the quantities accepted by

Shipper or Shipper's designee at the Point(s) of Delivery,

resulting from current Month activity plus any beginning of

Month imbalance.


(b) Balancing Obligations. Daily and monthly balancing of Receipt

Quantities and the quantities Delivered to Shipper shall be

Shipper's responsibility. Transporter shall, to the extent

practicable, Deliver quantities for Shipper's account

concurrently with the receipt of Receipt Quantities. At no

time shall Transporter be required to receive quantities for

Shipper's account in excess of the quantities Shipper or

Shipper's designee will accept at the Point(s) of Delivery on

a concurrent basis. Similarly, Transporter shall not be

required to make quantities available for Delivery in excess

of the Receipt Quantities being Tendered by Shipper on a

concurrent basis.


(c) Operating Tolerances. Shipper and Transporter shall manage

the receipts and Deliveries so that the imbalance shall be

kept as near zero as practicable.


(d) Notification. Either Party shall notify the other as soon as

practicable when it becomes aware that receipts and

Deliveries are not in balance. Transporter shall formally

notify Shipper of allocated receipts, Deliveries, and related

imbalances, by way of Transporter's Electronic Bulletin

Board/Customer Information System as soon as allocated

quantities are available.


(e) Third Party Imbalance Management Services. Transporter shall

accommodate third-Party Imbalance Management Services on a

non-discriminatory basis as long as these services comply

with applicable GISB Standards and do not adversely impact

WIC's system operations. Criteria for third-Party services

will include compliance with GISB Nomination and Confirmation

Time Lines, and meeting Transporter credit requirements

appropriate for the quantity of Shipper Imbalance Gas for

which such Third Party may be responsible.
