Firm Throughput Services


(i) PowerPak Option



Shipper may elect to include a PowerPak Option with a service agreement

under this Rate Schedule and service under one of Shipper's Deferred

Delivery Service Agreements. Each service shall be separately

contracted, nominated, scheduled and/or curtailed in accordance with the

GENERAL TERMS AND CONDITIONS of this tariff. The PowerPak option can

only be at points with EFM with real time communication for the location.

The PowerPak Option shall apply to all volumes under the applicable

service agreements or transaction. The maximum rate shall be the maximum

TF rate plus the maximum rate for the applicable Deferred Delivery

Service. A Shipper will be charged separately stated transportation and

deferred delivery rates. Northern and Shipper will agree to the specific

volumetric parameters (such as maximum injections, withdrawals, and

inventory limitation) as set forth in the applicable deferred delivery

service agreement or transaction. Shipper must execute a PowerPak

addendum (as set forth on Sheet 432 herein as may be revised from time to

time) to its throughput service agreement. To the extent Northern and

Shipper have agreed to a discounted rate and Shipper fails to deliver or

receive volumes in accordance with the parameters, which shall be set

forth in the related service agreements or transaction, the rate shall be

the maximum rate applicable to both rate schedules. Northern, on behalf

of shipper, will schedule volumes to and from the storage account to

minimize imbalances and delivery point variances. This reconciliation

shall take place daily during the last nomination cycle of the gas day.

This reconciliation will be based on the information available to

Northern. Northern will not be responsible for any remaining imbalances

or scheduling variances ultimately charged. Shipper shall resolve any

remaining imbalances in accordance with the tariff and shall pay any

applicable DDVC charges.


(j) Other



Any additional costs which may be properly billed in accordance with the

provisions of this Rate Schedule and the GENERAL TERMS AND CONDITIONS.
