3. CONTRACT TOTAL QUANTITY:
The Contract Total Quantity (CTQ) shall be the maximum total volume of natural gas, specified
in the Shippers' PDD Service Agreement Appendices, that Northern may accept for service under
this Rate Schedule for injection or withdrawal to the Shipper's account. Shipper shall not be
permitted to exceed the CTQ. Shipper is to perform within the daily, monthly and inventory
parameters as outlined in Appendix A of the PDD Service Agreement.
The maximum and minimum rates for service under this Rate Schedule are listed on Sheet 55 of
this Tariff. Shipper shall pay the maximum rate for service under this Rate Schedule unless a
lower rate has been agreed to as set forth in Appendix A.
The rates and charges for service under this Rate Schedule shall include each of the following:
(a) Capacity Fee - The Capacity Fee set forth on Sheet No. 55 shall be multiplied by the
applicable CTQ. The Capacity Fee will be credited or refunded in proportion to the amount
of service that Northern is unable to provide the PDD Shipper.
(b) Injection Charge - The Injection Charge per MMBtu set forth on Sheet No. 55 shall apply to
all quantities received for Shipper's account.
(c) Withdrawal Charge - The Withdrawal Charge per MMBtu set forth on Sheet No. 55 shall apply
to all quantities delivered to Shipper.
(d) Monthly Inventory Charge - The Monthly Inventory Charge per MMBtu is set forth on Sheet
No. 55 and shall apply to the absolute value of the inventory balances in the Shipper's
PDD account for the month.
(e) Annual Rollover Charge - The annual rollover charge per MMBtu is set forth on Sheet No. 55
of this Tariff. Such charge shall apply to the balance held in Shipper's PDD Account as
of March 31st unless otherwise contractually authorized. Revenues received from the
annual rollover charge shall be credited in accordance with Section 57 of the GENERAL
TERMS AND CONDITIONS of this tariff.
(f) In no event will Northern charge a PDD shipper more than that which it would have charged
an FDD shipper using the same injection and withdrawal parameters over an FDD cycle year.
Discounted Rates: Northern may from time to time at its sole discretion charge any individual
Shipper under this Rate Schedule a PDD rate which is lower than the maximum rate set forth on
currently effective rate sheet, provided, however, that such rate charged may not be less than
the minimum rate set forth in currently effective Tariff rate sheet for Rate Schedule PDD.
Negotiated Rates: Northern and Shipper may mutually agree to rates for services that may be
above the maximum rates or below the minimum on the currently effective Rate Sheet for Rate
Schedule PDD. Such rates shall be subject to Northern's negotiated rate authority granted by
Transportation Service Associated with Deferred Delivery Service
PDD quantities must be delivered to or redelivered from a Deferred Delivery point pursuant to a
Throughput Service Agreement. Deliveries and redeliveries of the PDD quantities shall be
subject to the rates, terms and conditions of the applicable Throughput Service Agreement
including transportation entitlements and capacity allocations.
