Transportation Service Associated with Deferred Delivery Service

----------------------------------------------------------------

IDD quantities must be delivered to or redelivered from a Deferred Delivery Point

pursuant to a Throughput Service Agreement. Deliveries and redeliveries of the IDD

quantities shall be subject to the rates, terms and conditions of the upstream or

downstream Firm or Interruptible Throughput Service Agreement including transportation

entitlements and capacity allocations.

 

A transportation rate and fuel is charged both into and out of a Field Area storage

point. Except as provided below with regard to a transportation point and its

associated storage point, a transportation rate and fuel is charged for delivery to the

Ogden storage point. If redelivery from Ogden is to a Market Area point, there is no

additional transportation or fuel charge. If the redelivery is to a Field Area point,

the Field Area mileage/MID transportation rate and fuel is charged. To the extent a

volume is transported between a pooling point and its associated storage point, no

transportation fee or fuel shall be assessed. With the exception of Ogden, to the

extent a volume is transported from a storage point to a transportation point other

than its own associated transportation point then a transportation fee and fuel will be

assessed.

 

When the Ogden Deferred Delivery Point is used, the Shipper must use the same type of

service (i.e., firm or interruptible) to transport to and from the deferred delivery

point, unless agreed to otherwise by Northern on a non-discriminatory basis. However,

in the event Shipper has used interruptible service into the IDD account, Shipper may

utilize released capacity, under the terms and conditions of Section 47, Capacity

Release, to transport quantities from the IDD account.
