both the Shipper's primary receipt point(s) south of the MID 7B Segmentation Point

and the primary delivery point(s) north of the MID 7B Segmentation Point will be

available to the Shipper in both the south and north segments, respectively.

Shipper nominations that are at or below the MDQ in the segment will be scheduled on

a primary or alternate basis. Shipper nominations that exceed the MDQ in the

segment will be scheduled on an interruptible basis. Furthermore, nominations

within the segment that are scheduled on an alternate basis will be designated as

Alternate 1 (for nominations within the path) or Alternate 2 (for nominations

outside the path).


d. To the extent it is operationally feasible and subject to subpart 2(d), a segmented

transaction consisting of a backhaul and a forwardhaul nominated to the same point

forwardhaul and backhaul delivered to the same point can exceed the MDQ of the

original agreement.


e. All original contract provisions regarding rates apply to the segmented contracts.

The reservation charge will be billed on the contract(s) as agreed to by Northern

and the Shipper. The commodity rates and fuel use and unaccounted for will be

billed on the contracts that have been nominated during the month.
