F. Third Party Storage Shipper(s). To the extent the volumes of natural gas to

be transported for the Shipper have previously been transported under one

of Northern's rate schedules to be delivered to a customer-owned or

third-party leased storage facility, such volumes will be transported from

the storage facility location to the Shipper's market area delivery point

and will be charged the Field/Market TF, TFX or LFT reservation fee, if

applicable, and the appropriate commodity rate as set forth in this Tariff.


G. Other Flowing Gas Allocations. Unless otherwise specifically provided for

within these GENERAL TERMS AND CONDITIONS, and except at points that have

an Operational Balancing Agreement (OBA) in effect, a pre-determined

allocation (PDA) methodology of ranked, pro rata, percentage, swing or

operator provided value will be agreed upon at the point. The upstream and

downstream operators will provide the PDA methodology and contract

rankings, if applicable, to the allocating party and/or the party

performing the measurement function after or during confirmation and before

the close of business of the production month. If the parties have not

agreed upon a PDA methodology, or if a point is not covered by the last-

through-the-meter methodology, as described above, and there is a dispute,

then pro rata based upon confirmed nominations will be used as the default

methodology. The party responsible for custody transfer (the party

performing the measurement function) will provide the allocation.
