C. Capacity Release
----------------
An FDD Shipper may utilize Northern's capacity release mechanism to permanently or
temporarily release all or a portion of its FDD capacity for any or all of the periods for
the remaining term of the FDD Service Agreement, pursuant to the applicable terms of Section 47
of the GENERAL TERMS AND CONDITIONS of this Tariff. If only FDD capacity is to be released,
then the release can be only on the same period basis. If the releasing Shipper wishes to
release both FDD capacity and the related storage gas, the acquiring Shipper must take both the
FDD capacity and the related storage gas. The gas held in the releasing Shipper's storage
account cannot exceed the available FDD capacity after the release. Further, in no way shall
releases or recalls and reputs of FDD capacity result in the related gas in the storage account
being stranded from the related FDD capacity. If the releasing Shipper recalls/reputs its FDD
capacity, the related storage gas must be proportionally recalled/reput unless otherwise agreed
upon by Northern. If any storage gas balance remains in the storage account at the time the
capacity release terminates, the storage gas shall be returned to the releasing Shipper. The
release may be effectuated at any time during the periods, subject to the released FDD capacity
continuing to be used according to the terms for the assigned FDD capacity. Further, Northern
will work with the parties to assure that gas is not stranded in a Shipper's storage account.
Northern shall not be liable for the related gas held in the acquiring Shipper's storage
account.
D. Injection Period
----------------
Shipper shall be entitled to nominate a quantity of natural gas for injection up to its FDQ at
an available designated storage point during the Injection Period as specified in Shipper's FDD
Service Agreement. Upon acceptance of such nomination by Northern, Shipper shall deliver to
Northern quantities scheduled for FDD service. However, Northern may refuse to schedule any
nomination which would cause the Shipper's FDD Account Balance to exceed its FDD quantities as
specified in the FDD Service Agreement.

as storage point) as its injection and withdrawal storage point:
