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.

 

Shipper shall specify any of the following designated storage points (hereinafter referred to

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