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 Agreement, pursuant to the applicable terms of Section 47 of

the GENERAL TERMS AND CONDITIONS of this Tariff. If only FDD storage 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 storage capacity and the related storage gas, the acquiring

Shipper must take both the FDD storage capacity and the related storage gas. 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.


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.
