4. CAPACITY RELEASE

4.1 (a) This section sets forth a capacity release program under

which a Releasing Customer can release all or part of its

firm capacity back to Pipeline for assignment to a Potential

Customer or a Prearranged Customer that is seeking the

capacity of the Releasing Customer by entering into a

Service Agreement with Pipeline. Pipeline will permit

segmentation of capacity right held by Customer(s) including

Replacement Customer(s), to the maximum extent it is

operationally feasible. Provided, however, that a Releasing

Customer shall not be permitted to release capacity until

the Potential Customer or a Prearranged Customer enters into

a Service Agreement with Pipeline for such released

capacity. Provided, further, that the above requirement for

contracting shall not inhibit the ability of the Replacement

Customer to submit a nomination at the next available

opportunity after the Pipeline is notified of the release.

GISB Standard(s) 5.3.5, 5.3.8, and 5.3.30 are incorporated

herein by reference.

(b) A Releasing Customer may release capacity held pursuant to

18 C.F.R. Subparts B or G of Part 284 of the Commissions's

regulations. A Releasing Customer which receives service

under a firm Rate Schedule under this FERC Gas Tariff is

permitted to release its capacity in whole or in part,

including any segments of its capacity, and on a permanent

or temporary basis. When a Releasing Customers assigns its

service rights by segments and/or assigns only a portion of

its MDQ under that agreement, the Releasing Customer's

Service Agreement shall be deemed to be modified in

accordance with the assignment and the Releasing Customer

will be able to utilize only the unassigned service rights

during the term of the release.
