26.5 Reservation of Capacity for Company's Expansion/Extension

Projects (Continued)

reserved capacity on the pipeline system; (d) whether, and

if so when, Company anticipates that an open season for the

capacity will be held or the reserved capacity will

otherwise be posted for bids; (e) the projected in-service

date of new facilities; and (f) on an ongoing basis, how

much of the reserved capacity has been sold on a limited-

term basis that would otherwise be eligible for a right of

first refusal. Company will make reasonable efforts to

update the reservation posting up to the in-service date of

Subsection 26.2(a) above, remains unsubscribed after the

posting for bid, and if such unsubscribed capacity is

insufficient to serve the expansion/extension project, the

reservation posting or open season will include a non-

binding solicitation for turnback capacity from Company's

existing Shippers to serve the expansion/extension project.

Company shall post a non-binding solicitation for expansion

project related turnback capacity no later than 90 days

after the close of an expansion project's open season that

is posted in accordance with Subsection 26.1, specifying

the minimum terms for a response to the solicitation.

Any capacity reserved under this Subsection will be

made available for transportation service pursuant to

Company's FERC Gas Tariff on a limited-term basis up to the

in-service date of the expansion/extension project. Company

reserves the right to limit any extension rights provided in

such Service Agreement(s), pursuant to Section 5 - Right of

First Refusal of Rate Schedule T-1 - commensurate with the

proposed in-service date of any facilities. Any capacity

reserved for a project that does not go forward for any

reason shall be reposted as generally available within

30 days of the date the capacity becomes available. The

previously reserved capacity will become available when the

Company posts the capacity on its Informational Postings

web site under Subsection 26.2(a).
