55.2 Reservation of Capacity for Expansion Projects (Continued)


(a) Seller may reserve capacity only for a future expansion project for which an

open season has been held or will be held within one year of the date Seller

posts such capacity as being reserved. If Seller elects to reserve capacity

for a future expansion project under this Section, such capacity may be

reserved for up to one year prior to Seller filing for certificate approval for

construction of the proposed expansion facilities, and thereafter until such

expansion is placed into service.


(b) Seller shall, on a limited-term basis up to the in-service date of the

expansion project, make available any capacity reserved under this section in

accordance with Section 49 of these General Terms and Conditions. A service

agreement for capacity available on such interim basis shall not be eligible

for a right of first refusal for purposes of Section 48 of these General Terms

and Conditions.


(c) Prior to reserving capacity for future expansion projects under this section,

such capacity shall first have been made available in accordance with Section

49 of these General Terms and Conditions.


(d) Subject to the foregoing, Seller may reserve capacity by means of a posting on

1Line which shall include, without limitation:


(i) A description of the expansion project for which the capacity will be



(ii) The total quantity of capacity to be reserved;


(iii) The location of the proposed reserved capacity on Seller's system;


(iv) When Seller held or anticipates holding an open season in connection

with the expansion project;


(v) The projected in-service date of the expansion project; and


(vi) On an ongoing basis, how much of the reserved capacity has been

subscribed on an interim basis.


(e) To the extent that capacity reserved pursuant to this Section 55.2 is not

sufficient to satisfy the requirements of an expansion project, Seller shall

conduct, no later than ninety (90) days after the close of an open season for

such expansion project, a reverse open season setting forth not unduly

discriminatory terms for the turn back of capacity. Capacity obtained through

a reverse open season shall be reserved for an expansion project pursuant to

the terms of this Section 55.2; provided, however, that the posting

requirements of Section 55.2(c) shall not apply to that capacity.


(f) Any capacity reserved for an expansion project that does not go forward for any

reason shall be reposted as available capacity within 30 days of the date the

capacity becomes available, except for capacity committed in service agreements

entered into on an interim limited term basis.
