Capacity may be reserved for expansion projects only for a 12-month

period prior to Northern filing for certificate approval for

construction of proposed expansion facilities, and thereafter until

the effective date of any Service Agreement related to the certificate

filing or the date the expansion facilities are placed into service.


If Northern reserves capacity for an expansion project, it will notify

Shippers of its intent as part of Northern's posting of capacity on its

Internet website. Northern's posting for reserved capacity for future

expansion projects shall include the following information: (a) a

description of the project for which the capacity will be reserved;

(b) the total quantity of capacity to be reserved; (c) the location of

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

if so when, Northern 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. Northern will make reasonable efforts to update the

reservation posting up to the in-service date of the project to reflect

any material changes in the scope of the project. The reservation

posting or open season will include a non-binding solicitation for

turnback capacity from Northern's existing Shippers to serve the

expansion project. In the event Northern includes the solicitation for

turnback capacity in the reservation posting, the reservation of

capacity must be posted no later than 90 days following an open season

for a project.


Any capacity reserved under this section will be made available for

transportation service pursuant to Northern's GENERAL TERMS AND

CONDITIONS on a limited-term basis. Northern reserves the right to

limit any extension rights provided in the service agreement and

pursuant to Section 52 - Right of First Refusal of the GENERAL TERMS

AND CONDITIONS - commensurate with the effective date of any Service

Agreement supporting an expansion project or 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, with the

exception of capacity committed to in contracts entered into on an

interim limited term basis during the period the capacity was reserved.
