GENERAL TERMS AND CONDITIONS

24 CAPACITY POSTING AND CONTRACT PROCEDURES

24.1 Applicability

This section shall apply to the process of posting and contracting for capacity on existing

facilities other than capacity which is available under the ROFR process or through the

capacity release program, or as part of an expansion project.

24.2 Posting

Transporter shall maintain and update postings of unsubscribed capacity, operationally

available capacity, and design capacity, in accordance with 18 CFR 284.13 and in the format

set forth in NAESB standard 4.3.23.

24.3 Contracting for Available Capacity

Except as otherwise provided in Section 24.4 and Section 24.5 herein, Transporter will

award offers for posted capacity (including requests to change primary receipts or primary

delivery points) on a first-come, first-served basis and in accordance with the currently

effective rate schedules of this tariff. Posted capacity will be awarded on a first-come,

first-served basis to any Shipper willing to pay the applicable maximum tariff rate, and a

Shipper need not offer to pay a different rate (including, without limitation, a negotiated

rate) that may be in excess of the maximum tariff rate to obtain such capacity. Nothing

herein requires Transporter to accept requests to change primary receipt or delivery points

or accept offers for available capacity at less than maximum tariff rates; provided

however, that Transporter will treat all requests or offers on a nondiscriminatory basis.

The unsubscribed capacity postings set forth in 24.2 above will be updated at each

nomination cycle to reflect any capacity that has been awarded.
