2. APPLICABILITY AND CHARACTER OF SERVICE (Cont'd.)

2.10 Transporter may reject nominations, require revised nomina-

tions, issue operational flow orders or take such other action

as is reasonably required to:

(a) protect any of Transporter's facilities from excessive

pressure or other similar threats to the integrity of its

system, and

(b) permit Transporter to inject or withdraw gas from individual

storage fields in a manner consistent with the performance

characteristics of such fields.

Transporter shall, as soon as is reasonably practicable, notify

the Commission and post on its Web Site the circumstances and

justifications for any actions taken pursuant to this Subsection

2.10.

2.11 Notwithstanding Section 13 of the General Terms and

Conditions, an FST Shipper may change its nomination effective

on any hour of the day to reflect changes in quantities to be

delivered or received under its transportation contract(s)

with pipelines that are physically interconnected with

Transporter which are associated with service at FST receipt

or delivery points, by notifying Transporter and the

interconnecting transporter one hour in advance.

Nominations changed pursuant to this Section 2.11 shall be

accepted by Transporter only to the extent that Transporter's

scheduling of such change will not reduce the scheduled quantities

of another firm shipper.
