GENERAL TERMS AND CONDITIONS (Cont'd)
17.2 Pipeline-Specific Operational Standards for Issuance of OFOs.
(a) If, in Transporter's judgment, impending operating conditions will cause the delivery pressure to
one or more Shippers to drop below the pressure provided in the Service Agreement(s) of the Shipper(s),
Transporter may immediately issue an Operational Flow Order pursuant to this Section requiring that deliveries
under all of Transporter's Rate Schedules be made on a basis consistent with the flow rates and limitations
set forth in the Operational Flow Order. If only one segment of Transporter's system will be affected by low
pressure, the Operational Flow Order shall be limited to that segment of the system and shall be so stated.
For the duration of this Operational Flow Order, increases in scheduled delivery quantities within affected
segments of Transporter's system will be made on a prospective basis only.
(b) Transporter shall have the right to issue Operational Flow Orders requiring Shippers to deliver
gas to Transporter at Shipper's primary receipt points under Shipper's FTS, NTS, NTS-S, TPS, or GTS Service
Agreement with Transporter. This right shall also apply to Shippers which have acquired capacity via
Transporter's capacity release and assignment procedures.
(c) Proper utilization of Transporter's storage facilities is crucial to Transporter's ability to
provide firm services to Shippers. Therefore, in the event Transporter determines that action is necessary to
prevent damage to the integrity of its storage fields or to ensure the operating performance of Transporter's
system, including its storage fields, Transporter may issue an Operational Flow Order as follows to preserve
its ability to provide firm service to Shippers:
(1) Transporter may issue an Operational Flow Order limiting all Shippers to receipts and
deliveries at primary points.
(2) Transporter may issue an Operational Flow Order requiring each Shipper at a given
receipt point to fully utilize all of its non-storage receipt point firm transportation capacity on
Transporter prior to being entitled to withdraw quantities from storage.
(3) Transporter may issue an Operational Flow Order limiting or prohibiting transfers of
injection rights, withdrawal rights, or storage inventory by Shipper where:
(i) Transporter's storage pool deliverabilities, in the aggregate or in any
segment, have declined to such a level that, in Transporter's discretion, a transfer may
jeopardize Transporter's ability to perform firm service to any Shipper; or
(ii) The transfer could cause Transporter to issue an Operational Flow Order under
another part of this section.
(4) Transporter may issue an Operational Flow Order directing a Shipper to correct
imbalances or operate within the limitations on transportation, storage, injections or withdrawals as
set forth in the Shipper's Service Agreement or the applicable Rate Schedule.
(d) In addition to the other provisions of this Section 17 that may be applicable to Shippers under
the NTS and NTS-S Rate Schedules, Transporter may issue an Operational Flow Order to a Shipper under the NTS
and NTS-S Rate Schedules to require Shipper to replenish its Gas Supply Quantity (GSQ) earlier than required
by NTS and NTS-S Rate Schedules Section 2(f) in order for Transporter to provide no-notice service, replace
borrowed gas or to preserve system integrity.
(e) Transporter may, on a nondiscriminatory basis, issue such other reasonable Operational Flow
Orders as may be required for the purposes set forth in this Section in order to provide the services
contemplated by this Tariff. For example, but without limitation, Transporter may issue an OFO directing a
Shipper to take certain actions to enable Transporter to adequately respond to the following type of exigent
circumstances occurring on Transporter's system:
(1) Freezing of wells or pipelines or other essential equipment to the extent that such
freezing damages or destroys or otherwise impairs Transporter's essential facilities or Transporter's
ability to monitor and control Transporter's essential facilities or results in the loss of supplies of
natural gas from upstream transporters, Transporter's storage fields, or producers of natural gas.
