GENERAL TERMS AND CONDITIONS

WEBSITE

16.4 System Alerts. Pipeline may issue a "System Alert" to notify Customers of operating

conditions on its system, changes in operating conditions, and other system developments

that may affect scheduling. A System Alert is an informal notice of possible future

conditions or developing conditions on the system: by itself, a System Alert does not

change any Customer's penalty position. To the extent that reliable information relevant

to possible issuance of an operational flow order (OFO) or other status of the system is

available, Pipeline shall publish it on the Website. If a System Alert indicates that an

OFO may be imminent, Pipeline shall advise its Customers what action is requested and what

future actions may be mandated if voluntary steps are not taken. Under such circumstances,

Customers are asked to comply as quickly as possible with the System Alert, to reduce the

need for future action by Pipeline. Customers should be prepared to act on short notice.

System Alerts may be directed to all Customers, or to specific Customers on a not unduly

discriminatory basis. By issuing a System Alert, Pipeline shall not be precluded from

issuing an OFO, if circumstances ultimately require. The System Alert is intended to give

Customers the opportunity for voluntary compliance, rather than requiring mandatory action

under the OFO provisions of this Tariff.
