GENERAL TERMS AND CONDITIONS

OPERATIONAL FLOW ORDERS

18. OPERATIONAL FLOW ORDERS

18.1 Operational Flow Orders.

A. Pipeline has established the operating terms and conditions related to operational

flow orders (OFOs) as set forth in this Section 18 in order to maintain system

reliability. If, Pipeline at any time determines that these OFO-related terms and

conditions are inadequate to ensure Pipeline's system integrity, Pipeline reserves the

right to file for and establish additional conditions under which Pipeline may issue

OFOs as Pipeline deems necessary to preserve its system reliability and maintain

service to its Customers.

B. Pipeline shall operate its system in a reasonable manner, based upon conditions known

to or forecast by Pipeline at the time, maintaining line pack, scheduling maintenance,

coordinating Receipts and Deliveries, and issuing OFOs as needed to maintain system

reliability and meet firm service obligations. Once an OFO has been issued, Pipeline

shall cooperate with the affected Customers to accomplish the results intended by the

OFO.

C. An OFO shall be an announcement by Pipeline that shall advise Customer of operating

conditions that affect its services or direct a Customer or class of Customers to take

specific action. Each OFO shall contain the following information:

1. time and date of issuance;

2. time that OFO is effective;

3. duration of OFO (if none is specified, the OFO will remain effective until

further notice);

4. the Customer(s) or class of Customers affected by the OFO;

5. the action, if any, that Customer(s) must take; and

6. any other information required by the terms of this Tariff.

D. How Pipeline May Issue OFOs.

1. Pipeline shall issue an OFO by posting a notice of the OFO on the Website and by

e-mailing the flow order to all affected Customers that have provided Pipeline

with an e-mail address. Customer shall monitor the Website for any OFO applicable

to Customer's service and shall be solely responsible for compliance with each

OFO.

2. When the OFO is applicable on a Customer-specific basis or otherwise directly

affects such Customer, Pipeline shall directly communicate the OFO to one of

Customer's designated contact person(s) via e-mail unless Pipeline and Customer

have agreed upon other commercially reasonable means of communication. Each firm

Customer shall provide Pipeline with the name, e-mail address, facsimile number,

and telephone number of at least one designated contact person available on a

twenty-four hour basis and it shall be Customer's responsibility to keep this

information current.
