GENERAL TERMS AND CONDITIONS

(Continued)

 

11. OPERATIONAL FLOW ORDERS

 

11.1. Circumstances Warranting Issuance - Transporter shall have the right to

issue Operational Flow Orders (“OFO”) as specified in this section that

require actions by Shippers in order (1) to alleviate conditions that

threaten or could threaten the safe operations or integrity of Transporter’s

system, (2) to maintain pipeline operations at the pressures required to

provide efficient and reliable firm transportation services, (3) to maintain

the system in balance for the foregoing purposes or for the purpose of

preventing undue imbalances with the downstream pipeline, and (4) at any

time downstream pipeline issues an OFO for its system. An OFO identical in

terms to that of the downstream pipeline shall be deemed to be issued

automatically by Transporter whenever the downstream pipeline issues an OFO

affecting deliveries from Transporter.

 

11.2. Applicability of OFO - To the extent practicable, based on Transporter’s

good faith judgment concerning the situations requiring remediation, an OFO

will be directed (1) first to Shippers causing the problem necessary in

which there is an operational problem, and (2) second to those Shippers

transporting Gas in the area of the system where action is required to

correct the problem necessitating the OFO. Transporter will notify affected

Shippers of termination of an OFO promptly after concluding that the OFO can

safely be removed.
