9. SYSTEM MANAGEMENT (Continued)

 

9.5 If, in MRT's sole discretion, it is necessary or desirable in

order to preserve the overall operational integrity of MRT's system, MRT may

issue:

 

(a) Operational Flow Orders, or

 

(b) System Protection Warnings.

 

9.6 MRT will post Operational Flow Orders and System Protection

Warnings on its Internet web site or provide notice to its Customers by any

other reasonable means.

 

9.7 Operational Flow Orders

 

(a) An Operational Flow Order may be noticed if MRT determines that

(i) pressures in its pipeline, system, or in a portion or portions thereof,

threaten to move, or have moved, beyond the normal minimum or maximum

operating ranges for such system or portion(s); (ii) actual storage activity,

on a cumulative basis, threatens to move, or has moved, beyond cumulative

daily scheduled injections and/or withdrawals of its firm Customers; (iii)

system receipts and/or deliveries threaten to move, or have moved, into a

range which would impinge upon line pack and storage capacity determined by

MRT as prudently required to be retained for operations and flexibility to

meet changing conditions; (iv) safe and efficient operation of MRT's system,

or segments thereof, consistent with applicable laws, regulations, orders and

standard industry operating practices is threatened; (v) operational action is

required due to the occurrence of an event of force majeure or in order to

maintain or repair physical facilities; or (vi) for any other reason,

including operating conditions, weather and actions of any Customers contrary

to rights and obligations under this tariff, MRT's projected system

deliverability or operational integrity, including the ability to provide any

Customer its firm service entitlement, is threatened or compromised. The

operational conditions that would cause MRT to issue a System Protection

Warning and/or Operational Flow Order shall be posted, and quantified, to the

extent practicable, on MRT's Internet web site and updated from time to time,

as necessary.
