GENERAL TERMS AND CONDITIONS

9. SYSTEM MANAGEMENT (Continued)

 

The Operational Flow Order shall identify with specificity the type of

Operational Flow Order which is being issued (Standard or Emergency

Response), the operational problem to be addressed, the action(s)

Customers must take, the time by which Customers must take the specified

action(s), the period during which the order will be in effect, and the

conditions which will cause the Operational Flow Order to end. To the

extent that the effective period of the OFO is dependent on operational

variables, MRT will post information about the status of such variables

during the effective period of such OFO, as soon as practicable after,

and to the extent that, such information becomes available to MRT. MRT

will provide as much advance notice to affected Customers as is

operationally feasible before issuing an Operational Flow Order. When

MRT issues an Operational Flow Order with less than twenty-hour

notification, it will send to the Commission a detailed explanation of

all relevant information specific to that individual situation to

justify the issuance of the Operational Flow Order. To the extent

operationally feasible, MRT will post System Protection Warnings on its

Internet web site to advise Customers of the possibility of conditions

that may lead to an OFO and/or that an OFO may be issued. Any such

posting shall constitute prior notice that an OFO may be imminent.

 

(b) Consistent with the provisions in Section 9.7(a) above, MRT

will issue two types of Operational Flow Orders:

 

(i) Standard Operational Flow Orders are defined as pre-

emptive or preventive actions or measures that neutralize or

reduce threats to, or otherwise preserve, as determined by MRT in

its sole discretion, the integrity of all or a portion of its

system; and

 

(ii) Emergency Response Operational Flow Orders are defined

as actions or measures required by MRT that neutralize or reduce

threats to, or otherwise preserve, the integrity of all or a

portion of its system which requires immediate response as

determined by MRT in its sole discretion.

 

(c) An Operational Flow Order may require a Customer to take any

of the following actions, or similar actions:

 

(i) In the case of a storage Customer, to inject gas into

or withdraw gas from storage in accordance with a schedule

ordered by MRT. Injections or withdrawals may be required at any

time during the year.
