(a) Types of Operational Flow Orders

(1) Emergency System Maintenance - Pipeline may direct

Customers under any firm or interruptible Rate

Schedule to increase or decrease receipts of flowing

gas on a particular portion of the system in order to

accommodate required unscheduled maintenance.


(2) Extreme Conditions - For purpose of this Section

5.9(a)(2), an extreme condition exists on any portion

of Pipeline's system when throughput approaches

capacity, when weather conditions so require, or when

operating pressures on the affected portion are

significantly less than or greater than normal system

operating pressures despite Pipeline's effort to

maintain normal pressures, and further decline or

increase in operating pressures would impair

Pipeline's ability to receive or deliver quantities

of gas in accordance with its service obligations.

Pipeline may declare an extreme condition situation

for the affected portion of the system by notifying

the meter operator(s) and Customer(s) through its EBB

and/or IWWW and by telephone and/or facsimile

communication. Once declared, Pipeline will post

notification of the extreme condition on its EBB

and/or IWWW at the commencement of each Day until

Pipeline notifies the meter operator(s) and the

Customer(s) through the EBB and/or IWWW and telephone

and/or facsimile communication that the extreme

condition has ended. When an extreme condition is

declared to become effective at any time other then

the commencement of any Day, Customer(s) will use

their best efforts to bring deliveries to nominated

levels as soon as possible but in no event later then

two (2) hours, after which the Daily Scheduling Charge

provided for in Section 5.9(b)shall apply to variances

in excess of the 3% tolerance level.


(b) Daily Scheduling Charge - When Pipeline declares a System

Maintenance OFO as to any portion of its system, or if

necessary the entire system, the daily scheduling tolerance

level shall be 5% of the authorized delivery levels.

However, when Pipeline declares an Extreme Condition OFO as

to any portion of its system, the daily scheduling tolerance

level shall be 3% of the authorized delivery levels. The

Charge for variances beyond the tolerances levels as stated

in the OFO shall be:


(i) the greater of $5 or two times the Cash Out price as

defined in Paragraph 14.7(c) for each Dth which

exceeds authorized delivery levels by more
