GENERAL TERMS AND CONDITIONS

(Continued)

 

11.2 Critical Operating Procedures

 

(a) Strained Operating Condition may be issued using the

notification procedures of Section 6.1(e)(iv)(2) of this Tariff

in situations where in Transporter's judgment general system

flexibility, normally available Day to Day, cannot be afforded

to Shippers to accommodate minor variations in receipt and

Delivery quantities from Nominated levels. Examples of such

operating conditions include (1) situations when the maximum

storage withdrawal capacity is being utilized and allocated

Receipt Quantities are less than Delivery Quantities; (2) when

the maximum storage injection capacity is being utilized and

allocated Receipt Quantities are greater than Delivery

Quantities; and (3) when actual Receipt and Delivery Quantities

on a segment of the transmission system vary from Nominations

such that Transporter's capability to receive and Deliver Gas

for its Shippers is adversely affected. The issuance of a

strained operating condition requests Shippers voluntary

support in correcting their situations and does not cause the

Unauthorized Overrun Rates to increase.

 

(b) If the Strained Operating Condition does not improve, a

Critical Condition may be imposed after the Strained Operating

Condition has been in effect for at least two Intraday

scheduling cycles. The Critical Condition will be issued using

the notification procedures of Section 6.1(e)(iv)(2) of this

Tariff. The Critical Condition will be limited to the smallest

area of the system possible so that the fewest number of

Shippers are affected. The higher Unauthorized Overrun charges

provided for in the applicable Statement of Rates will be in

effect during the Critical Condition.

 

(c) Transporter's Operational Flow Orders, critical periods and

critical notices, when issued, shall specify the conditions

underlying such issuance and shall describe the specific

responses required from the affected Parties (NAESB Standard

1.3.26).
