6.3 Adjustments to Confirmations due to Supply Underperformance


(a) If, on any Day, Transporter determines in its reasonable

discretion that underdelivery of Natural Gas into

Transporter's system (supply underperformance), if allowed to

continue, could adversely affect system integrity,

Transporter shall have the right, after providing as much

advance notice as possible, to make adjustments at such point

to Operators' confirmations to reflect more accurately such

Operators' previous actual deliveries of supply into

Transporter's system. The provisions of this Section 6.3

shall apply either until the underdelivery is eliminated or

until this threat to system integrity no longer exists.


(b) Transporter shall identify potential threats to system

integrity by utilizing criteria such as: weather forecast for

the market area and producing area; system conditions,

including outages, maintenance, equipment availability and

linepack; overall projected pressures at various locations

and meters; and storage conditions.


(c) When supply underperformance occurs and the deficient source

of supply is immediately identifiable, Transporter shall make

adjustments to that Operator's confirmed quantities. Those

supplies that are independently verifiable by Transporter and

which match the Operator's confirmation shall not be subject

to the provisions of this Section 6.3. When the deficient

source of supply is not immediately identifiable, the

smallest affected area shall be identified and these

procedures apply only to that portion of the system.


The following procedures shall be used to adjust Operators'

confirmed quantities of Natural Gas in the event of supply
