11.1Strained and Critial Operating Condition Procedures (Continued)

(a) Strained Operating Condition (Continued)


(v) When conditions threaten the operational integrity of the

system, Transporter shall use reasonable efforts to resolve

the situation causing the operational distress prior to

declaring an SOC. Depending on the circumstances, Transporter

may use any one or more of the following operational remedies:


(A) attempting to contact customers that are currently out

of daily balance to coordinate adjustments to their

scheduled quantities and actual flows;

(B) injecting or withdrawing from Washington Ranch, as

permitted by operational limitations, to bring linepack

into acceptable levels; and/or

(C) operationally offsetting, to the extent possible, packs

and drafts on the critical areas of Transporter's system

to minimize impact on customers.


(vi) Transporter must declare an SOC before 12:00 p.m. (Mountain

Clock Time) for such SOC to apply to the current Gas Day.

Should Transporter declare an SOC after 12:00 p.m. (Mountain

Clock Time), such SOC shall apply to the next Gas Day.


(vii) An SOC will remain in effect until Transporter, in its

reasonable judgment, determines that such operating conditions

no longer exist and notifies its Shippers that it is lifting

the SOC or that a Critical Operating Condition has been

declared. Such notice will be provided using the notification

procedures of Section 6.1(a)(xii) of the GT&C.


(viii)When an SOC is in effect, Shipper(s) or Operator(s) in the SOC

area are required to reduce daily imbalances at each scheduled

Receipt Point or Delivery Point to the threshold level

designated in Transporter's Notice of SOC. The threshold

level will be determined solely by the operational judgment of

Transporter based on the severity of the conditions

necessitating the SOC.

(A) SOC Threshold

1. The SOC threshold can range from 4% to 10% of

scheduled quantities at the scheduled Delivery

Point or 2,000 dth, whichever is greater.


2. The SOC threshold can range from 4% to 10% of

scheduled quantities at the scheduled Receipt

Point or 2,000 dth, whichever is greater.
