(a) Strained Operating Condition (Continued)

(ii) Without limitation of Transporter's exercise of its

reasonable judgment to determine whether and the extent to

which it will issue an SOC at any time, Transporter will

either declare an SOC under the following circumstances or,

if in the exercise of Transporter's reasonable judgment it

does not declare an SOC under any of these circumstances,

Transporter shall explain its reasons for not issuing an SOC

by EBB posting within the next Business Day.

(A) when the average of six consecutive hours of the Gas Day

for total system linepack falls below 7000 MMcf and

Washington Ranch is on maximum (operationally) available

withdrawal;

(B) when the average of six consecutive hours of the Gas Day

for total system linepack exceeds 7900 MMcf and

Washington Ranch is on maximum (operationally) available

injection.

(iii) An SOC will be declared for a specific Shipper(s) and/or a

specific location(s) if they can be identified, and a

specific direction (i.e., Pack or Draft). If a specific

shipper or location SOC is not appropriate, the SOC will be

declared for the North System, the South System, or the

entire system. Such notice will be provided using the

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

(iv) Notification of an SOC declaration shall include

identification of linepack status and whether the SOC is a

Pack SOC or a Draft SOC.

(A) A "Pack" designation shall be applied to flow variances

that exacerbate a high linepack condition (e.g.

undertakes from Transporter at a Delivery Point(s)). A

"Draft" designation shall be applied to flow variances

that exacerbate a low linepack condition (e.g.

overtakes from Transporter at a Delivery Point(s)).

(B) A "Pack" designation shall be applied to flow variances

that exacerbate a high linepack condition (e.g.

overdelivery into Transporter at a Receipt Point(s)).

A "Draft" designation shall be applied to flow

variances that exacerbate a low linepack condition

(e.g. underdelivery into Transporter at a Receipt

Point(s)).
