11.1Strained and Critial Operating Condition Procedures (Continued)

(a) Strained Operating Condition (Continued)

(x) During an SOC, Shippers in an SOC area will have a catch-up

nomination opportunity to resolve daily imbalances prior to

the assessment of an SOC Daily Imbalance Charge. For each Gas

Day ("Day 1") during which an SOC is in effect, Shippers in

the SOC area will have the subsequent Gas Day ("Day 2") to

reduce the previous Gas Day's daily imbalance to within the

stated threshold level. For this nomination opportunity to

reduce the otherwise applicable penalty, a Shipper's scheduled

quantities, excluding the catch-up nomination(s) in the SOC

area, may not cause a subsequent Day daily imbalance that is

worse on a percentage basis, in the same direction, than its

daily imbalance on the first Day of the SOC event.

(A) Catch-up Nominations: Delivery Points

1. Shippers must submit a separately identified

nomination to catch-up the Day 1 daily imbalance.

2. Such nomination must be to the same Delivery Point

as the original nomination.

3. Such nomination will not be considered when

evaluating a constraint at a Delivery Point.

4. System constraints or supply failures will not

excuse Shipper's requirement to balance within the

Day 1 threshold level on Day 2.

5. Any of a Shipper's Rate Schedule FT-1, FT-2, FTH-

V, FT-H, NNTD, NNTH and/or IT-1 TSAs may be used

to submit a catch-up nomination.
