3.2 (Continued)

(b) Pursuant to Section 3.2(e) of this Rate Schedule, when

delivered quantities exceed scheduled quantities (draft) at a

primary delivery point, such variance shall be deemed "no-

notice draft quantities" and shall not exceed the lower of: 1)

10% of Shipper's MDQ, or 2) the difference between the

Shipper's MDQ and the scheduled quantity. Any quantities in

excess of the no-notice draft quantities will be an imbalance

on Shipper's TSA and subject to Section 10 of the GT&C.

points listed in Exhibit A of Shipper's NNTH TSA will be

netted together and the net pack added to, or the net draft

subtracted from, the no-notice account balance as long as such

netting does not serve to effectuate transportation across

persistent system constraints.

(d) In the event a pack no-notice account balance were to exceed

10% of Shipper's TCD, points with no-notice pack quantities

for that Day will have such no-notice quantities adjusted down

by an amount to reduce the pack no-notice account balance to

10% of Shipper's TCD as follows:

(i) The points with pack no-notice quantities for the Day

will be ordered from highest to lowest percentage no-

notice pack quantity.

(ii) The no-notice percentage at the point with the highest

no-notice percentage pack quantity will be reduced to

equal the no-notice percentage at the point with the

second highest no-notice quantity percentage. Such

reduction will be limited so that the no-notice pack

account balance does not go below 10% of Shipper's TCD.

(iii) If after reducing the pack no-notice quantities at the

first point, the pack no-notice account balance remains

in excess of 10% of Shipper's TCD, the no-notice

quantities at the first and second points will be

reduced by an amount such that the percent no-notice

quantity at the first and second points equals the

percent no-notice quantity at the third point. Such

reduction will be limited so that the pack no-notice

account balance does not go below 10% of Shipper's TCD.
