(d) Changes to a PDA may be made prospectively

during the month if such changes are approved by Transporter.

Only one PDA may be submitted per gas day. Transporter may in

its reasonable discretion make retroactive reallocations of

transactions to correct for errors. Otherwise, no retroactive

reallocations of any transactions shall be permitted without the

approval of Transporter and the agreement of those Shippers with

service agreements affected by such retroactive reallocations,

provided that the agreement by such affected Shippers shall not

be unreasonably withheld.


(e) PDAs shall remain in effect until a

replacement PDA is received from the interconnecting operator or

upstream title holder; provided, however, PDAs shall be updated

at the beginning of each month. For rank, swing, or percentage

PDAs, the PDA may need to be updated as nominations change.

each day in which Transporter receives gas from or delivers

gas to multiple Shippers at a common Receipt or Delivery

Point in which the quantities received or delivered exceed or

fall short of the sum of the Scheduled Input or Scheduled

Equivalent Quantities for such day, Shippers whose volumes

are commingled at such Delivery or Receipt Point shall have

the obligation to inform Transporter as to the allocation of

such volumes. Transporter shall allocate volumes in accordance

with Operational Balancing Agreements with the operator of the

common Receipt or Delivery Point to the extent Operational

Balancing Agreements are in effect at such points.


6.5 Penalty Provisions Inapplicable. No monthly

imbalance charge shall be assessed unless Transporter has

notified Shipper that an imbalance has occurred or will occur

without corrective action and Shipper has failed to take

action in coordination with Transporter's gas dispatchers

which corrects such imbalance within thirty (30) days of

notification. Transporter will not assess imbalance or

scheduling penalties in the event Shipper's failure to take

corrective action or Shipper's failure to correctly schedule

gas deliveries is caused by Transporter's actions,

interruption of gas supply or transportation service

upstream of Transporter's facilities, or force majeure

conditions as defined in Sections 20 and 21 hereof. Transporter

will also waive any scheduling penalties that might have
