GENERAL TERMS AND CONDITIONS

12. SCHEDULING PRIORITIES AND CURTAILMENT POLICY (Continued)

(b) If previously Scheduled Quantities will be reduced as a

result of bumping, Transporter will report such reductions on its

Designated Site .

12.7 Previously Scheduled Quantities at the Agreement Level

To the extent that a Shipper, by nomination, revises Scheduled

Quantities on a service agreement through a receipt or delivery point,

on the mainline or on a lateral in subsequent Nomination cycles, the

quantity that remains scheduled on such Agreement through such point

after the revision will not be considered a new Nomination through the

point.

12.8 Curtailment Policy

If Transporter determines that operationally available capacity

through any constraint point on its system has been reduced for

any reason whatsoever to a level insufficient to accommodate all

previously Scheduled Quantities, in the next scheduling cycle,

Transporter will fill the reduced operationally available capacity

as follows:

i) Elapsed-Prorated Scheduled Quantities will be scheduled

first;

ii) Previously Scheduled Quantities will be scheduled second

and will be scheduled using the priority levels delineated

in Sections 12.1, 12.2, 12.3 or 12.4 above, except that

Transporter will use the CD of the Firm Service Agreement as

the basis for filling the reduced operationally available

capacity (once scheduled in a NAESB cycle, Secondary Firm

Nominations are deemed Primary Firm Nominations).

12.9 Shipper Notice Responsibility

Upon receipt of Transporter's notification of Scheduled Quantities under

Section 12, Shipper will have the responsibility to inform its end-

users, suppliers and all others involved in the affected transaction,

except parties that interconnect with Transporter.
