TRANSPORTATION GENERAL TERMS AND CONDITIONS
21.1 Balancing of thermally equivalent quantities of gas received and
delivered by GTN shall be achieved as nearly as feasible on a
daily basis, with any cumulative imbalance accounted for on a
monthly basis. Correction of imbalances shall be the
responsibility of the Shipper whether or not notified by GTN at
the time of incurrence of the imbalance. Correction of imbalances
shall be scheduled with GTN using the nomination process as soon
as an imbalance is known to exist based on the best available
current data. Nominations to correct imbalances shall have the
lowest priority for scheduling purposes and shall be subject to
the availability of capacity and other operational constraints for
imbalance correction. If on any day capacity is insufficient to
schedule all imbalance nominations, all such nominations shall be
prorated accordingly. To maintain the operational integrity of its
system, GTN shall have the right to balance any Shipper's account
as conditions may warrant.
Imbalance penalties will apply during constraint periods when it
is necessary to maintain or restore the operational integrity of
the pipeline system and to ensure: adequate pipeline pressures to
provide efficient and reliable transportation services; adequate
system line pack to deliver on demand; service to all Shippers for
all firm services; and a balanced system for the foregoing
purposes. Imbalances shall exist as defined below and be subject
to the applicable charges and penalties if not corrected.
(a) Actual delivered quantity exceeds MDQ
Authorized Overruns are interruptible in nature and will be
subject to the Authorized Overrun charge, which is equal to the
rates and charges set forth for interruptible service under
Rate Schedule ITS-1, and such Authorized Overruns shall be
subject to the priority of service provisions of Paragraph 19
of these Transportation General Terms and Conditions.
An imbalance shall exist when GTN has not authorized deliveries
in excess of a Shipper's MDQ. Under these circumstances, GTN
may, without notice, adjust Shipper requests for confirmation
from receipt and delivery markets on GTN's system.
Penalty: For unauthorized deliveries in excess of a Shipper's
MDQ, a Shipper shall be assessed a penalty equal to two (2)
times the maximum applicable interruptible transportation rate
for the quantity that is greater than 10% of the MDQ or 1000
Dth, whichever is greater.
