(e) Deliveries at Pipeline Interconnections. An imbalance for

an OBA Party shall be based on the difference between total

actual quantities of gas received or delivered through the

affected meter and the total aggregated scheduled

quantities for that meter. Under the OBA, the total

aggregated scheduled quantities for that meter shall be

deemed to be the actual quantities of gas received or

delivered for each Shipper. Imbalances will be resolved

under the OBA between Pipeline and the OBA Party.

13.4 Determination of Receipts and Deliveries to Resolve Imbalances.

Imbalance quantities that are being resolved in kind shall be

deemed to be the last through the meter.

13.5 Upstream Pipeline Flexibility. Shipper may deviate from its

scheduled firm transportation quantity on a Gas Day by satisfying

the requirements herein; provided that nothing herein shall

authorize Shipper to receive gas under its firm transportation

services on Pipeline, including any no-notice flexibility, in

excess of Shipper’s MDTQ.

(a) SNG. To the extent allowed under an OBA between Pipeline

and SNG, a Shipper subscribing to no-notice transportation

service under SNG’s Rate Schedule FT-NN may elect through

the Internet Website to have any allocated unscheduled

quantities reported to SNG to resolve daily imbalances on

Pipeline up to Shipper’s no-notice entitlement on SNG. In

order for Shipper to receive no-notice flexibility on a Gas

Day, Shipper shall, prior to the completion of the last

nomination cycle: (i) ensure that its no-notice entitlement

is reported to Pipeline by SNG; and (ii) elect through the

Internet Website to have Pipeline report to SNG allocated

unscheduled quantities for that Gas Day. If conditions (i)

and (ii) are not met, the allocated unscheduled quantities

will result in an imbalance under GT&Cs Section 19 for the

Gas Day the imbalance was incurred. Pipeline will not

report to SNG changes to the original allocation later than

5:00 P.M. CCT on the second calendar day following the end

of the Gas Day.
