GENERAL TERMS AND CONDITIONS

OPERATIONAL FLOW ORDERS

18.3.B When Pipeline May Issue an OFO (Cont.)

5. when Pipeline experiences or forecasts substantially increased requirements due

to changes in weather that could create an operational need for additional

Deliveries; or

6. when Pipeline experiences or forecasts substantially decreased requirements due

to changes in weather or other conditions that could create an operational need

for reduced Receipts; or

7. when hourly Takes by a customer(s) at any Point of Delivery are in excess of

Tariff or contract maximums or are otherwise in excess of quantities that

Pipeline can handle; or

8. when segmentation has resulted in unanticipated operational problems that

jeopardize Pipeline's system integrity or its ability to meet primary firm

service obligations.

C. Pipeline may issue such OFOs when excess Tenders or insufficient Takes by one or more

customers:

1. cannot be tolerated operationally because Pipeline is operating at maximum

allowable operating pressures and/or Pipeline's facilities are full; or

2. jeopardize Pipeline's ability to perform firm services as required by Pipeline's

Service Agreements and this Tariff; or

3. cannot be tolerated operationally because markets directly connected to a Point

of Receipt cannot accept the quantities nominated for Delivery for any reason,

including changes in weather.

D. Pipeline may issue such OFOs when insufficient Tenders or excess Takes by one or more

customers:

1. may cause Pipeline to issue an OFO to another Customer; or

2. cannot be tolerated operationally because Pipeline's line pack is depleted below

the levels required for Pipeline to manage such insufficient Tenders without

jeopardizing Pipeline's ability to perform services as required by Pipeline's

Service Agreements and this Tariff, without limiting firm services or pressures

to other Customers, or without imposing additional OFOs on Pipeline's system; or

3. cannot be tolerated operationally because one or more Customers have failed to

comply with an OFO issued under another subsection; or

4. cannot be tolerated operationally because markets directly connected to such

Point of Receipt require Deliveries of additional quantities for any reason,

including changes in weather.
