Pooling is: 1) the aggregation of gas from multiple physical and/or logical points to a single

physical or logical point and/or 2) the dis-aggregation of gas from a single physical or logical

point to multiple physical and/or logical points. Pooling points have been established in

Northern's Field and Market Areas to provide Shippers and Pooling Customers the means to

aggregate supplies using a Pooling and/or Throughput Service Agreement for deliveries at a

pooling point, in accordance with Rate Schedule MPS or the applicable Throughput Rate Schedule.


Northern and Shipper shall establish a procedure to electronically exchange information

regarding receipt and delivery quantities in dekatherms to achieve a daily operational gas

balance, and Shipper shall, upon request, furnish such data as Northern deems necessary to

maintain control of its system, including, without limitation, established Btu content of the

gas to be received by Northern. If Northern determines in its reasonable discretion that

confirmation of nominations at certain Point(s) of Receipt and/or Delivery are necessary to

maintain the integrity of its system, Northern will not schedule transportation unless the party

causing the gas to be delivered for Shipper's account into Northern's system at the Point(s) of

Receipt confirms such deliveries and that the party receiving gas from Northern's system for

Shipper's account at the Point(s) of Delivery confirms that it will receive such volumes.
