GENERAL TERMS AND CONDITIONS

Requesting and Scheduling Service

11A.5. Allocation of Receipts and Deliveries.

A. Prior to allocation of actual gas flow among nominated

services, Pipeline must receive either (1)a Rate Schedule

DPO service agreement or (2)a predetermined allocation from

the upstream or downstream custody transfer party,

consistent with the most current form of PDA from

Pipeline's EBB, for flowing gas supply. There is no need

to submit a Rate Schedule DPO service agreement or PDAs

where Pipeline has an operational balancing agreement in

effect for a point. A Rate Schedule DPO service agreement

or PDA at the city gate delivery points where Pipeline is

providing service under Rate Schedule FTNN must be

consistent with Section 6.3, above. Where a PDA applies,

only one PDA methodology is to be applied per allocation

period.

B. At points where it interconnects with other pipelines,

Pipeline shall determine the flow of gas in accordance with

Operational Balancing Agreements (OBAs) between Pipeline

and the other pipeline, as applicable. At city gate

Delivery Points where Pipeline provides service under Rate

Schedules FTNN or DPO, Pipeline shall determine the flow of

gas in accordance with Section 6.3, above. At all other

points, Pipeline shall determine the flow of gas in

accordance with either the provisions of Rate Schedule DPO

or Predetermined Allocations (PDAs) among Customers behind

such points, as provided by the operator of such points.

PDAs will be either ranked, pro rata, percentage, swing, or

operator provided value. These determinations shall be

made to the extent that such OBAs or PDAs are in effect and

made known to Pipeline after or during confirmation and

before the start of the Day. Pipeline will provide

indication of its receipt of a PDA that has been submitted

electronically, within 15 minutes. Based on scheduled

nominations, Pipeline will adjust receipts from the party

designated by the PDA, who shall be subject to applicable

imbalance provisions of this Tariff. If an operator has

not entered into a Rate Schedule DPO service agreement with

Pipeline and provides no PDA, Pipeline will resort to pro

rata allocation of variations between scheduled nominations

and actual gas flow.

C. The time limit for disputes of allocations shall be six months

from the date of the initial month-end allocation, with a

three-month rebuttal period. This standard shall not apply

in the case of deliberate omission or misrepresentation or

mutual mistake of fact. Parties' statutory or contractual rights

shall not otherwise be diminished by this Section 11A.5.C.
