13. ALLOCATION AND IMBALANCES

13.1 Introduction

Imbalances result whenever the amount of gas a Shipper receives from

Transporter's system differs from the amount that Shipper delivered

into Transporter's system (net of various adjustments). Imbalances

can result from a difference between the amount of gas nominated at a

particular receipt or delivery point and the amount of gas measured

actually passing through that point. This Section 13 describes Trans-

porter's methodology for allocating shortfalls and overruns at receipt

and delivery points, and includes the various control measures in-

tended to discourage, minimize and correct imbalances.

Scheduled receipts and deliveries will be the basis for allo-

cation of actual deliveries or receipts. The allocation methodology

applied to actual deliveries or receipts shall be determined in

accordance with an Operational Balancing Agreement as set forth in

Section 13.2 (c)(i) hereof, or the default methodologies set forth in

Sections 13.3(b)(ii), 13.3(c)(ii), 13.4(b)(ii), and 13.4(c)(ii)

hereof.
