Hub Service - Imbalance Resolution Schedule





2.7 Shipper shall be required to arrange the transportation of the gas

to be advanced by Transporter hereunder. Service provided

hereunder shall not commence unless and until Shipper has

demonstrated to Transporter that Shipper has arranged the

transportation of the gas to be advanced hereunder.


2.8 Transporter shall not be required to receive or deliver gas at a

receipt or delivery point where the total quantity of gas for IR-2

Service scheduled is less than that required to operate existing

measurement facilities at such point.




3.1 The maximum and minimum rates per Dth delivered to Shipper for

this Imbalance Resolution Service are set forth on the currently

effective Sheet No. 9 of this tariff. These rates shall be

applicable to service hereunder, unless Transporter and Shipper

have agreed upon a negotiated rate pursuant to Section 17.2 of the

General Terms and Conditions of this Tariff. These rates include

a First Day charge for the quantities of gas for the day of

advance and a charge for each subsequent day until the return of

the gas on a first-out first-in basis. The current Posted Rate

(ranging between the maximum and minimum rates) will be posted on

Transporter's Web Site, which is subject to periodic changes.

Shipper shall pay the current Posted Rate on the date the

Shipper's Hub Nomination Form is received, as verified by

telephone approval, and Shipper's IR-2 service agreement will be

deemed to be so amended.


3.2 If during the term of a IR-2 Service Agreement, Transporter posts

a lower Posted Rate on the Web Site, Shipper's IR-2 service

agreement will be deemed amended to reduce the rate to the

current Posted Rate for the remaining term of the Nomination;

provided however, if the current Posted Rate is subsequently

increased during the term of that Nomination, the IR-2 service

agreement will be deemed amended for the remaining term of the

nomination to reflect the increased rate but no more than the

then-current Posted Rate at the commencement of such Nomination.
