4. CHANGES IN RATES FOR THIS RATE SCHEDULE TO REFLECT CHANGES BY NATURAL GAS COMPANIES PROVIDING

STORAGE AND RELATED TRANSPORTATION SERVICES TO SELLER

4.1 Application - This section sets forth the procedures to change Seller's rates under

this rate schedule when the natural gas companies providing storage and transportation

services necessary to provide storage service under this rate schedule change the

rates and charges payable by Seller for such services, and to flow through refunds

received from such natural gas companies.

(a) Rate Change - The charges under this rate schedule, as shown on effective Sheet

No. 27 of Volume No. 1 of this Tariff, reflect, as appropriate, amounts payable

by Seller to National Fuel for storage service under National Fuel's Rate

Schedule SS-1, and for storage-related transportation service under National

Fuel's Rate Schedule X-54. The services provided by National Fuel (hereinafter

referred to as "Supplier") are utilized by Seller to render service to Buyer

under this rate schedule. A change in charges payable by Seller to Supplier

shall be reflected in this rate schedule by the following procedure:

(i) Demand Charge - The Demand Charge shown on Sheet No. 27 of this Tariff is

based on the Monthly Deliverability and Monthly Reservation Charges to be

paid by Seller to Supplier for related storage and transportation

services and Seller's demand costs for delivery of storage quantities on

its pipeline system. Seller shall reduce or increase, as appropriate, the

Demand Charge shown on such Sheet No. 27 to reflect the change in

Supplier's Monthly Deliverability and Monthly Reservation Charges.

(ii) Storage Capacity Quantity Charge - The Storage Capacity Quantity Charge

shown on Sheet No. 27 of this Tariff is based on the Storage Capacity

Charge to be paid by Seller to National Fuel for storage service. Seller

shall reduce or increase the capacity charge shown on such Sheet No. 27

to reflect the change in the National Fuel Storage Capacity Charge.

(iii) Charges for Quantities Injected and Withdrawn - The Quantity Injected and

Quantity Withdrawn charges shown on Sheet No. 27 of this Tariff are based

on the commodity costs/charges of Supplier to inject and withdraw Buyer's

storage quantities. Seller shall reduce or increase, as appropriate, the

Quantity Injected and the Quantity Withdrawn Charges shown on Sheet No.

27 to reflect the commodity charges of Supplier.

(b) Notification - Seller shall give notice via its electronic bulletin board of any

proposed rate change filed by National Fuel which Seller is authorized to track

under this rate schedule within three (3) business days following Seller's

receipt of such filing. Such notice shall include the expected effect on

Seller's rates under this Rate Schedule.

Fuel which affects Seller's rates under this rate schedule no later than thirty

(30) days following the issuance date of the Commission order which accepts and

makes effective National Fuel's rate change. The effective date of such change

in Seller's rates shall coincide with the effective date of any change in rates

by National Fuel.

(d) Refunds - Within forty-five (45) days of the receipt thereof, Seller shall refund

to its customers under this Rate Schedule all amounts refunded to Seller by

Supplier under the related storage and transportation rate schedules, including

any interest paid by Supplier. Each customer's proportionate part of such refund

shall be determined in the same manner as the refund from Supplier was

determined.
