D. Computation of the Unit Fuel Surcharge

The Unit Fuel surcharge shall be determined semi-annually and shall be the sum of the

Gas Unit Fuel Surcharge and the Electric Unit Fuel Surcharge.

1. The Gas Unit Fuel Surcharge shall be computed by dividing the balance of the Summer

or Winter Gas Deferred Fuel Account, as appropriate, plus interest and any

unamortized balance from the prior corresponding recovery period by the estimated

quantity of gas to be delivered during the recovery period, excluding Transporter's

Western Division deliveries and quantities which are received and delivered in

Transporter's Market Area.

2. The Electric Unit Fuel Surcharge shall be computed by dividing the balance of the

Summer or Winter Electric Deferred Fuel Account, as appropriate, plus interest and

any unamortized balance from the prior corresponding recovery period by the estimated

quantity of gas to be delivered during the recovery period, excluding Transporter's

Western Division deliveries and quantities which are received and delivered in

Transporter's Market Area.

E. Deferred Fuel Account

Transporter shall establish and maintain separate Gas and Electric Deferred Fuel Accounts

for the Summer and Winter Periods. For each billing month, the applicable seasonal Gas

Deferred Fuel Account shall be increased or decreased by the volumetric difference between

retained fuel and actual fuel (including actual quantities delivered to party(ies) as

payment for compression services provided to Transporter and lost and unaccounted for

quantities) valued at the simple arithmetic average of the Sales Posted Price and the

Purchase Posted Price as defined in the monthly balancing provisions of Section 14.
