1. The TCR Volumetric Surcharge shall be calculated by first annualizing the TCR

Volumetric Surcharge costs by dividing by five (5) years. This quotient is

then divided by the throughput volume used to establish Northern's settlement

rates. The Volumetric Surcharge shall be adjusted prospectively to reflect

any change in the total annual sales and transportation volume determinants in

Northern's future general rate proceedings under Section 4 of the Natural Gas

Act during the five (5) year period. Such adjustments to the Volumetric

Surcharge shall become effective upon the date(s) new rates become effective in

such future rate proceedings.


2. All purchasers of gas under Northern's Sales Rates Schedules and all Shippers

of gas under Northern's Transportation Rates Schedules (collectively referred

as Buyer/Shippers for purposes of this section of the General Terms and

Conditions of this Tariff) shall be charged the applicable TCR Volumetric

Surcharge as set forth on Sheet Nos. 50 through 58 of Volume No. 1 of

Northern's FERC Gas Tariff, as may be revised from time to time, multiplied by

the quantity of gas actually delivered during the billing month.
