Firm Throughput Services


The maximum TF12 Base entitlement shall be the Shipper's actual

average daily deliveries, including (1) total injections to the Ogden

deferred delivery point and positive net injections to the Demarc

deferred delivery point for FDD, PDD, IDD, or (2) third party

storage; to the Town Border Stations (TBS's) or delivery points

listed as primary delivery points in the Shipper's TF Service

Agreement(s), from Northern's system over the preceding five (5)

month summer period, May through September. Furthermore, if the

Shipper is the delivery point operator such daily deliveries shall

(1) include all deliveries made to such TBS's under any TF Service

agreement on an alternate point basis, and (2) include all deliveries

made to such TBS's or delivery points under any TI Service Agreement,

and (3) include all deliveries made to such TBS's or delivery points

as a result of Capacity Release transactions described in Section 47

of the GENERAL TERMS AND CONDITIONS of this tariff. Deliveries

pursuant to a TFX, GS-T, or LFT Service Agreement shall be excluded.


To the extent the TF12 Base entitlement is adjusted, the TF12

Variable entitlement shall be adjusted in the opposite direction in a

like amount.


The MDQs for the TF12 Base and TF12 Variable Throughput Service(s)

shall be subject to reallocation in accordance with this Section 8

annually; provided, however, the TF Agreement must be effective for

at least one (1) year before the MDQs may be reallocated. In no

event shall Shipper modify on an annual basis the MDQ levels for the

TF5 service. This reallocation process will not affect TF5 MDQ

unless allowed as a result of Section 47. Additionally, this

reallocation process shall not result in an automatic change to

Northern's reservation rates.


The provisions of this Section 8 shall apply in the same manner when

a Shipper has multiple TF Service Agreements at the same point(s).

Provided, however, daily deliveries to the TBS or delivery points

shall be allocated among the TF agreements on a pro rata basis, using

the Total Aggregate MDQ's of each TF agreement, unless Northern and

Shipper agree in writing to a different allocation upon the

effectiveness of the multiple contract situation.




The GENERAL TERMS AND CONDITIONS of this Tariff are hereby

incorporated into and made a part of this Rate Schedule.
