Firm Throughput Services






To initiate service under this Rate Schedule TF, a valid request must be

submitted in accordance with Section 26, "Requests for Service" and Section

27, "Information Required for a Request for Service," of the "GENERAL TERMS

AND CONDITIONS" of this Tariff.


For any Shipper that requests new incremental service under Rate

Schedule TF, Shipper shall have the right to determine the initial MDQ for

one or more of the new incremental Throughput Service(s), TF12 Base, TF12

Variable, TF5 or TFF provided, however, the MDQ for new TF5 shall not exceed

thirty percent (30%) of the Total Aggregate MDQ; except where the total

entitlement level for the Shipper pursuant to previously existing

SS-1, WPS-1 and PS-1 Service Agreement(s) exceeded 30% of the total

entitlement level of all firm services, such level will be available as

TF5. (Hereinafter referred to as the grandfathered seasonal service

percentage.) The Total Aggregate MDQ is exclusive of the TFF MDQ.

The initial Market Area MDQs under the Throughput Service(s) shall

remain in effect, until revised in accordance with the reallocation

provisions set forth in Section 8, "Reallocation of TF Throughput

Levels," of this Rate Schedule.


If a Shipper has a Right of First Refusal (ROFR) or rollover right under its

service agreement, the 70%/30% relationship or the grandfathered seasonal

service percentage for TF12 and TF5 entitlement and the annual TF12

entitlement requirements (collectively, TF Requirements) must be met in any

currently effective entitlement period. Such Shippers may enter into

extensions of entitlement that become effective for some future period and

that do not meet the TF Requirements; however, at the time the extension

becomes effective the TF requirements must be satisfied.


The MDQs for each Throughput Service(s), as such are reallocated from

time to time, shall be set forth in the TF Agreement.


The minimum level of Total Aggregate MDQ applicable to a TF

Agreement under this Rate Schedule shall be 50 MMBtu per day.





Northern will notify Shipper each year on or before November 1 of the

maximum MDQ for TF12 Base, as determined in this Section 8, that will

be effective on the subsequent anniversary date of Shipper's firm TF

Throughput Service Agreement. The Total Aggregate MDQ under the TF

Agreement will remain unchanged.
