Intraday nominations from a Shipper's effective FDD, PDD or IDD accounts will

be scheduled subject to the storage parameters and available throughput

capacity. If feasible, nominations throughout the gas day will be recognized

to the extent they can be scheduled and confirmed. For firm service any such

intraday nomination may not result in Shipper exceeding its MDQ. Shipper may

nominate volumes in excess of the MDQ, but such nomination would be subject

to the terms and conditions of the TI Rate Schedule.


Northern shall have the right at any time to limit acceptance of an intraday

nomination on a non-discriminatory basis if system integrity will be placed in

jeopardy. Such limitations may include, but are not limited to, a requirement

that a receipt and delivery point must be either both in the Field Area or both

in the Market Area. Any such limitation shall be posted on Northern's

website with its justification.





(a) Scheduling


Firm Throughput Services at Primary Points shall be scheduled first and

shall be given the highest priority. Firm Throughput Service at Alternate

Points shall be scheduled next, before interruptible volumes. Nominations

received after the nomination deadline will be scheduled after the

nominations received before the nomination deadline.


In the event capacity must be allocated on part or all of Northern's

system, then on the respective part of Northern's system, Firm Throughput

Services shall be given the highest priority for scheduling purposes.

Therefore, Northern will schedule firm throughput customers' volumes in

accordance with the provisions of Section 19, "Limitations on Northern's

Obligation to Provide Firm Service" of the GENERAL TERMS AND CONDITIONS.


Northern will use shipper-provided path priorities and rankings when

making reductions during the scheduling process, when the path

priorities and rankings do not conflict with other provisions within

Northern's tariff.


In the Market Area, in the event more than one firm Shipper nominates the

same alternate delivery point, the point will be allocated for scheduling

purposes among the firm Shippers nominating the alternate delivery point on

a pro rata basis. In the Field Area, in the event more than one firm

Shipper nominates the same alternate delivery point, the scheduling

priority for the Shipper nominating within the contract path will be before

the Shipper nominating outside the contract path. All within-the-path

alternate delivery points will be scheduled on a pro rata basis; all

outside-the-path alternate delivery points will be scheduled on a pro rata

basis. Scheduling priority for firm service at an alternate delivery point

will be before interruptible service but after firm service at a primary

firm point. A Shipper using a primary point and nominating prior to the

nomination deadline, will be scheduled prior to interruptible service.

Shippers using alternate delivery points may bump TI Shippers at any time

in accordance with Section 28, "Nominations" of the GENERAL TERMS AND

CONDITIONS of this Tariff.
