19.4 Nominations (Continued)

 

19.4(c) Changes to Nominations (Continued)

 

Such nominations must be received by GTN's Transportation

Department in accordance with the scheduling timelines set

out in Section 19.4(b).

 

In the event GTN does not receive information of upstream

or downstream adjustments, GTN shall use the lesser of the

new nomination or the previous nomination.

 

(2) Intraday Nominations

 

In accordance with NAESB Standard 1.3.8, Version 1.8,

all transportation service providers should allow for

intraday nominations. Requests to amend previously

scheduled nominations may be accepted during the gas

day, subject to operational conditions and, further

that corresponding upstream and downstream adjustments

in a manner satisfactory to GTN can be confirmed. In

accordance with NAESB Standard 1.3.11, Version 1.8,

such intraday Nominations can be used to request

increases or decreases in total flow, changes to

receipt points, or changes to delivery points of

scheduled gas. A request to increase a nomination for

firm transportation up to the MDQ specified in the

Service Agreement will be accommodated to the extent

operating conditions permit. Firm intraday nominations

other than during the Intraday 2 Nomination Cycle shall

have priority over nominated and scheduled

interruptible volumes. A request to increase a

nomination for interruptible transportation shall be

permitted only to the extent that capacity is available

and that no displacement of other interruptible

transportation occurs. Such changes will become

effective only when system operating conditions, as

determined by GTN, permit changes to occur.
