19.4(a) Information to be Provided with Nomination (Continued)

Shipper shall provide as a component of its nomination such

business conditional data sets as may be required by GTN to

enable it to identify, confirm, and schedule the nomination.

Shipper shall also prioritize nominated receipts and deliveries

when there is more than one supplier and more than one Shipper

customer, respectively. Shipper designated priorities will be

used to allocate gas when upstream and downstream nominations

vary from GTN's Shipper nominations.

Shipper may nominate for any period of days, provided the

nomination begin and end dates are within the term of the

Shipper's Transportation Service Agreement or exhibit. Such

nominations shall be deemed "Standing Nominations." All types

of Nominations must be clearly and separately identified so

that priorities of service can be distinguished. As required

by NAESB Standard 1.3.19, Version 1.8, overrun quantities

should be requested on a separate transaction.

The receipt of the nomination is notice that all necessary

regulatory approvals have been received and that valid upstream

and downstream transportation and other contractual

arrangements are in place.
