3.4 Intra-day Nominations

An intra-day nomination is any nomination submitted after the

deadline set forth in Section 3.3 whose effective time is no earlier

than the beginning of the gas day and runs through the end of that

gas day. An intra-day nomination shall not roll-over, and shall not

replace the remainder of a standing nomination. There is no need to

renominate if the intra-day nomination modifies the existing

nomination. The nomination should include Shipper defined begin

dates and end dates. A nomination should be considered an original

nomination, and should be replaced to be changed and shall have a

prospective effect only unless otherwise agreed to between

Transporter and Shipper. The intra-day nomination shall include an

effective date and time and daily quantity to be transported.

Shipper and Transporter shall agree on the hourly flows of the

intra-day nomination, however, Transporter shall not be obligated to

transport an hourly amount greater than one-twenty-fourth of

Shipper's MDQ. An intra-day nomination may be utilized to request

increases or decreases in gas flow and/or changes to receipt and/or

delivery points of scheduled gas. Shipper may submit intra-day

nominations at least four hours prior to the commencement of the

requested change in gas flow, subject to confirmation and

verification and Transporter's operating conditions.

Thus, Transporter will support the following standard nomination

cycles:

The Evening Nomination Cycle: 6:00 pm for nominations leaving control

of the nominating party; 6:15 pm for receipt of nominations by the

transporter; 6:30 pm to send Quick Response; 9:00 pm for receipt of

completed confirmations by transporter from upstream and downstream

connected parties; 10:00 pm for Transportation Service Provider to

provide scheduled quantities to affected shippers and point

operators, and to provide scheduled quantities to bumped parties

(notice to bumped parties), (central clock time on the day prior to

flow).

Scheduled quantities resulting from an Evening Nomination that does

not cause another Service Requester on the subject Transportation

Service Provider to receive notice that it is being bumped should be

effective at 9:00 am on gas day; and when an Evening Nomination

causes another Service Requester on the subject Transportation

Service Provider to receive notice that it is being bumped, the

scheduled quantities should be effective at 9:00 am on gas day.
