GENERAL TERMS AND CONDITIONS

(continued)

22.5 Intra-day Nominations

A. There is no limitation as to the number of intra-day nominations (line items as per NAESB

WGQ Standard 1.2.1) which a service requester may submit at any one standard nomination

cycle or in total across all standard nomination cycles. Such nominations must be

submitted on a currently existing Service Agreement.

B. Shipper shall have ability to nominate on an intra-day basis on Transporter's

system under the following conditions:

1. Intra-day nominations may be used to request an increase or

decrease in scheduled volumes or a change in receipt or delivery points,

consistent with Shipper's Service Agreement. A nomination reduction shall

not result in a revised nomination which is less than the volume of gas

received or delivered on behalf of such Shipper by Transporter on that gas

day.

2. Shipper must obtain prior confirmation from all affected upstream

and downstream Operators.

3. Intra-day nominations will be scheduled only if operationally

feasible.

4. Intra-day nominations do not rollover and are applicable to one (1)

day only.

5. Intra-day nominations may be used to nominate new supply or market.

C. In order to nominate on an intra-day basis, Shipper must submit to Transporter

the information required in Section 22.1. In addition, intra-day nominations

should include an effective time.

D. Firm intra-day nominations are entitled to bump scheduled interruptible service

only during the Evening and Intraday 1 Nomination cycles. Transporter will

provide advance notice of bumping to interruptible shippers. Such notice will be

provided in the same manner in which Transporter provides notice of Operational

Flow Orders. Transporter will provide notification of bumped volumes through the

scheduled quantities statement. Transporter will also electronically communicate

notice directly to bumped Shippers in accordance with the grid-wide timeline for

scheduled quantities.
