GENERAL TERMS AND CONDITIONS

13. NOMINATING AND SCHEDULING TRANSPORTATION SERVICE (Cont'd.)

(a) Standard Nominations. A "standard nomination" is a nomination

for transportation service beginning at the start of a day and

ending at the end of a day. All nominations should include

shipper defined begin dates and end dates. All nominations

excluding intra-day nominations should have roll-over options.

Specifically, shippers should have the ability to nominate for

several days, months, or years, provided the nomination begin

and end dates are within the term of shipper's contract. A

standard nomination should be based on a daily quantity, and

may be modified either by a superseding standard nomination or

by an intra-day nomination as described in Section 13.1(b).

A standard nomination which is superseded by an intra-day

nomination shall, at the conclusion of the day on which the

intra-day nomination was in effect, revert to the quantities,

locations and end date submitted in the superseded standard

nomination. A standard nomination which is superseded by a

standard nomination shall, at the conclusion of the end date

in the superseding standard nomination, revert to the quanti-

ties, locations and end date submitted in the superseded

standard nomination.

(b) Intra-day Nominations. If Shipper desires to initiate or

modify transportation service effective at any time at or

after 1:00 p.m. central clock time on the effective day of the

nomination, Shipper shall provide Transporter with a completed

Customer Nomination specifying the effective date and time,

and received by Transporter at least two hours before gas

flow, subject to confirmation received by Transporter no later

than one hour before gas flow that the delivering and receiv-

ing parties will implement such revision and adjust gas flows

accordingly. An intra-day nomination should be based on a

daily quantity; thus, an intra-day nominator need not submit

an hourly nomination. The interconnected parties must agree on

the hourly flows of the intra-day nomination, if not otherwise

addressed in Transporter's contract or tariff. An intra-day

nomination shall span only a single day, terminating at the

conclusion of the day on which the intra-day nomination is

effective. Intra-day nominations will be processed after

timely standard nominations have been
