15.1 Daily Scheduling. Overthrust is located in the Mountain Time

zone, which is one hour earlier than the Central Clock Time listed below.


Except for intra-day nominations, all nominations shall be

considered original nominations and must be replaced to be changed. When a

nomination for a date range is received, each day within that range is

considered an original nomination. When a subsequent nomination is received

for one or more days within that range, the previous nomination is superseded

by the subsequent nomination only to the extent of the days specified. The

days of the previous nomination outside the range of the subsequent

nomination are unaffected. Nominations have a prospective effect only.


All nominations shall include Shipper-defined begin dates and end

dates. All nominations, excluding intra-day nominations, shall have roll-

over options. Specifically, Shippers shall 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. Nominations received after

nomination deadline shall be scheduled after the nominations received before

the nomination deadline.


All parties shall support a seven-days-a-week, twenty-four-hours-

a-day Questline service. It is recognized that the success of seven days a

week, twenty-four-hours-a-day Questline service is dependent on the

availability of affected parties' scheduling personnel on a similar basis.

Party contacts need not be at their ordinary work sites, but shall be

available by telephone or pager. Shippers may tender nominations via

facsimile transmission during system down time.


Third Party Account Administrators (3PAD) wishing to provide title

transfer tracking (TTT) services on Overthrust's system shall notify

Overthrust in writing. If the terms are acceptable to both parties,

Overthrust and the 3PAD will enter into an agreement that will describe the

points where TTT transactions will be processed by the 3PAD and the

coordination of activities between the 3PAD and Overthrust.


A Shipper's nomination of gas to be transported commencing at

9:00 a.m. Central Clock Time each day shall conform to NAESB Standard
