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previous nomination is superseded by the subsequent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 nominations process. It is recognized that

the success of seven days a week, twenty-four hours a day

nominations process 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 EBB

down time.


A shipper's nomination of gas to be transported

commencing at 9:00 a.m. Central Clock Time each day shall

conform to GISB Standard 1.3.2(i)-(v). Overthrust will
