11. OPERATING PROVISIONS FOR TRANSPORTATION AND STORAGE SERVICES

11.1 Nomination and Scheduling of Gas Receipts and Deliveries.

Questar is located in the Mountain Time zone, which is one hour earlier than

all Central Clock times listed below.

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nomination is superseded by the subsequent nomination only to the extent of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.

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.
