GENERAL TERMS AND CONDITIONS

Requesting and Scheduling Service

11A.3 Nomination Of Receipts And Deliveries.

A. Customer shall nominate the total daily quantity to be

received or delivered by Pipeline to Customer, or for

Customer's account, under all rate schedules, at the

Receipt and Delivery Points set forth in each Service

Agreement between Pipeline and Customer. All nominations

should include Customer- defined begin dates and end dates.

All nominations excluding intra-day nominations should have

roll-over options. Specifically, Customers may nominate

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

begin and end dates are within the term of Customer's

Service Agreement. Overrun quantities must be requested in

a separate transaction. Such nominations shall be in

uniform daily quantities. All nominations are 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superseded by the subsequent nomination only to the extent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.
