6.1 (continued)


The quarter hour periods will be defined to begin on the

hour and at 15, 30 and 45 minutes past the hour. A given

quarter hour will contain all transactions whose receipt

time is less than the beginning of the subsequent

quarter hour. (NAESB Standard 1.3.37)


(v) Transporter's nightly processing and routine maintenance

occurring outside of normal business hours are apt to

interrupt the normal schedule for Nominations/quick

response turnaround stated in NAESB Standard 1.3.37.

Such delays should be kept to a minimum. The normal

schedule should be resumed at the earliest opportunity

and no later than the start of normal working hours the

following day, seven days per week. (NAESB Standard



(b) Nomination Data Elements.


(i) All Nominations should be considered original

Nominations and should 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within that range, the previous Nomination is superseded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.

(NAESB Standard 1.3.7)


(ii) Certain Nomination data elements are identified as "key"

fields and define the basis of a unique Nomination

record. Changes to non-key data elements will cause a

previous Nomination containing the same key data

elements to be replaced. Transporter's mandatory and

optional data elements are available on Transporter's

EBB or by facsimile. Such data elements shall conform to

the requirements of Data Dictionary standards as set

forth in NAESB Standard 1.4.1.
