6.1 (a) Nomination Procedures and Deadlines (Continued)


(iv) 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 GISB

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. (GISB Standard 1.3.38)


(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Nomination is superseded by the subsequent Nomination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. (GISB 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 GISB Standard 1.4.1.
