The Explicit Confirmation process requires that the Confirming

Party respond to a Request for Confirmation or initiate an

unsolicited Confirmation Response. Absent mutual agreement to

the contrary, Explicit Confirmation is the default methodology.


When a previously confirmed and scheduled quantity is altered,

notification of such alteration should be provided to all of the

below that are affected: 1) Confirmation Requester in a

Confirmation Response (or unsolicited Confirmation Response as

applicable) document by the Confirming Party; 2) Confirming Party

in a Request for Confirmation document by the Confirmation

Requester; 3) Shipper(s) in a Scheduled Quantity document by the

applicable Confirming Party or Confirmation Requester on whose

system the Shipper(s) nomination(s) were made.


Applicable notification(s) of such alterations should be

provided to the affected parties reasonably proximate in time

to the time during which the event causing the alteration was

acted upon by the Confirmation Requester or Confirming Party,

respectively. With respect to the implementation of this process

via the 1.4.x standards, Confirming Parties should send the

applicable document(s) to the applicable party(ies) no later than

the next time they are slated to communicate confirmations or

scheduled quantities (as applicable.)


When a Confirmation Requester receives a Confirmation Response

document from a Confirming Party by the conclusion of a given

quarter hour period, the Confirmation Requester will send to the

Confirming Party's designated site a corresponding Confirmation

Response Quick Response document by the conclusion of the

subsequent quarter hour period. 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.


Confirming Parties' nightly processing and routine maintenance

occurring outside of normal business hours are apt to interrupt

the normal schedule of confirmations/quick response turnaround

stated above. 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.
