6.2 Confirmation and Scheduling Criteria. (GISB Standard 1.3.22)


(a) For request to confirm and Confirmation response processes,

all Parties will seek to confirm by means of communicating

at the applicable detail/summary level all transactions with

respect to a location. (GISB Standard 1.3.35)


(b) In the Confirmation process, where a party requesting

Confirmation (a Confirmation Requester) is not itself a

Transportation Service Provider, the location code to be

used when sending a Request for Confirmation should be the

location code associated with the location where Gas will be

scheduled by the Transportation Service Provider; and, where

a Confirmation Requester is also a Transportation Service

Provider; then, as between these confirming parties (the

Confirmation Requester and the Confirming Parties), and

absent their mutual agreement to the contrary, the location

code to be used when sending a Request for Confirmation

should be the location code used by the Transportation

Service Provider sending the Request for Confirmation. (GISB

Standard 1.3.36)


(c) The receiver of the Nomination initiates the Confirmation

process. The Confirming Party that would receive a Request

for Confirmation or an unsolicited Confirmation Response may

waive the obligation of the sender to send. (GISB Standard



(d) When a Confirmation Requester receives a Confirmation

Response document via EDI 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 via EDI, 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. (GISB Standard 1.3.45)
