GENERAL TERMS AND CONDITIONS

(Continued)

6. NOMINATIONS AND SCHEDULING PROCEDURES

6.1 (b) Nomination Data Elements (Continued)

(iii) Transporter's Key Nomination data fields are composed

of: service requester contract (Service Agreement),

transaction type, Upstream Party, upstream contract

(when applicable), receipt location (as applicable),

Downstream Party (as applicable), downstream contract

(when applicable), Delivery location (as applicable),

package ID, upstream package ID (where mutually

agreed), downstream package ID (where mutually

agreed), capacity type indicator (where mutually

agreed). Upon receipt by a service provider from a

service requester of a transaction whose key elements

match those previously received by the service

provider from the service requester, the service

provider should then process the begin date/time and

end date/time consistent with the intentions of the

GISB Standard 1.3.7 and then process the rest of the

transaction's data elements consistent with the

applicable standards to determine the business

results. When data is not supplied (e.g. is not

applicable, is not supported or is not mutually agreed

upon) the pertinent portion of the key would be

determined to be null. (GISB Standard 1.3.27)

(iv) Nominations must specify a Begin and End Date. Such

dates must be no earlier than the effective date or no

later than the termination date of the service

agreement. Each Day, all Nominations for the next Day

which have been received by Transporter at or prior to

the Nomination Deadline shall be processed pursuant to

Section 6.

(v) All Nominations, including Intraday Nominations,

should be based on a daily quantity; thus, an Intraday

nominator need not submit an hourly Nomination.

Intraday Nominations should include an effective date

and time. The Interconnected Parties should agree on

the hourly flows of the Intraday Nomination, if not

otherwise addressed in Transporter's contract or

Tariff. (GISB Standard 1.3.9)
