10. GAS INDUSTRY STANDARDS BOARD ("GISB")

Transporter's tariff meets or exceeds all the Business Practices and

Electronic Communication Standards which were required by the

Commission in 18 CFR 284.10(b) in accordance with Order No. 587 issued

July 17, 1996. Transporter is hereby incorporating GISB Version 1.2 of

the definitions and/or standards described below:

Number Definition/Standard

1.2.2 All trading partners should accept all GISB standard data elements.

Usage should be characterized as either mandatory, conditional,

sender*s option, business conditional, and mutually agreeable.

Mandatory (M) means that the data element (information) must be

supplied in the transaction.

Conditional (C) means that the presence of data in a field is

determined by the presence or lack of data in another field within the

transmittal or related data sets.

Sender*s option (SO) means that this element is optional for the

sender to send and, if sent, the receiver should receive and process.

Business conditional (BC) means that the data element is based on

current variations in business practice. The business practice will

be described herein, with an example. Over time, GISB expects that as

business practices are standardized, elements will move out of this

category. Business Conditional elements which are not

supported/required by the receiver will be acknowledged in the

response document with a warning message code indicating that the data

elements was ignored by the receiver.

Mutually agreeable (MA) means that the data element is mutually agreed

to between trading partners. It must be presented to GISB for

technical implementation. It does not, by its definition, create a

GISB standard business practice. Usage of this element in no way can

be mandated for inclusion by either trading partner in order to

achieve a level of service.

1.2.3 Pooling is: (1) the aggregation of gas from multiple physical and/or

logical points to a single physical or logical point, and/or (2) the

dis-aggregation of gas from a single physical or logical point to

multiple physical and/or logical points.

1.2.5 A package ID is a way to differentiate between discrete business

transactions.

1.3.15 When the fuel reimbursement method is in-kind, the results of the fuel

reimbursement calculation for the nomination process should be rounded

to the nearest dekatherm or Gigajoule (Canada).

1.3.16 Where fuel reimbursement is in kind, the standard fuel calculation

mechanism, as this is related to the nomination process, should be (1-

fuel %/ 100) multiplied by receipt quantity = delivery quantity.
