GENERAL TERMS AND CONDITIONS

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 the data element is based on

current variations in business practice. The business practice

will be described herein, with an example. Over time, NAESB 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 element 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 NAESB

for technical implementation. It does not, by its definition,

create a NAESB 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.

2.30 Critical Notices. The term "Critical Notices" should be

defined to pertain to information on transportation service

provider conditions that affect scheduling or adversely affect

scheduled gas flow.

2.31 NAESB Standards. The term "NAESB Standards" shall mean the

business practices, electronic communication, and data dictionary

standards which were issued by the Wholesale Gas Quadrant (WGQ) of

the North American Energy Standards Board (NAESB) and adopted by the

Commission.

In addition to the NAESB standards incorporated within the text of

other provisions of this FERC Gas Tariff, Tuscarora incorporates by

reference the following standards by level of compliance:
