TRANSPORTATION GENERAL TERMS AND CONDITIONS
                                  (Continued)
   
     6. Critical Notices - Pertain to information on transportation service
provider conditions that affect scheduling or adversely affect scheduled gas
flow.
   
     7. Data Dictionaries - shall mean those documents created by the
Standards Board which implement the Standards Board Standards, and which
specifically define the business names for the various elements of the
Standards Board Standard data sets.  The Data Dictionaries also define
the appropriate usage of the data element (for example, Mandatory,
Conditional, Sender's Option, Business Conditional, and Mutually
Agreeable).  Transporter has, as part of its implementation of the
Standards Board Standards, incorporated by reference, the following
Standards Board Data Dictionaries:  1.3.2(vi), 1.4.1 through 1.4.7, 2.4.1
through 2.4.16, 3.4.1 through 3.4.4, 5.4.1 through 5.4.22 and the
standards contained in Recommendation R02002.
   
     8. Day - A period of twenty-four (24) consecutive hours (except for
those days adjusted for Daylight Savings Time) commencing at nine (9:00) a.m.
Central Clock Time (eight (8:00) a.m., Mountain Clock Time).
   
     9.   Dekatherm ("Dth") - One dekatherm is the quantity of heat energy
equivalent to one million British thermal units (MMBtu).  Dth is the standard
quantity for Nomination, Confirmations and Scheduling per gas day in the
United States, gigajoules per gas day in Canada and gigacalories per gas day
in Mexico.   (For reference, one (1) dekatherm = 1,000,000 Btu's; 1
gigajoule = 1,000,000,000 joules; and 1 gigacalorie = 1,000,000,000
calories.)  For commercial purposes the standard conversion factor between
dekatherms and gigajoules is 1.055056 gigajoules per dekatherm and between
dekatherms and gigacalories is 0.251996 gigacalories per dekatherm.
The standard Btu is the International Btu which is also called the Btu (IT);
the standard joule is the joule specified in the SI system of units.  (The
International Btu is specified for use in the gas measurement standards of
the American Gas Association, the American Petroleum Institute, the Gas
Processors Association and the American Society for Testing Materials.  For
non-commercial purposes these associations note that the exact conversion
factor is 1.05505585262 Gigajoules per Dekatherm.)  For purposes of this
tariff and associated Service Agreements, MMBtu and Dth are considered
synonymous.
