GENERAL TERMS AND CONDITIONS
3.1 Unit of Measure
The unit of measure for gas transported by Transporter shall be a
dekatherm. Dekatherms delivered or received shall be determined
by multiplying the Mcf by a fraction, the numerator of which is
the Btu per cubic foot of gas and denominator of which is 1,000.
3.2 Unit of Volume
The unit of volume shall be one cubic foot of gas at a
temperature of 60 degrees Fahrenheit and an absolute pressure of
14.73 pounds per square inch.
3.3 Atmospheric Pressure
The average absolute atmospheric pressure shall be assumed to be
14.4 pounds to the square inch, irrespective of actual elevation
or location above sea level of the delivery or receipt points or
variations in such actual atmospheric pressure from time to time.
3.4 Temperature of Gas
The temperature of the gas flowing through the meters, when
necessary for computing gas quantities, shall be determined by
the use of a recording thermometer or other temperature measuring
device. The arithmetic average of the temperature recorded each
24-hour day, or so much of the 24 hours as gas has been flowing,
shall be used in computing gas quantities or instantaneous
temperature measurements may be applied to metering instruments
to provide the quantity computation. However, in case of any
small volume transaction, the installation of a thermometer may
be omitted at the election of Transporter and in such case the
temperature of the gas for the purpose of measurement shall be
assumed to be 50 degrees Fahrenheit.
