GENERAL TERMS AND CONDITIONS

Section 3

(Continued)

3.7 Determination of Flowing Temperature - When orifice meters are used

in conjunction with charts, the temperature of the gas flowing

through the meter or meters shall be determined by the continuous

use of a recording thermometer installed so that it will properly

record the temperature of the gas flowing through the meter or

meters. The average of the temperature recorded during a period

shall be used in computing the volumes of gas for that period.

Temperature shall be determined to the nearest whole degree in

Fahrenheit.

When positive or turbine meters are used, the flowing temperature

of the gas shall be assumed to be sixty (60) degrees Fahrenheit

and no correction shall be made for any variation therefrom;

provided, however, Gulf South shall have the option of installing

or causing to be installed a recording thermometer, and if Gulf

South exercises such option, correction shall be made for each

degree variation in the average flowing temperature for each meter

recording.

3.8 Determination of Specific Gravity - The specific gravity (relative

density) of the gas flowing through the meter or meters shall be

determined by a chromatograph, continuous sampler, spot sample, or

gravitometer, which method shall be selected by Gulf South, and

shall meet generally accepted industry standards and practices.

The arithmetical average of specific gravity recorded during

periods of flow by a chromatograph or gravitometer shall be

considered as the specific gravity of the gas delivered during

such period.

In the event a spot sample is taken or a continuous gas sampler is

used, the specific gravity of the composite sample so taken shall

be considered as the specific gravity of the gas delivered during

an applicable measurement period as determined by Gulf South. All

specific gravity determinations made with a chromatograph shall

use physical gas constants for gas compounds as outlined in the

1985 edition of A.G.A. Report No. 3 (ANSI/API 2530, GPA 8185) on

"Orifice Metering of Natural Gas" including any subsequent

amendments or revisions acceptable to Gulf South, and shall meet

generally accepted industry standards and practices. Specific

gravity shall be determined to the nearest one thousandth (0.001).
