GENERAL TERMS AND CONDITIONS (Cont'd)

 

26.5 Static Pressure. The static pressure of the natural gas shall be determined at Transporter's option:

 

(a) where Electronic Measurement equipment is provided, by continuous application of instantaneous

static pressure measurements from one or more of the meters at a measuring station, or by contemporaneous

application of the arithmetic or other average of the static pressure Record from one or more of the meters

for the time during which gas is flowing;

 

(b) where Electronic Measurement equipment is not provided, by contemporaneous application of the

static pressure Record from one or more of the meters at a measuring station, or by contemporaneous

application of the arithmetic or other average of the hourly or daily static pressure Record from one or more

of the meters at a measuring station; or

 

(c) by any other method or methods mutually agreed upon by Transporter and Shipper.

 

26.6 Specific Gravity. The specific gravity (relative density) of the natural gas shall be determined by

gravitometric, chromatographic, or other generally accepted analytical method at Transporter's option:

 

(a)where Electronic Measurement equipment is provided,

 

(1) by contemporaneous application of continuous instantaneous specific gravity

measurements, or by contemporaneous application of arithmetic or other average of the

specific gravity for the time during which gas was flowing,

 

(2) by prospective application of the arithmetic or other average of the specific gravity

Record, or

 

(3) by prospective application of the results of analyses of samples of the gas;

 

(b) where Electronic Measurement equipment is not provided,

 

(1) by contemporaneous application of the arithmetic or other average of the hourly or

daily continuous specific gravity Record,

 

(2) by prospective application of the results of analyses of samples of the gas; or

 

(c) by any other method or methods mutually agreed upon by Transporter and Shipper.
