26.8 Supercompressibility.

(a) The deviation of the natural gas from the Ideal Gas Laws shall be determined:

(1) in accordance with the American Gas Association, Par Research Project NX-19 report,

(b) If the measurement method used by Transporter requires the concentrations of nitrogen and

carbon dioxide, the concentrations of nitrogen and carbon dioxide shall be determined by

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

(1) where Electronic Measurement equipment is provided,

(a) by contemporaneous application of continuous instantaneous measurements of

the concentrations of nitrogen and carbon dioxide, or by contemporaneous application of the

arithmetic or other average of the concentrations of nitrogen and carbon dioxide for the time

during which gas was flowing,

(b) by prospective application of the arithmetic or other average of the

concentrations of nitrogen and carbon dioxide Record, or

(c) by prospective application of the results of analyses of samples of the

gas; or

(2) where Electronic Measurement equipment is not provided,

(a) by the contemporaneous application of the arithmetic or other average of

the hourly or daily concentrations of nitrogen and carbon dioxide, or

(b) by prospective application of the results of analyses of samples of the

gas; or by any other method or methods mutually agreed upon by Shipper and Transporter.
