GENERAL TERMS AND CONDITIONS

(CONTINUED)

2. MEASUREMENT AND MEASUREMENT EQUIPMENT (continued)

(2) The average absolute atmospheric (barometric)

pressure at each Receipt Point and each Delivery

Point shall be assumed to be 14.7, irrespective of

the actual location or elevation above sea level of

the Receipt Point or Delivery Point or of variations

in actual atmospheric pressure from time to time.

(3) The static pressure and temperature of the Gas at

flowing conditions through a meter and, where

applicable, the differential pressure across the

orifice plate of an orifice meter shall be determined

by means of instruments of standard manufacture

accepted in the industry for these purposes.

(4) The supercompressiblity factor used in computing the

volume of Gas delivered through an orifice meter

shall be determined using the procedures presented in

American Gas Association Transmission Measurement

Committee Report No. 8, entitled "Compressibility

Factors of Natural Gas and Other Related Hydrocarbon

Gases."

(5) The specific gravity of the Gas used in computing the

volume of Gas delivered through a meter shall be

determined at each Receipt Point and at strategic

locations determined by Transporter to be

representative for each Delivery Point by standard

methods accepted in the industry for this purpose.

(6) The compressibility ratio factor "s" used in

computing the volume of Gas delivered through a

turbine meter, an ultrasonic meter, or a positive

displacement meter shall be determined by the

equation s = (Fpv)2, in which "Fpv" is the

supercompressiblity factor determined as described in

subparagraph (4) of this subsection (b).
