(Continued)

15. Measurements

(a) Measurement Unit

The measurement unit of the natural gas delivered by

Seller shall be one (1) Dekatherm (dt).

(b) Determination of Volume and Heating Valve

The volume and the heating value of the natural gas

delivered by Seller shall be determined as follows:

(1) The unit of volume for the purpose of measurement

shall be one (1) Mcf of gas at a temperature of

sixty (60) degrees Fahrenheit and at an absolute

pressure of fourteen and seventy-three hundredths

(14.73) pounds per square inch.

(2) The pressure and temperature of the gas passing

through the meters shall be determined by the use of

electronic measurement equipment or other recording

device. The instantaneous measurements from the

electronic measurement equipment or the average of

the pressure and temperature recorded each Day shall

be used in computing gas volumes. For both

reporting and calculation purposes pressure base

conversion factors shall be reported to not less

than six (6) decimal places.

(3) The specific gravity of the gas delivered by Seller

on any Day shall be fixed at a value, which is a

representative value of that which is reported to

Seller by the interconnecting upstream pipeline(s).

(4) The deviation of the natural gas from Boyle's and

Charles' Law shall be that determined in accordance

with, but not limited to, the published

recommendations of the American Gas Association and

the American National Standards Institute as

Seller deems to be in accordance with accepted

industry practice. The amount of nitrogen and

carbon dioxide contained in gas for the purpose of

determining the deviation factors shall be derived

from that which is reported to Seller by the

interconnecting upstream pipeline(s).
