GENERAL TERMS AND CONDITIONS

(Continued)

3. MEASUREMENT

3.1 Unit of Measurement and Metering Base. The

volumetric measurement base shall be one (1)

cubic foot of natural gas at a pressure base of

fourteen and seventy-three hundredths (14.73)

psia, a temperature base of sixty degrees (60ø)

Fahrenheit, and without adjustment for water

vapor content. Except as otherwise provided by

law, the volume of natural gas delivered at the

point of receipt and at the point of delivery

hereunder shall be computed in accordance with

the standards prescribed in Gas Measurement

Report No. 3 of the American Gas Association,

dated April 1955, as revised September 1969, and

from time to time amended, supplemented or

superseded. All quantities of natural gas given

herein, unless otherwise stated, are in terms of

the unit of volume set forth above in this

Section 3.1.

3.2 Atmospheric Pressure. For the purpose of

measurement, calculations and meter calibration,

the average absolute atmospheric (Barometric)

pressure for each point of receipt and point of

delivery shall be as specified in an executed

Service Agreement irrespective of variations in

natural atmospheric pressure from time to time.

3.3 Temperature. The temperature of the natural gas

shall be determined at the point of measurement

by means of recording thermometers of standard

manufacture acceptable to Transporter and Shipper

to be installed in accordance with the recommen-

dations contained in Gas Measurement Report

No. 3, as aforesaid, and the arithmetic average

of hourly temperatures of day shall be used

in computing temperatures of the natural gas

during each day.

3.4 Specific Gravity. The specific gravity of the

natural gas shall be determined at the point of

measurement by one of the following methods:

(a) By means of a properly installed recording

gravitometer of standard manufacture

acceptable to Transporter and Shipper, or

(b) By use of a portable specific gravity

balance of standard manufacture acceptable

to Transporter and Shipper. Such deter-

mination to be made at least once every six

(6) months, or

(c) By means of a calculated specific gravity

derived from a gas chromatograph

determination.
