19. MEASUREMENTS AND TESTS FOR DELIVERY OF NATURAL GAS

The volumes of Natural Gas received or delivered through a meter or meters shall be

determined in accordance with the provisions set forth in this Section.

(a) Measurement Unit. The Measurement Unit shall be one Dekatherm (Dth) of Natural Gas

and shall be calculated by multiplying the volume delivered in Mcf by a fraction, the

numerator of which is the Heating Value and the denominator of which is 1,000.

(b) Volumetric Measurement Base. The volumetric measurement base shall be one cubic foot

of Natural Gas at a pressure base of fourteen and seventy-three one-hundredths (14.73)

pounds per square inch absolute, a temperature base of sixty degrees (60°) Fahrenheit

(519.67 R Absolute), and dry. For gas volumes reported in cubic meters, 101.325 kPa,

15 degrees C, dry.

assumed to be fourteen and four-tenths (14.4) pounds per square inch, irrespective of

actual elevation or location of the delivery point above sea level or variations in

actual barometric pressure from time to time.

(d) Temperature. The temperature of the Natural Gas shall be determined at Operator's

option:

(1) where Electronic Measurement equipment is provided, by continuous application

of instantaneous temperature measurements from one or more of the meters at a

measuring station, or by contemporaneous application of the arithmetic or other

average of the temperature record from one or more of the meters for the time

during which gas is flowing;

(2) where Electronic Measurement equipment is not provided,

(i) where an instrument which measures and records the temperature of the

flowing gas is installed, by contemporaneous application of the arithmetic

or other average of the hourly or daily temperature record from one or

more of the meters at a measuring station, or

(ii) where an instrument which measures and records the temperature of the

flowing gas is not installed, by contemporaneous application of the

temperature as read from established tables of monthly averages for the

point of measurement; or

(3) by any other method or methods mutually agreed upon by Operator and Buyer.

(e) Static Pressure. The static pressure of the Natural Gas shall be determined at

Operator's option:

(1) 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;

(2) 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

(3) by any other method or methods mutually agreed upon by Operator and Buyer.
