GENERAL TERMS AND CONDITIONS

7. MEASUREMENT & MEASUREMENT EQUIPMENT

7.1 Determination of Quantity

The Quantity of Gas received and delivered by Pipeline for Customer's account hereunder

shall be measured according to Boyle's and Charles' Laws for the measurement of Gas

under varying pressures and temperatures with deviations therefrom as provided in

paragraph (I) below and shall be determined as follows:

(A)- The unit of measurement for the purpose of service under any of Pipeline's rate

schedules shall be one (1) Dekatherm (Dth), consisting of one million (1,000,000)

British Thermal Units. The number of Dekatherms delivered shall be determined by

multiplying the number of Cubic Feet of Gas received or delivered, measured on

the measurement basis hereinafter specified, by the Total Heating Value of such

Gas, in British Thermal Units per Cubic Foot, as defined in Section 1 of the

General Terms and Conditions, and by dividing the product by 1 million

(1,000,000).

(B) The unit of quantity for the purpose of measurement shall be 1 Cubic Foot of Gas

at a temperature of 60o Fahrenheit and at an absolute pressure of 14.73 pounds

per square inch.

Gas.

(D) The average absolute atmospheric pressure shall be assumed to be 14.7 pounds per

square inch.

(E) The temperature of the Gas passing through the meters shall be determined by the

use of electronic transducers, recording thermometer or other temperature

measuring devices. The arithmetic average of the temperature recorded each 24-

hour day shall be used in computing Gas quantities or continuous instantaneous

temperature measurements as may be applied to metering instruments to provide the

quantity computation.

(F) The specific gravity of the Gas flowing through the meters shall be determined by

gas chromatographic analysis, continuous recording gravitometer, or continuous or

spot sampling methods, unless otherwise mutually agreed upon by Customer and

Pipeline. The arithmetic average of the specific gravity recorded during each

24-hour day shall be used in computing Gas quantities or continuous instantaneous

specific gravity measurements may be applied to metering instruments to provide

the quantity computation.
