GENERAL TERMS AND CONDITIONS (Continued)

4. MEASUREMENT

Determination of Quantity. The quantity of gas delivered 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 (g) below and shall be

determined as follows:

(a) The unit of volume for the purpose of measurement shall be 1,000

cubic feet (Mcf) of gas at a temperature of 60 degrees Fahrenheit

and an absolute pressure of 14.73 pounds per square inch

irrespective of the actual elevation above sea level of the point

of measurement or of variations in barometric pressure.

(b) The unit measurement for the purpose of sales and billing 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 Mcf of gas delivered,

measured on the basis hereinafter specified, by the total heating

value of such gas, in British Thermal Units per cubic foot, as

defined in Section 1 above, and by dividing the product by one

thousand (1,000).

continuous use of a recording thermometer at the delivery point

or as agreed by both parties, and the average temperature of the

gas at the delivery point, as computed by such method, shall be

used in computing the deliveries of gas. If the flowing

temperature of gas is not measured, the flowing temperature shall

be assumed to be 60 degrees Fahrenheit.

(d) The specific gravity of the gas delivered hereunder shall be

determined by the continuous use of a recording gravitometer or

as agreed by both parties and the average specific gravity at the

delivery point, as computed by such method, shall be used in

computing the deliveries of gas. If the Specific Gravity of the

gas is not determined, the Specific Gravity shall be assumed to

be .675.

(e) The volumes of gas delivered hereunder shall be measured by meters

of standard make and the measurement by orifice meter shall be

computed in accordance with the methods prescribed in the Gas

Measurement Committee Report No. 3, Natural Gas Department,

American Gas Association, including the appendix thereto, as now

and from time to time amended or supplemented.
