5.1 Determination of Quantity


The quantity of Natural Gas received and delivered by Transporter

to Shipper or for Shipper's account hereunder shall be measured

according to Boyle's and Charles' Laws for the measurement of

Natural Gas under varying pressures and temperatures with

deviations therefrom as provided in paragraph 5.1(i) below and

shall be determined as follows.


(a) The unit of measurement for the purpose of service under any

of Transporter's Rate Schedules shall be one (1) Dth. The

number of Dth's delivered shall be determined by multiplying

the number of Cubic Feet of Natural Gas received or

delivered, measured on the measurement basis hereinafter

specified, by the Total Heating Value of such Natural Gas,

in Btu's per Cubic Foot, and by dividing the product by one

(1) million (1,000,000).


(b) When Natural Gas is delivered at a pressure different from

14.73 psia, then for the purpose of measurement hereunder,

such quantities of Natural Gas shall be corrected to a

pressure of 14.73 psia. The unit of quantity for the

purposes of measurement shall be one (1) Cubic Foot of

Natural Gas at a temperature of 60 degrees Fahrenheit, at a

pressure of 0.33 psig gauge and an atmospheric pressure of

14.4 psia, resulting in pressure of 14.73 psia. The factor

used to correct to the pressure base of 14.73 pounds per

square inch absolute shall be stated to at least the sixth

decimal place.


(c) The unit of weight for the purpose of measurement hereunder

shall be one (1) pound mass of Natural Gas.
