GENERAL TERMS AND CONDITIONS

(Continued)

gas which would occupy one cubic foot of space when

such gas is at a temperature of 60 degrees Fahren-

heit and at a pressure of 14.73 (psia).

1.8 The term "Mcf" is the abbreviation employed to

denote 1,000 standard cubic feet of gas.

1.9 The term "Btu" is the abbreviation employed to de-

note a British thermal unit.

1.10 The term "MMBtu" is the abbreviation employed to

denote 1,000,000 Btu.

1.11 The term "unit total heating value" means the num-

ber of British thermal units determined on a dry

basis, that are produced by the combustion, at con-

stant pressure of the amount of gas which would

occupy a volume of 1.0 cubic foot at a temperature

of sixty (60o) degrees Fahrenheit and under a

pressure of fourteen and seventy-three hundredths

(14.73) (psia) with air at the same temperature and

pressure as the gas, when the products of combus-

tion are cooled to the initial temperature of the

gas and air and when the water formed by combustion

is condensed to the liquid state.

1.12 The term "quantity of gas" shall mean the number of

units of gas expressed in MMBtu unless otherwise

specified.

1.13 The term "equivalent quantities" shall mean quan-

tities of gas of equal thermal content as deter-

mined by the product of their quantities and heat-

ing values as defined above and in Section 3 of

these General Terms and Conditions, less reductions

in gas quantities due to the quantity of gas con-

sumed as compressor fuel, company use, unaccounted

for, if applicable, and loss due to venting.
