GENERAL TERMS AND CONDITIONS

(continued)

1.8 The term "Btu" shall mean British thermal unit, and is defined as

the amount of heat required to raise the temperature of one pound

of water one (1) degree Fahrenheit from fifty-nine (59) degrees

Fahrenheit to sixty (60) degrees Fahrenheit at a standard

pressure of fourteen and seventy-three hundredths pounds per

square inch absolute (14.70 psia). For reporting purposes, Btu

conversion factors should be reported to not less

than 3 decimal places.

1.9 The term "gross heating value" shall mean the quantity of heat in

Btu's liberated by the complete combustion at constant pressure,

of a cubic foot of gas at a temperature of sixty (60) degrees

Fahrenheit on a water free basis and at an absolute pressure of

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

pressure as the gas, when the products of the combustion are

cooled to sixty (60) degrees Fahrenheit and when the water formed

by combustion is condensed to the liquid state.

1.10 The term "psia" shall mean pounds per square inch absolute.

1.11 The term "psig" shall mean pounds per square inch gauge.

1.12 The term "thermally equivalent" means an equal number of Btu's.

1.13 The term "MMBtu" is equivalent to the term "dekatherm" Dekatherms

shall be the standard unit for nominating, scheduling, invoicing,

and balancing. The number of dekatherms received or delivered

shall be determined by multiplying the number of cubic feet of

gas received or delivered, by the total heating value of such

gas, in British thermal units per cubic foot. Pressure base

conversion factors should be reported to not less than 6 decimal

places. For calculation purposes, not less then 6 decimal places

should be used for both conversion factors. Divide the product

by a million (1,000,000).

2. QUALITY OF GAS:

2.1 Quality Standards: Except as provided herein, the gas which

Shipper delivers hereunder to Transporter and the gas which

Transporter delivers hereunder to Shipper for transport shall be

merchantable gas, at all times complying with the following

quality requirements:

(a) the gas shall be free from objectionable odors, solid

matter, dust, gums and gum-forming constituents, or any

other substance which might interfere with the

merchantability of the gas, or cause injury to or
