2.3 Heating Value: Shipper shall not be required to accept

natural gas having a heating value of less than 967 Btu per

cubic foot.


2.4 Objectional Matter: The gas delivered:


(a) Shall be commercially free from particulates or other

solid or liquid matter which might interfere with its

merchantability or cause injury to or interference

with proper operation of the lines, regulations,

meters and other equipment of Shipper.


(b) Shall contain less than one grain of hydrogen sulfide

per one hundred (100) cubic feet of gas.


(c) Shall not contain more than twenty (20) grains of

total sulfur per one hundred (100) cubic feet.



3.1 Unit of Measurement: The transportation unit of gas

received and delivered by Transporter shall be a dekatherm.


3.2 Determination of volume and total heating value: The

volume and the total heating value of gas received and

delivered by Transporter shall be determined as follows:


(a) The unit of volume, for the purpose of measurement,

shall be one (1) cubic foot.


(b) The total heating value of the gas per cubic foot

shall be determined for any day or month by taking the

average of the heating values as recorded each day by

a calorimeter or as determined by chromatographic

analysis of a sample of gas collected daily or any

other method mutually agreed upon.


(c) Dekatherms delivered shall be determined by

multiplying the Mcf delivered by the ratio of the Btu

per cubic foot delivered to 1,000. For the purposes

of this determination the specific gravity and

heating value shall be determined at approximately

the same time.


(d) The temperature of the gas passing through the meters

shall be determined for any day by the continuous use

of a recording thermometer so installed that it may
