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
