7. Separation, Dehydration and Processing: Transporter at its reasonable

discretion may require that some or all of the gas to be transported be

processed to remove liquid and liquefiable hydrocarbons prior to delivery to

Transporter or may require evidence that satisfactory arrangements have been

made for the removal of liquid and liquefiable hydrocarbons at a separation and

dehydration and/or processing plant on Transporter's system. In the event

separation and dehydration and/or processing is to occur after delivery of

transportation gas to Transporter, Transporter and Shipper shall determine a

mutually agreeable charge for the transportation of liquid and liquefiable





1. Unit of Measurement: The transportation unit of gas received and delivered by

Transporter shall be a dekatherm.


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

for all purposes, including billing by Transporter and payment by Shippers and

OBA Operators, on the basis of the electronic measurement equipment installed

by Transporter at receipt and delivery points, as follows:


(a) The unit of volume, for the purpose of measurement, shall be defined as

one cubic foot (1cf) of gas at a temperature of sixty degrees (60ø)

Fahrenheit, and at a pressure of thirty-three hundredths (.33) pounds per

square inch above an assumed atmospheric pressure of fourteen and four

tenths (14.4) pounds per square inch resulting in a pressure base of

(fourteen and seventy-three hundredths (14.73) pounds per square inch

absolute pressure). One thousand (1,000) cubic feet shall be denoted as

one (1) Mcf.


(b) The total heating value of the gas per cubic foot (Btu/cf) shall be

determined by taking the average of the heating values as determined each

day by a chromatograph or the chromatographic analysis of a collected gas

sample, or any other method mutually agreed upon. The average (flow-

weighted) heating value of the gas per cubic foot (Btu/cf) for a unit of

time shall be determined by the total dekatherm divided by the total Mcf

volume multiplied by 1000.
