Section 4



4. Measurement Procedures and Equipment


4.1 The unit of measurement of Gas for all purposes shall be

Dekatherm. The volumetric measurement base shall be 1 cubic foot

of Gas at a pressure base of 14.73 pounds per square inch

absolute, at a temperature base of 60 degrees Fahrenheit, and

without adjustment for water vapor.


4.2 Any measurement data rebuttal period shall begin with the

interested party issuing a written notification that a

measurement dispute exists. These disputes will apply to

measurement errors that involve quantities that Gulf Crossing has

direct custody transfer responsibilities over, as well as volumes

measured by other companies that have been audited by Gulf

Crossing. Provided, further nothing will prevent Gulf Crossing

or a Customer from going beyond six months if a meter error is

discovered and the date of the error can be established with

reasonable certainty.


4.3 For the purpose of measurement, calculation and meter

calibration, the average absolute atmospheric (barometric)

pressure shall be 14.73 pounds per square inch absolute.


4.4 The temperature of the Gas shall be determined at the points of

measurement by means of a properly installed temperature

transmitter of standard manufacture determined by Gulf Crossing

in exercise of its reasonable judgment to be installed in

accordance with the recommendations contained in ANSI/API 2530

First Edition (Orifice Metering of Natural Gas), including any

subsequent amendments or revisions which meet generally accepted

industry standards and practices and are acceptable to Gulf

Crossing and Customer. The arithmetic average of Hourly

temperatures for each Day shall be used in computing temperatures

of the Gas during such Day. In the event electronic computer

measurement is used, average daily temperature will be computed

as a running average of data determined during each computer
