General Terms and Conditions

(iii) Carbon Dioxide. Not more than two percent by volume of

carbon dioxide;

(iv) Entrained Water. Not more than four pounds of entrained

water per 1,000,000 cubic feet, at a pressure base of 800

pounds per square inch and a temperature of 15 degrees

Fahrenheit as determined by a dew-point apparatus approved

by the Bureau of Mines or such other apparatus as may be

mutually agreed upon;

(v) Polychlorinated Biphenyl (PCB). No measurable quantity of

PCB utilizing the best available measurement technology;

and

(vi) Hydrocarbon Dew Point. Less than 15 degrees Fahrenheit at

800 pounds per square inch.

(d) Temperature. The Natural Gas shall have a temperature of not more

than 110 degrees Fahrenheit.

9.3 Quality Tests.

(a) Upon reasonable notice from Transporter, Shipper shall conduct or

cause to be conducted such tests as are required to determine

whether Gas tendered by Shipper to Transporter is in conformance

with the specifications set forth in this Section 9. Upon

reasonable notice from Shipper, Transporter shall conduct such

tests as are required to determine whether Gas redelivered by

Transporter to Shipper at the Delivery Point(s) is in conformance

with the specifications set forth in this Section 9.

(b) The gross heating value of Gas delivered hereunder shall be

determined from read-outs of continually operating measurement

following:

(1) calorimeter;

(2) gas chromatograph;

(3) any other method mutually agreed upon by the parties.

Measurement of gross heating value with the calorimeters shall

comply with the standards set forth in the American Society for

Testing and Materials' ASTM D 1826-83 or any subsequent revisions.

Analysis of Gas with gas chromatographs shall comply with the

standards set forth in ASTM D 1945-81 or any subsequent revisions.

Calculation of the gross heating value from compositional analysis

by gas chromatography shall comply with the standards set forth in

ASTM D 3588-81 or any subsequent revisions. Transporter or its

Agent shall calibrate and maintain the gross heating value

measurement device at intervals as agreed upon by Transporter and

Shipper. Shipper shall have access to Transporter's devices and

shall be allowed to inspect the devices and all charts or other

records of measurement at any reasonable time.

sulfide, carbon dioxide and oxygen content of the Gas, by approved

standard methods in general use in the gas industry, and to

determine the hydrocarbon dew point and water vapor content of such

Gas by methods satistory to the parties. Tests shall be made

frequently enough to ensure that the Gas is conforming continuously

to the quality requirements.
