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

determined from read-outs of continually operating measurement

instruments. The method shall consist of one or more of the



(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



(c) Tests shall be made to determine the total sulfur, hydrogen

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 satisfactory to the parties. Tests shall be made frequently

enough to ensure that the gas is conforming continuously to the

quality requirements.


9.4 Failure to Conform to Specifications. If the gas offered for

delivery to Transporter at the Receipt Point(s) or made available to

or on behalf of Shipper at the Delivery Point(s) by Transporter shall

fail at any time to conform to any of the specifications set forth

in Sections 9.1, 9.2 or 9.3, then the party receiving such gas (the

"receiving party") shall notify the other party (the "tendering

party') of such deficiency and thereupon the receiving party may at

its option refuse to accept such gas pending correction by the

tendering party. Upon the tendering party's failure promptly to

remedy any deficiency the receiving party may accept such gas and may

make changes necessary to bring such gas into conformity with such

specifications, and the tendering party shall reimburse the receiving

party for any reasonable expense incurred by it in effecting such

changes. In no event shall the failure of any gas offered for

delivery to Transporter by Shipper or for Shipper's account to
