(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 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



(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



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

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 (continued)
