The measurement and test of quality of gas delivered hereunder shall be

governed by the following:


3.1 Except as provided by law, all fundamental constants, observations,

unless otherwise specified herein, be in accordance with the standards

prescribed in Gas Measurement Committee Report No. 3, American Gas

Association, including the appendix thereto, as published September

1969, and any subsequent amendments thereof.


3.2 The unit of volume for purposes of measurement (other than of heat

content) shall be one (1) cubic foot of gas at a temperature of sixty

(60) degrees Fahrenheit and at a pressure base of fourteen and

seventy-three hundredths (14.73) psia. All measurements of gas shall

be determined by calculation into terms of such unit. All quantities

given herein, unless otherwise expressly stated, are in terms of such



3.3 Gas Transport shall own, maintain and operate, all measurement

facilities or cause same to be owned, maintained and operated, at the
