GENERAL TERMS AND CONDITIONS

(Continued)

 

in calculating gas delivered for the day on which the test is made

and all following days until the next test is made.

 

The calculations (for Btu) shall be based on dry gas if the gas at

the measurement points contain less than 5 pounds of water per

MMcf. If the gas at the measurement points contains more than 5

pounds of water per MMcf, the appropriate factor will be applied

to the Btu calculations to correct for water content in excess of

5 pounds per MMcf.

 

After consideration is given for Shipper's fuel gas requirements,

the difference between Btu's received by TransColorado and Btu's

delivered to Shipper shall be deemed unaccounted-for gas. Shipper

shall provide its proportionate share of unaccounted-for gas.

 

10.5 Supercompressibility. The measurement of gas shall be corrected

for deviation from Boyle's Law at the pressures and temperatures

under which gas is measured by use of the calculation appearing in

the manual entitled "PAR Research Project NX-19, Extension of

Range of Supercompressibility Table," AGA Catalog No. 48/PR

published by the American Gas Association in 1963 as supplemented

or amended from time to time. Inert content of the metered gas

stream used in the Formula NX-19 calculations shall be determined

by a chromatographic analysis using spot sampling when deliveries

begin and thereafter by (i) chromatographic analysis not less than

semiannually, (ii) continuous sampling or by continuous computer

input at each of the points where the gas is received and

delivered.

 

10.6 Measuring Equipment. Unless otherwise agreed upon, TransColorado

will install, maintain and operate or cause to be installed,

maintained and operated measuring stations equipped with flow

meters and other necessary metering and measuring equipment by

which volumes of gas received and equivalent volumes delivered

shall be determined. Shipper may install check measuring

equipment at its own cost and expense; provided such equipment

shall be installed in a manner not to interfere with the

operations of TransColorado.

 

TransColorado and Shipper, in the presence of each other, shall

have access to the other's measuring equipment at all reasonable

times but the reading, calibrating and adjusting electronic

computer components and/or mechanical
