GENERAL TERMS AND CONDITIONS

10. MEASUREMENT (Continued)

Gross heating values and specific gravities determined from

spot samples will be used in calculating gas delivered for the day on

which the test is made and all following days until the next test is made.

10.5 Supercompressibility. All orifice meter volumes shall be

corrected for deviations from the ideal gas laws in accordance with the

applicable American Gas Association reports. Where displacement meters

are used, the square of the orifice meter supercompressibility factor

shall be applied.

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. Operator

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 Operator, 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 recording instruments and the changing of

charts shall be done only by the equipment owner or such owner's

representative, unless otherwise agreed upon.

Both TransColorado and Operator shall have the right to be

present at the time of any installing, reading, cleaning, changing,

repairing, inspecting, testing, calibrating, or adjusting done in

connection with the other's measuring equipment; provided, however,

failure of either TransColorado or Shipper to witness such an operation

shall not affect the validity of such operation in any way.

The records from such measuring equipment shall remain the

property of the party owning the equipment, but within 10 days of a

request, each will submit to the other for inspection its records and

charts, together with related calculations. All records and charts shall

be returned within 30 days after receipt.
