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.

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.
