2. MEASUREMENT (Continued)


2.8 Supercompressibility. The measurement hereunder shall be corrected

for deviation from Boyle's law in accordance with AGA Report No. 8.


2.9 Measuring Equipment. Unless otherwise agreed, Transporter will

install, maintain, or operate or cause to be installed, maintained

and operated, measuring stations equipped with flow meters and other

necessary metering and measuring equipment by which the volumes of

Gas received and Delivered hereunder shall be determined. Shipper

may install check measuring equipment at its own cost and expense,

provided such equipment shall be so installed as not to interfere

with the operations of Transporter. Transporter 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 of electronic computer components and/or mechanical

recording instruments thereof and the changing of charts shall be

done only by the equipment owner or such owner's representative,

unless otherwise agreed upon. Both Transporter and Shipper 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 Transporter 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 their owner, but upon request, each

will submit within 10 days to the other its records and charts,

together with calculations therefrom, for inspection, subject to

return within 30 days after receipt thereof. The measurement

equipment of Shipper shall be for check purposes only and, except as

expressly provided in the applicable Agreement, shall not be used in

the measurement of Gas for purposes of the Agreement.


2.10 Orifice Meters. Orifice meters shall be installed and Gas volumes

computed in accordance with the standards prescribed in AGA Report

No. 3 "Orifice Metering of Natural Gas".


2.11 Electronic Flow Computers. It is recognized that electronic or other

types of flow computers have been developed that permit the direct

computation of Gas flows without the use of charts. Where the

substitution of these devices is deemed acceptable by Transporter in

exercise of its reasonable judgment, their use for custody transfer

will be permitted.
