4.1 Transporter's Measuring Equipment:


Gas delivered to Transporter and by Transporter to or for the account of Shipper shall be

measured by meters installed, operated, and maintained by Transporter, or such meters as

Transporter causes to be installed, operated, and maintained, equipped to record daily and

hourly deliveries. Measurement data may be recorded using electronic recorders or

instantaneous flow computations in electronic flow computers, and shall be so recorded

at the Receipt Point(s) and Delivery Point(s). Orifice meter installations shall conform to

the recommendations for design and installation contained in AGA Report No. 3, as

revised September 1985, and as such report may hereafter be further revised. Positive

displacement meter installation shall conform to generally accepted engineering practices

in the industry.


4.2 Testing Measuring Equipment:


Transporter shall test its meters, installed as provided in Section 4.1 above, at intervals of

a maximum of sixty (60) days or such lesser time as may be required by the Minerals

Management Service. Transporter shall test thermometers, gravitometers, calorimeter,

chromatographs and other equipment installed as provided in Subsections 3.2(c), and

3.2(d) above, at intervals of a maximum of thirty (30) days or such lesser time as may be

required by the Minerals Management Service. Transporter will notify Shippers in time

to permit Shipper to witness at its expense such test if Shipper so elects.


4.3 Correction of Metering Errors:


If Transporter's measurement equipment installed under Section 4.1 above or any other

equipment installed under Subsections 3.2(c) and 3.2(d) above is found to be inoperative

or inaccurate, such equipment shall be adjusted to register correctly, and the amount of

error shall be determined by the most accurate method feasible. If the inaccuracy shall

have resulted in an error of more than 1% in the measurement of gas, then the calculated

deliveries of gas shall be adjusted to compensate for such error. Such adjustment shall be

made for such period of inaccuracy as may be definitely known. If the period of

inaccuracy shall not be definitely known, then such adjustment shall be made for the last

half of the period (but not exceeding 15 days) between the time the metering equipment

was adjusted to register correctly and the date of the last previous meter test. If for any
