GENERAL TERMS AND CONDITIONS

(Continued)

 

5.2 Testing Measuring Equipment:

 

COMPANY shall test its meters, installed as provided in Section 5.1 above,

at reasonable intervals. COMPANY shall test thermometers, gravitometers,

calorimeters, chromatographs and other equipment installed as provided in

Sections 3.1(f), 4.2(c), and 4.2(d) above, at reasonable intervals. COMPANY

will notify SHIPPER in time to permit SHIPPER to witness at its expense

such test if SHIPPER so elects. Measuring equipment shall be subject to

check tests and inspection by SHIPPER at its expense, on notice, at all rea-

sonable times.

 

In the event SHIPPER'S or Receipt Point Operator's or Downstream Operator's

pipeline or production facilities go offline for more than twenty-four (24) hours

due to destruction or damage or the potential for destruction or damage of such

upstream or downstream facilities, COMPANY shall have the right to test or

inspect its equipment for damage within a reasonable period of time prior to

allowing the point operator to resume service.

 

5.3 Correction of Metering Errors:

 

If COMPANY'S measurement equipment installed under Section 5.1 above

or any other equipment installed under Sections 3.1(f), 4.2(c), and 4.2(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 2% 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 reason the

measuring equipment is out of service or out of repair so that the amount of

gas delivered cannot be ascertained or computed from the readings thereof,

the amount of gas delivered during such period shall be estimated and agreed

upon by the use of the first of the following methods which is feasible: (a) by

using the registration of any check measuring equipment if installed and

accurately registering; (b) by correcting the error if the percentage of error is

ascertainable by calibration, test or mathematical calculation; or (c) by

estimating the quantity of gas delivered by reference to actual deliveries

during preceding periods under similar conditions when the equipment in

question was registering accurately.
