GENERAL TERMS AND CONDITIONS

(continued)

 

5.2 Retention of Records - Buyer or Shipper and Western

respectively, shall preserve all test data, charts and

other required data pertaining to the measurement of gas by

their respective measurement equipment for a period of

three (3) years or such other period or periods as may be

prescribed with respect to them by regulatory bodies having

jurisdiction.

 

 

6. METERING ERRORS:

 

6.1 Correction of Metering Errors - If, upon test, Western's

measuring equipment is found to be in error by not more

than two percent (2%), previous recordings of such

equipment shall be considered accurate in computing

deliveries, but such equipment shall be adjusted at once to

record accurately. Errors exceeding two percent (2%) at a

recording corresponding to the average hourly rate of flow

for the period since the last preceding test will be

corrected. Previous recordings of such equipment shall be

corrected to zero error for any period which is known

definitely or agreed upon. If the period is not known or

agreed upon, the correction shall be made for a period of

one-half of the time elapsed since the last test but shall

not exceed sixteen (16) days.

 

6.2 Failure of Meters - In the event a meter is out of service

or registering inaccurately, the volume of gas delivered

shall be determined:

 

(a) By using the registration of any check meter or

meters, if installed and accurately registering; or,

in the absence of (a),

 

(b) By correcting the error if the percentage of error is

ascertainable by calibration, tests, or mathematical

calculations; or in the absence of both (a) and (b),

then

 

(c) By estimating the quantity of delivery during a period

under similar conditions when the meter was

registering accurately.
