recordings of such equipment shall be corrected to zero error for any period

which is known definitely, but in case the period is not known or agreed upon,

such correction shall be for a period extending over one-half of the time

elapsed since the date of the last test, not exceeding a correction period of

sixteen days.


6. Correction of metering errors--failure of meters: In the event a meter is out

of service, or registering inaccurately, the volume of gas delivered shall be



(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 calculation, or in the absence of

both (a) and (b);


(c) by estimating the quantity of the delivery by use of deliveries during

periods under similar conditions when the meter was registering

of a request, the requestee will either send the relevant information to the

requestor or will provide the requestor the right to review such information in
