putation of quantities of gas hereunder, is found to be in error

to the extent that it introduces not more than one percent (1%)

measurement error in the individual measurement equipment

affected, previous records of such equipment shall be considered



(B) If, upon test, any such above measurement equipment is found to be

in error, to the extent that it causes the registered or computed

quantities of the instrument(s) so affected to be in error, by an

amount exceeding one percent (1%) at a recording corresponding to

the average hourly rate of flow-through the instrument(s) in the

period since the last preceding test, then any registrations,

integration or computed quantities of such instrument(s) affected

shall be corrected to zero (0) error for any part of the period

since the last test in which such error is known to have existed

or which may be agreed upon by representatives of the parties. In

case the period of such error is not know definitely or agreed

upon, such correction shall be for a period of one-half (1/2) of

the elapsed time since the date of the last test, but not exceed-

ing a correction period of sixteen (16) days where orifice

measurement equipment is used in the computation of quantity and

not exceeding forty-five (45) days where other measurement

equipment is used; and


(C) If no tests have been performed to determine the degree of

inaccuracy, or measurement equipment is out of service, the

quantity of gas shall be estimated:


(1) By using the registration of any existing and agreed upon

check equipment considered by parties concerned to be regis-

tering accurately, or in the absence of such facilities,


(2) By correcting the error, if the quantity or percentage of

error is ascertainable by calibration, test, or mathematical

calculation, or if neither of the two foregoing procedures

are applicable,


(3) By relating the quantity of receipt or delivery to receipts

or deliveries during periods under similar conditions when

the measurement equipment was deemed to have been registering
