j. Shipper shall have access at all reasonable times to measuring

equipment and all other instruments used by Vitco in determining

the measurement and quality of gas delivered hereunder, but the

reading, calibrating and adjusting thereof shall be done only

by employees, agents or representatives of Vitco. The charts

and records shall be kept on file for a period of at least one

(1) year, or for such period of time as may be required by the

Federal Energy Regulatory Commission or other regulatory body

having jurisdiction, for the mutual use of the parties hereto.


k. If at any time of the measuring or testing equipment is found to

be out of service or registering inaccurately, it shall be

adjusted at once to read accurately, within the limits prescribed

by the manufacturer. If such equipment is out of service or

inaccurate by an amount exceeding two percent (2%) at a reading

corresponding to the average rate of flow for the period since

the last preceding test, the previous readings of such equipment

shall be disregarded for any period definitely known or agreed

upon, for a period of sixteen (16) days, or one-half of the

elapsed time since the last test, whichever is shorter. The

volume of gas delivered during such period shall be estimated by

(1) using the data recorded by any check measuring equipment if

installed or registering accurately, (2) by correcting the error

if the percentage of error is ascertainable by calibration, test

or mathematical calculation, or if neither such method is

feasible, or (3) by estimating the quantity or quality delivered

based upon deliveries under similar conditions during a period

when the equipment was registering accurately. No correction

shall be made for recorded inaccuracies of two percent (2%) or



l. Either party may, at its option, install a check meter for

checking the measurement of gas being delivered by the other

party, and same shall be so installed as not to interfere with

the operation of the measurement facilities of the measuring
