3.4 Calibration and Test of Measurement Equipment - Each party

shall have the right to have representatives present at the

time of any installing, cleaning, changing, repairing,

inspecting, testing, calibrating or adjusting done in

connection with the other party's measuring equipment,

including calorimeters, used in the measurement of deliveries

of gas.


The accuracy of the measuring equipment, including

calorimeters, shall be verified at reasonable intervals but

not more frequently than once in any thirty (30) day period.

In the event either party shall notify the other that it

desires a special test of said measuring equipment or of the

check measuring equipment, as the case may be, the parties

shall cooperate to secure prompt verification of the accuracy

of such equipment. Each party shall give to the other party

sufficient advance notice of the time of all such special

tests so that the other party may conveniently have its

representatives present.


3.5 Charts and Records - Upon request of either party, the other

shall submit the records and charts from its measuring

equipment used in the measurement and billing of gas,

including records resulting from electronic flow measurement,

chartless custody transfers or any other improved measurement

technology, together with calculations therefrom, for

inspection and verification, subject to return within thirty

(30) days after receipt.


The parties 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.


3.6 Correction of Metering Errors - If, upon test, the 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.
