2.6 Measurement Equipment (Continued)

(e) New Measurement Techniques. If, at any time during the term

hereof, a new method or technique is developed with respect to

gas measurement or the determination of the factors used in

such gas measurement, such new method or technique may be

substituted by Transporter in exercise of its reasonable

judgment. Transporter shall promptly inform all Shippers of

any new technique adopted.

(f) Calibration and Test of Meters. The accuracy of all measuring

equipment shall be verified by Transporter at reasonable

intervals, and if requested, in the presence of

representatives of Shipper, but neither Shipper nor

Transporter shall be required to verify the accuracy of such

equipment more frequently than once in any 30-Day period. If

either Party at any time desires a special test of any

measuring equipment, it will promptly notify the other, and

the Parties shall then cooperate to secure a prompt

verification of the accuracy of such equipment.

(g) Correction of Metering Errors. If, upon test, the measuring

equipment is found to be in error by not more than one percent

(1%), previous recordings of such equipment shall be

considered accurate in computing deliveries, but such

equipment shall be adjusted at once to record accurately. If,

upon test, the measuring equipment shall be found to be

inaccurate by an amount exceeding one percent (1%), at a

recording corresponding to the average hourly rate of flow for

the period since the last preceding test, then any previous

recordings of such equipment shall be corrected to zero error

for any period that is known definitely or agreed upon. In

case the period is not known or agreed upon, such correction

shall be for a period equal to the lesser of one-half of the

time elapsed since the date of the last test or sixteen Days.
