Value.

If upon test, any measuring equipment is found to be in error by

not more than

the limits specified above, the previous readings of such

equipment shall be

considered accurate in computing deliveries or receipts of Gas,

but such

equipment shall be adjusted at once to register accurately.

If, for the period since the last test, it is determined for a

recording

corresponding to the average hourly rate of flow for such period

that:

(d) Any measuring equipment shall be found to be inaccurate by

an amount

exceeding 2%, or

(e) Any measuring equipment utilized to determine the relative

density shall

be found to be inaccurate by an amount exceeding 1%, or

(f) Any measuring equipment utilized to determine the Gross

Heating Value

shall be found to be inaccurate by an amount exceeding 0.5%,

then the previous readings of the measurement equipment shall be

corrected to

zero error for any period which can be agreed upon, but if the

period is not

agreed upon, such correction shall be for a period extending over

the last

half of the time elapsed since the date of the last test, not

exceeding a

correction period of 16 days.

Notwithstanding the foregoing, when Transporter and Shipper

mutually agree

that a measurement instrument inaccuracy occurred at a definite

point in time,

an appropriate correction shall be made even though said

inaccuracy is less

than the limits specified in (d), (e) or (f) above.

4.4 Either Transporter or Shipper may install, maintain and

operate at its

own expense, such check measuring equipment as desired, provided

that such

equipment shall be so installed as not to interfere with the

operation of the

other's measuring equipment. Any pressure or volume control

regulators

installed by one party shall be operated so as not to interfere

with the other

party's measuring equipment.

4.5 The measuring equipment so installed by either party,

together with any

building erected by it for such equipment, shall remain the

property of the

party that performed the installation. However, either party

shall have the

right to have representatives present at the time of any

installing, reading,

cleaning, changing, repairing, inspecting, testing, calibrating

or adjusting

done in connection with the other's measuring equipment used in

measuring or

checking the measurement of the delivery of Gas. The records

from such

measuring equipment shall remain the property of their owner, but

upon request

each will submit to the other its records and charts, together

with

calculations therefrom, for inspection and verification, subject

to return

within 30 days after receipt thereof.
