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 deliveries of gas under the transportation

contract. 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 ten Days after receipt thereof.

4.3 Care Required: Any installation of measuring equipment applying

to or affecting deliveries of gas shall be made in such manner as

maintenance and operation of pressure-regulating equipment so as

to prevent any inaccuracy in the determination of the quantity of

gas delivered under service agreements.

equipment shall be verified at reasonable intervals and, if

requested, in the presence of representatives of the other

party, but neither party shall be required to verify the

accuracy of such equipment more frequently than once in any

thirty-day (30) period. In the event either party shall

notify the other that it desires a special test of any

measuring equipment, the parties shall cooperate to secure a

prompt verification of the accuracy of such equipment. The

expense of any such special test, if called for, shall be

borne by the requesting party if the measuring equipment

tested is found to be in error not more than two percent

(2%).
