GENERAL TERMS AND CONDITIONS

 

13.11 Calibration and Test of Measurement Equipment. Overthrust will

verify the accuracy of all measurement equipment at reasonable intervals.

Overthrust will provide notice of regular inspections and calibrations of

measurement equipment and any routine orifice plate changes to the operators

of the interconnecting facilities, and the operators or other contractually

designated representative of shippers may attend the inspections or plate

changes. Overthrust shall not be required to verify the accuracy of its

equipment more frequently than once in a 90-day period. In the event an

operator of an interconnecting facility or their contractually designated

representative notifies Overthrust that it desires a special test of any of

Overthrust's measurement equipment, the parties shall cooperate to secure

prompt verification of the accuracy of such equipment. Any operator of an

interconnecting facility or their contractually designated representative

requesting such a special test of Overthrust's measurement equipment shall

bear Overthrust's out-of-pocket costs of the test if the equipment is found to

be accurate within two percent (2%).

 

13.12 Correction of Measurement Errors. If any measurement equipment is

found to be inaccurate, the equipment will be adjusted immediately to measure

accurately. If the measurement equipment in the aggregate is found to be

inaccurate by two percent (2%) or more at a recording corresponding to the

average hourly rate of gas flow for the period since the last preceding test,

any payments based upon inaccurate measurement will be corrected at the rate

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

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

for a period extending over one half of the time elapsed since the date of the

last test.

 

13.13 Failure of Measurement Equipment. If any measurement equipment is

out of service or is found registering inaccurately and the error is not

determinable by test, or by previous recordings, receipts or deliveries

through such equipment will be estimated and agreed to by the parties upon the

first of the following methods that is feasible:

 

(a) By correcting the error if the percentage of error is

ascertainable by calibration, special test, or mathematical calculation, or,

in the absence of (a);

 

(b) By using the registration of any check meter or meters, if

installed and accurately registering, or, in the absence of (a) and (b);

 

(c) By estimating the quantity of gas received or delivered

based on receipts or deliveries during preceding periods under similar

conditions when the measurement equipment was registering accurately.
