4. MEASUREMENT OF GAS (Continued)

 

4.8 Adjustment of Inaccuracies. (Continued)

equipment found inaccurate shall be immediately restored by the

operating party as closely as possible to a condition of accuracy. If

the measurement equipment is out of service or out of repair for any

reason so that the amount of gas delivered cannot be estimated or

computed from the reading thereof, the amount of gas delivered through

the period such meter is out of service or out of repair shall be

estimated and agreed upon by the Transporter and Receiving Party upon

the basis of the best data available using the first of the following

methods which is feasible:

(a) by using the registration of the other party's check meter if

installed and accurately registering; or

(b) by correcting the error if the percentage of error is

ascertainable by calibration, test or mathematical calculation; or

(c) by estimating the quantity of deliveries by comparison with

deliveries during preceding periods under similar conditions when

the meter was registering accurately.

 

4.9 Correction of Volume Calculation Error. If, upon inspection and

verification, any volume calculation error shall result in a daily

volume inaccuracy exceeding two (2) percent, then the inaccuracy shall

be corrected to zero error. Such errors shall be adjusted within

thirty (30) days following verification by seller and buyer, however,

in no event shall inaccuracies less than two (2) percent daily or 100

MMBtus monthly be corrected. No correction shall extend back more than

one year from the date such error was identified.

 

4.10 Records Preservation. Each party shall preserve all test and

measurement data, charts or similar records for a period of at least

one (1) year or such other periods as shall be required under Part 225

of the Commission's regulations or the lawful requirements of any other

governmental body, Federal or State, prescribing longer retention
