GENERAL TERMS AND CONDITIONS

(Continued)

new method or technique may be substituted by Transporter in

exercise of its reasonable judgment provided that the new method or

technique reflects generally accepted industry practices.

Transporter shall promptly inform all Shippers of any new technique

adopted.

2.7 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.

2.8 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 between

Transporter and Shipper/Operator. In case the period is not known

or agreed upon by Transporter and Shipper/Operator, such correction

shall be for a period equal to one-half of the time elapsed since

the date of the last test.

2.9 Failure of Measurement Equipment. In the event any measuring

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 shall be estimated and

agreed to by the parties upon the first of the following methods

which is feasible:

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

ascertainable by calibration, special test, or mathematical

calculation.

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

installed and accurately registering.
