GENERAL TERMS AND CONDITIONS

(continued)

measuring equipment shall be made at the expense of Transporter,

except that the Shipper shall bear the expense of additional

tests made at its request if the inaccuracy is found to be two

percent (2%) or less.

3.4 Correction and Adjustment: If at any time any of the measuring

equipment is registering inaccurately by an amount less than two

percent (2%), previous readings shall be considered correct. If

the inaccuracy exceeds two percent (2%) at a reading correspond-

ing to the average hourly rate of flow, the previous readings of

such equipment shall be corrected to zero error for any

inaccurate period definitely known or agreed upon, or if not so

known or agreed upon, for a period of one-half (1/2) of the

elapsed time since the last test not to exceed a correction

period of thirty (30) days. If the measuring equipment is out of

service, the volume of gas delivered during such period shall be

determined:

(a) By using the data recorded by any check measuring equipment

accurately registering; or

(b) If such check measuring equipment is not registering accur-

ately, but the percentage of error is ascertainable by a

calibration test, by using the data recorded, corrected to

zero error; or

be used, by estimating the quantity delivered by reference

to deliveries under similar conditions during a period when

the equipment was registering accurately.
