GENERAL TERMS AND CONDITIONS

4.5 Correction of metering errors - failure of meters: In the event a

meter is out of service or registering inaccurately, the volume of

gas delivered shall be determined:

(a) by using the registration of any check meter or meters, if

installed and accurately registering; or, in the absence of

(a);

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

ascertainable by calibration, tests, or mathematical

calculation; or, in the absence of both (a) and (b), then;

(c) by estimating the quantity of delivery by deliveries during

periods under similar conditions when the meter was registering

accurately.

4.6 Correction of metering errors - adjustments: A measurement data

correction shall become a prior period adjustment (PPA) after the

fifth (5th) business day following the delivery month. Measurement

data corrections shall be processed within six (6) months from the

delivery month, unless (i) Transporter and Shipper mutually agree

otherwise or (ii) the correction is the result of a deliberate

omission or misrepresentation by a Party or a mutual mistake of fact.

In all instances where a correction is made, Shipper or Transporter,

as applicable, has 90 days to dispute the correction. In the case of

corrections made under (i) or (ii) above, the period for resolving

corrections will be tolled until the correction is settled.

4.7 Preservation of metering records: Transporter and Shipper shall each

preserve for a period of at least one year all test data, charts and

other similar records.
