GENERAL TERMS AND CONDITIONS

 

11. MEASURING EQUIPMENT (continued)

 

11.5 Calibration and Testing of Meters. (continued)

 

If, upon testing, any measuring equipment shall be found to be

inaccurate by an amount exceeding two percent, 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 which is

known definitely but in case the period is not known or agreed upon,

such correction shall be for a period extending over one-half of the

time elapsed since the date of last test, not to exceed a period of

180 days.

 

11.6 (a) [NAESB WGQ Standard 2.3.14] Measurement data corrections should

be processed within six (6) months of the production month, with

a three (3) month rebuttal period. This standard shall not

apply in the case of deliberate omission or misrepresentation or

mutual mistake of fact. Parties' other statutory or contractual

rights will not otherwise be diminished by this standard.

 

(b) [NAESB WGQ Standard 2.3.11] For treatment of measurement prior

period adjustments, treat the adjustment by taking it back to

the production month. A meter adjustment becomes a prior period

adjustment after the fifth business day following the business

month.

 

11.7 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.

 

11.8 Preservation of Metering Records. Transporter and Shipper shall

each preserve for a period of two years all test data, charts and

other similar records created after June 1, 1996.
