3.6. Prior Period Adjustments


Pursuant to NAESB Standards 2.3.7, 2.3.11, 2.3.12, 2.3.13, 2.3.14: The cutoff

for the closing of measurement is five (5) business days after the business month.

For treatment of measurement prior period adjustments, treat the adjustment by

taking it back to the transportation month. A meter adjustment becomes a prior

period adjustment after the fifth (5th) business day following the business month.

For reporting measurement prior period adjustments, report it with the restated

line item with new total quantity for the day and the month. Estimate missing or

late measurement data and treat actual as a prior period adjustment, with the

measuring party to provide the estimate. Measurement data corrections should be

processed within six (6) months of the transportation 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 shall not otherwise be diminished by this standard.

Gross Heating Value of Gas delivered and ready verification of the accuracy of
