CHAPTER II

VERIFICATION

Data verification
Article 16
1
The verifier shall verify the data in the operator’s or aircraft operator’s report by applying detailed testing of the data, including tracing the data back to the primary data source, cross-checking data with external data sources, performing reconciliations, checking thresholds regarding appropriate data and carrying out recalculations.
2
As part of the data verification referred to in paragraph 1 and taking into account the approved monitoring plan, including the procedures described in that plan, the verifier shall check:
a
for the purposes of verifying an operator’s emission report, the boundaries of an installation;
b
for the purposes of verifying an operator’s emission report, the completeness of source streams and emission sources as described in the monitoring plan approved by the competent authority;
c
for the purposes of verifying an aircraft operator’s emission report and tonne-kilometre report, the completeness of flights falling within an aviation activity listed in Annex I of Directive 2003/87/EC for which the aircraft operator is responsible as well as the completeness of emission data and tonne-kilometre data respectively;
d
for the purposes of verifying an aircraft operator’s emission report and tonne-kilometre report, the consistency between reported data and mass and balance documentation;
e
for the purposes of verifying an aircraft operator’s emission report, the consistency between aggregated fuel consumption and data on fuel purchased or otherwise supplied to the aircraft performing the aviation activity;
f
the consistency of the aggregated reported data in an operator’s or aircraft operator’s report with primary source data;
g
where a measurement based methodology referred to in Article 21(1) of Regulation (EU) No 601/2012 is applied by an operator, the measured values using the results of the calculations performed by the operator in accordance with Article 46 of that Regulation;
h
the reliability and accuracy of the data.
3
For the purposes of checking the completeness of flights referred to in point (c) of paragraph 2, the verifier shall use an aircraft operator’s air traffic data, including data collected from Eurocontrol or other relevant organisations which can process air traffic information such as that available to Eurocontrol.
