SECTION 1

General rules

Approval of modifications of the monitoring plan
Article 15
1
The operator or aircraft operator shall notify any proposals for modification of the monitoring plan to the competent authority without undue delay.
However, the competent authority may allow the operator or aircraft operator to notify, by 31 December of the same year, modifications of the monitoring plan that are not significant within the meaning of paragraph 3.
2
Any significant modification of the monitoring plan within the meaning of paragraphs 3 and 4 shall be subject to approval by the competent authority.
Where the competent authority considers a modification not significant, it shall inform the operator or aircraft operator thereof without undue delay.
3
Significant modifications to the monitoring plan of an installation shall include the following:
a
changes of the category of the installation;
b
notwithstanding Article 47(8), changes regarding whether the installation is considered an installation with low emissions;
c
changes to emission sources;
d
a change from calculation-based to measurement-based methodologies, or vice versa, used to determine emissions;
e
a change in the tier level applied;
f
the introduction of new source streams;
g
a change in the categorisation of source streams — between major, minor or de-minimis source streams;
h
a change of the default value for a calculation factor, where the value is to be laid down in the monitoring plan;
i
the introduction of new procedures related to sampling, analysis or calibration, where the changes of those procedures have a direct impact on the accuracy of emissions data;
j
the implementation or adaption of a quantification methodology for emissions from leakage at storage sites.
4
Significant changes to the monitoring plans of an aircraft operator shall include:
a
with regard to the emission monitoring plan:
1. a change of tiers related to fuel consumption;
2. a change of emission factor values laid down in the monitoring plan;
3. a change between calculation methods as laid down in Annex III;
4. the introduction of new source streams;
5. a change in the categorisation of source streams where a minor source stream changes to a major source stream;
6. changes in the status of the aircraft operator as a small emitter within the meaning of Article 54(1);
b
with regard to the tonne-kilometre data monitoring plan:
1. a change between a non-commercial and commercial status of the air transport service provided;
2. a change in the object of the air-transport service, the object being passengers, freight or mail.
