      4. (iv)

         changes in the status of the aircraft operator as a small emitter within the meaning of Article 55(1) or with regard to one of the thresholds provided by Article 28a(6) of Directive 2003/87/EC;

3. (3)

   Article 49 is replaced by the following:

   Article 49Transferred CO₂

   1

   The operator shall subtract from the emissions of the installation any amount of CO₂ originating from fossil carbon in activities covered by Annex I to Directive 2003/87/EC that is not emitted from the installation, but:

   a

   transferred out of the installation to any of the following:

   1. (i)

      a capture installation for the purpose of transport and long-term geological storage in a storage site permitted under Directive 2009/31/EC;

   2. (ii)

      a transport network with the purpose of long-term geological storage in a storage site permitted under Directive 2009/31/EC;

   3. (iii)

      a storage site permitted under Directive 2009/31/EC for the purpose of long-term geological storage;

   b

   transferred out of the installation and used to produce precipitated calcium carbonate, in which the used CO₂ is chemically bound.

   2

   In its annual emissions report, the operator of the transferring installation shall provide the receiving installation's installation identification code recognised in accordance with the acts adopted pursuant to Article 19(3) of Directive 2003/87/EC, if the receiving installation is covered by that Directive. In all other cases, the operator of the transferring installation shall provide the name, address and contact information of a contact person for the receiving installation.

   The first subparagraph shall also apply to the receiving installation with respect to the transferring installation's installation identification code.

   3

   For the determination of the quantity of CO₂ transferred from one installation to another, the operator shall apply a measurement-based methodology, including in accordance with Articles 43, 44 and 45. The emission source shall correspond to the measurement point and the emissions shall be expressed as the quantity of CO₂ transferred.

   For the purpose of point (b) of paragraph 1, the operator shall apply a calculation-based methodology.

   4

   For determining the quantity of CO₂ transferred from one installation to another, the operator shall apply the highest tier as defined in section 1 of Annex VIII.

   However, the operator may apply the next lower tier provided that it establishes that applying the highest tier as defined in section 1 of Annex VIII is technically not feasible or incurs unreasonable costs.

   For determining the quantity of CO₂ chemically bound in precipitated calcium carbonate, the operator shall use data sources representing highest achievable accuracy.

   5

   The operators may determine quantities of CO₂ transferred out of the installation both at the transferring and at the receiving installation. In such cases, Article 48(3) shall apply.

4. (4)

   Article 52 is amended as follows:

   1. (a)

      paragraph 5 is deleted;

   2. (b)

      paragraph 6 is replaced by the following:

      6.

      Where the amount of fuel uplift or the amount of fuel remaining in the tanks is determined in units of volume, expressed in litres, the aircraft operator shall convert that amount from volume to mass by using density values. The aircraft operator shall use the fuel density (which may be an actual or a standard value of 0,8 kg per litre) that is used for operational and safety reasons.

      The procedure for informing the use of actual or standard density shall be described in the monitoring plan along with a reference to the relevant aircraft operator documentation.

   3. (c)

      paragraph 7 is replaced by the following:

      7.

      For the purposes of the calculation referred to in paragraph 1, the aircraft operator shall use the default emission factors set out in Table 2 in Annex III. For fuels not listed in that table, the aircraft operator shall determine the emission factor in accordance with Article 32. For such fuels, the net calorific value shall be determined and reported as a memo-item.

5. (5)

   In Article 54, paragraph 2, subparagraph 1 is replaced by the following:

   2.

   By way of derogation from Article 52, small emitters may estimate the fuel consumption using tools implemented by Eurocontrol or another relevant organisation, which can process all relevant air traffic information and avoid any underestimations of emissions.

6. (6)

   Article 55 is amended as follows:

   1. (a)

      paragraph 1 is replaced by the following:

      1.

   2. (b)

      paragraphs 2, 3 and 4 are deleted

7. (7)

   In Article 59, paragraph 1 is replaced by the following:

   For the purposes of point (a) of Article 58(3), the operator shall ensure that all relevant measuring equipment is calibrated, adjusted and checked at regular intervals including prior to use, and checked against measurement standards traceable to international measurement standards, where available, in accordance with the requirements of this Regulation and proportionate to the risks identified.

   Where components of the measuring systems cannot be calibrated, the operator shall identify those in the monitoring plan and propose alternative control activities.

   When the equipment is found not to comply with required performance, the operator shall promptly take necessary corrective action.

8. (8)

   In Article 65(2), a third subparagraph is added:

   Where the number of flights with data gaps referred to in the first two sub-paragraphs exceed 5 % of the annual flights that are reported, the operator shall inform the competent authority thereof without undue delay and shall take remedial action for improving the monitoring methodology.
