Article 6
1. A Member State wishing to approve project activities as a host country after the deadline for the submission of the national allocation plan shall inform the Commission thereof, prior to the issuance of the letter of approval. This information shall be accompanied by a report of an independent verifier which verifies that any ERUs or CERs to be issued do not result in double counting, in doing so providing all necessary information ensuring that the project activities submitted for approval are in compliance with Article 11b of Directive 2003/87/EC. 2. Letters of approval issued in accordance with Article 3(2) and letters of endorsement issued after the deadline for the notification of the national allocation plan set out in Article 9(1) of Directive 2003/87/EC for project activities that will result in trading sector project-reductions shall assign the allowances that are to be converted into assigned amount units from the set-aside established pursuant to Article 3(2) in the event of the issuance of ERUs or CERs. If an allowance was already assigned by a letter of approval to a particular project activity for future conversion, it cannot be reassigned to another project afterwards.
