Any new application for approval is made under the same conditions and according to the same procedure as that used to grant the initial approval:
– in the case of a permanent modification to the enclosure or its layout, the documents listed in article A. 312-3 are produced for the modified part of the structure;
– in the case of a modification to the environment, the documents listed in article A. 312-4 are produced, updated if necessary, as well as a document specifying the nature of the modification (exhibit 18).
In both cases, the new application must be accompanied by a copy of an approval register, the content of which is set out in appendix III-3 to this code.
