Since March 5, 2026, it is possible to submit a modification file for an AIOT (Activities, Installations, Structures, Works that include ICPE and IOTA) via electronic transmission.
This new procedure called "MAIOT" allows:
-
better orientation of submitted files;
-
automatic receipt confirmation after file submission.
However, confidential documents should not be transmitted via this online service. They must be submitted directly to the instructing service in a separate paper envelope.
Additionally, it is not possible to modify an ongoing electronic procedure.
A Frequently Asked Questions document is available for any further information.
ICPE are installations that may pose dangers (explosions, fires...) or inconveniences (noise, odors...) to the environment.
Examples of ICPE include:
-
gas stations;
-
chemical plants;
-
automotive garages...
