Change in operation


  • L512.15 of the environmental code
  • Articles R512-33 and R512-34 of the environmental code

The Prefect must be informed, prior to its implementation, of any modification made by the applicant to the installation, operating method or environment, likely to result in a significant change in the elements of the permit application, with all background information. If necessary, the Prefect imposes additional operational requirements after consulting with CODERST.
If he deems, upon advice from the Inspectorate of classified installations, that the modifications are likely to result in new hazards or nuisances, the Prefect asks the operator to submit a new permit application.
