The Prefect may, on his own initiative, on a proposal from the Director General of the Regional Health Agency, or at the request of the operator and in accordance with the procedure laid down inarticle R. 1322-6, issue an order amending the authorisation order, if he considers that the maintenance of certain provisions is no longer justified or that additional requirements are necessary in order to ensure the safety of the water distributed.
Before issuing the order, the Prefect may issue a reasoned decision requiring the operator to supply or update the information contained in the application file and to produce additional operating reports. The operator is responsible for these measures.
