As the operator of an upper-class operating area, you are obliged to prepare a safety report containing at least the data and information listed in Annex II of the Hazardous Incident Regulation. The safety report shall be submitted to the competent authority within a reasonable time limit set by the competent authority before putting into service.

Safety reports shall be reviewed regularly, namely:

1. at least every five years,
2. in the event of an accident-relevant change in accordance with § 3 paragraph 5b of the Federal Immission Control Act,
3. after an event referred to in Part 1 of Annex VI, and
4. at any other time, if new circumstances so require, or to take into account the new level of safety knowledge and current knowledge for the assessment of the hazards.

If the review reveals that there could be a significant impact on the hazards associated with an incident, you must update the safety report immediately. The updated parts of the safety report shall be submitted to the competent authority without undue delay and, in the event of a change relevant to an incident, at least one month before the change is implemented.

The competent authority is obliged to inform you of the result of its examination of the safety report within a reasonable period of time, unless the safety report is the subject of an immission control approval procedure.
