Annex 19

(Art. 6)

Pipeline installations

1 Principles

¹The risk report must contain all the information required by the enforcement authority in order to verify and assess, in accordance with Article 7, the risk posed by the pipeline installation to the public or the environment. This includes, in particular, all the information listed in numbers 2–5.

²In justified cases, certain items of information may be omitted or replaced by others which are equally valid or more appropriate.

³The scope and degree of detail of the information given for each item will depend on the specific circumstances; in particular, consideration is to be given to the specific type of pipeline installation, its hazard potential and the surrounding area, as well as to safety measures.

⁴Documentation used for the risk report, particularly test results, empirical data, literature references, results of calculations and detailed analyses, are to be kept at the disposal of the enforcement authority.

2 Basic data

21 Pipeline installation and surrounding area

– Description of the pipeline installation, together with a route/site plan, – information on the structure of the pipeline installation and technical and organisational data, – information on safety equipment, – information on the surrounding area, including a general plan.

22 Safety measures

– Technical standards, – measures taken to reduce the hazard potential, – measures taken to prevent major accidents, – measures taken to limit the effects of major accidents.

3 Analysis

31 Methods

– Description of the methods used.

32 Hazard potentials

– Overview and characterisation of the main hazard potentials.

33 Main major accident scenarios

– Possible causes of major accidents, – description of significant release events and their effects, based on dispersion considerations, – description of the extent of possible harm to the public or damage to the environment, – estimate of the likelihood of occurrence, given the safety measures in place.

4 Conclusions

– Account of the risk, given the safety measures in place, – estimate of the risk posed by the pipeline installation.

5 Summary of the risk report

– Characterisation of the pipeline installation and of the main hazard potentials, – description of the safety measures, – description of the main major accident scenarios, – estimate of the risk posed by the pipeline installation.
