- 175 - earthquake or flood of a "CSA level". Lastly, ASN will require EDF to strengthen its ties with the neighbouring operators, by means of conventions or detection and alert systems, to be rapidly informed of any event that could constitute an external hazard for its facilities, and to ensure coordinated emergency management with the neighbouring nuclear facilites and ICPEs operators. ASN also considers that EDF must examine the effects of the hazardous phenomena that could occur on industrial facilities containing hazards situated near its NPPs, taking into consideration the extreme situations studied in the CSAs. ASN will issue a requirement on this subject. Regarding the transport routes and pipelines situated in the site environment, EDF identifies them in the CSA reports and specifies the natures of the products carried in the pipelines. EDF concludes for all the sites that the transport of hazardous substances can present hazard risks, but that these risks are limited and that they meet the objectives of the fundamental safety rule (RFS) I.2.d relative to risks associated with the industrial environment and the transport routes. The CSA reports do not give an assessment of the consequences of these hazardous phenomena - potentially aggravated in the event of an earthquake or flood - on the facilities which could have been made more vulnerable by the said earthquake or flood. EDF indicates that such assessments have already been carried out during the periodic safety reviews of the various sites in application of RFS I.2.d and that they demonstrate compliance with the RFS criteria. EDF thus considers that in view of the existing assessments and the fact that these hazardous substances are not constantly present near the site, complementary studies of the hazardous phenomena associated with the transport routes beyond the baseline safety standards are not necessary. ASN nevertheless considers that EDF must assess the consequences of the hazardous phenomena associated with the transport routes and pipelines in the extreme situations studied in the CSAs, and draw its conclusions as to the complementary measures required. ASN shall issue a request in this respect. 6.1.4 Conclusion on the organisational provisions for accident management ASN considers that EDF's emergency organisation and resources must remain operational for hazard levels very much higher than those considered for the design of the facilities, and for radiological or toxic environmental conditions resulting from a severe accident affecting several facilities on a given site. Furthermore, ASN considers that these resources must be highly flexible so as to be capable of managing unforeseen situations. In addition, ASN considers that EDF's organisational and material emergency management provisions must be supplemented to manage a situation affecting several facilities on a given site, including in the event of extensive destruction of the neighbouring facilities. ASN also considers that EDF must analyse the applicability of the human actions required to manage the extreme situations studied in the CSAs, including the situations affecting all the facilities on the site and those that can affect the accessibility and habitability of the emergency management rooms. ASN will issue a requirement on this subject. 6.1.5 Measures envisaged to reinforce accident management capabilities In the CSA reports, EDF proposes several improvements or studies to reinforce the management of accident or severe accident situations on its sites. These improvements target more particularly: the appropriateness of the human and material resources for the activities associated with deployment of the "hard core" equipment and the additional equipment proposed further to the CSAs. This study will take the intervention conditions into account; the reinforcement of the material resources and communication means; the conducting of a study to improve the resistance and habitability of the BDS; the design of a Local Emergency Centre, integrating stringent habitability requirements and allowing more effective management of the emergency. The design requirements taken into account shall be consistent with those of the hard core; the reinforcement of the means of measurement and of technical and environmental information transmission, including meteorological information, necessary for emergency management;
