02 03 04 05 06 07 08 09 10 11 12 13 14 AP With regard to the management of sites contaminated by radioactivity subject to the ICPE System and the Public Health Code, whether the party responsible is solvent or insolvent, in accordance with its validated doctrine regarding sites contaminated by radioactive substances (see chapter 14, point 1.2.2), ASN recalls that the clean-out practices must be implemented taking account of the best available methods and techniques, in economically acceptable conditions. The complete POCO scenario must always be envisaged as the reference scenario. This scenario, which leads to unconditional release of the buildings and sites, effectively enables the protection of people and the environment to be guaranteed over time by the removal of all contamination. In the event of identified technical, economic or financial difficulties, the party responsible for the contamination (if solvent) or the owner of the site may propose one or more appropriate POCO scenarios compatible with the site’s futures usages (confirmed, planned and possible) to the Prefect. Whatever the case, elements proving that the reference scenario cannot be applied under acceptable technical and economic conditions and that the POCO operations envisaged constitute a technical and economic optimum shall be provided. In the event of incompatibility with the usages as a whole, usage restrictions or prohibitions and technical measures to limit exposure of the occupants, or prescribe surveillance measures may be adopted, through active institutional controls or a soil hazard information sector. Whatever the case, the Prefect may rely on the opinion of the classified installations inspectorate, ASN and the Regional Health Agency (ARS) to validate the site rehabilitation project, and issues a prefectural order to govern implementation of the rehabilitation measures. ASN may thus be called upon by the services of the Prefect and the classified installation inspectors to give its opinion on the clean-out objectives of a site.
