Guide méthodologique pour l'élaboration des dossiers de demande d'autorisation d'Installations Classées pour la Protection de l'Environnement (ICPE) en matière de pisciculture marine pour la région Corse

Sea fish farms with production of more than 20 tons per year in France must obtain two operating licences: (i) one for Sea Farming (AECM), with the aim of ensuring that the granted site and use of the maritime public domain for exploitation will respect all restrictions of general interest; (ii) one for regulating Facilities Classified for the Protection of the Environment (ICPE). Although the first one requires a relatively simple licence request file, the second one demands a very complete file, which includes, beyond the notice of exploitation information, a complete impact study, as well as a hazards study and a health and safety notice. In this context, petitioners in Corsica (adjustment of status or new exploitation) are faced with the same difficulties, which highlighted the need for a methodological guide adapted to each region's specific situation, assembling in particular the necessary baseline data (legal, zootechnical, geographical, climatic, socio-economic, ecological...) as well as recognised methods for evaluating the potential effects of the farm on the environment. Development of this guide was supported by ADEC and supervised by a steering committee composed of representatives from the administrations concerned, fish farmers and scientific bodies. The significant aspects dealt with the effects of fish farming on Posidonie herbarium, a protected species very present in Corsica and with coordinating the two AECM and ICPE procedures. For each part of the ICPE file, the guide introduces the technical or scientific context and, depending upon the case, the state of the art, sources of available data, acquisition and methods of acquiring measurements and of assessing the potential effects, as well as practical editing recommendations. Finally, the guide is made complete by a model schedule of conditions designed to help petitioners to have a specialist research department incorporate all or part of the file. This guide primarily concerns first-time marine facilities for exploitation in Corsica, conceived of as in the open sea rather than in confined spaces. Nonetheless, any fish farmer or future fish farmer needing to process a request for an exploitation licence may find it useful.
