Order dated 24 January 2011 published in the Official Journal of 31 March 2011 sets out seismic rules applicable to classified installations subject to authorization.
These classified installations are subject to the regulations for buildings, equipment and facilities included in the seismic category known as "normal risk" (please refer to the Legal and regulatory update - November 2010).
Some equipment within these classified installations is the subject of a study to determine the technical implementations necessary for their protection against earthquakes.
With regard to existing classified installations, this study must be filed no later than 31 December 2015 and before 31 December 2016 the prefect will have to put in place the timetable for implementing protection against earthquakes for this equipment. This should be carried out by 1 January 2021.
New classified installations, authorized after 1 January 2013, must comply with the new requirements.
