AGREGATION of Type B Strategic Noise Maps of a large infrastructure type railway axis.

European Directive 2002/49/EC of 25 June 2002 on evaluation and management environmental noise involves an assessment for EU Member States environmental noise in the vicinity of major transport infrastructure (land and air) and in large urban areas. This assessment is carried out in particular through the development of strategic ‘so-called’ noise maps. the first series of which were drawn up in 2007 (1st deadline of the Directive) and 2012 (2nd deadline). Article L572-5 of the Environmental Code states that these maps are "reviewed, and, where appropriate, revised, at least every five years.’ Thus, the implementation of this review leads, in 2017 and as appropriate, to revise or renew the previously developed maps. This document presents the main results of this 3 rd deadline. which concerns the national railway network of the department of Pyrénées-Orientales. Type B maps shall correspond to the areas affected by noise in accordance with the noise classification of land transport infrastructure established and agreed by the Prefect pursuant to Article L571-10 of the Environmental Code. This classification defines for future buildings of housing, education, health and hotels located in these areas affected by noise a minimum sound isolation of constructions. These requirements are laid down in the Decree of 30 May 1996, as amended by order of 23 July 2013. In the department of Pyrénées-Orientales, the sound classification of roadways or railway was the subject of an order dated 26 December 2012.
