22.12.2009 Official Journal of the European Union L 341/1 (Acts adopted under the EC Treaty/Euratom Treaty whose publication is not obligatory) DECISIONS COMMISSION COMMISSION DECISION of 30 November 2009 on the reference document referred to in Article 27(4) of Directive 2008/57/EC of the European Parliament and of the Council on the interoperability of the rail system within the Community (notified under document C(2009) 8680) (Text with EEA relevance) (2009/965/EC) THE COMMISSION OF THE EUROPEAN COMMUNITIES, Having regard to the Treaty establishing the European Community, Having regard to Directive 2008/57EC of the European Parlia- ment and of the Council of 17 June 2008 on the interoperability of the rail system within the Community (*), and in particular, Article 27(4) thereof, Having regard to the recommendation of the European Railway Agency (No ERA/REC/XA[01-2009) of 17 April 2009, Whereas: 1 Article 27(3) of Directive 2008/57[EC requires the Euro- pean Railway Agency to draft a reference document cross- referencing all the national rules applied by the Member States for placing vehicles in service. This document must contain the national rules of each Member State for each of the parameters listed in Annex VII to Directive 2008/57/EC and specify the group referred to in Section 2 of that Annex to which these rules belong. These rules must comprise those notified under Article 17(3) of Direc- tive 2008/57EC, including those notified following adop- tion of TSIs (specific cases, open points, derogations) and (1) OJL191,18.7.2008, p. 1. those notified under Article 8 of Directive 2004/49/EC of the European Parliament and of the Council (). The first version of the reference document is to be presented to the Commission no later than 1 January 2010. In order to allow comparison and cross-referencing, in respect of a particular parameter, between the require- ments contained within the TSIs and those contained in national rules, the list of parameters to be checked in con- junction with the placing in service of non-TSI conform vehicles, should, on the one hand, preserve compatibility with, and build upon existing agreements based on national rules and, on the other hand, reflect the TSIs. It is therefore necessary for the list of parameters to be at a level of detail significantly higher than that currently reflected in Section 1 of Annex VII to Directive 2008/57/EC. It is appropriate to adopt the detailed list of parameters set out in the Annex to this Decision as the basis for the reference document referred to in Article 27(4) of Directive 2008/57EC. The measures provided for in this Decision are in accor- dance with the opinion of the Committee established in accordance with Article 29(1) of Directive 2008/57EC, HAS ADOPTED THIS DECISION: (%) O] L 164, 30.4.2004, p. 44.
