Transcription

1 Water management, Water Framework Directive & Hydropower Common Implementation Strategy Workshop Brussels, September 2011 European State Questionnaire on Hydropower and the WFD 1. Context The 2 nd European CIS workshop on Water Management, WFD & Hydropower will be organised on September 2011 in Brussels by Germany, the UK and the European Commission. The 2011 workshop is practice and measures-oriented. It is based on the discussions initiated at the 1 st workshop on WFD & Hydropower (4-5 June 2007, Berlin) 1 and should be used as a forum to exchange information, experiences gained in the meantime and case studies on: 1. Options and tools of European States in order to implement measures for the improvement and achievement of GES or GEP: a. Legal tools and legal requirements b. Technical standards and requirements c. Incentives 2. Strategic planning tools on the catchment scale for the designation of appropriate, less appropriate and not appropriate areas for new hydropower plants. 3. Approaches for the implementation of WFD Article 4.7. An issue paper will be prepared for the workshop. In order to collect background information for the workshop issue paper, European States are kindly asked to fill in the present questionnaire on Hydropower and the WFD. Please fill in one questionnaire per European State and return to eleftheria.kampa@ecologic.eu and stephan.naumann@uba.de at the latest by 17 June General information Name of European State Slovakia Name and contact details of person to be contacted if any clarifications on the reply to this questionnaire are needed: Kelnarová Zdena 1 See Key Conclusions, Common Implementation Strategy Workshop on WFD & Hydropower, Berlin, 4-5 June Available online: 1
