   THE COMMISSION OF THE EUROPEAN COMMUNITIES,
   Having regard to the Treaty establishing the European Community,
   Having regard to Directive 2000/60/EC of the European Parliament and of the Council of 23 October 2000 establishing a framework for Community action in the field of water policy (1), and in particular section 1.4.1(ix) of Annex V thereof,
   Whereas:
   
               (1)
            
            
               Article 4(1)(a)(ii) of Directive 2000/60/EC requires the Member States to protect, enhance and restore all bodies of surface water with the aim of achieving good surface water status at the latest 15 years after the date of entry into force of the Directive, subject to certain exceptions, in accordance with the provisions laid down in Annex V thereto. Article 4(1)(a)(iii) of Directive 2000/60/EC requires the Member States to protect and enhance all artificial and heavily modified bodies of water, with the aim of achieving good ecological potential and good surface water chemical status at the latest 15 years from the date of entry into force of that Directive, subject to certain exceptions, in accordance with the provisions laid down in Annex V thereto. In accordance with point (i) of section 1.4.1 of Annex V to Directive 2000/60/EC the references to ecological status should be construed as references to ecological potential as regards artificial and heavily modified water bodies.
            
         
               (2)
            
            
               Section 1.4.1 of Annex V to Directive 2000/60/EC provides a process to ensure the comparability between Member States of biological monitoring results, being a central part of the ecological status classification. This requires the results of the Member States' monitoring and classification systems to be compared through an intercalibration network comprised of monitoring sites in each Member State and in each ecoregion of the Community. Directive 2000/60/EC requires the Member States to collect, as appropriate, the necessary information for the sites included in the intercalibration network, in order to enable the assessment of the consistency of the national classification system with the normative definitions of section 1.2 of Annex V to Directive 2000/60/EC and the comparability of the results of classification systems between the Member States.
            
         
               (3)
            
            
               Commission Decision 2005/646/EC of 17 August 2005 on the establishment of a register of sites to form the intercalibration network in accordance with Directive 2000/60/EC of the European Parliament and of the Council (2) established the register of sites to form the intercalibration network referred to in section 1.4.1(vii) of Annex V to Directive 2000/60/EC.
            
         
               (4)
            
            
               In order to carry out the intercalibration exercise Member States are organised in Geographical Intercalibration Groups, consisting of Member States sharing particular surface water body types, as defined in Section 2 of the Annex to Decision 2005/646/EC. This has allowed each group to compare its results and to perform the intercalibration exercise among its members.
            
         
               (5)
            
            
               The intercalibration exercise is carried out at biological element level, comparing the classification results of the national monitoring systems for each biological element and for each common surface water body type among Member States in the same Geographical Intercalibration Group, and assessing the consistency of the results with the aforementioned normative definitions.
            
         
               (6)
            
            
               The ‘Technical report on the Water Framework Directive intercalibration exercise’ describes in detail how the intercalibration exercise has been carried out for the water categories and biological quality elements included in the Annex to this Decision.
            
         
               (7)
            
            
               The Commission has facilitated the intercalibration exercise through the Institute of Environment and Sustainability of the Joint Research Centre in Ispra (Italy) that has coordinated the technical work.
            
         
               (8)
            
            
               The intercalibration exercise is a complex scientific and technical task. The Geographical Intercalibration Groups have used different methodological options to carry out the exercise depending on the availability of monitoring data for the various biological quality elements and the status of development of the national monitoring and classification systems. In order to increase the statistical robustness of the results, most of the methodologies used by Geographical Intercalibration Groups involve the use of data from as many monitoring points as possible, covering the whole range of status classes, from high to bad status. Therefore, monitoring data has been used from sites that are not part of the intercalibration network, as this comprises only a limited number of sites of high, good or moderate status.
            
         
               (9)
            
            
               The Commission has received intercalibration results for a number of biological quality elements that comprise the definition of ecological status. In some cases results have been provided for only some parameters of the biological elements or for only some of the Member States participating in a Geographical Intercalibration Group. Hence, the Commission considers that, for those cases, comparability is not fully ensured. Further intercalibration results may therefore be subject to a future Decision when the relevant information in accordance with Section 1.4.1 of Annex V to Directive 2000/60/EC will have been provided by Member States.
            
         
               (10)
            
            
               It is necessary to adopt the available results of the intercalibration exercise on time to inform the development of the first river basin management plans and programmes of measures in accordance with Articles 11 and 13 of Directive 2000/60/EC.
            
         
               (11)
            
            
               As a result of the intercalibration exercise, the values of the ecological quality ratios for the boundaries between ecological status classes for the Member States classification systems should represent an equivalent ecological status. The differences in values for the same biological quality element are due to differences in national methods. In addition, due to the differences in calculation methods and other reasons, it is not possible to compare the values of the ecological quality ratios across different biological quality elements.
            
         
               (12)
            
            
               Parameters like chlorophyll-a concentration, phytoplankton biovolume, percentage of cyanobacteria or depth limits of macroalgae and angiosperms do not cover full biological quality elements. However, due to the availability of data and assessment methods, they are one of the basis of the current intercalibration exercise for lakes and coastal waters. The values of those parameters are directly comparable across Member States, provided the differences in sampling and analytical methods are taken into account. For these reasons, in addition to the ecological quality ratios, absolute values for these parameters should be included in the Annex to this Decision as part of the results of the intercalibration exercise.
            
         
               (13)
            
            
               The results should refer to the ecological status. If water bodies corresponding to the intercalibrated types are designated as heavily modified water bodies in accordance with Article 4(3) of Directive 2000/60/EC, the results presented in the Annex to this Decision may be used to derive their good ecological potential, taken into account their physical modifications and their associated water use, in accordance with the normative definitions in Annex V, section 1.2.5, to Directive 2000/60/EC.
            
         
               (14)
            
            
               As established in section 1.4.1(iii) of Annex V to Directive 2000/60/EC, Member States will have to translate the results of the intercalibration exercise into their national classification systems in order to set the boundaries between high and good status and between good and moderate status for all their national types. Guidelines to translate the intercalibration results into the national classification systems and to derive reference conditions have been developed to support the application of the results.
            
         
               (15)
            
            
               The information that will be made available through the implementation of the monitoring programmes provided for in Article eight of Directive 2000/60/EC and the review and update of the characteristics of river basin districts provided for in Article five of Directive 2000/60/EC can bring new evidence that may lead to the adaptation to scientific and technical progress of the Member States' monitoring and classification systems and eventually to a review of the results of the intercalibration exercise in order to improve their quality.
            
         
               (16)
            
            
               The measures provided for in this Decision are in accordance with the opinion of the Committee referred to in Article 21(1) of Directive 2000/60/EC,
            
         HAS ADOPTED THIS DECISION:
   Article 1
   For the purpose of section 1.4.1(iii) of Annex V to Directive 2000/60/EC, Member States shall use in their monitoring systems classification the values of the boundaries between classes that are set out in the Annex to this Decision.
   Article 2
   This Decision is addressed to the Member States.
