(3)  Section 1.4.1 of Annex V to Directive 2000/60/EC Having regard to Directive 2000/60/EC of the European provides a process to ensure the comparability between Parliament and of the Council of 23 October 2000 establishing the biological monitoring results of Member States as a a framework for Community action in the field of water central part of the ecological status classification. This policy ('), and in particular Section 1.4.1(ix) of Annex V thereof, requires the Member States’ biological monitoring results and their monitoring system classifications to be compared through an intercalibration network comprised of monitoring sites in each Member State and in each Whereas: ecoregion of the Union.
