# Commission Regulation (EU) No 546/2011 of 10 June 2011 implementing Regulation (EC) No 1107/2009 of the European Parliament and of the Council as regards uniform principles for evaluation and authorisation of plant protection products (Text with EEA relevance), Division 2.7.2

Extent: E+W+S+N.I.

Competent authorities shall evaluate the risk for the aquatic compartment where the possibility of the exposure of aquatic organisms has been established. A micro-organism may give rise to risks because of its potential through multiplication to establish itself in the environment and can therefore have a long-lasting or permanent impact on microbial communities or their predators.
This evaluation shall take into consideration the following information:
(a)the biological properties of the micro-organism;
(b)the survival of the micro-organism in the environment;
(c)its ecological niche;
(d)the natural background level of the micro-organism, where it is indigenous;
(e)information on fate and behaviour in the various parts of the environment;
(f)where relevant, information on potential interference with analytical systems used for the control of the quality of drinking water as provided for in the EU-derived domestic legislation which transposed Council Directive 98/83/EC;
(g)where relevant, other authorised uses of plant protection products in the area of envisaged use, e.g. containing the same active substance or which gives rise to the same residues.
