9.5.2007 Official Journal of the European Union L 119/49 COMMISSION DECISION of 4 May 2007 laying down protective measures concerning uses of plant protection products containing tolylfluanid leading to the contamination of drinking water (notified under document number C(2007) 1865) (Text with EEA relevance) (2007/322[EC) THE COMMISSION OF THE EUROPEAN COMMUNITIES, Having regard to the Treaty establishing the European Community, Having regard to Council Directive 91/414/EEC of 15 July 1991 concerning the placing of plant protection products on the market (1), and in particular Article 11(2) thereof, Whereas: (1) Tolylfluanid is an active substance included in Annex I to Directive ~ 91/414/EEC by Commission Directive 2006/6/EC (2. (20 On 23 February 2007 Germany informed the Commission that it has recently been discovered that tolylfluanid can have an unexpected effect on drinking water. Specifically, the use of a certain plant protection product, ‘Eurparen M WG’ which contains tolylfluanid, leads to the formation of a metabolite of tolylfluanid, namely dimethylsulfamide, which is likely to be found in the soil, and in groundwater and surface water. By a standard drinking water preparation process (ozon- isation) this metabolite is converted into a nitrosamine (NDMA) which is harmful to health. (3) Other active substances with a similar molecular structure as tolylfluanid could undergo the same degra- dation path. (4)  Nitrosamines are suspected or proven genotoxic and carcinogenic substances and their presence in drinking water should therefore be avoided. () O] L 230, 19.8.1991, p. 1. Directive as last amended by Commission Directive 2007/25/EC (O] L 106, 24.4.2007, p. 34). () OJ L 12, 18.1.2006, p. 21. ©) (6) Article 11(1) of Directive 91/414/EEC provides that if a Member State has valid reasons to consider that a product which it has authorised or is bound to authorise under Article 10 constitutes a risk to human or animal health or the environment, it may pro- visionally restrict or prohibit the use and/or sale of that product on its territory. It shall immediately inform the Commission and the other Member States of such action and give reasons for its decision. According to information received, the Czech Republic, Germany, Ireland, Spain, Italy, Luxembourg, Austria, Poland, Sweden and the United Kingdom, have already suspended the outdoor use of products containing tolyl- fluanid. Article 11(2) of Directive 91/414EEC provides that a decision is to be taken on the matter at Community level. In this case, urgent measures are needed to ensure that uses of plant protection products containing tolylfluanid do not lead to drinking water contamination. The problem is not limited to a single Member State, because contamination of groundwater or drinking water could have effects across national borders. As set out in its ninth recital, Directive 91/414/EEC aims for a high level of protection of health, groundwater and the environment. The fifth recital to Directive 91/414/EEC shows that it also aims at preventing unnecessary barriers to trade. Unilateral measures by Member States could lead to differing levels of protection, and also hinder trade in plant protection products. As a conse- quence, it is necessary to adopt measures at Community level. In the present case, warning through labelling is not sufficient to protect human health. Additional information should be collected to allow the Commission to review if necessary Directive 91/414/EEC as regards tolylfluanid. It should also be investigated whether the same problems could arise with other substances currently being assessed or already assessed at Community level. As a consequence, each Member State which has been appointed as a rapporteur for assessing an active substance under Directive 91/414/EEC should investigate without delay whether the use of plant protection products containing that substance could lead to similar concerns.
