Article 1 
Member States in which ozone is used for treatment of drinking water shall vary or withdraw authorisations of plant protection products containing tolylfluanid by prohibiting any uses which may lead to contamination of groundwater or surface water by tolylfluanid or its metabolites, which results in contamination of drinking water by nitrosamines during the ozonisation process.
Article 2 
Member States shall, for the active substances for which they are rapporteur, investigate without delay whether the use of plant protection products containing such substances could lead to similar concerns. If the Member States referred to in Article 1 have indications that nitrosamines are formed and contaminate drinking water they shall take similar measures as those provided for in Article 1.
Article 3 
The Member States referred to in Article 1 shall ensure that the notifiers, at whose request tolylfluanid has been included in Annex I to Directive 91/414/EEC, submit to the rapporteur Member State within three months from the date of notification of this Decision studies on:

((a)) the leaching behaviour of this active substance; and
((b)) the conditions in which the formation of nitrosamines can be excluded.
Article 4 
Member States concerned by Articles 1 and 2 shall immediately inform the Commission on the measures taken. Within three months from the date of notification of this Decision, they shall also provide to the Commission an overview of actions they have taken as a result of this Decision.
Article 5 
This Decision is addressed to the Member States.
