(Text with EEA relevance) (repealed)
THE EUROPEAN COMMISSION,
Having regard to the Treaty on the Functioning of the European Union,
Having regard to Regulation (EC) No 1107/2009 of the European Parliament and of the Council of 21 October 2009 concerning the placing of plant protection products on the market and repealing Council Directives 79/117/EEC and 91/414/EEC, and in particular the first sentence of Article 8(4) thereof,
After consulting the Standing Committee on the Food Chain and Animal Health,
Whereas:
(1)
In accordance with Regulation (EC) No 1107/2009, the dossier to be submitted for the approval of an active substance or for the authorisation of a plant protection product is to fulfil the same requirements in respect of the data requirements for the plant protection product as under the previously applicable rules which are set out in Annexes II and III to Council Directive 91/414/EEC of 15 July 1991 concerning the placing of plant protection products on the market.
(2)
It is therefore necessary for the implementation of Regulation (EC) No 1107/2009 to adopt a regulation containing those data requirements for active substances. Such a regulation is not to include any substantial modification,
HAS ADOPTED THIS REGULATION:
