(8)Directive 86/278/EEC requires Member States to provide a report on the implementation of that Directive on the basis of a questionnaire or outline drafted by the Commission in accordance with the procedure laid down in Directive 91/692/EEC. In order to avoid a legal vacuum due to the repeal of Directive 91/692/EEC, it is necessary to replace the reference to Directive 91/692/EEC with a reference to the procedure referred to in Directive 86/278/EEC.
