(C) Combined approach to discharges
Discharges into surface waters are controlled by a “combined approach for point and diffuse sources” (
Article 10(1)). The
Water Framework Directive as a matter of fact refers in this respect to other Directives, both those in force at the time of its adoption or subsequent ones, pertaining to water or impacted by water, included “any other relevant community legislation” (
Article 10(2)). The WFD thus provides that Member States shall ensure the establishment and/or implementation of a diversity of instruments. This includes, on the one hand, for point sources, emission limit values or controls based on available techniques. It refers, on the other hand, for diffuse impacts, to controls “including, as appropriate, best environmental practices” provided for by those other directives, a reference which thus appears to act as an implementation measure (
Article 10(2)).
