law. As the ratification is done by sovereign states, the EU as a supranational body does not play a role. Consequently, International Conventions have priority over EU law. As will become evident, this may lead to friction between the rules at the international and supranational levels.

Figure 1 illustrates the situation and lists also a number of advisory bodies and/or guidance documents that are helpful, but are not legally binding.

EU law and dredged material EU law does not deal specifically with dredged material, nor is there any intent to do so. Nevertheless, a number of EU Directives have an impact on the management of dredged material, either directly or indirectly. Figure 2 presents an overview of the structure of the relevant Figure 1.

Figure 5. Where does the Water Framework Directive apply? In the northern Netherlands, a branch of the Rhine, the River IJssel, carried contaminated silt into Lake Ketelmeer where it settled into the bed. In an action to clean-up the waterway, the IJssel-oog (eye) repository was constructed for safe storage of contaminated dredged materials.

The reason is that coastal ports and harbours are very often located at, near or adjacent to Natura 2000 sites. This imposes on ports many restrictions in case they want to expand their site area or when they wish to build new infrastructure. In short port development projects face severe delays and increased costs, in particular when situated at the mouth of estuaries. Similar observations can be made for infrastructure development along valuable stretches of coastline.

The consequences for the dredging sector are likely to be indirect, but significant. The European dredging industry has noticed increasing problems with permits for infrastructure development in the marine environment and it faces increasing monitoring requirements in sensitive environments. A number of important infrastructure development projects have even been cancelled. Other impacts would entail such things as the presence of designated marine sites near ports, where disposal is not permitted; delays in infrastructure projects near designated sites and problems with establishing acceptable forecasts for habitat impact studies.

Again, there are also opportunities: The Habitats Directive foresees the possibility to provide compensation measures if valuable Figure 7.
