The participants of the conference included the representatives of ministries and competent institutions for infrastructure, transport and environment protection as well as chiefs of regions adjacent to E40 from the three countries: Poland, Belarus and Ukraine. Currently, the waterway E 40 is used only at the section from Brest to Kherson but the waterway between Brest and Warsaw is unnavigable. So, it is necessary to restore this section. There are already three options of connecting Vistula with Brest in Belarus with the Mukhavets river. After conducting economic, hydro-technical, hydrological and social analyses, the team of experts, which have worked on the feasibility study of the international waterway E40, indicated the most important option of connection, i.e. the estuary of Wieprz to Vistula – Lower Vistula Valley – ice-marginal valley of Wieprz – Parczew Plain – Lomaska Depression – Koden Plain – The Bug river in vicinity of Terespol – estuary of the Mukhavets river. In total, it is 159.6 km. In order to open the Vistula and connect it with the Mukhavets River, it is necessary to conduct investments in form of dams on the Vistula and some minor actions in Belarus. The Ukrainian part is fully navigable. During the conference, the Commission presented its conclusions on the content of feasibility study on the development of waterway transport and cross-border economic development of the waterway with respect to spatial planning of the border areas, cross-border water resources and environmental issues. Moreover, the idea of restoration of the Dnieper- Vistula waterway on the European, national and regional level. The meeting ended with adapting the Resolution on support the actions aimed at restoration and development of the international waterway E40.
