data during the PLC-6 project mountainous areas of all these rivers and high retention in lakes between these regions and the sea. Sweden will evaluate this approach within the PLC-6 project, investigating the availability and continuity of point source and land use data and the expected nutrient retention in lakes and water courses. Based on these estimates, a decision will be taken as to whether to maintain the current approach (which assumes that the Norwegian contribution to the total from each of these three rivers is negligible compared to the Swedish ) or whether this approach should be re-evaluated and the rivers treated as conventional transboundary watercourses.

EU national point source code and E- PRTR sector type. PRTR sector codes and their descriptions can be found in table 15 or to be downloaded in http://prtr.ec.europa.eu/docs/Summary_activities.pdf. Reference sheet for each set of point source background information has been indicated in table 6 and the type and the format of each attribute has been listed in table 8. Once the definitions and background information of individual point sources have been updated in the database, a tentative list of information will be prefilled by the application when annual reporting templates are downloaded. In case the prefilled information doesn’t include all point sources to be reported, data manager should be contacted. Aggregated point sources cannot be prefilled and thus data manager should be contacted if point sources will be reported as aggregated. Table 6. Background information to be reported.
