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 inputs from each of these three rivers is negligible compared (BOS): Transboundary NO/SE SE Total area: 26,726 km2 NO: 7.9 % SE: 92.1 % SE: SE: Sweden to investigate the availability and continuity of point source and land use data during the PLC-6 project (BOS): Transboundary NO/SE SE Total area: 31,864 k m2 NO: 4.9 % SE: 95.1 % SE: SE: Sweden to investigate the availability and continuity of point source and land use data during the PLC-6 project

(*** Only for individually reported point sources ADDITIONAL INFORMATION ON POINT SOURCES In addition to the discharges of MWWTPs, information on LOQ or LOD, number of measurements (NR_MEASUREMENTS), treatment method (TREATMENT_METHOD), number of population equivalent (NR_PE) should be reported for each individual MWWTP, as well as the information on sampling methodology (e.g., non-systematic, systematic, etc.), uncertainty (in %) and used methods of calculation and/or estimation (METHOD_ID) of loads. Additional data on individually reported industrial plants include information on Limit of quantification or detection (LOQ or LOD), number of measurements (NR_MEASUREMENTS), treatment methods, (TREATMENT_METHOD), PRTR sectors, sampling methodology, total uncertainty (in %) and used methods of calculation and estimation of loads (METHOD_ID). Wastewater treatment methods are listed in tables 10a and 10b and calculation and estimation methods in table 11 for individual MWWTPs and INDUSTRIAL PLANTs. PRTR sectors for industrial plants have been listed in table 12. Apart from reporting the loads of aquacultural plants, amount of feed (as t/a), feed type (moist, semi-moist and dry) and production (in t/a) can be reported on a voluntary basis in the AQUACULTURE_PRODUCTION sheet. Total uncertainty (TOT_UNCERTAINTY, in %) of the obtained loads and used methods (METHOD_ID) can also be reported. The methods are listed in table 13. Table 9.
