Important final outcome has been the development of the Program of Measures as part of integrated River Basin Management Plans. While to reach all the above actions, it was realized that an economic tools are important to identify the options and reach a certain predefined target. A report was developed to highlight the investments related to supplementary measures that are a priority to reduce ecological effects and the time period required for the objectives to be reached. Also the report describes the criteria for prioritization and analyzing the possibility of implementing the measures for the first time at a basin as well as national scale. A national overview related to the supplementary measures identified as a result of Cost Effectiveness Analysis, instruments and associated costs, necessary for reaching the environmental objectives was attained.
In this regard, 222 supplementary measures have been identified related to organic and hazardous pollution and nutrient pollution especially to the hydro morphological alterations and 261 related instruments. The total necessary costs are estimated around 584.224 million Euros. The financing of the supplementary measures is 41% from European funds, 23% from the state budget, 17% from local budgets and 18% from companies` financing sources. For the ecological effects, the highest ranking was associated with hydro morphological measures. Also other measures included structures such as fish ladders, artificial wetlands and river restoration however the probability to implement these measures in the first cycle of River Basin Management Plan (2012) is very low due to financial constraints. Only in few cases of hydro morphological related measures were registered with high certainty of implementation in 2012.
Most of the supplementary measures related to organic pollution especially those from point sources with generally a medium ecological effect were identified to be possible for implementation in 2012. This is due to the fact that these measures are a part of economic investment for actors in the planning process, for instance the extension and modernization of the sewage network. However, due to high financial investment costs related to basic measures, of the 19 billion Euros approximately 57% of the total supplementary measures are allocated to the first cycle of RBMP. Finally, in the framework of RBMP the Cost Effectiveness Analysis provides the basis for Cost Benefit Analysis. In fact for derogation of time for reaching the environmental objectives for these measures which are not eligible to be implemented in 2012 due to financial reasons.
