The definition of the programmes of measures requires economic analyses, notably cost-effectiveness analyses. The national timetable related to CEA is closely linked to the national deadlines related to the programme of measures building-up.

In 2005 Testing activities occurred in some districts in order to develop a methodology for CEA implementation at basin or sub-basin level. Exchanges took place within the national WFD group on economic issues and led to the drafting of a national document of guidelines on how carrying out the CEA (20 pages on 7 questions – 7 answers) District authorities were committed to draw up draft lists of the existing and planned basic measures, as well as of the possible supplementary measures for WB at risk of not meeting the good status. Lists should include information on the cost and effectiveness of the planned supplementary measures, in order to help their classification and the selection of the best combinations.

In 2006  The water authorities have to take into account the results of the French public consultation on the work programme and main water management issues (2 May to 2 November 2005) in the process of RBMP and PoM drafting. They are committed to hold local debates, go thoroughly into proposed measures, possibly proposed objective reports and dates of implementation. By mid 2006, first draft RBMP and PoM should be ready in each district, as water agencies need to adopt their financial support programme for 2007-2012 period, by the end of 2006. Draft should be divided into two periods : 2007-2009 and 2010-2015.

In 2007-2008 Water authorities will carry on local public debates and will refine the draft PoM and RBMP for 2010-2015.  From September 2007 to end March 2008, France will organise a public consultation on draft PoM and RBMP. By end 2008, water authorities will take into account the results of the consultation and refine the draft.  PoM and RBMP will be adopted in the beginning of 2009.

3. Identification of the risk of The identification of the measures is closely linked to the identification of the main water management issues (article 14 of the WFD). 6. Ensuring the overall relevance Analysing the impact of the common measures 1. Identification of the water bodies 2. Identification of the pressures Group 1 of measures : Struggle against eutrophication Issue 1 : eutrophication 3. Identification of the risk of not reaching the good status Group 2 of measures : Reduction of pesticide diffuse pollution Issue 2 : pesticides 4. Identification of the main water management issues 5. Identification of the new measures necessary to reach good status

General national methodology for CEA implementation When existing measures are enough to meet the objective of good status in time, the PoM draws up their list. The CEA of these measures is not required, as their implementation and timetable for implementation are set by regulatory texts coming from the transposition of European directives. When new supplementary measures are needed to reach the good status, the economic analysis makes it possible to identify the most efficient combination of measures. CEA allows to optimise a programme of actions and avoid waste of money to meet a determined objective.

General national methodology for CEA implementation First step : identifying a series of possible measures in order to address the local water management issues identified thanks to article 5 reports Undertaking this action requires local debates with involved partners. This step is not necessary when existing measures are enough to reach the objective.

General national methodology for CEA implementation Second step : building up several possible scenarios or strategies combining all or part of the measures identified during the first step. Information related to each measure is needed : cost level of contribution to the objective uncertainties other impacted fields Finally, the local debates should make it possible to highlight one strategy that appears as the most relevant and efficient one. If the gap between the estimated status in 2015 and the good status is reduced, it is likely that only one strategy will be possible.

General national methodology for CEA implementation Third step : defining the respective priorities between the different measures included in the selected scenario. The implementation of the most efficient measures needs to be optimised. The CEA allows to define the draft PoM that makes it possible to reach the WFD environmental objectives from 2015. Depending on the reactions of the local actors on this first draft PoM, a cost-advantage analysis can be undertaken.

 How to go from PoM scale to Water Body scale ? Measures are often identified at scale of a river basin or sub-basin where an issue needs to be addressed. Measures consequently deal with a group of WB. On a same geographical area, different issues can require several series of measures (for instance : eutrophication, biological continuity improvement, reduction of micropollutant withdrawal) In case of no other issues preventing from meeting the good status of the WB, the PoM will allow to reach the good status in all WB of the area. In cas of uncertainty on the evolution of a WB, measures could include a reinforcing monitoring of the status of this particular WB, in order to define possible complementary measures in view of the next PoM updating.
