2. 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.

3. 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.

4. 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 period, by the end of Draft should be divided into
two periods : and

 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.

7. 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.

8. 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.

9. 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.

10. 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.

12.  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.
