3. Intercalibration register

4. IC register – state of play
Deadline for site submission 21 September 2004
 Final draft of the intercalibration register
Presented and discussed in WFD Committee (29 October)
 Minor adjustments requested by Member States
Final site lists included in Commission Decision on the Intercalibration Register (Annex A1)
 Committee voting spring 2005

5. Intercalibration register: 1500 sites
Rivers
Lakes
Coastal
Transitional

6. 883 Rivers Northern GIG Central/Baltic GIG Alpine GIG
Eastern Continental GIG
Mediterranean GIG

7. 327 Lakes Northern GIG Central/Baltic GIG Atlantic GIG Alpine GIG
Mediterranean GIG

8. 190 Coastal, 42 Transitional NE Atlantic GIG Black Sea GIG Baltic GIG
Mediterranean GIG

9. Numbers of sites by country
Sufficient sites submitted
No sites as agreed
No sites, no agreement

10. Intercalibration site submission scoreboard…
24 Member States,
Norway, Romania, Bulgaria 
Malta – will provide sites ASAP

11. Intercalibration sites and class boundaries…
Intercalibration sites represent Member State’s view on high-good and good-moderate class boundaries
Harmonised boundaries should be the outcome of the IC exercise
There may be a need to revise register to represent harmonised boundaries

14. KEY PRINCIPLES OF THE INTERCALIBRATION PROCESS (1)
Setting of good status class boundaries:
Consistent with WFD definitions
Comparable between all 25 Member States
high
good
moderate
poor
bad 1 OK
Restoration
needed
EQR

15. KEY PRINCIPLES OF THE INTERCALIBRATION PROCESS (2)
Intercalibration requires that all Member States will have developed national WFD assessment methods in time (2005-6)
IC undertaken within Geographical Intercalibration Groups of countries (GIGs)
IC limited to selected common types, pressures and quality elements

16. PROCESS OPTIONS FOR INTERCALIBRATION
IC guidance identifies three alternative options for intercalibration, depending on:
State of development of classification methods
Diversity of approaches between countries
Data availability
All options include:
application of an agreed procedure for establishing reference conditions and setting class boundaries (Annex I)
Identification of intercalibration sites representing the class boundaries

17. ANNEX I. BOUNDARY SETTING PROCEDURE
Establish data set
illustrating RC and
degradation across a
pressure gradient
Agree on
reference conditions
Criteria for HG and GM
class boundaries
Good status class boundary
values consistent with
WFD definitions
Apply criteria to data set
and establish boundary
EQRvalues
Explicit descriptions of how class boundaries are set

21. Concluding remarks
Intercalibration network established according to WFD timetable
possible need for revision to take into account the outcome of the IC exercise
Intercalibration process has started in groups of MS based on IC process guidance
Intercalibration is resource-intensive
Resources need to be provided by Member States
