art. 15.4:ELVs shall ≤ emission limit values set out in Annexes V to VIII of the Directive

the ELVs of Annexes V –VIII are independent of the sector an can be seen as the absolute limit for emissions

Methodology for determining BAT-AELs» Stepwise methodology based on detailed analysis of existing

emission data and background information» BATs are known

Step 1• Selection of industrial installations

Step 2• Collection of emission data

Step 3• Selection of parameters

Step 4• Analysis of emission data in relation to BAT

Step 5• Determination of (differentiated) BAT-AELs

Conclusions

» Up to now: no clearly established and generally accepted methodology for determining BAT-AELs at sector level

» Methodology developed:» Will increase objectivity and transparency of BAT-AELs

determination process» Will increase level of consensus on BAT-AELs, thus ELVs» Is also applicable for determining BAT-AELs for other

environmental aspects (other than discharge of industrial waste water)

» It is essential that industry is involved in process of determining BAT-AELs and is prepared to provide necessary information !BREF with well founded BAT-AELs will lead to similar

permit conditionsand a better environment.
