art. 3.12: definition BAT-AELmeans the range of emission levels obtained under normal operating conditions using a best available technique or a combination of best available techniques, as described in BAT conclusions, expressed as an average over a given period of time, under specified reference conditions.
art. 15.3 a:ELVs shall be expressed for the same or shorter periods of time and the same reference conditions as those BAT-AEL

art. 15.4derogation of (a) and (b): in specific cases, on the basis of an assessment of the environmental and economic costs and benefits taking into account the technical characteristics of the installation concerned, its geographical location and the local environmental conditions, set emission limit values
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.
