Tasks of Drafting Group III 1 Definition of point sources 2 How to derive restoration targets or quality standards? 3 What could be regulated in the Daughter Directive? 5 First estimation of costs and cost efficiency

Restoration target values? Landesumweltamt Point Source Emission limit values? Restoration target values? Environmental quality standards for surface waters? Quality standards? WRRL aus Richtlinienentwurf zur ökologischen Gewässerqualität hervorgegangen. Erster Entwurf im Jahr 1997 vorgelegt Beschluss im Rat am 14.09.2000, nur Dänemark enthielt sich der Stimme Obwohl gerade erst in Kraft getreten, befasst sich die LAWA schon seit einiger Zeit in zahlreichen Arbeitsgruppen intensiv mit der Thematik.

! Definition of point sources Point source: An identifiable and localised area, structure or facility which can cause pollution of groundwater (e. g. contaminated sites) ! New landfills and technical installations should only be considered as point sources if they actually cause groundwater pollution

Restoration target values A Europe-wide set of restoration target values for point sources (e. g. contaminated sites) is not appropriate: Different geological and hydrogeological conditions Individual pollution pattern for every point source Technical feasibility etc

Quality standards Pro quality standards Comparability between Member States (according to surface waters quality standards) Common standards for EU and common level of groundwater protection Contra quality standards Quality standards could become restoration target values Natural concentrations could exceed quality standards Importing standards from other directives does not fit for the purpose of groundwater protection

Tiered approach (subsidiarity) Regional-local level Measurements Tiered approach (subsidiarity) Regional-local level Assessment of points sources (vs groundwater) Inventorisation of potential point sources concept for prevention of contamination assessment strategy for point sources (focus groundwater and receptors

Measurements (2) Management concept for point sources historical-new contamination risk-based approach BAT don’t accept expanding plumes (within limited time frame)

Assessment of risks (vs GWB or sub-GWB) Measurements (3) EU-level + reporting Assessment of risks (vs GWB or sub-GWB) define “risk-zones” (vulnerability, land-use, …) implement monitoring (and reporting) system assessment strategy for risk zones (focus groundwater and receptors

Measurements (4) Management concept for risk zones historical-new contamination risk-based approach BAT don’t accept expanding plumes (within limited time frame)

Parameters? A EU-wide parameter list of substances for EU-relevant monitoring is desirable, EU-wide values are not required values will come out of site-specific risk assessment
