A Decision Support System for management of priority substances in river basin management plans Willy van Tongeren, Ruud Baartmans, Jaap van der Vlies, Anna Jöborn, Anna Palm-Cousins, Mohammed Belhaj, John Munthe, Tuomas Mattila, Susanne Ullrich, Jozef Pacyna, Kyrre Sundseth, Geraldine Ducos
Outline • Introduction: • Aim/background • Water Framework Directive/ RBMP’s • Decision Support System • Step by step plan • Tools • Web based application • Conclusions
WFD planning cycle Now, we are already here…
RBMP’s: Some key questions (for PS’s) • Actual and future status of waters? • Possible sources? • Possible measures? • Effects of measures: … concentration reduction?… costs? … other effects? • Who to consult, who to decide with? • Etc.
At some time, not far from now… Mr. Jones, Some-Where Water • Working at Some-Where Water • Is responsible for drafting a chapter on priority substances in the RBMP • Is neither a scientist nor an economist Fortunately, he has the SOCOPSEDSS Handbook which provides him guidance and an approach…
Aim • Support water authorities and other stakeholders to make plans and take decisions for the control of PSs • Identify current and future environmental problems • Asses effectiveness and impacts of various measures • Help to select the measures • At local, national and European level, and/or at river basin level (RBMP’s) • Transparent decision making • Make optimal use of local knowledge, experiences, etc.
Decision Support System Step by Step Plan Supporting Tools / Data bases, etc.
Approach • Based on socio economic evaluation methods • Structured, Step by step • Additional methods and tools • Strong Stakeholder involvement • Gives support, does not make decisions
Update plans (2015)
Step 0: System definition=(WFD requirement) • Define physical boundaries • Characterize geographical, physical, chemical, biological and societal conditions • Identify key stakeholders *tool in decision-making process
Step 1: Problem definition • To indicate: • Areas of EQS exceedance • Areas where PS concentrations increase in time • Result: table/map of indicating the areas where EQS’s are exceeded and/or where concentrations increase in time
Step 2: Inventory of sources Where is the pollution coming from and what is the level ? • EU wide inventory of major sources of emissions to air, water and soil which affect PS in various aquatic ecosystems (SFA, WP 2) • Which sources are relevant for areas of exceedance? • Calculate emissions from emission factors • Use of models
Step 3: Definition of baseline scenario(=Fine tuning the problem definition) • To what extend additional measures are necessary to improve water quality taking into account the measures already taken? • Is there a reason to assume that the present situation of water quality will change or will be different in future? • If so: why? • Will problem change?
Step 4: Inventory of possible measures Envisage relevant and possible management options for actual and future areas of exceeding (WP 4) • Measures for polluters • Process-oriented options • End-of-pipe techniques • Policy instruments • Substitution of product/substance • Community level options
Data base of abatement measures Census of all possible abatement and substitution measures by substance; It was constituted on the basis of: A bibliographic review : about 450 references ; A survey questionnaire : about 200 contacts ; Exchanges with stakeholders during 3 workshops: (Paris, Katowice, Nieuwegein.)
Database of “triplets”: measure-substance-emission source Excerpt from the database
Step 5: Assessment of the effects of the measures • What are the effects of measures? • Depict reduction of concentration • Costs of concentration reduction • Other relevant effects? Which?
Qualitative assessment: Type of pollution (Pol) Complexity of implementation (Cmp) Impact on the process of the factory (Imp) Limits and restrictions (Lim) • For each substance, we gathered and synthesized information (Substance = DEHP) Efficiency of emission reduction (Eff) Removal of other pollutants than SOCOPSE ones (Oth) Consumption of energy (En) Cross-effects (CE), Production of waste (W) Investment costs (IC) Operational costs (OC) Status of the technique (St) Number of applications (App) Excerpt from Substance Report on DEHP
Step 6: Selection of the best options • In dialogue with main stakeholder groups • Method:… Costs and concentration reduction: CEA… If also ‘other effects’: (quick scan) SCBA or MCA • No force to require means, only targets (EQSs):selection is advice to apply by the polluters
The MultiCriteria Analysis (ELECTRE Model INERIS): Ranking of triplets according to criteria and weights: Efficiency = 1/3 Share = 1/6 Costs = 1/6 Availability = 1/6 Co-benefits = 1/12 Scale = 1/12 Weights are allocated in order to get the same weighting between total costs and total benefits Total environmental benefits = 1/2 Total costs = 1/2
Quantitative assessment: For each substance, we asked experts to fill-in a data table: (Substance = DEHP) Excerpt from the datatable
Application at the European level for all substances: (Best measure by substance)
Tools • Models • Substance Flow Analyses • Substance reports • Fact Sheets • Additional tools • MCA, • SCBA, • Stakeholder analyses • ….
Conclusions • DSS can help different stakeholders with plan updates • Current RBMP • Future RBMP • Handbook and web based DSS user friendly: … Step by step plan … Measures for source-substance combinations… Environmental fate modelling… Economic evaluation methods • DSS developed & successfully tested in cases • Large differences in management structure • Large differences in data availability • Large difference in Data quality
Possible improvements / recommendations • How to deal with uncertainties • Data on sources • Effect of Measures: Costs !! • Matrix effects measures • Disturbance • Co-benefits • Other substances • Non-Technological measures • Links with other directives (REACH, ….) • Cooperation between countries (Emission Registration) • Update and maintenance !!??
Also this story has a happy end, So Mr Jones Changes to …
Thank you ScorePP Workshop:2-3 February 2010 willy.vantongeren@tno.nl www.socopse.eu
Water Framework Directive • A legal framework for achieving good ecological and chemical status in waters across Europe • Management by river basin • Limits in concentration of 33 priority substances(PSs) • Result obligation in 2015 (2027 ultimately) River basin management plans:First plan: 2009, updated plan: 2015
Step 4: Inventory of possible measures Input from Step 3 measures database future areas of exceedance and possible sources measure relevant for source? no skip measure yes table of possible (single) measures per source-substance combination does measureapply to more than 1 source or substance? yes consider to apply measure for more than 1 source or substance no table of possible measures per substance-source combination Input for Step 5
Step 5: Assessment of the effects of the measures Input from Step 4 information on use of fate models table of possible measures per source-substance combination calculate/estimate concentration reduction calculate/estimate Cost of Reduction Are there other effects besides Cost of Reduction and concentration reduction to be considered? yes depict these other effects no table of effects of measures, costs, reduction, other effects Input for Step 6

General aim: • Support the implementation of the WFD with regards to Priority Substances • Background: • SOCOPSE: focus on the development of tools to support the WFD implementation • 11 PSs: Hg, Cd, PBDE, TBT, Atrazine, Isoproturon, PAH, Anthracene, DEHP, HCB, NP • In this presentation: • Tools = 1) Inventory of abatement measures • 2) Assessment of abatement measures • 3) Emission Reduction Strategy with MCA
3) Emission Reduction Strategy The ERS regarding all SOCOPSE substances is built from the best measures by substance; The ranking of measures is processed with an outranking MultiCriteria Analysis model (ELECTRE); Database = Quantitative assessment table
