Priority Substances - Source Screening and Measures Sheets

1. Priority Substances - Source Screening and Measures Sheets Tenth Meeting of Working Group E on Chemical Aspects 24 June 2010

2. Structure of the presentation • Source screening sheets: methodology for revision and findings • Measures sheets: methodology and overview of new legislation

3. Source screening sheets – Methodology (I) • Methodology as specified in the 2005 Concept Paper • Up to date (since 2004) information sought from: • EU Sources • REACH (Annex XV Dossiers) • EU RARs • Plant Protection Products Directive • Biocides Directive • Prior Informed Consent • E-PRTR

4. Source screening sheets – Methodology (II) • International Sources • OSPAR Background Documents & Report on Emissions, Discharges and Losses • UNECE (Rotterdam Convention; CLRTAP; POPs) • FP6 Projects • Score-PP (substance flow analysis for selected priority pollutants in case cities) • SOCOPSE (source control of priority substances in Europe • Other information • Pesticides Manual • Trade Association Web-sites • Other reputable studies identified via Google searches

5. Main conclusions • Reductions can be seen in reported discharges from IPPC installations (data from E-PRTR) • However, industrial emissions are still significant for some substances • Use of some substances now banned (e.g. some pesticides) or restricted

6. Conclusions - pesticides • Pesticides not included in Annex I of Directive 91/414/EEC therefore use prohibited • Alachlor; Atrazine; Chlorfenvinphos; Endosulfan; Hexachlorocyclohexane (Lindane); Pentachlorophenol; Simazine; TBT; Trifluralin • Pesticides where use continues • Chlorpyrifos; Diuron; Isoproturon.

7. Conclusions – metals • Cadmium – industrial sources remain significant • Lead – industrial sources remain significant. Also discharges as a result of the use of lead products. Emissions to air from use of leaded petrol significantly reduced. • Mercury – use in chlor-alkali electrolysis industry significantly reduced but currently still important. Further reductions expected in coming years. • Nickel – emissions have reduced, but most sources still significant.

8. Conclusions – organohalogens(I) • BDEs – believed not to be produced in EU. Use restricted and significantly reduced. • C10-C13 chloroalkanes (SCCPs) – production and industrial use are significant sources. • 1,2-dichloroethane (EDC) – production and industrial use are significant sources. • Dichloromethane – domestic use prohibited, professional use restricted (to be prohibited in 2012), production and industrial use remain significant sources. • Hexachlorobenzene – no longer used or manufactured in the EU. No significant sources.

9. Conclusions – organohalogens(II) • Hexachlorobutadiene – no longer used or manufactured in the EU. No significant sources. • Pentachlorobenzene – no longer used or manufactured in the EU. Losses from historically contaminated sediments only significant source. • Trichlorobenzenes – one manufacturer in EU, used as a chemical intermediate. Production and industrial use are significant sources. • Trichloromethane (Chloroform) – use by public and in diffusive applications is prohibited. Industrial production and use are significant sources.

10. Conclusions – other organic substances (I) • Anthracene – industrial manufacture and use main significant sources. Creosote use restricted but leaching from historically treated wood and contaminated sediment significant sources. • Benzene – use in certain applications prohibited. Industrial production and use are significant sources. • DEHP – emissions as a result of product use are significant, together with industrial production and use. • Fluoranthene – little information available on production and use in EU. Most sources result in emissions of PAH/fluoranthene • Naphthalene – significant industrial emissions from combustion processes, basic organic chemicals and non-ferrous metal production. Atmospheric deposition not significant

11. Conclusions – other organic substances (II) • Nonylphenols – domestic use phased out. Reduction in industrial use but emissions still significant. • Octyphenols – significance of emissions as a result of tyre wear disputed. Emissions from non-IPPC installations likely to be more significant than those from IPPC installations. • PAH – significant reduction in emissions from IPPC installations observed, but most sources still significant.

12. Measure sheets – Methodology • Objective: To identify changes in measures since 2004 including new measures • Starting point: 2004 measures sheets • Up to date information sought from: • EUR-lex • Commission website / CIRCA / ENDS • International (OSPAR etc.) • Structured according to the 2004 measures sheets (source/pathways) • Reference to Directive 2008/105 on EQS in sheets under discussion

13. Issues identified in measures sheets - columns

14. Sources/pathways • Losses to surface waters by diffuse sources • Discharges to surface waters by point sources • Losses from historically contaminated sediments and soils • Emissions to atmosphere

15. Source/ PathwayS0 General Proposed: additional S0 row for relevant measures that does not directly relate to source/pathway:
