  7. 7. Niina Vieno 7 EU LEGISLATION • EU Member States are free to adopt legislation in the absence of EU legislation • Where the Community has acted, EU legislation is supreme and binding, taking precedence over both past and future Member State actions • Member States must at least, fullfil the requirements of the EU directives Finland Sweden Germany
  8. 8. EU legislative framework Niina Vieno 8 Directive on industrial emissions (2010/75/EU) European Pollutant Release and Transfer Register (166/2006) CLP-regulation (1272/2008) INDUSTRY MUNICIPAL WASTE WATER TREATMENT PLANT AQUATIC ENVIRONMENT SEWAGE SLUDGE Urban wastewater directive (91/271/EEC and 98/15/EC) Water Framework Directive (2000/60/EC) Priority substances Directive (2013/39/EU) Sewage Sludge Directive (86/278/EEC) Applies for specific industries e.g. Animal by-products directive (1069/2009)
  9. 9. Directive on Industrial Emissions (2010/75/EU)  In order to prevent, reduce and as far as possible eliminate pollution arising from industrial activities in compliance with the ‘polluter pays’ principle and the principle of pollution prevention Environmental permit Niina Vieno 9  The permit should also include emission limit values for polluting substances  Directive does not prevent Member States from maintaining or introducing more stringent protective measures.

  11. 11. Production and processing of metals  Metal ore (including sulphide ore) roasting or sintering  Production of pig iron or steel (primary or secondary fusion) including continuous casting, with a capacity exceeding 2,5 tonnes per hour  Processing of ferrous metals:  operation of hot-rolling mills with a capacity exceeding 20 tonnes of crude steel per hour;  operation of smitheries with hammers the energy of which exceeds 50 kilojoule per hammer, where the calorific power used exceeds 20 MW;  application of protective fused metal coats with an input exceeding 2 tonnes of crude steel per hour.  Operation of ferrous metal foundries with a production capacity exceeding 20 tonnes per day  Processing of non-ferrous metals:  production of non-ferrous crude metals from ore, concentrates or secondary raw materials by metallurgical, chemical or electrolytic processes;  melting, including the alloyage, of non-ferrous metals, including recovered products and operation of non- ferrous metal foundries, with a melting capacity exceeding 4 tonnes per day for lead and cadmium or 20 tonnes per day for all other metals.  Surface treatment of metals or plastic materials using an electrolytic or chemical process where the volume of the treatment vats exceeds 30 m3 Niina Vieno 11
  12. 12. European Pollutant Release and Transfer Register (E-PRTR) (166/2006)  Releases of listed pollutants that must be reported by the operators of the facilities carrying out the specific activities, such as:  Production and processing of metals  Urban wastewater treatment plants of > 100.000 p.e.  No limit values has been decreed  Annex II lists pollutants and threshold values for reporting Niina Vieno 12
  13. 13. CLP-regulation (1272/2008)  Classification, Labelling and Packaging of chemicals substances and mixtures.  Especially substances classified as hazardous to the aquatic environment should be considered when dealing with industrial wastewaters Niina Vieno 13
  14. 14. Urban wastewater directive (91/271/EEC and 98/15/EC)  The Directive require Member States to establish systems of prior regulation or authorisation for discharges of industrial wastewater into urban sewage collecting systems to ensure:  Treatment plant operation and sludge treatment will not be impeded;  No adverse effect on the environment (including receiving waters) will occur; and  The safe disposal of sewage sludge.  Annex I lists general requirements for industrial wastewater discharged into urban collecting systems. Niina Vieno 14
  15. 15. General requirements  Industrial waste water entering collecting systems and urban waste water treatment plants shall be subject to such pre- treatment as is required in order to :  protect the health of staff working in collecting systems and treatment plants,  ensure that collecting systems, waste water treatment plants and associated equipment are not damaged,  ensure that the operation of the waste water treatment plant and the treatment of sludge are not impeded,  ensure that discharges from the treatment plants do not adversely affect the environment, or prevent receiving water from complying with other Community Directives,  ensure that sludge can be disposed of safety in an environmentally acceptable manner Niina Vieno 15
  16. 16. Priority substances in the field of water policy (2013/39/EC)  As a matter of priority, causes of pollution should be identified and emissions of pollutants should be dealt with at source, in the most economically and environmentally effective manner.  List of  Hazardous substances (emissions should be reduced)  Priority hazardous substances (cessation or phasing out of discharges and emissions) Niina Vieno 16

  21. 21. Industrial wastewater agreements  Finnish Water Utilities Association:  Industrial wastewater guide – conveying direct non- household wastewater to sewers Niina Vieno 21 INDUSTRY MUNICIPAL WASTE WATER TREATMENT PLANT AGREEMENT Municipality Regional State Administrative Agencies Centre for Economic Development, Transport and the Environment
  22. 22. Content of the agreement  Contains terms in regard to:  Wastewater quantity and quality (e.g. pH, BOD, nutrients, hazardous substances)  NOTE that the wastewater treatment plant can decide on the limit values for hazardous substances  How the wastewater is discharged to the public sewer  Pre-treatment of the industrial wastewater  Obligations regarding communication  Monitoring of the wastewater quantity and quality  Tariffs  Contractual terms (changes, terminations, liability of damages, sanctions) Niina Vieno 22
  23. 23. Wastewater tariffs  For industrial wastewaters, tariffs are normally defined by multiplying the residential tariff by factor that is > 1.  This factor takes into account additional costs caused to the municipal wastewater treatment plant due to  maintenance of sewers and the treatment plant, and  hindrances in the treatment process caused by the different quality of the industrial wastewater compared to the municipal wastewater  The quantity and quality of the industrial wastewater affects on the tariff  Tariff is different for every facility Niina Vieno 23
  24. 24. SWEDEN Niina Vieno 24  Swedish Water and Wastewater Association has published a guide for municipal wastewater treatment plants on receiving industrial wastewater.  Focus is on environmentally hazardous substances  The industrial facility is responsible in finding out and reporting the substances and their concentrations in the wastewater intended to be discharged to the public sewer.  Wastewater treatment plant can decide on the limit values for hazardous substances:  Substances can be hazardous to the sewers (e.g. corrosion)  Substances can affect the wastewater treatment, the quality of sludge or the quality of the receiving surface water.
  25. 25. For example: Käppala WWTP  Guides for pre-treatment of industrial wastewaters  E.g. WWTP recommends that the wastewaters from washing hands in metal industry should be pre- treated due to increased concentrations of cadmium in wastewater. Niina Vieno 25
  26. 26. GERMANY  German Wastewater Regulation defines State of the Technical Art with respect municipal wastewater as well as regarding wastewater from several industries  Minimum requirements are valid for the whole Federal Republic of Germany.  Every state can decide on the specific requirements  Specific demands on wastewater of given industry segments before this sewage is mixed with other wastewater  Demands relate to harmful substances Niina Vieno 26
