Overview Additional ongoing exemplification work under Cefic coordination:  Overview Additional ongoing exemplification work under Cefic coordination Arona meeting 7 and 8 Nov 2006 L. Heezen Cefic Slide2:  CEPE: steel structure coating CEPI/EPCG: paper chemicals Dystar: textile and leather dyes Eurométaux: metals industry ATIEL: lubricants (Meth)acrylate EFMA: fertilizers Slide3:  CEPI/EGCG Paper chemicals Slide4:  Exposure Scenario’s (ES) for pulp & paper making and paper converting (1/2) The European Paper Chemicals Group (EPCG) and CEPI (Confederation of European Paper Industries) and their members Basis is the Council common position (June 2006) Includes all steps from substance production to final end use of the product Study is conducted with classified and non classified substances Toxicity and hazard data by EPCG; Use and Exposure information by CEPI A downstream user checklist for the exposure scenario model (VCI methodology) was developed ENV/251/06 Slide5:  Exposure Scenario’s (ES) for pulp & paper making and paper converting (2/2) Use and exposure category / exposure scenario - precise description of the general terms and refinement of certain aspects of scoping study (e.g. timing / frequency of exposure) - evaluation of the applicability for the paper sector CSR and enhanced SDS - to be developed for 2 substances of the study Main issues facing - the given exposure & use categories: potential differences in human and environmental assessment by suppliers and mills - how far to go into the waste issue? Slide6:  Dystar Textile and leather dyes Exposure Scenario´s (ES) for production of a dye and its use in dyeing processes :  Exposure Scenario´s (ES) for production of a dye and its use in dyeing processes Manufacturer of the substance and formulator of the dye preparation (DyStar), final industrial user, VCI and TEGEWA (german industrial associations) Basis is the Council common position (June 2006) Includes production of a substance,formulation of a preparation, use in a pilot plant and final use of the substance by an industrial company (e.g. dyeing house) Study is conducted with a classified substance Toxicity and hazard data by DyStar, use and exposure information by DyStar (pilot plant) and an industrial company (dyeing house) Exposure scenario model (VCI methodology) is used Exposure Scenario´s (ES) for production of a dye and its use in dyeing processes:  Exposure Scenario´s (ES) for production of a dye and its use in dyeing processes Use and exposure category /exposure scenario Precise description of the general terms and refinement of certain aspects (e.g. duration, frequency of exposure) Evaluation of the applicability for e.g. a textile dye CSR and extended SDS To be developed for one substance and a corresponding preparation as a representation for a dye Main issues facing Exposure and use categories: potential differences in human and environmental assessment by manufacturing, formulating, dyeing in a pilot plant and dyeing in an industrial company How far to go into details Slide9:  Eurométaux Metals industry Slide10:  Developing ES for the metals Aim: Develop generic guidance for drafting integrated ES for the metals industry Working Group: Eurometaux platform (including commodities and downstream users) Done so far: From the EU-RAs Cd, Ni, Zn, Pb, Cu metal: Identification of life cycle steps Identification of activities, potential for exposure, type of exposure Identification of the exposure reduction measures Elaboration of exposure scenario examples Ongoing: Development of generic exposure scenarios To be done: development of exposure library, terminology Slide11:  Hazard Exposure route RMM Supply Chain Step Process Step Substances of Concern metal PRODUCTION DU - PRODUCTION OF metal ARTICLES and metal-ALLOY ARTICLES 1) Raw material handling: metal concentrate delivery, blending and drying 2) Thermal processes: Smelting, converting, casting 3) Electrolysis massive metal metal-dust metal-fumes metal-fumes Systemic Systemic Systemic Inhalations Air emissions Water emissions Crane with filtered air cabin Full face mask – type P2 –Air filter -WWTP ES N* 1 2 3 2) Thermal processes: melting and sand casting or die casting 3) Mechanical processes: drawing, rolling, grinding metal-dust metal articles 4) Cleaning & maintenance 4) Cleaning & maintenance Systemic Inhalations Air emissions Water emissions Inhalations Air emissions Water emissions Inhalations Air emissions Water emissions 2 1) Raw material handling 1 metal-dust Systemic Inhalations Air emissions Water emissions Full face mask – type P2 –Air filter -WWTP Full face mask – type P2 –Air filter -WWTP Full face mask – type P2 –Air filter -WWTP Crane with filtered air cabin Full face mask – type P2 –Air filter -WWTP 4 4 Example: activity: raw material handling :  Example: activity: raw material handling Description: This operation is performed with a conveyer belt and a crane. It involves manual sorting and handling of raw material. Duration and frequency: 4 hours/day, 200 days/year Worker protection: Automated – closed process: crane with a cabin with filtered air (95% efficient). Manual handling: LEV (80% efficient), gloves, protective clothing and RPE (full face mask type P2) are required. Air emissions: Air filter with an efficiency of at least 90% Waste water: Cleaning water discharged to a WWTP; physico- chemical treatment Hazardous waste: Used air filters and spills Volume waste: Empty containers and air-dry clothing Slide13:  ATIEL Lubricants R.I.P. 3.2-2 Lubricants Pilot Study:  R.I.P. 3.2-2 Lubricants Pilot Study Addition to pilot study program October 2006 Lubricants pilot study will be carried out by ATIEL and ATC members Development of exposure scenarios for blending, application and possibly manufacturing Concentrating on impact of base oil and additives Late entry into program will limit output to one set of scenarios by target of January 2007 First phase Identify lubricant for investigation Second phase Identify typical application (use) Third phase Complete exposure scenario according to guidance document Slide15:  (Meth)-acrylates Exposure Scenario´s (ES) for (Meth)acrylate industry:  Exposure Scenario´s (ES) for (Meth)acrylate industry Case study represents a typical Commodity Chemical with complex route to a dispersive market Matrix of uses has identified over 100 scenarios including Production of Monomer, Production of Preparations, Polymers (several processes) and Articles by Industry and Use by Industry, Professionals and Consumers Some DU sectors represented by Associations others with no exsiting mechanism of effective communication Study would be conducted with substance classified for supply, polymers and articles Exposure Scenario´s (ES) for (Meth)acrylate industry:  Exposure Scenario´s (ES) for (Meth)acrylate industry Use and exposure category /exposure scenario Include basis for grouping of like scenarios based upon exposure (HH & E) potential to identify generic scenarios Select two generic scenarios represented by Uses for which precise description of activities will be established with use association (e.g. Task duration, frequency of exposure etc.) Evaluation of the applicability of approach for Commodity Chemical with dispersive uses CSR and extended SDS To be developed for one substance (monomer), a corresponding preparation and a polymer representative of the (meth)acrylate industry Development of standardised descriptors, RRMs etc. Main issues preventing commitment Complexity of downstream market typical of a Commodity Chemical Insufficient time to complete with available resources Examples of DU could only address those with established communication routes i.e. Trade association within timeframe How far to go into details without over simplifying complexity EFMA Fertilizer – case:  EFMA Fertilizer – case Fertilizer grades vary from straight substances to very complex preparations:  Fertilizer grades vary from straight substances to very complex preparations Straight fertilizers (one chemical substance), e.g.. Urea Ammonium nitrate Complex fertilizers, e.g.. NPK's, containing Minerals and chemical substances containing N, P and K Their double salts Solid solutions Fillers (e.g.. limestone, dolomite) Micronutrients = e.g.. salts of Copper, Boron, Molybdenum, Zinc… Colours, coatings, stabilizers Chemical safety assessed through many regulations today - their applicability for REACH will be studied:  Chemical safety assessed through many regulations today - their applicability for REACH will be studied Performed already today through out Europe in different ways Performed on both substances and mixtures (= fertilizers) During handling of raw materials, production, storage and application at farm Controlling regulations include e.g.. Manufacturing sites under Seveso control (HNO3, NH3, H3PO4 etc) Manufacturing sites are generally IPPC plants (BREF for Ammonia, Acid and Fertilizers) Transport: Hazardous substances under ADR rules Use at the farm: Fertilizer legislation and the Nitrate Directive define conditions for approvable dosing and application at the farm Handling and use of Ammonium Nitrate regulated heavily due to it’s explosiveness Industry sector HSE Best Practises created for ensuring safe handling and use Fertilizer case:  Fertilizer case Back bones of importance: Matrix for IU is that possible Preparing CSA for preparation / mixture containing many substances with different ES’s and different thresholds values Looking at OEL’s arriving from ES’s and other sources How to cover the value chain from raw materials to end use with CSA’s – How many, how many details are needed? E.g. production, transport, storage, use Cooperation with farmers for determining appropriate control measures and understandable format for output For the case study: Criteria for CSA for complex preparations? Definition for coverage of a CSA – which are the critical exposures? Which scope can / should be covered by the same assessment?
