REACH Provisions  REACH objectives: – Protection of human health and environment – Development of hazards, use conditions and exposure information for existing substances – Compulsory sharing of information to ensure competitiveness of EU chemical industries  Reduce animal testing (in vitro, QSAR, read-across)  Responsibility for hazard information shifts from the government to the industry  Sustain REACH-IT portal for communication among registrants

5. REACH Regulation  Evaluate existing (EINECS) substances (30,000) 2010 - 2018  Compile registration technical dossiers on EINECS substances – IUCLID 5  Reduction of testing requirements for new chemicals 1 – 10 tons  QSAR and alternatives for animal studies accepted, also using read-across

6. REACH: phase-in substances Tiered approach for registration 1.2,600 substances > 1,000 MT + CMR 2.2,900 substances 100 – 1,000 MT 3.4,600 substances 10 – 100 MT 20,000 substances 1 – 10 MT There will be one pre-registration and consortia building opportunity (SIEF formation) before data collection starts.

7. REACH: Exemptions  Substances under PPORD are exempted for 5 – 10 years  medicinal products including intermediates  waste  foodstuffs  pesticides  radioactive substances  substances in transit - customs supervision  cosmetics  Polymers are exempted (for the moment).

13. 100 – 1,000 t/y (Annex IX)  Additional physico-chemical  Further repeated dose toxicity  Long-term aquatic toxicity  Degradation and e-fate behaviour  Terrestrial toxicity  Rough costs: € 550,000 – € 1,000,000 minimum $825,000

14. > 1,000 MT/y (Annex X) Only after approval by authorities:  Additional long-term toxicity  Additional long-term aquatic toxicity  Additional terrestrial toxicity  Rough costs: € 1,300,000 mimimum $2,000,000

15. Pre-registration Approaches To be done between 1 June and 1 December 2008

16. What is needed to pre-register a substance :  Registration number (EINECS/CAS)  Chemical name (IUCLID or CAS)  Registrant/Contact information  Registration deadline and tonnage  Information on similar substances for QSAR and potential read-across  Must submit via REACH-IT portal

17. Prepare for SIEF activities  Determine value of data you own  Decide on required role in consortia (lead, active or passive member)  Decide on sharing company confidential information (composition data, use information)  Advise downstream users of REACH conformance

18. Test plan:  Data gaps based on volume needs (Annex VII + VIII)  Data needs based on scientific or use considerations for Annex IX + X end-points  Data needs based on the outcome of the CSA/CSR  What can be waived using Annex XI

19. After Pre-registration  Companies who have pre-registered a substance will automatically become listed on the pre-SIEF page (REACH-IT) of this substance.  To initiate discussions after pre-registration, a pre-registrant can volunteer on the pre-SIEF page to become SIEF formation facilitator.  ECHA will publish by 1 January 2009, a list of pre-registered substances on its website. The list will comprise of all substances that have been pre-registered by 1 December 2008. For each substance the following information is displayed:  Substance identification: EINECS number, CAS number and names of the substance  Substance identification of the similar substances, if applicable  The first envisaged registration deadline

20. Registration Technical Dossier:  Annex VII: ± € 3,500  Annex VIII: ± € 15,000  Annex IX: ± € 30,000  Annex X: ± € 39,000 Based on setting the economic values and making robust summaries of one study per endpoint. The estimated time for a substance imported/produced in Europe above 100 MT, is a worst case estimate as only data from Annex VII and VIII are compulsory to report.

21. Annex XI: what’s in it?  Testing does not appear scientifically necessary –Use existing (non-GLP) data –Use historical human data –Weight of evidence –(Q)SAR possibilities –In vitro methods –Grouping and read-across  Testing is technically not possible  Substance-tailored exposure-driven testing

22. REACH and new chemicals (non-phase-in substances)  Changing of notification levels –< 1 ton: exempt –1-10 tons: limited testing (Annex VII) –> 10 tons: full package (Annex VII + VIII) plus a test plan if > 100 tons  Introduction of in-vitro testing  Introduction of computer models  Introduction of read-across
