Impacts of the European Commission’s REACH Proposal on Risk Assessment Joel A. Tickner, ScD and Ken Geiser, PhD Lowell Center for Sustainable Production University of Massachusetts Lowell joel_tickner@uml.edu
Europe and the US – Similar Problems • Lack of toxicity/exposure information on chemicals in commerce • Unequal treatment of new/existing chemicals • Slow chemical by chemical risk assessment process, burden on government • Lack of incentives to stimulate development and implementation of safer substitutes • Increasing evidence of health effects • Lack of integrated and comprehensive approach to chemicals management
The REACH Proposal • In February of 2001, the European Commission issued a White Paper on the Future of Chemicals that proposed a major new policy called REACH • REACH: • Registration • Evaluation • Authorization of • CHemicals
The REACH Proposal • A duty of care on chemical producers, users, and importers for studying risks and safety • A European-wide approach to chemicals policy – protect internal market • Substitution of chemicals of very high concern - innovation in safer chemicals • Bridge knowledge gap between new and existing chemicals – develop information on all chemicals. • Reduction in animal testing • Promotion of a non-toxic environment – the “generational goal”
Components of REACH • Registration – testing, data collection, and assessment of all chemicals and supply chain information • Evaluation of risks of chemicals used in greatest quantity and of highest concern • Accelerated risk management for chemicals of concern • Authorization for substances of highest concern. • Establishment of a new central administrative agency
Registration • Essentially a notification process • All producers and importers of substances produced over 1m ton/year (about 30,000 substances) • Phased in over 3 yrs, 6 yrs, and 11 yrs • Pre-registration, consortia establishment • Exemptions for R&D, intermediates, polymers, others • Current New Chemicals are considered registered • Requirement to submit new data
Registration requirements • Base information – identity, information on manufacture and uses, proposed classification/labeling, • Chemical safety assessment/guidance on safe use (over 10 tons) – risk assessment for all identified uses • Additional tiered testing/information – requirements – flexibility • Requirement to consult database/authorities before testing • Required data sharing/compensation – Substance Information Exchange Forum
Evaluation • Essentially a risk screening process • Two types: standard and priority • Standard: minimize duplicative testing for high production volume substances • Priority: review of registration to identify additional information needs (focus on high volume/high concern plus intermediates and randomly selected substances) • Requirement to consult other Member States before requiring additional testing • Can lead to risk management recommendations.
Authorization • Essentially a use restrictions process • Applies to chemicals of very high concern – CMRs 1&2, PBTs, VPVBs, and other high concern substances • Requirement to request authorization for high concern chemicals – timelines (includes use and incorporation into articles) • Consideration of socio-economic benefits, alternatives, controls in place (safe use) • Can be subject to conditions/time limited • Community/Member State authorizations
Restrictions process • A “safety net” – for Community wide protection • Member State proposal for restriction • Preparation of risk assessment and socio-economic assessment • Commission decision • Can specify types of restrictions • Time limited process
Role of new chemicals agency • Database on chemicals under registration/ authorization • Completeness check of registration dossiers • Risk assessment/socio-economic analysis for Community authorizations • Risk and socio-economic analysis for restrictions • Forum for exchange of information on enforcement • Maintenance of much expertise in Member States
EU Legislative Process • White Paper • Draft legislation • Comment Period • Final Commission proposal • First Reading Parliament/Council • Second Reading Council/Parliament (time limited) with Commission debate • Conciliation (time limited)
Impacts of REACH on Risk Assessment – new data and initial burden on industry • Burden on industry to come up with test data or equivalent information • Availability of test data for most existing substances • Ability to use surrogates (QSAR, category approach, alternatives) if satisfactory • Burden on industry to provide risk assessment and risk management recommendations for all identified uses according to guidance • New supply chain use and exposure data
New government risk assessment responsibilities • Development of good IT system for collecting, analyzing, and public access to data • Data on some 11,000 chemicals over 11 years • Protecting CBI • Spot checks of dossiers for completeness • Member States perform evaluation of risk assessments for certain higher concern substances (high volume, toxicity concerns) • For additional data/risk assessment needs • For risk management recommendations • Determination of new chemicals of concern for which registration is warranted – intermediates
Need for rapid screening and assessment tools • Need for tools to rapidly characterize chemical hazards, exposures and risks • Traditional risk assessment methods won’t be quick enough • Need effective prioritization schemes • Need indicators of which chemicals seem to be of higher concern • One option is establishment of list of “chemical categories” • Opportunities to reduce registrations by encouraging non-registration of chemicals of concern. • Need tools that can be given to industry to help then internalize good assessment practices
Rapid chemicals review under TSCA Section 5 • Multi-disciplinary, multi-step hazard and risk review throughout lifecycle • Rapid chemical assessment using available data (SAR, surrogates, etc.) • Conservative assumptions in face of data gaps • Build on database/experience of 30,000 new chemicals analyzed
Information Needs in REACH • Need for good process/facility/supply chain level materials accounting information • Materials not efficiently managed (what you can’t measure you can’t manage) • Identifies opportunities for greater efficiency and supply chain uses and places for exposure reduction and substitution • Need good metrics to measure progress • Need good information on alternatives to problem substances • Market pressures from good information on alternatives
The big risk assessment challenge in REACH – alternatives assessment • Chemical changes mean process changes • Potential for risk trade-offs (community, occupational) • Defeats goals of REACH if companies switch to other problem substances • No clear cut tools for comparative assessments • P2OASys – UMASS Lowell • German, Swedish, OSPAR, Nordic Substitution methodologies • University of TN Risk Ranking tool/CTSA method • PBT Profiler • A challenge to develop procedures for substitution assessment
Goals of a substitution assessment method • Compare toxicity, physical hazards and other trade-offs at process and lifecycle levels • Identify key criteria for avoidance (ie PBT) • Allow flexibility to adapt to particular chemical, use • Allow use of expert judgment • Number scores are easy but hide information • Be simple and clear enough so that firms and regulators can use • Outline a clear process/guidelines for “substitution thinking”
A possible process for substitution assessment • Problem Identification • Identification and development of a range of alternatives (chemical, non-chemical) • Identification of the consequences of the alternatives • Comparison of the alternatives • Decision • Implementation • Evaluation of the results/reevaluation
TSCA Section 5: Guidance Towards Safer Chemicals • Attempt to get safer chemicals to market to replace existing problem ones • Pre-manufacture pollution prevention review of substances and syntheses • Green chemistry initiatives • Informal discussion with manufacturers • Agency going from gatekeeper to encouraging safer chemicals and processes
Conclusions • REACH will require development of new risk assessment tools • For rapid assessment • For alternatives assessment • Without these will have collection of data • REACH will require development of clear guidance on how to assess chemicals, substitutes, and trade-offs • REACH will require tools to understand risk reduction activities/progress towards goals • To be more effective, REACH needs to include more data on process level use and exposure
Final thoughts… • If REACH internalizes holistic consideration of chemical lifecycle risks and alternatives then it has achieved some measure of success • Too little attention has been paid to substitution and analysis of alternatives • Equally applicable with what to do about HPV/VCCEP in the US • An opportunity to guide manufacturers towards safer chemicals and syntheses.
