3 The Toxic Substances Control Act (TSCA) EPA is responsible for assuring that industrial chemicals for sale and use in the U.S. do not pose unacceptable risks to human health or to the environment. Enacted in 1976, TSCA provides EPA with broad authority to: Maintain inventory of existing chemicals (originally more than 60,000, now more than 80,000 substances) Gather information on new and existing chemical substances and mixtures Require testing of chemicals Screen and control unreasonable risks of new and existing chemicals Coordinate with other Federal agencies
4 North American Cooperation on Chemical Assessment and Management At Security and Prosperity Partnership (SPP) Summit in August 2007, President Bush, Canadian Prime Minister Stephen Harper and Mexican President Felipe Calderon committed to specific goals to: Enhance regulatory cooperation among Canada, Mexico, U.S. Accelerate and improve effectiveness of actions to safeguard health and environment Provide cost-effectiveness for business and government Retain national regulatory authority
5 US Commitments under SPP By the end of 2012: Assess and initiate needed action on the approximately 9,000 existing chemicals produced above approximately 10 tons/yr in the U.S. Posted two sets of HCs for a total of 151 chemicals. Includes organic High Production Volume (HPV) and Moderate Production Volume (MPV) chemicals Includes work under HPV Challenge MPV works builds off Canadian categorization effort Make and publicly release screening level decisions and initiate needed action
6 Existing Chemicals – National Program Chemicals Lead: Lead Renovation, Repair and Paint Rule Expand the R&R Rule to include child-occupied facilities Mercury Public process to address long-term management of non-Federal mercury stockpiles Mercury Switch SNUR Asbestos Updated “Current Best Practices for Preventing Exposure Among Brake and Clutch Repair Workers”
7 Managing Chemicals – Perfluorinated Chemicals PFOS Late 90’s, PFOS was detected in human and animal blood worldwide. 3M, the major global producer, reported concerns to EPA Late 90’s, 3M ceased production of PFOA EPA followed with a TSCA rule that requires any new use of PFOS be reviewed by EPA PFOA EPA initiated stakeholder process to develop needed information on sources and pathways of exposure and sought external scientific review on interim risk assessment In 2006, EPA sought and received commitments from 8 major PFOA manufacturers to reduce PFOA and related chemicals from emissions and product content by 95 percent no later than 2010 and to work towards eliminating emissions and product content by 2015
8 PFOS/PFOA Significant Reductions In August 2007, The U.S. Centers for Disease Control issued a report that: Documented significant reductions in human blood levels of PFOS and PFOA from 1999/2000 through in 2003/2004. The samples indicated that PFOS in human blood was reduced by 32% in while PFOA was reduced by 25% in this same period. The report concludes that the reductions are related to the discontinuation of industrial production of PFOS in 2002 and other changes brought about by EPA and related efforts by government and industry.
9 Nanotechnology Nanoscale materials (NMs) are chemical substances as defined by TSCA. NMs may have different toxicity and/or exposure characteristics than their “macro” counterparts NMs not on the TSCA Inventory are new chemicals and are subject to “new chemical” review by EPA prior to manufacture TSCA definition of new chemical is based on molecular identity, not on other characteristics EPA announced a “stewardship program” to handle existing chemical nanomaterials.
10 Nanomaterials Stewardship Program Needs include: Generate data needed to provide a sound scientific foundation for assessments Obtain better informed decision-making on new chemicals and realize oversight of “existing” chemical NMs Industry stewardship in the manufacture and use of new and existing chemical NMs Under the Basic Program Report available information on the engineered nanoscale materials they manufacture, import, process or use. EPA encourages participants to use the optional data submission form and worksheet, but participants may provide available data in any format. Under the In-Depth Program Participants will voluntarily develop data, including testing, over a longer time frame. Once potential participants are identified, EPA will facilitate a process leading to data development.
11 Community Action for a Renewed Environment (CARE) Reduce exposures to toxic pollutants through collaborative action at the local level. Help communities understand all potential sources of exposure to toxic pollutants. Work with communities to set priorities for risk-reduction activities. Create self-sustaining, community-based partnerships that will continue to improve the local environment.
14 Design for the Environment (DfE) The Design for the Environment (DfE) Program works in partnership with a broad range of stakeholders to reduce risk to people and the environment by preventing pollution. Focus Chemicals of concern Informed Substitution OPPT technical tools and expertise Considerations Business client Multi-stakeholder participation Business realities Potential benefits for industry and the environment
