Closing the Gaps – Changes in progress:

1. DBI 0830117 From Cradle-to-Grave at the Nanoscale: Gaps in US Regulatory Oversight along the Nanomaterial Life Cycle • Through a rigorous review of US federal EHS regulations, and governmental, NGO, and academic reports, this research identifies significant gaps in regulatory oversight across the ENM life cycle: • Exemptions & Thresholds • Data, Uncertainty, and the Burden of Proof • Risk Re-assessment • Post-Market Risk Management • Confidential Business Information (CBI) • Limited Resources • Closing the Gaps – Changes in progress: • Proposed TSCA reform: Limiting CBI, Manufacturer minimum testing, Improving EPA authority to require testing • Nano-specific SNURs (CNTs, several ENM categories) • Proposed definition for ‘special substance characteristics’ – to differentiate between nano and non-nano forms of materials • Additional Recommendations: • Reduce End-Of-Life gaps – rapid development of monitoring and control technologies, proactive/preventative risk mitigation • Enhance collaborative efforts, promote product stewardship • Increased disclosure & sharing of product and risk information Beaudrie, Kandlikar, Satterfield 2012.
