The EPA currently reviews new chemical substances manufactured or processed as nanomaterials prior to introduction into the marketplace to ensure that they are safe. For the first time, the agency is proposing to use the Toxic Substances Control Act to collect existing exposure and health and safety information on chemicals currently in the marketplace when manufactured or processed as nanoscale materials.
The proposal would require companies that manufacture or process chemical substances as nanoscale materials to notify EPA of:
- certain information, including specific chemical identity;
- production volume;
- methods of manufacture; processing, use, exposure, and release information; and, available health and safety data.
