The EPA uses existing regulatory frameworks such as the Toxic Substances Control Act (TSCA) and the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) to manage nanomaterials. Under TSCA, manufacturers must notify the EPA before producing new nanomaterials, allowing for an assessment of potential risks. Similarly, under FIFRA, pesticides containing nanomaterials must be registered and evaluated for safety.
