What are the Main Requirements for Nanomaterials under TSCA?
1. [Pre-Manufacture Notification (PMN)](): Before manufacturing or importing new nanomaterials, companies must submit a PMN to the EPA at least 90 days in advance. This notification includes data on the chemical identity, production volume, byproducts, use, and exposure, among other things.
2. Significant New Use Rules (SNURs): The EPA can issue SNURs for nanomaterials, which require companies to notify the EPA before using a nanomaterial in a way that is considered a "significant new use." This allows the EPA to evaluate the potential risks and, if necessary, take action to manage those risks.
3. [Risk Evaluation](): The EPA conducts risk evaluations to determine whether a nanomaterial poses an unreasonable risk to health or the environment. This evaluation considers factors such as toxicity, exposure, and the potential for release into the environment.
