What are the key requirements of TSCA for catalytic substances?
Chemical Safety Review: Before manufacturing or importing a new chemical substance, companies must submit a premanufacture notice (PMN) to the EPA. The EPA then evaluates the potential risks associated with the substance. Inventory Listing: All existing chemical substances must be listed on the TSCA Inventory. If a catalyst or any other substance used in catalysis is not listed, it cannot be legally manufactured or imported until it is added to the inventory. Risk Evaluation: The EPA conducts risk evaluations to determine whether a chemical substance poses an unreasonable risk to health or the environment. This includes evaluating exposure scenarios in catalytic processes. Risk Management: Based on the risk evaluation, the EPA can impose restrictions or bans on certain chemical substances used in catalysis to mitigate identified risks.
