TSCA Existing Chemicals & Regulatory HPV Support
US EPA's Toxic Substances Control Act (TSCA) regulations require EPA to address pollution prevention, hazard and exposure assessment, risk assessment, and risk management for chemicals in commerce. Under TSCA, EPA is charged with the responsibility of assessing the safety of chemicals and to act if there are significant risks to human health or the environment. For “existing chemicals,” EPA has programs to address risk assessment and risk reduction measures, data collection and screening, and public access to chemical data. Current actions include identification of TSCA Workplan Chemicals, specific chemical risk management actions, issuance of new rules for chemical data reporting (CDR) and electronic reporting, final rules under TSCA section 4(a) requiring testing for orphan High Production Volume (HPV) chemicals, and updates to the Interagency Testing Committee (ITC) Priority Chemical Lists. EPA has a separate program for "new chemicals."
