EPA is developing a rulemaking under sections 8(a) and (d) of the Toxic Substances Control Act (TSCA) to establish reporting requirements based upon a chemical’s status in the Risk Evaluation/Risk Management (RE/RM) lifecycle, and to update the reporting requirements under the Chemical Data Reporting (CDR) regulation (40 CFR part 711). TSCA section 8(a) provides EPA with the authority to require manufacturers and processors to report information known to or reasonably ascertainable by them, including information on chemical identity and structure, manufacture, use, exposure, disposal, and health and environmental effects, and to maintain records of such information. TSCA section 8(d) provides EPA with the authority to require manufacturers, processors, and distributors to submit health and safety study information to the Agency. EPA is developing this rule to obtain information about potential hazards and exposure pathways related to certain chemicals, particularly occupational, environmental, and consumer exposure information. This information will inform prioritization, risk evaluation, and risk management of the chemical substances under TSCA section 6.
