The Environmental Protection Agency is proposing to extend the reporting deadline for the Toxic Substances Control Act (TSCA) Health and Safety Data Reporting Rule. EPA is seeking public comment on the proposed action, including any considerations or concerns that stakeholders may have regarding the proposed extension of the reporting deadline. The proposed extension is intended to delay the compliance burdens associated with the one-time reporting rule while EPA considers potential modifications to the regulation and to make consequent changes to the electronic reporting application in EPA’s Central Data Exchange (CDX) necessary to collect the required information.
