Draft scope documents for high-priority chemicals undergoing risk evaluation


In December 2019, EPA designated 20 High-Priority substances to undergo risk evaluation under the Toxic Substances Control Act (TSCA). The scope documents for 13 of these substances are available below. Upon publication of the Federal Register notice, EPA will accept public comments on the draft scopes for 45 days. Comments may be submitted to the docket relevant to this action (EPA-HQ-OPPT-2019-0131), or to the individual dockets for each of the chemicals. Additionally, the agency will soon release and accept public comments on the seven remaining draft scope documents.
