SUPPLEMENTARY INFORMATION:

This document extends the public comment period for certain chemicals established in the

Federal Register

document of June 11, 2018 (83 FR 26998) (FRL- 9978-40). In that document, a public comment period opened on EPA's problem formulation documents for the first 10 chemical substances undergoing risk evaluation under the Toxic Substances Control Act (TSCA) in Table 1 and the document entitled

Application of Systematic Review in TSCA Risk Evaluations.

EPA is hereby further extending the comment period for the problem formulation, and the document entitled

Application of Systematic Review in TSCA Risk Evaluations,

which was set to end on July 26, 2018, to August 16, 2018.

Although the comment periods will end on August 16, 2018, EPA will try to consider any additional comments received after this date. However, given the need to peer review the draft risk evaluations, the peer reviewers may not receive public comments submitted late. There will be an additional comment period following the publication of each of the draft risk evaluations.
