Problem Formulations for the Risk Evaluations To Be Conducted for 
the First Ten Chemical Substances Under the Toxic Substances Control 
Act, and Application of Systematic Review in TSCA Risk Evaluations; 
Extension of Comment Period

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice; extension of comment period.

-----------------------------------------------------------------------

SUMMARY: EPA issued a notice in the Federal Register of June 11, 2018, 
opening a comment period on problem formulations for the risk 
evaluations to be conducted for the first ten chemical substances 
listed in Table 1, along with a document entitled Application of 
Systematic Review in TSCA Risk Evaluations. This document extends the 
close of the comment period on the problem formulations for an 
additional 21 days, from July 26, 2018 to August 16, 2018. This comment 
period is being extended in response to requests received by the 
Agency. The Agency is also taking comments on the document entitled 
Application of Systematic Review in TSCA Risk Evaluations in 
conjunction with this comment period and not through a separate comment 
period. The systematic review document includes a structured process of 
identifying, evaluating and integrating evidence for both the hazard 
and exposure assessments developed during the TSCA risk evaluation 
process. This document may be revised periodically. EPA welcomes public 
input on the document.

DATES: Comments, identified by docket identification (ID) numbers 
identified in Table 1, must be received on or before August 16, 2018.

ADDRESSES: Follow the detailed instructions provided under ADDRESSES in 
the Federal Register document of June 11, 2018 (83 FR 26998) (FRL-9978-
40).

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.

[[Page 38692]]

    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.
