TITLE: Regulation of Persistent, Bioaccumulative, and Toxic Chemicals Under TSCA Section 6(h); 
Extension of Comment Period  
AGENCY: Environmental Protection Agency (EPA)  
ACTION: Notice; extension of comment period  
SUMMARY: In the Federal Register of 29 July 2019, EPA proposed a rule concerning certain 
persistent, bioaccumulative, and toxic chemicals i dentified pursuant to section 6(h) of the Toxic 
Substances Control Act (TSCA). These five chemicals are: decabromodiphenyl ether; phenol, 
isopropylated phosphate (3:1), also known as tris(4 -isopropylphenyl) phosphate; 2,4,6 -tris(tert -
butyl)phenol; hexachlo robutadiene; and pentachlorothiophenol. The proposed rule, if finalized, 
would restrict or prohibit manufacture (including import), processing, and distribution in commerce 
for many uses of four of these five chemical substances. EPA evaluated the uses of 
hexachlorobutadiene and proposed no regulatory action. For the other four, the proposal included 
recordkeeping requirements. Additional downstream notification requirements were proposed for 
phenol, isopropylated phosphate (3:1). This document extends the comment period for 31 days, 
from 27 September 2019, to 28 October 2019.  
DATES: Comments, identified by docket identification (ID) number EPA - HQ-OPPT-2019-0080 
must be received on or before 28 October 2019.
