Title: ●Regulation of Persistent, Bioaccumulative, and Toxic Chemicals Under TSCA Section 6(h) 
Abstract:

Section 6(h) of the Toxic Substances Control Act directs EPA to issue regulations under section 6(a) for certain persistent, bioaccumulative, and toxic chemical substances that were identified in the 2014 update of the TSCA Work Plan. These regulations must be proposed by June 22, 2019, and issued in final form no later than eighteen months after proposal. Section 6(h) further directs EPA, in selecting among the available prohibitions and other restrictions in TSCA section 6(a), to address risks of injury to health or the environment and reduce exposure to the chemical substances to the extent practicable. EPA must develop an exposure and use assessment, but the statute explicitly states that a risk evaluation is not required for these chemical substances. EPA has identified five chemical substances that meet the statutory criteria in TSCA section 6(h) and that have not been designated as priorities for risk evaluation pursuant to TSCA section 6(h)(5). These chemical substances are: decabromodiphenyl ether; hexachlorobutadiene; pentachlorothiophenol; phenol, isopropylated phosphate (3:1), also known as tris(4-isopropylphenyl) phosphate; and 2,4,6-tris(tert-butyl)phenol. Decabromodiphenyl ether is a flame retardant that has been widely used in textiles, plastics, adhesives and polyurethane foam. Hexachlorobutadiene is produced as a byproduct in the production of chlorinated solvents and has also been used as an absorbent for gas impurity removal and as an intermediate in the manufacture of rubber compounds. Pentachlorothiophenol is also used in the manufacture of rubber compounds. Phenol, isopropylated phosphate (3:1) is a flame retardant and is also used in lubricants and hydraulic fluids and in the manufacture of other compounds. 2,4,6-Tris(tert-butyl)phenol is an antioxidant that can be used as a fuel or lubricant and as an intermediate in the manufacture of other compounds.
