View Rule

Section 6(h) of the Toxic Substances Control Act (TSCA) 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 and, in selecting among the available prohibitions and other restrictions in TSCA section 6(a), to address risks of injury to health or the environment that the Administrator determines are presented by the chemical substances and reduce exposure to the chemical substances to the extent practicable. As required under TSCA section 6(h), EPA developed an exposure and use assessment, but the statute explicitly states that a risk evaluation is not required for these chemical substances. EPA intends to take final action on a proposed rule that published on July 29, 2019, to address the following persistent, bioaccumulative, and toxic chemicals identified pursuant to TSCA section 6(h): decabromodiphenyl ether; phenol, isopropylated phosphate (3:1), also known as tris(4-isopropylphenyl) phosphate; 2,4,6-tris(tert-butyl)phenol; pentachlorothiophenol; and hexachlorobutadiene. Although all chemical substances were addressed in a single proposed rule, EPA intends to address these chemical substances in separate final actions. As such, EPA has split the original Regulatory Agenda entry (RIN 2070-AK34) into separate Regulatory Agenda entries. This particular entry is for phenol, isopropylated phosphate (PIP) (3:1), also known as tris(4-isopropylphenyl) phosphate. PIP (3:1) is a flame retardant and is also used in lubricants and hydraulic fluids and in the manufacture of other compounds. EPA proposed to prohibit the processing and distribution in commerce of the chemical substance, and products containing the chemical substance with several exceptions; prohibit releases to water from the non-prohibited processing, distribution in commerce, and commercial use activities. Persons manufacturing, processing, and distributing PIP (3:1), and products containing PIP (3:1), in commerce would be required to notify their customers of these restrictions, and EPA proposed to require affected persons to maintain, for three years from the date the record is generated, ordinary business records that demonstrate compliance with the restrictions, prohibitions, and other requirements. For information about the other chemical substances, see the Regulatory Agenda entries identified as RIN 2070-AK34 (decabromodiphenyl ether); RIN 2070-AK59 (2,4,6-tris(tert-butyl)phenol); RIN 2070-AK60 (pentachlorothiophenol); and hexachlorobutadiene (RIN 2070-AK61).
