EPA recently completed risk evaluations and established new regulatory management programs for five PBT chemical substances. For many of these chemicals, EPA will prohibit all manufacture, import, processing, and distribution in commerce.
The five new rulemakings illustrate EPA’s broad authority under TSCA to restrict how chemicals are made and used in order to protect human health and the environment. Read on for details about new restrictions EPA has put in place for these chemicals.
The five PBT chemicals for which EPA issued new rules are:
Pentachlorothiophenol (PCTP):- EPA will prohibit all manufacture, import, processing, and distribution in commerce of PCTP and PCTP containing products or articles for any use, unless PCTP concentrations are at or below 1% by weight.Pentachlorothiophenol or PCTP (CASRN 133-49-3) is used in rubber manufacturing, including as an ingredient in the rubber core of golf balls.
Hexachlorobutadiene (HCBD):-New TSCA regulations prohibits all manufacture, import, processing, and distribution in commerce of HCBD and HCBD containing products or articles. A halogenated aliphatic hydrocarbon, HCBD is produced as a byproduct during the manufacture of other chemicals, including some for which EPA recently completed risk evaluations—PCE, TCE, and Carbon Tetrachloride (Carbon Tet).
Decabromodiphenylether (DecaBDE):-TSCA update fordecaBDE prohibits all manufacture, import, processing, and distribution in commerce of decaBDE and products or articles containing decaBDE, with some exclusions.A handful of states already ban decaBDE, including Washington, Maine, Oregon, Vermont, and Maryland. The largest commercial producers and suppliers of decaBDE reached an agreement with EPA in 2009 to phase out use of the chemical by the end of 2013.
Phenol, Isopropylated Phosphate 3:1 (PIP 3:1):- TSCA update prohibits processing and distribution in commerce of PIP (3:1) and products that contain it, with specific exclusions. PBT TSCA UpdateProhibits the release of PIP 3:1 to water during manufacturing, processing, or distribution. Commercial users are required to follow existing regulations and best practices to release to the water during use. PBT TSCA Update also includes notification and recordkeeping requirements for persons who manufacture the chemical, process it, or distribute it in commerce.PIP (3:1) (CASRN 68937-41-7) is a versatile chemical. It can be used as a plasticizer, a flame retardant, or an anti-wear additive or an anti-compressibility additive. It is used for various purposes in hydraulic fluids, lubricants, industrial coatings, adhesives, sealants, and plastic articles,prop 65 regulations.
2, 4, 6-tris(tert-butyl)phenol (2, 4, 6-TTBP):- EPA prohibits the distribution in commerce of 2,4,6-TTBP and products containing 2,4,6-TTBP at concentrations above 0.3 percent in any container with a volume less than 35 gallons for any use and above 0.3 percent by weight for use as an oil lubricant or additive, regardless of container size.2,4,6-TTBP is used as an intermediate/reactant in chemical processing, to treat fuel in refineries and fuel facilities, in motor vehicle and machinery maintenance and repair, and as a liquid lubricant and grease additive.
