Now Final: 20 High-Priority Chemicals for TSCA Risk Evals
Under TSCA section 6(b), EPA is required to evaluate the risks associated with the conditions of use of all the chemicals on the TSCA inventory. Of the more than 80,000 listed on the TSCA inventory, 40,655 are active in commerce (meaning they are currently manufactured, imported, or processed in the US).
In August 2019, EPA proposed these first 20 high-priority chemicals to undergo risk evaluations under the reformed chemical law. Under the Frank R. Lautenberg Chemical Safety for the 21st Century Act (LCSA), which amended TSCA, EPA is required to be working on twenty risk evaluations at any one time.
Here’s EPA’s final list of the first 20 High-Priority chemicals:
|Butyl benzyl phthalate (BBP)||85-68-7|
|Dibutyl phthalate (DBP)||84-74-2|
|Di-ethylhexyl phthalate (DEHP)||117-81-7|
|Di-isobutyl phthalate (DIBP)||84-69-5|
|4,4′-(1-Methylethylidene)bis[2, 6-dibromophenol] (TBBPA)||79-94-7|
|Phosphoric acid, triphenyl ester (TPP)||115-86-6|
|Tris(2-chloroethyl) phosphate (TCEP)||115-96-8|
* 1,3,4,6,7,8-Hexahydro-4,6,6,7,8,8-hexamethylcyclopenta [g]-2-benzopyran
Details about each high-priority chemical substance is available at EPA's website.
(See EPA's Notice in the Federal Register)
Proposing a chemical as a “high-priority” chemical does not mean that the chemical necessarily poses an unreasonable risk to human health or the environment. It means that EPA has determined that the chemical may pose such a risk—and initiates the official risk evaluation process.
What’s Next for TSCA Risk Evaluations?
Now that final designations have been made for the first twenty high-priority chemicals, EPA will begin the process of evaluation the risks posed by these chemical substances.
To evaluate each chemical, EPA will consider:
- Hazard and exposure potential
- Persistence and bioaccumulation
- Potentiallly exposed or susceptible subpopulations
- Storage of the chemical near drinking wate sources
- Conditions of use or significant changes in conditions of use
- Product volume or significant changes in production volume
- Other risk-based criteria EPA believes is relevant
Master TSCA ComplianceThe Toxic Substances Control Act (TSCA) is complex and enforcement is stringent, making a comprehensive understanding of the rules critical for compliance. The law has broad applicability, subjecting all companies that “manufacture, use, process, distribute, import, or export chemical products” to complex reporting and management requirements.
