Tracking TSCA Chemical Risk Evaluations

Posted on 1/19/2021 by Roger Marks

EPA has now completed all ten of its first scheduled chemical risk evaluations required under TSCA, as amended by the Frank R. Lautenberg Chemical Safety for the 21st Century Act or LCSA.

The First Ten 

EPA released a list of the first ten chemicals to undergo risk evaluation under the reformed TSCA process five years ago, in Winter 2016.

Scope documents for the first ten TSCA chemical risk evaluations were released in July 2017. 

Chemical name CASRN Latest EPA Action
1, 4 Dioxane 123-91-1 Final Risk Evaluation
1-bromopropane (1-BP) 106-94-5 Final Risk Evaluation
Asbestos (Part 1: Chrysotile Asbestos) 1332-21-4 Final Risk Evaluation
Carbon Tetrachloride  56-23-5 Final Risk Evaluation
Cyclic Aliphatic Bromide Cluster (HBCD) 25637-99-4, others Final Risk Evaluation
Methylene Chloride (MCL) 75-09-2 Final Risk Evaluation

Pigment Violet 29 (PV29) 81-33-4 Final Risk Evaluation
Trichloroethylene (TCE) 79-01-6 Final Risk Evaluation

In addition to the ten final risk evaluations EPA issued, the agency also created new restrictions for a handful of persistent, bioaccumulative toxic (PBT) chemicals that the law called out for immediate action.
