Tracking TSCA Chemical Risk Evaluations
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.
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.
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.
