In early June, 2016, the US Congress approved the Frank R Lautenberg Chemical Safety for the 21st Century Act which details major reforms to the Toxic Substances Control Act (TSCA). While the bill itself is a compromise reached following several revisions, it does contain some significant changes, including:
- Increasing the EPA’s authority to require testing and mandating the reduction and replacement of animal testing “where scientifically reliable alternatives exist.”
- A new prioritisation structure and requirement for testing existing chemicals under reasonable deadlines, regardless of cost.
- Removing the current requirement for the EPA to implement the “least burdensome” regulations.
- Establishment of a health-based safety standard
- Requirement of science-based decisions that are founded on Weight of Evidence (WoE)
- Allowing the collection of fees that go directly to the EPA.
Enactment of the bill by the EPA will occur following President Obama’s signature which is expected imminently.
