TSCA is our nation’s primary chemical management law. This law requires EPA to evaluate the risks associated with exposure to existing chemicals using the best available science then take action to reduce or eliminate any unreasonable risks identified. The agency issued a final risk evaluation for HBCD in September 2020 showing unreasonable risks to the environment and workers under certain conditions of use. EPA is now moving to risk management for this chemical, the next step in the process required by TSCA.

There are several actions EPA can take under TSCA to address unreasonable risks including banning a chemical; restricting the manufacturing, processing, distribution, use, or disposal; requiring warning labels /testing; and requiring manufacturers to notify distributors of any unreasonable risks. EPA has up to one year after issuing a final risk evaluation to propose risk management actions followed by a public comment period and final rule.
