Draft Risk Evaluation for Cyclic Aliphatic Bromide Cluster (HBCD)

Below are the draft risk evaluation and supporting documents for HBCD and a fact sheet on understanding the risk evaluation of HBCD. Read the Federal Register notice announcing the availability of the draft risk evaluation.

In the June 2019 draft risk evaluation of HBCD, EPA made the following initial determinations on risk. These initial determinations may change as our assessments become more refined through the public and peer review process.

  • No unreasonable risks for the general population, including consumers and children. HBCD is no longer domestically manufactured or imported in the U.S. and has been replaced by other chemicals and calculated risk estimates are below levels of concern.
  • No unreasonable risks to workers or occupational non-users. Again, HBCD is no longer domestically manufactured or imported in the U.S. and has been replaced by other chemicals. The use of HBCD does not present unreasonable risks to workers and applies to both those workers who come in direct contact with HBCD, as well as those who use the chemical but do not come in direct contact.
  • No unreasonable risk to the environment. For all the conditions of use included in the draft risk evaluation, EPA found no unreasonable risks to the environment from HBCD.

The draft risk evaluation is available for public comment until August 30, 2019 in docket EPA-HQ-OPPT-2019-0237. This public comment period is an opportunity to submit any additional information to assist EPA in issuing a final risk evaluation for HBCD. EPA will consider all comments on the draft risk evaluation when developing a final risk evaluation.
