On June 28, 2019, the U.S. Environmental Protection Agency (EPA) released the draft risk evaluations for cyclic aliphatic bromide cluster (HBCD) and 1,4-dioxane, two of the first ten chemicals undergoing risk evaluation under the amended Toxic Substances Control Act (TSCA).  In its June 28, 2019, press release, EPA states in the draft risk evaluation for HBCD, it did not find unreasonable risk to the general population, consumers, workers, or the environment.  According to EPA, in the draft risk evaluation for 1,4-dioxane, EPA did not find unreasonable risk to the environment, but the data “show there could be unreasonable risks to workers in certain circumstances.”  EPA states:  “It is important to note that for the general population, including children, environmental statutes administered by EPA such as the Clean Air Act, the Safe Drinking Water Act, the Clean Water Act, and the Resource Conservation and Recovery Act, adequately assess and effectively manage risks from 1,4-dioxane.”On Monday, July 1, 2019, EPA will publish a Federal Register notice announcing the availability of the draft risk evaluations and beginning a 60-day comment period.  The draft risk evaluations will be peer reviewed by the Science Advisory Committee on Chemicals (SACC) on July 29- August 2, 2019.  SACC will hold a preparatory virtual meeting to discuss the scope and clarity of the draft charge questions on July 10, 2019.SEE: https://www.natlawreview.com/article/epa-releases-draft-risk-evaluations-hbcd-and-14-dioxane
