Timelines
Date Activity
November 2022 Anticipated publication of the final screening assessment and proposed risk management approach.
November 6, 2021 Publication and start of 60-day public comment period on the Draft Screening Assessment for the Flame Retardants Group (including follow-up activities for TBOEP and TDBDPB) and the Risk Management Scope for TPHP, BPDP, BDMEPPP, IDDP, IPPP and TEP. The related notice was published in the Canada Gazette, Part I: Vol. 155, No. 45.

Background

Three other substances were identified as being a part of the Flame Retardants Group at the outset of the third phase of the CMP. These substances were subsequently determined to be of low concern to both human health and the environment, through a separate approach. The conclusions for CAS RNs 26446-73-1, 68527-01-5 and 68527-02-6 are provided in the Final Screening Assessment for the Rapid Screening of Substances with Limited General Population Exposure.
