Certain Organic Flame Retardants substance grouping

Certain organic flame retardant substances are among those identified as priorities for action for the second phase of the Chemicals Management Plan (CMP). The selection of these organic flame retardant substances for action was based on the categorization process completed in 2006, evaluations by the New Substances Program suggesting potential ecological and human health concerns for certain organic flame retardant substances not on the Domestic Substances List (DSL), and new information received as part of the first phase of the CMP.

Draft Screening Assessments, State of the Science Reports and Risk Management Scopes

In October 2016, six draft screening assessments, and two draft state of the science reports, which collectively consider ten substances were released and the related Notices were published in the Canada Gazette, Part I: Vol. 150, No. 41 - October 8, 2016 (PDF Version - 1,746 K).

The draft screening assessments of EBTBP, Melamine, TDCPP and TCP propose to conclude that none of these substances is harmful to the environment or to human health as set out in section 64 of CEPA 1999.

The draft state of the science reports of ATE, TBB and TBPH indicate that current quantities in use in Canada are unlikely to pose a risk to the environment or human health. These substances had been previously evaluated under the New Substances Program and were suspected to meet various section 64 criteria (based on the pre-market projections of use quantities). Even though the results of the current draft state of the science reports indicate that current levels are unlikely to pose a risk, the substances are commercial alternatives to other flame retardants and there is a possibility that quantities could increase in Canada. These substances will therefore continue to be subject to the New Substances Provisions of CEPA 1999 and to any associated Ministerial Conditions, to require pre-market notification of any new entrants importing or manufacturing these substances and to allow risk management measures to be put in place, should they be deemed necessary.

The draft screening assessments of DP and DBDPE propose to conclude that these substances are harmful to the environment as set out in paragraph 64 (a) of CEPA 1999, but that they are not harmful to the environment on which life depends, or to human health as set out in paragraphs 64 (b) and 64 (c) of the Act respectively.

The draft screening assessment of TCPP proposes to conclude that this substance is not harmful to the environment as set out in paragraphs 64 (a) or (b) of CEPA 1999, but that it is harmful to human health as set out in paragraph 64 (c) of CEPA 1999.

Risk management scope documents for DBDPE, DP and TCPP were also released in conjunction with the publication of these draft screening assessments, draft state of the science reports, and the risk management scope documents.

There was a 60-day public comment period associated with the publication of these draft screening assessments and draft state of the science reports.

Given the concerns related to the potential future increased use of TDCPP, follow-up activities will be considered to inform prioritization and evaluation of future new or increased use. The proposed path forward for tracking future changes in use pattern and/or environmental releases will be confirmed at the time of publication of the final screening assessment. This substance may be subject to further ecological and human health assessment, if warranted by new information.

Information Gathering

2017 Mandatory Survey - Section 71 Notice

In April 2017, a Notice was issued in the Canada Gazette, Part I: Vol. 151, No. 13 – April 1, 2017 (PDF Version 1,997 K) under section 71 of CEPA 1999. The Notice applies to approximately 31 substances that are toxic or proposed to be toxic as defined under section 64 of CEPA 1999. Two substances in this grouping, DP and DBDPE, (CAS RNs 13560-89-9 and 84852-53-9) are included in this Notice. More information, including how to submit a response is available on the Certain Substances Requiring Information for Risk Management webpage.

2013 Mandatory Survey - Section 71 Notice

In March 2013, a Notice was issued in the Canada Gazette, Part I: Vol.147, No.13 - March 30, 2013 (PDF Version - 1,156 K) under section 71 of CEPA 1999. This Notice applied to the ten substances included in the Certain Organic Flame Retardants Substance Grouping and sought to obtain information to inform the risk assessment and, if necessary, the risk management for this group of substances.
