Hexabromocyclododecane (HBCD)

Risk management action milestones

In December 2018, Environment and Climate Change Canada and Health Canada published the Consultation Document on Proposed Amendments to the Prohibition of Certain Toxic Substances Regulations, 2012 for PFOS, PFOA, LC-PFCAs, HBCD, PBDEs, DP and DBDPE.

The objective of this consultation document is to inform stakeholders of the proposed amendments to the Prohibition of Certain Toxic Substances Regulations, 2012, solicit comments and request information. Comments and information are requested by February 18, 2019.

Comments and information received in response to the consultation document will be considered in the development of the proposed Regulations to Amend the Prohibition of Certain Toxic Substances Regulations, 2012.

In October 2018, a notice of intent was issued in the Canada Gazette, Part I: Vol. 152, No. 41 – October 13, 2018  indicating that the Department of the Environment and the Department of Health were initiating the development of amendments to the Prohibition of Certain Toxic Substances Regulations, 2012. These amendments would seek to further restrict the manufacture, use, sale, offer for sale and import of certain toxic substances, including HBCD. There was a 30-day consultation period associated with this publication. Comments received on this publication will be considered in the development of the proposed Regulations to Amend the Prohibition of Certain Toxic Substances Regulations, 2012.

In October 2016, the Regulations Amending the Prohibition of Certain Toxic Substances Regulations, 2012 were published in the Canada Gazette, Part II: Vol. 150, No. 20 - October 5, 2016 and came into force in December 2016. These amendments include controls on HBCD that prohibit HBCD and certain products containing the substance.

In April 2015, the proposed Regulations Amending the Prohibition of Certain Toxic Substances Regulations, 2012 were published in the Canada Gazette, Part I: Vol. 149, No. 14 - April 4, 2015, for a 75-day public comment period. Comments received during this period were considered in the final development of these regulations. Comments and the Government's response are provided in the summary of public comments received on the proposed Regulations Amending the Prohibition of Certain Toxic Substances Regulations, 2012.

In October 2012, a Consultation Document on the Proposed Risk Management Measure for Hexabromocyclododecane (HBCD) was published. Comments and the Government's response are provided in the summary of public comments received on the consultation document on the proposed risk management measure for HBCD. Comments received were considered during the development of the proposed risk management action.

Adding substances to Schedule 1

HBCD was determined to meet one or more of the criteria in section 64 of the Canadian Environmental Protection Act, 1999 (CEPA 1999) and has therefore been included in a final order to add to Schedule 1.

Final screening assessment and proposed risk management approach

In November 2011, the Final Screening Assessment on Hexabromocyclododecane was released and the related notice was published in the Canada Gazette, Part I, Vol. 145, No. 46 - November 12, 2011.

The final screening assessment concluded that HBCD meets one or more of the criteria set out in section 64 of the CEPA 1999. Additionally, HBCD meets the criteria for persistence and bioaccumulation potential as set out in the Persistence and Bioaccumulation Regulations.

A proposed Risk Management Approach on Hexabromocyclododecane (HBCD) was also released on this date for a 60-day public comment period.

Draft screening assessment and risk management scope

In August 2010, the Draft Screening Assessment on HBCD was released and the related notice was published in the Canada Gazette, Part I: Vol. 144 No. 35 - August 28, 2010 for a 60 day public comment period. A risk management scope was also released on this date.

The public comments received were considered and addressed within the final screening assessment, and are provided in the summary of public comments received on the risk management scope and draft screening assessment for HBCD.

Background

Before the launch of the Chemicals Management Plan in 2006, HBCD was selected for a screening assessment. Subsequently, under the categorization exercise, HBCD was identified as a high priority for screening assessment, as it met the criteria for persistence, bioaccumulation and inherent toxicity to aquatic life.
