Substance Groupings Initiative

The following substances in this batch have been included in the Aromatic Azo and Benzidine-based Substance Grouping under Substance Groupings Initiative as part of the second phase of the Chemicals Management Plan. As outlined in the notice of intent for the Aromatic Azo and Benzidine-based Substance Grouping, it was recognized that assessments and conclusions pertaining to some of the substances in the grouping may be subsequently updated as part of the subgroup assessment. The latest updates on these substances are found on the respective Substance Groupings Initiative pages.

Risk management action milestones

The risk management action milestones table outlines the risk management actions that were proposed for each chemical substance in this batch of the Challenge that met the criteria of section 64 of the Canadian Environmental Protection Act, 1999 (CEPA 1999). These proposed risk management actions were published in the risk management approaches for these substances. For the complete wording of these proposed actions, please refer to the risk management approaches.

Adding substances to Schedule 1

Two substances in this batch have been included in final orders to add to Schedule 1.

• Final order adding acrylamide (CAS RN 79-06-1) and TCEP (CAS RN 115-96-8): Canada Gazette, Part II: Vol. 145, No. 5 - March 2, 2011

Applying Significant New Activity provisions

View the Significant New Activity Publications under the Canadian Environmental Protection Act, 1999. Orders are subject to potential amendments under the Significant New Activity (SNAc) Review.

• Order amending the Domestic Substances List (DSL) that applies to TCEP (CAS RN 115-96-8): Canada Gazette, Part II: Vol. 147, No. 3 - January 30, 2017
• Order amending the DSL that applies to chloroacetamide (CAS RN 79-07-2): Canada Gazette, Part II: Vol. 144, No. 23 - November 10, 2010
• Order amending the DSL that applies to Disperse Orange 5 (CAS RN 6232-56-0): Canada Gazette, Part II: Vol. 143, No. 19 - September 16, 2009

For additional guidance on submitting information required as part of SNAc requirements, please see the Guidelines for the Notification and Testing of New Substances: Chemicals and Polymers.

Varying the requirements under the Significant New Activity provisions

In February 2022, a notice of intent to amend the DSL to vary the requirements under the SNAc provisions for 2-chloroacetamide (CAS RN 79-07-2) was published in the Canada Gazette, Part I: Vol. 156, No. 6 – February 5, 2022 for a 60-day public comment period. The proposed amendments are an outcome of the SNAc Review. The DSL amendments do not come into force until the final order is published in the Canada Gazette, Part II. Any current requirements under the SNAc provisions remain in effect until then.

In January 2017, a notice of intent to amend the DSL to vary the requirements under the SNAc provisions for TCEP (CAS RN 115-96-8) was published in the Canada Gazette, Part I: Vol. 151, No. 2 - January 14, 2017. The proposed amendments are an outcome of the SNAc Review. The DSL amendments do not come into force until the final order is published in the Canada Gazette, Part II. Any current requirements under the SNAc provisions remain in effect until then.

Rescinding requirements under the Significant New Activity provisions

In July 2017, the requirements under the SNAc provisions for Disperse Orange 5 (CAS RN 6232-56-0) were rescinded. This substance was subject to the SNAc provisions as a result of the 2009 assessment of substances in this batch. It was later included in the Certain Azo Disperse Dyes subgroup, and the March 2017 assessment of that subgroup concluded that this substance is no longer of concern to the environment. An order was published in the Canada Gazette, Part II: Vol. 151, No. 14 - July 12, 2017 rescinding the requirements under the SNAc provisions of CEPA 1999 for this substance.

Summary of Batch 5 substances and publications

Final screening assessments and risk management approaches

In August 2009, the final screening assessments for this batch were released and the related notices were published in the Canada Gazette, Part I: Vol. 143, No. 34 - August 22, 2009.

The final screening assessments concluded that 2 substances in this batch meet 1 or more criteria in section 64 of CEPA 1999. The Government added these substances to Schedule 1 of the Act. Proposed risk management approaches were also released on this date for the substances in this batch which met the criteria in section 64 of CEPA 1999.

Draft screening assessments and risk management scopes

New information was received from industry or interested stakeholders for each of the 19 substances in this batch. In February 2009, the draft screening assessments were released and the related notices were published in the Canada Gazette, Part I: Vol. 143, No. 8 - February 21, 2009. Risk management scopes were also released in conjunction with these publications.
