Substance Groupings Initiative
The following substance in this batch has 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 web 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 CEPA. 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
Four substances in this batch have been added to Schedule 1 to CEPA.

In March 2026, an order amending the DSL to vary the requirements under the SNAc provisions of CEPA for five substances in this batch (CAS RNs 38465-55-3, 475-71-8, 1326-05-2, 14295-43-3 and 58161-93-6) was published in the Canada Gazette, Part II: Vol. 160, No. 6 – March 25, 2026. The amendments are an outcome of the SNAc Review.
In January 2017, a notice of intent to amend the DSL to vary the requirements under the SNAc provisions of CEPA for methyl eugenol (CAS RN 93-15-2), TGOPE (CAS RN 7328-97-4), potassium bromate (CAS RN 7758-01-2) and vanadium pentoxide (CAS RN 1314-62-1) was published in the Canada Gazette, Part I: Vol. 151, No. 2 - January 14, 2017 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.
Final screening assessments and risk management approaches
In September 2010, the final screening assessments for substances in this batch were released and the related notices were published in the Canada Gazette, Part I: Vol. 144, No. 38 - September 18, 2010.
The final screening assessments concluded that four substances in this batch meet one or more criteria in section 64 of CEPA. The Government added these substances to Schedule 1 to CEPA. 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.
Draft screening assessments and risk management scopes
New information was received from industry or interested stakeholders for each of the 17 substances in this batch. In March 2010, the draft screening assessments were released and the related notices were published in the Canada Gazette, Part I: Vol. 144, No. 12 - March 20, 2010. Risk management scopes were also released in conjunction with these publications.
Information gathering
