Consultation on proposed new risk management actions

In July 2022, the Consultation Document on Proposed New Risk Management Actions for 2-Butanone, oxime was published for a public comment period, ending on October 13, 2022. The purpose of this document is to consult interested stakeholders on proposed new risk management actions for 2-butanone, oxime (butanone oxime CAS RN 96-29-7) used in certain products available to consumers, particularly, paints and coatings; stains and finishes; and adhesives and sealants. Additional information is available on the Health-related consultations web page.

This consultation is taking place as a result of the performance measurement evaluation, published in July 2020. The evaluation concluded that the risk management actions taken have not achieved their objective. As such, new risk management actions for butanone oxime are proposed.

Information gathering

Section 71 Chemicals Management Plan 2023

In June 2023, a notice was published in the Canada Gazette, Part I: Vol. 157, No. 25 – June 24, 2023 under section 71 of the Canadian Environmental Protection Act, 1999 (CEPA 1999). This notice applies to 1 substance in this batch, 2-butanone, oxime (CAS RN 96-29-7). More information is available on the Information gathering with respect to certain substances under the Chemicals Management Plan web page.

2019 Voluntary information gathering

In May 2019, a voluntary information gathering questionnaire was distributed to certain stakeholders regarding 1 substance in this batch, 2-butanone, oxime (CAS RN 96-29-7). Information received through this questionnaire is being gathered to evaluate risk management measures established under the Code of Practice for 2-Butanone, oxime (Butanone oxime) Associated with the Interior Application of Consumer Alkyd Paint and Coating Products. The questionnaire applied to those who, during the 2018 calendar year, manufactured, imported or sold interior or dual use (interior/exterior) consumer alkyd paint and coating products containing Butanone oxime or were responsible for ensuring their compliance with Canadian labelling requirements.

2008 Mandatory survey - section 71 notice

In August 2008, a notice was issued in Canada Gazette, Part I: Vol.142, No.35 - August 30, 2008 under section 71 of CEPA 1999. This notice applied to all 14 substances in this batch.

Substance Groupings Initiative

The following substances in this batch have been included in the Aromatic Azo and Benzidine-based Substance Grouping under the Substance Groupings Initiative as part of the second phase of the CMP. 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 the chemical substances in this batch of the Challenge that met the criteria of section 64 of 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.

Performance measurement

Conducting performance measurement evaluations allows the Government to assess whether the risk management actions taken on substances found to be toxic under CEPA 1999 were effective in meeting risk management objectives, or whether adjustments would help to protect Canadians and their environment. Performance measurement evaluation reports for substances in this batch with risk management actions will be published as they become available.

Adding substances to Schedule 1

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

• Final order adding Michler's ketone (CAS RN 90-94-8), butanone oxime (CAS RN 96-29-7) and n-BGE (CAS RN 2426-08-6): Canada Gazette, Part II: Vol. 145, No. 26 - December 21, 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 Michler's ketone (CAS RN 90-94-8) and n-BGE (CAS RN 2426-08-6): Canada Gazette, Part II: Vol. 147, No. 18 - August 28, 2013
• Order amending the DSL that applies to 5 substances (CAS RNs 1325-86-6, 6407-74-5, 6407-78-9, 6786-83-0 and 29398-96-7): Canada Gazette, Part II: Vol. 144, No. 7 - March 31, 2010

For additional guidance on submitting information required as part of SNAc notifications, 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 July 2019, a notice of intent to amend the DSL to vary the requirements under the SNAc provisions for Solvent Blue 5 (CAS RN 1325-86-6) was published in the Canada Gazette, Part I: Vol. 153, No. 30 - July 27, 2019 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 SNAc requirements for Michler's ketone (CAS RN 90-94-8) and n-BGE (CAS RN 2426-08-6) 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.

Rescinding the requirements under the Significant New Activity provisions

In October 2016, the requirements under the SNAc provisions for Solvent Yellow 18 (CAS RN 6407-78-9) and Pigment Yellow 60 (CAS RN 6407-74-5) were rescinded. Solvent Yellow 18 and Pigment Yellow 60 were subject to the SNAc provisions as a result of the 2010 screening assessment of substances in this batch. Solvent Yellow 18 was later included in the Certain Azo Solvent Dyes Subgroup, and Pigment Yellow 60 was included in the Certain Monoazo Pigments Subgroup. The 2016 assessment of those subgroups concluded that Solvent Yellow 18 and Pigment Yellow 60 do not pose a risk to the environment or human health. Therefore, an order amending the DSL to rescind the requirements under the SNAc provisions for these substances was published in the Canada Gazette, Part II: Vol. 150, No. 21 - October 19, 2016.

Summary of Batch 7 substances and publications

Final screening assessments and risk management approaches

In March 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. 10 - March 6, 2010.

The final screening assessments concluded that 3 substances in this batch meet one or more criteria in section 64 of CEPA 1999. The Government added these substances to Schedule 1 to 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 14 substances in this batch. In September 2009, the draft screening assessments were released and the related notices were published in the Canada Gazette, Part I: Vol. 143, No. 36 - September 5, 2009. Risk management scopes were also released in conjunction with these publications.
