Chemical substances in Batch 8 of the Challenge

Mandatory survey - section 71 notice

In addition to the Batch 8 section 71 survey notice issued in 2009, in April 2017, a notice was issued in the Canada Gazette, Part I: Vol. 151, No. 13 – April 1, 2017 under section 71 of the Canadian Environmental Protection Act, 1999 (CEPA 1999). The notice applies to 50 substances that are toxic as defined under section 64 of CEPA 1999. One substance in this Batch, DTBSBP (CAS RN 17540-75-9), is included in this notice. More information, including how to submit a response, is available on the Certain substances requiring information for risk management webpage.

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 1999. These proposed risk management actions were published in the risk management approach documents for these substances. For the complete wording of these proposed actions, please refer to the risk management approach documents.

Adding substances to Schedule 1

Four substances in this batch have been included in a final order to add to Schedule 1.

Applying Significant New Activity provisions

View the Significant New Activity Publications under the Canadian Environmental Protection Act, 1999.

Eight substances in this batch were to be addressed through the application of the Significant New Activity (SNAc) provisions. Three orders have been published addressing 7 substances in this batch through the application of the SNAc provisions.

However, for the remaining substance PADMEC (CAS RN 65140-91-2), considering the low reported and potential industrial activities and expected minimal presence of the substance in the environment, risks to the general population are considered to be low. Therefore, further to the notice of intent published for this substance in January 2010, an order amending the Domestic Substances List (DSL) for PADMEC will not be published. This decision is consistent with the Policy on the use of SNAc provisions of CEPA 1999, published in December 2013.

In January 2017, a notice of intent to amend the DSL to vary the SNAc requirements for 2-Nitropropane (CAS RN 79-46-9), DTBSBP (CAS RN 17540-75-9), and MAPBAP acetate (CAS RN 72102-55-7) was published in the Canada Gazette, Part I. The proposed amendments are an outcome of the SNAc Review. The amendments are not in force until the final order is adopted by the Minister of Environment and Climate Change pursuant to subsection 87(3) of CEPA 1999. The final order will be published in the Canada Gazette, Part II. Any current SNAc requirements remain in effect until such time as the final order is published.

Rescinding Significant New Activity provisions

In January 2017, a notice of intent to amend the DSL to rescind the SNAc requirements for FAZ (CAS RN 68551-44-0) was published in the Canada Gazette, Part I. The proposed rescission is an outcome of the SNAc Review. Potential for environmental persistence, bioaccumulation, and toxicity were identified in the screening assessment, but little data on the substance was available at the time. In 2013, an analogous substance was assessed by Environment Canada, and it was found not to meet the criteria for persistence or bioaccumulation potential. Also, recent industry surveys revealed that commercial activity for the analogous substance is low, and therefore the likelihood for exposure to humans or the environment is also low. Therefore, the SNAc requirements are proposed to be rescinded for FAZ. Current SNAc requirements remain in effect until such time as a final order is published in the Canada Gazette, Part II.

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.

Final screening assessments and risk management approaches

In September 2011, the final screening assessment for the remaining substance in this batch was released in the Canada Gazette, Part I: Vol. 145, No. 37 - September 10, 2011.

In July 2010, the final screening assessments for 13 of the 14 substances in this batch were released in the Canada Gazette, Part I: Vol. 144, No. 31 - July 31, 2010.

The final screening assessments concluded that 4 substances in this batch meet one or more criteria in section 64 of CEPA 1999. The Government proposed to add these substances to Schedule 1 of the act. Proposed risk management approach documents were also released on this date for the substance in this batch which met the criteria in section 64 of CEPA 1999.

In addition, a Consultation Document on the Proposed Risk Management for DTBSBP was published in December 2011 which outlines the change in proposed risk management for DTBSBP.

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 January 2010, the draft screening assessments were released and the related notices were published in the Canada Gazette, Part I: Vol. 144, No. 5 - January 30, 2010. Risk management scope documents were also released in conjunction with these publications.

New information was received during the public comment period for the initial screening assessment for 1 substance (PADMEC) in this batch. Therefore, it was decided to conduct further assessment work on this substance to take this new information into consideration, and to release a revised draft screening assessment. The conclusion of the revised draft screening assessment is that this substance does not meet any of the criteria in section 64 of CEPA 1999. A notice relating to the release of the draft screening assessment report was published in October 2010 in the Canada Gazette, Part I: Vol. 144, No. 40 - October 2, 2010.

Launch of Batch 8 and submissions received

Information on substances in this batch was gathered from industry and interested stakeholders through a mandatory survey notice issued under section 71 of CEPA 1999. They were also invited to complete a voluntary questionnaire.

A notice related to the launch of Batch 8 was published in January 2009 in the Canada Gazette. The section 71 notice applied to all 14 substances in this batch.
