Substituted Diphenylamine Substance Grouping

Help on accessing alternative formats, such as Portable Document Format (PDF), Microsoft Word and PowerPoint (PPT) files, can be obtained in the alternate format help section.

Certain substituted diphenylamine substances are among those identified as priorities for action for the second phase of the Chemicals Management Plan (CMP). The selection of these substituted diphenylamine substances for action is based on the categorization process completed in 2006, and new information received as part of the first phase of the CMP.

Section 71 Notice (Mandatory Survey)

In June, 2012, a Notice was issued in the  Canada Gazette, Part I: Vol.146, No.26 - June 30, 2012 ( PDF Version - 5248 K) under section 71 of the Canadian Environmental Protection Act, 1999 (CEPA 1999). This Notice applies to 13 substances which are part of the Substituted Diphenylamine Substance Grouping.

Every person to whom this Notice applies is required to comply with the Notice no later than 5 p.m. EDT, October 30, 2012. Please note that under subsection 71(4) of the Act, extensions may be granted upon written request. To apply for an extension, a written request must be submitted to the Minister of the Environment, to the attention of the Substances Management Coordinator, prior to the deadline. Please see the Guidance Document for completing the CEPA section 71 Notice.

Persons who do not meet the requirements to respond to this Notice and have no commercial interest in the substances listed in the Notice, may complete a Declaration of Non-Engagement form for the Notice. In addition, persons who do not meet the reporting requirements of the Notice, but who have a current or future interest in any of the substances listed in the Notice, are encouraged to identify themselves as a stakeholder for the substance by completing the voluntary Declaration of Stakeholder Interest form, and/or by completing the Notice voluntarily. Organizations that may be interested in submitting additional information include those that manufacture, import, export or use a substance, whether alone, in a mixture, in a product or in a manufactured item. In addition to information on types of uses and volumes imported, exported, manufactured and used, there is specific interest in unpublished data or studies which could help inform the risk assessment process. Information on industrial best waste management practices and environmental releases are also of interest. The Declaration of Stakeholder Interest form allows the person to provide other information that would be beneficial to inform the risk assessment and potential risk management of the substances. The person will be included in future mailings regarding these substances and may be contacted for further information regarding their interest in these substances.

The information collected from this section 71 Notice will inform the risk assessment and, if necessary, risk management for these substances. Information provided to Environment Canada and Health Canada under previous initiatives will also be taken into consideration.

Respondents are encouraged to submit their section 71 Notice and Declaration of Non-Engagement form online. The Declaration of Stakeholder Interest form may be submitted via e-mail, mail or fax. The Chemicals Management Plan (CMP) eSubmissions online system is available via  Environment Canada's Single Window for reporting. Respondents are required to register for a Government of Canada Access Key to access this new system and can do so by clicking "Register" on the initial screen.

Timelines

Date	Activity
June 30, 2012	Release of the section 71 Notice with respect to certain substituted diphenylamine substances and the accompanying technical documents.
October 30, 2012	Deadline for submission of information for the section 71 Notice (without an extension).
December 31, 2012	Deadline for submission of any voluntary information by interested stakeholders.
Winter 2013/2014	Anticipated release of the draft screening assessment in Canada Gazette and start of 60-day public comment period.

Path Forward

To identify data gaps in the assessment of these substances, the Government of Canada has conducted literature searches and identified studies on parameters such as physical-chemical properties, ecological toxicity, and human health effect endpoints, which are available in the public domain for each substance.

The Government of Canada will apply weight of evidence and precaution in decision-making. Accordingly, where data is limited, the Government of Canada will apply conservative assumptions in the risk assessment for factors such as:

• the potential for these substances to degrade or metabolize;
• the potential for these substances to migrate or leach from finished products;
• the potential for dermal uptake from products in contact with the skin;
• the potential for these substances to cause health effects or degrade or metabolize to substances which may cause health effects;
• the potential for these substances to cause harm to biota in the environment; and
• the potential for these substances to bioaccumulate.

Draft screening assessments for the substances in the Substituted Diphenylamine Substance Grouping will be released, and there will be a 60-day public comment period for each release.

Background

In October 2011, an announcement was published in the  Canada Gazette, Part I: Vol. 145, No. 41- October 8, 2011 regarding planned actions to assess and manage, where appropriate, the risk posed by certain substances to the health of Canadians and the environment. This initiative builds on the first phase of the Chemicals Management Plan (CMP) by identifying approximately 500 substances, in nine substance groupings, as priorities for the second phase of the CMP. These substances will be assessed over the coming five years.
