Proposed Order to Add Chlorinated Naphthalenes to Schedule 1 to the Canadian Environmental Protection Act, 1999

(Public comment period August 6, 2011 to October 5, 2011)

On August 6, 2011, a proposed Order adding toxic substances to Schedule 1 to the Canadian Environmental Protection Act, 1999 (CEPA 1999) was published in the Canada Gazette, Part I, for chlorinated naphthalenes (CAS No. 70776-03-3) that were determined to meet the criteria in section 64 of the Act.

Final Ecological Screening Assessment Report and Proposed Risk Management Approach Document

On July 2, 2011, the results of a final ecological screening assessment report was published in Part I of the Canada Gazette on chlorinated naphthalenes (CAS¹ No. 70776-03-3). A summary of the final ecological screening assessment report on chlorinated naphthalenes is available:

•   Canada Gazette, Part I: Vol. 145, No. 27 - July 2, 2011 ( PDF Version - 2280 K)

Based on the information available, it is concluded that polychlorinated naphthalenes meet one or more of the criteria set out in section 64 of the Canadian Environmental Protection Act, 1999 (CEPA 1999). They are persistent and bioaccumulative in accordance with the Persistence and Bioaccumulation Regulations, their presence in the environment results primarily from human activity, and they are not a naturally occurring radionuclide or a naturally occurring inorganic substance, therefore they meet the criteria set out in subsection 77(4) of CEPA. As such, risk management measures are being proposed to achieve the ultimate environmental objective of virtually eliminating releases of polychlorinated naphthalenes.

The full text of the final ecological screening assessment report is available:

A proposed risk management approach document was also released on July 2, 2011, for chlorinated naphthalenes meeting the criteria in section 64 of CEPA 1999. This proposed risk management approach document builds on the previously released risk management scope document, and outlines, in more depth, the risk management actions for these substances, including the choice of instruments. There is a 60-day public comment period on this proposed risk management approach document, from July 2, 2011, to August 31, 2011.

Background

Draft Ecological Screening Assessment Report and Risk Management Scope Document

On July 18, 2009, the results of a draft ecological screening assessment report on chlorinated naphthalenes were published in the Canada Gazette, Part I, Vol. 143 No. 29. In addition, the risk management scope document (preliminary outlines of the options being examined for the management of substances, based on the proposed conclusions of the draft screening assessments) was released.

There was a 60-day public comment period associated with these publications. Public comments were submitted on (a) the draft screening assessments, (b) the proposal to pursue one of the measures as specified under subsection 77(2) the Canadian Environmental Protection Act, 1999 (CEPA 1999), and (c) the risk management scope documents. Public comments were considered and addressed within the final report, and responses to the comments are provided in the following table.
