Section 71 Survey Notice
The following Notice, issued under section 71 of the Canadian Environmental Protection Act, 1999, entitled: Notice with respect to certain Batch 2 Challenge substances applies to 15 of the 17 substances in the second group identified under the Challenge. A previous Notice requiring information included two of the 17 substances (CAS No. 732-26-3 and 15086-94-9) and provided sufficient information not to warrant their inclusion in the current Notice.
Every person to whom the Notice applies must comply with the Notice by no later than 3:00 p.m. EDT, September 12, 2007. Please note that under subsection 71(4) of the Act, extensions for a maximum of two months may be granted in some cases upon written request. To apply for an extension, a written request and justification must be received by the Minister of the Environment prior to the deadline.
Questionnaire
In addition, Industry and interested stakeholders are also invited to submit, within six months (on or before November 13th, 2007), further information regarding the scientific properties of these substances, or best management practices associated with the use of these substances that might contribute to improved decision-making. Information on the type of information that could be submitted, and logistics for submitting information is detailed in the Challenge Questionnaire and related Guidance Document below.

Information Workshops for Stakeholders
Environment Canada and Health Canada hosted workshops in Toronto on June 7, 2007 and in Calgary on June 12, 2007, to help further explain to stakeholders the Challenge, the associated documentation and how to participate. It should be emphasized that the objectives of the workshop were for federal officials to provide details on what information is being sought for the Challenge, how participants are to submit this information, and the associated timelines. Discussion focused on the documents associated with the Challenge which are provided on this website.
Environment Canada and Health Canada will consider hosting similar information workshops for stakeholders in late September or early October 2007, following the launch of Batch 3 of the Challenge, should the number of requests received from interested stakeholders warrant this. To express interest in attending an Information Workshop for Batch 3, please contact, by August 31, 2007, Obah_Omer@hc-sc.gc.ca
