Adding Substances to Schedule 1 of the Canadian Environmental Protection Act
Perfluorooctanoic acid (PFOA), its salts and its precursors were determined to meet one or more of the criteria in section 64 of the Canadian Environmental Protection Act, 1999 (CEPA 1999) and therefore were proposed to be added to Schedule 1.
- Proposed Order adding PFOA, its salts and its precursors:
Canada Gazette, Part I, Vol. 146, No. 39 – September 29, 2012 ( PDF Version - 904 K).
Final Screening Assessment and Proposed Risk Management Approach
In August 2012, the Final Screening Assessment Report on Perfluorooctanoic Acid (PFOA), its Salts and its Precursors was released and the related Notice was published in the Canada Gazette, Part I: Vol. 146 No. 34 - August 25, 2012 ( PDF Version - 1095 K).
The final ecological screening assessment concluded that PFOA, its salts and its precursors meet one or more of the criteria in section 64 of the Canadian Environmental Protection Act, 1999 (CEPA 1999). Additionally, it is concluded that PFOA and its salts meets the criteria for persistence but does not meet the criteria for bioaccumulation potential set out in the Persistence and Bioaccumulation Regulations. Nevertheless, the weight of evidence is sufficient to conclude that PFOA and its salts accumulate and biomagnify in terrestrial and marine mammals.
A Proposed Risk Management Approach on Perfluorooctanoic Acid (PFOA), Its Salts, and Its Precursors was also released on August 25, 2012 for a 60-day public comment period.
Information on how to submit comments is provided in the Canada Gazette Notice.
Draft Screening Assessment and Risk Management Scope
In October, 2010, the draft Screening Assessment Report on perfluorooctanoic acid (PFOA), its salts and its precursors was released and the related Notice was published in the Canada Gazette, Part I: Vol. 144, No. 44 - Octobre 30, 2011 ( PDF Version - 1,091 K). A risk management scope document was also released in conjunction with this publication.
The draft screening assessment of one of the PFOA salts (CAS No. 3825-26-1), and four potential PFOA precursor substances (CAS Nos. 678-39-7, 53515-73-4, 65530-61-2 and 70969-47-0), was conducted under sections 68 and 74 of the Canadian Environmental Protection Act, 1999 (CEPA 1999) because they were found to meet the ecological categorization criteria for persistence and/or bioaccumulation potential and inherent toxicity to non-human organisms.
The draft screening assessment of PFOA and the other PFOA salts and potential precursor substances was conducted under section 68 of CEPA 1999, because they were not found to meet the categorization criteria, or they were not categorized since they do not appear on the Domestic Substances List (DSL).
The draft screening assessment report proposes to conclude that PFOA, its salts and its precursors meet one or more of the criteria set out in section 64 of CEPA 1999.
The public comments received were considered and addressed within the final screening assessment report, and a Summary Table of Public Comments Received on the Draft Screening Assessment Report on Perfluorooctanoic Acid (PFOA), Its Salts and Its Precursors is available.
