CMP: Batch 5 Decisions Released

On August 22, the Canadian government released its final decisions on the screening asssessments of the 19 substances in Batch 5 of the Chemicals Management Plan. Of the 19 substances, two were determined to be CEPA-toxic: 2-Propenamide (acrylamide) and tris(2-chloroethyl) phosphate or TCEP. Acrylamide is used in the manufacture of various polymers which in turn are used as binding, thickening or flocculating agents in a variety of consumer products including food packaging. TCEP is used as a plasticizer in polyurethanes, polyester resins, polyacrylates and other polymers, which in turn is used in furniture products, roofing products, upholstery and some electronic products.

Of the 17 substances that will NOT be added to the Toxic Substances List, the federal government determined that two should be made subject to the Significant New Activity (SNAc) provisions of CEPA: the dye Disperse Orange 5, and the material preservative 2-chloroacetamide. The federal government determined that neither substance was being manufactured or imported into Canada above 100 kg per calendar year. If this changes, these chemicals will be reassessed.

    As for the remaining Batches, is there an up-to-date, complete list of CEPA-toxic substances that are now restricted?

    If you go to the federal government's Chemical Substances portal (URL is below) and scroll down the right-hand column, you will find the subheading "The Challenge". Below that you will find all the public information on the substances being assessed in each Batch (past, present and future). It is up-to-date as the substances proceed through the CEPA Part V process. So for example, if you click on Batch 1 you will find not only the final risk assessments, but the proposed Risk Management Scope document, and the proposed order for adding the substances determined to be toxic to the Toxic Substances List. Because the Toxic Substances List is a schedule to a federal statute (CEPA), there is a statutory process that takes some time to complete (so there will be a period of some months between a final risk assessment that concludes a substance is CEPA-toxic, and that substance being formally added to the TSL).
