CMP: Draft Batch 7 Results Released

This past Saturday, the Canadian government released the draft screening assessment reports for 14 substances assessed in Batch 7 of the Chemicals Management Plan. The government is considering classifying three of the 14 substances as CEPA-toxic (on the basis of human health concerns). These three substances are: (a) Michler's ketone (imported into Canada and used in dry film products, inks, pens, and electronics manufacturing); (b) n-BGE (a diluent for epoxy resins used in chemical manufacturing); and (c) 2-butanone oxime (anti-skinning agent in paints, varnishes, etc.). Of the 11 remaining substances, the government is proposing to make five subject to the SNAc provisions of CEPA: Pigment Yellow 60, Solvent Yellow 18, Solvent Blue 5, Solvent Blue 4, and Pigment Brown 22. Currently none of these substances are manufactured in or imported into Canada in a quantity above 100 kg in a calendar year, but should that change, a risk assessment would be required. The public comment period on the draft screening assessments runs until November 4, 2009. The draft risk assessments (and three risk management scope documents) can be found here.
