Amendments to Ontario’s Regulation 347 (General Waste Management) under the province’s Environmental Protection Act came into effect last on November 10. A highlight of the revisions is the adoption of the Toxicity Characteristic Leachate Procedure (CLP) as the required method for determining if a waste is hazardous. Ontario is the second province after Alberta to adopt the procedure, which tests for 88 contaminants (comparatively, the US TCLP tests for 40). Other amendments add 129 new chemicals and industrial processes as well as a new “derived from” rule. This states that any waste classified as hazardous retains this classification until it can be clearly shown not to be hazardous. Clarification provisions have been added to provide a better understanding of these new rules.
