The wastewater treatment sludge generated by automotive manufacturers has been delisted as a hazardous material in Ontario.
In a post to Ontario’s Environmental Bill of Rights Registry (EBR), the Ontario Ministry of the Environment states that Regulation 347 (General – Waste Management) under the Environmental Protection Act has been amended to reflect the change.
According to the EBR, “The Canadian Vehicle Manufacturers Association (CVMA) and Ontario’s automobile manufacturers requested this amendment to reflect changes made to the vehicle manufacturing process that have removed contaminants of concern which has resulted in the waste sludge no longer exhibiting any hazardous waste characteristics and is therefore a non-hazardous waste.”
The Ontario Ministry of the Environment said it’s important to note that automotive manufacturers are still responsible for properly characterizing and managing the sludge as required by Regulation 347. Waste disposal sites must be approved to accept this waste.
The Ministry said the amendment is intended as a disincentive to using more aluminum in the manufacturing of vehicles, producing lighter vehicles with better gas mileage and decreasing exhaust and greenhouse gas emissions.
As well, it is in line with the US EPA’s delisting of this waste stream which helps maintain the competitiveness of Ontario’s automotive manufacturers.
Ontario Regulation 233/13 amending Reg. 347 of R.R.O. 1990 (General – Waste Management) made under the Environmental Protection Act, came into force upon filing on August 15, 2013.
