The Ontario government has closed its consultation on July 25 to its proposed revisions to the Mining Act.
The following proposed revision will be of interest to CDA members:
Mine Development and Closure (Ontario Regulation 240/00)
Ontario Regulation 240/00, including the Mine Rehabilitation Code came into force in June 2000. The Mine Rehabilitation Code requires that all persons engaged in the design, construction, maintenance and decommissioning of tailings dams and other containment structures give due regard to the procedures and requirements in the Dam Safety Guidelines published by the Canadian Dam Association.
The Mine Rehabilitation Code does not provide for updating to the most recent version of the Dam Safety Guidelines. This means the Dam Safety Guidelines that were in place in June 2000 are the ones that apply.
The proposal is to amend Ontario Regulation 240/00, Part 4, Subsection 36 (1), regarding Tailings Dams and Other Containment Structures, so that it will refer to the most recent version of the Dam Safety Guidelines and its related technical bulletins.
The link below will lead you to the complete set of revisions.
