Perhaps you can at some point in your leisure look at paragraph 132, which points out that 15 or 14 years ago a study found that the tailings from the Port Radium uranium and radium site were leaking radioactive materials into Great Bear Lake at a level exceeding Environment Canada's drinking water standards and that the water off the mine site contained radioactive materials exceeding Environment Canada's drinking guidelines.

Mines are heavily regulated at the provincial level, with permits required for all aspects, including road construction, water use and release, tailings and waste rock management and disposal, and reclamation.

Question No. 140 Ms. Kirsty Duncan: With respect to development of the oil sands, its impacts on the environment and surrounding communities, and the economic effects of these impacts: (a) what, if any, steps has the government taken to establish air emission limits or air quality standards to achieve the World Health Organization’s Air Quality Guidelines to protect air quality and human health; (b) what, if any, steps has the government’s sector-by-sector approach taken to regulate carbon emissions in the oil sands to ensure the oil sands industry makes appropriate reductions in its greenhouse gas (GHG) emissions to contribute to Canada’s GHG emission reduction goal of 17% below the 2005 level ...[+++]; (c) what, if any, studies has the government undertaken to examine the effect of the oil sands expansion on (i) GHG emissions, (ii) Canada’s ability to meet its GHG emission reduction goals, (iii) Canada’s contribution to the goal of staying below a 2°C increase in global average surface temperature, relative to the pre-industrial level, as articulated at the G8 meeting in L’Aquila, Italy and at the United Nations Framework Convention on Climate Change negotiations through the Copenhagen Accord in December 2009 and the Cancun Agreements in December 2010, (iv) the full suite of sustainability criteria, including environmental, economic and social sustainability, and (v) what were the results of any studies identified in (c)(i), (c)(ii), (c)(iii), and (c)(iv); (d) what, if any, studies has the government undertaken to examine (i) the scope of oil sands expansion if the oil sands sector is not required to deliver its proportional share of GHG reductions, (ii) the impacts such a decision would have on other sectors’ allowable GHG emissions, (iii) whether other sectors of the Canadian economy would have to do more than their proportional share to reduce emissions, (iv) what were the results of any studies identified in (d)(i), (d)(ii), and (d)(iii); (e) what, if any, studies ...

For instance, some of our current research includes continuing the assessment of toxicity and potential effects of tailings pond waters, assessment of acidifying emissions from oil sands and their impact on lake ecosystems, and assessment of the impacts of changes in flow and water levels in the Peace-Athabasca delta.
