Traduction de «Storage pond » (Anglais → Français) :

This is a 20-acre facility, with about 20 ponds for treatment and two extra ponds for storage.

In Units 3 and 4, decommissioning measures are only possible to a limited extent, as the storage ponds still contain irradiated fuel elements.

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 governmen ...[+++]t 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 ...

In addition, the difficulty in managing the transport, storage and use of cyanide, combined with shortcomings in operating and maintaining tailing ponds, not to mention bad weather, can result in explosive situations, with a devastating impact on the environment.

In practice, in order to meet the strict limit values, it is necessary to install specific equipment destroying most of the cyanide before its storage in the pond.

We were encouraging surface storage and bypass ponds.
