ensures the long-term geotechnical stability of any dams or heaps rising above the pre-existing ground surface.

the waste facility is suitably located, taking into account in particular Community or national obligations relating to protected areas, and geological, hydrological, hydrogeological, seismic and geotechnical factors, and is designed so as to meet the necessary conditions for, in the short and long-term perspectives, preventing pollution of the soil, air, groundwater or surface water, taking into account especially Directives 76/464/EEC , 80/68/EEC and 2000/60/EC, and ensuring efficient collection of contaminated water and leachate as and when required under the permit, and reducing erosion caused by water or wind as far as it is technic ...[+++]ally possible and economically viable;

to ensure short and long-term safe disposal of the extractive waste, in particular by considering, during the design phase, management during the operation and after-closure of a waste facility and by choosing a design which prevents or at least minimises any long-term negative effects attributable to migration of airborne or aquatic pollutants from the waste facility, and to ensure the long-term geotechnical stability of any dams or heaps rising above the pre-existing ground surface .

Q-97 — Mr. Stoffer (Sackville Musquodoboit Valley Eastern Shore) — In regard to the Tulsequah Chief Mine project: (a) which of the seventy stream crossings, sixty-four culverts and seven bridges to be undertaken in association with the proposed project pose the highest risks to the spawning or rearing habitats of chinook, sockeye, coho, pink, chum salmon, and to the water quality in the area; (b) which of the proposed undertakings pose the greatest risk to other fish species in the area such as Dolly Varden char and whitefish, and cutthroat, bull and steelhead trout; (c) what are the estimated costs to pump back and treat the metals tailing seepage entering the Shazah wetland as a result of the project operations; (d) what are the concer ...[+++]ns of the Department of Fisheries and Oceans related to post-closure issues and road issues including fish passage at crossings, sediment release from the road, the status of roads post-closure, habitat displacement at causeways, and the geotechnical stability of the road; (e) does the government acknowledge and support requests from the community, fishermen associations, NGOs, and the State of Alaska for the project to be referred to the Pacific Salmon Commission for study and recommendations, and if not, why not; (f) will government approval for the project constitute a breach of the " safe passage" provision in the Pacific Salmon Treaty, and if not, why not; (g) what is the government's methodology for the calculation of reclamation bonding to limit taxpayer liability given the mine's remote location and acid mine drainage risks to critical fish habitat; and (h) why has the site never been reclaimed and acid drainage from the mine, identified by Environment Canada in 1995 as acutely toxic to fish, been allowed to continue to flow into the Tulsequah River?

They believed it was a geotechnical problem and they would hire someone to conduct a geotechnical study.
