Diversion and Dewatering of Luce Lake North, Labrador West

Proponent: Iron Ore Company of Canada (IOC)

Summary of Environmental Assessment Process

Project Description:

The proponent has submitted a proposal to dewater and divert inflows away from Luce Lake North, directly adjacent to Luce Pit, at its Labrador West mine site. This work will be accomplished by constructing three diversion channels, a low dam and by pumping down the lake. IOC considers that complete dewatering and diversion of inflows away from Luce Lake North is the best option to improve Luce Pit dewatering, minimize potential effects on downstream aquatic habitat, and to minimize safety and operational risks for continued mining in Luce Pit. The project will also involve the relocation of fish from Luce Lake North, measures to offset serious harm to fish and fish habitat as a result of project activities, relocation of groundwater discharges from Luce Pit, controlled dewatering of Luce Lake North and the installation and maintenance of a sump pump system in the Luce Lake North basin to manage groundwater infiltration, surface water inflows and snowmelt runoff.
