CNF/MH/NCN I – EIS – PROJ DES #250a
Why has Manitoba Hydro/NCN not chosen to develop a comprehensive access management plan now — before problems arise? Estimates of winter usage of the RoWs — when species such as caribou are especially vulnerable — are crucial for conservation planning.

CNF/MH/NCN I – EIS – PROJ DES #252

Wuskwatim EIS Interrogatories – Cumulative Effects Assessment (CEA)
CNF/MH/NCN I – EIS – CEA #272

CNF/MH/NCN I – EIS – CEA #274
Would Manitoba Hydro/NCN and its consultants describe existing knowledge of the region’s species and their ecology as adequate for the prediction of the potential (long-term, complex) impacts of proposed projects like Wuskwatim?
CNF/MH/NCN I – EIS – CEA #275

CNF/MH/NCN I – EIS – CEA #286
Manitoba Hydro/NCN omitted a review of the Transmission Project’s Residual Effects despite the inevitable long-term ecological problems that can be associated with rights-of-way. Does Manitoba Hydro guarantee no residual effects? Will a transmission residual effects plan be done?

The CEA for the Wuskwatim project region does not fully address the fragmentation of river systems (loss of connectivity). Please provide this analysis.
CNF/MH/NCN I – EIS – CEA #288
It is understandable that the choice of Valued Ecosystem Components (VECs) prioritizes exploited species. However, these represent a tiny fraction of Boreal Forest biodiversity. Why weren’t more ecological indicator species added to the list of taxa chosen for monitoring? Please provide sources, references to support approach taken in the EIS..
CNF/MH/NCN I – EIS – CEA #289
Why did Manitoba Hydro/NCN not choose more umbrella, keystone and ecological indicator species as “valuable ecosystem components” in both the Wuskwatim Generation and Transmission project EISs?
