Reasons for a Federal Assessment

On June 25, 2008, it was determined that an environmental assessment was required in relation to the project because Fisheries and Oceans Canada considered taking action in relation to subsection 35(2) of the Fisheries Act; Natural Resources Canada considered providing federal lands; the Prince Rupert Port Authority considered providing federal lands and Transport Canada considered taking action in relation to section 5 of the Navigable Waters Protection Act.

Project Description (as posted in the Notice of Commencement)

Naikun Wind Development Corporation (the Proponent) proposes to develop (construction, operation and decommissioning) a wind energy generating facility (Naikun Wind Generation Facility), in the shallow waters off the northeast coast of Haida Gwaii in Hecate Strait, BC. The Proponent proposes to install 67-110 turbines, spaced 450-1000m apart with an anticipated capacity of 320 megawatts, covering an area of 30-60 square kilometers. The hub of each turbine is at an approximate elevation of 80 meters above the ocean surface and is mounted to a tower that is anchored to the seabed. The lower extremity of the blades is no less than 20m above the water at highest astronomical tide. Each tower will have a diameter of 6m. The generated power from the turbines will be gathered via sea cables at an offshore substation and transmitted via buried underwater sea cables westward to Haida Gwaii (through a 69kV cable with a landfall near Tlell) and eastward to the BC mainland where it will connect with BC Hydro's substation near Port Edward via a 287-kV transmission line.

Final Decision

A decision was taken on March 16, 2011 and was that the authorities may exercise any power or perform any duty or function with respect to the project because, after taking into consideration the screening report and taking into account the implementation of appropriate mitigation measures, the authorities are of the opinion that the project is not likely to cause significant adverse environmental effects.

Follow-up Program

It was determined that a follow-up program to verify the accuracy of the environmental assessment and/or determine the effectiveness of any measures taken to mitigate the adverse environmental effects is required for this project.
