This project was assessed pursuant to an agreement to delegate the federal environmental assessment of the Project to the Government of British Columbia.
Responsible or Regulated Authorities
Fisheries and Oceans Canada
Reasons for a Federal Assessment
On December 2, 2009, it was determined that an environmental assessment was required in relation to the project because Infrastructure Canada considered providing financial assistance to the proponent and Fisheries and Oceans Canada considered taking action in relation to subsection 35(2) of the Fisheries Act.
Project Description (as posted in the Notice of Commencement)
The British Columbia Transmission Corporation is proposing to develop and operate a new 287 kV transmission line that would originate at Skeena Substation near Terrace to Bob Quinn Lake. The proposed line would be approximately 335 km long. The proposal also includes upgrading the Skeena Substation and constructing a new substation near Bob Quinn Lake at the northern terminus. Most of the proposed route is on Crown land with the possible exception of portions in the Nass Valley that may run through Nisga'a Lands.
The project, for the purposes of an environmental assessment by Infrastructure Canada includes the physical works and the activities associated with the construction, operation and decommissioning of the project components as described in the Project Description of May, 2007.
The Northwest Transmission Line will include the following components:
- a 287 kV transmission line between Skeena Substation near Terrace, BC and the area of Bob Quinn Lake, BC; and
- 287 kV circuit terminations and related equipment at Skeena Substation and new substation facilities near Bob Quinn Lake.
- clearing and grading of right-of-way development areas including access roads;
- tower erection;
- use of temporary lay-down areas during construction; and
- other related physical works associated with the project.
A decision was taken on May 5, 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.
