Site C Clean Energy Project

Description of the Designated Project

BC Hydro and Power Authority (the Proponent) proposes to construct and operate a dam and 1,100-megawatt hydroelectric generating station on the Peace River in northeastern British Columbia. The Site C Clean Energy Project (the Designated Project) would be the third in a series of dams on the Peace River in British Columbia. The project components would consist of an earthfill dam 1,050 metres long and 60 metres high, a 1,100-megawatt generating station and associated structures, a 83-kilometre long reservoir, realignment of four sections of Highway 29, and two 77-kilometre transmission lines along an existing transmission line right-of-way connecting Site C to Peace Canyon.

Conduct of the Environmental Assessment

The former Minister of the Environment established a Joint Review Panel for the Site C Clean Energy Project with the Government of British Columbia. The Joint Review Panel commenced its work on August 2, 2013. The Joint Review Panel conducted its review in a manner that met the requirements of the Canadian Environmental Assessment Act, 2012 (CEAA 2012) and submitted its report to me in my capacity as Minister of the Environment on May 1, 2014.

Decision on Environmental Effects referred to in subsection 5(1) of CEAA 2012

In accordance with paragraph 52(1)(a) of CEAA 2012, after considering the report of the Review Panel on the Site C Clean Energy Project and the implementation of mitigation measures that I consider appropriate, I determined that the Designated Project is likely to cause significant adverse environmental effects referred to in subsection 5(1) of CEAA 2012.

In accordance with subsection 52(2) of CEAA 2012, I referred to the Governor in Council the matter of whether those significant adverse environmental effects were justified in the circumstances.

In accordance with paragraph 52(4) (a) of CEAA 2012, the Governor in Council decided that the significant adverse environmental effects that the Designated Project is likely to cause are justified in the circumstances.

In accordance with subsection 53(1) of CEAA 2012, I have established the conditions below in relation to the environmental effects referred to in subsection 5(1) of CEAA 2012, with which BC Hydro and Power Authority must comply.

Decision on environmental effects referred to in subsection 5(2) of CEAA 2012

The carrying out of the Designated Project may require the following federal authorities to exercise a power or perform a duty or function conferred on them under an Act of Parliament other than CEAA 2012:

  • Fisheries and Oceans Canada may issue an authorization under subsection 35(2)(b) of the Fisheries Act; and
  • Transport Canada may approve the dam and ancillary works under subsection 6(1) of the Navigation Protection Act (NPA) and may permit ancillary works under subsection 9(1) of the NPA.

In accordance with paragraph 52(1)(b) of CEAA 2012, after considering the report of the Review Panel on the Site C Clean Energy Project and the implementation of mitigation measures that I consider appropriate, I determined that the Designated Project is likely to cause significant adverse environmental effects referred to in subsection 5(2) of CEAA 2012.

In accordance with subsection 52(2) of CEAA 2012, I referred to the Governor in Council the matter of whether those significant adverse environmental effects were justified in the circumstances.

In accordance with paragraph 52(4) (a) of CEAA 2012, the Governor in Council decided that the significant adverse environmental effects that the Designated Project is likely to cause are justified in the circumstances.

In accordance with subsection 53(2) of CEAA 2012, I have established the conditions below in relation to the environmental effects referred to in subsection 5(2) of CEAA 2012, with which BC Hydro and Power Authority must comply.

15.3. The plan shall include:

15.3.1. procedures to continue inventories and ground truthing of potential physical and cultural heritage resources to determine the need and applicability of mitigation measures;

15.3.2. measures to address the effects of the Designated Project on the physical and cultural heritage and to structures, sites or things that that have been identified as being of historical, archaeological, paleontological or architectural significance by local stakeholders, relevant organizations, Reservoir Area Aboriginal groups and the Métis Nation British Columbia;

15.3.3. procedures to monitor reservoir erosion during occurrences of low reservoir levels, to investigate any potentially new-found sites and to carry out emergency salvage procedures during construction and operation; and

15.3.4. procedures to monitor shoreline erosion downstream of the Site C dam for up to 2.5 kilometres during the first two years of operation to determine if physical heritage resources are affected.

15.4. The Proponent shall submit to the Agency, Reservoir Area Aboriginal groups and the Métis Nation British Columbia a draft copy of the plan for review 90 days prior to initiating construction.

15.5. The Proponent shall submit to the Agency the final plan a minimum of 30 days prior to initiating construction. When submitting the final plan, the Proponent shall provide to the Agency, an analysis that demonstrates how it has appropriately considered the input, views or information received from Reservoir Area Aboriginal groups and the Métis Nation British Columbia.

15.6. The Proponent shall implement the plan and provide to the Agency an analysis and summary of the implementation of the plan, as well as any amendments made to the plan in response to the results, on an annual basis during construction and for the first five years of operation, unless otherwise indicated.

16. Species at risk, at-risk and sensitive ecological communities and rare plants

16.1. The Proponent shall ensure that potential effects of the Designated Project on species at risk, at-risk and sensitive ecological communities and rare plants are addressed and monitored.

16.2. The Proponent shall develop, in consultation with Environment Canada, a plan setting out measures to address potential effects of the Designated Project on species at risk, at-risk and sensitive ecological communities and rare plants.

16.3. The plan shall include:

16.3.1. field work to verify the modeled results for surveyed species at risk and determine the habitat that would be permanently lost, habitat that would be fragmented and habitat that would remain intact for those species, including the Short-eared Owl, the Western Toad and the Myotis Bat species;

16.3.2. surveys to determine whether the rare plant species potentially facing extirpation in the Project Activity Zone are found elsewhere in the region;
