The JdF Cable Project will be located, designed, constructed
and operated in a manner that will avoid and minimize
impacts to the environment both underground and underwater.
Sea Breeze has conducted an environmental assessment
consistent with the Canadian Environmental Assessment
Act for the JdF Cable Project, which is included in the CPCN (Certificate of Public Convenience and Necessity)
application. There was also a review conducted under the National Environmental Policy Act by the U.S. Department of Energy that led to the issuance of an Environmental Impact Statement.
The chosen technology and installation techniques
allow for flexibility and enable us to factor in such
considerations as spawning seasons and bird breeding
as well as culturally or archaeologically valuable
sites.
Submarine Considerations:
- The cables would have minimal environmental impact
at the time of burial, and no substantial, harmful long-term environmental effects are expected.
- Unlike many submarine transmission lines, HVDC Light® cables
are not oil cooled and do not pose any danger of coolant leaks or spills.
- The buried cable is not likely to create a physical
barrier that could interfere with crab migration,
fish spawning, or the use of existing habitats or
nursery areas.
- The submarine cable would
be buried where conditions permit, and would not
interfere with navigation or commercial and recreational
activities.
- Directional drilling would bore a hole
to carry the cable from land to sea. The
directional drill is expected to exit deep enough
to avoid impact to kelp beds and other intertidal
and foreshore habitat.
- Disruption to the marine floor
will be localized and short term, and recovery to
pre-disturbance conditions will occur rapidly as
organisms re-colonize the areas.
- Buried
submarine cable will not affect coastal deposition
or erosion and is not expected to have any adverse
impacts to fisheries resources during operation.
- Juvenile
and adult fish are mobile and can avoid the work
areas during cable installation.
The following field studies have been undertaken as
part of our Environmental Assessment:
Marine field studies:
- Archaeological
- Geotechnical
- Near shore:
Terrestrial Considerations:
- The cables on land would be buried in
a narrow trench under existing roads, rights-of-way,
or existing utility corridors.
- The converter station near Pike Lake, northwest
of Victoria would be located near an existing BC
Hydro electrical substation in an undeveloped area. The
station would be planned and designed to minimize
environmental impacts.
