| Issue |
|
Resolution |
| Employment, local infrastructure |
|
labour and
materials to be sourced locally where possible |
|
local businesses (accommodation, food, gas, etc) will
benefit |
| |
|
|
|
|
| Release of sediment into river during construction of weir, intake
diversion channel, tunnel and powerhouse |
|
most of major works (diversion channel, tunnel, intake
and spillway structure, powerhouse and tailrace channel) will be
construted in the dry |
|
conduct in-stream work after June 20 (during low flows)
to protect fish spanwning and incubation - unless approval obtained
from DFO/MNR to work outside these dates |
|
sediment control plan to be submitted to MNR for approval
and must be followed by contractor |
|
minimize in-stream activities by working behind cofferdams |
| |
|
|
|
|
| Blasting of bedrock for powerhouse outlet |
|
avoid spring spawning periods |
|
use of blast mats where required |
|
minimize any in-stream blasting by maintaining 'rock
plugs' |
|
obtain DFO approval prior to any in-stream activity |
| |
|
|
|
|
| Loss of timber and terrestrial habitat during construction of
power facilities including transmission line and access road |
|
harvest all merchantable timber under direction of the
Sustainable Forest Licencee |
|
avoid spring nesting periods (winter harvest preferred) |
|
loss of terrestrial habitat not mitigable |
|
no in-stream work will be required |
| |
|
|
|
|
Conflict between canoeists and construction traffic along access
road/portage routes
|
|
escort service along portage route to be provided for canoeists
throughout construction period |
|
new trail established to bypass active work areas |
| |
|
| |
|
|
|
|
| Disturbance of archaeological/heritage sites |
|
stage 1 and 2 Archeological/Heritage Assessment undertaken -
area has low potential |
|
If any sites are discovered during construction, stop work and
recover artifacts through archaeological investigations |
| |
|
|
|
|
| General construction activities |
|
any fuels/chemicals stored on site to be bermed and kept a minimum
of 100 m from the water's edge |
|
all wastes to be collected and disposed at approved facilities |
|
site clean-up and restoration following construction activities |

| Issue |
|
Resolution |
Reduced water flows
in the falls reach of the river resulting in:
 loss of
aquatic habitat |
|
presently no fish access to gorge due to high flow
velocity and steep river bottom gradient |
|
minimum flow to be maintained over the falls for
aquatic habitat |
|
submit mitigation/compensation plan to DFO/MNR for
approval, monitor to ensure measures are effective |
| aesthetics |
|
overflow weir not visible from popular downstream
viewing area |
|
aesthetics of alls flows reduced, particularly during
dry periods |
|
enhanced flow from june 15 to September 15 (additional
5 cubic metres per second from noon to 9:00pm) to improve aesthetics |
|
|
|
Headpond
potential increase
in nutrient/metal levels due to inundation |
|
no measurable increase in nutrients or metals anticipated
as a result of high flow through/quick turnover time and small
headpond area; monitor and confirm |
| loss of terrestrial
habitat |
|
approximately 2.0 ha loss of terrestrial habitat
- increased wetted area (3.2 ha) will provide new aquatic habitat |
|
|
|
| Impact to water quality/domestic water supply users |
|
no domestic water supply users within the study area
of immediately downstream |
|
no effects predicted downstream of the development |
|
water quality to be monitored after construction
and compared to baseline data to ensure no significant impacts.
If any changes noted remedial measures may be required |
|
|
|
| Employment/Infrastructure |
|
2-3 operational/maintenance staff required |
|
payment of local taxes |
|
|
|
| Impact on canoe portage route |
|
no change to start or end of portage trail (to bypass falls/gorge) |
|
interpretive displays at intake and powerhouse |
|
alternative portage route proposed by BPC for opposite shore
(SE side of river) |
|
potential for shuttle service to White Lake and/or Pukaskwa park |
|
BPC proposal to improve signage and undertake maintenance of
camping areas along part of the canoe route |
