Potential Effects:

Potential disturbance to and loss of sensitive caribou habitat Specific Mitigation:

Harvest within caribou range boundary will not include shear blading except for access, conductor stringing trails, and tower footprints.

No shear blading to clear the right of way (ROW) in the sensitive range. Selective cutting methods will only be used to remove danger trees, vegetation within tower footprint, access route, and helicopter access points, to maintain low tree, shrub and herb plant communities on the ROW. Use existing access roads and trails to the extent possible

Maintenance trails to be maintained to reduce line of sight for hunters and predators. Remove trees by low-disturbance methods

Annual ground inspection of towers to occur late in winter season to avoid creating packed snow trails that facilitate predator use of the ROW.

Any Manitoba Hydro constructed or improved access routes used to access the ROW for construction that will not be needed for future maintenance will be decommissioned on completion of construction. Any culverts or road improvements will be removed and the first 100 m from of the trail dug up to the extent possible. Available slash <1 m in height will also be evenly distributed over the access route to reduce the possibility of use by ATV traffic.

E-504973 N-6059662 14N 14805 m

Potential Effects:

Potential disturbance to and loss of sensitive caribou habitat Specific Mitigation:

Harvest within caribou range boundary will not include shear blading except for access, conductor stringing trails, and tower footprints.

No shear blading to clear the right of way (ROW) in the sensitive range. Selective cutting methods will only be used to remove danger trees, vegetation within tower footprint, access route, and helicopter access points, to maintain low tree, shrub and herb plant communities on the ROW. Use existing access roads and trails to the extent possible

Maintenance trails to be maintained to reduce line of sight for hunters and predators. Remove trees by low-disturbance methods

Annual ground inspection of towers to occur late in winter season to avoid creating packed snow trails that facilitate predator use of the ROW.

Any Manitoba Hydro constructed or improved access routes used to access the ROW for construction that will not be needed for future maintenance will be decommissioned on completion of construction. Any culverts or road improvements will be removed and the first 100 m from of the trail dug up to the extent possible. Available slash <1 m in height will also be evenly distributed over the access route to reduce the possibility of use by ATV traffic.

Potential Effects: Melting or loss of permafrost due to disturbance of the active layer Specific Mitigation:

Potential Effects:

Higher risk of wire collision, disturbance during breeding and nesting, risk of wire collision is localized to the right-of-way while construction disturbance can effect colonies up to 400 meters away

Specific Mitigation:

Adhere to reduced risk timing windows for protection of birds (August 1- April 30) Maintain setback during timing window Conduct priority assessment for bird diverters and other measures prior to transmission line stringing Install bird diverters or other measures at high priority sites
