of an Environmental Assessment
Hydroelectric Facilities, Kabinakagami River, Cochrane District
December 14, 2011 — Fisheries and Oceans Canada and Transport Canada are required to ensure that a screening is conducted pursuant to the Canadian Environmental Assessment Act commencing on December 12, 2011 in relation to the project: Hydroelectric Facilities, Kabinakagami River, Cochrane District.
Northland Power Inc. and Constance Lake First Nation (CLFN) are proposing to construct and operate four (4) run-of-river hydroelectric facilities on the Kabinakagami River, north of Highway 11, approximately 30 km west of Hearst, Ontario. The four proposed sites include: Neeskah (Site 3); Peeshoo (Site 4); Wahpeestan (Site 5); and Wapoose (Site 6). Each site will consist of an earth-fill dam and a concrete overflow spillway (either 50 or 70 m long depending on the site), a powerhouse and intake and tailrace channels. The dams will create head ponds of 7 ha, 6 ha, 43 ha and 21 ha respectively. The powerhouse at each site will be located on the west bank of the river and sized to contain two pit-type turbine generating units each with a 3.25-MW capacity. The total installed capacity at each site will be 6.5 MW and the total installed capacity for all four sites combined will be 26 MW. Access to the project sites will be from Highway 11 and Highway 663 along Rogers Road and Pelican Road to Neeskah (Site 3). Two approximately 300 m sections of new access road will be developed to tie the existing Pelican Road into the Neeskah (Site 3) and Peeshoo (Site 4) facilities. A new approximately 8 km long access road will be required to connect Pelican Road to the Wahpeestan (Site 5) and Wapoose (Site 6) sites. All permanent and temporary access will be from the west bank of the river only. Preliminary transmission routing will consist of a single 44-kV line from Wapoose (Site 6) south along the new access road to Neeskah (Site 3) and then through a new corridor (approximately 22 km) to the existing substation at the Calstock Power Plant.
