NOTICE OF COMMENCEMENT
of an Environmental Assessment
Larder and Raven Hydroelectric Generating Station, Larder River, McFadden Township
Raven Falls (ON)
June 8, 2011 — Fisheries and Oceans Canada and Transport Canada are required to ensure that a screening is conducted commencing on May 27, 2011 in relation to the development proposal: Larder and Raven Hydroelectric Generating Station, Larder River, McFadden Township.
Xeneca Power Development Inc. is proposing to construct and operate a hydroelectric generating station on the Larder River, immediately upstream of Raven Falls, 100 m upstream of the existing Raven Dam and 1.4 km downstream of the existing Larder Lake Control Dam, located in the Township of McFadden, District of Timiskaming. The proposed development would be operated as a run-of-river facility with some daily flow modifications and will have a generating capacity of 1.25 MW. The project would involve the construction of an earthen dam with a central concrete sluice gate as well as an intake that would direct water through a penstock to the powerhouse. The facility would capture 18 m of surveyed gross head and would result in the flooding of approximately 22 ha of riparian lands up to 1.9 km upstream of the dam. In association with the new development, the Raven Dam and the Larder Lake Control Dam will be removed, modified, replaced or otherwise decommissioned. The proposed project would connect to the electrical grid via a new 44 kV power line, supported by wooden piles, approximately 16 km in length. The required right-of-way for the power line corridor would extend from 10-30 m dependant on site characteristics. One pad mount transformer would be required. Access to the proposed site would require upgrading 1.8 km of existing road east of Highway 624 and the construction of 7.3 km of new access road, running east from the highway.
The scope of the project has been identified as: all physical works and activities associated with the construction and operation of the proposed hydroelectric generating facility, including removing, modifying, replacing and/or otherwise decommissioning the Raven Dam and the Larder Lake Control Dam, construction of a new earthen dam/concrete sluice gate, intake, penstock and powerhouse, associated storage sites, working areas, platforms, new transmission line and associated structures, new access roads, upgrades to existing access roads and any other works or undertakings directly associated with the hydroelectric project, including those that are temporary.
Under section 5 of the Canadian Environmental Assessment Act, an environmental assessment is required because, for the purpose of enabling the project to be carried out in whole or in part, Fisheries and Oceans Canada may take action in relation to subsection 35(2) of the Fisheries Act, may take action in relation to section 32 of the Fisheries Act, may take action in relation to subsection 22(3) of the Fisheries Act and may take action in relation to subsection 22(1) of the Fisheries Act and because Transport Canada may take action in relation to section 5 of the Navigable Waters Protection Act.
This project is also subject to the environmental assessment requirements of the Government of Ontario.
The Canadian Environmental Assessment Agency will act as the Federal Environmental Assessment Coordinator for this environmental assessment.
