1 Alternative Routes Determined

2 Preferred Route Selection

3 Preferred Route Selection Expert judgment is used to determine the Final Preferred Route Takes into account feedback from Round One engagement and preliminary assessment information Round Two Public Open Houses will provide public feedback on the Final Preferred Route from stakeholders at routing phase and in public and aboriginal engagement

4 Route Selection - Conclusion With the help of stakeholder input, expert judgment and internal expertise, a balanced, transparent and defendable Final Preferred Route is developed.

5 EPRI-GTC* Methodology Stakeholder Calibration Siting Criteria Stakeholders identify/refine and provide relative suitability values (modified Delphi process to gain consensus) Engineering Stakeholders infrastructure co-location Natural Environment Stakeholders natural areas considerations Built Environment Stakeholders land use issues Stakeholders provide relative importance /weights (analytical hierarchy process) Computer-generated corridor models GIS data, moving from general to specific Models for each of the above criteria (5:1:1) Models with Equal weighting Combination Model Expert Judgment (Internal Stakeholders) *Electric Power Research Institute-Georgia Transmission Corp.

6 Benefits of EPRI Process Objective Based on clear identification of criteria by stakeholders Values and weights developed during the process are applied to geographic information As the area of interest becomes more focused and defined, data becomes more detailed and accurate Consistent Algorithms provide replicable results Defensible Understanding what is required and how to do it before determining where to put it

7 Preliminary Structure Design Towers, H-Frame 2 steel columns 6m wide between column Average 300m between towers Height 16m to 39.5m Higher towers at end points and crossings Final tower design may depend on route characteristics

8 Alternative Routes St. Vital to La Verendrye Station - Southern Loop Transmission Corridor In a fixed right-of-way St. Vital to Letellier Station 20 different segments 4 segments common to all routes Goal of Workshops Identify one Preferred Route

13 2.2 Environmental Assessment The Project is considered a Class 2 development under The Environment Act (Manitoba) and will require an Environmental Assessment Report to be completed and submitted to Regulators.

14 Environmental Assessment Environmental Assessment generally consists of: Characterization of the environment Identification of potential effects on people and the environment Stakeholder and public engagement process Determination of methods to avoid or reduce potential adverse effects while enhancing beneficial effects

15 Study Area Characterization The Environmental Assessment will include characterization of the following aspects of the Study Area: Physical Environment (climate, soils, surficial geology, hydrogeology) Aquatic Environment (surface hydrology, water quality, fish and fish habitat) Terrestrial Environment (vegetation, wildlife and habitat) Socio-economic Environment (land use, infrastructure, agriculture and landowners, economy, heritage resources, general concerns/issues with the Project)

16 Study Area Characterization Pasture, NE of Roseau River Entry sign to Crow Wing Trail, near Senkiw Unnamed wetland, near Tourond

17 Valued Environmental Components The Environmental Assessment will determine Valued Environmental Components (VECs) VEC - Any part of the environment that is considered important by the proponent, public, scientists, and government involved in the assessment process; importance may be determined on the basis of societal or cultural values, or scientific interest or concern. VECs are selected by Utilizing experience from other, similar projects Getting input from specialists in the various disciplines Collecting input from interested stakeholders and the public

18 VECs for St. Vital Transmission Complex VECs currently being considered for the St. Vital Transmission Complex Project include: Wildlife Habitat Native Prairie Employment and Business Opportunities Property and Residential Development Aboriginal Lands Agricultural Productivity Agricultural Land Uses Communication and Transportation Human Health Public Safety Aesthetics

19 Examination of Effects To assess the potential environmental effects of the project, the following will be undertaken: Identification and assessment of potential environmental effects of the project on VECs Identification of mitigation measures for environmental effects on VECs Identification of methodology for determining significance of environmental effects on VECs Identification of measurable parameters to quantify and evaluate the significance of environmental effects on VECs An assessment of cumulative effects on identified VECs
