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

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.
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
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)
Study Area Characterization
Entry sign to Crow Wing Trail, near Senkiw
Pasture, NE of Roseau River
Unnamed wetland, near Tourond
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
VECs for St. Vital Transmission Complex
VECs currently being considered for the St. VitalTransmission 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
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
2.3. Public Engagement Program
• Key Person Interviews – over 70 contacts • Stakeholder Workshops – 3 locations • Two Rounds of Public Open Houses – 4 locations
– Winnipeg, Mitchell, Dominion City and Oak Bluff
• Website • Newsletters and Advertising • Direct Mailings• Meetings
