ALTERNATIVE ROUTE ASSESSMENT AROUND LOON LAKE EAST-WEST TIE TRANSMISSION PROJECT
1. INTRODUCTION NextBridge Infrastructure LP (NextBridge) is proposing to construct, own, and maintain the East-West Tie Transmission Project (the Project). The Project is a new, approximately 450 kilometre (km) long double-circuit 230-kilovolt ( kV) transmission line that connects the Lakehead Transformer Station (TS) in the Municipality of Shuniah, near the City of Thunder Bay, to the Wawa TS located east of the Municipality of Wawa (with a connection at the Marathon TS, in the Town of Marathon).
The Project has been identified as a priority project by the Province of Ontario, and a needed project by the Independent Electricity System Operator (IESO, formerly the Ontario Power Authority [OPA; On January 1, 2015, the OPA merged with the IESO to create a new organization that combines the OPA and IESO mandates.]) to meet future electricity demand in northwestern Ontario.
The Project is subject to Ontario’s Individual Environmental Assessment (EA) process based on the voltage and length. A Terms of Reference (ToR) for the Individual EA was submitted to the Ministry of the Environment and Climate Change (MOECC) in February 2014 and approved in August 2014. Subsequently, an EA Report has been prepared in accordance with the approved ToR.
The preliminary preferred route for the Project was identified by comparing the routes that were originally proposed by NextBridge during the Ontario Energy Board’s (OEB) competitive bid process (i.e., the Reference Route that generally parallels the existing East-West Tie line and three alternative route segments around certain federal lands) with a series of 37 additional alternative route segments, as requested by the Ministry of Natural Resources and Forestry (MNRF) and other stakeholders. The alternative route assessment used the criteria and indicators provided in the approved ToR to identify the route that is preferred from environmental, socio-economic, and technical perspectives (i.e., more advantages than disadvantages).
Consultation on the preliminary preferred route with local residents, landowners, and fishing club representatives near Loon Lake, including feedback received at the second and third round of Open Houses, resulted in identification of alternative route segments around Loon Lake. This report focuses on the assessment of these Loon Lake alternative route segments. The objective of this assessment is to confirm the option in the vicinity of Loon Lake with the best balance of environmental, socio-economic, and technical advantages compared to other alternatives, which will be the preferred route.
2. BACKGROUND 2.1 Previous Evaluation of Alternatives The Reference Route (as defined in the EA Report) and three alternative routes to avoid certain federal lands (two First Nation reserves and Pukaskwa National Park) were identified by NextBridge as part of a screening process completed during the bid process organized by the OEB. The Reference Route, which generally parallels the existing East-West Tie line, is consistent with the 2014 Provincial Policy Statement (Government of Ontario 2014), which recommends making the best use of existing infrastructure and corridors, and that infrastructure be provided in a coordinated, efficient, and cost-effective manner before proposing new greenfield (i.e., parcel of land that has not been previously developed [Heid 2004]) developments that do not parallel existing developments. This was one of the OPA’s considerations in selecting the Reference Route (also referred to as the Reference Option by the OPA) and is consistent with the direction to other electricity transmitters in the past from provincial agencies and ministries to make use of existing rights-of-way (ROWs) and corridors before seeking approvals for

ALTERNATIVE ROUTE ASSESSMENT AROUND LOON LAKE EAST-WEST TIE TRANSMISSION PROJECT
greenfield routes (i.e., not adjacent to existing infrastructure). The Reference Route was identified based on the following:
The IESO and OEB identified and acknowledged the Reference Route.
The bidding process to select a designated transmitter focused on the Reference Route.
NextBridge examined the Reference Route during the bidding process.
The Reference Route is the shortest distance to connect the Lakehead TS and Wawa TS with a connection at Marathon TS (following existing transmission facilities).
The use of the Reference Route is consistent with provincial policy as it is generally adjacent to the existing East-West Tie line ROW.
It was determined that additional alternative route segments should be identified and assessed as potential alternatives to the Reference Route to confirm the best route from an environmental, socio-economic, and technical perspective based on comments received during the ToR phase. The Township of Dorion also requested that NextBridge review additional alternative route segments to avoid affecting private property in the Dorion area and potential effects to the Ouimet Canyon area. In December 2015, NextBridge produced the alternative route report (NextBridge 2015), which included an evaluation of alternative route segments, as requested by the MNRF and other stakeholders. The Reference Route was assessed in each area in comparison to alternative route segments representing other route options to identify the preliminary preferred route.
NextBridge determined, based on the assessment, that with two exceptions the preliminary preferred route is generally adjacent to the existing East-West Tie line, and it has more advantages and fewer disadvantages than the alternative route segments. The first exception relates to Pukaskwa National Park. Given that Parks Canada has determined that it is not prepared to authorize access to study a new transmission line through Pukaskwa National Park, the alternative around the park that is adjacent to a 115 kV transmission line and logging roads and crosses a cutover area is considered the best feasible alternative and therefore, forms part of the preliminary preferred route. Also, based on feedback received through public consultation with the residents of the Township of Dorion and the results of the desktop Geographic Information Systems (GIS)-based analysis, routing to the west of Ouimet Canyon Provincial Park is generally preferred in this area and has been identified as part of the preliminary preferred route.
Additional alternative route segments around provincial parks and conservation reserves were identified and assessed in response to feedback on the assessment from the MNRF. This additional assessment is included in the EA Report (Appendix 3-I-B) and confirmed that the preliminary preferred route has more advantages and fewer disadvantages than the additional alternative route segments.
2.2 Identification of Further Alternative Route Segments NextBridge was presented with two alternative route segments by Loon Lake community members, the Damphino Fishing Club, and the North Shore Fishing Club at a meeting held July 26, 2016, at the West Loon Lake Community Centre. A third alternative route segment was forwarded to NextBridge on July 27, 2016.
Through discussion at the meeting, and follow-up discussions, one of the alternative route segments was identified as the preferred alternative by Loon Lake stakeholders. NextBridge proposed some minor refinements to improve constructability of this particular alternative and it was then assessed as an additional alternative route segment. This additional alternative route segment is the focus of this report. This alternative route segment, along with the preliminary preferred route segment around Loon Lake, are shown in Appendix A.

3. APPROACH FOR THE EVALUATION OF ALTERNATIVE ROUTE SEGMENTS
The following sections summarize the method used for the identification, evaluation, and selection of the preferred alternative route segment around Loon Lake.
3.1 Overall Method A similar method to that applied by NextBridge (2015) was used for this analysis. The general routing criteria (Table 1 from NextBridge 2015; Appendix 3-I), the preference for existing linear ROWs with consideration of the limitations associated with paralleling certain types of existing infrastructure was considered (e.g., minimum separation distances), and the two-step process for comparison using assessment criteria and indicators as well as screening criteria (MOECC 2014) were applied in identifying and assessing additional route segments. Each alternative had to meet the screening criteria listed in the MOECC (2014) Code of Practice: Preparing and Reviewing Terms of Reference for Environmental Assessments in Ontario criteria to be carried forward.
Data for the comparative evaluation presented in Section 4 were derived from available GIS databases and supplemented by air photo interpretation where possible. For some linear feature types (e.g., rail lines, roads, trails, and water bodies) that are crossed multiple times, the feature is only reported (Appendix A) as a single crossing per alternative. The GIS-based information used for this assessment may not be as detailed as that presented in the EA Report.
3.2 Alternatives Assessment Criteria and Indicators The alternatives assessment criteria and indicators that were used in the alternative route report (NextBridge 2015) were used to assess the new alternative route segment.
4. COMPARATIVE EVALUATION OF ALTERNATIVE ROUTE SEGMENTS
This section presents the comparative evaluation of the alternative route segments around Loon Lake. Criteria and indicator tables used to support the analysis are presented in Appendix B. All the criteria and indicators were evaluated with the focus of the discussion on advantages and disadvantages and notable differences between route segments. The advantages and disadvantages of each route segment are presented in Table 4-1.
The advantages of the alternative route segment around Loon Lake are that it is the shortest route segment, has the smallest area of overlap with potential aggregate resources, has the smallest area of overlap with mapped water bodies (not including water bodies), has the largest area of overlap with previous logging disturbance, crosses the least number of roads, and is preferred by Loon Lake community members.
For these reasons, the alternative route segment around Loon Lake is considered the best alternative.

ALTERNATIVE ROUTE ASSESSMENT AROUND LOON LAKE EAST-WEST TIE TRANSMISSION PROJECT
5. CONCLUSION The assessment of alternative route segments around Loon Lake resulted in the identification of a preferred alternative route segment in this area. The preferred alternative route segment around Loon Lake is the alternative route segment identified by Loon Lake stakeholders as the preferred alternative, with minor refinements to improve constructability. This alternative route segment is the shortest route segment, has the smallest area of overlap with potential aggregate resources, has the smallest area of overlap with mapped water bodies (not including water bodies), has the largest area of overlap with previous logging disturbance, crosses the least number of roads, requires the least number of transmission line corners, requires the least number of transmission line crossovers, and has the most advantages when compared to the preliminary preferred route.
Incorporation of this alternative route segment into the preferred route represents a local route refinement from the preliminary preferred route. The preferred route, including this local route refinement, is assessed in the EA Report.
