Leaside to Main Infrastructure Refurbishment
The replacement of underground cables was planned in accordance with the approved Class Environmental Assessment for Minor Transmission Facilities (Class EA). The Class EA was developed as a streamlined process to ensure that minor transmission projects that have a predictable range of effects are planned and carried out in an environmentally acceptable manner. Through the Class EA, two options for the underground cable replacement between Leaside TS and Todmorden JCT were assessed. No feasible alternatives were identified for the underground cable replacement between Main TS and Lumsden JCT.Consultation with elected officials, municipal representatives, government agencies, First Nations communities, interest groups and the public is an important part of the Class EA process. As part of the consultation process, our team held two rounds of Public Information Centres and community walks in project areas. In addition, a draft Environmental Study Report (ESR) was made available for a 47-day review and comment period. Details of the review process were communicated through various channels, including local newspapers, project website, and notification to project stakeholders. The Final Environmental Study Report for the project is available below.
