CHATHAM, ONT. — The draft environmental study report (ESR) for the St. Clair Transmission Line project was recently released by Hydro One for public review and comment.
Hydro One has been working closely with Indigenous communities, residents, directly impacted property owners and businesses and is encouraging interested parties to submit feedback on the draft ESR report from now until Dec. 7.
The report details engagement during the Class Environmental Assessment (EA), the route selection process, identifies potential effects to the natural and socio-economic environments and measures Hydro One will use to avoid, minimize or restore any negative effects of the project, states a release.
The draft report relies on information collected from a field study program with more than 85 sites visited and with almost two years of work, study and community engagement. Overall, the report concludes potential effects can be effectively managed using industry standard environmental mitigation measures, the release indicates.
The transmission line is expected to bring a number of benefits to the region including a 50/50 equity partnership in the line component for five local First Nations; an additional 450 megawatts of clean electricity, bringing approximately enough energy to power a city the size of London, Ont.; increased reliability and resiliency of energy supply; and increased economic growth in the Windsor-Essex and Chatham area in sectors like agriculture and electric vehicle technology.
The St. Clair Transmission Line is a proposed new double-circuit 230 kilovolt transmission line between the Lambton Transformer Station (TS) in St. Clair Township and the Chatham Switching Station (SS) in the Municipality of Chatham-Kent.
Hydro One found Route 2, the preferred route option, had the least effect on the values of importance to Indigenous communities as well as to the natural environment, agricultural lands and operations. As part of the Class EA, the expansion of Lambton TS and Chatham SS is also proposed, as well as an upgrade to the Wallaceburg Transformer Station which will increase the transmission reliability and resiliency for the Wallaceburg area, the release adds.
