Draft Environmental Study Report (ESR) for the Leaside to Main Infrastructure Refurbishment Project

Available for public comment until November 14, 2016

Earlier  this year, Hydro  One Networks Inc. (Hydro  One) initiated a Class  Environmental Assessment (EA) for the Leaside  to Main Infrastructure Refurbishment Project, to replace aging  underground transmission cables  in eastern  downtown Toronto. This  work  is required to maintain a safe and reliable

supply  of electricity to the area. Hydro  One has now completed the draft  Environmental Study  Report  (ESR), which  will be available for a 47-day  public  review  and comment period  beginning on September 29, 2016.

The proposed undertaking consists of:

  • Replacing the underground cable  between Leaside  Transformer Station  (TS) and Todmorden Junction (JCT). Hydro  One has selected  a preferred routing option  as shown  on the map and documented in the draft  ESR; and
  • Replacing the underground cable  between Main TS and Lumsden JCT along  the existing route, as no feasible alternatives were identified.

The replacement of underground cable  is subject  to the Class  EA for Minor  Transmission Facilities (Ontario Hydro, 1992). Pending the necessary approvals, construction could begin  in mid-2017.

Our consultations on this project  have included the replacement of overhead shield  wire  between Todmorden JCT and Lumsden JCT, which  Hydro  One had originally planned to complete at the same time as the underground cable  replacement. The work  on the shield wire  has now been postponed and will no longer  be assessed in the draft  ESR. Hydro  One is currently re-evaluating this work  to identify opportunities to combine the shield  wire  replacement with  future refurbishment activities that may be required in the same  area. The release  of the draft  ESR, originally scheduled for early September, was deferred to incorporate this change. Nearby  residents and stakeholders will be notified when  more information about  the overhead line work  is available.

Hydro One will respond to and make best efforts to resolve any issues raised  by concerned parties during the public review  period. If no concerns are expressed, Hydro One will finalize the ESR and file it with  the Ministry of the Environment and Climate Change.

The project  will then be considered acceptable and may proceed as outlined in the ESR.

The Environmental Assessment Act has provisions that allow interested parties to ask for a higher level of assessment for a Class Environmental Assessment project if they feel that outstanding issues have not been adequately addressed by Hydro One. This is referred to as a Part II Order request. Such requests must  be addressed in writing to the Minister of the Environment and Climate Change, as well as the Director of the Environmental Approvals Branch  and received no later than 4:30 p.m. on November  14, 2016, at the following addresses:
