Class Environmental Assessment for Minor Transmission Facilities
A Class Environmental Assessment (Class EA) is an environmental planning process approved under Ontario's Environmental Assessment Act (EAA) for certain classes (groups) of projects that have predictable and manageable environmental effects. A proponent who receives approval for a project planned in accordance with a Class EA (provided the project is eligible to follow that process) does not need to obtain separate approval under the EAA.
The Class EA for Minor Transmission Facilities applies to certain transmission facilities (lines and stations) and was originally developed by the former Ontario Hydro and approved under the EAA by Order-in-Council in 1980. It has undergone several revisions since that time. The current version of the document approved by the Minister of the Environment, Conservation and Parks, is the Class EA for Minor Transmission Facilities (July 2022).
Class EA Amendment Process
On July 12, 2022, the Minister of the Environment, Conservation and Parks approved amendments to the Class EA for Minor Transmission Facilities. Read the Minister's Notice of Approval, July 12, 2022.
Monitoring the effectiveness of the class ea process
Hydro One is responsible for monitoring the effectiveness of the Class EA Process by ensuring that the document remains relevant and current. As noted in Section 5.5 of the Class EA Document, Hydro One will produce a consolidated annual monitoring report including information provided by all project proponents who use the Class EA in that calendar year.
2022 Annual Monitoring Report was filed with the MECP on May 18, 2023.
All project proponents are required to provide their information for the annual monitoring report to Hydro One by the end of February each year using the required reporting format provided in Appendix H of the Class EA document. Project proponents may submit their information by email to: ClassEA.AnnualMonitoringReport@HydroOne.com.
In addition, Hydro One will undertake a review of the Class EA Document every five years as noted in Section 5.6. This process will ensure that the Class EA Document remains compliant with applicable legislation (incl. the EAA), regulations and policies.
