KEY ORGANIZATIONS
Builds, owns, operates and maintains electricity transmission and distribution facilities across Ontario.
Develops plans to ensure electricity needs are met for the benefit of Ontario, both now and in the future.
Ministry of Environment Conservation and Parks
Reviews the environmental assessment process to ensure potential environmental effects are considered before an infrastructure project begins.
PROJECT OVERVIEW The IESO completed an assessment of the electrical load forecast for Essex County and requested Hydro One to construct a new switching station which will help meet the growing needs of the area.
Hydro One has also identified the need for additional transformers, in order to supply more low-voltage electricity to homes and businesses in the area.
The proposed Lakeshore Transmission Stations Project will involve a new 230 kV switching station and a separate 230/27.6 kV Transformer Station, which together will:
• Improve reliability of the transmission system in Essex County, and;
• Supply the distribution system which carries power to local homes and businesses.
CLASS ENVIRONMENTAL ASSESSMENT • The project is subject to the Class Environmental Assessment for
Minor Transmission Facilities (Hydro One, 2016) process, in accordance with the Ontario Environmental Assessment Act.
• This process ensures that transmission projects that have a predictable range of effects are planned and carried out in an environmentally acceptable manner.
• The Class EA process includes:
• Consultation with municipal, provincial and federal government officials; government agencies; First Nation and Métis communities; potentially affected and interested persons, affected businesses and interest groups.
• Collection of environmental inventory data and description of the existing baseline conditions.
• Identification and evaluation of alternative methods of undertaking the project.
• Identification of potential environmental effects of the project and mitigation measures.
CLASS ENVIRONMENTAL ASSESSMENT • As part of the Class EA process, a draft Environmental Study
Report (ESR) will be made available for a 30-day public review and comment period. An ESR is an easy-to-follow record of the decision making process and generally includes:
• A description of the need for the project;
• A description of the existing environment;
• The preferred solution;
• The rationale behind the selection of the preferred solution;
• A description of the Indigenous and stakeholder consultation undertaken; and,
• A description of the potential environmental effects of the preferred solution and mitigation measures to address these effects.
• Hydro One will make best efforts to resolve concerns raised during public consultation and the draft ESR review period, prior to filing the final ESR with the Ontario Ministry of the Environment, Conservation and Parks (MECP).
• If a concern cannot be resolved, the concerned party may submit a written request (“Part II Order Request”) to the MECP during the public review period to request a higher level of assessment, known as an Individual Environmental Assessment.
CLASS EA STUDY AREA The proposed Lakeshore TS location is best suited to be near the existing Leamington Junction (JCT), where the existing 230kV circuits join.

The study is bounded by Middle Road to the north, Rochester Townline Road to the east, South Middle Road to the south, and will extend west approximately 550 metres from the Leamington JCT.
STATION CONFIGURATIONS Hydro One has identified one technically feasible configuration for the 230 kV switching station and assessed three feasible configurations for the locations of the transformer station.
Based on the research and consultation to date, the preferred location of the transformer station has been selected.

PREFERRED CONFIGURATION
CONSTRUCTION ACTIVITIES The construction phase for the project will involve the following activities:
• Site preparation such as vegetation removal, grading, temporary access and laydown area
• Construction of temporary 230 kV bypass line to ensure continued power
• Installation of station fences, entrances, concrete foundations and station drainage
• Installation of new transmission line structures and station electrical equipment
• Delivery and installation of new transformers
• Connection of transmission lines and station electrical equipment, testing and commissioning
• Site clean up and reclamation
• Hydro One will be installing additional distribution lines to carry power from the new stations to the customers in the vicinity. These distribution power lines are expected to be on the road allowance of South Middle Rd, County Rd 31, Lakeshore Rd 243, Lakeshore Rd 245, and Rochester Townline road. Hydro One will be contacting affected property owners and road authorities in advance of construction.
MINIMIZING CONSTRUCTION AND PROJECT EFFECTS The following mitigation measures will be implemented to minimize potential construction and project effects:
• Dust, sediment and erosion controls, as required
• Hydro One will work in accordance with local bylaws with respect to noise and working hours, and if necessary obtain permit(s)
• Hydro One will minimize effects to existing agricultural resources to the extent feasible
• Landscaping and visual screening
• Hydro One does not anticipate power interruptions during construction of the switching and transformer stations.

NEXT STEPS • Hydro One will complete environmental surveys within the study
area to complete the identification of potential environmental effects.
• Hydro One will continue to consult Indigenous communities, government agencies, municipal staff, elected officials, interest groups and the public to obtain feedback and answer questions about the project.
• Hydro One will release a Draft Environmental Study Report (ESR) for a 30 day public review, anticipated for release later this fall.
• If no Part II Order Requests are submitted during the 30 day review period, Hydro One will file the final ESR with the Ministry of the Environment, Conservation and Parks, concluding the Class EA.
