The Eastern Mainline Project team understands the important role all aquifers, rivers and lakes play in maintaining sensitive and vital ecosystems in Ontario. Aquifers are important sources of drinking water, and rivers and lakes provide habitats for fish and wildlife, including species at risk. Rivers and lakes also provide valuable recreation opportunities such as boating and fishing for local communities to enjoy.
TransCanada will use the information from our open houses, meetings with landowners, regulatory agencies and Aboriginal communities, along with environmental studies to understand the potential impacts the Project may have. Appropriate mitigation strategies will be put in place.
Aquifers, Rivers and Lakes Will Be Protected During Construction
The Eastern Mainline Project has carefully considered and will continue to study these important bodies of water during project routing and design. Wherever possible, crossings of these features are avoided or located so that any possible disturbances are minimized.
Project planning will include environmental desktop and field studies, as well as consultation with the public, other stakeholders, and regulatory agencies at the provincial and federal levels to gather site specific information to include as part of the Environmental and Socio-Economic Assessment.
Design, construction and method of crossing will be based on industry-proven construction techniques, information gathered from studies and stakeholders, input from engagement activities and regulatory compliance requirements.
Additional protective design features, such as heavy-walled pipe and burying the pipe deep in the ground are applied at watercourse crossings. Mitigation measures to be implemented during construction, such as effective sediment and erosion control mechanisms, measures to protect fish and fish habitat, and reclamation plans aimed at re-establishing biological diversity and habitat will be developed and included in the Environmental and Socio-Economic Assessment and Environmental Protection Plan.
The Eastern Mainline Project will conduct post-construction monitoring to confirm the effectiveness of the mitigation and respond to any areas that require additional mitigation work.
