Managing the Environmental Impact

To manage the effect that the Energy East Pipeline project will have on the environment, TransCanada is conducting an Environmental and Socio-Economic Assessment (ESA) and developing a project-specific Environmental Protection Plan (EPP). Both the ESA and EPP are subject to regulatory approval.

Our approach includes:

  • Collecting information about the local environment to help plan construction, and identify appropriate measures, in the EPP to mitigate potential adverse effects
  • Taking into account sensitive environmental features and habitat along the project route in planning and development
  • Engaging with Aboriginal and local communities to collect Traditional Land Use (TLU) information and Traditional Ecological Knowledge (TEK) to learn about potential concerns and issues
  • Ensuring that interruptions to traditional land use, including hunting and trapping, will only be temporarily affected by construction activities


The Right-of-Way
To safely construct and operate the pipeline, TransCanada will secure permanent access rights to strips of land called “rights-of-way.” Generally, a right-of-way is 10 to 25 metres in width, with an additional 10 to 20 metres set aside as a temporary workspace during construction.

When construction is complete and Energy East is operating, the permanent right-of-way will be maintained at a width of 10 to 25 metres to keep the area above the pipe clear of trees and branches. The width of the permanent right-of-way may vary depending on local requirements.

The pipeline will be buried under the ground, except at specific locations such as fenced valve sites and compression stations. While the surface of the right-of-way will be disturbed during construction, TransCanada will conserve topsoil when digging on agricultural land, so it may be returned afterwards.

Both during and after construction, TransCanada will also take measures to restrict the potential for invasive plants and weeds.
