Line 3 Replacement ProjectReturn to project
The Project route, facility design, and construction procedures have been designed to minimize impacts on the environment. Environmental impacts related to construction of the pipeline will primarily be related to temporary disturbance to land, wetlands, and waterbodies. Environmental impacts related to operations of the pipeline will primarily be related to maintenance repairs and mowing activities.
In 2014, Enbridge started working with federal, state, and local regulatory agencies to design Project plans and permit conditions to minimize impacts to the environment. Enbridge has already committed to a variety of resource-specific mitigation measures, which are detailed in Section 7 of the Route Permit. Enbridge will retain environmental inspectors (EIs) during Project construction who will be responsible for understanding all regulatory requirements and permit conditions, and ensuring that contractors abide by these conditions. The Project will also be supervised by third-party environmental monitors who will report any concerns directly to appropriate agencies.
- Although much of the pipeline will be routed along existing Enbridge or other utility right-of-way, new rights-of-way will be required.
- Extensive environmental surveys and field studies will be conducted to evaluate:
- wetlands and water bodies,
- threatened and endangered species habitats, and
- archaeological/cultural resources.
- Environmental management practices during construction will minimize short-term disruption and long-term impacts to land.
- Construction, safety, and environmental inspectors will be present during construction to monitor compliance with specifications, permits, and landowner agreements.
- Enbridge will develop and implement project-specific environmental protection plans, as required for the regulatory approval.
- Enbridge will restore land, as near as is practicable, to its pre-construction condition.
- Landowners will be notified prior to access or work on their property.
- During construction Enbridge will use modern land restoration techniques to prevent soil erosion, protect agricultural topsoil, repair agricultural drain tiles and irrigation systems, and alleviate soil compaction.
- A Project right-of-way representative will contact landowners to confirm restoration was completed and/or that compensation was handled according to agreements with Enbridge.
