Line 3 Replacement Program

On behalf of Enbridge Pipelines Inc. (Enbridge), I am writing to provide you with information about our Line 3 Replacement Program (L3RP). Enbridge is proposing to replace the majority of Line 3 pipeline starting at Hardisty Terminal located near Hardisty, Alberta to Gretna Station located near Gretna, Manitoba. Subject to regulatory approvals, once the new pipeline is constructed and brought into service, the replaced pipeline would be permanently removed from operation. The National Energy Board (NEB) term for this is ‘decommissioned’. The L3RP will mean a safer, more efficient and more reliable pipeline.

Enbridge is committed to safe and responsible energy delivery. We strive to ensure our projects and operations are undertaken in a manner that minimize potential for adverse environmental effects and comply with environmental and regulatory requirements. Enbridge believes our approach to the L3RP will minimize disturbances to farmlands and reduce the potential for soil stability issues

This letter indicates that your land is located in an area where the existing Line 3 is proposed to be decommissioned. Most of the pipeline will remain in place; however, you may experience decommissioning activities such as segmentation of the pipeline and/or removal of above ground facilities. Enbridge is currently completing a detailed environmental assessment to determine appropriate locations for decommissioning activities. Our land agents will be contacting those landowners whose land will be directly affected by decommissioning actives in the coming months.

Line 3 Replacement Program overview Line 3 is a 34-inch-diameter, 1,600-kilometre pipeline between Edmonton, Alberta and Superior, . In service since 1968, Line 3 shares a right-of-way with up to five active pipelines along this route, all of which make up Enbridge’s Mainline system.

We anticipate submitting the application to the NEB in the fall of 2014. Depending upon the timing of regulatory approvals, the replacement pipeline could be in service in the second half of 2017.

The decommissioning activities will begin on the existing Line 3 in approximately mid-2018 once the Line 3 Replacement Pipeline is in-service. Decommissioning activities are anticipated to be completed in 12 to 18 months.

We will keep individual landowners and other stakeholders updated on the specific timeline in their area as we move through the planning and regulatory process.

Enbridge recently filed the L3RP Project Description with the NEB. The Project Description provides an overview of the entire project. It is a public document and can be downloaded from the NEB website www.neb-one.gc.ca and/or Enbridge’s website www.enbridge.com/Line3ReplacementProgram. Detailed information regarding decommissioning can be found on pages 23 – 29 of the Project Description.

How is a pipeline decommissioned? Several steps would be undertaken to manage the decommissioning process safely and responsibly, including: 1. Removing the oil from the pipeline by launching an internal device called a Pipeline Inspection Gauge (or ‘pig’). Using this method, the vast majority of the crude oil is removed from the pipeline. 2. Flushing the pipeline with cleaning agents and cleaning devices (scraper pig) to ensure the crude oil is completely removed. 3. Physically disconnecting the pipeline that will be decommissioned from any operating facilities. 4. Cutting and capping the pipe at certain locations as required. 5. Continuing the same ground monitoring program in place for active pipelines including: cathodic protection, pipeline patrol, pipeline signs, depth of cover surveys and One Call/Click Before you Dig Programs.

Why leave the pipeline in place? • Avoids major construction activities and disturbance to farmlands, neighbourhoods, roadways, wetlands and green spaces. • Reduces the risk of soil stability issues that could compromise the integrity of operating pipelines that share the right-of-way. • Subject to ordinary restrictions, farming and agricultural-related activities can continue on the pipeline right-of- way.

Who is responsible for the decommissioned pipeline? Enbridge is responsible for all of their pipelines whether they are in operation or decommissioned. Enbridge will be responsible for addressing any issue that may arise from the decommissioned pipeline.

We began consulting with landowners and communities along our existing pipeline right-of-way. Now, we are expanding the scope of the Program to include replacement of the majority of the Line 3 pipeline; as such, we have transitioned from the Line 3 Segment Replacement Program to the Line 3 Replacement Program.

WHY ARE WE REPLACING THE MAJORITY OF LINE 3? Line 3 will become a safer, more efficient, and more reliable pipeline. • Line 3 currently operates under a series of pressure restrictions, which limit its capacity. The replacement will allow us to restore capacity on our original Line 3 and to ship a variety of crude oil products for our customers. • Replacing Line 3 is the most efficient way to maintain and improve its reliability while meeting the requirements of our shippers. Once Line 3 is replaced with new pipeline and facilities, it will have no pipeline integrity-related pressure restrictions.

Enbridge is responsible for its pipelines, DECOMMISSIONING whether or not those pipelines are actively operating, as well as the costs related to PIPE—THE FACTS ongoing maintenance. The line will be kept in place and Enbridge is responsible for it in perpetuity. For every project, we strive to select the course of action that will have the least impact on you, your land, your community, and the environment. By leaving the decommissioned pipeline in place, we avoid added disturbance that would result from another round of construction caused by excavating and removing the existing line.

LEAVING THE DECOMMISSIONED PIPE IN PLACE You may wonder why we are leaving the decommissioned sections of pipeline in the ground. There are several reasons to leave the pipe in place: • Removing replaced sections of pipe entails major construction activities and disturbance to farmlands, neighbourhoods, roadways, wetlands, and green spaces, which we strive to avoid when possible. By leaving the pipeline in place, there will be no visible above-ground changes along the right-of-way, and farming and agriculture-related activities can continue on the pipeline right-of-way. • The heavy equipment needed to excavate and remove the buried pipeline segment must stay far enough away from active lines in order to maintain safe pipeline operation and construction. Currently, there are up to five active lines running adjacent to Line 3. • Finally, removing Line 3 could create soil stability issues and compromise the integrity of the other pipelines that share the right-of-way with Line 3. Our ongoing pipeline integrity maintenance program helps to identify pipeline segments potentially in need of maintenance or replacement. Using high-tech internal pipeline inspection devices is a crucial part of our comprehensive pipeline integrity maintenance program. Each device is The Enbridge Mainline consists of up to six separate pipelines of different diameters running parallel along the right-of way. designed to detect early signs of corrosion, dents, cracks, or other features.

PIPELINE Decommissioning

‘Decommissioning’ refers to the permanent cessation of What’s the difference between operation such that the cessation does not result in the decommissioned and abandoned? discontinuance of service to end users. These are regulatory terms used by the NEB. Decommissioning refers An example of this would be taking one of the pipelines in our to the permanent cessation of operation such that the cessation does right-of-way out of operation between Edmonton and Hardisty not result in the discontinuance of service to end users. while still providing the same level of service through another new, or other existing pipelines in the same right-of-way. To help illustrate, consider this simple analogy: decommissioning is roughly similar to closing down one of four lanes on a highway Although operation of a single pipeline has permanently ceased, connecting cities. The remaining lanes remain open and still the same level service is still being provided to the end point allow existing cars to travel between the cities. through our other pipelines. Abandonment means to the permanently cease operation such that the cessation results in the discontinuance of service. In How is a pipeline decommissioned? this case the operation of the pipeline permanently ceases and service comes to an end. In the analogy above, abandonment Once the National Energy Board (NEB) approves a decommission would mean a permanent closing down of all of the lanes of traffic. application, the general process of decommissioning a pipeline involves these steps: 1.

Since the decommissioned pipeline will not be removed, there will be no visible above-ground changes along the right-of-way. Subject to ordinary restrictions, farming and agricultural-related activities can continue on the pipeline right-of-way. 2. Avoiding the use of heavy equipment needed to excavate and remove the buried pipeline reduces risk to maintaining safe pipeline operation of other lines that share the right-of-way. 3. Finally, leaving a pipeline in place reduces the risk of soil stability issues that could compromise the integrity of operating pipelines that share the right-of-way.
