Construction is now well underway. While rain and severe storms in June and July – including a state record for rainfall in June –made work activities challenging, we are optimistic about achieving the planned December pipeline in-service date with restoration ongoing into 2016.

During major construction activity, the number of workers has increased and crews are spread out along the route from Pontiac to Patoka. Crews of 200-300 workers now assemble to perform work from stringing pipe, welding the pipe sections together, digging the trench, inspecting of the pipeline, lowering the new pipeline into the trench, backfilling the soils over the open trench, and other steps required to complete the project.

As of early September, construction activity is progressing as follows:

Spread 1 (Livingston County to Macon County) Crews have completed clearing on the nearly 93 miles of this stretch

of the route. The pipe is about 50 percent strung alongside the route and trenching is nearly half way complete. About 40 percent of the pipeline has been welded together and lowered into the trench.

Spread 2 (Macon County to Marion County) Crews have completed clearing and have about 75 percent of the pipe strung along the route. Trenching is also coming along with welding bringing the project to over 60 percent complete on the construction side.

One of the final steps of construction involves an integrity inspection of the pipeline using a process called hydrostatic testing. A diagram on page 2 illustrates the process. When we begin this testing, we will notify landowners and tenants of the schedule for the test and provide more information on what to expect. Some landowners will have an option to relocate for a day or so during the testing process when activities are

within an identified proximity to their home or business. Those property owners will be notified directly.

Senior Enbridge management toured the pipeline construction in July. All aspects of the process were reviewed including safety, environmental compliance and quality construction practices.

As we approach the home stretch of major construction, we appreciate the patience, cooperation and understanding that landowners and others in the project-area communities have extended to us. As always, please contact us with questions or comments.

Sincerely,

Scott Clark Project Director

We Build Safety in Every Step of Pipeline ConstructionPipeline construction is a multi-step process. These illustrations show the general construction process.

Soil is replaced and the right-of-way is restored per the terms of landowner agreements. Completing restoration is an important part of the process. Once the pipelines are placed into service, there continues to be ongoing communications and public awareness outreach along with a commitment to safe operations.

The pipeline is carefully set into the trench. Hydrostatic testing is performed prior to placing a new pipeline into service to further measure safe operating pressures.

Welders then weld the pipe sections together into a continuous pipeline. All welds are inspected for integrity. A trench for the pipeline is dug.

Pipe sections are then strung along the route. Materials are quality inspected from the factory and throughout the construction process.

Clearing the right-of-way is done at the onset of the process following prior surveying and landowner agreements. Topsoil is carefully separated and piled for replacement once construction is complete

Hydrostatic testing is performed prior to placing a new pipeline into service and sometimes as an additional integrity test on operating pipelines to further measure safe operating pressures using water pressurized above normal operating levels. Under controlled conditions, specially placed hoses pump non-toxic colored water into the pipeline in the section being tested to reach above operating levels. Hydrostatic testing pressures must be raised and held at that high level until integrity criteria are met to comply with specific, regulatory standards. While the process can take one to two weeks per segment to complete, the actual hydrostatic pressure test can typically be completed in less than a day. Landowners and tenants will be notified by letter prior to the testing to provide more detailed information and timing on the process in their area. Please watch your mail for notification. Signs will also be posted during the testing period along with additional public notification.

Hydrostatic testing is a safety and integrity process performed prior to a pipeline going into operation.
