Enbridge continues to work diligently to return the impacted section of Its East Tennessee Natural Gas (ETNG) pipeline to service. As part of the construction underway, Enbridge is working to test the new section of pipe and install temporary equipment to help clean the inside of the existing pipeline around the incident location. That temporary equipment will then need to be removed prior to the line retuning to service. In conjunction with the construction work, Enbridge is in close coordination with the U.S. Department of Transportation and the Pipeline and Hazardous Safety Administration (PHMSA), and they understand the need to return the line to service expeditiously.
We recognize the increased demand for natural gas during the winter heating season, and we are executing on a plan design to restore capacity through the impacted section of ETNG to approximately 300,000 dekatherms per day between December 30, 2018, and January 3, 2019, based on current projections. We continue to coordinate with our customers during this temporary outage and are keeping them informed.
