Current update

Crews continue to clean-up and remediate the impact area. So far, approximately 8,000 barrels of crude oil has been safely recovered. We will continue working until all the oil, which we continue to estimate at 9,120 barrels, has been removed and the site fully remediated.

We continue to work closely with the U.S. Pipeline and Hazardous Materials Safety Administration (PHMSA) and the North Dakota Department of Environmental Quality as we investigate the cause of the incident and analyze the impacted segment of removed pipe.

On Sunday, Nov. 10, the Keystone pipeline returned to service following the approval of its repair and restart plan by the U.S. Pipeline and Hazardous Materials Safety Administration (PHMSA).

We appreciate the cooperation and support from local officials, emergency response personnel and commissioners in Walsh County, as well as the landowner who has granted permission to access land for assessment, repair and clean-up activities. We also want to recognize the continued efforts of our crews, contractors and businesses in the community for their around-the-clock support, which allowed us to respond quickly and safely to this event.

Work continues to progress at the Edinburg incident site in North Dakota with about 200 round-the-clock personnel focused on clean-up and remediation activities.

To date, approximately 6,800 barrels of oil have been recovered. Preliminary work to expose and extract the damaged section of pipe has begun and we expect to have this complete, by the end of this week. The pipe will then be sent to a third-party laboratory, approved by the Pipeline and Hazardous Materials Safety Administration (PHMSA), for a full investigation.

We’re continuing to monitor air quality around the site and the surrounding area throughout clean-up, with no concerns.

Our engineers and PHMSA continue to evaluate the most appropriate restoration methods for the site.

Our on-site team is focused on responding to the release and has begun recovering oil, using specialized equipment. The approximate size of the impacted area is 2,500 yd2 or less than half the size of a football field.

We continue to inform regulatory agencies and local stakeholders of our progress. We have provided an initial estimate that 9,120 barrels of oil was released; approximately half the size of an Olympic-sized swimming pool.

Our crews remain focused on oil recovery as they plan to make repairs to the pipeline. We will provide updates as they become available.

Our crews will remain focused on oil recovery and then prepare to make repairs to the pipeline. We will provide updates as they become available.

Our emergency response team contained the impacted area and oil has not migrated beyond the immediately affected area of approximately 2,500 yd2. We do not have the exact volume released at this point.

We are establishing air quality, water and wildlife monitoring and will continue monitoring throughout the response. There have been no reported injuries or impacted wildlife.

We appreciate that there are questions about the cause of the release. We will not know specifics about the cause of the incident until we complete the investigation and the segment of the pipeline is analyzed by an independent metallurgical lab.

The safety of the public and environment are our top priorities and we will continue to provide updates as they become available.

Our TC Energy specialists from emergency management, engineering, environmental management and safety as well as contracted, nationally recognized experts are on site and will continue to work 24/7 to support response to the incident. 

We continue to provide State and Federal regulators such as Pipelines and Hazardous Materials Safety Administration (PHMSA), the North Dakota Department of Environmental Quality (NDEQ) and the National Response Center (NRC) with accurate and confirmed information and ensure they are fully aware of all of our response plans and activities.

We have been keeping our shippers and customers up to date and have communicated that the pipeline from Hardisty, Alberta to Cushing, Oklahoma and to Wood River/Patoka, Illinois is expected to remain shut down as we respond to this incident. This does not affect the Marketlink pipeline system, which uses the facilities of the southern leg of the Keystone system from Cushing to the Gulf Coast.

The safety of the public and environment are our top priorities and we will continue to provide updates as they become available.

A drop in pressure was detected by TC Energy’s operations control center at approximately 9:20 p.m. M.T. on October 29, 2019. We immediately began the process to shut down the pipeline, activated our emergency response procedures and dispatched our ground technicians to respond to the incident.

Frequently Asked Questions

No, the impacted area has not increased beyond the original containment effort established on the day of the incident which was approximately 4.8 acres. The initial estimate of 2500 square yards was based on the most prominently visible area. As noted in our October 31 update,  the initial size estimate was “roughly half a football field.”  That area was closest to the pipeline area itself.

The first goal was to eliminate the risk.

  • Upon detection of the incident, the pumps were shut down and valves were closed to isolate the pump station and surrounding segments of the pipeline. 
  • Crews and equipment were dispatched to the area, and steps were taken to ensure safety and security for personnel and residents.
  • On-site visual inspection confirmed that the safety systems on the pipeline were working.
  • State and Federal regulators were notified along with impacted landowners.


Please see TC Energy Incident Commander Virgil Pfennig explain our response

We will send the removed section of the damaged pipe to a metallurgical laboratory for testing. After the pipe is tested at the laboratory, an independent investigation into the root cause of the incident will be conducted by a third-party specialist acceptable to PHMSA.

The order has outlined several actions that we must undertake in order to safely return and operate the system following this incident. Some of those steps include ensuring the damaged section of pipe undergoes third-party metallurgical testing of the pipe; developing a remedial work plan and conducting a historical review of the pipeline, including construction records.

We will not speculate about the cause of the incident until we complete our investigation and the segment of the pipeline is thoroughly analyzed by the metallurgical lab. We want to ensure information is accurate and verifiable so we can learn from it and apply it to our pipeline integrity efforts.

The response and cleanup require a large number of heavy equipment, machinery and individuals and with safety as our top priority, we need to keep the area adjacent to the incident clear. Due to the extensive clean-up process we do not have a deadline to reopen the roads.

We will follow all applicable federal and state regulations in disposing of the contaminated soil. It will be transported to a facility that is certified to dispose of this type of waste.

Our environmental specialists have taken several steps to prevent wildlife from entering the contaminated area, including the use of flags that ward off birds and other creatures and mylar ribbons and tapes. We have had no reports or any indication that any wildlife has been harmed by this incident.
