The newly published investigation report will be buried in 2019 in Keystone XL Pipeline in Walsh County – Grand Forks Herald

Grand Forks – A fatigue rupture was probably the result of a defective pipe of the cause of a great crude oil pollution in Walsh County in 2019, as can be seen from an investigation report published by the US pipeline and Hazardous Materials Safety Administration.

Many details about the cause of October 29, 2019, Keystone XL pipeline break is unknown to the public because the 183-page report is greatly reduced. TC Energy, the Canadian former operator of the pipeline, has reduced the report on the protection of business secrets and information that, according to PhSMA, could reasonably jeopardize a person.

However, the document comes to the conclusion that part of the root problem has an “ineffective quality control” and inadequate inspections in Berg Steel Mill in Panama City, Florida, where the damaged part of the pipeline was produced.

The report also excludes a number of possible causes, including the intention to the pipeline.

The spill brought about 383,000 gallons of crude oil on about 5 hectares of wetlands outside of Edinburg, North Dakota, free and is one of the greatest crude oil fillings in the history of the state. The renovation of the affected property was completed in spring 2020. At that time, Dave Glatt, director of North Dakota Department of Environmental Quality, praised the clean -up work of the company as some of the best and smoothest things that his agency had seen.

TC Energy finally reached an agreement with the NDDEQ and agreed to pay a fine of around 52,000 US dollars.

The investigation report – formally the cause of the cause failure – was written by RSI Pipeline Solutions, an Ohio -based consulting company. It is dated on April 1, 2020.

According to the report, the alarm of Edinburg and Niagra stumbled, shortly before 9:00 p.m. October 29, 2019, stumbled and a controller – an employee who monitors the pipeline systems – stopped the pumps. Rural pump stations in the region often have unexpected shutdowns, sometimes as often as several times a week, and for this reason there may have been a slight delay in the correction effect. However, within 5 seconds, the controller recognized that something was more serious and requested that the system be closed, the report said.

The report showed that the leak detection system, the reaction to the control room and the emergency reaction were all adequately responded to the release. It was found that there is an opportunity for additional controller training. It also suggested that pipeline operators with rural supply providers should work together in order to improve the reliability of services to pumping stations.

The Keystone XL pipeline, from which it was expected to promote crude oil from the Canadian province of Alberta to Nebraska, is no longer in operation. The construction of the pipeline was discontinued in 2021 after President Joe Biden revoked an important approval for the construction on US floor. Last month, President Donald Trump said that he wanted the pipeline “return to America,” said a Reuters report.

Last year TC Energy pronounced its oil pipeline business in a new company called South Bow Energy. A spokesman for South Bow announced Reuters that the Keystone XL company was “forwarded”.
