November Keystone Crude Oil Spill Nearly Double Original Estimated Amount

A 2017 crude oil spill in South Dakota that came from TransCanada's Keystone pipeline was nearly double the original estimate, making the November incident the largest inland spill in the U.S. since 2010.

The Aberdeen American News reported that a spokesperson for TransCanada told the newspaper the incident caused 9,700 barrels of oil to leak in rural South Dakota on November 16. The original estimate was 5,000 barrels.

The pipeline was shut down immediately following the incident and was back in operation less than two weeks later.

TransCanada said the pipeline had been fully repaired and cleanup had been conducted.

The Keystone crude oil pipeline moves 590,000 barrels a day and links Alberta's oil fields to U.S. refineries.


TransCanada to Run Inspection Device in Keystone Pipeline After Spill

TransCanada plans to run an inspection device through its Keystone oil pipeline to check other segments of the pipe for similar characteristics to a section that ruptured in South Dakota in mid November.

The inspection is required of TransCanada by PHMSA, which issued a corrective order on the estimated 210,000-gallon oil spill. PHMSA said in its report that the leak was likely caused by pipeline and coating damaged from a weight that was installed on the pipeline during construction in 2008.

TransCanada said it would run the pipeline inspection gauge through its system within a 120-day period, as ordered by PHMSA.

The company will also submit a proposal to analyze available data on other weight locations for similarities with the faulty segment of pipe.

PHMSA Says Keystone Leak Likely Caused by Construction Damage in 2008

PHMSA issued a report Tuesday saying a recent Keystone oil pipeline leak was likely caused by damage during construction in 2008.

TransCanada's Keystone oil pipeline leaked 210,000 gallons of oil in South Dakota in mid November, and PHMSA officials are investigating the faulty section of the pipe. In a corrective action report, PHMSA wrote that a weight installed on the pipeline during construction in 2008 may have damaged the pipeline and coating.

Weights are sometimes placed on pipelines in areas where water could result in buoyancy concerns, according to PHMSA's report.

TransCanada has been working on the cleanup process at the spill site in Amherst, South Dakota. The state said it does not believe oil from the leak polluted any surface water bodies or drinking water systems.

TransCanada restarted the Keystone oil pipeline on Tuesday at reduced pressure.


Keystone Oil Pipeline to Resume Operations at Reduced Pressure

TransCanada's Keystone oil pipeline will resume operations Tuesday at reduced pressure after a mid-November spill that leaked 210,000 gallons of oil into South Dakota.

TransCanada's 590,000 barrels-per-day oil pipeline has been shut down for nearly two weeks following the leak in Amherst, South Dakota. The company has recovered about 20 percent of the spilled oil so far and continues cleanup operations onsite.

PHMSA approved the restart at reduced pressure and has been sent the faulty section of the pipeline for investigation.

The Keystone pipeline began operations in 2010 and moves oil from Alberta, Canada to Cushing, Oklahoma and Patoka, Illinois.

TransCanada Recovers More Than 44,000 Gallons of Crude at Keystone Pipeline Spill Site

TransCanada reports it has recovered 44,400 gallons of oil from the Keystone pipeline spill site that occurred in South Dakota earlier this month.

TransCanada shut down its 590,000 barrels-per-day Keystone pipeline on November 16 after it disclosed a 210,000 gallon spill on agricultural land in Amherst, South Dakota. A restart date has not yet been determined.

The company currently has about 170 personnel on site helping in cleanup activities.

The company said preliminary inspections of the damaged section of its Keystone pipeline will be done by the company and PHMSA staffs then sent to D.C. for an investigation by the National Transportation Safety Board's Metallurgical Laboratory.

TransCanada also said it conducted tests on a residential water well near the spill site and said all test results were normal.

The Keystone pipeline began operations in 2010 and transports crude from Canada to refineries in Illinois and Oklahoma.


TransCanada Begins Excavation Work after 210,000-Gallon Pipeline Oil Spill

TransCanada has begun excavation work at the location of a 210,000-gallon oil spill from its Keystone pipeline in South Dakota, said a state official on Monday.

The company is still trying to pinpoint exactly where the leak came from on its 590,000-barrels-per-day Keystone pipeline that moves Alberta, Canada oil sands to U.S. refineries.

Crews have started digging small excavations along the leak and have recovered some of the oil from the area.

Approximately 150 people are working around the clock to clean the area and investigate the cause of the spill, said TransCanada.

A restart date has not yet been established for the Keystone pipeline.

The spill occurred just a few days before TransCanada's Keystone XL expansion pipeline cleared a large hurdle by receiving permission from Nebraska to route through the state.


Keystone Crude Pipeline Leaks 210,000 Gallons in South Dakota

TransCanada's Keystone pipeline leaked an estimated 210,000 gallons of oil in South Dakota and was shut down by the company after it disclosed the spill on Thursday.

The spill occurred on agricultural land in northeastern South Dakota, but state officials do not believe the leak polluted any surface water or drinking water systems.

TransCanada detected a drop in pressure that resulted from the leak south of a pump station in Marshall County and activated emergency response procedures. The cause is currently being investigated.

The oil spill comes just days before Nebraska regulators are scheduled to announce their decision whether to approve the proposed Keystone XL route through their state. The Keystone XL would be an expansion that boosts the amount of oil TransCanada currently ships through the existing line called Keystone.

The Keystone pipeline began operations in 2010 and transports crude from Canada to refineries in Illinois and Oklahoma.

The Keystone XL project would move crude from Alberta, Canada to Nebraska, where it would connect with existing pipeline feeding refineries along the Gulf Coast.


Dakota Access Pipeline Leaked 84 Gallons of Oil; Tribe Pushes for Further Environmental Review

The Dakota Access Pipeline leaked 84 gallons, categorized as "a small operational spill," in South Dakota last month, and a Native American tribe is saying the spill shows that the pipeline needs further environmental review.

The spill occurred at a rural pump station in northeast South Dakota and was quickly cleaned up. It did not affect any waterways or cause any environmental harm, according to Brian Walsh, an environmental scientist with the state's Department of Environment and Natural Resources.

The agency had posted a report on the spill in its website's searchable database but did not take further steps to announce the spill to the public because it only releases news on spills if there is a threat to public health, a fishery, or a drinking water system.

Walsh said the spill does not come as a surprise and that it was "pretty small relative to a lot of other things [the agency] works on."

The Standing Rock Sioux Tribe, however, was not as forgiving of the news. The tribe believes the spills will continue and that the pipeline is a threat to the tribes' water supply and cultural sites. The tribe also argues that the line needs further environmental review.

A spokesperson for pipeline operator Energy Transfer Partners said the pipeline is safe and that the spill that occurred April 4 "stayed in the containment area as designed."

Energy Transfer Partner's Dakota Access Pipeline is expected to be fully operational by June 1.

Keystone XL Protestors Aim to Reverse Traverse Approval in South Dakota

Opponents of TransCanada's Keystone XL pipeline are seeking to reverse state regulators' decision to allow the pipeline to cross through South Dakota.

The South Dakota Public Utilities Commission's decision to approve its state portion of the Keystone XL, which it originally approved in 2010 before former President Barack Obama ultimately rejected the pipeline, is being challenged by several groups who believe the oil pipeline would contaminate water supplies and contribute to pollution.

Judge John Brown is set to rule whether or not to reverse the state's decision, but it has not been announced when that will be. He heard arguments Wednesday at Hughes County Courthouse in South Dakota during which more than 50 pipeline opponents gathered outside to protest.

South Dakota has already prepared for possible protests similar to the ones formed in North Dakota over the last several months against the Dakota Access Pipeline. As a precautionary measure, the state Governor Dennis Daugaard is pushing legislation that would make it a Class 1 misdemeanor for someone to stand in the highway as a way to stop traffic or to trespass in an emergency area.

South Dakota Section of Dakota Access Pipeline Nearly Complete

According to Energy Transfer Partners, work on the Dakota Access pipeline section in South Dakota is nearly complete.

In a report filed Friday to the South Dakota Public Utilities Commission, Energy Transfer stated that 100 percent of the South Dakota section of the four-state pipeline is underground. This includes underneath waterways such as the Big Sioux River.

The pump station in Redfield is 85 percent complete, according to the filed report, and the company is currently working on erosion control and testing.

The 272-mile section in South Dakota is part of a 1,170-mile oil pipeline that will travel through North Dakota, South Dakota, Iowa, and Illinois. It has spurred national controversy as thousands of protestors in North Dakota and other states have stood against its construction saying it would ruin waterways and destroy sacred sites.
