BISMARCK, N. D. – The Dakota Access pipeline and a feeder line leaked more than 100 litres of oil in North Dakota in separate incidents in March as a crew prepared the disputed $3.8 billion, a pipeline for the surgery.
Two barrels, or 84 gallons, spilled due to a leaking flange on a pipeline terminal in Watford City on March 3, according to the state, the Ministry of Health. A flange is the section connecting the two sections of the pipeline. The oil flow was immediately cut off and the leakage was recorded on the site. Contaminated snow and soil were removed. No people, animals or waterways were affected, according to the department of environment, health database.
The leak was on a line operated by the connecting of a sender on the Dakota Access pipeline, said Vicki Granado, spokeswoman for Texas-based Dakota Access developer Energy Transfer ners.
“They are responsible for the operation, maintenance, etc.,” she said.
A leak of a half barrel, or 20 litres, occurred March 5, in rural Mercer County, data from the federal Pipeline and Hazardous Materials Safety Administration show. Contaminated soil was removed, and no waterways were affected. There were no reports of injury to people or animals. The administration is part of the Ministry of Transport.
The online report says an above-ground valve failed due to a manufacturing defect, causing the leak. Upstream and downstream valves were closed to determine the cause of the leak. Later, all the other valves in the Dakota Access system were inspected and found to be OK.
The federal database appears to be no leaks along the pipeline in Iowa, or Illinois.
ETP maintains the pipeline is safe, but several tribes in the Dakota’s, including the Cheyenne River, Standing Rock, Yankton and Oglala Sioux for fear of damage to the environment and are fighting for the federal court, in the hope of convincing a judge to shut down the line.
The Dakota Access pipeline will move North Dakota oil 1,200 miles (1,930 km) through South Dakota and Iowa to a distribution point in Illinois. ETP plans to start commercial operations on 1 June.
North Dakota Environmental Health Chief Dave Glatt said the Ministry of Health lists such incidents in the online database, but usually not otherwise inform the public of oil is less than 150 barrels, unless the oil pollutes water.
The pipeline leaked 84 litres of oil in South Dakota on April 4. That spill at a rural pump station was quickly cleaned up and not threaten any waterways. It is the Ministry of the Environment and Natural Resources posted a report in the online database, but not in any other way informing the public. The policy is to be no press releases, leaks unless there is a danger to public health or water.
Tribal leaders and lawyers say that the leaks to strengthen their demands for more environmental review of the pipeline.
“We have always said: it is not a matter of, but when,” tribal lawyer Jan Hasselman said after the South Dakota lek. “Pipelines spill, and leak. It is just a fact.”
