BISMARCK, N.D. (AP) — Canadian crude oil is once again moving through a pipeline nearly two weeks after the line leaked an estimated 383,000 gallons of oil in North Dakota.

Calgary, Alberta-based TC Energy, formerly known as TransCanada, said in a statement that the Keystone pipeline “returned to service” Sunday after the approval of a repair and restart plan by the U.S. Pipeline and Hazardous Materials Safety Administration.

The company said it is still investigating the cause of the leak it reported on Oct. 29. That disaster affected about 22,500 square feet of land near Edinburg, in northeastern North Dakota.

“We will operate the pipeline at a reduced pressure with a gradual increase in the volume of crude oil moving through the system,” the company’s statement said.

The pipeline is designed to carry about 23 million gallons daily.

The agency ordered the company last week to keep the pipeline shut down until it had taken corrective actions such as sending a damaged part of the pipe to an independent laboratory for testing.

The North Dakota environmental scientist Bill Suess said on Monday that an affected section of the 30-inch underground steel pipeline was dug up and replaced “over the weekend.”

Suess said cleanup crews remained at the site on Monday. Some wetlands were affected, but not any sources of drinking water, he said.

TC Energy has said about 200 people were at the site working around the clock to clean up the spill. The company said about 285,600 gallons of crude oil have been recovered.

Crude oil began flowing through the $5.2 billion pipeline in 2010. The line is part of a system that also is to include the proposed $8 billion Keystone XL pipeline designed to take oil from western Canada to terminals on the Gulf Coast.

The proposed Keystone XL pipeline has drawn opposition from people who fear it will harm the environment.

The recent North Dakota spill also comes as the owner of the Dakota Access pipeline seeks to double the capacity of the line to as much as 1.1 million barrels a day. Texas-based Energy Transfer’s pipeline has been moving North Dakota oil to a shipping point in Illinois since 2017.

Before its completion, the pipeline led to massive protests near the Standing Rock Indian Reservation.

A hearing on the Dakota Access expansion is scheduled for Wednesday in North Dakota.
