Dec. 8 (Bloomberg) -- TransCanada Corp. is conducting 10 digs on its Keystone pipeline after finding anomalies, according to a company spokesman.
Each dig will expose about 120 feet of pipe for visual inspection and measurement, Terry Cunha, a company spokesman, said in a telephone interview. Crude oil deliveries will not be affected, according to Cunha.
The excavation process has begun in South Dakota, Nebraska and Missouri, according to the spokesman. He didn’t know when the work is expected to be completed.
The anomalies are areas in the pipeline where inline inspections indicated the pipe may have expanded beyond limits stipulated by the Pipeline and Hazardous Materials Safety Administration, Damon Hill, a spokesman for the agency, said in an e-mail.
The pipeline will be measured and the results compared to those of the inline inspection, Hill said.
When complete, TransCanada’s Keystone pipeline project will run more than 3,800 miles (6,200 kilometers) and cost $12 billion, and move crude oil from western Canada to the U.S. Midwest and Gulf Coast.
The pipeline is being built in phases. The first leg, from Hardisty, Alberta, to Wood River and Patoka, Illinois, began service this year and has a throughput capacity of 435,000 barrels a day.
