NEW YORK, Nov 22 (Reuters) - U.S. pipeline regulatory officials will remain at the site of TransCanada Corp’s Keystone crude oil pipeline spill in South Dakota until the line has been restarted, the agency said on Wednesday.
Personnel will monitor the excavation and packaging of the damaged pipe section for testing, a spokesman for the Pipeline and Hazardous Materials Safety Administration said in an email.
The investigation over the spill last week is ongoing, he added. (Reporting by Catherine Ngai; Editing by Jeffrey Benkoe)
