July 13, 2021
DULUTH – The Minnesota Pollution Control Agency is investigating a drilling fluid spill that occurred on the Willow River in Aitkin County at one of Enbridge's construction sites for its new Line 3 oil pipeline.
Drilling was halted after the nontoxic spill was discovered early July 6 and "containment and cleanup activities were started," MPCA spokeswoman Cori Rude-Young said Monday.
"The MPCA has been in regular communication with the on-site, independent environmental monitors and Enbridge Energy, and we have inspected the site cleanup," she said.
