Regulator Reports New Spills Along Line 3 Construction Route

ST. PAUL (AP) — Minnesota regulators say there have been more releases of drilling fluid along the Line 3 oil pipeline construction route than previously reported.

According to the Minnesota Pollution Control Agency, there were 28 releases at 12 river crossing locations from June 8 to Aug. 5.

In one instance, about 80 gallons of fluid entered the Willow River in Aitkin County.
The agency disclosed details about the releases in a letter to Democratic state lawmakers who requested the information.

Drilling fluid is made mostly of bentonite clay and water. It's not considered toxic, but can impact aquatic life.
