Enbridge will pay $11 million to settle pipeline violations

Enbridge Energy, the owner and operator of the Line 3 pipeline project in northern Minnesota, will pay more than $11 million after investigations identified water quality violations and three aquifer breaches related to the pipeline’s construction, state regulators said recently. The Minnesota Pollution Control Agency (MPCA) and Department of Natural Resources (DNR) announced the results from investigations of water quality violations and aquifer breaches related to the construction project. Combined with the previous DNR actions, and in partnership with Fond du Lac Band of Lake Superior Chippewa, the investigations have resulted in more than $11 million in payments, environmental projects, and financial assurances from Enbridge, according to the state agencies.
