DNR Accuses Enbridge of Numerous Violations During Line 5 Construction
The Wisconsin DNR issued a Notice of Violation against Enbridge for alleged environmental law violations during Line 5 pipeline construction. The DNR cited a 'persistent pattern of non-compliance' with state laws. Clean Wisconsin, involved in a legal case against the project, called for enforcement action. Enbridge has previously paid fines for violations in Wisconsin, including $275,000 for a 2019 spill and $1.1 million for 2008 construction violations.
