3M Co., which has spent $100 million on PFAS cleanup in Alabama, on Friday agreed to pay much more in a settlement with the state and the Environmental Protection Agency.
Alabama and EPA officials called it a landmark agreement, the "most far-reaching and significant enforcement action to date taken in regard to PFAS in the country."
Maplewood-based 3M's largest litigation settlement regarding PFAS was with the state of Minnesota in February 2018, when it agreed to pay for $850 million in cleanup actions, mostly in Washington County.
The Alabama agreement covers 3M's Decatur plant as well as other sites, some not yet identified, in the northwest part of the state.
3M said in a statement it was "fully committed" to fulfilling the consent decree obligations.
There is not a price tag attached to the consent decree. Lynn Battle, spokeswoman for the Alabama Department of Environmental Management, said it is too soon to determine the cost of the damage in dump sites and in the Tennessee River.
"It protects the public from both past and future contaminations, and puts Alabama ahead of the game in regulating these harmful compounds," Lance LeFleur, director of the environmental management department, said in a statement.
Separately, 3M already has agreed to a $35 million settlement with a water authority in Alabama.
