MPCA seeks bonding and cash to address drinking-water contamination, C&D transitions and Superfund readiness

An assistant commissioner from the Minnesota Pollution Control Agency summarized three capital priorities for the MPCA at the March 10 committee hearing: a drinking-water contamination mitigation program focused on private wells near closed landfills; a new grant program to transition construction and demolition (C&D) operations to modern, less leaky facilities; and repurposing previously appropriated Superfund dollars to start an additional cleanup project.

The agency said the Blaine closed-landfill project (Johnson Brothers landfill) has roughly 20 homes with drinking-water exceedances of PFAS or 1,4-dioxin in an initial phase. MPCA proposed using bonding to build a water main and cash to connect homes as a more economical alternative to individual point-of-use treatment systems.

MPCA also asked for $5 million to create a sustainable C&D transition grant program that would help local governments close online C&D landfills, build transfer stations or recycling hubs, and install improved covers to limit leachate and contaminant migration. The agency said it is updating rules to require modern liners and leachate controls for future C&D sites.

On Superfund work, MPCA said it is nearly finished on several previously funded projects, needs to pause one (Duluth dump) because costs nearly doubled during design, and would like to move a ready Hibbing project forward; the agency requested permission to use existing appropriations to start an additional old gas-works cleanup instead of asking for new money.

When members raised Blooming Prairie contamination and asked who bears responsibility for closed landfills, MPCA explained the closed-landfill program moves state responsibility for selected facilities into an in-perpetuity state-care model and the agency prioritizes sites ready for work where immediate human-health protection is required.
