Blue Earth County gets the approval it needs to move forward with a proposed expansion of Ponderosa Sanitary Landfill. The Minnesota Pollution Control Agency has issued a 10-year solid waste permit for the facility. The MPCA found that the expansion, as proposed, has no potential for significant environmental effects. The proposal calls for an expansion of the facility by 16 acres. It will use a liner system to prevent seepage of waste into groundwater.
