Tri-County Landfill Inc. has submitted a permit application for the construction and operation of a municipal waste landfill (Landfill) in Liberty and Pine Townships, Mercer County. Tri-County previously operated a landfill at this location that accepted waste between 1950 and 1990. It has been inactive since 1990. The permit will allow Tri-County to develop and operate new waste disposal areas within the 99-acre permit boundary of the old landfill. Waste in the unlined area of the old landfill would be excavated and relocated onto new lined disposal cells.
