Lock Haven, PA: Landfill And Cap, American Color And Chemical Facility
This project involved the re-grading of potentially contaminated soils, installation of an engineered cover (cap) and improvements to the water management system at a former ink and dye manufacturing facility. Soils at the site were potentially contaminated with analine and other by-products of the industry.
Re-grading tasks included the relocation of wastes from three impoundments on the site. This included the placement of imported soils to the extent necessary to achieve the planned subgrade. Select fill material was placed in preparation for liner and geocomposite materials. The geotextiles placed at the site include a 40 mil LLDPE liner and a geonet composite material.
The improvements to the storm water management system were installed concurrently with the geotextile and liner material. These improvements consisted of high capacity perimeter drainage channels, three new tie-ins to the city storm sewer system and 400 linear feet of culvert and collection piping.
Work at the site was completed with the installation of a cover system over the liner materials. This system consists of 18 inches of cover soils and 6 inches of topsoil.
