CCR Projects
Horsehead Landfill
Project Description
KEY provided a range of services at the Horsehead Landfill, located adjacent to the Shell cracker plant, in Pennsylvania. This Residual Waste Landfill, permitted by PADEP, was used by Horsehead Recycling to handle CCR and zinc smelter slag. KEY provided Quality Control (QC) oversight services during construction of the 12-acre Phase II work which required a single 6-inch thick clay liner. A leachate collection system consisting of perforated PVC piping was located within a smelter slag drainage layer. The surrounding perimeter berms were constructed from on-site soils. The project also required the construction of a landfill access road.
Activities Performed
Following PADEP approval of the plans and specifications, KEY prepared a Construction Quality Assurance Plan for landfill construction, provided full-time QC oversight, constructed a test pad for the clay liner, and prepared a Construction Certification Report.
