Scope of Work:
¨ The Landfill No. 6 project involved the closure and capping of the last RCRA hazardous waste landfill at GES’s Waterford, New York plant. The landfill was one of only two permitted hazardous waste landfills remaining in New YorkState and was subject to a high level of regulatory scrutiny.
¨ The scope of work included subgrade preparation, engineered cap construction (GCL and 40 mil LLDPE), gas vent installation, drainage controls, and installation of barrier soils over a 1.4 acre parcel at the top of the landfill. Due to the presence of hazardous waste, extra measures were taken to protect the waste from water intrusion and wind erosion during grading and cap construction.
