Lanchester Landfill

Although merits of an EGC system existed, it was concluded that an EGC was not a suitable system for final cover at Lanchester, and examined the ClosureTurf with Agru geomembrane product. Based on the system research, ClosureTurf offered several advantages over a traditional EGC and over a traditional final cover system. Due to the lack of on-site soils available for cover, the use of ClosureTurf provides the opportunity for cost savings and eliminated the corresponding truck traffic that would have otherwise been required to haul in final cover soil from off-site sources. Post-closure maintenance of ClosureTurf will also be less costly than a traditional cover system, due to the elimination of grass, soil cover, and erosion potential. Detailed stormwater analyses were conducted to ensure that existing stormwater management features (e.g., channels, terraces, detention basins, etc.) will still function properly after installation of the ClosureTurf in the proposed areas.
