MAINTENANCE ACTIVITES CLOSED LANDFILL 13 FORT BENNING, GEORGIA DESCRIPTION OF SERVICES TASK 1 - Maintenance Activities: Background Information. Closed Landfill 13 was a sanitary landfill used for disposal of all wastes generated on Fort Benning. The facility was active between 1965 and 1983. The site covers approximately 60 acres of actual fill material. The fill zones generally lie astride and along the natural ridge at the site, with some wastes spilling over the slopes. The site has been capped with a Resource Conservation and Recovery Act (RCRA) Subtitle C approved cap. The cap consists of a 24 inch thick layer of compacted soil over the wastes, an impermeable membrane liner (40 mil HDPE), a synthetic clay liner, supporting geonet and drainage materials, and a final cover of 24 inches of soil. The cap extends to the bottom of the slopes on all sides of the natural ridge. Side slopes vary from 3H: IV to IH: IV. The total area covered by the capping materials is approximately 65 acres. The site is surrounded on all sides by chain-link fencing. The total fenced area of the site is approximately 90 acres. The site has numerous methane vents, groundwater monitoring wells, surface water collectors, drains, drain cleanouts, and drainage ditches. All drainage ditches are lined with stone riprap along the slopes of the landfill, for erosion prevention. Storm flow catchment basins exist on the southeast, southwest, and northern sides of the site, outside the cap but within the fenced area. The entire site is grassed, except for existing, ongoing erosion at several locations. Re-seeding/re-grassing repairs have been instituted under other contracts for this site.
