H3. RCRA Cap.

H3. RCRA Cap. Ten acres of black, high-density polyethylene form a Resource Conservation and Recovery Act (RCRA, 1976) cap to cover a mixed waste landfill at the Oak Ridge Reservation. The cap is designed to prevent gases from escaping, reduce erosion, and keep rainwater from leaching contaminants into groundwater. Installed in 1989, the cap is designed to last 15 to 20 years. Maintenance and monitoring will be required at least until 2019. Solid Waste Storage Area 6, Oak Ridge Reservation, Tennessee. 11 January 1994.
