| Abstract | The March 31, 1992 Record of Decision (ROD) (PB93-963801) called for, among other things, the installation of a cap with an impermeable barrier only on the top (flat) portion of the Ramapo Landfill. In addition, the ROD indicated that the landfill's side slopes would not require an impermeable barrier, unless further study concluded that incorporating an impermeable barrier would result in a significantly more effective remedy. The confirmatory studies called for in the ROD indicated that the exclusion of an impermeable barrier from the landfill cap on the side slopes would result in increased infiltration of rainfall through the cap. In addition, it was determined that either a thicker soil cover or an impermeable barrier would be needed on the side slope to provide adequate control of landfill gases. The impermeable barrier was found to be the less costly of the two options. |
