Green River Disposal Cell for low grade nuclear waste part of the former Green River Launch Complex

From the PDF link www.lm.doe.gov/Green_River/factsht_l.pdf

The cell was excavated to bedrock and was lined with 6 feet of low-permeability soil. Most of the contaminated materials are below grade. A clay-rich soil layer placed over the contaminated materials extends to the edge of the cell below grade and serves as a lowpermeability radon barrier. Above grade, the radon barrier is covered by a layer of rock (riprap) placed on granular bedding material. The cell design promotes rapid runoff of precipitation to minimize leachate. The walls around the edge of the disposal cell are lined with riprap and bedding material. A large riprap apron extends outward from the edge of the disposal cell for about 20 feet. Precipitation flows down the 20-percent side slopes into the surrounding rock apron. The disposal cell was located and designed to prevent or minimize erosion from storm water. The cell is located 75 feet above the Brown’s Wash floodplain. Existing gullies were filled and regraded during cell construction, and all disturbed grass surrounding the disposal cell were reseeded with native vegetation.
