This document presents an Explanation of Significant Difference (ESD) from the Record of Decision (ROD) for the Umatilla Depot Activity (UMDA) Explosives Washout Lagoons Soils Operable Unit issued September 25, 1992 (PB93-964610). This ESD documents the significant differences to the selected remedy outlined in the ROD. In summary, the significant difference from the selected remedy in the ROD is the utilization of the treated soil as the organic component in the re-vegetation of several designated sites on the installation rather than backfilling the former Explosive Washout Lagoons with the compost.
