Superfund explanation of significant difference for the record of decision (EPA Region 7): Shaw Avenue Dump, Charles City, IA, March 24, 1992

Technical Report ·
OSTI ID:64807
EPA issued a Record of Decision (ROD) which presented the EPA-selected remedy for the first operable unit (OU1) at the Shaw Avenue Site in Charles City, Iowa (PB92-964309). The remedy selected in the ROD involved in situ fixation/stabilization of the chemical fill and surrounding contaminated soil, installation of a low permeability cap and ground water monitoring. Treatability testing conducted subsequent to the signing of the ROD indicated that in situ fixation/stabilization will not be adequate in treating the chemical fill and surrounding contaminated soil at the site. Therefore, this Explanation of Significant Differences (ESD) provides notice that the contingency remedy will be implemented and summarizes the basis for this change.
