This decision document changes a component of the selected remedial action for the Non-populated Areas Operable Unit of the Bunker Hill Superfund Site (Site). The ROD for this operable unit, signed on September 22, 1992 (PB93-964611), required treatment of all principal threat materials (PTMs) at the site. This Amendment to the ROD will require containment of all PTMs, except mercury, in a fully lined monocell rather than treatment followed by capping. Mercury contaminated materials will still be treated prior to disposal. This amended remedy will completely isolate the PTMs from the environment, including groundwater, thereby being protective of both human health and the environment. The containment design will also allow for potential future reprocessing of materials as technology develops. All other elements of the selected remedy set forth in the ROD are unchanged.
