Book Description
During the Remedial Investigation and Feasibility Study (RI/FS) phase of a CERCLA cleanup, it is possible to implement interim actions at a site ''to respond to an immediate site threat or take advantage of an opportunity to significantly reduce risk quickly.'' An interim action is a short term action that addresses threats to public health and safety and is generally followed by the RI/FS process to achieve complete long term protection of human health and the environment. Typically, an interim action is small in scope and can be implemented quickly to reduce risks, such as the addition of a security fence around a known or suspected hazard, or construction of a temporary cap to reduce run-on/run-off from a contaminant source. For more specialized situations, however, the possibility exists to apply the intent of the interim action guidance to a much larger project scope. The primary focus of this paper is the discussion of the interim action approach for streamlined remedial action and presentation of an example large-scale project utilizing this approach at the Fernald Environmental Management Project (FEMP).
