Site Inspection Removal Action Work Plan (Former Camp Bente SI / RAW)

Site Inspection Removal Action Work Plan (Former Camp Bente SI / RAW)

The actions to be taken at the Former Camp Beale are intended to investigate and characterize the subsurface environment for potential hazards posed by ordinance and explosives (OE) wastes. The proposed project is for a Site Investigation/Remedial Action (SI/RA) work plan to investigate the Volume 2 and 3 areas with a limited sampling methodology involving geophysical and intrusive investigations to characterize where munitions and explosives of concern (MEC) activities (target areas) occurred on the Former Camp Beale site. The geophysical investigation consists of one meter paths spaced 437 feet apart across properties within the site where access (Right-of-Entry) has been granted. Intrusive investigations or excavations of anomalies resulting from the geophysical work will consist of no more than 4 excavations per every 400 feet of the paths. This project proposes to conduct a SI/RA to collect and evaluate the data necessary to make informed decisions that will result in either (1) identify areas that pose minimal threat to public health or the environment and place these areas into a Risk Management Plan and process, or (2) determine the need for an effective and rapid initiation of the Remedial Investigation/Feasibility Study (RI/FS) for areas that pose a significant threat to public health or the environment. When the Site Investigation concluces, the United States (U.S.) Army Corps of Engineers, Sacramento District (CESPK), will develop a Site investigation report that: (1) documents the result of the investigation, (2) evaluates the findings of the MEC activities conducted in association with the proposed MEC alternatives, and (3) recommends further investigation under either a Remedial Investigation or Risk Management process. The Site Investigation report will include the findings of a MEC Safety Risk Assessment. The risk assessment will consider not only the current use of a particular parcel of land, but also the probable or planned future uses so that the activities under which human exposures to MEC are likely to occur can be reasonably predicted. CESPK, with local agency and stakeholder involvement, will determine the most appropriate alternatives based upon the type of MEC recovered, depth of MEC recovered, current and future land use of the parcel, and other appropriate criteria. This decision will be documented in the SI/RA report. The activities necessary to complete the investigation are expected to take approximately three months.
