Document Description
The Department of Toxic Substances Control (DTSC) approved the Removal Action Workplan (RAW) for the Lamont STEM Academy site (Site) to address the impacts of arsenic in soils at the Site. The cleanup decision document, referred to as a RAW, specified the removal action objectives, identified the contaminants of concerns (COCs), and described a remedial action proposed for the Site.
The approved remedy combines excavation with on-site capping of the impacted soil. The project activities consist of the following:
1. Preparation of two (2) cap areas (120’ x 165’ x 8.5’ deep & 200’ x 160’ x 8.5’ deep). These include a hardcourt area proposed for the eastern portion of the STEM school building area and a parking lot area proposed on the western portion of the STEM Academy Site.
2. Excavate approximately 12,363 cubic yards (CY) of impacted soil from identified locations. The majority of these excavations will be required as part of the geotechnical requirements for the foundation and paving areas at the Site.
3. Move the arsenic impacted soil from the stockpile and place them into the proposed cap areas as engineered fill.
4. Place a minimum 1.5’ buffer zone of clean soil on top of the arsenic impacted soil separated by a geotechnical fabric (weed cloth) which will serve as a marker.
5. Place impermeable surface covers (concrete and or asphalt) over arsenic impacted soil at the cap areas covered by clean soil. Maintain these cap areas over-time (30 years) to prevent surface exposure.
6. Place a Land Use Covenant (LUC) on the property to restrict future land use within the two cap areas. The LUC will be signed by the Lamont Elementary School District (District), the property owner and DTSC and recorded in Kern County Recorder’s Office.
