Document Description
The project includes excavating the shallow soil in the eastern portion of the Alley to an estimated depth of 2 feet below ground and implementing a new Land Use Covenant (LUC) for the newly investigated and capped area extending beyond the original cap that was subjected to the original LUC recorded on May 23, 1991. The California Department of Toxic Substances Control (DTSC) determined remedial actions were required to address elevated concentrations of polycyclic aromatic hydrocarbons (PAHs) at the former Southern California Gas Company/Olympic Base Site (Site). The Removal Action Workplan (RAW) from Southern California Gas Company (SoCalGas) addresses the PAHs in the soil at the Site as well as in the shallow soil in the alley way (Alley) adjacent to the southern border of the Site, belonging to the City of Los Angeles. The PAHs have migrated from the Site to the Alley are reported in surface soils of the eastern portion of the Alley at concentrations that pose an unacceptable risk to hypothetical future on-site residents.
