The project involves approval of a Removal Action Workplan (RAW) for 8485 Washington Boulevard, Roseville, California (Site). DTSC is overseeing cleanup at the Site under a Voluntary Cleanup Agreement (HSA-FY18/19-034) with Symphony Dreams LLC. The purpose of the RAW is to reduce the potential risk to human health and the environment from the contaminant of concern (COC) which includes lead in soil.
As described and discussed in the RAW, the following removal activities are proposed by the project Proponent to address the COC at the Site:
• Implement the selected remedy for the Recess Self-Storage & Washington Crossing Flex Industrial which includes the excavation of lead from three areas within the Project site and transportation of the soils to an offsite landfill location;
• Remove soil using conventional grading and construction equipment and dust suppression, stockpiling, storm water best management practices, and perimeter air monitoring; and
• Excavate soil ranging from a depth of surface soil to approximately 2.5 feet below ground surface (the total volume of the impacted soils that expected to be removed is 415 cubic yards).
DTSC utilized information and analysis in the Recess Self-Storage and Washington Crossing Flex Industrial Mitigated Negative Declaration (MND) to support a final determination about the type of environmental document required to be prepared for the proposed Final Removal Action Workplan for 8485 Washington Boulevard, Roseville, California as provided by Sections 15162, 15163, and 15164 of the CEQA Guidelines. Specifically, the MND analyzed potential impacts related to contaminated soils in Section IX (Hazards and Hazardous Materials) and potential impacts related to grading and construction in Section III (Air Quality), Section IV (Biological Resources), Section V (Cultural Resources), Section VII (Geology and Soils), Section VIII (Greenhouse Gases), Section X (Hydrology and Water Quality), Section XIII (Noise), and Section XVII (Transportation/Traffic).
