- Document Description
- The project is the approval of a Removal Action Workplan (RAW) by the Department of Toxic Substances Control (DTSC) pursuant to Health & Safety Code, chapter 6 8; chapter 6 5, etc as submitted on January 2, 2008, by ENVIRON International Corporation (ENVIRON). The RAW focuses on excavation and removal to mitigate soils impacted with excessive levels of lead, polychlorinated biphenyls (PCBs), specifically Arochlor 1260, and perchlorate in soil on Site. The purpose of the project is to mitigate impacted soils that exceed the project-specific human health risk criteria to minimize migration of and human exposure to the identified chemicals of concern (COCs). The estimated volume of impacted soils is 105 cubic yards or approximately seven (7) truckloads. The cleanup levels for these COCs are: Site-specific Risk-based Threshold Concentrations (RBTCs) of 150 milligrams per kilogram (mg/kg) lead, 221 micrograms per kilogram PCBs/Arochlor 1260, and 01 mg/kg perchlorate. Project activities will commence in early April of 2008 and are expected to take approximately 110 days to complete. Excavated soils will be transported using a licensed hauler to an appropriately licensed facility for disposal. Specific environmental safeguards and monitoring procedures that are enforceable and made a condition of project approval to ensure that impacts to the environment will be less than significant are included in an approved Excavation Plan, Engineering Evaluation/Cost Analysis, Health and Safety Plan, Quality Assurance Project Plan, Transportation Plan, and Air Monitoring and Dust Control Plan. In addition, in the event resources of biological, cultural, or historical resources specialist makes an assessment of the area and arrangements are made to protect or preserve any resources that are located. If human remains are discovered at the Sited, no further disturbance will occur in the location where the remains are found, and the County Coroner will be notified pursuant to Health and Safety Code section 7050 5. The Coroner will determine disposition within 48-hours (Public Resources Code, section 5097 98). An analysis of project activities upon existing environmental conditions indicates that implementation of environmental safeguards and monitoring procedures are enforceable and made a condition of project approval and will ensure that impacts to the environment will be less than significant. As a result, DTSC finds that the project is exempt from further environmental review under CEQA.
