Forestar Countryside Property Removal Action Workplan

Forestar Countryside Property Removal Action Workplan

The project involves approval of a Removal Action Workplan (RAW) for the Forestar Countryside Site (Site). The cleanup decision document, referred to as a Removal Action Workplan (RAW), summarized investigation activities and analysis for polychlorinated biphenyls (PCBs), metals, and organochlorine pesticides (OCPs). OCPs and arsenic are present at concentrations above action levels and a Removal Action is warranted. The RAW proposed excavation, transportation, and off-site disposal of contaminated soil over a period of 6 to 8 weeks. In addition, clean import soil may be used to backfill excavated areas. The following project-specific activities are intended to prevent exposure of contaminants to future site occupants and protect the environment. - Excavation - Approximately 13,500 cubic yards (950 truckloads) of contaminated soil will be excavated and loaded onto trucks for disposal. Standard equipment including backhoes, excavators, and front-end loaders and/or other appropriate equipment will be used to conduct excavation activities. Clean import soil may be used to backfill excavated areas (up to 950 additional truckloads assuming all excavated soil will be backfilled). Confirmation sampling will be conducted to ensure cleanup goals have been met. - Transportation and Off-Site Disposal - Based on the results of sample analysis, soils will be classified as either non-hazardous, California hazardous, or federal Resource Conservation and Recovery Act (RCRA) waste. Contaminated soil will be transported by truck to an approved off-site disposal facility. An approved truck route will be followed for trucks disposing contaminated soil.
