Title

Approval of Remedial Action Plan for the Former Brown and Bryant, Shafter Site (APN #s 026-190-05 & 026-190-25)

Description

Approval of the Remedial Action Plan (RAP) for remediation of the former Brown and Bryant, Shafter facility (APN #s 026-190-05 & 026-190-25), hereafter referred to as the "Site". The RAP provides background information ont eh Site, the results of previous investigations, and remedial action alternatives evaluation. The alternatives evaluation lists the 5 remedial action alternatives considered int he previously approved Feasibility Study (FS) and the RAP presents a description of the preferred remedial alternative selected for the Site. The Proposed Action includes implementation of institutional control and land use controls in the form of deed restrictions/land use covenants on the land, continuation of the existing groundwater monitoring program, excavation and offsite disposal of shallow soils (0 to 6 feet) affected by pesticide and metals and in-situ soil vapor extraction (SVE) of deep soil (depths to 120 feet) affected by volatile organic compounds. Approximately 5,100 tons of pesticide and metal affected shallow soil will be excavated from several different locations throughout the site. The excavated soils will be disposed of offsite either at a Class I landfill or a Substitute D landfill depending on disposal profiling. Excavated areas will be backfilled with compacted clean soil once confirmation samples demonstrate that the remediations goals have been met. Risk based cleanup goals were developed by the Human and Ecological Risk Division (HERD) of the DTSC for practices relating to formulating, repackagein and application activities of pesticides, herbicides, fumigants and fertilizers.
