As part of the ongoing efforts to remove legacy contamination from the Richmond Field Station, a small area of soil in the vicinity of the former Forest Products Laboratory Wood Treatment Laboratory (WTL) was excavated for off-site disposal in early October 2007. Work completed under the Time Critical Removal Action (TCRA) is described in a public notice from the State of California Department of Toxic Substances Control. The final extent of the excavation has been approved by DTSC and the area will be backfilled with clean soil approved by DTSC.
Excavated soil, asphalt and concrete has been removed from the RFS to a DTSC approved disposal site. An implementation report on the TCRA is being written and will be made available at this site when complete.
