Document Description
The Department of Toxic Substances Control (DTSC) has prepared the Corrective Measures Decision (CMD) for Building 5 Area Cleanup at the NP Oakley Facility. The CMD summarizes previous investigations and the remedy that was presented in the Corrective Measures Proposal (CMP), which was previously issued for public
comment. The CMD selected cleanup measures that are required to protect human health and the environment, and to address subsurface contamination in the Building 5 Area. The Building 5 Area was contaminated by NorthPoint’s release of partially treated groundwater to the Building 5 infiltration area.
DTSC’s selected remedy for the Building 5 Area includes the following elements:
1. Interim time-critical soil removal (already completed)
2. Long-Term Groundwater monitoring
3. Building 5 Sub-slab vapor intrusion mitigation system (VIMS)
4. Land Use Controls
