The Site has been contaminated with carcinogenic polynuclear aromatic hydrocarbons (PAHs), dioxins and lead in the soil; groundwater will not require remediation. The recommended remedial action detailed in the draft RAP is comprised of:
1. Ozonation treatment of 2,900 cubic yards of PAH contaminated soil for seven months.
2. Excavation will remove 500 cubic yards of lead and dioxin contaminated soil for off-site disposal, followed by backfill with clean soil.
3. Industrial land-use controls will restrict future activities and use of the site.
The DTSC is proposing to approve a draft Remedial Action Plan pursuant to authority granted under Chapter 6.8, Division 20, CA Health and Safety Code. The draft RAP was submitted by Flour Corporation, prior owner of the Site, to DTSC for approval under the revised Consent Order Docket No. HAS 88/89-027. The objective of the RAP is to remediate and remove contaminated soils on the Ecodyne Pond Site ("Site"). The remedy will protect human health and the environment in the vicinity of Site and allow continued industrial/commercial use.
