Approval of Proposed Cleanup Remedies for Soil and Groundwater at Former Pure-Etch Company Site, Salinas, California

Approval of Proposed Cleanup Remedies for Soil and Groundwater at Former Pure-Etch Company Site, Salinas, California

The project consists of issuing a Negative Declaration for the proposed cleanup remedies for soil and groundwater at the former Pure-Etch Company site and to approve the Corrective Measures Study (CMS) Report. Pure-Etch has been subject to the Department of Toxic Substances Control's (DTSC) Corrective Action Consent Agreement for releases of gasoline contamination in soil and groundwater in a small area at the site beneath the closed-in-place underground storage tank. DTSC has identified the dual-phase extraction (DPE) as the preferred technology to properly remove the chemical constituents of gasoline contamination, such as benzene, tolune, ehtylbenzene and xylenes (BTEX), 1,2-dichloroethan, ethylene dibromide and naphthalene in the soil and groundwater. Removing the petroleum hydrocarbon contamination that is present in the vadose zone will remove the source of groundwater degradation via leaching of contaminants to the groundwater. To ensure that the site's land use is not changed, an administrative measure such as the Land Use Covenant, an annual site inspection and periodic groundwater monitoring will also be added to the remedy selected.
