Orange County Metal Processing, Inc, and Former PCA Metal Finishing Facility, Feasibility Study (FS) / Remedial Action Plan (RAP)

Orange County Metal Processing, Inc, and Former PCA Metal Finishing Facility, Feasibility Study (FS) / Remedial Action Plan (RAP)

The Department of Toxic Substances Control (DTSC) is considering approval of a Feasibility and Remedial Action Plan (FS/FAP) for the Orange County Metal Processing, Inc. (OCMP) property located at 1711 Kimberly Avenue and the adjoining Former PCA Metal Finishing (PCA Metal) property located at 1726 East Rosslynn Avenue in Fullerton, California (hereinafter the "Site", Attachment 1) pursuant to Chapter 6.8, Division 20, Sections 25323.1 and 25356.1 of the California Health & Safety Code, as submitted on February 6, 2015. Amec Foster Wheeler Environment and Infrastructure, Inc. (Amec Foster Wheeler) has prepared a draft FS/RAP on behalf of DTSC to evaluate potential remedial alternatives and present the FS/RAP to remediate chemicals of concern (COCs) in soil and groundwater at the Site. DTSC will be providing oversight for the implementation of the FS/RAP. The approximate 2.3-acre Site consists of two adjoining properties: the OCMP property which occupies the western portion of the Site and the former PCA Metal property which occupies the eastern portion of the Site. Both properties are owned by the PCA Industries LLC (PCA Industries) and have had similar business operations and metal handling histories. Both properties have contributed comingling releases to soil and groundwater. The purpose of the project is to remediate soil, soil vapor, and groundwater contaminated with COCs consisting of volatile organic compounds (VOCs; primarily tetrachloroethene [PCE] and trichloroethene [TCE]) and shallow soils contaminated with hexavalent chromium, cadmium, and cyanide at concentrations that exceed the project-specific Commercial/Industrial cleanup levels in order to minimize human exposure to the identified COCs. Implementation is expected to begin in June 2015 and is expected to take approximately 1 to 2 months for construction phase (soil excavation, well installation, etc.) to complete and one year for the remediation phase (soil vapor extraction and groundwater treatment) to complete. Upon completion of the RAP, a Land Use Covenant (LUC)/deed restrictions will be implemented to limit Site use to industrial /commercial uses and prohibit future Site use for residential, hospital, hospice, school, or daycare center use of the Site. IC's will be implemented while remediation is in progress until ultimate RAOs that would allow for unrestricted reuse of the Site are achieved. Governmental controls on the Site would include zoning restrictions (to limit future land-use), permit review, and well restriction of groundwater use restrictions. Prior to site certification, an Operations/Maintenance and Monitoring (OM&M) Plan, and LUC between the property owner and DTSC will be required to implement the OM&M activities for any future soils maintenance and groundwater work in accordance with an approved OM&M Plan under DTSC oversight.
