Document Description
The proposed project includes DTSC's approval of a Remedial Action Plan (RAP) project (Project) under Chapter 6.8 of the Health and Safety Code. The RAP proposal will cap in-place the soil impacted principally by lead and polycyclic aromatic hydrocarbons discovered in the park from the former "Small Arms Fining Range". The surface cap would provide a permanent solution that reduces the accessibility and mobility of the impacted soils, and the threat to human health and the environment. The surface cap would be installed over remediation areas. The Project includes the following activities associated with removal of approximately 12,900 cubic yards (cu.yd) of contaminated soils and disposal of these soils in appropriate landfills, import of approximately 27,800 cu.yd. Of clean soil approximately 16,750 cu.yd. of aggregate base to be used for the capping process, installation of drainage system, removal of approximately 166 non-Heritage, non-protected trees, replacement of these trees with at least an equal number of native trees, installation of an irrigation system for the new trees, and installation of fencing around trees and areas where capping will not be implemented. The proposed Project also includes rough grading the top 18 inches of soil to destroy the existing burrowing animal network and to prevent future settlement of animals by installing a layer of steel hardware cloth beneath the capping base. Portions of the Project site with steep terrain will not be remediated and will be fenced off to restrict public access. An operations and Maintenance Plan is also included to maintain the cap and a land Use Covenant will be required to prevent unauthorized uses of the Site and to prevent disruption of the cap. The proposed Project includes paving of an expanded parking lot adjacent to the existing parking lot. The proposed Project does not include demolition or modification of existing Project site structures or construction of new facilities (other than the additional parking lot) at the Project site.
