Document Type
NOE - Notice of Exemption
Document Description
The intent of the project is to mitigate impacted soils that exceed the proposed project-specific commercial cleanup level for arsenic in spoil at 25 mg/kg. The RAW proposes to manage the arsenic contaminated spoil on-Site by utilizing selective excavation and grading mechanisms, and construction of an asphalt pavement "cap". The estimated volume of contaminated soil proposed for on-Site encapsulation is ~1,550 cy. No contaminated soil will be transported off-site for disposal. DTSC will require an Operation and Maintenance (O&M) Agreement and Deed Restriction be placed on the Site property upon completion of the proposed RAW. The Raw will also require the import of clean fill material to complete the Site's proposed grading specifications.
