Document Description
The IMW was submitted on August 11, 2014 by The Source Group Inc (SGI) on behalf of NUMMI. The purpose of the IMW is to prevent or minimize exposures to chemicals of concern (COCs) from known contaminated source areas in soil and groundwater and prevent migration of COCs from source areas to underlying groundwater. The interim removal action proposed for the Site consists of the following activities: excavation and off-site disposal of approximately 14,585 cubic yards ("yd3") of lead, total petroleum hydrocarbon (TPH), benzene, toluene, ethylbenzene, and xylenes (BTEX), and naphthalene contaminated soil from two areas, the Former Fuel Dispenser Island and Former Tank Farm Area (hereinafter the "Project Area"); soil will be transported off-site to approved Class I or Class II Landfills; excavation area groundwater will be removed and treated using granular activated carbon prior to discharge under permit to the Union Sanitation District ("USD"), the local Publically Owned Treatment Works "POTW"); after completion of removal activities, excavation areas will be backfilled with approximately 3,167 yd3 clean crushed rock and 20,622 yd3 clean fill soil from local sources. After backfilling, concrete and asphalt barriers will be installed to return the surface of the Project Area to its current covered condition. Groundwater monitoring wells that are within the excavation footprint will be destroyed and reinstalled after the Project Area is restored. The project activities are expected to be completed in approximately 100 days.
