amec'9 <br /> ' and other Earthmoving Activities, a Construction Notification Form will be submitted to the <br /> SJVAPCD at least 48 hours prior to commencing any earthmoving activity on Site. <br /> 5.2.5 Dewatering <br /> Based on data collected during previous on-site investigations, and on data collected from <br /> monitoring wells located at the adjacent Former TAOC Tracy Pump Station Property, <br /> groundwater at the Site occurs at approximately 9 to 14 feet bgs. Due to the anticipated <br /> shallow depth of the proposed excavation (anticipated to be 6 feet bgs, maximum of 10 feet <br /> bgs) groundwater is not expected to be encountered in the excavation. <br /> 5.2.6 Off-Site Soil Disposal <br /> ' AMEC estimates that up to a maximum of approximately 1,350 yd3 of PAH-impacted soil could <br /> be generated for off-site disposal. Excavated soil will be stockpiled on plastic sheeting and <br /> kept covered to prevent dust generation and runoff, while awaiting profiling and disposal. <br /> Waste soil will be sampled and analyzed according to SW-846 (U.S. EPA, 2007) and the <br /> disposal facility requirements for characterization purposes. <br /> These soils will be <br /> transported off Site by a California-state registered hazardous waste <br /> ' hauler. It is assumed that the excavated soil will be classified as a Class II waste and will be <br /> disposed of at the Forward Landfill in Stockton, California, approximately 25 miles from the <br /> Site, unless the waste profile sample analytical results indicate otherwise. Typical trucks can <br /> ' transport approximately 10 to 20 cubic yards of excavated soil. Based on the expected volume <br /> of soil to be generated it is anticipated that approximately 70 to 140 trucks may be necessary <br /> to remove soil from the Site. <br /> Trucks will be properly placarded and the appropriate paperwork will accompany all waste <br /> shipments. All trucks transporting soil, sand, or other loose material will be covered. A <br /> designated wheel-cleaning area will be set up on or adjacent to the Site to brush off truck <br /> wheels prior to leaving the Site. Trucks hauling waste will exit onto Forest Hills Drive and will <br /> take Tracy Boulevard north to East 11th St, then East 11th St. east to Interstate 5 - North. The <br /> proposed trucking route is shown on Figure 8. <br /> 6.0 PUBLIC NOTIFICATION <br /> Public participation activities will be conducted prior to remediation activities. At least 1 week <br /> prior to the commencement of excavation activities, a work notice will be distributed to <br /> residents within approximately 1 block of the Site, as well as any other interested party or <br /> t California Air Resource Board (CARB)specifies an ambient air quality standard of 50 lag/m3for <br /> particulate matter less than 10 micrometers in diameter(PM1o). <br /> ' AMEC Geomatrix Inc <br /> I:\Doc_Safe\6000s\6628.001\3000 REPORTS\Excavation Work Plan-8.12.08\1 Text,cover and slips\Text.doc 9 <br />
