Mr. Robert McClellon Page 3 of 5 As you know, Mr. Palomino has been conducting site mitigation activities at APN 249-060-13 (Parcel 13). Mr. Palomino proposes conducting similar activities on Parcel 14 using the same protocols approved by EHD. 2.1 Excavate Surface and Buried Debris for Off -Site Disposal Mr. Palomino will excavate and coordinate disposal of surface and buried wastes located throughout most of the site. Debris previously identified in excavaton trenches T27, T29, and T30 will be removed to a permitted landfill. These areas are identified in the figure prepared by Ninyo & Moore for the CIWMB (Attachment A). The estimated soil and debris volumes are summarized in Table 3. As indicated in Table 3, it is estimated that up to approximately 1,300 cubic yards of debris will be excavated from these areas. The debris in these areas will be excavated using a Case 590E backhoe. General site grading will be accomplished using an International E295 scraper, a Caterpiller 9770 bulldozer, and a Caterpiller 613 scraper. All equipment will be operated by Mr. Peter Palomino, who is a trained heavy equipment operator and also has completed the 40 -hour Hazardous Waste Operations (HAZWOPER) training. No excavations are expected to exceed four feet in depth based upon site characterization conducted by CIWU B. The debris will be separated from native soil manually by Mr. Palomino or using a mechanical sifter, if necessary. The separated soil and debris will be stockpiled separately, pending ultimate destination. The separated debris will be loaded into trucks immediately after separation or temporarily stockpiled on site if less than a full load. Any stockpiled debris will be secured by temporary fencing or flagging or covered with clean, native soil. The debris will ultimately be transported to the Gilton Resource Recovery Transfer Station located at 800 S. McClure Road in Modesto, California for disposal. The volume of waste removed from the site will be tracked by cataloging the weigh tickets of each truck that exits the facility. Native soil separated from the excavated debris will be used on site for temporary cover where necessary. A significant volume of mixed soil and debris is located in the westernmost third of Parcel 14 along the western property boundary (the railroad berm) in the areas surrounding previous trench locations T31, T35, T36, T37, T40, T55, T56, and T59. As discussed with EHD, Mr. Palomino does not currently have the funds to mitigate the buried waste in this portion of the site. Mr. Palomino proposes to apply a 1 to 2 -foot soil cover in this portion of the site until funds become available to mitigate this portion at a later date. 2.2 Concrete Removal and Disposal Mr. Palomino intends to removed the concrete stockpiled in the northwest corner of the parcel. The concrete will be evaluated for the presence of rebar prior to removal. Any rebar will be G:\GROUNDZE\Palomino\wp_parce114.doc
