Santa Fe Road, San Joaquin <br /> County, Assessor Parcel Number 249-060-13. <br /> As background, the objective of the Work Plan is to further investigate only the 16.08- <br /> acre parcel referred to as the "Lynch IDS" in Figure 2 of the Work Plan to fill in data gaps <br /> with regards to the characterization of waste and condition of any existing cover. Some <br /> investigations and removal of wastes occurred in 2004, however, the work was not <br /> completed. As such, the full delineation of waste extents, waste characterization, and <br /> existing cover conditions on the property were not confirmed. <br /> To resolve these data gaps, the Work Plan proposes to use a track-mounted excavator to <br /> open a series of exploratory trenches at approximate locations shown on Figure 4 of the Work <br /> Plan. This trenching will be used to determine if buried waste is present and to visually <br /> determine the nature and thickness of existing cover. No samples are proposed to be <br /> collected and the excavated material will be returned to its place of origin and compacted with <br /> the excavator's bucket. <br /> The LEA has the following comments regarding the Work Plan: <br /> 1. Figure 4 shows the proposed exploratory trench locations which are based on <br /> information from a limited field investigation conducted in October 2002 (October <br /> 1868 E.
