0 0 <br /> Comments: The "Subject Property" is indicated as significantly larger than the WDS area that has <br /> been investigated. Within the identified "Subject Property" boundary, the 1975 and 1982 historical <br /> aerial photographs have notation "waste pile" and "waste pile area," respectively corresponding to <br /> the glass waste disposal area. However, there are several other similarly appearing areas of <br /> surface disturbance that could also be interpreted to be the locations of waste disposal that <br /> appear related to and extend southwest of the area identified by AGE. It is not clear why "waste <br /> pile/waste pile area" was only noted at one area when there appear to be other areas similar in <br /> appearance and that appear related to waste disposal. It seems that based on these photographs, <br /> surface disturbance likely related to waste disposal, extended to at least two to three areas <br /> generally west/southwest of the area identified on the historical aerial photographs as "waste <br /> pile/waste pile areas." Similarly, subsequent aerial photographs identify the same "waste <br /> pile/waste pile area" identified on earlier photographs as "former pile area/former waste <br /> pile/former pile area stabilized," excluding areas to the west/southwest. It is not clear what"former <br /> pile area stabilized" means since available background information did not indicate that this area <br /> was "stabilized." A Google earth aerial photograph also included, did not have a date of the <br /> photograph and this photograph, as well as others around this time period indicate bluish-white- <br /> grey colored material, possibly colored glass material that appears stockpiled around the southern <br /> building area and within the "Subject Property" outline. This was not identified on the photographs <br /> or in any documents available for review. <br /> The LEA stated that it was decided that they need to be on site for the "excavation portion" and <br /> that they will need a Service Request form with funds for three hours of work and a work plan for <br /> the trenching, including safety plan, and a map of proposed trench locations and that they were <br /> keeping Wednesday available for the work. <br /> The email stated that AGE had prepared a site plan and work scope for the additional soil <br /> trenching on the parcel west of the subject site (17100 Murphy Parkway) and that they will deliver <br /> the check in the morning and to let them know if Wednesday was still available. The LEA <br /> responded the following day that Wednesday was available. <br /> --�z� ,b✓.otea_ , r . � ,u,. ,.,a,' � -� . , R ,u _, <br /> This email was provided by AGE and stated these were more LEA comments for the "PCLU[P]." <br /> The LEA provided the following comments: <br /> • AGE needs to include a landfill boundary map that will be used by the developer to present <br /> development plans (to show where buildings and improvements will be located with respect to <br /> disposal fill areas). <br /> • The landfill boundary map should include the location of investigation trenches and borings and <br /> appropriate labeling. The report should also include trench and boring field logs that support the <br /> sample location and waste extents map. <br /> Ninyo&Moore 1 500 E.Louise Avenue,Lathrop,San Joaquin County,California 1 104690095 1 August 11,2017 61 <br />
