INTRODUCTION At the request of the current property owners, ASP/RWM Properties LLC, R&B Louise LLC, and R&B Delta LLC, AdvancedGeo, Inc. (AGI) has prepared this Site Investigation Report — Trench 29 Area for the property located at 500 East Louise Avenue, Lathrop, California (herein referred to as subject property, site, or Parcel A). The scope of work included the advancement of fifteen (15) soil borings to determine whether buried wastes are present in the location of T-29 and to identify and define the waste if necessary. Only pieces of trace glass cullet were observed during the investigation. Soil samples were collected beneath the pieces of trace glass cullet when observed in the borings during drilling. Field work was performed as outlined in the AGI -prepared Site Investigation Work Plan — Trench 29 Area (Work Plan), dated 07 June 2022. The work plans was approved by Central Valley Regional Water Quality Control Board (CVRWQCB) letter, dated 09 January 2023 (Appendix A). The location of the site is illustrated in Figure 1; soil boring locations and the T-29 area are illustrated in Figure 2; and historical trench locations are depicted in Figure 3. An Investigation Trenching Log summarizing details and information from the 2017 trenching investigation is provided in Appendix B. Extensive background information on the former Pilkington North America, Inc. Lathrop Facility Parcels A and B (Former PNA Facility) were provided in the Clean Closure Plan dated 20 June 2018, Site Assessment Summary Report — Final dated 21 June 2018, and Addendum to the Request for Exemption to Implement Construction Controls dated 12 July 2018. 2.0. BACKGROUND AND SITE INFORMATION Based on previous investigations and site history, the current property owner and AGI seriously questioned whether there was adequate data or information to suspect the presence of buried wastes or waste pits in the location of T-29. The area at and surrounding T-29 has been surfaced with asphalt and developed into a parking lot. Based on the industrial use of the property and the surface cap at T-29, it would appear the work was directed out of an abundance of caution. However, the property owner was willing to perform the investigation to satisfy the concerns of the CVRWQCB and the San Joaquin County Environmental Health Department (EHD). The subject property (Parcel A) has a physical address of 500 East Louise Avenue, Lathrop, California, and is located on the south side of East Louise Avenue approximately 400 feet east of the intersection of East Louise Avenue and Harlan Road. The property includes one parcel totaling approximately 59.44 acres (APN: 198-120-120) and is located within an industrial area of the city of Lathrop, San Joaquin County, California.
