OA ARCAD I pesiyn&Caiuultancy farnaturaland built assets Privileged and Confidential Attorney Client Work Product Exhibit#347 February 13, 2024 Consulting and Support for 16888 McKinley Avenue, Lathrop, CA. The Scope of Work to be provided under this amendment includes professional services related to the SuperStore Industries facility located at 16888 McKinley Avenue, Lathrop, California (the"Site"). Based on Arcadis' understanding, C&S Wholesale Grocers, Inc.'s (CSWG's)and Greenbox Systems LLC. are considering acquiring of the Site. The scope of work provided below is focused on determining the presence or absence of a release associated several features located within the vicinity of the Truck Maintenance/Truck Wash Building. These features include: • Two underground storage tanks (USTs) containing diesel and associated dispensers. ■ Two 550-gallon USTs likely containing new and used oil. ■ Two oil/water separator units connected to the Truck Maintenance Building and Truck Wash Building. SCOPE OF WORK A brief summary of the proposed activities is outlined below. Task Estimated Cost Task 1 — Preliminary Activities Includes preparation of site-specific Health and Safety Plan,private utility clearance/One Call utility clearance, site mark-cut, site contact coordination, access agreement execution, and planning meetings. In addition, a Boring Permit Application is required to be completed and submitted to the San Joaquin County Health Department. The application approval process typically takes 1-2 weeks to obtain approval. The application requires payment of a fee which Arcadis will pay on behalf of CS WG/Greenbox Systems, LLC. Prior to initiation of subsurface work, a private utility clearance survey will be performed to identify the locations of subsurface utilities and features. The locations will be marked on the surface with spray-paint. The costs presented include estimated labor, subcontractor costs, boring permit application fee, and expenses. Task 2—Soil Boring Installation/Laboratory Analysis A series of 15 soil borings will be installed to evaluate subsurface conditions within the vicinity of the site features discussed above. The borings will be installed using a direct-push drilling unit. Soil samples will be collected into acetate liners. One soil sample is proposed to be collected for analysis from each boring. The sample selected for analysis will be determined in the field based on the results of field screening, visual/olfactory observations, or at a depth just above the observed water table. The final depth of each boring will not exceed 15 feet. Unused soils collected during the sampling process will be placed in a 55- gallon drum for characterization and offsite disposal. A previous investigation of the Site performed by others indicated that groundwater was potentially present at depths of 5-10 feet below ground surface(feet bgs).Assuming groundwater is present at these depths, four of the proposed borings will be completed as temporary monitoring wells for the purposes of collecting direct groundwater samples for analysis. A limited amount of purging will be performed prior to collection of the samples.All purge water generated during these activities will be placed in a 55-gallon drum for offsite disposal. Upon completion of direct groundwater sampling, the temporary well screen and riser will be removed.All boring locations will be backfilled with a slurry grout to the surface. The boring locations are required to be inspected by San Joaquin Health Department prior to closing the permit. Following inspection, the surface will be restored to match existing conditions(e.g., asphalt or concrete).
