ekienvironment & water 1.0 INTRODUCTION EKI Environment & Water, Inc. ("EKI") has prepared this Soil Management Plan ("SMP") for the Former Pilkington North America Site ("PNA") at 500 East Louise Avenue in Lathrop, California ("Former PNA Site"; "Site") on behalf of ASP/RWM Properties, LLC, R & B Louise, LLC and R & B Delta, LLC. This SMP was prepared to comply with Water Code Section 13267 Order No. R5- 2019-0886 ("Order" — Appendix A), dated 12 April 2019, that was issued by the Central Valley Regional Water Quality Control Board ("RWQCB"). This SMP describes protocols to be implemented if previously unknown waste pits (e.g. the North and South Waste Cells on Parcel B) or other areas of obvious soil impacts with potentially hazardous materials (e.g. as observed in excavation for utility trench as documented in Attachment 3 Figure 16 to the Order (Appendix A)) are encountered during subsurface disturbance activities that may be conducted as part of ongoing and future Site redevelopment. 1.1 Background The Site currently 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 (Figure 1-1). The property includes one mostly - rectangular parcel (APN: 198-120-08) and a second irregularly shaped parcel on the northeast (APN 198-140-16) which total approximately 133 acres. The Site is located adjacent to a mixed residential, commercial and industrial area of the City of Lathrop, San Joaquin County, California. The Site is bordered to the west by a vacant field and a McDonalds restaurant, to the south by the former San Joaquin County Cogeneration Power Plant (Cogen) facility and a recently completed 870,000 square -foot ("sf") warehouse for commercial and light industrial purposes, and to the east by the former Occidental Chemical Company (Oxy Chem) and current JR Simplot Company (JR Simplot) sites (Figure 1-2). The Former PNA facility at the Site includes a large structure formerly utilized for glass manufacturing and distribution, two smaller stand-alone metal warehouse buildings, a sanitation plant, stormwater reservoir, sprayfields and asphalt parking areas (Figure 1-2). Glass manufacturing operations ceased in 2014 after over 50 years of operation. A furnace, furnace stack, conveyance machinery, above ground storage tank, and other facilities associated with the manufacturing process have been demolished pursuant to permits from the City of Lathrop. The Site is principally occupied by a Kraft Heinz distribution center (Figure 1-2). The northeastern portion of the Site is generally vacant and undeveloped with the exception of a rail spur. The rail spur is located along the southern portion of the Site and then extends to the northeast corner of the Site.
