The entire 20-acre Project Area is considered a brownfield site due to existing contamination on the site. Until the closure in 1999, the Schlage Lock Factory (which occupied approximately 12 acres of land on the west portion along Bayshore Blvd) was one of the last remaining manufacturing sites in the city. Similarly, the Southern Pacific railyard (which comprised of approximately 6 acres on the eastern portion of the site) operated for many decades until the land was sold to UPC in 1990. These former operations involved the use of some industrial chemicals that have since been found to be hazardous materials.
In the early 1990s, soon after UPC had acquired the 6.36-acre Railyard parcel adjacent to the Schlage Lock Factory site, it was determined through ground water sampling that there was ground water contamination immediately southeast of the Schlage Lock Factory property. Environmental investigations that have been conducted continuously for more than 15 years have indicated that Volatile Organic Compounds (VOCs), primarily trichloroethylene (TCE) and perchloroethylene (PCE), are the main contaminants found in the groundwater within the site. Other contaminants present at the site include metals such as arsenic, chromium, cadmium, lead, and nickel, which are more typically associated with rail operations and found only in the soil. Soil removal and cleanup actions have been conducted at the Railyard site since 1996 and groundwater is sampled quarterly to monitor the movement and levels of chemicals in the groundwater. UPC has also installed a groundwater extraction and treatment facility, in compliance with the Regional Water Quality Control Board requirements. The groundwater extractions system installed by UPC in 1995 has kept the VOC contaminated ground water from flowing further into the Railyard site by containing the flow. It has also significantly reduced the contaminated plume of groundwater from what it was prior to the implementation of the extraction system to what it is, at this point, nearly a 25 percent reduction. . The groundwater extraction system has now been shut down in order to accommodate the remediation program being contemplated. Its continued use will be evaluated by the regulatory agencies as part of the Remedial Action Plan.
In May 2008, UPC settled a 10-year groundwater contamination lawsuit against Ingersoll-Rand (IR), the owner of the Schlage Lock factory site. The settlement ended in the transfer of the former Schlage Lock Factory property to UPC. The transfer occurred based on a Settlement Agreement that was entered into among the parties on May 30, 2008 in the settlement of litigation that was pending (No. C 05-03100 MJJ) in the United States District Court for the Northern District of California entitled, Universal Paragon Corporation et al v. Ingersoll-Rand Company, et al. The property transfer was accomplished based on a Conveyance Agreement, between IR and its related companies and UPC. The Conveyance Agreement required UPC to enter into a Guaranteed Fixed Price Remediation and Environmental Liability Transfer Agreement with a company that could assume all liability for the cleanup and accomplish the cleanup without an approved Remedial Action Plan. The Company acceptable to the parties for this task was Brownfield Partners. Brownfield Partners will be responsible for administering all sub contractors for demolition and site remediation. The cleanup standards will be set under a proposed Remedial Action Plan that will be the subject of public input and adoption by the Department of Toxic and Substance Control permitting residential use. The cleanup standards will result in an eventual clean-up of the ground water to drinking water standards.
