One of the primary purposes for the Redevelopment Area and for UPC’s development project is the clean-up of the contamination that had built up over the past decades.  The combination of the former SPRR railyard operations and Schlage Lock’s 70-year manufacturing operations have left behind volatile organic compounds (VOC), arsenic, and other pollutants in the groundwater and soil.


UPC acquired the vacant railyard property in 1990. Through the  settlement of a decade-old, $100 million environmental lawsuit with the former owner of the Schlage Lock site, UPC became the owner of the Schlage Lock site in 2008.  Terms of the settlement include agreements with third parties that transferred liability for the soil and groundwater cleanup and insured against the possibility of unknown contaminants and unexpected costs. UPC is currently working with the California Department of Toxic Substances Control (DTSC) and Brownfield Partners to remediate the site. The Human Health Risk Assessment and a Remedial Action Plan (RAP), which defines the clean-up goals and process, was approved on November 16, 2009 following a public review and commenting period that ended on October 13, 2009.


Read a summary of the RAP in this RAP Fact Sheet (English). Or you can read it in Chinese or in Spanish.
