Raphael, Director <br /> Matthew Rodriquez 8800 Cal Center Drive Edmund Brown Jr. <br /> Secretary for Governor <br /> Environmental Protection Sacramento, California 95826 <br /> September 13, 2013 <br /> Mr. Fredric Clark <br /> Director Community Development Department <br /> City of Manteca <br /> 1001 West Center Street <br /> Manteca, California 95337 <br /> NOTICE OF HAZARDOUS SUBSTANCES PRESENT AT THE GORDON RESEARCH <br /> SITE; 1085 S UNION ROAD, MANTECA, SAN JOAQUIN COUNTY, CALIFORNIA <br /> Dear Mr. Clark: <br /> The Department of Toxic Substances Control (DTSC) provides this letter to notify the City of <br /> Manteca Community Development Department of the presence of hazardous substances <br /> at the property located at 1085 S Union Road, Manteca, California, assessor's parcel <br /> number(APN) 222-240-12 (the Site). Please place a copy of this letter in any files your <br /> office maintains for this property. <br /> In November 2007, DTSC's inspection of the property found hazardous substance spills, <br /> open hazardous substance containers and other conditions in violation of statutes and <br /> regulations. In 2007, DTSC issued an Imminent and Substantial Endangerment <br /> Determination and Order, Number 07/08-005, (Order) specifying the assessment and <br /> remedies necessary to address existing conditions at the Site. In response to the Order, the <br /> owner conducted some cleanup work between 2007 and 2009. However, in 2009, DTSC <br /> found the owner out of compliance with the Order for failure to complete the work. <br /> Therefore, through an emergency response action, DTSC completed the necessary <br /> removal actions in 2009. <br /> Between 2010 and 2012, DTSC conducted a Preliminary Endangerment Assessment (PEA) <br /> of the property to evaluate whether hazardous materials remained at the Site that may pose <br /> unacceptable human health and environmental risks. The PEA identified several areas on <br /> the property where hazardous substances exist. These hazardous substances were found <br /> to be arsenic, cadmium, lead, polychlorinated biphenyls (PCBs), total petroleum <br /> hydrocarbons (TPHs) and dioxin. The PEA determined that although the contaminants <br /> remain in top layers of surface soil in several specific areas of the Site, this remaining <br /> contamination does not pose a risk to groundwater or to off-Site human or environmental <br /> receptors. The PEA also determined that an immediate potential hazard to public health or <br /> the environment is low and an expedited response is not required. <br /> Printed on Recycled Paper <br />
