1.0 INTRODUCTION <br /> On behalf of Union Ice Limited Partnership (Union Ice), ICF Kaiser has prepared <br /> this remediation workplan for soil that was excavated from the former Union Ice facility <br /> at 425 North Union.Street, Stockton and is currently stockpiled at the Union Ice facility <br /> at 1320 Weber Street in Stockton California. This workplan is prepared in response to a <br /> request from the San Joaquin County Public Health Services Environmental Health <br /> t <br /> Division (PHS/EHD) in a letter dated .November 22, 1.995. <br /> As a basis for remediation planning, ICF Kaiser proposes the following soil <br /> cleanup goals: <br /> • Total petroleum hydrocarbons as oil (TPH-o) at 1,000 mg/kg; and <br /> • TPH as diesel (TPH-d) at 200 mg/kg. <br /> ICF Kaiser feels these soil cleanup goals will be sufficiently protective of the <br /> waters of the state and will not pose a significant toxicological threat to humans or the <br /> environment. These goals are in line with the screening-level cleanup goals that would <br /> be obtained following a leaching potential analysis, as presented in the 'Leaking <br /> Underground Fuel Tank Field Manual (State of California, 1989). <br /> 2.0 BACKGROUND <br /> ICF Kaiser sampled a soil stockpile at the Union Ice Facility located at 1320 West <br /> Weber Street in Stockton, California. Sampling was performed in accordance with the <br /> approved ICF workplan dated January 19, 1995. The stockpiled soil had been excavated <br /> from the former Union Ice Facility located at 425 North Union Street,=Stockton, aspart <br /> of a site remediation performed by WHF Consultants. The excavated hydrocarbon- <br /> affected soils resulted from leaky underground storage tanks at the North Union Street <br /> site. Approximately 2,400 cubic yards of this soil are stockpiled at the"West Weber <br />€- R41820A-1222950-1 <br /> soilrem.pin 1 <br /> k <br />
