1.0 INTRODUCTION On behalf of Union Ice Limited Partnership (Union Ice), ICF Kaiser has prepared this revised remediation workplan for soil that was excavated from the former Union Ice facility at 425 North Union Street, Stockton and is currently stockpiled at the Union Ice facility at 1320 Weber Street in Stockton California. ICF Kaiser prepared a soil remediation workplan dated December 22, 1995 for the disposal of approximately 150 cubic yards of hydrocarbon-affected soils. The workplan was prepared in response to a request from the San Joaquin County Public Health Services Environmental Health C Division (PHS/EHD) in a letter dated November 22, 1995. The soil volume in the December 1995 workplan was based upon a proposed cleanup level of 200 mg/kg for total petroleum hydrocarbons as diesel. PHS/EHD responded in a letter dated December 29, 1995, that a 200 mg/kg cleanup level would not be approved but that a �r 100 mg/kg clean up level would. This revised workplan presents the methods that will be used to remediate the stockpiled soil to the following soil cleanup goals: • Total petroleum hydrocarbons as oil (TPH-o) at 1,000 mg%kg; and • TPH as diesel (TPH-d) at 100 mg/kg. I ICF Kaiser feels these soil cleanup goals will be sufficiently protective of the ` waters of the state and will not pose a significant toxicological threat to humans or the 4 environment. These goals-are in line with the screening-level cleanup goals that would be obtained following a Ieaching potential analysis, as presented in the Leaking Underground Fuel Tank Field Manual (State of California, 1989). R 2.0 BACKGROUND ICF Kaiser sampled a soil stockpile at the Union Ice Facility located at 1320 West Weber Street in. Stockton, California. Sampling was performed in accordance with the approved ICF workplan dated January 19, 1995. The stockpiled soil had been excavated from the former Union Ice Facility located at 425 North Union Street, Stockton, as part R4182OA-0102460-1 soilremlpin 1
