' Tosco Marketing Company \ 2 Circle K Service Station 8671, Stockton, CA March 23, 1998 I 2. Address areas of soil saturated with hydrocarbons using limited over-excavation or other appropriate methods based on the levels encountered.. Site-Specific Health and Safety Plan As required by the Occupational Health and Safety Administration (OSHA) " Hazardous Waste Operations and Emergency Response" guidelines (29 CFR 1910. 120), and by California Occupational Health and Safety Administration (Cal-OSHA) " Hazardous Waste Operations and Emergency Response" guidelines (CCR Title 8, Section 5192), a Site-Specific Health and Safety Plan will be prepared for the site. The Health and Safety Plan will be reviewed by the field staff and contractors prior to beginning field operations at the site. I Soil Sampling Activities During upcoming activities, SECOR will be onsite to observe removal of the dispensers and other associated underground facilities, and to collect soil samples in accordance with SJCEHD requirements. The samples will be submitted under chain-of-custody documentation to a California State-certified analytical laboratory for analysis as described below. I Management of Excavated Soil and Limited Over-Excavation If soils saturated with hydrocarbons are encountered, limited over-excavation may be performed. Over-excavation, if performed, will be limited to approximately 50 to 200 cubic yards of soil. The area of possible over-excavation is shown as a dotted line on Figure 1 . The vertical extent of the over-excavation will be based on the limits of the excavation equipment, which is approximately 15 feet. Upon excavation, the soil will be stockpiled in segregated piles and covered with plastic sheeting at the site for sampling and later disposal. All stockpiled soil will be sampled at one four point composite for every 100 yards and subsequently hauled and disposed of at a approved landfill. With the permission of SJCEHD, clean stockpiled soil may be reused as fill. Stockpiled soil, covered with plastic sheeting, will be temporarily stored on the northern portion of the site. It should be noted that the Circle K Store onsite will remain open during the dispenser upgrade activities . To reduce potential hazard associated with the presence of stockpiled soil onsite generated from excavation activities, Tosco requests SJCEHD written approval to transport the soil to Forward Landfill' s holding area. Once analytical results of the stockpile sampling are received, the landfill will utilize the soil at their facility appropriately . 7G888-010-01/Wplan
