February 24, 1999 Page 2 number and location of soil samples to be taken upon routine tank removal. Field and laboratory procedures are included as Attachment A. Our objectives in performing the scope of work are: 1. To remove existing underground facilities. 2. Address areas of soil impacted by 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), IT has prepared a Site-Specific Health and Safety Plan (Attachment B). The Site-Specific Health and Safety Plan will be reviewed by the field staff and contractors prior to beginning held operations at the site. Soil Sampling Activities During upcoming activities, ITwill be onsite to observe removal of the USTs and other, underground facilities, and to collect samples. When existing facilities are removed from the site, an IT representative will 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. Managerntnt of Excavated Soil and Limited Over-Excavation If hydrocarbon impacted soils are encountered, limited over-excavation may be performed. Over-excavation, if performed,will be limited to approximately 300 to 700 cubic yards of soil. The vertical ektent of the over-excavation will be based on the depth to groundwater(expected to be greater than 25 feet bgs) and the limits of the excavation equipment, which is approximately 25 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 an approved landfill. With the permission of SJCEHD, clean stockpiled soil may be reused as fill. Stockpiled soil not reused onsite will be covered with plastic sheeting and temporarily stored on site pending receipt of laboratory analytical reports. Soil will be removed •,r from the site and transported to an appropriate landfill facility. 911-011.1 A/W PLAN
