Cape Environmental Managemenk Inc. <br /> Health&Safety Plan <br /> existing underground storage tank(s) Approximate locations of fuel delivery lines from the <br /> USTs to the main building are shown on the site drawings. No tank vents, clean-outs, or <br /> sticking ports were observed. The area of the USTs consists of lawns and shrubbery <br /> landscaping. <br /> Underground obstructions in the immediate vicinity of the USTs include the UST fill pipe <br /> and fuel delivery lines, gas lines and electric lines. A buried telephone conduit is located <br /> approximately 30 feet east of the UST location. Locations of on-site water lines were not <br /> positively identified. These would include a 2-inch diameter fire service connection entering <br /> the property from Lindsay Street in the immediate vicinity of the mapped gas service <br /> connection, and shallow landscape irrigation lines. A buried, cast-ii-place electrical <br /> transformer vault is located immediately adjacent to and west of the estimated location of the <br /> USTs. Excavation in this area may be problematic if the vault walls were to be exposed, <br /> unsupported, or undermined during tank removal. A 3-foot diameter cast iron manhole <br /> cover and iron valve box were noted in the area between the USTs and the main building. It <br /> was not possible to open these unlabeled covers, and their function is uncertain. <br /> 3.0 FIELD ACTrVITUES <br /> The objectives of this subsurface soil investigation is to assess the potential presence of <br /> petroleum hydrocarbon impacts soil related to the use of two (2) UST's. The investigation <br /> will be conducted by utilizing a drill ng to advance soil augers and obtain representative soil <br /> samples for analyses. CENII will observe the advancement of three (3) angled soil borings to <br /> 20 feet below ground surface (bgs) and one boring to 10 feet bgs. The 20 foot bonngs will <br /> assess soils adjacent and below the UST's and the 10 foot boring will assess soils adjacent to <br /> the product piping. All work is to be conducted in accordance with California Well <br /> Standards and San Juaqum County Division of Environmental Health specifications. <br /> TECHNICAL APPROACH <br /> To meet the above objectives CEMI will utilize information gathered from the soil boring <br /> advancements which will include soil sampling at 5 foot intervals to a total depth of 10 or 20 <br /> feet bgs (or auger refusal depth). Soil samples will be logged and screened in the field using <br /> an organic vapor meter (OVM). Samples will be analyzed using a stationary state certified <br /> laboratory. <br /> SCOPE OF WORK <br /> Within the approach described above, the scope of work will include the following tasks: <br /> K064M2 HSP 4 <br />
