• <br />HORIZON ENVIRONMENTAL INC. <br />FIELD METHODS AND PROCEDURES <br />The following section describes field procedures that will be completed by Horizon <br />Environmental Inc. (Horizon) personnel in performance of the tasks involved with <br />this project. <br />1.0 HEALTH AND SAFETY PLAN <br />Field work performed by Horizon and subcontractors at the site will be conducted <br />according to guidelines established in a Site Health and Safety Plan (SHSP). The <br />SHSP is a document that describes the hazards that may be encountered in the <br />field and specifies protective equipment, work procedures, and emergency <br />information. A copy of the SHSP will be at the site and available for reference by <br />appropriate parties during work at the site. <br />2.0 SOIL EXCAVATION AND SAMPLING <br />Samples will be taken from the soil in the backhoe bucket by driving laboratory - <br />cleaned brass sleeves into the soil. The samples will be sealed in the sleeves <br />using Teflon sheets and plastic caps; labeled; and promptly placed in iced storage. <br />If mobile laboratory or field subjective analyses suggest the presence of <br />hydrocarbons in the soil, additional excavation and soil sampling will be performed, <br />using similar methods. <br />Composite characterization samples will be collected from soil stockpile(s) <br />generated at the site. A composite sample is four sample locations (as discrete <br />samples) per composite. The composite characterization samples will be collected <br />from the stockpiled soil by selecting random locations accessible around the soil <br />pile, removing approximately six inches of soil, and driving a clean brass sleeve into <br />the soil pile at the selected location. <br />If groundwater is encountered in the excavation, groundwater grab samples will be <br />collected from the excavation using a clean Teflon bailer. All samples collected will <br />be prepared and chilled for transport under Chain -of -Custody protocol, and sent to <br />Kiff Analytical, a State -certified laboratory in Davis, California (Certification No. <br />2236). <br />Project No. 1602 1 -1 LTCR HORIZON ENVIRONMENTAL INC. <br />
