s �• <br />Kleinfelder's following sampling and analyses plan is based on the presumption of a screening <br />level assessment of the burn material based on the limited amount of burn -type material <br />uncovered (50 cubic yards). Because of the indications of bum material (glass and ash -like <br />material) Kleinfelder has based the chemical analyses partially on the California Integrated Waste <br />Management Board (CIWMB) guidance document titled LEA Advisory #56, dated November <br />1998. The CIWMB or the Department of Toxic Substances Control (DTSC) will often regulate <br />"Burn Dump" sites. <br />Task 1 — Stockpile Sampling <br />Kleinfelder is proposing to collect eight discrete soil samples from the estimated 50 yards of <br />potential burn material. The eight discrete soil samples will be collected at locations representing <br />approximately equal volumes within the stockpile. After submittal to a state -certified laboratory <br />the eight discrete samples will be composited into two 4 -point composite samples. <br />Soil sampling depths will range from one to three feet below the surface or sides of the soil <br />stockpile. The samples will be collected by advancing a 2 -inch diameter by 6 -inch long stainless <br />steel sleeve into the stockpile. The stainless steel tube will then be removed from the stockpile <br />and sealed with Teflon° sheeting and tight -fitting plastic end caps. Sampling equipment will be <br />decontaminated between sample locations with a Liquinox® (laboratory -grade detergent) and <br />water wash and a distilled water rinse. <br />Task 2 — Chemical Analyses <br />After collection, the samples will be labeled, logged on a chain -of -custody form and immediately <br />stored in an iced cooler. The samples will be transported under chain -of -custody control to <br />Kleinfelder's office and then transported by courier in a sealed container to Sequoia Analytical <br />Laboratory (Sequoia) of Sacramento California. Sequoia is a state certified analytical laboratory <br />for the following requested analyses. The samples will be analyzed on a standard 10 -working <br />day tum -around time (TAT) unless an expedited TAT is requested at an additional charge. <br />Kleinfelder recommends the two composite samples be analyzed for the following analyses: <br />• pH by EPA Method 9040 <br />• Total Threshold Limit Concentrations (TTLCs) of California Assessment Manual (CAM - <br />17) metals by EPA Methods <br />• Benzene, Toluene, Ethylbenzene, Total Xylenes by EPA Method 8020 [BTEX] <br />• Total Extractable Petroleum Hydrocarbons as referenced to Diesel [TPH-D] by EPA <br />Method 8015MJ3015 <br />• Total Petroleum Hydrocarbons as referenced to Gasoline [TPH-G] by EPA Method <br />8015M <br />20-YP 1 -611 /2011 P 181 Page 2 of 6 <br />Copyright 2001, Kleinfelder, Inc.
