Because of the indications of bum material (glass and ash -like <br />material) Kleil,feider has based the chemical analyses partially on the California integrated Waste <br />Management Board (C1WMB) guidance documwt titled LEA Advisory #56, dated November <br />1948. The CIWMB or the Department of Toxic Substances Contra] (DTSC) will often regulate <br />..Burn Duran, sites. <br />Task 1- Stockpile Samplin <br />Kleinfelder is proposing to collect ei ' rte soil sam les from the estimated 50 yams of <br />noterttial mmAcdal. The eight discrete soil samples will be collected at locations <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 suit <br />stockpile_ The samples will be collected by advancing a 2 -inch diameter by 6-irleh long stainless <br />steel sleeve into the stockpile. The stainless steel tube will then be removed from tate stockpile <br />and sealed with Teflon4D sheeting and tight -fitting plastic end caps. Sampling equipmem will be <br />decantaminated between sample locations with a Liquinex4o (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 fmi n and immediately <br />stored in an iced cooler. The samples will be transported -der chain -of -custody control tai <br />Klcinfcldcr's office and then transported by courier in a sealed contain <br />analytical laboratory for chemical analyses. The samples will be valyzed on a standard 10- <br />worKmg day'iurn-uootifid-fime (TAT) Unless an expedited TAT is 'requested at an additional <br />charge. Kleinfelder recommends the two composite samples be analyzed for the following <br />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-DJ by EPA <br />Method 8015M/3015 <br />Total Petroleum 14ytbxx;ubons as referenced to Gasoline [TPH-G) by EPA Method <br />8015M <br />20-YP 1.611/2011 P 163 Page 2 of 6 <br />Copyright 2001, Xleinfcldcr, Fnc.
