Samples <br /> canna be combined into a composite sample for analysis in the field or the lab. Each sample must have a set of <br /> corresp ding analytical results. If contamination is documented during closure, an Unauthorized Release Notification must be <br /> completed d submitted within five(5)working days pursuant to California Health&Safety Code, Section 25295. <br /> DISPENSER PIPING AND STOCKPILE SAMPLES <br /> DISP SER SAMPLES 1 Sample beneath each dispenser <br /> PIPING SOlh,AMPLES 1 Sample every 20 FIR t" <br /> 11 DISPENSER &PT T <br /> G STOCKPILE SAMPLES 2 Samples every 50 cubic yards k �� <br /> TABLE #2 REC MENDED MINIMUM VERIFICATION ANki1 eMNMENTAL HEALTH <br /> FOR UNDERG UND STORAGE TANK INVESTIGATION SDEPART MENT <br /> TANK TANK Gasoline Diesel XBTEXVOCsfISemi- Oil& PCB Total Title 22 <br /> # CONTENTS VOCsh) Grease Lead Metals8015M 82606 80827421 <br /> 82606 8015M 8270C 1664A <br /> Unknown Fuel X X � X X <br /> (C4-C36) <br /> Gasoline X <br /> (C4-C20) X X\ <br /> Diesel <br /> (C10—C36) X X X <br /> Jet Fuel/Kerosene <br /> (C9-C20) X X <br /> Heating Oil 7� <br /> (C10-C32) X X <br /> Stoddard Solvent <br /> (non-chlorinated) X X <br /> C8-C20 �. <br /> Chlorinated <br /> Solvents X X <br /> Waste Oil or X X X X \X X X <br /> Unknown Contents <br /> .F <br /> Notes: <br /> 1.
