Soil samples collected shall be <br /> repr entative of native soils beneath the tank's invert (tank's bottom) at a collection depth not to exceed 2 - 4 feet. Samples <br /> canno 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 nd submitted within five (5)working days pursuant to California Health&Safety Code, Section 25295. <br /> DISPENSER PIPING AND STOCKPILE SAMPLES <br /> DIS NSER SAMPLES 1 Sample beneath each ser <br /> PIPING IL SAMPLES 1 Sample every 20 lineal feet UEC a 9 Z016 <br /> DISPENSER PIPING STOCKPILE SAMPLES 2 Samples every 50 cubic yards <br /> LTH <br /> TABLE #2 R COMMENDED MINIMUM VERIFICATION ANALYSES <br /> FOR UNDE ROUND STORAGE TANK INVESTIGATIONS <br /> TANK TANK Gasoline Dies BTEX VOCs(') Semi- Oil& PCB Total Title 22 <br /> # CONTENTS VOCs(') Grease Lead Metals(3) <br /> 8016M 80216 82606 8082 7421 <br /> 82608 8015M 60B 8270C 1664A <br /> Unknown Fuel <br /> (C4-C36) X X X X <br /> Gasoline <br /> (C4-C20) X X X <br /> Diesel <br /> (C10—C36) X X <br /> Jet Fuel/Kerosene <br /> (C9-C20) X X <br /> Heating Oil <br /> (C1X X <br /> 0-C32) <br /> Stoddard Solvent <br /> (non-chlorinated) X X <br /> C8_ 20 <br /> Chlorinated <br /> Solvents X X <br /> Waste Oil or <br /> Unknown Contents X X X X X X X <br /> Notes: <br /> 1.
