SAMPLING PROTOCOL FOR ROUTINE PIPING/DISPENSER REMOVAL/REPLACEMENT <br />The following represents minimum sampling criterion required for closure compliance. Soil samples collected shall be <br />representative of native soils beneath the tank's invert (tank's bottom) at a collection depth not to exceed 2 - 4 feet. Samples <br />cannot be combined into a composite sample for analysis in the field or the lab. Each sample must have a set of <br />corresponding analytical results. If contamination is documented during closure, an Unauthorized Release Notification must be <br />completed and submitted within five (5) working days pursuant to California Health & Safety Code, Section 25295. <br />DISPENSER PIPING AND STOCKPILE SAMPLES <br />Dispense <br />S DISPENSER SAMPLES <br />1 Sample beneath each dispenser <br />ach 20ft <br />PIPING SOIL SAMPLES <br />1 Sample every 20 linea1,46et <br />Seg. <br />DISPENSER & PIPING STOCKPILE SAMPLES <br />2 Samples every (Cubic yards <br />TABLE #2 RECOMMENDED MINIMUM VERIFICATJON ANALYSES <br />FOR UNDERGROUND STORAGE TANK INVESTIGATIONS <br />TANK <br />TANK <br />Gasoline <br />Diesel <br />BTEX <br />VOCs <br />Seg. <br />Oil & <br />PCB <br />Total <br />Title 22 <br /># <br />CONTENTS <br />V st <br />Grease <br />Lead <br />Metals (3) <br />8015M <br />8021B <br />8260B <br />8082 <br />7421 <br />82608 <br />8015M <br />8260B <br />8270C <br />1664A <br />Unknown Fuel <br />(C4 -C36) <br />X <br />X <br />X <br />Gasoline <br />X <br />X <br />X <br />(C4 -C20) <br />Diesel <br />X <br />X <br />X <br />(C10—C36) <br />Jet Fuel/Kerosene <br />(C9 -C20) <br />X <br />Heating Oil <br />(C10-032) <br />X <br />X <br />Stoddard Solvent <br />(non-chlorinated)X <br />X <br />C8 -C20 <br />Chlorinated <br />X <br />X <br />Solvents <br />Waste Oil or <br />X <br />X <br />X <br />X <br />X <br />X <br />X <br />Unknown Contents <br />Notes: <br />1.
