1] <br />Ll <br />, T <br />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. If <br />contamination is documented during closure, an Unauthorized Release Notification must be completed and submitted within <br />five (5) working days pursuant to California Health & Safety Code, Section 25295. <br />TABLE #2 RECOMMENDED MINIMUM VERIFICATION ANA ES <br />FOR UNDERGROUND STORAGE TANK INVESTIGAXIOR& <br />TANK TANK TPH-G TPH-D BTX & E CL HC TOTAL M EYD <br />/BA, <br />METALS PCB <br /># CONTENTS LEAD 8270 <br />8015 8015 8020 8010 80 E, ICAP/AES 8080 <br />8260 8260 8260 8240 7420 on <br />or8260 742 B AA <br />LEADED GAS X XX: X <br />UNL GAS X X X <br />DIESEL X X <br />KEROSENE X X X <br />UNK FUEL X X X <br />PROD.
