�J <br />SAMPLING PROTOCOL FOR ROUTINE PIPING/DISPENSER REMOVALIREPLACEMENT <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 five (5) <br />working days pursuant to California Health & Safety Code, Section 25295. <br />DISPENSER PIPING AND STOCKPILE SAMPLES <br />1 Saple b <br />DISPENSER SAMPLES meneath each dispenser <br />PIPING SOIL SAMPLES 1 Sample every 20 lineal feet <br />D ENSER & PIPING STOCKPILE SAMPLES 2 Samples every 60 cubic ya s <br />TA LE #2 RECOMMENDED MINIMUM VERIFICATION ANAL ES <br />FO NDERGROUND STORAGE TANK INVESTIGA ONS <br />Ivare <br />1.
